RESUMO
PURPOSE OF REVIEW: To review the literature on the clinical characteristics of the symptoms other than headache that occurs during a migraine attack in childhood and adolescence. RECENT FINDINGS: Premonitory symptoms (42-67%) and postdrome phase (82%) are frequent. The most frequent auras were visual. There was no association between age or sex and the occurrence of auras. Cranial autonomic symptoms are also frequent (40-70%) and are most often bilateral. Most studies suggest that age is not associated with the frequency of nausea, vomiting, photophobia, and phonophobia. Cephalic cutaneous allodynia (15-37%) and osmophobia (20-53%) are common symptoms in children with migraine. Osmophobia has low sensitivity and high specificity for the diagnosis of migraine and is associated with the severity of the migraine. Migraine is a complex disease, and although headache is its best-known symptom, other symptoms also occur frequently during migraine attacks in children and adolescents.

BACKGROUND: Vestibular-evoked myogenic potentials (VEMPs) are commonly used clinical assessments for patients with complaints of dizziness. However, relatively high air-conducted stimuli are required to elicit the VEMP, and ultimately may compromise safe noise exposure limits. Recently, research has reported the potential for noise-induced hearing loss (NIHL) from VEMP stimulus exposure through studies of reduced otoacoustic emission levels after VEMP testing, as well as a recent case study showing permanent sensorineural hearing loss associated with VEMP exposure. PURPOSE: The purpose of this report is to review the potential for hazardous noise exposure from VEMP stimuli and to suggest clinical parameters for safe VEMP testing. RESEARCH DESIGN: Literature review with presentation of clinical guidelines and a clinical tool for estimating noise exposure. RESULTS: The literature surrounding VEMP stimulus-induced hearing loss is reviewed, including several cases of overexposure. The article then presents a clinical calculation tool for the estimation of a patient's safe noise exposure from VEMP stimuli, considering stimulus parameters, and includes a discussion of how varying stimulus parameters affect a patient's noise exposure. Finally, recommendations are provided for recognizing and managing specific patient populations who may be at higher risk for NIHL from VEMP stimulus exposure. A sample protocol is provided that allows for safe noise exposure. CONCLUSIONS: VEMP stimuli have the potential to cause NIHL due to high sound exposure levels. However, with proper safety protocols in place, clinicians may reduce or eliminate this risk to their patients. Use of the tools provided, including the noise exposure calculation tool and sample protocols, may help clinicians to understand and ensure safe use of VEMP stimuli.

INTRODUCTION: Hyperacusis can be defined as a manifestation of an increased of central auditory pathways gain and can be considered a pre-tinnitus state. In some cases tinnitus can be caused by such increased gain. AIM: To evaluate the prevalence of hyperacusis in patients with tinnitus and its relation to the annoyance of tinnitus. MATERIALS AND METHODS: Retrospective study with patients from the neurotology service complaining of tinnitus in the first consultation were submitted to clinical evaluation, a questionnaire and audiological evaluation of tinnitus and hyperacusis. The degree of annoyance of tinnitus and hyperacusis was measured using a visual analog scale. RESULTS: We analyzed medical records of 309 patients, 169 (54.7%) females and 140 (45.3%) males. The mean age was 53 years. The median degree of tinnitus annoyance was 7. Hyperacusis was present in 57 (18.4%) patients, with a median degree of 5. The degree of annoyance due to tinnitus patients with hyperacusis was similar to that of patients without hyperacusis. CONCLUSION: Hyperacusis was present in 18.4% of patients with tinnitus. The degree of annoyance due to tinnitus had no correlation with the presence of hyperacusis.

Introdução: A hiperacusia pode ser definida como uma manifestação de ganho central aumentado das vias auditivas, compreendida como um estado pré-zumbido. Em alguns casos, o zumbido pode ser secundário a esse ganho aumentado. Objetivo: Avaliar a prevalência da hiperacusia em pacientes com zumbido e sua associação com o incômodo do zumbido. Materiais e métodos: Estudo retrospectivo envolvendo pacientes do ambulatório de otoneurologia com queixa principal de zumbido que foram submetidos a avaliação clínica, audiológica e a questionário de avaliação da hiperacusia e do zumbido. O grau de incômodo da hiperacusia e do zumbido foi classificado utilizando a Escala Visual Analógica. Resultados: Foram analisados prontuários de 309 pacientes, 169 (54,7%) do sexo feminino e 140 (45,3%) do sexo masculino, com idade média de 53 anos. O grau de incômodo do zumbido apresentou mediana de sete. A hiperacusia esteve presente em 57 (18,4%) pacientes, com mediana de grau de incômodo de cinco. O grau de incômodo pelo zumbido nos pacientes com hiperacusia foi semelhante ao dos pacientes sem hiperacusia. Conclusão: A hiperacusia esteve presente em 18,4% dos pacientes com zumbido. O grau de incômodo do zumbido não teve correlação com a presença da hiperacusia. .

Hyperacusis is mainly a consequence of the noise level in the twenty-first century, owing to dramatic changes in people's lifestyles. Of every 100 people with otological complaints (e.g., tinnitus and hyperacusis), 20 are affected by hyperacusis. Because of its high incidence, this symptom has long been the subject of investigation. Nine patients (eight female, one male) with sensorineural tinnitus voluntarily participated in this study. Among the evaluated patients, three were between 25 and 40 years of age and six were between 41 and 60 years. The patients did not report a history of acoustic trauma, use of drugs, or otological diseases. The duration of complaints at the time the study began varied from 3 months to 8 years. The patients answered a questionnaire, submitted to an ear, nose, and throat examination, and were evaluated by pure-tone and speech audiometry and otoacoustic emissions and laboratory tests. In all patients, ear, nose, and throat assessments and audiological tests were within the normal ranges. Of the nine subjects in our study, 100% had tinnitus, and 89% (n = 8) had hyperacusis as an associated symptom. Six subjects (67%) had severe tinnitus; among them, four had moderate hyperacusis, one had severe hyperacusis, and one was not affected by hyperacusis. In two subjects (22%) with moderate tinnitus, one had moderate hyperacusis and the other referred severe symptoms. Another patient (11%) reported mild tinnitus and mild hyperacusis. No patient classified his or her tinnitus as disabling. The findings of the present study led us to conclude that the most affected age range of patients with tinnitus and hyperacusis was 41-60 years and that women are affected significantly more often than men. Tinnitus preceded hyperacusis as a complaint in 78% of the subjects. Hyperacusis was present in eight (89%) of the patients. There was no direct correlation between the severity of tinnitus and of hyperacusis, although we noticed that the discomfort of tinnitus was generally perceived as equal to or worse than that of hyperacusis.
