摘要:

This study was undertaken to determine whether mortality from respiratory cancer among workers occupationally exposed to metallic nickel at the Oak Ridge Caseous Diffusion Plant (ORCDP) differed from that of workers at the same plant with no record of occupational exposure to metallic nickel or any nickel compound. A cohort of 814 nickel-exposed workers and one of 1600' controls were identified. The members of both cohorts had a minimum follow-up period of 19 years. Mortality from respiratory cancer and from other causes was examined in both groups. The data showed no evidence of an increased risk of mortality due to respiratory cancer among the nickel-exposed workers. The exposed cohort experienced lower mortality than the controls, both in deaths due to respiratory cancer and in deaths due to all causes, although neither of these differences was statistically significant.

摘要:

Hepatitis B is recognized as a major health hazard to hospital personnel. During a four-year period, 30 cases of hepatitis B were attributed to work at an urban medical center. Only four of these 30 individuals described a relevant accident in advance of their hepatitis and five others retrospectively suggested a specific episode that might have accounted for their illness. Early symptoms of' the illness were nonspecific and routine monitoring and clinical awareness are necessary for early diagnosis. All employees recuperated from their acute hepatitis, but one developed chronic active hepatitis. The incidence and morbidity of the disease emphasize the need for more effective control measures. The inconspicuous exposures responsible for the illnesses observed render it unlikely that any postexposure immune globulin prophylaxis will suffice in further reducing the incidence of hepatitis B.

摘要:

Carcinogenic effects of bee venom were evaluated in a mortality study of 580 occupationally exposed beekeepers. The subjects were identified through ovituary notices published between 1949 and 1978 in three journals of the U.S. beekeeping industry. Death certificates of beekeepers were examined for causes of mortality, and proportionate mortality ratios were compared with those for the general U.S. population, Beekeepers had a slightly lower than expected fraction of deaths from cancer. The deficit of lung cancers in male beekeepers was significant (P < 0.05) and may indicate that fewer beekeepers were cigarette smokers. The frequencies of other cancers did not differ significantly from expectation. Non-Hodgkin lymphoma developed in four persons, and was expected in two. Motality from diseases other than cancer showed no unusual patterns. At least two persons died from accidents directly related to the care of beehives. Analysis of a subgroup of 377 males woth major roles in the beeleeping industry showed no substantial differences in distribution of causes of death. This study of beekeepers reveals neither adverse nor beneficial effects of intense exposure to bee stings.

摘要:

As greater numbers of workers come under industrial hearing conservation programs, the problem of nonorganic hearing loss is becoming critical. The potential malingerer can be identified by behavioral observations both before and during the testing of hearing and by an analysis of test results. Manual, self-recording, and microprocessor audiometry all incorporate validity and reliability checks which assist in detecting the malingerer. Methods of documenting inaccurate hearing tests are detailed, along with ways of obtaining accurate follow-up tests. The key to alleviating the problem of malingering is early detection and immediate resolution of the problem.
