Two Cases with Silicosis Caused by Denim Sandblasting

Silicosis which is one of the oldest known occupational diseases is characterized by an irreversible and progressive fibrotic reaction occuring in the lungs caused by inhaling crystalline silica dust. Effective treatment for silicosis is not available. Recently, denim sandblasting especially being made in uncontrolled small-scale workplace in primitive conditions has been a striking occupation leading to silicosis . Twenty and 28 years old male patients who work in denim sandblasting for 3 years were admitted to our clinics with complaints of dyspnea and loss of weight. Chest X ray and thorax computerized tomography revealed bilateral diffuse reticulonodular and nodular opacities which were prominent in the upper and middle zones and peripheric area of pulmonary parenchyma. Restrictive disorder was observed at their pulmonary function tests. Silicosis was diagnosed by performing transbronchial biopsy in one case. Because of the similarity of complaints, radiological findings and occupational history with the former patient, no other further and invasive procedure was performed and the other patient was also diagnosed as silicosis. In developing countries in which the labor force is very cheap, silicosis becomes a public health problem in denim sandblasters and can be prevented with improvement of working conditions. We believe that further precaution must be taken to stop darkened lives while jeans is bleaching. Key Words: Denim Sandblasting; Silicosis.
