| juvenile spinal muscular atrophy | Slowly progressive proximal muscular weakness and wasting, beginning in childhood, caused by degeneration of motor neurons in the anterior horns of the spinal cord; onset usually between 2 and 17 years of age; usually autosomal recessive inheritance. Synonym: juvenile muscular atrophy, Kugelberg-Welander disease, Wohlfart-Kugelberg-Welander disease. (05 Mar 2000) |
|---|---|
| familial spinal muscular atrophy | Transmitted as autosomal recessive on chromosome 5q. Progressive dysfunction of the anterior horn cells in the spinal cord and brainstem cranial nerves with profound weakness and bulbar dysfunction occurring in the first two years of life. Three groups, based on age of clinical onset, are recognised. Synonym: familial spinal muscular atrophy, Hoffmann's muscular atrophy, infantile muscular atrophy, infantile progressive spinal muscular atrophy, progressive infantile spinal muscular atrophy, Werdnig-Hoffmann disease, Werdnig-Hoffmann muscular atrophy. (05 Mar 2000) |
| acute reflex bone atrophy | Atrophy of bones, commonly of the carpal or tarsal bones, following a slight injury such as a sprain. See: causalgia, reflex sympathetic dystrophy. Synonym: acute reflex bone atrophy, posttraumatic osteoporosis, Sudeck's syndrome. Origin: L. English sweat (05 Mar 2000) |
| acute yellow atrophy of the liver | A lesion in which there is extensive and rapid death of parenchymal cells of the liver, sometimes with fatty degeneration of the size of the organ; the necrosis may result from fulminant viral infection or chemical poisoning; associated with jaundice. Synonym: acute parenchymatous hepatitis, Rokitansky's disease. (05 Mar 2000) |
| adult pseudohypertrophic muscular dystrophy | Muscular dystrophy of late onset, often in the second or third decade, with relatively mild course; X-linked recessive inheritance; perhaps allelic with Duchenne's dystrophy, but milder and not a genetic lethal. Compare: Duchenne dystrophy. Synonym: Becker type tardive muscular dystrophy. (05 Mar 2000) |
| alveolar atrophy | Diminution in size of the supportive tissues of the teeth due to lack of function, reduced blood supply, or unknown causes. (05 Mar 2000) |
| arthritic atrophy | Atrophy of muscles rendered inactive by a chronically inflamed or fixed joint. (05 Mar 2000) |
| atrophy | <pathology> A wasting away, a diminution in the size of a cell, tissue, organ or part. Origin: L., Gr. Atrophia (16 Dec 1997) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| Becker's muscular dystrophy | An X-linked inherited disorder characterised by slowly progressive muscle weakness of the legs and pelvis. Other symptoms and findings include increased difficulty walking, intellectual retardation, fatigue and pseudohypertrophy of the calf muscles. (27 Sep 1997) |
| Becker type muscular dystrophy | A muscular dystrophy that has many of the clinical features of Duchenne muscular dystrophy e.g., symmetrical involvement of first the pelvicrural muscles and then the pectoral girdle and proximal upper extremity muscles; pseudohypertrophy, especially of the calf muscles but with a much later age of onset (35-45 years), and more benign course. X-linked inheritance. (05 Mar 2000) |
| Becker type tardive muscular dystrophy | Muscular dystrophy of late onset, often in the second or third decade, with relatively mild course; X-linked recessive inheritance; perhaps allelic with Duchenne's dystrophy, but milder and not a genetic lethal. Compare: Duchenne dystrophy. Synonym: Becker type tardive muscular dystrophy. (05 Mar 2000) |
| benign pseudohypertrophic muscular dystrophy | <neurology> An X-linked inherited disorder characterised by slowly progressive muscle weakness of the legs and pelvis. Other symptoms and findings include increased difficulty walking, intellectual retardation, fatigue and pseudohypertrophy of the calf muscles. (06 Aug 1998) |
| blue atrophy | Depressed blue atrophic scars due to injections in the skin of impure substances, as seen in narcotics addicts. (05 Mar 2000) |
| brown atrophy | Atrophy of the heart wall, especially in the elderly, in which the muscle is dark reddish brown and reduced in volume; the muscle fibres become pigmented especially about the nuclei, by lipochrome granules. (05 Mar 2000) |
