| 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, juvenile rheumatoid | Rheumatoid arthritis of children occurring in three major subtypes defined by the symptoms present during the first six months following onset: systemic-onset (still's disease, juvenile-onset) polyarticular-onset, and pauciarticular-onset. Adult-onset cases of still's disease (still's disease, adult-onset) are also known. Only one subtype of juvenile rheumatoid arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.

| 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) |
| arthritis, psoriatic | Joint inflammation associated with psoriasis. (12 Dec 1998) |
| arthritis, quackery | Like many people with chronic ailments, sufferers from arthritis are potentially vulnerable to proponents of cure-all treatments which are promoted as having great benefits, but in reality have no right to such claims. (12 Dec 1998) |
| arthritis, reactive | An abacterial form of arthritis developing after infection at a site distant from the affected joint or joints. The causative bacteria cannot be cultured from synovial specimens but bacterial antigens have been demonstrated in cells from the synovial fluid and membrane. It often follows yersinia infection. (12 Dec 1998) |
| arthritis, reiter's | The combination of inflammation of the joints (arthritis), eyes (conjunctivitis), and GU (genitourinary) &/or GI (gastrointestinal) systems. (12 Dec 1998) |
| arthritis, rheumatoid | Autoimmune disease that is characterised by chronic inflammation of the joints and can cause inflammation of tissues in other areas of the body (such as the lungs, heart, and eyes). (12 Dec 1998) |
| arthritis, spondylitis | A form of arthritis causing chronic inflammation of the spine. (12 Dec 1998) |
| atrophic arthritis | An obsolete term for arthritis without new bone formation, now usually called rheumatoid arthritis. (05 Mar 2000) |

| caprine arthritis-encephalomyelitis | A worldwide disease of goats caused by the caprine arthritis-encephalomyelitis virus; two syndromes are recognised, encephalomyelitis in kids and more commonly arthritis in adults. (05 Mar 2000) |
| caprine arthritis-encephalomyelitis virus | A lentivirus causing caprine arthritis-encephalomyelitis in goats. (05 Mar 2000) |
