摘要:

Back pain is the commonest cause of absence among coal miners. However, the degree of morbidity is variable. To determine whether the susceptible individual can be identified, ultrasound was used to measure the spinal canal diameters of 204 miners. The results show that those men with the longest histories and the longest times off work and those who had to leave the coalface or who left the industry – i.e., those with the greatest morbidity – had significantly narrower canals. Ultrasonic measurement of the spinal canal diameter is safe and noninvasive. Its use should be further evaluated as part of a preemployment screening procedure for back pain.

摘要:

This study was undertaken to determine whether a specific group of hospital workers exposed to ethylene oxide (ETO) in sterilizing areas showed evidence of increased levels of sister chromatid exchange (SCE) formation. SCE frequencies were determined for 14 sterilizer workers and 14 matched controls. Time-weighted average (TWA) and peak ambient levels of ETO were measured in the sterilizing areas. Results indicated that all sterilizer workers were exposed to less than 5 parts per million TWA of ETO and that there were no statistically significant differences in SCE levels between sterilizer workers and controls. Smoking habits did appear to be associated with increased SCE levels. In this particular hospital setting no evidence of genetic effects stemming from employees' exposure to low levels of ETO was found.

摘要:

A spill of silicon tetrachloride (SiCl4) at a chemical plant caused the evacuation of several thousand people from an industrial park; 28 persons sought medical attention. Most of the affected individuals suffered only transient eye and upper airway irritation. Six of the plant employees were later referred for detailed evaluation of possible lung injury, but no definite evidence of SiCl4-induced pulmonary dysfunction was found. Five of these workers also experienced recurrent headaches, and two complained of pedal dysesthesias after the accident. Although the temporal relationship between the exposure and onset of these symptoms is notable, no definite etiologic relationship could be established.

摘要:

Executives with a low capacity for pleasure were examined to determine if they evidence less occupational and social success than those with normal or high capacity. Data on pleasure capacity and depressive symptoms were collected from 88 senior executive officers, and scores were compared with independent ratings of career success. The 11% of executives with serious work-related or personal problems showed significantly higher pleasure scores than the rest. It is hypothesized that the relatively high pleasure scores of the least successful executives reflect a defensive process of denial or reaction formation rather than an excessively joyful personality trait. A longitudinal study of executives is proposed to clarify whether the high pleasure capacity scores of the least successful executives change situationally over time.

摘要:

The use of wastewater for agricultural purposes involves the potential risk of infection from microorganisms in the wastewater. The application of partially treated wastewater on farms has been reported in one study to be associated with human illness, but this has not been confirmed. In the present study, workers at a land application system involving low-pressure spray irrigation of corn fields with wastewater were followed through a growing season to determine if they had an increased risk of infection as compared with a control population of the same socioeconomic group who had no direct exposure to wastewater. Enteroviruses were recovered from the wastewater used for irrigation, but not from the air during spraying. There was no increase in clinical illness among the workers and there was no evidence of an increased risk of infection. The workers who seemed at greatest risk, those who cleaned the spray nozzles, had higher antibody levels to one enterovirus, coxsackievirus B5, but acute symptomatic infections with viral excretion were not documented. This study indicates that there is very limited risk of infection among workers using partially treated wastewater for agriculture purposes.

摘要:

Cost of care and blood pressure control achieved were examined for individuals enrolled in two worksite hypertension control programs. In the first program, care was provided in a community-based setting by private physicians (model I-CBC); in the second program care was rendered by nurses under the supervision of a physician in work-based clinics (model II-WBC). In both situations, however, identification of employees with hypertension was effected through screening at the worksite. After adjustment for differences in labor market costs, annual average costs per client were found to be comparable for both programs. Blood pressure control (<160/95 mm Hg) was greater in model II-WBC than in model I-CBC. The average cost per unit of blood pressure reduction achieved by model II-WBC was $8.25 compared with $28.84 for model I-CBC, indicating a greater cost-effectiveness for worksite care programs.
