Black and Brown Lung Disease

programs of disability compensation and medical care.

Opinions about the distribution and incidence of the conditions have been linked to competing views about their clinical manifestations and pathology. For many years and in many communities, physicians did not differentiate the symptoms of black and brown lung from those of other common respiratory disorders. In the early stages of both diseases, workers are frequently asymptomatic and without functional impairment. For black lung defined medically as CWP, the progression of symptoms often includes chronic cough and phlegm, shortness of breath, and then functional impairment; but some workers with lesions of CWP at autopsy remained free of symptoms. The initial symptoms of byssinosis are tightness in the chest, dyspnea, and a cough following a return to work after a weekend or holiday. Later symptoms extend to other workdays and include a chronic stage, with severe continuous dyspnea, chronic cough, and permanent ventilatory insufficiency.
