Tracheal bronchus is an abnormal bronchus that comes directly off the lateral wall of the trachea (ie, above the main carina) and supplies ventilation to the upper lobe. A new nomenclature and classification system has been developed for tracheal bronchus. The purpose of this study was to evaluate the anatomic and bronchoscopic features of tracheal bronchus subtypes on the basis of the new nomenclature and classification system. ⋯ Displaced preeparterial tracheal bronchus was the most common subtype of tracheal bronchus. Furthermore, in all cases, tracheal bronchus was located on the right side of the trachea. Both flexible bronchoscopy and computed tomography of the chest were crucial for its diagnosis.

Electromagnetic navigational bronchoscopy: an effective and safe approach to diagnose peripheral lung lesions unreachable by conventional bronchoscopy in high-risk patients.
The purpose of this study was to investigate the diagnostic yield and safety of electromagnetic navigation bronchoscopy (ENB) on peripheral lung lesions deemed otherwise unreachable using conventional bronchoscopy in high-risk patients. ⋯ ENB is an effective, minimally invasive method for the diagnosis of pulmonary nodules previously deemed unreachable by conventional bronchoscopy in high-risk patients and harbors a low complication rate.

Pleuroparenchymal fibroelastosis presenting as a hypermetabolic lung nodule.
Idiopathic pleuroparenchymal fibroelastosis is a rare, benign entity consisting of fibrotic thickening of the pleura and subpleural parenchyma due to elastic fiber proliferation. We present an elderly, male smoker with chronic obstructive airway disease and bilateral apical pleuropulmonary fibrotic changes. ⋯ Surgical resection of the nodule for presumptive malignancy showed fibroelastosis with reactive lymph node hyperplasia. To our knowledge, this is the first reported case of nodular parenchymal fibroelastosis, with increased uptake as shown on a PET scan.

Virtual reality (VR) bronchoscopy simulators have been available for more than a decade, and have been recognized as an important aid in bronchoscopy training. The existing literature has only examined the role of VR simulators in diagnostic bronchoscopy. The aim of this study was to find out whether the simulations of both diagnostic bronchoscopies and more advanced procedures were realistic, and whether clinical experience in bronchoscopy was associated with better and faster performance of basic pulmonary procedures in the simulator. ⋯ Simulation of performing the procedures was significantly less realistic than the simulation of the anatomy and the scope. It was impossible to use the simulator metrics to assess the quality of the biopsies. Despite these deficiencies, clinicians recommend the use of VR simulators in the teaching of pulmonary procedures.

Fospropofol Disodium for Sedation in Elderly Patients Undergoing Flexible Bronchoscopy.
Fospropofol disodium is a water-soluble prodrug of propofol. A subset analysis was undertaken of elderly patients (≥65 y) undergoing flexible bronchoscopy, who were part of a larger multicenter, randomized, double-blind study. ⋯ Fospropofol provided safe and effective sedation, rapid time to fully alert, and high satisfaction in this elderly subset undergoing flexible bronchoscopy, which was comparable with outcomes in younger patients.
