In the United States, approximately one million patients each year develop a pleural effusion. Pleural effusions have classically been divided into transudative and exudative pleural effusions. A transudative pleural effusion occurs when the systemic factors influencing pleural fluid formation and reabsorption are altered so that pleural fluid accumulates; an exudative pleural effusion occurs w...

background: pleurisy is a common extra pulmonary complication of tuberculosis, but current methods for diagnosing it are fairly crude. here we product a meta-analysis for the available evidence on the ability of tumor necrosis factor-? (tnf-?) in pleural fluid to serve as a diagnostic marker of tuberculous pleurisy (tp). materials and methods: we searched the pubmed, embase, and google scholar ...

CT chest performed to investigate dyspnea and malaise in an 83 year old man demonstrated bilateral circumferential pleural thickening highly suspicious for pleural mesothelioma or metastatic pleural malignancy. Histopathology of a subsequent pleural biopsy returned a diagnosis of pleural amyloid. This case identifies pleural amyloid as a rare differential consideration for diffuse pleural thick...

Pleural fluid characteristics of 26 patients diagnosed with malignant mesothelioma over an 18-year period were reviewed and compared with those of patients with effusions due to other malignancies. Survival from time of initial thoracentesis was directly correlated with pleural pH and decreased pleural fluid/serum glucose ratios but was not related to protein or LDH concentration. Decreased ple...

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. ...

The most common causes of chylothorax are neoplasmparticularly lymphoma-and trauma. The usual presenting symptom is dyspnea resulting from the accumulation of pleural fluid. The diagnosis of chylothorax is established by measuring triglyceride levels in the pleural fluid; a triglyceride level of greater than 110 mg/dL supports the diagnosis. The initial approach to management involves chest tub...

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...
