ABSTRACT INTRODUCTION: Tinnitus is a multifactorial condition and its prevalence has increased on the past decades. The worldwide progressive increase of the use of cell phones has exposed the peripheral auditory pathways to a higher dose of electromagnetic radiofrequency radiation (EMRFR). Some tinnitus patients report that the abusive use of mobiles, especially when repeated in the same ear, might worsen ipsilateral tinnitus. OBJECTIVE: The aim of this study was to evaluate the available evidence about the possible causal association between tinnitus and exposure to electromagnetic waves. METHODS: A literature review was performed searching for the following keywords: tinnitus, electromagnetic field, mobile phones, radio frequency, and electromagnetic hypersensitivity. We selected 165 articles that were considered clinically relevant in at least one of the subjects. RESULTS: EMRFR can penetrate exposed tissues and safety exposure levels have been established. These waves provoke proved thermogenic effects and potential biological and genotoxic effects. Some individuals are more sensitive to electromagnetic exposure (electrosensitivity), and thus, present earlier symptoms. There may be a common pathophysiology between this electrosensitivity and tinnitus. CONCLUSION: There are already reasonable evidences to suggest caution for using mobile phones to prevent auditory damage and the onset or worsening of tinnitus.
RESUMO INTRODUÇÃO: Zumbido é uma condição multifatorial cuja prevalência vem aumentando nas últimas décadas. Em todo o mundo, o aumento progressivo do uso de telefones celulares tem exposto as orelhas a uma maior carga de radiação eletromagnética de radiofrequência (REM-RF). Alguns pacientes com zumbido referem que o uso excessivo do telefone celular, especialmente quando sempre na mesma orelha, é um fator de piora do zumbido ipsilateral. OBJETIVO: O objetivo deste trabalho foi avaliar as evidências disponíveis sobre a possível associação causal entre zumbido e exposição a ondas eletromagnéticas. MÉTODO: Foi realizada uma revisão de literatura com palavras-chave como: tinnitus, electromagnectic field, cellular phone, radiofrequency, electromagnectic hypersensitivity. Foram selecionados 165 artigos com maior relevância clínica em pelo menos um dos assuntos. RESULTADOS: As REM-RF podem penetrar tecidos expostos e existem níveis seguros de exposição. Apresentam efeitos termogênicos comprovados e potenciais efeitos biológicos e genotóxicos. Alguns indivíduos são mais sensíveis à exposição eletromagnética (eletrossensibilidade) e, portanto, adquirem sintomas precocemente. A fisiopatologia da eletrossensibilidade pode ser semelhante à do zumbido. CONCLUSÃO: Consideramos que há evidências suficientes que sugerem maior cautela para o uso desses aparelhos e assim prevenir lesões na via auditiva e o aparecimento/agravamento do zumbido.

Introdução: O zumbido é a percepção do som sem a presença de estímulo sonoro externo, sendo negativamente impactante para os indivíduos afetados. Já a prática de exercício físico pode exercer efeito positivo nesses sujeitos. Objetivo: Verificar o impacto do zumbido em idosos praticantes e não praticantes de exercício físico, considerando-se idade e gênero. Métodos: Nesta pesquisa transversal, quantitativa e comparativa, foram avaliados, por meio do Tinitus Handicap Inventory, 38 idosos com zumbido, divididos em dois grupos com 19 componentes cada, denominados: praticante (G1) e não praticante (G2) de exercício físico. Os dados foram analisados de forma estatística quantitativa. Resultados: Observou-se que o impacto do zumbido nos idosos do G1 foi menor. O gênero influenciou os achados na comparação intergrupos, e a idade exerceu influência somente no G1. Conclusão: O impacto do zumbido é menor nos idosos praticantes de atividade física, e a idade e o gênero influenciaram parcialmente os resultados obtidos.
Introduction: Tinnitus, the perception of sound in the absence of an external sound stimulus, has a negative impact on affected individuals. The practice of physical exercise can exert a positive effect on these subjects. Objective: To assess the impact of tinnitus on elderly practitioners and non-practitioners of physical activity, considering age and gender. Methods: In this cross-sectional, quantitative, and comparative study, 38 elderly subjects with tinnitus were evaluated by the Tinnitus Handicap Inventory after being divided into two groups with 19 subjects in each: practitioners (G1) and non-practitioners (G2) of physical exercise. The data were analyzed by quantitative statistical methods. Results: It was observed that the impact of tinnitus on G1 elderly subjects was lower. Gender influenced the results in the intergroup comparison that was carried out, but age had an influence only in G1. Conclusion: The impact of tinnitus was lower in elderly practitioners of physical activity, and the age and the gender partially influenced the results.

INTRODUCTION: For many years, excessive caffeine consumption has been touted as an aggravating factor for tinnitus. The pathophysiology behind this effect is probably related to the blockage of adenosine receptors by the action of caffeine on the central nervous system. OBJECTIVE: To evaluate the effects of reduction of coffee consumption on tinnitus sensation and to identify subgroups more prone to benefit from this therapeutic strategy. STUDY DESIGN: Prospective. METHODS: Twenty-six tinnitus patients who consumed at least 150 mL of coffee per day were selected. All were asked to reduce their coffee consumption. The Tinnitus Handicap Inventory (THI) questionnaire was completed by the patients before and after the reduction of coffee consumption, as well as a visual-analog scale (VAS) graduated from 1 to 10. RESULTS: THI and VAS scores were significantly reduced (p<0.05). In the subgroups less than 60 years old, bilateral tinnitus and daily coffee consumption between 150 and 300 mL showed a significantly greater reduction of THI and VAS scores. CONCLUSION: Patients under 60 years of age with bilateral tinnitus and daily coffee consumption between 150 and 300 mL are more prone to benefit from consumption reduction. Thirty-day observation periods may be helpful for a better therapeutical decision.

INTRODUÇÃO: O consumo abusivo de cafeína vem sendo descrito como fator de piora e causa do zumbido há muitos anos. A fisiopatologia deste efeito está provavelmente relacionada ao bloqueio dos receptores inibitórios adenosínicos pela cafeína no sistema nervoso central. OBJETIVO: Avaliar os efeitos da redução do consumo de cafeína na percepção do zumbido e identificar subgrupos de pacientes mais propensos a benefícios com esta proposta. Tipo de estudo: prospectivo. MÉTODO: Selecionados 26 pacientes com zumbido neurossensorial e consumo diário superior a 150 mL de café. Os efeitos da redução do consumo foram avaliados através do Tinnitus Handicap Inventory (THI) e da escala visual-análoga (EVA). RESULTADOS: Houve redução estatisticamente significativa (p < 0,05) nos escores do THI e EVA. Nos subgrupos com idade inferior a 60 anos, zumbido bilateral e consumo diário de café entre 150 e 300 mL apresentaram maior redução dos escores THI e EVA. CONCLUSÃO: Em pacientes com idade inferior a 60 anos, zumbido bilateral e consumo diário de café entre 150 e 300 mL apresentaram benefícios com a redução no consumo diário de cafeína. Períodos observacionais de 30 dias podem ser úteis para a decisão terapêutica. .

BACKGROUND: High sodium salicylate doses can cause reversible hearing loss and tinnitus, possibly due to reduced outer hair cell electromotility. Sodium salicylate is known to alter outer hair cell structure and function. This study determined the reversibility and cochlear recovery time after administration of an ototoxic sodium salicylate dose to guinea pigs with normal cochlear function. STUDY DESIGN: Prospective experimental investigation. METHODS: All animals received a single 500 mg sodium salicylate dose, but with different durations of action. Function was evaluated before drug administration and immediately before sacrifice. Cochleae were processed and viewed using scanning electron microscopy. RESULTS: Changes in outer hair cell function were observed to be present 2 hours after drug administration, with recovery of normal anatomy beginning after 24 hours. Subsequently, derangement and distortion of cilia reduced, with effects predominantly in row three. At 168 hours, cilia were near-normal but with mild distortions which interfered with normal cochlear physiology. CONCLUSIONS: Ciliary changes persisted for up to 168 hours after ototoxic sodium salicylate administration.

UNLABELLED: Pop-rock musicians are at risk of developing hearing loss and other symptoms related to amplified music. AIM: The aim of the present study was to assess the satisfaction provided by the use of hearing protection in pop-rock musicians. STUDY DESIGN: Contemporary cohort study. MATERIALS AND METHODS: A study of 23 male pop-rock musicians, aged between 25 to 45 years. After audiological evaluation (pure tone audiometry, middle ear analysis, TEOAE and DPOAE) hearing protective devices were provided to be used for three months. After that musicians answered a satisfaction assessment questionnaire. RESULTS: The prevalence of hearing loss was of 21.7%. The most common complaints about the hearing protectors were: autophonia, pressure in the ears, interference in high frequencies perception and full time use of the hearing protector during concerts. There was a positive correlation between a reduction in tinnitus after the use of the HPD with the following complaints: tinnitus after beginning the career (p= 0.044), discomfort with the sound intensity in the work place (p= 0.009) and intolerance to loud sound (p= 0.029). CONCLUSIONS: There was a high prevalence of hearing loss and a positive tendency towards the use of the ear protector device among the sample population.

Músicos de pop-rock apresentam risco de perda auditiva e outros efeitos associados à exposição à música amplificada. OBJETIVO: Avaliar o uso de protetores auditivos em músicos de bandas de pop-rock. Forma de Estudo: Coorte contemporânea. MATERIAL E MÉTODO: Estudo com 23 músicos de pop-rock, do sexo masculino, com idades entre 25 e 45 anos. Após a realização de audiometria tonal, imitância acústica, EOAET e EOAPD, os músicos receberam um protetor auditivo utilizado por três meses e, após esse período, preencheram a um questionário sobre a satisfação em relação ao uso. RESULTADOS: A prevalência de perdas auditivas foi de 21,7 por cento. As principais queixas durante o uso de protetor foram: voz abafada, pressão no ouvido, interferência na percepção dos sons de frequências altas, ao uso do protetor em tempo integral nas apresentações. Houve correlação positiva entre a percepção da diminuição do zumbido após o uso do protetor auditivo com as seguintes queixas: presença de zumbido após iniciar a profissão (p= 0,044), incômodo com a intensidade sonora em seu local de trabalho (p= 0,009) e intolerância a som forte (p= 0,029). CONCLUSÕES: Houve uma elevada prevalência de perdas auditivas e uma tendência favorável à aceitação do protetor auditivo na população estudada.

In order to investigate whether myofascial trigger points can modulate tinnitus, as well as the association between tinnitus and myofascial trigger points, 94 individuals with and 94 without tinnitus, matched by age and gender, were analyzed by means of bilateral digital pressure of 9 muscles. Temporary modulation of tinnitus was frequently observed (55.9%) during digital pressure, mainly in the masseter. The rate of tinnitus modulation was significantly higher on the same side of the myofascial trigger point subject to examination in 6 out of 9 muscles. An association between tinnitus and the presence of myofascial trigger points was observed (p < 0.001), as well as a laterality association between the ear with the worst tinnitus and the side of the body with more myofascial trigger points (p < 0.001). Thus, this relationship could be explained not only by somatosensory-auditory system interactions but also by the influence of the sympathetic system.

This study evaluated the interference of tinnitus on the quality of life for noise-exposed workers enrolled in a hearing conservation program. Noise measurements, a questionnaire, a Brazilian version of the Tinnitus Handicap Inventory (THI), and pure-tone audiometry were conducted with 52 participants (mean age, 29 years) who suffered from tinnitus. THI results indicated that tinnitus had the greatest influence in the functional scale (54%). Significant correlations (p < .05) were observed between the periodicity of tinnitus and noise exposure level; degree of tinnitus and exposure to chemicals; total THI score and the scores of the catastrophic, emotional, and functional scales; score of the emotional scale and the functional scale; and results of the THI and the general state of health. An evaluation of tinnitus and its impact could benefit tinnitus sufferers in the workplace.

Introducción: El tinnitus neurosensorial está correlacionado con numerosas patologías del oído interno y de su vía central y que pueden originarse en cualquier nivel de ésta; sin embargo todas estas noxas pueden manifestarse igual en corteza auditiva, como una sensación auditiva sin mediar un estímulo acústico externo, de tal manera que este mensajero común deben ser los neurotransmisores. Se han descrito dos en la vía auditiva aferente: el glutamato que es excitatorio y el GABA que es inhibitorio. Numerosos estudios revelan que el tinnitus neurosensorial se produciría por un desbalance de estos dos neurotransmisores con predominio excitatorio. El acamprosato es un fármaco usado en el alcoholismo que actuaría modulando el equilibrio GABA-glutamato. Existe un sólo estudio publicado con el uso del acamprosato en el tinnitus con una mejoría o disminución de su intensidad en 80 por ciento o más de los casos. Objetivos: Conocer la real utilidad del fármaco pues en este estudio, arriba mencionado, la evaluación fue sólo subjetiva y sin seguimiento. Material y Método: Fueron estudiados 20 pacientes tratados por un mes efectuándose tinnitumetría, evaluación psicoemocional (THI) y seguimiento. Resultados: De los 20 pacientes, en dos desapareció el tinnitus, en seis bajaron los niveles de la tinnitumetría en 5 dBo más con mejoría del THI en 50 por ciento o más y en doce pacientes la mejoría fue menor o ninguna. Conclusiones: Sería posible modular los neurotransmisores de la vía auditiva aferente con éxito, en aquellos pacientes con tinnitus severo. Es un estudio original con un respaldo fisiopatológico que abre nuevas perspectivas terapéuticas.

OBJECTIVE: To establish whether the oral administration of moderate doses of prednisone reduces refractory vertigo in Ménière's disease. STUDY DESIGN: Blinded, randomized, controlled trial. SETTING: Tertiary referral center. PATIENTS: Patients with Ménière's disease with limited vertigo control (Class C) and severe disability (Scale 3). INTERVENTIONS: Two groups (n = 8 per group) were treated orally with either diphenidol (25 mg/d) plus acetazolamide (250 mg/48 h) (control group), or the same treatment plus prednisone (0.35 mg/kg) daily for 18 weeks (prednisone group). MAIN OUTCOME MEASURES: The variables evaluated were the frequency and duration of vertigo, tinnitus, aural fullness, and audiographic parameters. The clinical surveillance was performed for 12 months after prednisone withdrawal. RESULTS: The frequency and duration of vertigo episodes were reduced by 50% and 30%, respectively, by prednisone treatment. Prednisone-treated patients manifested a significant reduction in tinnitus. No changes were observed in aural fullness or hearing. No metabolic or infectious disorders were observed. CONCLUSION: Oral prednisone helps to control refractory vertigo in Ménière's disease. These preliminary data suggest that prednisone can be a good noninvasive antivertigo management regimen for these patients.
