BACKGROUND Hypercapnic respiratory failure in patients with COPD frequently requires mechanical ventilatory support. Extracorporeal CO2 removal (ECCO2R) techniques have not been systematically evaluated in these patients. METHODS This is a pilot study of a novel ECCO2R device that utilizes a single venous catheter with high CO2 removal rates at low blood(More)
BACKGROUND Endobronchial valves that allow air to escape from a pulmonary lobe but not enter it can induce a reduction in lobar volume that may thereby improve lung function and exercise tolerance in patients with pulmonary hyperinflation related to advanced emphysema. METHODS We compared the safety and efficacy of endobronchial-valve therapy in patients(More)
INTRODUCTION Activating somatic mutations of the tyrosine kinase domain of epidermal growth factor receptor (EGFR) have recently been characterized in a subset of patients with advanced non-small cell lung cancer (NSCLC). Patients harboring these mutations in their tumors show excellent response to EGFR tyrosine kinase inhibitors (EGFR-TKIs). The EGFR-TKI(More)
RATIONALE Endobronchial ultrasound (EBUS) and electromagnetic navigation bronchoscopy (ENB) have increased the diagnostic yield of bronchoscopic diagnosis of peripheral lung lesions. However, the role of combining these modalities to overcome each individual technique's limitations and, consequently, to further increase the diagnostic yield remains(More)
INTRODUCTION AND METHODS We investigated the diagnostic and prognostic value of soluble mesothelin-related proteins (SMRP) in sera from patients with newly diagnosed malignant pleural mesothelioma (MPM) (n = 100), MPM patients at tumor relapse (n = 29), primary lung cancer (n = 139), and benign asbestosis (n = 75) using Mesomark--enzyme-linked immunosorbent(More)
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can sample enlarged mediastinal lymph nodes in patients with nonsmall cell lung cancer (NSCLC). To date, EBUS-TBNA has only been used to sample nodes visible on computed tomography (CT). The aim of the present study was to determine the accuracy of EBUS-TBNA in sampling nodes <or=1(More)
A diagnosis of sarcoidosis should be substantiated by pathological means in order to thoroughly exclude other diseases. The role of real-time endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of sarcoidosis has not been reported. The purpose of the present study is to evaluate the diagnostic yield of EBUS-TBNA in(More)
A tissue diagnosis of mediastinal nodes is frequently needed for accurate lung cancer staging as well as the assessment of mediastinal masses. Transbronchial needle aspiration (TBNA) is a safe procedure that is performed during routine bronchoscopy. Provided mediastinal metastases are confirmed, TBNA has a high impact on patient management. Unfortunately,(More)
BACKGROUND For mediastinal lymph nodes, biopsies must often be performed to accurately stage lung cancer. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) allows real-time guidance in sampling paratracheal, subcarinal, and hilar lymph nodes, and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) can sample mediastinal(More)
OBJECTIVE To assess the prevalence and characteristics of airway involvement in relapsing polychondritis (RP). METHODS Retrospective chart review and data analysis of RP patients seen in the Rheumatology Clinic and the Complex Airway Center at Beth Israel Deaconess Medical Center from January 2004 through February 2008. RESULTS RP was diagnosed in 145(More)
