Objective: To investigate the characteristics of salivary microbiota in patients with laryngopharyngeal reflux (LPR). Methods: A case-control study was applied to enroll 60 patients and healthy subjects who were outpatients of the Department of Otorhinolaryngology Head and Neck Surgery of the Eighth Medical Center of the PLA General Hospital from December 2020 to March 2021, including 35 males and 25 females, aged from 21 to 80 (33.75±11.10) years. Thirty patients with suspected laryngopharyngeal reflux were selected as study group and thirty healthy volunteers without pharyngeal symptoms were selected as control group. Their salivary samples were collected, and the salivary microbiota was detected and analyzed by 16S rDNA sequencing. SPSS 18.0 software was used for statistical analysis. Results: There was no significant difference in the diversity of salivary microbiota between the two groups. At the phylum classification level, the relative abundance of Bacteroidetes in the study group was higher than that in the control group[37.86(31.15, 41.54)% vs 30.24(25.51, 34.18)%,Z=-3.46,P<0.01]. And the relative abundance of Proteobacteria in the study group was lower than that in the control group [15.76(11.81, 20.17)% vs 20.63(13.98, 28.82)%, Z=-1.98,P<0.05]. At the genus level, the relative abundance of Prevotella, Lactobacillus, Parascardovia and Sphingobium in the study group was higher than that in the control group(Z values were-2.92, -2.69, -2.05, -2.31, respectively, P<0.05).And the relative abundance of Streptococcus, Cardiobacterium, Klebsiella and Uruburuella of study group was lower than that of control group(Z values were -2.43, -2.32, -2.17, -2.32, respectively, P<0.05). LEfSe difference analysis showed that there were 39 bacteria with significant differences between the two groups, including Bacteroidetes, Prevotellaceae and Prevotella, which were enriched in the study group, and Streptococcaceae, Streptococcus and other taxa, which were enriched in the control group(P<0.05). Conclusion: The changes of the microflora in the saliva between LPR patients and healthy people suggest that the dysbacteriosis might exist in LPR patients, which may play an important role in the pathogenesis and development of LPR.

Objective: To investigate the characteristics of the time-point distribution of the occurrence of laryngopharyngeal reflux (LPR) by 24-hour multichannel intraluminal impedance-pH monitoring (24 h MII-pH) and to provide guidance for the development of individualized anti-reflux strategies for LPR patients. Methods: We conducted a retrospective analysis of 24 h MII-pH data from 408 patients [339 males and 69 females, aged 23-84 (55.08±11.08) years] attending the Department of Otorhinolaryngology Head and Neck Surgery at the Sixth Medical Center of the PLA General Hospital from January 2013 to March 2020. The number of gas acid/weak-acid reflux, mixed gas-liquid acid/weak-acid reflux, liquid acid/weak-acid reflux and alkaline reflux events at different time points were recorded and statistically analyzed through SPSS 26.0 software. Results: A total of 408 patients were included. Based on the 24 h MII-pH, the total positive rate of LPR was 77.45% (316/408). The type of positive gaseous weak-acid reflux was significantly higher than the remaining types of LPR (χ2=297.12,P<0.001). Except the gaseous weak-acid reflux, the occurrence of the remaining types of LPR showed a tendency to increase after meals, especially after dinner. Liquid acid reflux events occurred mainly between after dinner and the following morning, and 47.11% (57/121) of them occurred within 3 h after dinner. There was a significant positive association between Reflux Symptom Index scores and gaseous weak-acid reflux(r=0.127,P<0.01), liquid acid reflux(r=0.205,P<0.01) and liquid weak-acid reflux(r=0.103,P<0.05)events. Conclusions: With the exception of gaseous weak-acid reflux events, the occurrence of the remaining types of LPR events has a tendency to increase after meals, especially after dinner. Gaseous weak-acid reflux events accounts for the largest proportion of all types of LPR events, but the pathogenic mechanisms of gaseous weak-acid reflux are needed to further investigate.

At present, objective methods for diagnosing laryngopharyngeal reflux disease(LPRD) are not minimally invasive, effective, and economical. Diagnostic scales are widely used worldwide due to the advantages of inexpensive, noninvasive, and easy to operate. The reflux symptom index(RSI) and the reflux finding score(RFS) are preferred to use in clinical diagnosis. However, many controversies have appeared in the application of RSI and RFS in recent years, causing many troubles to clinical diagnosis. Therefore, this review briefly discusses the problems of RSI and RFS in clinical applications to provide reference for diagnosing LPRD accurately.

Resumo Introdução: Muitos problemas relacionados à laringe têm sido atribuídos ao refluxo laringofaríngeo, inclusive disfonia, pigarro frequente, tosse crônica e sensação de "globus" faríngeo. No entanto, ainda há controvérsias quanto ao diagnóstico e à apresentação clínica dessa condição clínica. Objetivo: Descrever as características do refluxo laringofaríngeo de diferentes posições, em pacientes diagnosticados por meio de pHmetria orofaríngea. Método: Foi feita uma revisão retrospectiva de prontuários de 161 pacientes com refluxo laringofaríngeo diagnosticado por pHmetria orofaríngea de 24 horas. Os indivíduos do estudo foram categorizados em grupos com refluxo laringofaríngeo na posição ortostática e refluxo laringofaríngeo na posição supina com base nos resultados do pH. Os dois grupos foram comparados quanto à apresentação clínica e às características do pH. Resultados: Foram encontradas taxas significativamente mais altas de refluxo laringofaríngeo na posição ortostática em comparação à posição supina (p < 0,0001). Os resultados do índice de sintomas de refluxo foram significativamente maiores no grupo com refluxo laringofaríngeo na posição ortostática em comparação com o grupo com refluxo laringofaríngeo na posição supina. O uso do escore de Ryan composto (composite Ryan score) para a pHmetria orofaríngea de 24 horas foi significantemente maior no grupo com refluxo laringofaríngeo ortostático em relação ao grupo supino (p < 0,0001). Nenhuma diferença significante foi encontrada entre os grupos refluxo laringofaríngeo na posição ortostática e posição supina em relação à frequência da apresentação clínica ou classificações do índice de desvantagem vocal. Conclusão: O refluxo laringofaríngeo foi mais prevalente na posição ortostática entre os grupos de estudo. As características relacionadas ao refluxo, inclusive parâmetros de pH, foram mais evidentes no refluxo laringofaríngeo na posição ortostática.

RESUMO Objetivo: Verificar a associação entre Refluxo laringofaríngeo (RLF) com idade, sexo, desvio vocal e queixas de voz. Método: Participaram do estudo pacientes entre 18 e 70 anos, encaminhados ao serviço de otorrinolaringologia por queixas de voz ou refluxo, de ambos os sexos. Os achados endolaríngeos foram classificados utilizando a escala Reflux Finding Score (RFS). A presença ou não de queixas vocais e de refluxo foi verificada e correlacionada com a classificação RFS. Na mesma data, os pacientes foram submetidos à gravação de voz de vogal sustentada e fala encadeada. A avaliação perceptivo-auditiva foi realizada por uma fonoaudióloga, classificando o grau geral do desvio vocal com base na escala GRBASI. Resultados: Foram avaliados 97 pacientes, com média de idade de 42,6 anos, sendo 62,3% do sexo feminino e média dos escores da escala RFS igual a 6,26 pontos. Do total de pacientes, 48 indivíduos apresentavam queixas vocais, sendo 34 mulheres com idade média de 44,9 anos e escore RFS médio de 6,94 pontos. Os outros 49 indivíduos não apresentavam queixas vocais, e desses 27 eram mulheres, com idade média de 41,2 anos e média de escore RFS igual a 5,5 pontos. As variáveis "queixa de refluxo", "queixa vocal" e idade foram as que mais se correlacionaram com os escores da escala RFS. Conclusão: Há relação entre queixas de refluxo, achados laríngeos e queixa vocal.

ABSTRACT Purpose: To verify the association between laryngopharyngeal reflux (LPR) with age, gender, vocal deviation and voice complaints. Methods: The study included patients between 18 and 70 years old, referred to the Otorhinolaryngology service for complaints of voice or reflux, of both sexes. Endolaryngeal findings were classified using the Reflux Finding Score (RFS) scale. The presence or absence of vocal and reflux complaints was verified and correlated with the RFS classification. On the same date, they were submitted to sustained vowel voice recording and chained speech. The auditory-perceptual assessment was performed by a speech therapist, classifying the general degree of vocal deviation based on the GRBASI scale. Results: Ninety-seven patients were evaluated, with a mean age of 42. 6 years, 62. 3% female, and mean RFS scores of 6. 26 points. Among the patients, 48 subjects had vocal complaints, 34 women with a mean age of 44. 9 years and an average RFS score of 6. 94 points. The other 49 individuals had no vocal complaints, and of these 27 were women, with a mean age of 41. 2 years and a mean RFS score of 5. 5 points. The variables "reflux complaint", "vocal complaint" and age were the ones that most correlated with the RFS scale scores. Conclusion: There is a relationship among reflux complaints, laryngeal findings and vocal complaint.

Abstract Introduction Obstructive sleep apnea syndrome and laryngopharyngeal reflux are diseases with a high prevalence in the overall population; however, it remains unclear whether they are diseases with the same risk factors present in the same populations or if there is any association between them. Objectives To evaluate and determine the prevalence of laryngopharyngeal reflux in patients with moderate and severe obstructive apnea syndrome and also to determine its predictive factors. Methods Historical cohort, cross-sectional study of patients aged 18-70 years, referred to a tertiary service Otorhinolaryngology outpatient clinic with a polysomnographic diagnosis of moderate or severe obstructive sleep apnea syndrome. The reflux symptom index questionnaire and the reflux finding score at indirect videolaryngoscopy were applied to the assessed population, considering the inclusion and exclusion criteria. Results Fifty-six patients were evaluated, of which 64.3% had a positive laryngopharyngeal reflux (positive reflux symptom index and/or positive endolaryngeal reflux finding score). Body mass index was a predictor of reflux presence in this group of patients with moderate to severe obstructive sleep apnea syndrome. In patients with positive score for endoscopic findings and reflux symptom index (12.3%), there was a trend toward significance for a higher mean apnea-hypopnea index and a higher percentage of sleep time with oxyhemoglobin saturation below 90% (p = 0.05). Conclusion The prevalence of laryngopharyngeal reflux was higher in this group of patients with moderate to severe obstructive sleep apnea syndrome, and the body mass index was a predictor of laryngopharyngeal reflux in these patients. There was a trend toward greater oxyhemoglobin desaturation in patients with a positive score for reflux symptoms index (RSI) and reflux finding score (RFS).

Resumo Introdução A síndrome da apneia obstrutiva do sono e o refluxo laringofaríngeo são doenças com alta prevalência na população em geral. No entanto, ainda não está claro se são doenças com os mesmos fatores de risco presentes nas mesmas populações ou se há alguma relação entre elas. Objetivo Avaliar e determinar a prevalência de refluxo laringofaríngeo em pacientes com síndrome da apneia obstrutiva moderada e acentuada, bem como determinar os fatores preditivos de refluxo nesses pacientes. Método Estudo de coorte histórica com corte transversal de pacientes entre 18 e 70 anos, encaminhados a um ambulatório de Otorrinolaringologia em serviço terciário, com diagnóstico polissonográfico de síndrome da apneia obstrutiva do sono moderada ou acentuada. Foram aplicados o questionário Reflux Sympton Index e o escore de achados endolaríngeos por meio de videolaringoscopia indireta na população estudada, respeitando os critérios de inclusão e exclusão. Resultados Foram avaliados 56 pacientes, dos quais 64,3% apresentaram refluxo laringofaríngeo (Reflux Sympton Index positivo e/ou Reflux Finding Score positivo). O índice de massa corpórea foi fator preditor da presença de refluxo laringofaríngeo nesse grupo de pacientes com síndrome da apneia obstrutiva do sono moderada e acentuada. Nos pacientes cujos Reflux Sympton Index e o escore de achados endolaríngeos foram positivos (12,3%), houve uma tendência à significância para maior índice de apneia e hipopneia e maior porcentagem do tempo de sono com saturação de oxi-hemoglobina abaixo de 90% (p = 0,05). Conclusão A prevalência de refluxo laringofaríngeo foi alta nesse grupo de pacientes com síndrome da apneia obstrutiva do sono moderada e acentuada e o índice de massa corpórea foi fator preditor de refluxo nesses pacientes. Houve uma tendência a maior dessaturacão de oxi-hemoglobina em pacientes com "índice de sintomas de refluxo" e escore de achados endolaríngeos positivos.

Introducción: el reflujo laringofaríngeo (RLF) es una manifestación extradigestiva del Reflujo Gastroesofágico (RGE). Actualmente, el algoritmo diagnóstico usado en la mayoría de los Servicios de Otorrinolaringologìa (ORL) consiste en identificar los síntomas sugestivos de reflujo laringofaríngeo y realizar una fibronasolaringoscopia flexible para determinar si existen cambios estructurales identificables en la laringe o en los tejidos vecinos. Se ha desarrollado una escala subjetiva para cuantificar la severidad de los cambios inflamatorios de la laringe, identificando los hallazgos laringoscópicos asociados con reflujo laringofaríngeo. Los mismos son clasificados por el índice de hallazgos de reflujo “Reflux Finding Score” (RFS), desarrollado por Belafky y cols. El puntaje máximo es de 26 y un puntaje de 7 o mayor a 7 es considerado altamente sospechoso de RLF. Objetivos: Determinar el índice Kappa de Resultados Interobservador usando el RFS en pacientes con RLF en el Servicio de Otorrinolaringología del Sanatorio Allende. Determinar las características de los pacientes con diagnóstico de RLF según: Sexo, edad, síntomas presentes y tratamiento indicado en pacientes que consultaron ambulatoriamente en el Servicio de ORL del Sanatorio Allende sucursal Nueva Córdoba. Material y método: Se determinó el índice Kappa de Resultados entre observadores usando el RFS en paciente con RLF entre 2 médicos del staff de Servicio de ORL del Sanatorio Allende, se analizó frecuencia de sexo, edad, síntomas, conducta médica. Conclusión: El índice Kappa del RFS para cada uno de los 8 ìtems del RFS es leve, medido como < 0,2.

Introduction: the Laryngopharyngeal Reflux (LPR) is recognized as an extra-digestive manifestation of gastroesophageal reflux (GERD). At present, the diagnostic algorithm used in most of the otorhinolaryngology (ORL) services involves identifying suggestive symptoms of laryngopharyngeal reflux and carrying out a flexible fibronasolaryngoscopy to determine if there are identifiable structural changes in the larynx or neighboring tissues. A subjective scale has been developed to quantify the severity of inflammatory changes in the larynx by identifying endoscopic findings related to laryngopharyngeal reflux. These subjective findings for patients with LPR are classified using the “Reflux Finding Score” (RFS) developed by Belafsky et al.The maximum score is 26 and a score of 7 or greater is considered to indicate that LPR is highly likely. Objetive: To determine the Kappa Coefficient of the interobserver agreement using the RFS in patients with LPR in the Otorhinolaryngology Service of the Allende Hospital. To determine the characteristics of patients with LPR diagnosis according to: Gender, age, manifested symptoms and treatment indicated in patients that were treated as an outpatient in the ORL Service of the Allende Hospital, Nueva Córdoba’s branch. Material and method: The Kappa Coefficient was determined by the interobserver agreement using the RFS in patients with LPR between two Staff doctors of the ORL Service of the Allende Hospital; it was investigated the sex frequency, age, symptoms and medical behavior. Conclusions: The Kappa Coefficient of LPR for each of the eight items of LPR is poor, valued as < 0.2.

Introdução: o refluxo laringofaríngeo (RFL) é uma manifestação extra-digestiva do refluxo gastroesofágico (RGE). Atualmente o algoritmo diagnóstico usado pela maioria dos Serviços de Otorrinolaringología (ORL) consistem em identificar os sintomas sugestivos do RFL e realizar uma fibronasolaringoscopia flexível para determinar se existem mudanças estruturais identificáveis na laringe ou nos tecidos vizinhos. Existe uma escala subjetiva para quantificar a severidade das alterações inflamatórias na laringe, identificando os achados laringoscópicos que têm relação com o RFL. Eles são classificados pelo índice de achados de refluxo “Reflux Finding Score” (RFS), desenvolvido por Belafky e cols. A pontuação maxima é de 26 e uma pontuação de 7 ou maior é considerado quase sugestivo de RFL. Objetivos: Determinar o índice Kappa dos resultados interobservador usando o RFS em pacientes com RFL no Serviço de Otorrinolaringologia do Sanatorio Allende. Determinar as características dos pacientes com diagnóstico de RFL Segundo: Sexo, idade, sintomas presentes e tratamento indicado em pacientes que fizeram consultas externas no Serviço de ORL do Sanatorio Allende em Nueva Córdoba. Material e método: Determinou-se o índice Kappa dos resultados entre observadores usando o RFS em pacientes com RFL entre 2 médicos do staff do Serviço de ORL do Sanatorio Allende. Analizou-se a frequência entre o sexo, a idade, os sintomas, as doenças associadas e a terapeútica médica. Conclusões: O índice Kappa do RFS para cada item do RFS é insuficiente, medida como < 0,2.

PURPOSE: We tried to evaluate the difference in the expression of carbonic anhydrase (CA) III and heat shock protein (Hsp) 70 between laryngopharyngeal reflux disease (LPRD) and non-LPRD patients. MATERIALS AND METHODS: The study involved 28 patients who underwent laryngeal microsurgery due to benign laryngeal disease from March to August 2008. Reflux symptom index (RSI) and reflux finding score (RFS) were measured for each person, and they were assigned either to the LPRD group (n=10) or non-LPRD group (n=18). Tissue samples were obtained from the mucosa of posterior commissure, and immunohistochemistry (IHC) staining of CAIII and Hsp70 was performed. The IHC scores were measured and compared with clinical features including RSI and RFS. RESULTS: Total 10 patients were assigned as LPRD group, and 18 patients were as control group. The mean IHC score of CAIII and Hsp70 was 1.70+/-1.06 and 1.90+/-0.88, respectively, in LPRD patients, whereas the mean IHC score of CAIII and Hsp70 was 0.78+/-0.73 and 0.94+/-0.87, respectively, in non-LPRD patients. The difference between two groups was statistically significant (p<0.05). CONCLUSION: CAIII and Hsp70 expressions were higher in LPRD patients that in non-LPRD patients, suggesting the possibility as one of biomomarker in LPRD diagnosis.

El reflujo faringo laríngeo (RFL), es una causa común de morbilidad del tracto aerodigestivo superior. A pesar de su alta prevalencia, aún existe controversia respecto de la precisión diagnóstica de esta enfermedad, así como de su fisiopatología y manejo. Los test diagnósticos actuales aún presentan limitaciones significativas, de ahí que surja el interés por encontrar métodos rápidos y eficientes que mejoren su pesquisa. El presente trabajo tiene por objeto la revisión de la literatura actual en cuanto a los métodos disponibles para su diagnóstico.

The laryngopharyngeal reflux is a common cause of morbidity of the upper aerodigestive tract. Despite its high prevalence, there is still controversy regarding the diagnostic accuracy of this disease and its pathophysiology and management. The current diagnostic test still have significant limitations, hence the interest arises to find fast and efficient methods to improve their research. This paper aims to review the current literature regarding available methods for diagnosis.

Acredita-se que haja uma associação entre síndrome da apneia obstrutiva do sono (SAOS) e refluxo laringofaríngeo (RLF). OBJETIVO: Estudar a prevalência de sintomas/sinais de refluxo em pacientes roncadores com suspeita de SAOS. MÉTODO: Estudo clínico corte transversal de 74 adultos Berlim positivo acompanhados em ambulatório de distúrbios do sono de centro universitário. As variáveis estudadas foram IMC, Epworth, índice de sintomas de refluxo (RSI) e escala de achados endolaríngeos de refluxo (RFS), bem como seus subdomínios que podem traduzir maior inflamação. Correlações entre questionários de sono e escalas de refluxo, bem como seus subdomínios, foram feitas com significância estabelecida em p < 0,05. RESULTADOS: Noventa e oito porcento dos pacientes apresentaram sintomas e sinais sugestivos de RLF, sendo esta prevalência significativamente maior nos obesos (p = 0,002). CONCLUSÃO: A diferença significativa nos sinais inflamatórios sugestivos de RLF entre obesos e não obesos com suspeita de SAOS sugere que a obesidade pode interferir nos achados inflamatórios na faringe e laringe. A altíssima prevalência destes sintomas e sinais de refluxo nos pacientes com suspeita de SAOS demonstra a importância de aprofundar estudos nesta área. .

OBJECTIVE: To study the prevalence of signs and symptoms of reflux in snorers with suspected OSA. METHOD: This cross-sectional study enrolled 74 patients assessed positive for OSA with the Berlin questionnaire. The subjects were followed up at the sleep disorder ward of a university center. Studied variables included the BMI, the Epworth sleepiness scale, the reflux symptom index (RSI), the reflux finding score (RFS), and their subdomains related to increased inflammation. The correlations between sleep questionnaires, reflux scales, and their subdomains were deemed statistically significant when p < 0.05. RESULTS: Ninety-eight percent of the subjects had symptoms and signs suggestive of LPR; prevalence was significantly higher among obese individuals (p = 0.002). CONCLUSION: The significant difference seen in the prevalence of signs of inflammation suggestive of LPR when obese and non-obese subjects with suspected OSA were compared indicates that obesity may affect inflammatory findings of the pharynx and larynx. The high prevalence of symptoms and signs of reflux in patients with suspected OSA calls for more studies on the matter. .

A doença do refluxo gastroesofágico é decorrente do fluxo retrógrado de secreção cloridropéptica para o esôfago e órgãos adjacentes, causando um espectro variável de lesões e sintomas. Sua incidência vem aumentando nos últimos anos e sua prevalência estimada na população brasileira é de cerca de 12%. A DRGE tem como manifestações típicas a pirose e a regurgitação, podendo se apresentar com queixas extraesofágicas tais como asma, tosse crônica, dor torácica não cardíaca e sintomas otorrinolaringológicos.

Gastro-oesophageal reflux disease is caused by the retrograde flow of gastric acid-peptic secretion into the esophagus and adjacent organs, causing a variable spectrum of lesions and symptoms. Its incidence has been increasing in recent years and its estimated prevalence in the Brazilian population is about 12%. Typical manifestations of GERD are heartburn and regurgitation, but the disease may present with extraesophageal complaints such as asthma, chronic cough, non-cardiac chest pain and ENT symptoms.

A saliva é fundamental para a homeostase digestiva. Alterações no seu volume e composição são correlacionadas com o refluxo laringofaríngeo (RLF). Estudos recentes demonstraram que pacientes com RLF apresentam acidificação do pH salivar. A síndrome de Sjögren (SS) foi eleita como modelo de hiposalivação, com objetivo de analisar as repercussões da diminuição salivar na laringe e faringe. CASUÍSTICA E MÉTODO: Estudo clínico transversal de 19 sujeitos com SS e RLF comparados com 12 indivíduos saudáveis. Obtidas amostras de saliva total não estimulada (STNE) e saliva total estimulada por mastigação de parafilm M® (STE). RESULTADOS: Todos os indivíduos eram mulheres, média de idade de 60 anos (estudo) e 44 anos. A prevalência de RLF foi 100 por cento. O pH médio na STNE foi 7,53 (grupo estudo) e 7,57(controle), aumentando para 7,87 e 7,93, respectivamente, após estimulação mecânica. Não houve diferença significante de pH entre os grupos. O volume salivar médio dos pacientes com SS foi 1,27mL (STNE) e 3,78mL (STE), sendo o volume salivar do grupo controle significativamente maior (4,02mL na STNE e 11,96mL na STE). CONCLUSÕES: Todos os indivíduos estudados apresentaram RLF, fato provavelmente relacionado à queda uniforme observada no volume salivar e de todos seus componentes, não sendo observadas mudanças no pH salivar no grupo estudado. Isso sugere fisiopatogenias diferentes do RLF para indivíduos com SS.

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.

La semiología digestiva pediátrica, al igual que todos los sistemas del cuerpo humano, incluyen la Inspección, la Auscultación, la Palpación y la Percusión del abdomen y sus órganos anexos. La historia clínica continúa siendo la principal herramienta con que contamos para orientar el diagnóstico y así proponer un plan terapéutico y de promoción y prevención, con el fin de evitar comorbimortalidades posibles. El presente artículo revisa algunas de las patologías más frecuentes que afectan el sistema gastrointestinal, hepático y nutricional en niños.

The pediatric gastrointestinal symptomatology, like all human body systems, including inspection, auscultation, palpation and percussion of the abdomen and its organs annexes. The clinical history remains the main tool we have to guide the diagnosis and thus to propose a treatment plan and health promotion and prevention, in order to avoid possible co morbilities and mortalities. This article reviews some of the most common diseases affecting the gastrointestinal system, liver and nutrition in children.

La enfermedad por reflujo gastroesofágico (ERGE) es un trastorno gastrointestinal frecuente que representa una de las causas de consulta más común en medicina general y gastroenterología. Recientemente, se ha descrito que la ERGE puede asociarse a manifestaciones otorrinolaringológicas como laringitis, tos crónica, odinofagia, escurrimiento nasal posterior y asma. En su fisiopatología se involucran mecanismos directos e indirectos, considerándose al ácido como el agente más nocivo, aunque otras sustancias pueden lesionar las estructuras laríngeas como pepsina, moco y contenidos duodenales. El diagnóstico de ERGE laríngeo se basa en la realización cuestionarios específicos, laringoscopia y la pHmetría ambulatoria de 2 canales. Independientemente del método diagnóstico empleado, cuando se asume que la ERGE es causa de síntomas laríngeos, en la actualidad el uso de medicamentos que suprimen el acido (especialmente IBPs) constituye la piedra angular del tratamiento, aunque los resultados clínicos sobre su efectividad son muy controversiales. En la presente revisión se analizan los aspectos más controversiales respecto a la fisiopatología, diagnóstico y tratamiento de las manifestaciones laríngeas de la ERGE...

Gastro-esophageal reflux disease (GERD) is a frequent gastrointestinal disorder that has became one of the most common conditions presenting in general and gastroenterology practice. Recently, it has been described that GERD may have otolaryngological manifestations such as laryngitis, chronic cough, odynophagia, posterior nasal drip and asthma. Several patophysiological mechanisms have been described, but abnormal acid exposure is the most important. However, there is evidence that other substances can damage laryngeal structures, such as pepsin, mucus and duodenal content). Laryngeal GERD is diagnosed by using specific questionnaires, or by the presence of laryngeal signs in the laryngoscopy or by the detection of abnormal acid exposure using a dual ambulatory pH monitoring. Suppressive acid secretion drugs (specifi cally PPI´s) represent the gold standard therapy when laryngeal symptoms are related to GERD. However, the evidence regarding the effectiveness of PPI´s in laryngeal GERD are controversial. In this review, we analyze the most relevant issues regarding the pathophysiology, diagnosis and treatment of laryngeal GERD...

A doença do refluxo gastroesofágico tem duas manifestações clínicas distintas reconhecidas: o refluxo gastroesofágico clássico e o refluxo laringofaríngeo (RLF) com sintomas respiratórios e/ou laríngeos que acabam trazendo os pacientes à atenção do otorrinolaringologista. O diagnóstico desta modalidade de refluxo é feito pela história e exame laringoscópico sugestivos, podendo ser confirmado pela PH-metria esofágica ambulatorial de 24 horas com dois canais, um distal e um proximal no nível do esfíncter esofagiano superior. No entanto, por não haver padronização adequada para a interpretação deste exame no RU, podem ocorrer falsos negativos. Objetivo: O objetivo deste estudo foi analisar os exames de pH-metria de pacientes com sintomas e sinais de RLF, para avaliar a sensibilidade deste exame para diagnóstico da doença. Material e método: Foram estudados 20 pacientes adultos com diagnóstico clínico e laringoscópico, de RLF submetidos a PH-metria esofágica de 24 horas de dois canais. Resultados: Apenas 25% dos exames foram positivos, segundo o relatório do examinador. Em análise minuciosa dos traçados do exame, outros nove pacientes mostraram episódios de refluxo proximal que não haviam sido considerados patológicos, perfazendo um total final de 70% de positividade. Os seis pacientes com PH-metria normal tinham grau leve ou moderado de RLF. Discussão e conclusões: Os autores discutem as dificuldades de interpretação da PH-metria esofágica de 24 horas de dois canais e alertam para a importância de uma padronização deste exame.

Gastroesophageal reflux disease may manifest in two distinct clinical forms: classical gastroesophageal reflux (GER) and laryngopharyngeal reflux (LPR). Diagnosis of the latter form is made by a suspicious history associated to typical laryngeal findings, which may be confirmed by a 24-hour double probe esophageal pH-metry. Aim: This study was designed to compare the results of the above mentioned diagnostic test on patients with clinical and laryngoscopic suspicion of LPR. Material and methods: Twenty adult patients with clinical and laryngoscopic diagnosis of reflux laryngitis were submitted to 24-hour ambulatory double probe esophageal PH-monitoring for confirmation of the diagnosis. Results: It was found that only 25% of patients presented with a positive test according to the interpretation of the examiner, but when careful review of the, tracings was carried out an additional nine cases of pathological reflux at the proximal probe were found, totaling 70% of confirmed proximal reflux. The remaining patients were those with-mild or moderate symptoms and laryngeal-findings. Discussion and conclusions: The authors discuss the possible reasons for such a high rate of false-negative 24-hour double probe esophageal pH-metry in the current study and the need of creating parameters for the interpretation of this test.
