摘要:

Female radium dial workers first employed before 1930 were analyzed for breast cancer mortality and incidence using method and rate tables described by Monson and the Mantel-Haenszel summary chi-square test for significance. Of 1,180 located women, 736 were measured to estimate radium intake. This measured group was analyzed for breast cancer mortality and incidence according to four possible risk factors: radium intake dose, duration of employment, age at first exposure, and parity. The located women had a mortality ratio of 1.51 (p < 0.05). The measured women showed a significant excess of breast cancer incidence and mortality only among those women with a radium intake of 50 µCi or greater. Although the differences were not significant, incidence and mortality ratios were slightly higher for nulliparous women.

摘要:

A patient admitted to a general medical ward for evaluation of jaundice was transferred to an intensive care unit when he developed a hemorrhagic diathesis and hepatic encephalopathy. Fifteen days elapsed before it was recognized that the patient was infected with hepatitis B virus (HBV), during which time the staff took no precautions other than routine hand washing. On subsequent evaluation of risk, it was decided that administration of an immunoglobulin preparation was not indicated despite the patient's massive contamination of his immediate environment. Of 89 persons heavily, casually, or indirectly exposed, none developed clinical illness within six months following contact. A nurse, first tested 30 days after contact, was persistently hepatitis B surface antigen-positive, but results of testing for antibody to core antigen demonstrated she was a long-term carrier. Among 67 susceptible staff members tested serially, none had serologic evidence of HBV infection. Thus, not all HBV-infected patients are highly contagious. Nonetheless, procedures to prevent such unprotected exposures are needed.

摘要:

One of the basic problems in monitoring exposure of nickel refining workers has been the unclear correlation between plasma nickel, urine nickel, and airborne nickel during the eight-hour work period or throughout the 24-hour day. In previous studies the authors have demonstrated the value of biological sampling in an occupational health program in the nickel processing industry.1 2 3Whether a single plasma or single urine sample is an adequate gauge of exposure or whether 24-hour urine specimens or a threeday average plasma level are more accurate indices remained to be determined.The purpose of this paper is to report the results of studies of diurnal variations which affect the significance of single biological samples. In addition, data gathered on the correlation of plasma and urine nickel levels with soluble and insoluble nickel compounds in the atmosphere are presented.

摘要:

Guidelines for employment and placement of the diabetic in industry have been updated. These guidelines are intended to help the physician in his recommendations to management for hiring and job placement so that a safe work environment is insured for both the diabetic and the non-diabetic.

摘要:

Serum creatine kinase (CK) was significantly higher (p < 0.02) in 69 patients examined for occupational intoxication from solvents than in 96 non-exposed control subjects. A needle muscle biopsy was performed in nine patients randomly selected from the patients with elevated levels of serum CK. A higher activity of muscle lactate dehydrogenase (LDH) (p <0.05) and a lower activity of muscle succinate dehydrogenase (SDH) (p < 0.01) was found in the patients when compared with 76 non-exposed control subjects. No histological abnormalities were observed using light microscopy. The elevated serum CK represented the serum CKMisoenzyme fraction. It is concluded that skeletal muscles should be added to the list of organs involved in intoxication from solvents and that serum CK should be analyzed in solvent-intoxicated patients as an indicator of myopathy.

摘要:

Neurologic examination, nerve conduction testing and electro-oculographic testing have been performed at a baseline examination and a follow-up examination in a group of lead workers with blood lead levels predominantly between 60 and 80 μg/dl and in a group of control workers. A statistically significant decreased saccade accuracy measurement in the lead workers compared to the controls was found at both examinations. No other simple test or pattern of findings differentiated between the lead workers and the controls, and the biological significance of the lower saccade accuracy is not clear. Nerve conduction measurements do not appear to be a satisfactory method of detecting subclinical neurologic effects of lead exposure.
