| EFP | early follicular phase; effective filtration pressure; endoneural fluid pressure |
|---|---|
| FFAP | free fatty acid phase |
| G0 | quiescent phase of cells leaving the mitotic cycle |
| G1 | presynthetic gap [phase of cells prior to DNA synthesis] |
| G2 | postsynthetic gap [phase of cells following DNA synthesis] |
| acute urethral syndrome | <syndrome> This describes a clinical syndrome of dysuria (pain on urination) with sterile or low bacterial colony count culture results. Many of these patients have early or low-grade E. Coli, Staphylococcal saprophyticus or Chlamydia trachomatis infections. All are treated with antibiotics. (27 Sep 1997) |
|---|---|
| acute urticaria | Urticaria accompanied by slight constitutional symptoms. Synonym: acute urticaria, urticaria acuta, urticaria febrilis. (05 Mar 2000) |
| acute vascular occlusion | <cardiology, surgery> A serious condition that results from the sudden blockage of an artery, usually with a blood clot. (27 Sep 1997) |
| acute vascular purpura | <dermatology> This relatively rare disorder is characterised by skin purpura, joint pains, abdominal pain and renal disease (glomerulonephritis). Although Henoch-Schonlein purpura or anaphylactoid purpura, is thought to be a immune complex mediated disease, its exact cause is unknown. Its typical benign coarse can, however, include renal failure. (27 Sep 1997) |
| acute viral conjunctivitis | An epidemic inflammation of the conjunctiva marked by follicles, especially in the lower fornix; may be caused by adenoviruses, herpesvirus, and Newcastle disease virus. (05 Mar 2000) |
| acute yellow atrophy of the liver | A lesion in which there is extensive and rapid death of parenchymal cells of the liver, sometimes with fatty degeneration of the size of the organ; the necrosis may result from fulminant viral infection or chemical poisoning; associated with jaundice. Synonym: acute parenchymatous hepatitis, Rokitansky's disease. (05 Mar 2000) |
| bisectrix, acute | <microscopy> In biaxial crystals, that principal axis of the ellipsoid of indexes which bisects the smaller angle between the optic axes. (05 Aug 1998) |
| pancreatitis, acute necrotizing | Acute inflammation of the pancreas with areas of devitalised pancreatic and/or peripancreatic tissue. These necrotic areas may involve large areas of the pancreas or may be small. When a ct scan is performed with contrast media using a bolus technique, necrotic areas do not perfuse with media and are not enhanced. The lack of enhancement distinguishes necrotic tissue from the adjacent well-perfused viable pancreatic parenchyma. (12 Dec 1998) |
| retinal necrosis syndrome, acute | <ophthalmology> Mild to fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of retinal detachment and poor vision outcome. (12 Dec 1998) |
| common acute lymphoblastic leukaemia | <haematology, oncology> A sub-type of acute lymphoblastic leukaemia affecting cells early in the B lymphocyte lineage which accounts for about 80% of all acute lymphoblastic leukaemia. Origin: Gr. Haima = blood (13 Nov 1997) |
| conjunctivitis, acute haemorrhagic | A highly contagious disease characterised by subconjunctival haemorrhage, sudden swelling of the eyelids and congestion, redness, and pain in the eye. Epidemic conjunctivitis caused by enterovirus 70 (ev-70) was first described in africa in 1969. It is caused also by coxsackie virus a24 variant (ca24v). Epidemics by this organism have appeared most frequently in asia. (12 Dec 1998) |
| porphyria, acute intermittent | A form of hepatic porphyria (porphyria, hepatic) characterised by periodic attacks of gastrointestinal disturbances, abdominal colic, paralyses, and psychiatric disorders. The onset of this condition is usually in the third or fourth decade of life. (12 Dec 1998) |
| stricture, oesophagus, acute | A narrowing or closure of the normal opening of the swallowing tube leading to the stomach, usually caused by scarring from acid irritation. Acute, complete obstruction of the oesophagus occurs when food (usually meat) is lodged in the oesophageal stricture. Patients experience chest pain, and are unable to swallow saliva. Attempts to relieve the obstruction by inducing vomiting at home are usually unsuccessful. Patients with complete oesophageal obstruction can breathe, and are not at any risk of suffocation. Endoscopy is usually employed to retrieve the meat and relieve the obstruction. (12 Dec 1998) |
| diverticulitis, treatment of acute | Antibiotics are usually needed. Oral antibiotics are sufficient when symptoms are mild. Liquid or low fibre foods are advised during acute diverticulitis attacks. In severe diverticulitis with high fever and pain, patients are hospitalised and given intravenous antibiotics. Surgery is needed for persistent bowel obstruction or abscesses not responding to antibiotics. (12 Dec 1998) |
| illness, acute | An illness with an abrupt onset and usually a short course. (12 Dec 1998) |
