Denim sandblasting and silicosis two new subsequent cases in Turkey.

UNLABELLED In our country quartz is widely used for denim sandblasting and new cases with silicosis are defined. Silicosis is a preventable occupational lung disease caused by inhaled dust containing crystalline silica and no effective treatment for silicosis is available (1). CASE 1: A 23-years old man was admitted to the hospital with dyspnea on effort and cough. He had worked in a denim manufacturing factory for three years at sandblasting and dyeing. Physical examination revealed decreased breath sounds. Chest X-ray showed bilateral reticulonodular densities predominantly at middle and lower zones and minimal pneumothorax. Hypoxemia was determined in arterial blood gas analysis (BGA). Pulmonary function tests (PFTs) showed restrictive disorder. Lymphocytic alveolitis was demonstrated in the bronchoalveolar lavage fluid. Open lung biopsy revealed interstitial fibrosis and foreign particles which were seen more clearly under polarized light in interstitial areas. The patient was diagnosed as accelerated silicosis. CASE 2: A 25-years old man was admitted to the hospital with shortness of breath and haemopthysis. Two years ago, he had worked at the same place for 1.5 years. Bilateral reticulonodular densities at middle and lower zones and minimal unilateral pneumothorax were seen in chest X-ray. Restrictive disorder at PFT and hypoxemia in BGA were observed. Because of the similarity of complaints, radiological findings and occupational history with the former patient, no other further and invasive procedure was planned and the patient was diagnosed as accelerated silicosis. CONCLUSION The usage of sandblasted denims increase recently and denim sandblasting is being frequently made especially in small work places. Since there is no definite treatment for silicosis, it is important to take necessary precautions to improve the conditions of the factories.
