摘要:

AbstractA previous proportionate mortality ratio analysis revealed elevated mortality from brain tumors, stomach cancer, leukemia, and other cancers among OCAW members employed in three Texas oil refineries. In order to evaluate these findings, complete work histories of cases and a matched set of controls who died from other causes of death were obtained from company personnel records. Work histories were summarized by classifying each job title and department entry into one of several broad work categories of refinery unit operations. A worker was considered “exposed” to a work category if he was known to have worked at least 1 day in the category 15 or more years prior to his death. Maximum likelihood estimates of the relative risk for brain tumor, stomach cancer, and leukemia were calculated by work category using a procedure for matched case‐control data. No strong associations for brain tumor risk were seen with any work categories. A slight association for leukemia was seen among workers in the Treating category, which included unit operations that reduce the level of aromatic and sulfur constituents of petroleum products and combine them with additives to improve their quality. Stomach cancer risk was elevated among maintenance workers and workers exposed to lubricating oils and paraffin wax proce

摘要:

AbstractOrganophosphate (OP) and carbamate poisoning are still a worldwide health problem causing numerous fatalities in humans. Physicians who have no clinical toxicological experience with these compounds may have difficulties in promptly identifying the etiologic agent and managing the acute phase of the poisoning. We describe the potential use of a computerized medical information system that includes clinical data on 236 cases of OP and carbamate poisoning, and may improve the management of such poisoning. The methods of constructing the system, the first results of using the system, and the medical institutions that can benefit from such systems are discussed.

摘要:

AbstractNineteen men who had been exposed to asbestos for long periods were subjected to an examination of the lungs by means of computerised axial tomography (CT). Some features of asbestos‐related disease are shown better on CT than on conventional roentgenograms, and occasionally features not shown at all on conventional films may be demonstrated on CT. It was concluded that CT may be useful in cases with borderline and doubtful signs on conventional films, and very occasionally in persons with long exposure who have normal conventional film

摘要:

AbstractNeuropsychological tests and self‐report personality inventories were administered to 14 workers and rescue squad personnel approximately 2 months following mild exposure to pentaborane, a highly toxic volatile liquid boron hydride. Performance decrements were evident on 5 of 11 neuropsychological tests, including Block Design and measures of sustained attention and recent memory. Neuropsychological deficits were not related to emotional changes reported on the Hopkins Symptom Checklist nor to the presence of CT scan abnormality. These results indicate mild residual brain dysfunction following pentaborane intoxication, including possible dysfunction in subcortical regions mediating memory processes and in cortical areas mediating visuo‐spatial abilit

摘要:

AbstractOne hundred ninety‐one workers in three different occupations were examined regarding presence of symptoms from the cervicobrachial region. Eighteen percent of the workers (27% of the female and 11% of the male workers) had symptoms of compression in the thoracic outlet. However, only 2% of all workers had pronounced symptoms of compression in the thoracic outlet. In addition, 27% of the workers (33% of the female and 23% of the male workers) had symptoms of other cervicobrachial disorders. Thus, 45% of the workers had symptoms from the cervicobrachial region. The workers with symptoms of compression in the thoracic outlet were significantly younger than the workers with other symptoms of cervicobrachial disorders, p<0.01. No significant correlation was noted between vascular compression and symptoms of compression in the thoracic outle

摘要:

AbstractThe occurrence of permanent arterial hypertension was studied among the workers of a textile plant (490 subjects) exposed to high frequency noise, at levels often exceeding 100 dBA. The prevalence of the disease among these workers was compared to that observed in a reference series (450 subjects). A prevalence rate ratio equal to 1.34 (1.14–1.57) was estimated, taking into account several determinants of disease acting as confounding factors in the study. The results, which are in good agreement with those obtained in similar studies, are discusse
