Prevalence of tuberculosis infection among homeless young people in central and eastern Sydney.

OBJECTIVE: To determine the prevalence of tuberculosis (TB) infection among homeless young people (aged 12-25 years) in central and eastern Sydney. METHODOLOGY: A cross-sectional survey was conducted in 16 youth refuges and four drop-in centres in Central and Eastern Sydney Health Areas and at the Cellblock Youth Health Centre, Glebe and the Kirketon Road Centre, Darlinghurst, New South Wales (NSW). Participants completed a questionnaire and underwent Mantoux testing. RESULTS: One hundred and forty-one young people completed questionnaires and 139 received a Mantoux test; 112 (80. 6%) had their Mantoux read and 10 (8.9%) were Mantoux positive (95% confidence interval 3.6-14.2). None of the risk factors examined were found to be associated with increased risk for TB infection. CONCLUSIONS: In this sample of homeless young people in central and eastern Sydney, the Mantoux positivity rate appears to be higher than the general population in NSW, but they would not currently be considered a high-risk group for TB infection.

A citywide survey of vancomycin-resistant Enterococcus--New York City, 1993.

Vancomycin-resistant Enterococcus (VRE) has become an increasingly important nosocomial pathogen. Questionnaires were sent to all New York City (NYC)-licensed laboratories to ask about testing procedures used, number of isolates identified, species identified, and vancomycin susceptibility for enterococcal isolates in 1993. Of 127 laboratories, 118 (93%) responded. Fifty-three (45%) of the 118 laboratories reported both the number of enterococcal isolates tested and the number of VRE isolates identified during 1993; 15 (28%) of the 53 laboratories did not isolate VRE, and the remaining 38 laboratories identified 3,822 (8.1%) VRE isolates. VRE was first identified by a NYC-licensed (commercial) laboratory in 1988. Among NYC hospital laboratories, 65 (97%) of 67 identified at least one VRE isolate during 1989-1993. This survey demonstrates that there has been a marked increase in the number of VRE isolates identified in NYC laboratories.

Early sibling attachment.

A sample of 30 predominantly three- and four-year-old siblings were videotaped during their first meeting with a new sibling at the time of the mother's discharge from the hospital. The first five minutes of interaction were divided into 20, 15-second intervals, and each interval was coded for the presence or absence of 28 behaviors believed to be related to the early attachment process. The exploration behaviors of siblings showed considerable uniformity. The sibling's age, sex, or participation in sibling preparation classes produced no marked differences in behavior. Recommendations are made for further research.

Potential of machine-vision light microscopy in toxicologic pathology.

Major developments in machine-vision light microscopy and in reagent chemistry have led to a renaissance and revolution in the use of the light microscope in biology, biotechnology, and medicine. The potential use of this technology in the field of toxicologic pathology is discussed. It is suggested that a combination of investigating living cells and tissues and fixed samples using the new technologies will lead to understanding mechanisms of toxicity. Examples of the use of the methods in basic cell biology and medicine are presented.
