| 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) |
| 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. (12 Dec 1998) |
| lymphatic oedema | Oedema due to stasis in the lymph channels. Synonym: leukophlegmasia. (05 Mar 2000) |
| blood pressure, high | High blood pressure (hypertension) is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg. High blood pressure is also called the silent killer. Chronically high blood pressure can cause blood vessel changes in the back of the eye (retina), thickening of the heart muscle, kidney failure, and brain damage. No specific cause for high blood pressure is found in 95% of patients. High blood pressure is treated with salt restriction, regular aerobic exercise, and medications. (12 Dec 1998) |
| blood sugar, high | Elevated levels of blood glucose (hyperglycaemia) can be found in a number of conditions. The hyperglycaemia leads to spillage of glucose into the urine, hence the term sweet urine. (Diabetes mellitus means sweet urine. ) (12 Dec 1998) |
| cardiac output, high | A state of elevated cardiac output. Conditions that lower peripheral vascular resistance, such as anaemia, arteriovenous fistulas, thyrotoxicosis, and pregnancy, are among the most important factors augmenting the venous return and therefore elevating cardiac output. Increased cardiac output also occurs in muscular exercise, fever, and severe anoxia. (12 Dec 1998) |
| radiotherapy, high-energy | Radiotherapy using high-energy (megavolt or higher) ionizing radiation. Types of radiation include gamma rays, produced by a radioisotope within a teletherapy unit; X-rays, electrons, protons, alpha particles (helium ions) and heavy charged ions, produced by particle acceleration; and neutrons and pi-mesons (pions), produced as secondary particles following bombardment of a target with a primary particle.
