Abstract
OBJECTIVE There is a link between laryngopharyngeal reflux (LPR) and the formation of benign vocal fold lesions (BVFLs). However, previous studies have mainly focused on LPR suggested by symptoms and signs, rather than objectively diagnosed LPR via pharyngeal pH monitoring. We, therefore, conducted a Meta-analysis to evaluate the association between pharyngeal pH monitoring diagnosed LPR and the odds of BVFLs. DATA SOURCES Relevant observational studies were identified by searching PubMed, Embase, Cochrane Library, and Web of Science. REVIEW METHODS We evaluated between-study heterogeneity using the Cochrane Q test and estimated the I2 statistic. Random-effects models were used when significant heterogeneity was observed; otherwise, fixed-effects models were used. RESULTS Thirteen datasets from 9 studies were included. Among them, 493 were diagnosed with LPR and 344 had BVFLs. LPR was related to a higher odds of BVFLs (odds ratio: 3.26, 95% confidence interval: 1.84-5.76, P < .001) with moderate heterogeneity (P for Cochrane Q test = .006, I2 = 57%). Subgroup analyses showed that the association was similar in studies with only pharyngeal pH monitoring (Restech), with double-probe or 3-site pH monitoring, and with 24-hour multichannel intraluminal impedance-pH monitoring (P for subgroup difference = .15). In addition, subgroup analysis showed consistent results in studies from Asia and Europe (P for subgroup analysis = .12), and the association seemed to be consistent for vocal Reinke's edema, nodules, and polyps (P for subgroup difference = .09). CONCLUSION Pharyngeal pH monitoring diagnosed LPR is associated with the formation of BVFLs.

Abstract
The vocal folds (VFs) are constantly exposed to mechanical stimulation leading to changes in biomechanical properties, structure, and composition. The development of long-term strategies for VF treatment depends on the characterization of related cells, biomaterials, or engineered tissues in a controlled mechanical environment. Our aim was to design, develop, and characterize a scalable and high-throughput platform that mimics the mechanical microenvironment of the VFs in vitro. The platform consists of a 24-well plate fitted with a flexible membrane atop a waveguide equipped with piezoelectric speakers which allows for cells to be exposed to various phonatory stimuli. The displacements of the flexible membrane were characterized via Laser Doppler Vibrometry (LDV). Human VF fibroblasts and mesenchymal stem cells were seeded, exposed to various vibratory regimes, and the expression of pro-fibrotic and pro-inflammatory genes was analyzed. Compared to current bioreactor designs, the platform developed in this study can incorporate commercial assay formats ranging from 6- to 96-well plates which represents a significant improvement in scalability. This platform is modular and allows for tunable frequency regimes.

Abstract
Laryngopharyngeal reflux (LPR) is a variant of gastroesophageal reflux disease (GERD) in which gastric refluxate irritates the lining of the aerodigestive tract and causes troublesome airway symptoms or complications. LPR is a prevalent disease that creates a significant socioeconomic burden due to its negative impact on quality of life, tremendous medical expense, and possible cancer risk. Although treatment modalities are similar between LPR and GERD, the diagnosis of LPR is more challenging than GERD due to its non-specific symptoms/signs. Due to the lack of pathognomonic features of endoscopy, mounting evidence focused on physiological diagnostic testing. Two decades ago, a dual pH probe was considered the gold standard for detecting pharyngeal acidic reflux episodes. Despite an association with LPR, the dual pH was unable to predict the treatment response in clinical practice, presumably due to frequently encountered artifacts. Currently, hypopharygneal multichannel intraluminal impedance-pH catheters incorporating two trans-upper esophageal sphincter impedance sensors enable to differentiate pharyngeal refluxes from swallows. The validation of pharyngeal acid reflux episodes that are relevant to anti-reflux treatment is, therefore, crucial. Given no diagnostic gold standard of LPR, this review article aimed to discuss the evolution of objective diagnostic testing and its predictive role of treatment response.

Abstract
OBJECTIVES To analyze voice outcomes and lesion regression in patients with vocal fold polyps treated in-office using lasers. STUDY DESIGN Systematic review and meta-analysis. METHODS The search was performed in the Medline, Embase, and Cochrane databases using the preferred reporting items for systematic review and meta-analyses framework. There were no limitations to the year of publication and the search included studies looking at voice outcomes and lesion evolution of in-office laser treatment for vocal fold polyps measured through voice-handicap index, GRB, acoustic analysis or aerodynamics measures. Risk of bias was assessed using Cochrane's ROBINS-I tool for observational studies. Data analysis was performed SPSS software with a significance level of 5%. RESULTS We identified 167 articles, 10 of which met the inclusion criteria and were analyzed. The total number of participants was 242. Meta-analysis showed significant improvement in voice handicap index-10 scores (95% CI, [0.86; 1.45]) and decrease in GRB score (95% CI, [1.09; 4.13]) after in-office laser therapy. It also showed significant improvement in percent shimmer (95% CI, [0.26; 1.01]), and significant increase in maximum phonation time (95% CI, [-0.92; -0.18]). CONCLUSIONS Laser therapy an outpatient office setting is a reliable alternative to classical phono-microsurgery. Results show Office-based laser therapy of vocal fold polyps results in a significant improvement in subjective voice outcomes measures. This subjective improvement in voice quality is associated with partial or complete disease regression on laryngeal examination and an increase in maximum phonation time.

Abstract
PURPOSE To investigate the diagnostic value of combined multi-timepoint salivary pepsin testing (MTPSPT) and hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH) for laryngopharyngeal reflux (LPR) and whether an appropriate reduction in the duration of HEMII-pH would affect the accuracy of diagnosis of LPR. METHODS Recruited patients were studied with both MTPSPT and HEMII-pH. The diagnosis of LPR was based on the occurrence of > 1 reflux event and/or positive results on any of the MTPSPT. The diagnostic value of combined diagnosis was studied through combining a breakdown of the 24-h HEMII-pH finding and the results of the MTPSPT. The diagnostic value was expressed in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS Based on 24-h HEMII-pH and MTPSPT, the positive rate of LPR was 83.33% and 74.69%, respectively. According to the combined diagnosis, the positive rate of LPR was 90.74%. The sensitivity and specificity of the combined diagnosis both were 89.51% and 100%, when the HEMII-pH intervals were 7 a.m.-6 p.m. and 7 a.m.-7 p.m., respectively. However, when the monitoring time was extended to 8 p.m. and bedtime, the sensitivity, specificity, PPV and NPV of the combined diagnosis both were 100%. CONCLUSIONS The combination of MTPSPT and HEMII-pH increased the sensitivity and accuracy of diagnosis of LPR. For patients with positive MTPSPT results, the duration of HEMII-pH can be appropriately shortened to reduce patient sufferings.

Abstract
PURPOSE To explore the correlation between detection results of pepsin in vocal fold polyp tissues and the postoperative efficacy. METHODS The clinical data of 112 patients with vocal fold polyp who received surgical procedures in our hospital from June 2019 to March 2021 were retrospectively analyzed. The vocal fold morphology and vocal acoustic function were assessed at postoperative week 12. Using binary logistic regression, we explored whether the factors, ie, detection result of pepsin in vocal fold polyp tissue, microscopic suturing, the use of CO2 laser, and the history of smoking, affected the postoperative morphological repair of vocal fold polyps. Then, to observe and compare the influence of the detection results of pepsin on the recovery of vocal acoustic function, we divided the enrolled patients into the pepsin group and the pepsin-free group based on the postoperative detection results of pepsin in the polyp tissues by immunohistochemistry, RESULTS: In the 112 patients with vocal fold polyps, positive staining of pepsin in the postoperative samples was found in 76 patients (67.86%) and negative in 36 (32.14%). Totally 80 patients returned to normal in vocal fold morphology, among whom 32 (88.89%) were in pepsin-free group and 48 (63.16%) in pepsin group. Binary logistic regression showed that pepsin was a clinically significant indicator that affected the postoperative morphological recovery of the vocal fold (P = 0.003). Although hoarse voice was improved in all patients at postoperative week 12, the differences were statistically significant in the proportion of patients with grade, roughness, breathiness, asthenia, strain class G, voice handicap index, maximum phonation time, Jitter, Shimmer and noise-to-harmonic ratio between the pepsin group and the pepsin-free group (P < 0.05), with the pepsin-free group being superior to the pepsin group in the improvement of vocal acoustic function. CONCLUSION Pepsin in vocal fold polyps is a clinically significant indicator affecting the postoperative morphological recovery and acoustic efficacy, and patients with negative pepsin are superior to those with positive pepsin in the postoperative recovery of vocal fold morphology and function.

Abstract
OBJECTIVE Laryngopharyngeal reflux (LPR) causes laryngopharyngeal hypersensitivity and laryngeal muscle hyperfunction, which may result in hard voice onset in patients with LPR. The purpose of this study is to examine the incidence of hard voice onset in patients with LPR and the effects of hard voice onset on objective voice function in patients with LPR. METHODS Forty patients with confirmed LPR were enrolled in the LPR group, and 40 healthy subjects were enrolled in the non-LPR group. Subjects underwent laryngeal high-speed videoendoscopy, and the presence or absence of hard voice onset in each subject was determined by two experienced laryngologists based on whether glottal closure was complete or incomplete before vocal fold vibration. Based on the results, the subjects with LPR were divided into a hard voice onset group and a non-hard voice onset group. The voice onset time (VOT) was measured and compared between the hard and non-hard voice onset groups within the LPR group. Laryngeal aerodynamic assessment was also carried out on the LPR group, and subglottal pressure, phonation threshold pressure (PTP), glottal resistance, and mean flow rate were measured. The voice acoustic signals of subjects were additionally analyzed in the LPR group, and the fundamental frequency, jitter, shimmer, and noise-harmony ratio were determined. The kappa statistic, chi-square test and independent-samples t test in SPSS were used for statistical analysis. RESULTS The two laryngologists had substantial inter-rater consistency on the evaluation of hard voice onset and non-hard voice onset, with a kappa statistic of 0.71. In the LPR group, 42.5% of patients had hard voice onset (17/40), significantly more than in the non-LPR group (8/40, 20%) (P < 0.05). The VOT in the LPR group was significantly longer than in the non-LPR group (P < 0.05). Within the LPR group, the VOT, PTP and shimmer were significantly greater in the hard voice onset group than in the non-hard voice onset group (all P < 0.05). The other laryngeal aerodynamic parameters and acoustic parameters were not significantly different between the hard voice onset group and the non-hard voice onset group (P > 0.05). CONCLUSION Changes in vocal production may occur in LPR patients, causing them to be more susceptible to hard voice onset. The patients with hard voice onset require longer VOT and greater PTP to initiate phonation.

Abstract
Objective:To investigate the effect of tissue pepsin expression of vocal polyps on the postoperative curative effect. Methods:Retrospectively analyze the data of 112 patients diagnosed with vocal cord polyps and undergone surgery from June 2019 to March 2021. The cases were divided into positive group and negative group according to the immunohistochemical pepsin expression. The preoperative reflux symptom index (RSI) and the reflux finding score (RFS) were compared, and the recovery of the voice acoustic function and postoperative vocal cord morphology were analyzed. Results:Among the postoperative specimens of 112 patients,76 cases were positive for pepsin staining, accounting for 67.9%, and 36 cases were negative, accounting for 32.1%. In the pepsin-positive group, 48 cases of vocal cord morphology returned to normal, and 20 cases remained scar or edema in the operation area, 8 cases of polyps relapsed; in the pepsin-negative group, a total of 32 cases of vocal cord morphology returned to normal, 4 cases of remained scar or edema in the operation area, no relapsed cases, the difference in vocal cord morphology recovery was significant (χ²=8.689, P=0.013). The symptoms of hoarseness improved after 12 weeks. The differences between pre and post operative of G grade, VHI, MPT, fundamental frequency perturbation and amplitude perturbation assessed by GRBAS were significant (P<0.05); postoperative G grade, VHI, MPT, fundamental frequency perturbation and amplitude perturbation were compared between the pepsin-positive group and the pepsin-negative group, and the differences were significant (all P<0.05). Conclusion:The expression of pepsin in vocal polyps is a significant clinical indicator that affects the acoustic effect and morphological recovery of vocal cords after surgery. For patients with positive expression, acid suppression treatment should be strengthened after surgery.

Abstract
PURPOSE Laryngopharyngeal reflux disease (LPRD) is a general term for the reflux of gastroduodenal contents into the laryngopharynx, oropharynx and even the nasopharynx, causing a series of symptoms and signs. Currently, little is known regarding the physiopathology of LPRD, and proton pump inhibitors (PPIs) are the drugs of choice for treatment. Although acid reflux plays a critical role in LPRD, PPIs fail to relieve symptoms in up to 40% of patients with LPRD. The influence of other reflux substances on LPRD, including pepsin, bile acid, and trypsin, has received increasing attention. Clarification of the substances involved in LPRD is the basis for LPRD treatment. METHODS A review of the effects of acids, pepsin, bile acids, and trypsin on laryngopharyngeal reflux diseases was conducted in PubMed. RESULTS Different reflux substances have different effects on LPRD, which will cause various symptoms, inflammatory diseases and neoplastic diseases of the laryngopharynx. For LPRD caused by different reflux substances, 24-h multichannel intraluminal impedance combined with pH-metry (MII-pH), salivary pepsin, bile acid and other tests should be established so that different drugs and treatment courses can be used to provide patients with more personalized treatment plans. CONCLUSION This article summarizes the research progress of different reflux substances on the pathogenesis, detection index and treatment of LPRD and lays a theoretical foundation to develop target drugs and clinical diagnosis and treatment.

Abstract
BACKGROUND Dry eye disease (DED) is a common disorder, accounting for up to 35% of the general population. Therefore, we hypothesized that laryngopharyngeal reflux (LPR), inducing refluxate rising into airways, may involve the ocular surface and may either induce or worsen DED. AIM To investigate the prevalence and relevance of suspected LPR in DED patients and subjects with refractive problems (RP) without DED, they were defined as non-dry eye group (NEG) in clinical practice. METHODS This retrospective study included consecutive patients evaluated because of dry eye-like symptoms at eight tertiary ophthalmological clinics. Parameters included reflux symptom index (RSI), ocular surface disease index (OSDI), symptom assessment in dry eye (SANDE) for frequency and severity, Schirmer test, tear break-up time (BUT), and Oxford grading. RESULTS The study included 245 subjects (72.5% females; mean age 56.3 years), 152 DED patients, and 93 sex- and age-matched NEG subjects. Pathological RSI (score>13) was detected in 80 subjects (32.6%); 68 (85%) with DED and 12 (15%) CG (OR = 8; p < .0001). In NEG, pathological RSI was associated with higher SANDE (Frequency and Severity), OSDI, and Schirmer scores (OR = 16.36; 14.51; 12.54; and 7.22, respectively. In DED patients, pathological RSI was associated with higher OSDI values (OR = 8.75). CONCLUSION Patients with DED are at eight times higher risk for having pathological RSI than NEG patients. Moreover, pathological RSI was associated with more severe ocular symptoms both in DED and non-DED patients. The role of LPR in definite DED patients remains to be clarified, but this condition deserves to be investigated in managing patients with DED symptoms.

Abstract
The association of human papillomavirus (HPV) in laryngeal malignancies is largely known. This study evaluated the association between HPV and benign laryngeal lesions and also the role of smoking and alcohol consumption in increasing the prevalence of HPV in such benign lesions. Seventy-eight specimens of benign laryngeal lesions including 26 polyps, 26 dysplasia, and 26 other lesions such as nodules and cysts were enrolled in this study. Polymerase chain reaction (PCR) technique was used to detect HPV DNA in the tissues. The role of smoking and alcohol consumption in the prevalence of HPV was also evaluated through appropriate statistical tests. This study showed that the prevalence of HPV in benign laryngeal lesions was not statistically significant. The Cohen's effect size for comparing polyps vs. other lesions was nearly 0.7, indicating that HPV prevalence in laryngeal polyps may be clinically meaningful. Another finding in our study is the role of smoking in increasing the HPV prevalence in laryngeal polyps (P = 0.034). In benign laryngeal polyps, HPV prevalence may be clinically important. Smoking acts as a co-factor to induce HPV infection in laryngeal polyps in our study.

Abstract
The aim of this study is to explore the relationship between gastroesophageal reflux disease (GERD) and vocal fold polyps (VFPs).This is a Case-Control study and was performed with the help of The Second Affiliated Hospital of Chongqing Medical University.Twenty-seven patients with VFP and 20 controls without VFP were recruited between May and October 2018. All the subjects underwent a saliva pepsin test, completed the GerdQ questionnaire and 24-hour multichannel intraluminal impedance with pH (24-h MII-pH) monitoring. Twenty-five resected VFP specimens were examined with immunohistochemical (IHC) and double immunofluorescence (IF) staining.The incidence of GERD in the VFP group was significantly higher than that in the control group (P = .003). Patients with VFP had significantly higher GerdQ scores, pepsin concentrations, and pepsin-positive rates (P < .05). Moreover, the number of proximal and upright reflux events was significantly higher in the VFP group (P < .05). The pepsin concentration in saliva showed a significant positive correlation with the pepsin levels in tissues (r2 = 0.50, P = .011). Pepsin and TGF-β1-positive cells were colocalized with CD45RO-positive cells. IHC staining showed that the majority of VFP patients had a positive expression of pepsin (20/25, 80%) and pepsin-positive cells were found in both the squamous epithelium and mesenchymal tissues. IHC staining of TGF-β1 in VFP revealed findings similar to those of pepsin staining.GERD is an important risk factor for VFP. Pepsin may promote the aggregation of immune cells, increase the local cytokines, and promote inflammatory reaction, suggesting a potential new pathogenesis for VFP. The saliva pepsin test is a reliable method for GERD diagnosis.

Involvement of Laryngopharyngeal Reflux in Ocular Diseases: A State-of-the-Art Review. J Voice 2021:S0892-1997(21)00106-5.

Abstract
BACKGROUND Laryngopharyngeal reflux-associated symptoms embrace a wide variety of head and neck manifestations. Its participation in eye disorders has recently been postulated, and there is currently no consensus in this regard. The aim of this manuscript is to review the role of reflux in the development of ocular signs and symptoms, and its physio-pathological mechanisms. METHODS A systematic approach based on the preferred reporting Items for a systematic review and meta-analysis checklist with a modified population, intervention, comparison, and outcome framework was used to structure the review process of studies that evaluated the possible association, with clear diagnostic methods, of laryngopharyngeal reflux and ocular signs and symptoms. Search was conducted in different indexed databases (PubMed/MEDLINE, the Cochrane Library, Scielo and Web of Science) and through the meta-searcher Trip Database with the keywords: reflux, laryngitis, laryngopharyngeal, gastroesophageal, ocular, eye, symptoms, signs, conjunctivitis, keratitis, dacryocystitis, dry eye. RESULTS Seven studies met the inclusion criteria, in which the primary acquired nasolacrimal duct obstruction and the ocular surface disease were evaluated. The local increase of eye pepsin concentration (>2.5 ng/mL) may affect ocular surface though its direct proteolytic activity and the local expression of proinflammatory cytokines. The H. Pylori, with a similar mechanism to reach the lacrimonasal duct, would be associated with the release of proinflammatory and vasoactive substances that would lead to a mucosa injury and chronic inflammation. Ocular Surface Disease Index seems to correlate directly with the reflux severity, with cut-off of 41.67 score as predictor for disease. DISCUSSION The role of laryngopharyngeal reflux in the development of ocular disorders has not yet been demonstrated and data are limited and heterogeneous. It seems theoretically conceivable that pepsin may reach lachrymal duct area through hypopharyngeal-nasal gaseous reflux events. Future studies using objective testing for diagnosis and pepsin detection into the tear and nasal mucosa are needed in order to explore this potential relationship.

Abstract
Primary laryngeal epithelial cells are essential to exploring the
mechanisms of laryngeal and voice disorders; however, they are
difficult to study and apply because of their limited life span. The
purpose of this study was to develop a stable and reliable in
vitro model for the comprehensive study of the
pathogenesis of laryngeal and voice diseases. The pLVTHM-Bmi1 plasmid
was constructed and used to immortalize primary laryngeal epithelial
cells by lentiviral infection. The expressions of Bmi1, human
telomerase reverse transcriptase (hTERT), p53, and pRB pathway
proteins were detected by western blotting. Functional characteristics
of the immortalized cell lines were verified by cell senescence
β-galactosidase staining, 5-ethynyl-2′-deoxyuridine cell proliferation
test, and flow cytometry. We successfully introduced Bmi into human
subglottic (hSG) cells and human ventricle (hV) cells. Both the human
immortalized subglottic Bmi1 (hSG-Bmi1) cell line and the human
immortalized ventricle Bmi1 (hV-Bmi1) cell line maintained normal
epithelial morphology and divided successfully after more than 20
culture passages. As Bmi1 was overexpressed in these cells, the
expression of human telomerase reverse transcriptase (hTERT) and
phosphorylated Rb increased while p16 and p21 decreased. Following
Bmi1-mediated immortalization, cell senescence decreased
significantly, and cell proliferation was accelerated. Tumor formation
was not observed for hSG, hV, or hSG-Bmi1, and hV-Bmi1 cells in nude
mice. hSG-Bmi1 cells dominated by stratified squamous epithelium and
hV-Bmi1 cells dominated by columnar cells were established. The new
cell lines lay a foundation for the study of the pathogenic mechanisms
of laryngeal and voice diseases.

Abstract
The upper aerodigestive tract (UAT) is the first line of defense against environmental stresses such as antigens, microbes, inhalants, foods, etc., and mucins, intracellular junctions, epithelial cells, and immune cells are the major constituents of this defensive mucosal barrier. Laryngopharyngeal reflux (LPR) is recognized as an independent risk factor for UAT mucosal disorders, and in this review, we describe the components and functions of the mucosal barrier and the results of LPR-induced mucosal inflammation in the UAT. We discuss the interactions between the refluxate and the mucosal components and the mechanisms through which these damaging events disrupt and alter the mucosal barriers. In addition, we discuss the dynamic alterations in the mucosal barrier that might be potential therapeutic targets for LPR-induced disorders.

Abstract
PURPOSE This study aimed to evaluate if laryngopharyngeal reflux (LPR) plays a role as a risk factor for vocal fold polyps (VFPs), and if pepsin is associated with higher oxidative DNA damage of VFPs in the presence of LPR. METHODS Thirty patients with VFPs were recruited between 2017 and 2018. Prior to surgery, a laryngoscopy was performed on all subjects to evaluate VFPs. Polyp tissue and saliva samples were obtained scrupulously. Hematoxylin-eosin staining was performed for pathologic analysis. Immunohistochemistry and ELISA were used to detect pepsin in tissue and saliva of VFP patients. 8-OHdG and p-H2AX expression was detected to measure oxidative DNA damage in tissue. DNA damage was investigated in human immortalized laryngeal epithelial cells exposed to pepsin. RESULTS The pepsin concentration in saliva was significantly higher (t = 2.38, P = .024) in the pepsin positive group. There was no significant difference in pepsin expression at different sites and pathological subtypes of VFPs. The levels of 8-OHdG and p-H2AX were significantly higher in the pepsin positive group and positively correlated with the tissue expression of pepsin. The concentration of pepsin in saliva also showed a significant correlation with 8-OHdG levels. Expression of 8-OHdG and p-H2AX, and tail moment of the comet assay were elevated in human immortalized laryngeal epithelial cells following treatment with pepsin. CONCLUSION Patients with VFPs have higher levels of oxidative DNA damage in the presence of pepsin reflux. Pepsin may induce DNA damage in laryngeal epithelial cells and participate in the pathogenesis of VFPs.

Abstract
OBJECTIVES Laryngeal dysplasia (LD) is a precancerous lesion of the larynx. In this study, the laryngeal tissue of patients with laryngeal dysplasia was taken as the research object, and the aetiology of reflux was analysed. METHOD Patients with laryngeal dysplasia after surgery were selected as our subjects. The levels of pepsin, enterokinase and bilirubin in laryngeal tissue samples of the two groups were detected by immunohistochemical method. RESULTS The OR values (95% CI) of pepsin, enterokinase and bilirubin were 0.67 (0.19-2.36), 0.80 (0.22-2.98) and 1.33 (0.30-5.96), respectively, in the univariate analysis. Besides, in the multivariate analysis, the OR values (95% CI) of pepsin, enterokinase and bilirubin were 0.57 (0.14-2.30), 0.73 (0.18-2.92) and 1.40 (0.30-6.53), respectively. CONCLUSION Larger sample size should be applied to prospective studies on whether reflux is a risk factor for laryngeal cancer.

Abstract
Background: patients with laryngopharyngeal reflux (LPR) showed detectable levels of tear pepsin that explain the nasolacrimal obstruction. The purpose of this study was to determine whether patients with LPR show ocular surface changes and to investigate the relationship between lacrimal pepsin concentration and ocular alterations. Methods: Fifty patients with positive endoscopic signs for LPR and an equal or higher score of 13 and 7 for Reflux Symptom Index and Reflux Finding Score were enrolled. Twenty healthy patients with no reflux disease and dry eye were included as the control group. After evaluation of ocular discomfort symptoms, the tear break-up time test, corneal staining, and tear sampling were performed. Tear pepsin levels were measured using Pep-testTM kit. Results: Patients with LPR showed ocular surface changes including epithelial damage (48%) and impairment of lacrimal function (72%). Tear pepsin levels were detectable in 32 out of 50 (64%) patients with LPR (mean ± SD: 55.4 ± 67.5 ng/mL) and in none of the control subjects. Most of the LPR patients complained of ocular discomfort symptoms, including itching (38%), redness (56%), or foreign body sensation (40%). Tear pepsin levels were significantly correlated with the severity of LPR disease and with ocular surface changes. Conclusions: A multidisciplinary approach, including ophthalmological evaluation, should be considered in order to improve the management of patients with LPR.

Abstract
OBJECTIVE To measure pepsin expression in patients with vocal fold leukoplakia and elucidate its clinical significance. STUDY DESIGN Retrospective analysis of pathologic archive specimens. SETTING Affiliated university hospital. SUBJECTS AND METHODS The study included 45 patients with vocal fold leukoplakia and 19 with vocal fold polyps who underwent surgical treatment between December 2013 and July 2016. Masses were detected on both vocal cords in 5 patients with vocal fold leukoplakia and in 1 patient with vocal fold polyps. Immunohistochemistry was used to assess pepsin expression. In addition, the relationship of pepsin expression level with clinical characteristics of vocal fold leukoplakia was assessed. RESULTS The rate of pepsin expression was high in the polyp group (75%) and the leukoplakia group (68%); however, the difference between groups was not significant (P > .05). Pepsin expression significantly increased according to grade of dysplasia (mild, 57.1%; moderate, 88.9%; severe, 100.0%; P = .034). Similarly, the percentage of lesions that exhibited strongly positive pepsin expression increased with the grade of dysplasia (mild, 37.1%; moderate, 66.7%; severe, 100.0%; P = .005). The leukoplakia recurrence rate was higher in patients with positive pepsin expression than in patients with negative pepsin expression but without a significant difference (P > .05). CONCLUSION Our study suggests that pepsin was associated with the grade of dysplasia of vocal cord leukoplakia. Further investigation with appropriate control groups and controlling for other risk factors, such as smoking or alcohol consumption, is needed.

Abstract
Benign laryngeal lesions are often the result of phonotraumatic forces on the vocal folds and thus classically are treated with a combination of voice therapy and phonomicrosurgical techniques to minimize inadvertent additional trauma. Newer management strategies expand on these techniques with the use of the pKTP laser as well as intralesional injections, both in the operating room and in the awake outpatient setting.

Abstract
OBJECTIVE To review the current literature about the epidemiology, clinical presentation, diagnosis, and treatment of laryngopharyngeal reflux (LPR). DATA SOURCES PubMed, Cochrane Library, and Scopus. METHODS A comprehensive review of the literature on LPR epidemiology, clinical presentation, diagnosis, and treatment was conducted. Using the PRISMA statement, 3 authors selected relevant publications to provide a critical analysis of the literature. CONCLUSIONS The important heterogeneity across studies in LPR diagnosis continues to make it difficult to summarize a single body of thought. Controversies persist concerning epidemiology, clinical presentation, diagnosis, and treatment. No recent epidemiologic study exists regarding prevalence and incidence with the use of objective diagnostic tools. There is no survey that evaluates the prevalence of symptoms and signs on a large number of patients with confirmed LPR. Regarding diagnosis, an increasing number of authors used multichannel intraluminal impedance-pH monitoring, although there is no consensus regarding standardization of the diagnostic criteria. The efficiency of proton pump inhibitor (PPI) therapy remains poorly demonstrated and misevaluated by incomplete clinical tools that do not take into consideration many symptoms and extralaryngeal findings. Despite the recent advances in knowledge about nonacid LPR, treatment protocols based on PPIs do not seem to have evolved. IMPLICATIONS FOR PRACTICE The development of multichannel intraluminal impedance-pH monitoring and pepsin and bile salt detection should be considered for the establishment of a multiparameter diagnostic approach. LPR treatment should evolve to a more personalized regimen, including diet, PPIs, alginate, and magaldrate according to individual patient characteristics. Multicenter international studies with a standardized protocol could improve scientific knowledge about LPR.

Abstract
Introduction Vocal fold polyps are one of the most frequent benign laryngeal lesions, impacting the quality of life of those affected by them, primarily the vocal production. Despite being a well-established therapy in conjunction with surgery, speech therapy alone may also be effective in treating these lesions. As such, otolaryngologists and speech therapists need updated bibliographic knowledge on the issue. Objective To describe the literature findings on vocal fold polyps that discuss prevalence, etiology, histology, physiopathology, vocal characteristics or treatment. Data Synthesis The present study is a review article based on a bibliographic search using platforms, databases and search engines, with no restrictions on means of publication, methodological quality or language. All the articles on vocal fold polyps pertaining to the object of study published in the past 15 years were included. Among the characteristics investigated, the most discussed were prevalence of men, smoking as an etiological cofactor, the possibility of histological differentiation from vocal nodules, the relationship with cover minor structural alterations, and the indication and effectiveness of different treatment options. Conclusion Despite the discrepancies found in the present literature review on vocal fold polyps, there has been a notable scientific progress in the otolaryngologic techniques and in the effectiveness of speech therapy as initial treatment, with direct and indirect techniques, corroborating the need for scientific investigation of the issue.

Abstract
The purpose of this review is to outline the recent developments in the field of extraesophageal reflux disease and provide clinically relevant recommendations. The recommendations outlined in this review are based on expert opinion and on relevant publications from PubMed and EMbase. The Clinical Practice Updates Committee of the American Gastroenterological Association proposes the following recommendations: Best Practice Advice 1: The role of a gastroenterologist in patients referred for evaluation of suspected extra esophageal symptom is to assess for gastroesophageal etiologies that could contribute to the presenting symptoms. Best Practice Advice 2: Non-GI evaluations by ENT, pulmonary and/or allergy are essential and often should be performed initially in most patients as the cause of the extraesophageal symptom is commonly multifactorial or not esophageal in origin. Best Practice Advice 3: Empiric therapy with aggressive acid suppression for 6-8 weeks with special focus on response of the extraesophageal symptoms can help in assessing association between reflux and extraesophageal symptoms. Best Practice Advice 4: No single testing methodology exists to definitively identify reflux as the etiology for the suspected extra esophageal symptoms. Best Practice Advice 5: Constellation of patient presentation, diagnostic test results and response to therapy should be employed in the determination of reflux as a possible etiology in extra esophageal symptoms. Best Practice Advice 6: Testing may need to be off or on proton pump inhibitor (PPI) therapy depending on patients' presenting demographics and symptoms in assessing the likelihood of abnormal gastroesophageal reflux. A. On therapy testing may be considered in those with high probability of baseline reflux (those with previous esophagitis, Barrett's esophagus or abnormal pH). B. Off therapy testing may be considered in those with low probability of baseline reflux with the goal of identifying moderate to severe reflux at baseline. Best Practice Advice 7: Lack of response to aggressive acid suppressive therapy combined with normal pH testing off therapy or impedance-pH testing on therapy significantly reduces the likelihood that reflux is a contributing etiology in presenting extraesophageal symptoms. Best Practice Advice 8: Surgical fundoplication is discouraged in those with extra esophageal reflux symptoms unresponsive to aggressive PPI therapy. Best Practice Advice 9: Fundoplication should only be considered in those with a mechanical defect (e.g., hiatal hernia), moderate to severe reflux at baseline off PPI therapy who have continued reflux despite PPI therapy and have failed more conservative non-GI treatments.

Abstract
BACKGROUND Several studies have indicated the larynx as possible Helicobacter pylori (H. pylori) reservoirs. This study explored the association between H. pylori and vocal fold leukoplakia. METHODS The case-control study involved 51 patients with vocal fold leukoplakia and 35 control patients with vocal polyps. Helicobacter pylori was detected in tissues by the rapid urease test, nested polymerase chain reaction (PCR), and single-step PCR. The H. pylori-specific immunoglobulin antibodies were detected in plasma by enzyme-linked immunosorbent assay (ELISA). RESULTS Helicobacter pylori-positive rate of vocal fold leukoplakia and vocal polyps was 23.5% versus 11.4% (P = .157), 37.2% versus 14.3% (P = .020), 27.5% versus 8.6% (P = .031), and 70.6% versus 68.6% (P = .841) detected by rapid urease test, nested PCR, single-step PCR, and ELISA, respectively. Regression analysis indicated that H. pylori infection (P = .044) was the independent risk factor for vocal fold leukoplakia. CONCLUSION Helicobacter pylori infection exists in the larynx and may be associated with vocal fold leukoplakia.

Abstract
Background None of current diagnostic methods has been proven to be a reliable tool for gastro-esophageal reflux disease (GERD). Pepsin in saliva has been proposed as a promising diagnostic biomarker for gastro-esophageal reflux. We aimed to determine the diagnostic value of salivary pepsin detection for GERD. Methods Two hundred and fifty patients with symptoms suggestive of GERD and 35 asymptomatic healthy volunteers provided saliva on morning waking, after lunch and dinner for pepsin determination using the Peptest lateral flow device. All patients underwent 24-h multichannel intraluminal impedance pH (24-h MII-pH) monitoring and upper gastrointestinal endoscopy. Based on 24-h MII-pH and endoscopy study, patients were defined as GERD (abnormal MII-pH results and/or reflux esophagitis) and non-GERD otherwise. Results Patients with GERD had a higher prevalence of pepsin in saliva and higher pepsin concentration than patients with non-GERD and healthy controls (P < 0.001 for all). The pepsin test had a sensitivity of 73% and a specificity of 88.3% for diagnosing GERD using the optimal cut-off value of 76 ng/mL. Postprandial saliva samples collected when the symptoms occurred had a more powerful ability to identify GERD. Conclusions Salivary pepsin test had moderate diagnostic value for GERD. It may be a promising tool to replace the use of currently invasive tools with advantages of non-invasive, easy to perform and cost effective.
