The results suggest that the use of tinnitus therapy sounds delivered through a CI can be acceptable and provides relief for some tinnitus sufferers.
TEMA: Biossegurança na atuação audiológica. OBJETIVO: rever as medidas de precaução-padrão na literatura para o controle de infecção na audiologia. As medidas de biossegurança sugeridas para diversos profissionais de saúde foram adaptadas para as atividades inerentes à prática audiológica no Serviço de Audiologia do Hospital das Clínicas da UFMG. CONCLUSÃO: as medidas de precaução-padrão apresentadas podem ser consideradas e viabilizadas nas diversas instituições, hospitais ou clínicas, nas quais a atuação fonoaudiológica é cada vez mais presente e, por conseguinte, impele medidas de precauções específicas à natureza dos exames audiológicos.
The moderate ingestion of coffee was not shown to interfere in the results of the vestibular test. Considering that it is recommended that the patient be calm to be submitted to the vestibular test and that the half-life of the caffeine is only six hours, we suggest that the orientation of complete and abrupt drinking coffee suspension of moderate dose before the vestibular test for the individuals used to daily drinking coffee be reevaluated.
Exi st controversy about the interference of the caffeine in the vestibular test. Coffee is the richest source of caffeine. While in some services, the patients were orient to suspend the ingestion of caffeine 24 to 48 hours before the vestibular test, other not consider the suspension of this drink necessary. Aim: To evaluate the effect of caffeine in the vestibular test result. Study design: clinical with transversal cohort. Material and Method: Seccional and matched research. The vestibular test was performed twice in the same patient, with five days interval between the exams. In the first test, the patient did not drink coffee 24 hours before the exam; in the second, the patient drunk coffee as usual. All of the participants had clinical indication for vestibular test and were used to drinking coffee. Results: Nineteen women, medium age of 49,5 years, participated. The average coffee consumption was three cups per day. The complaints of anxiety and headache were associated with the submission to the vestibular test without coffee. The exams were not statistically different comparing the results of the tests performed with and without the coffee ingestion. Conclusion: The moderate ingestion of coffee was not shown to interfere in the results of the vestibular test. Considering that it is recommended that the patient be calm to be submitted to the vestibular test and that the half-life of the caffeine is only of six hours, we suggest that the orientation of complete and abrupt drinking coffee suspension of moderate dose before the vestibular test for the individuals used to daily drinking coffee be reevaluated.
It is well accepted among clinicians that maskers and hearing aids combined with counseling are generally helpful to tinnitus patients, but there are few controlled studies exploring the efficacy of maskers alone to decrease the prominence of tinnitus.We investigated the benefit of maskers for patients with chronic, bothersome tinnitus.Crossover single-participant design, where each participant served as their own control.18 adults with subjective, nonpulsatile, sensorineural tinnitus.Participants participated in two six-week trials: one with sound therapy and one without. No counseling was provided in either group. Masking devices were fit with sounds intended to reduce the tinnitus prominence.Participants rated tinnitus loudness, tinnitus annoyance, and acceptability of the background sounds using a numeric 0–100 interval scale and completed the Tinnitus Primary Functions Questionnaire (TPFQ).Three participants dropped out. On the total score of the TPFQ, 5 of 15 remaining participants (33%) showed a benefit. Using a derived score based on functions showing a handicap before the study, maskers benefit was observed in the areas of sleep (five of nine), hearing (three of eight), thoughts and emotions (three of four), and concentration (four of eight). The TPFQ and annoyance data complemented each other well.This study demonstrates the benefit of partial masking, encouraging patients to seek help from audiologists interested in providing support for tinnitus patients.
Introdução: a avaliação vestibular é realizada tradicionalmente por meio da prova calórica para avaliação do labirinto em indivíduos com tonturas, porém este exame não avalia toda a via vestibular. Os potenciais evocados miogênicos vestibulares (VEMP) consistem em um exame de rápida execução, considerado método de escolha para avaliação dos órgãos otolíticos e do nervo vestibular. Objetivo: analisar as respostas do exame VEMP cervical (cVEMP) e ocular (oVEMP) em indivíduos com doenças vestibulares e compará-las àquelas obtidas em indivíduos de mesma faixa etária e sexo sem queixas de tontura pregressas e atuais. Métodos: Estudo observacional, transversal e analítico. Os participantes foram divididos em dois grupos: grupo com tontura (GT), composto por indivíduos com diversas doenças vestibulares e o grupo sem queixa de tontura (GC). Ambos os grupos foram submetidos à meatoscopia, ao VEMP cervical e ocular. Resultados: A amostra foi composta por 45 indivíduos com a idade entre 23 e 68 anos, sendo 27 indivíduos do grupo GC e 18 do grupo GT. No exame cVEMP as latências, amplitudes, índice de assimetria e o índice de assimetria corrigido foram iguais no GT quando comparado com o GC. No exame oVEMP encontrou-se a amplitude esquerda maior e a latência N10 menor estatisticamente no grupo GT quando comparado ao grupo GC. Dentre as doenças do grupo GT os indivíduos com deiscência de canal superior tiveram valores maiores na amplitude esquerda, o que pode ter interferido nos resultados. Conclusão: Não foram evidenciadas diferenças nas respostas do cVEMP entre os grupos neste estudo. Encontrou-se aumento da amplitude esquerda e o valor menor da latência N10 direita no grupo com tontura na análise do exame oVEMP. Acredita-se que a heterogeneidade de doenças vestibulares no grupo com tontura e o reduzido número de participantes em ambos os grupos tenham contribuído para esse desfecho.
Purpose: to evaluate the effect of age on vestibular-ocular reflex gain through v-HIT. Methods: this was a cross-sectional, analytical, observational study conducted with 90 subjects without self-reported otoneurological alterations, who underwent v-HIT examination in order to evaluate semicircular canal gain and cephalic pulse velocity. Results: the age of the sample ranged from 20 to 83 years. It was decided that the sample be divided into three age groups to facilitate the analysis: 18 to 30 years; 31 to 59 years, and over 60 years old. A decrease in vestibular-ocular reflex gains of the right and posterior semicircular canals was observed with increasing age. The average semicircular canal gain was close to one and the velocities above 100º/s. Conclusion: the average gain of the semicircular canals is within the normality standards found in the literature. Only the posterior and right anterior semicircular canals showed reduced gain with increasing age. RESUMO Objetivo: avaliar o efeito da idade sobre o ganho do reflexo vestíbulo-ocular por meio do v-HIT. Métodos: estudo transversal, analítico, observacional, realizado com 90 indivíduos sem alterações otoneurológicas autorrelatadas, que foram submetidos ao exame v-HIT, com o intuito de avaliar o ganho dos canais semicirculares e a velocidade dos impulsos cefálicos. Resultados: a idade da amostra variou de 20 a 83 anos. Optou-se pela divisão em três faixas etárias para facilitar a análise: 18 a 30 anos; 31 a 59 anos e maior que 60 anos. Houve diminuição dos ganhos do reflexo vestíbulo-ocular dos canais semicirculares anterior direito e posteriores com o aumento da idade. As médias do ganho dos canais semicirculares foram próximas a 1 e as velocidades, acima de 100º/s. Conclusão: as médias do ganho dos canais semicirculares estiveram de acordo com os padrões de normalidade da literatura. Apenas os canais semicirculares posteriores e o anterior direito apresentaram redução do ganho com o aumento da idade.
