| rheumatism | <medicine> A general disease characterised by painful, often multiple, local inflammations, usually affecting the joints and muscles, but also extending sometimes to the deeper organs, as the heart. <medicine> Inflammatory rheumatism, acute rheumatism attended with fever, and attacking usually the larger joints, which become swollen, hot, and very painful. Rheumatism root. <botany> See Twinleaf. Origin: L. Rheumatismus rheum, Gr, fr. To have or suffer from a flux, fr. Rheum: cf. F. Rheumatisme. See 2d Rheum. Source: Websters Dictionary (01 Mar 1998) |

| rheumatoid arteritis | Coronary arteritis associated with rheumatoid arthritis; aortitis with aortic valve incompetence accompanying ankylosing spondylitis may be related. (05 Mar 2000) |
| rheumatoid arthritis | <rheumatology> Chronic inflammatory disease in which there is destruction of joints. Considered by some to be an autoimmune disorder in which immune complexes are formed in joints and excite an inflammatory response (complex mediated hypersensitivity). Cell-mediated (type IV) hypersensitivity also occurs and macrophages accumulate. This in turn leads to the destruction of the synovial lining (see pannus). (18 Nov 1997) |
| rheumatoid arthritis, systemic-onset juvenile | Also known as systemic-onset juvenile chronic arthritis. Still's disease presents with systemic (bodywide) illness including high intermittent fever, a salmon-coloured skin rash, swollen lymph glands, enlargement of the liver and spleen, and inflammation of the lungs (pleuritis) and around the heart (pericarditis). The arthritis may not be immediately apparent but it does appear and may persist after the systemic symptoms are gone. (12 Dec 1998) |
| rheumatoid arthritis: joint manifestations | <radiology> Early signs: fusiform periarticular soft tissue swelling (result of effusion), regional osteoporosis (disuse and local hyperaemia), widened joint space, marginal and central bone erosion (base of 4th proximal phalanx most common), change in ulnar styloid and distal radioulnar joint, atlantoaxial dislocation, giant synovial cysts late signs: flexion/extension contractures with ulnar subluxation/dislocation, destruction/fusion of joints, elevation of humeral heads (tear/atrophy of rotator cuff), resorption of distal clavicle, erosion of superior margins of posterior portions of 3-5th ribs, destruction/narrowing of disc spaces, destruction of zygapophyseal joints without osteophyte formation, resorption of spinous process, protrusio acetabuli (from osteoporosis) (12 Dec 1998) |
| rheumatoid disease | Rheumatoid arthritis, referring particularly to nonarticular lesions such as subcutaneous nodules. (05 Mar 2000) |
| rheumatoid factor | Complex of IgG and anti-igG formed in joints in rheumatoid arthritis. Serum rheumatoid factors are more usually formed from IgM antibodies directed against IgG. (18 Nov 1997) |
| rheumatoid factors | Antibodies in the serum of individuals with rheumatoid arthritis that react with antigenic determinants or immunoglobulins that enhance agglutination of suspended particles coated with pooled human gamma-globulin. Rheumatoid factors also occur in other autoimmune and certain infectious diseases. (05 Mar 2000) |
| rheumatoid lung disease | <radiology> Pleural effusion, most common finding, seen mostly in males (although RA more common in females), diffuse interstitial fibrosis, necrobiotic nodules, Caplan syndrome, nodules and pneumoeritis and hypertension (12 Dec 1998) |
