| Leber's idiopathic stellate neuroretinitis | A unilateral neuroretinitis with perifoveal exudates in Henle's nerve fibre layer producing a macular star and spontaneous regression in a few months. Synonym: Leber's idiopathic stellate neuroretinitis. (05 Mar 2000) |
|---|---|
| Leber's idiopathic stellate retinopathy | An inflammation affecting the optic nerve head and the posterior pole of the retina, with cells in the nearby vitreous, usually producing a macular star. Synonym: papilloretinitis. (05 Mar 2000) |
| 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) |
| arthritis nodosa | <disease> 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. (11 Nov 1997) |
