Evaluation of the Reflux Symptom Index and the Endolaryngeal Findings Scale after Treatment in Individuals with Laryngopharyngeal Reflux.

 Laryngopharyngeal reflux (LPR) is a prevalent condition in outpatients visiting the otorhinolaryngological clinic, with many controversies regarding its diagnosis and follow-up. Therefore, there is a need for clinical instruments that can diagnose individuals and monitor the results of their treatment.  To evaluate the applicability of the scores translated and adapted to Brazilian Portuguese: Reflux Symptom Index (RSI) and Endolaryngeal Reflux Findings Scale (ERFS), as instruments for post-treatment follow-up of LPR.

Temporal Association Between Respiratory Events and Reflux in Patients With Obstructive Sleep Apnea and Laryngopharyngeal Reflux.

Study Objectives: The aim of the current study was to test the hypothesis that there is a temporal correlation between reflux episodes and respiratory events in patients with laryngopharyngeal reflux and obstructive sleep apnea.

Methods: Adults with clinically diagnosed laryngopharyngeal reflux confirmed by two validated instruments (reflux symptom index ≥ 13 and reflux finding score ≥ 7) and obstructive sleep apnea (OSA) underwent full polysomnography with concomitant and synchronized multichannel intraluminal impedance-pH esophageal monitoring. The apnea-hypopnea and arousal indexes that occurred 15, 30, and 45 minutes before and after each reflux episode were recorded and compared to full-night apnea and hypopnea and arousal index.

Granular cell tumor of the larynx in children: a case report.

The granular cell tumor (GCT) is an uncommon neoplasm, with slow progression, usually benign, that can be found in any organ. The most common region for GCT involvement is in the head and neck. Laryngeal involvement is uncommon and accounts for 6 to 10% of all cases reported.

Laryngeal electromyography in adults with Parkinson's disease and voice complaints.

Objective: To study the laryngeal electromyography (LEMG) pattern in patients with Parkinson's disease (PD) and vocal complaints.

Study Design And Setting: Twenty-six adults with PD and vocal complaints and 26 controls with presbyphonia underwent videolaryngoscopy (VL) and LEMG.

Results: No tremor was found on LEMG of the cricothyroid and thyroarytenoid muscles, even in cases with clinical and VL tremor.
