Pleural Effusion
September 15, 2007

Congestive heart failure and cirrhosis are the most common causes of transudative pleural effusions, while pneumonia and malignancy are responsible for the majority of exudative effusions. Plain chest films are valuable in confirming the presence of an effusion, providing clues to the cause, and directing the method of pleural fluid sampling. Thoracentesis is safe and simple, and it is diagnostic in about 75% of cases. Pleural biopsy is indicated for unexplained exudative effusions, most of which are found to result from malignancy or tuberculosis. Medical thoracoscopy, if available, is the procedure of choice for patients with these effusions. Thoracoscopy permits visually directed pleural biopsies and allows for therapeutic intervention at the time of diagnosis, obviating the need for subsequent invasive procedures.

How to quickly zero in on the diagnosis Hemoptysis: A review of causes, evaluation, and treatment key words: Hemoptysis, Bronchoscopy, Embolization
April 01, 2007

abstract: Hemoptysis has many causes, including bronchiectasis, lung cancer, and bronchitis. The initial goals of the history and physical examination are to differentiate hemoptysis from epistaxis and hematemesis and then to establish its severity. A variety of signs and symptoms may suggest the underlying cause. For example, hematuria suggests vasculitis or an immunologically mediated disease, such as Wegener granulomatosis or systemic lupus erythematosus. The workup includes chest radiography and measurement of hemoglobin and hematocrit levels, platelet count, international normalized ratio, activated partial thromboplastin time, and creatinine level. Chest CT scanning often identifies sources of bleeding that are not apparent on radiographs and sometimes can be used in conjunction with bronchoscopy. Patients with massive hemoptysis should be hospitalized for rapid evaluation and intervention; treatment may include interventional bronchoscopy, angiography, or embolization.
