| liver diseases, parasitic | Infections of the liver with a parasite. They are caused most commonly by trematodes (flukes). (12 Dec 1998) |
|---|---|
| lung diseases, interstitial | A heterogeneous group of noninfectious, nonmalignant disorders of the lower respiratory tract, affecting primarily the alveolar wall structures but also often involving the small airways and blood vessels of the lung parenchyma. "interstitial" refers to the fact that the interstitium of the alveolar walls is thickened, usually by fibrosis. This group of diseases is usually inflammatory. (12 Dec 1998) |
| lung diseases, obstructive | Any disorder marked by persistent obstruction of bronchial air flow. (12 Dec 1998) |
| lung diseases, parasitic | Infections of the lungs with a parasite. They are caused most commonly by nematodes (roundworms). (12 Dec 1998) |
| lymphatic diseases | Diseases of lymph or lymph vessels. (12 Dec 1998) |
| lysosomal diseases | Diseases (also called storage diseases) in which a deficiency of a particular lysosomal enzyme leads to accumulation of the undigested substrate for that enzyme within cells. Not immediately fatal, but within a few years lead to serious neurological and skeletal disorders and eventually to death. See: the following conditions: Hurler sundrome, Hunter syndrome, San Fillipo, Gaucher's disease, Niemann-Pick, Pompe's disease, Tay Sachs disease. (18 Nov 1997) |
| lysosomal storage diseases | Inborn errors of metabolism characterised by defects in specific lysosomal hydrolases and resulting in intracellular accumulation of unmetabolised substrates. (12 Dec 1998) |
| 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) |
| air-bone gap | The difference between the threshold for hearing acuity by bone conduction and by air conduction. (05 Mar 2000) |
| Albrecht's bone | A small bone between the basioccipital and basisphenoid. (05 Mar 2000) |
| allogeneic bone marrow transplant | <haematology, procedure> A bone marrow transplant using marrow collected from a matched healthy donor, usually a brother or sister. The risks associated with the transplant increase with age and 50 years of age is generally regarded as the upper limit. (13 Nov 1997) |
| alveolar bone | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| alveolar bone loss | The resorption of bone in the supporting structures of the maxilla or mandible as a result of periodontal disease. (12 Dec 1998) |
| alveolar supporting bone | alveolar process |
| amyloidosis: bone manifestations | <radiology> Joint pain without radiographic findings, osteoporosis, especially in axial skeleton, lytic lesions that destroy cortex and invade soft tissue, wrist, scaphoid and lunate lesions that may extend into the carpal tunnel, inducing the classic complaints of carpal tunnel syndrome amyloid arthropathy Differential diagnosis: pigmented villonodular synovitis, synovial chondromatosis, rheumatoid arthritis, TB (12 Dec 1998) |
