摘要:

We evaluated cancer mortality patterns among hairdressers and barbers, according to occupation, coded on 7.2 million death certificates in 24 states from 1984 to 1995. Of the 38,721 deaths among white and black hairdressers and barbers of both sexes, 9495 were from all malignant neoplasms. Mortality odds ratios were significantly elevated for all malignant neoplasms, lung cancer, and all lymphatic and hemopoietic cancers among black and white female hairdressers. White female hairdressers had significant excess mortality from cancers of the stomach, colon, pancreas, breast, and bladder and from non-Hodgkin’s lymphoma and lymphoid leukemia; mortality from these cancers was also elevated among black female hairdressers. White male hairdressers had significantly elevated mortality from non-melanoma skin cancer and non-Hodgkin’s lymphoma. Mortality from all malignant neoplasms, although significantly elevated among both white and black female hairdressers, was significantly below the null for white male hairdressers. Black and white male barbers had significantly elevated mortality from stomach and pharyngeal cancer, respectively. A significant deficit in mortality from all neoplasms and cancers of the pancreas, lung, and prostate was noted for white male barbers. This large study of cancer mortality among hairdressers and barbers showed some differences in mortality patterns by gender and race. Further studies are required to determine if specific occupational exposures may explain some of the elevated cancer rates.

摘要:

The foci of this brief report are to (1) describe the prevalence of chemical sensitivity (CS) and chronic fatigue (CF) symptomatology and of presumptive multiple CS and CF syndrome diagnoses, and (2) explore the potential overlap between one purported case definition (ie, chronic multi-symptom illness) and these unexplained symptom syndromes in a well-characterized group of Gulf War veterans. The number of subjects with CS and CF symptomatology and presumptive multiple CS and CF syndrome diagnoses was higher in the Gulf War–deployed group compared with a group deployed to Germany during the Gulf War. However, the percent differences were not significant when comparing the presumptive diagnoses of multiple CS and CF syndrome. The characteristic differences between the groups and the overlap with chronic multi-symptom illness are also discussed.

摘要:

Data on the use of various therapeutic interventions among working populations at risk for musculoskeletal disorders are rare, despite the need for such information in assessing adherence to best practices. Using the results of a cross-sectional survey of newspaper workers who reported neck and upper limb pain or discomfort (n= 309), we describe the prevalence of a wide range of clinical and workplace interventions. Information/education, exercises, and physical treatments were the most common interventions, and work changes were less prevalent. Those with more frequent, longer-duration, and/or more severe symptoms more commonly reported visits to physiotherapists and health practitioners at work and use of physical treatments, medications, and devices. The multiplicity of interventions used pose evaluation challenges for occupational health practitioners and researchers.

摘要:

Modified-work programs are designed to facilitate the return to work for employees with a work-related injury. Although extensive published literature exists that describes and evaluates “ideal” programs, to date there is a paucity of data describing practice. To address this pertinent issue, we administered a survey to a large sample of 1833 workers with soft-tissue injuries in Ontario, Canada, and asked them detailed questions about modified work and employer contact. Our results reveal that most workers (66%) were contacted by someone from their workplace to check on how they were doing. However, only a minority (36%) were offered arrangements by their employer to help them return to work after developing a work-related soft-tissue injury. Most arrangements that were offered to injured workers consisted of such temporary modifications as reduced hours (24%), flexible work hours (25%), or a lighter job (57%) rather than more permanent changes to the way that work is conducted, such as changes to the work layout or equipment (8%). Merely being contacted by the workplace to check on how the worker was doing was not associated with reduced compensation benefit duration. Workplace offers of arrangements to help the worker return to work were associated with reduced compensation benefit duration but were not statistically associated with workers’ pain grade.

摘要:

Traditionally, inadequate training has been considered the major barrier to recognition of occupational disease. A survey of 136 practitioners was conducted to determine which barriers were actually considered most relevant. The sample included three subgroups: primary care, occupational medicine–oriented, and Mexican. Four aggregate indices were derived: Knowledge, Time, Unpleasant aspects, and Importance. Inadequate Time was as important as inadequate Knowledge, whereas perceived lack of Importance and Unpleasant aspects were less relevant. Patterns among the subgroups were generally comparable. This study implies that training more occupational medicine specialists in increasing recognition is not sufficient unless specific strategies to overcome time constraints are also implemented. For example, emphasizing a “complete occupational history” may be counterproductive. Limiting histories to selected patients; use of focused, brief histories; and, perhaps, computer-based methods are needed.

摘要:

A back school was established in 1992 at the University Hospital of Lille (France) for employees with low back pain. We report its medical and socioeconomic benefits with a mean time to follow-up of 4 years. Our retrospective study included 108 health care workers and provides objective data (absenteeism, use of health care) and subjective information (progression of pain and disorder, social and professional impact) before training and a mean of 4 years after training. We found that 92% of the participants were satisfied with the training and that back pain had regressed or resolved for 55% of them. Both the frequency and duration of pain had decreased significantly. Seventy percent continue to apply the advice they received in their everyday life. Dealing with the problems specific to professional activities contributed to reduce the strain experienced on the job by the health care workers and improved their satisfaction at work. Global absenteeism was reduced by 57.8%, whereas it was reduced by 33% for back pain alone 4 years after implementing this program. Our study provides evidence of the positive impact of this type of training on the way back pain is perceived and on everyday life. The assessment of the cost/efficiency ratio completes the list of durable benefits reported here.

摘要:

Tremor is being increasingly evaluated by quantitative computer-based systems to differentiate its causes. In this study, a group of mercury-exposed workers were assessed to determine whether tremor characteristics differed by exposure level. Workers were classified into two groups: those with an average urine mercury concentration below the American Conference of Government Industrial Hygienist Biological Exposure Index of 35 &mgr;g/g creatinine, and those with an average urine mercury concentration above the Biological Exposure Index. Tremor characteristics (including intensity, harmonic index, center frequency, standard deviation of the center frequency, and tremor index) were measured and recorded with a computer-based tremor system. Sixteen of 17 workers who were potentially exposed to mercury participated in the study. Three workers had a mean urine mercury concentration of 27.0 &mgr;g/g-creatinine and were assigned to the low-exposure group, and 13 workers had a mean urine mercury concentration of 200.2 &mgr;g/g-creatinine and were assigned to the high-exposure group. There was a statistically significant difference in the tremor index (which compiles five individual tremor parameters into a single value) between the two groups (P= 0.04; Wilcoxon’s rank sum test). Other tremor characteristics did not differ significantly between the groups. Tremor index may be more useful than measures of individual tremor parameters in differentiating normal from subclinical pathological tremors among groups of workers with chronic mercury exposure.
