Long Qt Syndrome: From 1 Different Sources
prolongation of the *Q–T interval on the electrocardiogram. It indicates susceptibility to ventricular tachycardia (especially *torsades de pointes), ventricular fibrillation, and sudden death. It may be familial or caused by certain drugs (e.g. sotalol, amiodarone, certain antipsychotic drugs).
(CFS) is a recently designated semi-disease, often attributed to EBV (the Epstein-Barr virus) or CMV (Cytomegalovirus) infections, characterized by FUOs (Fevers of Unknown Origin) and resulting in the patient suffering FLS (Feels Like Shit). In most of us, the microorganisms involved in CFS usually provoke nothing more than a head cold; in some individuals, however, they induce a long, grinding, and debilitating disorder, characterized by exhaustion, depression, periodic fevers...a crazy-quilt of symptoms that frustrates both the sufferer and the sometimes skeptical physician. MCS (Multiple Chemical Sensitivities) are another syndrome that is often lumped with CFS, and they may often be two faces of the same condition. I am not using all these acronyms to mock the conditions, but as an irony. There is too much (Acronym Safety Syndrome) in medicine, reducing complex and frustrating conditions to insider’s techno-babble, somehow therein trivializing otherwise complex, painful and crazy-making problems. The widest use of acronyms (AIDS, HIV, CFS, MCS, MS etc.) seems to be for diseases hardest to treat, least responsive to procedural medicine, and most depressing to discuss with patients or survivors.... chronic fatigue syndrome
A sensation of weakness and sweating after a meal in patients who have undergone GASTRECTOMY. Rapid emptying of the stomach and the drawing of ?uid from the blood into the intestine has been blamed, but the exact cause is unclear.... dumping syndrome
A pattern of symptoms and signs, appearing one by one or simultaneously, that together characterise a particular disease or disorder.... syndrome
A disorder in which abnormal FAECES occur as a result of a redundant loop in the small INTESTINE. The loop obstructs the normal ?ow of the contents of the bowel, causing stagnation. The syndrome is characterised by light-yellow, smelly, fatty, bulky faeces. The patient suffers from tiredness, malaise and loss of weight. Previous abdominal surgery is sometimes the cause, but the condition can be inherited. Blockage of intestinal contents upsets the bowel’s normal bacterial balance and hinders the normal absorption of nutrients. Treatment is either with antibiotics or, if that fails, surgery.... blind loop syndrome
A condition in which kidney failure occurs in patients who have been the victims of severe crushing accidents (see also KIDNEYS). The fundamental injury is damage to muscle. The limb swells. The blood volume falls. Blood UREA rises; there is also a rise in the POTASSIUM content of the blood. Urgent treatment in an intensive therapy unit is required and renal dialysis may well be necessary. The patient may survive; or die with renal failure. Post-mortem examination shows degeneration of the tubules of the kidney, and the presence in them of pigment casts.... crush syndrome
A disease of the peripheral nerves causing weakness and numbness in the limbs. It customarily occurs up to three weeks after an infection – for example, CAMPYLOBACTER infection of the gastrointestinal tract provoking an allergic response in the nerves. It may begin with weakness of the legs and gradually spread up the body. In the worst cases the patient may become totally paralysed and require to be arti?cially ventilated. Despite this, recovery is the rule.... guillain-barré syndrome
A collection of varying symptoms, such as persistent tiredness, headaches, muscle pain and poor concentration, reported by members of the Coalition Armed Forces who served in the 1991 Gulf War. Whilst there is strong evidence for a health e?ect related to service, there is no evidence of a particular set of signs and symptoms (the de?nition of a ‘syndrome’) unique to those who served in the Gulf War. Symptoms have been blamed on multiple possible hazards, such as exposure to depleted uranium munitions, smoke from oil-well ?res and use of pesticides. However, the only clearly demonstrated association is with the particular pattern of vaccinations used to protect against biological weapons. Many con?icts in the past have generated their own ‘syndromes’, given names such as e?ort syndrome and shell-shock, suggesting a link to the psychological stress of being in the midst of warfare.... gulf war syndrome
(IBS) This is a common and generally benign condition of the colon, taking different forms but usually characterized by alternating constipation and diarrhea. There is often some pain accompanying the diarrhea phase. The bowel equivalent of spasmodic asthma, its main cause is stress, often accompanied by a history of GI infections. Adrenalin stress slows the colon and causes constipation, followed by a cholinergic rebound overstimulation of the colon. It is also called spastic colon, colon syndrome, mucous colitis, even chronic colitis. True colitis is a potentially or actually serious pathology.... irritable bowel syndrome
Nephrotic syndrome is one of PROTEINURIA, hypo-albuminaemia and gross OEDEMA. The primary cause is the leak of albumin (see ALBUMINS) through the GLOMERULUS. When this exceeds the liver’s ability to synthesise albumin, the plasma level falls and oedema results. The nephrotic syndrome is commonly the result of primary renal glomerular disease (see KIDNEYS, DISEASES OF – Glomerulonephritis). It may also be a result of metabolic diseases such as diabetic glomerular sclerosis and AMYLOIDOSIS. It may be the result of systemic autoimmune diseases such as SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) and POLYARTERITIS NODOSA. It may complicate malignant diseases such as MYELOMATOSIS and Hodgkin’s disease (see LYMPHOMA). It is sometimes caused by nephrotoxins such as gold or mercury and certain drugs, and it may be the result of certain infections such as MALARIA and CROHN’S DISEASE.... nephrotic syndrome
This has been de?ned as ‘any combination of emotional or physical features which occur cyclically in a woman before MENSTRUATION, and which regress or disappear during menstruation’. It is characterised by mood-changes, discomfort, swelling and tenderness in the breasts, swelling of the legs, a bloated feeling in the abdomen, headache, fatigue and constipation. The mood-changes range from irritability and mild depression to outbursts of violence. It may last for 3–14 days. How common it is is not known, as only the more severe cases are seen by doctors, but it has been estimated that one in ten of all menstruating women suffer from it severely enough to require treatment. The cause is not known, but it is probably due to some upset of the hormonal balance of the body. In view of the multiplicity of causes that have been put forward, it is not surprising that there is an equal multiplicity of treatments. Among these, one of the most widely used is PROGESTERONE. Others include pyridoxine, danazol, and gamma linolenic acid available in the form of oil of evening primrose. Whatever drug may be prescribed, counselling is equally essential and, in many cases, is all that is required.... premenstrual syndrome
See ERYTHEMA – Erythema infectiosum.... slapped cheek syndrome
First described in 1978, this disorder is characterised by high fever, diarrhoea, SHOCK and a rash. It is frequently associated with the use of tampons (see TAMPON), but has occasionally been reported in men. The syndrome may also be linked to the use of contraceptives such as the diaphragm, cap and sponge (see under CONTRACEPTION), and skin wounds or infections may also be a cause. The disease is due to a staphylococcal toxin (see STAPHYLOCOCCUS; TOXINS). Treatment consists of supportive measures to combat shock and eradication of the staphylococcus by ANTIBIOTICS. The design of tampons has been improved. Recurrence of the disorder has been reported and women who have had an episode should stop using tampons and vaginal contraceptives.... toxic shock syndrome
Mongolism. Trisomy 21. Not a disease but a defect in mental and physical development. In the normal human being there are 46 chromosomes; in Down’s there are 47 – one extra No 21 chromosome. The syndrome increases with the age of the mother after the age of 35. Over the age of 40 the chances of a mother having such a child are 1-2 per cent. Children with the defect have low levels of zinc.
Cases of Down’s have followed use of nonoxynol-9 (vaginal contraceptive device) such as the polyurethane sponge. The sponge. when left in situ for a long time, may cause Down’s to follow.
Certain physical characteristics are present. The most important feature is impaired mental development. Almost all are coeliacs.
Symptoms. Low IQ, short fingers, small flat head, flattened nose, low-set ears. May be subject to umbilical hernia, and heart disease. No treatment can cure, but certain herb teas rich in minerals (Alfalfa, Red Clover) together with Kelp (either in tablet or powder form) may help children, with possible improvements in IQ. Vitamin supplements – A, D, Thiamine, Riboflavin, B6, B12, C and E improve a child’s physical and mental health – as do also the minerals: Magnesium, Calcium, Zinc, Manganese, Copper, Iron and Iodine.
Children with Down’s syndrome run an increased risk of coeliac disease, due to disturbed immunity. A substantial evidence is held in America that links a low level of Selenium in the mother. Unnecessary X- rays should be avoided. Ensure fitness before conception by gentle exercise and nutrients: Folic Acid, Selenium and Zinc.
Children with the condition are noted for their happy disposition and warmth of feeling towards others. ... down’s syndrome
A condition characterised by attacks of pain and tingling in the ?rst three or four ?ngers of one or both hands. The attacks usually occur at night. Carpal tunnel syndrome is caused by pressure on the median nerve as it passes under the strong ligament that lies across the front of the wrist. The condition may respond to use of a night splint on the hand; otherwise a corticosteroid injection under the ligament may help. If not, pressure is relieved by surgical division of the compressing ligament.... carpal tunnel syndrome
See MUSCLES, DISORDERS OF.... compression syndrome
A type of severe PRE-ECLAMPSIA (a disorder affecting some pregnant women) that affects various systems in the body. HAEMOLYSIS, raised concentration of the enzymes in the LIVER, and a low blood platelet count are among the characteristics (and explain the name HELLP); patients are acutely ill and immediate termination of pregnancy is necessary. (See also PREGNANCY AND LABOUR.)... hellp syndrome
This describes a condition in which a patient is awake and retains the power of sense perception, but is unable to communicate except by limited eye movements because the motor nervous system is paralysed. Several diseases can cause this syndrome, which results from interruption of some of the nerve tracts between the mid brain and the pons (see BRAIN). Sometimes the syndrome is caused by severe damage to muscles or the nerves enervating them. Locked-in syndrome may sometimes be confused with a PERSISTENT VEGETATIVE STATE (PVS).... locked-in syndrome
This term includes a multiplicity of diseases, all of which are characterised by faulty absorption from the INTESTINE of essential foodstu?s such as fat, vitamins and mineral salts. Among the conditions in this syndrome are COELIAC DISEASE, SPRUE, CYSTIC FIBROSIS and pancreatitis (see PANCREAS, DISORDERS OF). Surgical removal of the small intestine also causes the syndrome. Symptoms include ANAEMIA, diarrhoea, OEDEMA, vitamin de?ciencies, weight loss and, in severe cases, MALNUTRITION.... malabsorption syndrome

See MYALGIC ENCEPHALOMYELITIS (ME).... post-viral fatigue 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
Known colloquially as SADS, this is a disorder in which an affected individual’s mood changes with the seasons. He or she is commonly depressed in winter, picking up again in the spring. The diagnosis is controversial and its prevalence is not known. The mood-change is probably related to light, with MELATONIN playing a key role. (See also MENTAL ILLNESS.)... seasonal affective disorder syndrome
A term applied to a condition in which slowness of the PULSE is associated with attacks of unconsciousness, and which is due to ARRHYTHMIA of the cardiac muscle or even complete heart block. Usually the heart returns to normal rhythm after a short period, but patients who suffer from the condition are commonly provided with a PACEMAKER to maintain normal cardiac function (see also CARDIAC PACEMAKER).... stokes-adams syndrome
A rare disorder in which severe peptic ulcers recur in the stomach and duodenum (see DUODENAL ULCER; STOMACH, DISEASES OF). It is caused by a tumour in the PANCREAS that produces a hormone, GASTRIN, which stimulates the stomach and duodenum to produce excess acid: this causes ulceration. Treatment is by surgery.... zollinger-ellison syndrome
A rare, multisystem disorder with recurrent mouth ulcers and genital ulcers and inflammation of the eyes, skin joints, blood vessels, brain, and intestines. The cause of Behçet’s syndrome is unknown, but it is strongly associated with a genetically determined histocompatability antigen, -B51. Treatment is difficult and may require corticosteroid and immunosuppressant drugs. The condition often becomes long-term.... behçet’s syndrome
A painful cramp due to compression of a group of muscles within a confined space. It may occur when muscles are enlarged due to intensive training or injury such as shin splints. Cramps induced by exercise usually disappear when exercise is stopped. Severe cases may require fasciotomy to improve blood flow and prevent development of a permanent contracture.... compartment syndrome
A disorder caused by the secretion of excessive amounts of the hormone aldosterone by a noncancerous tumour of one of the adrenal glands. (See also aldosteronism.)... conn’s syndrome
A rare, congenital condition of severe mental handicap, abnormal facial appearance, low birth weight, and short stature, which is characterized by a cat-like cry in infancy. The syndrome is caused by a chromosomal abnormality. There is no treatment. (See also genetic counselling.)... cri du chat syndrome
A rare factitious disorder in which a person seeks, consciously or unconsciously, to mislead others about his or her mental state and may simulate symptoms of psychosis.... ganser’s syndrome
A rare autoimmune disorder causing inflammation of the glomeruli in the kidney (see glomerulus) and the alveoli in the lungs, and anaemia. It is a serious disease; unless treated early it may lead to lifethreatening bleeding into the lungs and progressive kidney failure. The disease is most common in young men, but can develop at any age and in women. Sometimes, it responds to treatment with immunosuppressant drugs and plasmapheresis. People who have severe or repeated attacks require dialysis and, eventually, a kidney transplant.... goodpasture’s syndrome
A group of physical signs (narrowing of the eye pupil, drooping of the eyelid, and absence of sweating) affecting 1 side of the face that indicates damage to part of the sympathetic nervous system (see autonomic nervous system).... horner’s syndrome
A chromosomal abnormality in which a male has 1, or occasionally more, extra X chromosomes in his cells, giving a complement of instead of. The risk of a baby having the condition increases with maternal age. Features of the syndrome vary in severity and may not become apparent until puberty, when gynaecomastia (breast enlargement) occurs and the testes remain small. Affected males are usually infertile (see infertility). They tend to be tall and thin with a female body shape and absence of body hair. Incidence of learning difficulties is higher in people with Klinefelter’s syndrome than in the general population. There is no cure for the disorder, but hormonal treatment can induce secondary sexual characteristics, and mastectomy may be used to treat gynaecomastia.... klinefelter’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
A rare condition in which there is an abnormal overgrowth of lymphocytes in the skin, liver, spleen, and lymph nodes. It mainly affects middleaged and elderly people. The first symptom is the appearance of red, scaly patches on the skin that spread to form an itchy, flaking rash. There may also be accumulation of fluid under the skin, baldness, and distorted nail growth. Sézary syndrome is sometimes associated with leukaemia. Treatment includes anticancer drugs and radiotherapy.... sézary syndrome
See ovary, polycystic.... stein-leventhal syndrome
Pain and other symptoms affecting the head, jaw, and face, thought to result when the temporomandibular joints and the muscles and ligaments attached to them do not work together correctly. Causes include spasm of the chewing muscles, an incorrect bite (see malocclusion), jaw, head, or neck injuries, or osteoarthritis. Common symptoms include headaches, tenderness of the jaw muscles, and aching facial pain. Treatment involves correction of any underlying abnormality, analgesic drugs, and, in some cases, injection of corticosteroid drugs into the joint.... temporomandibular joint syndrome
Chest pain localized to an area on the front of the chest wall, usually made worse by movement of the arms or trunk or by pressure on the chest wall. The syndrome is caused by inflammation of 1 or several rib cartilages and symptoms may persist for months. Treatment is with analgesics, nonsteroidal anti-inflammatory drugs, or local injections of corticosteroid drugs into the cartilage.... tietze’s syndrome

See under MUSCLES, DISORDERS OF – Compression syndrome.... anterior tibial syndrome
A lifelong personality disorder, evident from childhood and regarded as a mild form of AUTISM. Persons with the syndrome tend to have great di?culty with personal relationships. They tend to take what is said to them as literal fact and have great di?culty in understanding irony, metaphors or even jokes. They appear shy with a distant and aloof character, emotional rigidity and inability to adapt to new situations. They are often mocked and ill-treated at school by their fellows because they appear unusual. Many people with Asperger’s seem to take refuge in intense interests or hobbies, often conducted to an obsessional degree. Many become skilled in mathematics and particularly information technology. Frustration with the outside world which is so hard to comprehend may provoke aggressive outbursts when stressed.... asperger’s syndrome
This is a syndrome characterised by oral and genital ulceration, UVEITIS and ARTHROPATHY. THROMBOPHLEBITIS is a common complication, and involvement of the central nervous system may occur.... behçet’s syndrome
A lifelong disorder characterised by overactive behaviour, short attention span and poor concentration. It is thought to be caused by a minor abnormality that affects the part of the brain that allows us to concentrate and focus on tasks. Some scientists have suggested that it may be caused by particular foods, particularly processed foods containing arti?cial additives, and recommend special diets. In some countries, attention de?cit disorder is diagnosed in up to a tenth of all children; this may re?ect di?erences in paediatric practice and diagnosis rather than a real variation in prevalence of the disorder. Behaviour therapy is the main treatment. Those children with very severe symptoms of restlessness, short attention span and disturbed behaviour may respond to additional treatment with methylphenidate (Ritalin®). This is an amphetamine-like drug that is thought to stimulate the part of the brain that is not working properly. Use of this drug has, however, been controversial.... attention deficit disorder (hyperactivity syndrome)
See also MYALGIC ENCEPHALOMYELITIS (ME). A condition characterised by severe, disabling mental and physical fatigue brought on by mental or physical activity and associated with a range of symptoms including muscle pain, headaches, poor sleep, disturbed moods and impaired concentration. The prevalence of the condition is between 0.2 and 2.6 per cent of the population (depending on how investigators de?ne CFS/ME). Despite the stereotype of ‘yuppie ?u’, epidemiological research has shown that the condition occurs in all socioeconomic and ethnic groups. It is commoner in women and can also occur in children.
In the 19th century CFS was called neurasthenia. In the UK, myalgic encephalomyelitis (ME) is often used, a term originally introduced to describe a speci?c outbreak such as the one at the Royal Free Hospital, London in 1955. The term is inaccurate as there is no evidence of in?ammation of the brain and spinal cord (the meaning of encephalomyelitis). Doctors prefer the term CFS, but many patients see this as derogatory, perceiving it to imply that they are merely ‘tired all the time’ rather than having a disabling illness.
The cause (or causes) are unknown, so the condition is classi?ed alongside other ‘medically unexplained syndromes’ such as IRRITABLE BOWEL SYNDROME (IBS) and multiple chemical sensitivity – all of which overlap with CFS. In many patients the illness seems to start immediately after a documented infection, such as that caused by EPSTEIN BARR VIRUS, or after viral MENINGITIS, Q FEVER and TOXOPLASMOSIS. These infections seem to be a trigger rather than a cause: mild immune activation is found in patients, but it is not known if this is cause or e?ect. The body’s endocrine system is disturbed, particularly the hypothalamopituitary-adrenal axis, and levels of cortisol are often a little lower than normal – the opposite of what is found in severe depression. Psychiatric disorder, usually depression and/or anxiety, is associated with CFS, with rates too high to be explained solely as a reaction to the disability experienced.
Because we do not know the cause, the underlying problem cannot be dealt with e?ectively and treatments are directed at the factors leading to symptoms persisting. For example, a slow increase in physical activity can help many, as can COGNITIVE BEHAVIOUR THERAPY. Too much rest can be harmful, as muscles are rapidly weakened, but aggressive attempts at coercing patients into exercising can be counter-productive as their symptoms may worsen. Outcome is in?uenced by the presence of any pre-existing psychiatric disorder and the sufferer’s beliefs about its causes and treatment. Research continues.... chronic fatigue syndrome (cfs)
See EFFORT SYNDROME.... da costa’s syndrome
Also known as Da Costa’s syndrome, this is a condition in which symptoms occur, such as palpitations and shortness of breath, which are attributed by the patient to disorder of the heart. There is no evidence, however, of heart disease, and psychological factors are thought to be of importance. (See PSYCHOSOMATIC DISEASES.)... effort syndrome
A condition in which the subject suffers from a defect in one of the dividing walls (septum) of the HEART and this is accompanied by PULMONARY HYPERTENSION. The defect allows blood low in oxygen to ?ow from the right to the left side of the heart and be pumped into the aorta, which normally carries oxygenated blood to the body. The patient has a dusky blue appearance, becomes breathless and has a severely restricted exercise tolerance. There is an increase in red blood cells as the body attempts to compensate for the lowered oxygen delivery. The condition may be avoided by early surgical repair of the septal defect, but once it is evident, surgery may not be possible.... eisenmenger syndrome
See REPRESSED MEMORY THERAPY.... false-memory syndrome
A disorder of newborn infants that is caused by the toxic effects on the growing FETUS of excessive amounts of alcohol taken by the mother. Low birth-weight and retarded growth are the main consequences, but affected babies may have hand and facial deformities and are sometimes mentally retarded.... fetal alcohol syndrome
Symptoms These vary, with pain and fatigue generally prominent, sometimes causing considerable disability. Patients can usually dress and wash independently but cannot cope with a job or household activities. Pain is mainly axial, but may affect any region. ANALGESICS, NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS) and local physical treatments are generally ine?ective.
Patients often have a poor sleep pattern, waking exhausted. Unexplained headache, urinary frequency and abdominal symptoms are common, but no cause has been found. Patients generally score highly on measures of anxiety and DEPRESSION. Fibromyalgia is not an ideal description; idiopathic di?use-pain syndrome and non-restorative sleep disorder are increasingly preferred terms.
Clinical ?ndings are generally unremarkable; most important is the presence of multiple hyperalgesic tender sites (e.g. low cervical spine, low lumbar spine, suboccipital muscle, mid upper trapezius, tennis-elbow sites, upper outer quadrants of buttocks, medial fat pad of knees). In ?bromyalgia, hyperalgesia (excessive discomfort) is widespread and symmetrical, but absent at sites normally non-tender. Claims by patients to be tender all over are more likely to be due to fabrication or psychiatric disturbance. OSTEOARTHRITIS and periarticular syndrome are much more common and should be excluded, together with other conditions, such as hypothyroidism (see THYROID GLAND, DISEASES OF), SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) and in?ammatory myopathy (see MUSCLES, DISORDERS OF), which may present with similar symptoms.
Cause There is no investigational evidence of in?ammatory, metabolic or structural abnormality, and the problem seems functional rather than pathological. SEROTONIN de?ciency has a signi?cant role in ?bromyalgia syndrome.
Management Controlled trials have con?rmed the usefulness of low-dose AMITRIPTYLINE or DOTHIEPIN together with a graded exercise programme to increase aerobic ?tness. How this works is still unclear; its e?cacy may be due to its normalising effects on the sleep centre or ‘pain gating’ (reduction of pain sensation) at the spinal-cord level. Prognosis is often poor. Nevertheless, suitable advice and training can help most patients to learn to cope better with their condition and avoid unnecessary investigations and drug treatments.... fibromyalgia syndrome
A condition in children characterised by obesity, physical sluggishness, and retarded sexual development. It is the result of disturbed PITUITARY GLAND function.... fröhlich’s syndrome
Also known as Tourette’s syndrome, this is a hereditary condition of severe and multiple tics (see TIC) of motor or vocal origin. It usually starts in childhood and becomes chronic (with remissions). With a prevalance of one in 2,000, a dominant gene (see GENES) with variable expression may be responsible. The disorder is associated with explosive vocal tics and grunts, occasionally obscene (see COPROLALIA). The patient may also involuntarily repeat the words or imitate the actions of others (see PALILALIA). HALOPERIDOL, pimozide (an oral antipsychotic drug similar to CHLORPROMAZINE hydrochloride) and clonidine are among drugs that may help to control this distressing, but fortunately rare, disorder.... gilles de la tourette’s syndrome

An inherited disorder affecting about one person in 50,000 in which the CONNECTIVE TISSUE is abnormal. The result is defects of the heart valves, the arteries arising from the heart, the skeleton and the eyes. The victims are unusually tall and thin with a particular facial appearance (the US President Abraham Lincoln was said to have Marfan’s) and deformities of the chest and spine. They have spider-like ?ngers and toes and their joints and ligaments are weak. Orthopaedic intervention may help, as will drugs to control the heart problems. As affected individuals have a 50 per cent chance of passing on the disease to their children, they should receive genetic counselling.... marfan’s syndrome
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.

Piper longumPiperaceae: San: Pippali;Hin, Ben, Pun: Piplamul; Kan, Mal:Thippali ;Tam: Thippili; Mar: Pimpli;Tel: Pipppaloo; Ass: Piplu.Introduction: Long pepper is a slender aromatic climber whose spike is widely used in ayurvedic and unani systems of medicine particularly for diseases of respiratory tract. Pipalarishta, Pippalyasava, Panchakola, Pippalayadilauha, and Lavana bhaskar churan are common ayurvedic preparations made out of the dry spikes of female types. Ittrifal fauladi, Angaruya-i-kabir and Majun khadar are well known unani preparations of long pepper. Its roots also have several medicinal uses. The root is useful in bronchitis, stomach ache, diseases of spleen and tumours. Fruit is useful in vata and kapha, asthma, bronchitis, abdominal complaints, fever, leucoderma, urinary discharges, tumours, piles, insomnia and tuberculosis. Root and fruit are used in gout and lumbago. The infusion of root is prescribed after parturition to induce the expulsion of placenta. The root and fruit decoction are used in acute and chronic bronchitis and cough. It contains the alkaloid piperine which has diverse pharmacological activities, including nerve depressant and antagonistic effect on electro- shock and chemo -shock seizures as well as muscular incoordination.Distribution: The plant is a native of Indo-Malaya region. It was very early introduced to Europe and was highly regarded as a flavour ingredient by the Romans. The Greek name “Peperi”, the Latin “Piper” and the English “Pepper” were derived from the Sanskrit name “Pippali”. It grows wild in the tropical rain forests of India, Nepal, Indonesia, Malaysia, Sri lanka, Rhio, Timor and the Philippines. In India, it is seen in Assam, West Bengal, Uttar Pradesh, Madhya Pradesh, Maharashtra, Kerala, Karnataka.and Tamil Nadu. It is also cultivated in Bengal, Chirapunchi area of Assam, Akola-Amravati region of Maharashtra, Anamalai hills of Tamil Nadu, Orissa, Uduppi and Mangalore regions of Karnataka. Bulk of Indian long pepper comes from its wild growth in Assam, Shillong and West Bengal, supplemented by imports from Sri Lanka and Indonesia (Viswanathan,1995)Botany: Piper longum Linn. is a member of Piperaceae family. The plant is a glabrous perennial under-shrub with erect or sub-scandent nodose stem and slender branches, the latter are often creeping or trailing and rooting below or rarely scandent reaching a few metres height. Leaves are simple, alternate, stipulate, and petiolate or nearly sessile; lower ones broadly ovate, cordate; upper ones oblong, oval, all entire, smooth, thin with reticulate venation; veins raised beneath. It flowers nearly throughout the year. Inflorescence is spike with unisexual small achlamydeous densely packed flowers and form very close clusters of small greyish green or darker grey berries. Female spikes with short thick stalk varying from 1.5 to2.5 cm in length and 0.5 to 0.7 cm in thickness.A number of geographical races are available in different agroclimatic regions of India; the most popular being Assam, West Bengal and Nepal races. Piper officinarum DC; syn. Chavica officinarum Miquel, Piper pepuloides and Piper chaba Hunter are the other related species of importance.Agrotechnology: Long pepper is a tropical plant adapted to high rainfall areas with high humidity. An elevation of 100-1000 m is ideal. It needs partial shade to the tune of 20-30% for best growth. The natural habitat of the plant is on the borders of streams. It is successfully cultivated in well drained forest soils rich in organic matter. Laterite soils with high organic matter content and moisture holding capacity are also suitable for cultivation.Long pepper is propagated by suckers or rooted vine cuttings.15-20 cm long 3-5 nodded rooted vine cuttings establishes very well in polybags. The best time for raising nursery is March-April. Normal irrigation is given on alternate days. The rooted cuttings will be ready for transplanting in 2 months time. With the onset of monsoon in June the field is ploughed well and brought to good tilth. 15-20 cm raised beds of convenient length and breadth are taken. On these beds, pits are dug at 60 x 60 cm spacing and well decomposed organic manure at 100 g/pit is applied and mixed with the soil. Rooted vine cuttings from polybags are transplanted to these pits. Gap filling can be done after one month of planting.The crop needs heavy manuring at the rate of 20 t FYM/ha every year. Application of heavy dose organic matter and mulching increase water retention in the soil and control weeds. Small doses of chemical fertilisers can also be used. The crop needs irrigation once a week. Sprinkler irrigation is ideal. With irrigation the crop continues to produce spikes and off-season produce will be available. However, it is reported that unirrigated crop after the onset of monsoon grows vigorously and shows much hardiness than the irrigated crop.Crop losses can be heavy due to pests and diseases. Mealy bugs and root grubs, attack the plant particularly during summer. Infested plants show yellowing and stunted growth. Application of systemic insecticides like nuvacron or dimecron will control the pests. Adults and nymphs of Helopeltis theivora severely feeds on the foliage which can be controlled by 0.25% neem kernel suspension. Rotting of leaves and vines during monsoon season is caused by Colletotrichum glorosporiodes and necrotic lesions and blights on the leaves during summer is caused by Colletotrichum and Cercospora spp. These diseases can be controlled by spraying of 1% Bordeaux mixture repeatedly. A virus like disease characterised by yellowing and crinkling of leaves, stunted growth and production of spikes of smaller size and inferior quality was also recently reported.The vines start flowering six months after planting and flowers are produced almost throughout the year. The spikes mature in 2 months time. The optimum stage of harvest is when the spikes are blackish green. The pungency is highest at this stage. Spikes are hand picked when they become mature and then dried. The yield of dry spike is 400 kg /ha during first year, increases to 1000kg during third year and thereafter it decreases. Therefore, after 3 years the whole plant is harvested. The stem is cut close to the ground and roots are dug up. Average yield is 500 kg dry roots/ha (Viswanathan,1995).Piper longum can also be cultivated as an intercrop in plantations of coconut, subabul and eucalyptus.Post harvest technology: The harvested spikes are dried in sun for 4-5 days until they are perfectly dry. The green to dry spike ratio is 10:1.5 by weight. The dried spikes have to be stored in moisture proof containers. Stem and roots are cleaned, cut into pieces of 2.5-5 cm length, dried in shade and marketed as piplamool. There are three grades of piplamool, based on the thickness. The commercial drug consists 0.5-2.5 cm long ,0.5-2.5 mm thick, cylindrical pieces dirty light brown in colour and peculiar odour with a pungent bitter taste, producing numbness to the tongue.Properties and activity: The spike of long pepper contains 4-5% piperine, piplartin, piperolactam, N-isobutyl deca trans-2-trans-4-dienamide and piporadione alkaloides, besides 0.7 % essential oil. Roots gave the alkaloids piperine, piperlongumine (piplartine) and piperlonguminine; sesamine, methyl 3, 4, 5-trimethoxy cinnamate. Stem gave triacoutane 22, 23 - dihydrostigmasterol. Fruit essential oil contains piperidine, caryophyllene and sesquiterpene alcohol (Atal et al, 1975).The root is plungent, hot, stomachic, laxative, anthelmintic and carminative. The fruit is sweetish, pungent, hot, stomachic, aphrodisiac, alterative, laxative, antidysenteric, emmenagogue, abortifacient, diuretic and tonic. The essential oil is antimicrobial and anthelmintic.N-isobutyl-deca-trans-2-trans-4-dienamide is antitubercular.Piperine is hypotensive, antipyretic, analeptic, and nerve stimulant (Warrier et al, 1995).... long pepper
The term applied by athletes to a condition characterised by pain over the inner border of the shin, which occurs in most runners and sometimes in joggers. The syndrome, also known as shin splints, is due to muscular swelling resulting in inadequate blood supply in the muscle: hence the pain. The disorder may be the result of compartment syndrome (build-up of pressure in the muscles), TENDINITIS, muscle or bone in?ammation, or damage to the muscle. It usually disappears within a few weeks, responding to rest and PHYSIOTHERAPY, with or without injections. In some cases, however, it becomes chronic and so severe that it occurs even at rest. If the cause is the compartment syndrome, relief is usually obtained by a simple operation to relieve the pressure in the affected muscles.... medial tibial 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
In infants, certain staphylococcal bacteria (see STAPHYLOCOCCUS) can cause an acute toxic illness in which the subject develops sheets of bright ERYTHEMA, accompanied by shedding of layers of outer epidermis. The result is similar to a hot-water scald. The condition responds promptly to appropriate antibiotic therapy. Drug reactions, especially from sulphonamides, may cause a similar syndrome in adults. In drug-induced forms, mucosae are also affected and the disease is often fatal.... scalded-skin syndrome
See SARS.... severe acute respiratory syndrome (sars)
A type of non-accidental head-injury to infants. A study published in 2000 (Lancet, 4 November) suggests that almost 25 out of 100,000 children under a year old sustain brain damage from shaken impact syndrome, even if they do not strike any hard surface. So, of around 685,000 babies in this age-group in Britain, as many as 170 a year may suffer injury from violent shaking. The median age for admission to hospital for the condition in Scotland was 2.2 months in the 18 months from July 1998. A Swedish report has concluded that children at risk from CHILD ABUSE can be identi?ed and the incidence reduced by legislation banning corporal punishment.

A group of symptoms of unknown cause. It mainly affects women, and occasionally men, with pain and discomfort in the lower abdomen, a frequent urge to urinate and, in women, pain in the area of the VULVA. Investigation rarely results in any abnormal ?ndings. Postmenopausal women (see MENOPAUSE), who are the most common sufferers, may have in?ammation of the vulva due to thinning of the tissues in that area. Treatment is supportive, with the patient being advised to drink a lot of ?uid and maintain a high standard of personal hygiene.... urethral syndrome
A rare inherited condition in which the affected person suffers from premature ageing from adolescence onwards. His or her growth may be retarded, the skin become thin, and arterial disease, DIABETES MELLITUS and leg ulcers (see ULCER) develop. Treatment is symptomatic.... werner’s syndrome
A disorder of CONNECTIVE TISSUE, with dryness of the mouth (xerostomia) and dryness of the eye (kerato conjunctivitis sicca) occurring in association with RHEUMATOID ARTHRITIS. It occurs in approximately 10 per cent of patients with the latter condition, but it can occur – and frequently does so – independently of rheumatoid disease. The lack of tears gives rise to symptoms of dryness and grittiness of the eyes; the dry mouth can occasionally be so severe as to cause a DYSPHAGIA. The disease is due to the autoimmune destruction of the SALIVARY GLANDS and the lacrimal glands (see EYE – Lacrimal apparatus). The disorder is usually associated with speci?c HLA antigen (see HLA SYSTEM). Treatment is unsatisfactory and is limited to oral and ocular hygiene as well as the provision of arti?cial tears in the form of cellulose eye drops.... sjogren’s syndrome
6.5 cm wide, 5 cm thick, and weighs around 140 grams.
Adult kidneys have a smooth exterior, enveloped by a tough ?brous coat that is bound to the kidney only by loose ?brous tissue and by a few blood vessels that pass between it and the kidney. The outer margin of the kidney is convex; the inner is concave with a deep depression, known as the hilum, where the vessels enter. The URETER, which conveys URINE to the URINARY BLADDER, is also joined at this point. The ureter is spread out into an expanded, funnel-like end, known as the pelvis, which further divides up into little funnels known as the calyces. A vertical section through a kidney (see diagram) shows two distinct layers: an outer one, about 4 mm thick, known as the cortex; and an inner one, the medulla, lying closer to the hilum. The medulla consists of around a dozen pyramids arranged side by side, with their base on the cortex and their apex projecting into the calyces of the ureter. The apex of each pyramid is studded with tiny holes, which are the openings of the microscopic uriniferous tubes.
In e?ect, each pyramid, taken together with the portion of cortex lying along its base, is an independent mini-kidney. About 20 small tubes are on the surface of each pyramid; these, if traced up into its substance, repeatedly subdivide so as to form bundles of convoluted tubules, known as medullary rays, passing up towards the cortex. One of these may be traced further back, ending, after a tortuous course, in a small rounded body: the Malpighian corpuscle or glomerulus (see diagram). Each glomerulus and its convoluted tubule is known as a nephron, which constitutes the functional unit of the kidney. Each kidney contains around a million nephrons.
After entering the kidney, the renal artery divides into branches, forming arches where the cortex and medulla join. Small vessels come o? these arches and run up through the cortex, giving o? small branches in each direction. These end in a tuft of capillaries, enclosed in Bowman’s capsule, which forms the end of the uriniferous tubules just described; capillaries with capsule constitute a glomerulus.
After circulating in the glomerulus, the blood leaves by a small vein, which again divides into capillaries on the walls of the uriniferous tubules. From these it is ?nally collected into the renal veins and then leaves the kidney. This double circulation (?rst through the glomerulus and then around the tubule) allows a large volume of ?uid to be removed from the blood in the glomerulus, the concentrated blood passing on to the uriniferous tubule for removal of parts of its solid contents. Other arteries come straight from the arches and supply the medulla direct; the blood from these passes through another set of capillaries and ?nally into the renal veins. This circulation is con?ned purely to the kidney, although small connections by both arteries and veins exist which pass through the capsule and, joining the lumbar vessels, communicate directly with the aorta.
Function The kidneys work to separate ?uid and certain solids from the blood. The glomeruli ?lter from the blood the non-protein portion of the plasma – around 150–200 litres in 24 hours, 99 per cent of which is reabsorbed on passing through the convoluted tubules.
Three main groups of substances are classi?ed according to their extent of uptake by the tubules:
(1) SUBSTANCES ACTIVELY REABSORBED These include amino acids, glucose, sodium, potassium, calcium, magnesium and chlorine (for more information, see under separate entries).
(2) SUBSTANCES DIFFUSING THROUGH THE TUBULAR EPITHELIUM when their concentration in the ?ltrate exceeds that in the PLASMA, such as UREA, URIC ACID and phosphates.
(3) SUBSTANCES NOT RETURNED TO THE BLOOD from the tubular ?uid, such as CREATINE, accumulate in kidney failure, resulting in general ‘poisoning’ known as URAEMIA.... structure each kidney is about 10 cm long,

Disorder of consciousness, intellect, or mental functioning that is of organic (physical), as opposed to psychiatric, origin. Causes include degenerative diseases, such as Alzheimer’s disease; infections; certain drugs; or the effects of injury, stroke, or tumour. Symptoms range from mild confusion to stupor or coma. They may also include disorientation, memory loss, hallucinations, and delusions (see delirium). In the chronic form, there is a progressive decline in intellect, memory, and behaviour (see dementia). Treatment is more likely to be successful with the acute form. In chronic cases, irreversible brain damage may already have occurred. (See also psychosis.)... brain syndrome, organic
A rare disease in which red blood cells are destroyed prematurely and the kidneys are damaged, causing acute kidney failure. Thrombocytopenia can also occur. Haemolytic–uraemic syndrome most commonly affects young children and may be triggered by a serious bacterial or viral infection. Symptoms include weakness, lethargy, and a reduction in the volume of urine. Seizures may occur. Blood and urine tests can determine the degree of kidney damage. Dialysis may be needed until the kidneys have recovered. Most patients recover normal renal function.... haemolytic–uraemic syndrome
Pain and numbness in the hand and arm due to prolonged use of vibrating tools. Symptoms often also include blue or white coloration of the fingers and a tingling sensation in affected areas. Hand–arm vibration syndrome tends to develop slowly over years and is the result of repeated damage to blood vessels and nerves. Exposure to cold tends to aggravate the condition. There is no specific treatment, but avoiding vibrating tools is essential to prevent the disease progressing. In some cases, calcium channel blockers may help relieve some symptoms.... hand–arm vibration syndrome

The cause of shoulder–hand syndrome is unknown, but it may occur as a complication of myocardial infarction, stroke, herpes zoster, or shoulder injury. Recovery usually occurs in about 2 years. This period may be shortened by physiotherapy and corticosteroid drugs. In rare cases, a cervical sympathectomy is performed.... shoulder–hand syndrome
A rare degenerative disorder of unknown cause that progressively damages the autonomic nervous system. It begins gradually at age 60–70 and is more common in men. Symptoms include dizziness and fainting due to postural hypotension, urinary incontinence, impotence, reduced ability to sweat, and parkinsonism. The condition eventually leads to disability, and sometimes premature death. There is no cure or means of slowing degeneration, but many symptoms are relieved by drugs.... shy–drager syndrome

(Holmes-Adie syndrome) an abnormality of the pupils of the eyes, often affecting only one eye. The affected pupil is dilated and reacts slowly to light; the response on convergence *accommodation of the eyes is also slow (see tonic pupil). Tendon reflexes may be absent. The condition is almost entirely restricted to women. [W. J. Adie; Sir G. M. Holmes (1876–1965), British neurologist]... adie’s syndrome
Unpleasant mental and physical symptoms experienced when a person stops using a drug on which he or she is dependent (see drug dependence). Withdrawal syndrome most commonly occurs in those with alcohol dependence or dependence on opioids, in smokers, and in people addicted to tranquillizers, amfetamines, cocaine, marijuana, and caffeine.
Alcohol withdrawal symptoms start 6–8 hours after cessation of intake and may last up to 7 days. They include trembling of the hands, nausea, vomiting, sweating, cramps, anxiety, and, sometimes, seizures. (See also confusion, delirium tremens, and hallucinations.)
Opioid withdrawal symptoms start after 8–12 hours and may last for 7–10 days. Symptoms include restlessness, sweating, runny eyes and nose, yawning, diarrhoea, vomiting, abdominal cramps, dilated pupils, loss of appetite, irritability, weakness, tremor, and depression.
Withdrawal symptoms from barbiturate drugs and meprobamate start after 12–24 hours, beginning with tremor, anxiety, restlessness, and weakness, sometimes followed by delirium, hallucinations, and, occasionally, seizures. A period of prolonged sleep occurs 3–8 days after onset. Withdrawal from benzodiazepine drugs may begin much more slowly and can be life-threatening.
Withdrawal symptoms from nicotine develop gradually over 24–48 hours and include irritability, concentration problems, frustration, headaches, and anxiety. Discontinuation of cocaine or amfetamines results in extreme tiredness, lethargy, and dizziness. Cocaine withdrawal may also lead to tremor, severe depression, and sweating.
Withdrawal symptoms from marijuana include tremor, nausea, vomiting, diarrhoea, sweating, irritability, and sleep problems. Caffeine withdrawal may lead to tiredness, headaches, and irritability.
Severe withdrawal syndromes require medical treatment.
Symptoms may be suppressed by giving the patient small quantities of the drug he or she had been taking.
More commonly, a substitute drug is given, such as methadone for opioid drugs or diazepam for alcohol.
The dose of the drug is then gradually reduced.... withdrawal syndrome
(acute respiratory distress syndrome, ARDS) a form of *acute respiratory failure that occurs after a precipitating event, such as trauma, aspiration, or inhalation of a toxic substance; it is particularly associated with septic shock.

[E. Apert (1868–1940), French physician]... apert syndrome
a condition in which *amenorrhoea and infertility follow a major haemorrhage in pregnancy. It may result from overvigorous curettage of the uterus in an attempt to control the bleeding. This removes the lining, the walls adhere, and the cavity is obliterated to a greater or lesser degree. Some 50% of such patients are subsequently infertile, and of those who become pregnant, only a minority achieve an uncomplicated delivery. Compare Sheehan’s syndrome. [J. G. Asherman (20th century), Czechoslovakian gynaecologist]... asherman syndrome

Boerhaave (1668–1738), Dutch physician]... boerhaave’s syndrome
the neurological condition resulting when the spinal cord has been damaged. In those parts of the body supplied by the damaged segment there is a flaccid weakness and loss of feeling in the skin. Below the lesion there is a spastic paralysis on the same side and a loss of pain and temperature sensation on the opposite side. The causes include trauma and multiple sclerosis. [C. E. Brown-Séquard (1818–94), French physiologist]... brown-séquard syndrome
a condition, usually congenital, in which the tendon sheath of the superior oblique muscle of the *eye does not relax, thus limiting the elevation of the eye, especially in adduction. [H. W. Brown (20th century), US ophthalmologist]... brown’s syndrome
a rare condition that follows occlusion of the hepatic veins by thrombosis or nonthrombotic processes. In the majority of cases the cause is unknown but hypercoagulable states, local or disseminated malignancy, and infection are possible causes. It is characterized by abdominal pain, abdominal distension due to ascites, and jaundice. Clinical examination may reveal hepatomegaly, and *hepatic encephalopathy. [G. Budd (1808–82), British physician; H. Chiari (1851–1916), German pathologist]... budd–chiari syndrome
a condition in which feeding via a PEG tube (see gastrostomy) is blocked. It occurs when the internal retention disc (bumper) of the tube, which holds it in place inside the stomach, is overgrown by hypertrophic gastric mucosa and becomes embedded in the stomach wall. This serious complication requires surgical removal of the tube. It can be prevented by correct tube care: advancing, retracting, and rotating of the tube.... buried bumper syndrome

Classically, ecchymoses spontaneously appear and are associated with a prodrome of warmth and pain at the sites. The condition, which is seen primarily in young to middle-aged women, is induced by trauma and associated with *personality disorders. Research into the syndrome is sparse but recent publications suggest that only a minority of patients experience a serious reduction in their quality of life, that the condition seems to be dermal rather than systematic in most patients, and that it seems to be associated with ongoing stress. [L. K. Diamond (1902–1999), US paediatrician; F. H. Gardner (1919–2013), US haematologist]... gardner–diamond syndrome

a group of symptoms that represent a partial disintegration of the patient’s recognition of his or her *body image. It consists of an inability to name the individual fingers, misidentification of the right and left sides of the body, and inability to write or make mathematical calculations (see acalculia; agraphia). It is caused by disease in the association area of the dominant (usually left) parietal lobe of the brain. [J. G. Gerstmann (1887–1969), Austrian neurologist]... gerstmann’s syndrome
an autosomal *dominant condition that is caused by a mutation in the *prion protein gene and resembles *Creutzfeldt-Jakob disease (CJD).

impairment of renal function, which can occur in acute or chronic liver disease. The condition is associated with intrarenal vasoconstriction and extrarenal vasodilation and hypotension, and the kidney disease is functional rather than structural in nature. There are two common clinical presentations. An acute form (type 1) is characterized by rapid spontaneous deterioration in renal function against a background of acute liver failure, acute alcoholic hepatitis, or acute decompensation of chronic cirrhotic liver disease. A chronic form (type 2) is characterized by insidious onset and slowly progressive deterioration in renal function. This is most often observed in patients with decompensated cirrhosis and portal hypertension. The prognosis of hepatorenal syndrome is extremely poor, and the best hope of survival is usually with liver transplantation.... hepatorenal syndrome
a group of rare inherited disorders characterized by recurrent attacks of fever and inflammation in the absence of infection. They include familial Mediterranean fever (see polyserositis), tumour necrosis factor receptor-associated periodic syndrome (TRAPS), and the cryopyrin-associated periodic syndrome (CAPS).

This leads to learning disability, enlargement of the liver and spleen, and prominent coarse facial features (gargoylism). The disease is *sex-linked, being restricted to males, although females can be *carriers. Medical name: mucopolysaccharidosis type II. [C. H. Hunter (1872–1955), US physician]... hunter’s syndrome
an inherited immunodeficiency syndrome characterized by normal or high IgM levels with absence of IgA, IgG, and IgE (see immunoglobulin). Patients are susceptible to bacterial and opportunistic infections. Some cases are due to a mutation in the gene encoding the CD40 ligand, which is synthesized by *helper T cells and is involved in activation of B cells to produce circulating antibodies.... hyper-igm syndrome
a collection of symptoms resulting from an increase in the viscosity of blood. These symptoms include epistaxis (nosebleed), blurred vision, dizziness, headaches, drowsiness, confusion, and breathlessness. Hyperviscosity of the blood occurs in conditions such as polycythaemia, plasma-cell myeloma, leukaemia, and Waldenström’s macroglobulinaemia.... hyperviscosity syndrome
a familial condition that is the most common form of isolated *gonadotrophin deficiency; it is combined with underdevelopment of the olfactory lobes, causing *anosmia. The syndrome is caused by a gene *deletion on the short arm of the X chromosome. Patients often present with delayed puberty.

a condition in males characterized by absence of penile erection combined with absence of pulses in the femoral arteries and wasting of the buttock muscles. It is caused by occlusion of the abdominal aorta and iliac arteries. [R. Leriche (1879–1956), French surgeon]... leriche’s syndrome
a rare autosomal *dominant condition characterized by hypertension associated with hypokalaemia, metabolic alkalosis, and low levels of plasma *renin and *aldosterone. The hypertension often starts in infancy and is due to excess resorption of sodium and excretion of potassium by the renal tubules. The syndrome is caused by a single genetic mutation on chromosome 16, which results in dysregulation of a sodium channel in the distal convoluted tubule. Treatment is with a low salt diet and a potassium-sparing diuretic that directly blocks the sodium channel, such as amiloride or triamterene. [G. G. Liddle (1921–89), US endocrinologist]... liddle’s syndrome
an acute form of *sarcoidosis characterized by fever, *erythema nodosum, enlarged lymph nodes near the inner border of the lungs, joint pain or inflammation, often involving the ankles, and *uveitis.

(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.

Clinical complications include heart failure, *paraesthesia, muscle weakness, cardiac *arrhythmias, fitting, and death. An assessment to identify at-risk patients before the reinstatement of feeding, regular monitoring, and prompt correction of electrolyte abnormalities helps to prevent this condition.... refeeding syndrome
(partial androgen insensitivity syndrome) a congenital resistance to androgen hormones (see androgen insensitivity syndrome) resulting in poor development of the male sexual characteristics, which often becomes more obvious at puberty. Some features of feminization may occur (e.g. breast development). [E. C. Reifenstein (1908–75), US endocrinologist]... reifenstein’s syndrome

(thoracic outlet syndrome) the group of symptoms caused by compression of the subclavian artery and the lower roots of the brachial plexus against the fibrous and bony structures of the outlet of the upper thoracic vertebrae. Loss of sensation, wasting, and vascular symptoms may be found in the affected arm, which may also be painful.... scalenus syndrome
the autoimmune destruction of a combination of the thyroid, the adrenals, and the beta cells of the islets of Langerhans, causing type 1 *diabetes mellitus. It is often associated with failure of the ovaries (causing an early menopause), the parathyroids, and the parietal cells of the *gastric glands (causing pernicious anaemia). [M. B. Schmidt (1863–1949), German physician]... schmidt’s syndrome
a rare disorder characterized by chronic *urticaria, fever, bone or joint pain, and enlarged lymph nodes in the neck. There are increased levels of an antibody, IgM (see immunoglobulin), produced by plasma cells. Treatment with *anakinra is very effective. [L. Schnitzler (20th century), French dermatologist]... schnitzler’s syndrome

a condition in which *amenorrhoea and infertility follow a major haemorrhage in pregnancy. It is caused by necrosis (death) of the anterior lobe of the pituitary gland as a direct result of the haemorrhage reducing the blood supply to the gland. Compare Asherman syndrome. [H. L. Sheehan (20th century), British pathologist]... sheehan’s syndrome
intestinal failure that occurs when the small bowel is shortened by surgery or trauma, resulting in reduced absorption of nutrients. Some bowel adaptation does occur, but if under 200 cm of small bowel remain it is likely patients will need long-term *total parenteral nutrition.... short bowel syndrome

(SAS) see obstructive sleep apnoea.... sleep apnoea syndrome
an uncommon anorectal condition that produces symptoms of anal pain, rectal bleeding, straining during defecation, and obstructed defecation (dyssynergic defecation). *Proctoscopy reveals one or more benign rectal lesions, which are thought to be due to abnormal straining during defecation leading to prolapse of the distal anterior rectal wall and internal anal *intussusception.... solitary rectal ulcer syndrome
(cerebral gigantism) a rare inherited disorder resulting in excessive physical growth during the first 2–3 years of life. It presents in childhood with a characteristic facial appearance, a disproportionately large head, large hands and feet, abnormally widely spaced eyes (ocular *hypertelorism), developmental delay, and tall stature for age. Children with Sotos syndrome tend to be large at birth and taller and heavier, stabilizing after about five years to achieve normal adult height. Most cases occur sporadically, although familial cases have been reported. [J. F. Sotos (1927– ), U.S. paediatrician]... sotos syndrome

(Ritter’s disease) a potentially serious condition of young infants (and occasionally seen in adults) in which the skin becomes reddened and tender and then peels off, giving the appearance of a scald. The area of skin loss may be quite extensive and is usually centred on the armpits and groin. The underlying cause is an infection by certain bacteria of the genus *Staphylococcus. It is contagious and may occur in clusters. Treatment is by antibiotics (usually intravenous), but careful nursing is essential to prevent skin damage. Admission to hospital is mandatory for small children.... staphylococcal scalded skin syndrome

(SCDS) a rare condition characterized by sound- or pressure-induced vertigo (see Tullio phenomenon), hearing loss, *autophony, and a sense of fullness in the affected ear. It is associated with absence of the bone that normally lies over the superior *semicircular canal. Diagnosis involves computerized tomography and *vestibular evoked myogenic potential testing. Treatment involves surgery to repair the bony defect.... superior canal dehiscence syndrome
see metabolic syndrome.... syndrome x
sudden extensive damage to the left *ventricle that classically occurs following acute emotional shock. The clinical syndrome mimics acute *myocardial infarction, but no coronary artery is occluded and the extent of ventricular damage exceeds that supplied by any single coronary artery. The appearance of the left ventriculogram resembles a Japanese lobster pot, from which the name derives. The cause is unknown, and in most cases spontaneous recovery occurs.... takotsubo syndrome
a condition resulting from damage to the thalamus, often by a stroke, that is characterized by severe intractable pain and hypersensitivity in the area of the body served by the damaged brain region. It is extremely resistant to treatment.... thalamic syndrome
(SIADH) a condition of inappropriately high plasma levels of ADH (see vasopressin) with associated water retention, dilutional *hyponatraemia, and the production of highly concentrated urine. Renal, adrenal, thyroid, and hepatic function are normal, as is the volume of circulating blood (euvolaemia). It is caused by a variety of pathological conditions, usually intrathoracic and intracerebral, and also by a number of drugs, including antidepressants, chemotherapy agents, and some of the older antidiabetic agents. The treatment involves fluid restriction, treatment (or removal) of the underlying cause (or drug), and, in severe cases, administration of *demeclocycline to reduce the effects of ADH on the kidney. Very rarely, hypertonic saline is given.... syndrome of inappropriate secretion of antidiuretic hormone
involuntary persistent contraction of the tensor tympani muscle in the middle ear, attached to the malleus bone, giving rise to tinnitus, distorted hearing, a sensation of blockage of the ear, or pain.... tonic tensor tympani syndrome
(Treacher Collins deformity) a hereditary disorder of facial development. It is characterized by underdevelopment of the jaw and zygomatic (cheek) bones and the precursors of the ear fail to develop, which results in a variety of ear and facial malformations. The ear abnormality may cause deafness. [E. Treacher Collins (1862–1919), British ophthalmologist]... treacher collins syndrome
(TTTS) a condition in which communicating vessels in the shared placenta of monochorionic twins (see chorionicity) divert blood to one fetus (the recipient) from the other (the donor), resulting in one fetus with increased blood volume and one anaemic fetus. It complicates 15% of monochorionic twin pregnancies, and a system of ultrasound staging has been developed to assess the severity of the syndrome. TTTS is associated with a high perinatal mortality rate. There is significant morbidity and poor neurodevelopmental outcome in surviving infants due to complications of the disease itself and the high preterm birth rate that invariably accompanies this condition. A range of treatments, including *amnioreduction, *septostomy, and laser ablation of the communicating vessels, have led to an improvement in overall perinatal survival rates.... twin-to-twin transfusion syndrome

an inherited form of deafness accompanied by a characteristic white forelock of hair and multiple colours within the irises of the eyes. It is inherited as an autosomal *dominant disease, i.e. the children of an affected parent have a 50% chance of inheriting the disorder, although severity is variable. The gene responsible has been identified. [P. J. Waardenburg (1886–1979), Dutch ophthalmologist]... waardenburg’s syndrome

acute haemorrhage in the adrenal glands with haemorrhage into the skin associated with the sudden onset of acute bacteraemic *shock. It is usually caused by meningococcal septicaemia (see meningitis). [R. Waterhouse (1873–1958), British physician; C. Friderichsen (20th century), Danish physician]... waterhouse–friderichsen syndrome
see MENS. [P. Wermer, US physician]... wermer’s syndrome
a rare genetic disorder resulting in premature ageing that starts at adolescence. Growth may be retarded and affected individuals may suffer from a thin skin, arterial disease, leg ulcers, and diabetes. Treatment is limited to the management of complications, such as diabetes. The gene responsible codes for an enzyme involved in the mechanisms of DNA replication and repair, which in affected individuals is defective. [C. W. O. Werner (1879–1936), German physician]... werner’s syndrome
a hereditary condition, caused by a defect (a *deletion) in chromosome 7, marked by a characteristic ‘elfin’ facial appearance (including large eyes, a wide mouth, and small chin), *hypercalcaemia, short stature, learning disabilities, and *aortic stenosis. Most affected children are highly sociable and have unusual conversational ability, using a rich and complex vocabulary. The condition can be diagnosed prenatally. [J. C. P. Williams (20th century), British physician]... williams syndrome
a rare *sex-linked recessive disorder characterized by eczema, *thrombocytopenia, and deficiency in the immune response (*immunodeficiency). It is caused by a decrease in the amount of Wiskott–Aldrich syndrome protein (WASP: a protein occurring in lymphocytes, platelets, and other cells) due to a mutation in the WASP gene.... wiskott–aldrich syndrome
(DIDMOAD syndrome) a rare syndrome consisting of a combination of *diabetes insipidus, *diabetes mellitus, *optic atrophy, and *deafness.... wolfram syndrome
a congenital abnormality of heart conduction caused by the presence of an *accessory pathway of conduction between the atria and ventricles. It results in premature excitation of one ventricle and is characterized by an abnormal wave (delta wave) at the start of the QRS complex on the electrocardiogram. The accessory pathway predisposes the patient to episodes of fast heart rate due to the rapid self-sustaining circulation of an electrical impulse from the atria to the ventricles and back again (*atrioventricular reciprocating tachycardia). Emergency treatment is in the form of drugs that temporarily block the re-entry circuit. Permanent destruction of the accessory pathway by *radiofrequency ablation is usually curative. [L. Wolff; Sir J. Parkinson (1885–1976), British physician; P. D. White (1886–1973), US cardiologist]... wolff–parkinson–white syndrome
(XLP syndrome, Duncan’s disease) a hereditary disorder of the immune system caused by a defective *sex-linked gene carried on an *X chromosome. There is uncontrolled proliferation of B-*lymphocytes in response to infection by the Epstein-Barr virus, which can lead to fulminating hepatitis or lymphoma. This condition is due to a defect in a gene, SAP, which encodes a signalling molecule found in the cytoplasm of cells.... x-linked lymphoproliferative syndrome
see X-linked lymphoproliferative syndrome.... xlp syndrome
a combination of severe *hyperlipidaemia, haemolytic *anaemia, and *jaundice seen in susceptible individuals drinking alcohol to excess. [L. Zieve (1915–2000), US physician]... zieve’s syndrome
