| rheumatic endocarditis | Endocardial involvment as part of rheumatic heart disease, recognised clinically by valvular involvement; in the acute stage, there may be tiny fibrin vegetations along the lines of closure of the valve leaflets, with subsequent fibrous thickening and shortening of the leaflets. (05 Mar 2000) |
|---|---|
| rheumatic fever | <microbiology> Disease involving inflammation of joints and damage to heart valves that follows streptococcal infection and is believed to be autoimmune, i.e. Antibodies to streptococcal components cross react with host tissue antigens. (18 Nov 1997) |
| rheumatic heart disease | The most important manifestation of and sequel to rheumatic fever, i.e., any cardiac involvement in rheumatic fever. (12 Dec 1998) |
| rheumatic nodule | A small round or oval, mostly subcutaneous nodule made up chiefly of a mass of aschoff bodies and seen in cases of rheumatic fever. It is differentiated from the rheumatoid nodule which appears in rheumatoid arthritis, most frequently over bony prominences. (12 Dec 1998) |
| rheumatic pericarditis | Fibrinous pericarditis occurring in acute rheumatic fever. (05 Mar 2000) |
| rheumatic pneumonia | Pneumonia rarely occurring in severe acute rheumatic fever, even when the disease was common; consolidation occurs, the lungs being of a rubbery consistency, with fibrin exudate and small haemorrhages, as well as oedema from left ventrical failure. (05 Mar 2000) |
| rheumatic tetany | An acute epidemic form of tetany, of several weeks' duration, occurring chiefly in winter. Synonym: epidemic tetany. (05 Mar 2000) |
| rheumatic torticollis | Stiff neck due to cervical or neck myositis, chiefly of the sternocleidomastoid, occurring especially in children. Synonym: rheumatic torticollis. (05 Mar 2000) |
| rheumatic valvulitis | Valvulitis characterised in the acute stage by small fibrin vegetations along the lines of closure and by Aschoff bodies in the cusps; in the chronic stage, it is characterised by scarring, commissural adhesion, and stenosis and/or regurgitation. (05 Mar 2000) |
| aqueductal stenosis | <radiology> most common cause of congenital hydrocephalus (43%), aqueduct develops about the 6th week of gestation, M:F = 2:1, other congenital anomalies (16%): thumb deformities, prognosis: 11-30% mortality aetiology: infectious (50%): toxoplasmosis, CMV, syphillis, mumps, influenza, developmental: forking, narrowing, transverse septum (X-linked recessive), neoplastic (extremely rare): glioma, pinealoma, meningioma (12 Dec 1998) |
| buttonhole stenosis | Extreme narrowing, usually of the mitral valve. (05 Mar 2000) |
| carotid stenosis | The narrowing or stricture of a carotid artery that may lead to transient ischemic attacks (see cerebral ischemia, transient) and stroke (see cerebrovascular disorders). (12 Dec 1998) |
| renal artery stenosis | <cardiology, nephrology> A narrowing of the renal artery or one of its main branches accounts for 2 to 5% of cases of hypertension. (27 Sep 1997) |
| mitral stenosis | <cardiology> A congenital or acquired heart valve abnormality that describes the narrowing and ineffective opening of the mitral valve. (13 Nov 1997) |
| mitral valve stenosis | A rheumatic disease causing diffuse thickening of the mitral valve leaflets by fibrous tissue or calcific deposits. (harrisons' principles of internal medicine, 13th ed, p1052) (12 Dec 1998) |
