| angioneurotic oedema | <neurology> An acute or recurring attack of transient oedema suddenly appearing in areas of the skin or mucous membranes and occasionally of the viscera, often associated with dermatographism, urticaria, erythema, and purpura. It can produce dramatic swelling of the subcutaneous tissues (welts beneath the skin) that typically appears around the eyes and lips. Welts may also involve the hands, feet and throat (compromise the airway). This condition is associated with allergies (for example foods, pollen), but may also be a side effect of some medications (for example ACE inhibitors, salicylates). Emotional stress, exposure to cold, water, sunlight, heat and insect bites all have been know to cause angioneurotic oedema. Treatment is with adrenaline, antihistamines, cimetidine, and/or corticosteroids. (12 Dec 1998) |
| angioneurotic oedema, hereditary | 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) |
