A good number of pneumoconiosis patients come to visit our clinic which, along with the "the Miyagi Health and Welfare Association" Juridical foundation to which it belongs, treats about 300 patients. The Hosokura mine, in northern Miyagi Prefecture, ended its 1200 year history when the mountain was closed about 10 years ago, and its former miners' health problems turned into social problems. We carried out physical examinations for pneumoconiosis and vibration syndrome and have undertaken diagnosis, treatment, workmen's compensation application, etc. Among those who had resigned from their jobs, there were those who made great progress in fighting work related illness along with a few confirmed examples of newly developed large shadows of aggregated by using positron CT that illustrate the progress of pneumoconiosis through 10 years after leaving their jobs, which were reported to the Japan Society for Occupational Health and The 9th International Conference on Occupational Respiratory Diseases. In this process, mainly in trials, I found continuing controversy on quite a few points. Moreover, I thought that these comment contents would contrast fairly with information from academic conferences and study meetings. In our country, metals mining and coal mining have nearly vanished as an industry. However, with new road and railroad construction, work contributing to pneumoconiosis should continue to propagate. The range of risk bearing occupations includes many more jobs than just mining. Also, former miners - those workers retired after the mine closure - risk the possibility of developing diseases even after resigning from their jobs, while becoming dependent upon family and friends and dispersing themselves through the whole country. Understanding various opinions including "minimization of pneumoconiosis", confirmation and diffusion of basic knowledge of pneumoconiosis while addressing occupational health and safety issues is certainly one of my professional responsibilities as a respiratory physician. The contents explored through this Question and Answer forum do not tell the whole story of pneumoconiosis. For example, some groups of people from in our country are of the opinion that the "Carcinogenesis Reports of Silicic Acid" by the IARC are "ineffective" for trial evidence, and other noticeable items are discussed most actively with main points summarized in (I) Problems of pneumoconiosis law and application. If there are any questions or comments that arise in light of these contents' disclosure, by all means contact me by e-mail or other means as I would like to add to and complete these contents. Also, because I am planning publication in the form of a book later, please contact me regarding inaccurate or indistinct points.
