| dentatorubral cerebellar atrophy with polymyoclonus | A familial disorder beginning in late childhood, characterised by progressive cerebellar ataxia, action myoclonus and preserved intellect. Probably due to multiple causes, mitochondrial abnormalities being one. Synonym: dentatorubral cerebellar atrophy with polymyoclonus. (05 Mar 2000) |
|---|---|
| inferior cerebellar peduncle | Large paired bundles of nerve fibres which develop on the dorsolateral surfaces of the upper medulla, extend under the lateral recesses of the rhomboid fossa and curve dorsally into the cerebellum medial to the middle cerebellar peduncle; composed of a larger (lateral) bundle, the restiform body, and a small (medial) bundle, the juxtarestiform body. Fibres forming this composite bundle originate from spinal neurons and medullary relay nuclei. The largest constituent (restiform body) is crossed fibres from the inferior olive; it also contains the dorsal spinocerebellar tract and cerebellar projections from the lateral reticular nucleus, the accessory cuneate nucleus, the paramedian reticular nuclei and the perihypoglossal nuclei. Vestibulocerebellar fibres are placed medially in the inferior cerebellar peduncle and are usually separately identified as the juxtarestiform body. Synonym: pedunculus cerebellaris inferior.

| inferior surface of cerebellar hemisphere | It rests in the posterior cranial fossa and overlies the medulla; it includes the semilunaris inferior, biventer lobule, cerebellar tonsil, and flocculus. Synonym: facies inferior hemispherii cerebelli. (05 Mar 2000) |
| inferior veins of cerebellar hemisphere | Several veins draining the inferior portion of the cerebellar hemispheres; they terminate in the petrosal vein. Synonym: venae hemispherii cerebelli inferiores. (05 Mar 2000) |
| juvenile cerebellar astrocytoma | <oncology, tumour> This primary brain tumour of the cerebellum accounts for 10 to 30% of brain tumours in children. The are usually slow growing and benign. Symptoms include gait problems, clumsiness, headache and vomiting. Treatment often involves a combination of surgery, radiation therapy and chemotherapy. (27 Sep 1997) |
| layers of cerebellar cortex | The thin gray surface layer of the cerebellum, consisting of an outer molecular layer or stratum moleculare, a single layer of Purkinje cells (the ganglionic layer), and an inner granular layer or stratum granulosum. Synonym: cortex cerebelli. (05 Mar 2000) |
| abdomen, acute | Clinical syndrome characterised by abdominal pain of great severity associated with other symptoms and signs, usually those of acute peritonitis, which might well be the result of a ruptured abdominal viscus or a similar abdominal catastrophe requiring urgent surgical operation. (12 Dec 1998) |
| acute | 1. Sharp, poignant. 2. Having a short and relatively severe course. Origin: L. Acutus = sharp (18 Nov 1997) |
| acute abdomen | Any serious acute intra-abdominal condition (such as appendicitis) attended by pain, tenderness, and muscular rigidity, and for which emergency surgery must be considered. Synonym: surgical abdomen. (05 Mar 2000) |
| acute abscess | A recently formed abscess with little or no fibrosis in the wall of the cavity. Synonym: hot abscess. (05 Mar 2000) |
| acute adrenal crisis | <endocrinology> An abrupt life-threatening state which is caused by insufficient production of cortisol by the adrenal gland. A typical finding in Addison's disease. Individuals who have been taking corticosteroids (glucocorticoids) for a prolonged period of time (weeks to months) are at risk for acute adrenal crisis if the medication is stopped abruptly. For this reason, corticosteroid medication are withdrawn slowly on a diminishing dosing schedule. Symptoms include low blood pressure (shock), weakness, headache, vomiting, fever chills, tachycardia and sweating. Treatment includes blood pressure support and intravenous hydrocortisone. (27 Sep 1997) |
| acute adrenocortical insufficiency | Severe adrenocortical insufficiency when an intercurrent illness or trauma causes an increased demand for adrenocortical hormones in a patient with adrenal insufficiency due to disease or use of relatively large amounts of similar hormones as therapy; characterised by nausea, vomiting, hypotension, and frequently hyperthemia, hyponatraemia, hyperkalaemia, and hypoglycaemia; can be fatal if untreated. Synonym: addisonian crisis, adrenal crisis, Bernard-Sergent syndrome. (05 Mar 2000) |
| acute African sleeping sickness | A disease of humans caused by Trypanosoma brucei rhodesiense in eastern Africa from Ethiopia and Uganda south to Zimbabwe; it is clinically similar to Gambian trypanosomiasis but of shorter duration and more acute in form; patients suffer repeated episodes of pyrexia, become anaemic, and die commonly from cardiac failure. Synonym: acute African sleeping sickness, acute trypanosomiasis, East African sleeping sickness, East African trypanosomiasis. (05 Mar 2000) |
| acute alcoholism | A temporary deterioration in mental function, accompanied by muscular incoordination and paresis, induced by the rapid ingestion of alcoholic beverages. Synonym: intoxication. (05 Mar 2000) |
| acute angle | Any angle less than 90 |
