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...

introduction: medical thoracoscopy is a minimally invasive procedure for diagnosing and treating pleural diseases. despite its proven role in diagnostic and therapeutic purposes, it is infrequently used, which could be because of cost of equipment and lack of training. we analyzed our initial 3 years record of thoracoscopy at himalayan institute of medical sciences, a tertiary care center in hi...

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 ...

We studied interleukin 1 (IL-1) activity of pleural fluid macrophages and peripheral blood monocytes obtained from ten patients with tuberculous pleurisy and ten patients with malignant pleurisy, using purified protein derivative (PPD) as a stimulating agent. Tuberculous pleural fluid macrophages and peripheral blood monocytes tended to produce higher IL-1 activity than malignant pleural fluid ...

Although infectious, inflammatory and neoplastic diseases frequently involve the pleural space and walls, little is known about the immunological and molecular mechanisms underlying pleural disorders. This article provides an overview of recent insights into immunobiological processes likely to play a role in the pathogenesis of pleural disorders. Pleural involvement in certain diseases is asso...

UNLABELLED Malignant pleural effusion in patients with cancers or malignant pleural mesothelioma may often appear at the late stage of disease and significantly affect the patients' life quality and survival. However, there is still no very effective treatment to control malignant pleural effusion. Here we report that malignant pleural effusion in one patient was completely relieved for 15 mont...

Malignant mesothelioma is a fatal asbestos-associated malignancy originating from the lining cells (mesothelium) of the pleural and peritoneal cavities, as well as the pericardium and the tunica vaginalis. The exact prevalence is unknown but it is estimated that mesotheliomas represent less than 1% of all cancers. Its incidence is increasing, with an expected peak in the next 10-20 years. Pleur...

BACKGROUND Each year in the United States an estimated 1.5 million people develop pleural effusions and approximately 178,000 thoracenteses (12%) are performed. While it has been established that malignant effusions are associated with increased mortality, the association between mortality and all-cause pleural effusions in a medical population has not been previously evaluated. Our objective w...

In cases of pleural lesion, tissue samples can be obtained through thoracoscopy or closed needle biopsy for histopathological analysis. Cutting needle biopsy is a relatively recent addition to these techniques. The aim of this study was to evaluate the diagnostic accuracy and safety of computed tomography-guided cutting needle pleural biopsy (CT-CNPB), as well as the associated complications, i...
