UNLABELLED The caloric test is an important tool for the assessment of labyrinthine function. OBJECTIVE To compare the nystagmus response in the caloric tests with air at 50ºC and 24ºC and with water at 44ºC and 30ºC. STUDY DESIGN Randomized crossover clinical trial. MATERIALS AND METHODS 40 healthy individuals were submitted to a neurotological evaluation, including caloric tests with ai...

Objective There is a lack of consensus regarding the indications for vestibular testing in the evaluation of dizziness and balance disorders. Geographic variation in health services utilization is associated with lack of consensus. To understand the variation in current practice, we investigated the patterns of use of vestibular testing and diagnosis codes for dizziness and balance disorders am...

Recent studies suggest that because of their energy value, sugars are more rewarding than non-caloric sweeteners. However, intragastric infusion data indicate that sugars differ in their postoral appetite-stimulating effects. We therefore compared the preference for isocaloric 8% sucrose, glucose, and fructose solutions with that of a non-caloric sweetener solution (0.8% sucralose) in C57BL/6J ...

BACKGROUND AND PURPOSE We report a novel finding of caloric conversion from normal responses into unilateral paresis during the acute phase of vestibular neuritis (VN). METHODS We recruited 893 patients with a diagnosis of VN at Dizziness Clinic of Seoul National University Bundang Hospital from 2003 to 2014 after excluding 28 patients with isolated inferior divisional VN (n=14) and those wit...

OBJECTIVE To clarify the extent of the vestibular lesions in idiopathic sudden hearing loss with vertigo using vestibular evoked myogenic potentials (VEMPs) in response to click (click-VEMP) and galvanic (galvanic-VEMP) stimulation, as well as caloric tests. DESIGN Retrospective study. SETTING University hospital. PATIENTS We enrolled 22 patients with idiopathic sudden hearing loss with v...

Audiovestibular symptoms are the first and often the only clinical signs of vertebrobasilar insufficiency. The aim of our investigation was to analyze the results of caloric and electronystagmographic investigation of vascular-vestibular disorders among patients with vertebrobasilar insufficiency. We examined a total of 55 men (mean age, 51.8 +/- 8.2 years)--a primary group of 35 men with prove...

To control and observe first feeding experiences, pups were reared without access to food. At weaning age, individual pups received simultaneous access to a palatable, noncaloric diet and a similar diet containing starch. Each diet contained a flavor cue. Within 20 min of sampling both diets pups preferentially ingested the caloric alternative. Further tests indicated that pups learned a prefer...

OBJECTIVE: 1) To correlate caloric results with sinusoidal and step-velocity rotary chair gain, phase, asymmetry and time constant values in all patients; 2) To evaluate sensitivity, specificity, positive predictive value and negative predictive value of both tests in patients with vestibular dizziness. STUDY DESIGN: Retrospective case review. SETTING: Academic tertiary care vestibular function...
