BACKGROUND Sandblasting of jeans in small Turkish workshops has recently been recognized as a cause of silicosis. CASE SERIES Between August 2004 and March 2006, we admitted 16 young men with a history of working in small workplaces producing sandblasted jeans. Of these, 14 presented with respiratory symptoms and the remaining two through awareness of their work colleagues. In the first two c...

Silicosis is one of the most serious occupational diseases in China and dates back to centuries ago. In this study, we successfully established a rat model of silicosis by intratracheal silica injection for 28 days and determined hydroxyproline levels to evaluate collagen metabolism in lung homogenates. Oxidative stress status was evaluated by detecting catalase and glutathione peroxidase activ...

background: silicosis is considered an oxidative stress related disease that can lead to the development of lung cancer. in this study, our purpose was to analysis of volatile organic compounds (vocs) in the exhaled breath of workers exposed to silica containing dust and compare peak area of these compounds with silicosis patients and healthy volunteers (smokers and nonsmokers) groups. methods ...

OBJECTIVES To evaluate the association between silica, silicosis and lung cancer, the mortality of 724 patients with silicosis, first diagnosed by standard chest x ray film between 1964 and 1970, has been analysed by a cohort study extended to 31 December 1997. METHODS Smoking and detailed occupational histories were available for each member of the cohort as well as the estimated lifetime ex...

BACKGROUND Silicosis is a complex lung disease for which no successful treatment is available and therefore lung transplantation is a potential alternative. Tumor necrosis factor alpha (TNFalpha) plays a central role in the pathogenesis of silicosis. TNFalpha signaling is mediated by the transcription factor, Nuclear Factor (NF)-kappaB, which regulates genes controlling several physiological pr...

Chronic inhalation of crystalline silica and silicates may lead to severe lung disease in humans, termed silicosis. The disease is an occupational health concern in miners and related professions worldwide. Silicosis is also a strong risk factor for tuberculosis in humans. Due to its subterranean lifestyle, the European badger (Meles meles) is continuously exposed to environmental dust, while t...

Silicosis, an interstitial lung disease caused by the inhalation of crystalline silica powder, despite being one of the oldest occupational diseases, continues being a cause of morbidity and mortality all over the world. The World Health Organisation and the International Labour Organisation (OMS/ILO), aware of the current problem, have designed the World Programme for the Elimination of Silico...

Silica and silicate mineral dust inhalation can cause a variety of histopathological changes in the lungs and pleura. These include pulmonary silicotic nodules, interstitial infiltrate, fibrosis, and pleural thickening. Pleural effusion is an extremely rare presentation of silicosis. To our best knowledge, there have been only 2 cases of silicosis with pleural effusion reported in medical liter...

Four men who mined barytes in Scotland and who developed pneumoconiosis are described. Three developed progressive massive fibrosis, from which two died; and one developed a nodular simple pneumoconiosis after leaving the industry. The radiological and pathological features of the men's lungs were those of silicosis and high proportions of quartz were found in two of them post mortem. The quart...
