Rehabilitation

A proactive and goal-oriented activity to restore function and/or to maximize remaining function to bring about the highest possible level of independence, physically, psychologically, socially and economically. It involves combined and coordinated use of medical, nursing and allied health skills, along with social, educational and vocational services, to provide individual assessment, treatment, regular review, discharge planning and follow-up. Rehabilitation is concerned, not only with physical recovery, but also with psychological and social recovery and reintegration (or integration) of the person into the community.... rehabilitation

Relapse

Recurrence of malarial parasitaemia with fresh infection of RBC’s by merozoites derived from hypnozoites in the liver.

Birth Rate

In 2003, 695,500 live births were registered in the United Kingdom; 38 per cent occurred outside marriage. Overall, total fertility is falling slowly. The number of births per 1,000 women aged over 40 years has been rising, and in 1999 was 8.9 per cent. In Great Britain in 2003, 193,817 legal abortions were performed under the Abortion Act 1967.... birth rate

Death Rate

The proportion of deaths in a specified population. The death rate is calculated by dividing the number of deaths in a population in a year by the midyear resident population. Death rates are often expressed as the number of deaths per 100 000 persons. The rate may be restricted to deaths in specific age, race, sex, or geographic groups or deaths from specific causes of death (specific rate), or it may be related to the entire population (crude rate).... death rate

Mortality Rate

See “death rate”.... mortality rate

Nappy Rash

A common form of irritant contact DERMATITIS in the nappy area in babies under one year old. Wetting of the skin by urine, abrasion, and chemical changes due to faecal contamination all play a part. Good hygiene and use of disposable absorbent nappies have much reduced its incidence. An ointment containing a barrier, such as titanium dioxide, may help; other medications such as mild CORTICOSTEROIDS or antibiotics should be used very cautiously and only under the guidance of a doctor, as harmful effects may result – especially from overuse.... nappy rash

Polymyalgia Rheumatica

A form of rheumatism characterised by gross early-morning sti?ness, which tends to ease o? during the day, and pain in the shoulders and sometimes around the hips. It affects women more than men, and is rare under the age of 60. The cause is still obscure. It responds well to PREDNISOLONE, but treatment may need to be long continued. On the other hand the condition is not progressive and does not lead to disability.... polymyalgia rheumatica

Rabies

An almost invariably fatal viral infection of the CNS in mammals. Caused by a rhabdovirus and mostlytransmitted by bite. While there is no effective treatment for the infection, it can be prevented by the use of a human diploid vaccine if given before the onset of symptoms.... rabies

Radial Nerve

This NERVE arises from the BRACHIAL plexus in the axilla. At ?rst descending posteriorly and then anteriorly, it ends just above the elbow by dividing into the super?cial radial and interosseous nerves. It supplies motor function to the muscles which extend the arm, wrist, and some ?ngers, and supplies sensation to parts of the posterior and lateral aspects of the arm, forearm and hand.... radial nerve

Radiation Sickness

The term applied to the nausea, vomiting and loss of appetite which may follow exposure to RADIATION – for example, at work – or the use of RADIOTHERAPY in the treatment of cancer and other diseases. People exposed to radiation at work should have that exposure carefully monitored so it does not exceed safety limits. Doses of radiation given during radiotherapy treatment are carefully measured: even so, patients may suffer side-effects. The phenothiazine group of tranquillisers, such as CHLORPROMAZINE, as well as the ANTIHISTAMINE DRUGS, are of value in the prevention and treatment of radiation sickness.... radiation sickness

Radioactivity

Breakdown of the nuclei of some elements resulting in the emission of energy in the form of alpha, beta and gamma rays. Because of this particle emission, the elements decay into other elements. Radium and uranium are naturally occurring radioactive elements. RADIOTHERAPY treatment utilises arti?cially produced isotopes (alternative forms of an element) such as iodine-131 and cobalt-60.... radioactivity

Radiography

Diagnostic radiography is the technique of examining parts of the body by passing X-RAYS through them to produce images on ?uorescent screens or photographic plates.... radiography

Radioimmunoassay

A technique introduced in 1960 which enables the minute quantities of natural substances in the blood such as HORMONES to be measured. A radioimmunoassay depends upon the ability of an unlabelled hormone to inhibit, by simple competition, the binding of isotopically labelled hormone by speci?c ANTIBODIES. The requirements for a radioimmunoassay include adequate amounts of the hormone; a method for labelling the hormone with a radioactive isotope; the production of satisfactory antibodies; and a technique for separating antibody-bound from free hormone. Radioimmunoassay is more sensitive than the best bioassay for a given hormone, and the most sensitive radioimmunoassays permit the detection of picogram (pg = 10?12g) and femtogram (fg = 10?15g) amounts of material.... radioimmunoassay

Radiology

Radium

The radiations of radium consist of: (1) alpha rays, which are positively charged helium nuclei; (2) beta rays – negatively charged electrons; (3) gamma rays, similar to X-RAYS but of shorter wavelength. These days the use of radium is largely restricted to the treatment of carcinoma of the neck of the womb, the tongue, and the lips. Neither X-rays nor radium supersede active surgical measures when these are available for the complete removal of a tumour.... radium

Ranitidine

An H2-receptor antagonist drug used in the treatment of DUODENAL ULCER by reducing the hyperacidity of the gastric juice. The drug blocks the production of histamine produced by mast cells in the stomach lining. Histamine stimulates the acid-secreting cells in the stomach. Ranitidine, like other H2-blocking drugs, should be used in combination with an antibiotic drug to treat ulcers caused by Helicobacter pylori infection in the stomach. The drug should be given for up to eight weeks with repeat courses if ulcers recur.... ranitidine

Ranula

A swelling which occasionally appears beneath the tongue, caused by a collection of saliva in the distended duct of a salivary gland. (See also MOUTH, DISEASES OF.)... ranula

Rash

See ERUPTION.... rash

Reactive Arthritis

An aseptic (that is, not involving infection) ARTHRITIS secondary to an episode of infection elsewhere in the body. It often occurs in association with ENTERITIS caused by salmonella (see FOOD POISONING) and certain SHIGELLA strains, and in both YERSINEA and CAMPYLOBACTER enteritis. Non-gonococcal urethritis, usually due to CHLAMYDIA, is another cause of reactive arthritis; Reiter’s syndrome is a particularly ?orid form, characterised by mucocutaneous and ocular lesions.

The SYNOVITIS usually starts acutely and is frequently asymmetrical, with the knees and ankles most commonly affected. Often there are in?ammatory lesions of tendon sheaths and entheses (bone and muscle functions) such as plantar fasciitis (see FASCIITIS). The severity and duration of the acute episode are extremely variable. Individuals with the histocompatibility antigen HLA B27 are particularly prone to severe attacks.... reactive arthritis

Receptor

(1) Organs, which may consist of one cell or a small group of cells, that respond to di?erent forms of external or internal stimuli by conveying impulses down nerves to the CENTRAL NERVOUS SYSTEM, alerting it to changes in the internal or external environment.

(2) A small, discrete area on the cell membrane or within the cell with which molecules or molecular complexes (e.g. hormones, drugs, and other chemical messengers) interact. When this interaction takes place it initiates a change in the working of the cell.... receptor

Recessive

Tending to recede. In genetic terms, a recessive gene is one whose expression remains dormant if paired with an unlike allele. The trait will only be manifest in an individual homozygous for the recessive gene. (See GENES.)... recessive

Reactivation of infection; in malaria, renewed manifestation of infection due to survival of RBC forms.... recrudescence

Reduction

The manipulation of part of the body from an abnormal position to the correct one (e.g. fractures, dislocations or hernias).... reduction

Recovery Position

If an individual is unconscious – whether as a result of accident or illness or when in the postoperative recovery unit – but is breathing and has a pulse, he or she should be placed in the recovery position. The individual is turned on his or her side to allow the tongue to fall forwards and so reduce the likelihood of pharyngeal obstruction (see PHARYNX). Fluid in the mouth can also drain outwards instead of into the TRACHEA and LUNGS. The person can lie on either side with upper or lower leg ?exed. Sometimes the semi-prone position is used; this gives better drainage from the mouth and greater stability during transport, but makes it more di?cult to observe the face, colour or breathing. (See APPENDIX 1: BASIC FIRST AID.)... recovery position

Rectum

The last part of the large INTESTINE. It pursues a more or less straight course downwards through the cavity of the pelvis, lying against the sacrum at the back of this cavity. This section of the intestine is about 23 cm (9 inches) long: its ?rst part is freely movable and corresponds to the upper three pieces of the sacrum; the second part corresponds to the lower two pieces of the sacrum and the coccyx; whilst the third part, known also as the anal canal, is about 25 mm (1 inch) long, runs downwards and backwards, and is kept tightly closed by the internal and external SPHINCTER muscles which surround it. The opening to the exterior is known as the ANUS. The structure of the rectum is similar to that of the rest of the intestine.... rectum

Referred Pain

Pain felt in one part of the body which is actually arising from a distant site (e.g. pain from the diaphragm is felt at the shoulder tip). This occurs because both sites develop from similar embryological tissue and therefore have

common pain pathways in the CENTRAL NERVOUS SYSTEM. (See also PAIN.)... referred pain

Refraction

The deviation of rays of light on passing from one transparent medium into another of di?erent density. The refractive surfaces of the EYE are the anterior surface of the cornea (which accounts for approximately two-thirds of the focusing or refractive power of the eye), and the lens (one-third of the focusing power of the eye). The refractive power of the lens can change, whereas that of the cornea is ?xed. (For errors of refraction, see under EYE, DISORDERS OF.)... refraction

Refractory

Resistant to ordinary treatment or infection.... refractory

Regurgitation

Regurgitation is a term used in various connections in medicine. For instance, in diseases of the HEART it is used to indicate a condition in which, as the result of valvular disease, the blood does not entirely pass on from the atria of the heart to the ventricles, or from the ventricles into the arteries. The defective valve is said to be incompetent, and a certain amount of blood leaks past it, or regurgitates back, into the cavity from which it has been driven. (See HEART, DISEASES OF.)

The term is also applied to the return to the mouth of food already swallowed and present in the gullet or stomach (see also REFLUX).... regurgitation

Rejection

A term used in transplant medicine (see TRANSPLANTATION) to describe the body’s immunological response to foreign tissue (see IMMUNITY). Various drugs, such as CICLOSPORIN A, can be used to dampen the host’s response to a graft or organ transplant and reduce the risk of rejection.... rejection

Relapsing Fever

So-called because of the characteristic temperature chart showing recurring bouts of fever, this is an infectious disease caused by SPIROCHAETE. There are two main forms of the disease.

Louse-borne relapsing fever is an EPIDEMIC disease, usually associated with wars and famines, which has occurred in practically every country in the world. For long confused with TYPHUS FEVER and typhoid fever (see ENTERIC FEVER), it was not until the 1870s that the causal organism was described by Obermeier. It is now known as the Borrelia recurrentis, a motile spiral organism 10–20 micrometres in length. The organism is transmitted from person to person by the louse, Pediculus humanus.

Symptoms The incubation period is up to 12 days (but usually seven). The onset is sudden, with high temperature, generalised aches and pains, and nose-bleeding. In about half of cases, a rash appears at an early stage, beginning in the neck and spreading down over the trunk and arms. JAUNDICE may occur; and both the LIVER and the SPLEEN are enlarged. The temperature subsides after ?ve or six days, to rise again in about a week. There may be up to four such relapses (see the introductory paragraph above).

Treatment Preventive measures are the same as those for typhus. Rest in bed is essential, as are good nursing and a light, nourishing diet. There is usually a quick response to PENICILLIN; the TETRACYCLINES and CHLORAMPHENICOL are also e?ective. Following such treatment the incidence of relapse is about 15 per cent. The mortality rate is low, except in a starved population.

Tick-borne relapsing fever is an ENDEMIC disease which occurs in most tropical and sub-tropical countries. The causative organism is Borrelia duttoni, which is transmitted by a tick, Ornithodorus moubata. David Livingstone suggested that it was a tick-borne disease, but it was not until 1905 that Dutton and Todd produced the de?nitive evidence.

Symptoms The main di?erences from the louse-borne disease are: (a) the incubation period is usually shorter, 3–6 days (but may be as short as two days or as long as 12); (b) the febrile period is usually shorter, and the afebrile periods are more variable in duration, sometimes only lasting for a day or two; (c) relapses are much more numerous.

Treatment Preventive measures are more di?cult to carry out than in the case of the louse-borne infection. Protective clothing should always be worn in ‘tick country’, and old, heavily infected houses should be destroyed. Curative treatment is the same as for the louse-borne infection.... relapsing fever

Renin

An ENZYME produced by the kidney (see KIDNEYS) and released into the blood in response to STRESS. Renin reacts with a compound produced by the liver to produce ANGIOTENSIN. This causes blood vessels to constrict and raises the blood pressure. If too much renin is produced, this results in renal HYPERTENSION.... renin

Respiration

The process in which air passes into and out of the lungs so that the blood can absorb oxygen and give o? carbon dioxide and water. This occurs 18 times a minute in a healthy adult at rest and is called the respiratory rate. An individual breathes more than 25,000 times a day and during this time inhales around 16 kg of air.

Mechanism of respiration For the structure of the respiratory apparatus, see AIR PASSAGES; CHEST; LUNGS. The air passes rhythmically into and out of the air passages, and mixes with the air already in the lungs, these two movements being known as inspiration and expiration. INSPIRATION is due to a muscular e?ort which enlarges the chest, so that the lungs have to expand in order to ?ll up the vacuum that would otherwise be left, the air entering these organs by the air passages. The increase of the chest in size from above downwards is mainly due to the diaphragm, the muscular ?bres of which contract and reduce its domed shape and cause it to descend, pushing down the abdominal organs beneath it. EXPIRATION is an elastic recoil, the diaphragm rising and the ribs sinking into the position that they naturally occupy, when muscular contraction is ?nished. Occasionally, forced expiration may occur, involving powerful muscles of the abdomen and thorax; this is typically seen in forcible coughing.

Nervous control Respiration is usually either an automatic or a REFLEX ACTION, each expiration sending up sensory impulses to the CENTRAL NERVOUS SYSTEM, from which impulses are sent down various other nerves to the muscles that produce inspiration. Several centres govern the rate and force of the breathing, although all are presided over by a chief respiratory centre in the medulla oblongata (see under BRAIN – Divisions). This in turn is controlled by the higher centres in the cerebral hemispheres, so that breathing can be voluntarily stopped or quickened.

Quantity of air The lungs do not completely empty themselves at each expiration and re?ll at each inspiration. With each breath, less than one-tenth of the total air in the lungs passes out and is replaced by the same quantity of fresh air, which mixes with the stale air in the lungs. This renewal, which in quiet breathing amounts to about 500 millilitres, is known as the tidal air. By a special inspiratory e?ort, an individual can draw in about 3,000 millilitres, this amount being known as complemental air. By a special expiratory e?ort, too, after an ordinary breath one can expel much more than the tidal air from the lungs – this extra amount being known as the supplemental or reserve air, and amounting to about 1,300 millilitres. If an individual takes as deep an inspiration as possible and then makes a forced expiration, the amount expired is known as the vital capacity, and amounts to around 4,000 millilitres in a healthy adult male of average size. Figures for women are about 25 per cent lower. The vital capacity varies with size, sex, age and ethnic origin.

Over and above the vital capacity, the lungs contain air which cannot be expelled; this is known as residual air, and amounts to another 1,500 millilitres.

Tests of respiratory e?ciency are used to assess lung function in health and disease. Pulmonary-function tests, as they are known, include spirometry (see SPIROMETER), PEAK FLOW METER (which measures the rate at which a person can expel air from the lungs, thus testing vital capacity and the extent of BRONCHOSPASM), and measurements of the concentration of oxygen and carbon dioxide in the blood. (See also LUNG VOLUMES.)

Abnormal forms of respiration Apart from mere changes in rate and force, respiration is modi?ed in several ways, either involuntarily or voluntarily. SNORING, or stertorous breathing, is due to a ?accid state of the soft palate causing it to vibrate as the air passes into the throat, or simply to sleeping with the mouth open, which has a similar e?ect. COUGH is a series of violent expirations, at each of which the larynx is suddenly opened after the pressure of air in the lungs has risen considerably; its object is to expel some irritating substance from the air passages. SNEEZING is a single sudden expiration, which di?ers from coughing in that the sudden rush of air is directed by the soft palate up into the nose in order to expel some source of irritation from this narrow passage. CHEYNE-STOKES BREATHING is a type of breathing found in persons suffering from stroke, heart disease, and some other conditions, in which death is impending; it consists in an alternate dying away and gradual strengthening of the inspirations. Other disorders of breathing are found in CROUP and in ASTHMA.... respiration

Retinoblastoma

A rare malignant growth of the retina (see EYE) which occurs in infants. It can sometimes be discovered at birth because shining a light in the baby’s pupil produces a white re?ection rather than a red one. Alternatively, the infant may present with a SQUINT or a mass in the abdomen. In 25 per cent of cases there is a family history of the condition and abnormality of chromosome 13 is common (see CHROMOSOMES). It is treated by removing the eye or, if affecting both eyes, by laser PHOTOCOAGULATION with or without RADIOTHERAPY.... retinoblastoma

Retrospective Study

A research design used to test hypotheses in which inferences about exposure to the putative causal factor(s) are derived from data relating to characteristics of the persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or other outcome condition of interest, and their characteristics and past experiences are compared with those of other, unaffected persons.... retrospective study

Retrovirus

A VIRUS containing ribonucleic acid (RNA) which is able to change its genetic material into deoxyribonucleic acid (DNA) using an ENZYME called reverse transcriptase. This conversion enables the retrovirus to become integrated into the host cell’s DNA. Retroviruses are believed to be involved in the development of some cancers; they are also associated with disorders linked with an impaired immune system (see IMMUNITY). HIV is a retrovirus.

Retroviruses are also used in the development of gene therapy (see GENETIC ENGINEERING).... retrovirus

Rheumatic Fever

An acute febrile illness, usually seen in children, which may include ARTHRALGIA, ARTHRITIS, CHOREA, carditis (see below) and rash (see ERUPTION). The illness has been shown to follow a beta-haemolytic streptococcal infection (see STREPTOCOCCUS).

Rheumatic fever is now extremely uncommon in developed countries, but remains common in developing areas. Diagnosis is based on the presence of two or more major manifestations – endocarditis (see under HEART, DISEASES OF), POLYARTHRITIS, chorea, ERYTHEMA marginatum, subcutaneous nodules – or one major and two or more minor ones – fever, arthralgia, previous attacks, raised ESR, raised white blood cell count, and ELECTROCARDIOGRAM (ECG) changes. Evidence of previous infection with streptococcus is also a criterion.

Clinical features Fever is high, with attacks of shivering or rigor. Joint pain and swelling (arthralgia) may affect the knee, ankle, wrist or shoulder and may migrate from one joint to another. TACHYCARDIA may indicate cardiac involvement. Subcutaneous nodules may occur, particularly over the back of the wrist or over the elbow or knee. Erythema marginatum is a red rash, looking like the outline of a map, characteristic of the condition.

Cardiac involvement includes PERICARDITIS, ENDOCARDITIS, and MYOCARDITIS. The main long-term complication is damage to the mitral and aortic valves (see HEART).

The chief neurological problem is chorea (St Vitus’s dance) which may develop after the acute symptoms have subsided.

Chronic rheumatic heart disease occurs subsequently in at least half of those who have had rheumatic fever with carditis. The heart valve usually involved is the mitral; less commonly the aortic, tricuspid and pulmonary. The lesions may take 10–20 years to develop in developed countries but sooner elsewhere. The heart valves progressively ?brose and ?brosis may also develop in the myocardium and pericardium. The outcome is either mitral stenosis or mitral regurgitation and the subsequent malfunction of this or other heart valves affected is chronic failure in the functioning of the heart. (see HEART, DISEASES OF).

Treatment Eradication of streptococcal infection is essential. Other features are treated symptomatically. PARACETAMOL may be preferred to ASPIRIN as an antipyretic in young children. One of the NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS) may bene?t the joint symptoms. CORTICOSTEROIDS may be indicated for more serious complications.

Patients who have developed cardiac-valve abnormalities require antibiotic prophylaxis during dental treatment and other procedures where bacteria may enter the bloodstream. Secondary cardiac problems may occur several decades later and require replacement of affected heart valves.... rheumatic fever

Rhinophyma

The condition characterised by swelling of the NOSE due to enormous enlargement of the sebaceous glands which may develop in the later stages of ROSACEA.... rhinophyma

Rhinoplasty

Repair of the NOSE or modi?cation of its shape by operation. This operation is performed by reconstructive and ENT (ear, nose and throat) surgeons alike. It may involve alteration of the bony skeleton of the nose and/or alteration of the SEPTUM (septorhinoplasty). It is mostly performed for cosmetic reasons; however, any disease process or injury which has caused a defect in the nose may be repaired as well. The latter problem would usually involve the utilisation of some form of skin ?ap, whereas this would not be required for cosmetic surgical purposes.... rhinoplasty

Rhinorrhoea

The persistent discharge of watery mucus from the NOSE. This is a usual symptom as a result of COMMON COLD or consequent upon ALLERGY (perennial rhinitis and HAY FEVER).... rhinorrhoea

Rheumatoid Arthritis

A chronic in?ammation of the synovial lining (see SYNOVIAL MEMBRANE) of several joints, tendon sheaths or bursae which is not due to SEPSIS or a reaction to URIC ACID crystals. It is distinguished from other patterns of in?ammatory arthritis by the symmetrical involvement of a large number of peripheral joints; by the common blood-?nding of rheumatoid factor antibody; by the presence of bony erosions around joints; and, in a few, by the presence of subcutaneous nodules with necrobiotic (decaying) centres.

Causes There is a major immunogenetic predisposition to rheumatoid arthritis in people carrying the HLA-DR4 antigen (see HLA SYSTEM). Other minor immunogenetic factors have also been implicated. In addition, there is a degree of familial clustering which suggests other unidenti?ed genetic factors. Genetic factors cannot alone explain aetiology, and environmental and chance factors must be important, but these have yet to be identi?ed.

Epidemiology Rheumatoid arthritis more commonly occurs in women from the age of 30 onwards, the sex ratio being approximately 4:1. Typical rheumatoid arthritis may occur in adolescence, but in childhood chronic SYNOVITIS usually takes one of a number of di?erent patterns, classi?ed under juvenile chronic arthritis.

Pathology The primary lesion is an in?ammation of the synovial membrane of joints. The synovial ?uid becomes diluted with in?ammatory exudate: if this persists for months it leads to progressive destruction of articular CARTILAGE and BONE. Cartilage is replaced by in?ammatory tissue known as pannus; a similar tissue invades bone to form erosions. Synovitis also affects tendon sheaths, and may lead to adhesion ?brosis or attrition and rupture of tendons. Subcutaneous and other bursae may be involved. Necrobiotic nodules also occur at sites outside synovium, including the subcutaneous tissues, the lungs, the pericardium and the pleura.

Clinical features Rheumatoid arthritis varies from the very mild to the severely disabling. Many mild cases probably go undiagnosed. At least 50 per cent of patients continue to lead a reasonably normal life; around 25 per cent are signi?cantly disabled in terms of work and leisure activities; and a minority become markedly disabled and are limited in their independence. There is often an early acute phase, followed by substantial remission, but in other patients gradual step-wise deterioration may occur, with progressive involvement of an increasing number of joints.

The diagnosis of rheumatoid arthritis is largely based on clinical symptoms and signs. Approximately 70 per cent of patients have rheumatoid factor ANTIBODIES in the SERUM but, because of the large number of false positives and false negatives, this test has very little value in clinical practice. It may be a useful pointer to a worse prognosis in early cases if the level is high. X-RAYS may help in diagnosing early cases and are particularly helpful when considering surgery or possible complications such as pathological fracture. Patients commonly develop ANAEMIA, which may be partly due to gastrointestinal blood loss from antiin?ammatory drug treatment (see below).

Treatment involves physical, pharmacological, and surgical measures, together with psychological and social support tailored to the individual patient’s needs. Regular activity should be maintained. Resting of certain joints such as the wrist with splints may be helpful at night or to assist prolonged manual activities. Sound footwear is important. Early use of antirheumatic drugs reduces long-term disability. Drug treatment includes simple ANALGESICS, NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS), and slow-acting drugs including GOLD SALTS (in the form of SODIUM AUROTHIOMALATE), PENICILLAMINE, SULFASALAZINE, METHOTREXATE and AZATHIOPRINE.

The non-steroidal agents are largely e?ective in reducing pain and early-morning sti?ness, and have no e?ect on the chronic in?ammatory process. It is important, especially in the elderly, to explain to patients the adverse effects of NSAIDs, the dosage of which can be cut by prescribing paracetamol at the same time. Combinations of anti-rheumatic drugs seem better than single agents. The slow-acting drugs take approximately three months to act but have a more global e?ect on chronic in?ammation, with a greater reduction in swelling and an associated fall in erythrocyte sedimentation rate (ESR) and rise in the level of HAEMOGLOBIN. Local CORTICOSTEROIDS are useful, given into individual joints. Systemic corticosteroids carry serious problems if continued long term, but may be useful under special circumstances. Much research is currently going on into the use of tumour necrosis factor antagonists such as INFLIXIMAB and etanercept, but their precise role remains uncertain.... rheumatoid arthritis

Ribavirin

Also known as tribavirin, this drug inhibits a wide variety of DNA and RNA viruses. It is administered by inhalation to treat severe BRONCHIOLITIS caused by RESPIRATORY SYNCYTIAL VIRUS (RSV), particularly in infants who also have congenital heart disease. It is not used in uncomplicated bronchiolitis as its bene?ts are arguable in that circumstance: the babies are likely to recover without treatment.

It received its name from the fact that it was ?rst reported in the Rocky Mountain States of the United States; these are still the most heavily infected areas, but the fever is now found in all parts of the US. The causative organism is Rickettsia rickettsi, which is transmitted to humans by tics.... rocky mountain spotted fever

Rorschach Test

A psychological test (see PSYCHOLOGY) for investigating personality and disorders of personality. Also called the ‘ink blot test’, it is now rarely used. It was devised by a Swiss psychiatrist, Hermann Rorschach (1884–1922), who determined individuals’ reactions to a series of symmetrical ink-blots, ten in number and standardised by him.... rorschach test

Rosacea

Common chronic in?ammation of the facial skin, this condition is seen in middle and late life. Redness, obvious dilatation of venules and crops of ACNE-like papules and pustules affect mainly the central forehead, cheeks, nose and chin. A keratoconjunctivitis (combined in?ammation of the cornea and conjunctiva of the EYE) may be associated. Subjects ?ush easily, especially after alcohol or hot drinks. Eventually the affected areas may become thickened and oedematous, and in men, proliferation of ?brous and sebaceous tissue may lead to gross thickening and enlargement of the nose (RHINOPHYMA).

Treatment Long-term, low-dose, oral tetracycline (see ANTIBIOTICS; TETRACYCLINES) is the treatment of choice. In mild cases, METRONIDAZOLE gel can be helpful. Potent topical CORTICOSTEROIDS are contraindicated and make rosacea worse.... rosacea

Roughage

Dietary ?bre is that part of food which cannot be digested in the gastrointestinal tract, although it can be metabolised in the colon by the micro-organisms there. Roughage falls into four groups: cellulose, hemicelluloses, lignins and pectins, found in unre?ned foods such as wholemeal cereals and ?our, root vegetables, nuts and fruit. It has long been known to affect bowel function, probably because of its capacity to hold water in a gel-like form. It plays an important role in the prevention of CONSTIPATION, DIVERTICULOSIS, IRRITABLE BOWEL SYNDROME (IBS), APPENDICITIS, DIABETES MELLITUS and cancer of the colon (see INTESTINE). At present, many western diets do not contain enough roughage.... roughage

Rubella

Rubella, or German measles, is an acute infectious disease of a mild type, which may sometimes be di?cult to di?erentiate from mild forms of MEASLES and SCARLET FEVER.

Cause A virus spread by close contact with infected individuals. Rubella is infectious for a week before the rash appears and at least four days afterwards. It occurs in epidemics (see EPIDEMIC) every three years or so, predominantly in the winter and spring. Children are more likely to be affected than infants. One attack gives permanent IMMUNITY. The incubation period is usually 14–21 days.

Symptoms are very mild, and the disease is not at all serious. On the day of onset there may be shivering, headache, slight CATARRH with sneezing, coughing and sore throat, with very slight fever – not above 37·8 °C (100 °F). At the same time the glands of the neck become enlarged. Within 24 hours of the onset a pink, slightly raised eruption appears, ?rst on the face or neck, then on the chest, and the second day spreads all over the body. The clinical signs and symptoms of many other viral infections are indistinguishable from rubella so a precise diagnosis cannot be made without taking samples (such as saliva) for antibody testing, but this is rarely done in practice.

An attack of German measles during the early months of pregnancy may be responsible for CONGENITAL defects in the FETUS (for information on fetal abnormalities, see under PREGNANCY AND LABOUR). The incidence of such defects is not precisely known, but probably around 20 per cent of children whose mothers have had German measles in the ?rst three months of the pregnancy are born with congenital defects. These defects take a variety of forms, but the most important ones are: low birth weight with retarded physical development; malformations of the HEART; cataract (see under EYE, DISORDERS OF); and DEAFNESS.

Treatment There is no speci?c treatment. Children who develop the disease should not return to school until they have recovered, and in any case not before four days have passed from the onset of the rash.

In view of the possible dangerous e?ect of the disease upon the fetus, particular care should be taken to isolate pregnant mothers from contact with infected subjects. As the risk is particularly high during the ?rst 16 weeks of pregnancy, any pregnant mother exposed to infection during this period should be given an intramuscular injection of GAMMA-GLOBULIN. A vaccine is available to protect an individual against rubella (see IMMUNISATION).

In the United Kingdom it is NHS policy for all children to have the combined measles, mumps and rubella vaccine (see MMR VACCINE), subject to parental consent. All women of childbearing age, who have been shown by a simple laboratory test not to have had the disease, should be vaccinated, provided that the woman is not pregnant at the time and has not been exposed to the risk of pregnancy during the previous eight weeks.... rubella

X-rays

Also known as Röntgen rays, these were discovered in 1895 by Wilhelm Conrad Röntgen. Their use for diagnostic imaging (radiology) and for cancer therapy (see RADIOTHERAPY) is now an integral part of medicine. Many other forms of diagnostic imaging have been developed in recent years, sometimes also loosely called ‘radiology’. Similarly the use of chemotherapeutic agents in cancer has led to the term oncology which may be applied to the treatment of cancer by both drugs and X-rays.

The rays are part of the electro-magnetic spectrum; their wavelengths are between 10?9 and 10? 13 metres; in behaviour and energy they are identical to the gamma rays emitted by radioactive isotopes. Diagnostic X-rays are generated in an evacuated tube containing an anode and cathode. Electrons striking the anode cause emission of X-rays of varying energy; the energy is largely dependent on the potential di?erence (kilovoltage) between anode and cathode. The altered tissue penetration at di?erent kilovoltages is used in radiographing di?erent regions, for example in breast radiography (25–40 kV) or chest radiography (120–150 kV). Most diagnostic examinations use kilovoltages between 60 and 120. The energy of X-rays enables them to pass through body tissues unless they make contact with the constituent atoms. Tissue attenuation varies with atomic structure, so that air-containing organs such as the lung o?er little attenuation, while material such as bone, with abundant calcium, will absorb the majority of incident X-rays. This results in an emerging X-ray pattern which corresponds to the structures in the region examined.

Radiography The recording of the resulting images is achieved in several ways, mostly depending on the use of materials which ?uoresce in response to X-rays. CONTRAST X-RAYS Many body organs are not shown by simple X-ray studies. This led to the development of contrast materials which make particular organs or structures wholly or partly opaque to X-rays. Thus, barium-sulphate preparations are largely used for examining the gastrointestinal tract: for example, barium swallow, barium meal, barium follow-through (or enteroclysis) and barium enema. Water-soluble iodine-containing contrast agents that ionise in solution have been developed for a range of other studies.

More recently a series of improved contrast molecules, chie?y non-ionising, has been developed, with fewer side-effects. They can, for example, safely be introduced into the spinal theca for myeloradiculography – contrast X-rays of the spinal cord. Using these agents, it is possible to show many organs and structures mostly by direct introduction, for example via a catheter (see CATHETERS). In urography, however, contrast medium injected intravenously is excreted by the kidneys which are outlined, together with ureters and bladder. A number of other more specialised contrast agents exist: for example, for cholecystography – radiological assessment of the gall-bladder. The use of contrast and the attendant techniques has greatly widened the range of radiology. IMAGE INTENSIFICATION The relative insensitivity of ?uorescent materials when used for observation of moving organs – for example, the oesophagus – has been overcome by the use of image intensi?cation. A faint ?uorographic image produced by X-rays leads to electron emission from a photo-cathode. By applying a high potential di?erence, the electrons are accelerated across an evacuated tube and are focused on to a small ?uorescent screen, giving a bright image. This is viewed by a TV camera and the image shown on a monitor and sometimes recorded on videotape or cine. TOMOGRAPHY X-ray images are two-dimensional representations of three-dimensional objects. Tomography (Greek tomos

– a slice) began with X-ray imaging produced by the linked movement of the X-ray tube and the cassette pivoting about a selected plane in the body: over- and underlying structures are blurred out, giving a more detailed image of a particular plane.

In 1975 Godfrey Houns?eld introduced COMPUTED TOMOGRAPHY (CT). This involves

(i) movement of an X-ray tube around the patient, with a narrow fan beam of X-rays; (ii) the corresponding use of sensitive detectors on the opposite side of the patient; (iii) computer analysis of the detector readings at each point on the rotation, with calculation of relative tissue attenuation at each point in the cross-sectional plant. This invention has enormously increased the ability to discriminate tissue composition, even without the use of contrast.

The tomographic e?ect – imaging of a particular plane – is achieved in many of the newer forms of imaging: ULTRASOUND, magnetic resonance imaging (see MRI) and some forms of nuclear medicine, in particular positron emission tomography (PET SCANNING). An alternative term for the production of images of a given plane is cross-sectional imaging.

While the production of X-ray and other images has been largely the responsibility of radiographers, the interpretation has been principally carried out by specialist doctors called radiologists. In addition they, and interested clinicians, have developed a number of procedures, such as arteriography (see ANGIOGRAPHY), which involve manipulative access for imaging – for example, selective coronary or renal arteriography.

The use of X-rays, ultrasound or computerised tomography to control the direction and position of needles has made possible guided biopsies (see BIOPSY) – for example, of pancreatic, pulmonary or bony lesions – and therapeutic procedures such as drainage of obstructed kidneys (percutaneous nephrostomy), or of abscesses. From these has grown a whole series of therapeutic procedures such as ANGIOPLASTY, STENT insertion and renal-stone track formation. This ?eld of interventional radiology has close a?nities with MINIMALLY INVASIVE SURGERY (MIS).

Radiotherapy, or treatment by X-rays The two chief sources of the ionising radiations used in radiotherapy are the gamma rays of RADIUM and the penetrating X-rays generated by apparatus working at various voltages. For super?cial lesions, energies of around 40 kilovolts are used; but for deep-seated conditions, such as cancer of the internal organs, much higher voltages are required. X-ray machines are now in use which work at two million volts. Even higher voltages are now available through the development of the linear accelerator, which makes use of the frequency magnetron which is the basis of radar. The linear accelerator receives its name from the fact that it accelerates a beam of electrons down a straight tube, 3 metres in length, and in this process a voltage of eight million is attained. The use of these very high voltages has led to the development of a highly specialised technique which has been devised for the treatment of cancer and like diseases.

Protective measures are routinely taken to ensure that the patient’s normal tissue is not damaged during radiotherapy. The operators too have to take special precautions, including limits on the time they can work with the equipment in any one period of time.

The greatest value of radiotherapy is in the treatment of malignant disease. In many patients it can be used for the treatment of malignant growths which are not accessible to surgery, whilst in others it is used in conjunction with surgery and chemotherapy.... x-rays

Hormone Replacement Therapy (hrt)

Within a few years medical scientists have introduced into the domestic scene a steroid which has changed the whole course of female history. HRT has solved some basic medical problems by making good the loss of oestrogen in a woman’s body when menstruation is finished and her body learns to adjust.

A lack of oestrogen induces hot flushes, night sweats, thinning of the bones (osteoporosis) with possible fractures, and a wide range of physical and emotional disorders.

HRT also prevents the increased frequency of coronary disease which may follow the menopause. With oestrogen only, HRT appears to increase the incidence of cancer of the uterine body. Use of oestrogen and progestogen avoids this.

HRT is available as a tablet, transdermal patch, implant or topical cream. Most women notice temporary improvement in their appearance and hot flushes as long as treatment is continued. HRT is not prescribed by the herbal practitioner. Soya and Hops are a mild alternative.

Side-effects of such treatment include blood pressure rise, weight gain and periods probably continue with a monthly bleed. Elderly women taking HRT for osteoporosis may develop bleeding problems, the risk of blood clot and gall bladder diseases.

Helonias has proved a useful alternative, effective in eliminating excess fluids, reducing hot flushes, and relieving that bloated feeling, thus helping the older woman to live a normal life.

Damiana. 1 heaped teaspoon leaves to each cup boiling water; infuse 5-10 minutes; strain. 1 cup 2-3 times daily for 3-6 weeks.

Sarsaparilla. 1oz (30g) root in 1 pint (500ml) water; simmer gently 20 minutes; strain. 1 cup 2-3 times daily for 3-6 weeks.

Supplementation. Daily. Vitamin E, 400iu. Vitamin B-complex (high potency). Evening Primrose oil capsules, 500mg morning and evening. Dolomite, for Calcium and Magnesium, 2 tablets morning and evening.

Note: An extensive study of breast cancer risks with HRT revealed a positive link between the risk of cancer and length of use. Risk of the disease increased with all types of women using HRT with every year of use. Pre-menstrual women were more than twice at risk. It would appear that oestrogens cannot be taken without risk.

Gravel Root

Eupatorium purpureum. N.O. Compositae.

Synonym: Eupatorium purpureum is also called Gravel Weed and Queen of the

Meadow, from which the medicinal "Gravel Root" is obtained.

Habitat: Gravel Root is a native of the United States, and must not be confused with the English Queen of the Meadow or Meadowsweet (Spiraea ulmaria).

Features ? Our present subject is a member of the Boneset (Eupatorium perfoliatum) family, and sometimes reaches six feet in height at full growth. It is peculiar for a purple band about an inch broad round the leaf joint. Pale purple to white flowers bloom in August and September. The rhizome, as the medicinal "root" should more properly be termed, is hard and tough, up to an inch thick, with a nearly white wood and thin grey-brown bark. Short, lateral branches give off thin, tough root several inches long.

Part used ? Root.

Action: Diuretic and stimulant.

Gravel root is much prescribed for cases of stone in the bladder and certain other troubles of the kidneys and urinary apparatus. A decoction of 1 ounce of the root to 1 pint (reduced from 1 1/2 pints) of water is made, and taken in wineglass doses. Gravel root is also met with in nervine formulae, in which its tonic properties are recognised.

The American physio-medical or "Thomsonite" M.D., F. H. England, has said that Gravel Root "induces very little stimulation. It expends nearly all its influence on the kidneys, bladder and uterus. It probably influences the whole sympathetic nervous system. Its use promotes the flow of urine as scarcely anything else will."... gravel root

Radiation

Energy in the form of waves or particles. Radiation is mainly electromagnetic and is broadly classi?ed as ionising and non-ionising. The former can propel ions from an atom; these have an electrical charge and can combine chemically with each other. Ionisation occurring in molecules that have a key function in living tissue can cause biological damage which may affect existing tissue or cause mutations in the GENES of germ-cell nuclei (see GAMETE; CELLS). Non-ionising radiation agitates the constituent atoms of nuclei but is insu?ciently powerful to produce ions.

Ionising radiation comprises X-RAYS, GAMMA RAYS and particle radiation. X-rays are part of the continuous electromagnetic-wave spectrum: this also includes gamma rays, infra-red radiation, ultraviolet light and visible light. They have a very short wavelength and very high frequency, and their ability to penetrate matter depends upon the electrical energy generating them. X-rays that are generated by 100,000 volts can pass through body tissue and are used to produce images – popularly known as X-rays. X-rays, generated at several million volts can destroy tissue and are used in RADIOTHERAPY for killing cancer cells. Gamma rays are similar to X-rays but are produced by the decay of radioactive materials. Particle radiation, which can be produced electrically or by radioactive decay, comprises parts of atoms which have mass as well as (usually) an electrical charge.

Non-ionising radiation includes ultraviolet light, radio waves, magnetic ?elds and ULTRASOUND. Magnetic ?elds are used in magnetic resonance imaging (MRI) and ultrasound, which is inaudible high-frequency sound waves, and is used for both diagnoses and treatment in medicine.... radiation

Rape

A criminal o?ence in which sexual intercourse takes place with an unwilling partner, female or male, under threat of force or violence. Reported rape cases have increased in number in recent years, but it is hard to know whether this is because the incidence of rape has increased or because the victims – women and men – are more willing to report the crime. A more sympathetic and understanding approach by the police, courts and society generally has resulted in the provision of greater support for victims who are usually severely traumatised psychologically as well as physically. It is argued that rape is motivated by a desire to dominate rather than simply an attempt to achieve sexual grati?cation. The majority of rapes are probably unreported because of the victims’ shame, anxiety about publicity and fear that the rapist will take reprisals. It is legally recognised that rape can happen within marriage. There are moves to make court proceedings less traumatic for victims, whose attackers are often known to them.

Anxiety, DEPRESSION and POST-TRAUMATIC STRESS DISORDER (PTSD) are common after rape: many victims are now given help by rape crisis counselling. A recent report suggests that in at least 50 per cent of reported rapes, the attacker was known to, or had been a friend of, the victim. The deliberate misuse of alcohol or drugs to reduce a potential victim’s resistance seems to be increasing (see DRUG ASSISTED RAPE; FLUNITRAZEPAM.)... rape

Rates are usually expressed using a standard denominator such as 1000 or 100 000 persons. Rates may also be expressed as percentages. The use of rates rather than raw numbers is essential for comparison of experience between populations at different times or in different places, or among different classes of persons.... rate

Reed

Phragmites australis

Description: This tall, coarse grass grows to 3.5 meters tall and has gray-green leaves about 4 centimeters wide. It has large masses of brown flower branches in early summer. These rarely produce grain and become fluffy, gray masses late in the season.

Habitat and Distribution: Look for reed in any open, wet area, especially one that has been disturbed through dredging. Reed is found throughout the temperate regions of both the Northern and Southern Hemispheres.

Edible Parts: All parts of the plant are edible raw or cooked in any season. Harvest the stems as they emerge from the soil and boil them. You can also harvest them just before they produce flowers, then dry and beat them into flour. You can also dig up and boil the underground stems, but they are often tough. Seeds are edible raw or boiled, but they are rarely found.... reed

A milk-coagulating ENZYME produced by the lining of the stomach. Rennin converts milk protein (caseinogen) into insoluble casein, thus ensuring that milk stays in the stomach for some time, during which it can be digested by various enzymes before passing into the small intestine.... rennin

Replication

Research that attempts to reproduce the findings of previous investigators so as to increase confidence in (or refute) those findings.... replication

Representative Sample

The term “representative”, as it is commonly used, is undefined in the statistical or mathematical sense; it means simply that the sample resembles the population in some way. The use of probability sampling will not ensure that any single sample will be “representative” of the population in all possible aspects. A common fallacy lies in the unwarranted assumption that, if the sample resembles the population closely on those factors that have been checked, it is “totally representative” and no differences exist between the sample and the universal or reference population.... representative sample

Reproductive System

A collective term for all the organs involved in sexual reproduction. In the female these are the OVARIES, FALLOPIAN TUBES, UTERUS, VAGINA and VULVA. In the male these are the testes (see TESTICLE), VAS DEFERENS, SEMINAL VESICLES, URETHRA and PENIS.... reproductive system

Reserpine

An alkaloid (see ALKALOIDS) obtained from the root of rauwol?a that has been and continues to be used as an anti-hypertensive (see HYPERTENSION) and a tranquillising agent.... reserpine

The amount of air left in the LUNGS after an individual has breathed out as much as possible. It is a measure of lung function: for example, in a person with EMPHYSEMA the residual volume is increased. (See RESPIRATION; LUNG VOLUMES.)... residual volume

Resins

These are wax-containing plant oils, often secreted to fill in injured tissues, much like a blood clot, sometimes used to protect leaves from loss of water through evaporation or to render them unpalatable. (See BALSAMICS.)... resins

Resolution

A term applied to infective processes, to indicate a natural subsidence of the INFLAMMATION without the formation of PUS. Thus a pneumonic lung is said to ‘resolve’ when the material exuded into it is absorbed into the blood and lymph, so that recovery takes place naturally; an in?amed area is said to resolve when the in?ammation diminishes and no abscess forms; a glandular enlargement is said to resolve when it decreases in size without suppuration. Resolution is also used to describe the extent to which individual details – for example, cell structures – can be identi?ed by the eye when using a light microscope.... resolution

Resolvent

Causing resolution of a tumour or swelling... resolvent

Respiratory Distress Syndrome

This may occur in adults as ACUTE RESPIRATORY DISTRESS SYNDROME (ARDS), or in newborn children, when it is also known as HYALINE MEMBRANE DISEASE. The adult syndrome consists of PULMONARY OEDEMA of non-cardiac origin. The process begins when tissue damage stimulates the autonomic nervous system, releases vasoactive substances, precipitates complement activation, and produces abnormalities of the clotting cascade – the serial process that leads to clotting of the blood (see COAGULATION). The activation of complement causes white cells to lodge in the pulmonary capillaries where they release substances which damage the pulmonary endothelium.

Respiratory distress syndrome is a complication of SHOCK, systemic SEPSIS and viral respiratory infections. It was ?rst described in 1967, and – despite advances with assisted ventilation

– remains a serious disease with a mortality of more than 50 per cent. The maintenance of adequate circulating blood volume, peripheral PERFUSION, acid-base balance and arterial oxygenation is important, and assisted ventilation should be instituted early.

In newborns the mechanism is diferent, being provoked by an inability of the lungs to manufacture SURFACTANT.... respiratory distress syndrome

Restless Legs Syndrome

A condition in which the patient experiences unpleasant sensations, and occasionally involuntary movements, in the legs when at rest, especially at night. No pathological changes have been identi?ed. It is sometimes indicative of iron-de?ciency ANAEMIA, but in many cases the cause remains a mystery and the variety of cures o?ered are a testimony to this. Some anti-epileptic drugs are said to help (see EPILEPSY).... restless legs syndrome

Revalidation

The periodic assessment of a doctor’s professional competence. Revalidation began in the UK in 2004, to ensure that those doctors on the Medical Register of the GENERAL MEDICAL COUNCIL (GMC) as active practitioners are capable of providing appropriate standards of medical care. The process depends, amongst other things, upon the doctor being able to demonstrate that he or she has maintained a continuing programme of professional development: ‘lifelong learning’.... revalidation

Ribonucleic Acid

See RNA.... ribonucleic acid

Ribosome

Granules either found free within the cell, or attached to a reticular network within the cell’s endoplasm (the inner part of a cell’s cytoplasm

– see CELLS). Consisting of approximately 65 per cent RNA and 35 per cent PROTEIN, they are the sites where protein is made.... ribosome

Ribozyme

Sections of deoxyribonucleic acid (DNA) – the principal molecule in a cell carrying genetic information – that act as enzymes (see ENZYME). The function of a ribozyme is to transform the messages encoded in DNA into proteins (see PROTEIN), using its property of catalysing chemical reactions in a cell. Most ribozymes act only on other pieces of ribonucleic acid (RNA), editing the messenger type that carries instructions to the parts of the cell that makes proteins. This editing ability is being used by scientists researching ways of correcting faulty GENES which can cause inherited disorders. The aim is to persuade the ribozyme to inhibit the messenger RNA to prevent production of the faulty gene. Ribozymes might also be used to disrupt infectious agents, such as viruses, which rely on RNA to invade body cells.... ribozyme

Rift Valley Fever

A virus disease, caused by a phlebovirus and transmitted by mosquitoes, at one time con?ned to sub-Saharan Africa and predominantly found in domestic animals such as cattle, sheep and goats. The only humans affected were veterinary surgeons, butchers and others exposed to heavy infection by direct contact with infected animals; these usually recovered. In the 1970s the disease ?ared up in Egypt, probably owing to a more virulent virus. The illness in humans is characterised by fever, haemorrhages, ENCEPHALITIS and involvement of the EYE. An e?ective vaccine protects both animals and human beings against the disease (see IMMUNISATION).... rift valley fever

Rickettsia

The general term given to a group of microorganisms which are intermediate between BACTERIA and viruses (see VIRUS). They are the causal agents of TYPHUS FEVER and a number of typhus-like diseases, such as ROCKY MOUNTAIN SPOTTED FEVER, Japanese River fever, and scrub typhus. These micro-organisms are usually conveyed to man by lice, ?eas, ticks, and mites.

Visceral rickettsia is a disease transmitted by mites from an infected house mouse, which occurs in the USA, South Africa, Korea and the former Soviet Union. The causal organism is Rickettsia akari. The incubation period is 7–14 days and the characteristic features are fever, headache, and a non-irritating rash on the face, trunk and extremities. The disease is non-fatal and responds rapidly to TETRACYCLINES.... rickettsia

Rifampicin

An antibiotic derived from Streptomyces mediterranei, rifampicin is a key component of the treatment of TUBERCULOSIS. Like ISONIAZID, it should always be included unless there is a speci?c contraindication. It is also valuable in the treatment of BRUCELLOSIS, LEGIONNAIRE’S DISEASE, serious staphylococcal (see STAPHYLOCOCCUS) infections and LEPROSY. It is also given to contacts of certain forms of childhood MENINGITIS.

Rifampicin is given by mouth; during the ?rst two months it often causes transient disturbance of LIVER function, with raised concentrations of serum transaminases, but usually treatment need not be interrupted. In patients with pre-existing liver disease more severe toxicity may occur, and liver function should be carefully monitored both before starting and during rifampicin treatment. It induces hepatic enzymes which accelerate the metabolism of various drugs including ANTICOAGULANTS, SULPHONYLUREAS, PHENYTOIN SODIUM, CORTICOSTEROIDS and OESTROGENS. The e?ectiveness of oral contraceptives is reduced and alternative family-planning advice should be o?ered.

Rifampicin should be avoided during pregnancy and breast feeding, and extra caution should be applied if there is renal impairment, JAUNDICE or PORPHYRIAS. Adverse effects include gastrointestinal symptoms, in?uenza-like symptoms, collapse and SHOCK, haemolytic ANAEMIA, acute ?ushing and URTICARIA; body secretions may be coloured red.... rifampicin

Risk Register

The term is used in two ways. Firstly, it may comprise a list of infants whose obstetric and/or perinatal history suggests they might be at risk of illness or serious abnormality such as LEARNING DISABILITY.

Secondly – and more commonly termed the ‘At-risk register’ – this is a list held by social-service departments, and accessible to doctors in A&E departments, of children whom a local-authority social-services case conference has deemed to have been harmed or to be at risk of harm from mental, physical or sexual abuse (see also CHILD ABUSE).... risk register

Rouleau

A group of red blood cells arranged together like a roll of coins, usually only noticed on a slide under a microscope. Since red blood cells in a reasonably healthy person should have a mutually repelling membrane charge, this means that something like an inflammatory response or an elevation of liver-synthesized lipids (LDLs and VLDLs) is occurring. Inflammation makes the blood “sticky,” and the lipids from the liver lower the charges. Remember, of course, that I am talking about subclinical imbalances...such things as rouleau can accompany some pretty gnarly diseases. Our kind of rouleau can give you a headache or make your hands and feet cold because it’s hard to push rolls of coins through little bitty capillaries.... rouleau

Artificial Respiration

Forced introduction of air into the lungs of someone who has stopped breathing (see respiratory arrest) or whose breathing is inadequate. As an emergency first-aid measure, artificial respiration can be given mouth-to-mouth or mouth-tonose, which can prevent brain damage due to oxygen deprivation; a delay in breathing for more than 6 minutes can cause death. Cardiac compressions may also be necessary if poor respiration has led to cessation of the heartbeat (see cardiopulmonary resuscitation). Artificial respiration can be continued by use of a ventilator (see ventilation).... artificial respiration

Cardiopulmonary Resuscitation

The administration of life-saving measures to a person who has suffered a cardiac arrest. A person in cardiac arrest is not breathing and has no detectable pulse or heartbeat. First, mouth-to-mouth resuscitation (see artificial respiration) is given; if this fails to restart breathing, repeated chest compressions, using the heel of

the hand, are applied to the lower breastbone until trained help arrives.

Both these measures are used to restore blood circulation to the brain.

Brain damage is likely if the brain is starved of oxygen for more than 3–4 minutes.... cardiopulmonary resuscitation

Roseola

R. infantum. ‘Rash of Roses’ consists of small separate irregular rose-pink spots with a pale halo which appears after feverishness has abated. Spots that fade on pressure first appear on trunk and neck, spreading to the face and buttocks, remaining for a short duration – half to 2 days. This is the commonest cause of high fever in children under three. Causal agent: herpes virus, human, HH6. Differential diagnosis: from German Measles where rash accompanies fever. Internally: German Chamomile tea freely. See: SKIN, above entry.

Teething. Teas: Spearmint, Roman Chamomile, Peppermint. 1 heaped teaspoon to cup boiling water; infuse 15 minutes; frequent teaspoon doses. Alternative: place one Chamomile flower in feeding bottle. Essential oils: rub gums with diluted oils: Spearmint, German Chamomile, Peppermint or Mullein. Urinary Tract Infection, Cystitis or urethritis.

Teas: Horsetail, Couch Grass, Golden Rod, Rosehip. Dandelion coffee. For pus in the urine: 1-5 drops Tincture Myrrh in cup of warm water: Dose: 1-2 teaspoons thrice daily. Fullness under the eyes may indicate Bright’s Disease for which specialist opinion should be obtained without delay.

Diet. Wholegrain cereals, wholemeal bread, pasta, two servings fresh fruit and vegetables daily. Little lean meat, poultry, fish. Dairy products: yoghurt, cheese, milk in moderation. Fresh orange juice, raw fresh vegetable salads. Oatmeal (porridge oats) is sustaining to the nervous system.

Avoid: crisps, fizzy drinks, hamburgers, biscuits, chocolate, sugar-filled snacks, alcohol, strong tea and coffee.

Supplement. Most children may benefit from one zinc tablet weekly.

Medicine doses. See: DOSAGE.

Fish oils. As well as to help children guard against winter illnesses, Cod Liver oil supplements may help them later in life against arthritis, heart disease, psoriasis, eczema and other inflammatory disorders.

Aspirin. It is clear that a link exists between Reye’s syndrome and aspirin. Aspirin is not advised for minor viral illness in children. ... roseola

Free Radicals

Both vegetable and animal tissues produce free radicals as a normal metabolic byproduct. They are found in many areas of human activity.

A radical is a group of atoms which can combine in the same way as single atoms to make a molecule. Free means uncombined. A free radical is a state in which a radical can exist before it combines – an incomplete molecule containing oxygen which has an uneven electrical charge. High energy oxygen atoms are known to form atheroma.

As well as being substances that take part in a process of metabolism, free radicals can be found in industrial fumes and cigarette smoke. They are oxidants and have an anti-bacterial effect. But their activity is not confined to bacteria alone. When produced in large amounts as in inflammation and infection, they may have a damaging effect upon the lining of blood vessels and other tissues. An excess is produced in ischaemic heart disease. They have been shown to be involved in jet lag, Alzheimer’s disease, rheumatoid arthritis, thrombosis, heart failure, cancer, irradiation sickness and a weak immune system. Damaging to the DNA, they are probably the greatest single cause of ill health. They hasten the ageing process. Vitamins A, C, E, being antioxidants and the mineral Selenium stimulate certain enzyme systems to limit damage done by these destructive elements.

Losing weight is believed to generate free radicals – a metabolic side-effect of dieting. See: ANTIOXIDANTS. ... free radicals

C-reactive Protein

Hip Replacement

A surgical procedure to replace all or part of a diseased hip joint with an artificial substitute. The replacement is most often carried out in older people whose joints are stiff and painful as a result of osteoarthritis. It may also be needed if rheumatoid arthritis has spread to the hip joint or if the top end of the femur is badly fractured (see femur, fracture of).... hip replacement

Immune Response

The body’s defensive reaction to microorganisms, cancer cells, transplanted tissue, and other substances or materials that are recognized as antigenic or “foreign”.

The response consists of the production of cells called lymphocytes, substances called antibodies, or immunoglobulins, and other substances and cells that act to destroy the antigenic material.

Raynaud’s Disease

A disorder of the blood vessels in which exposure to cold causes the small arteries supplying the fingers and toes to contract suddenly. This cuts off blood flow to the digits, which become pale. The fingers are more often affected than the toes. The cause is unknown, but young women are most commonly affected.

On exposure to cold, the digits turn white due to lack of blood. As sluggish blood flow returns, the digits become blue; when they are warmed and normal blood flow returns, they turn red. During an attack, there is often tingling, numbness, or a burning feeling in the affected fingers or toes. In rare cases, the artery walls gradually thicken, permanently reducing blood flow. Eventually painful ulceration or even gangrene may develop at the tips of the affected digits.

Diagnosis is made from the patient’s history. Treatment involves keeping the hands and feet as warm as possible. Vasodilator drugs or calcium channel blockers may be helpful in severe cases. (See also Raynaud’s phenomenon.)... raynaud’s disease

Rectal Bleeding

The passage of blood from the rectum or anus. The blood may be red, dark brown, or black. It may be mixed with, or on the surface of, faeces or passed separately, and there may be pain. Haemorrhoids are the most common cause of rectal bleeding. Small amounts of bright red blood appear on the surface of faeces or on toilet paper. Anal fissure, anal fistula, proctitis, or rectal prolapse may also cause rectal bleeding.Cancer of the colon (see colon, cancer of) or the rectum (see rectum, cancer of), or polyps can also cause bleeding. Disorders of the colon such as diverticular disease may cause dark red faeces. Black faeces (melaena) may be due to bleeding high in the digestive tract. Bloody diarrhoea may be due to ulcerative colitis, amoebiasis, or shigellosis. Diagnosis may be made from a rectal examination, from proctoscopy, sigmoidoscopy, colonoscopy, or a double-contrast barium X-ray examination.

rectal examination Examination of the anus and rectum, performed as part of a general physical examination, to assess symptoms of pain or changes in bowel habits, and to check for the presence of tumours of the rectum or prostate gland. rectal prolapse Protrusion outsid.

Treatment is with a fibre-rich diet.

Surgery may also be performed.... rectal bleeding

Reflex

An action that occurs automatically and predictably in response to a particular stimulus, independent of the will of the individual.

In the simplest reflex, a sensory nerve cell reacts to a stimulus, such as heat or pressure, and sends a signal along its nerve fibre to the central nervous system. There, another nerve cell becomes stimulated and causes a muscle to contract or a gland to increase its secretory activity. The passage of the nerve signal.

from original sensation to final action is called a reflex arc.

Reflexes may be inborn or conditioned. Some inborn reflexes occur only in babies (see reflex, primitive). Inborn reflexes include those that control basic body functions, such as contraction of the bladder after it has filled beyond a certain point, and are managed by the autonomic nervous system. Conditioned reflexes are acquired through experience in a process called conditioning.

Several simple reflexes, such as the knee-jerk, are tested in a physical examination. Changes in the reflexes may indicate damage to the nervous system. The examination of vital reflexes controlled by the brainstem is the basis for diagnosing brain death.... reflex

Reiter’s Syndrome

A condition in which there is a combination of urethritis, reactive arthritis, and conjunctivitis. There may also be uveitis. Reiter’s syndrome is more common in men.

The syndrome is caused by an immune response and usually develops only in people with a genetic predisposition. Most patients have the -B27 tissue type (see histocompatability antigens). The syndrome’s development is induced by infection: usually nongonococcal urethritis, but sometimes bacillary dysentery. Reiter’s syndrome usually starts with a urethral discharge, which is followed by conjunctivitis and then arthritis. The arthritis usually affects 1 or 2 joints (usually the knee and/or ankle) and is often associated with fever and malaise. Attacks can last for several months. Tendons, ligaments, and tissue in the soles of the feet may also become inflamed. Skin rashes are common.

Diagnosis is made from the symptoms.

Analgesic drugs and nonsteroidal antiinflammatory drugs relieve symptoms but may have to be taken for a long period.

Relapses occur in about 1 in 3 cases.... reiter’s syndrome

Renal Tubular Acidosis

A condition in which the kidneys are unable to excrete normal amounts of acid made by the body.

The blood is more acidic than normal, and the urine less acidic.

Causes include kidney damage due to disease, drugs, or a genetic disorder; but in many cases the cause is unknown.

The acidosis may result in osteomalacia, kidney stones (see calculus, urinary tract), nephrocalcinosis, and hypokalaemia (an abnormally low level of potassium in the blood).... renal tubular acidosis

Retinal Artery Occlusion

Blockage of an artery supplying blood to the retina, most commonly due to thrombosis or embolism, The disorder can result in permanent blindness or loss of part of the field of vision, depending on the artery affected and whether or not the condition can be treated quickly enough.... retinal artery occlusion

Retinal Detachment

Separation of the retina from the outer layers at the back of the eye. Detachment may follow an eye injury but usually occurs spontaneously. It is usually preceded by a retinal tear, and is more common in highly myopic (shortsighted) people and in people who have had cataract surgery.

The detachment is painless. The first symptom is either bright flashes of light at the edge of the field of vision, accompanied by floaters, or a black “drape” obscuring vision.

Urgent treatment is required and usually involves surgical repair of the underlying tear. If the macula (site of central vision) has not been detached, the results can be excellent.... retinal detachment

Retinal Vein Occlusion

Blockage of a vein carrying blood away from the retina.

It usually results from thrombosis in the affected vein, and is more common in people who have glaucoma.

Retinal vein occlusion may cause visual disturbances, glaucoma, or blindness.... retinal vein occlusion

Retinitis Pigmentosa

An inherited condition in which there is degeneration of the rods and cones of the retina at the back of both eyes.

The 1st symptoms appear during or after adolescence and include night blindness.

Tests show a ring-shaped area of blindness which, over some years, extends to destroy an increasing area of the visual field, though central vision is retained, often for many years.

Opthalmoscopy reveals several masses of black pigment corresponding to the areas of visual loss.

Affected individuals and their parents should have genetic counselling.... retinitis pigmentosa

Retrolental Fibroplasia

Also called retinopathy of prematurity, a condition that mainly affects the eyes of premature infants. The usual cause is high concentrations of oxygen being given as part of the treatment for respiratory distress. Excess oxygen causes the tissues at the margin of the retina to shut down their blood vessels. When oxygen concentrations return to normal, the affected tissues may send strands of new vessels and fibrous scar tissue into the vitreous humour. This may interfere with vision and cause retinal detachment. Laser treatment may be used.... retrolental fibroplasia

Rett’s Syndrome

A brain disorder, thought to be a genetic disorder, that only affects girls. Symptoms usually occur when the child is 12–18 months old. Acquired skills, such as walking and communication skills, disappear and the girl becomes progressively handicapped, perhaps with signs of autism. There are repetitive writhing movements of the hands and limbs, and inappropriate outbursts of crying or laughter. There is no cure for Rett’s syndrome and sufferers need constant care and attention. Parents of an affected child should receive genetic counselling.... rett’s syndrome

Reye’s Syndrome

A rare disorder in which brain and liver damage follow a viral infection. Children over 15 are rarely affected. The cause is unknown, but aspirin seems to be a predisposing factor to developing the condition and is therefore not recommended for children.

The disorder starts as the child recovers from the infection. Symptoms include uncontrollable vomiting, lethargy, memory loss, and disorientation. Swelling of the brain may cause seizures, disturbances in heart rhythm, coma, and cessation of breathing.

Brain swelling may be controlled by corticosteroid drugs and by intravenous infusions of mannitol. Dialysis or blood transfusions may be needed. If breathing stops, a ventilator is used.

The death rate is around 10 per cent, and higher for those who have seizures, lapse into deep coma, and stop breathing.

Rhabdomyolysis

Destruction of muscle tissue accompanied by the release of myoglobin into the blood. The commonest cause is a severe, crushing muscle injury (see crush syndrome). Other causes include polymyositis and, rarely, excessive exercise. There is usually temporary paralysis or weakness of the affected muscle. Except in cases of severe injury, the condition clears up without treatment.... rhabdomyolysis

Rhabdomyosarcoma

Rigor Mortis

The stiffening of muscles that starts 3–4 hours after death.

It is usually complete after about 12 hours; the stiffness then disappears over the next 48–60 hours.

Physical exertion before death makes rigor mortis begin sooner.

The sooner rigor mortis begins, the quicker it passes.

These facts are used to help assess the time of death.... rigor mortis

Root-canal Treatment

A dental procedure performed to save a tooth in which the pulp (see pulp, dental) has died or become untreatably diseased, usually as the result of extensive dental caries.

The pulp is removed through a hole drilled in the crown. An antibiotic paste and a temporary filling are packed in. A few days later, the filling is removed and the canals are checked for infection. When no infection is detected the cavity is filled and the roots are sealed with cement. If the cavity is not filled completely, periodontitis may occur.

Treated teeth may turn grey but their appearance can be restored by bonding (see bonding, dental), fitting an artificial crown (see crown, dental), or by bleaching (see bleaching, dental).... root-canal treatment

Acute Respiratory Distress Syndrome (ards)

Formerly known as adult respiratory distress syndrome. A form of acute respiratory failure in which a variety of di?erent disorders give rise to lung injury by what is thought to be a common pathway. The condition has a high mortality rate (about 70 per cent); it is a complex clinical problem in which a disproportionate immunological response plays a major role. (See IMMUNITY.)

The exact trigger is unknown, but it is thought that, whatever the stimulus, chemical mediators produced by cells of the immune system or elsewhere in the body spread and sustain an in?ammatory reaction. Cascade mechanisms with multiple interactions are provoked. CYTOTOXIC substances (which damage or kill cells) such as oxygen-free radicals and PROTEASE damage the alveolar capillary membranes (see ALVEOLUS). Once this happens, protein-rich ?uid leaks into the alveoli and interstitial spaces. SURFACTANT is also lost. This impairs the exchange of oxygen and carbon dioxide in the lungs and gives rise to the clinical and pathological picture of acute respiratory failure.

The typical patient with ARDS has rapidly worsening hypoxaemia (lack of oxygen in the blood), often requiring mechanical ventilation. There are all the signs of respiratory failure (see TACHYPNOEA; TACHYCARDIA; CYANOSIS), although the chest may be clear apart from a few crackles. Radiographs show bilateral, patchy, peripheral shadowing. Blood gases will show a low PaO2 (concentration of oxygen in arterial blood) and usually a high PaCO2 (concentration of carbon dioxide in arterial blood). The lungs are ‘sti?’ – they are less e?ective because of the loss of surfactant and the PULMONARY OEDEMA.

Causes The causes of ARDS may be broadly divided into the following:... acute respiratory distress syndrome (ards)

Adrenergic Receptors

The sites in the body on which ADRENALINE and comparable stimulants of the SYMPATHETIC NERVOUS SYSTEM act. Drugs which have an adrenaline-like action are described as being adrenergic. There are ?ve di?erent types of adrenergic receptors, known as alpha1, alpha2, beta1, beta2 and beta3 respectively. Stimulation of alpha receptors leads to constriction of the bronchi, constriction of the blood vessels with consequent rise in blood pressure, and dilatation of the pupils of the eyes. Stimulation of beta1 receptors quickens the rate and output of the heart, while stimulation of beta2 receptors dilates the bronchi. Beta3 receptors are now known to mediate so-called non-shivering thermogenesis, a way of producing heat from specialised fat cells that is particularly relevant to the human infant.

For long it had been realised that in certain cases of ASTHMA, adrenaline had not the usual bene?cial e?ect of dilating the bronchi during an attack; rather it made the asthma worse. This was due to its acting on both the alpha and beta adrenergic receptors. A derivative, isoprenaline, was therefore produced which acted only on the beta receptors. This had an excellent e?ect in dilating the bronchi, but unfortunately also affected the heart, speeding it up and increasing its output – an undesirable e?ect which meant that isoprenaline had to be used with great care. In due course drugs were produced, such as salbutamol, which act predominantly on the beta2 adrenergic receptors in the bronchi and have relatively little e?ect on the heart.

The converse of this story was the search for what became known as BETA-ADRENOCEPTORBLOCKING DRUGS, or beta-adrenergic-blocking drugs. The theoretical argument was that if such drugs could be synthesised, they could be of value in taking the strain o? the heart – for example: stress ? stimulation of the output of adrenaline ? stimulation of the heart ? increased work for the heart. A drug that could prevent this train of events would be of value, for example in the treatment of ANGINA PECTORIS. Now there is a series of beta-adrenoceptor-blocking drugs of use not only in angina pectoris, but also in various other heart conditions such as disorders of rhythm, as well as high blood pressure. They are also proving valuable in the treatment of anxiety states by preventing disturbing features such as palpitations. Some are useful in the treatment of migraine.... adrenergic receptors

Adverse Reactions To Drugs

When a new drug is introduced, it has usually been studied only in relatively few patients – typically 1,500. If n patients have been studied, and no serious effects observed, there is still a chance of a serious adverse e?ect occurring in the general population as frequently as 3/n (1:500).

Adverse effects can be divided into types. First, those which are closely related to the concentration of the drug and accord with what is known of its PHARMACOLOGY. These so-called type A (augmented pharmacological) effects are distinguished from type B (bizarre) effects which are unpredictable, usually rare, and often severe. ANAPHYLAXIS is the most obvious of these; other examples include bone-marrow suppression with CO-TRIMOXAZOLE; hepatic failure (see HEPATITIS) with SODIUM VALPROATE; and PULMONARY FIBROSIS with AMIODARONE. A more comprehensive classi?cation includes reactions type C (chronic effects), D (delayed effects – such as teratogenesis or carcinogenesis) and E (end-of-dose effects – withdrawal effects). Examples of adverse reactions include nausea, skin eruptions, jaundice, sleepiness and headaches.

While most reported adverse reactions are minor and require no treatment, patients should remind their doctors of any drug allergy or adverse e?ect they have suffered in the past. Medical warning bracelets are easily obtained. Doctors should report adverse effects to the authorities – in the case of Britain, to the Committee on Safety of Medicines (CSM), using the yellow-card reporting machinery.... adverse reactions to drugs

Along with other therapeutic applications, The Ayurvedic Pharmacopoeia of India indicates the use of the tuberous root in gout, puerperal diseases, lactic disorders, haematuria, bleeding disorders and also recommends it for hyperacidity.

The plant contains saponins—sha- tavarins I-IV. Shatavarin IV is a glycoside of sarsasapogenin. The saponin in doses of 20-500 mcg/ml produces a special blockade of syntocinon (oxy- tocin)-induced contraction of rat, guinea-pig and rabbit uteri in vitro and in situ. It also blocks the uterine spontaneous motility.

The dried root yields sitosterol; 4,6- dihydroxy-2-O-(2' hydroxyisobutyl) benzaldehyde and undecanyl cetano- ate, and contains a large amount of saccharine matter, mucilage and miner- als—Ca (0.172), Cu (0.033), Na (14.60), K (8.32), Mg (0.169), Mn (0.0074), Ni (0.105) and Zn (0.072) mg/g(dry weight).

The herb contains tropane (tropine) or solanaceous alkaloids (up to 0.6%), including hyoscamine and atropine; flavonoids; coumarins; volatile bases (nicotine).

Tropane alkaloids inhibit the para- sympathetic nervous system, which controls involuntary bodily activities; reduces saliva, gastric, intestinal and bronchial secretions, and also the activity of urinary tubules. Tropane alkaloids also increase the heart rate and dilate the pupils. These alkaloids are used as an additive to compound formulations for bronchitis, asthma, whooping cough, gastrointestinal hy- permotility, dysmenorrhoea, nocturnal enuresis and fatigue syndrome.

Atropine provides relief in parkin- sonism and neurovegetative dystonia.

The root is the most poisonous, the leaves and flowers less, and the berries the least. (Francis Brinker.)

Cardiopulmonary Resuscitation (cpr)

The use of life-saving measures of mouth-tomouth resuscitation and external cardiac compression massage in a person who has collapsed with CARDIAC ARREST. Speedy restoration of the circulation of oxygenated blood to the brain is essential to prevent damage to brain tissues from oxygen starvation. The brain is irreversibly damaged if it is starved of oxygen for more than 4–5 minutes. Someone whose heart has stopped will be very pale or blue-grey (in particular, round the lips) and unresponsive; he or she will not be breathing and will have no pulse. It is important to determine that the collapsed person has not simply fainted before starting CPR. The procedure is described under car-diac/respiratory arrest in APPENDIX 1: BASIC FIRST AID. In hospital, or when paramedical sta? are attending an emergency, CPR may include the use of a DEFIBRILLATOR to apply a controlled electric shock to the heart via the chest wall.... cardiopulmonary resuscitation (cpr)

Concurrent Review

Cause-of-death Ranking

Cause-of-death ranking for adults is based on the List of 72 Selected Causes of Death, HIV Infection, and Alzheimer’s Disease. The List was adapted from one of the special lists for mortality tabulations recommended for use with the International Classification of Diseases, ninth revision. Two group titles – “Major cardiovascular diseases” and “Symptoms, signs, and ill-defined conditions” – are not ranked based on the list of 72 selected causes. In addition, category titles that begin with the words “other” and “all other” are not ranked. The remaining category titles are ranked according to number of deaths to determine the leading causes of death. When one of the titles that represents a subtotal is ranked (for example, unintentional injuries), its component parts are not ranked (in this case, motor vehicle crashes and all other unintentional injuries).... cause-of-death ranking

Cimicifuga Racemosa

(Linn.) Nutt.

Family: Ranunculaceae.

Habitat: Temperate Himalayas from Kashmir to Bhutan up to at 3,000-4,000 m.

English: Black Cohosh Root, Black Snake Root.

Folk: Cohosh, Jiuenti (Punjab).

Action: Sedative, anti-inflammatory, antitussive, diuretic, emmenagogue. Used in homoeopathy for rheumatic diseases of nervous, hysterical women, suffering from uterine affections; also for locomotor ataxia.

Key application: In climacteric (menopausal), neurovegetative ailments, premenstrual discomfort and dysmenorrhoea. (German Commission E, ESCOP.)

The rhizome contains triterpene gly- cosides (including actein, cimigoside, cimifugine and racemoside; isofla- ones (including formononetin; isofer- ulic acid; volatile oil, tannin.

Pharmacological studies have shown that the menthol extract binds to oestrogen receptors in vitro and in rat uteri; this activity is thought to be due to the presence of formononetin. Racemoside exhibited antiulcer activity in mice. Isoferulic acid lowered body temperature in rats.

The rhizome is hypotensive in animals; a central nervous system depressant and antispasmodic in mice; causes peripheral vasodilation in human. Also exhibits anti-inflammatory (The British Herbal Pharmacopoeia) and hy- poglycaemic activity.

Actein has been studied for use in treating peripheral arterial disease. (Expanded Commission E Monographs.)

Clinically, the rhizome and root constituents of Black Cohosh does not seem to affect hormonal levels, such as estradiol, LH, FSH and pro- lactin. (Natural Medicines Comprehensive Database, 2007.)

Cimicifuga foetida L. root is used in bronchial and rheumatic diseases. Aqueous EtOH extract is used in cosmetic preparations for protecting skin; also used for preventing oral diseases and bad breath.

Clinical Risk Management

Initially driven by anxiety about the possibility of medical negligence cases, clinical risk management has evolved into the study of IATROGENIC DISEASE. The ?rst priority of risk managers is to ensure that all therapies in medicine are as safe as possible. Allied to this is a recognition that errors may occur even when error-prevention strategies are in place. Lastly, any accidents that occur are analysed, allowing a broader understanding of their cause. Risk management is generally centred on single adverse events.

Action: Carminative, astringent, anti-inflammatory, antirheumat- ic, hepatoprotective, diuretic, antipyretic, analgesic, hypoten- sive, emmenagogue and nervine tonic.

Used for intestinal problems, indigestion, sprue, diarrhoea, dysentery, vomiting and fever; also as a hypoc- holesterolaemic drug and in obesity.

Along with other therapeutic applications, The Ayurvedic Pharmacopoeia of India indicated the use of the rhizome in rheumatism, inflammations, dysuria, puerperal diseases and obesity.

The tuber is rich in Cu, Fe, Mg and Ni. Beta-sitosterol, isolated from the tubers, exhibits significant anti- inflammatory activity against carra- geenan- and cotton pellet-induced oedema in rats; the activity is comparable to hydrocortisone and phenylbutazone when administered intraperi- toneally.

The alcoholic and aqueous extracts of the tubers possess lipolytic action and reduce obesity by releasing enhanced concentrations of biogenic amines from nerve terminals of the brain which suppress the appetite centre. Presence of eudalne group of ses- quiterpenic compounds of sesquiter- pene alcohol, isocyperol is said to play an important role in lipid metabolism.

An alcoholic extract of the plant exhibits liver-protective activity against CCL4-induced liver damage in mice.

Methanolic extract of the plant stimulates the production of melanin in cultured melanocytes. (Plant extract is used in preparations used for pigmentation of skin and hair, also in suntan gels.) Aqueous-alcoholic extract of the tuber exhibited hypotensive, diuretic, antipyretic and analgesic activities. These are attributed to a triterpenoid.

The essential oil (0.5-0.9%) from the tubers contains mainly sesquiterpenes.

Embryo Research

When a woman is treated for infertility it is necessary to nurture human embryos for a few days (until the ?rst cell divisions of the fertilised egg have occurred) in a specialised laboratory. More eggs are fertilised than are usually needed because not all fertilisations are successful. Surplus embryos may be frozen for use in later attempts to implant an embryo in the womb. Research has been done on very early embryos but the practice is controversial and some countries have either forbidden it or imposed tight restrictions. In the UK such research is controlled by the government Human Fertilisation & Embryology Authority (see ASSISTED CONCEPTION).... embryo research

Ayurvedic: Udumbara, Sadaaphala, Hema-daudhaka, Jantuphala, Yagyaanga.

Unani: Anjir-e-Aadam, Anjir-e- Ahmak, Gular.

Siddha/Tamil: Atthi.

Action: Astringent and antiseptic; used in threatened abortions, menorrhagia, leucorrhoea, urinary disorders, skin diseases, swellings, boils, haemorrhages. Unripe fruits—astringent, carminative, digestive, stomachic; used in diarrhoea, dyspepsia, dysentery, menorrhagia and haemorrhages. Ripe fruits—antiemetic, also

used in haemoptysis. Root and fruit—hypoglycaemic. Bark— decoction is used in skin diseases, inflammations, boils and ulcers.

The Ayurvedic Pharmacopoeia of India recommends the use of the bark in lipid disorders and obesity.

Leaves and fruit contain gluacol. The fruit also contains beta-sitosterol, lupeol acetate, friedelin, higher hydrocarbons and other phytosterols.

Petroleum ether extract of the stem bark significantly reduced blood sugar level of rats with streptozotocin- induced diabetes. It completely inhibited glucose-6-phosphate dehydrogenase from rat liver. Extracts of fruit and latex did not show any significant effect on blood sugar level of diabetic rats, they inhibited only glucose-6- phosphate but not arginase from rat liver.

An alcoholic extract of the bark has been found to be very effective in reducing blood sugar in alloxan-induced diabetic albino rats. It helped in improving the damaged beta cells of islets of Langerhans, thus exerting permanent blood sugar lowering effect.

The ethanolic extract of seeds also showed hypoglycaemic activity.

Lignin, the main fiber constituent of the fruit, prevented the rise in serum cholesterol levels of some extent. Fresh whole fruits, used as a source of dietary fibre, exhibited more hypoc- holesterolemic activity than pure cellulose.

Gastro-oesophageal Reflux

A disorder in which the contents of the STOMACH back up into the OESOPHAGUS because the usual neuromuscular mechanisms for preventing this are intermittently or permanently failing to work properly. If persistent, the failure may cause oesophagitis (see OESOPHAGUS, DISEASES OF). If a person develops HEARTBURN, regurgitation, discomfort and oesophagitis, the condition is called gastro-oesophageal re?ux disease (GORD) and sometimes symptoms are so serious as to warrant surgery. Gastrooesophageal re?ux is sometimes associated with HIATUS HERNIA.

Gastro-oesophageal disease should be diagnosed in those patients who are at risk of physical complications from the re?ux. Diagnosis is usually based on the symptoms present or by monitoring the production of acid using a pH probe inserted into the oesophagus through the mouth, since lesions are not usually visible on ENDOSCOPY. Severe heartburn, caused by the lining of the oesophagus being damaged by acid and PEPSIN from the stomach, is commonly confused with DYSPEPSIA. Treatment should start with graded doses of one of the PROTON PUMP INHIBITORS; if this is not e?ective after several months, surgery to remedy the re?ux may be required, but the effects are not easily predictable.... gastro-oesophageal reflux

Glomerular Filtration Rate (gfr)

Each of the two KIDNEYS ?lters a large volume of blood – 25 per cent of cardiac output, or around 1,300 ml – through its two million glomeruli (see GLOMERULUS) every minute. The glomeruli ?lter out cell, protein, and fat-free ?uid which, after reabsorption of certain chemicals, is excreted as urine. The rate of this ultra?ltration process, which in health is remarkably constant, is called the glomerular ?ltration rate (GFR). Each day nearly 180 litres of water plus some small molecular-weight constituents of blood are ?ltrated. The GFR is thus an indicator of kidney function. The most widely used measurement is CREATININE clearance and this is assessed by measuring the amount of creatinine in a 24-hour sample of urine and the amount of creatinine in the plasma; a formula is applied that gives the GFR.... glomerular filtration rate (gfr)

Gravel Root Tea

Gravel Root Tea is known for its diuretic, astringent and anti-inflammatory properties. Gravel root (eupatorium purpureum) is a perennial plant that can grow up to 5 feet tall, having pointed oblong leaves and small pink flowers. It grows in North America, from southern Canada through Florida. The main constituents of gravel root are tannins, flavonoids and bitter principles. How To Make Gravel Root Tea To brew Gravel Root Tea, you will need to boil 1 teaspoon of gravel root in a cup of water. Let the mix stand for about 10 minutes. Optionally you can add sugar or honey, depending on your preferences. Gravel root tea can be drank 3 times a day! Gravel Root Tea Benefits
  • Helps prevent the formation of kidney and bladder stones.
  • Effective in treating gout.
  • Relieves fever by encouraging sweating.
  • Treats various urinary problems.
  • Helps relieve constipation.
  • Reduces stomach acidity.
  • In some cases, it can act as an anti-inflammatory, reducing swelling.
Gravel Root Tea Side Effects
  • Due to the fact that Gravel Root Tea contains chemicals called hepatotoxic pyrrolizidine alkaloids (PAs), it may block blood flow and cause liver damage.
  • Pregnant women should avoid drinking Gravel Root Tea since it can produce birth defects. Also, if you are breastfeeding, do not drink gravel root tea, because the chemicals (PAs) can affect the breast-milk and harm the baby.
  • Do not apply gravel root on wounds or broken skin. The chemicals can be absorbed quickly through broken skin and can lead to dangerous body-wide toxicity.

Infant Mortality Rate (imr)

The number of deaths of infants under one year of age. The IMR in any given year is calculated as the number of deaths in the ?rst year of life in proportion to every 1,000 registered live births in that year. Along with PERINATAL MORTALITY, it is accepted as one of the most important criteria for assessing the health of the community and the standard of the social conditions of a country.

The improvement in the infant mortality rate has occurred mainly in the period from the second month of life. There has been much less improvement in the neonatal mortality rate – that is, the number of infants dying during the ?rst four weeks of life, expressed as a proportion of every 1,000 live births. During the ?rst week of life the main causes of death are asphyxia, prematurity, birth injuries and congenital abnormalities. After the ?rst week the main cause of death is infection.

Social conditions also play an important role in infant mortality. In England and Wales the infant mortality rate in 1930–32 was: Social Class I (professional), 32·7; Social Class III (skilled workers), 57·6; Social Class V (unskilled workers), 77·1. Many factors come into play in producing these social variations, but overcrowding is undoubtedly one of the most important.

1838–9 146 1950–52 30 1851–60 154 1960–62 22 1900–02 142 1970–72 18 1910–12 110 1980–82 12 1920–22 82 1990–92 7 1930–32 67 1996 6·2 1940–42 59 1999 5.8 2000 5.6

It is thus evident that for a reduction of the infant mortality rate to the minimum ?gure, the following conditions must be met. Mothers and potential mothers must be housed adequately in healthy surroundings, particularly with regard to safe water supplies and sewage disposal. The pregnant and nursing mother must be ensured an adequate diet. E?ective antenatal supervision must be available to every mother, as well as skilled supervision during labour (see PREGNANCY AND LABOUR). The newborn infant must be adequately nursed and fed and mothers encouraged to breast feed. Environmental and public-health measures must be taken to ensure adequate housing, a clean milk supply and full availability of medical care including such protective measures as IMMUNISATION against diphtheria, measles, poliomyelitis and whooping-cough.

Lipid-regulating Drugs

These drugs reduce the amount of low-density LIPOPROTEINS, which transport CHOLESTEROL and triglycerides (see TRIGLYCERIDE) in the blood, or raise the concentration of high-density lipoproteins. The aim is to reduce the progression of ATHEROSCLEROSIS and therefore help prevent coronary heart disease (see HEART, DISEASES OF). These drugs should be combined with reducing other risk factors for raised lipid concentrations, such as a high-fat diet, smoking and obesity. Lipid-regulating drugs include STATINS, ?brates, anion-exchange resins, and NICOTINIC ACID, which may be used singly or in combination under careful medical supervision (see HYPERLIPIDAEMIA).... lipid-regulating drugs

Insulin-resistant Diabetes

Also called NIDDM (Non-Insulin-Dependent Diabetes) and Type II (Type II), it generally means you make your own insulin, you eat too many calories, your storage cells are filled and are taking no more fuel, your liver is stuck in a rut and keeps making more glucose out of everything you eat, your brain has no control over its consumption of glucose, but you have run out of places to put it so you pee it out, sweat it out, etc. etc. Also called Adult-onset Diabetes. An Internist may cry out in dismay at this simplification, and there are many subtle distinctions between the various types, as well as a number of distinct hereditary considerations. This, however, is the glossary of an herbalist, and this is the common picture of the Type II person that herbs will help.... insulin-resistant diabetes

Inula Racemosa

Methicillin-resistant Staphylococcus Aureus (mrsa)

Most staphylococci (see STAPHYLOCOCCUS) have now evolved resistance to benzylpenicillin (see PENICILLIN) because of their ability to produce PENICILLINASE. Cloxacillin and ?ucloxacillin are antibiotics still e?ective against most staphylococci; at one time methicillin was used to combat resistant strains, but in hospital environments bacteria acquired immunity to this powerful drug (now withdrawn from use) and to cloxacillin. RIFAMPICIN, VANCOMYCIN, TEICOPLANIN and temocillin are still active against most penicillinase-producing gram-negative bacteria (see GRAM’S STAIN). There is, however, a growing threat to health because of the rise in the number of antibiotic-resistant bacteria, particularly in hospitals. The bacteria themselves are not more virulent than others, but the di?culty in treating them with a safe and e?ective antibiotic mean that they are more dangerous. It is likely that lapses in normal hygienic practice – such as frequent hand-washing – has resulted in an increase in MRSA disease.... methicillin-resistant staphylococcus aureus (mrsa)

Muscle Relaxants

These drugs produce partial or complete paralysis of skeletal muscle (see under MUSCLE – Structure of muscle). Drugs in clinical use are all reversible and are used to help insert a breathing tube into the TRACHEA (endotracheal tube) during general ANAESTHESIA and ARTIFICIAL VENTILATION OF THE LUNGS. They may be broadly divided into depolarising and nondepolarising muscle relaxants. Depolarising muscle relaxants act by binding to acetylcholine receptors at the motor end-plate where nerves are attached to muscle cells, and producing a more prolonged depolarisation than acetylcholine, which results in initial muscle fasciculation (overactivity) and then ?accid paralysis of the muscle. The only commonly used depolarising drug is succinylcholine which has a rapid onset of action and lasts approximately three minutes. Non-depolarising muscle relaxants bind to the acetylcholine receptors, preventing acetylcholine from gaining access to them. They have a slower onset time and longer duration than depolarisers, although this varies widely between di?erent drugs. They are competitive antagonists and they may be reversed by increasing the concentration of acetylcholine at the motor end-plate using an anticholinesterase agent such as neostigmine. These drugs are broken down in the liver and excreted through the kidney, and their action will be prolonged in liver and renal failure. Other uses include the relief of skeletal muscle spasms in TETANUS, PARKINSONISM and spastic disorders. The drugs dantrolene and diazepam are used in these circumstances.... muscle relaxants

Randia Dumetorum

Poir.

Synonym: R. spinosa Poir. R. brandisii Gamble. R. longispina W. & A. R. tomentosa W. & A. non Blume. Xeromphis spinosa Keay.

Habitat: Assam, Naga and Khasi Hills, Travancore and the Andamans.

English: Common Emetic Nut.

Ayurvedic: Madana, Chhardana, Pindi, Shalayaka, Vishapushpaka.

Unani: Mainphal, Jauz-ul-Qai.

Siddha/Tamil: Marukkaaraikai, Madkarai.

Folk: Mainphal.

Action: Fruit—nervine, calmative, antispasmodic, emetic, anthelmintic, abortifacient. Used as a substitute for ipecacuanha.

The Ayurvedic Pharmacopoeia ofIn- dia recommends the dried fruit in chlorosis, common cold, rhinitis and obstinate skin diseases.

The activity of the drug is attributed to the presence of saponins which occur to the extent of 2-3% in fresh fruits and about 10% in dried whole fruit. The saponins are concentrated mostly in the pulp. A mixture of two saponins, viz. randialic or neutral saponin and randialic acid or acid saponin has been isolated from the pulp. On complete hydrolysis both the saponins yield oleanolic acid as sapogenin. Ursosaponin, isolated from the ethanolic extract of the dried whole fruit, gave ursolic acid and glucose. Randianin, isolated from the fruit, gave a haemolytic triterpe- noid saponin.

In experimental animals, the drug caused haemolysis both in vitro and in vivo. Crude saponin fraction showed haemolytic, molluscidal and immuno- stimulating activities.

Oleanolic acid 3-glucoside, isolated from the seed, exhibited anti-arthritic activity in exudative and proliferative phases of inflammation in rats.

Dosage: Fruit—0.5-1.0 g powder for decoction, 3-6 g for induction vomiting. (API, Vol. I.)... randia dumetorum

Randia Uliginosa

DC.

Synonym: Catunaregam uliginosa (Retz.) Sivarajan.

Ayurvedic: Pindaalu, Pinditaka.

Siddha/Tamil: Wagatta, Perunkarai.

Folk: Mainphal, Pindaar, Pendraa, Pendhar.

Action: Unripe fruit—astringent. Root—diuretic; used for biliousness, diarrhoea and dysentery

Unripe fruits are roasted and used as a remedy for dysentery and diarrhoea. The root, boiled in purified butter, is also prescribed for dysentery and diarrhoea.

The fruits, like those of Randia spinosa, contain a toxic saponin of oleanolic acid. They also contain leu- cocyanidin and mannitol. The flowers yield an essential oil similar to Gardenia oil.... randia uliginosa

Random Variation / Random Error

The tendency for the estimated magnitude of a parameter (e.g. based upon the average of a sample of observations of a treatment or intervention effect) to deviate randomly from the true magnitude of that parameter. Random variation is independent of the effects of systematic biases. In general, the larger the sample size, the lower the random variation of the estimate of a parameter. As random variation decreases, precision increases.... random variation / random error

Randomised Controlled Trial

A method of comparing the results between two or more groups of patients intentionally subjected to di?erent methods of treatment – or sometimes of prevention. Those subjects entering the trial have to give their informed permission. They are allocated to their respective groups using random numbers, with one group (controls) receiving no active treatment, instead receiving either PLACEBO or a traditional treatment. Preferably, neither the subject nor the assessor should know which ‘regimen’ is allocated to which subject: this is known as a double-blind trial.... randomised controlled trial

Raphanus Sativus

Linn.

Family: Cruciferae; Brassicaceae.

Habitat: Cultivated in Uttar Pradesh, Punjab, Maharashtra and Gujarat.

English: Radish.

Ayurvedic: Muulaka, Laghu- muulaka, Muulakapotikaa, Visra, Shaaleya, Marusambhava. Pods— Sungraa, Singri, Mungraa.

Unani: Muuli, Turb Fajal.

Siddha/Tamil: Mullangi.

Action: Radish—preparations are used in liver, gallbladder and urinary complaints. Green leaves— diuretic and carminative. Seeds— diuretic, purgative, expectorant.

A decoction of dry radish is given orally in piles. Extract of the dry root is given for hiccough, influenza, dysentery, colic and urinary troubles.

Key application: In peptic disorders, especially those related to dyskinesia of the bile ducts; and in catarrhs of the upper respiratory tract. (German Commission E.)

The Ayurvedic Pharmacopoeia of India recommends the juice of the whole plant in sinusitis; juice of the root in diseases of the throat and sinusitis; and the seed in amenorrhoea, cough and dyspnoea.

The fleshy root and seeds contain trans-4-methyl-thiobutenyl isothio- cyanate glucoside (the pungent principle), cyanidin-5-glucoside-3-sophoro- side, pelargonidin diglycoside, cyani- din diglycoside, 5-methyl-L-cysteine- sulphoxide (methiin), steroidal sa- pogenins and sulphorophene.

The enzymes present in the radish are phosphatase, catalase, sucrase, amylase, alcohol dehydrogenase and pyruvic carboxylase.

Radish contains caffeic acid and fer- ulic acid which exhibit hepatoprotec- tive and choleretic properties. It contains choline which prevents deposition of fat in liver. Amino acids, or- nithine, citrulline, arginine, glutamic acid and asparatic acid remove toxins from the body and urea acumulation.

Radish is a good source of ascorbic acid (15-40 mg/100 g), trace elements include aluminium, barium, lithium, manganese, silicon, titanium, also iodine (upto 18 mcg/100 g) and ascor- bigen.

Roots, leaves, flowers and pods are active against Gram-positive bacteria.

The seeds are reported to contain a broad spectrum antibiotic, machro- lysin, specific against Mycobacterium tuberculosis. Raphanin, extracted from the seeds, is active against Grampositive and Gram-negative bacteria.

A purified basic protein, homologous to nonspecific lipid transfer proteins, from seeds showed antifungal activity.

Raphanus caudatus Linn., synonym R. sativus var. caudatus, is known as Rat-Tail Radish.

A native to Java, it is cultivated in northern and western India. The root is not used; pods, purple or violet in colour, are consumed for properties attributed to Raphanus sp. These are known as Mungraa or Sungraa.

Dosage: Whole plant-20-40 ml juice; root—15-30 ml juice. (API, Vol. II.) Seed—1-3 g powder. (API, Vol. III.)... raphanus sativus

Rapid-eye-movement (rem) Sleep

This is characterised by the presence of rapid eye movements and a reduction in muscle tone. Cerebral cortical activity is prominent and its blood ?ow increased. This activity is, however, di?erent from wakefulness and may cause irregular movements of the body as well as of the eyes. Most dreams occur in REM sleep: these may represent a process of reorganising mental associations after the period of wakefulness. The analysis of the content of dreams has been subject to a variety of interpretations, but no consensus view has evolved.

Physiological changes, such as a fall in temperature and blood pressure, take place just before sleep and continue during the early stages of NREM sleep. There is an intrinsic rhythm of sleep which in most subjects has a periodicity of around 25 hours. This can be modi?ed by external factors to bring it into line with the 24-hour day. Two peaks of a tendency to sleep have been identi?ed, and these usually occur between around 14.00–18.00 hours, and 02.00–06.00 hours. There are, however, di?erences according to age, in that, for instance, infants sleep for most of the 24 hours; during adolescence there is also an increase in the duration of sleep. Sleep requirements fall later in life, but there are wide genetic di?erences in the amount of sleep that people require and also the time at which they fall asleep most readily.

The internal clock can be disturbed by a variety of external factors which include irregular sleeping habits due, for instance, to shift work or jet lag. Sleep is also more likely to occur after physical exertion, reading and social activity. The duration and intensity of exposure to light can also modify sleep profoundly. Light promotes wakefulness and is the main factor that adjusts the 25-hour internal rhythm to the 24hour daily cycle. Neural connections from the retina of the EYE act on an area in the brain called the supra-chiasmatic nucleus which stimulates the pineal gland which produces MELATONIN. This is thought to trigger the range of neurological and metabolic processes that characterise sleep.... rapid-eye-movement (rem) sleep

Rattan Palm

Calamus species

Description: The rattan palm is a stout, robust climber. It has hooks on the midrib of its leaves that it uses to remain attached to trees on which it grows. Sometimes, mature stems grow to 90 meters. It has alternate, compound leaves and a whitish flower.

Habitat and Distribution: The rattan palm is found from tropical Africa through Asia to the East Indies and Australia. It grows mainly in rain forests.

Edible Parts: Rattan palms hold a considerable amount of starch in their young stem tips. You can eat them roasted or raw. In other kinds, a gelatinous pulp, either sweet or sour, surrounds the seeds. You can suck out this pulp. The palm heart is also edible raw or cooked.

Other Uses: You can obtain large amounts of potable water by cutting the ends of the long stems (see Chapter 6). The stems can be used to make baskets and fish traps.... rattan palm

Rauvolfia Tetraphylla

Linn.

Synonym: R. canescens L.

Family: Apocynaceae.

Habitat: Abundant in moist and warm regions of West Bengal, particularly in 24 Parganas and Howrah, and Kerala (as a weed).

Folk: Badaa Chaand.

Action: Root—sedative, hypotensive. Plant juice, mixed with castor oil, is applied to skin diseases and to destroy parasites.

The plant contains a number of alkaloids, including rauvolscine, aj- malicine, canescine, reserpine, pseu- doyohimbine; yohimbine, corynan- thene, raunescine, iso-raunescine and recanescine.

The major alkaloid is rauwolscine (alpha-yohimbine), present in the root bark (0.1%), stem bark (0.2%) and leaves (0.5%).

The roots are often used as a substitute or adulterant of those of R. serpentina, though the reserpine content of the dried root was found to be comparatively low (0.03-0.05%).

Family: Linaceae.

Habitat: The Himalayas from Kashmir to Sikkim; commonly grown in gardens.

English: Winter-Flax, Yellow Flax.

Ayurvedic: Baasanti.

Folk: Abai (Maharashtra).

Rauvolfia Serpentina

Benth. ex Kurz.

Family: Apocynaceae.

Habitat: The sub-Himalayas tract from Punjab to Nepal, Sikkim, Bhutan, Assam, Western Ghats and the Andamans.

English: Rauvolfia root, Serpentina Root, Indian Snakeroot.

Ayurvedic: Sarpagandhaa of Ayurvedic texts was not the Sarpagandhaa of modern medicine. (Sarpagandhaa was equated with Naakuli, Sarpach- hatrikaa and Varshaasu Chha- trikaaraa. Sarpagandhaa and Sarpasugandhaa were synonyms of Naakuli.)

Folk: Chhotaa Chaand.

Action: Root—decoction is employed to increase uterine contractions and for expulsion of foetus in difficult cases. The total alkaloidal extract of the root induces bradycardia, hypotension, sedation. It finds application in hypochondria, neuropsychi- atric disorders, psychosis and schizophrenia.

Key application: In mild, essential hypertension (borderline hypertension, especially with elevated tension of the sympathetic nervous system, for example, sinus tachycardia, anxiety, tension and psychomotor irritation, when dietetic measures alone are not sufficient. (German Commission E.)

(Average daily dose: 600 mg drug corresponding to 6 mg total alkaloid.) Treatment is usually administered with a diuretic to prevent fluid retention which may develop if Rauvolfia root is given alone. (WHO.) Contraindicated in depression, bleeding disorders, gastric and duodenal ulcers. (Sharon M. Herr.) Also contraindicated in pregnancy, since it has both teratogenic and abortifacient potential. (Francis Brinker.)

The root and root bark are rich in alkaloids, the most important being reserpine, others, around 30, which include ajmaline, ajmalicine (raubasine), ajmalicine, yohimbine, coryanthine, iso-ajmaline, neo-ajmaline, papaver- ine, raubasine, rauwolscine, rescin- namine, reserpine, sarpagine, serpentine, serpentinine, serpinine and de- serpidine.

Reserpine is hypotensive and tranquilizer, used for certain forms of mental disorders. Ajmalicine (raubasine) and rescinnamine are also hypoten- sive and tranquilizer. Deserpidine is sedative, as well as hypotensive. Aj- maline exhibits antiarrhythmic activity.

A number of Rauvolfia species are found in India: R. beddomei Hook. f.; R. densiflora Benth ex Hook. f. (Himalayas, Khasi and Aka Hills; Western and Eastern Ghats); R. micrantha Hook. f; known as Malabar Rauvolfia, (Kerala, up to an altitude of 300 m)

The roots of R. beddomei contain ajmalicine, sarpagine and serpentine, but no reserpine. R. densiflora yielded 0.51% of total alkaloids (reserpine 0.01%). R. micrantha gave ajmalicine, raunamine, reserpiline, sarpagine, neosarpagine, in addition to reserpine.

(In classical Ayurvedic texts, Nakuli and Gandha-naakuli were included in compound formulations for mental diseases.)... rauvolfia serpentina

Raynaud’s Disease

So called after Maurice Raynaud (1834–81), the Paris physician who published a thesis on the subject in 1862. This is a condition in which the circulation (see CIRCULATORY SYSTEM OF THE BLOOD) becomes suddenly obstructed in outlying parts of the body. It is supposed to be due to spasm of the smaller arteries in the affected part, as the result of them responding abnormally to impuilses from the SYMPATHETIC NERVOUS SYSTEM. Its effects are increased both by cold and by various diseases involving the blood vessels.

Symptoms The condition is most commonly con?ned to the occurrence of ‘dead ?ngers’ – the ?ngers (or the toes, ears, or nose) becoming white, numb, and waxy-looking. This condition may last for some minutes, or may not pass o? for several hours, or even for a day or two.

Treatment People who are subject to these attacks should be careful in winter to protect the feet and hands from cold, and should always use warm water when washing the hands. In addition, the whole body should be kept warm, as spasm of the arterioles in the feet and hands may be induced by chilling of the body. Su?erers should not smoke. VASODILATORS are helpful, especially the calcium antagonists. In all patients who do not respond to such medical treatment, surgery should be considered in the form of sympathectomy: i.e. cutting of the sympathetic nerves to the affected part. This results in dilatation of the arterioles and hence an improved blood supply. This operation is more successful in the case of the feet than in the case of the hands.... raynaud’s disease

Raynauds Either Syndrome Or Disease

The first is less severe, characterized by blanching spasms of blood vessels leading to the hands and feet, initiated by cold, moisture, even emotional stress and low blood sugar. Sort of a finger migraine. After the spasm relaxes, the tissue distal becomes red, hot, even painful. R. Disease is more serious and perhaps deriving from different causes as well. The spasms may not subside, the effected tissues can become purplish, and in extreme cases, gangrenous.... raynauds either syndrome or disease

Read Codes

These form an agreed UK thesaurus of health-care terminology named after the general practitioner who devised them initially in the 1970s. The coding system provides a basis for computerised clinical records that can be shared across professional and administrative boundaries. Such records have essential safeguards for security and con?dentiality. The codes accommodate the di?erent views of specialists, but use simple terms without any loss of the ?ne detail necessary in specialist terminology. The Read Codes are being merged with the world’s other leading coding and classi?cation system: the College of American Pathologists’ Systemised Nomenclature of Medicine (SNOMED-RT).... read codes

Reaginic Antibody

As used by immunologists, this term refers to IgE antibodies. As used by microbiologists, it refers to antibodies produced in syphilis – probably in response to the tissue damage caused by Treponema pallidum. Production of these antibodies in patients with syphilis has been utilised in the development of the non-treponemal serological tests for syphilis such as the VDRL Test, the RPR Test and the now superceded Wasserman Complement Fixation Test. These tests are useful in that they are only positive in active syphilis but they have many biological false positive reactions, including pregnancy.... reaginic antibody

Reconstructive (plastic) Surgery

Reconstructive surgery on the skin and underlying tissues that have been damaged or lost as a result of disease or injury. Congenital malformations are also remedied using reconstructive surgery. Surgeons graft healthy skin from another part of the body to repair skin damaged or destroyed by burns or injuries. New techniques are under development for growing new skin in the laboratory to be used in reconstructive surgery. Surgeons also repair damage using skin ?aps prepared in another part of the body – for example, a skin ?ap from the arm may be used to repair a badly injured nose or face. Reconstructive surgery is also used to repair the consequences of an operation for cancer of, say, the neck or the jaw. Plastic surgeons undertake cosmetic surgery to improve the appearance of noses, breasts, abdomens and faces.... reconstructive (plastic) surgery

Rectum, Diseases Of

The following are described under their separate dictionary entries: FAECES; HAEMORRHOIDS; FISTULA; DIARRHOEA; CONSTIPATION.

Imperforate anus, or absence of the anus, may occur in newly born children, and the condition is relieved by operation.

Itching at the anal opening is common and can be troublesome. It may be due to slight abrasions, to piles, to the presence of threadworms (see ENTEROBIASIS), and/or to anal sex. The anal area should be bathed once or twice a day; clothing should be loose and smooth. Local application of soothing preparations containing mild astringents (bismuth subgallate, zinc oxide and hamamelis) and CORTICOSTEROIDS may provide symptomatic relief. Proprietary preparations contain lubricants, VASOCONSTRICTORS and mild ANTISEPTICS.

Pain on defaecation is commonly caused by a small ulcer or ?ssure, or by an engorged haemorrhoid (pile). Haemorrhoids may also cause an aching pain in the rectum. (See also PROCTALGIA.)

Abscess in the cellular tissue at the side of the rectum – known from its position as an ischio-rectal abscess – is fairly common and may produce a ?stula. Treatment is by ANTIBIOTICS and, if necessary, surgery to drain the abscess.

Prolapse or protrusion of the rectum is sometimes found in children, usually between the ages of six months and two years. This is generally a temporary disorder. Straining at defaecation by adults can cause the lining of the rectum to protrude outside the anus, resulting in discomfort, discharge and bleeding. Treatment of the underlying constipation is essential as well as local symptomatic measures (see above). Haemorrhoids sometimes prolapse. If a return to normal bowel habits with the production of soft faeces fails to restore the rectum to normal, surgery to remove the haemorrhoids may be necessary. If prolapse of the rectum recurs, despite a return to normal bowel habits, surgery may be required to rectify it.

Tumours of small size situated on the skin near the opening of the bowel, and consisting of nodules, tags of skin, or cauli?ower-like excrescences, are common, and may give rise to pain, itching and watery discharges. These are easily removed if necessary. Polypi (see POLYPUS) occasionally develop within the rectum, and may give rise to no pain, although they may cause frequent discharges of blood. Like polypi elsewhere, they may often be removed by a minor operation. (See also POLYPOSIS.)

Cancer of the rectum and colon is the commonest malignancy in the gastrointestinal tract: around 17,000 people a year die from these conditions in the United Kingdom. Rectal cancer is more common in men than in women; colonic cancer is more common in women. Rectal cancer is a disease of later life, seldom affecting young people, and its appearance is generally insidious. The tumour begins commonly in the mucous membrane, its structure resembling that of the glands with which the membrane is furnished, and it quickly in?ltrates the other coats of the intestine and then invades neighbouring organs. Secondary growths in most cases occur soon in the lymphatic glands within the abdomen and in the liver. The symptoms appear gradually and consist of diarrhoea, alternating with attacks of constipation, and, later on, discharges of blood or blood-stained ?uid from the bowels, together with weight loss and weakness. A growth can be well advanced before it causes much disturbance. Treatment is surgical and usually this consists of removal of the whole of the rectum and the distal two-thirds of the sigmoid colon, and the establishment of a COLOSTOMY. Depending upon the extent of the tumour, approximately 50 per cent of the patients who have this operation are alive and well after ?ve years. In some cases in which the growth occurs in the upper part of the rectum, it is now possible to remove the growth and preserve the anus so that the patient is saved the discomfort of having a colostomy. RADIOTHERAPY and CHEMOTHERAPY may also be necessary.... rectum, diseases of

Reflex Action

One of the simplest forms of activity of the nervous system. (For the mechanism upon which it depends, see NERVOUS SYSTEM; NEURON(E).) Re?ex acts are divided usually into three classes.

Super?cial re?exes comprise the sudden movements which result when the skin is brushed or pricked, such as the movement of the toes that results from stroking the sole of the foot.

Deep re?exes depend upon the state of mild contraction in which muscles are constantly maintained when at rest, and are obtained, as in the case of the knee-jerk (see below), by sharply tapping the tendon of the muscle in question.

Visceral re?exes are those connected with various organs, such as the narrowing of the pupil when a bright light is directed upon the EYE, and the contraction of the URINARY BLADDER when distended by urine.

Faults in these re?exes give valuable evidence as to the presence and site of neurological disorders. Thus, absence of the knee-jerk, when the patellar tendon is tapped, means some interference with the sensory nerve, nerve-cells, or motor nerve upon which the act depends – as, for example, in POLIOMYELITIS, or peripheral NEURITIS; whilst an exaggerated jerk implies that the controlling in?uence exerted by the BRAIN upon this re?ex mechanism has been cut o? – as, for example, by a tumour high up in the SPINAL CORD, or in the disease known as MULTIPLE SCLEROSIS (MS).... reflex action

Reflux

Fluid ?owing in the opposite direction to normal (i.e. back ?ow). Often refers to regurgitation of stomach contents into the OESOPHAGUS (see also OESOPHAGUS, DISEASES OF), or of urine from the URINARY BLADDER back into the ureters (see URETER).... reflux

Regulation Of Health Professions

Professional sta? working in health care are registered with and regulated by several statutory bodies: doctors by the GENERAL MEDICAL COUNCIL (GMC); dentists by the GENERAL DENTAL COUNCIL; nurses and midwives by the Council for Nursing and Midwifery, formerly the UK Central Council for Nursing, Midwifery and Health Visiting (see NURSING); PHARMACISTS by the Royal Pharmaceutical Society; and the professions supplementary to medicine (chiropody, dietetics, medical laboratory sciences, occupational therapy, orthoptics, physiotherapy and radiography) by the Council for Professions Supplementary to Medicine. In 2002, the Council for the Regulation of Health Care Professions was set up as a statutory body that will promote cooperation between and give advice to existing regulatory bodies, provide a quality-control mechanism, and play a part in promoting the interests of patients. The new Council is accountable to a Select Committee of Parliament and is a non-ministerial government department similar in status to the FOOD STANDARDS AGENCY. It has the right to scrutinise the decisions of its constituent bodies and can apply for judicial review if it feels that a judgement by a disciplinary committee has been too lenient.... regulation of health professions

Reiter’s Syndrome

A condition probably caused by an immunological response to a virus (see IMMUNITY), in which the patient has URETHRITIS, ARTHRITIS and conjunctivitis (see under EYE, DISORDERS OF). The skin may also be affected by horny areas which develop in it. The disorder was ?rst described by a German physician, H. Reiter (1881–1969); it is more common in men than in women, and is the most common cause of arthritis in young men. It usually develops in people who have a genetic predisposition for it: around 80 per cent of sufferers have the HLA B27 tissue type. Treatment is symptomatic with ANALGESICS and NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS). (See also REACTIVE ARTHRITIS.)... reiter’s syndrome

Action: Root—used for the treatment of respiratory affections, common cold and influenza.

The roots contain about twice the amount of pristimerin as in R. indica and show similar antibiotic properties. Pristimerin is found active against Streptococcus viridans, causative organism for sore throat and tonsilitis, and S. pyogenes.... reissantia grahamii

Reissantia Indica

Halle.

Synonym: Hippocratea indica Willd. Pristimera indica A. C. Smith.

Family: Celastraceae; Hippo- crateaceae.

Habitat: North-eastern India.

Siddha/Tamil: Odangod.

Folk: Kazurati, Tirruli (Maharashtra), Atari-lataa, Kathapahaariaa, Lokhandi (Bengal).

Action: Root bark—used for the treatment of respiratory troubles. Stem—febrifuge. Leaves—scorched and given to women during confinement. Powdered leaves and roots are applied to sores and wounds.

The roots contain dulcitol. The root bark contains an antibiotic principle, pristimerin (0.1%) which shows considered in vitro activity against several Gram-positive cocci, both haemolyt- ic and non-haemolytic. Pristimerin also inhibits in vitro growth of different strains of Mycobacterium tuberculosis. Clinical trials have shown that pristimerin is effective in the treatment of inflammatory conditions of the naso-pharyngeal mucosa resulting from common cold and influenzal infections. It is found useful as an adjunct to the common antibiotic therapy of respiratory inflammations of both bacterial and viral origin, and is reported to possess antitumour properties, but its high toxicity precludes its use as a cancero-static agent.... reissantia indica

Relate Marriage Guidance

The idea of a marriage-guidance council came from a group of doctors, clergy and social workers who were concerned for the welfare of marriage. It is based upon two major concepts: that marriage provides the best possible way for a man and woman to live together and rear their children; and that the counsellors share a basic respect for the unique personality of the individual and his (or her) right to make his (or her) own decisions. The organisation consists of between 120 and 130 Marriage Guidance Councils throughout the country, comprising about 1,250 counsellors. These Councils are a?liated to Relate National Marriage Guidance, which is responsible for the selection, training and continued supervision of all counsellors. Anyone seeking help can telephone or write for an appointment. No fees are charged, but those receiving help are encouraged to donate what they can.... relate marriage guidance

Repressed Memory Therapy

Also called recovered memory syndrome, this treatment was developed in the wake of the widespread exposure in the 1980s and 90s of the frequency of child sexual abuse. A controversial concept emerged in the USA, picked up later by some experts in the UK, that abused children sometimes suppress their unpleasant memories, and that subsequent PSYCHOTHERAPY could help some victims to recover these memories – thus possibly aiding rehabilitation. This recall of ‘repressed’ memories, however, was believed by some psychiatrists to be, in e?ect, a false memory implanted into the victim’s subconscious by the psychotherapy itself – or perhaps invented by the individual for personal motives.

In 1997 the Royal College of Psychiatrists in the UK produced a comprehensive report which was sceptical about the notion that the awareness of recurrent severe sexual abuse in children could be pushed entirely out of consciousness. The authors did not believe that events could remain inaccessible to conscious memory for decades, allegedly provoking vague non-speci?c symptoms to be recovered during psychotherapy with resolution of the symptoms. Supporting evidence pointed to the lack of any empirical proof that unconscious dissociation of unpleasant memories from conscious awareness occurred to protect the individual. Furthermore, experimental and natural events had shown that false memories, created through suggestion or in?uence, could be implanted. Many individuals who had claimed to have recovered memories of abuse subsequently withdrew and, often, non-speci?c symptoms allegedly linked to suppression worsened rather than improved as therapy to unlock memories proceeded. The conclusion is that recovered memory therapy should be viewed with great caution.... repressed memory therapy

Research

In medicine, the collation and assessment of existing facts and knowledge, and the critical systematic investigation of the normal and abnormal functioning of the body, along with the EPIDEMIOLOGY of diseases and disorders affecting it – the aim being to increase the sum of knowledge in respect of the prevention, diagnosis and treatment of disease.

Ethics of research Although Britain has had legislation governing aspects of research on animals since the 19th century, there is no over-arching statute regulating research on humans and human material. Such activity is covered in law by the vaguely de?ned common-law concept of consent, and by piecemeal legislation such as the DATA PROTECTION ACT 1998 and the HUMAN FERTILISATION & EMBRYOLOGY ACT 1990. Nevertheless, extensive and very detailed ethical guidance on aspects of research has been published by a wide range of national and international organisations (see ETHICS COMMITTEES). Several basic principles feature in all statements about research ethics: these include the importance of ensuring that research is independently and rigorously scrutinised by appropriately constituted ethics committees; verifying that any risk to the research subject is reasonable in relation to the anticipated bene?t; and ensuring that all e?orts are made to minimise possible harm. The research subject’s willingness to tolerate some risk does not relieve researchers of the responsibility of making sure that all risks are kept to a minimum. Above all, a key feature of ethical research has involved seeking informed consent from research participants. This rule, initially applied to actual involvement by human subjects in research, has gradually been extended to include seeking informed consent from patients or from their relatives to the use of data and to the use of human organs and tissue in research, including after POST-MORTEM EXAMINATION. (See also EVIDENCE-BASED MEDICINE.)... research

Research Fraud And Misconduct

Research misconduct is de?ned as behaviour by a researcher that falls short of good ethical and scienti?c standards – whether or not this be intentional. For example, the same data may be sent for publication to more than one medical journal, which might have the e?ect of their being counted twice in any META-ANALYSIS or systematic review; or the data may be ‘salami sliced’ to try to make the maximum number of publications, even though the data may overlap. Fraud in the context of research is de?ned as the generation of false data with the intent to deceive. It is much less frequent than carelessness, but its incidence is estimated as between

0.1 and 1 per cent. A ?gure of 1 per cent means that, in the United Kingdom at any one time, maybe 30 studies are being conducted, or their results published, which could contain false information. Examples include forged ethics-committee approval, patient signatures and diary cards; fabricated ?gures and results; invention of non-existent patient subjects; or sharing one electrocardiogram or blood sample amongst many subjects.

Research fraud should be ?rst suspected by a clinical-trial monitor who recognises that data are not genuine, or by a quality-assurance auditor who cannot reconcile data in clinical-trial report forms with original patient records. Unfortunately, it often comes to light by chance. There may be suspicious similarities between data ostensibly coming from more than one source, or visits may have been recorded when it was known that the clinic was shut. Statistical analysis of a likely irregularity will frequently con?rm such suspicion. The motivation for fraud is usually greed, but a desire to publish at all costs, to be the original author of a medical breakthrough, to bolster applications for research grants, or to strengthen a bid for more departmental resources are other recognised reasons for committing fraud.

In the USA, those proved to have committed fraud are debarred from receiving federal funds for research purposes or from undertaking government-funded therapeutic research. The four Nordic countries (Denmark, Finland, Norway and Sweden) have committees on research dishonesty that investigate all cases of suspected research misconduct. In the United Kingdom, an informal system operated by the pharmaceutical industry, using the disciplinary mechanism of the General Medical Council (GMC), has led to more than 16 doctors in the past ten years being disciplined for having committed research fraud. Editors of many of the world’s leading medical journals have united to form the Committee on Publishing Ethics, which advises doctors on proper practice and assists them in retracting or refusing to publish articles found or known to be false. (See ETHICS; ETHICS COMMITTEES.) Where an author does not o?er a satisfactory explanation, the matter is passed to his or her institution to investigate; where an editor or the committee is not satis?ed with the result they may pass the complaint to the appropriate regulatory body, such as the GMC in Britain.... research fraud and misconduct

Resistance (host)

The sum total of body mechanisms which interpose barriers to the progress of invasion or multiplication of infectious agents, or to damage by their toxic products. 1. Immunity - That resistance usually associated with possession of antibodies having a specific action on the microorganism concerned with a particular infectious disease or on its toxin. Passive immunity is attained either naturally, by maternal transfer, or artificially, by inoculation of specific protective antibodies (convalescent or immune serum or immune serum (gamma) globulin (human) and is of brief duration (days to months). Active immunity lasting months to years is attained either naturally, by infection, with or without clinical manifestations, or artificially, byinoculation of fractions or products of the infectious agent or of the agent itself, in killed, modified or variant form. 2. Inherent resistance - An ability to resist disease independently of antibodies or of specifically developed tissue response; it commonly rests in anatomic or physiologic characteristics of the host; it may be genetic or acquired, permanent or temporary.... resistance (host)

Resistin

A new hormone (see HORMONES) recently identi?ed by researchers in the United States.

This resistance is a hallmark of this type of diabetes and is manifested throughout the body. THIAZOLIDINEDIONE DRUGS, a new class of antidiabetic drugs that lower insulin resistance, are mediated by receptors which are abundant in fat cells, and the researchers claim to have identi?ed a fat-cell PROTEIN that may be responsible for this and which they believe to be a hormone; it was also found in high concentrations in diabetic mice.... resistin

Reye’s Syndrome

A condition, now rare, which occurs predominantly in young children following a viral infection of the upper respiratory tract or a viral infection such as CHICKENPOX or INFLUENZA.

The cause is not known, but there is evidence that ASPIRIN may also play a part in its causation. Doctors recommend that children should be given PARACETAMOL in place of aspirin. The initial feature is severe, persistent vomiting and fever. This is followed by outbursts of wild behaviour, DELIRIUM and CONVULSIONS terminating in COMA and death, often from liver failure. The MORTALITY rate is around 23 per cent, and 50 per cent of the survivors may have persistent mental or neurological disturbances. The younger the patient, the higher the death rate and the more common the permanent residual effects. Since aspirin has no longer been licensed for use in children and young people the incidence of the condition has fallen dramatcally. Some cases, previously thought to be Reye’s syndrome, have subsequently turned out to have been due to certain inherited metabolic diseases and to be unconnected with aspirin.... reye’s syndrome

English: Buckthorn (related species).

Action: Plant—anticonvulsant, anti-inflammatory, anti-ulcer.

The plant contains kaempferol, kaempferol-7-O-methyl ether and kaempferol-4'-O-methyl ether.

The ethyl acetate soluble portion of the alcoholic extract showed anti- nociceptive, anticonvulsant and anti- inflammatory activity. Kaempferol-4'- O-methyl ether was found to exhibit central nervous system depressant, cardiac stimulant, antispasmodic and anti-inflammatory activity

The plant also contain emodin, which exhibited cardiac and intestinal stimulant, central nervous system depressant and analgesic activity in experimental animals.... rhamnus procumbens

Rhamnus Purshiana

DC.

Synonym: Frangulapurshiana (DC) A. Grey.

Family: Rhamnaceae.

Habitat: Native to Europe; introduced in Kashmir, Himachal Pradesh, Bhutan and the Nilgiris.

English: Buckthorn (related species), Cascara Sagrada, Sacred Bark.

Action: Bark—stool-softener, non-habit forming stimulant laxative, pancreatic stimulant. Used for dyspepsia and habitual constipation.

Key application: In occasional constipation. (German Commission E, ESCOP, WHO.) As a stimulant laxative. (The British Herbal Pharmacopoeia.)

The bark contains up to 10% an- thraquinone glycosides, consisting of the cascarosides A, B, C and D, about 70% of the total; other glycosides in minor concentrations include barbaloin, frangulin, chrysanol, glycosides based on emodin, aloe-emodin, emodin- oxanthrone and chrysophanol; dianthrones, and free aglycones.

The cascarosides act on large intestines and stimulate peristalsis. The emodin exhibits antispasmodic activity in isolated rat intestine. Its anti- inflammatory and antiseptic action was also demonstrated.

Rhamnus catharticus Linn., is equated with common Buckthorn, R. purpurea Edgew. with Purple Buckthorn. R. purpurea is found in the Himalayas from Kashmir to Nepal.

Dried bark of Rhamnus frangula L. (Alder Buckthorn) and dried ripe berries of Ramnus catharticus are also used against constipation. (German Commission E, WHO.)

Long term use or excessive amounts may cause albuminuria, haematuria, slowing ofintestinal transit and cardiac irregularities. (Sharon M. Herr.)

Rhamnus triquetra Brandis (known as Gudlei, Fagoraa, Gardhan in Punjab; Gaunt in Garhwal and Kumaon and Katheraa in Jaunsar) is found in the Himalayas from Kashmir to Nepal. The bark is used as a tonic, astringent and deobstruent. Kaempferol, its 7-O- methyl ether and 4'-O-methyl ether, physcion-8 beta-D-glucoside, emodin and its 8 beta-D-glucoside were isolated from the whole plant. Emodin exhibited CNS depressant activity. (Fi- toterapia, 65, 1994.) The plant exhibited significant anti-inflammatory and a nonspecific antispasmodic activity. It induced cardio-stimulation which might be due to the endogenous release of catecholamines.

Rhamnus napalensis Wall. ex M. Laws. (known as Archal in Nepal; Biringa and Birringguli in Assam) is found in eastern Himalayas and the hills and plains ofAssam, Bihar, Orissa, Madhya Pradesh and northern Andhra Pradesh, ascending up to an altitude of 2,000 m. The fruit, pounded and macerated in vinegar, is prescribed for the treatment of herpes.... rhamnus purshiana

Rheum Emodi

Wall. ex Meissn.

Synonym: R. australe D. Don.

Family: Polygonaceae.

Habitat: Sub-alpine Himalayas, from Kashmir to Sikkim at altitudes of 3,300-5,200 m.; also cultivated in Assam.

English: Indian Rhubarb, Himalayan Rhubarb.

Ayurvedic: Amlaparni, Pitamuuli, Gandhini Revatikaa. Revandachini (roots).

Unani: Revandchini.

Siddha/Tamil: Revalchinikattai, Nattirevaichini.

Action: Purgative, astringent, aperient. Used for constipation and atonic dyspepsia. Not advised for patients suffering from gout, rheumatism, epilepsy. (When given internally, the root imparts a deep tinge to the urine.)

The root gave emodin, emodin- 3-monomethyl ether, chrysophanol, aloe-emodin, rhein. These occur free and as quinone, anthrone or dianthrone glycosides. The astringent principle consists of gallic acid together with small amounts of tannin. The drug also contain cinnamic and rhe- inolic acids, volatile oil, starch and calcium oxalate. Two major glyco- sidic active principles, sennoside A and B, are present along with free an- thraquinones.

At low doses, the tannin exerts astringent effect and relieves diarrhoea; at higher doses anthraquinones stimulate laxative effect and relieve constipation. (Natural Medicines Comprehensive Database, 2007.)

There are three main types of rhubarbs—Chinese, Indian or Himalayan, and Rhapontic.

The Chinese rhubarb consists of the rhizomes and roots of Rheum palma- tum and R. officinale.

The Indian rhubarb consists of dried rhizomes of R. emodi and R. web- bianum; rhizomes and roots of R. moorcroftianum and R. spiciforme are also reported to be mixed with the drug. R. rhaponticum is the Rhapontic rhubarb.

Rheum moorcroftianum Royle (the Himalayas at altitudes of 3,0005,200 m., chiefly in Garhwal and Ku- maon) possesses properties similar to those of R. emodi and the roots are mixed with the latter.

Rheum spiciforme Royle (drier ranges of Kumaon and Sikkim at altitudes of 2,700-4,800 m.) also possesses purgative properties. The rhizomes and roots are mixed up with Himalayan rhubarb.

Rheum webbianum Royle (the western and central Himalayas at altitudes of 3,000-5,000 m.) is the source of Himalayan rhubarb.

Rheum palmatum is esteemed as the best type of (Chinese) rhubarb. Two new stilbene glycosides, 4'-O- methylpiceid and rhapontin, isolated from the roots, exhibited moderate alpha-glucosidase inhibitory activity. Anthraquinone glucoside, pul- matin, isolated from the roots, along with its congeners, chrysophanein and physcionin, showed cytotoxic activity against several types of carcinoma cells. Polysaccharides, isolated from the roots and rhizomes, contained lyx- ose, glucose, galactose, xylose, rham- nose, mannose and ribose.

Dosage: Root—0.2-1.0 g powder. (CCRAS.)... rheum emodi

Rheum Nobile

Hook. f. & Th.

Family: Polygonaceae.

Habitat: The Himalayas from Nepal to Bhutan at 3,900-4,800 m.

Folk: Tehuka (Sikkim).

Rheum Webbianum

Royle.

Habitat: Western Himalayas. Folk: Archa.

Action: Antispasmodic, muscle relaxant, antiseptic.

The rhizomes contain desoxyrha- pontigenin. The compound, like papaverine, exhibited smooth muscle relaxant activity in a wide variety of in vitro and in vivo tests. Aqueous alcoholic extract showed papaverine-like non-specific spasmolytic activity.

The paste of fresh rhizomes is applied on burns, blisters and boils to prevent scar formation.... rheum webbianum

Rheum Officinale

Baillon.

Family: Polygonaceae.

Habitat: Southeast Tibet, West and Northwest China.

English: Rhubarb.

Unani: Usaare Rewand.

Action: Astringent and cathartic (anthraquinones are laxative and tannins astringent), stomachic, aperient, cholinergic, gastric stimulant, antispasmodic, anti-inflammatory, antiseptic. Used for indigestion, diarrhoea, dysentery and disorders of liver and gallbladder.

Key application: In constipation. Contraindicated in acute intestinal inflammation and obstruction. (German Commission E, ESCOP, The British Herbal Pharmacopoeia, WHO.)

Rhubarb contains 1,8-dihydroxy- anthracene derivatives. The laxative effect of the herb is primarily due to its influence on the motility of the colon, inhibiting stationary and stimulating propulsive contractions. Stimulation of the chloride secretion increases the water and electrolyte content of stool. (German Commission E.)

The plant extract of R. officinale is found to be strong and effective scavenger of oxygen radicals in xan- thine/xanthine oxidase and other systems in vitro.

Rheum rhaponticum, known as Rha- pontic or English rhubarb, is extensively cultivated all over Europe and America; also cultivated to a small extent in India in the Khasi Hills, the Nilgiris and West Bengal.

Rhubarbs contain anthraquinones but English rhubarb contains only chrysophanic acid and some of its glycosides. Stilbene glycosides, present in other types, are also found in English rhubarb. The roots contain rhapontin. (1.42%), reported to restore oestrus cycle in castrated female rats.... rheum officinale

Rheumatoid

Broadly, having dull aching in joints, muscles, eyes, and so forth. In a more literal sense, it is having an autoimmune response, usually between certain IgM and IgE antibodies, that may have started as a bacterial infection or as some autoimmune reaction. The severity is increased under emotional, physical, dietary, and allergic stress­or any stress. Hans Selye showed a few years ago that once a chronic disease response occurs, any stress above metabolic tolerance will aggravate the chronic disease, which is why some people, stressed by cold, wet weather, must avoid it; but someone else is stressed by legumes, still another person gets upset (and stressed) by watching too much CNN. You know best what stresses you; it’s not fair to ask a doc to find it out for you. Rheumatoid arthritis is so named because it somewhat resembles the joint inflammations that can occur in rheumatic fever, a completely different disease caused by a strep infection.... rheumatoid

Rhubarb, Turkey

Rheum palmatum. N.O. Polygonaceae.

Habitat: China.

Rheum palmatum was once transported from China through Persia to Turkey and was consequently known as "Turkey Rhubarb" ; when conveyed via India it was called "East Indian Rhubarb." This Chinese root is the popular medicinal Turkey Rhubarb of to-day, the best kind being that from the Shansi province of China.

Features ? The root is smooth and heavy, and arrives in this country peeled. It is identifiable by the dark brown spots and a reticulation of white lines. The Canton rhubarb is more fibrous, unspotted, and the white network is less prominent than that from Shansi. The quality of these roots is judged by the fracture, which should show bright, the inferior kinds being a dull brown.

Action: Aperient, stomachic, astringent, tonic.

Small doses of the powdered root are used in diarrhea, larger quantities acting as a thorough yet gentle purgative. Dose of powdered root, 3 to 30 grains.... rhubarb, turkey

Ribes Nigrum

Linn.

Family: Grossulariaceae.

Habitat: Cold temperate regions extending from Himalayas to northern Asia and Europe.

English: European Black Currant.

Folk: Nabar.

Action: Dried leaves and twigs— a home remedy for coughs. Leaves—diuretic, hypotensive, refrigerant. An infusion is used for inflammatory conditions, sore throat, hoarseness. Fruits— refrigerant, mildly spasmolytic, vasoprotective, anti-inflammatory.

Black currents are very rich in vitamin C (average 150 mg/100g) and contain 0.9-1.7% pectin as calcium pec- tate, also minerals, potassium (372 mg/ 100 g). The acidity of the fruit is mainly due to citric acid; malic acid is present in small amounts. Glucose and fructose are principal sugars; sucrose is a minor component.

The flavonoids in the fruits include kaempferol, quercetin and myricetin. About 0.3% anthocyanosides, concentrated mainly in the skin, consist of glycosides of cyanidol and delphinidol.

The anthocyanosides are reportedly bacteriostatic and exhibit vasopro- tective and anti-inflammatory activity. They are antisecretory against cholera toxin-induced intestinal fluid secretion in vitro.

The leaves contain an anti-inflammatory principle, pycnometol and minute quantities of an essential oil composed mostly of terpenes.

Polyphenolic extract of buds inhibited lipid peroxidation by rat liver mi- crosomes.

Polyphenols present in R. nigrum and R. rubrum (Red Current, Western Himalayas from Kumaon to Kashmir) exhibit free radical scavenging activity. The seed oil lowers VLDL and total cholesterol.

Contraindicated in bleeding disorders. (Sharon M. Herr.)... ribes nigrum

Ribs

The bones, 12 on each side, which enclose the cavity of the chest. The upper seven are joined to the breast-bone by their costal cartilages and are therefore known as true ribs. The lower ?ve do not reach the breast-bone, and are therefore known as false ribs. Of the latter, the eighth, ninth and tenth are joined by their costal cartilages, each one to the rib immediately above it, while the 11th and 12th are free from any such connection and are therefore known as ?oating ribs. Each rib has a head, by which it is joined to the upper part of the body of the vertebra with which it corresponds, as well as to the vertebra immediately above. The greater part of the bone is made up of the shaft, which runs at ?rst outwards and at the angle turns sharply forwards. On the lower margin of the shaft is a groove, which lodges the corresponding intercostal artery and nerve.... ribs

Ricinus Communis

Linn.

Family: Euphorbiaceae.

Habitat: Cultivated chiefly in Andhra Pradesh, Maharashtra, Karnataka, and Orissa.

English: Castor seed.

Ayurvedic: Eranda, Chitra- bija, Triputi; Tribija, Vaataari, Chanchu, Manda, Uruvaka, Gandharva-hastaa, Panchaan- gula, Vardhamaana, Uttaanpatraka, Vyaaghrapuchha, Chitraa.

Unani: Bedanjeer, Arand.

Siddha/Tamil: Ammanakku.

Action: Oil from seeds and young leaf—purgative. Oil is used in dermatosis and eczema. Leaves— used as poultice to extract the worm.

Root—a decoction is administered for lumbago and allied complaints.

Bark—purgative.

The Ayurvedic Pharmacopoeia ofIn- dia recommends the decoction of the dried, mature root in rheumatism, pain in the urinary bladder, lumbago, diseases of the abdomen and inflammations; fresh leaf in helminthiasis, dysu- ria, arthritis, pain in the urinary bladder, dysuria, abscesses; dried seed powder in constipation, rheumatism, diseases of the liver and spleen, piles, lumbago, sciatica.

The root extract exhibited significant anti-inflammatory activity against carrageenan-, bradykinin-, 5-HT-and dextran-induced rat hind paw oedema. N-Demethylricinine showed dose-dependent anticholestatic and hepato- protective activities in rats.

Castor oil, derived from the seeds, is a well-known purgative (dose 520 ml).

Castor seed contains toxic components (2.8-3.0% on whole seed; about 10% in the flour) which are highly poisonous to human beings and animals. The principal toxic substance is the albumin, ricin. Allergens and a feebly toxic alkaloid ricinine is also present. An ulcerative factor in the seed is reported. Like other toxalbumins, ricin agglutinizes the mammalian red bleed corpuscles. (Ricin loses its toxicity and antigenic action on treatment with potassium permanganate.)

Castor oil consists principally of ri- cinoleic acid. Stearic, oleic, linoleic and dihydroxystearic acids are present in small amounts. The strong laxative property of castor oil is reported due to the local irritant action caused in the intestines by ricinoleic acid formed by hydrolysis under the influence of lipolytic enzymes. (The oil should not be used with fat-soluble vermifuge, it may increase its absorption and toxic- ity.)

Dosage: Root—20-30 g for decoction. (API, Vol. I.) Leaf—10- 20 ml juice; 2-5 g powder; seed— 0.5-3 g powder. (API, Vol. III.)... ricinus communis

In research using rats, the essential oil and ethanolic extract of rosemary decreased drug-induced hepatotoxici- ty and the suppression of bone marrow cells. Phenolic compounds in the herb exhibit antioxidant activity. (Sharon M. Herr.)

The herb contains volatile oil (1.02.5%), composed mainly of 1, 8-cineole (20-25%), alpha-pinene (15-25%), camphor (10-25%), others include bor- neol, isobutyl acetate, camphene, li- monene, linalool, 3-octanone, terpine- ol, verbenol; flavonoids including api- genin, diosmetin, diosmin; rosmarinic acid and other phenolic acids; diter- penes; rosmaricine; ursolic acid, olea- nolic acid and their derivatives.

The anti-inflammatory effect of Rosemary has been attributed to ros- marinic acid, ursolic acid and apigenin. Among flavonoids, diosmin is reported to be more effective in decreasing capillary fragility than rutin. A ros- maricine derivative exhibits stimulant and mild analgesic activity.

The phenolic fraction, isolated from the leaves, also from the oil, exhibits antioxidant activity.

Pressed juice of leaves possesses a strong antibacterial action on Staphylococcus aureus, E. coli and Bacillis sub- tilis.

An infusion of the plant with borax is used as a hair wash for preventing hair loss.

Tea For Lucid Dreams

Having a lucid dream means dreaming while being aware of the fact that you are dreaming. However, many people become lucid in the middle of the dream or, on the contrary, fall lose reality contact after being lucid at first. Although traditional medicine can’t be very helpful in these cases, alternative medicine has a few tricks up its sleeve. How a Tea for Lucid Dreams Works A Tea for Lucid Dreams’ main purpose is to make you recall what you have dreamed by calming your nervous system and improving your memory function. These teas are good for a number of other diseases, such as memory loss, headaches or migraines. However, talk to an herbalist or to your doctor before starting any kind of herbal treatment in order to make sure everything will be alright. Efficient Tea for Lucid Dreams In order to work properly, a Tea for Lucid Dreams needs to be both very efficient and one hundred percent safe (since lucid dreams are not exactly a medical problem, you may want to avoid developing one). A tea that is rich in antioxidants, nutrients, tannins, volatile oils and minerals (sodium, magnesium, iron, manganese) would be very adequate. You may want to avoid teas with a large amount of acid agents (they could cause stomach pain). If you don’t know which teas could be useful for lucid dreams, here’s a list for guidance: - Green Tea – contains all the ingredients necessary to sustain life, so it’s useful for a wide range of ailments, not just lucid dreams. If you’re suffering from infertility, anemia, asthenia, loss of appetite, digestive tract complaints or nervous system failure, this decoction could also be useful. However, you must avoid it at all costs if you’re experiencing some menstrual or menopausal symptoms. The same advice if you’re pregnant (it may cause uterine contractions and therefore miscarriage). - Valerian Tea – was been used as a sleep aid since ancient times, when the Romans and the Greeks took it before going to bed. This Tea for Lucid Dreams, thanks to its active compounds, is a mild sedative and could also work miracles on your nervous system. However, you need to make sure that you don’t exceed the number of cups recommended per day in order to avoid hallucinations, tiredness or even death. - Chamomile Tea – of course, the world’s greatest panacea shouldn’t be left aside. If you’re having trouble remembering your dreams, try a cup of Chamomile Tea before you go to bed! This Tea has a great fragrance and a pleasant smell. Plus, it’s one hundred percent safe so you can drink as much as you want. Tea for Lucid Dreams Side Effects When taken according to specifications, these teas are generally safe. However, exceeding the number of cups recommended per day may lead to a number of health problems, such as diarrhea, nausea, vomiting, upset stomach or even death! If you’ve been taking one of these decoctions for a while and you’re experience a negative response from your body, ask for medical assistance right away! Don’t take a Tea for Lucid Dreams if you’re pregnant, breastfeeding, on blood thinners or anticoagulants. The same advice in case you’re preparing for a surgery. If your doctor says it’s ok to start an herbal treatment, choose a tea that fits best your requirements and enjoy its wonderful benefits!  ... tea for lucid dreams

Ultraviolet Rays (uvr)

Invisible light rays of very short wavelength beyond the violet end of the sun’s spectrum. Ultraviolet-C (UVC) (wavelength <290 nm [nanometre – see APPENDIX 6: MEASUREMENTS IN MEDICINE]) is entirely absorbed by the earth’s atmosphere and would otherwise be lethally damaging. Ultraviolet-B (UVB – 290– 320 nm) intensity increases with altitude: it is greatest in midsummer and at midday and penetrates cirrhus cloud. UVB causes sunburn and also tanning. Ultraviolet-A (UVA – 320– 400 nm) penetrates deeper into our skins but does not cause sunburn; it is implicated in many photochemical reactions and PHOTODERMATOSES and in CARCINOGENESIS. UVR helps the skin to synthesise vitamin D.

Ultraviolet lamps produce UVR and are used to tan skin but, because of the risk of producing skin cancer (see SKIN, DISEASES OF), the lamps must be used with great caution.... ultraviolet rays (uvr)

Urine Retention

This occurs when URINE is produced by the kidneys but not voided by the bladder. It is generally less serious than ANURIA, in which urine is not produced.

Causes Neurological injury, such as trauma to the spinal cord, may cause bladder weakness, leading to retention, although this is rare. Obstruction to out?ow is more common: this may be acute and temporary, for example after childbirth or following surgery for piles (HAEMORRHOIDS); or chronic, for example, with prostatic enlargement (see PROSTATE GLAND). Commonly seen in elderly men, this leads to reduced bladder capacity, with partial emptying every few hours. Total retention is rare, but may result from a stricture, or narrowing, of the URETHRA (see also URETHRA, DISEASES OF AND INJURY TO) – usually the result of infection or injury – or to pressure from a large neighbouring tumour.

Retention is generally treated by regular use of a urethral catether (see CATHETERS), various types of which are available. Tapping of the bladder with a needle passed above the pubis is rarely necessary, but may occasionally be required in cases of severe stricture.... urine retention

Von Recklinghausen’s Disease

An inherited disease, now called neuro?bromatosis. About one case occurs every 3,000 live births.

Licencing Of Herbal Remedies – Exemptions From

There are remedies that may be manufactured or assembled by any person carrying on a business or practice provided he or she is occupier of the premises which are closed to exclude the general public. The person (i.e. practitioner) supplies or sells the remedy to a particular person (i.e. patient) having been requested by or on behalf of that person and in that person’s presence to use his/her own judgement as to treatment.

Anyone may administer a herbal product to a human being, except by injection. Under Section 12 of the Medicines Act 1968, any remedy may be sold or supplied which only specifies the plant and the process. The remedy shall be called by no other name. This applies to the process producing the remedy consisting only of drying, crushing and comminuting. It must be sold without any written recommendation for use.

Those who have a manufacturer’s licence, or who notify the Enforcement Authority (the Secretary of State and the Pharmaceutical Society) can sell dried, crushed or comminuted herbs which have also been subjected to certain other limited processes (tablet-making, etc) but not those herbs contained in the Schedule to the Medicines (Retail Sale or Supply of Herbal Remedies) Order 1977 (SI 1977 No.2130).

This Schedule has three parts.

Part 1 contains substances that may only be sold by retail at registered pharmacies under the supervision of a pharmacist.

Part 2 refers to remedies that can be sold only in a registered pharmacy. There is, however, an important exception, as follows.

Part 3 contains a list of considered toxic herbs. A practitioner can prescribe all remedies that a shopkeeper can sell. He may also prescribe and sell remedies on Part 3 of the Schedule which a shopkeeper cannot. Such supply must be in premises closed to the public and subject to a clear and accurate indication of maximum dosage and strength. These remedies are as follows:... licencing of herbal remedies – exemptions from

Fight-or-flight Response

Arousal of the sympathetic part of the autonomic nervous system in response to fear but which also occurs in anxiety disorders. Adrenaline (epinephrine), noradrenaline (norepinephrine), and other hormones are released from the adrenal glands and nervous system, leading to a raised heart-rate, pupil dilation, and increased blood flow to the muscles. These effects make the body more efficient in either fighting or fleeing the apparent danger.... fight-or-flight response

Ozone Radiation

Harmful ultraviolet radiation from depletion of the ozone layer may affect general health and cause skin cancers, cataracts and immune deficiency. The protection offered by antioxidant nutrients can play a part in reducing the incidence of lens cataract. Until scientific medicine discovers effective treatment it would appear that Vitamins A, E, and Evening Primrose oil have a role to play in protection of the eyes and skin. Horsetail, rich in silica, is believed to delay progression of cataract when taken internally.

Alcohol-related Disorders

A wide variety of physical and mental disorders associated with heavy, prolonged consumption of alcohol.

High alcohol consumption increases the risk of cancers of the mouth, tongue, pharynx (throat), larynx (voice box), and oesophagus, especially if combined with smoking. Incidence of liver cancer, as well as the liver diseases alcoholic hepatitis and cirrhosis, is higher among alcoholics. High alcohol consumption increases the risk of cardiomyopathy, hypertension, and stroke. Alcohol irritates the digestive tract and may cause gastritis. Heavy drinking in pregnancy increases the risk of miscarriage and fetal alcohol syndrome. Alcoholics are more likely to suffer from anxiety and depression and to develop dementia.

Many alcoholics have a poor diet and are prone to diseases caused by nutritional deficiency, particularly of thiamine (see vitamin B complex). Severe thiamine deficiency, called beriberi, disturbs nerve function, causing cramps, numbness, and weakness in the legs and hands. Its effects on the brain can cause confusion, disturbances of speech and gait, and eventual coma (see Wernicke– Korsakoff syndrome). Severe thiamine deficiency can also cause heart failure.

A prolonged high level of alcohol in the blood and tissues can disturb body chemistry, resulting in hypoglycaemia (reduced glucose in the blood) and hyperlipidaemia (increased fat in the blood).

These may damage the heart, liver, blood vessels, and brain; irreversible damage may cause premature death.... alcohol-related disorders

Asbestos-related Diseases

A variety of diseases caused by inhalation of asbestos fibres. Asbestos is a fibrous mineral formerly used as a heat- and fire-resistant insulating material. There are 3 main types of asbestos fibre: white, which is widely used; blue; and brown, the most dangerous. The use of all types is now carefully controlled.

In asbestosis, widespread fine scarring occurs in the lungs. The disease causes breathlessness and a dry cough, eventually leading to severe disability and death. It develops mostly in industrial workers who have been heavily exposed to asbestos. The period from initial exposure to development of the disease is usually at least 20 years. Diagnosis is by chest X-ray. Asbestosis increases the risk of lung cancer.

Mesothelioma is a cancerous tumour of the pleura (the membrane surrounding the lungs) or the peritoneum (the membrane lining the abdominal cavity). In the pleura, mesotheliomas cause pain and breathlessness; in the peritoneum they cause enlargement of the abdomen and intestinal obstruction. The condition cannot be treated and usually leads to death within 1 or 2 years. The average interval between initial exposure to asbestos and death is 20–30 years. Mesothelioma affects people who have worked with blue or brown asbestos.

In diffuse pleural thickening, the outer and inner layers of the pleura become thickened, and excess fluid may accumulate in the cavity between them.

This combination restricts the ability of the lungs to expand, resulting in shortness of breath.

The condition may develop even after short exposure to asbestos.... asbestos-related diseases

Raised Edge

Shallow of carcinoma ulcer the skin pigment melanin. The risk is reduced by avoiding overexposure to strong sunlight, using sunscreens, and wearing protective clothing and sun hats. Without treatment, the carcinoma gradually invades and destroys surrounding tissues but virtually never spreads to other parts of the body. Treatment is usually with surgery (or in some cases radiotherapy) and is often completely successful. Plastic surgery may also be needed, however, depending on the size and site of the tumour. People who have had a basal cell carcinoma may develop new tumours and should be alert to any changes in their skin. (See also melanoma, malignant; squamous cell carcinoma; sunlight, adverse effects of.)... raised edge

Finger-joint Replacement

A surgical procedure in which one or more artificial joints made of metal, plastic, or silicone rubber are used to replace finger joints destroyed by disease, usually rheumatoid arthritis or osteoarthritis.

The procedure is usually successful in relieving arthritic pain and enabling the patient to use his or her hands again, but it rarely restores normal movement.... finger-joint replacement

Fluid Retention

Excessive accumulation of fluid in body tissues. Mild fluid retention is common with premenstrual syndrome but disappears with the onset of menstruation. However, more severe fluid retention may be associated with an underlying heart, liver, or kidney disorder (see ascites; nephrotic syndrome; oedema). Diuretic drugs may be used to treat the condition.... fluid retention

Hair Removal

Hair is usually removed from the body for cosmetic reasons.

It may also be shaved from around an incision site before surgery.

Temporary methods include shaving, waxing, depilatory creams, and waxing; electrolysis is the only permanent method of removal.... hair removal

Hernia Repair

Surgical correction of a hernia.

Surgery is usually performed to treat a hernia of the abdominal wall that is painful or cannot be pushed back into place.

A strangulated hernia requires an emergency operation.

During surgery, the protruding intestine is pushed back into the abdomen and the weakened muscle wall is strengthened.

Either open or minimally invasive surgery may be used.... hernia repair

Energy Requirements

The amount of energy that is needed by a person for cell metabolism, muscular activity, and growth. This energy is provided by the breakdown of carbohydrates, fats, and proteins supplied by food in the diet and by stored nutrients in the liver, muscles, and adipose tissue.

Energy is needed to maintain the heartbeat, lung function, and constant body temperature. The rate at which these processes use energy is called the basal metabolic rate (BMR). Any form of movement increases energy expenditure above the BMR. A person’s energy requirement increases during periods of growth and during pregnancy and lactation. When more energy is ingested as food than is used, the surplus is stored and there is usually a gain in weight. When less energy is consumed than is spent, weight is usually lost as the stores are used up. (See also nutrition; obesity.)... energy requirements

See H-receptor antagonists.... histamine-receptor antagonists

Ileitis, Regional

An outdated name for Crohn’s disease.... ileitis, regional

Interstitial Radiotherapy

Treatment of a cancerous tumour by inserting radioactive material into the growth or into neighbouring tissue. Using this method, also called brachytherapy, radiation can be targeted at the diseased area.

Radioactive material (usually artificial radioisotopes) contained in wires, small tubes, or seeds is then implanted into or near the diseased tissue under general anaesthesia. The material is left in place for variable amounts of time depending on the radioactive substance and the tumour being treated. (See also intracavitary therapy; radiotherapy.)... interstitial radiotherapy

Intrauterine Growth Retardation

Poor growth in a fetus, usually resulting from a failure of the placenta to provide adequate nutrients (often related to pre-eclampsia) or sometimes from a fetal defect. Severe maternal disease, such as chronic kidney failure, can reduce fetal growth. Fetal problems such as an intrauterine infection or genetic disorder can also impair growth. Smoking during pregnancy may reduce fetal growth and birth weight.

Intrauterine growth retardation may be suspected on antenatal examination;... intrauterine growth retardation

Keratotomy, Radial

A now uncommon procedure in which radiating incisions are made in the cornea (up to, but not through, its innermost layer) to reduce myopia.

Radial keratotomy has been largely replaced by laser procedures, such as LASIK, which carry less risk of permanent damage to the eye.... keratotomy, radial

Leukotriene Receptor Antagonists

A group of antiallergy drugs, such as montelukast and zafirlukast, used to prevent symptoms of mild to moderate asthma. The drugs work by blocking the effects of leukotrienes – naturally occurring substances released in the lungs during an allergic reaction.

Because they are not bronchodilator drugs, and will not relieve an existing attack, they are usually used with bronchodilators and inhaled corticosteroids to reduce the frequency of attacks.

Side effects include gastrointestinal disturbances and headache.

Skin and hypersensitivity reactions may also occur.... leukotriene receptor antagonists

Lip-reading

A way of understanding speech by interpreting movements of the mouth and tongue. Lip-reading is often used by people who are deaf.

liquid paraffin A lubricant laxative drug obtained from petroleum. It can cause anal irritation, and prolonged use may impair the absorption of vitamins from the intestine into the blood. lisinopril An ACE inhibitor drug commonly used to treat hypertension. lisp A common speech disorder caused by protrusion of the tongue between the teeth so that the “s” sound is replaced by “th”. Sometimes the cause is a cleft palate (see cleft lip and palate). In most children, there is no physical defect and lisping disappears by the age of about 4. listeriosis An infection that is common in animals and may also affect humans. It is caused by the bacterium LISTERIA MONOCYTOGENES, which is widespread in the environment, especially in soil. Possible sources of human infection include soft cheese, ready-prepared coleslaw and salads, and improperly cooked meat.

In most adults, the only symptoms are fever and aching muscles. There may also be sore throat, conjunctivitis, diarrhoea, and abdominal pain. Pneumonia, septicaemia, and meningitis may develop in severe cases. However, listeriosis can be life-threatening, particularly in elderlypeople, those with reduced immunity, and newborn babies. In pregnant women, infection may cause a miscarriage.

The condition is diagnosed by blood tests and analysis of other body fluids, such as urine. Treatment is with antibiotic drugs, such as ampicillin.... lip-reading

Livedo Reticularis

A net-like, purple or blue mottling of the skin, usually on the lower legs, caused by the enlargement of blood vessels beneath the skin.

It is more common in people with vasculitis and those who suffer from excessive sensitivity to cold.

The condition is harmless, and tends to be worse in cold weather.... livedo reticularis

Methicillin-resistant Staphylococcus Aureus

See MRSA.... methicillin-resistant staphylococcus aureus

Muscle-relaxant Drugs

A group of drugs used to relieve muscle spasm and spasticity. Muscle-relaxant drugs are used mainly in the treatment of nervoussystem disorders such as multiple sclerosis and painful muscular conditions such as torticollis. They are occasionally used to relieve muscle rigidity caused by injury. Some types are used to cause temporary paralysis during surgery under general anaesthesia.Except for dantrolene, muscle-relaxant drugs partly block nerve signals that stimulate muscle contraction. Dantrolene interferes with the chemical activity in muscle cells needed for contraction.

The drugs may cause muscle weakness and drowsiness. In rare cases, dantrolene causes liver damage.... muscle-relaxant drugs

Neck Dissection, Radical

Pain Relief

The treatment of pain, usually with analgesic drugs. Paracetamol, aspirin and codeine are the most widely used drugs in this group. Pain accompanied by inflammation is often alleviated by nonsteroidal anti-inflammatory drugs (NSAIDs). Severe pain may require treatment with opioids, such as morphine.

Other methods of pain relief include massage, ice-packs, poultices, TENS, acupuncture, or hypnosis. Surgery to destroy pain-transmitting nerves (as in a cordotomy) is occasionally performed when other treatments fail.... pain relief

Raynaud’s Phenomenon

A circulatory disorder affecting the fingers and toes that shares the mechanism, symptoms, and signs of Raynaud’s disease but results from a known underlying disorder.

Possible causes include arterial diseases, such as atherosclerosis; connective tissue diseases, such as rheumatoid arthritis; and various drugs, such as beta-blocker drugs.

The disorder is an occupational disorder of people who use pneumatic drills, chain saws, or vibrating machinery; it is sometimes seen in typists, pianists, and others whose fingers suffer repeated trauma.

Treatment is the same as for Raynaud’s disease, along with treatment of the underlying disorder.... raynaud’s phenomenon

Radiation Hazards

Hazards from radiation may arise from external sources of radiation or from radioactive materials taken into the body. The effects depend on the dose, the duration of exposure, and the organs exposed.

With some forms of radiation, damage occurs when the radiation dose exceeds a certain limit, usually 1 sievert (Sv) (see radiation unit). This damage may include radiation dermatitis, cataracts, organ failure (which may occur many years later), or radiation sickness.

For other types of radiation damage, the risk that damage will occur increases with increasing doses of radiation. Cancer caused by radiation-induced mutation is the major example of this type of damage. Radioactive leaks from nuclear reactors can cause a rise in mutation rates, which may lead to an increase in cancers, such as leukaemias; to birth defects; and to hereditary diseases. Cancer usually develops years after exposure. Radiation damage can be controlled by limiting exposure. People exposed to radiation at work have their exposure closely monitored to ensure that it does not exceed safe limits. People of reproductive age or younger should have their reproductive organs shielded when having X-rays or radiotherapy.There is no evidence of radiation hazards with visual display units (VDUs).... radiation hazards

Radiation Unit

Several different internationally agreed units (called units) are used to measure ionizing radiation. For example, the roentgen (R) measures the amount of radiation in the air, and the becquerel is the unit of spontaneous activity of a radioactive source such as uranium. For medical purposes, the most commonly used units are the gray (Gy) and the sievert (Sv).

The gray is the unit of radiation that is actually absorbed by any tissue or substance as a result of exposure to radiation. 1 Gy is the absorption of 1 joule of energy (from gamma radiation or X-rays) per kilogram of irradiated matter. The gray supersedes an older unit called the rad (1 Gy = 100 rads).

Because some types of radiation affect biological organisms more than others, the sievert is used as a measure of the impact of an absorbed dose. It uses additional factors, such as the kind of radiation and its energy, to quantify the effects on the body of equivalent amounts of different types of absorbed energy. The sievert replaces an older unit, the rem (1 Sv=100 rems).... radiation unit

Radionuclide Scanning

A diagnostic technique based on detection of radiation emitted by radioactive substances introduced into the body. Substances are taken up to different degrees by different tissues, allowing specific organs to be studied. For example, iodine is taken up mainly by the thyroid gland, so by “tagging” a sample of iodine with a radioactive marker (radionuclide), the uptake of iodine can be monitored to investigate the functioning of the gland. A radionuclide is swallowed or injected into the blood and accumulates in the target organ. It emits radiation in the form of gamma radiation, which is detected by a gamma camera to produce an image. Cross-sectional images (“slices”) can be obtained using a computer-controlled gamma camera that rotates around the patient. This specialized form of radionuclide scanning is known as (single photon emission computed tomography). Moving mation on blood flow, the movement of the heart walls, the flow of urine through the kidneys, and bile flow through the liver.

Radionuclide scanning is a safe procedure, requiring only minute doses of radiation that are excreted within hours. The radionuclides carry virtually no risk of toxicity or hypersensitivity.... radionuclide scanning

Rats, Diseases From

Rats are rodents that live close to human habitation. They damage and contaminate crops and food stores and can spread disease. The organisms responsible for plague and a type of typhus are transmitted to humans by the bites of rat fleas. Leptospirosis is caused by contact with anything contaminated by rat’s urine.

Rat-bite fever is a rare infection transmitted directly by a rat bite. There are 2 types of this infection, caused by different bacteria. The symptoms include inflammation at the site of the bite and in nearby lymph nodes and vessels, bouts of fever, a rash, and, in one type, painful joint inflammation. Treatment for both types is with antibiotic drugs.

Rabies virus can be transmitted by the bites of infected rats. Lassa fever, also a viral disease, may be contracted from the urine of rats in West Africa. Rats also carry the viral infection lymphocytic chorio-meningitis, as well as the bacterial infection tularaemia.... rats, diseases from

Receding Gums

Withdrawal of the gums from around the teeth, exposing part of the roots. The teeth may be sensitive to hot and cold substances, and the attachment of the tooth in the socket may weaken, causing the tooth to become loose. Severe cases of receding gums are usually a signs of gum disease (see periodontitis; gingivitis).... receding gums

Reconstructive Surgery

See arterial reconstructive surgery; plastic surgery.... reconstructive surgery

Rectum, Cancer Of

A cancerous tumour in the rectum. The cause is unknown, but dietary factors and genetic factors are thought to play a part. It is more common between ages 50 and 70.

Early symptoms are rectal bleeding during defecation and diarrhoea or constipation. Later, pain may occur. Left untreated, the cancer may eventually cause severe bleeding and pain and block the intestine. It may also spread to other organs.

The cancer may be detected by a rectal examination and confirmed with proctoscopy or sigmoidoscopy and biopsy.

Treatment is usually with surgery. For a tumour in the upper rectum, the affected area and the last part of the colon are removed and the 2 free ends of the intestine are sewn together. To promote healing, a temporary colostomy may be made. For a growth in the lower rectum, the entire rectum and anus are removed. Because there is no outlet for faeces, a permanent colostomy is created.

Radiotherapy and anticancer drugs may be used in addition to or instead of surgery.

Up to 40 per cent of people treated for rectal cancer live for 10 years or more.... rectum, cancer of

Reflex, Primitive

An automatic movement in response to a stimulus that is present in newborn infants but disappears during the first few months after birth. Primitive reflexes are believed to represent actions that were important in earlier stages of human evolution. They include the grasp reflex when something is placed in the hand and the rooting reflex, which enables a baby to find the nipple. The rooting reflex can be evoked by touching the baby’s cheek with the fingertip. These reflexes are tested after birth to give an indication of the condition of the nervous system.... reflex, primitive

Rehydration, Oral

See rehydration therapy.... rehydration, oral

Rehydration Therapy

The treatment of dehydration by administering fluids and salts by mouth (oral rehydration) or by intravenous infusion.

The amount of fluid necessary depends on age, weight, and the degree of dehydration.

Mild dehydration can usually be treated with oral solutions, which are available as effervescent tablet or powder to be made up at home.

In severe dehydration, or if the patient cannot take fluids by mouth because of nausea or vomiting, an intravenous infusion of saline and/or glucose solution may be given in hospital.... rehydration therapy

Reimplantation, Dental

Replacement of a tooth in its socket after an accident so that it can become reattached to supporting tissues. The front teeth are most commonly involved. The tooth needs to be reimplanted soon after the accident and is maintained with a splint (see splinting, dental) while it heals. Healing may take several weeks.... reimplantation, dental

Relationship Counselling

Formerly known as marriage guidance, relationship counselling is a type of professional therapy for established partners aimed at resolving the problems within their relationship.

The couple attends regular sessions together in which the counsellor promotes communication and attempts to help resolve differences between the partners.

Relationship counselling is largely based on the ideas and methods of behaviour therapy.

If some of the couple’s problems are sexual, the counsellor may refer them for sex therapy.... relationship counselling

Relaxation Techniques

Methods of consciously releasing muscular tension to achieve mental calm.

They can assist people with anxiety symptoms, help to reduce hypertension, and relieve stress, and may help pregnant women to cope with labour pains (see childbirth, natural).

Active relaxation consists of tensing and relaxing each of the muscles in turn.

Passive relaxation involves clearing the mind and concentrating on a phrase or sound.

Breathing exercises help to prevent hyperventilation, which often brings on or worsens anxiety.

Traditional concentration methods, such as yoga and meditation, employ similar techniques.... relaxation techniques

Resorption, Dental

Loss of substance from teeth. The loss may be external (affecting the surface of the root) or internal (affecting the wall of the pulp cavity). External resorption is part of the processs by which primary teeth are lost. Some degree of external resorption also occurs as part of the aging process, and may also be due to injury, inflammation of surrounding tissues, or pressure, for example from an impacted tooth.

Internal resorption is rare, occurring in about 1 percent of adults.... resorption, dental

Respiratory Failure

A condition in which there is a buildup of carbon dioxide and a fall in the level of oxygen in the blood (see hypoxia). Causes include lung disorders, such as severe asthma, emphysema, or chronic bronchitis (see pulmonary disease, chronic obstructive), or damage to the respiratory centre in the brain due to, for example, an overdose of opioid drugs, a stroke, or serious head injury.

Treatment is with ventilation and oxygen for the underlying cause.... respiratory failure

Reproductive System, Female

The female organs involved in ovulation, sexual intercourse, nourishing a fertilized ovum until it has developed into a full-grown fetus, and childbirth. With the exception of the vulva, which protects the opening of the vagina, these organs lie within the pelvic cavity.

Ova (eggs) are released at monthly intervals from the 2 ovaries, which also secrete oestrogen hormone; and progesterone hormones that control the reproductive cycle. The ova travel through the fallopian tubes to the uterus. Fertilization takes place if a sperm released into the vagina during sexual intercourse travels through the cervix and uterus to penetrate an ovum while it is in the fallopian tube.... reproductive system, female

Reproductive System, Male

The male organs involved in the production of sperm and in sexual intercourse. Sperm and male sex hormones (androgen hormones) are produced in the testes, which are suspended in the scrotum. From each testis, sperm pass into an epididymis, where they mature and are stored. Shortly before ejaculation, sperm are propelled into a duct called the vas deferens, which carries the sperm to the seminal vesicles behind the bladder. These 2 sacs produce seminal fluid, which is added to the sperm to produce semen.

Semen travels along 2 ducts to the urethra.

The ducts pass through the prostate gland, which produces secretions that are added to the semen.

At orgasm, semen is ejaculated from the urethra through the erect penis, which is placed in the woman’s vagina during sexual intercourse.... reproductive system, male

Respiratory Function Tests

See pulmonary function tests.... respiratory function tests

Respiratory Tract Infection

Infection of the breathing passages, which extend from the nose to the alveoli. This type of infection is divided into upper and lower respiratory tract infections. Upper respiratory tract infections affect the nose, throat, sinuses, and larynx. They include the common cold, pharyngitis, tonsillitis, sinusitis, laryngitis, and croup. Lower respiratory tract infections, which affect the trachea, bronchi, and lungs, include acute bronchitis, acute bronchiolitis, and pneumonia.... respiratory tract infection

Restless Legs

A syndrome characterized by unpleasant tickling, burning, prickling, or aching sensations in the leg muscles.

Symptoms tend to come on at night in bed; they may also be triggered by prolonged sitting.

The condition tends to run in families and is common in middleaged women, people with rheumatoid arthritis, smokers, and during pregnancy.

The cause is unknown, and there is no single cure; some patients benefit from cooling the legs, others from warming them.

Treatment with levodopa and calcium channel blockers can sometimes help.... restless legs

Restoration, Dental

The reconstruction of part of a damaged tooth. Restoration also refers to the material or substitute part used to rebuild the tooth. Small repairs are usually made by filling the tooth. For extensive repairs, a dental inlay or a crown may be used. Chipped front teeth may be repaired by bonding (see bonding, dental).... restoration, dental

Retinal Haemorrhage

Bleeding into the retina from 1 or more blood vessels, due to diabetes mellitus, hypertension, or retinal vein occlusion. When the macula

(site of central vision) is involved, vision is severely impaired.

Peripheral haemorrhages may be detected only when the eye is examined with an ophthalmoscope.... retinal haemorrhage

Retinal Tear

The development of a split in the retina, usually caused by degeneration.

A tear is more common in people with severe myopia.

A retinal tear may also be caused by a severe eye injury.

Retinal detachment usually follows a retinal tear.

If a retinal tear is found before there is any detachment, the hole is sealed by laser treatment or cryopexy (application of extreme cold).... retinal tear

Retinoscopy

A type of vision test in which a beam of light is shone from an instrument called a retinoscope into each eye in turn. The effect of different lenses on the beam of light determines whether glasses are needed for various refractive errors, such as hypermetropia, myopia, or astigmatism. Retinoscopy is particularly useful for assessing babies or young children.... retinoscopy

Rhesus Immunoglobulin

See anti-D(Rh) immunoglobulin.... rhesus immunoglobulin

Rhesus Incompatibility

A mismatch between the blood group of a Rhesus (Rh)-negative pregnant woman and that of her baby. In certain circumstances, this mismatch leads to haemolytic disease of the newborn.

The Rh system is based on the presence or absence in the blood of several factors, the most important of which is a substance called D antigen. Rh-positive blood contains D antigen, whereas Rhnegative blood does not. The blood type is determined by genes.Rhesus incompatibility results if a Rhnegative woman is exposed to the blood of her Rh-positive baby while it is being born. There are usually no problems during the first pregnancy with a Rh-positive baby. However, the woman may produce antibodies against the D antigen; in a subsequent pregnancy with a Rh-positive baby, these antibodies may cross the placenta and attack the red blood cells of the fetus. A Rhnegative woman can also be sensitized if she has had a miscarriage, abortion, or amniocentesis, in which the fetus’s Rhpositive blood enters her circulation.

Rhesus incompatibility is now uncommon because injections of anti-D(Rh0) immunoglobulin are given routinely to Rh-negative women during pregnancy and at delivery. They are also given after miscarriage, abortion, amniocentesis, or any procedure that might result in exposure of the mother to fetal blood cells.... rhesus incompatibility

Rhesus Isoimmunization

Rhinitis, Allergic

Inflammation of the mucous membrane lining the nose due to allergy to pollen, dust, or other airborne substances.

Also called hay fever, it causes sneezing, a runny nose, and nasal congestion.

Antihistamine drugs and topical corticosteroid drugs are used to treat mild attacks.

The drug sodium cromoglicate, inhaled regularly throughout the pollen season, may help to prevent attacks.

Long-term relief of symptoms can sometimes follow desensitization to a pollen allergen by a course of injections (see hyposensitization).... rhinitis, allergic

Ringing In The Ears

See tinnitus.... ringing in the ears

Rofecoxib

Common injuries include tendinitis, stress fractures, plantar fasciitis, torn hamstring muscles, back pain, tibial compartment syndrome, and shin splints.... running injuries

Selective Serotonin Reuptake Inhibitors

(SSRIs) A relatively new class of drugs that are used to treat depression.

They work by blocking the reabsorption of the neurotransmitter serotonin following its release in the brain.

The increased serotonin levels that result are associated with improved mood.

Common drugs in this group include fluoxetine and sertraline.

SSRIs are usually taken orally once a day; it may take 1–3 weeks for any noticeable improvement in symptoms.

SSRIs usually produce fewer side effects than other types of antidepressant drug.

However, they may cause diarrhoea, nausea, restlessness, and anxiety.... selective serotonin reuptake inhibitors

Tendon Rupture

A complete tear in a tendon.

A tendon may rupture when the muscle to which it is attached contracts suddenly and powerfully, such as during vigorous exercise.

Rupture may also be due to an injury or joint disorder such as rheumatoid arthritis.

Symptoms include a snapping sensation, impaired movement, pain, and swelling.

Diagnosis is usually obvious from the symptoms.

Surgery to repair the tendon may be needed.

In some cases, the tendon may heal if immobilized in a plaster cast.... tendon rupture

Uterine Muscle Relaxants

Drugs that are used to delay the premature delivery of a fetus. Beta2-adrenoceptor stimulants, such as salbutamol, relax the muscle of the uterus and may postpone labour for days or weeks in at-risk pregnancies of 24–33 weeks’ gestation. Delay of premature labour for up to 48 hours allows time for corticosteroid drugs to be given to the mother to help the fetal lungs to mature.... uterine muscle relaxants

Uterus, Retroverted

Urinary Retention

Inability to empty the bladder or difficulty in doing so. Urinary retention may be complete (urine cannot be passed voluntarily at all) or incomplete (the bladder fails to empty completely). In males, causes include phimosis, urethral stricture, prostatitis, a stone in the bladder (see calculus, urinary tract), and enlargement or tumour of the prostate (see prostate, enlarged; prostate, cancer of). In females, causes include pressure on the urethra from uterine fibroids or from a fetus. In either sex, the cause may be a bladder tumour. Retention may also be due to defective functioning of the nerve pathways supplying the bladder as a result of general or spinal anaesthesia, drugs affecting the bladder, surgery, injury to the nerve pathways, or disease of the spinal cord.

Complete retention causes discomfort and lower abdominal pain, except when nerve pathways are defective. The full bladder can be felt above the pubic bone. However, chronic or partial retention may not cause any serious symptoms. Retention can lead to kidney damage and, often, a urinary tract infection.Treatment of retention is by catheterization (see catheterization, urinary).

The cause is then investigated.

Obstruction can usually be treated; if nerve damage is the cause, permanent or intermittent catheterization is sometimes necessary.... urinary retention

Water Retention

Accumulation of fluid in body tissues (see oedema).... water retention

Weight Reduction

The process of losing excess body fat. A person who is severely overweight (see obesity) is more at risk of various illnesses, such as diabetes mellitus, hypertension (high blood pressure), and heart disease.

The most efficient way to lose weight is to eat 500–1,000 kcal (2,100–4,200 kJ) a day less than the body’s total energy requirements. Exercise also forms an extremely important part of a reducing regime, burning excess energy and improving muscle tone.

In most circumstances, drugs play little part in a weight loss programme.

However, sibutramine and orlistat may be useful adjuncts to a reducing diet and may be appropriate for some people with a high (see body mass index). Appetite suppressants related to amfetamines are not recommended.... weight reduction

Treatment is correction of the original cause, volume replacement, diuretics, oxygen, and mechanical ventilation.... adult respiratory distress syndrome

Age-related Macular Degeneration

(AMD, ARMD) see macular degeneration.... age-related macular degeneration

Alberti Regime

(GIK regime) a method for controlling blood-sugar levels in diabetic patients who are being fasted for whatever reason. It involves infusing a solution of glucose (G), insulin (I), and potassium (K) chloride intravenously over a standard time period. Blood sugar and potassium are measured frequently so that appropriate adjustments can be made to the mixture as necessary. [K. G. M. M. Alberti (1937– ), British physician]... alberti regime

Aortic Regurgitation

a leak of the aortic valve resulting in reflux of blood from the aorta into the left ventricle during diastole. Aortic regurgitation is most commonly due to degenerative ‘wear and tear’ of the aortic valve. Other causes include dilatation of the aortic root with secondary dilatation of the aortic valve, scarring of the aortic valve as a result of previous acute rheumatic fever, or destruction of the valve by infection (see endocarditis). Mild cases are symptom-free, but patients more severely affected develop breathlessness, angina pectoris, and enlargement of the heart; all have a diastolic murmur. A badly affected valve may be replaced surgically with a prosthesis.... aortic regurgitation

Aortic Replacement

a surgical technique used to replace a diseased length of aorta, most often the abdominal aorta. It usually involves inserting into the aorta a flexible tube of artificial material, which functions as a substitute for the diseased section.... aortic replacement

Asymmetric Tonic Neck Reflex

a primitive reflex that is present from birth but should disappear by six months of age. If the infant is lying on its back and the head is turned to one side, the arm and leg on the side to which the head is turned should straighten, and the arm and leg on the opposite side should bend (the ‘fencer’ position). Persistence of the reflex beyond six months is suggestive of *cerebral palsy.... asymmetric tonic neck reflex

Atheroembolic Renal Disease

a disease associated with diffuse atherosclerosis and sloughing of atheromatous plaques in the aorta and main renal arteries. This results in occlusion of smaller arteries and arterioles downstream within the kidney, with ischaemic and inflammatory reactions. This leads to the onset of renal impairment. Precipitating factors include invasive procedures with aortic cannulae, vascular surgery, and therapy with thrombolytics or anticoagulants. Less commonly the condition can occur spontaneously.... atheroembolic renal disease

Capillary Refill Time

a quickly performed test to assess the adequacy of circulation in an individual with poor cardiac output. An area of skin is pressed firmly by (say) a fingertip until it loses its colour; the number of seconds for the area to return to its original colour indicates capillary refill time. Normal capillary refill takes around 2 seconds. Slow capillary refill may occur globally in an individual with poor circulation or in a small area (e.g. a toe) in which local circulation is compromised (due, for example, to peripheral vascular disease). This test may not be very useful in people with dark skin.... capillary refill time

Cardiac Reflex

reflex control of the heart rate. Sensory fibres in the walls of the heart are stimulated when the heart rate increases above normal. Impulses are sent to the cardiac centre in the brain, stimulating the vagus nerve and leading to slowing of the heart rate.... cardiac reflex

Cation-exchange Resins

complex insoluble chemical compounds that may be administered with the diet to alter the *electrolyte balance of the body in the treatment of heart, kidney, and metabolic disorders. For example, in patients on a strict low-sodium diet such resins combine with sodium in the food so that it cannot be absorbed and passes out in the faeces.... cation-exchange resins

Cervical Resistance Index

measurement of the resistance of the cervix during the passage of a series of metal (Hegar) dilators. Lack of resistance in a nonpregnant women may suggest cervical weakness when she has experienced a previous second-trimester pregnancy loss or if she has had previous surgery to the cervix, and may indicate *cervical cerclage in the event of future pregnancies.... cervical resistance index

Cheyne–stokes Respiration

a striking form of breathing in which there is a cyclical variation in the rate, which becomes slower until breathing stops for several seconds before speeding up to a peak and then slowing again. It occurs when the sensitivity of the respiratory centres in the brain is impaired, particularly in states of coma. [J. Cheyne (1777–1836), Scottish physician; W. Stokes (1804–78), Irish physician]... cheyne–stokes respiration

The resultant image can be read by a laser beam and stored digitally or printed out as required. This system is widely used in conjunction with *PACS systems.... computerized radiography

Conditioned Reflex

a reflex in which the response occurs not to the sensory stimulus that normally causes it but to a separate stimulus, which has been learnt to be associated with it. In Pavlov’s classic experiments, dogs learned to associate the sound of a bell with feeding time and would salivate at the bell’s sound whether food was then presented to them or not.... conditioned reflex

Contralateral-routing-of-signal Hearing Aid

(CROS hearing aid) a form of hearing aid used to help people with severe or profound unilateral hearing loss. Sound information is collected by a microphone worn on the affected side and then transmitted by a thin wire or Bluetooth wireless technology to a device worn on the opposite side. If the hearing in the better ear is normal, no amplification is applied to the signal. If the better ear has a hearing loss the device also acts as a conventional hearing aid and amplifies the signal from both sides: this is known as a BICROS hearing aid.... contralateral-routing-of-signal hearing aid

Complex Regional Pain Syndrome

(CRPS, reflex sympathetic dystrophy, RSD, Sudek’s atrophy) neurological dysfunction in a limb following trauma, surgery, or disease, characterized by intense burning pain, swelling, stiffness, and sweaty shiny mottled skin. It is caused by overactivity of the sympathetic nervous system. The *ESR is often elevated, X-rays may reveal some patchy osteoporosis, and a bone scan usually demonstrates increased blood flow. Early treatment with splinting and physiotherapy are essential, in combination with *sympatholytic drugs, corticosteroids, and regional sympathetic blocks; *sympathectomy may be required in chronic cases.... complex regional pain syndrome

Co-registration

(fusion imaging) n. (in diagnostic imaging) the process of taking two images obtained by different techniques and (usually electronically) laying them on top of each other after suitable adjustment, so that the anatomical landmarks coincide. This can give more accurate information as one technique shows the anatomy and the other shows the pathology. Co-registering can thus show which part of the body is involved in the disease process. It is typically used in *PET/CT scanning. CT or MRI scans can also be fused onto real time ultrasound images to target a lesion for biopsy or treatment.... co-registration

Corneal Reflex

reflex blinking of both eyes normally elicited by lightly touching the cornea of one eye. This reflex is lost in deep coma, during general anaesthesia, and in death; it is therefore one of the tests used to confirm brainstem death.... corneal reflex

Corneal Ring

a ring designed to be inserted into the peripheral tissue of the cornea in order to alter the curvature of the corneal surface. It is undergoing trials to assess its ability to correct errors of refraction. In myopia (short-sightedness), for example, the ring would be required to stretch the corneal tissue peripherally and thus flatten the central corneal curvature in order to correct the myopia.... corneal ring

Corticotrophin-releasing Hormone

(CRH) a peptide hypothalamic hormone (of 41 amino acids) stimulating the release of *ACTH (adrenocorticotrophic hormone) from the anterior pituitary. Its own release is suppressed by a *negative feedback loop involving cortisol, and its action is increased by antidiuretic hormone (see vasopressin) and *angiotensin II. It can be administered intravenously as part of the CRH test, during which blood is analysed at 15-minute intervals for one hour for the ACTH response, which is excessive in cases of primary adrenal failure and suppressed in cases of anterior *hypopituitarism.... corticotrophin-releasing hormone

Cremasteric Reflex

a superficial reflex in males elicited by stroking the inner side of the upper thigh with a sharp object. If the reflex is intact the scrotum on that side is pulled upwards as the cremaster muscle contracts. Absence or reduction of both cremasteric reflexes indicates an upper *motor neuron lesion; absence of the reflex on one side suggests a lower motor neuron lesion at the level of the first lumbar spinal nerve.... cremasteric reflex

Crown–rump Length

(CRL) the longest measurement of the fetus from end to end. Measurement of the CRL of the embryo in the first trimester has been shown to be the most accurate parameter for assessment of gestational age; the measurement is less accurate at the end of the first trimester because of fetal flexion.... crown–rump length

Crude Rate

the total number of events (e.g. cases of lung cancer) expressed as a rate per 1000 population. When factors such as age structure or sex of populations can significantly affect the rates (as in *mortality or *morbidity rates) it is more meaningful to compare age/sex specific rates using one or more age groups of a designated sex (e.g. lung cancer in males aged 55–64 years). More complex calculations, which take account of the age and sex structure of a population as a whole, can produce *standardized rates and *standardized mortality ratios (SMR).... crude rate

Dna Repair

a variety of mechanisms that help to ensure that the genetic sequence, as expressed in the DNA, is maintained and that errors that occur during DNA replication, by mutation, are not allowed to accumulate. An error in the genetic sequence could cause cell death by interfering with the replication process. DNA repair involves the action of enzymes, which detect damage to DNA and effect the repair. Some genetic diseases, including *ataxia telangiectasia and *xeroderma pigmentosum, are due to deficiencies in these enzymes.... dna repair

Do Not Attempt Resuscitation Order

see DNAR order.... do not attempt resuscitation order

Eisenmenger Reaction

(Eisenmenger syndrome) a condition in which *pulmonary hypertension is associated with a *septal defect, so that blood flows from the right to the left side of the heart or from the pulmonary artery to the aorta. This allows blue blood, poor in oxygen, to bypass the lungs and enter the general circulation. This reduces the oxygen content of the arterial blood in the aorta and its branches, resulting in a patient with a dusky blue appearance (*cyanosis) and an increased number of red blood cells (*polycythaemia). There is no curative treatment at this stage, but the patient may be helped by the control of heart failure and polycythaemia. The condition may be prevented by appropriate treatment of the septal defect in early childhood before irreversible pulmonary hypertension develops. [V. Eisenmenger (1864–1932), German physician]... eisenmenger reaction

Endoplasmic Reticulum

(ER) a system of membranes present in the cytoplasm of cells. ER is described as rough when it has *ribosomes attached to its surface and smooth when ribosomes are absent.

Fractional Flow Reserve

(FFR) a technique used to quantify the severity of a coronary artery narrowing. During *cardiac catheterization, a specialized wire is passed down the coronary artery to measure pressure. The ratio of the pressure measured downstream of the narrowing to the pressure measured upstream is derived (this ratio also applies to coronary flow). When the ratio is below a certain threshold, flow restriction by the narrowing is deemed to be significant and *percutaneous coronary intervention is likely to be beneficial.... fractional flow reserve

Glp-1 Receptor Agonists

a group of drugs used in the treatment of type 2 diabetes. They mimic the actions of *glucagon-like peptide-1 in regulating the rise in blood glucose levels after eating and they also enhance satiety (see incretin). As these drugs respond to a falling blood glucose level there is a reduced tendency to *hypoglycaemia compared with *sulphonylurea drugs and insulin therapy itself. They are given by subcutaneous injection and three of them are licensed for use in the UK: exenatide (Byetta; twice daily dosing), liraglutide (Victoza; once daily dosing), and lixisenatide (Lyxumia; once daily dosing).... glp-1 receptor agonists

When syncope occurs, the device can be examined using wireless technology to reveal the heart rhythm at the time of the episode.... implantable loop recorder

Infant Mortality Rate

(IMR) the number of deaths of children under one year of age per 1000 live births in a given year. Included in the IMR are the neonatal mortality rate (calculated from deaths occurring in the first four weeks of life) and postneonatal mortality rate (from deaths occurring from four weeks). Neonatal deaths are further subdivided into early (first week) and late (second, third, and fourth weeks). In prosperous countries neonatal deaths account for about two-thirds of infant mortalities, the majority being in the first week (in the UK the major cause is prematurity and related problems). The IMR is usually regarded more as a measure of social affluence than a measure of the quality of antenatal and/or obstetric care; the latter is more truly reflected in the *perinatal mortality rate.... infant mortality rate

Insulin Resistance

diminution in the response of the body’s tissues to insulin, so that higher concentrations of serum insulin are required to maintain normal circulating glucose levels. Eventually the islet cells can no longer produce adequate amounts of insulin for effective glucose lowering, resulting in hyperglycaemia. Insulin resistance is one of the risk factors for cardiovascular disease. See also diabetes mellitus; metabolic syndrome.... insulin resistance

Intensity-modulated Radiotherapy

(IMRT) radiotherapy using multiple beams with variable intensity across each field, resulting in dose distributions that can fit to concave shapes and thus reduce dose to surrounding healthy tissues and organs.

Maternal Mortality Rate

the number of deaths due to complications of pregnancy, childbirth, and the puerperium per 100,000 live births (see also stillbirth). In 1952 concern about maternal mortality resulted in Britain in the setting up of a triennial *confidential enquiry into every such death to identify any shortfall in resources or care. The first triennial report was published in 1985. Since 2014 reports have been produced annually by MBRRACE-UK (Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries Across the UK). Levels of *maternal deaths are currently low: a report published in 2017 (covering 2013–15) counted 202 obstetric-related deaths (8.76 per 100,000 live births). Thromboembolism was the commonest direct cause of death (30 deaths, 1.13 per 100,000 live births), while heart disease was the commonest indirect cause of death (54 deaths, 2.34 per 100,000 live births).... maternal mortality rate

Mayer–rokitansky–küster–hauser Syndrome

(Rokitansky–Küster–Hauser syndrome, Müllerian agenesis) congenital absence of the uterus and upper part of the vagina due to failure of development of the *Müllerian duct. It may be associated with skeletal, renal, and auditory abnormalities, but usually presents with amenorrhoea in a patient with otherwise normal secondary sexual characteristics. There is a multidisciplinary approach to treatment, with psychological support, counselling, discussion of creation of a ‘neovagina’ with gradual use of vaginal dilators, and/or surgical vaginal reconstruction. Surrogacy is the only option for childbearing, although oocyte donation from the mother to a surrogate can be discussed. [K. W. Mayer (1795–1868), German gynaecologist; K. von Rokitansky (1804–78), Austrian pathologist; H. Küster and G. A. Hauser (20th century), German gynaecologists]... mayer–rokitansky–küster–hauser syndrome

Mental Health Review Tribunal

(MHRT) a tribunal, established under the Mental Health Act 1959 and now operating under the Mental Health Act 2007, to which applications may be made for the discharge from hospital of a person compulsorily detained there under provisions of the Act (see compulsory admission). When a patient is subject to a restriction order an application may only be made after his or her first six months of detention. The powers of the tribunal, which comprises both legally and medically qualified members, include reclassifying unrestricted patients, recommending leave of absence for a patient, delaying discharge, and transferring patients to other hospitals. Detained patients may also apply to have a managers hearing to review their detention. The powers of the managers hearing are slightly different from those of the MHRT, but both are defined in the Mental Health Act 2007 and both can discharge a patient from a section of the Mental Health Act.... mental health review tribunal

Microalbumin:creatinine Ratio

a laboratory measurement used as a screening test for the first signs of kidney damage in *diabetes mellitus.

The tensor tympani is thought to contract during chewing. The sound-evoked middle ear reflex can be detected using a *tympanometer.... middle ear reflex

Middle East Respiratory Syndrome

(MERS) a viral respiratory infection that was first identified in 2012. Humans seem to be infected most easily by contact with dromedary camels (hence the informal name camel flu), although human-to-human infection also occurs. Symptoms include fever, cough, and shortness of breath. Although the syndrome is often mild, death occurs in about a third of diagnosed cases. Most reported cases have been in the Arabian Peninsula, although there was a major outbreak in South Korea in 2015. At present there is no vaccine or treatment.... middle east respiratory syndrome

Mitral Regurgitation

(mitral incompetence) failure of the *mitral valve to close, allowing a reflux of blood from the left ventricle of the heart to the left atrium. It may be due to mitral valve prolapse (MVP) in which one or both valve leaflets flop back into the left atrium (also known as ‘floppy mitral valve’). It also results from chronic rheumatic scarring of the valve, or is secondary to left ventricular muscle damage. Its manifestations include breathlessness, atrial *fibrillation, embolism, enlargement of the left ventricle, and a systolic *murmur. Mild cases are symptomless and require no treatment, but in severe cases the affected valve should be repaired or replaced with an artificial one (mitral prosthesis).... mitral regurgitation

Modified Release

Moro Reflex

(startle reflex) a primitive reflex seen in newborn babies in response to the stimulus of a sudden noise or movement: the baby will fling its arms and legs wide and will appear to stiffen; the arms and legs are then drawn back into flexion. The Moro reflex should disappear spontaneously by four months. Its presence beyond this age is suggestive of an underlying neurological disorder, such as cerebral palsy. [E. Moro (1874–1951), German paediatrician]... moro reflex

Multiplanar Reconstruction

(MPR) a computer technique that allows images to be created, after the information has been collected (see post-processing), in any of the three named planes – *axial, *sagittal, or *coronal – or variations of these, such as oblique or curved planes. The effect is similar to allowing parts of the body to be sliced away, revealing the tissues inside so that they can be studied.... multiplanar reconstruction

Muscular Rheumatism

any aching pain in the muscles and joints. Commonly the symptoms are due to *fibrositis; wear and tear of the joints (*osteoarthritis); or to inflammation of the muscles associated with abnormal immune reactions (*polymyalgia rheumatica). Generalized muscle pain with specific tender points and fatigue is called *fibromyalgia.... muscular rheumatism

Myenteric Reflex

Myoglobinuric Acute Renal Failure

acute kidney injury caused by myoglobin that is released from damaged skeletal muscle (*rhabdomyolysis). This is usually the result of trauma and the condition was first recognized in victims trapped and crushed during the London Blitz. Muscle injury can also occur with pressure necrosis, particularly in the unconscious or immobile patient, or with a *compartment syndrome. Rarely it may complicate intensive muscular exercise or extensive viral myositis and it is a recognized complication of modest overexertion in some inherited disorders of muscle metabolism, such as *McArdle’s disease.... myoglobinuric acute renal failure

Muscle Relaxant

an agent that reduces tension in voluntary muscles. Drugs such as *baclofen, *dantrolene, and *diazepam are used to relieve skeletal muscular spasms in various spastic conditions, parkinsonism, and tetanus. The drugs used to relax voluntary muscles during the administration of anaesthetics in surgical operations act by blocking the transmission of impulses at neuromuscular junctions. Nondepolarizing muscle relaxants, e.g. *atracurium besilate, cisatracurium, pancuronium, and rocuronium, bind to receptor sites normally occupied by acetylcholine; depolarizing muscle relaxants, e.g. *suxamethonium, mimic the action of acetylcholine but *depolarization is prolonged.... muscle relaxant

Osler–rendu–weber Disease

(hereditary haemorrhagic telangiectasia) a hereditary (autosomal *dominant) disorder characterized by thinning of the blood vessel walls, resulting in abnormally wide and fragile blood vessels. Patients may develop telangiectasia (see telangiectasis), nosebleeds, and arteriovenous malformations (see angioma). It is caused by mutations in the endoglin (ENG) gene or the activin receptor-like kinase (ALK-1) gene. [Sir W. Osler (1849–1919), Canadian physician; H. J. M. Rendu (1844–1902), French physician; F. P. Weber (1863–1962), British physician]... osler–rendu–weber disease

(PERT) a therapeutic approach using supplements of the digestive enzymes lipase, amylase, and protease (Creon, Pancrex), which are given when there is insufficient endogenous production of pancreatic enzymes: for example, to patients with pancreatic cancer or cystic fibrosis. The capsules must be taken with all meals and snacks to be effective. PERT treats the symptoms of *steatorrhoea.... pancreatic enzyme replacement therapy

Parathyroid Hormone-related Protein

(PTH-RP) a protein that is secreted by certain malignant tumours and is the main cause of malignant *hypercalcaemia. PTH-RP, which has effects similar to *parathyroid hormone, stimulates generalized bone resorption and excessive calcium reabsorption in the kidney tubules. It is most commonly produced by lung tumours, squamous-cell carcinomas of other organs, melanomas, and tumours of the breast, liver, pancreas, bladder, and prostate.... parathyroid hormone-related protein

Parental Responsibility

the legal status that requires adults to act in the interests of a child’s welfare. A birth mother always has parental responsibility unless it is removed by an adoption order, as has the father if married to the birth mother or named on the birth certificate. Same-sex parents, if civil partners, both have parental responsibility. In medical ethics, a person with parental responsibility can consent to, or refuse, treatment on behalf of a child who is too young to have capacity to make his or her own decisions about health care. However, the entitlement to act on behalf of a child is limited to the extent to which a person with parental responsibility is acting in the child’s best interests. See also Gillick competence.

Patellar Reflex

(knee jerk) reflex contraction of the quadriceps (thigh) muscle so that the leg kicks, elicited in a patient sitting with one knee crossed over the other by sharply tapping the tendon of the muscle below the kneecap. The reflex is mediated through nerves emanating from the third and fourth lumbar spinal levels (see spinal nerves). This is a test of the connection between the sensory nerves attached to stretch receptors in the muscle, the spinal cord, and the motor neurons running from the cord to the thigh muscle, all of which are involved in the reflex. The patellar reflex is reduced or absent when there is disease or damage of the spinal cord at or below the level of the reflex and exaggerated in disorders above the level of the reflex.... patellar reflex

Peak Expiratory Flow Rate

(PEFR) the maximum rate at which a person can forcibly expel air from the lungs at any time, expressed usually in litres per minute (occasionally in litres per second). A low value can help diagnose asthma in the correct clinical context, and differences between the morning and evening values can also be a feature of poor control of asthma. There is a place for PEFR in the monitoring of acute exacerbations of chronic pulmonary obstructive disease (COPD) but not in the diagnosis of COPD.... peak expiratory flow rate

Peptide Receptor Radionuclide Therapy

(PRRT) a type of radiotherapy used to treat neuroendocrine tumours (NETs; see neuroendocrine system). A *radionuclide is combined with a relevant *peptide to create a so-called radiopeptide, which is injected into the patient’s bloodstream. Because NETs have an overexpression of peptide receptors, the radiopeptide binds to the tumour, delivering a high dose of radiation directly to the cancer cells. The chief merit of PRRT is this ability to target delivery of radionuclides for highly localized treatment. A similar technique, using a gamma emitter as the radionuclide, can be used for locating and imaging NETs.... peptide receptor radionuclide therapy

Perinatal Mortality Rate

(PNM) the total number of babies born dead after 24 weeks gestation (*stillbirths) and of live-born babies that die in the first week of life, regardless of gestational age at birth (early neonatal deaths), per 1000 live births and stillbirths. See infant mortality rate. See also confidential enquiries.... perinatal mortality rate

Pupillary Reflex

(light reflex) the reflex change in the size of the pupil according to the amount of light entering the eye. Bright light reaching the retina stimulates nerves of the *parasympathetic nervous system, which cause the pupil to contract. In dim light the pupil opens, due to stimulation of the *sympathetic nervous system. See also iris.... pupillary reflex

Purtscher’s Retinopathy

the administration of an estimated amount of the radioactive isotope iodine-131 as a drink in order to treat an overactive thyroid gland (see thyrotoxicosis). The iodine concentrates in the thyroid and thus delivers its beta radiation locally, with little effect on other tissues. The gland will shrink and become euthyroid over the succeeding 8–12 weeks but there is a high incidence of subsequent hypothyroidism (up to 80%), which requires lifetime treatment with thyroxine. The treatment cannot be used if there is any suspicion of pregnancy, and the patient must stay away from young children and pregnant women for around 10 days after administration. Despite these drawbacks, radioactive iodine remains a popular form of treatment for any cause of hyperthyroidism.... radioactive iodine therapy

Radioembolization

(selective internal radiation therapy; SIRT) n. an *interventional radiology technique used in liver cancers. It is similar to *transarterial chemoembolization, but instead of a chemotherapeutic agent yttrium-90 particles are injected into the liver. These emit beta radiation, which kills the cells within 2 mm of their radius. SIRT is a palliative technique.

radiofrequency ablation (RFA) the selective destruction of abnormal conducting tissue in the heart by the targeted delivery of radiofrequency energy via a catheter under X-ray and electrocardiographic guidance. It is usually curative in patients with supraventricular re-entrant tachycardia and is the treatment of choice for this condition (see supraventricular tachycardia; Wolff–Parkinson–White syndrome). It can be used for a variety of other arrhythmias with varying degrees of success. *Cryoablation is an alternative approach that uses freezing to destroy the abnormal tissue.... radioembolization

Reactive Hypoglycaemia

a condition of postprandial *hypoglycaemia, of varying severity, induced by excessive levels of insulin release from the pancreas. It can be divided into early and late forms, depending on whether the insulin release occurs less than or more than three hours after the meal. The early form is due to the rapid discharge of ingested carbohydrate from the stomach into the small bowel, immediately triggering hyperinsulinaemia. It can occur without obvious cause but is most commonly associated with upper-bowel surgery. The late form is due to a loss of the early-phase insulin response causing excessive postprandial *hyperglycaemia, which then itself triggers an exaggerated insulin response with subsequent hypoglycaemia.... reactive hypoglycaemia

Real-time Imaging

the rapid acquisition and manipulation of ultrasound information from a scanning probe by electronic circuits to enable images to be produced on TV screens almost instantaneously. The operator can place the scanning probe accurately on the region of interest in order to observe its structure and appreciate moving structures within it (see Doppler ultrasound). Using similar techniques, the instantaneous display of other imaging modalities, such as *computerized tomography scanning and *magnetic resonance imaging, can now be achieved. Real-time imaging is useful in guiding *interventional radiology procedures, for example, allowing a needle to be guided accurately as it is passed into the body. It is also useful for observing dynamic physiological activity.... real-time imaging

Respiratory Distress

severe difficulty in achieving adequate oxygenation in spite of significant efforts to breathe: it is usually associated with increased *respiratory rate and the use of *accessory muscles in the chest wall. It can occur in both obstructive and nonobstructive lung conditions. See adult respiratory distress syndrome; airway obstruction; dyspnoea; respiratory distress syndrome; stridor.

respiratory distress syndrome (RDS; hyaline membrane disease) the condition of a newborn infant in which the lungs are imperfectly expanded. Initial inflation and normal expansion of the lungs requires the presence of a substance (*surfactant) that reduces the surface tension of the air sacs (alveoli) and prevents collapse of the small airways. Without surfactant the airways collapse, leading to inefficient and ‘stiff’ lungs. The condition is most common and serious among preterm infants, in whom surfactant may be deficient. It lasts 5–10 days, with worsening on days 2–3. Breathing is rapid, laboured, and shallow, and microscopic examinations of lung tissue in fatal cases has revealed the presence of *hyalin material in the collapsed air sacs. The condition is treated by careful nursing, intravenous fluids, and oxygen, with or without positive-pressure ventilation (see noninvasive ventilation). Early surfactant replacement therapy has been shown to reduce the severity of RDS and when given prophylactically it has been demonstrated to improve clinical outcome. See also adult respiratory distress syndrome.... respiratory distress

For example, a hand-washing ritual might be treated by stopping washing while being progressively exposed to dirt. The anxiety then declines, and with it the obsessions.... response prevention

Responsibility

n. the state or position of being accountable for one’s actions and decisions. In health care, responsibility for some matters may be delegated to a less experienced clinician but overall responsibility remains with the senior. At the same time, responsibility for personal health is with the individual, an approach underlined by *dependence agencies (such as Alcoholics Anonymous). Best health care in practice acknowledges this mutuality or partnership: the physician is an expert in medicine, the patient in him- or herself. See also professionalism.... responsibility

n. 1. inability to pass urine, which is retained in the bladder. The condition may be acute and painful or chronic and painless. Acute urinary retention (AUR) can be precipitated by surgery, urinary infection, constipation, and drugs; spontaneous AUR is usually caused by enlargement of the prostate gland in men, although many other conditions may result in obstruction of bladder outflow. Retention is relieved by catheter drainage of the bladder, after which the underlying problem is dealt with. See also intermittent self-catheterization. 2. the ability to store events in memory.

Infection may be conveyed to the kidneys, causing recurrent attacks of acute *pyelonephritis and scarring of the kidneys in childhood. Children with urinary infection must be investigated for reflux by *cystoscopy; if the condition does not settle with antibiotic therapy corrective surgery must be performed.... vesicoureteric reflux

Virchow–robin Spaces

(perivascular spaces) fluid-filled spaces that form around blood vessels in the *pia mater as they penetrate deeper brain tissue. They may dilate, resulting in raised intracranial pressure. [R. Virchow (1821–1902), German pathologist]... virchow–robin spaces

Visual Reinforcement Audiometry

(visual reinforced audiometry, VRA) a behavioural test of hearing for children aged approximately 6 to 30 months in which the subject sits between two calibrated loudspeakers. A sound is generated from one loudspeaker. Children who turn towards the sound are rewarded by brief illumination of a toy adjacent to the loudspeaker. Older children can be tested with headphones, rather than using the loudspeakers, to enable each ear to be tested separately. The test can be adapted for use with older subjects who have learning disabilities.... visual reinforcement audiometry

Weil–felix Reaction

a diagnostic test for typhus. A sample of the patient’s serum is tested for the presence of antibodies against the organism Proteus vulgaris. Although this relatively harmless organism is not the cause of typhus, it possesses certain antigens in common with the causative agent of the disease and can therefore be used instead of it in laboratory tests. Typhus is suspected if antibodies are found to be present. [E. Weil (1880–1922), German physician; A. Felix (1887–1956), Czech bacteriologist]... weil–felix reaction

Chamomile, Roman

Chamaemelum nobile

FAMILY: Asteraceae (Compositae)

SYNONYMS: Anthemis nobilis, camomile, English chamomile, garden chamomile, sweet chamomile, true chamomile.

GENERAL DESCRIPTION: A small, stocky, perennial herb, up to 25 cms high, with a much branched hairy stem, half spreading or creeping. It has feathery pinnate leaves, daisy-like white flowers which are larger than those of the German chamomile. The whole plant has an applelike scent.

DISTRIBUTION: Native to southern and western Europe; naturalized in North America. Cultivated in England, Belgium, Hungary, United States, Italy and France.

OTHER SPECIES: There are a great many varieties of chamomile found throughout the world, four of which are native to the British Isles, but the only one of these used therapeutically is the Roman chamomile (C. nobile).

HERBAL/FOLK TRADITION: This herb has had a medical reputation in Europe and especially in the Mediterranean region for over 2000 years, and it is still in widespread use. It was employed by the ancient Egyptians and the Moors, and it was one of the Saxons’ nine sacred herbs, which they called ‘maythen’. It was also held to be the ‘plant’s physician’, since it promoted the health of plants nearby.

It is current in the British Herbal Pharmacopoeia for the treatment of dyspepsia, nausea, anorexia, vomiting in pregnancy, dysmenorrhoea and specifically flatulent dyspepsia associated with mental stress.

ACTIONS: Analgesic, anti-anaemic, antineuralgic, antiphlogistic, antiseptic, antispasmodic, bactericidal, carminative, cholagogue, cicatrisant, digestive, emmenagogue, febrifuge, hepatic, hypnotic, nerve sedative, stomachic, sudorific, tonic, vermifuge, vulnerary.

EXTRACTION: Essential oil by steam distillation of the flower heads.

CHARACTERISTICS: A pale blue liquid (turning yellow on keeping) with a warm, sweet, fruity-herbaceous scent. It blends well with bergamot, clary sage, oakmoss, jasmine, labdanum, neroli, rose, geranium and lavender.

PRINCIPAL CONSTITUENTS: Mainly esters of angelic and tiglic acids (approx. 85 per cent), with pinene, farnesol, nerolidol, chamazulene, pinocarvone, cineol, among others.

SAFETY DATA: Non-toxic, non-irritant; can cause dermatitis in some individuals.

AROMATHERAPY/HOME: USE See German chamomile.

OTHER USES: See German chamomile.... chamomile, roman

Rose, Damask

Rosa damascena

FAMILY: Rosaceae

SYNONYMS: Summer damask rose, Bulgarian rose, Turkish rose (Anatolian rose oil), otto of rose (oil), attar of rose (oil).

GENERAL DESCRIPTION: Small prickly shrub between 1 metre and 2 metres high, with pink, very fragrant blooms with thirty-six petals, and whitish hairy leaves. It requires a very specific soil and climate.

DISTRIBUTION: Believed to be a native of the Orient, now cultivated mainly in Bulgaria, Turkey and France. Similar types are grown in China, India and Russia; however, India produces only rose water and aytar – a mixture of rose otto and sandalwood.

OTHER SPECIES: There are many different subspecies: the Turkish variety is known simply as R. damascena. ‘Trigintipetala’ is the principal cultivar in commercial cultivation, known as the ‘Kazanlik rose’. Bulgaria also grows the white rose (R. damascena var. alba) or the musk rose (R. muscatta) which is used as a windbreak around the damask rose plantations. See also cabbage rose and the Botanical Classification section.

HERBAL/FOLK TRADITION: ‘The damask rose, on account of its fragrance, belongs to the cephalics; but the next valuable virtue that it possesses consists in its cathartic quality ... oil of roses is used by itself to cool hot inflammations or swellings, and to bind and stay fluxes of humours to sores.’.

Rose hips are still current in the British Herbal Pharmacopoeia, mainly due to their high vitamin C content (also A and B). For further general properties, see entry for cabbage rose.

ACTIONS: See cabbage rose.

EXTRACTION: 1. Essential oil or otto by water or steam distillation from the fresh petals. 2. A concrete and absolute by solvent extraction from the fresh petals.

CHARACTERISTICS: 1. A pale yellow or olive yellow liquid with a very rich, deep, sweet-floral, slightly spicy scent. 2. The absolute is a reddishorange or olive viscous liquid with a rich, sweet, spicy-floral, tenacious odour. It blends well with most oils, and is useful for ‘rounding off’ blends. The Bulgarian type is considered superior in perfumery work, but in therapeutic practice it is more a matter of differing properties between the various types of rose.

PRINCIPAL CONSTITUENTS: Mainly citronellal (34–55 per cent), geraniol and nerol (30–40 per cent), stearopten (16–22 per cent), phenyl ethanol (1.5–3 per cent) and farnesol (0.2–2 per cent), with many other trace constituents.

SAFETY DATA: Non-toxic, non-irritant, nonsensitizing.

AROMATHERAPY/HOME: USE See cabbage rose.

OTHER USES: See cabbage rose.... rose, damask

Ravensara

Ravensara aromatica

FAMILY: Lauraceae

SYNONYMS: Madagascar clove-nutmeg, aromatic ravensare, Ravensara anisata, Agatophyllum aromaticum.

GENERAL DESCRIPTION: The genus Ravensara includes many species of evergreen trees or shrubs native to Madagascar and the Comoro Islands. These evergreen trees can grow up to 30 metres tall in rainforests, usually on all type of soils. The best-known species of this genus is R. aromatica used for its essential oil. It grows to a height of about 20 metres with several buttress roots at the base, with reddish bark, dark green shiny leaves and small yellow-green flowers. The fruit, a fleshy berry, are an important food source for birds. All parts of the tree are aromatic.

DISTRIBUTION: R. aromatica is native to Madagascar and once thrived in the rainforests, but is now an endangered species due to de-forestation and over-exploitation. By the early part of this century, this species required protection as the production of the essential oil from the bark, used by the pharmaceutical industry, was particularly destructive as it required felling the trees. Only the leaves can now be used for oil production, to prevent cutting down the whole tree. There is now a conservation programme in place to protect these trees: it is therefore important to obtain the essential oil of the leaf from sustainable sources.

OTHER SPECIES: There are over 30 species of Ravensara that grow in Madagascar. The common name of the genus Ravensara is actually a latinization of the Malagasy term ravintsara which means ‘good leaves’, a term originally used by the natives to describe another species of tree. European botanists in the nineteenth century made several attempts to classify the various indigenous aromatic trees of Madagascar, but due to the similarity of the two names ‘ravintsara’ and ‘ravensara’ they came to be used almost interchangeably. The botanical confusion between these two species has continued to cause a great deal of uncertainty as to their precise origins. In fact, the essential oils derived from these two species are very different aromatically as well as in their chemical composition. However, most of so-called ‘ravensara’ oil from Madagascar, is actually produced from the Cinnamomum camphora species (even if it is said to derive from R. aromatica) so great care needs to be taken in identifying the correct source of each oil. See also entry for Ravintsara.

HERBAL/FOLK TRADITION: In Madagascar, this genus of trees is commonly called hazomanitra, meaning ‘tree that smells’, as the whole part of the plant is aromatic. Traditionally, the Malagasy people used the bark and stem as a tonic and as an antibacterial medicine. The leaves were also burnt in homes after a death to prevent the spread of disease while the anise-flavoured bark was used in the production of local rum. The oil from the Ravensara genus is referred to locally as ‘the oil that heals’ because it is used for so many different conditions. The essential oil from the bark, R. anisata (a synonym for R. aromatica) is known as ‘havozo’ and has a strong anise-like odour.

ACTIONS: Antiviral, antibacterial, antifungal, anti-infectious, antiseptic, antispasmodic, expectorant, immune-stimulant.

EXTRACTION: 1. Ravensara oil is steam distilled from the leaves of the plant. 2. The essential oil distilled from the bark is called havozo. 3. An essential oil is also extracted occasionally from the fleshy fruits or berries.

CHARACTERISTICS: 1. Ravensara oil (from the leaf) has a sweet, fresh, slightly lemony, licorice-like scent with an earthy undertone. 2. Havozo (from the bark) has a fresh, strong aniseed-like odour.

PRINCIPAL CONSTITUENTS: 1. The oil from the leaf contains relatively small amounts of methyl chavicol (estragole), myrcene, a-pinene and linalool with the main constituents being limonene (approx. 13–22 per cent) and sabinene (approx. 10–16 per cent) with very little 1,8-cineole (1.8–3.3 per cent). 2. Havozo (bark oil) has a high methyl chavicol content (up to 90 per cent).

SAFETY DATA: 1. Ravensara (R. aromatica) is generally considered a safe oil (non-toxic and non-irritant) although it is best avoided during pregnancy. 2. Havozo oil is not recommended for use in aromatherapy due to its high methyl chavicol content, as it is a suspected carcinogen. Research has shown, nevertheless this oil has potent anti-microbial properties, being active against E. coli.

Cinnamomum camphora

FAMILY: Lauraceae

SYNONYMS: Cinnamomum camphora ct. 1,8-cineole.

GENERAL DESCRIPTION: Cinnamomum camphora is a tall evergreen tropical tree characteristic of the Laurel family that grows up to 20–30 metres tall. The foliage is bright green and the leaves have a glossy, waxy appearance bearing masses of small white flowers in spring. It produces clusters of shiny black berries and has a pale bark that is very rough and fissured vertically.

DISTRIBUTION: C. camphora is native to China, Japan, and Taiwan but has been introduced to many countries throughout the world including India, Australia and the USA, where in places such as Florida it is becoming increasingly invasive and a danger to the native flora. This species is not indigenous to Madagascar and was introduced onto the island during the middle of the nineteenth century. As the plant became accustomed to the Malagasy climate it became a distinct subspecies, which in time adapted so well to the new environment, naturalizing in the central-eastern regions, that it became a very sustainable species for producing an essential oil, now called ravintsara oil. However, since it is clear there are many different sub-varieties of C. camphora in various parts of the world, it is possible that there also existed another native aromatic tree already growing in Madagascar originally known as ravintsara by the local people. According to Georges M. Halpern in The Healing Trail: Essential Oils of Madagascar, an indigenous tree of this name had been part of the Malagasy culture for many centuries and its leaves were used as a traditional folk medicine.

OTHER SPECIES: The genus Cinnamomum has approximately 250 different species, many of which yield an essential oil on distillation. Amongst the most important are C. zeylanicum (cinnamon bark and leaf oils) and C. cassia (cassia oil). The single species C. camphora itself produces a wide range of essential oils including: camphor, ho wood and leaf oil, sassafras and ravintsara. All these essential oils, although derived from the same tropical tree or botanical species, differ in their chemical profile enormously depending on the country of origin as well as the part of the plant used to extract the oil: e.g. leaf or bark.

There are at least 6 different chemotypes of C. camphora essential oil due to this factor, including the camphor, linalool, 1,8-cineole, nerolidol, safrole and borneol types. For example, C. camphora, grown in Taiwan and Japan, is known as Ho oil, and has linalool as its major constituent, whereas in India and Sri Lanka the camphor type of C. camphora remains the most important. The variety of C. camphora cultivated in Madagascar contains high levels of 1,8-cineole and no camphor. In order to avoid any confusion, it has been suggested that Ravintsara should be labelled: ‘Cinnamomum camphora ct. 1,8-cineole.’

HERBAL/FOLK TRADITION: The term Cinnamomum is derived from the Greek root kinnamon or kinnamomon meaning ‘sweet wood’. The word ravint means leaf and sara means ‘good for you’ according to the Malagasy tradition, as the local people have long appreciated the therapeutic value of its leaves which were used in folk medicine to treat digestive complaints, headaches, colds and chest infections. It has also been used for culinary applications and employed as a herbal tea. The Malagasy people themselves believe that the original Ravintsara tree is an indigenous species: a ‘cousin’ of the well-known C. camphora species, which has since been introduced.

ACTIONS: Antibacterial, anticatarrhal, antifungal, anti-infectious, antimicrobial, antirheumatic, antiviral, decongestant, cicatrisant (wound healer), expectorant, immune and neurotonic.

EXTRACTION: Steam distilled from the leaves of the plant.

CHARACTERISTICS: Fresh, woody, slightly floral, balsamic, eucalyptus-like scent. It blends well with eucalyptus, rosemary, bay, frankincense, cardamon, pine, cypress, juniper and citrus oils.

PRINCIPAL CONSTITUENTS: Ravintsara is akin to Eucalyptus globulus oil (as both are particularly effective for respiratory infections) due to its high 1,8-cineole content ranging from 45–55 per cent. Other major constituents include monoterpenes (sabinene 15 per cent, alpha-pinene and beta-pinene), sesquiterpenes (beta-carophyllene), monoterpenic alcohols (alpha-terpineol 7 per cent and terpineol) and esters (terpenyl acetate).

NOTE: Ravintsara essential oil contain at least 45 per cent 1,8-cineole compared to approximately 5 per cent found in Ravensara aromatica oil.

SAFETY DATA: Ravintsara oil is generally very well tolerated by the majority of the population, although like eucalyptus, it can cause sensitization in some individuals and should be used in moderation.

AROMATHERAPY/HOME: USE

Skin care: Shingles, herpes, verrucas, warts and athletes foot.

Circulation muscles and joints: Aching muscles and joints.

Respiratory system: Coughs, colds, influenza and other respiratory ailments such as asthma, bronchitis, sinusitis, laryngitis, otitis, tonsillitis and whooping cough.

Immune system: Viral infections especially air-borne infections.

Nervous system: Nervous debility

OTHER USES: Ravintsara oil is produced in a ‘pharmaceutical grade’ for the chemical and perfumery industry.... ravintsara

Rose, Cabbage

Rosa centifolia

FAMILY: Rosaceae

SYNONYMS: Rose maroc, French rose, Provence rose, hundred-leaved rose, Moroccan otto of rose (oil), French otto of rose (oil), rose de mai (absolute or concrete).

GENERAL DESCRIPTION: The rose which is generally used for oil production is strictly a hybrid between R. centifolia, a pink rose, and R. gallica, a dark red rose. This variety, known as rose de mai, grows to a height of 2.5 metres and produces an abundance of flowers with large pink or rosy-purple petals. There are two subspecies – one is more spiny than the other.

DISTRIBUTION: The birthplace of the cultivated rose is believed to be ancient Persia; now cultivated mainly in Morocco, Tunisia, Italy, France, Yugoslavia and China. The concrete, absolute and oil are mainly produced in Morocco; the absolute in France, Italy and China.

OTHER SPECIES: There are over 10,000 types of cultivated rose! There are several subspecies of R. centifolia, depending on the country of origin. Other therapeutic species are the red rose or apothecary rose (R. gallica) of traditional Western medicine, the oriental or tea rose (R. indica), the Chinese or Japanese rose (R. rugosa) and the Turkish or Bulgarian rose (R. damascena) which is also extensively cultivated for its oil. Recently rosehip seed oil from R. rubiginosa has been found to be a very effective skin treatment; it promotes tissue regeneration and is good for scars, burns and wrinkles. The wild rose (Eubatus rubus) is now also being used to produce a rare absolute with a rich, spicy-earthy fragrance. See also entry on damask rose and the Botanical Classification section.

HERBAL/FOLK TRADITION: The healing virtues of the rose have been known since antiquity and although roses are rarely used in herbal practice nowadays, up to the Middle Ages they played an essential part in the materia medica, and still

fulfil an important role in Eastern medicine. They were used for a wide range of disorders, including digestive and menstrual problems, headaches and nervous tension, liver congestion, poor circulation, fever (plague), eye infections and skin complaints. ‘The symbolism connected with the rose is perhaps one of the richest and most complex associated with any plant ... traditionally associated with Venus, the Goddess of love and beauty, and in our materialistic age the Goddess is certainly alive and well in the cosmetics industry for rose oil (mainly synthetic) is found as a component in 46% of men’s perfumes and 98% of women’s fragrances.’.

The French or Moroccan rose possesses narcotic properties and has the reputation for being aphrodisiac (more so than the Bulgarian type), possibly due to the high percentage of phenyl ethanol in the former. For further distinctions between the different properties of rose types, see damask rose.

ACTIONS: Antidepressant, antiphlogistic, antiseptic, antispasmodic, anti-tubercular agent, antiviral, aphrodisiac, astringent, bactericidal, choleretic, cicitrisant, depurative, emmenagogue, haemostatic, hepatic, laxative, regulator of appetite, sedative (nervous), stomachic, tonic (heart, liver, stomach, uterus).

EXTRACTION: 1. Essential oil or otto by water or steam distillation from the fresh petals. (Rose water is produced as a byproduct of this process.) 2. Concrete and absolute by solvent extraction from the fresh petals. (A rose leaf absolute is also produced in small quantities in France.)

CHARACTERISTICS: 1. The oil is a pale yellow liquid with a deep, sweet, rosy-floral, tenacious odour. 2. The absolute is a reddish orange viscous liquid with a deep, rich, sweet, rosy-spicy, honeylike fragrance. It blends well with jasmine, cassie, mimosa, neroli, geranium, bergamot, lavender, clary sage, sandalwood, guaiacwood, patchouli, benzoin, chamomile, Peru balsam, clove and palmarosa.

PRINCIPAL CONSTITUENTS: It has over 300 constituents, some in minute traces. Mainly citronellol (18–22 per cent), phenyl ethanol (63 per cent), geraniol and nerol (10–15 per cent), stearopten (8 per cent), farnesol (0.2–2 per cent), among others.

SAFETY DATA: Non-toxic, non-irritant, non-sensitizing.

AROMATHERAPY/HOME: USE

Skin care: Broken capillaries, conjunctivitis (rose water), dry skin, eczema, herpes, mature and sensitive complexions, wrinkles.

Circulation muscles and joints: Palpitations, poor circulation.

Respiratory system: Asthma, coughs, hay fever.

Digestive system: Cholecystitis, liver congestion, nausea.

Genito-urinary system: Irregular menstruation, leucorrhoea, menorrhagia, uterine disorders.

Nervous system: Depression, impotence, insomnia, frigidity, headache, nervous tension and stress-related complaints – ‘But the rose procures us one thing above all: a feeling of well being, even of happiness, and the individual under its influence will develop an amiable tolerance.’.

OTHER USES: Rose water is used as a household cosmetic and culinary article (especially in Persian cookery). The concrete, absolute and oil are employed extensively in soaps, cosmetics, toiletries and perfumes of all types – floral, oriental, chypres, etc. Some flavouring uses, especially fruit products and tobacco.... rose, cabbage

Rosewood

Aniba rosaeodora

FAMILY: Lauraceae

SYNONYMS: A. rosaeodora var. amazonica, bois de rose, Brazilian rosewood.

GENERAL DESCRIPTION: Medium-sized, tropical, evergreen tree with a reddish bark and heartwood, bearing yellow flowers. Used extensively for timber. NB: This is one of the trees that is being extensively felled in the clearing of the South American rainforests; the continual production of rosewood oil is consequently enviromentally damaging.

DISTRIBUTION: Native to the Amazon region; Brazil and Peru are the main producers.

OTHER SPECIES: There are several species of timber all known as rosewood; however, the essential oil is only distilled from the above species. French Guiana used to produce the cayenne rosewood (Ocotea caudata), which is superior in quality to the Peruvian or Brazilian type.

HERBAL/FOLK TRADITION: Used for building, carving and French cabinet making. Nowadays, most rosewood goes to Japan for the production of chopsticks.

ACTIONS: Mildly analgesic, anticonvulsant, antidepressant, antimicrobial, antiseptic, aphrodisiac, bactericidal, cellular stimulant, cephalic, deodorant, stimulant (immune system), tissue regenerator, tonic.

EXTRACTION: Essential oil by steam distillation of the wood chippings.

CHARACTERISTICS: Colourless to pale yellow liquid with a very sweet, woody-floral fragrance with a spicy hint. Blends well with most oils, especially citrus, woods and florals. It helps give body and rounds off sharp edges.

PRINCIPAL CONSTITUENTS: Linalol (90–97 per cent) in cayenne rosewood; in the Brazilian oil slightly less (80–90 per cent). Also cineol, terpineol, geraniol, citronella!, limonene, pinene, among others.

SAFETY DATA: Non-toxic, non-irritant, nonsensitizing.

AROMATHERAPY/HOME: USE

Skin care: Acne, dermatitis, scars, wounds, wrinkles and general skin care: sensitive, dry, dull, combination oily/dry, etc. ‘Although it does not have any dramatic curative power ... I find it very useful especially for skin care. It is very mild and safe to use.’.

Immune system: Colds, coughs, fever, infections, stimulates the immune system.

Nervous system: Frigidity, headaches, nausea, nervous tension and stress-related conditions.

OTHER USES: Once extensively used as a source of naturallinalol, now increasingly replaced by the synthetic form. Acetylated rosewood oil is used extensively in perfumery work – soaps, toiletries, cosmetics and perfumes. The oil is employed in most major food categories, alcoholic and soft drinks.... rosewood
