| syndrome, reye's | A sudden, sometimes fatal, disease of the brain (encephalopathy) with degeneration of the liver, occurs in children (most cases 4-12 years of age), comes after the chickenpox (varicella) or an influenza-type illness, is also associated with taking medications containing aspirin. The child with reye's syndrome first tends to be unusually quiet, lethargic (stuporous), sleepy, and vomiting. In the second stage, the lethargy deepens, the child is confused, combative and delirious. And things get worse from there with decreasing consciousness, coma, seizures, and eventually death. The prognosis (outlook) depends on early diagnosis and control of the increased intracranial pressure. Reye's syndrome is a good reason to have your child immunised against chickenpox and not give a child aspirin for fever. (12 Dec 1998) |

| syndrome, shprintzen | Congenital malformation (birth defect) syndrome with cleft palate, heart defect, abnormal face, and learning problems.the condition is also called the velo-cardio-facial (vcf) syndrome. (the velum is the soft palate). Other less frequent features include short stature, small-than-normal head (microcephaly), mental retardation, minor ear anomalies, slender hands and digits, and inguinal hernia. The cause is usually a microdeletion in chromosome band 22q11.2, just as in digeorge syndrome. Shprintzen and digeorge syndromes are different clinical expressions of essentially the same chromosome defect. Syndrome, stein-leventhal: known descriptively as polycystic ovarian disease (pco), this syndrome is basically an hormonal problem that causes women to have a variety of symptoms including irregular or no periods, acne, obesity and excessive hair growth. Women with pco are at a higher risk for uterine cancer (endometrial cancer), diabetes, high blood pressure, and heart disease. With proper treatment, risks can be minimised. The syndrome is named after the late american gynecologists irving f. Stein, sr. And michael leo leventhal. (12 Dec 1998) |
| syndrome, shulman's | A disease which leads to inflammation and thickening of the skin and fascia. (the fascia is a lining tissue under the skin that covers a surface of underlying tissues.) when the fascia is inflamed, the condition is referred to as fasciitis. In eosinophilic fasciitis, the involved fascia is inflamed with the eosinophil white blood cells. There is progressive thickening, and often redness and warmth, and hardness of the skin surface.

| syndrome, tar | TAR stands for Thrombocytopenia (low blood platelets) and aplasia (absence) of the radius (the long bone on the thumb-side of the forearm), features characterizing this syndrome. There is phocomelia more than (flipper-limb) with the thumbs always present. The fibula (the smaller bone in thye lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the tar child. Alternative names include more than thrombocytopenia-absent radius syndrome, radial aplasia-thrombocytopenia syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
| syndrome, tempero-mandibular joint | Disorder of the temporo-mandibular joint(tmj) causing pain usually in front of the ear. Pain in the tmj can be due to trauma (such as a blow to the face), inflammatory or degenerative arthritis, or by the mandible being pushed back towards the ears whenever the patient chews or swallows. Sometimes, muscles around the tmj used for chewing can go into spasm, causing head and neck pain and difficulty opening the mouth normally. (12 Dec 1998) |

| syndrome, tmj | Disorder of the temporo-mandibular joint (tmj) causing pain usually in front of the ear. Pain in the tmj can be due to trauma (such as a blow to the face), inflammatory or degenerative arthritis, or by the mandible being pushed back towards the ears whenever the patient chews or swallows. Sometimes, muscles around the tmj used for chewing can go into spasm, causing head and neck pain and difficulty opening the mouth normally. (12 Dec 1998) |
| syndrome, toxic shock | A grave condition occurring predominantly in menstruating women using tampons, toxic shock is characterised by a highly toxic state (with sudden high fever, vomiting, diarrhoea, muscle aching) followed by low blood pressure (hypotension) which can lead to shock (and death). There may be a rash resembling sunburn with peeling of skin. The channing laboratory in boston under dr. Edw. Kass discovered that toxic shock was due to a toxin produced by staph (staphylococcus) aureus bacteria growing under conditions with little or no oxygen. The syndrome occurs rarely in women not using tampons and in men. (12 Dec 1998) |
| syndrome, trisomy 13 | Condition with three rather than the normal two chromosomes 13. Children born with this syndrome have multiple malformations and mental retardation due to the extra chromosome 13. The congenital malformations (birth defects) commonly include scalp defects, more than haemangiomas more than (blood vessel malformations) of the face and nape of the neck, cleft lip more than and palate, malformations of the heart and abdominal organs, and flexed fingers with extra digits. The mental retardation is profound. The iq is untestably low. The majority of trisomy 13 babies die soon after birth or in infancy. The condition is also called patau syndrome after the late geneticist klaus patau more than (at the university of wisconsin) who discovered the extra chromosome in 1960. (12 Dec 1998) |
| syndrome, trisomy 18 | There are three instead of the normal two chromosomes 18. Children with this condition have multiple malformations and mental retardation due to the extra chromosome 18. The children characteristically have low birth weight, small head (microcephaly), small jaw (micrognathia), malformations of the heart and kidneys, clenched fists with abnormal finger positioning, and malformed feet. The mental retardation is profound with the iq too low to edven test. Nineteen out of 20 (95%) of these children die before their first birthday. The condition is also called edwards syndrome in honor of the british physician and geneticist john edwards who discovered the extra chromosome in 1960. (12 Dec 1998) |
| syndrome, trisomy 21 | A common chromosome disorder due to an extra chromosome number 21 (trisomy 21). The syndrome causes mental retardation, a characteristic face, and multiple malformations. It is associated with a major risk for heart problems, a lesser risk of duodenal atresia (part of the intestines not developed), and a minor but still significant risk of acute leukaemia. Trisome 21 syndr0ome is also commonly called down syndrome after the 19th century english doctor langdon down who was curiously enough not the first person to describe the condition, added little to knowledge and, in great error, attributed the condition to a reversion to the mongoloid race. The disorder was also once called mongolism, a term now considered slang. (12 Dec 1998) |
