INTRODUCTION AND OBJECTIVES The caloric test is the gold standard for the loss of vestibular function diagnosis. The Video Head Impulse Test (vHIT) assesses the same reflex by using a video- assisted examination of the impulsive maneuver. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at...

INTRODUCTION The aim of the study was to compare air and water caloric stimulation of the vestibular organs using videonystagmography (VNG). MATERIAL AND METHODS The study covered 18 women aged 21-63 and 11 men aged 21-74 years hospitalized at the ENT, without complaints for vertigo and/or balance disorders. The alternate binaural bithermal caloric test with cool 30°C and warm 44°C air or wat...

BACKGROUND the use of monothermal caloric testing as a screening tool for vestibular asymmetry has been considered as an alternative to bithermal caloric testing. AIM to evaluate the effectiveness of monothermal stimulation when compared to bithermal stimulation in the diagnosis of labyrinth asymmetry. METHOD the results of 389 vectoelectronystagmography, performed between 1998 and 2007, we...

OBJECTIVE/HYPOTHESIS Although most studies have identified damage in the cochlea and semicircular canals as the primary sites of aminoglycoside toxicity, little attention has been devoted to the toxic effects on the otolithic organs. This study aimed to assess the toxic effect of gentamicin eardrops on the inner ear end organs via a novel inner ear monitoring system combined with morphological ...

In this issue, Silveira et al. report on analyses of three nationally representative studies of Brazilian children, conducted in 1989, 1996, and 2006/7. The analytic sample was restricted to ages 24 to 60 months. Silveira et al. find that the prevalence of overweight in this age group increased from 3.0% in 1989 to 7.8% in 2006/7, that most of the increase occurred between 1996 and 2006/7, and ...

Does it matter in what order the four irrigations are conducted in the caloric test? It has been suggested that warm water (44 degrees C) elicits stronger reactions than does cold water (30 degrees C), which might be explained simply by slight differences in water temperatures. However, if it can be shown that starting with cold water diminishes the difference between the warm and cold irrigati...

MATERIALS and METHODS: Forty patients with complaints of vertigo and dizziness volunteered to be included in the study. All patients who were included the study were treated at the other medical centers. The patients were divided into two Groups. Patients in the first Group were given betahistine 24 mg three times per day. During this treatment, caloric testing was performed, and the dose was i...

OBJECTIVE Bithermal caloric tests are among those most commonly used in vestibular function studies and require a properly systematized approach. Irrigation sequence varies between laboratories. Our objective is to study the effect of irrigation sequence on the percentage of vestibular paresis. MATERIAL AND METHOD We analysed 1214 records, 77.51% cold to hot sequences (C-H) and the rest hot t...

OBJECTIVE Cognitive factors and anticipation are known to influence food intake. The current study examined the effect of anticipation and actual consumption of food on hormone (ghrelin, cortisol, and insulin) and glucose levels, appetite and ad libitum intake, to assess whether changes in hormone levels might explain the predicted differences in subsequent food intake. DESIGN AND METHODS Dur...

This brief study investigates the extent and origin of the apparent dependency of air delivery speculum size on the effectiveness of air used as a stimulus in the bi-thermal caloric test, using water as a reference stimulus. Eleven normal volunteers served as subjects. Six caloric stimulus delivery conditions included air with two speculum sizes, speculum only and with a rubber tube extension, ...
