Precisión diagnóstica de una versión abreviada de las pruebas de patrones de frecuencia y patrones de duración para la evaluación del ordenamiento auditivo temporal / Diagnostic accuracy of an abbreviated version of the frequency pattern and duration pattern tests for the evaluation of auditory temporal ordering

Introducción: Las pruebas de patrones de frecuencia y patrones de duración son consideradas los gold standard de evaluación del ordenamiento auditivo temporal. A pesar de su amplia difusión, la extensión y duración de estas pruebas dificultan su utilización dentro de baterías de evaluación del procesamiento auditivo. Sin embargo, dadas sus características estructurales, pareciera ser posible reducirlas sin perder su precisión diagnóstica. Objetivo: Determinar las propiedades diagnósticas de versiones abreviadas de las pruebas de patrones de frecuencia y patrones de duración. Material y Método: Se realizó un estudio transversal de diseño observacional analítico. Se evaluaron 166 oídos de 88 sujetos con edades entre 18 y 33 años, los cuales fueron clasificados con normalidad o alteración del ordenamiento auditivo temporal. Se utilizaron las pruebas originales de Auditec de 30 ítems por oído como referencia y los primeros 10 ítems de cada oído como versión abreviada. Resultados: La versión abreviada de la prueba de patrones de frecuencia obtuvo una sensibilidad de un 94,33%, una especificidad del 94,29% y un área bajo la curva ROC de 0,980. La versión abreviada de la prueba de patrones de duración obtuvo una sensibilidad de un 89,58%, especificidad del 71,88% y un área bajo la curva ROC de 0,916. Ambas versiones tuvieron un índice de concordancia adecuado. Conclusiones: Las versiones abreviadas de la prueba de patrones de frecuencia y patrones de duración cuentan con excelentes propiedades diagnósticas para la evaluación del ordenamiento auditivo temporal y pueden ser utilizadas de manera intercambiable con las versiones originales.

Introduction: The frequency and duration pattern tests are considered the gold standard for assessing auditory temporal ordering. Despite their wide dissemination, the length and duration of these tests make it difficult to use them within auditory processing assessment batteries. However, given their structural characteristics, reducing them without losing their diagnostic accuracy seems possible. Aim: Determine the diagnostic properties of abbreviated versions of the Frequency Patterns and Duration Patterns tests. Material and Method: A cross-sectional study with an analytical observational design was carried out. 166 ears of 88 subjects aged between 18 and 33 years were evaluated, classified as normal or altered in temporal auditory order. The original Auditec tests of 30 items per ear were used as a reference, and the first 10 items of each ear as an abbreviated version. Results: The abbreviated version of the frequency patterns test obtained a sensitivity of 94.33%, a specificity of 94.29%, and an area under the ROC curve of 0.980. The abbreviated version of the duration pattern test obtained a sensitivity of 89.58%, a specificity of 71.88%, and an area under the ROC curve of 0.916. Both versions had an adequate concordance index. Conclusion: The abbreviated versions of the frequency patterns and duration patterns test have excellent diagnostic properties for assessing auditory temporal ordering and can be used interchangeably with the original versions.

Evaluación de la competencia pragmática de cuatro adultos españoles con discapacidad auditiva congénita a través del Protocolo Rápido de Evaluación Pragmática - Revisado / Assessing the pragmatic competence of four spanish adults with congenital hearing loss through Protocolo Rápido de Evaluación Pragmática - Revisado

Numerosos estudios apuntan a las dificultades del lenguaje oral que pueden presentar las personas con discapacidad auditiva a lo largo de su desarrollo. No obstante, se conoce poco acerca del nivel de competencia pragmática que alcanzan y cómo esta área se desarrolla. En esta investigación se pretenden abordar las características pragmáticas de cuatro adultos españoles con discapacidad auditiva congénita a través del Protocolo Rápido de Evaluación Pragmática Revisado (PREP-R), que evalúa diferentes niveles de pragmática: textual, enunciativa e interactiva y, además,aporta un índice de habilidad pragmática general, específica y de base gramatical. Los participantes fueron evaluados mediante videograbaciones de muestras de lenguaje espontáneo en conversación con un familiar. Los resultados indican que, en general, los cuatro sujetos presentan un buen nivel de competencia pragmática, que se manifiesta a la hora de ajustar los actos de habla. Sin embargo, para regular su lenguaje, tienden a utilizar conductas compensatorias como: estrategias verbales que les permiten ganar tiempo extra para la construcción de sus emisiones, empleo de actos verbales y/o paraverbales compensatorios y el uso de gestos que completan su producción verbal. Estos datos indican que, aunque los participantes de este estudio presentan buenas habilidades pragmáticas, es necesario seguir desarrollando estrategias a nivel de intervención que les permitan comunicarse sin dificultades en diferentes contextos y con distintos interlocutores.

Numerous studies reveal the oral language difficulties that people with hearing loss may present throughout their development. However, little is known about the level of pragmatic competence they achieve and how this area evolves. This research aims to address the pragmatic characteristics of four Spanish adults with congenital hearing loss through Protocolo Rápido de Evaluación Pragmática -Revisado (PREP-R, which can be translated as Quick Protocol for Pragmatic Evaluation -Revised). This test assesses different levels of pragmatics: textual, enunciative, and interactional, and also provides an indicator for general, specific, and grammatically-based pragmatic ability. The participants were assessed by videotaping spontaneous speech samples in conversation with a family member. The results indicate that, in general, the four subjects present an adequate level of pragmatic competence, which is manifested in their adjustment of speech acts. Nevertheless, they show a tendency to use compensatory behaviors toregulate their speech, such as verbal strategies that allow them to gain extra time to construct their utterances, compensatory verbal and/or paraverbal acts, and gestures that complement their verbal productions. These data indicate that, although the participants of this study show good pragmatic skills, it is necessary to continue developing intervention strategies that allow them to communicate without difficulties in different contexts and with different communication partners.

Abstract Introduction: Auditory processing disorder in children is related to language disorders, poor academic performance, learning disorders, and psychosocial difficulties. There is international consensus on the usefulness of behavioral tests for their evaluation and diagnosis. Aim: To establish normative values for auditory processing behavioral tests in Chilean pediatric population with normal neurodevelopment and hearing thresholds. Material and Method: An observational cross-sectional study was carried out. One hundred fifty-three subjects between 7 and 12 years old from the Metropolitan Region participated. Frequency pattern tests, filtered speech, and dichotic digits were studied. Fractional regression models were built to estimate the normative values, and cut-off scores were also calculated at the 2.5, 5, and 10 percentiles. Results: There were no significant differences between ears for the tests studied except for the dichotic digits test. Single models were built for the frequency and filtered speech patterns tests and independent models for each ear for the dichotic digit test. All estimates were significant and had acceptable levels of precision. Conclusion: The normative values and cut-off scores were obtained for the three tests studied. The values obtained were similar to those reported in other populations considering the effects of ear, age, sex, and education.

Impacto da exposição à sífilis materna no sistema auditivo de recém-nascidos / Impact of exposure to maternal syphilis on the newborn's auditory system

RESUMO Objetivo Avaliar os achados audiológicos de recém-nascidos expostos à sífilis materna, tratada adequadamente na gestação. Métodos Estudo de coorte única não concorrente, realizado em um hospital público. Fizeram parte da amostra recém-nascidos filhos de mães que apresentaram sorologia positiva para sífilis e que realizaram o tratamento adequado durante a gestação, compondo o grupo estudo, e recém-nascidos sem indicadores de risco para deficiência auditiva, grupo comparação. Resultados Participaram do estudo 90 recém-nascidos, sendo 41 do grupo estudo e 49 do grupo comparação. No exame de emissões otoacústicas por estímulo transiente, todos apresentaram presença de resposta bilateralmente e, na comparação das amplitudes de respostas nas bandas de frequências de 3,0 kHz, 3,5 kHz e 4,0 kHz observou-se menor amplitude de resposta no grupo exposto, com diferença estatisticamente significativa para a frequência de 4 kHz à direita. Na análise das respostas do exame de potencial evocado auditivo de tronco encefálico, não se observou assimetria de resposta entre as orelhas que sugerisse alteração retrococlear e nem diferenças nos valores das latências absolutas ou intervalos interpicos, entre os grupos. Conclusão As respostas eletroacústicas foram discretamente inferiores nos recém-nascidos exposto à sífilis materna, enquanto que as respostas eletrofisiológicas foram semelhantes às encontradas na população de baixo risco para deficiência auditiva.

ABSTRACT Purpose To evaluate the audiological findings of newborns exposed to maternal syphilis, properly treated during pregnancy. Methods This was a single, non-concurrent cohort study conducted in a public hospital. The sample included newborns whose mothers had positive syphilis serology and who underwent adequate treatment during pregnancy, composing the study group, and newborns without risk indicators for hearing loss, as a comparison group. Results Ninety newborns participated in the study, 41 were the study group and 49 were the comparison group. In the transient evoked otoacoustic emissions test, all newborns showed a bilateral response, and when comparing the amplitudes of responses in the 3.0 kHz, 3.5 kHz and 4.0 kHz frequency bands, a smaller amplitude of response in the studied group with a statistically significant difference for the frequency of 4 kHz on the right was observed. An analysis of the response of the brainstem auditory evoked potential test showed no asymmetry of response between the ears that suggest a retrocochlear alteration, nor difference in the values of absolute latencies or interpeak intervals between groups. Conclusion The electroacoustic responses were slightly lower in newborns exposed to maternal syphilis, whereas their electrophysiological responses were similar to those found in the population at low risk for hearing loss.

Análise das emissões otoacústicas transitórias por banda de frequência em adolescentes com diabetes mellitus tipo 1 / Transient otoacoustic emissions analysis by frequency bands in adolescents with type 1 diabetes mellitus

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. (AU)

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)

Pruebas de fusión auditiva y de detección de gaps: evaluación de la resolución auditiva temporal / Auditory fusion and gap detection tests: assessment of auditory temporal resolution

RESUMEN Dentro de los distintos mecanismos del procesamiento auditivo, los aspectos temporales de la audición se consideran como uno de los más relevantes ya que serían la base para el adecuado funcionamiento del resto de los procesos auditivos centrales. Los aspectos temporales de la audición se definen como los procesos implicados en la percepción del sonido y de sus variaciones en el dominio temporal. Uno de los aspectos temporales más ampliamente estudiados, por su relevancia en la percepción y discriminación de los sonidos del habla, ha sido la resolución auditiva temporal, que se refiere a la mínima cantidad de tiempo necesaria para que un individuo pueda discriminar entre dos estímulos auditivos distintos. En los últimos años, se ha utilizado principalmente metodologías de detección de fusión auditiva y detección de gaps para su evaluación. Ambas han dado origen a una serie de pruebas psicoacústicas, de las cuales destacan tres: la prueba de fusión auditiva revisada, la prueba de detección de gaps aleatorios y la prueba de gaps en ruido. Se recomienda la incorporación de alguna de estas pruebas en la evaluación clínica ante la sospecha de trastornos del procesamiento auditivo.

ABSTRACT Among the different mechanisms of auditory processing, the temporal aspects of hearing are considered as one of the most relevant since they would be the basis for the proper functioning of the rest of the central auditory processes. Temporal aspects of hearing are defined as the processes involved in the perception of sound and its variations in the temporal domain. One of the most widely studied temporal aspects due to its relevance in the perception and discrimination of speech sounds has been the temporal auditory resolution, which refers to the minimum amount of time necessary for an individual to discriminate between two different auditory stimuli. In recent years, the mainly used methodologies for evaluate it are the hearing fusion detection and gaps detection. Both methodologies have given rise to several psychoacoustic tests, of which three have been highlighted: the revised auditory fusion test, the random gap detection test and gaps in noise test. It is recommended the incorporation of any of these tests in the clinical evaluation of suspected auditory processing disorders.

Electroacoustic verification of frequency modulation systems in cochlear implant users / Verificação eletroacústica de sistemas de frequência modulada em usuários de implante coclear

Abstract Introduction: The frequency modulation system is a device that helps to improve speech perception in noise and is considered the most beneficial approach to improve speech recognition in noise in cochlear implant users. According to guidelines, there is a need to perform a check before fitting the frequency modulation system. Although there are recommendations regarding the behavioral tests that should be performed at the fitting of the frequency modulation system to cochlear implant users, there are no published recommendations regarding the electroacoustic test that should be performed. Objective: Perform and determine the validity of an electroacoustic verification test for frequency modulation systems coupled to different cochlear implant speech processors. Methods: The sample included 40 participants between 5 and 18 year's users of four different models of speech processors. For the electroacoustic evaluation, we used the Audioscan Verifit device with the HA-1 coupler and the listening check devices corresponding to each speech processor model. In cases where the transparency was not achieved, a modification was made in the frequency modulation gain adjustment and we used the Brazilian version of the "Phrases in Noise Test" to evaluate the speech perception in competitive noise. Results: It was observed that there was transparency between the frequency modulation system and the cochlear implant in 85% of the participants evaluated. After adjusting the gain of the frequency modulation receiver in the other participants, the devices showed transparency when the electroacoustic verification test was repeated. It was also observed that patients demonstrated better performance in speech perception in noise after a new adjustment, that is, in these cases; the electroacoustic transparency caused behavioral transparency. Conclusion: The electroacoustic evaluation protocol suggested was effective in evaluation of transparency between the frequency modulation system and the cochlear implant. Performing the adjustment of the speech processor and the frequency modulation system gain are essential when fitting this device.

Resumo Introdução: O sistema de frequência modulada é um dispositivo que ajuda a melhorar a percepção da fala no ruído, e é considerado a abordagem mais benéfica para melhorar o reconhecimento da fala no ruído em usuários de implantes cocleares. De acordo com as diretrizes, é necessário realizar uma verificação no momento da adaptação do sistema de frequência modulada. Embora existam recomendações sobre os testes comportamentais a serem realizados na adaptação do sistema de frequência modulada para usuários de implantes cocleares, não há recomendações publicadas sobre o teste eletroacústico que deve ser realizado. Objetivo: Realizar e validar um teste de verificação eletroacústica para sistemas de frequência modulada acoplados a diferentes processadores de fala de implante coclear. Método: A amostra incluiu 40 participantes com idades entre cinco e 18 anos, usuários de quatro modelos de processadores de fala. Para a avaliação eletroacústica, utilizou-se o dispositivo Audioscan Verifit com o acoplador HA-1 e os dispositivos de verificação de escuta correspondentes a cada modelo de processador de fala. Nos casos em que a transparência não foi alcançada, foi realizada uma modificação no ajuste do ganho do sistema de frequência modulada e, em seguida, aplicou-se a versão brasileira do "Phrases in Noise Test" para avaliar a percepção da fala com ruído competitivo. Resultados: Observou-se que houve transparência entre o sistema de frequência modulada e o implante coclear em 85% dos participantes avaliados. Depois de ajustar o ganho do receptor do sistema de frequência modulada nos outros participantes, os dispositivos mostraram transparência quando o teste de verificação eletroacústica foi repetido. Observou-se também um melhor desempenho na percepção da fala no ruído após um novo ajuste, ou seja, nesses casos a transparência eletroacústica resultou em transparência comportamental. Conclusão: O protocolo de avaliação eletroacústica sugerido foi eficaz para avaliar a transparência entre o sistema de frequência modulada e o implante coclear. A realização do ajuste do processador de fala e o ganho do sistema de frequência modulada são essenciais no momento da adaptação deste dispositivo.

Hipotireoidismo congênito como fator de risco para os transtornos do processamento auditivo central / Congenital hypothyroidism as a risk factor for central hearing process disorders

RESUMO Objetivo: Investigar a manifestação de sintomas do transtorno do processamento auditivo central em crianças com hipotireoidismo congênito. Métodos: Estudo de caráter exploratório, descritivo e transversal com 112 pacientes com hipotireoidismo congênito com idade ≥5 anos. Realizou-se entrevista com os pais/cuidadores no momento da espera da consulta médica. Portadores de outras afecções médicas foram excluídos. Como instrumento de pesquisa utilizou-se o protocolo estruturado de anamnese para avaliação do processamento auditivo rotineiramente empregado por audiologistas. A análise estatística utilizou o teste Qui-quadrado. Resultados: A distribuição por sexo foi semelhante (meninas: 53,3%). Os casos não-disgenesia constituíram a forma fenotípica mais prevalente para o hipotireoidismo congênito (88,4%), e verificou-se que 65,3% das crianças apresentavam algum episódio de níveis séricos irregulares de hormônio tireoestimulante. Dentre as manifestações mais frequentes dos sintomas do transtorno do processamento auditivo central, as queixas relaciondas às funções cognitivas auditivas, como: figura-fundo (83,0%), atenção auditiva (75,9%) e memória auditiva (33,0%) foram as mais evidentes. Reclamações relacionadas ao rendimento escolar foram reportadas em 62,3%. Conclusões: Os dados obtidos evidenciaram altas frequências de sintomas de defasagem nas funções cognitivas relacionadas ao processamento auditivo central, em especial na atenção auditiva, figura-fundo e memória auditiva nos portadores do hipotireoidismo congênito.

ABSTRACT Objective: To investigate the presence of central auditory processing disorder symptoms in children with congenital hypothyroidism. Methods: An exploratory, descriptive, cross-sectional study of 112 patients with congenital hypothyroidism aged ≥5 years old. An interview was held with the parents/caregivers at the time of the medical consultation. Patients with other medical conditions were excluded. As a research instrument, the structured protocol of anamnesis was used to evaluate the auditory processing routinely used by audiologists. For statistical analysis, the chi-square test was used. Results: Sex distribution was similar in both boys and girls (girls: 53.3%). The most prevalent phenotypic form of congenital hypothyroidism was no dysgenesis (88.4%), and 65.3% of the children had an episode of irregular serum thyroid-stimulating hormone (TSH) levels. Among the manifestations of the most frequent central auditory processing disorder symptoms, problems were reported with regard to cognitive functions, as they related to hearing, such as figure-background ability (83.0%), auditory attention (75.9%) and auditory memory (33.0%). Complaints related to school performance were reported in 62.3% of the cases. Conclusions: The data obtained show a high frequency of lag symptoms in cognitive functions related to central auditory processing, particularly with regard to auditory attention, figure-background ability and auditory memory in patients with congenital hypothyroidism.

The use of remote microphone systems in unilateral hearing loss: a preliminary study among Brazilian children and teenagers

Abstract Due to the large number of individuals with Unilateral Hearing Loss (UHL) and the recommendation to use hearing assistive devices, studies are required to define possibilities of intervention for this population. Objective: To evaluate the performance of the Remote Microphone System (RMS) in children with UHL. Methodology: Prospective clinical study with a convenience sample. Eleven children (mean age of 9.2 years) with severe and profound sensorineural UHL, hearing aid users and enrolled in regular schools participated in the study. They were evaluated using the Hearing in Noise Test (HINT), the Classroom Participation Questionnaire (CPQ), and the Sustained Auditory Attention Ability Test (SAAAT) with RMS. Results: HINT results were analyzed using variance to three criteria of repeated measures, which revealed differences between intervention, position, and time factors and significant interaction between these three factors. The comparative analysis of the results from CPQ showed significant differences in the statistical t-test (p=<0.001) for all subscales. The analysis of variance at two repeated measures criteria used in the study of SAAAT revealed a difference between intervention and time, and both interacted significantly. Conclusion: The RMS associated with a hearing aid was effective for individuals with UHL.

Brazilian scale of hearing and language development: normality curve for infants and children from 0 to 24 months old with normal hearing

Introduction: Cochlear implants are currently the most effective technological resource to facilitate access to the hearing world for deaf people. Their use, especially when implanted early in children, reduces the impact of deafness on hearing as well as on the development of spoken language. Objective: To validate the first part of the Brazilian Scale of Hearing and Language Development (EDAL-1, in the Portuguese acronym) and to establish the normal curve in infants and children aged between 0 and 24 months old with normal hearing. Method: This is an experimental study of a descriptive nature, conducted with 92 infants and children with normal hearing. Every infant/child was evaluated audiologically, and the EDAL-1 was applied to their parents. The responses were categorized by applying the EDAL-1 every 3 months for each child. Results: The EDAL-1 was shown to be easily applied by the researcher and easily understood by the parents. It was possible to classify the sample every 3 months and describe the results. The average of the responses found in terms of scores for each age category shows an increasing scale following the evolution of the chronological age: 3 months-34.23 points; 6 months-54.68 points; 9 months-73 points; 12 months- 82.5 points; 15 months-87 points; 18 months-91 points; 21 months-92.5 points, and 24 months-95.83 points. Conclusion: The normal curve for EDAL-1 was successfully established. The averages can be considered as the standard protocol for normality, serving as a reference for comparison with other populations (AU)

Hearing assessment of neonates at risk for hearing loss at a hearing health high complexity service: an electrophysiological assessment

Introduction: Hearing is the main sensory access in the first years of life. Therefore, early detection and intervention of hearing impairment must begin before the first year of age. Objective: To analyze the results of the electrophysiological hearing assessment of children at risk for hearing loss as part of the newborn hearing screening (NHS). Methods: This is a cross-sectional study held at a hearing health public service clinic located in Brazil, with 104 babies at risks factors for hearing loss referred by public hospitals. A questionnaire was applied to parents, and the auditory brainstem response (ABR) test was held, identifying those with alterations in the results. The outcome of the NHS was also analyzed regarding risk factor, gestational age and gender. Results: Among the 104 subjects,most of them weremale (53.85%), and the main risk factor found was the admission to the neonatal intensive care unit (NICU) for a period longer than 5 days (50.93%). Eighty-five (81.73%) subjects were screened by NHS at the maternity and 40% of them failed the test. Through the ABR test, 6 (5.77%) infants evidenced sensorineural hearing loss, 4 of them being diagnosed at 4months, and 2 at 6 months of age; all of them failed the NHS and had family history and admission atNICU for over 5 days as themost prevalent hearing risks; in addition, familymembers ofall children perceived their hearing impairment. Conclusion: Advances could be observed regarding the age of the diagnosis after the implementation of the NHS held at the analyzed public service clinic (AU)

Contralateral Occlusion Test (COT): the effect of external ear canal occlusion with aging / Teste de Oclusão Contralateral (TOC): o efeito da oclusão do canal auditivo externo com a idade

ABSTRACT Purpose This study aimed to evaluate the effects of complete external ear canal occlusion on hearing thresholds with aging. The goal was to decide which tuning fork is more appropriate to use for the contralateral occlusion test (COT), in individuals of different ages. Methods Forty-two normal hearing subjects between 21 and 67 years were divided into three age groups (20-30 years, 40-50 years, and 60-70 years). Participants underwent sound field audiometry tests with warble tones, with and without ear canal occlusion. Each ear was tested with the standard frequencies (250, 500, 1000, and 2000 Hz). The contralateral ear was suppressed by masking. Results Hearing thresholds showed an increase as the frequency increased from 20.85 dB (250 Hz, 20-30 years group) to 48 dB (2000 Hz, 60-70 years group). The threshold differences between occlusion and no occlusion conditions were statistically significant and increased ranging from 11.1 dB (250 Hz, 20-30 years group) to 32 dB (2000 Hz, 20-30 years group). We found statistically significant differences for the three age groups and for all evaluations except to 500 Hz difference and average difference. The mean hearing loss produced by occlusion at 500 Hz was approximately 19 dB. We found no statistically significant differences between right and left ears and gender for all measurements. Conclusion We conclude that the use of the 512 Hz tuning fork is the most suitable for COT, and its use may allow clinicians to distinguish mild from moderate unilateral conductive hearing loss.

RESUMO Objetivo O objetivo deste estudo foi avaliar o efeito da oclusão completa do canal auditivo externo nos limiares auditivos, em indivíduos de idades distintas, para apurar qual o diapasão mais adequado na realização do teste de oclusão contralateral (TOC). Método 42 indivíduos normo-ouvintes (21-67 anos) foram divididos em três grupos etários (20-30, 40-50 e 60-70 anos). Os participantes foram avaliados com testes de audiometria tonal liminar em campo livre, com e sem oclusão completa do canal auditivo externo. Cada ouvido foi testado para as frequências 250, 500, 1000 e 2000 Hz. No ouvido contralateral, foi realizado mascaramento, para evitar a ocorrência de audição contralateral. Resultados Verificou-se aumento dos limiares auditivos, diretamente proporcional ao aumento da frequência (desde 20.85 até 48 dB). A diferença nos limiares auditivos entre a condição de oclusão e de não oclusão foi estatisticamente significativa em todas as frequências e aumentou de forma diretamente proporcional com a frequência (desde 11.1 até 32 dB). Foram também encontradas diferenças estatisticamente significativas para os três grupos etários, em todos os parâmetros, exceto na diferença a 500 Hz e na diferença total média. A perda auditiva média resultante da oclusão aos 500 Hz foi de 19 dB. Não se encontraram diferenças estatisticamente significativas entre o ouvido direito e o esquerdo, e entre o gênero. Conclusão A utilização do diapasão de 512 Hz é a mais adequada para o TOC. A sua utilização pode permitir aos clínicos, em ambiente de consulta e de forma rápida, a distinção entre perda condutiva de grau leve a moderada.

Headphone Evaluation for App-Based Automated Mobile Hearing Screening

Abstract Introduction With the need for hearing screenings increasing across multiple populations, a need for automated options has been identified. This research seeks to evaluate the hardware requirements for automated hearing screenings using a mobile application. Objective Evaluation of headphone hardware for use with an app-based mobile screening application. Methods For the purposes of this study, hEAR, a Bekesy-based mobile application designed by the research team, was compared with pure tone audiometric tests administered by an audiologist. Both hEAR and the audiologist's test used 7 frequencies (125 Hz, 250 Hz, 500 Hz, 1,000 Hz, 2000 Hz, 4,000 Hz and 8,000 Hz) adopting four different sets of commercially available headphones. The frequencies were regarded as the independent variable, whereas the sound pressure level (in decibels) was the dependent variable. Thirty participants from a university in Texas were recruited and randomly assigned to one of two groups, whose only difference was the order in which the tests were performed. Data were analyzed using a generalized estimating equation model at α = 0.05. Results Findings showed that, when used to collect data with the mobile app, both the Pioneer HDJ-2000 (Pioneer, Bunkyo, Tokyo, Japan) (p> 0.05) and the Sennheiser HD280 Pro (Sennheiser, Wedemark, Hanover, Germany) (p> 0.05) headphones presented results that were not statistically different from the audiologist's data across all test frequencies. Analyses indicated that both headphones had decreased detection probability at 4kHz and 8kHz, but the differences were not statistically significant. Conclusion Data indicate that a mobile application, when paired with appropriate headphones, is capable of reproducing audiologist-quality data.

Hearing Disorders in Congenital Toxoplasmosis: A Literature Review

Abstract Introduction Several studies show correlations between congenital toxoplasmosis and hearing loss, with a broad diversity of levels of hearing loss and specifications of hearing disorders. Objective To describe the studies found in the literature regarding hearing disorders in congenital toxoplasmosis. Data Synthesis A literature review was conducted on the Lilacs, SciELO, PubMed and Scopus databases by combining the following keywords: congenital toxoplasmosis and hearing. Based on this search strategy, 152 papers were found, the majority published on the Scopus and PubMed databases from1958 to 2015. After theapplication of the inclusion criteria, 8 articles published between 1980 and 2015 were included in the present study. Conclusion This review showed a moderate evidence of the association between hearing disorders and congenital toxoplasmosis, which is characterized by sensorineural hearing loss. However, there are gaps in the description of the specific characteristics of the type and level of hearing loss, or of other possible disorders involved in the auditory processing.

Hearing in Noise Test, HINT-Brazil, in normal-hearing children / Teste de Reconhecimento de Fala no Ruído, HINT-Brasil, em crianças normo-ouvintes

Abstract Introduction: The auditory processing is related to certain skills such as speech recognition in noise. The HINT-Brazil test allows the measurement of the Speech/Noise ratio however there are no studies in the national literature that establish parameters for the child population. Objective: To analyze the performance of normal-hearing subjects aged 8-10 years old in tasks for speech recognition in noise using HINT test. Methods: Sixty schoolchildren were evaluated. They were between 8 and 10 years of age, of both genders, and had no auditory and school complaints, with results ranking within normality for the Basic Audiological Assessment and the Dichotic Digits Test. HINT-Brazil test was applied with headphones, with the Speech/Noise ratio in conditions of frontal noise, noise to the right, and noise to the left being investigated. The software calculated the Composite Noise, which corresponds to the weighted mean of the tested conditions. Results: There was no statistically significant difference between the ears, nor between the genders. There was a statistically significant difference for age ranges of 8 and 10 years, in situations with noise, and for Composite Noise. The age group of 10 years showed better performance than the age group of 8; the age group of 9 years did not show statistically significant difference regarding the other age ranges. We suggest the values of mean and standard deviation of the Speech/Noise ratio, considering the age ranges of: 8 years - Frontal Noise: −2.09 (±1.09); Right Noise: −7.64 (±1.72); Left Noise: −7.53 (±2.80); Composite Noise: −4.86 (±1.31); 9 years - Frontal Noise: −2.82 (±0.74); Right Noise: −8.49 (±2.24); Left Noise: −8.41 (±1.75); Composite Noise: −5.63 (±1.02); 10 years - Frontal Noise: −3.01 (±0.95); Right Noise: −9.47 (±1.43); Left Noise: −9.16 (±1.65); Composite Noise: −6.16 (±0.91). Conclusion: HINT-Brazil test is a simple and fast test, and is not difficult to performed with normal-hearing children. The results confirm that it is an efficient test to be used with the age range evaluated.
