RESUMO
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.

RESUMO
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.
RESUMO
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.
O presente texto é a continuação da publicação referente ao XVIII Congresso da SBFa. Na parte "A" apresentamos análises sobre avaliação clínica vocal. O foco da parte "B" são aspectos de reabilitação vocal: 4. Técnicas tradicionais de terapia vocal; 5. Técnicas modernas de eletroestimulação e fotobiomodulação aplicadas à reabilitação. Os inúmeros estudos sobre os diversos programas, métodos ou técnicas tradicionais de reabilitação, muitos de elevada qualidade de evidência, permitem considerar tais procedimentos relativamente bem descritos, seguros e com efeitos conhecidos, dando conta do tratamento de diversos distúrbios vocais. As evidências científicas com as técnicas tradicionais são reconhecidas mundialmente. Novas frentes de evolução, como o uso da eletroestimulação ou fotobiomodulação em voz parecem ser promissoras como abordagens coadjuvantes. Há mais estudos sobre eletroestimulação em voz do que com fotobiomodulação, contudo, evidências científicas para essas duas técnicas modernas são ainda limitadas. Conhecimento e cautela são necessários para a aplicação de quaisquer técnicas.

Part "a" of this publication was associated with the consolidation of the analyses of the first three aspects. The trend in the perceptual-auditory judgment of vocal quality was related to the use of standard protocols. The acoustic evaluation of the vocal signal is accessible and can be done descriptively or by extraction of parameters, thus preferring multiparametric measures.

RESUMO
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%.

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.
