| acute porphyria | <gastroenterology, haematology> A group of metabolic disorders that result from a disturbance in porphyrin metabolism, causing increased formation and excretion of porphyrin or its precursors. Acute intermittent porphyria is a rare inherited (autosomal dominant) form that can result in abdominal pain, photosensitivity and neurological disturbances. The various forms can be differntiated measuring various blood prophyrins. (27 Sep 1997) |

| acute post-streptococcal glomerulonephritis | <nephrology> A disease of the kidneys that results in inflammation of the glomerulus (the portion of the kidney that filters the blood). Conditions which may cause glomerulonephritis include post-streptococcal disease (strep throat), lupus, syphilis, bacterial endocarditis, membranoproliferative glomerulonephritis, sepsis, vasculitis, Goodpasture's syndrome, typhoid fever, Henoch-Schonlein purpura, hepatitis or a viral infection (for example mumps, measles, mononucleosis). (27 Sep 1997) |
| acute primary haemorrhagic meningoencephalitis | A disease characterised by acute onset of fever, followed by convulsions, delirium, and coma, and associated with perivascular demyelination and haemorrhagic foci in the central nervous system. Synonym: acute primary haemorrhagic meningoencephalitis, Strumpell's disease. (05 Mar 2000) |
| acute promyelocytic leukaemia | Leukaemia presenting as a severe bleeding disorder, with infiltration of the bone marrow by abnormal promyelocytes and myelocytes, a low plasma fibrinogen, and defective coagulation. (05 Mar 2000) |
| acute pulmonary alveolitis | Acute inflammation involving exudate into the pulmonary alveoli and impaired gas exchange; may result in necrosis with haemorrhage into the lungs; occurs in Goodpasture's syndrome, in association with a glomerulonephritis. (05 Mar 2000) |
| acute pulmonary eosinophilia | <chest medicine> A self-limiting inflammation in the lungs where there is associated infiltration of eosinophils into lung tissue. Chest X-ray reveals pulmonary infiltrates and full blood count shows increased numbers of eosinophils. The cause is unknown and the disease often resolves without treatment. Some forms may be treated with oral corticosteroids. Complications include restrictive cardiomyopathy due to fibrosis of the lining of the heart. (27 Sep 1997) |
| acute pyelonephritis | Acute inflammation of the renal parenchyma and pelvis characterised by small cortical abscesses and yellowish streaks in the medulla due to pus in the collecting tubules and interstitial tissue. (05 Mar 2000) |
| acute radiation syndrome | <syndrome> A syndrome caused by exposure of the body to large amounts of radiation, (e.g., from certain forms of therapy, accidents, and nuclear explosions; it is divided into three major forms which are, in ascending order of severity, the haematogic, gastrointestinal, and central nervous system-cardiovascular forms; its clinical manifestations are divided into prodromal, latent, overt, and recovery stages. (05 Mar 2000) |
| acute reflex bone atrophy | Atrophy of bones, commonly of the carpal or tarsal bones, following a slight injury such as a sprain. See: causalgia, reflex sympathetic dystrophy. Synonym: acute reflex bone atrophy, posttraumatic osteoporosis, Sudeck's syndrome. Origin: L. English sweat (05 Mar 2000) |
| acute rejection | Graft rejection which usually begins within 10 days after a graft has been transplanted into a genetically dissimilar host. Lesions at the site of the graft characteristically are infiltrated with large numbers of lymphocytes and macrophages which cause tissue damage. See: primary rejection. Synonym: acute rejection. (05 Mar 2000) |
| acute renal failure | <nephrology> A sudden decline in renal function may be triggered by a number of acute disease processes. Examples include sepsis (infection), shock, trauma, kidney stones, kidney infection, drug toxicity (aspirin or lithium), poisons or toxins (drug abuse) or after injection with an iodinated contrast dye (adverse effect). Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anaemia. Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
| acute respiratory failure | Loss of pulmonary function either acute or chronic that results in hypoxaemia or hypercarbia. (05 Mar 2000) |
| acute rheumatic arthritis | Arthritis due to rheumatic fever. (05 Mar 2000) |
| acute rhinitis | An acute catarrhal inflammation of the mucous membrane of the nose, marked by sneezing, lacrimation, and a profuse secretion of watery mucus; usually associated with infection by one of the common cold viruses. Synonym: cold in the head, coryza. (05 Mar 2000) |
| acute rickets | Bone changes seen in infantile scurvy, consisting of subperiosteal haemorrhage and deficient osteoid tissue formation; often used to indicate simultaneous occurrence of rickets and scurvy. Synonym: acute rickets. Hereditary hypophosphatemic rickets, with hypercalciuria, an inherited disorder in which there is a defect in renal tubular reabsorption. (05 Mar 2000) |
| acute renal failure |
Acute renal failure (ARF) is a rapid loss of renal function resulting in retention of nitrogenous (urea and creatinine)and non nitrogenous waste products. Depending on the severity and duration of the renal dysfunction, this accumulationis accompanied by metabolic disturbances, such as metabolic acidosis and hyperkalaemia, changes in body fluid balance, and effects on many other organ systems. It can be characterised by oliguria (although an- or nonoliguric ARF can occur). ...

| acute angle |
An angle (from the Lat. angulus, a corner, a diminutive, of which the primitive form, angus, does not occur in Latin; cognate are the Lat. angere, to compress into a bend or to strangle, and the Gr. ἄγκοσ, a bend; both connected with the Aryan or Indo-European root ank-, to bend) is the figure formed by two rays sharing a common endpoint, called the vertex of the angle. ...
