Percepção de familiares e autopercepção de idosos usuários de dispositivos de amplificação quanto à restrição de participação causada pela deficiência auditiva / Perception of family members and self -perception of the elderly users of amplification devices regarding the restriction of participation caused by hearing impairment / Percepción de los miembros de la familia y la autopercepción de los ancianos usuarios de dispositivos de amplificación sobre la restricción de la participación causada por la discapacidad auditiva

Introdução: A deficiência auditiva tem um efeito profundo na vida dos idosos. O apoio dos familiares no processo de reabilitação cria meios para facilitar a aceitação da deficiência e o uso dos dispositivos auditivos. Objetivo: Analisar a percepção dos familiares quanto à restrição da participação causada pela deficiência auditiva em indivíduos idosos usuários de aparelho de amplificação sonora individual (AASI) e compará-la com a autopercepção do próprio idoso quando a este aspecto. Métodos: A amostra foi composta por 48 indivíduos, que foram divididos em dois grupos, sendo GI o grupo de idosos, composto por 24 idosos com perda auditiva sensorioneural bilateral usuários de AASI; e GF o grupo de familiares, composto por 24 familiares, que acompanhavam esses idosos. Os participantes do GI responderam ao questionário de autoavaliação Hearing Handicap Inventory for the Elderly (HHIE) e os participantes do GF responderam ao questionário Hearing Handicap Inventory for the Elderly for Spouses (HHIE-SP). Resultados: Não houve correlação entre o tempo de uso do AASI e o escore obtido no questionário. Observou-se que, quanto maior a idade do idoso, piores foram os resultados encontrados no domínio "emocional" do HHIE para o grupo GI e para os domínios "social" e "emocional" para o grupo GF. Além disso, houve correlação entre os dois grupos, indicando que, quanto piores os resultados no HHIE para o GI, também foram piores os resultados no HHIE-SP respondido pelo GF. Conclusão: Arestrição de participação social e os aspectos emocionais influenciados pela perda auditiva em indivíduos idosos usuários de AASI são fatores percebidos pelos familiares que os acompanham nas consultas fonoaudiológicas.

Introduction: Hearing loss has a profound effect on the lives of the elderly. The support of family members in the rehabilitation process creates ways to facilitate the acceptance of the disability and the use of hearing devices. Objective: To analyze the perception of family members regarding the restriction of participation caused by hearing impairment in elderly individuals users of hearing aids and compare it with the self-perception of the elderly in this regard. Methods: The sample consisted of 48 individuals, who were divided into two groups, EG being the elderly group, composed of 24 elderly people with bilateral sensorineural hearing loss, who use HA; and FG the group of family members, composed of 24 family members, who accompanied these elderly people. EG participants answered the Hearing Handicap Inventory for the Elderly (HHIE) self-assessment questionnaire and FG participants answered the Hearing Handicap Inventory for the Elderly for Spouses (HHIE-SP). Results: There was no correlation between the time of HA use and the score obtained in the questionnaire. It was observed that the older the person, the worse the results found in the "emotional" domain of the HHIE for the EG group, and the "social" and "emotional" domains for the FG group. In addition, there was a correlation between the two groups, indicating that the worse the results in the HHIE for the EG, the worse the results in the HHIE-SP answered by the GF. Conclusion: The restriction of social participation and the emotional aspects influenced by hearing loss in the elderly who use HA are factors perceived by family members who accompany them in audiology appointments.

Conclusión: La restricción de la participación social y los aspectos emocionales influenciados por la hipoacusia en adultos mayores usuarios de audífonos son factores percibidos por los familiares que los acompañan en las consultas de audiología.(AU)

Beethoven´s illnesses and a craniovertebral junction variant? / As doenças de Beethoven e variante da junção craniovertebral?

Ludwig van Beethoven, the great composer, born 250 years ago, had several health problems and a progressive hearing loss. Gastrointestinal symptoms prevailed among his physical complaints, but there were also frequent headaches, eye pain, and polyarthralgia. Likewise, there are many reports about his alcohol intake and frequent walks. There were also peculiar behavioral and awkward physical aspects of the famous composer. All may take part as a determinant for the communicative aspects of his music. Spite Beethoven's corporal structure could be considered just a developmental variant, it can also be congenitally related to many bone-nervous abnormalities such as craniovertebral junction malformation with interference in the Genius' health. In reality, it is almost impossible to cover Beethoven's entire health problem with just one underlying disease. Most likely, he had comorbidities, one of which, although not fatal, was that related to abnormalities in the development of the skull and cervical spine worsened by a baseline autoimmune disorders that injured joints, and maybe even the VIII cranial nerve and inner ear.

Ludwig van Beethoven, o grande compositor, nascido há 250 anos, teve vários problemas de saúde e uma perda auditiva progressiva. Os sintomas gastrointestinais prevaleceram entre suas queixas físicas, mas também houve frequentes episódios de cefaleia, dores nos olhos e poliartralgia. Da mesma forma, há muitos relatos sobre sua ingestão de álcool e caminhadas frequentes. Havia também aspectos físicos peculiares e estranhos do famoso compositor. Todos podem tomar parte como um determinante para os aspectos comunicativos de sua música. Apesar da estrutura corporal de Beethoven poder ser considerada apenas uma variante de desenvolvimento, pode também estar relacionada a algumas anormalidades ósseo- neural, tais como a malformação da junção craniovertebral com interferência na saúde do Gênio. Na realidade, é quase impossível cobrir todo o problema de saúde de Beethoven com apenas uma doença subjacente. Muito provavelmente, ele tinha comorbidades, uma das quais, embora não fatal, era aquela relacionada a anormalidades no desenvolvimento do crânio e da coluna cervical agravadas por uma desordem auto-imune de base que lesionava as articulações, e talvez até o VIII nervo craniano e o ouvido interno.

Hyperbilirubinemia impact on newborn hearing: a literature review

SUMMARY The increase in bilirubin levels in newborns can cause toxic effects on the auditory system, which can lead to hearing loss. This review aimed to verify the impact of hyperbilirubinemia in the hearing of newborns, relating audiological findings to serum levels of bilirubin. A literature review was conducted during October 2017, using the terms "hyperbilirubinemia", "jaundice", "infant", "newborn" and "hearing loss", on databases CAPES journals, MEDLINE and BIREME (SciELO, BBO). 827 studies were identified and 59 were selected for full-text reading, resulting in the selection of seven articles that met the inclusion criteria and were considered relevant to the sample of this study. All the reviewed studies performed brainstem auditory evoked potential as the main test for audiological evaluation. Changes in the audiological findings of neonates with hyperbilirubinemia were observed in all studies. There was no consensus on the serum bilirubin levels that may cause auditory changes; however, the relationship between hearing disorders and blood levels of bilirubin was positive. We identify the need to establish reference values for bilirubin levels considered critical for the occurrence of hearing disorders as well as the audiological follow-up of neonates with hyperbilirubinemia.

RESUMO O aumento nos níveis de bilirrubina no neonato pode provocar efeitos tóxicos no sistema auditivo, podendo levar à perda auditiva. O objetivo desta revisão foi verificar o impacto da hiperbilirrubinemia na audição de recém-nascidos, relacionando os achados audiológicos aos níveis séricos de bilirrubina. Realizou-se uma revisão sistemática de literatura durante o mês de outubro de 2017, utilizando-se os termos hyperbilirubinemia, jaundice, infant, newborn e hearing loss, nas bases de dados periódicos Capes, Medline e Bireme (SciELO, BBO). Foram identificados 827 estudos, dentre os quais 59 foram selecionados para leitura do texto na íntegra, resultando na seleção de sete artigos que atendiam aos critérios de inclusão e foram considerados relevantes para a amostra deste trabalho. Em todas as pesquisas revisadas, o potencial evocado auditivo de tronco encefálico foi o principal exame audiológico realizado. Em todos os estudos foram observadas alterações nos resultados audiológicos de neonatos com hiperbilirrubinemia. Não houve consenso quanto aos níveis séricos de bilirrubina que podem causar alterações auditivas, porém, a relação entre as alterações audiológicas e os níveis sanguíneos de bilirrubina foi positiva. Percebeu-se a necessidade de estabelecer valores de referência para os níveis de bilirrubina considerados críticos para a ocorrência de alterações audiológicas, assim como de acompanhamento audiológico dos neonatos com hiperbilirrubinemia.

Autopercepção do zumbido: estudo pré e pós-adaptação de próteses auditivas / Self-perception of tinnitus: study before and after adaptation of hearing aids

RESUMO Objetivo Verificar benefícios do uso de próteses auditivas na autopercepção do zumbido em adultos e idosos sem experiência prévia de amplificação. Métodos O estudo incluiu indivíduos de ambos os sexos, com queixa de zumbido, acompanhados em hospital público. Aplicaram-se os seguintes exames e instrumentos para mensurar o zumbido e determinar o seu incômodo: pesquisa do pitch e loudness, Escala Visual Analógica (EVA), pesquisa do nível mínimo de mascaramento, inibição residual e Tinnitus Handicap Inventory (THI). As avaliações foram realizadas em duas etapas: antes da adaptação das próteses auditivas e após um mês de uso dos aparelhos. Resultados Dos 20 indivíduos participantes, 60% eram idosos. Verificou-se diferença na autopercepção do zumbido pré e pós-protetização, medido pelas escalas THI e EVA. Também se observaram diferenças nas medidas psicoacústicas, com exceção do pitch, antes e após a amplificação. Além disso, houve correlação entre o tempo de zumbido e a idade com os escores finais do THI. Conclusão O uso de próteses auditivas reduziu o incômodo provocado pelo zumbido, com alteração nas medidas psicoaústicas e no impacto na qualidade de vida.

ABSTRACT Purpose To verify the benefits of using hearing aids in self-perception of tinnitus in adults and elderly without previous experience of amplification. Methods The study included individuals of both gender, with tinnitus complaint, accompanied in public hospital. The following tests and instruments were used to measure tinnitus and determine its discomfort: pitch and loudness, Visual Analogue Scale (VAS), minimum masking level, residual inhibition and Tinnitus Handicap Inventory (THI). The evaluations were performed in two stages: before the adaptation of the hearing aids and after one month of use of the devices. Results Of the 20 participants, 60% were elderly. There was a difference in self-perception of tinnitus before and after hearing aid fitting, as measured by THI and VAS. Differences in psychoacoustic measures were also observed, with the exception of pitch, before and after amplification. In addition, there was a correlation between tinnitus time and age with final THI scores. Conclusion The use of hearing aids was determined to reduce the annoyance caused by tinnitus, with changes in psycho-acoustic measures and impact on quality of life.

Self-reported hearing loss and visual impairment in adults from Central Mexico / Autorreporte de pérdida auditiva y discapacidad visual en adultos del centro de México

Abstract: Objective: To determinate the prevalence of hearing loss (HL) and visual impairment (VI) among adult population from Tlaxcala, Mexico. Materials and methods: A population-based cross-sectional study comprising persons 50 years and older was conducted in 2013. Self-reported HL was measured using the Hearing Impairment Inventory for the Elderly (SHIIE) questionnaire; VI was determined using the Snellen tumbling E chart. Results: 900 women and 611 men (mean age 66.1 years) were included. 481(31.8%) individuals had HL (415 alone and 66 combined with VI). Prevalence of HL alone and together with VI was associated with age (per two years, OR=1.03 and OR=1.18, respectively) and self-reported poor health status (OR=1.90 and OR=3.69, respectively). Conclusion: The high prevalence of these disabilities calls for the implementation of public health interventions that help to reduce its impact in the population.

Resumen: Objetivo: Determinar la prevalencia de discapacidad auditiva (DA) y visual (DV) en adultos del estado de Tlaxcala, México. Material y métodos: Estudio transversal de base poblacional realizado en 2013 que incluye sujetos ≥50 años de edad. La DA se evaluó por autorreporte con el cuestionario Hearing Impairment Inventory for the Elderly (SHIIE); la DV se midió usando la cartilla E rotatoria de Snellen. Resultados: Se evaluaron 900 mujeres y 611 hombres (media=66.1 años). El 31.8% (481) tenía DA (415 sola y 66 con DV). La prevalencia de DA sola o con DV se asoció con edad (por cada dos años, RM=1.03 y RM=1.18, respectivamente) y con autorreporte del estado de salud deficiente (RM=1.90 y RM=3.69, respectivamente). Conclusiones: Se requiere la implementación de intervenciones en salud pública que reduzcan el impacto de estas dos condiciones en la población.

Los problemas auditivos aumentan el riesgo de deterioro cognitivo en adultos mayores chilenos / Hearing impairments increase the risk of cognitive impairment in older Chilean adults

RESUMEN Introducción: Estudios previos han asociado la pérdida auditiva con un acelerado deterioro cognitivo durante el envejecimiento; no obstante, esta asociación no ha sido estudiada en adultos mayores chilenos. Objetivo: Investigar la asociación entre la discapacidad auditiva y la sospecha de deterioro cognitivo a través del cuestionario Mini Mental State Examination (MMSE, versión abreviada) en esta población. Material y método: Se incluyeron 1.384 adultos mayores de 60 años de la encuesta nacional de salud 2009-2010. Un puntaje <13 puntos en el MMSE se consideró sospecha de deterioro cognitivo. La discapacidad auditiva se determinó a través de un cuestionario de tamizaje autorreportado de tres preguntas. La asociación entre estas dos variables se investigó mediante análisis de regresión logística. Resultados: Se identificó una asociación significativa entre el MMSE alterado y cada una de las discapacidades auditivas estudiadas. A su vez, existió una tendencia a aumentar en 59% la probabilidad de desarrollar deterioro cognitivo en la medida que aumentaron las discapacidades auditivas (OR: 1,59 [95% IC: 1,38 a 1,82], p <0,0001). Conclusión: La disminución de la percepción auditiva es un factor de riesgo para el desarrollo de deterioro cognitivo y posteriormente demencia. La creación de políticas públicas, orientadas al tamizaje temprano en población de riesgo, podría ser una solución efectiva para prevenir las consecuencias asociadas con esta condición.

ABSTRACT Introduction: Hearing loss has been associated with an accelerated cognitive impairment during ageing. However, this association has not been investigated in older Chilean adults. Aim: To investigate the association between hearing impairment and cognitive impairment, using the Mini-Mental State Examination (MMSE, abridged version), in the Chilean population. Material and methods: 1,384 older adults aged ≥60 years, from 2009-2010 Chilean national health survey, were included. <13 points in the MMSE were considered suspicion of cognitive impairment. Hearing impairment was determined through a questionnaire including 3 domains. The association between cognitive and hearing loss was investigated using logistic regression. Results: An association between MMSE and each hearing disabilities studied was identified. As hearing impairments increased, the odd for cognitive impairment incremented by 59% (OR: 1.59 [95% IC: 1.38 a 1.82], p <0.0001). Conclusion: Hearing loss is a risk factor to develop cognitive impairment, which could translate into a high risk of dementia. Public politics implementation, focused in an early screening, could be an effective approach to prevent the complications associated with this hearing loss in older adults.

Perfil clínico e implicações do zumbido em indivíduos com e sem perda auditiva / Clinical profile and implications of tinnitus in individuals with and without hearing loss

RESUMO Objetivo comparar as características clínicas do zumbido e interferência na qualidade de vida em indivíduos com e sem perda auditiva associada, bem como discutir a associação de mensurações quantitativas e instrumentos qualitativos de avaliação. Método estudo quantitativo, descritivo e de corte transversal aprovado pelo Comitê de Ética em pesquisa (nº 973.314/2016 CAEE: 41634815.3.0000.0106). Foram comparadas as respostas da avaliação psicoacústica do zumbido (pesquisa de intensidade, frequência, nível mínimo de mascaramento e limiar de desconforto para tom puro e fala), bem como questionário Tinnitus Handicap Inventory (THI) e escala visual analógica (EVA) de 15 sujeitos portadores de zumbido e perda auditiva periférica (grupo GI) e 16 indivíduos normo-ouvintes (grupo GII). Resultados O escore médio na EVA e THI no GI foi, respectivamente, de 5,1(+1,5) e 42,3(+18) e no GII de 5,7(+2.6) e 32,7(+25), sugerindo incômodo moderado no GI e moderado/leve no GII (p>0,005). Verificou-se correlação moderada entre o THI e EVA apenas no GII. Na avaliação psicoacústica, observaram-se diferenças significantes entre os grupos referentes à medida da loudness (*p=0,013) e ao nível mínimo de mascaramento (*p=0,001). Conclusão a perda auditiva parece não se constituir em um fator determinante para o maior ou menor impacto do zumbido na qualidade de vida do sujeito. Já as diferenças encontradas entre os grupos, referentes às medidas psicoacústicas, podem ser justificadas pela presença do dano coclear em si. A mensuração objetiva do zumbido, independentemente da presença ou não da perda auditiva periférica, caracteriza-se como um importante instrumento complementar às medidas de auto avaliação.

ABSTRACT Purpose To compare clinical characteristics of tinnitus and interference in quality of life in individuals with and without associated hearing loss, as well as to discuss the association of quantitative measurements and qualitative instruments. Methods A quantitative, cross-sectional and comparative study approved by the Research Ethics Committee (No. 973.314/CAEE: 41634815.3.0000.0106) was carried out. The responses of the psychoacoustic assessment of tinnitus (intensity, frequency, minimum masking level and loudness discomfort level for pure tone and speech), as well as the Tinnitus Handicap Inventory (THI) questionnaire, and the visual analogue scale (VAS) were compared between 15 patients with tinnitus and peripheral hearing loss (group I) and 16 adults with normal hearing (group II). Results The mean VAS and THI scores obtained in GI were 5.1 (+1.5) and 42.3 (+18), and in GII, 5.7 (+2.6) and 32.7 (+25), respectively. This result suggests moderate GI annoyance and moderate/mild GII annoyance (p>0.005). There was a positive and moderate correlation between THI and VAS only in GII. In the psychoacoustic evaluation, significant differences were observed between the groups regarding the measurement of loudness (*p=0.013) and the minimum masking level (*p=0.001). Conclusion There was no direct influence of the presence of hearing loss in relation to the impact of tinnitus. The differences found between the groups regarding the psychoacoustics measures can be justified by the presence of cochlear damage. The objective measurement of tinnitus, regardless of the presence or absence of peripheral hearing loss, is an important instrument to be used along with self-evaluation measures.

A review on medicinal plants used for treating ototoxicity and acoustic trauma induced hearing loss

Hearing loss induced by chemotherapy and acoustic trauma is mainly associated with two factors, free radical formation and apoptosis pathway activation. Despite numerous efforts on reducing the effects of these factors, no definite strategy is still determined to interfere with and control these processes. In recent studies, various protective agents, including antioxidants have been used on animal models, to inhibit the formation of free radicals thus improving hearing loss.In this review article we will discuss the role of traditional herbal medicine in treatment of noise/drug induced hearing loss, focusing on medicinal plants' active substances,as well as their mechanisms of action in reducing or preventing the formation of free radicals thus increasing the rate of survival of cochlea cells. Data have been gathered since year 2000, from scientific publications including the following keywords: deafness, drug toxicity, acute trauma, medicinal herbs and oxidative stress. The study includes all herbs and medicinal plants that have been experimentally used in studies on animal models and clinical trials. The results from these studies indicate the effectiveness of most of these herbs and their active substances through their antioxidative properties. Medicinal plants reported in this review can thus be considered as effective remedies intreating noise/drug induced hearing loss,yet further studies need to be done.

Probable Association of Hearing Loss, Hypertension and Diabetes Mellitus in the Elderly

Abstract Introduction The aging process causes changes in body structure in a continuous manner, and contributes to clinical disorders. Life expectancy is increasing, especially in developing countries. Objective To assess the prevalence of hearing loss and its possible association with hypertension and diabetes mellitus (DM) in the elderly. Methods A cross-sectional study with 519 elderly individuals aged over 60 years who underwent an audiological evaluation (pure tone audiometry), and answered a comorbidity questionnaire that included questions about age, gender, tinnitus and medical history, with data concerning DM. The dependent variable was the presence of hearing loss. The independent variables were age, gender, DM and hypertension. The variables were presented in absolute numbers and proportions, and enabled us to estimate the prevalence. The statistical analysis was performed through multiple logistic regression with 95% confidence intervals and values of p< 0.05 for the hearing loss and its associated factors. Results A total of 519 subjects of both genders with a median age of 69 years were evaluated, and the individuals who did not attend the audiometric test were excluded from the study, so the final sample was composed of 498 subjects. Sensorineural hearing loss was more prevalent (66.26%) of most frequently with bilateral hearing loss of 91.56% and 26.50% with mild degree. The statistical analysis showed that the variable DM was associated with the high frequency of hearing loss in the elderly, and according to the multiple logistic regression, the risk factors are independent of the hearing loss only for age and exposure to occupational noise. Conclusions There was a statistically significant difference between hearing loss at high frequencies and the risk factors, that is, age and DM.

Can parenting practices predict externalizing behavior problems among children with hearing impairment?

Objective: To identify possible differences in the level of externalizing behavior problems among children with and without hearing impairment and determine whether any relationship exists between this type of problem and parenting practices. Methods: The Behavior Assessment System for Children was used to evaluate externalizing variables in a sample of 118 boys and girls divided into two matched groups: 59 with hearing disorders and 59 normal-hearing controls. Results: Significant between-group differences were found in hyperactivity, behavioral problems, and externalizing problems, but not in aggression. Significant differences were also found in various aspects of parenting styles. A model for predicting externalizing behavior problems was constructed, achieving a predicted explained variance of 50%. Conclusion: Significant differences do exist between adaptation levels in children with and without hearing impairment. Parenting style also plays an important role.

Caracterização do perfil auditivo de frentistas de postos de combustível / Characterization of hearing profile of gas station attendants

RESUMO Introdução Pesquisas voltadas para as populações com baixas exposições a solventes, ou exposições dentro dos níveis de tolerância permitidos em âmbito ocupacional ainda são restritas. Objetivo Caracterizar o perfil auditivo de frentistas de postos de combustíveis. Métodos Estudo transversal, constituído por dois grupos, pareados por gênero e idade: Grupo Controle - 23 indivíduos sem exposição a ruído ou agentes químicos; Grupo Experimental - 21 frentistas de postos de combustíveis. Foi realizada avaliação audiológica, composta por audiometria tonal liminar, logoaudiometria e medidas de imitância acústica. A análise estatística utilizou cálculo de média, desvio padrão, valor mínimo e máximo, teste Qui-quadrado e coeficiente de correlação de Pearson. O nível de significância adotado foi de 5%. Resultados Foram verificadas alterações auditivas nos frentistas, caracterizadas por comprometimento no sistema auditivo periférico, sugerindo ação tóxica da exposição a combustíveis. Houve correlação entre idade e tempo de exposição a solvente. Na comparação entre os grupos, o reflexo acústico demonstrou maior número de alterações no grupo experimental, com diferença para os reflexos acústicos ipsilaterais da orelha direita e contralaterais da orelha esquerda. Conclusão Não houve diferença entre os grupos para os limiares auditivos, porém, a diferença verificada nos reflexos acústicos ipsilaterais e contralaterais no grupo experimental sugere comprometimento retrococlear. Diante das evidências observadas neste estudo, considera-se relevante incluir a pesquisa do reflexo acústico na avaliação auditiva dos frentistas, bem como a integração desta categoria profissional aos programas de prevenção de perda auditiva.

ABSTRACT Introduction Researches into populations with low solvent exposures, or exposures within tolerance levels allowed in the occupational field are still restricted. Purpose To characterize the hearing profile of gas station attendants. Methods Cross-sectional study, constituted of two groups, matched by gender and age: Control Group - 23 subjects without exposure to noise or chemicals; Experimental Group - 21 gas station attendants. An audiological evaluation was performed, composed by pure tone audiometry, speech audiometry and acoustic impedance tests. The statistical analysis used average calculation, standard deviation, minimum and maximum value; Chi-square Test and Pearson’s correlation coefficient. The significance level was 5%. Results Hearing loss was verified in gas station attendants characterized by impairment of the peripheral auditory system, suggesting toxic effects of exposure to fuels. There was a correlation between age and solvent exposure time. Comparing the groups, the acoustic reflex showed more alterations in the experimental group, with a difference for the ipsilateral acoustic reflexes of the right ear and contralateral ones of the left ear. Conclusion There was no difference between the groups for the hearing thresholds; however, the difference observed in the ipsilateral and contralateral acoustic reflexes in the experimental group suggests retrocochlear impairment. Due to the evidence observed in this study, it is considered relevant to include the acoustic reflex research in the auditory evaluation of the gas station attendants, as well as the integration of this professional category into hearing loss prevention programs.

Tubos de timpanostomía en niños / Tympanostomy tubes in children

La colocación de tubos de timpanostomía (TT) es la cirugía ambulatoria más frecuentemente practicada en niños. Su objetivo es lograr una adecuada ventilación del oído medio, función normalmente llevada a cabo por la trompa de Eustaquio (TE). La anatomía de la TE en la población pediátrica diiere del adulto, por lo que sus funciones son menos eicaces. La pobre ventilación del oído medio es en parte responsable de la instauración de otitis media aguda. La otitis media aguda recurrente y otitis media con efu - sión pueden afectar la calidad de vida de los pacientes, causando déicit auditivos, retraso del desarrollo del habla y escolar o incluso complicándose en infecciones más severas. La miringotomía con colocación de tubos de ventilación pretende subrogar la función de la TE, con el objetivo de disminuir la incidencia de otitis media, disminuir la severidad de episodios subsecuentes y de restaurar la audición...(AU)

Introdução: Mucopolissacaridose (MPS) é um conjunto de doenças raras causadas pela deficiência de enzimas lisossômicas levando ao acúmulo de glicosaminoglicanos (GAG) em órgãos e tecidos, responsáveis pelo quadro clínico multissistêmico, crônico e progressivo. O comprometimento auditivo é frequente. Objetivo: Avaliar manifestações auditivas de pacientes com MPS. Metodologia: Estudo descritivo, série de casos do comprometimento auditivo de pacientes com MPS. Foi realizada avaliação retrospectiva através de revisão de prontuário e avaliação prospectiva de dezembro de 2012 a outubro de 2014. Foram analisados a primeira e a última avaliação otorrinolaringológica (ORL) e audiológica realizada. Resultados: A principal queixa auditiva foi a hipoacusia. Aperdaauditiva estava presente em quase todos os pacientes, sendo que a perda auditiva condutiva foi a mais frequente, especialmente nos pacientes com MPS VI. Conclusão: A perda auditiva é muito frequente em pacientes com MPS, devendo o acompanhamento audiológico ser realizado precocemente.

Introduction: Mucopolysaccharidosis (MPS) is a set of rare diseases caused by deficiency of lysosomal enzymes leading to accumulation of glicosaminoglicanos (GAG) in tissues and organs responsible for the multisystemic clinical, chronic and progressive symptons. Objective: Todescribe the profile of otorhinolaryngological clinical examination and audiology tests of patients with MPS disease. Methods:Study of case series. The evaluation was performed, at the beginning, in 31 patients with MPS I, II, IIIA, IV and VI. Results: The most common hearing complaint was hearing loss and it was confirmed by audiology tests in almost 100% of patients, mostly with condutive hearing loss. Conclusions: It is important to evaluate the complaints, physical examination and audiology tests in MPS disease. Otorhinolaryngologist should be part of professional group that follow these patients in order to better monitor their hearing and provide early hearing rehabilitation.

Caracterização demográfica, clínica e genética da deficiência auditiva na Bahia / Demographic and clinical characteristics and genetic hearing impairment in Bahia

Dados do censo demográfico brasileiro de 2010 demonstram que 5,5% da população baiana possui alguma dificuldade auditiva (DA) (IBGE, 2010). No entanto, dados mais detalhados sobre a DA no estado da Bahia são muito escassos. Por isso, tem-se como objetivo desse trabalho traçar o perfil dos pacientes encaminhados para concessão de aparelhos de amplificação sonora individual em uma unidade do SUS de referência estadual do estado da Bahia, analisando as diferentes variáveis: faixa etária, sexo, escolaridade, tipo e grau da perda auditiva, histórico familiar da DA, consanguinidade entre os pais e relato de fatores associados com a DA. Para isso foi realizado estudo observacional de corte transversal, com análise de 2.711 prontuários do setor de reabilitação auditiva Cepred no período de um ano, entre os anos 2012 e 2013. Foram identificados possíveis casos de etiologia genética, cuja base molecular foi investigada através da análise das mutações: c.35delG no gene GJB2 (rs80338939), as deleções del(GJB6-13S1830) e del (GJB6-D13S1854)...

Brazilian demographic census showed that 5.5% of Bahia's population has some hearing difficulty (HI) (IBGE, 2010). However, there are not detailed data about the HI in Bahia. So, present study objectived establish the profile of patients referred for granting individual sound amplification devices in a SUS unit of state of Bahia reference, analyzing the different variables: age, gender, education, type and degree of hearing loss, family history of AD, consanguinity between parents and account factors associated with AD. For that, it was conducted a one year observational cross-sectional study, for analysis of 2711 medical records of the hearing rehabilitation sector of the Cepred. According medical records it was possible suggest genetic etiology on some cases. The genetic etiology was confirmed molecularly. First, it was investigated four mutations: c.35delG GJB2 (rs80338939) gene, the deletion del (GJB6-13S1830) and del (GJB6-D13S1854)...

Auditory characteristics of individuals with temporomandibular dysfunctions and dentofacial deformities

OBJECTIVE: To investigate whether there is any relationship between otological as well as vestibular symptoms, audiological findings and type of temporomandibular disorder (articular, muscular and mixed); and to check the distribution of the temporomandibular disorders (TMD) dysfunction degree in the research population. METHODS: A retrospective study involving 30 patients of both sexes, aged between 18 and 49 years old, diagnosed with TMD and dentofacial deformities, who were subject to clinical evaluation (muscle palpation, auscultation of temporomandibular joint during mandibular motion and measurement of jaw movement), audiological testing (pure tone audiometry and immittance testing) and two questionnaires, one on otological and vestibular symptoms and the other on TMD anamnesis. Based on both the anamnesis questionnaire and the clinical assessment, the subjects were divided according to the type and degree of TMD dysfunction (mild, moderate and severe), and compared regarding the occurrence of auditory signs and symptoms, vestibular symptoms and audiological findings according to TMD type. RESULTS: The anamnesis questionnaire demonstrated higher prevalence (83.33%) of severe TMD. Subjects with mixed TMD had more complaints about hypoacusis than those with muscular TMD (p < 0.05). The results showed no change in either audiological and immittance testing for all assessed individuals. CONCLUSION: Otological symptoms are present in subjects with TMD and dentofacial deformities, regardless of the classification of TMD (articular, muscular or mixed). Those with mixed TMD may have higher incidence of complaints about hypoacusis than subjects with muscular TMD. Further studies are needed to investigate the relationship between otological symptoms and the different types of TMD.

OBJETIVO: investigar se há relação entre os sintomas otológicos, vestibulares, achados audiológicos e o tipo de disfunção temporomandibular (articular, muscular e misto), e verificar a distribuição do grau de disfunção da DTM nessa população. MÉTODOS: estudo retrospectivo, envolvendo 30 pacientes com deformidades dentofaciais diagnosticados com DTM, de ambos os sexos, entre 18 e 49 anos de idade, submetidos a avaliação clínica (palpação muscular, ausculta da articulação temporomandibular durante os movimentos mandibulares e mensuração da movimentação da mandíbula), exame audiológico (audiometria tonal limiar e imitanciometria) e a dois questionários, sendo um sobre sintomas otológicos e vestibulares e outro anamnético da DTM. A partir do questionário anamnético e da avaliação clínica, os sujeitos foram divididos conforme o tipo e o grau da disfunção da DTM (leve, moderado e severo), e comparados quanto à ocorrência dos sinais e sintomas auditivos, vestibulares e achados audiológicos, de acordo com o tipo de DTM. RESULTADOS: houve maior prevalência (83,33%) de DTM severa de acordo com questionário anamnético. Sujeitos com DTM mista apresentaram mais queixas de hipoacusia do que aqueles com DTM muscular (p < 0,05). Os resultados evidenciaram ausência de alterações nos exames audiológico e imitanciométrico para todos os indivíduos avaliados. CONCLUSÃO: sintomas auditivos estão presentes nos sujeitos com DTM e deformidades dentofaciais, independentemente da classificação da DTM (articular, muscular ou mista), e aqueles com DTM mista podem apresentar maior ocorrência de queixa de hipoacusia do que sujeitos com DTM muscular. Estudos futuros são necessários para investigar a relação entre a sintomatologia auditiva e os diversos tipos de DTM.

Cochlear implants and bacterial meningitis: A speech recognition study in paired samples

Introduction: Cochlear implants may guarantee sound perception and the ability to detect speech at a close-to-normal hearing intensity; however, differences have been observed among implantees in terms of performance on discrimination tests and speech recognition. Objective: To identify whether patients with post-meningitis deafness perform similarly to patients with hearing loss due to other causes. Method: A retrospective clinical study involving post-lingual patients who had been using Nucleus-22 or Nucleus-24 cochlear implants for at least 1 year. These patients were matched with respect to age (± 2 years), time since the onset of deafness (± 1 year), and the duration of implant use with implant users who had hearing loss due to other causes. Speech perception was assessed using the Portuguese version of the Latin-American Protocol for the Evaluation of Cochlear Implants. Results: The sample consisted of 52 individuals (26 in each of the 2 groups). The post-meningitic group had a median of 18.5 active electrodes. The group with hearing loss due to other causes had a median of 21, but no significant statistical difference was observed (p = 0.07). The results of closed- and open-set speech recognition tests showed great variability in speech recognition between the studied groups. These differences were more pronounced for the most difficult listening tasks, such as the medial consonant task (in the vowel-consonant-vowel format). Conclusion: Cochlear implant recipients with hearing loss due to bacterial meningitis, who had been using the device for 1 year performed more poorly on closed- and open-set speech recognition tests than did implant recipients with hearing loss due to other causes...

Prevalência de queixa de zumbido e prováveis associações com perda auditiva, diabetes mellitus e hipertensão arterial em pessoas idosas / Prevalence of tinnitus complaints and probable association with hearing loss, diabetes mellitus and hypertension in elderly

OBJETIVO: Verificar a prevalência de queixa de zumbido e a possível associação com perda auditiva, diabetes mellitus e hipertensão arterial em pessoas idosas. MÉTODOS: Estudo transversal com indivíduos com idade superior a 60 anos, submetidos à avaliação audiológica (audiometria tonal e história), e questionário de comorbidades. Foram avaliados 519 indivíduos de ambos os gêneros com mediana de idade de 69 anos. Foram excluídos os indivíduos que não participaram do exame audiométrico, totalizando então 498 sujeitos. Foram aplicados os testes estatísticos apropriados para analisar a queixa de zumbido e os fatores associados. RESULTADOS: Observou-se a prevalência de 42,77% de queixa de zumbido, sendo 58,68% zumbido bilateral e 41,31% zumbido unilateral. Houve diferença entre o zumbido e a perda auditiva, porém não houve diferença entre a queixa de zumbido e hipertensão arterial e entre zumbido e o diabetes mellitus isoladamente. CONCLUSÃO: A queixa de zumbido tem prevalência importante nos idosos. Houve diferença entre zumbido e perda auditiva, ocorrendo associação entre o lado afetado pelo zumbido e o lado da perda auditiva. Apenas a associação das comorbidades de presença de diabetes mellitus e de hipertensão arterial é fator independente de risco para o zumbido.

PURPOSE: To assess the prevalence of tinnitus and possible association with hearing loss, diabetes mellitus and hypertension in elderly. METHODS: Cross-sectional study with individuals older than 60 years who underwent audiological evaluation (pure tone audiometry and history) and answered a comorbidity questionnaire. We evaluated 519 subjects of both genders with a median age of 69 years. Individuals who did not participate in the audiometric test were excluded, then totaling 498 subjects. We applied the appropriate statistical tests to analyze the tinnitus and associated factors. RESULTS: The prevalence of 42.77% of tinnitus was found, being 58.68% bilateral tinnitus and 41.31% unilateral tinnitus. There was a difference between tinnitus and hearing loss, but there was no difference between tinnitus and hypertension and between tinnitus and diabetes mellitus alone. CONCLUSION: The prevalence of tinnitus is significant in the elderly. There are differences between tinnitus and hearing loss, with association between the side affected by tinnitus and the side of hearing loss. Only the association of comorbidity of diabetes mellitus and hypertension is an independent risk factor for tinnitus.

Análise sistemática dos benefícios do uso do implante coclear na produção vocal / Systematic analysis of the benefits of cochlear implants on voice production

OBJETIVO: Realizar uma revisão sistemática de pesquisas relacionadas às características vocais de crianças ou adultos com deficiência auditiva usuários de implante coclear. ESTRATÉGIAS DE PESQUISA: Foi realizada uma busca com os descritores voz, qualidade da voz e implante coclear, e seus respectivos correspondentes na língua inglesa, nas bases de dados Web of Science, Bireme, portal de teses e dissertações da USP e banco de teses e dissertações da CAPES. CRITÉRIOS DE SELEÇÃO: Os critérios adotados incluíram título condizente com a proposta deste estudo, casuística necessariamente englobando crianças ou adultos com deficiência auditiva de grau severo a profundo, pré ou pós-linguais, usuários de implante coclear e que tenham passado por análise perceptivo-auditiva e/ou acústica da qualidade vocal. RESULTADOS: Vinte e sete trabalhos foram classificados seguindo-se os níveis de evidências e indicadores de qualidade empregados pela American Speech-Language-Hearing Association (ASHA). Os desenhos dos trabalhos analisados foram considerados de média e baixa evidência científica. Seis trabalhos foram classificados como nível de evidência IIb, 20 como III, e um como IV. CONCLUSÃO: A qualidade vocal da criança ou adulto com deficiência auditiva usuário de implante coclear tem sido estudada em pequena escala. Não há um número efetivo de estudos com alto índice de evidência que demonstrem com precisão os efeitos do implante coclear na qualidade vocal desses indivíduos.

PURPOSE: To perform a systematic analysis of the research regarding vocal characteristics of hearing impaired children or adults with cochlear implants. RESEARCH STRATEGY: A literature search was conducted in the databases Web of Science, Bireme, and Universidade de São Paulo's and CAPES' thesis and dissertations databases using the keywords voice, voice quality, and cochlear implantation, and their respective correspondents in Brazilian Portuguese. SELECTION CRITERIA: The selection criteria included: title consistent with the purpose of this review; participants necessarily being children or adults with severe to profound pre-lingual or post-lingual hearing loss using cochlear implants; and data regarding participants' performance on perception and/or acoustic analysis of the voice. RESULTS: Twenty seven papers were classified according to the levels of evidence and quality indicators recommended by the American Speech-Language-Hearing Association (ASHA). The designs of the studies were considered of low and medium levels of evidence. Six papers were classified as IIb, 20 as III, and one as IV. CONCLUSION: The voice of hearing impaired children and adults with cochlear implants has been little studied. There is not an effective number of studies with high evidence levels which precisely show the effects of the cochlear implantation on the quality of voice of these individuals.

Avaliação de dois testes auditivos centrais em idosos sem queixas / Assessment of two central auditory tests in elderly patients without hearing complaints

Na população idosa, distúrbios da inteligibilidade de fala podem ter causas periféricas ou centrais. A assimetria em testes dicóticos verbais aumenta com a idade e reflete falha na transferência inter-hemisférica e nas funções cognitivas. OBJETIVO: Investigar o desempenho de idosos, sem queixas auditivas, em dois testes de processamento auditivo. FORMA DO ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: Foram avaliados 22 voluntários, com idades entre 55 e 75 anos, com limiares auditivos máximos de 40 dB NA até 4000Hz, índice de reconhecimento de fala acima de 80 por cento e audição simétrica bilateralmente. Aplicaram-se testes de fala com ruído e dicótico de dissílabos alternados (SSW). A análise dos dados comparou gênero, orelhas e grupos etários. RESULTADOS: Não houve diferença entre os gêneros para nenhum dos testes. A orelha esquerda teve desempenho inferior à orelha direita na condição competitiva do teste SSW. Os participantes com idade acima de 65 anos apresentaram desempenho pior em ambos os testes quando comparados com indivíduos de 55 a 64 anos. CONCLUSÃO: O desempenho dos testes auditivos centrais piora com a idade. A introdução de testes dicóticos na bateria de avaliação auditiva de idosos pode contribuir para a identificação precoce de processos degenerativos característicos do envelhecimento.

Speech understanding disorders in the elderly may be due to peripheral or central auditory dysfunctions. Asymmetry of results in dichotic testing increases with age, and may reflect on a lack of inter-hemisphere transmission and cognitive decline. AIM: To investigate auditory processing of aged people with no hearing complaints. STUDY DESIGN: clinical prospective. MATERIALS AND METHODS: Twenty-two voluntary individuals, aged between 55 and 75 years, were evaluated. They reported no hearing complaints and had maximal auditory thresholds of 40 dB HL until 4 KHz, 80 percent of minimal speech recognition scores and peripheral symmetry between the ears. We used two kinds of tests: speech in noise and dichotic alternated dissyllables (SSW). Results were compared between males and females, right and left ears and between age groups. RESULTS: There were no significant differences between genders, in both tests. Their Left ears showed worse results, in the competitive condition of SSW. Individuals aged 65 or older had poorer performances than those aged 55 to 64. CONCLUSION: Central auditory tests showed worse performance with aging. The employment of a dichotic test in the auditory evaluation setting in the elderly may help in the early identification of degenerative processes, which are common among these patients.

Implante coclear para el manejo del tinnitus intratable en pacientes con hipoacusia unilateral: [revisión] / Cochlear implant for the management of intractable tinnitus in patients with unilateral hearing loss: [review]

El tinnitus es una condición frecuente en la población y altamente invalidante. Se han aplicado numerosas modalidades de tratamiento, sin embargo aún no hay consenso sobre un agente terapéutico efectivo. Incidentalmente se ha visto que los pacientes con hipoacusia profunda bilateral y tinnitus que han recibido un implante coclear, refieren mejoría de este síntoma en un alto porcentaje. Esto ha llevado a la indicación del implante coclear en casos de tinnitus intratable. Estudios recientes, han demostrado que el uso de esta audioprótesis aparece como una alternativa prometedora para el manejo del tinnitus en pacientes con sordera unilateral.

Tinnitus is a common and highly disabling condition in the population. Many forms of treatments have been implemented. However, there is no consensus yet on an effective therapeutic agent. Incidentally, it has been observed that patients with bilateral profound hearing loss and tinnitus that have received a cochiear implant, report improvement of this symptom in a high percentage. This has led to the indication of cochiear implant in intractable tinnitus cases. Recent studies have shown that using this hearing aid appears as a promising alternative for the management of tinnitus in patients with unilateral deafness.
