Título: Reproducibility (test-retest) of vestibular evoked myogenic potential Autor(es): Oliveira, Aline Cabral de; Menezes, Pedro de Lemos; Pereira, Liliane Desgualdo Abstract: Introdução: Ainda não existe consenso quanto ao melhor estímulo acústico utilizado para a captação do potencial evocado miogênico vestibular (PEMV). Respostas amplas são observadas para estímulos de baixa frequência, porém estudos recentes ainda utilizam cliques. A reprodutibilidade dos traçados é um importante parâmetro de análise para observar a confiabilidade das respostas. Objetivo: Verificar a reprodutibilidade dos parâmetros ‘‘latência e amplitude das ondas p13 e n23’’ do PEMV para estímulos com diferentes frequências de estímulos do tipo tone burst, e definir a melhor frequência de teste. Método: Estudo de coorte-transversal. Captou-se PEMV em 156 orelhas, no músculo esternocleidomastóideo, com 100 estímulos do tipo tone burst nas frequências de 250, 500, 1000 e 2000 Hz e nível sonoro 95 dB NAn, registrados três vezes de cada lado. Resultados: Foram constatadas similaridades para latências de p13 e n23 do potencial estudado nos três momentos com estímulos tone burst em 250, 500, 1000 Hz, e diferenc¸as entre as captações desse potencial (P < 0.001) para a frequência de 2000 Hz. A análise da amplitude de p13 e n23 se mostrou semelhante, no teste-reteste, para todas as frequências analisadas. Conclusão: Existe reprodutibilidade das latências e amplitudes de p13 e n23 do PEMV para estímulos tone burst nas frequências de 250, 500 e 1000 Hz.

Título: Saúde auditiva e qualidade de vida em trabalhadores expostos a agrotóxicos Autor(es): Sena, Tereza Raquel Ribeiro de; Vargas, Marlizete Maldonado; Oliveira, Cristiane Costa da Cunha Abstract: The objective of this study was to determine the relationship between exposure to pesticides and the occurrence of hearing loss among rural workers of Povoado Colônia Treze, Lagarto, State of Sergipe, Brazil. A total of 351 adult workers aged 18 to 59 years were selected, with current or past work activity in rural areas, with or without use of pesticides. The hearing evaluation included a form to record air-borne tonal thresholds using normality criteria recommended by Merluzzi 1979. The instrument used for assessing the quality of life was the Brazilian version of Short Form 36 (SF-36). Statistical analysis was performed (chi-square c2, nonparametric Kruskal-Wallis test, Cramer’s V and Cohen’s d) with a significance level of 95% (p <0.05). The results related the use of pesticide with the degree of toxicity in the presence of hearing loss and indices of quality of life (p <0.001). This study proved that agricultural workers, users of pesticides showed the worst levels of quality of life when compared with those who have not handled them. The use of pesticides and their toxicity class interfered in a most striking way in the classification of hearing loss presented in this group and further studies are recommended to assess other impacts on this population.

Título: Categorização de pacientes adultos usuários de implante coclear do Hospital Universitário da Universidade Federal de Sergipe Autor(es): Nascimento, Ruanna Sotero Leão do; Costa, Francyelle Vieira da; Goes, Yasmim Dourado; Ferreira, Ícaro Silva Aguiar; Santos, Fabíola Andréa Andrade dos; Perez-Ramos, Isabel Cristina Sabatini Abstract: Introduction: Hearing loss (HL) is the most prevalent sensory deficit. Untreated hearing loss in adults can result in communication difficulties, leading to social isolation and a diminished quality of life. Adults with severe to profound sensorineural HL, who do not benefit from conventional hearing aids, are recommended to undergo cochlear implant (CI) surgery. Objectives: The aim of this study is to characterize the profile of adult patients undergoing cochlear implant surgery at the University Hospital of the Federal University of Sergipe. Methods: Data from medical records that met the selected criteria were included: sex, laterality, degree and type of hearing loss, period of language acquisition and etiology and functional gain research. Results A total of 11 medical records were analyzed, consisting of seven female subjects. Eight individuals received bilateral implants, all hearing losses of the sensorineural type, 15 HL of profound degree. In terms of language acquisition, 11 post-lingual HL, and regarding the etiology of hearing loss, most were idiopathic. The functional gain research indicated that five subjects had an average gain of 25 dBHL. Conclusion: The results highlight substantial hearing gain achieved by the population undergoing cochlear implantation.

Identificação e prevenção do risco de quedas com aplicação de dupla tarefa em idosos da comunidade

Título: Identificação e prevenção do risco de quedas com aplicação de dupla tarefa em idosos da comunidade Autor(es): Teixeira, Julianne Pitanga; Taguchi, Carlos Kazuo; Teixeira, Jacqueline Pitanga; Diniz, Luiz Fernando Lima; Santos, Letícia Cardoso dos; Silva, Allan Robert da Abstract: Objective: To identify risks for falling and analyze the results of an intervention proposal for the prevention of falls in the elderly with dual-task. Material and Methods: Fifty two volunteers from the Elderly Group in the Laranjeiras -SE, aged range 60 to 85 years, both genders, were submitted to the Dynamic Gait Index (DGI) and the Timed Up and Go (TUG) to determine the risk of falls. In the second step that spent five weeks, the intervention was offered to all volunteers based on the Cawthorne and Cooksey exercises that was choreographed with the music Whiskey a Go-Go and Xote das Meninas. In the third stage the participants were reevaluated with the same protocols used. It adopted the p ≤0.05 for statistical correlations. Results: Around 84.6% were female and 15.4% male; 41 volunteers presented bad performance in the TUG and 20 in the DGI. There was a tendency to correlate between age and TUG (p = 0,06), but there was no correlation between age and DGI (p = 0,26); there was a strong negative correlation between DGI and TUG (p=0,009351). Thirteen seniorswere reevaluated, twelve of them female and one male, aged from 60 to 80. The results of DGI and TUG after the program showed best scores, which means less risk to falls. Conclusion: The proposed intervention with a bimodal task in prevention decreased the falling risks and TUG showed worse performance in older volunteers.
