摘要:

A previous retrospective follow-up mortality study of white men employed at an oil refinery found an excess of leukemia deaths, especially of acute myeloid leukemia (AML). A casecontrol studv was done to determine if the excess could be related to any particular jobs or departments at the refinery or to benzene exposures. The study includes 14 cases with leukemia (eight cases with AML) and 60 matched controls. No particular job or department was identified as the likely source of the excess leukemia deaths. Furthermore, the cases apparently had not been exposed to more benzene than had the controls. Thus, the reason for the excess leukemia at this refinery was not identified. The limitations of the study are discussed.

摘要:

Contract health care plans exclude workers' compensation from among the prepaid medical benefits. Under present contract relationships, compensable injury and illness can be billed to the employer as fee-for-service care. The provision of health care, normally an expense for the prepaid health care provider, generates income when it is given under a compensation rubric. Per capita workers' compensation costs at eight federal shipyards range from less than $600 in yards with no health maintenance organization (HMO) coverage to more than $1,000 in yards with more than two-thirds of employees enrolled in prepaid health care plans. A statistically significant relationship between prepaid health care plan enrollment and per capita workers' compensation costs at these yards suggests the likelihood of systematic cost-shifting by overdiagnosis of compensable injury and illness. Changes in prepaid contract incentives may improve the ethical and economic health care climate for workers' compensation.

摘要:

In order to assess the extent of polychlorinated biphenyl (PCB) exposure and potential health effects, a clinical-epidemiologic survey was initiated among 205 workers at a capacitor manufacturing plant. The geometric mean serum PCB level for workers was 18.2 ppb (SD 2.88), with a range of 0 to 424 ppb. Multiple regression analysis found duration of employment, cumulative occupational exposure, cumulative fish consumption, and cholesterol level to be significant predictors of log serum PCB levels. Of these predictors, duration of employment and cumulative occupational exposure were the strongest contributors to the regression model, indicating the dual importance of opportunity for dermal contact and respiratory exposure level in contributing to workers' serum PCB levels.

摘要:

Mesquite wood charcoal has been widely promoted for the unique taste it imparts to broiled food. We recently examined a 21-year-old mesquite broiler cook with evidence suggestive of respiratory allergy or irritation following exposure to mesquite broiler smoke in a Salt Lake City restaurant. We subsequently surveyed 13 mesquite and 17 gas-flame (“charcoal”) broiler cooks to determine the prevalence of respiratory symptoms among workers exposed to broiler smoke. The survey demonstrated statistically significsnt (P ≤ .05) respiratory irritation in the mesquite broiler group compared with the gas-flame broiler group in one of four symptom categories. Two other symptom categories strongly suggested the presence of (PC < 10) respiratory irritation in the mesquite broiler group. Personal air sampling was conducted on two mesquite broiler cooks and two gas-flame broiler cooks and compared. Unidentified saturated and unsaturated aliphatic hydrocarbons (C8 through 012) with high molecular weights from 108 to 182 were present in air samples from the mesquite broiler cooks and not in the air samples from the gas-flame broiler cooks.

摘要:

An historical cohort mortality study of research and development personnel (primarily chemists) actively employed on Dec 31, 1961, with at least 1 year of service with the Allied Corporation was carried out. These employees experienced lower mortality for all causes of death combined and all cancer causes combined than would be expected on the basis of the general US population. The degree of deficit in all causes of death combined was below the healthy worker effect usually associated with occupational mortality studies of production workers. There was one statistically significsn t excess, that for cancer of the prostate among research laboratory personnel who worked during the period 1946 to 1966, a period during which researchers may have been exposed to insecticides or fluorine derivatives. Substantial deficits were observed for causes of death known to be related to life-style, suggesting that mortality among Allied's salaried employees, including research and development workers, may have been influenced more by these factors than by occupational factors.
