Change in lung function in never-smokers with nontuberculous mycobacterial lung disease: A retrospective study.

Purpose: Never-smokers account for a large proportion of subjects in general population studies on nontuberculous mycobacteria lung disease (NTM-LD). However, the influence of NTM infection on the lung function of never-smokers has not yet been evaluated. The aim of this study was to determine how NTM-LD impairs the lung function in never-smokers, and whether there are an association between successful NTM-LD treatment in radiologic outcomes and improvement in lung function of never-smokers with NTM-LD or not.

subsp. Lung Disease: Drug Susceptibility Testing in Sputum Culture Negative Conversion.

Background: Among Mycobacterium abscessus complex infections, patients with M. abscessus subsp. abscessus (MAA) lung disease are difficult to treat and no standard therapy has been established.

Clinical Features of Nontuberculous Mycobacterial Pleurisy: A Review of 12 Cases.

Objective The incidence of pulmonary nontuberculous mycobacterial (NTM) infections has increased in recent decades. Nevertheless, NTM pleurisy is still a rare disease. The objective of the present study was to elucidate the clinical features and outcomes of NTM pleurisy.

Predictive Factors of Nivolumab-induced Hypothyroidism in Patients with Non-small Cell Lung Cancer.

Background/aim: Although immune checkpoint inhibitors play an important role in the therapy of lung cancer, they are associated with various immune-related adverse events and predictive factors of them are unclear. In this study, we investigated predictive factors of nivolumab-induced hypothyroidism which is one of the adverse events in patients with lung cancer.

Patients And Methods: Patients with non-small-cell lung cancer who were administered nivolumab at our hospital between December 2015 and May 2016 were retrospectively enrolled.

Combination of virtual bronchoscopic navigation, endobronchial ultrasound, and rapid on-site evaluation for diagnosing small peripheral pulmonary lesions: a prospective phase II study.

Background: The diagnostic yield of peripheral pulmonary lesions (PPLs) by flexible bronchoscopy (FB) is still insufficient. To improve the diagnostic yield of bronchoscopy, several techniques such as endobronchial ultrasound (EBUS), virtual bronchoscopic navigation (VBN), and rapid on-site evaluation (ROSE) have been examined. The primary purpose of the present study was to evaluate the usefulness of combining EBUS, VBN, and ROSE for diagnosing small PPLs.

A Cryptogenic Case of Fulminant Fibrosing Organizing Pneumonia.

Cryptogenic organizing pneumonia (COP) generally responds well to corticosteroids with a favorable outcome. Rare cases of organizing pneumonia are rapidly progressive. Yousem et al.

Systemic Air Embolism Following Diagnostic Bronchoscopy.

A 51-year-old man was admitted to have a nodule evaluated using chest computed tomography (CT). Shortly after curetting and transbronchial biopsies via bronchoscopy, hypotension, bradycardia, unconsciousness, and left hemiplegia appeared and resolved within one hour. Head CT showed cerebral air embolism.

[CLINICAL STUDY OF 29 CASES OF ENDOBRONCHIAL TUBERCULOSIS].

[Background] Endobronchial tuberculosis (EBTB) is defined as a tuberculosis infection of the tracheobronchial tree and is often misdiagnosed as bronchial asthma or bron- chitis owing to a lack of typical imaging findings. [Aim] The aim of this study was to elucidate the clinical characteristics of EBTB. [Method] We retrospectively studied EBTB patients hos- pitalized at the National Hospital Organization Kinki-chuo Chest Medical Center (Sakai City, Japan) between January 2005 and April 2014.

Intravascular synovial sarcoma of the pulmonary artery with massive pleural effusion: report of a case with a favorable response to Ifosfamide chemotherapy and palliative radiation therapy.

Synovial sarcoma (SS) commonly arises in the para-articular soft tissue; however, very few cases of intravascular SS have so far been reported. We herein describe a case of pulmonary artery SS with massive pleural effusion. A biopsy of the pleural lesions showed uniform short spindle cell proliferation, while the SYT-SSX fusion gene, which is preceded by chromosomal translocation t(X;18)(p11;q11), was detected using reverse transcription-polymerase chain reaction.
