ABSTRACT
RESUMO Objetivo comparar os sintomas da cinetose provocados por estímulo de realidade virtual, em voluntários com e sem histórico da doença. Métodos estudo analítico qualitativo e quantitativo, observacional transversal, prospectivo, realizado com voluntários com e sem histórico de cinetose, submetidos à imersão em realidade virtual com o uso de óculos de realidade aumentada. Antes e após a estimulação sensorial, o participante tinha a frequência respiratória (FR), a frequência cardíaca (FC) e pressão arterial sistólica (PAs) e diastólica (PAd) medidas. No primeiro dia, o voluntário foi exposto a um vídeo que simulava uma pessoa dentro de um carro, com predomínio de fluxo visual lateral. Após uma semana, uma animação de montanha russa, com predomínio de fluxo visual frontal. Durante a estimulação sensorial de dez minutos, uma nota de 0 a 10 era dada a cada 30 segundos para a intensidade do desconforto sentido pelo participante. Após, um questionário foi realizado para avaliação dos sintomas de cinetose. Resultados indivíduos com cinetose apresentaram maior intensidade de sintomas, tanto no experimento do carro (p=0,026), como na montanha russa (p=0,035). Não houve correlação entre cinetose e as variáveis FC, FR e PA. Os pacientes com cinetose atribuíram maiores notas de desconforto no curso das experiências, principalmente na experiência da montanha russa. Conclusão indivíduos com cinetose apresentam sintomas mais intensos quando submetidos a estímulos por realidade virtual, se comparados a indivíduos sem a doença.
ABSCTRACT Purpose to compare the symptoms of motion sickness caused by virtual reality stimulation in volunteers with and without history of the disease. Methods qualitative and analytical, observational, cross-sectional, and prospective study, approved by Research Ethics Committee, 3.443.429/19, with volunteers with and without history of motion sickness who were subjected to immersion in VR with the use of virtual reality glasses. Before and after sensory stimulation, the participant had respiratory rate (RF), heart rate (HR) and systolic blood pressure (PAs) and diastolic blood pressure (PAd) measured. On the first day, the volunteer was exposed to a video that simulated a person in a car, with a predominance of lateral visual flow. A week later, an animation of a roller coaster, with a predominance of frontal visual flow. During the 10-minute experiment, a score from 0 to 10 was given every 30 seconds for the intensity of the discomfort felt by the volunteer. A post-questionnaire was conducted to assess motion sickness symptoms. Results individuals with motion sickness history had a higher intensity of symptoms in the car (p = 0.026) and roller coaster experiment (p = 0.035). There was no correlation between motion sickness and the variables HR,FR,PA. Patients with motion sickness gave higher scores of discomfort throughout the experiments, mainly in the roller coaster experience. Conclusion individuals with motion sickness present more intense symptoms when subjected to stimuli by VR compared to controls without disease.

Abstract Introduction: Endolymphatic hydrops is the pathophysiological substrate of Ménière's disease. The changes in the inner ear, transmitted to the middle ear through changes in the ossicular chain mobility, can be quantified by wideband tympanometry, through the measurement of the acoustic absorbance at multiple frequencies, represented by the sound energy absorbed by the middle ear, even at its early stages. Studying the behavior of the middle ear through the absorbance in patients with endolymphatic hydrops under ambient pressure and under peak pressure can be useful for detecting Ménière's disease. Objective: To characterize acoustic absorbance behavior in subjects with symptomatic and asymptomatic Ménière's disease compared to controls, in order to verify the ability of wideband tympanometry to detect Ménière's disease. Methods: We carried out a cross-sectional study with a diagnostic approach comparing the findings of wideband tympanometry at ambient pressure and peak pressure between the ears of the control group (n = 30), the asymptomatic group (n = 21) and the symptomatic group (n = 9). Results: Different peak pressure values were found between the ears of the control group (0daPa), the asymptomatic group (−11 daPa) and the symptomatic group (−192 daPa), with p < 0.05 by the Kruskal-Wallis test, Mann Whitney test and Bonferroni correction. Different absorbance values were found between the ears of the symptomatic group and the asymptomatic group compared to the control group for low frequencies at ambient pressure and peak pressure, with p < 0.05 by the Kruskal-Wallis test, Mann Whitney test and Bonferroni correction. Conclusions: The Wideband Tympanometry test was capable of identifying the presence of Ménières disease, and to differentiate between asymptomatic and symptomatic patients, when comparing them with healthy individuals.
Resumo Introdução: A hidropsia endolinfática é o substrato fisiopatológico da doença de Ménière. As alterações desencadeadas na orelha interna, transmitidas à orelha média pelas modificações na mobilidade da cadeia ossicular, podem ser quantificadas pela timpanometria de banda larga, através da medida da absorvância acústica sob múltiplas frequências, representadas pela energia sonora absorvida pela orelha média, mesmo em estágios iniciais de sua instalação. Estudar o comportamento da orelha média através da absorvância em pacientes com hidropisia endolinfática sob pressão ambiente e sob o pico de pressão pode ser útil na detecção da doença de Ménière. Objetivo: Caracterizar o comportamento da absorvância em indivíduos com diagnóstico da doença de Ménière sintomáticos e assintomáticos, comparados com controles, a fim de verificar a capacidade da timpanometria de banda larga em detectar variações clínicas relacionadas a possível hidropisia endolinfática. Método: Foi realizado um estudo transversal, com enfoque diagnóstico, que comparou os achados da timpanometria de banda larga na pressão ambiente e no pico de pressão entre orelhas do grupo controle (n = 30), grupo assintomático (n = 21) e grupo sintomático (n = 9). Resultados: Foram encontrados valores do pico de pressão diferentes entre orelhas do grupo controle (0 daPa), do grupo assintomático (-11 daPa) e do grupo sintomático (-192 daPa), com p <0,05 pelos testes de Kruskal-Wallis, Mann Whitney e correção de Bonferroni. Foram encontrados valores de absorvância diferentes entre orelhas do grupo sintomático e do grupo assintomático em relação ao grupo controle para as frequências baixas na pressão ambiente e na pressão de pico, com p < 0,05 pelos testes de Kruskal-Wallis, Mann Whitney e correção de Bonferroni. Conclusão: A timpanometria de banda larga foi um teste capaz de identificar a presença da doença de Ménière e de diferenciar os pacientes assintomáticos e sintomáticos, comparando-os com indivíduos hígidos.

RESUMO Objetivo avaliar se a posturografia, exame que avalia a habilidade de manter o equilíbrio em condições sensoriais conflitantes, pode identificar risco de queda em idosos com tontura. Métodos comparar os resultados posturográficos de idosos com e sem história de quedas, pareados por gênero, idade e diagnóstico etiológico da tontura. Resultados dezoito idosos com quedas - 4 com único episódio e 14 com história de 2 ou mais quedas no último ano - foram comparados com 18 idosos sem quedas, pareados por gênero, idade e diagnóstico etiológico. Pacientes com quedas apresentaram resultados piores para as análises de dependência visual (p=0,04, p=0,01, p=0,03). Pacientes com quedas recorrentes (2 ou mais episódios) apresentaram piores resultados em diversas condições sensoriais: somatossensorial, vestibular, dependências visuais e índice de equilíbrio composto. Conclusão a posturografia mostrou-se útil na identificação de idosos com quedas, principalmente em indivíduos com quadros recorrentes.
ABSTRACT Purpose the aim of this study is to determine whether posturography, an exam used to investigate the ability to maintain balance under conflicting sensory conditions, can identify the risk of falls in eldery patients with dizziness. Methods to compare the posturographic results of elderly people with falls vs elderly people with no falls, paired by sex, age and dizziness etiology. Results 18 fallers, and, of these, 14 with two or more falls in the last year were compared with 18 elderly people without falls. Comparing subjects without falls vs subjects with at least one fall in the last year, fallers obtain worse scores in conditions of visual dependence. Comparing non fallers with subjects with two or more falls, people with recurrent falls obtain worse score in several conditions: somatosensorial, vestibular, visual conflict, and in the main measure, the composite score. Conclusion posturography appears to be a useful tool to identify those at high risk of recurrent falls.

Abstract Introduction: Neurotology is a rapidly expanding field of knowledge. The study of the vestibular system has advanced so much that even basic definitions, such as the meaning of vestibular symptoms, have only recently been standardized. Objective: To present a review of the main subjects of neurotology, including concepts, diagnosis and treatment of Neurotology, defining current scientific evidence to facilitate decision-making and to point out the most evidence-lacking areas to stimulate further new research. Methods: This text is the result of the I Brazilian Forum of Neurotology, which brought together the foremost Brazilian researchers in this area for a literature review. In all, there will be three review papers to be published. This first review will address definitions and therapies, the second one will address diagnostic tools, and the third will define the main diseases diagnoses. Each author performed a bibliographic search in the LILACS, SciELO, PubMed and MEDLINE databases on a given subject. The text was then submitted to the other Forum participants for a period of 30 days for analysis. A special chapter, on the definition of vestibular symptoms, was translated by an official translation service, and equally submitted to the other stages of the process. There was then a in-person meeting in which all the texts were orally presented, and there was a discussion among the participants to define a consensual text for each chapter. The consensual texts were then submitted to a final review by four professors of neurotology disciplines from three Brazilian universities and finally concluded. Based on the full text, available on the website of the Brazilian Association of Otorhinolaryngology and Cervical-Facial Surgery, this summary version was written as a review article. Result: The text presents the official translation into Portuguese of the definition of vestibular symptoms proposed by the Bárány Society and brings together the main scientific evidence for each of the main existing therapies for neurotological diseases. Conclusion: This text rationally grouped the main topics of knowledge regarding the definitions and therapies of Neurotology, allowing the reader a broad view of the approach of neurotological patients based on scientific evidence and national experience, which should assist them in clinical decision-making, and show the most evidence-lacking topics to stimulate further study.

O estudo do sistema vestibular tem avançado tanto que mesmo definições básicas, como o significado dos sintomas vestibulares, foram apenas recentemente padronizadas. Objetivo: Apresentar uma revisão dos principais assuntos da otoneurologia, inclusive conceitos, diagnóstico e tratamento da otoneurologia, definir a evidência científica atual para facilitar a tomada de decisões e demonstrar as áreas mais carentes de evidência para estimular novas pesquisas. Método: Este texto é fruto do I Fórum Brasileiro de Otoneurologia, que reuniu os principais pesquisadores brasileiros dessa área para uma revisão da literatura. Serão feitos três trabalhos de revisão a serem publicados. Este primeiro abordou as definições e as terapias, o segundo abordará as ferramentas diagnósticas e o terceiro definirá os principais diagnósticos. Cada autor fez um levantamento bibliográfico na base de dados da Lilacs, SciELO, Pubmed e Medline de um determinado assunto. O seu texto foi então submetido aos demais participantes do Fórum por 30 dias para análise. Um capítulo especial, da definição dos sintomas vestibulares, foi traduzido por serviço de tradução oficial e igualmente submetido às demais etapas do processo. Houve então uma reunião presencial em que todos os textos foram apresentados oralmente e houve uma discussão entre os participantes para a definição de um texto consensual para cada capítulo. Os textos consensuais foram então submetidos a uma revisão final por quatro professores de otoneurologia de três universidades brasileiras e, por fim, finalizado. A partir do texto completo, publicado no site da Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, foi escrita esta versão-resumo como artigo de revisão. Resultado: O texto apresenta a tradução oficial para o português da definição dos sintomas vestibulares propostos pela Barany Society e agrupa as principais evidências científicas para cada um das principais terapias existentes para as doenças otoneurológicas. Conclusão: Este texto agrupou de forma racional os principais tópicos de conhecimento a respeito das definições e terapias da otoneurologia, permite ao leitor uma visão ampla da abordagem dos pacientes otoneurológicos baseada em evidências científicas e experiência nacional, que deverá auxiliá-lo na tomada de decisões clínicas, e mostra os assuntos mais carentes de evidência para estimular novos estudos.

Facial nerve hemangioma is a rare and benign vascular tumor, and accounts for 0.7% of intratemporal tumors. We report the second case described in the literature of a facial nerve hemangioma in its tympanic segment. A 14-year-old male patient presented with a history of progressive right ear hearing loss with preserved facial mimicry. Pure tone audiometry showed a right ear moderate conductive hearing loss. Magnetic resonance imaging demonstrated an expansive lesion involving the tympanic segment of the right facial nerve, suggestive of hemangioma. Watchful waiting was chosen as management. In the first case of middle ear facial hemangioma described in the literature, facial palsy was the symptom that led the patient to seek medical care. In the present case, it can be inferred that the first symptom was conductive hearing loss ipsilateral to the lesion. Facial palsy may not be present and the clinical presentation may resemble otosclerosis, ossicular chain disruption, and third window abnormalities, among other differential diagnoses of conductive hearing loss. The second case of tympanic portion facial nerve hemangioma is reported, describing the specificity of conductive hearing loss as its only clinical manifestation.

RESUMO O hemangioma do nervo facial é um tumor vascular raro e benigno, que corresponde a 0,7% dos tumores intratemporais. Apresentamos o segundo caso descrito na literatura de hemangioma do nervo facial em sua porção timpânica. Paciente de 14 anos, sexo masculino, apresentando hipoacusia progressiva em orelha direita com mímica facial preservada. A audiometria evidenciou perda condutiva moderada à direita. A ressonância magnética demonstrou lesão expansiva, comprometendo o segmento timpânico do nervo facial direito, sugestiva de hemangioma do nervo facial. A conduta foi expectante. No primeiro caso descrito na literatura de hemangioma do facial em orelha média, o sintoma que levou o paciente ao atendimento médico foi paralisia facial. No presente caso, pode-se inferir que o primeiro sintoma foi a perda auditiva condutiva ipsilateral à lesão. A paralisia facial pode não estar presente, e o quadro clínico pode se assemelhar à otosclerose, disjunção de cadeia e síndrome da terceira janela, dentre outros diagnósticos diferenciais de perdas auditivas condutivas. O artigo relata o segundo caso de hemangioma do nervo facial em sua porção timpânica, mostrando a peculiaridade de perda auditiva condutiva como única manifestação clínica.

UNLABELLED: Dizziness is frequent in elderly people. AIMS: To evaluate the Quality of Life (QoL) in elderly subjects with dizziness, relate it with gender and age. MATERIAL AND METHOD: A prospective study comprising 120 elderly patients with dizziness evaluated with Brazilian versions of the Whoqol-bref and the dizziness handicap inventory (DHI). The factor analysis (FA), the Mann Whitney and Kruskal Wallis tests, and the Spearman correlation were applied to study the results. RESULTS: The most compromised domains were the DHI physical domain and the Whoqol-bref physical and environment domains. FA resulted in 3 factors in the DHI and 5 factors in the Whoqol-bref. There was a moderate correlation (-0.596) in the total scores of both instruments. Males had a better QoL in the "environment perception and introspectivity" and "health perception" factors of the Whoqol-bref test. Females had a better QoL in the "functionality perception" factor of the Whoqol-bref test. There were no significant age differences. CONCLUSIONS: Elderly patients with dizziness have a worse QoL. Elderly females with dizziness have worse QoL scores in "environment perception and introspectivity" and "health perception" and better QoL in the "functionality perception" factor compared to elderly males.

Tontura é muito frequente em idosos. OBJETIVOS: Avaliar a qualidade de vida (QV) em idosos vestibulopatas e relacioná-la com o gênero e a faixa etária. MATERIAL E MÉTODO: Estudo prospectivo que incluiu série de 120 casos de idosos com tontura que foram avaliados por meio das versões brasileiras dos questionários Whoqol-bref e Dizziness Handicap Inventory (DHI). Os resultados obtidos foram submetidos à Análise Fatorial (AF) e aos testes de Mann Whitney, Kruskal Wallis e correlação de Spearman. RESULTADOS: O domínio físico avaliado pelo DHI, e o físico e o ambiental do Whoqol-bref foram os mais comprometidos. A AF resultou em 3 fatores no DHI e 5 no Whoqol-bref: Houve moderada correlação (-0,596) entre o escore total de ambos os instrumentos. Os homens apresentaram melhor QV nos fatores "percepção ambiental e introspectividade" e "percepção da saúde" do Whoqol-bref. As idosas obtiveram melhor QV no fator "percepção da funcionalidade" do Whoqol-bref. Não houve diferenças significantes entre os fatores dos dois instrumentos por faixa etária. CONCLUSÕES: Idosos vestibulopatas apresentam QV prejudicada. As idosas vestibulopatas apresentam pior QV em relação aos fatores "percepção ambiental e introspectividade" e "percepção da saúde" e melhor QV em relação ao fator "percepção da funcionalidade" que os homens.

UNLABELLED: Although Bell's palsy is the major cause of acute peripheral facial palsy, its pathogenesis remains unknown. Reactivation of the varicella zoster virus has been implicated as one of the main causes of Bell's palsy, however, studies which investigate the varicella zoster virus reactivation in Bell's palsy patients are mostly Japanese and, therefore, personal and geographic characteristics are quite different from our population. AIMS: To determine varicella zoster virus frequency in saliva samples from patients with Bell's palsy, using PCR. MATERIAL AND METHOD: One hundred seventy one patients with acute peripheral facial palsy were prospectively enrolled in this study. One hundred twenty were clinically diagnosed with Bell's palsy, within one week of onset of the disease and no previous anti-viral therapy. We had 20 healthy adults as controls. Three saliva samples were collected from patients and controls at initial examination and at one and two weeks later. The detection of the varicella zoster virus DNA was performed using PCR. RESULTS: Varicella zoster virus was detected in two patients (1.7%). The virus was not identified in saliva samples from the controls. CONCLUSIONS: Varicella zoster virus was detected in 1.7% of saliva samples from patients with Bell's palsy, using PCR.

Embora a paralisia de Bell seja o tipo mais frequente de paralisia facial periférica,sua causa ainda é objeto de inúmeros questionamentos. A reativação do vírus varicela zoster tem sido considerada uma das principais causas da paralisia de Bell, porém, os poucos trabalhos que estudam a prevalência do VVZ como agente etiológico da PB são japoneses, o que determina características geográficas e populacionais bastante díspares de nossa população. OBJETIVOS: Verificar a frequência do vírus varicela zoster em saliva de indivíduos com PB, pela técnica de PCR. MATERIAL E MÉTODO: Estudo prospectivo com 171 pacientes com PFP, sendo 120 pacientes portadores de paralisia de Bell, com até uma semana de evolução, sem uso prévio de drogas antivirais. O grupo controle foi composto de 20 adultos sadios. Nestes indivíduos foram coletadas três amostras de saliva em semanas consecutivas, para pesquisa de DNA viral pela técnica de PCR. RESULTADOS: O vírus varicela zoster foi encontrado em amostras de saliva de dois pacientes com paralisia de Bell (1,7 por cento). Nenhum vírus foi identificado no grupo controle. CONCLUSÃO: Foi verificada frequência de 1,7 por cento para vírus varicela zoster em amostras de saliva de pacientes com paralisia de Bell, pela técnica de PCR.

UNLABELLED: A longitudinal cohort study Introduction: Voice change may be defined as a group of changes in voice pattern that take place between childhood and puberty. During this period some vocal cord lesions (specifically cysts and nodules) may undergo transformation. AIM: To evaluate changes in vocal cord structural lesions following voice changes. MATERIAL AND METHOD: All laringoscopic exams made at the Sao Paulo Santa Casa de Misericordia between 1997 and 2002 of children aged below 10 years with structural lesions were reevaluated. Children whose voice had already changed repeated the exam and answered a questionary about voice change. RESULTS: Eleven children were studied. Observation showed that hoarseness was significantly decreased after voice change, and that lesions revealed modifications. Thickened-like lesions were reabsorved, and protrusion-like lesions underwent modification but did not disappear. CONCLUSION: The definition of lesions and subsequent modifications after voice change are important to define the correct approach to children presenting hoarseness.

Estudo de coorte contemporânea longitudinal. A muda vocal pode ser definida como um conjunto de mudanças no padrão da voz, que ocorreria entre a infância e a puberdade. Neste período, algumas lesões das pregas vocais, mais especificamente os cistos e nódulos, podem sofrer transformações. OBJETIVO: Avaliar as modificações que a muda vocal determinou nas pregas vocais de crianças com alterações estruturais, como nódulos, cisto ou sulco. MATERIAL E MÉTODO: Foram reavaliados todos os exames de videolaringoscopia ou nasofibroscopia de crianças menores de dez anos que apresentavam alterações estruturais nas pregas vocais, nódulos, cistos, ou sulcos realizados no ambulatório de laringologia da Santa Casa de Misericórdia de São Paulo, durante o período de 1997 a 2002. Destas crianças, todas as que já tinham passado pela muda vocal foram convocadas para repetir o exame e responder a um questionário referente à muda. RESULTADOS: Foram avaliadas onze crianças nas quais observou-se expressiva diminuição da queixa de disfonia após a muda. As lesões tipo espessamento tenderam a ser reabsorvidas e as lesões tipo abaulamento sofreram transformações sem desaparecer. CONCLUSÃO: A caracterização da lesão e das conseqüentes modificações que ocorrem com a muda são fundamentais na conduta frente uma criança com disfonia.
