Objective: To investigate worldwide practices of otolaryngologists in the management of laryngopharyngeal reflux (LPR).
Methods: An online survey was sent on the management of LPR to members of many otolaryngological societies. The following aspects were evaluated: LPR definition, prevalence, clinical presentation, diagnosis, and treatment.
Results: A total of 824 otolaryngologists participated, spread over 65 countries. The symptoms most usually attributed to LPR are cough after lying down/meal, throat clearing and globus sensation while LPR-related findings are arytenoid erythema and posterior commissure hypertrophy. Irrespective to geography, otolaryngologists indicate lack of familiarity with impedance pH monitoring, which they attribute to lack of knowledge in result interpretation. The most common therapeutic regimens significantly vary between world regions, with a higher use of H2 blocker in North America and a lower use of alginate in South America. The duration of treatment also significantly varies between different regions, with West Asia/Africa and East Asia/Oceania otolaryngologists prescribing medication for a shorter period than the others. Only 21.1% of respondents are aware about the existence of nonacid LPR. Overall, only 43.2% of otolaryngologists believe themselves sufficiently knowledgeable about LPR.
Conclusions: LPR knowledge and management significantly vary across the world. International guidelines on LPR definition, diagnosis, and treatment are needed to improve knowledge and management around the world.

The relationship between symptoms of laryngopharyngeal reflux (LPR) and objective reflux measurements obtained through multichannel intraluminal impedance-pH (MII-pH) monitoring remains unclear. The aim of this study was to investigate the relationship between LPR symptoms and objective reflux episodes and possible associations between fibreoptic ENT findings, eosinophil counts, and serum IgE levels with reflux episodes detected by MII-pH. In this prospective study, MII-pH monitoring, fiberoptic laryngoscopy, nasal swabs for eosinophils, total serum IgE levels, and symptom assessment (Reflux Symptom Index, RSI) were performed in all children with suspected LPR.

Objective: Our aim is to determine the comparative effectiveness of unimodality organ preservation surgery versus radiotherapy on oncological and functional outcomes in patients with early hypopharyngeal cancer.
Introduction: Early hypopharyngeal cancer is difficult to detect and therefore rarely diagnosed, as patients are often asymptomatic. Radiotherapy is considered the main treatment, although this modality has been compared to the previously used open surgical approach, which may not reflect current surgical options.
Positive effect of erythromycin on ineffective oesophageal motility in laryngopharyngeal reflux patients: Room for a novel treatment?

Introduction: Laryngopharyngeal reflux (LPR) management guidelines are currently derived from the management of gastroesophageal reflux disease (GORD) which has been shown to be poorly effective in controlling symptoms for these patients. Erythromycin is a macrolide antibiotic that has been used extensively as a prokinetic agent for the gastrointestinal tract. The management of LPR with prokinetics is a novel therapy being investigated with regard to its effectiveness.

Cough is one of the most common reasons patients seek medical care in the outpatient setting. Chronic cough (CC) in adults is defined as a cough lasting more than 8 weeks, with a global prevalence of approximately 10%. CC significantly impairs quality of life, affecting physical, social, and psychological well-being.
