| type I diabetes | A chronic condition in which the pancreas makes little or no insulin because the beta cells have been destroyed. The body is then not able to use the glucose (blood sugar) for energy. IDDM usually comes on abruptly, although the damage to the beta cells may begin much earlier. The signs of IDDM are a great thirst, hunger, a need to urinate often, and loss of weight. To treat the disease, the person must inject insulin, follow a diet plan, exercise daily, and test blood glucose several times a day. IDDM usually occurs in children and adults who are under age 30. This type of diabetes used to be known as juvenile diabetes, juvenile-onset diabetes, and ketosis-prone diabetes. (09 Oct 1997) |

| type I diabetes mellitus | <endocrinology> A severe metabolic disorder which has an abrupt onset before the age of twenty. In it, an insulin deficiency prevents the body from using carbohydrates properly and forces it to rely mainly on protein metabolism. Treatment of the disease includes strict dietary regulation and mandatory insulin injections. (09 Oct 1997) |
| type I dip | Early deceleration of the foetal heart rate at the height of uterine contraction, as displayed on a foetal monitor graph. (05 Mar 2000) |
| type i error | The statistical error (said to be of the first kind or alpha error) made in testing an hypothesis when it is concluded that a treatment or intervention is effective when it really is not. Sometimes referred to as a false positive. (12 Dec 1998) |
| type I familial hyperlipoproteinaemia | 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) |
| type IH mucopolysaccharidosis | <syndrome> Mucopolysaccharidosis in which there is a deficiency of alpha-l-iduronidase, an accumulation of an abnormal intracellular material, and excretion of dermatan sulfate and heparan sulfate in the urine; with severe abnormality in development of skeletal cartilage and bone, with dwarfism, kyphosis, deformed limbs, limitation of joint motion, spadelike hand, corneal clouding, hepatosplenomegaly, mental retardation, and gargoyle-like facies; autosomal recessive inheritance. See: mucolipidosis. Synonym: dysostosis multiplex, Hurler's disease, lipochondrodystrophy, Pfaundler-Hurler syndrome, type IH mucopolysaccharidosis. (05 Mar 2000) |
| type I H/S mucopolysaccharidosis | <syndrome> Although clinically distinct diseases, fibroblasts from patients with Hurler syndrome and with Scheie syndrome do not cross complement in culture, suggesting that the enzyme defect is the same. (18 Nov 1997) |
| type I hyperlipoproteinaemia | <biochemistry> An rare inherited disorder where there is a deficiency of an enzyme (lipoprotein lipase) which breaks down fat molecules, causing the accumulation of fats or lipoproteins in the blood. Symptoms in infancy include abdominal pain (appears as if its colic), failure to thrive and skin lesions (xanthomas). Origin: Gr. Haima = blood (27 Sep 1997) |
| type II acrocephalosyndactyly | type II acrocephalosyndactyly |
| type II cells | Cuboidal cell's connected with the squamous pulmonary alveolar cell's and having in their cytoplasm lamellated bodies (cytosomes) that represent the source of the surfactant that coats the alveoli. Synonym: granular pneumonocytes, type II cells. (05 Mar 2000) |
| type II collagen | Collagen unique to cartilage, nucleus pulposis, notochord, and vitreous body; it forms as thin highly glycosylated fibrils. (05 Mar 2000) |
| type II diabetes | <disease> An often mild form of diabetes mellitus of gradual onset, usually in obese individuals over age 35; absolute plasma insulin levels are normal to high, but relatively low in relation to plasma glucose levels; ketoacidosis is rare, but hyperosmolar coma can occur; responds well to dietary regulation and/or oral hypoglycaemic agents, but diabetic complications and degenerative changes can develop. (05 Mar 2000) |
| type II dip | Late deceleration of the foetal heart rate, 30 seconds or more after the height of uterine contraction, as displayed on a foetal monitor graph. (05 Mar 2000) |
| type II error | The statistical error (said to be of the second kind or beta error) made in testing an hypothesis when it is concluded that a treatment or intervention is not effective when it really is. Sometimes referred to as a false negative. (12 Dec 1998) |
| type II familial hyperlipoproteinaemia | Hyperlipoproteinaemia characterised by increased plasma levels of beta-lipoproteins, cholesterol, and phospholipids, but normal triglycerides; heterozygotes have mild lipid changes and are susceptible to atherosclerosis in middle age, but homozygotes have severe changes often with generalised xanthomatosis and xanthelasma, and frank clinical atherosclerosis as young adults. The primary defect is a deficiency of apoprotein of VLDL, and the disorder is divided into two classes: 1) type IIA, which has elevated LDL due to a deficiency of the receptor or a modified apolipoprotein B-100; 2) type IIB, which has elevated LDL and triglycerides; autosomal dominant inheritance. Synonym: familial hyperbetalipoproteinaemia, familial hypercholesteraemic xanthomatosis, familial hypercholesterolaemia. (05 Mar 2000) |
