In 1953 Caplan, of the Cardiff Pneumoconiosis Medical Panel, recorded that massive pneumoconiosis was commoner in coal-workers suffering from rheumatoid arthritis than in those not subject to this condition. He also noticed that the radiological opacities in some of these arthritics had distinctive features which enabled him to distinguish them from the usual forms of massive fibrosis. The dist...

Pneumoconiosis is a systemic disease mainly caused by diffuse fibrosis (scar) of lung tissue due to long-term inhalation productive mineral dust in occupational activities and retention the lungs. The concentrration can be effectively controlled using water-based reduction technique. Therefore, investigation into water-clay interaction useful for pneumoconiosis prevention treatment. In this stu...

We report a case of lung cancer arising from progressive massive fibrosis (PMF) associated with pneumoconiosis. In this case, fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) was able to clearly distinguish the lung cancer from PMF, suggesting a potential usefulness of FDG-PET in cancer screening in patients with pneumoconiosis. To our knowledge, this is the first descripti...

Of 109 cases in England and Wales in which mycobacteria of the avian-Battey group were isolated from man 89 were considered genuine infections (including 32 with Mycobacterium avium) and six were doubtful. Almost half the significant cases were lung infections in men in dusty occupations, mostly coal miners with pneumoconiosis, and just over a quarter were non-pulmonary, mostly cervical adeniti...

Polyvinyl chloride is a widely used synthetic plastic polymer worldwide. Today, it in many areas, such as health, electricity, electronics, and construction, especially the building sector. It known to have harms human health. Our case 39-year-old male patient who has been working plastics industry for 16 years. The patient, was diagnosed with gastric neuroendocrine tumor while working, applied...
