To cite: Murlidhar V. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015209425 DESCRIPTION A 65-year-old non-smoker and former worker of the Hindustan Composites Asbestos factory, Mumbai, was screened at the Occupational Health and Safety Centre, Mumbai, which has helped diagnose and compensate occupational diseases including asbestosis since 1988. He had 28 yea...
A pilot study tested the feasibility of conducting occupational health research in Bangladesh while examining prevalence of asbestos-related diseases including asbestosis, work-related respiratory symptoms, and attitudes to occupational health and safety among a group of internal migrant ship breakers. Data was collected on clinical and work history, respiratory symptoms, and occupational healt...
The accurate diagnosis of asbestos-related diseases is important because of past and current asbestos exposures. This study evaluated the reliability of clinical diagnoses of asbestos-related diseases in former mineworkers using autopsies as the reference standard. Sensitivity, specificity, positive predictive value and negative predictive value were calculated. The 149 cases identified had cli...
Fibulin-3 has been reported as a potential biomarker for mesothelioma. However, little is known about the diagnostic efficacies of fibulin-3 for asbestos-related diseases (ARDs) in China. This study was to investigate the utility of fibulin-3 for asbestos exposure and ARDs. A total of 430 subjects were recruited from Southeast China, including healthy individuals, asbestos-exposed (AE) individu...
Pneumoconiosis is defined as the disease resulting from a chronic exposure to different inorganic dusts. In order to assess the lung defence against the effects of dust exposure, we studied the bronchoalveolar lavage (BAL) fluids from 30 silicotic patients (9 of them having a diagnosis of progressive massive fibrosis (PMF)) and 8 subjects with a diagnosis of asbestosis. Total protein content, N...
BACKGROUND Vermiculite from the mine near Libby, Montana, is contaminated with tremolite asbestos and other amphibole fibers (winchite and richterite). Asbestos-contaminated Libby vermiculite was used in loose-fill attic insulation that remains in millions of homes in the United States, Canada, and other countries. OBJECTIVE This report describes asbestos-related occupational respiratory dise...
OBJECTIVES To present a case of asbestosis and small cell lung cancer caused by asbestos in a clutch refabricator. METHODS Exposed surfaces of used clutches similar to those refabricated in the worker's workplace were rinsed, and the filtrate analysed by analytical transmission electron microscopy. Tissue samples were also analysed by this technique. RESULTS Numerous chrysotile fibres of re...
Inhalation of asbestos fibres leads to asbestosis of the pleura and the lung, with possible progression to lung cancer and malignant pleural or peritoneal mesothelioma. Asbestosis remains difficult to diagnose, especially in its early stages. The most important role in its diagnosis is that of chest radiographs. The aim of this cross-sectional study was to address interobserver variations in in...
Despite numerous published studies, debate continues regarding the risk of developing lung cancer among men exposed occupationally to asbestos, particularly those without radiographic or functional evidence of asbestosis. The beta-Carotene and Retinol Efficacy Trial (CARET), a study of vitamin supplementation for chemoprevention of lung cancer, has followed 4,060 heavily exposed US men for 9-17...
