| rheumatoid nodules | rheumatoid nodules are firm lumps in the skin of patients with rheumatoid arthritis that usually occur in pressure points of the body, most commonly the elbows (12 Dec 1998) |
|---|---|
| rheumatoid spondylitis | <rheumatology> A polyarthritis involving the spine, which is characterised by progressive, painful stiffening of the joints and ligaments. It almost exclusively affects young men. Interestingly the disease seems to be associated with HLA B27, those with this histocompatability antigen are 300 times more likely to get the disease, 90% of sufferers have HLA B27 (18 Nov 1997) |
| factor, rheumatoid | Rheumatoid factor is an antibody that is measurable in the blood. It is commonly used as a blood test for the diagnosis of rheumatoid arthritis. Rheumatoid factor is present in about 80% of adults (but a much lower proportion of children) with rheumatoid arthritis. It is also present in patients with other connective tissue diseases (such as systemic lupus erythematosus) and in some with infectious diseases (such as infectious hepatitis). (12 Dec 1998) |
| acute rheumatic arthritis | Arthritis due to rheumatic fever. (05 Mar 2000) |
| arthritis | <rheumatology> An inflammatory condition that affects joints. Can be infective, autoimmune, traumatic in origin. Origin: Gr. Arthron = joint (18 Nov 1997) |
| arthritis, adjuvant | An arthritis experimentally induced in animals with freund's adjuvant. (12 Dec 1998) |
| arthritis deformans | A systemic disease, seen more commonly in women which affects connective tissue, particularly the synovial tissue within joints. Arthritis is the main clinical feature and involves many joints in the body, especially those of the hand and feet. In this disease, there is thickening of the soft tissues around the joints and extension of the synovial tissue over articular cartilage (which becomes eroded). A chronic and progressive course is common with joint deformities and disability. Juvenile rheumatoid arthritis is a variant which affects children. (27 Sep 1997) |
| arthritis, degenerative | A type of arthritis caused by inflammation, breakdown, and eventual loss of the cartilage of the joints. Also called osteoarthritis. (12 Dec 1998) |
| arthritis-encephalitis virus, caprine | A species of lentivirus, subgenus ovine-caprine lentiviruses (lentiviruses, ovine-caprine), closely related to visna-maedi virus and causing acute encephalomyelitis, chronic arthritis, pneumonia, mastitis, and glomerulonephritis in goats. It is transmitted mainly in the colostrum and milk. (12 Dec 1998) |
| arthritis, gout | Joint inflammation caused by uric acid crystal deposits in the joint space An attack is usually extremely painful.The uric acid crystals are deposited in the joint fluid (synovial fluid) and joint lining (synovial lining). Intense joint inflammation occurs as white blood cells engulf the uric acid crystals, causing pain, heat, and redness of the joint tissues. The term gout commonly is used to refer to these painful arthritis attacks but gouty arthritis is only one manifeatation of gout. (12 Dec 1998) |
| arthritis, gouty | Arthritis, especially of the great toe, as a result of gout. Acute gouty arthritis often is precipitated by trauma, infection, surgery, etc. The initial attacks are usually monoarticular but later attacks are often polyarticular. (12 Dec 1998) |
| arthritis in children | Arthritis is not just a problem for the retired. It can and does affect children in the form of juvenile/paediatric arthritis. (12 Dec 1998) |
| arthritis, infectious | Arthritis caused by bacteria, rickettsiae, mycoplasmas, viruses, fungi, or parasites. Bacterial arthritis is frequently caused by staphylococcus aureus, streptococcus pneumoniae, haemophilus influenzae, and neisseria gonorrhoeae. Viral arthritis is less common than bacterial arthritis and may be a manifestation of such viral diseases as mumps, rubella, hepatitis, etc. (12 Dec 1998) |
| arthritis, lyme | Inflammation of the joints associated with Lyme disease, a bacterial disease spread by ticks. (12 Dec 1998) |
| arthritis mutilans | A form of chronic rheumatoid arthritis in which osteolysis occurs with extensive destruction of the joint cartilages and bony surfaces with pronounced deformities, chiefly of the hands and feet; similar changes can occur in some cases of psoriatic arthritis. (05 Mar 2000) |
