Lung disease with chronic obstruction in opium smokers in Singapore: Clinical, electrocardiographic, radiological, functional, and pathological features

AUTOR(ES)
RESUMO

Fifty-four opium smokers with chronic obstructive lung disease were studied for two-and-a-half years. Forty-eight patients had a cough for at least two years before the onset of inappropriate exertional dyspnoea. Fine, bubbling adventitious sounds suggesting small airway disease were heard on auscultation over the middle and lower lobes in 38 patients.
