| CCH | C-cell hyperplasia; chronic chloride hemagglutination; chronic cholestatic hepatitis |
| CLAH | congenital lipoid adrenal hyperplasia |
| thymus hyperplasia | Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis. (12 Dec 1998) |

| endometrial hyperplasia | <gynaecology, pathology> Thickening of the endometrial lining due to an overgrowth of mucosal cells. Symptoms often include irregular vaginal bleeding, heavy or prolonged menstrual cycles and post-menopausal bleeding in older women. Origin: Gr. Plassein = to form (07 Apr 1998) |
| transmissible murine colonic hyperplasia | A disease of young mice caused by the bacterium Citrobacter freundii and characterised by diarrhoea and mucosal hyperplasia of the descending colon. (05 Mar 2000) |
| fibromuscular hyperplasia | Thickening of arterial media by fibrosis and muscular hyperplasia, usually involving the renal arteries and causing multifocal stenosis and hypertension; a variety of fibromuscular dysplasia. (05 Mar 2000) |
| focal epithelial hyperplasia | Hyperplasia of the mucous membrane of the lips, tongue, and less commonly, the buccal mucosa, floor of the mouth, and palate, presenting soft, painless, round to oval sessile papules about 1 to 4 mm in diameter. The condition usually occurs in children and young adults and has familial predilection, lasting for several months, sometimes years, before running its course. A viral aetiology is suspected, the isolated organism being usually the human papilloma virus. (12 Dec 1998) |
| 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) |
| bar joint denture | A complete denture that is supported by both soft tissue and natural teeth that have been altered so as to permit the denture to fit over them. The altered teeth may have been fitted with short or long copings, locking devices, or connecting bars. Synonym: bar joint denture, hybrid prosthesis, overdenture, telescopic denture. (05 Mar 2000) |
| partial denture | A dental prosthesis which restores one or more, but less than all, of the natural teeth and/or associated parts and which is supported by the teeth and/or the mucosa; it may be removable or fixed. Synonym: bridgework. Distal extension, a removable partial denture that is retained by natural teeth at one end of the denture base segments only, and in which a portion of the functional load is carried by the residual ridge. (05 Mar 2000) |
| partial denture impression | An impression or negative copy of all or a part of the partially edentulous dental arch or area, made for the purpose of designing or constructing a partial denture. (05 Mar 2000) |
| partial denture retention | The fixation of a removable partial denture by the use of clasps, indirect retainers, or precision attachments. (05 Mar 2000) |
| removable partial denture | A partial denture which supplies teeth and associated structures on a partially edentulous jaw, and which can be readily removed from the mouth. Synonym: removable bridge. (05 Mar 2000) |
| wax model denture | A setup of artificial teeth so fabricated that it may be placed in the patient's mouth to verify esthetics, for the making of records, or for any other operation deemed necessary before final completion of the denture. Synonym: wax model denture. (05 Mar 2000) |
| complete denture | A dental prosthesis which is a substitute for the lost natural dentition and associated structures of the maxillae or mandible. Synonym: full denture. (05 Mar 2000) |
| complete denture impression | An impression of an edentulous arch made for the purpose of constructing a complete denture, a negative registration of the entire denture-bearing, stabilizing area of either the maxillae or mandible, a negative registration of the entire denture foundation and border seal areas present in the edentulous mouth. (05 Mar 2000) |
| provisional denture | A dental prosthesis to be used for a short interval of time for reasons of esthetics, mastication, occlusal support, or convenience, or to condition the patient to accept an artificial substitute for missing natural teeth until more definite prosthetic dental treatment can be provided. Synonym: provisional denture, temporary denture. (05 Mar 2000) |
