Pleural effusion is a common clinical manifestation with various causes. Current diagnostic and therapeutic methods have exhibited numerous limitations. By involving the analysis of dynamic changes in low molecular weight catabolites, metabolomics has been widely applied in various types of disease and have provided platforms to distinguish many novel biomarkers. However, to the best of our kno...

OBJECTIVE To review our experience of indications, technique, and complications as they relate to video-assisted thoracoscopic surgery (VATS) in the diagnosis and management of intrathoracic diseases. SUBJECTS AND METHODS One hundred and fifty consecutive VATS procedures, which were performed over a 3-year period, were retrospectively evaluated. Indications included recurrent or persistent pr...

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...

Between October 1998 and September 1999, 98 patients with symptomatic exudative lymphocytic pleural effusion were enrolled in our study to evaluated the diagnostic sensitivity of polymerase chain reaction (PCR) assay. The mean age was 53.3 years ranging from 18 to 78 years. There were 61 men and 37 women. Pleural fluid was sent for gram staining, AFB staining, aerobic culture, culture of Mycoba...

introduction: different etiologies of pleural effusion are diagnosed based on serum and plural fluid characteristics. the aim of this study was to assess and compare the serum and pleural fluid protein to lactate dehyrogenase (pr/ldh) ratio in exudative pleural effusions. materials and methods: this study was conducted on 60 patients with exudative pleural effusion including: 20 cases with para...

Consideration of the human epidemiology of diseases arising from exposure to naturally occurring and man-made mineral fibers encompasses the several forms of asbestos (chrysotile, crocidolite, amosite, anthophyllite, tremolite-actinolite), other naturally occurring silicates (talc, sepiolite, erionite, attapulgite, vermiculite, and wollastonite), and man-made mineral fibers (glass continuous fi...

This chapter presents a bibliographic review of asbestos-related diseases. The latest diagnostic, radiological, computed tomography and lung function aspects of benign pleural disease, asbestosis, occupational lung cancer and mesothelioma are discussed.

Background: Blind percutaneous pleural biopsy has traditionally been performed to investigate the etiology of exudative pleural effusion in which the initial thoracocentesis has been non- diagnostic. In view of the increasing use of image-guided and thoracoscopic pleural biopsies, this study examined the role of blind Abrams pleural biopsy in the investigation of the exudative pleural effusion ...
