Laryngopharyngeal reflux

Introduction  Patients with chronic rhinitis suffer from postnasal drip (PND) but this symptom is not well addressed. Nasal endoscopy may aid in identifying PND. Well described endoscopic features of PND are presence of secretions in the posterior nasal cavity, diffuse erythema, and hemorrhagic spots in the nasopharynx, but these have not been formally studied. Objectives  The present study aims to assess the association of nasal endoscopic features with PND among rhinitis patients. This will guide clinicians to interpret the nasal endoscopic findings appropriately...

BACKGROUND AND AIMS: Cognitive-affective processes, including hypervigilance and symptom-specific anxiety, may contribute to chronic laryngeal symptoms and are potentially modifiable; however, a validated instrument to assess these constructs is lacking. The aims of this study were to develop and validate the Laryngeal Cognitive-Affective Tool (LCAT) instrument. METHODS: This two-phase single-center prospective study enrolled participants from 11/2021 to 6/2023...

BACKGROUND & AIMS: Discerning whether laryngeal symptoms result from gastroesophageal reflux is clinically challenging and a reliable tool to stratify patients is needed. We aimed to develop and validate a model to predict likelihood of gastroesophageal reflux disease (GERD) among patients with chronic laryngeal symptoms. METHODS: This multicenter international study collected data from adults with chronic laryngeal symptoms that underwent objective testing (upper GI endoscopy and/or ambulatory reflux monitoring) between 3/2018-5/2023...

A simple and effective pepsin detection assay is reported based on a pepsin-susceptible peptide (PSP) reporter degradation strategy. PSP, which can be specifically cleaved by pepsin, was modified with fluorescein isothiocyanate (FITC) and biotin at the N- and C-terminals to be used as a reporter for colorimetric detection of dipsticks. A universal lateral flow dipstick consisting of a streptavidin test line for biotin binding and a sample pad immobilized with a gold-labeled polyclonal (rabbit) anti-FITC antibody was used to verify PSP-based pepsin detection...

Esophagogastroduodenoscopy (EGD) is recommended in patients with typical gastroesophageal reflux disease (GERD) symptoms (heartburn, regurgitation, chest pain) in the setting of proton pump inhibitor (PPI) nonresponse. EGD evaluates for erosive disease, assesses antireflux barrier integrity, excludes non-GERD conditions, and, in the absence of erosive findings, is followed by reflux testing.1,2 The diagnostic utility of EGD is less clear in the evaluation for laryngopharyngeal reflux (LPR), and the current reference standard is ambulatory reflux monitoring...

In-person swallow therapy is a primary and effective treatment for dysphagia. However, remote telehealth is now a widely utilized component of healthcare delivery for therapeutic interventions. This study evaluates potential factors influencing attendance at telehealth swallow therapy. Retrospective review of 308 patients referred for telehealth swallow therapy from April 2020-November 2021 included patient referral diagnosis, diagnostic swallowing evaluations, and sociodemographic information including age, race, health insurance, interpreter use, and socioeconomic status...

BACKGROUND: The prevalence of gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) in post-irradiated patients with nasopharyngeal carcinoma (NPC) is unknown. MATERIALS AND METHODS: In a cross-sectional study, 31 NPC and 12 control patients completed questionnaires for GERD/LPR before esophageal manometry and 24-h pH monitoring. The DeMeester score and reflux finding score (RFS) were used to define GERD and LPR, respectively. Risk factors were identified...

BACKGROUND: Machine learning driven clinical decision support tools (ML-CDST) are on the verge of being integrated into clinical settings, including in Otolaryngology-Head & Neck Surgery. In this study, we investigated whether such CDST may influence otolaryngologists' diagnostic judgement. METHODS: Otolaryngologists were recruited virtually across the United States for this experiment on human-AI interaction. Participants were shown 12 different video-stroboscopic exams from patients with previously diagnosed laryngopharyngeal reflux or vocal fold paresis and asked to determine the presence of disease...

OBJECTIVES: Voice disorders have been reported in up to 47% of the geriatric population. Few studies have assessed dysphonia in the elderly, with none examining vocal function in working seniors. This study aims to profile the clinical characteristics of individuals aged 65 years and older, comparing working and non-working seniors. STUDY DESIGN: Retrospective cohort study. METHODS: Medical charts were reviewed for patients aged 65 years and older referred to the McGill University Health Centre Laryngology Clinic (January 2018-March 2020)...

RESEARCH BACKGROUND: The role of dietary habits of patients with laryngopharyngeal reflux (LPR) is comparatively underexplored. The aim of the study is to examine dietary habits, onset and course of the disease as well as the quality of life of patients with LPR. EXPERIMENTAL APPROACH: The results of the modified food frequency questionnaire (FFQ-m) and laryngopharyngeal reflux health-related quality of life (LPR-HRQL) questionnaires were compared between subjects with and without LPR...

BACKGROUND: Laryngopharyngeal reflux has classically referred to gastroesophageal reflux leading to chronic laryngeal symptoms such as throat clearing, dysphonia, cough, globus sensation, sore throat or mucus in the throat. Current lack of clear diagnostic criteria significantly impairs practitioners' ability to identify and manage laryngopharyngeal reflux. AIMS: To discuss current evidence-based diagnostic and management strategies in patients with laryngopharyngeal reflux...

OBJECTIVES: This study aimed to investigate the relation between subjective voice-related symptoms and endoscopic findings in patients with different etiology of voice disorder and vocally healthy subjects with and without laryngopharyngeal reflux (LPR). STUDY DESIGN: Retrospective cross-sectional study. METHODS: The study involved 149 participants (106 female, 43 male) including 125 with various voice disorders (functional, structural, and neurogenic) and 24 vocally healthy individuals...

Objective: To investigate the risk factors for the occurrence of laryngopharyngeal reflux disease in the aged, and to analyze the characteristics of patients with pneumonia. Methods: Patients who underwent 24-hour laryngopharyngeal pH monitoring from June 2020 to July 2022 and the positive patients of those who underwent 24-hour esophageal pH monitoring from March 2017 to July 2022 at the Second Medical Center of the PLA General Hospital were enrolled retrospectively. Positive results of 24-hour laryngopharyngeal reflux monitoring were in the laryngopharyngeal reflux group, and the negative results were in the non-laryngopharyngeal reflux group...

To analyze the predictive value of salivary pepsin for treatment outcomes in laryngopharyngeal reflux (LPR) using multivariate analysis that includes various associated factors. This prospective cohort study was conducted between August 2020 and August 2022. Patients with LPR who had symptoms lasting more than 1 month and a reflux symptom index (RSI) of 14 or higher were enrolled. The participants received a 2-month regimen of proton pump inhibitors (PPIs) treatment and lifestyle modification. Salivary pepsin was checked using fasting saliva before treatment...

OBJECTIVE: This study aims to provide a scoping review and attempts to uncover the possible association between burning mouth disorder and gastroesophageal reflux disease. METHODS: PubMed, EMBASE, Web of Science, the Cochrane Library, Ovid, Scopus, and a search platform (EBSCOhost) were searched from their inception to August 22, 2023. RESULTS: After screening 2795 records, 18 articles were included in the final review, comprising cross-sectional studies (n = 9), case-control studies (n = 5), case reports (n = 2), case series (n = 1), and experimental study (n = 1)...

In recent years, the prevalence of laryngopharyngeal reflux has risen, especially among pediatric patients. The diagnosis of laryngopharyngeal reflux relies on patient history and clinical assessment using the Reflux Finding Score and Reflux Symptom Index as crucial diagnostic tools. Some studies have proposed a link between pepsin and laryngopharyngeal reflux, potentially triggering palatine tonsil hypertrophy. Our study aimed to investigate the correlation between laryngeal and pharyngeal manifestations of laryngopharyngeal reflux through two questionnaires and the presence of pepsin in saliva and palatine tonsils in a pediatric population...

BACKDOWN: In this study, the authors, each for their own skills, on the basis of clinical, psychological, endoscopic investigations, evaluated the probable relationship between the laryngopharyngeal reflux present in gastroesophageal reflux disease, and the dysfunction of the Eustachian tube. At the end of the study, after a phase of medical therapy for GERD, they found that laryngopharyngeal acid reflux was in fact the basis of audiological symptoms and chronic dysfunction of the Eustachian tube...
