| idiopathic gout | Acute episodes of crystal-induced synovitis due to abnormality of purine metabolism; lower than normal urinary excretion of urate leading to hyperuricaemia and acute episodes of joint inflammation. Synonym: primary gout. Interval gout, an asymptomatic phase between acute attacks of gout. Latent gout, hyperuricaemia without symptoms of gout. Often used synonymously with interval gout. Synonym: masked gout. (05 Mar 2000) |

| idiopathic hyperlipaemia | Hyperlipoproteinaemia characterised by the presence of large amounts of chylomicrons and triglycerides in the plasma when the patient has a normal diet, and their disappearance on a fat-free diet; low alpha-and beta-lipoproteins on a normal diet, with increase on fat-free diet; decreased plasma postheparin lipolytic activity; and low tissue lipoprotein lipase activity. It is accompanied by bouts of abdominal pain, hepatosplenomegaly, pancreatitis, and eruptive xanthomas; autosomal recessive inheritance. See: familial lipoprotein lipase inhibitor. Synonym: Burger-Grutz syndrome, familial fat-induced hyperlipaemia, familial hyperchylomicronaemia, familial hypertriglyceridemia, idiopathic hyperlipaemia. (05 Mar 2000) |

| idiopathic hypertrophic subaortic stenosis | <cardiology> A congenital heart disease that results in abnormal thickening of the ventricular septum and left ventricular wall. Enlargement of the ventricular septum can result in ventricular outflow obstruction (subaortic stenosis) and eventual cardiomyopathy. (27 Sep 1997) |
| idiopathic hypoparathyroidism | <radiology> Rare condition of unknown cause, round face; short dwarf-like; obese, mental retardation, cataracts, dry scaly skin; atrophy of nails, dental hypoplasia (delayed tooth eruption, impaction of teeth, supernumerary teeth) see: hypoparathyroidism (12 Dec 1998) |
| idiopathic infantilism | Dwarfism generally associated with hypogonadism; may be caused by deficient secretion of anterior pituitary hormones. Synonym: Lorain's disease, proportionate infantilism, universal infantilism. (05 Mar 2000) |
| idiopathic interstitial fibrosis | A progressive inflammatory condition starting with diffuse alveolar damage and resulting in fibrosis and honeycombing over a variable time period; also a common feature of collagen-vascular diseases. Synonym: fibrosing alveolitis, Hamman-Rich syndrome, idiopathic interstitial fibrosis. (05 Mar 2000) |
| idiopathic megacolon | An acquired megacolon, found in children and adults, without distal obstruction or absence of ganglion cells; the muscle of the dilated colon is thin. (05 Mar 2000) |
| idiopathic muscular atrophy | A form of progressive muscular atrophy in which the disease begins in the muscle and not in the spinal centres. Synonym: Erb atrophy, idiopathic muscular atrophy. (05 Mar 2000) |
| idiopathic myelofibrosis | A progressive disease of the bone marrow where neoplastic bone marrow stem cells lodge and grow in multiple sites outside the bone marrow. Typically, there is enlargement of the spleen and a gradual replacement of the bone marrow elements by fibrosis (scarring), progressive anaemia and variable changes in the number of white blood cells and platelets. Diagnosis is by bone marrow biopsy. There is no definitive treatment for this disorder that has been shown to affect life span favorably. (27 Sep 1997) |
