Although a diagnosis of TB was confirmed on sputum cultures, coexistence of a concomitant pneumoconiosis (eg, silicosis in this case) cannot be ruled out because there is a history of exposure to the cement industry. Silicotuberculosis is a well-described entity in literature, and it is said that silicosis increases the predisposition toward TB. [2] The parenchymal nodules on chest radiograph a...

Sandblasting denim using silica has emerged as a new cause of silicosis in Turkey. Following the discovery of several cases of silicosis in (young) workers who used this process, the frequency and main occupational risk factors of silicosis among former denim sandblasters in the region of Erzurum (Turkey) were evaluated. Demographic characteristics and information on working conditions were obt...

BACKGROUND Silicosis is one of the oldest occupational lung diseases, but it continues to cause significant morbidity and mortality worldwide. AIMS To report cases of silicosis presenting to two specialist respiratory clinics. METHODS A retrospective analysis of prospectively collected data of cases of silicosis in workers referred to specialist respiratory clinics. RESULTS Over the cours...

background: the term crystallized silica refers to the crystallized form of sio 2 and quartz, the most frequency composition in the earth’s crust that can cause silicosis and lung cancer through occupational exposure and inhalation of its large quantities. methods: occupational exposure of workers in pakdasht, iran, in 2011 was investigated in four different casting processes in small foundries...

BACKGROUND Eliminating silicosis is a priority of the International Labour Organization and the World Health Organization. Prevalence is particularly high in developing countries. OBJECTIVES We describe trends in silicosis among South African gold miners who had had an autopsy between 1975 and 2007 and quantify the contributions of age at autopsy and employment duration to these trends. MET...

Since its inception in 1886, high rates of occupational lung disease, particularly “miners’ phthisis” (silicosis and/or pulmonary tuberculosis) and accompanying racial disparities have been a feature of the South African gold mining industry. While mortality from silicosis and pulmonary tuberculosis fell among white miners during the first half of the 20th century, there was scanty information ...

INTRODUCTION Co-existence of silicosis and tuberculosis is known as silico-tuberculosis. This article review the frequency of silicosis and tuberculosis in workers who exposed to silica and evaluate influencing factors that may increase the risk of silico-tuberculosis. METHODS An analytical cross-sectional study was performed in silica exposed workers in central province of Iran during 2011-2...

Silicosis is a well-known occupational lung disease that was discovered by the ancient Greeks and Romans. In 2001, it has emerged again in an unexpected occupation: denim sandblasting. Exposure to crystalline silica, with or without clinical disease, is one of the most important predisposing factors for the development of tuberculosis; however, there has been no previous report of tuberculosis ...

I report pleural effusion in a patient with silicosis of the lung and pulmonary massive fibrosis. No specific aetiology for the effusion was detected after thorough investigation and a long follow up period. I speculate that, similar to asbestosis,'2 silicosis of the lung might produce a benign pleural effusion. There are similarities in the inflammatory and exudative tissue response to both ty...

Occupational exposure is an important risk factor for chronic obstructive pulmonary disease (COPD), and silica dust is one of the most important occupational respiratory toxins. Epidemiological and pathological studies suggest that silica dust exposure can lead to COPD, even in the absence of radiological signs of silicosis, and that the association between cumulative silica dust exposure and a...
