| psoriatic arthritis | <radiology> Types: true psoriatic arthritis (1/3), resembling rheumatoid arthritis (1/3), combination of psoriatic and RA (1/3) findings: no juxta-articular osteoporosis (unlike RA), periosteal reaction frequent, assymetrical destruction of DIP with ankylosis, resorption of terminal tufts with pencil in cup deformity, ivory phalanx, destruction of 1st toe IP joint with periosteal reaction and bony proliferation at distal phalangeal base (pathognomonic), assymetrical syndesmophytes (lower C- to upper lumbar spine), squaring of vertebrae in lumbar spine, paravertebral soft tissue calcifications, bilateral assymetrical sacroiliitis associated with HLA B-27 antigen, negative rheumatoid factor (12 Dec 1998) |
|---|---|
| septic arthritis | <pathology> A pus-forming bacterial infection of a joint space. Symptoms include a hot, swollen, red joint, that is very tender to any attempted movement. (27 Sep 1997) |
| pyogenic arthritis | Acute inflammation of synovial membranes, with purulent effusion into a joint, due to bacterial infection; the usual route of infection is hemic to the synovial tissue, causing destruction of the articular cartilage, and may become chronic, with sinus formation, osteomyelitis, deformity, and disability. Synonym: purulent synovitis, pyarthrosis, pyogenic arthritis, suppurative synovitis. (05 Mar 2000) |
| hypertrophic arthritis | <pathology> Noninflammatory degenerative joint disease occurring chiefly in older persons, characterised by degeneration of the articular cartilage, hypertrophy of bone at the margins and changes in the synovial membrane. It is accompanied by pain and stiffness, particularly after prolonged activity. Origin: Gr. Arthron = joint (18 Nov 1997) |
| neonatal arthritis of foals | Bacterial polyarthritis caused by umbilical infections by several bacterial species. (05 Mar 2000) |
| neuropathic arthritis | <radiology> M more than F, age more than 40 yrs, 6 D's, destruction, increased density, dislocation, debris, distension, disorganization, diabetic neuropathy, syphilis (tabes dorsalis), syrinx, meningomyelocele / spina bifida, nerve injury: spinal cord or peripheral nerves, congenital insensitivity to pain, leprosy, Charcot-Marie-Tooth syndrome (12 Dec 1998) |
| suppurative arthritis | Acute inflammation of synovial membranes, with purulent effusion into a joint, due to bacterial infection; the usual route of infection is hemic to the synovial tissue, causing destruction of the articular cartilage, and may become chronic, with sinus formation, osteomyelitis, deformity, and disability. Synonym: purulent synovitis, pyarthrosis, pyogenic arthritis, suppurative synovitis. (05 Mar 2000) |
| degenerative arthritis | <pathology> A form of arthritis that results in the destruction of the articular cartilage that line the joints. Seen predominately in the larger weight bearing joints of the hips, knees and spine, but may also be evident in the small joints of the hands. (27 Sep 1997) |
| dermatitis-arthritis-tenosynovitis syndrome | <syndrome> Disseminated infection with Neisseria gonorrhoeae, causing skin lesions (often pustular or necrotic), plus synovitis of major joints (such as knee, ankle, elbow), and tendon sheaths. (05 Mar 2000) |
| ochronotic arthritis | Osteoarthritis occurring as a complication of ochronosis. (05 Mar 2000) |
| elbow, arthritis of the | Inflammation (arthritis) of the elbow joint can be due to many systemic forms of arthritis, including rheumatoid arthritis, gouty arthritis, psoriatic arthritis, ankylosing spondylitis, and Reiter's disease. Generally, they are associated with signs of inflammation of the elbow joint, including heat, warmth, swelling, pain, tenderness, and decreased range of motion. Range of motion of the elbow is decreased with arthritis of the elbow because the swollen joint impedes the range of motion (12 Dec 1998) |
| enteropathic arthritis | A form of arthritis sometimes resembling rheumatoid arthritis which may complicate the course of ulcerative colitis, Crohn's disease, or other intestinal disease. (05 Mar 2000) |
| Jaccoud's arthritis | A rare form of chronic arthritis, reported to occur after attacks of acute rheumatic fever, characterised by an unusual form of bone erosion of the metacarpal heads and by ulnar deviation of the fingers; it resembles rheumatoid arthritis, but with less overt inflammation, and rheumatoid factor is absent. Synonym: Jaccoud's arthropathy. (05 Mar 2000) |
| 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) |
