Coal workers' pneumoconiosis

Abstract

CWP is a disease distinct and separate from silicosis. Simple CWP is clearly related to the amount of dust deposited within the lungs. Complicated CWP (PMF) results from dust deposition plus other factors. Immunologic and local cellular factors may contribute to the development of this form of the disease. Studies of lung cell response and function may further elucidate mechanisms and mediators of lung dust reaction. Complicated CWP (PMF) is clearly associated with alterations in ventilatory, mechanical, and vascular function of the lungs. These abnormalities in PMF contribute to the observed premature morbidity and mortality of this disease.
