|---|---|
| nodular transformation of the liver | A rare condition in which nodules of hyperplastic hepatocytes develop without fibrosis or general loss of lobular architecture. Synonym: nodular regenerative hyperplasia. (05 Mar 2000) |
| nodular tuberculid | A type of panniculitis characterised histologically by the presence of granulomas, vasculitis, and necrosis. It is traditionally considered to be the tuberculous counterpart of nodular vasculitis, but is now known to occur without tuberculous precedent. It is seen most commonly in adolescent and menopausal women, is initiated or exacerbated by cold weather, and typically presents as one or more recurrent erythrocyanotic nodules or plaques on the calves. The nodules may progress to form indurations, ulcerations, and scars. (12 Dec 1998) |
| nodular vasculitis | Chronic or recurrent nodular lesions of subcutaneous tissue, especially of the legs of older women, with lobular panniculitis, granulomatous inflammation with multinucleated giant cells, focal necrosis, and obliterative inflammation of the small blood vessels, resembling erythema induratum but without evidence of associated tuberculosis. (05 Mar 2000) |
| focal nodular hyperplasia | <radiology> Focal nodules of normal hepatocytes, Kuppfer cells and bile ducts, F more than M, rare, benign, multiple in 20%, haemorrhage (most common complication) in only 2-3% (unlike hepatic adenoma), stellate fibrous septae (stellate scar), NM: normal or increased uptake on HIDA and sulfur colloid (12 Dec 1998) |
| localised nodular tenosynovitis | A nodule, possibly inflammatory in nature, arising commonly from the flexor sheath of the fingers and thumb; composed of fibrous tissue, lipid-and haemosiderin-containing macrophages, and multinucleated giant cells. Synonym: localised nodular tenosynovitis. (05 Mar 2000) |
| megacolon, toxic | Acute dilatation of the colon associated with amebic or ulcerative colitis. The dilatation may precede perforation of the colon. (12 Dec 1998) |
| goiter, diffuse toxic | Graves' disease, the most common cause of hyperthroidism, too much thyroid hormone. (12 Dec 1998) |
| goiter, toxic multinodular | Condition in which the thyroid gland contains multiple lumps (nodules) that are overactive and produce excess thyroid hormones. This condition is also known as Parry's disease or Plummer's disease. (12 Dec 1998) |
| plants, toxic | Plants or plant parts which are harmful to man or other animals. (12 Dec 1998) |
| hepatitis, toxic | Acute hepatitis caused by true hepatotoxins such as amanita phaloides toxin, carbon tetrachloride, yellow phosphorus, and a variety of drugs. (12 Dec 1998) |
| shock, toxic | See Syndrome, toxic shock. (12 Dec 1998) |
| syndrome, toxic shock | A grave condition occurring predominantly in menstruating women using tampons, toxic shock is characterised by a highly toxic state (with sudden high fever, vomiting, diarrhoea, muscle aching) followed by low blood pressure (hypotension) which can lead to shock (and death). There may be a rash resembling sunburn with peeling of skin. The channing laboratory in boston under dr. Edw. Kass discovered that toxic shock was due to a toxin produced by staph (staphylococcus) aureus bacteria growing under conditions with little or no oxygen. The syndrome occurs rarely in women not using tampons and in men. (12 Dec 1998) |
| drugs toxic to lung | <radiology> Bleomycin, methotrexate, cytoxan, amiodarone (12 Dec 1998) |
| toxic | Pertaining to, due to or of the nature of a poison or toxin, manifesting the symptoms of severe infection. (18 Nov 1997) |
