Pneumoconiosis as an occupational disease is a serious threat to the health of workers. Patients with pneumoconiosis are mainly engaged in dust-related work such as gold, coal, or iron mining, electric welding, or road work, and present with miliary nodules, fuse mass-like opacities, and cavity lesions on chest imaging. Clinical manifestations of pneumoconiosis include progressive chest tightne...

The purpose of the study was to determine the relationship between pneumoconiosis and congestive heart failure (CHF).We collected data from the National Health Insurance Research Database in Taiwan. The study sample comprised 8923 patients with pneumoconiosis and 35,692 nonpneumoconiosis controls enrolled from 2000 to 2011. Patients were followed up until the end of 2011 to evaluate the inciden...

At a conference on coal-workers' pneumoconiosis called in Cardiff in January 1947 by the Minister of Fuel and Power, it was suggested that it might be possible to re-employ men certified as cases of coal-worker's pneumoconiosis in the briquetting industry, in which the Minister anticipated an expansion. The Industrial Pulmonary Disease Committee of the Medical Research Council subsequently disc...

BACKGROUND Pneumoconiosis is a form of diffuse interstitial lung disease, often resulting from occupational exposures. As dental prosthetic technicians (DPTs) build prostheses, they are exposed to many chemical materials that increase their risk of developing pneumoconiosis. AIMS To document pulmonary function and prevalence of pneumoconiosis in DPTs. METHODS A cross-sectional study of DPTs...

Circulating antinuclear antibody and rheumatoid factor have been measured in 109 coal miners with pneumoconiosis whose chest radiograph showed a range of abnormalities varying from simple pneumoconiosis of mild degree to advanced progressive massive fibrosis.At a screening dilution of 1/10 the overall incidence of antinuclear antibody was 17%. In almost half of the positive cases the titre was ...

Background: Pneumoconiosis occurs almost in entire worldwide. had threatened cement workers. Serologic abnormalities found pneumoconiosis. Surfactant Protein A (SP-A) levels increased silica-exposed may be a helpful biomarker for the early diagnosis of pneumoconiosis, but it has not yet been studied Indonesia.Methods: The design this study was observational with cross-sectional. sampling cement...

Pneumoconiosis is still a health problem in Turkey and has a relatively high incidence. Retired underground miners were investigated to document alveolitis, and to observe the difference in the cellular profiles of bronchoalveolar lavage (BAL) fluid with or without pneumoconiosis. Twenty nine retired male miners and 17 controls, eight non-smokers (four male, four female) and nine smokers (six m...

Extensive surveys carried out in Europe and America have shown the incidence of coalworkers' pneumoconiosis to be widespread (Flinn, Seifert, Brinton, Jones, and Franks, 1941; Fletcher, 1955). In India, however, the prevalence of this disease has never been investigated, and a report published by the government of India in 1946 (Deshpande, 1946) stated that there was no conclusive evidence that...

As the tuberculous hypothesis of coal-workers' progressive massive fibrosis (P.M.F.) is not so strongly held nowadays the possible importance of genetic factors should be explored. Twins with pneumoconiosis should provide helpful information. Details are given of two pairs of twins; one pair is considered to be monozygotic and the other dizygotic. Blood grouping, secretor state, and Rose Waaler...
