13. Exposição ocupacional a poeiras em marmorarias: tamanhos de partículas caracteristicos
The main occupational hazards found in workplaces include dust exposure, facilitating the increase of respiratory diseases, of which silicosis is the most important. Due to the importance and gravity of the occupational exposure to dust and to the high number of workers exposed, the aim of this paper was to study the characteristics of this exposure in the o

14. Pneumoconioses : casuistica de 25 anos do atendimento ambulatorial do Hospital das Clinicas da Unicamp, de 1978 a 2003, em Campinas (SP)
Os dados brasileiros sobre a epidemiologia das pneumoconioses são limitados; ainda não dispomos de informações suficientes para o dimensionamento desse problema em nosso país. A consolidação dos dados, que permitem avaliar os agravos à saúde e seus fatores intervenientes, é uma ferramenta fundamental para seu controle e a avaliação e para a elabo

15. Silicosis associated with systemic lupus erythematosus
The hypothesis that exposure to silica might be associated with a wide range of autoimmune diseases including SLE (Systemic Lupus Erythematosus) has been discussed over the last decade, but only few cases of silicosis and SLE were described in the literature. We report the case of a male patient in his fifth decade of life, with previous exposure to silica,

16. Interstitial granulomatous pulmonary diseases: a diagnostic approach for the general pathologist
Some kinds of interstitial pneumonia present a histopathological pattern dominated by sarcoid - necrotizing or non-necrotizing - granulomas, which can be divided into two main groups: infectious and non-infectious. The infectious causes include tuberculosis, histoplasmosis, fungi in general, paracoccidioidomycosis, ascaridiasis, echinococcosis and dirophilar

17. Prevalencia da silicose entre os trabalhadores das industrias ceramicas do municipio de Pedreira-SP
The present study was conducted in the area of Pedreira - SP, Brazil, where ceramic activity is very intense, leading to the assumption that the majority of the working population is exposed to dust containing silica. The author believed it convenient to carry out this research with the following purposes. To study the prevalence of pulmonary silicosis among

18. A função de monocitos em individuos expostos a silica
The inhalation of silica partic1es leads to silicosis and the development of a chronic inflammatory disease involving granuloma formation and pulmonary fibrosis. In this work, we have evalueted the chemotaxis, CRI and CRJ mediated phagocytosis, and superoxide anion production of monocytes from 21 individuaIs who had experienced chronic exposure to silica and

19. Association of silicosis, lung dysfunction, and emphysema in gold miners.
BACKGROUND--In an earlier study of gold miners men with silicosis were found to have abnormal lung function, including airflow obstruction and reduced diffusing capacity. In a follow up study a sample of these men was examined by computed tomography to determine whether emphysema accounted for these abnormalities, which are associated with silicosis in this

20. The relation between fibrosis of hilar lymph glands and the development of parenchymal silicosis.
The necropsy findings on the cardiorespiratory organs of 849 South African gold miners were analysed to test the hypothesis that fibrosis of the hilar lymph glands predisposes to the development of parenchymal silicotic nodules. Four hundred and eighty three cases had fibrosed glands, 34% of which also had parenchymal silicosis. By comparison, of 238 cases w

21. Role of infective, immunological, and chronic irritative factors in the development of silicosis.
The effect of infective, immunological, and irritative factors on the onset and development of silicosis after intratracheal inoculation with 50 mg of tridymite was investigated on 220 specific pathogen free (SPF) female Sprague-Dawley rats. Even after 12 months the rats, always kept in SPF conditions after intratracheal injection of the dust, showed mainly

22. Retroperitoneal silicosis mimicking pancreatic carcinoma in an Alpine miner with chronic lung silicosis.
A miner, known to have had lung silicosis for 30 years, was investigated for abdominal pain. A retroperitoneal mass was found, in which histological examination showed an inflammatory reaction to silica.

23. SILICOSIS FROM QUARRYING AND WORKING OF GRANITE
Previous knowledge of silicosis in the Swedish granite industry suggested that the disease was neither common nor severe. In recent years, however, changes in working methods have involved a considerably increased formation of dust, and it was considered likely that the risk of contracting silicosis was increased. Reports from other countries supported this

24. Silicosis presenting as bilateral hilar lymphadenopathy.
Classical radiographic features of patients presenting with silicosis are diffuse interstitial shadowing with subsequent enlargement of hilar nodes, sometimes with "eggshell" calcification. Five case histories are described of workers who were exposed to silica and presented initially with bilateral hilar lymphadenopathy without radiographic evidence of inte
