RESUMO
The lack of high-quality health information for accurately estimating burdens of disease in some Aboriginal populations is a challenge for developing effective and relevant public health programmes and for health research. We evaluated data from a health registry system that captured patient consultations, provided by Labrador Grenfell Health (Labrador, Canada). The goal was to evaluate the registry's utility and attributes using modified CDC guidelines for evaluating surveillance systems. Infectious gastrointestinal illness data were used as a reference syndrome to determine various aspects of data collection and quality. Key-informant interviews were conducted to provide information about system utility. The study uncovered limitations in data quality and accessibility, resulting in region-specific recommendations including conversion to an electronic system. More generally, this study emphasized how a systematic and standardized evaluation of health registry systems can help address challenges to obtaining quality health data in often remote areas where many Aboriginal communities are found.

In this study, we report on the indoor radon concentration levels in a number of locations scattered in the Hebron province, Palestine. The measurements were performed during the winter season of the year 1999/2000 using the CR-39 detectors. The radon concentration levels were found to vary from 23 to 580 Bq m(-3). The arithmetic average of the obtained radon concentration levels was found to be 91 Bq m(-3). It was found that most of the radon concentration levels in houses and school rooms are below the low reference levels limits. Most of the high-radon concentration levels were found in unpainted storage rooms.

Isolates of Cephalosporium maydis varied in their pathogenicity to D.C. 67 maize cultivar from highly to weakly pathogenic. Highly pathogenic isolates showed lower activity of polyphenol oxidase, peroxidase, cytochrome oxidase, and beta-glucosidase enzymes and higher activity of catalase and dehydrogenase than weakly pathogenic isolates. Enzymes production by the tested isolates increased as the culture age increased; except in case of catalase enzyme, the reverse action was detected. The role of these enzymes in the virulence of C. maydis is suggested and discussed.
