- 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.
- Effects of a vestibular rehabilitation program on workers in the working environment: a pilot study(2018) LONGO, Isadora Altero; NUNES, Ariane Diane Morais; ROCHA, Clayton Henrique; BRANCO, Fabiana Mara; MOREIRA, Renata Rodrigues; NEVES-LOBO, Ivone Ferreira; CASAROTTO, Raquel Aparecida; SAMELLI, Alessandra GiannellaABSTRACT Objective: to verify the effect of a vestibular rehabilitation program on workers with dizziness from the Division of Nutrition and Dietetics at a University Hospital. Methods: a total of 13 employees between 42 and 65 years of age participated, of whom, 1 was male, and 12, females. They were evaluated before and after the vestibular rehabilitation program using the Dizziness Handicap Inventory, Work Ability Index and Visual Analog Scale. The program was conducted in groups at the workplace. Statistical analysis was performed using the analysis of variance test for paired factors and the chi-square test. Results: in the pre- and post-vestibular rehabilitation comparison, significant differences were found in the Dizziness Handicap Inventory and Visual Analogue Scale scores. In the qualitative analysis of the Work Ability Index, an increase was observed in the number of workers who considered their ability to work to have improved. Conclusion: vestibular rehabilitation conducted in groups and in the working environment was effective in improving dizziness complaint in workers at the Division of Nutrition and Dietetics. It is believed that the positive experience of this program may be extended to other areas.
