| juvenile rheumatoid arthritis | <pathology> Juvenile rheumatoid arthritis (JRA) is a form of rheumatoid arthritis in children that generally occurs prior to age 16. In contrast with the adult type, a fever is more pronounced. Cardiac involvement with pericarditis is more common. The arthritis favors one or more large joints and can interfere with normal bone growth. A positive rheumatoid factor is seen more uncommonly in this form of arthritis. Treatment is similar to the adult form of the disease. Up to 75% recover with treatment. Less than 10% are severely disabled by JRA. (27 Sep 1997) |
| juvenile rheumatoid arthritis, systemic-onset | 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 always surface and it may persists long after the systemic symptoms are gone. (12 Dec 1998) |
| filarial arthritis | Arthritis occurring in filariasis, probably due to extravasation of lipid-rich lymph resembling chyle into the joint space. (05 Mar 2000) |
| fungal arthritis | <pathology, rheumatology> Infection of a joint space by fungus. Common fungi that can cause mycotic arthritis include coccidioidomycosis, histoplasmosis, blastomycosis, cryptococcosis, sporotrichosis and candidiasis. Infection of a joint generally occurs as a result of a primary fungal infection in the lungs. Treatment is with antifungal agents (for example amphotericin B, ketoconazole). (27 Sep 1997) |
| lyme arthritis | <radiology> Migratory polyarthritis, common in New England (named for Lyme, Conn.), spirochete (Borrelia) transmitted by tick (Ixodes dammini), joint effusion, especially knee (may be only finding), skin lesions: erythema chronicum migrans (12 Dec 1998) |
