- Audiological characteristics in mucopolysaccharidosis: a systematic literature review(2019) CHIMELO, Flávia Teixeira; SILVA, Liliane Aparecida Fagundes; KIM, Chong Ae; MATAS, Carla GentileABSTRACT Purpose: to describe the audiological characteristics of patients with mucopolysaccharidosis. Methods: after formulating the research question, three databases were considered for the search (Science Direct, Virtual Health Library and Web of Science); the following descriptors were used: mucopolysaccharidoses, hearing loss, and audiology. Articles were included that were original and complete, presenting audiological evaluation data in patients with mucopolysaccharidosis. Each study was classified according to the degree of recommendation and the level of scientific evidence, based on the criteria established by the Oxford Center for Evidence-based Medicine, and the results obtained from the evaluations were analyzed. Results: of the 499 articles found, eight met the inclusion criteria. Pure tone audiometry and tympanometry were performed in all studies. The incidence of hearing loss in patients with MPS ranged from 54% to 100% of the cases, with conductive hearing loss corresponding to 30% and 58.33%, mixed hearing loss corresponding to 28.5% and 66.66% and sensorineural hearing loss corresponding to less than 14%. None of the studies described the responses of otoacoustic emissions and auditory evoked potentials. Conclusion: the prevalence of hearing loss among individuals with MPS is higher than 54% of the cases, of which conductive and mixed are predominant.
- Simetria das medidas timpanométricas e as respostas das emissões otoacústicas transientes em neonatos(2014) SILVA, Liliane Aparecida Fagundes; SILVA, Kilza de Arruda Lyra e; SANCHES, Seisse Gabriela Gandolfi; CARVALLO, Renata Mota Mamede deOBJETIVO: verificar a ocorrência de simetria maior ou igual à 70%, entre as orelhas, comparando os resultados da timpanometria nas frequências de 226 e 1000Hz com as respostas das emissões otoacústicas em neonatos. MÉTODOS: foram avaliados 39 neonatos, em média com 60 horas de vida, sendo 20 do sexo feminino e 19 do sexo masculino. Cada recém-nascido foi submetido à avaliação timpanométrica com as sondas de 226 e 1000 Hz, e avaliação das emissões otoacústicas transientes em ambas as orelhas. Os resultados foram submetidos a testes estatísticos. RESULTADOS: na análise da amostra pode-se observar ocorrência de simetria <70% nas respostas das emissões otoacústicas em 74,4% do total de neonatos. Por outro lado, na timpanometria, houve uma maior ocorrência de simetria ≥ 70%, tanto para sonda de 226 quanto para 1000Hz (76,9% e 84,6%, respectivamente). No que diz respeito ao gênero e orelha, as diferenças encontradas em cada teste não foram significantes, embora tenha sido observada maior amplitude de respostas de emissões otoacústicas na orelha direita. CONCLUSÃO: os resultados sugerem haver simetria no sistema auditivo em sua porção mais periférica, e início de assimetrias a partir da cóclea.
- Study of the neural plasticity in adults and older adults new hearing aid users(2020) SOUZA, Gabriela Valiengo de; MATAS, Carla Gentile; SILVA, Liliane Aparecida Fagundes; LOBO, Ivone Ferreira Neves; SAMELLI, Alessandra GiannellaABSTRACT Purpose: to monitor, with long-latency auditory evoked potentials, the plasticity of the central auditory pathways in adults and older adults, new users of hearing aids. Methods: a total of 15 adults and older adults, aged 55 to 85 years, participated in the research. They had a symmetric bilateral mild to moderate sensorineural hearing loss, without previous experience with any type of hearing aid. The long-latency auditory evoked potentials were conducted with and without amplification, at 60 and 75 dBnHL, with speech stimulus in a sound field, in two assessment moments: up to one week after fitting the hearing aid and after six months of its use. The Student’s t-test was used for statistical analysis, considering significant the p-value < 0.05. Results: responses with lower latency values were observed for the right ear in the second assessment. Comparing the first with the second assessment, both with and without the hearing aid, an increase in the amplitude of P2-N2 was observed, as well as an increase in the latency of the P2 component at the intensity of 75 dBnHL. No statistically significant differences were observed at the intensity of 60 dBnHL. Conclusion:the use of the hearing aid promoted the plasticity of the central auditory pathways, increasing the number of neurons responsive to the sound stimuli.
- Audiological and electrophysiological assessment of professional orchestral musicians(2020) SAMELLI, Alessandra Giannella; RABELO, Camila Maia; SILVA, Liliane Aparecida Fagundes; GONZAGA, Denise; SANTIAGO, Joyce Miranda; MAGLIARO, Fernanda Cristina Leite; MATAS, Carla GentileABSTRACT Purpose: to verify whether the frequent musical exposure can impair peripheral and central auditory pathway responses in professional orchestral musicians. Methods: 45 male individuals from 19 to 40 years old participated in the study. They were divided into two groups: one comprising 30 orchestral musicians who played strings or wind instruments, and another with 15 nonmusicians. The two groups were submitted to both conventional and high-frequency pure-tone audiometry, transient-evoked otoacoustic emissions, and frequency-following response. The results were subjected to descriptive and inferential statistical analysis, using the one-way ANOVA unmatched samples parametric test, with a 5% significance level. Results: no significant differences were observed between the hearing thresholds in both conventional and high-frequency audiometry and frequency-following response. However, there were statistically significant differences between transient-evoked otoacoustic emission responses, with lower responses to musicians in comparison to the nonmusician group. Conclusion: the results suggest that frequent musical exposure experienced by orchestral musicians can impair the cochlear hair cells’ function. Therefore, audiological monitoring is important to detect subclinical impairments.
- Effects of chemotherapy on the auditory system of children with cancer: a systematic literature review(2020) LOPES, Nila Berbardes; SILVA, Liliane Aparecida Fagundes; SAMELLI, Alessandra Giannella; MATAS, Carla GentileABSTRACT Purpose: to identify and analyze the effects of chemotherapy on the auditory system of children and/or adolescents with cancer treated with cisplatin and carboplatin, assessed through standardized audiological procedures. Methods: studies in Brazilian Portuguese and in English were searched for, as available in the databases Science Direct, PubMed, LILACS, BIREME, Embase, SciELO, Web of Science and Cochrane. The descriptors were: Hearing Loss, Audiology, Child Cancer, Chemotherapy, and Child. Articles with levels 1 and 2 of scientific evidence, published in the last 20 years (1997 to 2017), were considered, of which the audiological results were analyzed, as well as the prevalence of hearing loss in children with cancer undergoing chemotherapy. Results: 3,625 articles were found, of which only 23 were selected for analysis in the present review. Studies have shown a high incidence of sensorineural hearing loss and decrease or even loss of otoacoustic emissions in children and adolescents with cancer, even after the first dose of chemotherapy drugs, with high frequencies being the most affected. Conclusion: there is evidence that both carboplatin and especially cisplatin from the first doses may impair the hearing of children and adolescents, mainly affecting the cochlear function, thus, the importance of long-term audiological monitoring.
- Audiological profile of individuals with Cornelia de Lange syndrome: an integrative review(2022) SANTOS, Nayara Pereira; SILVA, Liliane Aparecida Fagundes; KIM, Chong Ae; MATAS, Carla GentileABSTRACT Purpose: to describe the audiological profile of patients with Cornelia de Lange syndrome (CdLS) in an integrative review of the literature. Methods: after developing the research question, articles were searched in six databases (EMBASE, ISI of Knowledge, LILACS, MEDLINE/PubMed, SciELO, and Scopus) and in sources of information (Google Scholar, OpenGrey, and ProQuest), with the following descriptors: audiology, hearing loss, deafness, hearing disorders, and Cornelia de Lange syndrome. This review was registered in Prospero under number CRD42020191481. National and international studies were considered for analysis, using the PECO acronym. The risk of bias in the studies was analyzed with Joanna Briggs Institute protocols. Then, the studies were described and analyzed. Results: of the 1,080 articles found, 12 met the inclusion criteria. Audiological results showed that individuals with CdLS can have hearing loss - conductive hearing losses were the most frequent impairments, corresponding to 49.20% of individuals with CdLS assessed, followed by sensorineural hearing losses (13.49%). The degrees of hearing loss ranged from mild to profound. Conclusion: individuals presented with CdLS often have hearing loss, mainly due to middle ear changes, with degrees ranging from mild to profound.
