| West Nile encephalitis virus | Caused by a virus in the family Flaviviridae. Synonym: West Nile virus. (05 Mar 2000) |
| west nile fever | <virology> A tropical disease caused by dengue virus (Arbovirus), that is transmitted by the bite of an infected mosquito of the genus Aedes). Four severity grades of the illness are seen: Grade I (fever and constitutional symptoms) Grade II (grade I plus spontaneous bleeding of skin, gums or gastrointestinal tract) Grade III (grade II plus agitation and circulatory failure) Grade IV (profound shock). Grade I infection is seen most frequently in world travelers, where it is usually self-limited and rarely fatal. The other grades are referred to as dengue haemorrhagic fever and are often fatal. Dengue haemorrhagic fever appears to be an infection by one of the other dengue viruses. Prior immunity to a different dengue virus type appears to be important in the development of the more serious haemorrhagic form. Vaccines are available. Protection from mosquitoes is an important preventive measure. (27 Sep 1997) |
| west nile virus | A species of flavivirus, one of the japanese encephalitis virus group (encephalitis viruses, japanese), which produces encephalitis experimentally when inoculated into some rodents, chicks, birds, or monkeys. In humans, it is seen most frequently in africa, asia, and europe presenting as a silent infection or undifferentiated fever (west nile fever). It is transmitted by culex spp mosquitoes.

| West's syndrome | <syndrome> An encephalopathy in infancy characterised by infantile spasms, arrest of psychomotor development, and hypsarrhythmia. (05 Mar 2000) |
| zone 1, 2, 3, 4 of West | In pulmonary physiology, defines the levels in a vertical lung according to the relationships of alveolar gas pressure, capillary blood pressure, and pulmonary venous pressure. (05 Mar 2000) |
| retrospective studies | Studies used to test aetiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons. (12 Dec 1998) |
| pharmalogical studies | <pharmacology> Studies to assess the potential harmful or other effects of drugs (16 Dec 1997) |
| clinical studies | <pharmacology> Human studies that are designed to measure the safety, efficacy, and appropriate dosage of a new drug or biological. Clinical studies routinely involve the use of a placebo group that is given an inactive substance that looks like the test product. (14 Nov 1997) |
| cohort studies | Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesised to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics. (12 Dec 1998) |
| combination studies | <pharmacology> Studies in which a new drug is evaluated in combination with existing drugs. (09 Jan 1998) |
| multicenter studies | Controlled studies which are planned and carried out by several cooperating institutions to assess certain variables and outcomes in specific patient populations, for example, a multicenter study of congenital anomalies in children. (12 Dec 1998) |
| multivariate studies | The use of statistical techniques for the simultaneous investigations of the influence of several variables. (05 Mar 2000) |
| preclinical studies | <pharmacology> Studies in which a drug is tested on animals and in other non-human test systems. Safety information from such studies are used to support an investigational new drug application. (14 Nov 1997) |
