| information science | The field of knowledge, theory, and technology dealing with the collection of facts and figures, and the processes and methods involved in their manipulation, storage, dissemination, publication, and retrieval. It includes the fields of communication, publishing, library science and informatics. (12 Dec 1998) |
|---|---|
| information services | Organised services to provide information on any questions an individual might have using databases and other sources. (12 Dec 1998) |
| information system | Combination of vital and health statistical data from multiple sources, used to derive information and make decisions about the health needs, health resources, costs, use, and outcome of health care. (05 Mar 2000) |
| information systems | Integrated set of files, procedures, and equipment for the storage, manipulation, and retrieval of information. (12 Dec 1998) |
| information theory | An interdisciplinary study dealing with the transmission of messages or signals, or the communication of information. Information theory does not directly deal with meaning or content, but with physical representations that have meaning or content. It overlaps considerably with communication theory and cybernetics. (12 Dec 1998) |
| integrated advanced information management systems | A concept, developed in 1983 under the aegis of and supported by the national library of medicine under the name of integrated academic information management systems, to provide professionals in academic health sciences centres and health sciences institutions with convenient access to an integrated and comprehensive network of knowledge. It addresses a wide cross-section of users from administrators and faculty to students and clinicians and has applications to planning, clinical and managerial decision-making, teaching, and research. It provides access to various types of clinical, management, educational, etc., databases, as well as to research and bibliographic databases. In august 1992 the name was changed from integrated academic information management systems to integrated advanced information management systems to reflect use beyond the academic milieu. (12 Dec 1998) |
| operating room information systems | Information systems, usually computer-assisted, designed to store, manipulate, and retrieve information for planning, organizing, directing, and controlling administrative activities associated with the provision and utilization of operating room services and facilities. (12 Dec 1998) |
| brancher glycogen storage disease | Type of glycogen storage disease, due to deficiency of amylo-1,4-1,6-transglucosidase (brancher enzyme). Synonym: brancher deficiency glycogenosis, debrancher deficiency. (05 Mar 2000) |
| glycogen storage disease | <hepatology> A group of inherited metabolic disorders involving the enzymes responsible for the synthesis and degradation of glycogen. In some patients, prominent liver involvement is presented. In others, more generalised storage of glycogen occurs, sometimes with prominent cardiac involvement. Synonym: glycogenosis (12 Sep 2002) |
| glycogen storage disease type I | <disease> An autosomal recessive disease in which gene expression of glucose-6-phosphatase is absent, resulting in hypoglycaemia due to lack of glucose production. Accumulation of glycogen in liver and kidney leads to organomegaly, particularly massive hepatomegaly. Increased concentrations of lactic acid and hyperlipidemia appear in the plasma. Clinical gout often appears in early childhood. Inheritance: autosomal recessive. (12 Dec 1998) |
| glycogen storage disease type II | <disease> Glycogenosis due to alpha-1,4-glucosidase (acid maltase) deficiency. It affects muscle, heart, and other organs. (12 Dec 1998) |
| glycogen storage disease type III | <disease> An autosomal recessive metabolic disorder due to deficient expression of amylo-1,6-glucosidase (one part of the glycogen debranching enzyme system). The clinical course of the disease is similar to that of glycogen storage disease type I, but milder. Massive hepatomegaly, which is present in young children, diminishes and occasionally disappears with age. Levels of glycogen with short outer branches are elevated in muscle, liver, and erythrocytes. Six subgroups have been identified, with subgroups type IIIa and type IIIb being the most prevalent. Inheritance: autosomal recessive (12 Dec 1998) |
| glycogen storage disease type IV | <disease> An autosomal recessive metabolic disorder due to a deficiency in expression of branching enzyme (alpha-1,4-glucan-6-alpha-glucosyltransferase), resulting in an accumulation of abnormal glycogen with long outer branches. Clinical features are muscle hypotonia and cirrhosis. Death from liver disease usually occurs before age 2. Inheritance: autosomal recessive (12 Dec 1998) |
| glycogen storage disease type V | <disease> Glycogenosis due to muscle phosphorylase deficiency. Characterised by painful cramps following sustained exercise. Inheritance: autosomal recessive (12 Dec 1998) |
| glycogen storage disease type VI | <disease> A hepatic glycogen storage disease in which there is an apparent deficiency of hepatic phosphorylase activity. However, studies have not been able to distinguish between phosphorylase deficiency and phosphorylase kinase deficiency in patients with hepatic glycogenosis. (12 Dec 1998) |
