Primary lung cancer in South Wales coal-workers with pneumoconiosis.

Coal-workers in the southern part of Wales are particularly prone to pulmonary disease due to the inhalation of coal dust. In some men discrete foci of dust are scattered more or less uniformly throughout both lungs. This is called simple pneumoconiosis. In others there occur also one or more large localized masses of dust and dense fibrous tissue (Fig. 1). This manifestation is referred to as ...

Twins with coal-workers' pneumoconiosis.

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...

Airway function and respiratory resistance in Taiwanese coal workers with simple pneumoconiosis.

BACKGROUND Occupational exposure to coalmine dust consisting of coal particles and free silica eventually results in massive lung fibrosis. However, clinical observations of patients with coal workers' pneumoconiosis (CWP) suggest that airway dysfunction may be a predominant feature in the initial development of the disease. METHODS Forced expirogram, plethysmographic determination of lung vo...
