"Health activities carried out in 1975 by NIOSH under the Federal Coal Mine Health and Safety Act of 1969 were described. Activities included periodic medical services for coal miners, extensive research in pulmonary diseases, setting occupational standards in coal mining industrial health programs, and paying for postmortem examinations of miners and former miners. The medical services included physical examinations, chest x-ray examinations for working miners, and postmortem studies of other miners. Of 56,575 men participating in the second round of chest x-ray examinations between July of 1973 and March of 1975, lung cancer was suspected in about 750 of them, marked emphysema was noted in more than 3,500, and evidence for tuberculosis, usually inactive, was noted in more than 3,000. Research designed to improve the health of coal miners was divided into five major areas: early diagnoses, epidemiological studies, infectious disease studies, laboratory investigations, and toxicologic studies. The major epidemiological study was devoted to coal workers' pneumoconiosis. Infectious disease research was directed toward evaluating the interactions of mineral dusts and infectious agents, assessing miner susceptibility, and developing the techniques for identifying and treating persons who are or who might become susceptible to repeated respiratory tract infections. Interagency activities have involved the Food and Drug Administration, the Department of Labor, the Coal Mine Health Research Advisory Committee, the Interim Compliance Panel, and the Department of the Interior." - NIOSHTIC-2
"The health activities fulfilling NIOSH responsibilities under the Federal Coal Mine Health and Safety Act of 1969 are reported for the calender year 1974. The extensive medical examination services coordinated at the NIOSH Appalachian Laboratory for Occupational Respiratory Diseases (ALFORD) in Morgantown, West Virginia processed 46,896 chest x-rays of active underground coal miners by the end of 1974. Although this second round of examinations which began in 1973 is not complete, 5,714 (over 13%) x-rays showed some evidence of coal workers' pneumoconiosis and progressive massive fibrosis was seen in 239 cases. By the end of 1974, 1,059 physicians had demonstrated competence in the use of the official clsasification systems for x-rays. Preliminary results from the second round of the National Study of Coal Workers' Pneumoconiosis in which 4,072 underground coal miners were examined showed significantly lower prevalence of pneumoconiosis compared with the results from the first round completed in 1971, but this is considered to reflect change in miner sample rather than general improvement in total miner health. The National Coal Workers' Autopsy Service had accepted 628 post mortem examinations during 1974. Coal mine health research during 1974 included community surveys, biochemical techniques for diagnosis and early detection, and study of the mechanism by which lung function is altered by pneumoconiosis as well as genetic aspects, infectious diseases, and cellular and tissue reactions to coal dust.
