BACKGROUND Correctly staging lung cancer is important because the treatment options and prognosis differ significantly by stage. Several noninvasive imaging studies and invasive tests are available. Understanding the accuracy, advantages, and disadvantages of the available methods for staging non-small cell lung cancer is critical to decision-making. (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)
Glomus tumors are unusual and generally benign neoplasms mainly found in subungeal areas. We describe a case of concomitant subcutaneous and tracheal glomus tumor that underwent successful endoscopic resection. A 48-year old male with a left forearm subcutaneous mass presented with hemoptysis. A chest CT scan demonstrated a polypoid tracheal lesion. He(More)
3' phosphorothioate modified sense or antisense oligonucleotides to oxytocin transcripts were used for in vivo targeting of oxytocin (OT) neurons in the rat hypothalamus. Intracerebroventricular injections of antisense probe resulted in a loss of systemic OT. However, abundant immunoreactive OT as well as oxytocin mRNA hybridization signal was visualized in(More)
Introduction. Endobronchial ultrasound (EBUS) is a procedure that provides access to the mediastinal staging; however, EBUS cannot be used to stage all of the nodes in the mediastinum. In these cases, endoscopic ultrasound (EUS) is used for complete staging. Objective. To provide a synthesis of the evidence on the diagnostic performance of EBUS + EUS in(More)
OBJECTIVES High preoperative risk precludes decortication and other surgical interventions in some patients with chronic empyema. We manage such patients by converting the chest tube into an "empyema tube," cutting the tube near the skin and securing the end with a sterile clip to allow for open pleural drainage. The patient is followed serially, and the(More)
