Lung Function in Coalworkers' Pneumoconiosis

Cardiac hypertrophy in coalworkers' pneumoconiosis.

Irregularly shaped small shadows on chest radiographs, dust exposure, and lung function in coalworkers' pneumoconiosis.

The predominant shapes of small opacities on the chest radiographs of 895 British coalminers have been studied. The aims were to determine whether irregular (as distinct from rounded) small opacities can be identified reproducibly, whether their occurrence is related to dust exposure, and whether they are associated with excess prevalence of respiratory symptoms or impairments of lung function....

Mortality in Coalworkers' Pneumoconiosis Related to Lung Function: a Prospective Study.

In 1949, 126 coalminers, chosen to cover the whole radiological range of coalworkers' pneumoconiosis, were subjected to a battery of physiological tests of lung function, clinical investigations, and anthropometry. During the ensuing 12 years 40 of these men died. An analysis of the original measurements was carried out in an attempt to identify the particular features of the disturbance of lun...

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...
