摘要:

Reviewing Workers' Compensation records for back injury from a large university hospital for a 2-year period, we found a yearly incidence of lost work time back injury among nurses of 2.0% per year, exceeded only by physical plant staff, who had a rate of 3.5%. Nurses' aides had an injury rate 3.3-fold higher than registered nurses and licensed practical nurses and higher than any other occupational group. We compared 100 cases of nurses with back injury in the previous 2 years with 197 noninjured control subjects using a mailed 40-item questionnaire. Multivariate logistic modelling showed that prior nonback injury and performing combined lifting activities were statistically significant risk factors for back injury, and being overweight approached significance, after adjusting for the effects of age, gender, and each of the evaluated risk factors.

摘要:

Colorectal cancer affects more than 157,000 Americans annually. Occupational risk from exposure to asbestos dust has been implicated, leading us to explore further the possible association between colorectal cancer and asbestos. Two hundred sixty-one cases of colon and rectal cancer and 183 control cases were identified within a large, population-based case-control study conducted in southeast Michigan. Employment in occupations historically known to involve heavy exposure to asbestos was used as a surrogate for asbestos exposure. Cancers of the colon showed reduced odds ratios. Our findings differ substantially from those of the previous studies showing elevated risk. Further study is needed to address the same question, with specified asbestos exposure assessment and control for potentially significant confounders such as physical activity and diet.

摘要:

Loss of vibration sensibility has been suggested as an early indicator of peripheral compression neuropathy, including carpal tunnel syndrome. Although vibration sensibility has been used frequently to evaluate carpal tunnel syndrome, the day-to-day reliability of vibration measurements in an industrial population measured at the workplace has not been assessed. Vibration sensibility testing was performed at the university ergonomics laboratory on 50 volunteers (100 hands) and at a newspaper company on 50 workers (100 hands). Vibration perception and disappearance thresholds were measured on two occasions separated by 3 to 5 days. Student's t tests indicated no significant differences between the first and second tests or between the two groups. Pearson product-moment correlations for test-retest reliability were lower in the industry group but were relatively high despite the less than optimal testing conditions. Our findings suggest that vibration sensibility measurements are reliable from day to day not only in the laboratory but also in the workplace.
