BACKGROUND The treatment of non-small cell lung cancer (NSCLC) is determined by accurate definition of the stage. If there are no distant metastases, the status of the mediastinal lymph nodes is critical. Although imaging studies can provide some guidance, in many situations invasive staging is necessary. Many different complementary techniques are(More)
Invasive pulmonary aspergillosis (IPA) is a major cause of mortality in patients with stem cell transplants and hematologic malignancies. Timely diagnosis of IPA improves survival but is difficult to make. We evaluated the effectiveness of bronchoalveolar lavage (BAL) galactomannan (GM) in diagnosing IPA in these populations by retrospectively reviewing(More)
The pleural mesothelial cell is an essential cell in maintaining the normal homeostasis of the pleural space and it is also a central component of the pathophysiologic processes affecting the pleural space. In this review, we will review the defense mechanisms of the pleural mesothelium and changes in pleural physiology as a result of inflammatory,(More)
BACKGROUND Optimal performance of bronchoscopy requires patient's comfort, physician's ease of execution, and minimal risk. There is currently a wide variation in the use of topical anesthesia, analgesia, and sedation during bronchoscopy. METHODS A panel of experts was convened by the American College of Chest Physicians Interventional/Chest Diagnostic(More)
Pulmonary nodules and nodular infiltrates occur frequently during treatment of hematologic malignancies and after hematopoietic cell transplantation. In patients not receiving active immunosuppressive therapy, the most likely culprits are primary lung cancer, chronic infectious or inactive granulomata, or even the underlying hematologic disease itself(More)
BACKGROUND Airway complications are among the most challenging problems after lung transplantation. This article describes the use of a new tracheobronchial stent that can be placed and removed easily by flexible bronchoscopy. METHODS A retrospective review was done of 24 consecutive patients requiring tracheobronchial stent placement after lung(More)
RATIONALE Malignant airway obstruction is commonly found in patients with lung cancer and is associated with significant morbidity and mortality. Relieving malignant obstruction may improve symptoms, quality of life, and life expectancy. OBJECTIVES The objective of this study was to analyze our experience with bronchoscopic endobronchial intratumoral(More)
Management of esophago-airway fistulas (EAF) and obstructions often involves therapy with esophageal and/or airway stents. We present a unique approach for the management of EAF and obstructions with simultaneous upper endoscopy and bronchoscopy (two scopes inserted simultaneously through the mouth). The aim is to assess the efficacy and safety of a(More)
