This study demonstrated that, occupations exposed to high-density quartz dust such as sandblasting workers, are at a much higher risk of developing PMF than other professions. No significant relationship was found between large opacity size and smoking status, concomitant tuberculosis, or duration of dust exposure. Objective: This study aimed to determine the occupational and clinical characteristics of patients with progressive massive fibrosis (PMF) and factors related to the development and severity of PMF. Methods: Personal, occupational, radiological, and functional findings of 129 patients diagnosed with PMF were evaluated. Results: Sandblasting workers were found to be diagnosed with pneumoconiosis at an earlier age than those in other professions. The dust exposure durations of sandblasting and ceramic workers were significantly less than those of workers in other occupations. Statistically, a significant negative correlation was found between lung functions and small opacity size, small opacity profusion score, and large opacity size. No relationship was found between large opacity size and smoking status, concomitant tuberculosis, and duration of dust exposure. Conclusions: An effective surveillance system that considers factors that accelerate pneumoconiosis progression should be established. [ABSTRACT FROM AUTHOR]

Objectives: It was aimed to determine the factors affecting the development of chronic obstructive pulmonary disease (COPD) in pneumoconiosis cases. Methods: Pneumoconiosis cases were divided into two groups as those with only pneumoconiosis and those with coexistence of pneumoconiosis and COPD. Demographic data, smoking habits, pulmonary function test, radiological findings, and occupational risk factors of the cases were compared. Results: Chronic obstructive pulmonary disease was detected in 134 of 465 pneumoconiosis cases (28.8%) included in the study. It was determined that patients who developed COPD were statistically significantly older, had longer exposure duration, had lower forced expiratory volume in 1 second, forced vital capacity, and forced expiratory volume in 1 second/forced vital capacity values, and had more pulmonary symptoms. Chronic obstructive pulmonary disease development was more common in sandblasting workers, dental technicians, and miners than in other occupations. Conclusion: It has been shown that the risk of developing COPD is high in cases of pneumoconiosis, independent of smoking, especially in certain occupational groups. [ABSTRACT FROM AUTHOR]
