Characteristics of Laryngopharyngeal Reflux in the Chinese Nurse Population.

Objectives: To investigate the prevalence of laryngopharyngeal reflux (LPR) and knowledge of LPR in the Chinese nurse population.

Method: From October 2021 through December 2021, participants were recruited from the PLA General Hospital's Sixth Medical Center. All included participants completed the Reflux Symptom Index (RSI), and LPR was defined as RSI > 13.

Does hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring for the diagnosis of laryngopharyngeal reflux have to be 24 h?

Purpose: To investigate the diagnostic value of combined multi-timepoint salivary pepsin testing (MTPSPT) and hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH) for laryngopharyngeal reflux (LPR) and whether an appropriate reduction in the duration of HEMII-pH would affect the accuracy of diagnosis of LPR.

Methods: Recruited patients were studied with both MTPSPT and HEMII-pH. The diagnosis of LPR was based on the occurrence of > 1 reflux event and/or positive results on any of the MTPSPT.

Thyroarytenoid botulinum toxin injection for refractory laryngeal contact granuloma.

Background: Although there are many treatments for laryngeal contact granuloma (LCG), some patients still fail treatment. Botulinum toxin A injection vocal cords may be a salvage therapy.

Objectives: To study the efficacy of thyroarytenoid botulinum toxin A injection for the treatment of refractory LCG.

Multitime point pepsin testing can double the rate of the diagnosis of laryngopharyngeal reflux.

Objective: To study the value of multitime point salivary pepsin testing (MTPSPT) for the diagnosis of laryngopharyngeal reflux (LPR).

Study Design: Prospective noncontrolled.

Methods: For patients who met the enrollment criteria, the reflux symptom index (RSI) and reflux finding score (RFS) were calculated and salivary pepsin testing was performed.
