| hereditary peroneal nerve dysfunction | <neurology> A slowly progressive genetic disorder characterised by muscle atrophy in the feet and the legs, progressing to the hands and arms, due to a disorder involving the destruction of nerves (degeneration of the myelin sheath). Other features include foot drop and a slapping gait. There is no specific treatment for this disorder. (27 Sep 1997) |
|---|---|
| psychosexual dysfunction | Sexual dysfunction, a disturbance of sexual functioning, e.g., impotence, premature ejaculation, anorgasmia, presumed to be of psychological rather than physical aetiology. (05 Mar 2000) |
| sphincter of Oddi dysfunction | Structural or functional abnormality of the sphincter of Oddi that interferes with bile drainage. Synonym: biliary dyskinesia. (05 Mar 2000) |
| dental dysfunction | <dentistry> Abnormal functioning of dental structures. (05 Mar 2000) |
| dysfunction | Disturbance, impairment or abnormality of the functioning of an organ. (18 Nov 1997) |
| dysfunction, erectile | A consistent inability to sustain an erection sufficient for sexual intercourse. Also commonaly known as impotence. Medically, the term erectile dysfunction is used to differentiate impotence from other problems that interfere with sexual intercourse (such as lack of sexual desire and problems with ejaculation and orgasm). Impotence usually has a physical cause, such as disease, injury, drug side-effects, or a disorder that impairs blood flow in the penis. Impotence is treatable in all age groups. (12 Dec 1998) |
| temporomandibular joint dysfunction | Chronic or impaired function of the temporomandibular articulation. See: temporomandibular arthrosis, myofacial pain-dysfunction syndrome. (05 Mar 2000) |
| temporomandibular joint dysfunction syndrome | <syndrome> A symptom complex consisting of pain, muscle tenderness, clicking in the joint, and limitation or alteration of mandibular movement. The symptoms are subjective and manifested primarily in the masticatory muscles rather than the temporomandibular joint itself. Aetiologic factors are uncertain but include occlusal dysharmony and psychophysiologic factors. (12 Dec 1998) |
| temporomandibular joint pain-dysfunction syndrome | <syndrome> Dysfunction of the masticatory apparatus related to spasm of the muscles of mastication precipitated by occlusal dysharmony or alteration in vertical dimension of the jaws, and exacerbated by emotional stress; characterised by pain in the preauricular region, muscle tenderness, popping noise in the temporomandibular joint, and limitation of jaw motion. Synonym: temporomandibular joint pain-dysfunction syndrome. (05 Mar 2000) |

| antigens, differentiation, b-lymphocyte | Membrane antigens associated with maturation stages of B-lymphocytes, often expressed in tumours of B-cell origin. (12 Dec 1998) |
| antigens, differentiation, t-lymphocyte | Antigens expressed on the cell membrane of T-lymphocytes during differentiation, activation, and normal and neoplastic transformation. Their phenotypic characterization is important in differential diagnosis and studies of thymic ontogeny and T-cell function. (12 Dec 1998) |
| bare lymphocyte syndrome | <syndrome> Absence of HLA antigens on peripheral mononuclear cells, which may result in immunodeficiency. (05 Mar 2000) |
| B lymphocyte | <haematology, immunology> An immunologically important lymphocyte, produced by the bone marrow, that is responsible for the production of immunoglobulins, it is the precursor of the plasma cell. The surface markers can be used to detect and differentiate chronic lymphocytic leukaemia from acute lymphocytic leukaemia. (13 Nov 1997) |
| b-lymphocyte subsets | A classification of B-lymphocytes based on structurally or functionally different populations of cells. (12 Dec 1998) |
