| oedema, hereditary angioneurotic | A genetic form of angioedema. (Angioedema is also referred to as Quinke's disease.) Persons with it are born lacking an inhibitor protein (called C1 esterase inhibitor) that normally prevents activation of a cascade of proteins leading to the swelling of angioedema. Patients can develop recurrent attacks of swollen tissues, pain in the abdomen, and swelling of the voice box (larynx) which can compromise breathing. The diagnosis is suspected with a history of recurrent angioedema. It is confirmed by finding abnormally low levels of C1 esterase inhibitor in the blood. Treatment options include antihistamines and male steroids (androgens) that can also prevent the recurrent attacks. Also called hereditary angioedema. (12 Dec 1998) |
| oedema neonatorum | A diffuse, firm, and commonly fatal oedema occurring in the newborn, usually beginning in the legs and spreading upward. (05 Mar 2000) |
| Yangtze oedema | <dermatology, microbiology> A migrating oedema, or creeping eruption, caused by cutaneous infection by larvae of Gnathostoma spinigerum. Synonym: Yangtze oedema. (05 Mar 2000) |
| laryngeal oedema | Oedema of any region of the larynx from a variety of causes. In the earliest stages it may be difficult to differentiate from infection, although mucosal injection and erythema are found more often in the latter. Allergic oedema may result as a response from provocation induced by foods, inhalants, and drugs. The entire respiratory tract or only an isolated portion of the larynx may be affected. Laryngeal oedema may also be hereditary. Other possible causes of laryngeal oedema include increased capillary pressure due to superior vena cava syndrome, internal jugular vein ligation, lowered plasma osmotic failure induced by renal failure, impaired lymphatic flow, and increased capillary permeability to proteins.

| lymphatic oedema | Oedema due to stasis in the lymph channels. Synonym: leukophlegmasia. (05 Mar 2000) |
