Abstract
Importance The autonomic nervous system maintains internal stability by concurrently prioritizing and managing different functions. It is currently not known whether dysfunction at the aerodigestive junction could overwhelm autonomic control and impair other functions. Objective To compare baroreflex sensitivity, a prognostically significant index of the autonomic system's ability to stabilize blood pressure, between patients with predominantly esophagogastric (digestive) and patients with predominantly laryngopharyngeal (aerodigestive) symptoms. Design, Setting, and Participants A cross-sectional study, between 2018 and 2019, of adults undergoing esophagal manometry or transnasal panendoscopy was carried out in a specialist center. The analysis took place between 2023 and 2024. Main Outcomes and Measures Heart rate and blood pressure were recorded and baroreflex sensitivity and heart rate variability were derived. Esophageal physiology was assessed with high-resolution manometry. Results There were 30 and 23 patients in the digestive and aerodigestive groups, respectively. The mean (SD) age was 61 (15) years and there were 26 women and 27 men. Compared with patients in the digestive group, more patients in the aerodigestive group had voice or throat symptoms and fewer had classic reflux symptoms (odds ratio [OR], 5.65; 95% CI, 1.82-17.5; OR, 2.07; 95% CI, 1.28-3.33; and OR, 0.60; 95% CI, 0.38-0.95, respectively). Patients in the aerodigestive group had higher mean (SD) resting heart rate (93 [17] vs 75 [13] min-1; difference of means, -18 min-1; 95% CI, -26 to -10), lower resting mean (SD) arterial pressure (94 [16] vs 104 [23] mm Hg, OR, 10; 95% CI, -1 to 21), lower mean (SD) baroreflex sensitivity (3.77 [0.79] vs 9.76 [2.92] s-3mm Hg-1; OR, 6.0 s-3mmHg-1; 95% CI, 4.7-7.2), and lower mean (SD) parasympathetic-spectrum heart rate variability (0.68 [0.15] vs 1.30 [0.53]; OR, 0.62; 95% CI, 0.39-0.85). There was a correlation between reduced lower esophageal relaxation (integrated relaxation pressure) and reduced baroreflex sensitivity (r = -0.33; 95% CI, -0.58 to -0.03). Conclusions In this cross-sectional study of adults undergoing esophageal manometry or transnasal panendoscopy, patients with laryngopharyngeal symptoms had reduced baroreflex sensitivity, indicating diminished vagal control compared with patients with esophagogastric symptoms. The overwhelmed vagus hypothesis may explain these responses by considering autonomic functions as competing consumers of the finite regulatory resources of a common controller. The regulatory demands of maintaining a safe airway with concurrent laryngopharyngeal sensorimotor dysfunction, superadded to baseline demands for dual speech and aerodigestive control, could overwhelm and force the system to deprioritize less immediate functions like esophageal relaxation and the baroreflex. Measuring baroreflex sensitivity, now possible in routine clinical practice, could enable phenotyping and objective outcome assessment for laryngopharyngeal dysfunction. A neurophysiological model for considering laryngopharyngeal sensorimotor dysfunction could in turn move patient care toward a more holistic autonomic health footing.

Abstract
Gastroesophageal reflux (GER) and eosinophilic esophagitis (EoE) are the most common inflammatory causes of pediatric dysphagia, but several other less prevalent conditions should be considered. These conditions can affect one or several aspects of the swallowing process. In some inflammatory conditions dysphagia may be an early symptom. Esophagoscopy and instrumental swallow studies are often needed to determine the underlying diagnosis and best treatment plan. In some inflammatory conditions dysphagia can portend a worse outcome and need for more aggressive treatment of the underlying condition. Consultations with speech language pathology, gastroenterology, dietetics, allergy/immunology and/or rheumatology are often needed to optimize management.

Abstract
TOPIC IMPORTANCE Laryngeal dysfunction as a cause of chronic refractory cough and episodic dyspnea is often missed, which results in unnecessary testing and delays in diagnosis. Understanding laryngeal roles in breathing and airway protection can help to appreciate the propensity to laryngeal dysfunction with aging, chronic lung disease, and sleep apnea. REVIEW FINDINGS The human larynx is a complex muscular structure that is responsible for multiple roles of breathing, vocalization, coughing, and swallowing. To undertake these activities, the larynx has a high density of sensory and motor innervation. In addition to common embryological origins with the pharynx and esophagus, with which many laryngeal activities are shared, somatomotor and autonomic pathways regulate emotional, cognitive, and complex motor sequence-planning activities within the larynx. Due to its unique location, the larynx is susceptible to infectious and gastroesophageal reflux-related insults. Couple this with key roles in regulation of airflow and mediation of airway protective reflexes, it is not surprising that neuropathic abnormalities and muscle dysfunction frequently develop. The expression of laryngeal dysfunction as hypersensitivity to mechanical, thermal, chemical, and other stimuli leads to exaggerated airway protective reflexes (laryngeal adductor reflex and cough reflex) manifesting as dyspnea and cough. SUMMARY Pulmonologists should incorporate assessment of laryngeal dysfunction during evaluation of chronic refractory cough and dyspnea. Recognition of laryngeal hypersensitivity in the patient with chronic refractory cough can identify patients who may benefit from cough suppression therapies. Similarly, timely identification of inducible laryngeal obstruction may not only resolve episodic dyspnea but lessen the need for unnecessary testing and treatments.

Abstract
OBJECTIVE The objective of this work was to gather an international consensus group to propose a global definition and diagnostic approach of laryngopharyngeal reflux (LPR) to guide primary care and specialist physicians in the management of LPR. METHODS Forty-eight international experts (otolaryngologists, gastroenterologists, surgeons, and physiologists) were included in a modified Delphi process to revise 48 statements about definition, clinical presentation, and diagnostic approaches to LPR. Three voting rounds determined a consensus statement to be acceptable when 80% of experts agreed with a rating of at least 8/10. Votes were anonymous and the analyses of voting rounds were performed by an independent statistician. RESULTS After the third round, 79.2% of statements (N = 38/48) were approved. LPR was defined as a disease of the upper aerodigestive tract resulting from the direct and/or indirect effects of gastroduodenal content reflux, inducing morphological and/or neurological changes in the upper aerodigestive tract. LPR is associated with recognized non-specific laryngeal and extra-laryngeal symptoms and signs that can be evaluated with validated patient-reported outcome questionnaires and clinical instruments. The hypopharyngeal-esophageal multichannel intraluminal impedance-pH testing can suggest the diagnosis of LPR when there is >1 acid, weakly acid or nonacid hypopharyngeal reflux event in 24 h. CONCLUSION A global consensus definition for LPR is presented to improve detection and diagnosis of the disease for otolaryngologists, pulmonologists, gastroenterologists, surgeons, and primary care practitioners. The approved statements are offered to improve collaborative research by adopting common and validated diagnostic approaches to LPR. LEVEL OF EVIDENCE 5 Laryngoscope, 134:1614-1624, 2024.

Instrument adaptation and preliminary validation study of the Laryngeal Hypersensitivity Questionnaire used for assessment of laryngeal symptoms in patients with artificial airways. Aust Crit Care 2024; 37:138-143. [PMID: 38135588 PMCID: PMC10842835 DOI: 10.1016/j.aucc.2023.09.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 01/22/2023] [Accepted: 09/05/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND The Newcastle Laryngeal Hypersensitivity Questionnaire (LHQ) was developed to measure abnormal laryngeal sensation and was originally validated in a patient sample from otolaryngologic and respiratory outpatient clinics. Modification is needed for patients who are mechanically ventilated via an endotracheal tube or a tracheostomy tube. OBJECTIVES We sought to adapt and preliminarily validate a modified version of the LHQ appropriate for nurses and other clinicians to administer in acute hospital settings called the LHQ-Acute (LHQ-A). METHODS Internal consistency and construct validity analyses using secondary data from patients at a tertiary teaching hospital who presented with symptoms of laryngeal irritability/hypersensitivity between September 2012 and October 2013 were performed. RESULTS A total of 131 patients, most complaining of coughing and dysphonia, with a median age of 58 (interquartile range: 48, 66) years and 29 healthy participants with a median age of 62 (interquartile range: 50, 66) years were analysed. The original LHQ was reduced from 14 questions with responses on a 7-point scale to the LHQ-A containing 13 questions with responses on a 4-point scale. Correlations between items of the LHQ and LHQ-A were similar, and internal consistency was excellent and highly comparable, with Cronbach's alpha = 0.906 and 0.902, respectively. CONCLUSIONS The LHQ-A, which has been adapted for nurses and other clinicians to administer to a critically ill patient population, demonstrated comparable reliability and validity to the original LHQ. Validation of the LHQ-A in independent patient populations from acute settings is necessary to better understand norms and changes during recovery from acute illness.

Abstract
INTRODUCTION Laryngeal sensory function in healthy adults was assessed through the delivery of tactile stimuli using Cheung-Bearelly monofilaments. METHODS 37 healthy adults were recruited with 340 tactile stimuli analyzed. Four calibrated tactile stimuli were delivered to three laryngeal sites: false vocal fold (FVF), aryepiglottic fold (AEF), and lateral pyriform sinus (LPS). Primary outcome was the elicitation of laryngeal adductor reflex (LAR). Secondary outcomes were gag, patient-reported laryngeal sensation (PRLS), and perceptual strength. Analysis was performed with mixed effects logistic regression modeling. RESULTS Positive LAR was observed in 35.7%, 70.2%, and 91.2% of stimuli at LPS, AEF, and FVF respectively. LAR rates were significantly associated with laryngopharyngeal subsite (p < 0.001), tactile force (p = 0.001), age (p = 0.022) and sex (p = 0.022). LAR, gag, PRLS, and perceptual strength significantly increased as a more medial laryngeal subsite was stimulated and as stimulus force increased. Each of the ten years of age increase was associated with 19% reduction in odds of LAR (aOR = 0.81, 95% CI [0.68, 0.97]; p = 0.022). Male gender was associated with a 55% reduction in odds of LAR (aOR = 0.45, 95% CI [0.23, 0.89]; p = 0.022). CONCLUSION LAR elicitation capability decreases in the male gender, aging, and a more lateral subsite. This study provides insight into the pathophysiology of hypo- and hyper-sensitive laryngeal disorders and is paramount to making accurate diagnostic assessments and finding novel treatment options for various laryngological disorders.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is associated with many chronic diseases among which is laryngopharyngeal reflux disease (LPRD). OBJECTIVE To investigate the prevalence of laryngopharyngeal reflux (LPR)-related symptoms in patients with OSA using the Reflux Symptoms Score (RSS) and Reflux Symptom Index (RSI). METHODS The medical records and video-recordings of patients with OSA who presented to a tertiary referral center were reviewed. The diagnosis of OSA was made using the STOP-BANG questionnaire and/or polysomnography. The prevalence of LPR-related symptoms was assessed using both the RSS and RSI questionnaires. RESULTS Thirty-nine patients were included in this study. Twenty-seven patients (69.2%) had a positive RSS in comparison to only 7 (17.9%) using the RSI (p = .052). Subgroup analysis of those who had polysomnography (n = 24) showed that 18 patients (75%) had a positive RSS in comparison to only 5 patients (20.8%) using the RSI. Patients in the high-risk category for OSA were also found to have a higher prevalence of LPR-related symptoms using both the RSS and RSI questionnaires in comparison to those in the lower risk categories. CONCLUSION The results of this investigation indicate that the prevalence of LPR-related symptoms is higher using the RSS in comparison to the RSI.

Abstract
BACKGROUND The Reflux Symptom Score (RSS) is a patient-related outcomes measure (PROM) that was developed to diagnose Laryngopharyngeal reflux (LPR), by assessing the severity and frequency of specific symptoms and their respective impact on quality of life (QoL). OBJECTIVE To develop the Arabic version of RSS-12 (Ar-RSS-12), and to assess its validity and reliability. METHOD The RSS-12 was translated from French into Arabic using the forward-backward translation method, and the translated version underwent transcultural validation. A case-control study was conducted at the otolaryngology clinics of a referral hospital, during the period November to December 2022. It included 61 patients with LPR-related symptoms and a Reflux Symptom Index (RSI) score >13, and 61 control without LPR-related symptoms and negative RSI scores ≤13. The internal consistency, internal and external validity, and Test-Retest reliability of Ar-RSS-12 were analyzed. RESULT Patients had significantly higher scores than controls in all 12 items and total Ar-RSS and QoL impact scores, with high Z score values. Item scores showed variable correlation levels with total Ar-RSS score, with ear-nose-throat items showing the strongest correlation (Spearman's rho 0.592-0.866). The QoL scores were more strongly correlated to the symptoms' severity than frequency. The internal consistency was high, with Cronbach's alpha = 0.878. Regarding external validity, correlations with RSI score showed high Spearman's rho values for total Ar-RSS (0.905) and QoL total score (0.903). No statistically significant difference was observed between Test and Retest results in any of the 12 items' score or the total score and QoL, indicating the reproducibility of the test. CONCLUSION The Ar-RSS is a valid and reproducible tool for the screening, assessment, and monitoring of LPR in Arabic speaking patients. The inclusion of symptoms severity and frequency, as well as their individual effects on patient's QoL, support the superior clinical applications of RSS compared to other existing PROMs.

Eur Arch Otorhinolaryngol 2023:10.1007/s00405-023-08000-1. [PMID: 37140740 DOI: 10.1007/s00405-023-08000-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Accepted: 04/24/2023] [Indexed: 05/05/2023]
Abstract
OBJECTIVE To study the diagnostic value of salivary pepsin measurement (Peptest) for detecting gastroesophageal reflux disease (GERD) in laryngopharyngeal reflux (LPR) patients. METHODS Patients with reflux symptoms were consecutively recruited from January 2020 to November 2022. Patients benefited from hypopharyngeal-esophageal impedance-pH monitoring (HEMII-pH), fasting and bedtime saliva collections to measure pepsin. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were evaluated for GERD and LPR patients considering the highest values of pepsin tests at ≥ 16, ≥ 75, and ≥ 216 ng/mL cutoffs. The relationship between HEMII-pH, endoscopic and clinical findings, and pepsin measurements was studied. RESULTS Saliva was collected in 109 LPR patients and 30 individuals with both LPR and GERD. The total number of pharyngeal reflux events was significantly higher in GERD-LPR patients compared with LPR patients (p = 0.008). The mean fasting and bedtime pepsin saliva concentrations were similar between groups. The sensitivity of Peptest in LPR patients was 30.5%, 70.2%, and 84.0% at cutoffs ≥ 16, ≥ 75 and ≥ 216 ng/mL. In GERD-LPR group, Peptest was 80.0%, 70.0%, and 30.0% sensitive. At cutoff 16 ng/mL, Peptest reported PPV of 20.7% and 94.8% in LPR-GERD and LPR groups, respectively. NPV were 73.9% and 8.7% in GERD-LPR and LPR groups, respectively. The consistency analysis between Peptest and HEMII-pH was not significant. Peptest was significantly associated with the number of acid pharyngeal reflux events (rs = 0.182; p = 0.032). CONCLUSION Pepsin saliva measurements appear to be not a reliable diagnostic tool for the detection of GERD in LPR patients. Future studies are needed to determine the place of Peptest in laryngopharyngeal reflux and gastroesophageal reflux diseases.

Abstract
PURPOSE Postswallow voice abnormality is often assumed to indicate the presence of material in the laryngeal airway (MIA), but prior research has not shown definitive evidence of a causal relationship. This study investigated if endoscopically confirmed MIA (prandial material or secretions) generates specific voice quality attributes that can be perceptually identified by experienced listeners. METHOD Forty-four dysphagic adults underwent endoscopic evaluation of swallowing. Time-linked audiovisual recordings of pre- and postswallow phonation were analyzed to determine the presence, amount, and location of prandial material or secretions in the larynx during phonation. Expert listeners completed auditory-perceptual ratings of phonation samples. RESULTS Voice quality ratings did not differ significantly when there was MIA during postswallow phonation. However, judgments of voice quality abnormality for MIA samples were elevated when analyses controlled for effects of baseline dysphonia. Listeners were most likely to perceive voice quality abnormality when larger amounts of secretions were present, as compared to prandial material. Interrater reliability was variable and ranged from low to moderate across perceptual parameters. CONCLUSIONS MIA during phonation occurred for many participants, but perception of voice quality abnormality was variable when MIA was present. Baseline dysphonia is common among individuals with dysphagia and may limit perception of voice quality abnormalities generated by MIA. Secretions in the laryngeal airway may have a greater impact on voice quality parameters.

Abstract
GOAL The aim of this study was to investigate the pepsin values and pH results of gastric juice among the subtypes of gastroesophageal reflux disease (GERD) and functional heartburn. BACKGROUND The major destructive agents of GERD on the esophageal epithelium are gastric acid and pepsin. No precise information about pepsin concentration in gastric juice exists. STUDY Ninety patients with GERD, 39 erosive reflux disease (ERD) Los Angeles (LA) grade A/B, 13 ERD LA grade C/D, 19 nonerosive reflux disease (NERD), 8 esophageal hypersensitivity, 11 functional heartburn, and 24 healthy controls were included in the study. During endoscopy gastric juices from the patients were aspirated and their pH readings immediately recorded. Gastric juice samples were analyzed using Peptest, a lateral flow device containing 2 unique human monoclonal antibodies to detect any pepsin present in the gastric juice sample. RESULTS The highest mean gastric pepsin concentration (0.865 mg/mL) and the lowest median gastric pH (1.4) was observed in the LA grade C/D group compared with the lowest mean gastric pepsin concentration (0.576 mg/mL) and the highest median gastric pH (2.5) seen in the NERD group. Comparing pH, the NERD patient group was significantly higher (P=0.0018 to P=0.0233) when compared with all other GERD patient groups. CONCLUSIONS The basal gastric pepsin level in the healthy control group was comparable to literature values. There was good correlation and a significant linear relationship between the gastric pepsin level and gastric pH within the patient groups. The severity of the GERD disease is related to the lowest pH and the highest pepsin concentration in gastric juice.

Abstract
Background Obstructive sleep apnea syndrome (OSAS) and laryngopharyngeal reflux (LPR) have been found to coexist in the population. OSAS and LPR also share obesity as an important risk factor. However, the relationship between LPR and OSAS remains unclear. This study aimed to correlate LPR as measured by the Reflux Symptom Index (RSI) and the Reflux Finding Score (RFS) with OSAS. Methods This cross-sectional study included sixty-four subjects who underwent anamnesis to complete the RSI and the Epworth Sleeping Scale (ESS). The subjects were then divided into the OSAS and non-OSAS groups based on the Apnea-Hypopnea Index (AHI) obtained through a polysomnography examination. Both groups underwent a flexible fiberoptic nasopharyngolaryngoscopy examination to determine the RFS. LPR was identified based on the RSI and RFS. Results The mean BMI of the OSAS group significantly was higher than the non-OSAS group (p < 0.05). Most of the subjects in the OSAS group exhibited mild-moderate OSAS (AHI 10-29), and severe OSAS occurred in only seven subjects. The mean RSI and RFS values in the OSAS group did not differ significantly from the non-OSAS group (p = 0.34 and p = 0.36, respectively). The proportion of LPR between the mild-moderate OSAS group, the severe OSAS group, and the non-OSAS group did not differ significantly (p = 1.00). RSI and RFS did not significantly correlate with AHI. Based on RSI, the proportion of LPR between the ESS (+) and ESS (-) groups did not significantly differ (adjusted p = 0.062). The proportion of LPR based on RFS was almost equal between the ESS (+) and ESS (-) groups (p = 0.817). Conclusions The BMI of the OSAS group was significantly higher than the non-OSAS group. There was no significant difference in RSI and RFS between the OSAS and non-OSAS groups. There was no significant correlation between RSI and AHI, or between RFS and AHI. There was no significant difference in the proportion of RSI between the ESS (+) and the ESS (-) groups.

Abstract
Eating and drinking generate sequential mechanosensory signals along the digestive tract. These signals are communicated to the brain for the timely initiation and regulation of diverse ingestive and digestive processes - ranging from appetite control and tactile perception to gut motility, digestive fluid secretion and defecation - that are vital for the proper intake, breakdown and absorption of nutrients and water. Gut mechanosensation has been investigated for over a century as a common pillar of energy, fluid and gastrointestinal homeostasis, and recent discoveries of specific mechanoreceptors, contributing ion channels and the well-defined circuits underlying gut mechanosensation signalling and function have further expanded our understanding of ingestive and digestive processes at the molecular and cellular levels. In this Review, we discuss our current understanding of the generation of mechanosensory signals from the digestive periphery, the neural afferent pathways that relay these signals to the brain and the neural circuit mechanisms that control ingestive and digestive processes, focusing on the four major digestive tract parts: the oral and pharyngeal cavities, oesophagus, stomach and intestines. We also discuss the clinical implications of gut mechanosensation in ingestive and digestive disorders.

Abstract
Despite continued surgical advancements in the field of cardiothoracic transplantation, post-operative complications remain a burden for the patient and the multidisciplinary team. Lesser-known complications including swallowing disorders (dysphagia), and voice disorders (dysphonia), are now being reported. Such disorders are known to be associated with increased morbidity and mortality in other medical populations, however their etiology amongst the heart and lung transplant populations has received little attention in the literature. This paper explores the potential mechanisms of oropharyngeal dysphagia and dysphonia following transplantation and discusses optimal modalities of diagnostic evaluation and management. A greater understanding of the implications of swallowing and laryngeal dysfunction in the heart and lung transplant populations is important to expedite early diagnosis and management in order to optimize patient outcomes, minimize allograft injury and improve quality of life.

Abstract
OBJECTIVE To measure the latency of laryngeal adductor reflex (LAR) motion onset at 2 laryngopharyngeal subsites using calibrated aesthesiometers. STUDY DESIGN Cross-sectional. SETTING Academic institution. METHODS Twenty-one asymptomatic, healthy subjects (11 male, 10 female) underwent laryngopharyngeal sensory testing with tactile stimuli delivered to the aryepiglottic fold and medial pyriform sinus using 30-mm Cheung-Bearelly monofilaments (4-0 and 5-0 nylon sutures) via channeled flexible laryngoscope. The LAR onset latency, defined as the first visual detection of ipsilateral vocal fold adduction following tactile stimulation, was measured with frame-by-frame analysis of video recordings. RESULTS The overall mean LAR latency across both subsites and stimulation forces was 176.6 (95% CI, 170.3-183.0) ms, without significant difference between subsites or forces. The critical value for LAR response latency prolongation at the .01 significance level was 244 ms. At 30 frames/s video capture resolution, LAR response latency ≥8 frame intervals would indicate abnormal prolongation. CONCLUSION Aesthesiometer-triggered LAR latency appears to be invariant over an 8.7-dB force range and between the aryepiglottic fold and medial pyriform sinus subsites in controls. Laryngeal adductor reflex latency incongruences between stimulation forces or laryngopharyngeal subsites may serve as pathophysiological features to dissect mechanisms of upper aerodigestive tract disorders. LEVEL OF EVIDENCE Level 3B.

Abstract
BACKGROUND AND OBJECTIVES Swallowing disorders lead to chronic lung aspiration. Early detection and treatment of aspiration in children with dysphagia are important to prevent lung damage. Diagnosis of aspiration, which may be silent, requires an instrumental study such as fiberoptic endoscopic evaluation of swallowing (FEES). Despite its usefulness, it is rarely practiced by pediatric pulmonologists. This study aimed to evaluate the feasibility and utility of FEES performed in the pediatric respiratory unit of a tertiary hospital, analyze the clinical characteristics, endoscopic findings and proposed treatments, and identify the factors associated with penetration or aspiration. METHODS Medical records of 373 children with suspected aspiration who were referred to the pediatric respiratory unit for FEES were reviewed retrospectively. Clinical characteristics, FEES findings, and the proposed treatments were analyzed. RESULTS Laryngeal penetration/aspiration was seen in 47.9% of the patients. The most common associated conditions were neurological disease and prematurity. The most frequently observed endoscopic finding was altered laryngeal sensitivity (36.5%). Intervention was recommended in 54.2% of the patients. Complications were not seen during any of the procedures. The multivariate logistic regression model revealed an independent association between aspiration and alterations in laryngeal sensitivity (odds ratio [OR], 5.68), pharyngeal pooling (OR, 11.47), and post-swallowing food residues (OR, 8.08). CONCLUSIONS The FEES procedure performed by pediatric pulmonologists is a reliable method for diagnosing aspiration in children. It can be safely executed by trained pulmonologists, and significant endoscopic signs other than aspiration can guide in the diagnosis and management recommendations.

Abstract
Purpose The larynx is a uniquely situated organ, juxtaposed between the gastrointestinal and respiratory tracts, and endures considerable immunological challenges while providing reflexogenic responses via putative mucosal mechanoreceptor afferents. Laryngeal afferents mediate precise monitoring of sensory events by relay to the internal branch of the superior laryngeal nerve (iSLN). Exposure to a variety of stimuli (e.g., mechanical, chemical, thermal) at the mucosa-airway interface has likely evolved a diverse array of specialized sensory afferents for rapid laryngeal control. Accordingly, mucosal mechanoreceptors in demarcated laryngeal territories have been hypothesized as primary sources of sensory input. The purpose of this article is to provide a tutorial on current evidence for laryngeal afferent receptors in mucosa, the role of mechano-gated ion channels within airway epithelia and mechanisms for mechanoreceptors implicated in laryngeal health and disease. Method An overview was conducted on the distribution and identity of iSLN-mediated afferent receptors in the larynx, with specific focus on mechanoreceptors and their functional roles in airway mucosa. Results/Conclusions Laryngeal somatosensation at the cell and molecular level is still largely unexplored. This tutorial consolidates various animal and human researches, with translational emphasis provided for the importance of mucosal mechanoreceptors to normal and abnormal laryngeal function. Information presented in this tutorial has relevance to both clinical and research arenas. Improved understanding of iSLN innervation and corresponding mechanotransduction events will help shed light upon a variety of pathological reflex responses, including persistent cough, dysphonia, and laryngospasm.

Abstract
OBJECTIVES Patients undergoing oesophagectomy frequently experience malnutrition, which in combination with the catabolic effects of surgery can result in loss of muscle mass and function. Safe swallowing requires preservation of muscle mass. Swallowing dysfunction puts postoperative patients at risk for aspiration and pneumonia. Modified Barium Swallow Study (MBSS) enables assessment of postoperative swallowing impairments. The current study assessed incidence and risk factors associated with swallowing dysfunction and restricted diet at discharge in patients after oesophagectomy in a high-volume surgical centre. METHODS Patients with an MBSS after oesophagectomy were identified between March 2015 to April 2020 at a high-volume surgical centre. Swallowing was quantitatively evaluated on MBSS with the Rosenbek Penetration-Aspiration Scale (PAS). Muscle loss was evaluated clinically with preoperative hand grip strength (HGS). Univariable and multivariable logistic and linear regression analyses were performed. RESULTS 129 patients (87% male; median age 66 years) underwent oesophagectomy with postoperative MBSS. Univariate analysis revealed older age, preoperative feeding tube, lower preoperative HGS and discharge to non-home were associated with aspiration or penetration on MBSS. Age and preoperative feeding tube remained as independent predictors in the multivariable analysis. Both univariate and multivariable analyses revealed increased age and preoperative feeding tube were associated with diet restrictions at discharge. CONCLUSIONS Swallowing dysfunction after oesophagectomy is correlated with increased age and need for preoperative enteral feeding tube placement. Further research is needed to understand the relationship between muscle loss and aspiration with the goal of enabling preoperative physiological optimisation and patient selection.

Abstract
A major component of gastric acid is hydrochloric acid (HCl), which can activate transient receptor potential vanilloid 1 (TRPV1). In the present study, we investigated how sustained laryngeal TRPV1 activation affects the frequency of the swallowing reflex. Experiments were carried out on 85 male Sprague-Dawley rats. The effects of short and sustained application of chemicals (3 µl of 0.1 N HCl or capsaicin) on the frequency of swallowing and on time-dependent changes in the occurrence of swallowing evoked by supralaryngeal nerve stimulation were determined. To evaluate vascular permeability of the larynx, Evans blue dye was intravenously injected after 5 or 60 min of sustained TRPV1 activation. SB366791 (a TRPV1 inhibitor) and Cap/QX-314 (a TRPV1-expressed neuronal inhibitor) significantly inhibited HCl/capsaicin-induced swallowing, but air flow-induced swallowing was not affected. Although the number of air flow-induced swallows followed by capsaicin stimulation was not affected within 5 min, it was significantly reduced by 60-min capsaicin or HCl application. The swallowing threshold associated with supralaryngeal nerve stimulation did not significantly change throughout the recording period. Evans blue dye concentrations in the larynx were significantly higher at 60 min in the 10-5 M capsaicin group than in the control group. Our results suggest that sustained TPRV1 activation not only desensitizes TRPV1 but also inactivates mechanoreceptors, which may be attributed to increases in vascular permeability and edema, as part of an inflammatory process.NEW & NOTEWORTHY Although a transient receptor potential vanilloid 1 (TRPV1) inhibitor or TRPV1-expressed neuronal inhibitor significantly inhibited HCl/capsaicin-evoked swallowing, air flow-induced swallowing was not affected. The number of air flow-induced swallows was significantly reduced within 60 min of TRPV1 activation. Evans blue dye concentration in the larynx increased 60 min after capsaicin application. TPRV1 activation not only desensitizes TRPV1 but also inactivates mechanoreceptors caused by increases in vascular permeability and edema.

Abstract
OBJECTIVES To evaluate laryngopharyngeal sensation at specific subsites using a novel adaptation of a buckling force aesthesiometer for delivery of calibrated tactile stimuli. STUDY DESIGN Cross-sectional. METHODS Twenty-two healthy adults (12 men, 10 women) were tested for responses to tactile forces, using 30-mm 6-0, 5-0, and 4-0 nylon monofilaments to map sensation of the aryepiglottic (AE) fold, lateral pyriform sinus (PS), and medial PS bilaterally. The outcome measures were the laryngeal adductor reflex (LAR) and patient reported rating of perceptual strength. RESULTS Rates of triggered LAR response grew monotonically with increasing tactile force at a mean (SD) stimulus duration of 663 (164) msec across all three subsites. The AE fold and medial PS had similar profiles and were the most responsive, while the lateral PS was the least responsive. Low force (6-0) response rate was ≤14% for all subsites. High force (4-0) response rate was 91% for AE fold and medial PS, and 23% for lateral PS. The perceptual strength gradient was in the lateral to medial trajectory. CONCLUSION Normative data for LAR response rates to low, medium, and high stimulation forces will be useful to assess sensory dysfunction in a variety of laryngopharyngeal disorders, including aspiration, dysphagia, chronic cough, and spasmodic dysphonia. In turn, that information will guide the creation of innovative treatments. LAR response profiles to low and high force stimuli will inform the development of screening tools to diagnose laryngopharyngeal hypersensitivity and hyposensitivity conditions.

Abstract
INTRODUCTION The reflux symptom index (RSI) has been designed to raise the clinical suspicion of laryngopharyngeal reflux (LPR) in patients presenting with ear, nose, and throat symptoms. OBJECTIVE To develop a Turkish version of the RSI (Tr-RSI) and to evaluate its internal consistency, reliability, and clinical validity METHODS: The RSI was translated into Turkish. A total of 44 asymptomatic control subjects without LPR and 62 patients with LPR were enrolled into this study. The patients were treated with diet and behavioral modifications combined with 20 mg of rabeprazole twice daily for 3 months. All individuals were asked to fill the Tr-RSI. Participants in the control group were asked to refill the Tr-RSI after 1 week, whereas those in the patient group after treatment. Test-retest reliability, validity, and internal consistency were computed. RESULTS The Cronbach's alpha value of Tr-RSI was 0.959, indicating excellent internal consistency. The single-measurement intra-class correlation coefficient absolute agreement was 0.948 (with 95% confidence interval of 0.907-0.971), indicating good test-retest reliability. The Tr-RSI scores for total and each item were significantly higher in the LPR patient group than in the control group (P < 0.001). In the LPR patient group, the posttreatment Tr-RSI scores for each item and total were significantly lower than the pretreatment scores (P < 0.001). CONCLUSION The Tr-RSI was successfully created. It can be used with strong internal consistency, high test-retest reliability, and optimal clinical validity.

Abstract
Objective Few studies have investigated pharyngeal intraluminal baseline impedance (BI) levels in patients with laryngopharyngeal reflux (LPR). The aim of this study was to compare intraluminal BI levels between patients with LPR and healthy controls. Study Design Retrospective case series. Setting Tertiary care medical center. Subjects and Methods We conducted a retrospective analysis of 24-hour multichannel intraluminal impedance (MII)–pH monitoring results from patients with suspected LPR complaining of reflux symptoms. Patients with suspected LPR were divided into 2 groups according to the 24-hour MII-pH monitoring (LPR group: patients with symptoms with reflux events ≥1, symptom but no reflux [SNR] group: patients with symptoms but no reflux event). Healthy controls were recruited and also underwent 24-hour MII-pH monitoring. We compared the esophageal and pharyngeal BI levels and ratios between 3 groups. Results Pharyngeal BI levels in the LPR group were significantly higher than in the healthy controls. In addition, the pharyngeal BI levels in the SNR group were significantly higher than in the healthy controls. All ratios of pharyngeal to distal esophageal BI levels in the LPR and SNR group were significantly higher than in the healthy controls. However, there were no significant differences in esophageal BI levels and ratios between the 3 groups. Conclusion We found that the pharyngeal BI levels were higher in patients with LPR than in healthy controls. In addition, the pharyngeal BI levels measured by 24-hour MII-pH monitoring in patients with LPR symptoms, but without a reflux episode, were higher than in the healthy controls.

Abstract
OBJECTIVES The purpose of this systematic review was to summarize and qualitatively analyze published evidence elucidating the prevalence of dysphagia and detail alterations in swallowing function in patients with OSAS. METHODS Computerized literature searches were performed from four search engines. The studies were selected based on the inclusion and exclusion criteria. The studies were screened using Covidence (Cochrane tool) and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement standards (PRISMA-2009). A total 2645 studies were initially retrieved, of which a total of 17 studies met inclusion criteria. Two reviewers, blinded to each other, evaluated level and strength of evidence using the Oxford Centre for Evidence-based Medicine Levels of Evidence and QualSyst, respectively. RESULTS Dysphagia prevalence ranged from 16 to 78% among the eligible studies. Studies varied in operational definitions defining swallowing dysfunction (dysphagia) and method used to assess swallowing function. Approximately 70% of eligible studies demonstrated strong methodological quality. The majority of studies (n = 11; 65%) reported pharyngeal swallowing impairments in patients with OSAS, including delayed initiation of pharyngeal swallow and penetration/aspiration. CONCLUSION This systematic review describes swallowing function in patients with OSAS. However, due to the variability in defining OSAS and dysphagia, in the assessment method used to determine dysphagia, and heterogeneity of study designs, true prevalence is difficult to determine. Clinicians involved in the management of OSAS patients should employ validated assessment measures to determine if swallow dysfunction is present.

Abstract
OBJECTIVES Sensation is an integral component of laryngeal control for breathing, swallowing, and vocalization. Laryngeal sensation is assessed by elicitation of the laryngeal adductor reflex (LAR), a brainstem-mediated adduction of the true vocal folds. During Flexible Endoscopic Evaluations of Swallowing (FEES), the touch method can be used to elicit the LAR to judge laryngeal sensation. Despite the prevalence of this method in clinical practice and research, prior studies have yet to examine inter- and intra-rater reliability. METHODS Four speech-language pathologists rated 125 randomized video clips for the presence, absence, or inability to rate the LAR. Fifty percent of video clips were re-randomized and re-rated 1 week later. Raters then created guidelines and participated in formal consensus training sessions on a separate set of videos. Ratings were repeated post-training. RESULTS Overall inter-rater reliability was fair (κ = 0.22) prior to training. Pre-training intra-rater reliability ranged from fair (κ = 0.35) to almost perfect (κ = 0.89). Inter-rater reliability significantly improved after training (κ = 0.42, P < .001), though agreement did not reach prespecified acceptable levels (κ ≥ 0.80). Post-training intra-rater reliability ranged from moderate (κ = 0.49) to almost perfect (κ = 0.85). CONCLUSION Adequate inter-rater reliability was not achieved when rating isolated attempts to elicit the LAR. Acceptable within-rater reliability was observed in some raters 1 week after initial ratings, suggesting that ratings may remain consistent within raters over a short period of time. Limitations and considerations for future research using the touch method are discussed.

Abstract
INTRODUCTION Gastro-esophageal reflux disease (GERD) indicates a gastroesophageal reflux that causes symptoms such as pain, and needs medical therapy, and may result in complications such as erosive esophagitis, aspiration pneumonia. Here, we review if it exists a real link between clinical presentation of some respiratory diseases such as asthma, chronic cough, cystic fibrosis and laryngopharyngitis and GERD. EVIDENCE ACQUISITION This review was conducted employing 2 databases: PubMed and Science Direct. EVIDENCE SYNTHESIS Asthma may lead to reflux, and reflux could exacerbate asthma or cause asthma-like symptoms. Prevalence of GERD in children with asthma ranged from as low 32% to as high 80%. There are several studies where the use of proton pump inhibitors (PPIs) and histamine H2 receptor antagonists lead to inconclusive results. The relation of chronic unexplained cough to GERD remains controversial in children and pediatric guidelines do not currently recommend empirical GERD treatment trials for pediatric chronic cough. Gastroesophageal reflux is more frequent in patients with cystic fibrosis (CF) than general population. Although PPIs are regularly prescribed in approximately half of the patients with CF, there are no specific guidelines for treatment of reflux in CF and it was shown that chronic treatment with PPIs was correlated to possible increased risk of exacerbations. CONCLUSIONS The pathogenesis of GER-related respiratory symptoms is multifactorial. The causal relationship between these two conditions may be difficult to prove also with the aid of supporting tests. Multichannel intraluminal impedance associated with pH-metry (pH/MII) detect all gastroesophageal reflux episodes accompanied with a bolus movement and classify GER episodes according to their content (liquid, gas and mixed), pH value and proximal extension. There are no consistent evidences confirming the validity of medical therapy in reflux with respiratory symptoms.

Abstract
OBJECTIVE Reflux disease is common in patients with oropharyngeal dysphagia, but the impact of reflux on oropharyngeal swallowing physiology is not known. This study uses objective measures of swallowing function from modified barium swallow studies to describe the pathophysiology of dysphagia in a group of patients whose only associated condition is reflux. STUDY DESIGN Retrospective chart review. SETTING Tertiary care voice and swallowing clinic. SUBJECTS AND METHODS The Swallowing Database at the University of Utah was queried for patients with a diagnosis of reflux without additional conditions known to affect swallowing function. Pharyngeal transit time (TPT), distance of hyoid elevation (Hmax), maximum opening size of the upper esophageal sphincter (UESmax), area of pharynx at maximum constriction (PAmax), airway closure timing relative to the arrival of the bolus at the UES, and penetration/aspiration (Pen/Asp) score were assessed. RESULTS Of the 122 patients who met inclusion criteria for the study, 42% had normal pharyngeal swallowing function, 57% had at least 1 abnormal swallowing measure, and 47.5% demonstrated a delay in airway closure relative to arrival of the bolus at the UES on at least 1 swallow. The incidence of prolonged TPT, diminished Hmax, poor UESmax, and enlarged PAmax were 2.5%, 8%, 4%, and 11.5%, respectively. Sixty percent with a delay in airway closure had a normal Pen/Asp score. CONCLUSION A delay in airway closure relative to the arrival of the bolus at the UES is the most common abnormality of swallowing function found in patients with reflux-associated dysphagia but may not be identified using the Pen/Asp score.

Abstract
OBJECTIVES To investigate the therapeutic benefit of proton pump inhibitors (PPIs) over placebo in patients with laryngopharyngeal reflux (LPR) and to analyze the epidemiological factors of heterogeneity in the literature. METHODS An electronic literature search was conducted to identify articles published between 1990 and 2018 about clinical trials describing the efficiency of medical treatment(s) on LPR. First, a meta-analysis of placebo randomized controlled trials (RCTs) comparing PPIs versus placebo was conducted according to diet. The heterogeneity, response to PPIs, and evolution of clinical scores were analyzed for aggregate results. Second, a systematic review of diagnosis methods, clinical outcome of treatment, and therapeutic regimens was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS The search identified 1,140 relevant publications, of which 72 studies met the inclusion criteria for a total of 5,781 patients. Ten RCTs were included in the meta-analysis. The combined relative risk was 1.31 in favor of PPIs and increased to 1.42 when patients did not receive diet recommendations. Randomized controlled trials were characterized by a significant heterogeneity due to discrepancies in clinical therapeutic outcomes, diagnosis methods (lack of gold standard diagnostic tools), and therapeutic scheme. The epidemiological analysis of all articles supports the existence of these discrepancies in the entire literature. In particular, many symptoms and signs commonly encountered in LPR are not assessed in the treatment effectiveness. The lack of diagnosis precision and variability of inclusion criteria particularly create bias in all reported and included articles. CONCLUSION This meta-analysis supports a mild superiority of PPIs over placebo and the importance of diet as additional treatment but demonstrates the heterogeneity between studies, limiting the elaboration of clear conclusions. International recommendations are proposed for the development of future trials. Laryngoscope, 129:1174-1187, 2019.

Abstract
Despite improvements in operative strategies for esophageal resection, anastomotic leaks, fistula, postoperative pulmonary complications, and chylothorax can occur. Our review seeks to identify potential risk factors, modalities for early diagnosis, and novel interventions that may ameliorate the potential adverse effects of these surgical complications following esophagectomy.

Abstract
Exercise-inducible laryngeal obstruction (EILO) has been recognized as a not rare respiratory problem in youth practicing sports. The aim of the study was to test the mechanosensitivity of the larynx, and to identify the factors affecting it in a group of youth with proven EILO. Laryngeal sensory testing was performed in 54 adolescents and young adults with EILO. Laryngeal mucosal alterations were assessed according to the Reflux Finding Score (RFS). The data concerning diseases possibly affecting the upper airway, findings of previously performed flexible videolaryngoscopy during exercise, and RFS score were compared between the participants with laryngeal hyposensitivity and those with normal sensitivity. The participants with isolated vocal folds' adduction during an EILO attack were compared with those who demonstrated supraglottis collapse. Testing revealed an increased threshold for mechanical stimuli in 81.5% of participants. Among participants with hyposensitivity, there were significantly more participants with dysphagia during EILO attacks than among the participants with normal laryngeal sensitivity. The hyposensitivity group had a significantly higher RFS score compared with the other group. Isolated vocal folds' approximation was only observed in 11.9% of participants. These participants were younger and had asthma more frequently compared with the others. Only 16.9% of participants with EILO did not state symptoms related to gastroesophageal reflux. The decreased mechanosensitivity was detected in the majority of participants, suggesting that laryngopharyngeal reflux can be an important etiological factor. The problem of breathing difficulties during sport activities in youth can also be associated with the disproportionate growth of the respiratory tract.

Abstract
Background/Aims Neurologically impaired patients frequently suffer from gastrointestinal tract problems, such as gastroesophageal reflux disease (GERD). In this study, we aimed to define the risk factors for GERD in neurologically impaired children. Methods From May 2006 to March 2014, 101 neurologically impaired children who received 24-hour esophageal pH monitoring at Severance Children’s Hospital were enrolled in the study. The esophageal pH finding and the clinical characteristics of the patients were analyzed. Results The reflux index was higher in patients with abnormal electroencephalography (EEG) results than in those with normal EEG results (p=0.027). Mitochondrial disease was associated with a higher reflux index than were epileptic disorders or cerebral palsy (p=0.009). Patient gender, feeding method, scoliosis, tracheostomy, and baclofen use did not lead to statistical differences in reflux index. Age of onset of neurological impairment was inversely correlated with DeMeester score and reflux index. Age at the time of examination, the duration of the disease, and the number of antiepileptic drugs were not correlated with GER severity. Conclusions Early-onset neurological impairment, abnormal EEG results, and mitochondrial disease are risk factors for severe GERD.

Abstract
Objective The primary objective was to determine the prevalence of Helicobacter pylori among patients with laryngopharyngeal reflux. The secondary objective was determining if H pylori eradication leads to greater symptom improvement in patients with laryngopharyngeal reflux as compared with standard proton pump inhibitor therapy alone. Data Sources EMBASE, Cumulative Index to Nursing and Allied Health Literature, MEDLINE, World Health Organization International Clinical Trials Registry Platform, European Union Clinical Trials Register, Cochrane Library databases of clinical trials, and ClinicalTrials.gov. Review Methods A systematic review was performed of studies assessing the diagnosis or treatment of H pylori among patients with laryngopharyngeal reflux. Randomized controlled trials, cohort studies, case-control studies, and case series were included. A meta-analysis of prevalence data and assessment of heterogeneity was performed on relevant studies. Results Fourteen studies were analyzed in the review, with 13 eligible for the meta-analysis. We determined that the prevalence of H pylori among patients with laryngopharyngeal reflux was 43.9% (95% confidence interval, 32.1-56.5). The heterogeneity of studies was high, with an overall I2 value of 92.3%. We were unable to quantitatively assess findings for our secondary outcome, since H pylori identification and treatment were not the primary focus of the majority of studies. Conclusion There is a high rate of H pylori infection among patients with laryngopharyngeal reflux. The infection rate in North America and Western Europe has not been adequately studied. There is insufficient evidence to make a recommendation regarding the testing and treatment of H pylori infection among patients with laryngopharyngeal reflux.

Abstract
Flexible endoscopic evaluation of swallowing with sensory testing (FEESST) is a comprehensive endoscopic assessment of the sensory and motor components of a swallow. Previous studies addressing patient safety issues with respect to FEESST included relatively small numbers of patients and paid almost no attention to patient characteristics. The purpose of this study was to determine the incidence of FEESST-related complications in the outpatient and inpatient settings and to analyze patient diagnoses that led to the performance of FEESST. We performed a prospective study of FEESST complications in 1,340 consecutive evaluations performed over a 4 1/2-year period. The primary outcome variables were incidence of epistaxis and airway compromise. The secondary outcome variable was underlying patient diagnoses. The incidence of epistaxis was 1 in 1,340 (0.07%). There were no instances of airway compromise. Stroke was the most common reason for the performance of FEESST (343; 25.6%), followed by cardiac-related dysphagia (298; 22.2%) following open heart surgery (169/298; 56.7%), heart attack, congestive heart failure, or new arrhythmia. The remaining causes were head and neck cancer (207; 15.4%), pulmonary disease (141; 10.5%), chronic neurologic disease (124; 9.3%), and acid reflux disease (80; 6.0%). We conclude that FEESST is a relatively safe procedure for the sensory and motor assessment of dysphagia in a cohort of patients with a wide variety of underlying diagnoses. The emergence of cardiac surgery as a common cause of dysphagia warrants further study.

Abstract
OBJECTIVES: To evaluate the relationships between laryngeal inflammation assessed using the Reflux Finding Score (RFS), laryngeal sensory function, and apnea severity in patients with obstructive sleep apnea (OSA). METHODS: Endoscopic sensory testing (EST) was performed with subsequent blinded scoring from video of RFS. An RFS > 7 was indicative of increased inflammatory change. RESULTS: Of 34 patients evaluated, 29 had OSA (apneahypopnea index [AHI] ≥ 15 events/h) at polysomnography. Increased inflammation was present in 26/29 (90%), with changes suggestive of laryngopharyngeal reflux. There were significant correlations between: inflammation and OSA severity (eg, RFS vs AHI, r = 0.57, P < 0.001); inflammation and laryngeal sensory impairment (EST detection threshold and pressure required to elicit the laryngeal adductor reflex, LAR); and the degree of sensory impairment and OSA severity. CONCLUSIONS: Laryngeal inflammation is prevalent among OSA patients and correlates with laryngeal sensory dysfunction, attenuation of the LAR, and apnea severity. EBM rating: C-4

Abstract
Background and Objectives. Swallowing difficulty is considered one of the nonspecific symptoms that many patients with laryngopharyngeal reflux complain of. However, the relationship between laryngopharyngeal reflux and swallowing problems is not clear. The purpose of this work is to explore correlation between swallowing-related problems and laryngopharyngeal reflux (LPR) in a group of patients diagnosed with oropharyngeal pH monitoring and to study the effect of laryngopharyngeal reflux on the patients' self-perception of swallowing problems. Methods. 44 patients complaining of reflux-related problems were included in the study. Patients underwent 24-hour oropharyngeal pH monitoring and were divided into positive and negative LPR groups based on the pH monitoring results. All patient filled out the Dysphagia Handicap Index (DHI) and Reflux Symptom Index (RSI) questionnaires. Comparison was made between the positive and negative LPR groups regarding the results of the DHI and RSI ratings. Also, correlation between DHI scores, RSI scores, and pH monitoring results was studied. Results. Significant difference was reported between positive and negative LPR groups regarding DHI scores, RSI scores, and overall rating of swallowing difficulty. There was significant correlation demonstrated between DHI scores, RSI scores, and 24-hour oropharyngeal pH results. Conclusion. Laryngopharyngeal reflux appears to have a significant impact on patients' self-perception of swallowing problems as measured by DHI.

Abstract
BACKGROUND The current study was conducted to evaluate long-term disease control, survival, and functional outcomes after surgical and nonsurgical initial treatment for patients with T4 larynx cancer. METHODS Demographics, disease stage, and treatment characteristics were reviewed for 221 sequential patients treated for T4 laryngeal squamous cell cancer at a single institution between 1983 and 2011. Survival and disease control outcomes were calculated. RESULTS The median follow-up time was 47 months (71 months for patients still alive at the time of analysis). The overall 5-year and 10-year overall survival rates were 52% and 29%, respectively, and the corresponding disease-free survival rates were 57% and 48%, respectively. Overall 5-year and 10-year locoregional control rates were 78% and 67%, respectively, and the corresponding rates for freedom from distant metastasis were 76% and 74%, respectively. On both univariate and multivariate analyses, lymph node-positive disease at the time of presentation was associated with overall mortality (P<.0001). Patients treated with laryngectomy followed by postlaryngectomy radiotherapy (161 patients) achieved better initial locoregional control than patients treated with a laryngeal preservation (LP) approach (60 patients) throughout the follow-up period (log-rank P<.007) yet the median overall survival times were equal for both groups (64 months; 95% confidence interval 47-87 months and 38-87 months, respectively [P =.7]). Patients treated with an LP approach had a tracheostomy rate of 45% and an any-event aspiration rate of 23%. Rates of high-grade dysphagia at the time of last follow-up were worse for patients treated with an LP approach (P<.01). CONCLUSIONS Surgery and postoperative radiotherapy can produce substantial long-term cancer control and survival rates for patients with T4 larynx cancer. Caution should be taken when selecting patients for initial nonsurgical treatment because of significant rates of functional impairment despite survival equivalence.

Abstract
Objectives To map mechanoreceptor response in various regions of the laryngopharynx. Methods Five patients with suspected laryngopharyngeal reflux and six healthy control subjects underwent stimulation of mechanoreceptors in the hypopharynx, interarytenoid area, arytenoids, aryepiglottic folds, and pyriform sinuses. The threshold stimuli evoking sensation and eliciting laryngeal adductor reflex were recorded. Results In controls, an air pulse with 2 mmHg pressure evoked mechanoreceptor response in all regions, except bilateral aryepiglottic folds of one control. In patients, stimulus intensity to elicit mechanoreceptor response ranged between 2 mmHg and 10 mmHg and varied among the regions. Air pulse intensity differed between right and left sides of laryngopharyngeal regions in the majority of patients. Conclusion Laryngopharyngeal mechanoreceptor response was uniform among regions and subjects in the healthy group. Patients with suspected laryngopharyngeal reflux showed inter- and intra-regional variations in mechanoreceptor response. Laryngopharyngeal sensory deficit in patients with suspected laryngopharyngeal reflux is not limited to aryepiglottic folds.
