Sodium valproate has widespread metabolic effects and may have dose-related side-effects. There has been concern over severe hepatic or pancreatic toxicity, but such adverse effects are rare. Other adverse effects include digestive upsets, drowsiness, muscle incoordination and skin rashes. Rare reports have been given of behavioural disturbances, with occasional aggression. Initiation and withdrawal of treatment should always be slow. Patients should reduce their alcohol intake; any other drugs they are taking that are metabolised by the liver should be carefully monitored.... sodium valproate

(2) The process by which air is puri?ed and circulated in domestic, occupational, industrial, and other settings. Ideally, the air we breathe should be of the right temperature and humidity, and free of dust, smoke, pollen, and other contaminants. Ventilation aims to produce such an atmosphere. Air-conditioning is frequently used in hospitals, o?ces, and other

public places. Special ?lters may be used to reduce the risk of airborne infections and allergies (see ALLERGY), but poorly maintained and contaminated systems may result in outbreaks of serious disorders, such as LEGIONNAIRE’S DISEASE. Sterilisation of air is rarely required, but ultraviolet light is sometimes used to kill pathogenic organisms. (See also ASTHMA; BRONCHITIS; HUMIDIFICATION.)... ventilation

Most experiments are carried out on specially bred mice and rats. Fewer than 1 per cent are done on cats, dogs, non-human primates, farm animals, frogs, ?sh and birds. Control on experiments has recently been strengthened.

The great majority of animal experiments are done without anaesthesia because feeding experiments, taking blood, or giving injections does not require anaesthetics in animals any more than in humans. Universities in Britain are responsible for fewer than one-?fth of animal experiments; commercial concerns and government institutions are responsible for most of the rest. Tests on cosmetics account for under 1 per cent of all animal work, but are necessary because such materials are often applied with great frequency – and for a long time – to the skin of adults and infants.

The use of tissue cultures and computer models instead of live animals are methods of research and investigation that are being increasingly used. There is, however, a limit to the extent to which infection, cancer, or drugs can be investigated on cultures of tissue cells. Computerised or mathematical modelling of experiments is probably the most promising line of development.... vivisection

Causes Vomiting is brought about by stimulation of this nervous centre, and in most cases this is e?ected through sensations derived from the stomach itself. Thus, of the drugs which cause vomiting, some act only after being absorbed into the blood and carried to the brain, although most are irritants to the mucous membrane of the stomach (see EMETICS); various diseases of the stomach, such as cancer, ulcer and food poisoning act in a similar way. Stimulation – not only of the nerves of the stomach, but also of those supplying other abdominal organs – produces vomiting; thus in obstruction of the bowels, peritonitis, gall-stone colic, renal colic, and even in some women during pregnancy, vomiting is a prominent symptom.

Severe emotional shock may cause vomiting, as may acute anxiety and unpleasant experiences such as seeing an accident, suffering severe pain or travel sickness.

Direct disturbance of the brain itself is a cause: for example, a blow on the head, a cerebral tumour, a cerebral abscess, meningitis. Nausea and vomiting are common symptoms that may arise from local disease of the gastrointestinal tract, but they are also associated with systemic illness – for example, DIABETES MELLITUS or kidney failure (see KIDNEYS, DISEASES OF) – and also with disturbances of labyrinthine function, such as motion sickness and acute labyrinthitis.

Treatment The cause of the vomiting must be sought and treatment directed towards this. Symptomatic treatment for vomiting can be dangerous since accurate diagnosis of the cause may be hindered. If antinauseant drug treatment is indicated, the choice of drug depends on the cause of the vomiting.

Granisetron and ondansetron are 5hydroxytryptamine (5HT3) antagonists valuable in the treatment of nausea and vomiting induced by cytotoxic CHEMOTHERAPY or RADIOTHERAPY and prevention and treatment of post-operative nausea and vomiting. Prochlorperazine is valuable in the treatment of severe nausea, vomiting, VERTIGO and disorders of the LABYRINTH of the EAR, although extrapyramidal symptoms may occur, particularly in children, elderly and debilitated patients.

Vomiting may occur after surgical operations and this is due to the combined effects of analgesics, anaesthetic agents and the psychological stress of operation. Various drugs can be used to prevent or stop post-operative vomiting.

Nausea and vomiting are common symptoms in pregnancy. Drugs are best avoided in this situation as they may damage the developing FETUS. Simple measures, such as the taking of food before getting up in the morning and reassurance, are often all that is necessary.... vomiting

A researcher has suggested a link between the vaccine and AUTISM, but massive studies of children with and without this condition in several countries have failed to ?nd any evidence to back the claim. Nonetheless, the publicity war has been largely lost by the UK health departments so that vaccine rates have dropped to a worryingly low level.

In cases of prolongation of the ?rst stage of labour, the ventouse may be used to accelerate dilatation of the cervix – provided that the cervix is already su?ciently dilated to allow application of the cup. The ventouse cannot be applied to the breech or face; in urgent cases of fetal distress the operation takes too long, and forceps delivery is preferred. There is some doubt about its safety when used on premature babies; many obstetricians feel that forceps delivery reduces the risk of intracranial haemorrhage. The vacuum extractor, while resulting in a slower delivery than when forceps are used, has a lower risk of damage to the mother’s birth canal.

Pathway of light from the eye to the brain Light enters the EYE by passing through the transparent cornea, then through the aqueous humour ?lling the anterior chamber. It then passes through the pupil, through the lens and the vitreous to reach the retina. In the retina, the rod and cone photoreceptors detect light and relay messages in the form of electrochemical impulses through the various layers of the retina to the nerve ?bres. The nerve ?bres carry messages via the optic nerve, optic chiasma, optic tract, lateral geniculate body and ?nally the optic radiations to the visual cortex.

Here in the visual cortex these messages are interpreted. It is therefore the visual cortex of the BRAIN that ‘sees’.

Visual acuity Two points will not be seen as two unless they are separated by a minimum distance. This distance is such that the objects are so far apart that the lines joining them to the eye enclose between them (subtend) an angle of at least one minute of a degree. This amount of separation allows the images of the two points to fall on two separate cones (if the light from two points falls on one cone, the two points would be seen as a single point). There are many tests of visual acuity. One of the more common is the Snellen test type. This is made up of many letters of di?erent size. By conventions the chart is placed 6 metres away from the patient. Someone able to see the lowest line at this distance has a visual acuity of 6/4. If they are only able to see the top letter they have 6/60 vision. ‘Normal’ vision is 6/6.

Colour vision ‘White light’ is made up of component colours. These can be separated by a prism, thereby producing a spectrum. The three cardinal colours are red, green, and blue; all other colours can be produced by a varying mixture of these three. Colour vision is a complex subject. The trichromat theory of colour vision suggests that there are three types of cones, each type sensitive to one of the cardinal colours. Colour perception is based on di?erential stimulation of these cone types. The opponent colour theory suggests that each cone type can generate signals of the opposite kind. Output from some cones can collaborate with the output from others or can inhibit the action of other cones. Colour perception results from these various complex interactions.

Defective colour vision may be hereditary or acquired, and can occur in the presence of normal visual acuity. HEREDITARY DEFECTIVE COLOUR VISION is more common in men (7 per cent of males) than women (0·5 per cent of females). Men are affected, but women convey the abnormal gene (see GENES) to their children. It occurs because one or more of the photopigments of the retina are abnormal, or the cones are damaged. Red-green colour defect is the most common. ACQUIRED DEFECTIVE COLOUR VISION is the result of disease of the cones or their connections in the retina, optic nerve or brain – for example, macular disease, optic neuritis. Col-our vision can be impaired but not lost as a result of corneal opaci?cation or cataract formation (see under EYE, DISORDERS OF).

TESTS OF COLOUR VISION These use specially designed numbers made of coloured dots surrounded by dots of confusing colour (e.g. plates).... vision

The woman is given a course of fertility drugs to stimulate release of eggs from the ovary. This is followed by ultrasound scanning to check the eggs, which are collected by laparoscopy immediately before ovulation. They are then mixed with sperm in the laboratory. Two, or sometimes more, fertilized eggs are replaced into the uterus. If they become safely implanted in the uterine wall, the pregnancy usually continues normally.

Only about 1 in 10 couples undergoing in vitro fertilization achieves pregnancy at the 1st attempt, and many attempts may be needed before a successful pregnancy is achieved. Modifications of the technique, such as gamete intrafallopian transfer (GIFT), are simpler and cheaper than the original method. in vivo Biological processes occurring within the body. (See also in vitro.)... in vitro fertilization

Varices develop as a consequence of portal hypertension.

Blood in the portal vein, passing from the intestines to the liver, meets resistance due to liver disease.

The increased blood pressure causes blood to be diverted into small veins in the walls of the oesophagus and stomach.

These veins may become distended and rupture, causing vomiting of blood and black faeces.

There are usually other symptoms of chronic liver disease.

To control acute bleeding, a balloon catheter may be passed into the oesophagus to press on the bleeding varices.

The varices may be treated with an intravenous injection of vasopressin and/or by injection, via an endoscope, of a sclerosant that seals off the affected veins.... oesophageal varices

Varices is the plural of varix.

Partial loss of the visual field may occur in glaucoma or stroke.... visual field

Vitamin A is absorbed by the body in the form of retinol. This is found in liver, fish-liver oils, egg yolk, dairy produce, and is added to margarines. Carotene, which the body converts into retinol, is found in various vegetables and fruits.

Vitamin A deficiency is rare in developed countries. In most cases, it is due to malabsorption. Vitamin A deficiency may also result from long-term treatment with certain lipid-lowering drugs. Deficiency is common in some developing countries due to poor diet. The first symptom of deficiency is night blindness, followed by dryness and inflammation of the eyes (see xerophthalmia), keratomalacia, and eventually blindness. Deficiency also causes reduced resistance to infection, dry skin, and, in children, stunted growth.

Prolonged excessive intake of vitamin A can cause headache, nausea, loss of appetite, skin peeling, hair loss, and irregular menstruation. In severe cases, the liver and spleen become enlarged. Excessive intake during pregnancy may cause birth defects. In infants, excessive intake may cause skull deformities, which disappear if the diet is corrected.

The drug tretinoin (a derivative of vitamin A) is used to treat severe acne.... vitamin a

The main dietary sources are fruits and vegetables. Considerable amounts of vitamin C are lost when foods are processed, cooked, or kept warm.

Mild deficiency of vitamin C may result from a serious injury or burn, major surgery, the use of oral contraceptives, fever, or continual inhalation of carbon monoxide (from traffic fumes or tobacco smoke). It may cause weakness, general aches, swollen gums, and nosebleeds. More serious deficiency is usually caused by a very restricted diet. Severe deficiency leads to scurvy and anaemia.

If the daily dose of vitamin C exceeds about 1g, it may cause nausea, stomach cramps, diarrhoea, or kidney stones

(see calculi, urinary tract).... vitamin c

Good sources include oily fish, liver, and egg yolk; vitamin D is also added to margarines. In the body, vitamin D is synthesized by the action of ultraviolet light on a particular chemical in the skin.

Deficiency may occur in people with a poor diet, in premature infants, and in those deprived of sunlight. It can also result from malabsorption. Other causes include liver or kidney disorders and some genetic defects. Prolonged use of certain drugs, such as phenytoin, may also lead to deficiency. Deficiency in young children causes rickets; long-term deficiency in adults leads to osteomalacia.Excessive intake of vitamin D may lead to hypercalcaemia and abnormal calcium deposits in the soft tissues, kidneys, and blood vessel walls.

In children, it may cause growth retardation.... vitamin d

Dietary deficiency is rare; deficiency is most common in people with malabsorption, certain liver disorders, and in premature infants. It leads to the destruction of red blood cells, which eventually leads to anaemia. In infants, deficiency causes irritability and oedema.

Prolonged excessive intake of vitamin E may cause abdominal pain, nausea, and diarrhoea.

It may also reduce intestinal absorption of vitamins A, D, and K.... vitamin e

Dietary deficiency rarely occurs.

Deficiency may develop in people with malabsorption, certain liver disorders, or chronic diarrhoea.

It may also result from prolonged treatment with antibiotics.

Newborns lack the intestinal bacteria that produce vitamin K and are routinely given supplements to prevent deficiency.

Vitamin K deficiency may cause nosebleeds and bleeding from the gums, intestine, and urinary tract.

In rare, severe cases, brain haemorrhage may result.

Excessive intake of vitamin K is not known to cause harmful effects.... vitamin k

Treatment depends on the cause. A combination of drugs applied to the vulva and good hygiene is usually recommended. A biopsy may be taken, if there are skin changes, to exclude the slight possibility of vulval cancer. (See also vulvovaginitis; vaginitis.)... vulvitis

walking Movement of the body by lifting the feet alternately and bringing 1 foot into contact with the ground before the other starts to leave it. A person’s gait is determined by body shape, size, and posture. The age at which children first walk varies enormously.

Walking is controlled by nerve signals from the brain’s motor cortex (see cerebrum), basal ganglia, and cerebellum that travel via the spinal cord to the muscles. Abnormal gait may be caused by joint stiffness, muscle weakness (sometimes due to conditions such as poliomyelitis or muscular dystrophy), or skeletal abnormalities (see, for example, talipes; hip, congenital dislocation of; scoliosis; bone tumour; arthritis). Children may develop knock-knee or bowleg; synovitis of the hip and Perthes’ disease are also common. Adolescents may develop a painful limp due to a slipped epiphysis (see femoral epiphysis, slipped) or to fracture or disease of the tibia, fibula or femur.

Abnormal gait may also be the result of neurological disorders such as stroke (commonly resulting in hemiplegia), parkinsonism, peripheral neuritis, multiple sclerosis, various forms of myelitis, and chorea.

Ménière’s disease may cause severe loss of balance and instability.... vulvovaginitis

For a diagnosis of PVS to be made, the state should have continued for more than a prede?ned period, usually one month. Half of patients die within 2–6 months, but some can survive for longer with arti?cial feeding. To assess a person’s level of consciousness, a numerical marking system rated according to various functions – eye opening, motor and verbal responses – has been established called the GLASGOW COMA SCALE.

The ETHICS of keeping patients alive with arti?cial support are controversial. In the UK, a legal ruling is usually needed for arti?cial support to be withdrawn after a diagnosis of PVS has been made. The chances of regaining consciousness after one year are slim and, even if patients do recover, they are usually left with severe neurological disability.

PVS must be distinguished from conditions which appear similar. These include the ‘LOCKED-IN SYNDROME’ which is the result of damage to the brain stem (see BRAIN). Patients with this syndrome are conscious but unable to speak or move except for certain eye movements and blinking. The psychiatric state of CATATONIA is another condition in which the patient retains consciousness and will usually recover.... persistent vegetative state (pvs)

Valsalva’s manoeuvre is involuntarily performed when a person strains to open his or her bowels: in these circumstances the passage of air to the lungs is blocked by instinctive closure of the vocal cords in the LARYNX. The resultant raised abdominal pressure helps to expel the bowel contents. The manoeuvre is also used in the study of cardiovascular physiology because the rise in pressure in the chest restricts the return of venous blood to the right atrium of the HEART. Pressure in the peripheral VEINS is raised and the amount of blood entering and leaving the heart falls. This drop in cardiac output may cause the subject to faint because the supply of oxygenated blood to the brain is reduced.... valsalva’s manoeuvre

TUBERCULIN PURIFIED PROTEIN DERIVATIVE (TUBERCULIN PPD) is the active principle of OT (see above), and is prepared from the ?uid medium on which the Mycobacterium tuberculosis has been grown. It is supplied as a liquid, a powder, or as sterile tablets. The liquid contains 100,000 units per millilitre, and the dry powder contains 30,000 units per milligram. It is distributed in sterile containers sealed so as to exclude micro-organisms. It is more constant in composition and potency than OT.

Uses The basis of the tuberculin reaction is that any person who has been infected with the Mycobacterium tuberculosis gives a reaction when a small amount of tuberculin is injected into the skin. A negative reaction means either that the individual has never been infected with the tubercle bacillus, or that the infection has been too recent to have allowed of sensitivity developing.

There are various methods of carrying out the test, of which the following are the most commonly used. The Mantoux test is the most satisfactory of all, and has the advantage that the size of the reaction is a guide to the severity of the tuberculous infection: it is performed by injecting the tuberculin into the skin on the forearm. The Heaf multiple puncture test is reliable: it is carried out with the multiple puncture apparatus, or Heaf gun. The Vollmer patch test, using an impregnated ?lter paper, is useful in children because of the ease with which it can be carried out.... varieties

Structure While of similar structure to an artery, veins have much thinner walls, with much less muscular tissue. Furthermore, most veins have one-way VALVES to ensure that the blood ?ows in the right direction. These are most numerous in the legs, then the arms, with few in the internal organs.

Chief veins Four pulmonary veins open into the left atrium of the heart, two from each lung. The superior vena cava returns the blood from the head, neck, and arms; while the inferior vena cava returns blood from the legs and abdomen. The large basilic vein that runs up the inner side of the upper arm is the vein usually opened in blood-letting (see VENESECTION). The great saphenous vein is of special interest, because of its liability to become distended or varicose. Within the abdomen, the inferior vena cava receives branches corresponding to several branches of the aorta, its largest branches being the hepatic veins, which return not only the blood that has reached the liver in the hepatic arteries, but also blood which comes from the digestive organs in the PORTAL VEIN to undergo a second capillary circulation in the liver.

There are several connections between the superior and inferior cava, the most important being three azygos veins that lie upon the sides of the spinal column, the veins on the front of the abdomen, and some veins that emerge from the abdomen at the navel and connect the portal system with those of the inferior and superior vena cava.

Varicose veins are dilated tortuous veins occurring in about 15 per cent of adults – women more than men. They most commonly occur in the legs but may also occur in the anal canal (HAEMORRHOIDS) and in the oesophagus (due to liver disease).

Normally blood ?ows from the subcutaneous tissues to the super?cial veins which drain via perforating veins into the deep veins of the leg. This ?ow, back towards the heart, is aided by valves within the veins. When these valves fail, increased pressure is exerted on the blood vessels leading to dilatations known as varicose veins.

Treatment is needed to prevent complications such as ulceration and bleeding, or for

cosmetic purposes. Treatment alternatives include injection with sclerosing agents to obliterate the lumen of the veins (sclerotherapy), or surgery; in the elderly or un?t, an elastic stocking may su?ce. One operation is the Trendelenburg operation in which the saphenous vein is disconnected from the femoral vein and individual varicose veins are avulsed. (See also VASCULITIS.)

Thrombosis Thrombosis occurs when blood, which is normally a liquid, clots within the vein to form a semisolid thrombus (clot). This occurs through a combination of reduced blood ?ow and hypercoagulability (a reduced threshold for clotting). The most common site for this to occur is in the deep veins of the leg, where it is known as a deep-vein thrombosis (DVT).

Predisposing factors include immobility (leading to reduced blood ?ow), such as during long journeys (e.g. plane ?ights) where there is little opportunity to stretch one’s legs; surgery (leading to temporary post-operative immobility and hypercoagulability of blood); oestrogen administration (low-dose oestrogen oral contraceptives carry a very low relative risk); and several medical illnesses such as heart failure, stroke and malignancy.

Deep-vein thrombosis presents as a tender, warm, red swelling of the calf. Diagnosis may be con?rmed by venogram (an X-ray taken following injection of contrast medium into the foot veins) or by ultrasound scanning looking for ?ow within the veins.

Prevention is important. This is why patients are mobilised and/or given leg exercises very soon after an operation, even major surgery. People should avoid sitting for long periods, particularly if the edge of the seat is hard, thus impeding venous return from the legs. Car drivers should stop regularly on a long journey and walk around; airline travellers should, where possible, walk round the aisle(s) and also exercise and massage their leg muscles, as well as drinking ample non-alcoholic ?uids.

Diagnosis and treatment are important because there is a risk that the clotted blood within the vein becomes dislodged and travels up the venous system to become lodged in the pulmonary arteries. This is known as PULMONARY EMBOLISM.

Treatment is directed at thinning the blood with ANTICOAGULANTS, initially with heparin and subsequently with WARFARIN for a period of time while the clot resolves.

Blocked super?cial veins are described as super?cial thrombophlebitis, which produces in?ammation over the vein. It responds to antiin?ammatory analgesics. Occasionally heparin and ANTIBIOTICS are required to treat associated thrombosis and infection.... veins, diseases of

Voice This has three varying characteristics: loudness, pitch, and quality or timbre. Loudness depends on the volume of air available and therefore on the size of the chest and the strength of its muscles. Pitch is determined by larynx size, the degree of tenseness at which the vocal cords are maintained, and whether the cords vibrate as a whole or merely at their edges.

In any given voice, the range of pitch seldom exceeds two and a half octaves. Typically, the small larynx of childhood produces a shrill or treble voice; the rapid growth of the larynx around PUBERTY causes the voice to ‘break’ in boys. Changes in the voice also occur at other ages as a result of the secondary action of the SEX HORMONES. Generally speaking, the adult voice is bass and tenor in men, contralto or soprano in women. Timbre is due to di?erences in the larynx, as well as to voluntary changes in the shape of the mouth.

Speech Rapid modi?cations of the voice, produced by movements of the PALATE, tongue and lips. Infants hear the sounds made by others and mimic them; hence the speech centres in the BRAIN are closely connected with those of hearing.

Defects of speech See below, and also SPEECH DISORDERS. MUTISM, or absence of the power to speak, may be due to various causes. LEARNING DISABILITY that prevents the child from mimicking the actions of others is most common; in other cases the child has normal intelligence but some neurological disorder, or disorder of the speech organs, is responsible. Alternatively, complete DEAFNESS or early childhood ear disease may be the cause. STAMMERING is a highly individual condition, but is basically a lack of coordination between the di?erent parts of the speech mechanism. (See also main entry on STAMMERING.) DYSPHASIA is the inability to speak or understand speech, most commonly following brain disease, such as STROKE. APHONIA or loss of voice may be caused by LARYNGITIS or, rarely, a symptom of conversion and dissociative mental disorders – traditionally referred to as HYSTERIA. It is generally of short duration.... voice and speech

Haemophilus vaccine (HiB) This vaccine was introduced in the UK in 1994 to deal with the annual incidence of about 1,500 cases and 100 deaths from haemophilus MENINGITIS, SEPTICAEMIA and EPIGLOTTITIS, mostly in pre-school children. It has been remarkably successful when given as part of the primary vaccination programme at two, three and four months of age – reducing the incidence by over 95 per cent. A few cases still occur, either due to other subgroups of the organism for which the vaccine is not designed, or because of inadequate response by the child, possibly related to interference from the newer forms of pertussis vaccine (see above) given at the same time.

Meningococcal C vaccine Used in the UK from 1998, this has dramatically reduced the incidence of meningitis and septicaemia due to this organism. Used as part of the primary programme in early infancy, it does not protect against other types of meningococci.

Varicella vaccine This vaccine, used to protect against varicella (CHICKENPOX) is used in a number of countries including the United States and Japan. It has not been introduced into the UK, largely because of concerns that use in infancy would result in an upsurge in cases in adult life, when the disease may be more severe.

Pneumococcal vaccine The pneumococcus is responsible for severe and sometimes fatal childhood diseases including meningitis and septicaemia, as well as PNEUMONIA and other respiratory infections. Vaccines are available but do not protect against all strains and are reserved for special situations – such as for patients without a SPLEEN or those who are immunode?cient.... yellow fever vaccine is prepared from

Greater incidence of the condition is found in women. By interfering with the hormone balance The Pill raises the female body to a constant state of false pregnancy. This affects the character of vaginal secretions and favours growth of fungi. Oestrogens in contraceptive pills create a tissue climate conducive to Candida. Vaginal deodorants and scented soaps irritate. Because of its effect upon the Fallopian tubes it is a common cause of infertility.

Failure of the left ventricle may occur in cases of pericarditis, disease of the aortic valve, nephritis or high blood pressure.

Left ventricular failure is often of sudden onset, urgent, and may manifest as “cardiac asthma”.

Causes: blood clot, anaemia, thyroid disorder, coronary disease, congenital effects, drug therapy (beta blockers, etc), and to fevers that make heavy demands on the left ventricle.

Symptoms: breathlessness, wheezing, sweating, unproductive cough, faintness, bleeding from the lungs, palpitation. Cardiac asthma at night: feels he needs air; better upright than lying flat. Exertion soon tires. Sensation as if heart would stop. Blueness of lips and ears from hold-up in circulation of the blood through the lungs. Frequent chest colds. Awakes gasping for breath. Always tired. Cold hands and feet. Symptoms abate as compensation takes place. ‘Cream and roses’ complexion. The failure of left ventricle soon drags into failure of the right ventricle.

Right ventricular failure leads to congestive heart failure, with raised venous pressure in neck veins and body generally, causing oedema, ascites and liver engorgement.

Treatment. Agents to strengthen, support, and eliminate excess fluids from the body. BHP (1983) advises four main remedies: Hawthorn, Motherwort, Broom and Lily of the Valley. The latter works in a digitaloid manner, strengthening the heart, contracting the vessels, and lessening congestion in the lungs. Tinctures. Hawthorn 2; Stone root 1. Lily of the Valley 1. Dose: 15-45 drops thrice daily.

Broom tea. 2 teaspoons flowers, or 2-3 teaspoons tops and flowers, in cup water brought to boil and simmered one minute. 1 cup freely.

To remove fluid retention in the lungs, diuretics are indicated; chief among which is Dandelion root because of its high potassium content to prevent hypokalaemia. Dandelion coffee. As urinary excretion increases, patient improves.

Vitamin E. Not to be taken in left ventricular disorders.

Diet. See entry: DIET – HEART AND CIRCULATION.

UK Research. Researchers found that left ventricular failure was reduced by a quarter when patients were given magnesium intravenously for the first 24 hours after admission to the coronary care unit. They conclude that it should be given before any other heart therapy is commenced, and that patients should receive regular infusions if no other drug treatment is used. (The Lancet, 2.4.1994). This supports the use of magnesium sulphate (Epsom’s salts) by a past generation of herbal practitioners for the condition. ... heart – left ventricular failure (lvf)

Five viruses that attack the liver as their primary target have been identified.

They cause hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E.... hepatitis, viral

Mitral disease leads to heart failure either by a narrowing of the orifice (stenosis) or a regurgitation blocks the passage of blood from the left atrium (auricle) to the left ventricle. The left atrium enlarges (hypertrophies) in an effort to counter the impediment. Real compensation – increased thrust of the blood – is provided by the right ventricle. In order to overcome a mitral impediment the right ventricle has to enlarge.

Sooner or later the right ventricle cannot enlarge any further and general heart failure sets in. Though caused primarily by a lesion of the mitral valve, it may be secondary to left ventricular failure (LVF), thyroid disorder (thyrotoxicosis), pericarditis, congenital heart disease, or any disease which weakens ventricular muscle.

Venous congestion and back pressure of RVF leads to congestion and accumulation of fluid in the lungs, cough and spitting of blood, painful swelling of the liver, nausea, loss of appetite and severe wasting.

Where the right ventricle fails to move the blood forward as it arrives from the systemic circulation, generalised dropsy sets in. Congestion of the kidneys leads to reduced urinary excretion and presence of albumin in the urine.

The picture is well known to the cardiac practitioner: blueness of the skin, congestion of the brain circulation with sleeplessness and delirium. Soon the tension of water-logged tissues results in pain and extreme anxiety. Feet are swollen and ankles pit on pressure; chest cavities fill with fluid and the abdomen swells (ascites).

Alternatives. Cardio-tonics would be given to strengthen the ventricle and diuretics to correct fluid retention: Lily of the Valley, Hawthorn, Motherwort, Broom. BHP (1983).

Due to rheumatic fever: Hawthorn.

between about 400 and 700 nanometres. Different wavelengths produce sensations of violet, indigo, blue, green, yellow, orange, and red when they fall on the retina and stimulate nerve signals, which are processed in the brain.

As light falls on the retina, it strikes light-sensitive cells called rods and cones. The rods can detect all visible light, but only the cones can distinguish colour. There are 3 types of cones: red-sensitive, blue-sensitive, and green-sensitive. Each responds more strongly to a particular part of the light spectrum. Because the cones are most concentrated in a central area of the retina called the fovea, colour vision is most accurate for objects viewed directly and is poor at the edges of vision. When light hits a cone, it causes the cone to emit an electrical signal, which passes to the brain via the optic nerve. Colour perception requires a minimum level of light, below which everything is seen as shades of grey. (See also colour vision deficiency; eye; perception; vision.)... colour vision

Protection against pertussis and tetanus gradually wanes. In adults, pertussis is mild but can be transmitted to children. Since tetanus is serious at any age, boosters are recommended at the time of any dirty, penetrating injury if there has not been a vaccination in the past 10 years.

Reactions to the diphtheria and tetanus parts of the vaccine are rare.

The pertussis vaccine often causes slight fever and irritability for a day or so.

More serious reactions are extremely rare and include seizures and an allergic reaction, which may lead to sudden breathing difficulty and shock.

Permanent damage from the vaccine is even rarer.

Doctors are now agreed that for most children, the benefits of outweigh the minimal risk from the vaccine.

The pertussis element of the vaccine should not be given to children who have reacted severely to a preceding dose of the vaccine, or who have a progressing brain abnormality.... dpt vaccination

Any of the 4 heart valves may be affected by stenosis (narrowing), which causes the heart to work harder to force blood through the valve, or by incompetence or insufficiency (leakiness), which makes the valve unable to prevent backwash of blood. These defects cause characteristic heart murmurs.

Heart-valve defects may be present at birth (see heart disease, congenital), or they may be acquired later in life. The most common congenital valve defects are aortic stenosis and pulmonary stenosis. Acquired heart-valve disease is usually the result of degenerative changes or ischaemia affecting part of the heart and leading to aortic stenosis or mitral incompetence. Rheumatic fever can cause mitral stenosis, mitral incompetence, aortic valve defects, tricuspid stenosis and tricuspid incompetence. The heart valves may also be damaged by bacterial endocarditis.

Heart-valve disorders commonly lead to heart failure, arrhythmias, or symptoms resulting from reduced blood supply to body tissues.

Heart-valve defects may be diagnosed by auscultation, chest X-ray, ECG, or echocardiography and may be corrected by heart-valve surgery.... heart valve

A diagnosis is made by doppler ultrasound scanning.

Treatment depends on the site and extent of the clots.
