The objective of the present study was to investigate the presence of interleukin (IL)-27 in pleural effusions and to evaluate the diagnostic significance of pleural IL-27. The concentrations of IL-27 were determined in pleural fluids and sera from 68 patients with tuberculous pleural effusion, 63 malignant pleural effusion, 22 infectious pleural effusion, and 21 transudative pleural effusion. ...

background and objectives:infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. the aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (pe). materials and methods: in this cross sectional study, 1210 samples with exudative features were cultured for poss...

Background: Pleural effusion is a common condition in pulmonary medicine. Determining the cause of the pleural effusion is a difficult task. The distinction between an exudate and a transudate is the first and the most important step in the differential diagnosis of a pleural effusion. Light’s criterion have been previously used for classifying pleural effusion. There are multiple other biochem...

Chylous pleural effusion is characterized by milky-appearing fluid with elevated triglyceride content and presence of chylomicrons in the pleural space. Even though patients with lymphoma sometimes present with malignant pleural effusion, chylous effusion is rarely encountered as a presenting feature in such patients. We present a 47-year-old woman diagnosed as follicular lymphoma who presented...

Open and Video-Assisted Thoracoscopycal pleural decortications are proved and effective surgical procedure in the surgical treatment of pleural empyema in the fibrinopurulent stage. Early referral to surgery gives a better chance of success in VATS pleural decortications than open decortications. Pleural morphology, biochemistry and biology can also affect the outcome of the surgical treatment ...

BACKGROUND Malignant pleural mesothelioma (MPM) is a rare malignant neoplasm of the pleura that typically affects individuals occupationally exposed to asbestos through a variety of industries. MPM presents with several CT features similar to more common pleural diseases such as metastatic pleural malignancy. OBJECTIVES The aim of this study is to differentiate malignant pleural mesothelioma ...

This study presents the differential diagnosis of metastatic tumors of the pleura vs. primary pleural malignancies in a male patient whose diagnosis was multiple myeloma with pleural involvement and confirmed by bone marrow aspiration and pleural biopsy. Computed tomography (CT) manifestations of this case were retrospectively analyzed, and compared with those of primary pleural malignancies. T...

While pleural effusion in multiple myeloma is relatively infrequent, myelomatous pleural effusion is extremely rare. We experienced a 61-year-old woman with IgD-lambda multiple myeloma and pleural effusion. The diagnosis was made originally by pleural biopsy, pleural fluid cytology and immunoelectropheresis of pleural fluid. Transient improvement of the pleural effusion was observed after admin...

Minimally invasive investigations, such as pleural fluid cytological assessment and closed percutaneous pleural biopsy, are often performed first in the investigation of suspected malignant pleural effusions. Malignant pleural effusions can be diagnosed with pleural fluid cytology alone in most cases; however, closed pleural biopsy is performed to increase the diagnostic yield when pleural flui...

The pleural space separating the lung and chest wall of mammals contains a small amount of liquid that lubricates the pleural surfaces during breathing. Recent studies have pointed to a conceptual understanding of the pleural space that is different from the one advocated some 30 years ago in this journal. The fundamental concept is that pleural surface pressure, the result of the opposing reco...
