Two different repair mechanisms of mesenchymal stem cells (MSCs) are suggested to participate in the repair of acute lung injury (ALI): (i) Cell engraftment mechanism, (ii) Paracrine/endocrine mechanism. However, the exact roles they play in the repair remain unclear. The aim of the study was to evaluate the role of paracrine/endocrine mechanism using a novel intrapleural delivery method of MSC...

Different procedures are performed to decrease this pain which is associated with significant physiologic, mental and pathologic complications. Each of these procedures has its own advantage and disadvantages. In many centers...

OBJECTIVE A prospective randomized study was conducted in order to analyze the role of fibrinolytics in the treatment of complicated parapneumonic effusion. METHODS From 2001 to 2004, 127 consecutive patients were managed for thoracic empyema. In all cases the cause was bacterial pneumonia. Seventy patients were managed with sole tube thoracostomy (group A) and 57 with combination of tube tho...

BACKGROUND The role of drainage, intrapleural fibrinolytics, and/or surgery in the management of thoracic empyema is controversial. OBJECTIVES We aimed to investigate the operational practice of empyema management at our hospital. METHODS Between January 2001 and December 2008, all patients with thoracic empyema were retrieved. After exclusion of patients with malignant effusion, traumatic ...

A parapneumonic effusion is the collection of exudative fluid in the pleural space associated with a concurrent pulmonary infection. Parapneumonic effusions account for approximately one-third of all effusions, and about 40% of patients with pneumonia develop a concomitant effusion. Patients with pneumonia who develop an effusion have an increased risk of morbidity and mortality. Some of the ex...
