BACKGROUND New biomarkers are needed to detect pleural mesothelioma at an earlier stage and to individualize treatment strategies. We investigated whether fibulin-3 in plasma and pleural effusions could meet sensitivity and specificity criteria for a robust biomarker. METHODS We measured fibulin-3 levels in plasma (from 92 patients with mesothelioma, 136 asbestos-exposed persons without cance...
Transudative pleural effusions develop because the distribution of hydrostatic and oncotic pressure across the pleura is altered, so that the rate of pleural fluid formation exceeds that of its reabsorption. They are characterized by a low cell and protein content. Congestive heart failure is the most common cause of transudative effusion. The fluid that accumulates in a hepatic hydrothorax, ur...
In a retrospective study of 100 patients with pleural effusion the final diagnosis was tuberculosis in 49, malignancy in 43, malignancy with tuberculosis, bacterial infection, hydrothorax with cirrhosis, reaction to pneumothorax in one each, and unknown in 4. Most of the effusions analysed were exudates (94%). Pleural biopsy was diagnostic in 46% of tuberculous effusions (13/28) and 67% of mali...
Neoplastic diseases account for approximately 13% of the annual incidence of pleural effusions, and 75% of these effusions are secondary to malignancies of the lungs and breast or lymphoma. The most common pathogenic mechanisms that produce malignant pleural effusions (MPE) are (1) pleural metastasis resulting in increased membrane permeability beyond the capacity of lymphatic drainage, (2) met...
Recurrent and symptomatic pleural effusions are common in patients with malignancy. Up to 25% of patients with lung cancer and 50% of patients with breast cancer will develop a pleural effusion. Overall, mesothelioma, and breast and lung cancer, account for the majority of malignant pleural effusions [1]. A minority of effusions remain asymptomatic and few cancers involving the pleura can be cu...
Pleural effusions, seen in isolation or in association with a number of pulmonary and systemic diseases, are common problems in both the in-patient and out-patient setting. The incidence of pleural effusion in the general population is hard to estimate. Reports suggest an incidence of 0.3% in the general population, with as many as 800,000 cases annually. Pleural effusions frequently complicate...

We review the literature on the use of point-of-care ultrasound to evaluate and manage pleural effusions. Point-of-care ultrasound is more sensitive than physical exam and chest radiography to detect pleural effusions, and avoids many negative aspects of computerized tomography. Additionally, point-of-care ultrasound can assess pleural fluid volume and character, revealing possible underlying p...
