RESUMEN
OBJECTIVE: To establish if the Reflux Symptom Index (RFI) and the Reflux Finding Score (RFC) can help establish the differential diagnosis in patients with distinct causes of chronic laryngopharyngitis. METHODS: A group of 102 adult patients with chronic laryngopharyngitis (Group A - 37 patients with allergic rhinitis; Group B - 22 patients with Obstructive Sleep Apnea (OSA); Group C - 43 patients with Laryngopharyngeal Reflux (LPR)) were prospectively studied. Chronic laryngitis was diagnosed based on suggestive symptoms and videolaryngoscopic signs (RSIâ¯≥â¯13 and RFSâ¯≥â¯7). Allergies were confirmed by a positive serum RAST, OSA was diagnosed with a positive polysomnography, and LPR with a positive impedance-PH study. Discriminant function analysis was used to determine if the combination of RSI and RFS scores could differentiate between groups. RESULTS: Patients with respiratory allergies and those with LPR showed similar and significantly higher RSI scores when compared to that of patients with OSA (pâ¯<â¯0.001); Patients with OSA and those with LPR showed similar and significantly higher RFS scores when compared to that of patients with Respiratory Allergies (OSA vs. Allergies pâ¯<â¯0.001; LPR vs. Allergies pâ¯<â¯0.002). The combination of both scores held a higher probability of diagnosing OSA (72.73%) and Allergies (64.86%) than diagnosing LPR (51.16%). CONCLUSIONS: RSI and RFS are not specific for reflux laryngitis and are more likely to induce a false diagnosis if not used with diligence.

RESUMEN
Abstract Introduction: Studies assessing the management of laryngopharyngeal reflux by otolaryngologists have reported an important heterogeneity regarding the definition, diagnosis, and treatment, which leads to discrepancies in the management of the patient. Information about the current knowledge and practices of Brazilian otolaryngologists in laryngopharyngeal reflux is lacking. Objective: To investigate the trends in management of laryngopharyngeal reflux disease among Brazilian otolaryngologists. Methods: A survey was sent by email to the members of the Brazilian Association of Otolaryngology-Head Neck Surgery. This survey has initially been conducted by the laryngopharyngeal reflux study group of young otolaryngologists of the International Federation of Otolaryngological Societies. Results: According to the survey responders, the prevalence of laryngopharyngeal reflux was estimated to be 26.8% of patients consulting in otolaryngology and the most common symptoms were globus sensation, throat clearing, cough and stomach acid reflux. Nasal obstruction, Eustachian tube dysfunction, acute and chronic otitis media, vocal fold nodules and hemorrhage were considered not associated with laryngopharyngeal reflux by the majority of responders. About 2/3 of Brazilian otolaryngologists based the diagnosis of laryngopharyngeal reflux on the assessment of both symptoms and findings and a positive response to empiric therapeutic trials. Proton pump inhibitor utilized once or twice daily, was the most commonly used therapeutic scheme. Only 21.4% of Brazilian otolaryngologists have heard about nonacid and mixed laryngopharyngeal reflux and the awareness about the usefulness of multichannel intraluminal impedance pH monitoring (MII-pH) was minimal; 30.5% of responders did not consider themselves as well-informed about laryngopharyngeal reflux. Conclusion: Although the laryngopharyngeal reflux-related symptoms, main diagnostic and treatment approaches referred by Brazilian otolaryngologists are consistent with the literature, the survey identified some limitations, such as the insufficient awareness of the role of laryngopharyngeal reflux in many otolaryngological conditions and of the possibility of non-acid or mixed reflux in refractory cases. Future studies are needed to establish international recommendations for the management of laryngopharyngeal reflux disease.
Resumo Introdução: Estudos que avaliaram o manejo do refluxo laringofaríngeo por otorrinolaringologistas mostraram uma importante heterogeneidade em relação à definição, diagnóstico e tratamento, o que leva a discrepâncias no tratamento do paciente. Faltam informações sobre o conhecimento e as práticas atuais dos otorrinolaringologistas brasileiros sobre o refluxo laringofaríngeo. Objetivo: Investigar as tendências no manejo da doença do refluxo laringofaríngeo entre os otorrinolaringologistas brasileiros. Método: O questionário foi enviado por e-mail aos membros da Associação Brasileira de Otorrinolaringologia-Cirurgia de Cabeça e Pescoço. Esta pesquisa foi inicialmente conduzida pelo LPR Study Group of Young Otolaryngologists da International Federation of Otolaryngological Societies. Resultados: De acordo com os respondentes da pesquisa, a prevalência de refluxo laringofaríngeo foi estimada em 26,8% dos pacientes consultados e os sintomas mais comuns foram sensação de globus, pigarro, tosse e refluxo de ácido estomacal. Obstrução nasal, disfunção da trompa de Eustáquio, otite média aguda e crônica, nódulos nas pregas vocais e hemorragia foram considerados como não associados ao refluxo laringofaríngeo pela maioria dos respondentes. Cerca de 2/3 dos otorrinolaringologistas brasileiros basearam o diagnóstico de refluxo laringofaríngeo na avaliação dos sintomas e achados e na resposta positiva a testes terapêuticos empíricos. Inibidores de bomba de prótons uma ou duas vezes ao dia foi o esquema terapêutico mais usado. Somente 21,4% dos otorrinolaringologistas brasileiros já ouviram falar sobre refluxo laringofaríngeo não ácido e misto e o conhecimento sobre a utilidade do monitoramento de pH por impedância intraluminal multicanal foi mínimo; 30,5% dos respondentes não se consideraram tão bem informados sobre o refluxo laringofaríngeo. Conclusão: Embora os sintomas relacionados ao refluxo laringofaríngeo e as principais abordagens diagnósticas e terapêuticas referidas pelos otorrinolaringologistas brasileiros sejam consistentes com a literatura, a pesquisa identificou algumas limitações, como o conhecimento insuficiente do papel do refluxo laringofaríngeo em diversas condições otorrinolaringológicas e da possibilidade de refluxo não ácido ou misto em casos refratários. Estudos futuros são necessários para estabelecer recomendações internacionais para o manejo de doença do refluxo laringofaríngeo.
RESUMEN
This text is the continuation of the XVIII SBFa Congress publication. In part "A" we presented the analyses on clinical vocal evaluation. Part "B" focuses on vocal rehabilitation: 4. Traditional techniques of vocal therapy; 5. Modern techniques of electrostimulation and photobiomodulation applied to vocal rehabilitation. The numerous studies on the various programs, methods, and techniques of traditional rehabilitation techniques, and many with high quality of evidence, allow us to consider such procedures relatively well described, safe, and with known effects, accounting for the treatment of various vocal disorders. The scientific evidence with traditional techniques is recognized worldwide. New fronts of evolution, with electrostimulation or photobiomodulation used to handle voice problems, seem to be promising as coadjutant approaches. There are more studies on electrostimulation in vocal rehabilitation than with photobiomodulation; however, scientific evidence for these two modern techniques is still limited. Knowledge and caution are required for the application of either technique.

RESUMEN
INTRODUCTION: The diagnosis of laryngopharyngeal reflux is controversial. There is currently no gold standard, so it relies mainly on suspicious clinical symptoms and videolaryngoscopic findings. Unfortunately these signs and symptoms are common to other causes of chronic laryngitis. Scoring systems have been proposed to reduce subjectivity in clinical diagnosis. The most widely used and accepted is the Reflux Symptom Index, which has already been translated into over 10 other languages. OBJECTIVE: Study the psychometric properties of the Brazilian Portuguese version of the Reflux Symptom Index (Índice de Sintomas de Refluxo - ISR). METHODS: One hundred and fifty-four adults, 88 with laryngopharyngeal reflux and 66 healthy controls, were studied over a 6-month period, responding to the ISR after thoroughly investigated on possible other causes of chronic laryngitis and the presence of gastroesophageal disease. Test and retest reliability was addressed by reapplying the score to a random subgroup of 101 subjects. RESULTS: The ISR of subjects was significantly higher than that of controls (Student t test for independent samples, P < 0.001). The ISR also showed high temporal stability and reproducibility (ICC of 0.988 with a confidence interval of 0.982-0.992). The ISR at a cutoff of 13 points presented a sensitivity of 78.4%, a specificity of 95.4%, a false negative of 4.55%, a false positive of 21.59%, a positive predictive value of 95.83%, and a negative predictive value of 86.93%. CONCLUSION: The ISR proved to be a valid and reliable diagnostic tool.

INTRODUCTION: Laryngopharyngeal reflux (LPR) poses a diagnostic challenge. Clinical diagnosis, based on suggestive symptoms and laryngoscopic signs of inflammation, should be acceptable, as long as diligent differential diagnosis is sought. In order to minimize subjectivity, a number of diagnostic instruments have been proposed, being the most common the Reflux Symptom Index and the Reflux Finding Score (RFS). The latter has been translated into several languages including Portuguese, but it still has not been properly validated in this language. OBJECTIVE: To validate the Brazilian Portuguese version of the RFS. MATERIAL AND METHOD: For validity and internal consistency, 172 adults were studied (106 with LPR and 66 healthy controls). Flexible transnasal laryngoscopy images were randomly examined twice by each of the two experienced otolaryngologists with a 72-hour interval. Strict exclusion criteria were applied to avoid other possible known causes of chronic laryngitis. For assessment of reproducibility and temporal stability, a random sample of 108 subjects (53 patients and 55 controls) were tested and retested. RESULTS: A statistically significant difference was observed in the mean RFS between patients with LPR (10.26 ± 3.58) and controls (5.52 ± 1.34) (P < 0.001). The interclass correlation coefficient comparing test and retest for both raters was high (R1 = 0.956; R2 = 0.948). CONCLUSION: The Brazilian Portuguese version of the RFS proved to be a reliable and reproducible instrument for the diagnosis of LPR with a sensitivity of 82.08%, a specificity of 93.94%, a positive predictive value of 95.60%, and a negative predictive value was 76.54%.

STUDY OBJECTIVES: The aim of the current study was to test the hypothesis that there is a temporal correlation between reflux episodes and respiratory events in patients with laryngopharyngeal reflux and obstructive sleep apnea. METHODS: Adults with clinically diagnosed laryngopharyngeal reflux confirmed by two validated instruments (reflux symptom index ≥ 13 and reflux finding score ≥ 7) and obstructive sleep apnea (OSA) underwent full polysomnography with concomitant and synchronized multichannel intraluminal impedance-pH esophageal monitoring. The apnea-hypopnea and arousal indexes that occurred 15, 30, and 45 minutes before and after each reflux episode were recorded and compared to full-night apnea and hypopnea and arousal index. RESULTS: We studied 27 patients (14 males, age 51.7 ± 9.1 years, body mass index 32.4 ± 4.2 kg/m²) with laryngopharyngeal reflux (reflux symptom index 16 ± 2 and reflux finding score 12 ± 3) and OSA (apnea-hypopnea index = 32.3 ± 28.4 events/h). We evaluated 102 reflux episodes. Almost half of the reflux episodes occurred while awake (43.1%) and only five reflux episodes (4.9%) occurred during an obstructive respiratory event. The apnea and hypopnea and arousal indexes 15, 30, and 45 minutes before and after reflux episodes were lower than full-night apnea and hypopnea and arousal indexes, respectively. CONCLUSIONS: Among patients with well-established laryngopharyngeal reflux and OSA, there is no temporal association between reflux and obstructive respiratory events. Even though the data comprised a small sample size, it seems that a more complex mechanism is involved with these two highly prevalent diseases.

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.

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.

Introdução: A saliva exerce influência primordial na homeostase do sistema digestório, pelos seus componentes inorgânicos e pelos fatores de crescimento. Indivíduos com sindrome de Sjögren (SS) apresentam maior incidência da doença do refluxo gastroesofágico (DRGE) e do refluxo laringofaríngeo (RLF). Concentrações salivares diminuídas do fator transformador de crescimento alfa (TGF-α) foram observadas em doentes dispépticos, porém não há estudos em populações com SS e RLF. Objetivo: Comparar concentrações salivares do TGF-α; de indivíduos com SS e RLF a de controles saudáveis. Método: Trata-se de um estudo prospectivo controlado. Doze pacientes com SS e RLF e 11 indivíduos controles saudáveis tiveram amostras salivares espontâneas e estimuladas coletadas para estabelecer concentração de TGF-α. Resultados: A concentração salivar de TGF-α; foi estatisticamente maior no grupo estudo para ambas amostras. Este aumento foi confirmado nos sete indivíduos do grupo estudo que não apresentavam esofagite erosiva quando comparados ao grupo controle, porém não houve diferença estatística da concentração de TGF-α; entre pacientes do grupo estudo que apresentava mesofagite erosiva em comparação ao grupo controle. Conclusão: A concentração salivar de TGF-α; foi estatisticamente maior no grupo de indivíduos com SS e RLF, sem esofagite erosiva. .

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.

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. .

UNLABELLED: Multiple sclerosis is a neurological disease that involves swallowing disorders. Many studies have shown an association between neurological and swallowing performance, but results have been conflicting. OBJECTIVE: To identify the frequency of dysphagia in patients with multiple sclerosis and neurological indicators that can represent the performance of swallowing. METHOD: In this study (cross-sectional) 120 Multiple Sclerosis patients underwent Functional Assessment of Swallowing by flexible nasal-pharyngo-laryngoscopy and the results were compared with the scores of the rating scales: (Clinical Evolving Forms of Disease, Functional Disability Scale for and Scale Systems Extended Functional Disability [Kurtzke Expanded Disability Status Scale]). RESULTS: Dysphagia was found in 90% of patients. Among the clinical forms of the disease, the progressive forms (primary progressive and secondary progressive) were more frequently associated with severe dysphagia, while the relapsing-remitting form presented more often mild and moderate dysphagia. Regarding the Disability Scale for Functional Systems, cerebellar function, brainstem function and mental health were associated with dysphagia, especially in the severe form. Regarding the Extended Functional Disability Scale, higher scores were associated with severe dysphagia. CONCLUSION: Dysphagia is common in MS patients, especially in those with greater impairment of neurological functions.

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.

A esclerose múltipla é uma afecção neurológica que envolve distúrbios da deglutição. Muitos estudos têm mostrado associação entre o comprometimento neurológico e o desempenho da deglutição, porém, os resultados têm sido conflitantes. OBJETIVO: Identificar a frequência de disfagia nos pacientes com esclerose múltipla e os indicadores neurológicos que podem representar o desempenho da deglutição. MÉTODO: Neste estudo (estudo transversal), 120 pacientes com esclerose múltipla foram submetidos à avaliação funcional da deglutição por fibronasofaringolaringoscopia, cujos resultados foram comparados com a pontuação das escalas de classificação (Formas Clínicas Evolutivas da Doença, Escala de Incapacidade Funcional por Sistemas e Escala Ampliada de Incapacidade Funcional [Kurtzke Expanded Disability Status Scale]). RESULTADOS: A disfagia foi identificada em 90% dos pacientes. Dentre as formas clínicas, as formas progressivas (primária progressiva e secundária progressiva) apresentaram com maior frequência disfagia grave, enquanto a forma remitente-recorrente apresentou mais frequentemente disfagia leve e moderada. Em relação à Escala de Incapacidade Funcional por Sistemas, as funções cerebelares, do tronco encefálico e mental tiveram associação com a disfagia, especialmente na forma grave. Quanto à Escala Ampliada de Incapacidade Funcional, pontuações mais altas se associaram aos quadros graves de disfagia. CONCLUSÃO: A disfagia é frequente em pacientes com esclerose múltipla, especialmente naqueles com maior comprometimento das funções neurológicas.
