| hydraemic oedema | An obsolete term for oedema occurring in states marked by pronounced hydraemia. (05 Mar 2000) |
|---|---|
| solid oedema | Infiltration of the subcutaneous tissues by mucoid material, as in myxoedema. (05 Mar 2000) |
| nephrotic oedema | Oedema resulting from renal dysfunction. (05 Mar 2000) |
| noninflammatory oedema | <clinical sign> Oedema due to mechanical or other causes, not marked by inflammation or congestion. (05 Mar 2000) |
| nonpitting oedema | Swelling of subcutaneous tissues which cannot be indented by compression easily. Usually due to metabolic abnormality, such as increased glycosaminoglycan content, like that which occurs in Graves' disease (pretibial myxoedema) or in early phase of scleroderma. Synonym: brawny oedema. (05 Mar 2000) |
| nutritional oedema | A form of swelling caused by insufficient protein intake resulting in hypoproteinaemia and low plasma oncotic pressure. (05 Mar 2000) |
| dependent oedema | A clinically detectable increase in extracellular fluid volume localised in a dependent area, as of a limb, characterised by swelling or pitting. (05 Mar 2000) |
| Quincke's oedema | A vascular reaction involving the deep dermis or subcutaneous or submucal tissues, representing localised oedema caused by dilatation and increased permeability of the capillaries and characterised by development of giant wheals. (18 Nov 1997) |
| infantile acute haemorrhagic oedema of the skin | A generally benign form of cutaneous vasculitis, characterised by ecchymotic purpura, often in a cockade pattern, and inflammatory oedema in infants. (05 Mar 2000) |
| inflammatory oedema | A swelling due to effusion of fluid in the soft parts surrounding a focus of inflammation. (05 Mar 2000) |
| 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 glottidis | Oedema of the larynx. (05 Mar 2000) |
| 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) |
