Objectives: Vestibular migraine is a neurological disorder characterized by the association of vertigo and headache, affecting up to 1% of the population. Among its differential diagnoses is endolymphatic hydrops. The aim of this study was to investigate the role of cervical vestibular-evoked myogenic potential and electrocochleography in the diagnosis of vestibular migraine., Method: Thirteen women with clinical diagnosis of vestibular migraine (mean age 44 years) and 13 healthy volunteers without auditory and/or vestibular complaints matched for sex and age were evaluated by performing hydrops examinations of cervical vestibular-evoked myogenic potential and electrocochleography., Results: The presence of vertigo and headache was reported by all members of the group with vestibular migraine, associated with symptoms such as nausea, photophobia, and phonophobia. Tinnitus was the most frequent auditory complaint. A significant increase in P1 and N1 latencies was observed in the test group. There was no significant difference in the occurrence of asymmetry and decreased amplitude of the cervical vestibular-evoked myogenic potential. Electrocochleography showed an increase in amplitude of the summation potential. The altered SP/AP ratio was double in the group with vestibular migration, without statistical significance., Conclusions: Changes in latency increase of cervical vestibular-evoked myogenic potential suggests a central lesion. Patients with vestibular migraine may present electrocochleography compatible with endolymphatic hydrops., Level of Evidence: Level 4., (Copyright © 2024 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Introduction: Chikungunya infection presents with distinct clinical features depending on the patient age group., Methods: Medical records of children with positive IgM for the chikungunya virus who were hospitalized in a pediatric ward in Fortaleza, Ceará, Brazil were analyzed., Results: Fourteen children with a median age of 4 months (36 days to 15 years) were included. All patients presented with fever persisting for an average of 5 days. The joints were involved in 6 (42.8%) children, and 8 (57.1%) children presented with bullous rash., Conclusions: Systemic involvement and atypical clinical manifestations characterize severe forms of chikungunya infection in children.
