Beginner's Intelligibility Test (BIT): translation, cultural adaptation to Brazilian Portuguese and validation.

OBJECTIVE: Translate and validate the Beginner's Intelligibility Test (BIT) speech intelligibility assessment instrument into Brazilian Portuguese. METHOD: Study developed in two stages: 1st translation and cross-cultural adaptation of the Beginner's Intelligibility Test instrument into Brazilian Portuguese; 2nd application of the instrument. The second stage of the study involved 20 children using cochlear implants, aged between 4 and 11 years old, enrolled in the Cochlear Implant Program at Hospital das Clínicas de Ribeirão Preto, Faculty of Medicine of Ribeirão Preto, University of São Paulo. All data collection procedures were video, and audio recorded for analysis by judges. After orthographic transcription of each sentence repeated by the child, the judge was asked to score the participant's speech intelligibility and classify it according to criteria established in the literature. RESULTS: The translation stage took place for the four lists and 40 sentences of the Beginner's Intelligibility Test (BIT) instrument into Brazilian Portuguese, the semantic, idiomatic, experimental and conceptual equivalences were considered, and it took place without any difficulties identified by the translators. The terms used in the Portuguese language were similar and those that presented differences among the translators did not bring significant divergences to its understanding. In the inter-evaluator analysis, there was reliability between the classification and the score obtained. Different judges evaluated the same children and a concordance was observed in classification and scoring. CONCLUSIONS: Face validity of the BIT was confirmed through the understanding of each sentence of the four lists by the majority of children using cochlear implants participating in the pre-test phase. The content validity among experts was unanimous for the four lists of sentences. The Brazilian Portuguese adapted version maintained the semantic, idiomatic, conceptual, and cultural equivalence, according to the evaluation of the expert committee. EVIDENCE LEVEL: 02.

Cross-cultural adaptation of the new Reynell developmental language scales to Brazilian Portuguese

Abstract Objective: Translation and cross-cultural adaptation of The New Reynell Developmental Language Scales (NRDLS) to Portuguese spoken in Brazil. Method: We followed the steps recommended in the manual Multilingual Toolkit da NRDLS: translation of the test, adaptation of items from the scales, and use of NRDLS in a pilot study with Brazilian children. It was included a back-translation and analysis by a group of specialists in the area that helped to review the adapted version. A quantitative descriptive analysis of results from the pilot group was performed, and we used a one-way repeated measures ANOVA. Results: The Brazilian Portuguese version of the NRDLS seems very similar to the original NRDLS in terms of conceptual equivalence. The children understood well the translated and adapted words, and they had more difficulty in the last sessions. Some of the mistakes made by the children helped us to adapt specific items for a better evaluation of the abilities of Brazilian children. Conclusion: The suggestions in the Multilingual Toolkit, the input from the group of specialists, and the experience with the children in the pilot group helped the adaptation of the NRDLS to Brazilian Portuguese. The adapted version of NRDLS was effective, it reflected the gradual evolution of complexity in the scales. We suggest the application of the adapted version in a large group of children with normal development to validate it.

Cortical auditory evoked potential in babies and children listeners / Potencial evocado auditivo cortical em lactentes e crianc¸as ouvintes

Abstract Introduction Cortical auditory evoked potentials have been increasingly used in research and audiological routines. However, there is a lack of studies with a large number of children who are stratified by age group. These would help clarify the variations in latency and amplitude of cortical auditory evoked potentials, and thus help establish reference values in children of different ages. Objective To identify the variation in latency and amplitude of the cortical auditory evoked potentials and to establish reference values for the pediatric population. Methods This was a cross-sectional study. Subjects were born at term and presented with no auditory complaints. A total of 105 children, of up to 6 years and eleven months old, who were divided into 7 age groups, named 1, 2, 3, 4, 5, 6 and 7, participated in the study. The tests were carried out using Biologic Navigator Pro. Initially, brainstem auditory evoked potential testing was performed in order to investigate the electrophysiological threshold of the subjects. Then, cortical auditory evoked potentials were elicited through oddball paradigm with tone burst differing in frequency, 750 Hz (frequent) and 1000 Hz (rare), and stimuli differing in speech: /ba/ (frequent) and /da/ (rare). In this study, descriptive and comparative analyzes of tonal and speech stimuli were performed for the age groups. Results Significant differences were observed when comparing cortical auditory evoked potentials with speech stimulus in the right ear for P2 amplitude, for P1 latency the left ear, for P2 amplitude of the left ear; and for P1 amplitude of the left ear when performed with tonal stimuli. Conclusion The obtained results can be considered as reference values of latency and amplitude of cortical auditory potentials in infants and children, and be used for monitoring their cortical auditory development.

Objetivo Identificar a variação das medidas de latência e amplitude e estabelecer os valores de referência desse potencial para a população pediátrica. Método Estudo do tipo transversal. Os indivíduos nasceram a termo, com ausência de queixas auditivas. Participaram do estudo 105 crianças de até 6 anos e 11 meses, divididas em 7 grupos de idade, denominados 1, 2, 3, 4, 5, 6 e 7. Os testes foram feitos com o Biologic Navigator Pro. Inicialmente, foi realizado o potencial evocado auditivo de tronco encefálico para investigar o limiar eletrofisiológico dos indivíduos. Em seguida, o potencial evocado auditivo cortical foi feito através do paradigma de oddball com toneburst diferindo em frequência, 750 Hz (frequente) e 1.000 Hz (raro) e o estímulo na fala: / ba / (frequente) e / da / (raro). Neste estudo, foram realizadas análises descritivas e comparativas dos estímulos tonais e de fala para os grupos etários. Resultados Diferenças significantes foram observadas na comparação do potencial evocado auditivo cortical com estímulo de fala da orelha direita para amplitude de P2, para latência de P1 da orelha esquerda, para amplitude de P2 da orelha esquerda e para amplitude de P1 da orelha esquerda quando feita com estímulo tonal. Conclusão Os resultados obtidos podem ser usados como medidas de referência de latência e amplitude dos potenciais auditivos corticais em lactentes e crianças, bem como para monitorar o desenvolvimento auditivo cortical.

Is there a best side for cochlear implants in post-lingual patients? / Existe um lado melhor para implantes cocleares em pacientes pós-linguais?

Abstract Introduction: Cochlear Implant is a sensory prosthesis capable of restoring hearing in patients with severe or profound bilateral sensorineural hearing loss. Objective: To evaluate if there is a better side to be implanted in post-lingual patients. Methods: Retrospective longitudinal study. Participants were 40 subjects, of both sex, mean age of 47 years, with post-lingual hearing loss, users of unilateral cochlear implant for more than 12 months and less than 24 months, with asymmetric auditor reserve between the ears (difference of 10 dBNA, In at least one of the frequencies with a response, between the ears), divided into two groups. Group A was composed of individuals with cochlear implant in the ear with better auditory reserve and Group B with auditory reserve lower in relation to the contralateral side. Results: There was no statistical difference for the tonal auditory threshold before and after cochlear implant. A better speech perception in pre-cochlear implant tests was present in B (20%), but the final results are similar in both groups. Conclusion: The cochlear implant in the ear with the worst auditory residue favors a bimodal hearing, which would allow the binaural summation, without compromising the improvement of the audiometric threshold and the speech perception.

Resumo Introdução: O implante coclear é uma prótese sensorial capaz de restaurar a audição em pacientes com perda auditiva neurossensorial bilateral severa ou profunda. Objetivo: Avaliar se há um melhor lado para o implante coclear em pacientes pós-linguais. Método: Estudo longitudinal retrospectivo; incluiu 40 indivíduos, de ambos os sexos, média de 47 anos, com perda auditiva pós-lingual, usuários de implante coclear unilateral por mais de 12 meses e menos de 24 meses, com perda auditiva assimétrica entre as orelhas (diferença de 10 dBNA, em pelo menos uma das frequências), divididos em dois grupos. O Grupo A foi composto por indivíduos com implante coclear na orelha com melhor audição residual e Grupo B com menor audição residual em relação ao lado contralateral. Resultados: Não houve diferença estatística entre o limiar auditivo tonal antes e depois do implante coclear. Uma melhor percepção da fala nos testes pré-implante coclear foi observada no grupo B (20%), mas os resultados finais foram semelhantes em ambos os grupos. Conclusão: O implante coclear na orelha com pior audição residual favorece uma audição bimodal, o que possibilitaria a somação binaural, sem comprometer a melhora do limiar audiométrico e a percepção da fala.

Speech perception performance of subjects with type I diabetes mellitus in noise / Desempenho da percepção de fala no ruído em indivíduos com diabetes mellitus tipo I

Abstract Introduction: Diabetes mellitus (DM) is a chronic metabolic disorder of various origins that occurs when the pancreas fails to produce insulin in sufficient quantities or when the organism fails to respond to this hormone in an efficient manner. Objective: To evaluate the speech recognition in subjects with type I diabetes mellitus (DMI) in quiet and in competitive noise. Methods: It was a descriptive, observational and cross-section study. We included 40 participants of both genders aged 18-30 years, divided into a control group (CG) of 20 healthy subjects with no complaints or auditory changes, paired for age and gender with the study group, consisting of 20 subjects with a diagnosis of DMI. First, we applied basic audiological evaluations (pure tone audiometry, speech audiometry and immittance audiometry) for all subjects; after these evaluations, we applied Sentence Recognition Threshold in Quiet (SRTQ) and Sentence Recognition Threshold in Noise (SRTN) in free field, using the List of Sentences in Portuguese test. Results: All subjects showed normal bilateral pure tone threshold, compatible speech audiometry and "A" tympanometry curve. Group comparison revealed a statistically significant difference for SRTQ (p = 0.0001), SRTN (p < 0.0001) and the signal-to-noise ratio (p < 0.0001). Conclusion: The performance of DMI subjects in SRTQ and SRTN was worse compared to the subjects without diabetes.

Resumo Introdução: O diabetes mellitus (DM) é um distúrbio metabólico crônico de várias origens, que ocorre quando o pâncreas deixa de produzir insulina em quantidade suficiente ou quando o organismo não consegue responder a esse hormônio de maneira eficiente. Objetivo: Avaliar o reconhecimento de fala em indivíduos com diabetes mellitus tipo I (DMI) no silêncio e no ruído competitivo. Método: Estudo descritivo, observacional e transversal. Foram incluídos 40 participantes de ambos os sexos entre 18 e 30 anos, divididos em um grupo controle (GC) de 20 indivíduos saudáveis sem queixas ou alterações auditivas, pareados por idade e sexo com o grupo de estudo, composto por 20 indivíduos com diagnóstico de DMI. Inicialmente aplicou-se uma avaliação audiológica (audiometria tonal, logoaudiometria e imitanciometria) para todos os indivíduos; a seguir, os mesmos foram avaliados para o Limiar de Reconhecimento de Sentenças no Silêncio (LRSS) e Limiar de Reconhecimento de Sentenças no Ruído (LRSR), em campo livre, por meio do teste Lista de Sentenças em Português. Resultados: Todos os participantes apresentaram audiometria tonal dentro dos padrões de normalidade bilateralmente, logoaudiometria compatível e curva timpanométrica do tipo A. A comparação dos grupos revelou uma diferença estatisticamente significante para LRSS (p = 0,0001), LRSR (p < 0,0001) e a relação sinal-ruído (p < 0,0001). Conclusões O desempenho dos indivíduos com DMI para LRSS e LRSR foi pior em comparação com os indivíduos sem diabetes.

Auditory Alterations in Children Infected by Human Immunodeficiency Virus Verified Through Auditory Processing Test

Abstract Introduction The auditory system of HIV-positive children may have deficits at various levels, such as the high incidence of problems in the middle ear that can cause hearing loss. Objective The objective of this study is to characterize the development of children infected by the Human Immunodeficiency Virus (HIV) in the Simplified Auditory Processing Test (SAPT) and the Staggered Spondaic Word Test. Methods We performed behavioral tests composed of the Simplified Auditory Processing Test and the Portuguese version of the Staggered SpondaicWord Test (SSW). The participants were 15 children infected by HIV, all using antiretroviral medication. Results The children had abnormal auditory processing verified by Simplified Auditory Processing Test and the Portuguese version of SSW. In the Simplified Auditory Processing Test, 60% of the children presented hearing impairment. In the SAPT, the memory test for verbal sounds showed more errors (53.33%); whereas in SSW, 86.67% of the children showed deficiencies indicating deficit in figure-ground, attention, and memory auditory skills. Furthermore, there aremore errors in conditions of background noise in both age groups, where most errors were in the left ear in the Group of 8-yearolds, with similar results for the group aged 9 years. Conclusion The high incidence of hearing loss in children with HIV and comorbidity with several biological and environmental factors indicate the need for: 1) familiar and professional awareness of the impact on auditory alteration on the developing and learning of the children withHIV, and 2) access to educational plans and follow-up with multidisciplinary teams as early as possible to minimize the damage caused by auditory deficits.

Auditory Speech Perception Tests in Relation to the Coding Strategy in Cochlear Implant

Abstract Introduction The objective of the evaluation of auditory perception of cochlear implant users is to determine how the acoustic signal is processed, leading to the recognition and understanding of sound. Objective To investigate the differences in the process of auditory speech perception in individuals with postlingual hearing loss wearing a cochlear implant, using two different speech coding strategies, and to analyze speech perception and handicap perception in relation to the strategy used. Methods This study is prospective cross-sectional cohort study of a descriptive character. We selected ten cochlear implant users that were characterized by hearing threshold by the application of speech perception tests and of the Hearing Handicap Inventory for Adults. Results There was no significant difference when comparing the variables subject age, age at acquisition of hearing loss, etiology, time of hearing deprivation, time of cochlear implant use and mean hearing threshold with the cochlear implant with the shift in speech coding strategy. There was no relationship between lack of handicap perception and improvement in speech perception in both speech coding strategies used. Conclusion There was no significant difference between the strategies evaluated and no relation was observed between them and the variables studied.

P300 in individuals with sensorineural hearing loss / P300 em indivíduos com perda auditiva sensorioneural

INTRODUCTION: Behavioral and electrophysiological auditory evaluations contribute to the understanding of the auditory system and of the process of intervention. OBJECTIVE: To study P300 in subjects with severe or profound sensorineural hearing loss. METHODS: This was a descriptive cross-sectional prospective study. It included 29 individuals of both genders with severe or profound sensorineural hearing loss without other type of disorders, aged 11 to 42 years; all were assessed by behavioral audiological evaluation and auditory evoked potentials. RESULTS: A recording of the P3 wave was obtained in 17 individuals, with a mean latency of 326.97 ms and mean amplitude of 3.76 V. There were significant differences in latency in relation to age and in amplitude according to degree of hearing loss. There was a statistically significant association of the P300 results with the degrees of hearing loss (p = 0.04), with the predominant auditory communication channels (p < 0.0001), and with time of hearing loss. CONCLUSIONS: P300 can be recorded in individuals with severe and profound congenital sensorineural hearing loss; it may contribute to the understanding of cortical development and is a good predictor of the early intervention outcome. .

Analysis of otoacoustic emissions in neonates at term and preterm.

UNLABELLED: The transient evoked otoacoustic emissions (TEOAEs) have been widely used in neonatal hearing screening. OBJECTIVE: To compare the TEOAEs in newborns at term and preterm vis-à-vis the following variables: ear side, gender, frequency spectrum and gestational age. METHOD: By means of a cross-sectional cohort of 66 newborns up to the 28th day of life (41 newborns at term and 25 premature babies), we recorded TEOAEs. All the individuals did not have risk indicators for hearing loss. RESULTS: There was a signal/noise ratio improvement with frequency increase. No differences were observed between genders and between the ears, but there were differences among the children born at term and preterm in the frequency bands at 3 kHz and 4 kHz. CONCLUSION: The TEOAEs test is important for assessing the peripheral auditory system of newborns at term and preterm, making it possible to have responses regardless of gender and gestational age.

Avaliação da satisfação do usuário de aparelho de amplificação sonora / Evaluation of hearing aid user satisfaction

OBJETIVO: avaliar a satisfação do usuário de AAS (Aparelho de Amplificação Sonora) por meio da aplicação do questionário de autoavaliação IOI-HA (International Outcome Inventory For Hearing Aids) e correlacioná-lo às características dos indivíduos, da perda auditiva e do processo de adaptação do AAS. MÉTODO: foram avaliados 98 indivíduos, de ambos os gêneros, com perda auditiva neurossensorial, de um serviço público e usuários sistemáticos de AAS há, pelo menos, três meses. O questionário IOI-HA foi aplicado, como roteiro de entrevista estruturada, aos indivíduos. Correlacionaram-se as variáveis estudadas com o nível de satisfação do usuário, analisado pelo IOI-HA, por meio do fator 1 (que reflete a interação do indivíduo com seu AAS), o fator 2 (relacionado à interação do indivíduo com outras pessoas no seu ambiente) e a pontuação total de cada indivíduo. RESULTADOS: não houve correlação significante entre as variáveis estudadas e o nível de satisfação do usuário. Entretanto, é importante ressaltar que as médias obtidas nas análises, por item, foram positivas e, consequentemente, as análises da soma total do IOI-HA, fator 1 e fator 2, também foram positivas e se aproximaram dos escores máximos para cada fator. CONCLUSÃO: o presente estudo constatou que, no grupo estudado, os usuários de AAS estavam satisfeitos com a adaptação de seus aparelhos e não foram observadas correlações entre as variáveis estudadas e o grau de satisfação do usuário de AAS, por meio do questionário IOI-HA.

PURPOSE: assess satisfaction with hearing aids (HA) by applying the self-assessment questionnaire IOI-HA (International Outcome Inventory for Hearing Aids) and to correlate the characteristics of hearing loss and HA fitting process. METHOD: 98 patients from a healthy public service were assessed, of both genders, with sensorineural hearing loss, and using the HA in a systematic way for at least 3 months. The IOI-HA questionnaire was used as a guide directed structured interview with the patient. Correlated these variables with the level of user satisfaction analyzed by IOI-HA by a factor (which reflects the interaction of the patient with his HA), the second factor (related to the patient's experience with other people in their environment), and the total score for each patient. RESULTS: there was no significant correlation between these variables and user satisfaction. However, it is important to note that the averages obtained were positive and therefore the analyzes of the total sum of the IOI-HA, Factors 1 and 2, were also positive and approached the maximum score for each factor. CONCLUSION: this study found that in the studied group of HA users were satisfied with the adaptation of their HA and there were no correlations between variables and the degree of satisfaction with HA through the IOI-HA questionnaire.
