|---|---|
| multiple carboxylase deficiency | Abnormalities in carbohydrate and branched-chain amino acid catabolism that are responsive to biotin therapy. It may be due to deficiency of propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, biotinidase, or propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and pyruvate carboxylase. (12 Dec 1998) |
| multiple chemical sensitivity | An acquired disorder characterised by recurrent symptoms, referable to multiple organ systems, occurring in response to demonstrable exposure to many chemically unrelated compounds at doses far below those established in the general population to cause harmful effects. No single widely accepted test of physiologic function can be shown to correlate with symptoms. (cullen mr. The worker with multiple chemical sensitivities: an overview. Occup med 1987;2(4):655-61) (12 Dec 1998) |
| multiple cloning site | Region of a phage or plasmid vector that has been engineered to contain a series of restriction sites that are usually unique within the entire vector. This makes it particularly easy to insert or excise (subclone) DNA fragments. (18 Nov 1997) |
| multiple drug resistant tuberculosis | A strain of TB that does not respond to two or more standard anti-TB drugs. MDR-TB usually occurs when treatment is interrupted thus allowing mutations in the organism to occur that confer drug resistance. (09 Oct 1997) |
| multiple ego states | Various psychological organizational state's reflecting different personas or life experiences. (05 Mar 2000) |
| multiple embolism | Embolism caused by the arrest of a number of small emboli. (05 Mar 2000) |
| multiple endocrine adenomatosis | The presence of functioning tumours in more than one endocrine gland, commonly the pancreatic islets and parathyroid glands, which may be associated with Zollinger-Ellison syndrome; dominant inheritance. Synonym: multiple endocrine adenomatosis. (05 Mar 2000) |
| multiple endocrine deficiency syndrome | <syndrome> Acquired deficiency of the function of several endocrine glands, usually on an auto-immune basis. Synonym: multiple glandular deficiency syndrome. (05 Mar 2000) |
| multiple endocrine neoplasia | (type I) This is a hereditary disorder in which two or more of the following glands: parathyroid, pancreas, pituitary, adrenals or thyroid develop hyperplasia or a tumour. (type II) This is a hereditary disorder in which two or more of the following glands: thyroid, adrenal or parathyroid, develop overgrowth (hyperplasia) or malignant cells (cancer). The underlying cause is genetic and a positive family history for this illness is a risk factor. Incidence: approximately 3 in 100,000 people in the general population. Origin: Gr. Plassein = to form (27 Sep 1997) |
| multiple endocrine neoplasia 1 | <radiology> Multiple endrocrine neoplasia syndrome three P's. Pituitary adenoma, 65% can develop Cushing's, acromegaly, prolactinoma, parathyroid hyperplasia / adenoma, 88% can develop hyper-PTH pancreatic isleT-cell tumour, gastrinoma (Z-E) most common, 50% of Z-E can develop MEN-1, inconstant features: bronchial/intestinal carcinoid, thyroid adenoma, adrenal cortical tumour, lipoma, thymoma tissue expression Primary hyperparathyroidism (90%), Gastrinoma (30%), Prolactinoma (15%), Other (10%). Synonym: Wermer syndrome (12 Dec 1998) |
| multiple endocrine neoplasia 2 | <radiology> Multiple endocrine neoplasia syndrome, medullary thyroid carcinoma, usually multifocal; metastasis to local nodes, lung, liver, usually calcify in liver, pheochromocytoma, almost always bilateral, parathyroid hyperplasia, may be secondary to calcitonin secreted by medullary thyroid carcinoma inconstant feature: adrenal cortical hyperplasia Synonym: Sipple syndrome (12 Dec 1998) |
| multiple endocrine neoplasia 3 | <radiology> Multiple endocrine neoplasia syndrome (type 2B, type 3), medullary thyroid carcinoma, pheochromocytoma, marfanoid habitus (Cf: Marfan syndrome), mucosal neuromas, neurofibromas, ganglioneuromatosis coli More info: MEN syndrome 2B Synonym: Schimke, marfanoid syndrome (12 Dec 1998) |
| multiple endocrine neoplasia type 1 | A rare syndrome characterised by hyperplasia and/or neoplasms of the pituitary, parathyroid glands, and pancreatic islets. Hyperparathyroidism occurs in 90% of the cases and is usually the first manifestation of the syndrome. The most frequent pancreatic manifestation is gastrinoma typically leading to zollinger-ellison syndrome. The appearance of this condition has been limited to the loss of allelic heterozygosity at the 11q13 locus on the long arm of chromosome 11. Patients overall exhibit long survival times. Chemotherapy is rare and surgical management is generally dependent on the genetic expression in individual patients. (12 Dec 1998) |
