| syndrome, horner | A complex of abnormal findings, namely sinking in of one eyeball, ipsilateral ptosis (drooping of the upper eyelid on the same side) and miosis (constriction of the pupil of that eye) together with anhidosis (lack of sweating) and flushing of the affected side of the face. Due to paralysis of certain nerves (specifically, the cervical sympathetic nerves). Also called horner-bernard syndrome, bernard syndrome, bernard-horner syndrome and horner's ptosis but far and away best known as horner syndrome. (12 Dec 1998) |

| syndrome, hurler | A genetic error of metabolism. There is incomplete breakdown and accumulation of a substance (a mucopolysaccharide) which is abnormally stored in the brain and other places. This usually leads to death of the individual with hurler syndrome by their early teen years. See gargoylism. (12 Dec 1998) |
| syndrome, incontinentia pigmenti | A genetic disease with blisters that develop soon after birth on the trunk and limbs, then heal, but leave dark (hyperpigmented) streaks and marble-like whorls on the skin. (the name came from the erroneous idea that the skin cells were incontinent of pigment and could not contain it normally.) other key features of ip include dental and nail abnormalities, bald patches, and (in about 1/3rd of cases) mental retardation. Ip is an x-linked dominant with male lethality. The ip gene is in band q28 on the x chromosome. Mothers with ip have an equal chance of having a normal or ip daughter or a normal son. The ip sons die before birth. Ip is also known as bloch-sulzberger syndrome. (12 Dec 1998) |
| syndrome, irritable bowel | A common gastrointestinal disorder (also called spastic colitis, mucus colitis or nervous colon syndrome), ibs is an abnormal condition of gut contractions (motility) characterised by abdominal pain, bloating, mucous in stools, and irregular bowel habits with more than alternating diarrhoea and constipation, symtoms that tend to be chronic and wax and wane over the years. Although ibs can cause chronic recurrent discomfort, it does not lead to any serious organ problems. Diagnosis usually involves more than excluding other illnesses. Treatment is directed toward relief of symptoms and includes high fibre diet, exercise, relaxation techniques, avoidance of caffeine, milk products and sweeteners, and medications. (12 Dec 1998) |
| syndrome, joint hypermobility | See Syndrome, hypermobility. (12 Dec 1998) |
| syndrome, kartagener's | The trio of sinusitis, bronchitis and situs inversus (lateral reversal of the position all organs in the chest and abdomen with the heart and stomach on the right, the liver on the left, etc. Opposite or inverted from their usual position). (12 Dec 1998) |
| syndrome, kinky hair | Genetic disorder with fragile twisted ( kinky ) hair and progressive deterioration of the brain. Due to an error in copper transport resulting in copper deficiency. Females are carriers and their sons with the gene have the disease. Also known as menkes syndrome. (12 Dec 1998) |
| syndrome, klinefelter | The most common single cause of hypogonadism (underfunction of the gonads) and infertility in men, klinefelter syndrome is due to a chromosome abnormality with xxy (plus additional x or y chromosomes). It affects about 1 in 500 males and results in small testes (hypogenitalism), underproduction of testosterone and infertility (hypogonadism), and a long-limbed, long-trunked, relatively tall, slim build. Klinefelter boys tend to have learning and/or behavioural problems. at adolescence there is little growth of facial hair and a third of boys develop gynaecomastia (enlargement of the male breast). Named for the physician harry klinefelter who with e.c. Reifenstein, jr. And fuller albright (the founder of modern endocrinology) described the condition in 1942 long before its chromosomal basis became known. (12 Dec 1998) |
| syndrome, klippel-feil | The combination of short neck, low hairline at the nape of the neck and limited movement of the head. It is due to a defect in the early development of the spinal column in the neck (the cervival vertebrae). The condition is also called the klippel-feil sequence (referring to an embryologic or early developmental sequence of events). (12 Dec 1998) |
| syndrome, klippel-trenaunay-weber | A congenital malformation syndrome characterised by the triad of asymmetric limb hypertrophy, haemangiomata, and nevi. Asymmetric limb hypertrophy is enlargement of one limb and not the corresponding limb on the other side, the enlarged limb being 3 times more likely to be a leg than an arm in ktw; and the limb enlargement is of bone as well as soft tissue. The haemangiomas, abnormal nests of blood vessels that proliferate inappropriately and excessively, cover a remarkable range from small innocuous capillary haemangiomas ( strawberry marks ) to huge cavernous haemangiomas. The nevi are pigmented moles on the skin; in ktw there are often also dark linear streaks on the skin, streaks due to too much pigment. There can be other abnormalities but the triad is the consistent clinical centrepiece of the disease. most persons with ktw have an enlarged leg and do relatively well without treatment or, for example, with only compression from an elastic stocking. Skin ulcers and other skin problems can occur over the swollen leg. Usually, the treatment is conservative. Surgery is almost never needed. The only possible exceptions are the very rare situations in which the leg reaches gigantic proportions or secondary clotting difficulties arise (due to trapping and destruction of blood platelets in a huge haemangioma). Then, amputation may become necessary. The cause of ktw syndrome is unknown. (12 Dec 1998) |
| syndrome, lennnox | See Syndrome, Lennox-Gastaut. (12 Dec 1998) |
| syndrome, lennox-gastaut | A severe form of epilepsy that usually begins in early childhood and is characterised by frequent seizures of multiple types, mental impairment, and a particular brain wave pattern (a slow spike-and-wave pattern). The seizures that are notoriously hard to treat and may lead to falls and injuries can be reduced in frequency by treatment with lamotrigone, a chemically novel antiepileptic drug. The syndrome is named for w.g. Lennox and h. Gastaut who described it. (12 Dec 1998) |
| syndrome, li-fraumeni | A family tendency to cancers due to a mutation in a gene that normally serves to curb cancer: the p53 tumour-suppressor gene. Named after drs. Fred li and joe fraumeni. (12 Dec 1998) |
| syndrome, marfan | Inherited disorder with long fingers and toes, dislocation of the lens, and aortic wall weakness and aneurysm. (it has been suggested that abraham lincoln had marfan syndrome.) (12 Dec 1998) |
| syndrome, martin-bell | Better known as the fragile X syndrome, the most common heritable form of mental retardation. Fragile x syndrome is due to mutation (changes) at the fragile x site and so perforce is x-linked (carried on the x chromosome). Although it is usually more severe in males than females, the syndrome is due to a dynamic mutation (a trinucleotide repeat) that can change in length and hence in severity from generation to generation, from person to person, and even within a given person. The fragile x syndrome is known as the martin-bell syndrome in honor of their discovery of it in 1943. (12 Dec 1998) |
