Increased mortality from cancer of the lung has been found in several studies of miners exposed to high levels of radioactivity in underground air. In view of their exposure to raised levels of radiation, we have studied the mortality of a group of men recorded as Cornish tin miners in 1939. Using occupational description, a crude classification of exposure was derived for these miners. The mea...

a 69-year-old woman was admitted to hospital 4 times from november 2007 to june 2009. the patient had silicosis complicated by broncholithiasis, esophagobronchial fistula, and relapsed tuberculosis. she had worked as a stone crusher for 3 years and was exposed to a large amount of quartz dust. barium esophagography, gastroesophageal endoscopy, and biopsy suggested esophageal-related chronic inf...

Background: Long-term exposure to silica dust makes people prone for silicosis which raises the risk of individual in developing pulmonary tuberculosis (PTB). Silicosis is a progressive lung disease characterize with shortness breath, cough, fever, and bluish skin, caused due inhalation crystalline found abundance sand, rock, quartz. Aims Objectives: The known effect functioning macrophages mak...

Introduction: Silicosis is a progressive, fibrotic and preventable occupational lung disease. Occupational exposure in stone crushing units to silica particles of size 0.5 to 5μm poses a hazard to the workers. Methods: Our study is a passive surveillance study of silicosis in the symptomatic workers referred from Occupational Disease Centre to Department of Radiodiagnosis for chest X-Ray and Hi...
