Diagnosis and management of laryngopharyngeal reflux disease

Measuring Perceived Voice Disorders and Quality of Life among Female University Teaching Faculty

BACKGROUND

Occupations that require heavy vocal use can place the person at risk of voice disorders (VDs). Heavy demands on the voice, especially for a long time or with loud back-ground noise, can lead to vocal abuse or misuse. The study aimed to measure the prevalence of perceived voice disorders among the teaching faculty at a female university, identify the risk fac-tors that affect their voice, and determine the effect of perceived voice disorders on their quality of life (QoL).

METHODS

The study sample consisted of female teaching faculty (N = 401). The ques-tionnaire included general sociodemographic data, general voice data, the vocal tract discomfort (VTD) scale, and the World Health Organization Quality of Life assessment (WHOQOL)-BREF.

RESULTS

The results demonstrated that 44.1% of the participants had perceived voice disorders, and stress, reflux, and asthma had a significant relationship with self-perceived voice disorders. Furthermore, the data showed that self-perceived voice disorders negatively impacted the overall QoL of teaching faculty.

CONCLUSIONS

Perceived voice disorders are affected by various factors, including health conditions, medications, and lifestyle choices. Although teaching characteristics and demo-graphic factors are believed to be the cause, in this study they did not significantly contribute to perceived voice disorders. Faculty members with perceived voice disorders have a poorer quality of life, highlighting the need for education on preventative vocal measures and awareness of voice care.

Analysis of clinical characteristics in proximal and distal reflux monitoring among patients with gastroesophageal reflux disease

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.

The Role of Empirical Treatment with Proton Pump Inhibitor as a Diagnostic Tool in Laryngopharyngeal Reflux

The presentations of laryngopharyngeal reflux (LPR) are diverse and include chronic hoarseness, sensation of foreign body in the throat, sore throat etc. 24 h pH monitoring considered the gold standard of investigation for LPR is costly, cumbersome and not readily available at all centers. Empirical trial of Proton pump inhibitor (PPI) as a diagnostic tool after assessment by Reflux Symptom Index (RSI) and Reflux Findings Score (RFS) is a cheaper, simple and readily available alternative. The objectives of the study were to determine clinical manifestations in patients presenting with LPR and to evaluate the role of empirical treatment with PPI as a diagnostic tool in LPR. 100 patients were divided into experimental group (RSI ≥ 13 and RFS ≥ 7) and control group (RSI < 13 and RFS < 7). Omeprazole trial was given to experimental group and assessed for RSI and RFS at 04 and 08 weeks. Statistical analysis was done within the group and between the groups. (1) The response rate to Omeprazole at 04 and 08 weeks interval (RSI<13 and/or RFS<7) was 60% and 76% respectively. (2) The response to Omeprazole given to the experimental group with RSI≥13 and RFS≥7 was significant at 04 weeks and 08 weeks duration (P<0.0001). RSI and RFS are good clinical tools to assess and diagnose patients with Laryngopharyngeal reflux. Based on the clinical diagnosis an empirical trial of a proton pump inhibitor (PPI) can be given to patients for duration of 02 months resulting in a good response.

Manifestations of ENT Caused By Gastroesophageal Reflux Disease

Introduction. The presence of gastric reflux in the pharynx and larynx causes reflux laryngopharyngitis. The incidence of laryngopharyngeal reflux has increased dramatically in recent years, but with the introduction of flexible fiber optic esophagoscopy, evidence-based research on gastroesophageal reflux disease has evolved greatly. Laryngoscopy is the main investigation to be performed to establish the diagnosis of reflux.

Material and methods. This study is both retrospective and prospective, the first being performed on a group of 175 patients, who presented in the ENT outpatient clinic, within the County Emergency Clinical Hospital “St. Andrew the Apostle” Constanta.

The aim of this paper is to evaluate and compare the manifestations of ENT caused by reflux disease but also to establish the correct therapeutic conduct.

Statins and gastroesophageal reflux disease: A meta-analysis

Background/Objectives

Gastroesophageal reflux disease (GERD) is one of the common gastrointestinal disorders worldwide. Recent epidemiologic studies have suggested that use of statins may lower the risk of GERD although the results from different studies were inconsistent. This systematic review and meta-analysis were conducted with the aim to summarize all available data.

Methods

A systematic literature review was performed using MEDLINE and EMBASE database from inception to December 2017. Cohort, case-control, and cross-sectional studies that compared the risk of GERD among statin users versus nonusers were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method.

Results

A total of 4 studies (1 case control, 1 cohort, and 2 cross-sectional studies) with 14,505 participants met the eligibility criteria and were included in the meta-analysis. The risk of GERD among statin users was numerically lower than nonusers with the pooled OR of 0.89 but the result did not achieve statistical significance (95% CI, 0.60-1.33). The statistical heterogeneity in this study was moderate (I² = 54%).

Conclusions

The current meta-analysis found that the risk of GERD was numerically lower among statin users although the pooled result did not reach statistical significance. Therefore, more studies are still needed to further clarify this potential benefit of statins.

Anorexia, Oral Health and Antioxidant Salivary System: A Clinical Study on Adult Female Subjects

The aim of this study was to compare the oral health status and salivary antioxidant system between patients diagnosed with anorexia nervosa (AN) and healthy controls. A total of 25 female AN patients and 25 matched healthy controls were enrolled. Clinical parameters and saliva samples were collected for each patient. Two questionnaires to investigate oral health and hygiene were administered. Superoxide Dismutase (SOD) activity and High Reactive Oxygen Species (hROS) were evaluated. Salivary concentration of SOD was significantly higher in subjects with AN compared with control group (1.010 ± 0.462 vs. 0.579 ± 0.296 U/mL; p = 0.0003). No significant differences between groups were identified for hROS (233.72 ± 88.27 vs. 199.49 ± 74.72; p = 0.15). Data from questionnaires indicated that, although most of the patients recognized the oral hygiene importance in maintaining a good oral health, more than half of them had poor oral hygiene. Altered biochemical composition of saliva in patients with AN could be interpreted as an effective defence mechanism against oxidative stress. Moreover, despite the discrepancy between clinical findings and perception of the oral health in AN population arose, the quality of life of these patients appears not to be significantly affected by their dental condition.

Clinical outcomes of laryngopharyngeal reflux treatment: A systematic review and meta-analysis

OBJECTIVES

To investigate the therapeutic benefit of proton pump inhibitors (PPIs) over placebo in patients with laryngopharyngeal reflux (LPR) and to analyze the epidemiological factors of heterogeneity in the literature.

METHODS

An electronic literature search was conducted to identify articles published between 1990 and 2018 about clinical trials describing the efficiency of medical treatment(s) on LPR. First, a meta-analysis of placebo randomized controlled trials (RCTs) comparing PPIs versus placebo was conducted according to diet. The heterogeneity, response to PPIs, and evolution of clinical scores were analyzed for aggregate results. Second, a systematic review of diagnosis methods, clinical outcome of treatment, and therapeutic regimens was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

RESULTS

The search identified 1,140 relevant publications, of which 72 studies met the inclusion criteria for a total of 5,781 patients. Ten RCTs were included in the meta-analysis. The combined relative risk was 1.31 in favor of PPIs and increased to 1.42 when patients did not receive diet recommendations. Randomized controlled trials were characterized by a significant heterogeneity due to discrepancies in clinical therapeutic outcomes, diagnosis methods (lack of gold standard diagnostic tools), and therapeutic scheme. The epidemiological analysis of all articles supports the existence of these discrepancies in the entire literature. In particular, many symptoms and signs commonly encountered in LPR are not assessed in the treatment effectiveness. The lack of diagnosis precision and variability of inclusion criteria particularly create bias in all reported and included articles.

CONCLUSION

This meta-analysis supports a mild superiority of PPIs over placebo and the importance of diet as additional treatment but demonstrates the heterogeneity between studies, limiting the elaboration of clear conclusions. International recommendations are proposed for the development of future trials. Laryngoscope, 129:1174-1187, 2019.

Treatment of post-intubation laryngeal granulomas: systematic review and proportional meta-analysis

INTRODUCTION

Laryngeal granulomas post intubation are benign but recurrent lesions. There is no consensus for its treatment.

OBJECTIVE

To describe the effectiveness of different treatment modalities for primary or recurrent laryngeal granulomas resulting from endotracheal intubation.

METHODS

Systematic review and proportional meta-analysis. Eligibility criteria - experimental or observational studies with at least five subjects. Outcomes studied - granuloma resolution, recurrence, and time for resolution. Databases used - Pubmed, Embase, Lilacs, and Cochrane. The Stats Direct 3.0.121 program was used.

RESULTS

Six studies were selected, with 85 patients. The treatments registered were: antireflux therapy, speech therapy, anti-inflammatory drugs, steroids, antibiotics, zinc sulfate and surgery. 85 patients from six studies had primary treatment: surgery±associations (41 patients), resolution chance 75% (95% CI: 0.3-100%, I2=90%), absolute relapse risk 25% (95% CI: 0.2-71%); medical treatment (44 patients), resolution chance 86% (95% CI: 67-97%); and absolute relapse risk 14% (95% CI: 3-33%). There was no significant difference between groups. Three studies, encompassing 19 patients, analyzed secondary treatment (failure or recurrence after primary treatment); three subjects presented new recurrence. The time needed to resolve the lesions varied from immediate, after surgery, to 23 months, for inhaled steroid.

CONCLUSION

There is no evidence of high quality that proves the efficacy of any treatment for laryngeal granulomas resulting from endotracheal intubation.

Cross-cultural Adaptation and Validation of the Greek Voice Handicap Index-10 (GVHI-10) With Additional Receiver Operating Characteristic Analysis

OBJECTIVE(S)

The use of subjective evaluation tools are proven useful and of high clinical value in the case of voice disordered population. For that type of evaluation, self-assessment questionnaires about the severity of the voice like Voice Handicap Index-30 (VHI-30) have been developed. The VHI-30 is the most studied tool which includes psychometrically robustness while guiding physician's therapeutic decision making. Additionally, a valid abbreviated version of VHI-30 was developed for the first time in the Greek Language which is named as Greek Voice Handicap Index-10 (GVHI-10). Consequently, the aim of our study was to validate the proposed version of the VHI-10.

METHODS

Ninety nondysphonic individuals and 90 dysphonic patients were classified by Otolaryngologists and Speech Language Pathologists. The study's subjects were evaluated with endoscopy and stroboscopy. Also, they were administrated the GVHI-30 and the translated version of the Voice Evaluation Template (VEF). The GVHI-10 was extracted by the Greek version of VHI-30.

RESULTS

The group with voice disorders exhibited higher statistical significance in all GVHI-10 scores compared to those of the control group. The GVHI-10 showed a high internal consistency (Cronbach's a = 0.915 and split-half reliability coefficient equal to 0.86), good sensitivity compared to Greek VHI-30 (r = 0.764, P = 0.000) and intraclass correlation. A total cut-off point equal to 6.50 (AUC: 0.964; P < 0.001) was also calculated.

CONCLUSIONS

The proposed version of GVHI-10 distinguished the perceived levels of voice between dysphonic and nondysphonic groups and between different voice disordered populations. The GVHI-10 is shown to be clinically valid and sensitive exhibiting high reliability.

The Diagnostic Usefullness of the Salivary Pepsin Test in Symptomatic Laryngopharyngeal Reflux

OBJECTIVE

Laryngopharyngeal Reflux (LPR) is a disease characterized by the presence of symptoms, signs and tissue alterations in the aero-digestive upper tract as a consequence of the gastric contents retrograde movement. In most cases diagnosis is clinical and it is established by the presence of symptoms and endoscopic laryngeal signs. The aim of the study was to determine the sensitivity, specificity, positive and negative Likelihood Ratio (LR) of the salivary pepsin assay (PEP-test, RD Biomed, Hull, UK) as diagnostic tool of LPR.

STUDY DESIGN

Diagnostic Accuracy Study.

METHOD

221 subjects aged between 26 and 68 years were recruited. All subjects completed the Reflux Symptom Index scale. PEP-test was carried out on fasting subjects, and a second test was performed one hour after the main meal, only on those subjects with a fasting negative result.

RESULTS

Fasting PEP-test showed a 98% specificity, 40% sensitivity, positive LR of 16.4 and negative LR of 0.61. The use of both PEP-test showed a 95% specificity, 48% sensitivity, positive LR of 9.61 and negative LR of 0.55.

CONCLUSIONS

The PEP-test is a simple, inexpensive, non-invasive and easily reproducible test that should be considered as an alternative diagnosis tool for LPR diagnosis. When there is a clinical suspicion of LPR disease, a positive result on the test could be considered diagnostic, but on subjects with negative results it should be complemented with more complex tests such as the 24-hour dual-channel pH-metry.

Relação entre os sintomas vocais, intensidade do desvio vocal e diagnóstico laríngeo em pacientes com distúrbios da voz

RESUMO Objetivo investigar se existe associação entre a frequência de ocorrência dos sintomas vocais, a intensidade do desvio vocal e o diagnóstico laríngeo em pacientes com diferentes distúrbios da voz. Métodos Participaram do estudo 330 pacientes com queixa vocal, distribuídos em cinco grupos de acordo com o diagnóstico laringológico: G1-sem lesão laríngea, G2-lesões benignas das pregas vocais, G3-distúrbio neurológico da voz, G4-fenda glótica sem causa orgânica ou neurológica e G5-distúrbio de voz secundário a refluxo gastroesofágico. Foram alocados em cinco grupos, de acordo com o diagnóstico laríngeo. Todos os participantes responderam à Escala de Sintomas Vocais (ESV) e gravaram a vogal /ɛ/ sustentada, que foi analisada quanto à intensidade do desvio vocal por meio de uma escala analógico-visual. Resultados Houve diferença nos escores total, de limitação e físico da ESV entre diferentes grupos diagnósticos. Pacientes com lesão na porção membranosa das pregas vocais apresentaram maior número de sintomas vocais em relação aos outros grupos diagnósticos. Observou-se correlação positiva entre a intensidade do desvio vocal e os escores total, de limitação e emocional da ESV. Pacientes com desvio vocal moderado e intenso apresentaram maior número de sintomas vocais que pacientes com vozes saudáveis ou com desvio leve. Conclusão Existe associação entre o diagnóstico laríngeo, a intensidade do desvio vocal e a frequência de ocorrência dos sintomas vocais. Pacientes com lesão benigna nas pregas vocais e com desvio vocal mais intenso apresentam maior frequência de sintomas vocais.

Pathophysiology and treatment of patients with globus sensation--from the viewpoint of esophageal motility dysfunction

"Globus sensation" is often described as the sensation of a lump in the throat associated with dry swallowing or the need for dry swallowing, which disappears completely during eating or drinking and for which no organic cause can be established. Due to the uncertain etiology of "globus sensation", it remains difficult to establish standard treatment strategies for affected patients. Lately most attention has been focused on gastroesophageal reflux disease and several reports have indicated that there is a close relationship between esophageal acid reflux and globus sensation. Nowadays, empirical therapy with a high dose of a proton pump inhibitor (PPI) is considered to be indicated for patients with globus sensation, after excluding organic diseases such as pharyngeal cancer, Zenker's diverticulum, or thyroid enlargement. If patients are nonresponsive to PPI therapy, evaluation of esophageal motility should be done. In our recent study, 47.9% had abnormal esophageal motility, with the most common esophageal motility abnormality being an ineffective esophageal motility in PPI-resistant patients with globus sensation. This suggests that prokinetics alone or adding prokinetics to PPI should be the treatment to be considered, although few studies have investigated the efficacy of prokinetics in the treatment of patients with globus sensation. If patients without any esophageal motility dysfunctions are nonresponsive to PPI therapy, either cognitive-behavioral therapy, anti-depressants, or gabapentin could be helpful, although further well-designed, randomized controlled large-scale studies will be necessary to determine the effectiveness of each treatment strategy on patients with globus sensation.

How uncomplicated total thyroidectomy could aggravate the laryngopharyngeal reflux disease?

Swallowing, voice disorders, throat discomfort and subjective neck discomfort are usually reported by patients with a known thyroid nodule and are correlated to nodular thyroid disease itself. Moreover, in endemic goitrous areas, total thyroidectomy (TT) is the most frequently performed surgical procedure. We are used to relate swallowing, voice and throat discomfort to the mechanical effects of nodular goiter or to thyroidectomy itself, but in both these cases the relationship between symptoms and the thyroid mass or its removal is not always clear or easily demonstrated. How can we explain the persistence of local neck symptoms after TT? And how can TT worsen the dysphagic or dysphonic disorders attributed to the goiter's effect over the surrounding structures? During these years, many articles have analyzed the relationship between the thyroid disease and the laryngopharyngeal reflux, finding more and more evidences of their consensuality, leading to important new management considerations and notable medico-legal implications; if the reason of local neck symptoms is not the thyroid disease, we have to study and specially cure the reflux disease, with specific test and drugs. Therefore, the aim of our study, relying on the published literature, was to investigate how, in demonstrated presence of reflux laryngopharyngitis in patients with nodular goiter and local neck symptoms before and after uncomplicated TT, the surgery could influence our anti-reflux mechanism analyzing the anatomical connection as well as the functional coordination; can we play a part in the post-operative persistence of swallowing and voice alterations and throat discomfort?

LPR: how different diagnostic tools shape the outcomes of treatment

OBJECTIVE

To seek a deeper and more comprehensive understanding of two major diagnostic methods for laryngopharyngeal reflux by exploring whether and how differences exist before and after treatment between patients diagnosed by either Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) or 24-hour pH monitoring.

MATERIALS AND METHODS

Two groups of patients who confirmed laryngopharyngeal reflux disease (LPRD) by either a combination of RSI and RFS (Questionnaire group, 35 patients) or 24-hour multichannel intraluminal impedance (MII) pH monitoring (pH Group, 23 patients) were recruited. All patients were prescribed esomeprazole 20 mg twice a day for 1 month. RSI, RFS, and acoustic parameters before and after treatment were compared between the two groups. Intrinsic correlations involving multiple parameters were investigated as well.

RESULTS

Except for excess throat mucus (P = 0.019) and subglottic edema (P = 0.042), most RSI and RFS items before treatment were not significantly different between the Questionnaire and pH Groups, and nearly all such items in both groups exhibited distinct remission after therapy (P < 0.05). Absolute value of remission in RSI after treatment was more prominent in pH Group than in the Questionnaire group (P = 0.007). Jitter (P = 0.252), shimmer (P = 0.815), and harmonics-to-noise ratio (P = 0.117) descended to normal value after treatment. Moderate to high levels of correlation were found between the patient's original status and the absolute value of remission in most items of RSI and RFS as well as voice parameters.

CONCLUSION

The 24-hour MII pH monitoring and a combination of RSI and RFS are quite competitive with each other in selecting LPRD patients. Although treatment worked out on nearly all the symptoms, laryngeal images and voice parameters, 24-hour MII pH seems to be more promising in a greater symptom relief. The extent of relief that can take place in most of the measurements is considerably determined by their initial status.

Influence of obesity on the correlation between laryngopharyngeal reflux and obstructive sleep apnea✩✩Please cite this article as: Rodrigues MM, Dibbern RS, Santos VJ, Passeri LA. Influence of obesity on the correlation between laryngopharyngeal reflux and obstructive sleep apnea. Braz J Otorhinolaryngol. 2014;80:5-10

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.

Diagnosis and management of laryngo-pharyngeal reflux

The aim of the present paper was to analyze laryngo-pharyngeal reflux (LPR) manifestations in ENT patients, and present a diagnostic and treatment algorithm for appropriate management. Retrospective chart review of 150 patients, who had initially presented with symptoms suggestive of LPR. Treatment included the administration of omeprazole 20 mg twice daily for at least 4 weeks. Unresponsive patients were also given metoclopramide 10 mg twice daily for four additional weeks, and the dose of omeprazole was increased to 40 mg twice daily, if they did not achieve complete symptom resolution. Only patients who became completely asymptomatic after LPR treatment were included in the study. As many as 18 % of patients attending an ENT outpatient department benefited from anti-reflux treatment. A need to clear the throat represented the most common symptom, whereas interarytenoid oedema/congestion was the most common finding on flexible naso-endoscopy (62.67 and 72.7 % of patients, respectively). The vast majority of patients responded after 4 weeks of treatment with omeprazole, however, as many as 32 % of LPR patients achieved complete symptom control after the initial 4 week trial period. LPR seems to be more common than previously reported in the literature. Appropriate management of LPR can prevent the symptomatic use of various medical treatments for related manifestations, and even surgical interventions, thus decreasing the overall patient morbidity.

Globus pharyngeus: A review of its etiology, diagnosis and treatment

Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat. It is a commonly encountered clinical condition that is usually long-lasting, difficult to treat, and has a tendency to recur. Furthermore, due to the uncertain etiology of globus, it remains difficult to establish standard investigation and treatment strategies for affected patients. As a first step for managing globus, careful history taking and nasolaryngoscopy are essential. Given the benign nature of the condition and the recent notion that gastroesophageal reflux disease is a major cause of globus, empirical therapy with a high dose of proton pump inhibitors is reasonable for patients with typical globus. If patients are nonresponsive to this therapy, definitive assessments such as endoscopy, multichannel intraluminal impedance/pH monitoring, and manometry should be considered. Speech and language therapy, anti-depressants, and cognitive-behavioral therapy can be helpful in patients whose symptoms persist despite negative investigations.

Eating disorders and oral health: a matched case-control study

The aim was to compare the oral health status of patients with eating disorders (EDs), with sex- and age-matched controls, with a view to identify self-reported and clinical parameters that might alert the dental healthcare professional to the possibility of EDs. All patients who entered outpatient treatment in an ED clinic during a 12-month period were invited to participate. Of 65 ED patients who started psychiatric/medical treatment, 54 agreed to participate. Eating disorder patients and controls answered a questionnaire and underwent dental clinical examinations. Multivariate analysis identified significantly higher ORs for ED patients to present dental problems (OR = 4.1), burning tongue (OR = 14.2), dry/cracked lips (OR = 9.6), dental erosion (OR = 8.5), and less gingival bleeding (OR = 1.1) compared with healthy controls. Sensitivity and specificity for the correct classification of ED patients and controls using the five variables was 83% and 79%, respectively. The ED patients with vomiting/binge eating behaviors reported worse perceived oral health (OR = 6.0) and had more dental erosion (OR = 5.5) than those without such behavior. In ED patients with longer duration of the disease, dental erosion was significantly more common. In conclusion, oral health problems frequently affect ED patients, and this needs to be considered in patient assessment and treatment decisions.

The Challenge of Protocols for Reflux Disease

Objectives. Gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) are very common and controversial diseases. The authors have previously reviewed clinical practice guidelines (CPGs) on reflux disease, and these major consensus statements differ on what constitutes ideal management. The aim is to critically review existing protocols for reflux based on CPG recommendations and to present a refined protocol that may be further used to develop a critical pathway for reflux in ambulatory medical practice.

Study Design. Literature review with discussion.

Methods. A PubMed search was used to identify current clinical protocols or algorithms for reflux disease, and the principal elements of each were compared.

Results. Of the 828 articles identified in the search, 11 met the search criteria. Together with 4 articles previously identified, 15 were analyzed. All protocols discuss the important role of empiric therapy, although with differences in use. Only 5 protocols (33%) were based on systematic review such as CPGs. Eight protocols (53%) used alarm symptoms to prompt a workup. For these patients, upper endoscopy was by far the most common diagnostic method. The use of other modalities varies significantly between protocols. The authors propose a standard protocol based on patient risk factors that employs CPG recommendations and may be used for critical pathway outcomes measures.

Conclusion. There are major differences between existing protocols for reflux disease in the literature, reflecting many clinical controversies. Outcomes of different protocols have not been extensively studied. The authors propose a new protocol that is a synthesis of those reviewed and based on risk stratification.

Controversies in the evaluation and management of chronic cough

Chronic cough that cannot be explained after basic evaluation is a common reason for patients to be referred to respiratory outpatient clinics. Asthma, gastroesophageal reflux, and upper airway disorders frequently coexist with chronic cough. There is some controversy as to whether these conditions are causes or aggravants of cough. Heightened cough reflex sensitivity is an important feature in most patients. There is good evidence that it is reversible when associated with upper respiratory tract infection, angiotensin-converting enzyme inhibitor medications, and chronic cough associated with eosinophilic airway inflammation. In many patients, heightened cough reflex sensitivity is persistent and their cough is unexplained. There are few therapeutic options for patients with unexplained chronic cough. There is a pressing need to understand the genetic, molecular, and physiological basis of unexplained chronic cough and to develop novel antitussive drugs that down-regulate cough reflex sensitivity.

Globus jugularis and dysphagia in patients with hiatus hernia

The aim of the article was to study if there is any relationship between globus sensation in the jugular fossa (GJ), intermittent esophageal dysphagia (IED), and the presence of a hiatus hernia, and if GJ can be relieved after hiatus hernia repair. 167 patients with a hiatus hernia (Group A) and 61 other patients with hiatus hernia and gastroesophageal reflux disease who were surgically treated with Nissen fundoplication (Group B), filled in a symptom questionnaire on GJ and IED. GJ was found in 66% and IED in 68% of patients in group A. In group B, 49% had GJ and 64% IED before surgery. At surgical follow-up 16% (P < 0.005) and 43% (P < 0.05) had GJ and IED, respectively. The combination of GJ and IED was found in 28% of IED patients before operation and in 31% at surgical follow-up. The high frequency of GJ in patients with hiatus hernia and the significant relief of GJ after hiatus hernia repair imply that GJ most likely is a referred sensation from the esophagus. IED and GJ are two parallel phenomena in patients with hiatus hernia, but do not seem to have any causal relationship.

Revision adenoidectomy--a retrospective study

BACKGROUND

Adenoid "re-growth" is a poorly understood phenomenon. While parents often express concerns regarding the potential for adenoid "re-growth", little information exists in the literature about its incidence and causation.

PURPOSE

To establish the incidence and possible contributing factors leading to adenoid re-growth in children.

DESIGN

Retrospective case series review.

SETTING

Tertiary care children's hospital.

METHODS

The charts of 106 patients who underwent revision adenoidectomy between 1995 and 2006 were reviewed. Thirty-four patients were excluded because the primary adenoidectomy was performed elsewhere or initially only a partial adenoidectomy was performed. In the remaining 72 patients, demographic data, clinical presentation, associated medical conditions and findings at surgery were studied.

RESULTS

During the 11-year study period. 13,005 adenoidectomies or adenotonsillectomies were performed; 72/13,005 (0.55%) underwent revision adenoidectomy. The mean (+/-S.D.) age at presentation for primary adenoidectomy was 3.68+/-2.9 and 7.69+/-4.04 years for secondary ("revision") adenoidectomy with an average time interval of 4.3 years between surgeries. Age at initial adenoidectomy was not a significant factor in predicting revision adenoid surgery. 29/72 (40%) underwent a reflux work up including scintiscan with gastric emptying, 24h pH probe, or laryngoscopy. 28/29 (96%) were diagnosed with reflux. At least 15/72 (21%) were reported to have symptoms consistent with adenoid re-growth which were found to be caused by tubal tonsil hyperplasia.

CONCLUSIONS

Revision adenoidectomy rarely needs to be performed. Tubal tonsillar hyperplasia, as opposed to re-growth of residual adenoid tissue previously removed, accounts for some cases. Extraesophageal reflux is a possible cause in some and requires further study.

[Laryngopharyngeal morbidity following general anaesthesia. Anaesthesiological and laryngological aspects]

Laryngeal and pharyngeal complaints are among the subjective problems most frequently reported by patients after general anaesthesia involving endotracheal intubation, others being pain, nausea and vomiting. Hoarseness, sore throat, and vocal cord injuries restrict patients' social lives, and in some cases also their working lives. The most frequent types of laryngeal injury are swollen mucosa and haematoma of the vocal cords. Vocal cord paralysis occurs much less frequently. Knowledge of the pathophysiological aspects and other relevant factors associated with laryngopharyngeal morbidity are essential cornerstones of quality assurance in perioperative respiratory tract management. In this review specific sections are devoted to the implications of anaesthesia involving endotracheal intubation and laryngeal masks for laryngopharyngeal morbidity, and also particular aspects of thyroid gland surgery, cardiothoracic and bariatric surgery and obstetric and paediatric anaesthesia, and medicolegal aspects.

Non-linear associations between laryngo-pharyngeal symptoms of gastro-oesophageal reflux disease: clues from artificial intelligence analysis

The relationship between the different symptoms of gastro-oesophageal reflux disease remain markedly obscure due to the high underlying non-linearity and the lack of studies focusing on the problem. Aim of this study was to evaluate the hidden relationships between the triad of symptoms related to gastro-oesophageal reflux disease using advanced mathematical techniques, borrowed from the artificial intelligence field, in a cohort of patients with oesophagitis. A total of 388 patients (from 60 centres) with endoscopic evidence of oesophagitis were recruited. The severity of oesophagitis was scored by means of the Savary-Miller classification. PST algorithm was employed. This study shows that laryngo-pharyngeal symptoms related to gastro-oesophageal reflux disease are correlated even if in a non-linear way.
