Open Med (Wars) 2023; 18:20230791. [PMID: 37840752 PMCID: PMC10571518 DOI: 10.1515/med-2023-0791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/04/2023] [Accepted: 08/09/2023] [Indexed: 10/17/2023] Open
Abstract
The purpose of this study was to examine the characteristics of proximal and distal gastroesophageal reflux in patients with gastroesophageal reflux disorder and analyze their clinical symptoms. A total of 67 patients with typical esophageal symptoms were selected for this study. All participants completed the reflux disease questionnaire and a questionnaire survey of extraesophageal symptoms. Diagnosis was made using a 24-h impedance-pH detection and proton pump inhibitor. The results showed that the proximal reflux group had a higher number of acid reflux episodes compared to the distal reflux group (P < 0.05). Similarly, the proximal reflux group also had a higher number of gas reflux episodes compared to the distal reflux group (P < 0.05). On the other hand, the distal reflux group had a higher number of mixed reflux episodes compared to the proximal reflux group (P < 0.05). These differences were statistically significant. This study revealed that acid reflux and gas reflux were more predominant in the proximal reflux group, while mixed reflux was more predominant in the distal reflux group.

Meta-analysis of Proton Pump Inhibitors in the Treatment of Pharyngeal Reflux Disease. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:9105814. [PMID: 35912160 PMCID: PMC9334091 DOI: 10.1155/2022/9105814] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 06/24/2022] [Accepted: 06/28/2022] [Indexed: 01/26/2023]
Abstract
The present study aimed to examine the safety and healing effects of proton pump inhibitors (PPIs) in people with laryngopharyngeal reflux disease (LPRD). To find all relevant studies published before April 1, 2022, we searched the PubMed, Embase, Web of Science, Clinical Trials, Cochrane Library, CNKI, and Wanfang databases. For SLE, we looked for all randomized controlled clinical trials related to PPIs versus placebo-controlled treatment of LPRD. Overall efficiency, reflux symptom index (RSI), reflux finding score (RFS), improvement in cough and hoarseness, and adverse reactions were compared using the Review Manager 5.3. Using the reflux symptom index (RSI) as an outcome indicator for efficacy assessment, the PPI group showed significant improvement compared with the placebo group [MD = 3.35, 95% CI (1.34, 5.37, P < 0.05)]. In terms of overall efficacy, the PPI group showed effectiveness, but its efficacy was not statistically significantly dissimilar from that of the placebo group [OR = 1.62, 95% CI (0.89, 2.95), P > 0.05].

Abstract
Introduction Laryngopharyngeal reflux (LPR) is a prevalent condition in outpatients visiting the otorhinolaryngological clinic, with many controversies regarding its diagnosis and follow-up. Therefore, there is a need for clinical instruments that can diagnose individuals and monitor the results of their treatment. Objective To evaluate the applicability of the scores translated and adapted to Brazilian Portuguese: Reflux Symptom Index (RSI) and Endolaryngeal Reflux Findings Scale (ERFS), as instruments for post-treatment follow-up of LPR. Method A total of 35 individuals with atypical symptoms of gastroesophageal reflux disease and with an objective diagnosis of LPR, confirmed by high digestive endoscopy and 24-hour esophageal pH-metry dual probe test were submitted to the RSI and ERFS questionnaires, used in the pre- and post-treatment of 90 days with a Proton Pump Inhibitor. Result The evaluation of RSI and ERFS in the pre- and post-treatment showed a reduction in the results of the two scores, with a higher drop in the RSI ( p < 0.001) than in the ERFS ( p = 0.014). Although there was an improvement in the values in 23.9% of the individuals in the ERFS, there was no change in the category ( p = 0.057), different from the RSI ( p < 0.001), where there was a 67.4% improvement in values, as well as change in category (score went from positive to negative). There was a correlation between RSI and ERFS, moderate in the pretreatment and strong in the post-treatment. Conclusion The RSI and ERFS scores, when translated and adapted for Brazilian Portuguese and applied simultaneously, can be considered a good tool for post-treatment LPR follow-up.

Abstract
OBJECTIVE This study aimed to determine the relationship between laryngopharyngeal reflux and dietary modification. METHODS A systematic review was conducted. The data sources for the study were PubMed, Embase, Cochrane Library and Web of Science. Articles were independently extracted by two authors according to inclusion and exclusion criteria. The outcome focus was laryngopharyngeal reflux improvement through diet or dietary behaviour. RESULTS Of the 372 studies identified, 7 met our inclusion criteria. In these seven studies, laryngopharyngeal reflux symptoms improved following dietary modifications. However, the studies did not present the independent effect of each dietary factor on laryngopharyngeal reflux. Moreover, only one of the seven studies had a randomised controlled study design. CONCLUSION The reference studies of dietary modification for laryngopharyngeal reflux patients are not sufficient to provide recommendations.

Abstract
Sjögren syndrome was chosen as a clinical model to study acinar salivary deficiencies in the development of laryngopharyngeal reflux (LPR). The objective of this prospective cohort study was to compare salivary epidermal growth factor (EGF) concentrations of patients with Sjögren syndrome with and without LPR and gastroesophageal reflux disease (GERD) with normal controls. LPR was diagnosed with positive scores on the Reflux Symptom Index and Reflux and Reflux Finding Score, corroborated by esophagogastroduodenoscopy and/or 24-hour pH-metry. Salivary EGF concentrations of both unstimulated and mechanically stimulated saliva were established using enzyme-linked immunosorbent assay, and the significance level was set at 95%. Twenty-one patients and 19 controls were studied. All patients had LPR and 60% also had GERD. The mean salivary EGF concentration of unstimulated and stimulated saliva in the control group was 1,751.37 pg/ml and 544.76 pg/ml, respectively. Unstimulated and stimulated salivary EGF concentrations in the study group were 2,534.65 pg/ml and 920.69 pg/ml, respectively. These differences were not statistically significant. Body mass index, presence of erosive esophagitis, or severity of hyposalivation did not significantly influence salivary EGF concentrations. LPR and GERD are highly prevalent in patients with Sjögren syndrome. Unlike previous studies in which significant EGF deficiencies were found in patients with reflux laryngitis and GERD, patients with Sjögren syndrome seem to have reflux caused by a decrease in clearance capacity and not in specific salivary components.

Abstract
Introduction Saliva plays a key role in the homeostasis of the digestive tract, through its inorganic components and its protein growth factors. Sjögren's syndrome patients have a higher prevalence of gastroesophageal reflux disease and laryngopharyngeal reflux. Decreased salivary transforming growth factor alpha levels were observed in dyspeptic patients, but there have been no studies in patients with Sjögren's syndrome and laryngopharyngeal reflux. Objective To compare the salivary transforming growth factor alpha levels of patients with Sjögren's syndrome and laryngopharyngeal reflux to those of healthy controls. Methods This is a prospective controlled study. Twelve patients with Sjögren's syndrome and laryngopharyngeal reflux and 11 controls were prospectively evaluated. Spontaneous and stimulated saliva samples were obtained to establish salivary transforming growth factor alpha concentrations. Results The salivary transforming growth factor alpha levels of patients were significantly higher than those of healthy controls. Five patients with laryngopharyngeal reflux also had erosive esophagitis; their salivary transforming growth factor alpha levels were comparable to controls. Conclusion Salivary transforming growth factor alpha level was significantly higher in patients with Sjögren's syndrome and laryngopharyngeal reflux when compared to the control group.

Abstract
Introdução A apneia obstrutiva do sono (AOS) é causada por episódios recorrentes de obstrução total ou parcial da via aérea superior com duração superior a 10 segundos durante o sono. Refluxo faringolaríngeo (RFL) é uma variante da doença do refluxo gastroesofágico que afeta a laringe e a faringe. Objetivos Avaliar a influência da obesidade na relação entre RFL e AOS em pacientes com SAOS. Materiais e métodos Estudo observacional transversal retrospectivo. Foram revisados protocolos de atendimento de pacientes com AOS que incluem questionários validados para RFL como Reflux Sympton Index (RSI) e Reflux Finding Score (RSI), nasolaringofibroscopia e polissonografia. Resultados Cento e cinco pacientes foram divididos em grupo de obesos (39 pacientes) e não obesos (66 pacientes). Na avaliação das médias do RSI o grupo de não obesos foi semelhante entre pacientes com AOS leve (11,96) e moderada (11,43). No grupo de obesos a média do RSI foi de 6,7 em pacientes com AOS leve e de 11,53 em pacientes com AOS moderada a grave (p < 0,05). Discussão O subgrupo de pacientes com AOS e RFL apresenta vários fatores que promovem a inflamação da via aérea superior. Pacientes com AOS devem ser pesquisados e tratados quanto a RFL, aumentando a qualidade de vida. Conclusão O RFL e a AOS se correlacionam positivamente em pacientes obesos. © 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-FaciaL Publicado por Elsevier Editora Ltda.

Abstract
Objectives: The diagnosis of laryngopharyngeal reflux (LPR) is controversial. There is no correlation between the number of reflux episodes and the severity of the inflammatory response at the esophagus or the laryngopharyngeal segment. Some authors have suggested that decreased salivary epidermal growth factor (EGF) concentrations in patients with gastroesophageal reflux disease and LPR point to a breakdown in the local defenses. Our objective was to establish whether treatment of the disease influences low salivary EGF concentrations. Methods: The spontaneous whole saliva of 20 adults with LPR was sampled at a tertiary teaching hospital before and after a 16-week course of full-dose proton pump inhibitor and compared to that of 12 healthy controls. Salivary EGF concentrations were established with a commercially available enzyme-linked immunosorbent assay kit. Results: Although the mean salivary EGF concentrations were higher before treatment than after treatment and control of the disease (25,083 versus 19,359 pg/mL), this difference was not statistically significant (p = 0.065). The mean salivary EGF concentration of healthy control subjects was significantly higher (54,509 pg/mL; p < 0.0001). Conclusions: Both before and after treatment, patients with reflux laryngitis present lower salivary EGF concentrations than healthy control subjects, suggesting a primary deficit in their protective mechanisms.

Abstract
The pathophysiology of chronic cough and its association with dsymotility and laryngopharyngeal reflux remains unclear. This study applied high-resolution manometry (HRM) to obtain a detailed evaluation of pharyngeal and esophageal motility in chronic cough patients with and without a positive reflux-cough symptom association probability (SAP). Retrospective analysis of 66 consecutive patients referred for investigation of chronic cough was performed. Thirty-four (52%) were eligible for inclusion (age 55 [19-77], 62% female). HRM (ManoScan 360, Given/Sierra Scientific Instruments, Mountain View, CA) with 10 water swallows was performed followed by a 24-hour ambulatory pH monitoring. Of this group, 21 (62%) patients had negative reflux-cough SAP (group A) and 13 (38%) had positive SAP (group B). Results from 23 healthy controls were available for comparison (group C). Detailed analysis revealed considerable heterogeneity. A small number of patients had pathological upper esophageal sphincter (UES) function (n=9) or esophageal dysmotility (n=1). The overall baseline UES pressure was similar, but average UES residual pressure was higher in groups A and B than in control group C (-0.2 and -0.8mmHg vs. -5.4mmHg; P<0.018 and P<0.005). The percentage of primary peristaltic contractions was lower in group B than in groups A and C (56% vs. 79% and 87%; P=0.03 and P<0.002). Additionally, intrabolus pressure at the lower esophageal sphincter was higher in group B than in group C (15.5 vs. 8.9; P=0.024). HRM revealed changes to UES and esophageal motility in patients with chronic cough that are associated with impaired bolus clearance. These changes were most marked in group B patients with a positive reflux-cough symptom association.

Abstract
OBJETIVO: relacionar o Índice de Sintomas do Refluxo Faringo-Laríngeo - ISRFL com os principais sintomas do refluxo gastresofágico - RGE (azia/queimação e dor retroesternal), com o nível de uso da voz e com uma triagem vocal. MÉTODO: participaram deste estudo 179 voluntários maiores de 18 anos, 107 mulheres e 72 homens, classificados em dois grupos de acordo com o escore total do ISRFL, grupo positivo (escore total igual ou maior a 13 pontos) e negativo (abaixo deste). Os participantes foram questionados sobre a presença dos sinais característicos do refluxo gastresofágico (azia/queimação e/ou dor retroesternal), sobre a demanda de uso da voz (baixa/alta demanda) e submetidos à triagem vocal durante a entrevista. RESULTADOS: quanto ao ISRFL, 35 (19,6%) indivíduos compuseram o grupo positivo (escore médio de 20) e 144 (80,4%) o grupo negativo (média de 4,34 pontos). Os sintomas característicos do RGE foram maiores no grupo positivo: azia/queimação em 54,2% (19) verso 30,5% (44), dor retroesternal em 51,4% (18) verso 20,1% (29), sendo que 74,3% dos indivíduos do grupo positivo e apenas 43,1% do negativo apresentaram algum dos sintomas. Quanto à triagem vocal, 37,1% do grupo positivo e 13% do negativo falharam. Não houve diferença de demanda vocal auto-relatada entre os grupos. Foi encontrada associação estatística entre IRFL positivo, os sintomas de refluxo gastresofágico e fracasso na triagem vocal (p< 0,001). Não houve associação quanto ao uso da voz. CONCLUSÃO: o ISRFL positivo pode estar relacionado com os sinais do RGE e com a alteração na qualidade vocal percebida em triagem.

Abstract
BACKGROUND In recent years, laryngopharyngeal reflux (LPR) in children has been taken into consideration. OBJECTIVE The aim of this study was to assess the laryngoscopic findings in children diagnosed LPR and/or gastro-oesophageal reflux (GERD). METHODS The findings of 49 patients with at least one or more respiratory complaint such as chronic cough, wheezing, hoarseness, recurrent laryngitis, and throat clearing/postnasal discharge suggesting LPR were evaluated retrospectively. The diagnosis of LPR+GERD or GERD was done by the clinical history and 24 h double-probe pH monitoring and/or scintigraphy. RESULTS Thirty eight out of 49 patients examined by laryngoscopy underwent 24 h double-probe pH monitoring and/or scintigraphy. Thirty of them were diagnosed as LPR+GERD or GERD by any test positivity. Twelve of 30 patients diagnosed with LPR+GERD or GERD had a positive laryngeal finding on the examination of fibre optic laryngoscopy. The most common finding with eight cases was arytenoid erythema A sensitivity of 40% and specificity of 50% for the laryngoscopy in the diagnosis of LPR/GERD were found. CONCLUSION In children with unexplained respiratory symptoms, laryngopharyngeal reflux should be suspected. Therefore, until enough data on this issue in the literature accumulates, the history and the laboratory findings of the patients obtained from various techniques to document paediatric LPR should be evaluated together.

Abstract
Saliva is one of the components for the digestive homeostasis. Recent studies have shown that patients with laryngopharyngeal reflux (LPR) present a drop in salivary pH. Patients with Sjögren´s syndrome (SS) are a potential clinical research model for xerostomia and its laryngeal and pharyngeal consequences. The aim was to evaluate the characteristics of saliva of patients with SS and LPR. Methods 19 patients with SS plus LPR, and 12 healthy controls had their saliva studied prospectively for volume and pH. Two salivary samples were obtained from each participant: whole unstimulated saliva(WUS) and whole stimulated saliva(WSS) while chewing parafilm M®. All the participants were females. Results Mean age was 60 years (study group) and 44 years (control). LPR was diagnosed on all 19 subjects. The mean pH of WUS was 7.53 (SS) and 7.57 (controls), raising to 7.87 and 7.83 respectively after stimulation. The mean salivary volume of patients with SS was 1.27 mL (WUS) and 3.78 mL (WSS), whereas controls had a significantly higher salivary volume both before and after stimuli. Conclusion A very high prevalence of LPR was found in patients with SS, which is probably caused by a uniform drop in salivary volume and all its contents, rather than a specific deficiency in its components, as shown previously in patients without SS.

Abstract
The reliability of Nissen fundoplication for the successful treatment of laryngopharyngeal reflux (LPR) symptoms remains in question. The purpose of this study was to assess the effect that antireflux surgery has on a variety of LPR symptoms as well as the patient's perceived success of surgical intervention. A retrospective review of all antireflux surgeries between 1998 and 2008 provided a patient base for a survey in which patients ranked pre- and postoperative LPR symptoms in addition to patient satisfaction with the outcome. Of the 611 patients identified and sent the evaluation forms, 244 responses (40%) were obtained. The percentage of patients with symptom improvement after surgery were: heartburn (90.1%), regurgitation (92.6%), voice fatigue (75.2%), chronic cough (76.3%), choking episodes (83.1%), sore throat (82.9%), lump in throat (77.4%), repetitive throat clearing (72.8%), and adult-onset asthma (59.6%). Twenty per cent with repetitive throat clearing and 30 per cent with adult-onset asthma had no improvement in symptoms. Eighty-one per cent considered surgery to be a success. Comparison of those who claimed the operation was successful with those who claimed it was not revealed no difference in demographics, primary diagnosis, procedure type, or reflux symptom index score. There was a statistically significant difference in patient-perceived outcome according to the length of time since surgery. More than 88 per cent in the "not successful" group had an operation greater than 4 years prior as compared with only 70 per cent in the "successful" group (P = 0.020). Nissen fundoplication is an effective treatment for most LPR symptoms, although patients with adult-onset asthma and repetitive throat clearing appear to benefit least from surgical intervention.

Abstract
The techniques used in the diagnosis of gastroesophageal reflux disease (GERD) have insufficient specificity and sensitivity in diagnosing laryngopharyngeal reflux (LPR). The purpose of this study was to evaluate the role of esophagogastroduodenoscopy (EGD) and laryngological examination in the diagnosis of LPR. A total of 684 diagnosed GERD and suspected LPR patients were prospectively scored by the reflux finding score (RFS) which was suggested by Koufman. A total of 484 patients with GERD who had RFS ≥ 7 were accepted as having LPR. 248 patients with GERD plus LPR on whom an endoscopic examination was performed were evaluated. As a control group, results from 82 patients with GERD who had RFS <7 were available for comparison. The GERD symptom score (RSS) was counted according to the existence of symptoms (heartburn/regurgitation) and frequency, duration, and severity. The reflux symptom index (RSI) suggested by Belafsky et al. was also evaluated. The relationship between esophageal endoscopic findings, RSS, RFS and RSI was investigated. Mean age was 46 ± 12 (19-80). The mean values of RSS, RFS, and RSI were 18.9 ± 7.7, 10 ± 2.2, 16.6 ± 11.9, respectively. Erosive esophagitis was detected in 75 cases (30%). Hiatus hernia was observed in 32 patients (13%). There was no correlation between RSS and RFS, RSI. The severity of esophagitis did not correlate with the severity of the laryngeal findings. LPR should be suspected when the history and laryngoscopy findings are suggestive of the diagnosis. EGD has no role in the diagnosis of LPR.

Abstract
Laryngopharyngeal Reflux (LPR) is a commonly occurring and recently described clinical entity due to the retrograde flow of gastric contents into the pharynx. It accounts for many symptoms of upper airway including hoarseness, chronic throat irritation and globus sensation. The sensitive laryngeal mucosa is prone to damage by the combination of acid and pepsin. The inflammatory changes that follow are presumed to cause the symptoms and predispose the individual to laryngeal disorders. Diagnosis can usually be made clinically based on symptoms and laryngeal signs but a 24 hour pH metry is essential to establish diagnosis. Treatment centres on lifestyle modifications, vocal hygiene measures and long term use of proton pump inhibitors. Recent research in this field may lead to a better understanding of the pathophysiology of the disease and change the way LPR is managed.

Abstract
The role of proton pump inhibitor in the treatment of laryngopharygneal reflux disease (LPRD) has been advocated, but there has been few reports dealing with large population based on time-related efficacy of rabeprazole. It was designed to assess the efficacy of rabeprazole and to evaluate which symptoms or findings varied significantly as medication sustained. Multiorgan, open-label cohort, prospective observational study was designed. We identified 1,142 patients with LPRD, and enrolled 455 patients, who participated fully in this survey and follow-up observation for 12 weeks. Reflux symptom index (RSI) and reflux finding score (RFS) were used to evaluate therapeutic efficacy. These parameters were evaluated at the 4th, 8th, and 12th weeks, respectively. Valid rate was used to explain improved proportion of patients after medication. The most common symptom was a globus sense in the throat. Posterior commissure hypertrophy was the most frequently encountered laryngoscopic finding. Female patients complained of heartburn and chest pain more than did male patients (P < 0.001), whereas male patients showed ventricular obliteration and erythematous changes more frequently than did female patients (P < 0.001). By RSI evaluation, scores gradually declined. Each item of the RSI improved at every visit (P < 0.001). Total RFS decreased progressively for 12 weeks and similar results were seen when every RFS item was individually examined. The proportion of patients who showed RSI and RFS falling by more than 50% after medication increased gradually as follow-up continued. This trend seemed to be significant (P < 0.001). Side effects of therapy were minimal. Despite the some constraints of an observational study, rabeprazole appeared to improve LPRD symptoms and signs. Prolonged medication at least 3 months may be beneficial to LPRD patients. Long-term medication effects require further evaluation.

Abstract
OBJECTIVE: Pepsin detection in throat sputum has been posited as a reliable biological marker of laryngopharyngeal reflux disease (LPRD). This study was designed to further correlate pepsin concentration with symptoms and signs of LPRD. STUDY DESIGN: Cross-sectional study. SETTING: Nanfang Hospital of Southern Medical University. SUBJECTS AND METHODS: Fifty-six laryngitis patients were divided into a reflux laryngitis group and a chronic laryngitis group based on the reflux symptom index (RSI), reflux finding score (RFS), and proton pump inhibitor treatment for two weeks. Oral and hypopharyngeal secretions from the study patients and from 15 healthy subjects were collected. Thirty-six obstructive sleep apnea (OSA) patients were divided into a mild-moderate group and a severe group by the apnea-hypopnea index (AHI). Bedtime and first-morning oral secretions were collected. Enzyme-linked immunosorbent assay was used to measure the pepsin concentration. RESULTS: In laryngitis patients, the total score of RSI and RFS ( P < 0.05), and the symptoms, including clearing throat often, coughing, and sensing a lump in the throat ( P < 0.006), were more severe in the pepsin-positive group. No significant differences were found between the oral and hypopharyngeal secretions. In OSA, pepsin levels in the first-morning oral secretions were correlated with AHI, mean SaO2, and mini SaO2 ( P < 0.01). However, RSIs were not significantly correlated with these indicators. CONCLUSION: Higher levels of pepsin in sputum were associated with higher RSI and RFS in cases of laryngitis. There was no relationship between pepsin levels and RSI in cases of OSA. There were no differences of pepsin concentration in sputum collection methods or in collection timing.

Abstract
Objectives: We undertook to 1) obtain unequivocal evidence to confirm or rebut our initial observations that pepsin is taken up by hypopharyngeal epithelial cells by receptor-mediated endocytosis, 2) investigate whether uptake of pepsin at pH 7, in nonacidic refluxate, is of pathological significance, and 3) test our hypothesis that inactive but stable pepsin (<pH 8) taken up by hypopharyngeal epithelial cells causes damage by becoming reactivated inside the cell. Methods: Human posterior cricoid biopsy specimens and cultured hypopharyngeal FaDu epithelial cells were used to perform competitive binding studies and to investigate colocalization of pepsin with clathrin, Rab-9, and TRG-46. FaDu cells were exposed to pepsin (both irreversibly and reversibly inactivated) in the presence and absence of wortmannin and dimethyl amiloride and analyzed by electron microscopy, MTT cytotoxicity assay, and Stress and Toxicity SuperArray. Results: Pepsin is unequivocally taken up by hypopharyngeal epithelial cells by receptor-mediated endocytosis. Uptake of pepsin at pH 7, in nonacidic refluxate, causes mitochondrial damage and changes the expression of several genes implicated in stress and toxicity. Irreversible, but not reversible, inhibition of peptic activity prevents these changes. Conclusions: Pepsin, at pH 7, in nonacidic refluxate, causes damage by becoming reactivated inside the cell. Irreversible inhibitors of peptic activity hold promise as a new therapy for reflux.

Abstract
OBJECTIVE Muscle tension dysphonia (MTD) is a clinical and diagnostic term describing a spectrum of disturbed vocal fold behavior caused by increased tension of the (para)laryngeal musculature. Recent knowledge introduced MTD as a bridge between functional and organic disorders. This review addresses the causal and contributing factors of MTD and evaluates the different treatment options. METHODS We searched MEDLINE (Pubmed, 1950-2009) and CENTRAL (The Cochrane Library, Issue 2, 2009). Studies were included if they reviewed the classification of functional dysphonia or the pathophysiology of MTD. Etiology and pathophysiology of MTD and circumlaryngeal manual therapy (CMT) were obligatory based on reviews and prospective cohort studies because randomized controlled trials (RCTs) are nonexisting. Concerning the treatment options of voice therapy and vocal hygiene, selection was based on RCTs and systematic reviews. RESULTS Etiological factors can be categorized into three new subgroups: (1) psychological and/or personality factors, (2) vocal misuse and abuse, and (3) compensation for underlying disease. The effective treatment options for MTD are (1) indirect therapy: vocal hygiene and patient education; (2) direct therapy: voice therapy and CMT; (3) medical treatment; and (4) surgery for secondary organic lesions. CONCLUSIONS MTD is the pathological condition in which an excessive tension of the (para)laryngeal musculature, caused by a diverse number of etiological factors, leads to a disturbed voice. Etiological factors range from psychological/personality disorders and vocal misuse/abuse to compensatory vocal habits in case of laryngopharyngeal reflux, upper airway infections, and organic lesions. MTD needs to be approached in a multidisciplinary setting where close cooperation between a laryngologist and a speech language pathologist is possible.

Abstract
BACKGROUND Randomized, placebo-controlled studies have failed to demonstrate a significant treatment effect for laryngopharyngeal reflux (LPR) using traditional clinical endpoints. We compared the effect of esomeprazole 20 mg twice daily (b.i.d.) vs placebo on voice and acoustic-related measures in patients with LPR. METHODS Patients with LPR underwent endoscopy and pH testing. Subsequently, patients underwent videostroboscopic recordings of the larynx, acoustic voice and speech analysis. A voice use and quality diary and oesophageal symptom diary were completed at baseline. Thereafter, patients were randomized to esomeprazole 20 mg twice daily vs placebo for 3 months. The voice use and quality diary and oesophageal symptom dairy were repeated during the last week of treatment. Videostroboscopy and acoustic voice and speech analysis were also performed at the end of treatment. KEY RESULTS Twenty-four patients were randomized to the esomeprazole group and 17 to the placebo group. There was no significant difference in videostroboscopic reflux finding scores from baseline to post-treatment. Acoustic measures also failed to demonstrate significant differences within the same or between groups, even when a sub-group analysis of patients with endoscopically documented oesophageal inflammation at baseline was performed. Additionally, no significant differences were found between groups when using voice use and quality diary. CONCLUSIONS & INFERENCES Use of more specific laryngeal functional parameters such as voice-related acoustic measures of pitch range, fundamental frequency and intensity also failed to demonstrate a significant response to proton pump inhibitor treatment as compared to placebo in patients with suspected LPR.

Abstract
PURPOSE OF REVIEW Laryngopharyngeal reflux is a widely recognized disorder. Yet, decades after its initial description, debate persists regarding pathophysiology, diagnosis, and treatment. This review addresses current literature on laryngopharyngeal reflux and identifies areas of controversy and future opportunities for research. RECENT FINDINGS Despite numerous research efforts, the diagnosis and treatment of laryngopharyngeal reflux remain elusive and unproven. Acid-induced changes in laryngopharyngeal mucosa have been confirmed by histologic evidence. However, the implications of this for laryngeal symptoms and signs are unclear. Diagnosis remains controversial, confounded by lack of standardization and accepted, evidence-based norms. Whereas treatment is generally believed by clinicians to be effective in alleviating symptoms and signs attributed to laryngopharyngeal reflux, incontrovertible data confirming efficacy are scarce. Confounding the issues further, there are numerous studies that purport to show that various widely used treatments are not effective, although the scientific merit of virtually all of these studies has been challenged. SUMMARY Laryngopharyngeal reflux remains a controversial diagnosis. Treatment with proton pump inhibitors persists despite weak evidence supporting or refuting their utility, and well designed studies are needed to understand diagnosis, treatment, pathyophysiology, and long-term health consequences of laryngopharyngeal reflux and its treatment.

Abstract
Objectives: We performed an electron microscopic ultrastructural study of oropharyngeal epithelium in patients with laryngopharyngeal reflux (LPR) and sore throat to evaluate whether dilatation of intercellular spaces could be traced at this level. Methods: The study included 20 patients with LPR and sore throat and 5 control subjects. The patients were subjected to upper gastrointestinal tract endoscopy and flexible pharyngolaryngoscopy. Oropharyngeal biopsy specimens were taken from the patients and controls for ultrastructural study by transmission electron microscopy. Results: The entire group of patients with LPR showed dilatation of intercellular spaces essentially at the squamous basal and suprabasal levels in their oropharyngeal biopsy specimens, whereas none of the control subjects showed such a morphological marker. Conclusions: Dilatation of intercellular spaces as a morphological marker can be traced in patients with LPR and sore throat at the level of the oropharynx. This contributes to a better understanding of the pathophysiology of LPR. If this finding is confirmed in a large series, it will represent a cost-effective, relatively noninvasive method for diagnosis of LPR.

Abstract
Streptococcus pneumoniae, a leading cause of otitis media (OM), undergoes spontaneous intra-strain variations in colony morphology. Transparent (T) variant is more efficient in colonizing the nasopharynx while the opaque (O) variant exhibits greater virulence during systemic infections. We hypothesized that changes in middle ear (ME) gas pressure/composition during Eustachian tube (ET) dysfunction and the treatment of that dysfunction, e.g., tympanostomy tube (TT) insertion, play a role in selecting the S. pneumoniae variant that can efficiently colonize/infect the ME mucosa. Human ME epithelial cells were preconditioned for 24h under one of three conditions that simulated (1) normal ME, (2) ME with ET obstruction (ETO) and (3) ME with TT; subsequently exposed to a dose (approximately 10(7)CFU/ml) of either T or O variant of S. pneumoniae, and then incubated for 1h and 3h. Under the simulated ETO and TT conditions, T variant exhibited a higher growth rate and greater epithelial adherence and killing than did O variants. Attachment of T variant to epithelial cells was documented by scanning electron microscopy. These results suggest that the T variant is more highly adapted to various ME environments than the O variants.
