Management of laryngopharyngeal reflux in Brazil: a national survey.

Introduction: Studies assessing the management of laryngopharyngeal reflux by otolaryngologists have reported an important heterogeneity regarding the definition, diagnosis, and treatment, which leads to discrepancies in the management of the patient. Information about the current knowledge and practices of Brazilian otolaryngologists in laryngopharyngeal reflux is lacking.

Objective: To investigate the trends in management of laryngopharyngeal reflux disease among Brazilian otolaryngologists.

Diagnostic assessment of patients with Meniere's disease through caloric testing and the video-head-impulse test.

Introduction: Meniere's disease is a labyrinth disease that usually presents with episodes of spontaneous vertigo associated with sensorineural hearing loss, tinnitus and ipsi- and unilateral aural fullness in most cases. Vestibular function tests, video-head-impulse test and the caloric test, are not specific for diagnosis of the disease, but may show alterations that help to evaluate the functional impairment.

Objective: To describe the results obtained at the caloric test and video-head-impulse test in patients with definite Meniere's disease and compare them between symptomatic, asymptomatic ears and those of the control group.

Vestibular evoked myogenic potentials in the prognosis of sudden hearing loss ‒ a systematic review.

Introduction: Sudden hearing loss is an otorhinolaryngological emergency that often leads to severe damage to the auditory and vestibular function. The vestibular evoked myogenic potential is a test that allows a noninvasive evaluation of the otolithic system function and vestibulospinal and vestibulo-ocular pathways.

Objective: To evaluate the importance of vestibular evoked myogenic potential in determining the prognosis of patients with sudden hearing loss.

Cervical vestibular evoked myogenic potentials and video head impulse test in Ménière disease.

Introduction: Ménière's disease is among the most frequent causes of vestibular disorders. Although it is a clinical diagnosis, a better understanding of the pathophysiology and clinical course of the disease through tests would allow improvement in the prognosis and more effective treatments.

Objectives: To describe the results of the cervical vestibular evoked myogenic and video head impulse test in patients with a defined diagnosis of Ménière's disease and to correlate them with disease duration.

Ménière's Disease: Molecular Analysis of Aquaporins 2, 3 and Potassium Channel KCNE1 Genes in Brazilian Patients.

Objectives: Ménière's disease (MD) is a complex disease of unknown etiology characterized by a symptomatic tetrad of vertigo, hearing loss, tinnitus, and aural fullness. In addition to factors related to homeostasis of the inner ear, genetic factors have been implicated in its pathophysiology, including genes related to the transport of water and ionic composition maintenance of the endolymph, such as the aquaporin genes AQP2 and AQP3, and the potassium channel gene KCNE1. The aim of this study was to identify polymorphisms of these genes and determine their association with clinical characteristics of patients with MD.

Graphic angle measure as an electrocochleography evaluation parameter.

Unlabelled: To improve electrocochleography's diagnostic sensitivity in Meniére's disease - new assessment methods are being studied.

Aim: To determine whether or not graphic angle measurement is sensitive and specific to Menière's disease laboratorial diagnosis and if there is an increase in the electrocochleography's sensitivity and specificity when graphic angle measurements are associated with Summating Potential-Action Potential ratio (SP/AP ratio).

Methods: Electrocochleography's was used to analyze 71 ears from 55 subjects: 41 patients with clinical diagnosis of Menière's disease (MD group), and 14 healthy individuals as control (Group C).

Blood glucose and insulin levels in patients with peripheral vestibular disease.

Unlabelled: Metabolic disorders can cause dizziness.

Aim: to study the prevalence of glucose and glucose-insulin alterations in patients with peripheral vestibular disorders by studying the four-hour glucose-insulin curve; to check at what time there was the highest prevalence of altered cases and whether the glucose and insulin curves together are better than the isolate glucose curve and fasting glucose curve.

Materials And Methods: retrospective study, analyzing 81 four-hour glucose-insulin curves in patients with peripheral vestibular dizziness.

Evoked response audiometry according to gender and age: findings and usefulness.

Unlabelled: Auditory evoked brainstem responses (ABR) is a non-invasive electrical potential registration which evaluates the auditory tract from the middle ear to the auditory cortex in the first 12 milliseconds (ms). The ABR is an important otoneurological evaluation.

Aim: Confirm the test's usefulness, major incidence and topography according to are range gender considering the absolute latencies of the waves and interpeak intervals.

he relationship between spatial body positioning and environment comes from perfect corporal balance. The three most important systems responsible for this relationship are: the optic system (sight), the proprioceptive system, and the labyrinthine system. : retrospective clinical.

Comparison between radiological and nasopharyngolaryngoscopic assessment of adenoid tissue volume in mouth breathing children.

The pharyngeal tonsil (adenoid) constitutes the upper portion of the Waldeyer's ring and is located at the top of the nasopharynx, next to the auditory tube and choana. It plays an important role in recurrent otitis of the middle ear and many times its enlargement is responsible for upper airway obstruction. Tonsillectomy is often the treatment of choice for tonsillar diseases.
