Evolution of disability in coalworkers' pneumoconiosis.
Retrospective analysis of the results of serial ventilatory capacity tests (FEV 1-0), which had extended over an average period of almost 15 years, has been carried out in 215 miners and ex-miners who suffer with coalworkers' pneumoconiosis. All were unselected previously diagnosed cases who attend the Cardiff Pneumoconiosis Panel at regular intervals for re-assessment examinations. They consis...
متن کاملRelationship between type of simple coalworkers' pneumoconiosis and lung function. A nine-year follow-up study of subjects with small rounded opacities.
One hundred and twenty-five men who were identified in 1968 as having the simple pneumoconiosis of coalworkers were re-examined nine years later when their mean age was 59.6 years. On both occasions the lung function and response to exercise were assessed. There was no evidence for progression of simple pneumoconiosis between the surveys, but 14 had developed small irregular opacities on their ...
متن کاملCoalworkers' simple pneumoconiosis and exposure to dust at 10 British coalmines.
Five physicians' radiological assessments of coalworkers' simple pneumoconiosis (CWP) in 2600 coalminers at 10 British collieries have been studied in relation to the individuals' estimated lifetime (mean 33 years) exposure to respirable coalmine dust. Estimates of exposure were based on 20 years of observations at each colliery. Radiographic classifications were clearly associated with the mea...
متن کاملRight ventricular hypertrophy in a group of coalworkers.
The prevalence of right ventricular hypertrophy was studied in necropsy material from 215 coalworkers, a group which consisted of 115 men with simple or no pneumoconiosis and 100 with progressive massive fibrosis. Right ventricular hypertrophy was considered to be present if the ratio of the weight of the left ventricle plus septum to that of the right ventricle was less than 2:1. The prevalenc...
متن کاملA controlled trial of anti-tuberculosis chemotherapy in the early complicated pneumoconiosis of coalworkers.
A controlled trial in coalminers under the age of 50 in South Wales with sputum-negative, early complicated pneumoconiosis was used to compare three regimes: (1) chemotherapy (rest in hospital and 1 g. streptomycin, 200 mg. INH, 10 g. PAS, for 3 months; then 200 mg. INH, 10 g. PAS for 9 months); (2) rest (in hospital for 3 months); and (3) a working group. The initial and three-year radiographs...
