Although most patients with a malignant pleural effusion are symptomatic, 25% are asymptomatic with an incidental finding of effusion on chest radiography or physical examination.30 Factors that determine potential treatment options for malignant pleural effusions include: Symptoms and patient performance status The most effective treatment of malignant effusions requiring intervention is complete drainage with instillation of a sclerosant to establish pleurodesis and prevent effusion recurrence. Other management options include observation, therapeutic pleural aspiration, thoracoscopy and pleurodesis or indwelling pleural catheter placement. Approximately 20% of patients with pneumonia will develop a pleural effusion.31,32 Pleural infection typically describes a progressive process from ��simple�� self-resolving parapneumonic effusion to ��complicated�� multiloculated [http://en.wikipedia.org/wiki/Oxalosuccinic_acid Oxalosuccinic acid] fibrinopurulent collection with associated clinical/biochemical features of sepsis. Pleural effusions that are small, that is, [http://www.selleckchem.com/products/Vandetanib.html Vandetanib research buy] usually resolve with antibiotics alone.31,33 Pleural fluid should be aspirated if pleural infection is suspected. Frank pus or turbid/cloudy fluid indicates the need for prompt chest drainage of the effusion.31,34�C36 The presence of organisms identified by positive Gram stain also indicates the need for chest tube drainage.31,34�C36 It should be noted, however, that the absence of frank pus on aspiration does not exclude pleural infection and that approximately 40% of pleural fluid cultures are negative despite high clinical suspicion. Numerous studies have demonstrated a need for chest drainage for resolution of non-overtly purulent pleural collections with biochemical evidence of sepsis.31,33�C38 A systematic meta-analysis by Heffner35 concluded pleural fluid pH?[http://www.selleckchem.com/products/Bosutinib.html check details] most powerful indicator to predict the need for chest drainage, and that other pleural fluid parameters (glucose and LDH) did not improve accuracy. The BTS and American College of Chest Physicians support these findings, recommending chest tube drainage for parapneumonic effusions with pleural pH?
