Berufsbedingte Hauterkrankungen—Paradigma der Sekundärprävention

The dermatologist's procedure was introduced in 1972 by employers' liability insurance funds in the industrial, agricultural and public sectors of Germany's statutory occupational accident insurance as a "procedure for early detection of occupational skin diseases". So far, it is still the most relevant tool for secondary prevention in occupational dermatology in Germany. According to the intention of this procedure, insured persons with a skin disease in which an occupational aetiology is suspected must be offered preventive measures and, if necessary, given appropriate treatment to avoid their losing their jobs. On the initiative of the Central Federation of Industrial Professional Associations (HVBG), a study group was set up in 1999 from among its membership in cooperation with the Working Committee of Occupational and Environmental Dermatology (ABD) and the Professional Organisation of German Dermatologists (BVDD) to improve on the efficiency of the "classic" dermatologist's procedure. The proposed "optimised" dermatologist's procedure is based on the assumption that early detection followed by competent and intensified skin protection and skin care will be successful in retarding or stopping the progression of occupational dermatoses, while later treatment is likely to be less effective. In October 2002, a pilot study started in Northwest Germany to establish by scientific evaluation whether the implementation of secondary protective measures is definitively better when the provisional "optimised" dermatologist's procedure is followed. The study results should allow detailed suggestions for an improved dermatologist's procedure before it is introduced nationwide.

Improving the retention rate of newly graduated nurses.

Newly graduated nurses often finish orientation and then believe they still need more support and mentoring than is available. Retention rates suffer as they think it must be better elsewhere. This article reports a community hospital's implementation of an education-based preceptor program. A convenience sample of 40 new graduates participated in the study. Qualitative and quantitative findings indicate a high level of satisfaction (mean visual analogue scale score 93.7), 29% increase in retention, and 9.5% decrease in vacancy.

Application of an immunosensor for the detection of the β-lactam antibiotic, cephalexin

Public concern surrounding antibiotic contamination in food and food products has made it imperative to develop analytical methods for their detection. Polyclonal antibodies were used in the development of a surface plasmon resonance (SPR)-based inhibition immunoassay for cephalexin. A conjugate consisting of cephalexin-bovine serum albumin (BSA) was immobilized on the dextran gel surface of the sensor chip. Binding/regeneration studies of antibody to immobilized cephalexin were studied and dissociation of the antibody from the immobilized cephalexin was easily achieved with 10 mmol l^-1 NaOH. Forty surface regeneration cycles were carried out and found to be reproducible with only a 7.4% decrease in binding over this number of regenerations. Model inhibition immunoassays for cephalexin were developed in PBS and spiked milk samples with detection ranges of 4.88 to 2,500 ng ml^-1 and 244 to 3,906 pg ml^-1, respectively.     

Ancillary Community Pharmacy Services Provided to Older People in A Largely Rural and Ethnically Diverse Region: A Survey of Consumers in West Texas

Little is known about the quality of pharmacy services provided to the rural elderly population. This exploratory study examines rural/urban and ethnic differences in perceived access to ancillary pharmacy services among elderly people. Two telephone surveys were conducted using directory listings in West Texas to generate a longitudinal sample. Persons aged 65 years and older who were not cognitively impaired were asked to complete the survey. The number of participants in both rounds of the survey was 3,689. Seven ancillary pharmacy services were examined: delivery of medications, medication counseling, written medication information, blood pressure monitoring, blood glucose monitoring, osteoporosis screening, and immunization. The sample was stratified by county of residence (urban, rural, or frontier) and racial/ethnic background. Chi-square tests were performed to detect rural/urban and racial/ethnic differences in access to the seven ancillary services. The association between proficiency in English and access to the services was also examined. Rural residents were more likely than urban residents to report that their pharmacies provide delivery of medications, medication counseling, and immunization services, but they were less likely than their urban counterparts to report that their pharmacies provide blood pressure monitoring. Access to ancillary pharmacy services was reported as poorer by older Hispanic people compared with non-Hispanics. Deficiency in English was significantly related to inequality in reported access to ancillary pharmacy services. It is essential to consider the special needs of rural and Hispanic elderly people to ensure equitable access to ancillary pharmacy services.
