A short-lived cardiac sound having little duration (less than 0.12 second) as distinct from a murmur; e.g., first, second, third, and fourth heart sounds, clicks, and opening snaps. Origin: L.

| transient acantholytic dermatosis | A pruritic papular eruption, with histologic suprabasal acantholysis, of the chest, with scattered lesions of the back and lateral aspects of the extremities, lasting from a few weeks to several months; seen predominantly in males over 40. Synonym: Grover's disease. (05 Mar 2000) |
| transient agammaglobulinaemia | A type of primary immunodeficiency that occurs in infants of both sexes, usually before the sixth month of life, probably resulting from immaturity of lymphoid tissue. Synonym: transient agammaglobulinaemia. (05 Mar 2000) |
| transient albuminuria | Albuminuria of a temporary or short-lived nature. (05 Mar 2000) |
| transient global amnesia | A memory disorder seen in middle aged and elderly persons characterised by an episode of amnesia and bewilderment which persists for several hours; during the episode the patient has a memory defect for present and recent past events, but is fully alert, oriented, capable of high-level intellectual activity, and has a normal neurological examination. Typically, these amnesic episodes occur spontaneously, and most patients experience only one; of uncertain aetiology-probably ischemic, but not due to atherosclerosis. (05 Mar 2000) |
| transient hypogammaglobulinaemia of infancy | A type of primary immunodeficiency that occurs in infants of both sexes, usually before the sixth month of life, probably resulting from immaturity of lymphoid tissue. Synonym: transient agammaglobulinaemia. (05 Mar 2000) |
| transient ischaemic attack | A transient ischaemic attack is a temporary paralysis, numbness, speech difficulty or other neurologic symptoms that start suddenly and recovers within 24 hours (typically resolve over several hours). See: neurologic symptoms, stroke. Acronym: TIA (26 Mar 1998) |
| transient ischemic attack | A sudden focal loss of neurological function with complete recovery usually within 24 hours; caused by a brief period of inadequate perfusion in a portion of the territory of the carotid or vertebral basilar arteries. (05 Mar 2000) |
| transient retinopathy | Transient traumatic retinal angiopathy due to a sudden rise in venous pressure, as in compression of the body from seat belt injury; ocular fundi show large white patches associated with the retinal veins about the disk or macula, haemorrhages, and retinal oedema; thought to be due to fat embolism from bone marrow.

| transin | <enzyme> Protease secreted by carcinoma cells: carboxy terminal domain has distant homology to haemopexin (hem binding protein) and the N terminal domain has the proteolytic activity. May be involved in digestion of extracellular matrix. (18 Nov 1997) |
