“…A retrospective cohort analysis in Canada showed that there is a significant improvement in expressive communication in hearing-impaired children after the fitting of hearing aid. [ 11 ] Another study evaluates the improvement in deaf children's expressive and receptive language skills post-hearing aid fitting showed an inverse correlation with age of diagnosis. [ 12 ] Meaning early diagnosis and fitting of hearing aid is associated with better outcome and higher language skills.…”

Rationale:Mitochondrial DNA mutations have been associated with many maternal inherited diseases. A1555G mutation in mtDNA effects the gene code for rRNA, resulting in the structural change of human ribosome rending it susceptible to binding of the common antibiotic, aminoglycosides. Such mutation has linked with non-syndromic hearing loss and is one of the most common mtDNA mutations in Asian populations.Patient concerns:A 50-year-old Taiwanese female visited our neurology department with concern for multiple members with hearing loss in her family, including herself.Diagnoses:Physical examination findings were not significant besides hearing loss and brain MRI did not reveal any lesions. BAEP confirmed bilateral peripheral sensory deficit. Given the multiple cases of hearing loss in the family, a genetic cause was suspected. Using PCR and sequences chromatogram technique we have identified A1555G mutation on her mtDNA affecting region codes for 12S rRNA. Additionally, we observed severe speech disorder in two young family members with the onset of hearing loss began in their early childhood.Interventions:The patient declined any form of intervention at the time for personal reasons.Outcomes:The patient was satisfied with the diagnosis, her and her families are continuously followed by our neurology department.Lessons:We report on a family with mtDNA mutation hearing loss that is related to exposure to aminoglycosides. Children with such mutation are at high risk for impaired linguistic function. Early identification and intervention with cochlear implant should be considered.

“…Over the last decade, research has found positive results in speech and language development from early intervention programs aimed at hearing-impaired infants when the intervention takes place from their first year of life. These surveys have confirmed the importance of fitting amplification to ensure audibility of speech sounds as one of the conditions required for speech development in hearing-impaired children (1)(2)(3)(4)(5)(6) .…”

RESUMO Objetivo Comparar valores do índice de inteligibilidade de fala amplificado, para diferentes entradas de sinal de fala (75, 65 e 55 dBNPS), gerados no processo de verificação dos aparelhos de amplificação sonora, nos diferentes graus e configurações de perdas auditiva. Métodos Foram selecionadas 41 crianças com idades entre 3 e 80 meses, totalizando 78 orelhas (quatro orelhas foram excluídas). As perdas auditivas foram classificadas conforme grupos de audibilidade e intervalos do índice de inteligibilidade de fala. Foram analisados 234 valores do índice de inteligibilidade de fala para os estímulos de fala e estes foram também analisados, em relação aos grupos e intervalos de audibilidade. Resultados Os grupos de audibilidade se deslocaram entre os intervalos do índice de inteligibilidade de fala, indicando a variação, conforme o nível de apresentação do sinal de entrada. Duas equações foram geradas para prever valores do índice de inteligibilidade de fala a partir do valor deste índice para o sinal de entrada de 65. Conclusão Menores níveis de pressão sonora do estímulo de fala produzem menores índices de inteligibilidade de fala. Esta diferença é mais acentuada nos deficientes auditivos, que apresentam valores do índice de inteligibilidade de fala de 65 entre 36% e 55%.
