INTRODUCTION  Sudden hearing loss (SHL) is an ENT emergency defined as sensorineural hearing loss (SNHL) ≥ 30 dB HL affecting at least 3 consecutive tonal frequencies, showing a sudden onset, and occurring within 3 days. In cases of SHL, a detailed investigation should be performed in order to determine the etiology and provide the best treatment. Otoacoustic emission (OAE) analysis, electronys...

Malus baccata (L.) Borkh. is one of the most widely used rootstocks in apple-producing region Northern China. However, early growing season, apple roots are often subjected to suboptimal low root-zone temperatures. The regulatory effects exogenous γ-aminobutyric acid (GABA) on both shunt (GABA shunt) and respiratory activity under temperatures remain unknown. To explore physiological basis for ...

Sound activates not only the cochlea but also the vestibular end organs. Research on this phenomenon led to the discovery of the sound-evoked vestibular myogenic potentials recorded from the sternocleidomastoid muscles (cervical VEMP, or cVEMP). Since the cVEMP offers simplicity and the ability to stimulate each labyrinth separately, its values as a test of human vestibular function are widely ...

OBJECTIVE The aim of the present study was to use constant and customized pressure levels to improve the feedback method of the blood pressure cuff technique in order to decrease intra-subject and inter-subject variability. MATERIALS AND METHODS The study was conducted in two stages. In the first stage, the relationship between the pressure level generated in the blood pressure cuff and elect...

BACKGROUND Cervical and ocular vestibular evoked myogenic potentials (c/oVEMPs) reflect otolith function. Up-to-date, there are no published reports on the systemic evaluation of otolith function in Ménière's Disease (MD) nor are there any reports on the differences in VEMPs between patients with early and late stage MD. The aim of this study was to evaluate the difference in c/oVEMPs between p...

Objective: The aim of this study was to evaluate audiovestibulopathy in patients with celiac disease using vestibular evoked myogenic potentials (VEMP), video head impulse test (vHIT), and audiometric examinations. Material Methods: Thirty-one from the gastroenterology department Cerrahpasa Medical School, 30 healthy controls were included between 2013 2015. Pure tone audiometry, tympanometry, ...
