A case of sudden hearing loss combined with familial hyperlipidemia / 临床耳鼻咽喉头颈外科杂志

Hyperlipidemia is characterized by elevated levels of blood lipids. The clinical manifestations are mainly atherosclerosis caused by the deposition of lipids in the vascular endothelium. The link between abnormal lipid metabolism and sudden hearing loss remains unclear. This article presents a case study of sudden hearing loss accompanied by familial hyperlipidemia. Pure tone audiometry indicated intermediate frequency hearing loss in one ear. Laboratory tests showed abnormal lipid metabolism, and genetic examination identified a heterozygous mutation in theAPOA5 gene. Diagnosis: Sudden hearing loss; hypercholesterolemia. The patient responded well to pharmacological treatment. This paper aims to analyze and discuss thepotential connection between abnormal lipid metabolism and sudden hearing loss.

Genetic characteristic analysis of slight-to-moderate sensorineural hearing loss in children / 临床耳鼻咽喉头颈外科杂志

Objective:To analyze genetic factors and phenotype characteristics in pediatric population with slight-to-moderate sensorineural hearing loss. Methods:Children with slight-to-moderate sensorineural hearing loss of and their parents, enrolled from the Chinese Deafness Genome Project, were studied. Hearing levels were assessed using pure tone audiometry, behavioral audiometry, auditory steady state response（ASSR）, auditory brainstem response（ABR） thresholds, and deformed partial otoacoustic emission（DPOAE）. Classification of hearing loss is according to the 2022 American College of Medical Genetics and Genomics（ACMG） Clinical Practice Guidelines for Hearing Loss. Whole exome sequencing（WES） and deafness gene Panel testing were performed on peripheral venous blood from probands and validations were performed on their parents by Sanger sequencing. Results:All 134 patients had childhood onset, exhibiting bilateral symmetrical slight-to-moderate sensorineural hearing loss, as indicated by audiological examinations. Of the 134 patients, 29（21.6%） had a family history of hearing loss, and the rest were sporadic patients. Genetic causative genes were identified in 66（49.3%） patients. A total of 11 causative genes were detected, of which GJB2 was causative in 34 cases（51.5%）, STRC in 10 cases（15.1%）, MPZL2 gene in six cases（9.1%）, and USH2A in five cases（7.6%）.The most common gene detected in slight-to-moderate hearing loss was GJB2, with c. 109G>A homozygous mutation found in 16 cases（47.1%） and c. 109G>A compound heterozygous mutation in 9 cases（26.5%）. Conclusion:This study provides a crucial genetic theory reference for early screening and detection of mild to moderate hearing loss in children, highlighting the predominance of recessive inheritance and the significance of gene like GJB2, STRC, MPZL2, USH2A.

Comparative study of surgical effects on patients with mixed deafness and otosclerosis with different air bone conduction differences / 中华耳鼻咽喉头颈外科杂志

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.

Application Progress of Objective Audiological Detection Techniques in Forensic Clinical Medicine / 法医学杂志

The qualitative, quantitative, and localization analysis of hearing loss is one of the important contents of forensic clinical research and identification. Pure-tone audiometry is the "gold standard" for hearing loss assessment, but it is affected by the subjective cooperation of the assessed person. Due to the complexity of the auditory pathway and the diversity of hearing loss, the assessment of hearing loss requires the combination of various subjective and objective audiometric techniques, along with comprehensive evaluation based on the case situation, clinical symptoms, and other examinations to ensure the scientificity, accuracy and reliability of forensic hearing impairment assessment. Objective audiometry includes acoustic impedance, otoacoustic emission, and various auditory evoked potentials. The frequency-specific auditory brainstem response (ABR), 40 Hz auditory event related potential, and auditory steady-state response are commonly used for objective hearing threshold assessment. The combined application of acoustic impedance, otoacoustic emission and ABR can be used to locate hearing loss and determine whether it is located in the middle ear, cochlea, or posterior cochlea. This article reviews the application value of objective audiometry techniques in hearing threshold assessment and hearing loss localization, aiming to provide reference for forensic identification of hearing loss.

Development of High-performance Hearing Test System / 中国医疗器械杂志

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.

Emissões otoacústicas evocadas na doença de Ménière / Otoacoustic emissions evoked in Ménière's disease

RESUMO Objetivo Verificar as respostas das emissões otoacústicas (EOA) evocadas por estímulo transiente e produto de distorção em indivíduos com doença de Ménière. Métodos Estudo transversal com casuística composta por 60 indivíduos de 19 a 75 anos de idade, distribuídos em dois grupos: grupo estudo, com 32 indivíduos com diagnóstico médico de doença de Ménière, sem outros riscos, e grupo controle formado por 28 indivíduos com perda coclear, sem doença de Ménière, pareado por idade e gênero ao grupo estudo. Critério de elegibilidade: curva tipo A, sem perda condutiva ou mista ou suspeita de alteração retrococlear. A avaliação audiológica foi composta por anamnese, inspeção do meato acústico externo, audiometria tonal limiar, logoaudiometria, medidas de imitância acústica e emissões otoacústicas evocadas por estímulo transiente e produto de distorção. Resultados Os indivíduos com Ménière apresentaram maior ocorrência de perda unilateral, zumbido pitch grave, vertigem e plenitude auricular em relação ao controle. Nesses indivíduos, houve maior incompatibilidade entre os resultados das EOA e da audiometria tonal: nas perdas unilaterais, observaram-se alterações nas EOA nas orelhas com limiares auditivos normais do lado contralateral, caracterizando disfunções cocleares. Nas orelhas com perda coclear, houve presença de EOAT (por estímulo transiente) e ausência de EOAPD (produto de distorção), contrapondo-se ao grupo controle, que apresentou ausência de EOAT e de EOAPD, como o esperado em perdas cocleares de outras etiologias. Conclusão A pesquisa das emissões na doença de Ménière identificou disfunção coclear na orelha contralateral nos casos unilaterais e presença de EOAT com ausência de EOAPD nas orelhas com perda auditiva, diferenciando-se das perdas cocleares de outras etiologias.

ABSTRACT Purpose To verify the responses of Evoked Otoacoustic Emissions by transient stimulus and distortion product in individuals with Ménière's Disease. Methods Cross-sectional study with a sample composed of 60 individuals, aged 19 to 75 years, divided into two groups: study group, with 32 individuals with a medical diagnosis of Ménière's disease, without other risks and a control group formed by 28 individuals with cochlear loss without Meniere's disease, age and sex matched to the study group. Eligibility criteria: type A curve, without conductive or mixed loss or suspected retrocochlear alteration. The audiological evaluation consisted of anamnesis, inspection of the external acoustic meatus, pure tone audiometry, logoaudiometry, measures of acoustic immittance and transient evoked otoacoustic emissions and distortion product. Results Individuals with Ménière's disease had a higher occurrence of unilateral hearing loss, low pitch tinnitus, vertigo and ear fullness in relation to the control. In these individuals, there was greater incompatibility between the results of OAE and pure tone audiometry: in unilateral hearing loss, alterations in OAE were observed in ears with normal hearing thresholds on the contralateral side, characterizing cochlear dysfunctions. In the ears with cochlear loss, there was the presence of TEOAE and absence of DPOAE, in contrast to the control group, which showed the absence of TEOAE and DPOAE, as expected in cochlear losses of other etiologies. Conclusion The investigation of emissions in Ménière's disease identified cochlear dysfunction in the contralateral ear in unilateral cases and the presence of TOAE with absence of DPOAE in ears with hearing loss, differentiating from cochlear losses of other etiologies.

Configuração audiométrica descendente: médias tonais, percepção de fala e desvantagem auditiva / Descending audiometric configuration: tonal means, speech perception and audiological hearing disadvantage

RESUMO Objetivo Verificar a correlação das diferentes médias tonais (tritonal, quadritonal e octonal) com o Índice Percentual de Reconhecimento de Fala e com a desvantagem auditiva. Métodos Participaram do estudo 56 sujeitos, distribuídos em dois grupos, com configuração audiométrica descendente: Grupo 1 (G1) - 28 sujeitos com média tritonal igual ou inferior a 25 dBNA e Grupo 2 (G2) - 28 sujeitos com média tritonal pior que 25 dBNA (G2), sendo pareados quanto ao gênero e idade (p= 0,544). Todos foram submetidos à audiometria tonal liminar, Índice Percentual de Reconhecimento de Fala (IPRF) com lista monossilábica de palavras gravadas, medidas de imitância acústica e ao questionário Hearing Handicap Inventory for Adults. A análise de correlação foi realizada entre as médias de três frequências (M3), de quatro frequências (M4) e de oito frequências (M8) com o IPRF e com a desvantagem auditiva, utilizando o teste de correlação de Spearman, sendo o nível de significância considerado <0,05 (5%). Resultados Evidenciou-se correlação estatisticamente significativa do IPRF com a M8, para o G1, e do IPRF com M4 e M8, para o G2. Observou-se tendência à significância, tanto para o G1, como para o G2, em relação à M8, quando correlacionada com a desvantagem auditiva, demonstrando que analisar as oito frequências do audiograma (frequências mais agudas que 4000 Hz) parece possibilitar maior compreensão em relação à desvantagem auditiva do paciente. Conclusão Houve correlação estatisticamente significativa do IPRF com a M8, nos dois grupos, denotando uma redução no desempenho do IPRF, com o aumento da média, considerando as oito frequências. A M8 refletiu melhor a desvantagem auditiva causada pela perda auditiva, no G1.

ABSTRACT Purpose To verify the correlation of different tonal means (tritonal, quadritonal and octanol) with the Percentage Index of Speech Recognition and with hearing disadvantage. Methods 56 subjects participated in the study, distributed into two groups, with descendant audiometric configuration: Subjects with tritonal average equal to or less than 25 dB HL(G1) and subjects with a tritone average worse than 25 dB HL(G2), being matched for sex and age (p=0.544). All were safe by Threshold Tone Audiometry, Speech Recognition Percentage Index (IPRF) with a list of keywords, Acoustic I Measures and the Elearing Handicap Inventory for Adults. The correlation analysis was performed between the averages, of three frequencies (M3), of four frequencies (M4) and of eight frequencies (M8) with the IPRF and with auditory disadvantage, using the Spearman correlation test, the significance level being considered <0.05 (5%). Results There was a statistically significant correlation of the IPRF with M8 , for G1, and the IPRF with M4 and M8, for G2. There was a tendency towards significance, both for G1 and G2, in relation to M8 when correlated with hearing impairment, demonstrating that analyzing the eight frequencies of the audiogram (frequencies higher than 4000 Hz) seems to allow a greater understanding of the patient's hearing handicap. Conclusion There was a statistically significant correlation between the IPRF and M8, in both groups, denoting a reduction in the performance of the IPRF, with an increase in the mean, considering the eight frequencies. M8 better reflected the hearing disadvantage caused by the hearing loss in G1.

Association between cytogenetic alteration and the audiometric profile of individuals with Turner syndrome / Relação entre alteração citogenética e o perfil audiométrico de indivíduos com síndrome de Turner

Abstract Introduction: Turner syndrome is a frequent genetic disorder that affects female individuals and covers a large phenotypic variability. Scientific literature suggests an association between hearing loss and Turner syndrome, but it remains a controversial topic. Objective: To associate the cytogenetic alteration with the audiometric profile of individuals with Turner syndrome. Methods: Cross-sectional study, with a hospital-based, convenience sample. Patients diagnosed with Turner syndrome were included and those with difficulty understanding the audiometry and/or other associated syndromes were excluded. The participants were studied with pure tone audiometry. Results: Of the 65 patients included, 36.9% had X chromosome monosomy and 63.0% had other alterations. Regarding the audiometry, 64.6% had normal thresholds and 35.3% had hearing impairment. Of these, 30.4% had hybrid hearing loss, 26.0% alteration at 6 and/or 8 kHz, 17.3% had conductive hearing loss, 13.0% sensorineural loss and 13.0% had mixed hearing loss. We observed that the mild degree was the most frequent one. There was no statistically significant association between the cytogenetic type of Turner syndrome and the presence or absence of hearing loss, or with the type and degree of hearing loss. Conclusion: The cytogenetic alteration in Turner syndrome was not associated with the audiometric profile, which showed variability regarding the type and degree of hearing loss.

Hearing loss, tinnitus, and hypertension: analysis of the baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

OBJECTIVES: To investigate the association among hypertension, tinnitus, and sensorineural hearing loss and evaluate the influence of other covariates on this association. METHODS: Baseline data (2008-2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) were analyzed. Altogether, 900 participants were evaluated. The baseline assessment consisted of a 7-hour examination to obtain clinical and laboratory variables. Hearing was measured using pure-tone audiometry. RESULTS: Overall, 33.3% of the participants had hypertension. Participants with hypertension were more likely to be older, male, and diabetic compared to those without hypertension. The prevalence of tinnitus was higher among hypertensive participants and the odds ratio for tinnitus was higher in participants with hypertension than in those without hypertension. However, the difference was not significant after adjusting for age. Audiometric results at 250-8,000 Hz were worse in participants with hypertension than in those without hypertension in the crude analysis; however, the differences were not significant after adjustment for age, sex, diagnosis of diabetes, and exposure to noise. No significant difference was observed in hearing thresholds among participants having hypertension for <6 years, those having hypertension for ≥6 years, and individuals without hypertension. CONCLUSION: Hearing thresholds were worse in participants with hypertension. However, after adjusting for age, sex, diagnosis of diabetes, and exposure to noise, no significant differences were observed between participants with and without hypertension. A higher prevalence of tinnitus was observed in participants with hypertension compared to those without hypertension, but without significance after adjusting for age.

Método Amostra de 30 idosos, com idade igual ou superior a 60 anos, perda auditiva neurossensorial de grau moderado a severo simétrica bilateral de configuração descendente com limiares em 4kHz iguais ou inferiores a 70dBNA. Foram dois grupos. GTP (grupo tom puro): 15 idosos tiveram as próteses auditivas adaptadas com emprego dos limiares obtidos com tom puro e grupo GNB (grupo Narrowband): 15 idosos tiveram as próteses auditivas adaptadas por meio dos limiares obtidos com NB. Os procedimentos realizados antes da adaptação de próteses auditivas e após três meses de uso de amplificação foram: Escala COSI, IPRF (Índice Percentual de Reconhecimento de fala), Relação Sinal/Ruído e análise do tempo de uso do AASI. O Questionário Internacional de Aparelho de Amplificação Sonora Individual (QI-AASI) foi aplicado após três meses. Resultados Os idosos do grupo em que as próteses auditivas foram adaptadas com ganho prescrito com base nos limiares auditivos obtidos com o estímulo Narrow Band apresentaram melhor desempenho nos seguintes testes: IPRF à orelha direita, pontuação total do questionário QI-AASI, escala COSI e maior tempo de uso do AASI em comparação ao grupo GTP. Conclusão Observou-se maior benefício com o uso de próteses auditivas, pela pontuação total do questionário QI-AASI, escala COSI e maior tempo de uso do AASI, no grupo cuja prescrição do ganho acústico baseou-se nos limiares audiométricos obtidos com o Narrowband.

ABSTRACT Purpose To verify the benefit obtained by the prescription of acoustic gain based on the auditory thresholds obtained with pure tones modulated in frequency and with Narrow Band Noise. Methods The sample consisted of 30 elderly people, aged 60 years or over with moderate to severe descending sensorineural symmetrical hearing loss with thresholds at 4kHz equal to or less than 70dBHL. There were two groups. GTP (pure tone group): 15 elderly people had their hearing aids fitted through the auditory thresholds obtained with pure tone and the GNB group (narrow band group): 15 elderly people had their hearing aids fitted through the auditory thresholds obtained with NB. The procedures performed before the fitting of hearing aids and after three months of amplification use were: COSI, WRS (Word Recognition Score), Signal/Noise ratio. The International Outcome Inventory for Hearing Aids (IOI-HA) was applied only after three months of hearing aid fitting. Results The elderly people in the group in which the hearing aids were fitted with a prescribed gain based on the hearing thresholds obtained with the Narrow Band stimulus showed better performance in the following tests: WRS on the right ear, total score of the IOI-HA inventory, COSI and longer use of hearing aids compared to the GTP group. Conclusion There was a greater benefit with the use of hearing aids, due to the total score of the IOI-HA inventory, COSI scale and longer daily use time of hearing aids, in the group whose prescription of acoustic gain was based on the auditory thresholds obtained with narrow band.

Dysphonia, arterial hypertension, diabetes mellitus, thyroid diseases, and noise complaints as probable factors associated with hearing loss among teachers / Disfonia, hipertensão arterial, diabetes mellitus, doenças da tireoide e queixas de ruído como prováveis fatores associados a perda auditiva em professores

ABSTRACT Objective: to verify a possible association between hearing loss and dysphonia, arterial hypertension, diabetes mellitus, thyroid diseases, and noise complaints. Methods: a cross-sectional study involving 60 teachers, mean age 47.05 years. Pure-tone threshold audiometry was used to assess hearing, the voice questionnaire and voice acoustic evaluation were used for voice perception and quality, and the standardized questionnaire verified noise complaint and comorbidities. The statistical analysis was conducted with Mann-Whitney and Fisher's exact tests and multivariate linear regression. Results: there was a significant association between hearing loss and diabetes mellitus, hypertension, and thyroid disease (both p <0.0001), but there was no association between noise complaints and hearing loss in this population. The regression showed that dysphonia (p = 0.0311) and diabetes mellitus (p = 0.0302) are independent risk factors for hearing loss. A correlation was found between hearing loss and voice characteristics: roughness, breathiness, tension, and resonance. Conclusion: this study showed that hypertension and thyroid diseases are factors associated with hearing loss. In addition, dysphonia and diabetes mellitus are independent factors associated with hearing loss in teachers. These results show the need for policies aimed at promoting teachers' health.

RESUMO Objetivo: verificar possível associação da perda auditiva com disfonia, hipertensão arterial (HA), diabetes mellitus (DM), doenças da tireoide e queixas de ruído. Métodos: estudo transversal envolvendo 60 professores, média de idade de 47,05 anos. Foi avaliada a audição por meio da Audiometria tonal limiar, a percepção e qualidade vocal com o questionário vocal e a avaliação vocal acústica, enquanto a queixa de ruído e as comorbidades envolvidas foram investigadas com o questionário padronizado. A análise estatística utilizou os testes Ex-act de Mann Whitney, Fisher e regressão linear multivariada. Resultados: houve associação significante entre perda auditiva e DM, HA e doenças da tireoide (ambas p <0,0001), mas não foi encontrada associação entre queixa de ruído e perda auditiva nesta população. A regressão mostrou que as variáveis disfonia (p = 0,0311) e DM (p = 0,0302) são fatores de risco independentes para perda auditiva. Houve correlação entre perda auditiva e as características vocais rugosidade, soprosidade, tensão e ressonância. Conclusão: este estudo demostrou que HA e doenças da tireoide são fatores associados a perda auditiva, além disso a disfonia e DM se constituem em fatores associados independentes para a perda auditiva em professores.

Association between the auditory profile and speech-language-hearing diagnosis in children and adolescents / Associação entre o perfil auditivo e o diagnóstico fonoaudiológico em crianças e adolescentes

ABSTRACT Purpose: to verify the association between the auditory assessment result and the speech-language-hearing diagnosis in children and adolescents. Methods: an observational, cross-sectional study based on the analysis of medical records of children and adolescents that received care at a speech-language-hearing assessment outpatient center between 2010 and 2014. Data on sociodemographic characteristics, speech-language-hearing diagnosis, auditory examination results, and Auditory Processing Simplified Assessment results were collected. Descriptive and association analyses were conducted with either the chi-squared or Fisher's exact test, considering the 5% statistical significance level. Results: the sample comprised 122 participants, most of them males (67.2%), mean age 8.78 years. A statistically significant association was verified between the audiometry result and the diagnostic hypothesis of change in written language (p = 0.011); between the results of both the sequential memory test for nonverbal sounds and sound localization and the diagnostic hypotheses of change in the cognitive aspects of language (p = 0.019 and p = 0.033, respectively) and of speech (p = 0.003 and p = 0.020, respectively); and between the result of the sequential memory test for verbal sounds and the diagnostic hypothesis of change in speech (p = 0.005). Conclusion: given the associations found, it is proposed that children and adolescents with changes in speech undergo the Auditory Processing Simplified Assessment to verify the possibility of changed aspects, favoring directed therapeutic interventions.

RESUMO Objetivo: verificar a associação entre o resultado da avaliação auditiva e o diagnóstico fonoaudiológico de crianças e adolescentes atendidos em um ambulatório universitário. Métodos: trata-se de estudo observacional transversal, baseado em análise dos prontuários de crianças e adolescentes atendidos em um ambulatório de avaliação fonoaudiológica entre 2010 e 2014. Foram coletados dados referentes às características sociodemográficas, diagnóstico fonoaudiológico, resultados do exame auditivo e da Avaliação Simplificada do Processamento Auditivo. Foi realizada análise descritiva e de associação, utilizando o teste Qui-quadrado ou Exato de Fisher e considerando nível de significância estatística de 5%. Resultados: a amostra foi composta por 122 participantes, a maioria do sexo masculino (67,2%), com média de idade de 8,78 anos. Foi verificada associação estatisticamente significante entre o resultado da audiometria e a hipótese diagnóstica de alteração da linguagem escrita (p = 0,011); entre os resultados dos testes de Memória Sequencial Não Verbal e de localização sonora com as hipóteses diagnósticas de alteração dos aspectos cognitivos da linguagem (p = 0,019 e p = 0,033, respectivamente) e da fala (p = 0,003 e p = 0,020, respectivamente) e entre o resultado do teste de Memória Sequencial Verbal com a hipótese diagnóstica de alteração de fala (p = 0,005). Conclusão: diante das associações encontradas, propõe-se que crianças e adolescentes com alterações na fala realizem a Avaliação Simplificada do Processamento Auditivo com a finalidade de verificar possíveis aspectos alterados, favorecendo intervenções terapêuticas direcionadas.

Acurácia de instrumentos de custo acessível para triagem auditiva de adultos e idosos / Accuracy of affordable instruments for hearing screening in adults and the elderly

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.

Função auditiva, percepção da incapacidade e cognição em idosos: uma relação a elucidar / Hearing function, perception of disability (handicap) and cognition in the elderly: a relation to be elucidated

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.

Comparison of ASSR, ABR and 40 Hz AERP Response Thresholds at Different Frequencies and Their Forensic Applications / 法医学杂志

OBJECTIVES@#To explore the relationship between the frequency characteristics and response threshold of auditory steady-state response (ASSR), auditory brainstem response (ABR) and 40 Hz auditory event related potential (40 Hz AERP), and their application values in forensic medicine.@*METHODS@#Thirty volunteers with normal hearing (60 ears) were selected to perform pure tone audiometry (PTA) threshold and ASSR, ABR and 40 Hz AERP response threshold tests in the standard sound insulation shielding room, and the results were statistically analyzed by SPSS 22.0 software.@*RESULTS@#At 0.5 kHz and 1.0 kHz frequencies, the correlation between 40 Hz AERP response threshold and PTA threshold was good, which was better than that of ASSR and ABR response threshold. At 2.0 kHz and 4.0 kHz frequencies, the correlation between ASSR and ABR response thresholds and PTA threshold was good, which was better than that of 40 Hz AERP response threshold.@*CONCLUSIONS@#To evaluate the hearing at 0.5 kHz and 1.0 kHz frequencies, it is recommended to use 40 Hz AERP and ASSR to comprehensively assess the PTA threshold of the subjects. To evaluate the hearing at 2.0 kHz and 4.0 kHz frequencies, ABR and ASSR are recommended to assess the PTA threshold of subjects comprehensively. The combination of ASSR, ABR and 40 Hz AERP can improve the accuracy of hearing function evaluation.

Observed Frequency and Characteristics of Hearing Loss in Osteogenesis Imperfecta

ABSTRACT Background: Osteogenesis imperfecta (OI) is a rare group of genetic disorders affecting connective tissue, with consequent bone fragility, frequent fractures and skeletal deformity. Depending on the type, patients can have blue sclera, dentinogenesis imperfecta, and hearing loss. Aim: To determine the frequency, type and audiometric characteristics of hearing loss in a group of patients with OI. Material and Methods: A prospective cohort study was completed. A clinical and diagnostic hearing evaluation with tympanometry, acoustic stapedial reflex, pure-tone and speech audiometry were performed. Results: Thirty patients completed the study; mean age of 22 years (range 6-63 years). Sixty seven percent had a type I OI. Overall, nine (30%) patients had hearing loss (15/60 ears). Of these, six had bilateral hearing loss. Of the 15 affected ears, six showed conductive hearing loss, five sensorineural hearing loss, and four mixed hearing loss. Patients with hearing loss were older than patients with normal hearing. Only one pediatric patient developed hearing loss. Of the ears without hearing loss, 13% did not have an acoustic stapedial reflex. Conclusions: In this group of patients with OI, 30% had hearing loss and among those ears with normal hearing, 13% did not have an acoustic stapedial reflex. Patients with OI should be monitored for hearing loss.

Antecedentes: La osteogénesis imperfecta (OI) es un grupo raro de trastornos genéticos que afectan al tejido conectivo, con la consiguiente fragilidad ósea, fracturas frecuentes y deformidad esquelética. Según el tipo, los pacientes pueden presentar escleras azules, dentinogénesis imperfecta e hipoacusia. Objetivos: Determinar la frecuencia, tipo y características audiométricas de la hipoacusia en un grupo de pacientes con OI. Material y Métodos: Se completó un estudio de cohorte prospectivo. Se realizó una evaluación clínica, y de la audición con timpanometría, reflejo estapedial, audiometría tonal y logoaudiometría. Resultados: Treinta pacientes completaron el estudio; edad media de 22 años (rango 6-63 años). El 67% tenía una OI tipo I. Nueve pacientes (30%) tuvieron hipoacusia (15/60 oídos). De estos, seis tenían hipoacusia bilateral. De los 15 oídos afectados, seis tenían hipoacusia de conducción, cinco hipoacusia neurosensorial y cuatro hipoacusia mixta. Los pacientes con hipoacusia eran mayores que los pacientes con audición conservada. Sólo un paciente pediátrico desarrolló hipoacusia. De los oídos sin hipoacusia, el 13% tenía un reflejo estapedial ausente. Conclusiones: En este grupo de pacientes con OI, el 30% tenía hipoacusia. Además, el 13% de los oídos con audición normal no tenía reflejo acústico estapedial. Los pacientes con OI deben ser monitoreados para detectar hipoacusia.

Sensorineural hearing loss in the acute phase of a single episode of acute otitis media / Perda auditiva neurossensorial no início de um único episódio de otite média aguda

Abstract Introduction: Acute otitis media is a disease with high global prevalence, that can lead to several acute complications and auditory sequelae. Data regarding the auditory evaluation in the acute phase of acute otitis media are scarce. Objective: To evaluate the main audiometric changes (air and bone conduction thresholds) in the initial phase of an acute otitis media episode. Methods: A case-control study was performed. Patients diagnosed with acute otitis media with less than 7 days of evolution in relation to the complaint onset were selected, and healthy volunteers were selected as controls. The acute otitis media and control groups were submitted to pure tone and vocal audiometry. Results: The acute otitis media group included a total of 27 patients (30 ears). Hearing loss was present in 90.0% of the ears with acute otitis media, with conductive loss in 14 (46.67%) and mixed loss in 13 (43.33%). Both the air and bone conduction thresholds obtained with the tonal audiometry in the acute otitis media group were significantly worse than the controls at all tested frequencies (p< 0.05). In patients with acute otitis media, we observed that the thresholds for frequency >1 kHz (bone conduction) and 3 kHz (air conduction) were significantly worse in patients with tinnitus compared to patients without tinnitus. Conclusion: During the first 7 days of evolution after the onset of an isolated episode of acute otitis media, we observed significant increases in bone and air thresholds at all frequencies, especially >2 kHz, compared to healthy ears.

Resumo Introdução: A otite média aguda é uma doença de elevada incidência global, que pode levar a diversas complicações agudas e sequelas auditivas. Dados referentes à avaliação auditiva na fase aguda da otite média aguda são escassos. Objetivo: Avaliar as principais alterações audiométricas (limiares em via aérea e óssea) na fase inicial de um episódio de otite média aguda. Método: Realizou-se estudo de caso-controle. Selecionamos pacientes com diagnóstico de otite média aguda, com menos de sete dias de evolução em relação ao início das queixas, e voluntários saudáveis foram selecionados como controles. Os grupos otite média aguda e controle foram submetidos a audiometria tonal, vocal e audiometria. Resultados: O grupo otite média aguda incluiu 27 pacientes (30 orelhas). Observou-se presença de perda auditiva em 90% das orelhas com otite média aguda, condutiva em 14 (46,67%) e mista em 13 (43,33%). Tanto os limiares auditivos por via aérea quanto os limiares por via óssea obtidos com audiometria tonal do grupo otite média aguda eram significativamente piores em relação aos controles, em todas as frequências testadas (p < 0,05). Em pacientes com otite média aguda, observamos que os limiares das frequências acima de 1 kHz (via óssea) e 3 kHz (via aérea) eram significantemente piores entre pacientes com zumbido em comparação a pacientes sem zumbido. Conclusão: Nos primeiros sete dias de evolução do quadro inicial de um episódio isolado de otite média aguda, observamos aumentos significativos dos limiares ósseos e aéreos em todas as frequências, principalmente nas acima de 2 kHz, em comparação a orelhas sadias.
