RT Journal Article SR Electronic T1 The sociodemographic and clinical characteristics of Turkish workers with pneumoconiosis JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP p1056 VO 38 IS Suppl 55 A1 Hilal Altinoz A1 Cengiz Celikkalkan A1 Fatih Hamsioglu A1 Nalan Cengiz A1 Hikmet Orbay YR 2011 UL http://erj.ersjournals.com/content/38/Suppl_55/p1056.abstract AB Pneumoconiosis is an irreversible, preventable disease caused by dust inhalation. Although in other countries, by precautions the incidence decreased to 0,3-5%, it is still 10-15% in our country in pneumoconiosis causing occupations.We aimed to describe the characteristics of our 208 pneumoconiosis workers admitted to Istanbul Occupational Disease Hospital. Patient files between 01st Jan 2008 and 31st Dec 2010 are used for the descriptive study. All of the patients were male with 38,82±13 years of age. The most common workplace was Gaziosmanpasa with 27 cases. The mostly seen works were denim sandblasting, dental technicians, coal mining and casting (%50,5,%12,%6,7,%4,8). The most exposure material was silicium (86,5%). Mean exposure time was 9,9±8,9 years. Profusion according to the ILO classification was in the table. In 37 cases, there was an A opacity and B opacity in 28. The mean FEV1% was 67,27±23,3, FVC%73,78±20,86, FEV1/FVC%85,1±16 and KcO 102,74±28,1. The period between exposure and symptoms were calculated as 10,48±8,7 years. Patients were mostly referred by a social security center, secondly by Sureyyapasa training hospital and thirdly, admitted by themselves. The most common symptoms were breathlessness, cough and exertional dyspnea. The exposure time in a workday is very important but in our files there were no data showing this, so we planned to rearrange our patient files.View this table:Radiographic profusionGenerally each paper in the literature discusses only one type of occupation causing pneumoconiosis. To our knowledge this is the first study concerning nearly all occupations causing the disease.
