| oedema | <clinical sign> The presence of abnormally large amounts of fluid in the intercellular tissue spaces of the body, usually applied to demonstrable accumulation of excessive fluid in the subcutaneous tissues. Oedema may be localised, due to venous or lymphatic obstruction or to increased vascular permeability or it may be systemic due to heart failure or renal disease. Collections of oedema fluid are designated according to the site, for example ascites (peritoneal cavity), hydrothorax (pleural cavity) and hydropericardium (pericardial sac). Massive generalised oedema is called anasarca. Origin: Gr. Oide ma = swelling (18 Nov 1997) |

| oedema disease | An acute, highly fatal disease of young pigs caused by toxins of the bacterium Escherichia coli and characterised by oedema of various parts of the body but particularly the walls of the gastrointestinal tract. (05 Mar 2000) |
| oedema disease of swine | An acute disease of young pigs that is usually associated with weaning. It is characterised clinically by paresis and subcutaneous oedema. (12 Dec 1998) |

| 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) |
| oedematous | <medicine> Pertaining to, or of the nature of, oedema; affected with oedema. Source: Websters Dictionary (01 Mar 1998) |

| 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) |
