|---|---|
| osteitis condensans ilii | Symmetric benign osteosclerosis of the portion of the iliac bones adjacent to the sacroiliac joints. (05 Mar 2000) |
| osteitis deformans | This is a disease of bone that initially results in the excessive resorption of bone (by osteoclasts) followed by the replacement of normal bone marrow with vascular and fibrous tissue. Many patients are asymptomatic and diagnosed by routine X-rays. (27 Sep 1997) |
| osteitis fibrosa | <radiology> Secondary to hypocalcaemia and hyperphosphataemia followed by increased parathormone production, subperiosteal bone resorption, radial aspect of phalanges, distal clavicle, medial tibia plateau, medial humerus neck, distal ulna, phalangeal tufts, lamina dura of teeth, subchondral and subligamentous bone resorption, widening of symphysis pubis, SI joints, resorption of ischial tuberosity, spotty deossification of the skull (wooly, salt and pepper), metaphyseal fractures, slipped epiphyses, brown tumour and chondocalcinosis, more common in primary hyperparathyroidism see: renal osteodystrophy (12 Dec 1998) |
| osteitis fibrosa circumscripta | Fibrous dysplasia of a single bone. Synonym: localised osteitis fibrosa, osteitis fibrosa circumscripta. (05 Mar 2000) |
| osteitis fibrosa cystica | Rarefying osteitis with fibrous degeneration and formation of cysts, and with the presence of fibrous nodules on the affected bones. It is due to marked osteoclastic activity secondary to hyperfunction of the parathyroid glands. (12 Dec 1998) |
| osteitis fibrosa disseminata | The occurrence of lesions of fibrous dysplasia in multiple bones, commonly on one side of the body; may occur with areas of pigmentation and endocrine dysfunction (McCune-Albright syndrome). Synonym: multifocal osteitis fibrosa, osteitis fibrosa disseminata. (05 Mar 2000) |
| osteitis pubis | Osteosclerosis of the pubic bone next to the symphysis, caused by trauma to that region, from pregnancy or instrumentation. (05 Mar 2000) |
| localised osteitis fibrosa | Fibrous dysplasia of a single bone. Synonym: localised osteitis fibrosa, osteitis fibrosa circumscripta. (05 Mar 2000) |
| anterior focal point | The point where parallel rays from the retina are focused. (05 Mar 2000) |
| back focal length | <microscopy> As measured on the principal axis, from the second lens vertex to the back focal point of the lens. It is not the equivalent of the focal length. (05 Aug 1998) |
| back focal plane | <microscopy> The plane, normal to the lens axis, situated at the back focus of a lens. (05 Aug 1998) |
| Berger's focal glomerulonephritis | Glomerulonephritis affecting a small proportion of renal glomeruli which commonly presents with haematuria and may be associated with acute upper respiratory infection in young males, not usually due to streptococci; associated with IgA deposits in the glomerular mesangium and may also be associated with systemic disease, as in Henoch-Schonlein purpura. Synonym: Berger's disease, Berger's focal glomerulonephritis, focal nephritis, IgA nephropathy. (05 Mar 2000) |
| glomerulosclerosis, focal | Glomerular disease characterised by focal and segmental areas of glomerular sclerosis, usually commencing in the juxtamedullary glomeruli and gradually spreading to involve other parts of the kidney, with eventual kidney failure. (12 Dec 1998) |
| chronic focal sclerosing osteomyelitis | A reaction of bone to a mild bacterial infection, often the result of a carious tooth, in persons with a high degree of tissue resistance; results in a localised radio-opacity. Synonym: focal condensing osteitis. (05 Mar 2000) |
