The study was designed to test the hypothesis that the risk of lung cancer from asbestos exposure is confined to persons with radiographic evidence of pulmonary fibrosis. Occupational and smoking histories were obtained from 271 patients with a confirmed diagnosis of primary lung cancer and 678 referents (279 with other respiratory disease and 399 with cardiac disease). Histories were reviewed ...
Effect of a two-hour training on physicians' skill in interpreting Pneumoconiotic chest radiographs.
OBJECTIVE Occupational lung diseases have specific radiographic manifestations not always well known by physicians. In Japan, asbestos-related diseases became a public health concern after the "Kubota Shock", when a number of workers and residents living nearby a manufacturer of asbestos-made ducts developed mesothelioma caused by asbestos exposure. This preliminary intervention trial evaluated...
Plain chest radiographs from a one in six random sample of the workforce of the asbestos industry at Wittenoom, Western Australia between 1943 and 1966 have been classified for degree of profusion and pleural thickening by two independent observers according to the 1980 UICC-ILO Classification of Radiographs for the pneumoconioses to clarify the effect of degree of radiological abnormality on s...
OBJECTIVES Current situation in the epidemiology of occupational diseases is a resultant of many contributing factors, such as occupational exposures of the working population, social and economic conditions, medical measures, legislation, and ongoing changes in the national economy. MATERIALS AND METHODS This work is based on the information compiled from reporting forms on occupational dise...
The WHO has ranked environmental hazardous exposures in the living and working environment among the top risk factors for chronic disease mortality. Worldwide, about 40 million people die each year from noncommunicable diseases (NCDs) including cancer, diabetes, and chronic cardiovascular, neurological and lung diseases. The exposure to ambient pollution in the living and working environment is...
In recent years the greatest progress in our understanding of pneumoconioses, other than those produced by asbestos, silica, and coal, has been in the arena of metal-induced parenchymal lung disorders. Inhalation of metal dusts and fumes can induce a wide range of lung pathology, including airways disorders, cancer, and parenchymal diseases. The emphasis of this update is on parenchymal disease...
The 60-film set was developed by experts (Expert Group) for examining 8 indices: sensitivity (X(1)) and specificity (X(2)) for pneumoconiosis, sensitivity(X(3)) and specificity for (X(4)) large opacities, sensitivity (X(5)) and specificity (X(6)) for pleural plaque, profusion increment consistency for small opacities (X(7)), and shape differentiation for small opacities (X(8)) of physicians' re...
OBJECTIVES Epidemiological reports since 2000 have documented increased prevalence and rapid progression of pneumoconiosis among underground coal miners in the United States. To investigate a possible role of silica exposure in the increase, we examined chest x-rays (CXRs) for specific abnormalities (r-type small opacities) known to be associated with silicosis lung pathology. METHODS Undergr...
INTRODUCTION Silicosis, the most prevalent of the pneumoconioses, is caused by inhalation of crystalline silica particles. Silica-exposed workers are at increased risk for tuberculosis and other mycobacterium-related diseases. The risk of a patient with silicosis developing tuberculosis is higher (2.8 to 39 fold higher, depending on the severity of silicosis) than that found in healthy controls...
