RESUMO
BACKGROUND: Laryngopharyngeal reflux (LPR) is a common otolaryngologic diagnosis. Treatment of presumed LPR remains challenging, and limited frameworks exist to guide treatment. METHODS: Using RAND/University of California, Los Angeles (UCLA) Appropriateness Methods, a modified Delphi approach identified consensus statements to guide LPR treatment. Experts independently and blindly scored proposed statements on importance, scientific acceptability, usability, and feasibility in a four-round iterative process. Accepted measures reached scores with ≥ 80% agreement in the 7-9 range (on a 9-point Likert scale) across all four categories. RESULTS: Fifteen experts rated 36 proposed initial statements. In round one, 10 (27.8%) statements were rated as valid. In round two, 8 statements were modified based on panel suggestions, and experts subsequently rated 5 of these statements as valid. Round three's discussion refined statements not yet accepted, and in round four, additional voting identified 2 additional statements as valid. In total, 17 (47.2%) best practice statements reached consensus, touching on topics as varied as role of empiric treatment, medication use, lifestyle modifications, and indications for laryngoscopy. CONCLUSION: Using a well-tested methodology, best practice statements in the treatment of LPR were identified. The statements serve to guide physicians on LPR treatment considerations.

BACKGROUND AND PURPOSE: Several clinical and demographic factors relate to anatomic spread of adult-onset isolated dystonia, but a predictive model is still lacking. The aims of this study were: (i) to develop and validate a predictive model of anatomic spread of adult-onset isolated dystonia; and (ii) to evaluate whether presence of tremor associated with dystonia influences model predictions of spread. METHODS: Adult-onset isolated dystonia participants with focal onset from the Dystonia Coalition Natural History Project database were included. We developed two prediction models, one with dystonia as sole disease manifestation ("dystonia-only") and one accepting dystonia OR tremor in any body part as disease manifestations ("dystonia OR tremor"). Demographic and clinical predictors were selected based on previous evidence, clinical plausibility of association with spread, or both. We used logistic regressions and evaluated model discrimination and calibration. Internal validation was carried out based on bootstrapping. RESULTS: Both predictive models showed an area under the curve of 0.65 (95% confidence intervals 0.62-0.70 and 0.62-0.69, respectively) and good calibration after internal validation. In both models, onset of dystonia in body regions other than the neck, older age, depression and history of neck trauma were predictors of spread. CONCLUSIONS: This predictive modeling of spread in adult-onset isolated dystonia based on accessible predictors (demographic and clinical) can be easily implemented to inform individuals' risk of spread. Because tremor did not influence prediction of spread, our results support the argument that tremor is a part of the dystonia syndrome, and not an independent or coincidental disorder.

OBJECTIVES: To compare patterns of laryngopharyngeal reflux (LPR) diagnosis and management over time by American Broncho-Esophagological Association (ABEA) members. METHODS: American Broncho-Esophagological Association members completed an online questionnaire focused on LPR evaluation and management in 2012; responses were compared to a 2002 survey. RESULTS: Four hundred twenty-six members were emailed, of whom 63 (14.8%) responded. In both time periods, throat clearing, heartburn, globus, arytenoid edema, and erythema were considered highly related to LPR. Management in 2012 differed as respondents more commonly treated LPR empirically (82.6% vs 56.3%, P = .036). When adjunctive testing was ordered, dual pH probe were less frequently utilized in 2012 (61.5% vs 78.3%, P = .029). Either esophagogastroduodenoscopy (EGD) or transnasal esophagoscopy (TNE) was used more often in 2012 compared to EGD alone in 2002 (63.8% vs 42.4%, P = .020). Dual pH probe was regarded as the most sensitive and specific evaluation for LPR in both surveys, while the perceived sensitivity/specificity of EGD in 2012 was half that reported in 2002 (28.0% vs 56.3%, P = .003). CONCLUSION: Attitudes of ABEA members toward empiric treatment and adjunctive tests have changed between 2012 and 2002. While pH probe testing remains the test regarded as most sensitive/specific for evaluation of LPR, empiric management has become more common. Meanwhile, EGD use has increased despite a significant decrease in its perceived sensitivity/specificity.

OBJECTIVE: This study aimed to describe current patterns for diagnosis and treatment of laryngopharyngeal reflux (LPR) and analyze differences between laryngologists and non-laryngologists. METHODS: American Academy of Otolaryngology-Head and Neck Surgery and American Broncho-Esophagological Association members were invited to complete an online survey regarding evaluation, diagnosis, and treatment of LPR. Subgroup analysis was performed to identify differences between respondents who completed laryngology fellowships (LF) and those who did not (NL). RESULTS: Of 159 respondents, 40 were LF. Video documentation of laryngopharyngeal exams was almost universal among LF (97% vs 38%, P < .0001). Use of rigid (100%, P = .002) and flexible distal-chip technologies (94%, P = .004) was more common among LF. Diagnostic criteria were similar between the groups, with symptoms of heartburn, globus, and throat clearing thought most suggestive of LPR. Adjunctive tests most commonly used were barium esophagram and dual-probe pH testing with impedance. Laryngology fellowship-trained respondents used dual pH probes with impedance more often (P = .004). They were more likely to prescribe twice daily proton pump inhibitors with concurrent H2-blocker medication initially (P = .004) and to treat for longer than 4 weeks (P = .0003). CONCLUSION: Otolaryngologists are in agreement on symptoms and physical features of LPR; however, significant differences exist between laryngologists and non-laryngologists on the use of adjunctive testing and treatment strategies.

OBJECTIVE: To evaluate the efficacy of distal esophageal mean nocturnal baseline impedance (MNBI), a general marker of esophageal mucosal barrier integrity, in predicting laryngopharyngeal reflux (LPR) and symptomatic response to acid reflux therapy. METHODS: This retrospective study analyzed 173 patients who presented with symptoms of laryngopharyngeal reflux and underwent 24-h multichannel intraluminal impedance-pH (MII-pH) testing. Mean nocturnal baseline impedance values were calculated and assessed for their association and ability to predict LPR symptoms, MII-pH results, treatment response, and other markers of LPR. RESULTS: Notably, 153 of the 173 patients were tested off acid suppression medication and included in statistical analysis. Based on the MII-pH probe data, 108 (71%) patients had LPR, 8 (5%) had gastroesophageal reflux disease (GERD), and 37 (24%) were without pathologic reflux. Distal esophageal MNBI of LPR patients was significantly lower in LPR patients than patients with negative studies (1332 ± 94.8 vs. 2158 ± 173.5, p = 0.001). Among 118 patients who trialed antireflux therapy, a distal esophageal MNBI cutoff value of <1580 Ω was an independent predictor of treatment response (OR = 4.148 [1.877-9.189]). This value better predicted improvement with antireflux therapy for LPR than other objective MII-pH probe data, which were not independent predictors of treatment response. CONCLUSION: Distal esophageal MNBI values may have value in the diagnosis of LPR and potentially predict medication responsiveness in LPR patients.

OBJECTIVES: Limited research exists evaluating the impact of social determinants of health in influencing care pathways for patients with dysphagia. A better understanding of whether these determinants correlate to altered care and resource utilization is essential as it relates to patient outcomes. STUDY DESIGN: Retrospective chart review. METHODS: All adult patients seen at a tertiary midwestern hospital were screened for ICD codes of dysphagia diagnoses from 2009 to 2019. Demographic information was collected from these patients with dysphagia including sex, race, ethnicity, and insurance status. Subgroup analysis was performed to assess referral pattern rates and types of diagnostic interventions ordered (none, videofluoroscopic swallow study, esophagram, and esophagogastroduodenoscopy). RESULTS: A total of 31,858 patients with dysphagia were seen at our institution during the study period, with a majority being female (56.36%), Caucasian (79.83%), and publicly insured (63.16%), at a median age of 60.35 years. There were no significant care delivery pattern differences based on geography/zip code analyses. African American patients were significantly more likely to have imaging or interventions performed (odds ratio [OR] 1.463, p = 0.005). Patients with public insurance also had higher rates of diagnostic study utilization (OR 1.53, p = 0.01). Only 3% of all patients with dysphagia were seen by laryngologists. CONCLUSION: No significant differences were seen in dysphagia evaluation modalities based on zip code analyses surrounding this tertiary care facility. African American patients and those with public insurance had significantly higher utilization of subsequent testing and intervention for dysphagia care. Further studies are necessary to delineate causes and outcome differences for these measurable differences in dysphagia care pathways. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1139-1146, 2024.

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.

OBJECTIVES: We sought to review the dysphagia-related outcomes and quality of life in a series of patients with upper esophageal sphincter (UES) dysfunction treated with cricopharyngeal (CP) botulinum toxin (BTX) injection, and to identify patient characteristics or CP muscle histologic features that predict efficacy of BTX injection. METHODS: A retrospective chart review was performed on patients with UES dysfunction who underwent CP BTX injection. Dysphagia-related quality-of-life questionnaires based on the Eating Assessment Tool (EAT-10) were mailed to patients. RESULTS: Forty-nine patients (30 female, 19 male; average age, 59 +/- 16 years) with UES dysfunction have been treated at our institution with CP BTX injection since 2000. Seventeen of these patients also underwent CP myotomy. Injections of BTX were occasionally repeated after the treatment effect subsided, and the BTX dose varied widely (average, 39 +/- 19 units). Improvement in symptoms was noted by 65% of patients. The overall complication rate was minimal, although many patients complained of transient worsening of dysphagia after CP BTX injection. Biopsy specimens of the CP muscle were evaluated in the subset of patients with CP BTX injection who proceeded to myotomy, with results of neuropathic, myopathic, and mixed histologic subtypes. The EAT-10 scores demonstrated a general trend toward improved swallowing outcomes after CP BTX injection. CONCLUSIONS: This study reviewed findings from the largest published series of BTX treatment of UES dysfunction and evaluated the efficacy, patient satisfaction, and complications of this procedure. Dysphagia-related quality-of-life outcomes appear to be improved after CP BTX injection.

OBJECTIVES: Mean nocturnal baseline impedance (MNBI) is a measure of the esophageal epithelial barrier function calculated via high-resolution impedance manometry and can be used as a diagnostic tool and treatment response predictor for gastroesophageal reflux disease (GERD). However, its utility for laryngopharyngeal reflux (LPR) has been minimally studied. We aimed to investigate the relationship of MNBI between patients with suspected LPR, healthy controls, and their 24-h multichannel intraluminal impedance-pH (MII-pH) study results. METHODS: Retrospective patient series analysis was performed of patients with suspected LPR and healthy controls who underwent 24-h MII-pH monitoring. MNBI values were calculated from impedance channels at the level of the hypopharynx, proximal esophagus, and distal esophagus. We compared these MNBI values between the subject groups with secondary analysis on MII-pH results, reflux symptom index, reflux findings score, DeMeester score, and salivary pepsin levels. RESULTS: Twenty-three patients with suspected LPR and 14 healthy controls were enrolled. Decreased distal esophageal MNBI was found to be significantly decreased in patients with suspected LPR compared with healthy controls (p < 0.01) and in subjects with positive MII-pH studies compared to negative MII-pH studies (p < 0.01). There were no significant correlations of MNBI at the hypopharynx or proximal esophagus. CONCLUSION: Distal esophageal MNBI has significant correlations with many phenotypic and biological markers of LPR. These findings indicate that MNBI has the potential to be applied to LPR, similar to its emerging use as a diagnostic tool and treatment response predictor for GERD.

OBJECTIVE: More than 20% of the US population suffers from laryngopharyngeal reflux. Although dietary/lifestyle modifications and alginates provide benefit to some, there is no gold standard medical therapy. Increasing evidence suggests that pepsin is partly, if not wholly, responsible for damage and inflammation caused by laryngopharyngeal reflux. A treatment specifically targeting pepsin would be amenable to local, inhaled delivery, and could prove effective for endoscopic signs and symptoms associated with nonacid reflux. The aim herein was to identify small molecule inhibitors of pepsin and test their efficacy to prevent pepsin-mediated laryngeal damage in vivo. METHODS: Drug and pepsin binding and inhibition were screened by high-throughput assays and crystallography. A mouse model of laryngopharyngeal reflux (mechanical laryngeal injury once weekly for 2 weeks and pH 7 solvent/pepsin instillation 3 days/week for 4 weeks) was provided inhibitor by gavage or aerosol (fosamprenavir or darunavir; 5 days/week for 4 weeks; n = 3). Larynges were collected for histopathologic analysis. RESULTS: HIV protease inhibitors amprenavir, ritonavir, saquinavir, and darunavir bound and inhibited pepsin with IC50 in the low micromolar range. Gavage and aerosol fosamprenavir prevented pepsin-mediated laryngeal damage (i.e., reactive epithelia, increased intraepithelial inflammatory cells, and cell apoptosis). Darunavir gavage elicited mild reactivity and no discernable protection; aerosol protected against apoptosis. CONCLUSIONS: Fosamprenavir and darunavir, FDA-approved therapies for HIV/AIDS, bind and inhibit pepsin, abrogating pepsin-mediated laryngeal damage in a laryngopharyngeal reflux mouse model. These drugs target a foreign virus, making them ideal to repurpose. Reformulation for local inhaled delivery could further improve outcomes and limit side effects. LEVEL OF EVIDENCE: NA.

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol. Consistent with prior data, prospective observation of 487 iSGS patients for 5 years showed treatment effectiveness differed by modality. Cricotracheal resection maintained the lowest rate of recurrent operation (5%), followed by endoscopic resection with adjuvant medical therapy (30%) and endoscopic dilation (50%). These data support the initial observations and continue to provide value to providers and patients navigating longitudinal decision-making. Level of evidence: 2-prospective cohort study.

OBJECTIVES: Laryngotracheal separation (LTS) is an uncommonly performed but highly effective procedure for intractable aspiration in patients with amyotrophic lateral sclerosis and other neurodegenerative conditions. Previously published series have noted rates of postoperative tracheocutaneous fistula formation as high as 1 in 3 patients. This report details the use of a muscle flap-reinforced imbrication technique to reduce the incidence of fistula formation after LTS surgery. METHODS: All patients who underwent LTS surgery at the reporting institutions between 2004 and 2010 were identified. The principal diagnosis, patient characteristics, the presence of a preexisting tracheotomy, and postoperative complications were recorded. We describe the technique for imbrication closure of the proximal stump with strap muscle reinforcement. RESULTS: Thirteen patients (10 male, 3 female; median age, 53 years; interquartile range, 45 to 66 years) underwent the LTS procedure; amyotrophic lateral sclerosis was the principal diagnosis in 8 of the 13 patients. Six patients had a preexisting tracheotomy. None developed tracheocutaneous fistula, hematoma, or wound infection. Two patients required stomaplasty at a later date. CONCLUSIONS: Strap muscle flap-reinforced imbrication closure of the proximal tracheal stump after LTS surgery allows for a low incidence of postoperative fistula formation.

OBJECTIVES: Although oropharyngeal neoplasia can often lead to dysphagia, salivary gland tumors rarely grow within the tongue base. We present the case of a 75-year-old man with adenoid cystic carcinoma of the base of the tongue causing profound dysphagia and weight loss, and provide a current literature review and update on the management of these rare tumors. METHODS: We present a case report and a literature review. RESULTS: Physical examination performed at the initial visit revealed a firm right base-of-tongue mass with no palpable lymphadenopathy. Flexible fiberoptic laryngoscopy confirmed a large submucosal mass at the right base of the tongue that obscured the right vallecula. Histopathologic analysis of the operative biopsy specimens revealed the classic features of adenoid cystic carcinoma. Treatment included radical pharyngotomy with wide local excision and primary closure, followed by postoperative radiation treatment. CONCLUSIONS: We demonstrate the clinical examination findings and histopathologic characteristics of this disease, and review the literature for clinical treatment recommendations for this rare cause of dysphagia.

Objective: To determine the impact of patient demographics and social determinants of health on treatment pathways for unilateral vocal fold paralysis (UVFP) at a tertiary laryngology clinic. Study design: Retrospective medical record review. Methods: Patient demographics (age, gender, race, ethnicity, and insurance status) were extracted for adults diagnosed with UVFP between 2009 and 2019. Odds ratios for the associations between sociodemographic factors and UVFP treatment pathways were determined by chi-square analyses. Results: A total of 1490 UVFP diagnoses were identified during the study period with the majority being female (58%), White (85%), non-Hispanic (97%), and publicly insured (54%). Five treatment pathways were identified: observation, injection laryngoplasty, voice therapy, laryngeal framework surgery/thyroplasty, and reinnervation surgery. There were 538 patients who underwent observation, 512 injection laryngoplasty, 366 voice therapy, 136 thyroplasty, and 26 laryngeal reinnervation surgery. Males were more likely to undergo injection laryngoplasty than females (OR 1.32; CI 1.08-1.61), whereas females were more likely to undergo voice therapy (OR 1.39; CI 1.09-1.76). Patients with public insurance (OR 1.48; CI 1.03-2.14) and Hispanics (OR 2.60; CI 1.18-5.72) were more likely to undergo thyroplasty. Patients who underwent reinnervation surgery were younger than those in other treatment pathways (median: 39.1 years vs. 50.7-56.1 years). Conclusions: Gender, ethnicity, and insurance status were significantly associated with specific UVFP treatment pathways. Patients with public insurance were more likely to undergo surgical intervention than voice therapy. This data overall supports differences in care pathway utilization for UVFP based on social determinants of health. Level of evidence: Level IV.
RESUMO
OBJECTIVE: To evaluate the association between patient socioeconomic and demographic factors and tertiary care utilization for dysphonia in a localized metropolitan area of the American Midwest. METHODS: Multivariate regression analysis was used to correlate patient demographics and population level data (e.g., age, gender, race, insurance, median income, education level) with tertiary laryngology utilization for dysphonia care at our institution between 2000 and 2019. Initial analyses characterized tertiary laryngology utilization rates for all regional ZIP codes and correlated these data with census information for household income and education. Dysphonia patient demographics were compared among populations cared for in our entire academic Otolaryngology department, our health system, and the regional population. RESULTS: Among 1,365,021 patients in our health system, there were 7066 tertiary laryngology visits with a diagnosis of dysphonia. Dysphonia patients as compared to the overall health system were older (62.0 vs. 50.8 years), more likely to be female (63.7 vs. 50.2%) and more likely to have insurance (98.4 vs. 87.5%, all p < .001). Patient and population-level factors including insurance status, education, and black race showed positive correlation with laryngology utilization while median income did not. CONCLUSIONS AND RELEVANCE: Insurance status, education level, and race correlated with utilization of tertiary laryngology services for the evaluation of dysphonia in our community, while median income did not. Black patients utilized tertiary laryngology care at higher rates compared to departmental and regional population utilization data. These results underscore important demographic and disease-specific factors that may affect utilization of subspecialty care in Otolaryngology. LEVEL OF EVIDENCE: IV.
RESUMO
OBJECTIVES/HYPOTHESIS: To identify the most influential publications in laryngology since 2000. STUDY DESIGN: Modified Delphi process. METHODS: Samples of laryngologists drawn from editors of leading journals, organization officers, and thought leaders were invited to participate in a modified Delphi identification of influential laryngology papers. Influential was defined as follows: yielding meaningful practice changes, catalyzing further work as a foundation for an important topic, altering traditional views, or demonstrating durability over time. Quality and validity were not among the selection criteria. Each participant nominated 5 to 10 papers in Round 1. These nominations, augmented with papers from bibliometric analysis, were narrowed further in Round 2 as participants identified their top 20. The 40 papers with the most Round 2 votes were discussed by video conference and then subjected to Round 3 voting, with each participant again selecting their top 20 most influential papers. Final results were collated by the number of Round 3 votes. RESULTS: Sixteen of 18 invited laryngologists participated overall (all 16 in Rounds 1 and 3; 14 in Round 2). Twenty-one papers were identified as most influential. One paper appeared on all 16 Round 3 lists; three papers with eight (50%) votes each were lasted to make the list. Eleven of these 21 focused on voice; three each related to cancer, airway, and swallowing; and one encompassed all of these clinical areas. CONCLUSIONS: This list of 21 influential laryngology papers serves to focus further research, provides perspective on recent advances within the field, and is an educational resource for trainees and practicing physicians.

OBJECTIVES: Zenker's diverticulum (ZD) is a common source of dysphagia with a well-established surgical treatment history. Variations may exist between practitioners in the preoperative, intraoperative, and postoperative management of patients with ZD because of recent evolutions in surgical approach toward an endoscopic technique. METHODS: An online survey instrument was prepared and forwarded to the membership of the American Broncho-Esophagological Association (ABEA) to ascertain the current practice patterns of its members regarding numerous care parameters for patients with ZD. RESULTS: Data on preoperative evaluation, operative care, postoperative management, and recalled incidence of complications, including mediastinitis, were evaluated. Subgroup analysis demonstrated significant differences in multiple care parameters for those surgeons who predominantly perform endoscopic operations (more than 80% willingness to perform endoscopic operations) compared to those who occasionally perform endoscopic operations (less than 80%), including average case number, advancement of oral intake, hospital discharge, use of antibiotics, and views on the efficacy of endoscopic surgical techniques. These changes were noted despite similar times since graduation from training for the two groups. CONCLUSIONS: These data present a contemporary snapshot of clinical care patterns of the ABEA membership for patients with ZD and suggest differences in care patterns for surgeons with a higher enthusiasm for endoscopic techniques and larger case volumes.

OBJECTIVE: Laryngopharyngeal reflux (LPR) is a common affliction that contributes to laryngeal inflammation, symptoms that impact quality of life, and life-threatening illnesses such as cancer. Effective treatment strategies for LPR are lacking. Pepsin is a proinflammatory and carcinogenic element of refluxate. Investigation of molecular pathways involved in pepsin-mediated damage may lead to identification of novel biomarkers and therapeutic targets for LPR. In this study, RNA sequencing was used to examine changes in human laryngeal epithelial cells following brief pepsin insult. Cells were immortalized to generate a model to aid future study of laryngeal injury and therapeutics. STUDY DESIGN: In vitro translational. METHODS: Laryngeal epithelial cells were cultured from a patient without signs or symptoms of LPR or laryngeal cancer. Cells were treated with 0.1 mg/ml pepsin for 1 hour or normal growth media (control) prior to RNA sequencing. Cells were immortalized via HPV E6/7 and characterized by microscopy, immunohistochemistry, G-banding, and soft agar assay. RESULTS: Three hundred ninety-seven genes exhibited differences in expression with pepsin treatment (P < .05). Pathway analysis revealed association with cancer and related signaling processes including dysregulation of cancer-associated molecules, Metastasis-Associated Lung Adenocarcinoma Transcript 1 and KRT82, and the long-noncoding RNA, lipoprotein receptor-related protein 1 (LRP1)-AS, which regulates the putative pepsin receptor LRP1. CONCLUSIONS: A single, brief exposure to pepsin activated cancer-associated signaling pathways in laryngeal cells in vitro, revealing novel mechanisms by which chronic reflux may contribute to carcinogenesis. The cell line developed herein represents a novel tool in which to investigate pepsin-dysregulated pathways identified by RNA sequencing and disparities of tumor proneness of laryngeal subsites.

OBJECTIVES: The gastric H+/K+ ATPase proton pump has previously been shown to be expressed in the human larynx, however its contribution to laryngopharyngeal reflux (LPR) signs, symptoms and associated diseases such as laryngeal cancer is unknown. Proton pump expression in the larynx of patients with LPR and laryngeal cancer was investigated herein. A human hypopharyngeal cell line expressing the proton pump was generated to investigate its effects. STUDY DESIGN: In-vitro translational. METHODS: Laryngeal biopsies were obtained from three LPR and eight LSCC patients. ATP4A, ATP4B and HRPT1 were assayed via qPCR. Human hypopharyngeal FaDu cell lines stably expressing proton pump were created using lentiviral transduction and examined via transmission electron microscopy and qPCR for genes associated with inflammation or laryngeal cancer. RESULTS: Expression of ATP4A and ATP4B was detected in 3/3 LPR, 4/8 LSCC-tumor and 3/8 LSCC-adjacent specimens. Expression of ATP4A and ATP4B in FaDu elicited mitochondrial damage and expression of IL1B, PTGS2, and TNFA (P < .0001); expression of ATP4B alone did not. CONCLUSIONS: Gastric proton pump subunits are expressed in the larynx of LPR and LSCC patients. Mitochondrial damage and changes in gene expression observed in cells expressing the full proton pump, absent in those expressing a single subunit, suggest that acid secretion by functional proton pumps expressed in upper airway mucosa may elicit local cell and molecular changes associated with inflammation and cancer.

OBJECTIVES: To examine whether social determinants of health (SDH) factors are associated with time to diagnosis, treatment selection, and time to recurrent surgical intervention in idiopathic subglottic stenosis (iSGS) patients. METHODS: Adult patients with diagnosed iSGS were recruited prospectively (2015-2017) via clinical providers as part of the North American Airway Collaborative (NoAAC) and via an online iSGS support community on Facebook. Patient-specific SDH factors included highest educational attainment (self-reported), median household income (matched from home zip code via U.S. Census data), and number of close friends (self-reported) as a measure of social support. Main outcomes of interest were time to disease diagnosis (years from symptom onset), treatment selection (endoscopic dilation [ED] vs cricotracheal resection [CTR] vs endoscopic resection with adjuvant medical therapy [ERMT]), and time to recurrent surgical intervention (number of days from initial surgical procedure) as a surrogate for disease recurrence. RESULTS: The total 810 participants were 98.5% female, 97.2% Caucasian, and had a median age of 50 years (IQR, 43-58). The cohort had a median household income of $62 307 (IQR, $50 345-$79 773), a median of 7 close friends (IQR, 4-10), and 64.7% of patients completed college or graduate school. Education, income, and number of friends were not associated with time to diagnosis via multivariable linear regression modeling. Univariable multinominal logistic regression demonstrated an association between education and income for selecting ED versus ERMT, but no associations were noted for CTR. No associations were noted for time to recurrent surgical procedure via Kaplan Meier modeling and Cox proportional hazards regression. CONCLUSIONS: Patient education, income, and social support were not associated with time to diagnosis or time to disease recurrence. This suggests additional patient, procedure, or disease-specific factors contribute to the observed variations in iSGS surgical outcomes.
