ABSTRACT

Abstract The present study was taken to test the hypothesis that the medial nucleus of the trapezoid body (MNTB) of echolocating neotropical bats with different foraging behavior will exhibit morphological variations in relative size, degree of complexity and spatial distribution. The brains were collected from six male adult bats of each species: Noctilio leporinus (fish-eating), Phyllostomus hastatus (carnivorous/ omnivorous) and Carollia perspicillata (fruit-eating) and were double-embedded and transverse serial sections were cut and stained with cresyl fast violet. The results showed that the MNTB is well developed in all the bats in general and the mean length of the MNTB was 1160 ± 124 µm in N. leporinus, 400 ± 59 µm in P. hastatus and 320 ± 25µm in C. perspicillata. The body and brain weight do not reflect proportionately on the size of the MNTB in the present study. The hearing frequency spectrum did not covary with the size of the MNTB among the bats studied. The MNTB is clearly demarcated from the ventral nucleus of the trapezoid body (VNTB) only in P. hastatus. The MNTB comprised mainly three types of cells in all three bats: dense-staining multipolar cells (12.5 µm and 25.0 µm diameter); light-staining multipolar cells measuring (12.5 µm and 25.0 µm diameter) and light-staining round cells (5.0 µm diameter). The large sized MNTB was observed in N. leporinus, which suggests that it relies heavily on echolocation whereas P. hastatus and C. perspicillata use echolocation as well but also rely on hearing, smell and vision.


Resumo O presente estudo foi realizado para testar a hipótese de que o núcleo medial do corpo trapezoide (MNTB) de morcegos neotropicais ecolocativos com comportamento forrageiro diferente apresenta variações morfológicas no tamanho relativo, grau de complexidade e distribuição espacial. Os cérebros foram coletados de seis morcegos machos adultos de cada espécie, Noctilio leporinus (comedor de peixe), Phyllostomus hastatus (carnívoro/onívoro) e Carollia perspicillata (comedor de frutas), e foram seccionados em série e seções seriais transversais duplas e coradas com cresil violeta. Os resultados mostraram que o MNTB é bem desenvolvido em todos os morcegos em geral e que o comprimento médio do MNTB foi de 1.160 ± 124 µm em N. leporinus, 400 ± 59 µm em P. hastatus e 320 ± 25 µm em C. perspicillata. O peso corporal e cerebral não reflete proporcionalmente o tamanho do MNTB no presente estudo. O espectro da frequência auditiva não covaria com o tamanho do MNTB entre os morcegos estudados. O MNTB é claramente demarcado do núcleo ventral do corpo trapezoidal (VNTB) apenas em P. hastatus. O MNTB compreendia principalmente três tipos de células nos três morcegos: células multipolares de coloração densa (12,5 µm e 25,0 µm de diâmetro), células multipolares de coloração clara (12,5 µm e 25,0 µm de diâmetro) e células redondas manchadas de luz (5,0 µm de diâmetro). O MNTB de grande porte foi observado em N. leporinus, o que sugere que ele depende muito da ecolocalização, enquanto P. hastatus e C. perspicillata também usam a ecolocalização, mas dependem da audição, olfato e visão.

ABSTRACT

El estudio tuvo como objetivo comparar el perfil neurocognitivo pacientes pediátricos normo-yentes de edades entre 3 a 6 años, con respecto al de niños en ese mismo grupo etario que presen-tan discapacidad auditiva, los que utilizaban un implante coclear por entre 24 a 36 meses. Para alcanzarlo, se hizo una investigación con diseño no experimental de tipo comparativo y enfoque cuantitativo. Los datos se obtuvieron a partir de los informes neuropsicológicos archivados en las historias clínicas de 10 pacientes preescolares, atendidos en el Centro de Rehabilitación Integral Especializada "CRIE" en la ciudad de Cuenca en 2019, los que se dividieron en dos grupos (uno con los discapacitados auditivos y otros sin esa característica). El instrumento aplicado en esa institución fue el Cuestionario de Madurez Neuropsicológica (CUMANIN). Las diferencias entre los dos grupos resultaron estadísticamente significativas en la mayoría de las escalas valoradas, los niños sin discapacidad auditiva mostraron un desarrollo neurocognitivo superior al resto de los participantes. La correlación entre las dimensiones del desarrollo neurocognitivo: lenguaje expresivo y fluidez verbal, con respecto a la edad en los niños con discapacidad auditiva, cuyas cifras fueron negativas y se enmarcan en la categoría de fuerte o absoluta


The objective of the study was to compare the neurocognitive profile of normally hearing pediatric patients aged 3 to 6 years with that of children in the same age group with hearing impairment, those who used a cochlear implant for 24 to 36 months. To achieve this, a research was carried out with a non-experimental design of a comparative type and a quantitative approach. The data were obtained from the neuropsychological reports filed in the medical records of 10 preschool patients, treated at the Centro de Rehabilitación Integral Especializada "CRIE" in the city of Cuenca in 2019. The population were divided into two groups (one with the hearing impaired and others without that feature). The instrument applied in that institution was the Neuropsychological Maturity Questionnaire. The differences between the two groups were statisti-cally significant in most of the scales evaluated, the children without hearing impairment showed a neurocognitive development superior to the rest of the participants. The correlation between the dimensions of neurocognitive development: expressive language and verbal fluen-cy, with respect to age in children with hearing disabilities, whose figures were negative and fall into the category of strong or absolute

ABSTRACT

La presente investigación se propuso determinar las pruebas de evaluación neuropsicológica más eficaces para niños con discapacidad auditiva mediante la revisión sistemática de la eviden-cia científica publicada. El proceso de búsqueda se hizo de mayo a septiembre de 2020, a partir de las bases de datos: Redalyc, Scielo, Ebsco, Hinari y Scopus. Los artículos seleccionados tenían hasta 10 años de publicación, escritos en idioma inglés. La información sistematizada en la bibliografía posibilitó determinar las pruebas confiables de la evaluación del desarrollo neuropsicológico en pacientes pediátricos con discapacidad auditiva: vocabulario (Test de Voca-bulario en Imágenes Peabody), lenguaje (Test de Evaluación Clínica de los Fundamentos del Lenguaje), funcionamiento ejecutivo (Behavioral Rating Inventory of Executive Function y las Pruebas de habilidades cognitivas Woodcock Johnson), inteligencia (Prueba Breve de Inteligencia de Kaufman). Mientras que, la Prueba informatizada AWARD, el Test de Vocabulario de Boston y el de habilidades de reconocimiento de oraciones (HINT) fueron valoradas con menor operatividad.


This research aimed to determine the most effective neuropsychological assessment tests for children with hearing impairment through a systematic review from published scientific eviden-ce. The searching process was carried out from May to September 2020, including the databa-ses: Redalyc, SciELO, Ebsco, Hinari and Scopus. The selected articles had up to 10 years of publication, written in English languages. The information systematized in the bibliography made it possible to determine the reliable tests of the neuropsychological development evalua-tion in pedagogical patients with hearing disabilities: vocabulary (Peabody Imaging Vocabulary Test), language (Clinical Evaluation of the Fundamentals of Language test), executive functio-ning (Behavioral Rating Inventory of Executive Function and the Woodcock Johnson Cognitive Ability Tests), intelligence (Kaufman Brief Intelligence Test). On the other hand, the AWARD computerized test, the Boston Vocabulary Test and the Sentence Recognition Skills Test (HINT) were evaluated with lower operability.

La revisión bibliográfica permitió valorar los aciertos y dificultades de otros procedimientos establecidos en otros contextos. Resultados: Se obtuvo como resultado el procedimiento para el pesquisaje auditivo universal, estructurado en tres componentes: pesquisaje, diagnóstico y rehabilitación. Conclusiones: El procedimiento diseñado para la detección universal precoz neonatal de las pérdidas auditivas en la población neonatal cubana estandariza los procesos de prestación de servicios de salud, mediante la gestión integral para prevenir y controlar, en forma oportuna, los eventos que afectan la salud auditiva(AU)


Introduction: Neonatal hearing screening is one of the most widely used techniques for early and timely diagnosis of hearing losses that lead to disability. Objective: To design the procedure for universal hearing screening in the Cuban neonatal population. Methods: Technological development study carried out from January to December 2017. Experts were selected through self-evaluation and the Kappa competence coefficient. The experts participated in the design through the nominal groups technique, in view of the analysis of the problems limiting universal hearing screening and the scientific, organizational and functional potentialities of the healthcare network for hearing disorders. Subsequently, they assessed the procedure individually and the nominal groups technique was applied to achieve consensus. The bibliographic review allowed to assess the accomplishments and difficulties of other procedures established in other settings. Results: The procedure for universal hearing screening was obtained as a result, structured in three components: screening, diagnosis and rehabilitation. Conclusions: The procedure designed for universal early neonatal screening of hearing loss in the Cuban neonatal population standardizes the processes of providing healthcare, through comprehensive management to prevent and control, timely, events that affect hearing-related health(AU)

ABSTRACT

Resumo Não há estudos, de abrangência nacional, caracterizando a acessibilidade para pessoas com deficiência no momento do parto. O objetivo do estudo foi descrever a estrutura física de estabelecimentos hospitalares quanto à acessibilidade para gestantes e puérperas com deficiência motora (DM), visual (DV) ou auditiva (DA) no Brasil. Estudo ecológico, descritivo, realizado em todos os 606 estabelecimentos vinculados à Rede Cegonha (RC), que realizaram partos em 2015. Foram feitas análises descritivas e de distribuição espacial. Considerou-se acessibilidade motora quando o estabelecimento tivesse rampa com corrimão ou elevador, portas com dimensões para cadeira de rodas e banheiro acessível com barras; acessibilidade visual quando houvesse sinalização tátil (sistema Braille ou figuras em relevo); e acessibilidade auditiva quando houvesse sinalização por textos, figuras, placas, cartazes ou símbolos nos ambientes. No Brasil, apenas 26 (4,3%) estabelecimentos tinham acessibilidade para pessoas com DM, 20 (3,3%) para pessoas com DA e nenhum para pessoas com DV. A acessibilidade motora foi pior no Norte e Nordeste e a auditiva, no Norte. Apesar dos avanços decorrentes da implantação da RC no Brasil, a estrutura dos estabelecimentos hospitalares não está adaptada para pessoas com DM, DV ou DA.


Abstract There are no nationwide studies characterizing accessibility for people with disabilities during delivery. This study aimed to describe the physical structure of hospital units regarding accessibility for pregnant and puerperae with motor (MD), visual (VD), or hearing (HD) disabilities in Brazil. This is an ecological, descriptive study conducted in all 606 health facilities linked to the "Rede Cegonha" where deliveries occurred, according to 2015 databases. We performed the descriptive and geospatial analysis and considered the presence of motor accessibility when the establishment had a handrail or elevator ramp, wheelchair-sized doors, and accessible bathroom with bars. We assumed visual accessibility when there was tactile signage on the floor (Braille system or embossed figures) and hearing accessibility when there was signage by texts, pictures, signs, posters, or symbols in the environments. In Brazil, only 26 (4.3%) of the facilities had accessibility for people with MD, 20 (3.3%) for people with VD, and none for HD. Motor accessibility was worse in the North and Northeast of Brazil, and hearing accessibility in the North region. Despite advances in the implementation of the "Rede Cegonha" in Brazil, the facilities' structure is not adapted for women with MD, VD, or HD.

ABSTRACT

Introducción: La audiometría de altas frecuencias (9000-20 000 Hz) puede ser de gran utilidad en el diagnóstico precoz de hipoacusia inducida por ruidos en contraste con la audiometría convencional (125-8000 Hz). Objetivo: Evaluar la utilidad de la audiometría de altas frecuencias en el diagnóstico precoz de la hipoacusia inducida por ruidos en adolescentes. Métodos: Estudio descriptivo, observacional y transversal en 85 adolescentes expuestos a ruidos; 45 cursaban el décimo grado en un preuniversitario de la provincia La Habana, en el curso escolar 2013-2014 y 40, el primer año de la carrera de medicina, en una facultad de La Habana en el curso escolar 2015- 2016. A todos se le realizó una encuesta, examen físico de otorrinolaringología, audiometría convencional y audiometría de alta frecuencia. Resultados: La audiometría convencional fue normal en todos los casos. En la audiometría de altas frecuencias en todos los adolescentes estudiados comenzó a disminuir la audición a partir de los 13 000 Hz y se apreció una hipoacusia neurosensorial en aumento hasta 85 decibeles en oído derecho y 78 decibeles en oído izquierdo en 20 000 Hz de frecuencia. Conclusiones: Los adolescentes evaluados tienen hábitos auditivos que pueden perjudicar su audición, todos ya poseen signos de daño que no se manifiestan a través de la audiometría convencional pero sí a través de la audiometría de alta frecuencia en las diferentes exposiciones a ruidos de altos decibeles. Lo anterior demuestra la utilidad de esta audiometría, no solo dentro del campo de la audiología, sino también en la medicina preventiva(AU)


Introduction: High frequency audiometry (9000-20 000 Hz) can be really useful in the early diagnosis of deafness induced by noises, in contrast with conventional tonal audiometry (125-8000 Hz). Objective: Assess the usefulness of high frequency audiometry in the early diagnosis of deafness induced by noises in adolescents. Methods: Descriptive, observational and cross-sectional study in 85 adolescents exposed to noises; 45 of them were studying the 10th grade in a high school of Havana province, and 40 of them were in the first year of Medicine in a faculty of Havana province during school year 2015-2016. All of them took a survey, a physical examination of otolaryngology, liminar total audiometry and high frequency audiometry. Results: Tonal audiometry was normal in all the cases. In high frequency audiometry of all the studied adolescents started to decrease audition from 13000 HZ and it was noticed an increasing neurosensorial deafness up to 85 decibels in the right ear and 78 decibels in the left ear in 20 000 Hz of frequency. Conclusions: The adolescents assessed have auditive habits that can jeopardize their audition; all of them already have signs of damage that are not noticed in the tonal audiometry but in the high frequency audiometry in the different exposures to noises of high decibels. This proves the usefulness of this kind of audiometry not only in the field of audiology, but also in preventive medicine(AU)

ABSTRACT

O presente estudo avaliou o efeito de determinantes contextuais e individuais da utilização da triagem auditiva neonatal no Distrito Federal e capitais brasileiras. O modelo teórico conceitual proposto por Andersen & Davidson (2014) orientou as análises mediante modelagem logística multinível, com dados da Pesquisa Nacional de Saúde, 2013. A população observada (n = 585) é representativa de 230.112 duplas de mulheres/responsáveis acima de 18 anos e respectivas crianças menores de 2 anos de idade. No nível contextual (Distrito Federal e capitais), a utilização da triagem auditiva neonatal foi determinada pela proporção de indivíduos extremamente pobres (razão de chances - RC = 0,91; intervalo de 95% de confiança - IC95%: 0,83-0,99) e pela cobertura mensal da triagem auditiva neonatal (RC = 1,02; IC95%: 1,01-1,02). No nível individual, verificou-se maior uso de triagem auditiva neonatal na faixa etária entre 25 e 39 anos, em comparação às < 25 anos. A chance de utilização de triagem auditiva neonatal foi menor em respondentes com raça/cor da pele parda (RC = 0,47; IC95%: 0,26-0,83) em comparação com brancas. Quanto à escolaridade, verificou-se que possuir Ensino Superior completo quase triplicou a chance de uso de triagem auditiva neonatal, em contraste com Ensino Fundamental de estudo formal (RC = 2,99; IC95%: 1,15-7,79). O pré-natal predominantemente privado aumentou em 2,18 vezes a chance de utilizar a triagem auditiva neonatal , em comparação ao público (RC = 2,18; IC95%: 1,02-4,64). A aplicação efetiva de leis e políticas de saúde auditiva já existentes e a priorização de práticas de atenção básica e educação em saúde com foco em neonatos em maior vulnerabilidade, conforme as características identificadas nesse estudo, são iniciativas para ensejar um sistema de proteção social equânime.


The current study assessed the effect of contextual and individual determinants of the use of newborn hearing screening in Brazilian state capitals and the Federal District. The conceptual theoretical model proposed by Andersen & Davidson (2014) oriented the analyses using multilevel logistic modeling with data from the Brazilian National Health Survey, 2013. The study population (n = 585) is representative of 230,112 pairs of women/responsible person over 18 years of age and their respective children under 2 years of age. At the contextual level (state capitals and Federal District), the use of newborn hearing screening was determined by the proportion of extremely poor individuals (odds ratio - OR = 0.91; 95% confidence interval - 95%CI: 0.83-0.99) and by monthly coverage of newborn hearing screening (OR = 1.02; 95%CI: 1.01-1.02). At the individual level, use of newborn hearing screening was higher in the maternal age bracket 25 to 39 years, compared to < 25 years. The odds of use of newborn hearing screening were lower in mothers with brown race/color (OR = 0.47; 95%CI: 0.26-0.83) compared to white mothers. As for schooling, complete university education nearly tripled the odds of newborn hearing screening when compared to primary schooling (OR = 2.99; 95%CI: 1.15-7.79). Predominantly private prenatal care increased the odds of using newborn hearing screening by 2.18 times, compared to public prenatal care (OR = 2.18; 95%CI: 1.02-4.64). Effective enforcement of existing hearing health laws and policies and prioritization of primary healthcare and health education practices with a focus on more vulnerable newborns, based on the characteristics identified in this study, are initiatives that can help ensure an equitable social protection system.

En el nivel individual, se verificó un mayor uso de tamizaje auditivo neonatal en la franja etaria entre 25 a 39 años, en comparación con las de < 25 años. La oportunidad de utilización de tamizaje auditivo neonatal fue menor en informantes con raza/color de la piel parda (OR = 0,47; IC95%: 0,26-0,83), en comparación con las blancas. Respecto a la escolaridad, se verificó que posee un Nivel Superior completo casi triplicó la oportunidad de uso de tamizaje auditivo neonatal, en contraste con el Nivel Fundamental de estudio formal (OR = 2,99; IC95%: 1,15-7,79). El prenatal, predominantemente privado, aumentó en 2,18 veces la oportunidad de utilizar el tamizaje auditivo neonatal, en comparación con el público (OR = 2,18; IC95%: 1,02-4,64). La aplicación efectiva de leyes y políticas de salud auditiva ya existentes, y la priorización de prácticas de atención básica y educación en salud, centrándose en neonatos de mayor vulnerabilidad, conforme las características identificadas en ese estudio, son iniciativas para exhibir un sistema de protección social ecuánime.

ABSTRACT

El labio fisurado se define como una anomalía congénita de la cabeza y el cuello, observándose una mayor incidencia en personas del sexo masculino. El tratamiento por excelencia es la intervención quirúrgica, en la búsqueda de una adecuada funcionalidad y un buen resultado estético, para cumplir con este objetivo es necesario el trabajo interprofesional, en el cual participa el fonoaudiólogo, durante el proceso de evaluación e intervención terapéutica. El objetivo de la revisión narrativa fue abordar principalmente los procesos de evaluación e intervención fonoaudiológica en niños con labio fisurado. Para su desarrollo fue realizada una búsqueda de información en las bases de datos PubMed, Scopus y Lilacs, posteriormente fue realizado un análisis crítico de la información. En la presente revisión narrativa se proponen realizar un recuento sobre aspectos relacionados con la historia de la clasificación del labio fisurado, factores etiológicos, procesos de intervención quirúrgica realizada en los niños con labio fisurado, que permitan comprender el proceso de la evaluación clínica fonoaudiológica en las áreas de deglución, lenguaje, habla, voz y las propuestas de intervención terapéutica en niños con labio fisurado de acuerdo con las evidencias presentadas en la literatura.


Cleft lip is defined as a congenital anomaly of head and neck, with a higher incidence in males. The treatment par excellence is surgical intervention seeking to achieve functionality and the best aesthetic result) for this the interprofessional work is necessary, in which the speech pathologist participates on the evaluation process and therapeutic intervention in swallowing, speech and language. The objective of this narrative review was to primarily address the processes of evaluation and speech therapy intervention in children with cleft lip. For its development, a search of information in PubMed, Scopus and Lilacs databases, subsequently a critical analysis of the information was made. This narrative review proposed to make a synthesis of the history, the etiological factors and the surgical intervention processes that are performed in children with cleft lip, this allows to understand the actions and importance of the speech pathologist's work in the processes of evaluation with specific protocols that involve all areas; swallowing, language, speech, voice, hearing and speech pathologist therapy intervention in children with cleft lip, based on the evidence that allows to acknowledge positive results, being promising for this population the implementation of summer camps

ABSTRACT

La posturografía permite evaluar la integración de los tres sistemas sensoriales que intervienen en el control postural y del equilibrio: el vestibular, el visual y el somatosensorial (Ronda, 2002). La presente investigación describe y analiza los resultados de la posturografía en niños entre seis y once años con pérdida auditiva quienes no han compensado su edad auditiva con respecto a su edad cronológica. Fueron evaluados dos grupos: el grupo control conformado por 32 niños con sensibilidad auditiva periférica normal y el grupo de estudio, conformado por 16 niños con pérdida auditiva, quienes usan amplificación auditiva y asisten a la Fundación CINDA para terapia auditiva con el fin de cerrar el GAP existente entre su edad cronológica y su edad auditiva. En la evaluación audiológica se aplicó anamnesis, revisión de historia clínica, audiometría tonal para la verificación de la sensibilidad auditiva periférica y posturografía, con un equipo de la marca NeuroCom, se realizaron las siguientes pruebas: Integración sensorial en balance-modificado (CTSIB), límites de estabilidad (LOS) y distribución de peso (WHT). En los resultados se encontraron diferencias estadísticamente significativas entre los dos grupos de estudio para las tres pruebas en distintas variables. Como conclusión se pudo determinar que existen diferencias estadísticamente significativas entre el grupo control y el grupo de estudio. La intervención con terapia ocupacional influenció positivamente los resultados en la posturografía, sobre todo en el grupo de 10 a 11 años. Se observaron diferencias sucesivas en los tres grupos de edad, indicando un componente de neuromaduración.


Posturography allows evaluating the integration of the three sensory systems involved in postural and balance control: vestibular, visual and somatosensory (Ronda, 2002). This research describes and analyzes the results of posturography in children between six and eleven years old with hearing loss who have not compensated their hearing age with respect to their chronological age. Two groups were evaluated: the control group made up of 32 children with normal peripheral hearing sensitivity and the study group, made up of 16 children with hearing loss, who use hearing amplification and attend the CINDA Foundation for hearing therapy in order to close the hearing loss. GAP between your chronological age and your hearing age. In the audiological evaluation, anamnesis, review of clinical history, tonal audiometry were applied to verify peripheral hearing sensitivity and posturography, with a NeuroCom brand equipment, the following tests were performed: Modified-balance sensory integration (CTSIB), stability limits (LOS) and weight distribution (WHT). In the results, statistically significant differences were found between the two study groups for the three tests in different variables. In conclusion, it was possible to determine that there are statistically significant differences between the control group and the study group. The occupational therapy intervention positively influenced the results in posturography, especially in the 10 to 11-year-old group. Successive differences were observed in the three age groups, indicating a neuromaturation component.

ABSTRACT

RESUMO Objetivo Analisar a percepção da incapacidade auditiva, a audição e a cognição em idosos encaminhados para avaliação audiológica e verificar a existência de correlação entre a audição e as habilidades cognitivas. Método Estudo observacional e descritivo, realizado com 135 idosos. Os participantes realizaram a avaliação auditiva (Audiometria Tonal Limiar, Logoaudiometria, Imitanciometria) responderam a um inventário que avalia a percepção da incapacidade auditiva (questionário HHIE - Hearing Handicap Inventory for the Elderly) e foram submetidos a um rastreio cognitivo (teste Mini Exame do Estado Mental - MEEM). Resultados Houve elevada prevalência de queixa auditiva e perda da audição nos idosos encaminhados para avaliação auditiva, mas não houve relação do grau da perda auditiva e da percepção da incapacidade auditiva em relação ao desempenho cognitivo. Conclusão Neste estudo, o grau da perda auditiva não influenciou o desempenho cognitivo dos idosos, e a percepção da incapacidade auditiva não diferiu entre indivíduos com cognição normal ou alterada.


ABSTRACT Purpose To analyze auditory perception, hearing and cognition in the elderly referred for audiological evaluation and search for correlations between hearing and cognitive abilities. Method An observational and descriptive study, carried out with 135 elderly people. The participants did the auditory (tonal audiometry, speech audiometry, immittance measures, HHIE Questionnaire - Hearing Handicap Inventory for the Elderly) and the cognitive (MMSE - Mini Mental State Examination) assessments. Results There is a high prevalence of hearing complaints (91.85%) and hearing loss (91.85%) in the elderly referred for audiological assessment, but there was no relation between the degree of hearing loss (p = 0.537) and the auditory perception (p = 0.930) in relation to cognitive performance. Conclusion In this study, the degree of hearing loss did not influence the cognitive performance of the elderly, and the auditory handicap perception did not differ between individuals with normal or altered cognition.

ABSTRACT

RESUMO Objetivo Avaliar a acurácia de instrumentos de custo acessível para triagem auditiva de adultos e idosos. Método Este estudo foi realizado com usuários de um Serviço de Saúde Auditiva do SUS. Todos foram submetidos a triagem com o aplicativo de smartphone MoBASA, o audiômetro Telessaúde (TS) e a versão eletrônica do Questionário de Handicap da Audição para Idosos (Hearing Handicap Inventory for the Elderly - screening version - eHHIE-S). Os examinadores foram cegos quanto aos resultados dos testes de triagem e para os dados de audiometria de tom puro (ATP). Foram considerados com deficiência auditiva aqueles com média quadritonal na ATP maiores que 40 dB na melhor orelha. Sensibilidade, especificidade e valores preditivos positivo (VPP) e negativo (VPN) foram calculados. O índice Kappa foi usado como um indicador de concordância entre ATP e os resultados da triagem. Resultados A amostra constou de 80 indivíduos entre 18 a 94 anos (55,18 ± 20,21). Na ATP, 21 indivíduos (26,25%) apresentaram audição normal e 59 (73,75%) perda auditiva incapacitante. Nos testes de triagem auditiva observou-se valores de sensibilidade, especificidade, VPP e VPN maiores do que 75% no MoBASA e na sensibilidade e VPN do TS e eHHIE-S. Já a especificidade e VPP do TS e eHHIE-S foram inferiores a 75%. O índice Kappa indicou concordância substancial (0,6) entre o ATP e os resultados do MoBASA. No TS e eHHIE-S foi constatada regular concordância (0,3). Conclusão O MoBASA demonstrou ser um método acurado para triagem auditiva de adultos e idosos com perda auditiva incapacitante.


ABSTRACT Purpose To evaluate the accuracy of affordable instruments for hearing screening of adults and the elderly. Methods This study was carried out with users of a Hearing Health Service of the Unified Health System. All were screened with the MoBASA smartphone application, the Telehealth audiometer (TH) and the electronic version of the Hearing Handicap Inventory for the Elderly - screening version - eHHIE-S. The examiners were blinded to the results of the screening tests and pure tone audiometry (PTA). Hearing impairment was considered for those with a PTA quadritonal mean greater than 40 dB in the best ear. Sensitivity, specificity and positive and negative predictive values (PPV and NPV, respectively) were calculated. The Kappa index was used as an agreement indicator between the PTA and the screening results. Results The sample consisted of 80 individuals between 18 and 94 years old (55.18 ± 20.21). In the PTA test, 21 individuals (26.25%) had typical hearing and 59 (73.75%) hearing loss. In the hearing screening tests, sensitivity, specificity, PPV and NPV values greater than 75% were observed with the MoBASA as well as in terms of sensitivity and NPV of the TH and the eHHIE-S. The TH and the eHHIE-S specificity and PPV were less than 75%. The Kappa index indicated a substantial agreement (0.6) between the PTA and the MoBASA screening results. The TH and the eHHIE-S showed regular agreement (0.3). Conclusion MoBASA proved to be an accurate method for hearing screening of adults and the elderly with disabling hearing loss.

ABSTRACT

RESUMO Objetivo verificar a aplicabilidade do THS em mensurar e diferenciar as queixas de zumbido, perda auditiva e tolerância ao som. Método Foi aplicado o questionário THS, composto por 4 questões sobre zumbido, 4 sobre perda auditiva e 1 sobre tolerância ao som. Previamente, todos os participantes realizaram uma bateria de exames de diagnóstico audiológico e foram divididos em grupos: audição normal bilateral com média até 25dB, com e sem queixa de zumbido (Grupos 1 e 3); diagnóstico de perda auditiva sensório neural de grau leve a moderado (26dB a 60dB), sem uso prévio de aparelho de amplificação sonora Individual (AASI), com queixa de zumbido crônico (≥6 meses) e também indivíduos sem queixa de zumbido (Grupos 2 e 4); idade igual ou superior a 18 anos. Resultados Foram incluídos no presente estudo 70 indivíduos. Em relação a análise do total entre os grupos pelo teste Kruskal-Wallis foram encontradas diferenças significativas nas seções sobre zumbido e perda auditiva, mas não houve significância da seção sobre tolerância ao som. Em relação às questões sobre zumbido apenas os grupos 3 e 4 pontuaram. Quanto às questões referentes à perda auditiva, os grupos sem perda (grupos 1 e 3) foram os que menos pontuaram. Em relação a questão do THS sobre tolerância ao som, o grupo 3 foi o que mais pontuou. Conclusão o questionário THS se mostrou como uma possível ferramenta para auxiliar na compreensão e diferenciação das queixas auditivas.


ABSTRACT Purpose To verify the applicability of the Tinnitus and Hearing Survey (THS) to measure the different complaints of tinnitus, hearing loss and sound tolerance. Methods THS was performed, composed of 4 questions about tinnitus, 4 about hearing loss and one about sound tolerance. Previously, all participants performed a battery of audiological diagnostic tests and were then divided into 4 groups: Bilateral normal audiometry with mean up to 25dB, with and without tinnitus complaint (Groups 1 and 3); diagnosis of mild to moderate neural sensory hearing loss (26dB to 60dB), no previous use of individual hearing aids, complaining of chronic tinnitus (≥6 months) and individuals without tinnitus complaints (Groups 2 and 4); and age ≥18 years old. Results Seventy subjects were included in the present study. Regarding the analysis of the total between the groups by the Kruskal-Wallis test, significant differences were found in the sections about tinnitus and hearing loss, but there was no significance in the section regarding sound tolerance. Regarding the questions in Section A of the THS, only Groups 3 and 4 scored the highest. Regarding the questions related to Section B about hearing loss, the groups without hearing loss (Groups 1 and 3) scored the lowest. In relation to the question of the THS in Section C, Group 3 scored the highest. Conclusions The THS questionnaire proved to be a useful, quick and simple tool to assist the audiologist in the understanding and differentiation of the audiologic complaints.

ABSTRACT

RESUMO Objetivo foi verificar o grau de confiabilidade do Speech, Spatial and Qualities of Hearing Scale (SSQ), na avaliação do benefício em usuários de próteses auditivas. Método Participaram do estudo 30 adultos deficientes auditivos, candidatos ao uso (novatos) ou usuários em fase de troca de suas próteses auditivas (experientes). Todos os participantes realizaram avaliação audiológica completa, seleção e adaptação das próteses auditivas que incluiu a verificação com medidas com microfone sonda e avaliação do benefício do uso das próteses auditivas utilizando o questionário Speech, Spatial and Qualities of Hearing Scale (SSQ). Inicialmente, foi aplicado o questionário SSQ Base, em forma de entrevista. Após quatro semanas de uso das próteses auditivas novas reaplicou-se o questionário SSQ, em sua versão B (para os novatos) e C (para os experientes). Resultados Foi identificada maior dificuldade no domínio Audição para fala, do que nos outros domínios Audição espacial e Qualidades da audição. Todas as questões foram de fácil compreensão para a maioria dos participantes, que relataram serem compatíveis com as situações do seu cotidiano. A análise estatística revelou alto coeficiente Alpha de Cronbach (>0,9), demonstrando boa consistência interna entre os diversos itens do questionário. Demonstrou ser uma valiosa ferramenta para avaliar subjetivamente o desempenho comunicativo com e sem próteses auditivas. Conclusão O SSQ mostrou ser um instrumento de fácil aplicação e com alta confiabilidade que permite avaliação do benefício em indivíduos que se encontram em processo de reabilitação auditiva e pode ser aplicado a indivíduos que utilizam diferentes tipos de próteses auditivas.


ABSTRACT Purpose To check the degree of reliability of the Speech, Spatial and Qualities of Hearing Scale (SSQ), in the assessment of the benefit in hearing aid users. Methods Thirty hearing impaired adults, candidates for use (novice users) or users whose hearing aids (experienced users) were being replaced, participated in the study. All participants underwent complete audiological evaluation, selection and fitting of hearing aids, which included checking measurements with a probe microphone and assessment of the benefit from using hearing aids with the Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire. A basic SSQ questionnaire was administered in the form of an interview. Later, four weeks after having started using new hearing aids, the versions B (for novice users) and C (for experienced users) of the SSQ questionnaire were administered. Results Greater difficulty was identified in the Hearing for speech domain than in the other domains, namely Spatial hearing, and Qualities of hearing. Most participants found all questions easy to understand and reported they were compatible with the situations they dealt with in their daily life. Statistical analysis revealed a high Cronbach's alpha coefficient (>0.9), which is indicative of good internal consistency between the various items contained in the questionnaire. It proved to be a valuable tool for subjectively assessing communicative performance with and without the use of hearing aids. Conclusion The SSQ proved to be an instrument that is easy to administer and highly reliable, allowing for the assessment of the benefit in individuals who are undergoing auditory rehabilitation, and which can be administered to individuals using different types of hearing aids.

ABSTRACT

RESUMO Objetivo Avaliar como as vias auditivas codificam e diferenciam as sílabas plosivas [ga],[da] e [ba], por meio do potencial evocado auditivo Frequency Following Response (FFR), nas crianças em desenvolvimento típico. Método Vinte crianças (6-12 anos) foram avaliadas por meio do FFR para estímulos [ga],[da] e [ba]. Os estímulos foram compostos por seis formantes, sendo diferenciados na transição F2 e F3 (porção transiente). Os demais formantes foram idênticos nas três sílabas (porção sustentada). Foram analisadas latências de 16 ondas que compõe a porção transiente do estímulo (<70ms) e latências de 21 ondas da porção sustentada (90-160ms) nas respostas neurais obtidas para cada uma das sílabas. Resultados As respostas eletrofisiológicas registradas por meio do FFR demonstraram que as latências da porção transiente da resposta neural foram diferentes nas três silabas evocadas. Além disso, os valores de latência das ondas da porção transiente foram aumentando progressivamente, sendo [ga]<[da]<[ba]. Já na porção sustentada da resposta, não houve diferenças significantes nas latências das ondas que compõe essa porção. Conclusão O FFR mostrou-se uma ferramenta eficiente na investigação da discriminação subcortical de diferenças acústicas dos sons de fala, uma vez que demonstrou diferentes resposta eletrofisiológica para três silabas evocadas. Na porção transiente (consoantes) foram observadas mudanças de latência e na porção sustentada (vogal) não houve diferenças entre as latências para os três estímulos. Esses resultados demonstram a capacidade neural de distinção entre características acústicas dos estímulos [ga],[da],[ba].


ABSTRACT Purpose To evaluate how the auditory pathways encode and discriminate the plosive syllables [ga], [da] and [ba] using the auditory evoked Frequency-following Response (FFR) in children with typical development. Methods Twenty children aged 6-12 years were evaluated using the FFR for the [ga], [da] and [ba] stimuli. The stimuli were composed of six formants and were differentiated in the F2 to F3 transition (transient portion). The other formants were identical in the three syllables (sustained portion). The latencies of the 16 waves of the transient portion (<70ms) and of the 21 waves of the sustained portion (90-160ms) of the stimuli were analyzed in the neural responses obtained for each of the syllables. Results The transient portion latencies were different in the three syllables, indicating a distinction in the acoustic characteristics of these syllables through their neural representations. In addition, the transient portion latencies progressively increased in the following order: [ga] <[da] <[ba], whereas no significant differences were observed in the sustained portion. Conclusion The FFR proved to be an efficient tool to investigate the subcortical acoustic differences in speech sounds, since it demonstrated different electrophysiological responses for the three evoked syllables. Changes in latency were observed in the transient portion (consonants) but not in the sustained portion (vowels) for the three stimuli. These results indicate the neural ability to distinguish between acoustic characteristics of the [ga], [da] and [ba] stimuli.

ABSTRACT

@#Objective. The purpose of this study is to identify the incidence rate of 'refer' result in neonates born to diabetic mothers and to determine the association of maternal diabetes and the initial 'refer' result. Methods. This was a retrospective cross-sectional study which included neonates who had hearing screening test using transient-evoked otoacoustic emissions test (TEOAE) on both ears at the Philippine General Hospital Ear unit during three weeks. We obtained the demographic characteristics, presence/absence of maternal diabetes, and OAE results. Results. Among the 150 neonates, ten were born to diabetic mothers, with an age range of 2-8 days old. Forty percent of neonates of diabetic mothers had an initial 'refer' result compared with 7.9% of nondiabetic mothers' neonates. After logistic regression analysis, there is a significant association between maternal diabetes and initial 'refer' result in OAE with a p-value <0.05. If the mother is diagnosed with diabetes (gestational/pre-gestational), the odds of having an initial 'refer' result in the hearing screening is 2x higher. The odds can range from 2-43 times. Conclusion. The incidence rate of an initial 'refer' result in neonates of diabetic mothers is 40%. There is a significant association between maternal diabetes and the initial 'refer' result in the OAE test.

ABSTRACT

OBJECTIVE@#To analyze the results of concurrent hearing and deafness genetic screening and follow up of newborns.@*METHODS@#In total 33 911 babies born to 5 designated hospitals in Nanshan District of Shenzhen city from October 2017 to December 2019 were included. All subjects underwent concurrent hearing and deafness genetic screening covering 21 variants of 4 genes including GJB2, SLC26A4, GJB3 and Mt12SrRNA. For those with positive results, Sanger sequencing was carried out for confirmation.@*RESULTS@#93.32% subjects passed the first-round hearing screening, and 87.01% passed the recheck testing. The overall detection rate was 4.18%. The detection rates for GJB2, SLC26A4, GJB3 and Mt12srRNA variants were 1.98%, 1.58%, 0.37% and 0.25%, respectively. 126 and 84 subjects were found with high risk for delayed-onset and drug-induced hearing loss, respectively. In addition, 4 and 5 subjects were found to harbor homozygous/compound heterozygous variants of the GJB2 and SLC26A4 genes, respectively. Concurrent screening showed that subjects (with heterozygous variants) who did not passed the two round hearing test were as follows: GJB2 with 6.75% in the first round and 2.61% in the second round testing, SLC26A4 (3.3%/1.2%), GJB3 (0.72%/0.14%) and 12SrRNA (0.36%/Nil), respectively. Moreover, the No-pass rate in the subjects with homozygous or compound variants in single gene, heterozygous variant in single gene, heterozygous variant in multiple genes, and homozygous variant in GJB3 gene were significantly higher than the subjects with negative results of genetic screening.@*CONCLUSION@#Concurrent newborn genetic screening can enhance the effectiveness of hearing screening and enable earlier identification and intervention for children with hearing impairment. Follow-up can improve the diagnostic rate for children who are positive for the concurrent screening. Nevertheless, genetic and hearing screening cannot replace the diagnostic testing. It is necessary to conduct comprehensive analysis for the results of genetic and hearing screening and radiological examinations. Sanger sequencing and next-generation sequencing are critical for ascertain the diagnosis.

ABSTRACT

Abstract Introduction: The study of the threshold level of cortical auditory response in adults has been investigated in previous studies. Due to maturational issues, little is known about these responses in neonates. Technological advances with automatic analysis devices now allow investigation in specific populations. Thus, new studies are needed to establish the feasibility of using this auditory potential to identify the lowest levels of responses in children. Objective: Verify and compare latency and amplitude in 80 dBnNA and the minimum level of cortical auditory response in term and preterm neonates. Methods: A cross-sectional, comparative study involving 59 neonates, 35 full-term births and 24 preterm births, with positive results in the Neonatal Hearing Screening. The Hearlab system was used to investigate the P1i auditory potential with tone burst stimulus at frequencies of 500, 1000, 2000 and 4000 Hz. The minimum response level search ranged from 80 to 0 dBNA and was detected automatically. The results were compared between groups, evaluating the latency and amplitude in 80 dBNA and the minimum level of cortical auditory response. Results: The mean values obtained for the minimum level of cortical auditory response in term group were 26 ± 8.81; 26.14 ± 6.97; 29 ± 7.65 and 29.43 ± 7.04 dBNA and for preterm neonates of 31.96 ± 10.41; 34.13 ± 11.34; 33.64 ± 11.03 and 37.73 ± 11.92 dBNA, for the frequencies of 500, 1000, 2000 and 4000 Hz, respectively. There was a difference between groups for the latency of P1i at 4000 Hz and the minimum response levels at 500, 1000 and 4000 Hz, with higher values for preterm infants. Conclusion: It was possible to obtain latency and amplitude values at 80 dBnNA and the minimum level of cortical response in term and preterm newborns, with different results between groups, with higher values in those born preterm.


Resumo Introdução: A investigação do nível mínimo de resposta auditiva cortical tem sido alvo de diferentes estudos em adultos. Devido a questões de maturação, pouco se sabe sobre essas respostas em recém-nascidos. Com o avanço tecnológico, dispositivos de análise automática surgiram com o objetivo de retomar essa avaliação em populações específicas. Assim, novos estudos são necessários para verificar a viabilidade do uso desse potencial auditivo na obtenção de níveis mínimos de respostas na criança. Objetivo: Verificar e comparar latência e amplitude em 80 dBnNA e o nível mínimo de resposta auditiva cortical em recém-nascidos a termo e pré-termo. Método: Estudo transversal, comparativo, envolvendo 59 neonatos, 35 nascidos a termo e 24 pré-termos, com resultados positivos na triagem auditiva neonatal. O sistema Hearlab foi utilizado para investigar o potencial auditivo P1i com estímulo tone burst nas frequências de 500, 1000, 2000 e 4000 Hz. A busca do nível mínimo de resposta variou de 80 a 0 dBNA e foi detectado automaticamente. Os resultados foram comparados entre os grupos, avaliando a latência e amplitude em 80 dBNA e o nível mínimo de resposta auditiva cortical. Resultados: Os valores médios obtidos para o nível mínimo de resposta auditiva cortical no grupo nascido a termo foram 26 ± 8,81; 26,14 ± 6,97; 29 ± 7,65 e 29,43 ± 7,04 dBNA e para recém-nascidos pré-termos foram de 31,96 ± 10,41; 34,13 ± 11,34; 33,64 ± 11,03 e 37,73 ± 11,92 dBNA, para as frequências de 500, 1000, 2000 e 4000 Hz, respectivamente. Houve diferenc¸a entre os grupos para a latência de P1i em 4000 Hz e os níveis mínimos de resposta em 500, 1000 e 4000 Hz, com valores maiores em Pré-termos. Conclusão: Foi possível obter valores de latência e amplitude em 80 dBnNA e o nível mínimo de resposta cortical em recém-nascidos a termo e Pré-termos, com resultados diferentes entre osgrupos, com valores maiores em pré-termos.

ABSTRACT

Abstract Introduction: Evidences of possible effects of early age otitis media with effusion in the central auditory processing, emphasize the need to consider such effects also in subjects with chronic otitis media. Aim: To investigate and analyze the impact of non-cholesteatomatous chronic otitis media on central auditory processing in teenagers. Methods: This is a study in which 68 teenagers were recruited, 34 with a diagnosis of non-cholesteatomatous chronic otitis media (study group) and 34 without otological disease history (control group). The evaluation of the subjects consisted of: anamnesis, pure-tone threshold audiometry, speech audiometry and a behavioral test battery for assessment of central auditory processing. Results: A statistically significant difference was found between the means observed in the study and control groups in all tests performed. An association was found between the control group and subgroups of the study group with unilateral alterations in all tests. An association was shown between the results for the control group and study group for family income, with a greater impact on subjects with a lower income. Conclusions: Non-cholesteatomatous chronic otitis media affects the central auditory processing in teenagers suffering from the disorder, and monaural low-redundancy hearing is the most affected auditory mechanism. Unilateral conductive changes cause more damage than bilateral ones, and lower family income seems to lead to more changes to the central auditory processing of subjects with non-cholesteatomatous chronic otitis media.


Resumo Introdução: As evidências de prováveis efeitos de otite média com efusão precoce no proces-samento auditivo central, ressaltam a necessidade de se considerar tais efeitos também em sujeitos com otite média crônica. Objetivo: Investigar e analisar o impacto da otite média crônica não colesteatomatosa no processamento auditivo central em adolescentes. Método: Estudo para o qual foram recrutados 68 adolescentes, 34 com diagnóstico de otite média crônica não colesteatomatosa (grupo de estudo) e 34 sem história otológica (grupo controle). A avaliação dos indivíduos consistiu de: anamnese, audiometria do limiar auditivo para tons puros, audiometria vocal e bateria de testes comportamentais para avaliação do processamento auditivo central. Resultados: Foi encontrada uma diferença estatisticamente significante entre as médias observadas nos grupos de estudo e controle em todos os testes. Foi encontrada uma associação entre o grupo controle e os subgrupos do grupo de estudo com alterações unilaterais em todos os testes. Houve associação entre os resultados dos grupos controle e de estudo para a renda familiar, com maior impacto nos indivíduos com menor renda. Conclusões: A otite média crônica não colesteatomatosa afeta o processamento auditivo central em adolescentes, a audição monoaural de baixa redundância é o mecanismo auditivo mais afetado. Alterações condutivas unilaterais causam mais danos do que as bilaterais e a menor renda familiar parece conduzir a mais alterações no processamento auditivo central de indivíduos com otite média crônica não colesteatomatosa.
