Changes in the attitudes of GPs to health screening of patients with learning disabilities

GP's appear reluctant to undertake health screening for people with learning disabilities. This article describes a specialist health screening service delivered mainly by community learning disability nurses to nearly 600 children and adults. Prior to the service being established, 141 GPs within a defined area were surveyed and 51% responded. Although a majority thought the service would be helpful, three-quarters felt it was better provided within the context of specialist services. After screening, 54% of the sample (318 persons) were referred to their GP for further assessment and treatment, nearly all for physoical health needs. A second study investigated the attitudes of 91 GPs who had patients refrrered. Those (45) who reported dealing with a referral were more favourably disposed to undertaking health screening within their practice, whereas those (23) who had been uninvolved continued to opt for specialist provision. Options for encouraging more GPs' to offer preventive health care to theisclient group are discussed, including medical training, extra consulting time and linking community learning disbaility nurses with GP practices.

Development of an ELISA screening test for nitroimidazoles in egg and chicken muscle

An antibody was generated that can bind metronidazole (MNZ), a nitroimidazole drug used in veterinary medicine to treat poultry for coccidiosis and histomoniasis. A direct competitive enzyme-linked immunosorbent assay (cELISA) is described. It was used to characterise binding of this antibody to a number of nitroimidazole drugs. It displayed cross-reactivity with dimetridazole (DMZ), ronidazole (RNZ), hydroxydimetridazole (DMZOH), and ipronidazole (IPZ).

Screening for the coccidiostats halofuginone and nicarbazin in egg and chicken muscle: development of an ELISA

Nicarbazin and halofuginone have been widely used as coccidiostats for the prevention and treatment of coccidiosis in poultry. It has been shown that accidental cross-contamination of feed can lead to residues of these compounds in eggs and/or muscle. This paper describes a direct competitive assay for detecting halofuginone and nicarbazin, developed as qualitative screening assay. In an optimized competitive ELISA, antibodies showed 50% binding inhibition at approximately 0.08 ng ml(-1) for halofuginone and 2.5 ng ml(-1) for dinitrocarbanilide (marker residue for nicarbazin). Extraction from the matrix was carried out with acetonitrile followed by a wash with hexane. The assay's detection capability (CCbeta) for halofuginone was
