ABSTRACT

Introdução: A COVID-19 pode afetar o sistema auditivo, justificando a avaliação da audição de indivíduos infectados. Objetivo: analisar a via auditiva até o tronco encefálico de indivíduos acometidos por COVID-19 comparados ao grupo controle. Método: Estudo observacional transversal analítico realizado em uma amostra não probabilística de adultos que tiveram COVID-19, que foram comparados com um grupo controle, sem queixa auditiva. A avaliação consistiu em: medidas de imitância acústica, audiometria tonal liminar (ATL), emissões otoacústicas evocadas por estímulo transiente (EOET) e potencial evocado auditivo de tronco encefálico (PEATE). Resultados: Foram avaliados 77 indivíduos, sendo, 41 participantes do grupo COVID-19 (idade média de 26,3) e 36 do grupo controle (idade média de 25,8). Os limiares auditivos estavam dentro dos padrões da normalidade para todos os indivíduos do grupo COVID-19, sendo significativamente maiores para as frequências de 1000, 2000 e 3000 Hz à direita. A amplitude das EOET foi significativamente menor na banda de frequência de 1500 à direita. Houve correlação significativa e negativa para as frequências de 1000 Hz e 3000 Hz à direita e para as frequências de 1000, 2000 e 3000 Hz à esquerda, entre EOET e ATL. Foi verificado aumento da latência absoluta da onda I, do PEATE, na orelha esquerda. Conclusão: a COVID-19 afetou locais específicos do sistema auditivo. Houve diminuição da acuidade auditiva e do funcionamento das células ciliadas externas da cóclea, bem como aumento do tempo de condução neural do som na porção distal do VII par craniano à esquerda.

Introduction: COVID-19 can affect the auditory system, justifying the evaluation of the hearing of infected individuals. Objective: to analyze the auditory pathway to the brainstem of individuals affected by COVID-19 compared to the control group. Method: Analytical cross-sectional observational study carried out in a non-probabilistic sample of adults who had COVID-19, who were compared with a control group, without hearing complaints. The evaluation consisted of: acoustic immittance measurements, pure tone audiometry (PTA), transient stimulus-evoked otoacoustic emissions (TEOAE) and brainstem auditory evoked potential (BAEP). Results: 77 individuals were evaluated, 41 participants in the COVID-19 group (average age of 26.3) and 36 in the control group (average age of 25.8). Hearing thresholds were within normal limits for all individuals in the COVID-19 group, being significantly higher for the frequencies of 1000, 2000 and 3000 Hz on the right. TEOAE amplitude was significantly lower in the 1500 frequency band on the right. There was a significant and negative correlation for the frequencies of 1000 Hz and 3000 Hz on the right and for the frequencies of 1000, 2000 and 3000 Hz on the left, between TEOAE and PTA. An increase in the absolute latency of wave I, of the BAEP, was observed in the left ear. Conclusion: COVID-19 affected specific locations in the auditory system. There was a decrease in auditory acuity and the functioning of the outer hair cells of the cochlea, as well as an increase in the neural conduction time of sound in the distal portion of the VII cranial nerve on the left.

ABSTRACT

Noise is one of the most common environmental hazards to which people are exposed,and the exposure to noise can cause not only hearing but also non-hearing damage.Although noise under safety limits may not affect the auditory system,it can cause changes in stress hormone levels,which is harmful to health.However,the current studies about the impact of noise on health mainly focus on the auditory system,and little is known about the relationship between noise and stress hormone levels.Therefore,this paper reviews the studies involving noise exposure and stress hormone levels,aiming to provide ideas for strengthening the prevention and control of noise hazards.

ABSTRACT

Objective: To analyze the surgical efficacy of patients with mixed hearing loss and otosclerosis with different air bone gap (ABG) before surgery, and to provide reference for the prognosis evaluation of otosclerosis surgery. Methods: The clinical data of 108 cases(116 ears) of otosclerosis who had undergone stapes fenestration technique artificial stapes implantation in Xiangya Hospital of Central South University from November 2013 to May 2020 and had mixed hearing loss before surgery were collected, including 71 women(76 ears)and 37 men (40 ears), with an average age of 38.5 years. According to preoperative pure tone audiometry ABG, they were divided into three groups: group S, 15 dB≤ABG<31 dB, a total of 39 ears; group M, 31 dB≤ABG<46 dB, a total of 58 ears; and group L, ABG≥46 dB, 19 ears in total. The hearing outcomes of three groups of patients at 6-12 months after surgery were compared and analyzed using SPSS 24.0 statistical software. Results: A total of 3 patients (group S: 2 cases; group L: 1 case) experienced severe sensorineural hearing loss after surgery and were not included in the statistical analysis. After surgery, the pure tone hearing threshold of patients with otosclerosis in each group was significantly improved compared to before surgery, with an average air conduction threshold improvement of(21.6±13.4) dB. The difference between before and after surgery was statistically significant(t=17.13, P<0.01). The average bone conduction threshold improved by(3.7±7.6) dB, and the difference was statistically significant before and after surgery(t=5.20, P<0.01). The postoperative ABG was(18.3±9.3) dB, which was significantly reduced compared to preoperative(36.2±8.6)dB. Among the three groups of patients, the L group had the highest improvement in air conduction threshold[(29.9±10.8)dB], while the S group had the lowest improvement[(15.7±11.4)dB]. There was no statistically significant difference in post operative pure tone hearing thresholds between the three groups(P>0.05). The postoperative ABG in group S was the smallest[(16.5±9.0)dB], while in group L, the postoperative ABG was the largest[(20.5±10.0)dB]. Compared with group S, group M and group L still had a large residual ABG at 2 000 Hz after surgery. The bone conduction threshold of both S and M groups improved to some extent after surgery compared to before (P<0.01). Conclusions: Surgery can benefit patients with mixed hearing loss and otosclerosis with different preoperative ABG. Patients with small preoperative ABG have better surgical results and ideal ABG closure at all frequencies after surgery. Patients with large preoperative ABG can significantly increase the gas conduction threshold during surgery, but certain frequencies of ABG may still be left behind after surgery. The improvement effect of surgery on bone conduction threshold is not significant. Patients should be informed of treatment methods such as hearing aids based on their actual situation for selection.

ABSTRACT

Objective: To explore the value of electrically evoked auditory brainstem response (EABR) monitoring combined with brainstem auditory evoked potential (BAEP) and compound action potential (CAP) monitoring during vestibular schwannoma resection for the protection of the cochlear nerve. Methods: Clinical data from 12 patients with vestibular schwannomas who had useful hearing prior to surgery were analyzed at the PLA General Hospital from January to December 2021. Among them, there were 7 males and 5 females, ranging in age from 25 to 59 years. Before surgery, patients underwent audiology assessments (including pure tone audiometry, speech recognition rate, etc.), facial nerve function evaluation, and cranial MRI. They then underwent vestibular schwannoma resection via the retrosigmoid approach. EABR, BAEP, and CAP were simultaneously monitored during surgery, and patients' hearing preservation was observed and analyzed after surgery. Results: Prior to surgery, the average PTA threshold of the 12 patients ranged from11 to 49 dBHL, with a SDS of 80% to 100%. Six patients had grade A hearing, and six patients had grade B hearing. All 12 patients had House-Brackman grade I facial nerve function prior to surgery. The MRI indicated tumor diameters between 1.1 and 2.4 cm. Complete removal was achieved in 10/12 patients, while near-total removal was achieved in 2/12 patients. There were no serious complications at the one-month follow-up after surgery. At the three-month follow-up, all 12 patients had House-Brackman grade I or II facial nerve function. Under EABR with CAP and BAEP monitoring, successful preservation of the cochlear nerve was achieved in six of ten patients (2 with grade B hearing, 3 with grade C hearing, and 1 with grade D hearing). Successful preservation of the cochlear nerve was not achieved in another four patients (all with grade D hearing). In two patients, EABR monitoring was unsuccessful due to interference signals; however, Grade C or higher hearing was successfully preserved under BAEP and CAP monitoring. Conclusion: The application of EABR monitoring combined with BAEP and CAP monitoring during vestibular schwannoma resection can help improve postoperative preservation of the cochlear nerve and hearing.

ABSTRACT

Objective: To get insight into the current practice of noise reduction effect of workers as they wore hearing protectors in different domestic enterprises and the possible affected factors. Methods: From October 2020 to April 2021, using a random sampling method, 1197 workers exposed to noise in petrochemical factories, textile factories, and parts manufacturing factories were selected as the study subjects. The noise reduction effect of hearing protectors worn by workers in daily use was tested using a hearing protector suitability testing system. The personal sound attenuation level (PAR) was compared among workers in three enterprises, Targeted intervention and repetitive testing were conducted for workers who did not meet the noise reduction effect required by the enterprise, and the changes in PAR of workers before and after the intervention were compared. The comparison of baseline PARs between two or more groups was performed using the Mann Whitney test, the comparison of baseline PARs with post intervention PARs was performed using the Wilcoxon signed rank sum test, and the comparison of qualitative data between two or more groups was performed using the Chi square test. Results: The median baseline PAR for all workers was 15 dB. Men, age<30 years old, education level at or above college level, working experience of 5 to 15 years, and those who used hearing protectors for 5 to 15 years had higher PARs, with statistically significant differences (P<0.05). The median difference in baseline PAR among workers from three enterprises was statistically significant (H=175.06, P<0.01). The median PAR of subjects who did not pass the baseline increased from 3 dB to 21 dB after intervention (Z=-27.92, P<0.01) . Conclusion: Some workers wearing hearing protectors do not meet the required PAR, and low PARs may be related to incorrect wearing methods and incorrect selection of hearing protectors. As a tool for testing, training, and assisting in selection, the hearing protector suitability testing system is of great significance for worker hearing protection.

ABSTRACT

OBJECTIVE@#To analyze the clinical significance of combined newborn hearing and deafness gene screening in Yuncheng area of Shanxi Province.@*METHODS@#Results of audiological examinations, including transient evoked otoacoustic emission and automatic discriminative auditory brainstem evoked potentials, for 6 723 newborns born in Yuncheng area from January 1, 2021 to December 31, 2021, were retrospectively analyzed. Those who failed one of the tests were considered to have failed the examination. A deafness-related gene testing kit was used to detect 15 hot spot variants of common deafness-associated genes in China including GJB2, SLC26A4, GJB3, and mtDNA12S rRNA. Neonates who had passed the audiological examinations and those who had not were compared using a chi-square test.@*RESULTS@#Among the 6 723 neonates, 363 (5.40%) were found to carry variants. These have included 166 cases (2.47%) with GJB2 gene variants, 136 cases (2.03%) with SLC26A4 gene variants, 26 cases (0.39%) with mitochondrial 12S rRNA gene variants, and 33 cases (0.49%) with GJB3 gene variants. Among the 6 723 neonates, 267 had failed initial hearing screening, among which 244 had accepted a re-examination, for which 14 cases (5.73%) had failed again. This has yielded an approximate prevalence of hearing disorder of 0.21% (14/6 723). Among 230 newborns who had passed the re-examination, 10 (4.34%) were found to have carried a variant. By contrast, 4 out of the 14 neonates (28.57%) who had failed the re-examination had carried a variant, and there was a significant difference between the two groups (P < 0.05).@*CONCLUSION@#Genetic screening can provide an effective supplement to newborn hearing screening, and the combined screening can provide a best model for the prevention of hearing loss, which can enable early detection of deafness risks, targeted prevention measures, and genetic counseling to provide accurate prognosis for the newborns.

Nesse sentido, além de controlar as variáveis de idade na cirurgia e acesso à terapia fonoaudiológica para o desenvolvimento das habilidades auditivas e de linguagem, conhecer as famílias e de que maneira ela influencia no desempenho das crianças é extremamente válido, pois pode melhorar o acolhimento e direcionar melhor o aconselhamento. Objetivo: verificar a relação entre as categorias de audição e de linguagem considerando a idade na cirurgia e a relação entre as categorias de audição, linguagem e de envolvimento familiar em crianças usuárias de implante coclear. Método: A amostra estudada foi composta por 15 crianças com idade entre 2,2 e 8,3 anos. Foram utilizados questionários que mensuravam a percepção auditiva, a percepção de fala e o uso da linguagem pelas crianças. Foi aplicada também a escala de avaliação do envolvimento familiar para o auxílio na categorização das crianças a partir da audição e da linguagem. Resultados: Houve relação significante entre categorias de audição e envolvimento familiar e audição e linguagem. Não houve relação entre a idade da criança na cirurgia e as categorias de audição e de linguagem. Também não houve relação entre o envolvimento familiar e linguagem. Conclusão: A idade da criança na implantação do dispositivo não se relacionou com a classificação das categorias de audição e de linguagem. As crianças de famílias mais participativas apresentaram melhores índices de desenvolvimento auditivo.


Introduction: Cochlear implant benefits the individual with hearing loss both in language development and in improving the perception of speech sounds. Successful cochlear implant surgery, coupled with adequate stimulation and correct monitoring, provide a better development of children's hearing and language skills. In this sense, in addition to controlling the variables of age at surgery and access to speech therapy for the development of auditory and language skills, knowing the families and how it influences the children's performance is extremely valid, as it can improve the reception and better target counseling. Objective: To verify the relationship between the categories of hearing and language considering the age at surgery and the relationship between the categories of hearing, language and family involvement in children with cochlear implants. Method: The studied sample consisted of 15 children aged between 2.2 and 8.3 years. Questionnaires were used that measured auditory perception, speech perception and language use by children. The family involvement assessment scale was also applied to help categorize children based on hearing and language. Results: There was a significant relationship between hearing and family involvement and hearing and language categories. There was no relationship between the child's age at surgery and the hearing and language categories. There was also no relationship between family involvement and language. Conclusion: The child's age at device implantation was not related to the classification of hearing and language categories. Children from more participatory families presented better rates of auditory development.

ABSTRACT

Introdução: A Diabetes Mellitus (DM) é um distúrbio metabólico causado pela ausência ou diminuição da secreção de insulina ou por alterações do funcionamento deste hormônio no organismo, podendo envolver alterações físicas e cognitivas. Objetivo: Analisar os aspectos audiológicos e cognitivos de adultos com Diabetes Mellitus tipo 2. Método: Estudo transversal realizado em pessoas com idade entre 18 e 59 anos, de ambos os gêneros. Os participantes foram divididos em dois grupos: Grupo Estudo (GE) - pessoas com diagnóstico de Diabetes Mellitus e o Grupo Controle (GC) - pessoas sem Diabetes. Todos foram submetidos à avaliação glicêmica, cognitiva e audiológica. Para análise estatística foi utilizado o teste de Mann-Whitney, sendo estipulado o nível de significância de 0,05. Resultados: Participaram do estudo 32 indivíduos sendo 19 (59,4%) no GE e 13 (40,6%) no GC. A média de idade dos participantes foi de 46,8 ± 8,3 anos, com escolaridade média de 6,8 ± 6 anos, sendo 25 (78,1%) do gênero feminino e 7 (21,9%) do masculino. Foi observada diferença estatisticamente significativa entre os grupos para a pontuação referente à atenção e cálculo, recordação e escore total do MEEM, com pior desempenho no GE. Não foi observada diferença estatisticamente significante entre os grupos nos aspectos audiológicos avaliados. Conclusão: Indivíduos com Diabetes Mellitus tipo 2 não apresentaram riscos para alterações audiológicas com os instrumentos utilizados, entretanto apresentaram um alto risco para alterações cognitivas. Os achados demonstram que o acompanhamento fonoaudiológico constante é essencial para identificar as alterações precocemente.


Introduction: Diabetes Mellitus (DM) is a metabolic disorder caused by the absence or reduction of insulin secretion or by changes in the functioning of this hormone in the body, which may involve physical and cognitive changes. Objective: To analyze the audiological and cognitive aspects of type 2 Diabetes Mellitus in adults. Method: Cross-sectional study carried out in people aged between 18 and 59 years, of both genders. Participants were divided into two groups: Study Group (SG) - people diagnosed with Diabetes Mellitus and the Control Group (CG) - people without Diabetes. All underwent glycemic, cognitive and auditory assessment. Mann-Whitney's test was used for statistical analysis, with a significance level of 0.05. Results: 32 individuals participated in the study, 19 (59.4%) in the EG and 13 (40.6%) in the CG. The mean age of the participants was 46.8 ± 8.3 years, with a mean education of 6.8 ± 6 years, with 25 (78.1%) females and 7 (21.9%) males. A statistically significant difference was observed between the groups for the score related to attention and calculation, recall and total Mini-Mental State Examination (MMSE) score, with worse performance in the EG. There was no statistically significant difference between the groups regarding the audiological aspects evaluated. Conclusion: Individuals with type 2 Diabetes Mellitus did not present risks for audiological alterations, however they presented a high risk for cognitive alterations. the findings demonstrate that constant speech therapy monitoring is essential to identify changes early.

ABSTRACT

Programas de saúde auditiva estão voltados predominantemente para crianças entre 0 e 3 anos de idade ou para os maiores de 7. As crianças entre estas duas faixas etárias não estão em nenhum destes programas, porém é neste grupo que mais ocorrem problemas de orelha média, e, é, neste grupo, possível detectar as perdas auditivas mínimas, leves ou unilaterais que não foram identificadas nos programas de triagem auditiva neonatal. Objetivo: Identificar alterações auditivas em crianças pré-escolares por meio de um programa de triagem auditiva. Método: Trata-se de estudo descritivo, transversal e observacional realizado em duas escolas municipais do município de Mauá. A amostra foi composta por crianças de cinco e seis anos de idade. O programa de triagem auditiva foi composto: a. otoscopia; b. timpanometria, e c. registro das emissões otoacústicas transiente (EOAT) e produto de distorção (EOAPD). Em vista da pandemia iniciada em março de 2020, não foi possível avaliar as crianças de três e quatro anos. Resultados: 28,44% (n= 31) de crianças falharam na otoscopia. Das 78 (71,55%) crianças que passaram na otoscopia, 30,8% falharam na timpanometria; 16,7% nas Emissões Otoacústicas Produto de Distorção (DPOAE) e 19,2% nas Emissões Otoacústicas por estímulo Transiente (TPOAE); 30,76% (n= 24) das crianças falharam em pelo menos um dos três procedimentos. Conclusão: foram identificadas 30,76% de crianças com risco de alteração auditiva que devem ser encaminhadas para avaliação médica e audiológica.


Hearing health programs are predominantly aimed at children between 0 and 3 years of age or those older than 7. Children between these two age groups are not in any of these programs, but it is in this group that the most middle ear problems occur, and, it is in this group, possible to detect minimal, mild, or unilateral hearing loss that was not identified in neonatal hearing screening programs. Objective: To identify hearing alterations in preschool children through a hearing screening program. Method: This is a descriptive, cross-sectional, and observational study conducted in two municipal schools in the municipality of Mauá. The sample consisted of children aged five and six years. The hearing screening program was composed of a. otoscopy; b. tympanometry and, c. recording of transient otoacoustic emissions (TOAE) and distortion product (DPOAE). In view of the pandemic that began in March 2020, it was not possible to evaluate the three and four-year-old children. Results: 28.44% (n= 31) of the children failed otoscopy. Of the 78 (71.55%) children who underwent otoscopy, 30.8% failed tympanometry: 16.7% in Distortion Product Otoacoustic Emissions (DPOAE) and 19.2% in Transient Stimulus Otoacoustic Emissions (TPOAE); 30.76% (n= 24) of the children failed at least one of the three procedures. Conclusion: 30.76% of children at risk of hearing impairment were identified and should be referred for medical and audiological evaluation.


Los programas de salud auditiva están dirigidos principalmente a niños entre 0 y 3 años o mayores de 7 años. Los niños entre estos dos grupos de edad no están en ninguno de estos programas, pero es en este grupo que ocurren la mayoría de los problemas del oído medio, y, es en este grupo, posible detectar la pérdida de audición mínima, leve o unilateral que no se identificó en los programas de cribado auditivo neonatal. Objetivo: Identificar las alteraciones auditivas en niños en edad preescolar a través de un programa de detección auditiva. Método: Se trata de un estudio descriptivo, transversal y observacional realizado en dos colegios municipales del municipio de Mauá. La muestra estuvo constituida por niños de cinco y seis años y sus padres/tutores. El programa de detección de audición estuvo compuesto por: a. Cuestionario para padres/tutores sobre la historia de la salud auditiva de los niños; b. otoscopia; c. timpanometria y, d. Registro de emisiones otoacústicas transitorias (EOT) y producto de distorsión (DPOAE). Ante la pandemia que comenzó en marzo de 2020, no fue posible realizar los reexámenes ni evaluar a los niños de tres y cuatro años. Resultados: 28,44% (n= 31) de los niños no pasaron la otoscopia. De los 78 (71,55%) niños que se sometieron a otoscopia, 30,8% fallaron la timpanometria; 16,7% en emisiones otoacústicas de productos de distorsión (DPOAE) y 19,2% en emisiones otoacústicas de estímulo transitorio (TPOAE); 30,76% (n= 24) de los niños fallaron por lo menos uno de los tres procedimientos. Conclusión: 30,76% de los niños con riesgo de deficiencia auditiva fueron identificados y deben ser referidos para evaluación médica y audiológica.

ABSTRACT

Introducción: se ha descrito que los pacientes con hipoacusia asimétrica cursan en un 2% con lesiones retrococleares. La conducta de escrutinio se ha basado en la audiometría. Existen varias definiciones de asimetría audiométrica descritas en la literatura, pero sin llegar a un consenso. Aunque la prueba de oro para el diagnóstico de schwannoma vestibular es la resonancia magnética con gadolíneo, la sospecha clínica se hace en base a la asimetría audiométrica. Objetivo: hacemos una revisión de los trabajos publicados al respecto en la literatu-ra y comentamos nuestra experiencia. Reflexión: queremos enfatizar en la importancia de estudiar a los pacientes con hipoacusia asimétrica con el fin de descartar patología retrococlear. Conclusión: a pesar de que no existe un consenso claro en la definición de hi-poacusia asimétrica, la sospecha clínica de un schwannoma vestibular se basa en la audiometría


Background: It is described that 2% of patients with asymmetric hearing loss have retrocochlear lesions. The scrutiny behavior has been based on audiometry. There are several definitions of audiometric asymmetry described in the literature, but without reaching a consensus. Although the gold standard for the diagnosis of vestibular schwannoma is gadolinium magnetic resonance imaging, the clinical sus-picion is based on audiometric asymmetry. Objective: we review the results published in this regard in the literature and com-ment on our own experience. Reflection: we want to emphasize the importance of studying asymmetric hearing loss patients in order to rule out retrocochlear etiology. Conclusions: although there is no clear consensus on the definition of asym-metric hearing loss, the clinical suspicion of a vestibular schwannoma is based on the audiometry.

ABSTRACT

This paper analyzes the shortcomings of the existing pure tone audiometers, and proposes a system to realize pure tone audiometry and speech audiometry with a new DSP processor. The pure tone test signal produced by the system has accurate frequency, high signal-to-noise ratio, and small harmonic distortion. The noise generator that comes with DSP adds a band-pass filter to realize the generation of narrow-band noise. At the same time, due to the modular structure of software design, the system has good ease of use and scalability. The test results show that the hearing test system has excellent performance and can be better used in hearing medical diagnosis.

ABSTRACT

In mammals, the piezoelectric protein, Prestin, endows the outer hair cells (OHCs) with electromotility (eM), which confers the capacity to change cellular length in response to alterations in membrane potential. Together with basilar membrane resonance and possible stereociliary motility, Prestin-based OHC eM lays the foundation for enhancing cochlear sensitivity and frequency selectivity. However, it remains debatable whether Prestin contributes to ultrahigh-frequency hearing due to the intrinsic nature of the cell's low-pass features. The low-pass property of mouse OHC eM is based on the finding that eM magnitude dissipates within the frequency bandwidth of human speech. In this study, we examined the role of Prestin in sensing broad-range frequencies (4-80 kHz) in mice that use ultrasonic hearing and vocalization (to >100 kHz) for social communication. The audiometric measurements in mice showed that ablation of Prestin did not abolish hearing at frequencies >40 kHz. Acoustic associative behavior tests confirmed that Prestin-knockout mice can learn ultrahigh-frequency sound-coupled tasks, similar to control mice. Ex vivo cochlear Ca2+ imaging experiments demonstrated that without Prestin, the OHCs still exhibit ultrahigh-frequency transduction, which in contrast, can be abolished by a universal cation channel blocker, Gadolinium. In vivo salicylate treatment disrupts hearing at frequencies <40 kHz but not ultrahigh-frequency hearing. By pharmacogenetic manipulation, we showed that specific ablation of the OHCs largely abolished hearing at frequencies >40 kHz. These findings demonstrate that cochlear OHCs are the target cells that support ultrahigh-frequency transduction, which does not require Prestin.

ABSTRACT

La audición funcional ­para fines prácticos­ consiste en la posibilidad de despertar sensaciones precisas en regiones específicas del cerebro, a partir del procesamiento y extracción de mensajes ocultos en los cambios en la presión de las moléculas del aire que nos rodea. Medir la funcionalidad de la audición en un ser humano se convierte en un reto titánico que implica que nuestra vida profesional transcurra analizando información tanto subjetiva como objetiva de nuestros pacientes, ambas con un valor diagnóstico innegable. En cuanto a la primera, la historia clínica, las observaciones de la conducta auditiva del paciente, los reportes de la casa, la escuela y la terapia, o de estudios como la audiometría tonal y la logoaudiometría, resultan fundamentales no solo para el diagnóstico, sino para el seguimiento de nuestros pacientes. Sin embargo, en el caso de los pacientes más pequeños, o ante la necesidad de evaluar aspectos como la presión del oído medio, la función de las células ciliadas, o la presencia de microfónica coclear, la utilidad de esas herramientas subjetivas se encuentra limitada y entonces los registros, trazos, curvas y cifras relativas a intensidades, presiones, latencias, frecuencias, amplitudes y demás datos obtenidos a través de estudios objetivos, son los recursos que usamos para diagnosticar e iniciar la habilitación o rehabilitación de nuestros pacientes.


Functional hearing ­ for practical purposes ­ consists of the possibility of awakening precise sensations in specific regions of the brain from the processing and extraction of hidden messages in changes in the pressure of the molecules of the air that surrounds us. Measuring the functionality of hearing in a human being becomes a titanic challenge that implies that our professional life is spent analyzing both subjective and objective information from our patients, both with an undeniable diagnostic value: as for the first, the clinical history, observations of the patient's listening behavior, reports from home, school and therapy, or studies such as pure tone audiometry and speech audiometry, are essential not only for diagnosis but also for the follow-up of our patients. However, in the case of smaller patients, or when faced with the need to evaluate aspects such as middle ear pressure, hair cell function, or the presence of cochlear microphonics; The usefulness of these subjective tools is limited and therefore the records, traces, curves and figures related to intensities, pressures, latencies, frequencies, amplitudes and other data obtained through objective studies are the resources we use to diagnose and start the investigation. rehabilitation or rehabilitation of our patients.

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

Introdução: Dificuldades de desempenho comunicativo e de reconhecimento de fala em ambientes ruidosos são associadas ao envelhecimento. O declínio do reconhecimento da fala com ruído competitivo é devido a uma combinação de fatores auditivos e não-auditivos que acentuam ao longo do tempo e com o avanço da idade. Objetivo: Identificar os aspectos cognitivos e auditivos que contribuem para o declínio do reconhecimento de fala no ruído em idosos. Método: Trata-se de um estudo prospectivo, analítico, observacional e transversal. A amostra foi composta por dois grupos: um de adultos e outro de idosos, selecionados conforme os seguintes critérios de inclusão: ouvintes normais; idade entre 18 e 70 anos, de ambos os sexos. Os aspectos cognitivos foram analisados pelo Montreal Cognitive Assessment e, nos processos auditivos, foram aplicados testes de audiometria tonal limiar, psicofísicos de reconhecimento de fala em escuta difícil e de resolução temporal. Resultados: Quando comparados por grupo etário, os testes psicoacústicos apresentaram diferenças significativas nas condições: 1) SSI / OD - S/R 0 (p=0,001), 2) SSI / OD - S/R -15 (p=0,000), 3) HINT / OE S/R -10 (p=0,03), 5) HINT / OE S/R -15 (p= 0,02) quando aplicado o teste Mann Whitney U. Quando comparados por grupo etário, os testes GIN e TDD não apresentaram diferenças significativas. Já quando os testes psicoacústicos foram comparados independentes do grupo etário, os sujeitos com MoCA normal e alterados não apresentaram diferenças significativas (p=0,280). Conclusão: A partir da amostra estudada, observou-se que os aspectos cognitivos não contribuíram no desempenho da percepção de fala com estímulos competitivos quando comparados os grupos de adultos e idosos. Por outro lado, os aspectos auditivos avaliados mostraram que os idosos apresentam maiores dificuldades de compreensão da fala no ruído quando comparados aos indivíduos mais jovens.


Introduction: Difficulties in communicative performance and speech recognition in noise are associated with aging. The decline in speech recognition with competitive noise is due to a combination of auditory and non-auditory factors that worsens over time and with aging. Objective: To identify the cognitive and auditory aspects that contribute to the decline of speech recognition in noise in the elderly. Method: This is a prospective, analytical, observational and cross-sectional study. The sample consisted of two groups: one of adults and one of elderly, selected according to the following inclusion criteria: normal listeners; between 18 and 70 years old, of both sexes. The cognitive aspects were analyzed with the Montreal Cognitive Assessment and, in the auditory processes, pure-tone audiometry threshold tests, psychophysical speech recognition in difficult listening and temporal resolution were applied. Results: When compared by age group, psychoacoustic tests showed significant differences in conditions: 1) SSI / RE - SNR 0 (p = 0.001), 2) SSI / RE - SNR -15 (p = 0.000), 3) HINT / LE SNR -10 (p = 0.03), 5) HINT / LE SNR -15 (p = 0.02) when the Mann Whitney U test was applied. GIN and DDT tests did not show significant differences. When the psychoacoustic tests were compared regardless of the age group, the subjects with normal and changed MoCA did not present significant differences (p = 0.280). Conclusion: From the studied sample, cognitive aspects did not contribute to the performance of speech perception with competitive stimuli when comparing the adults and the elderly. On the other hand, the assessed auditory aspects showed that the elderly have greater difficulties in understanding speech in noise when compared to younger individuals.


Introducción: Las dificultades en el desempeño comunicativo y el reconocimiento del habla en entornos ruidosos están asociadas con el envejecimiento. La disminución del reconocimiento de voz con ruido competitivo se debe a una combinación de factores auditivos y no auditivos que se acentúan con el tiempo y con la edad. Objetivo: Identificar los aspectos cognitivos y auditivos que contribuyen al declive del reconocimiento del habla en ruido en las personas mayores. Método: Se trata de un estudio prospectivo, analítico, observacional y transversal. La muestra estuvo conformada por dos grupos: uno para adultos y otro para ancianos, seleccionados según los siguientes criterios de inclusión: oyentes normales; entre 18 y 70 años, de ambos los sexos. Los aspectos cognitivos fueron analizados por la Evaluación Cognitiva de Montreal y, en los procesos auditivos, se aplicaron pruebas de audiometría tonal umbral, reconocimiento psicofísico del habla en audiencias difíciles y resolución temporal. Resultados: Cuando se compararon por grupo de edad, las pruebas psicoacústicas mostraron diferencias significativas en las condiciones: 1) SSI / OD - S / R 0 (p = 0,001), 2) SSI / OD - S / R -15 (p = 0,000), 3 ) HINT/ OE S / R -10 (p = 0.03), 5) HINT / OE S / R -15 (p = 0.02) cuando se aplicó la prueba Mann Whitney U. Las pruebas GIN y TDD no mostraron diferencias significativas. Cuando se compararon las pruebas psicoacústicas independientemente del grupo de edad, los sujetos con MoCA normal y alterado no presentaron diferencias significativas (p = 0,280). Conclusión: De la muestra estudiada, se observó que los aspectos cognitivos no contribuyeron al desempeño de la percepción del habla con estímulos competitivos al comparar los grupos de adultos y ancianos. Por otro lado, los aspectos auditivos evaluados mostraron que los ancianos tienen mayores dificultades para comprender el habla en ruido en comparación con los más jóvenes.

ABSTRACT

Abstract Introduction: Hearing impairment, or hearing loss, can be caused by several factors and the implications vary according to the type, degree, cause and age of occurrence. Hearing screening should be a common procedure, allowing the pre-clinical identification and necessary referrals, avoiding the consequences of auditory deprivation. Mobile apps have shown to be a good alternative for hearing assessment. Objective: The objective was to develop an app and assess its performance in identifying hearing loss by comparing it with another validated screening tool. Methods: The application, called Ouviu, was created using audiological knowledge and tools available on the iOS platform. We evaluated 185 people, aged between 6 and 96 years, distributed into 5 age groups, performing audiometry and hearing screening using two tools: HearCheck and the application. Results: The results showed that the sensitivity of the application in identifying hearing loss was approximately 97%, while that of HearCheck was 79%. The positive predictive value of the application showed that the probability of a person being identified with this tool and actually having a hearing loss was 94%, while for HearCheck it was 96%. False negatives, which failed hearing loss identification, were fewer in the app (3%) than in HearCheck (21%). Conclusion: Consequently, the developed application was shown to be effective as a hearing screening tool, surpassing HearCheck in identifying mild hearing loss. In addition to being portable, easy to apply, low cost and rapidly performed, the application has the advantage of assessing environmental noise to perform the exam, as well as the fact that it is not necessary to attach any hardware to the mobile device.


Resumo Introdução: O comprometimento da audição, ou perda auditiva, pode ser ocasionado por diversos fatores e as implicações variam de acordo com o tipo, grau, causa e idade de acometimento. A triagem auditiva deveria ser um procedimento usual que possibilitasse a identificação pré-clínica e os encaminhamentos necessários, evitaria as consequências da privação desse sentido. Aplicativos móveis mostram-se uma boa opção. Objetivo: Desenvolver um aplicativo e verificar seu desempenho na identificação de perda auditiva comparado com outro instrumento de rastreio validado. Método: O aplicativo, chamado Ouviu, foi criado com o conhecimento audiológico e as ferramentas disponíveis na plataforma iOS. Avaliamos 185 pessoas, entre 6 e 96 anos, distribuídas em 5 grupos, fizemos audiometria e rastreio auditivo por meio de dois instrumentos: HearCheck e aplicativo. Resultados: Ficou evidenciado que a sensibilidade do aplicativo para identificar perda auditiva foi aproximadamente 97%, enquanto a do HearCheck foi 79%. O valor preditivo positivo do aplicativo mostrou que a probabilidade de uma pessoa ser identificada com esse instrumento e realmente ter perda auditiva foi 94%, o HearCheck foi de 96%. Os falsos negativos, que deixaram de identificar perda auditiva, foram menores no aplicativo (3%) que no HearCheck (21%). Conclusão: O aplicativo desenvolvido mostrou-se eficaz como uma ferramenta de rastreio auditivo. É melhor do que HearCheck na identificação de perda auditiva leve. Além de ser portátil, de fácil aplicação, baixo custo e rápida execução, o aplicativo tem a vantagem de avaliar o ruído ambiental para fazer o exame e também a não necessidade de quaisquer hardwares para acoplar ao dispositivo móvel.

ABSTRACT

Abstract Introduction: The personal frequency modulation system is an assisted technology resource used in the accessibility of individuals with hearing impairment, being very important in the school environment. Ordinance number 1274/2013 included this device into the Brazilian unified health system. Objective: To analyze the distribution the personal frequency modulation system concession in the national territory by the Brazilian unified health system from 2013 to 2017. Methods: This is an ecological study that uses the 27 federation units and the five geographic regions as analysis units. The population involved students in the age range of 5-17 years who reported severe hearing impairment. The data sources were the ambulatory information system/Brazilian unified health system, the Brazilian institute of geography and statistics and the report no. 58 of the national commission for the incorporation of technologies into Brazilian unified health system, national commission of technologies incorporation of the ministry of health. The spatial analysis was carried out through the percentage of coverage of the frequency modulation system concession per federation unit; the data were then unified in the five geographic regions and descriptive statistical analysis was performed. Results: Between the first and second years, there was an increase of almost 50% in the quantity dispensed, however, there was a progressive decline in the following years. The average coverage of the frequency modulation system in Brazil was 33.4%. The spatial exploratory analysis showed there is a low and uneven distribution in the territory, as the South and Southeast regions had the highest coverage and the North and Northeast regions the lowest, except for the Rio Grande do Norte unit. Conclusion: The frequency modulation system concession was below that stipulated by the ministry of health and from 2014 to 2017, the dispensed quantity progressively decreased. There is an unequal distribution in the territory that can be explained by the geographic disposition of hearing health services.


Resumo Introdução: O sistema de frequência modulada pessoal é um recurso de tecnologia assistida usado na acessibilidade das pessoas com deficiência auditiva, é muito importante no ambiente escolar. A portaria n◦ 1.274/2013 inseriu esse dispositivo no Sistema Único de Saúde. Objetivo: Analisar a distribuição no território nacional da concessão do sistema de frequência modulada pessoal pelo Sistema Único de Saúde no período de 2013 a 2017. Método: Estudo ecológico que usa como unidade de análise as 27 unidades de federação e as cinco regiões geográficas. A população foram os estudantes na faixa de 5 a 17 anos que referiram ter deficiência auditiva com comprometimento severo. As fontes de dados foram o Sistema de Informações Ambulatoriais/Sistema Único de Saúde, Instituto Brasileiro de Geografia e Estatística e o relatório n◦ 58 da Comissão Nacional de Incorporação de Tecnologias no Sistema Único de Saúde do Ministério da Saúde. Foi feita a análise espacial, através da porcentagem da cobertura da concessão do sistema frequência modulada por unidade de federação e em seguida, os dados foram unificados nas cinco regiões geográficas e foi feita a análise estatística descritiva. Resultados: Entre o primeiro e segundo ano foi observado um aumento de quase 50% da quantidade dispensada, porém nos anos seguintes constatamos um declínio progressivo. A média da cobertura do sistema frequência modulada no Brasil foi de 33,4%. Na análise exploratória espacial observamos que existe uma baixa e desigual distribuição no território, as regiões Sul e Sudeste apresentaram as maiores coberturas e as regiões Norte e Nordeste as menores, exceto para a unidade do Rio Grande do Norte. Conclusões: A concessão do sistema frequência modulada foi abaixo do estipulado pelo Ministério da Saúde e de 2014 a 2017 o quantitativo dispensado diminuiu progressivamente. Existe uma distribuição desigual no território que pode ter explicado a disposição geográfica dos serviços de saúde auditiva.
