RESUMO Objetivo: revisar a literatura disponível sobre a relação entre alterações auditivas e deficiência da biotinidase. Métodos: a busca foi realizada entre outubro de 2018 e agosto de 2021, nas bases de dados: ELSEVIER, MEDLINE, SciELO, LILACS. Utilizaram-se descritores em português, inglês e espanhol, além das ferramentas PRISMA para seleção dos artigos e STROBE para análise dos mesmos. Revisão da Literatura: foram selecionados artigos publicados entre 1983 e 2020 que respondiam à pergunta norteadora da pesquisa. Foram incluídos estudos observacionais, estudos de série de casos e relatos de caso, e excluídos os artigos sem descrição dos métodos utilizados, realizados pelo mesmo autor e com a mesma amostra. A estratégia de busca inicial identificou 152 artigos. Após aplicados os critérios de inclusão e exclusão, 14 artigos foram incluídos na presente revisão. Conclusão: a presença de biotina foi frequentemente associada à gênese das vias auditivas. Foi observada uma relação sugerida pela literatura entre deficiência da biotinidase e alterações auditivas.

ABSTRACT Purpose: to review the available literature on the relationship between hearing disorders and Biotinidase deficiency. Methods: a literature search carried out between October 2018 and August 2021, on the following databases: ELSEVIER, MEDLINE, SciELO, LILACS. Descriptors were used in English, Portuguese, and Spanish. PRISMA tools were used to select the articles and STROBE was used to analyze them. Literature Review: the selected articles were published between 1983 and 2020 and answered the guiding question of the research. Observational studies, case series studies, and case reports were included. Articles without a methodology description, or carried out by the same author and with the same sample were excluded. The initial search strategy identified 152 articles. After applying the inclusion and exclusion criteria, 14 articles were selected for this review. Conclusion: the presence of Biotin was often associated with auditory pathways origins. The literature suggested a relationship between Biotinidase deficiency and hearing disorders.

Abstract Introduction Research with tinnitus patients presenting with hearing loss and normal hearing subjects have verified that tinnitus interferes with auditory processing. One treatment option for this symptom consists of tinnitus habituation therapy. Objective To determine the influence of tinnitus habituation therapy on auditory abilities, on the self-perception of tinnitus regarding loudness and discomfort, and its impact on the quality of life. Methods A quasi-experimental study was conducted with 19 individuals with tinnitus. Audiological tinnitus and auditory processing evaluations were performed. Subsequently, the volunteers underwent tinnitus habituation therapy for 6 months. Ultimately, all of the individuals were reevaluated. Results A statistically significant reduction in tinnitus self-perception was observed in relation to loudness, discomfort, and its impact on the quality of life (p = 0.001, 0.001, 0.023, respectively). However, the influence of tinnitus habituation therapy on auditory abilities was not verified. Conclusion Tinnitus habituation therapy was effective in reducing the self-perception of tinnitus loudness and discomfort, as well as the impact of the symptom on the quality of life. However, these factors did not improve the auditory processing skills in tinnitus patients.

RESUMO Objetivo: analisar o perfil das teleconsultorias de fonoaudiologia realizadas em serviço público de telessaúde de larga escala em Minas Gerais. Método: foram analisadas todas as teleconsultorias consecutivas de fonoaudiologia realizadas de fevereiro de 2011 a maio de 2014. As teleconsultorias foram agrupadas de acordo com tipo de dúvida, profissional solicitante e área de atuação fonoaudiológica. Resultados: as 259 teleconsultorias realizadas no período do estudo foram originadas de 81 municípios. A maior demanda de teleconsultorias foi dos próprios fonoaudiólogos (64,5%), seguidos de enfermeiros (27,0%) e médicos (5,0%). A maior parte das dúvidas eram assistenciais (81%), sendo que, destas, 35% eram para auxílio na definição diagnóstica e 65% para discussão de procedimentos e sugestão de condutas terapêuticas. Esta proporção foi semelhante, independente da formação do profissional solicitante: fonoaudiólogo e não fonoaudiólogo (65,7% vs. 64,9%, p=1,00). A maioria das dúvidas estava relacionada à área da linguagem (47%) e à motricidade oral (29%), seguidas de voz (20%), audiologia (18%), disfagia (10%) e saúde pública (3%). Conclusão: neste estudo, foi observado que a maioria das dúvidas para o serviço de teleconsultorias em fonoaudiologia estavam relacionadas à área da linguagem, mas há demanda em todas as áreas de abrangência da profissão. Embora o uso da teleconsultoria em fonoaudiologia seja ainda incipiente, observa-se grande potencial de utilização deste instrumento na prática clínica.

ABSTRACT Purpose: to analyze the profile of Speech, Language and Hearing Sciences teleconsultations of a large scale public telehealth service in Minas Gerais, Brazil. Methods: all Speech-Language Pathology teleconsultations performed from February 2011 to May 2014 were assessed and classified according to the type of questions, professional who sent the solicitation and the speech-language pathologist area of expertise. Results: the 259 teleconsultations performed during the study period were originated from 81 cities. The majority of the solicitations were originated from speech-language pathologists (64.5%), followed by nurses (27.0%) and physicians (5.0%), and were related to patients' assistance (81%). Among these, 35% were about diagnosis and 65% about discussion of procedures and therapeutic approaches. There was no difference with regards to the type of solicitation and healthcare practitioner, whether speech-language pathologist or not (65.7% vs. 64.9%, p=1.00). The majority of the questions were about language (47%), followed by oral motor functions (29%), voice (20%), audiology (18%), dysphagia (10%) and public health (3%). Conclusion: in this study, the majority of the solicitations to a Speech, Language and Hearing Sciences teleconsultation service were about language, although there was demand for all fields. Although the use of teleconsultations in Speech-Language Pathology, is still in its early stages there is great potential for using this tool in clinical practice.
