ABSTRACT

ABSTRACT Purpose: to describe the results of a neonatal hearing health program and verify whether there is an association between the presence of risk indicators for hearing loss and failure in the tests and diagnosis. Methods: a one-cohort, observational, retrospective study with secondary data contained in a spreadsheet concerning the family's sociodemographic condition, clinical history, and examination results of 7,800 participants who were submitted to hearing screening between 2010 and 2016. Absolute frequency and percentages were used in the description of the first and second stages. In the association between risk indicators and failures in the otoacoustic emissions, the odds ratio, confidence interval, and significance level at 0.5% were used. Results: the risk indicators in 8 out of the 12 infants presented with hearing loss were ototoxic medication and intensive care unit (ICU) stay, whereas the likelihood of failure in the otoacoustic emissions occurred along with 11 indicators. The likelihood of a diagnosis of hearing loss was 13 times greater when there was a risk indicator, 18 times greater when an ototoxic medication had been used, and 16.62 times greater when they stayed in ICUs. Conclusion: the results show that knowing the indicators leads to considering the actions the team in charge should take.


RESUMO Objetivo: descrever os resultados de um programa de saúde auditiva neonatal e verificar se há associação entre presença de indicador de risco para perda auditiva e falhas nos testes e no diagnóstico. Métodos: trata-se do estudo de uma coorte, observacional e retrospectiva, com dados secundários contidos em planilha eletrônica sobre condições sociodemográficas da família, história clínica e resultados dos exames de 7.800 participantes que realizaram a Triagem Auditiva, de 2010 a 2016. Na descrição da primeira e segunda etapa, utilizou-se frequência absoluta e valores percentuais. Na associação entre indicador de risco com falhas nas EOA, utilizaram-se Odds Ratio, Intervalo de Confiança e nível de significância 0,5%. Resultados: dos 12 lactentes com perda auditiva, oito apresentaram como indicador de risco, a medicação ototóxica e permanência em UTI, sendo que a chance de falhar nas EOA ocorreu com onze indicadores. A chance do diagnóstico de perda auditiva foi 13 vezes maior quando há indicador de risco, 18 vezes maior quando usou medicação ototóxica e 16,62 vezes maior com permanência em UTI. Conclusão: os resultados mostram que conhecer os indicadores levará à reflexão de ações a serem adotadas pela equipe responsável.

ABSTRACT

ABSTRACT Objective: to verify a possible association between hearing loss and dysphonia, arterial hypertension, diabetes mellitus, thyroid diseases, and noise complaints. Methods: a cross-sectional study involving 60 teachers, mean age 47.05 years. Pure-tone threshold audiometry was used to assess hearing, the voice questionnaire and voice acoustic evaluation were used for voice perception and quality, and the standardized questionnaire verified noise complaint and comorbidities. The statistical analysis was conducted with Mann-Whitney and Fisher's exact tests and multivariate linear regression. Results: there was a significant association between hearing loss and diabetes mellitus, hypertension, and thyroid disease (both p <0.0001), but there was no association between noise complaints and hearing loss in this population. The regression showed that dysphonia (p = 0.0311) and diabetes mellitus (p = 0.0302) are independent risk factors for hearing loss. A correlation was found between hearing loss and voice characteristics: roughness, breathiness, tension, and resonance. Conclusion: this study showed that hypertension and thyroid diseases are factors associated with hearing loss. In addition, dysphonia and diabetes mellitus are independent factors associated with hearing loss in teachers. These results show the need for policies aimed at promoting teachers' health.


RESUMO Objetivo: verificar possível associação da perda auditiva com disfonia, hipertensão arterial (HA), diabetes mellitus (DM), doenças da tireoide e queixas de ruído. Métodos: estudo transversal envolvendo 60 professores, média de idade de 47,05 anos. Foi avaliada a audição por meio da Audiometria tonal limiar, a percepção e qualidade vocal com o questionário vocal e a avaliação vocal acústica, enquanto a queixa de ruído e as comorbidades envolvidas foram investigadas com o questionário padronizado. A análise estatística utilizou os testes Ex-act de Mann Whitney, Fisher e regressão linear multivariada. Resultados: houve associação significante entre perda auditiva e DM, HA e doenças da tireoide (ambas p <0,0001), mas não foi encontrada associação entre queixa de ruído e perda auditiva nesta população. A regressão mostrou que as variáveis disfonia (p = 0,0311) e DM (p = 0,0302) são fatores de risco independentes para perda auditiva. Houve correlação entre perda auditiva e as características vocais rugosidade, soprosidade, tensão e ressonância. Conclusão: este estudo demostrou que HA e doenças da tireoide são fatores associados a perda auditiva, além disso a disfonia e DM se constituem em fatores associados independentes para a perda auditiva em professores. Estes resultados mostram a necessidade de políticas direcionadas a promoção da saúde do professor.

ABSTRACT

ABSTRACT Purpose: to survey the national and international literature on the impacts of the coronavirus infection on the auditory system. Methods: an integrative review with search in the BIREME, PubMed, Scopus, and Web of Sciences databases. Inclusion criteria: articles in Portuguese and English whose subject was the coronavirus infection and its effects on the auditory system. Exclusion criteria: information from books and/or chapters, letters to editors, review articles, experience reports. The search strategy was based on the following combined descriptors, respectively in Portuguese and English: "Infecções por coronavírus", "Audição", "Perda auditiva", "Coronavirus infections", "Hearing", "Hearing Loss". Results: out of 43 articles found, two approached the issue. The first study assessed 20 patients that tested positive for COVID-19, though asymptomatic, who underwent pure-tone threshold audiometry and otoacoustic emissions. A significant increase in the auditory thresholds at high frequencies and a smaller response amplitude in the transient evoked otoacoustic emissions of those who tested positive for COVID-19 were observed when compared to that of controls. The second study reported the case of an asymptomatic 35-year-old COVID-19 female patient, who complained of otalgia and tinnitus, after being contaminated. The pure-tone threshold audiometry and tympanometry indicated mild unilateral (right ear) conductive hearing loss, with a type B tympanometric curve on that side. Conclusion: the studies included in this review showed different consequences of COVID-19 on hearing, with possible impairments on the sensory and mechanical structures of the auditory system. The knowledge of COVID-19 is limited, and further studies on its real impact on the auditory system are necessary.


RESUMO Objetivo: realizar um levantamento da literatura nacional e internacional sobre os impactos da infecção por coronavírus no sistema auditivo. Métodos: revisão integrativa com pesquisa nas bases de dados Bireme, PubMed, Scopus e Web of Sciences. Critérios de inclusão: artigos em português e em inglês que tinham como tema a infecção por coronavírus e seus efeitos no sistema auditivo. Critérios de exclusão: informações de livros e/ou capítulos, cartas ao editor, artigos de revisões e de relatos de experiência. Para a estratégia de busca, utilizou-se a combinação dos descritores em português e em inglês, respectivamente: "Infecções por coronavírus", "Audição", "Perda auditiva", "Coronavirus infections", "Hearing", "Hearing Loss". Resultados: dos 43 artigos encontrados, dois abordaram o tema proposto. O primeiro estudo avaliou 20 pacientes que testaram positivo para COVID-19, porém assintomáticos, esses realizaram audiometria tonal liminar e emissões otoacústicas. Observou-se como resultado um aumento significativo dos limiares auditivos nas altas frequências e menor amplitude de resposta no exame de emissões otoacústicas evocadas por estímulo transiente, quando comparados ao grupo controle. O segundo estudo relatou o caso de uma paciente de 35 anos de idade com COVID-19 assintomática, que apresentou queixa de otalgia e zumbido após a contaminação. A audiometria tonal liminar e timpanometria indicaram perda auditiva do tipo condutiva de grau leve unilateral à direita com curva timpanométrica do tipo B deste lado. Conclusão: os estudos incluídos mostraram diferentes repercussões da COVID-19 na audição, com possíveis acometimentos nas estruturas sensoriais e mecânicas do sistema auditivo. O conhecimento sobre a COVID-19 é limitado e mais estudos primários sobre seu real impacto no sistema auditivo são necessários.

ABSTRACT

Abstract Objective: To analyze the results of the audiological evaluation of children with HIV and AIDS. Data collection: Systematic review carried out in May 2019 in the Web of Science, PubMed, SciELO, and Scopus databases. Case reports and original articles were included, with no limitationsregarding country or year of publication. Data synthesis: 278 articles were identified; 26 were included, in which HIV/AIDS was shown to be a risk factor for hearing loss (OR = 5.364; p = 0.00). The studies used different audiological exams, with varying methodologies. There was no difference regarding the type of hearing loss (p = 0.119). Conclusion: Longitudinal studies using the same type of examination at all stages are suggested, to allow better monitoring of the effects of HIV on the child's hearing,and studies that provide more methodological details. The knowledge of the influence of HIV on the child's auditory system may lead to the promotion of measures that minimize the prevalence of hearing loss, allow an early diagnosis and timely rehabilitation, so as not to compromise child development.


Resumo Objetivo: Analisar os resultados da avaliação audiológica de crianças com HIV e AIDS. Coleta dos dados: Revisão sistemática realizada em maio de 2019 nas bases Web of Science, Pubmed, SciELO e Scopus. Relatos de caso e artigos originais foram incluídos, sem limitação quanto ao país ou ano de publicação. Síntese dos dados: Foram identificados 278 artigos, sendo que 26 foram incluídos, nos quais o HIV/AIDS foi mostrado como fator de risco para perda auditiva (OR = 5.364; p = 0.00). Os estudos utilizaram diferentes exames audiológicos, com diferentes metodologias. Não houve diferença com relação ao tipo de perda auditiva (p = 0.119). Conclusão: Sugere-se estudos longitudinais usando o mesmo tipo de exame em todas as fases para possibilitar melhor acompanhamento dos efeitos do HIV na audição da criança e estudos que tragam mais detalhes metodológicos. O conhecimento da influência do HIV no sistema auditivo infantil pode levar à promoção de medidas que minimizem a prevalência da perda auditiva, possibilitem diagnóstico precoce e permita reabilitação em tempo hábil para não comprometer o desenvolvimento infantil.

ABSTRACT

RESUMO Objetivo Comparar a frequência de indicadores de risco em bebês nascidos pré-termo e a termo; analisar as possíveis relações entre a presença de risco para perda auditiva com variáveis socioeconômicas, demográficas, obstétricas e risco à linguagem. Método Trata-se de um estudo de coorte longitudinal com amostra de 87 bebês. Foram coletados dados gestacionais, obstétricos e sociodemográficos das mães e dos bebês. A classificação socioeconômica das famílias foi analisada por meio do Critério de Classificação Econômica Brasil. O risco à linguagem foi avaliado por meio dos Sinais Enunciativos de Aquisição da Linguagem e Teste Denver II. Os dados foram analisados utilizando o programa STATISTICA 9.1, por meio dos Testes Quiquadrado e U de Mann-Whitney, Modelo de regressão linear simples e múltiplo. Resultados A permanência em UTI neonatal (65,52%), ototóxico (48,28%), ventilação mecânica (39,66%) e hiperbilirrubinemia (46,55%) foram os indicadores de risco mais frequentes na amostra. Considerando fatores socioeconômicos, demográficos e obstétricos, houve correlação entre pré-natal, idade gestacional, peso ao nascer e alimentação com o risco auditivo. A aquisição e desenvolvimento de linguagem mostrou significância estatística com a varicela, HIV, Apgar e peso >1500 gramas. Conclusão Os prematuros apresentaram maior frequência de indicadores de risco, comparados aos bebês a termo. Dos fatores ambientais, o pré-natal que interfere no desfecho da idade gestacional, peso ao nascer, apgar e presença de doenças infecciosas, além da alimentação, despontaram como significativos relacionados com o desenvolvimento da audição e a aquisição da linguagem. A prematuridade foi o fator biológico relevante relacionado ao risco auditivo e linguístico.


ABSTRACT Purpose To compare the frequency of risk indicators in preterm and full-term babies; to analyze the possible relationships among the presence of risk for hearing loss with language acquisition and socioeconomic, demographic and obstetric variables. Methods This is a longitudinal cohort study, with a sample of 87 babies. Gestational, obstetric and sociodemographic data were collected from mothers and babies. The socioeconomic classification status of the families were classified using the Brazilian Criteria for Economic Classification. The risk for language was assessed using the Language Acquisition Enunciation Signs and the Denver II test. The data were analyzed using the STATISTICA 9.1 software, using the chi-square and the Mann-Whitney U tests and simple and multiple linear regression models. Results Permanence in a neonatal intensive care (65.52%), ototoxic (48.28%), mechanical ventilation (39.66%) and hyperbilirubinemia (46.55%) were the more frequent risk indicators in the sample. Regarding socioeconomic, demographic and obstetric factors, there was a correlation among prenatal care, gestational age, birth weight, feeding with hearing risk. Acquisition and development of language showed statistical significance with varicella, HIV, Apgar score and birth weight >1500 grams. Conclusion Preterm babies showed higher frequency of risk indicators compared to full-term babies. Among environmental factors, prenatal care, which interferes in the outcome of gestational age, birth weight, Apgar score and presence of infectious diseases, as well as feeding, emerged as significant factors related to hearing and language acquisition. Prematurity was the relevant biological factor related to hearing and language risk.

ABSTRACT

Introdução: A associação entre perda auditiva e Diabetes Mellitus tipo 1 (DM1) é ainda pouco estudada. A perda auditiva é uma das complicações crônicas relacionadas ao grau de controle glicêmico, que os pacientes podem apresentar com a progressão da doença. Objetivo: Investigar o comprometimento auditivo por meio das emissões otoacústicas transitórias (EOAT) por banda de frequência em adolescentes com DM1 e relação com o controle glicêmico. Métodos: Foram incluídos 80 adolescentes, 50% do gênero masculino, entre 10 e 19 anos de idade: 40 com DM1 e 40 controles saudáveis, pareados por gênero e idade. Os dados clínicos e laboratoriais foram pesquisados nos prontuários médicos. O controle glicêmico foi avaliado por meio dos exames de hemoglobina glicada e os pacientes com DM1 analisados de acordo com o controle glicêmico. A avaliação auditiva foi realizada por meio da imitanciometria, audiometria, e posteriormente EOAT, em sala tratada acusticamente, pelo protocolo "TE Test" de clique não-linear (1 KHz a 4 kHz) a 80 dB NPS de intensidade (AuDX - Biologic). Resultados: As respostas às EOAT foram ausentes em 5,12% em pacientes com DM1, com diferença significativa em relação aos controles (p=0,04). A análise das EOAT por bandas de frequência mostrou maior proporção de alteração nos adolescentes com DM1 mal controlados quando comparados aos bem controlados, nas frequências de 1000Hz, 2000Hz e 3000Hz (p<0,05). Conclusão: As EOAT por bandas de frequência permitiram a identificação precoce de comprometimento auditivo em adolescentes com DM1 e mostraram associação entre DM1 mal controlado e perda auditiva.

Introduction: The association between hearing loss and type 1 diabetes mellitus (DM1) is still poorly studied. Hearing loss is one of the chronic complications related to the degree of glycemic control that patients may present with the progression of the disease. Objective: To investigate auditory impairment through transient otoacoustic emissions (TEOAE) by frequency band in adolescents with DM1 and in relation to glycemic control. Methods: Were included 80 adolescents, 50% males, between 10 and 19 years of age: 40 with DM1 and 40 healthy controls, matched by gender and age. Clinical and laboratory data were taken from the medical records. Glycemic control was evalueted by glycated hemoglobin and the patients with DM1 were analyzed according to glycemic control. To the auditory evaluation were used the immittance and audiometry, and the TEOAE. The test was performed in the acoustically treated room, the non-linear TE test protocol (1 KHz to 4 kHz) at 80 dB SPL (AuDX - Biologic ). Results: TEOAE responses were absent in 5.12% of patients with DM1, with a significant difference in relation to controls (p = 0.04). The analysis of TEOAE by frequency bands showed a higher proportion of alteration in adolescents with DM1 poorly controlled when compared to well controlled ones, in the frequencies of 1000Hz, 2000Hz and 3000Hz (p <0.05). Conclusion: TEOAE by frequency bands allowed the early identification of auditory impairment in adolescents with DM1 and showed an association between poorly controlled DM1 and hearing loss. (AU)

ABSTRACT

RESUMEN Introducción: La otoesclerosis representa la causa de hipoacusia de conducción más común en adultos jóvenes. Las opciones de tratamiento incluyen amplificación mediante audífonos o resolución quirúrgica a través de cirugías como estapedectomía total o parcial, estapedostomía o implante coclear. Objetivo: Describir los resultados del tratamiento quirúrgico de la otoesclerosis en el Departamento de Otorrinolaringología del Hospital Clínico de la Pontificia Universidad Católica de Chile entre los años 1999 y 2018. Material y método: Se realizó un estudio de cohorte no concurrente con revisión de fichas clínicas y protocolos operatorios de pacientes atendidos en nuestro centro. Se registraron y analizaron las características biodemográficas de los pacientes, técnicas quirúrgicas, resultados auditivos, complicaciones, necesidad de reintervención y uso de audífono. Resultados: De un total de 78 pacientes sometidos a estapedectomía parcial (platinectomía parcial) o estapedostomía se incluyeron finalmente 37 quienes tenían datos clínicos completos, lo que corresponde al 47,4% del total. En ambos tipos de cirugía el promedio de gap óseo-aéreo varió de 30,8 dB en el preoperatorio a 13,9 dB en el posoperatorio lo cual es estadísticamente significativo. El promedio de variación de la vía aérea, éste fue mayor en el grupo de pacientes operados de estapedostomía, sin existir diferencias estadísticamente significativas al realizar test no paramétricos. Conclusión: Las características demográficas y los resultados auditivos obtenidos en nuestro centro son comparables con los descritos en la literatura. No existen diferencias significativas en cuanto al tipo de cirugía y la frecuencia y tipo de complicaciones, aunque se observan mejores resultados auditivos en los pacientes operados de estapedostomía.


ABSTRACT Introduction: Otosclerosis represents the most common cause of hearing loss in young adults. Treatment options include amplification with hearing aids or surgical resolution with surgeries such as total and partial stapedectomy, stapedostomy or cochlear implant. Aim: To describe the results of the surgical treatment of otosclerosis in the Otorhinolaryngology Department of the Clinical Hospital of the Pontificia Universidad Católica de Chile between the years 1999 and 2018 Material and method: A non-concurrent cohort study was performed with review of clinical files and operative protocols of patients seen in our center. The biodemographic characteristics of the patients, surgical techniques, auditory results, complications, need for reoperation and use of hearing aid were recorded and analyzed. Results: Of a total of 78 patients undergoing partial stapedectomy or stapedostomy, 37 were finally included, who had complete clinical data, which corresponds to 47.4% of the total. In both types of surgery, the average bone-air gap varied from 30.8 dB in the preoperative to 13.9 dB in the postoperative period, which is statistically significant. Regarding the average of variation of the airway, this was higher in the group of patients operated by stapedostomy without statistically significant differences when performing nonparametric tests. Conclusion: The demographic characteristics and the auditory results obtained in our center are comparable with those described in the literature. There are no significant differences in the type of surgery and the frequency and type of complications, although better hearing results are observed in patients operated by stapedostomy.

ABSTRACT

Abstract Introduction: Hearing impairment is one of the communication disorders of the 21st century, constituting a public health issue as it affects communication, academic success, and life quality of students. Most cases of hearing loss before 15 years of age are avoidable, and early detection can help prevent academic delays and minimize other consequences. Objective: This study researched scientific literature for the prevalence of hearing impairment in school-aged children and adolescents, with its associated factors. This was accomplished by asking the defining question: "What is the prevalence of hearing impairment and its associated factors in school-aged children and adolescents?" Methods: Research included the databases PubMed/MEDLINE, LILACS, Web of Science, Scopus and SciELO, and was carried out by two researchers, independently. The selected papers were analyzed on the basis of the checklist provided by the report Strengthening the Reporting of Observational Studies in Epidemiology. Results: From the 463 papers analyzed, 26 fulfilled the criteria and were included in the review presented herein. The detection methods, as well as prevalence and associated factors, varied across studies. The prevalence reported by the studies varied between 0.88% and 46.70%. Otologic and non-otologic factors were associated with hearing impairment, such as middle ear and air passage infections, neo- and post-natal icterus, accumulation of cerumen, family history, suspicion of parents, use of earphones, age and income. Conclusion: There is heterogeneity regarding methodology, normality criteria, and prevalence and risk factors of studies about hearing loss in adolescents and school-aged children. Nevertheless, the relevance of the subject and the necessity of early interventions are unanimous across studies.


Resumo Introdução: A deficiência auditiva é um dos distúrbios de comunicação do século XXI, constitui um problema de saúde pública, pois afeta a comunicação, o sucesso acadêmico e a qualidade de vida dos estudantes. A maioria dos casos de perda auditiva antes dos 15 anos é evitável e a detecção precoce pode ajudar a evitar atrasos acadêmicos e minimizar outras consequências. Objetivo: Este estudo investigou a literatura científica sobre a prevalência da deficiência auditiva em crianças e adolescentes em idade escolar, com seus fatores associados. Isso foi feito através da questão norteadora: "Qual a prevalência da deficiência auditiva e seus fatores associados em crianças e adolescentes em idade escolar?" Método: A pesquisa compreendeu as bases de dados PubMed/MEDLINE, LILACS, Web of Science, Scopus e SciELO e foi feita de forma independente por dois pesquisadores. Os artigos selecionados foram analisados com base na lista de verificação fornecida pelo relatório Strengthening the Reporting of Observational Studies in Epidemiology. Resultados: Dos 463 artigos analisados, 26 preencheram os critérios e foram incluídos na revisão aqui apresentada. Os métodos de detecção, assim como a prevalência e os fatores associados, variaram entre os estudos. A prevalência relatada pelos estudos variou entre 0,88% e 46,70%. Fatores otológicos e não otológicos foram associados à deficiência auditiva, como infecções da orelha média e das vias aéreas, icterícia neonatal e pós-natal, acúmulo de cerúmen, histórico familiar, suspeita dos pais, uso de fones de ouvido, idade e renda. Conclusão: Há heterogeneidade quanto à metodologia, aos critérios de normalidade e, consequentemente, à prevalência e aos fatores associados nos estudos sobre da perda auditiva em adolescentes e crianças em idade escolar. No entanto, a relevância do assunto e a necessidade de intervenções precoces são unânimes entre os estudos.

ABSTRACT

Abstract Introduction: Intralabyrinthine schwannoma is a rare, benign tumor that affects the most terminal portions of the vestibular and cochlear nerves. This tumor can be classified into 10 subtypes, according to its inner ear location. Objective: To carry out a comprehensive review of the most frequent auditory manifestations secondary to the intralabyrinthine schwannoma, describing the possible underlying pathophysiological mechanisms. Methods: Systematic review of the literature until October 2017 using the PubMed, Web of Science and Scopus databases. The inclusion criteria were clinical manifestations of the intralabyrinthine schwannoma. Three researchers independently assessed the articles and extracted relevant information. The description of a case of an intravestibular subtype intralabyrinthine schwannoma with multiple forms of clinical presentations was used as an example. Results: Twenty-seven studies met our inclusion criteria. The most common intralabyrinthine schwannoma subtype was the intracochlear, followed by the intravestibular type. All the cases demonstrated hearing loss, usually progressive hearing loss. Conclusion: The diagnosis of intralabyrinthine schwannomas is based on high-resolution magnetic resonance imaging and should be included in the differential diagnosis of patients with vestibulocochlear complaints. Although there are approximately 600 cases in the literature, we still lack a detailed description of the clinical evolution of the patients, correlating it with MRI findings of temporal bones and tumor subtype.


Resumo Introdução: Schwannoma intralabiríntico é um tumor benigno, raro, que afeta as porções mais terminais dos nervos vestibular e coclear. Este tumor pode ser classificado, de acordo com sua localização na orelha interna, em 10 subtipos. Objetivo: Realizar uma revisão abrangente das manifestações auditivas mais frequentes secundárias ao schwannoma intralabiríntico e descrever os possíveis mecanismos fisiopatológicos subjacentes. Método: Revisão sistemática da literatura até outubro de 2017 nas bases de dados PubMed, Web of Science e Scopus. O critério de inclusão foi manifestações clínicas do schwannoma intralabiríntico. Três pesquisadores avaliaram de forma independente os artigos e extraíram informações relevantes. Exemplificamos com a descrição de um caso de schwannoma intralabiríntico subtipo intravestibular com múltiplas formas de apresentações clínicas. Resultados: Vinte sete estudos contemplaram nossos critérios de inclusão. O subtipo do schwannoma intralabiríntico mais comum encontrado foi o intracoclear, seguido pelo intravestibular. Todos os casos apresentaram alteração auditiva, normalmente perda auditiva progressiva. Conclusão: O diagnóstico de schwannomas intralabirínticos baseia-se em exames de ressonância magnética de alta resolução e deve ser incluído no diagnóstico diferencial de pacientes com queixas vestibulococleares. Apesar de termos aproximadamente 600 casos na literatura, ainda nos falta descrição detalhada da evolução clínica dos pacientes em correlação com achados na ressonância magnética de ossos temporais e o subtipo tumoral.

ABSTRACT

INTRODUCCIÓN La enfermedad de Ménière es una anomalía del oído interno caracterizada por episodios de vértigo espontáneo, hipoacusia fluctuante y tinnitus. La terapia con presión positiva ha sido utilizada para reducir la intensidad y la frecuencia de las crisis, pero existe controversia respecto a su eficacia. MÉTODOS Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES Identificamos cinco revisiones sistemáticas que en conjunto incluyeron 22 estudios primarios, de los cuales cinco corresponden a ensayos aleatorizados. Concluimos que la terapia de presión positiva probablemente empeora levemente la audición y no reduce la intensidad del vértigo. Además, no es posible establecer con claridad si la terapia de presión positiva mejora la funcionalidad o si disminuye la frecuencia de los ataques de vértigo, porque la certeza de la evidencia existente ha sido evaluada como muy baja.


INTRODUCTION Ménière's disease is a disorder of the inner ear characterized by episodes of spontaneous vertigo, fluctuating hearing loss and tinnitus. Positive pressure therapy has been used to reduce the intensity and frequency of episodes, but it is not clear whether it is actually effective. METHODS We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified five systematic reviews including 22 studies overall, of which five were randomized trials. We concluded positive pressure therapy probably leads to slightly worse hearing and makes little or no difference in the intensity of vertigo. In addition, we are uncertain whether positive pressure therapy improves functionality or decreases vertigo attacks as the certainty of the evidence has been assessed as very low.

ABSTRACT

Resumen Introducción: Desde la década de los 90, los implantes cocleares han progresado desde aplicaciones experimentales a un uso clínico estandarizado en niños con pérdida auditiva severa y profunda. Las investigaciones han producido cambios en la tecnología de los implantes y ha dado lugar a la expansión de los candidatos a implante para incluir a los niños menores de 2 años de edad. El objetivo principal de la implantación coclear pediátrica es facilitar el desarrollo del lenguaje hablado. A pesar de los avances en la tecnología de implantes y los cambios en el manejo de la pérdida auditiva, los resultados de lenguaje en niños son todavía muy variables, participando de este proceso tanto el tratamiento oportuno, la red familiar y nivel socioeconómico entre algunos de ellos. Objetivo: Describir resultados de niños menores 6 años sometidos a cirugía de implante coclear en un centro terciario de salud. Material y método: Estudio longitudinal de cohorte retrospectivo, análisis a 99 pacientes implantados en centro terciario de salud desde inicio programa en 1994 a 2015. Resultados: 99 pacientes, 57% hombres 43% mujeres, edad promedio implantación 16,3 meses. 54,8% casos origen congénito no especificado o prematurez. En 74,4% se objetivó presencia de lenguaje auditivo verbal. El nivel socioeconómico (NSE) mostró asociación con no desarrollo de lenguaje (p =0,009) evidenciando que pacientes de bajo NSE 20% no desarrolla lenguaje. La variable discapacidad asociada (p <0,001) y la variable NSE (p =0,036) se asociaron de manera independiente a lenguaje de señas o no desarrollo de lenguaje oral. Conclusión: Los implantes cocleares ofrecen una opción en la rehabilitación auditiva en hipoacusia sensorio neural profunda, para candidatos de todo el espectro de edad, sin embargo los resultados dependen en gran medida del entorno en el que se utilizan los implantes cocleares.


ABSTRACT Introduction: Since the 90s, cochlear implantation has progressed from experimental to standard clinical practice for children with severe and profound hearing loss. Research has produced changes in implant technology and has led to the expansion of implant candidacy to include children younger than 2 years of age. The primary goal of pediatric cochlear implantation is to facilitate spoken language development. Despite the advances in implant technology and the changes to the management of hearing loss, language outcomes for children are still highly variable, participating in this process both timely treatment, the family network and socio economic level among others. Aim: describe outcomes of patients younger than 6 years undergoing cochlear implant surgery in a tertiary care center. Material and method: retrospective longitudinal cohort study, 99 patients implanted in a tertiary health center since the program's inception in 1994 to 2015 was analyzed. Results: 99 patients, 57 % men 43 % women, average age of implantation 16.3 months. 54.8 % of cases were congenital or prematurity. In 74.4 % they had auditory verbal language. Socioeconomic status (SES) showed association with the lack of language development (p =0.009) demonstrating that low SES patients (20%) do not develop language. The disability associated variable (p <0.001) and the SES variable (p =0.036) were independently associated with sign language or no oral language development. Conclusions: Cochlear implants offer an option for hearing rehabilitation in profound hearing loss, for candidates of all ages, however the results depend largely on the environment in which cochlear implants are used.

ABSTRACT

Abstract Introduction Numerous studies have evaluated auditory functions in human immunodeficiency virus (HIV) patients; however, these studies had a few major limitations in terms of methodology as they used mainly evoked audiometry although this method is expensive, time consuming and not widely available. Therefore, we conducted a study in naïve HIV subjects with routine audiometry. Objective To determine the effect of HIV and of the drugs used to treat it on the auditory functions. Methods A prospective observational study was conducted in a medical college with 25 naive HIV-seropositive patients for over a year. Pure tone audiometry (250-8,000 Hz) and CD4 T-lymphocyte count were performed at the time of enrollment and 6 months after commencement of highly active antiretroviral treatment. Results The subjects had increased hearing thresholds at high frequencies (4 KHz and 8KHz) in both ears at the time of enrollment that persisted at the same level (p > 0.05) on follow-up at 6 months. None of the subjects had any other otological symptom during the 6 months of observation. Seven subjects had sensorineural hearing loss in one or both ears at 0 and 6 months. These observations did not show any significant difference on Wilcoxon-signed-rank test. Spearman correlation did not find a significant correlation (p > 0.05) between CD4 T-lymphocyte counts and pure tone audiometry during the study. Conclusion We found high-frequency hearing loss in all subjects with no relation with highly active antiretroviral therapy (HAART) and severity of the disease. This study advocates hearing assessment with pure tone audiometry in HIV subjects so that intervention can be initiated in a timely manner.

ABSTRACT

Abstract Introduction: Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. Objective: To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. Methods: 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. Results: When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4 kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2 kHz, 3 kHz and 8 kHz. Conclusion: It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions, hypertension seems to have the greatest influence on hearing.


Resumo: Introdução: Doenças crônicas podem atuar como fator de aceleração na degeneração do sistema auditivo. Os estudos sobre a associação da presbiacusia com o diabetes mellitus e com a hipertensão arterial sistêmica mostraram conclusões controversas. Objetivo: Comparar a audiometria inicial (A1) com uma audiometria sequencial (A2) feita com um intervalo de três a quatro anos em uma população de idosos portadores de diabetes mellitus e/ou hipertensão arterial sistêmica, a fim de saber se a perda de acuidade auditiva nesses grupos é mais acelerada comparados com controles sem essas condições clínicas. Método: Participaram deste estudo 100 idosos. Para a análise dos limiares auditivos, foram usadas: uma avaliação audiológica completa feita anteriormente (A1) e uma nova avaliação audiológica (A2) feita após três a quatro anos da primeira. Os participantes foram distribuídos em quatro grupos: 20 indivíduos no grupo com diabetes mellitus, 20 no grupo hipertensão arterial sistêmica, 20 no grupo diabetes mellitus/hipertensão arterial sistêmica e 40 indivíduos no grupo controle, foram pareados com cada grupo de estudo, de acordo com as características referentes a idade e sexo. Foram usados os testes estatísticos Anova e Kruskal-Wallis, com nível de significância de 0,05. Resultados: Na comparação da média de aumento anual dos limiares auditivos da avaliação A1 com a avaliação A2, considerando cada grupo estudo e seu respectivo controle, pode-se observar que para o grupo diabetes mellitus não houve diferença estatisticamente significante para qualquer das frequências; para o grupo hipertensão arterial sistêmica foram observadas diferenças significantes a partir de 4 kHz. Já para o grupo diabetes mellitus/hipertensão arterial sistêmica foram observadas diferenças significantes nas frequências de 500, 2k, 3k e 8 kHz. Conclusão: Verificou-se que o grupo hipertensão arterial sistêmica foi o que apresentou maior queda dos limiares auditivos no segmento estudado, quando comparado com os outros grupos, sugeriu que entre as três condições estudadas a hipertensão parece ser a que teve maior influência sobre a audição.

ABSTRACT

Abstract Introduction Acromegaly is a chronic disease caused by growth hormone (GH) excess due to a GH-secreting pituitary adenoma in most cases. There is reasonable data to presume the possible influence of chronic GH and insulin-like growth factor I (IGF-I) hyperproduction on the anatomical structures involved in normal sound perception, and on its conductive and/or sensorineural part. Objectives To review the literature about acromegaly and hearing loss. Data Synthesis A systematic literature search was performed using the MEDLINE database, including hand-searching reference lists from original articles. The search was performed using the terms hearing loss and acromegaly, and only 5 studies were found. Conclusion The results are not consistent, but led to different conclusions. Therefore, more studies with greater numbers of patients with acromegaly are needed.

ABSTRACT

RESUMEN El síndrome de Susac (SS) es una enfermedad autoinmune microangiopática poco frecuente, caracterizada por la tríada clínica: encefalopatía, alteraciones visuales e hipoacusia. Es una entidad de prevalencia desconocida dado su difícil diagnóstico debido a que la mayoría de las veces no se presenta con la tríada clínica clásica, y, dado que presenta múltiples diagnósticos diferenciales. Se reporta un caso de SS presentado en el Hospital del Salvador, con descripción de sus manifestaciones clínicas, estudio y manejo inicial. Además de una revisión en la literatura sobre la variabilidad de los hallazgos clínicos y el manejo de esta patología.


ABSTRACT Susac syndrome (SS) is a rare autoimmune micronagiopathic disease, characterized by the clinical triad of, encephalopathy, visual impairment and hearing loss. It is a difficult entity to diagnose since most of the time it does not present itself with the classical clinical triad, and it may be confused with other differential diagnoses. One clinical case of a patient with SS is described, its clinical manifestations, diagnosis and initial treatment. In addition, a literature review about the multiple clinical findings and management of these disease.

ABSTRACT

OBJECTIVES: To characterize the audiometric evaluation and acoustic immittance measures in different types of mucopolysaccharidosis. METHOD: Fifty-three mucopolysaccharidosis patients were evaluated. The classification consisted of type I (Hurler syndrome, Hurler-Scheie and Scheie syndrome), type II (Hunter syndrome), type III (Sanfilippo syndrome), type IV (Morquio syndrome), and type VI (Maroteaux-Lamy syndrome). Immittance audiometry and play or conventional threshold tone audiometry were used to obtain auditory thresholds and were chosen according to the patient's chronological age and ability to understand/respond to the procedure. The findings were analyzed using descriptive statistics and considering the recommendations for research involving human beings contained in Resolution CNE N° 466/2012. RESULTS: Fifty-one subjects (96.2%) had hearing loss, and the conductive type was the most frequent. Only two (3.8%) patients presented bilateral thresholds within normal limits, one with type IV mucopolysaccharidosis and the other with type VI. There were 11 individuals (20.8%) with mucopolysaccharidosis type I with mixed hearing loss, 9 (16.9%) individuals with type I with conductive hearing loss and 9 (16.9%) with type VI with conductive hearing loss. Mild hearing loss was most common (37.3%), followed by moderately severe hearing loss (36.3%). The type B tympanometric curve (80.4%) was the most frequent. CONCLUSIONS: Most of the individuals with mucopolysaccharidosis types I, II, III, IV and VI presented mixed or conductive hearing losses of mild to moderately severe degree, type B tympanograms and an absence of contralateral acoustic reflexes.

ABSTRACT

INTRODUCCIÓN: La enfermedad de Ménière es una anomalía del oído interno caracterizada por episodios de vértigo espontáneo, hipoacusia fluctuante y tinnitus. Los diuréticos han sido ampliamente utilizados para el tratamiento de las crisis de esta enfermedad, pero existe controversia respecto a su eficacia. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos tres revisiones sistemáticas que en conjunto incluyen diecinueve estudios primarios, de los cuales, cuatro son ensayos aleatorizados. Concluimos que no está claro si el uso de diuréticos lleva a una mejoría sintomática del vértigo o a una disminución objetiva de la hipoacusia en pacientes con enfermedad de Ménière, porque la certeza de la evidencia es muy baja.


INTRODUCTION: Ménière`s disease is an inner ear disorder characterized by episodes of spontaneous vertigo, fluctuating hearing loss and tinnitus. Diuretics have been widely used for the treatment of attacks, but there is controversy about their effectiveness. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified three systematic reviews including nineteen studies overall, of which four were randomized trials. We concluded it is not clear whether diuretics lead to a symptomatic improvement of vertigo or an objective decrease in hearing loss in patients with Ménière`s disease, because the certainty of the evidence is very low.
