To assess mortality rate among workers occupationally exposed to asbestos, cohort studies were carried out in two asbestos cement plants operating since the 1960s. Asbestos cement sheets for roofing and siding have been manufactured there, using mostly chrisotile, and since 1985 also crocidolite for pressure pipes. In all, the cohort comprised 3,220 workers, including 2,616 male workers. Subjec...

Most pleural neoplasms are metastatic in origin. Primary tumours of the pleura are rare and categorized as diffuse or localized. Diffuse or malignant mesothelioma is more common, related to asbestos exposure, and associated with a poor prognosis. Localized or solitary fibrous tumour (SFT), of the pleura is a less common neoplasm of controversial histogenesis and is unrelated to asbestos exposur...

objective(s) this study planned to assess the value of pcr is6110 assay in tissue specimens of needle pleural biopsy in patients suspicious to pleural tuberculosis. materials and methods sixty eight patients with lymphocytic exudative pleural effusion underwent pleural biopsy. tissue samples were sent for pathologic examination and pcr is6110 assay. the results of pcr reported as positive/ nega...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...

STUDY OBJECTIVES In patients with disseminated neoplastic disease, recurrent pleural effusion is frequently observed. The purpose of this study was to determine the long-term efficacy and safety of pleurodesis by thoracoscopic talc poudrage (TTP) in malignant pleural effusions (MPEs). METHODS We report a consecutive series of 102 patients (45 women, 57 men; 20 to 83 years of age) who underwen...

The burden of pleural diseases has substantially increased in the past decade because of a rise in the incidence of pleural space infections and pleural malignancies in a patient population that is older and more immunocompromised and has more comorbidities. This complexity increasingly requires minimally invasive diagnostic options and tailored management. Implications for patients are such th...

BACKGROUND AND OBJECTIVE: Video-assisted thoracoscopic surgery is preferred over conventional methods, such as pleural biopsy, in the diagnosis and treatment of patients with pleural effusion. Considering that Imam Khomeini Hospital is facing a large volume of patients with pleural effusion of unknown origin referred from other centers, the present study was conducted to investigate the role of...

Background: Malignant pleural effusion is common in patients with advanced malignant tumor. The aim of this study is to analyze the characteristics of pleural metastasis of renal clear cell carcinoma, pleural effusion under medical thoracoscopy and the diagnostic value of interventional thoracoscopy-guided biopsy, and to improve the understanding of pleural metastasis of renal clear cell carcin...
