Comparative Study
Comparison of clinical characteristics of chronic cough due to non-acid and acid gastroesophageal reflux.
Little is known about non-acid gastroesophageal reflux-induced chronic cough (GERC). The purpose of the study is to explore the clinical characteristics of non-acid GERC. ⋯ There are some differences in the clinical manifestations between non-acid and acid GERC, but MII-pH is essential to diagnose non-acid GERC.

Randomized Controlled Trial Comparative Study
Electromagnetic navigation-guided TBNA vs conventional TBNA in the diagnosis of mediastinal lymphadenopathy.
Conventional transbronchial needle aspiration (C-TBNA) is a safe method for the diagnosis of hilar and mediastinal lymphadenopathy (MLN). However, diagnostic yield of this technique varies considerably. Electromagnetic navigation bronchoscopy (ENB) is a new technology to increase the diagnostic yield of flexible bronchoscopy for the peripheral lung lesions and MLN. The aim of this prospective study was to compare the diagnostic and sampling success of ENB-guided TBNA (ENB-TBNA) in comparison with C-TBNA while dealing with MLN. ⋯ In this study comparing ENB-TBNA and C-TBNA, the sampling and diagnostic success of ENB-TBNA was found to be superior while dealing with MLN, in all categories studied.
