With interest, I read the recent analysis by Tomaskova and co-workers (2017) about mortality from coal workers' pneumoconiosis (CWP). The research question remains unclear whether coal workers' pneumoconiosis (CWP) resulting from exposure to respirable coal dust containing crystalline silica accelerates the development of lung cancer or whether it is an intermediate stage in the pathway. I made...

BACKGROUND The aim of this study was to evaluate factors associated with increased risk of mortality from pneumonia among patients with pneumoconiosis. METHODS Medical records of 103 pneumoconiosis patients hospitalized for pneumonia were investigated. Seven patients who had lung cancer or other malignancy and 13 patients with insufficient medical record were excluded. Two female patients wer...

1.1 Overview on pneumoconioses Pneumoconiosis is an occupational lung disease caused by the exposure to dust. This section summarizes the generalities on pneumoconioses, including definitions, epidemiology and clinical manifestations of those occupational and environmental lung diseases. The most important step in the diagnosis of pneumoconiosis in to question the subject regarding specifics of...

Accepted 29 July 1996 Abstract Objective-To determine whether previous health experiences affect the prevalence of occupational lung disease in a semirural Botswanan community where there is a long history of labour recruitment to South African mines. Method-A cross sectional prevalence study of 304 former miners examined according to a protocol including a questionnaire, chest radiograph, spir...

In the absence of adequate preventive measures the manufacture of carbon electrodes is attended by a considerable dust hazard. The present paper is based on a study of the clinical, radiological, and pathological changes resulting from inhalation of this dust, which is derived from crushed coke and anthracite. An account is given of the findings in a clinical survey of 15 men who had been emplo...

A group of 17 738 working miners, medically examined during 1953-8, were followed up from 1974 to 1980. Of the 7118 men re-examined, 2547 were still working miners and 4526 had left the industry (45 were of unrecorded status). The incidence of progressive massive fibrosis (PMF) over an average follow up period of 22 years among men who had remained in the industry was 27 per 1000, but 94 per 10...

In previous work (Thomas, 1951; James and Thomas, 1956), we have been made aware of some problems of pulmonary heart disease that needed further elucidation. Further consideration of the method of assessment of right ventricular hypertrophy and its relation to emphysema and pneumoconiosis when present, separately or together, was needed. Jaffe (1934), referred to the lesion of pneumoconiosis as...

BACKGROUND Gold mineworkers in South Africa are exposed to high levels of silica dust as a result of which they are at risk of developing silicosis, which is a compensable disease. The incidence of tuberculosis is also high. METHODS To determine the prevalence of occupational lung disease and the previous compensation history in former migrant mineworkers, a study was undertaken in a random s...
