BACKGROUND AND OBJECTIVES To investigate whether different vestibular function tests such as cervical vestibular evoked myogenic potential (cVEMP) and caloric test were correlated with severity, pattern and prognosis in idiopathic sudden sensorineural hearing loss (ISSNHL). SUBJECTS AND METHODS Ninety-two patients with unilateral ISSNHL were subjected to complete audiovestibular evaluation. c...

Introduction A patient who had no symptoms suggestive of bilateral loss of vestibular function presented no responses in rotational and caloric tests. Objectives To demonstrate the importance of the video head impulse test in neuro-otologic diagnosis. Resumed Report This patient had a neuro-otologic evaluation and presented no responses in torsion swing tests, caloric tests, and rotational test...

Background and Objectives:The caloric test is considered to be one of the most sensitive parameters in the diagnosis of peripheral vestibular disorders, although it can test only the function of the lateral semicircular canals. In this study, the authors measured the eye movements and visual suppression of caloric nystagmus in cats three dimensionally using a magnetic search coil system. Materi...

OBJECTIVES/HYPOTHESIS To identify the clinical and laboratory characteristics of bilateral vestibulopathy (BVP) on the video head impulse test (vHIT). STUDY DESIGN Retrospective chart analysis. METHODS During 23 months, 1,789 patients with dizziness underwent vHIT in our tertiary referral hospital. Of these patients, 65 (3.6%) patients had bilaterally positive catch-up saccades. Based on th...

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...

In 1906 Robert Barany published his original research on the caloric test and his convection theory to explain the direction of nystagmus. Subsequent publications by others suggested different explanations, including the effect of temperature on the vestibular nerves, pressure changes in the ampulla related to temperature expansion, but also the possibility of otolith modulation of the response...

calorie restriction through ingesting no or minimal amounts of food and caloric beverages for periods of time is called fasting. fasting can affect body through changing in physical and metabolic adaptations, as well as mineral and hormonal status. however, psychological effects and sometimes medical complications are likely in case of inappropriate fasting. fasting is associated with changes i...

Background Caloric restriction induces mitochondrial biogenesis and improves physical fitness in rodents. We aimed to provide evidence of how caloric restriction affects the body composition and physical performance of trained athletes and to evaluate the possible impact of an every-other-day feeding diet on nutritional deficiencies of micronutrients and essential fatty acids. Methods The stu...
