BACKGROUND To characterize the findings of brainstem auditory evoked potential in HIV-positive individuals exposed and not exposed to antiretroviral treatment. MATERIAL AND METHODS This research was a cross-sectional, observational, and descriptive study. Forty-five HIV-positive individuals (18 not exposed and 27 exposed to the antiretroviral treatment - research groups I and II, respectively...

Blink reflex, corneal reflex, jaw reflex, exteroceptive suppression in masseter muscles and brainstem auditory evoked potentials were measured in 20 patients with Huntington's chorea and 12 controls. A significantly increased latency of the second component of the homolateral and heterolateral blink reflex was found in the patient group as compared with the controls. The other investigations re...

Introduction Radiological assessment plays a vital role in identifying auditory neuropathy spectrum disorder (ANSD) children. Identifying the neonatal risk factors and their association with radiological findings might facilitate management of children ANSD. The goal current work was to investigate relationship between perinatal Material methods Altogether, 28 ANSD aged 1 6 were enrolled. Behav...

Bickerstaff's brainstem encephalitis is characterized by ophthalmoplegia, ataxia, and disturbance of consciousness. It is similar to Miller Fisher syndrome, a variant of Guillain-Barre syndrome, in that they share features such as ophthalmoplegia and ataxia. The difference is that patients with Bickerstaff's brainstem encephalitis have impaired consciousness, whereas patients with Miller Fisher...

background and aim: the sexual hormones alter during menstrual cycle and pregnancy. despite the physiological benefits of these changes, their adverse effects on hearing system such as hearing loss and vertigo have been reported. therefore, in this study, the auditory brainstem responses (abr) were investigated during physiological hormonal variations in the menstrual cycle as well as pregnancy...

acute necrotizing encephalopathy of childhood (anec) is a specific type of encephalopathy. after viral infection, it  can be diagnosed by bilateral symmetrical lesions that are predominantly observed in thalami & brainstem of infants & children. although, it is commonly occurred in japanese and taiwanese population. the goal of this article is to report a rare case of anec in  north part of ira...

OBJECTIVE To compare the outcomes (auditory threshold and open-set speech perception at 48-month follow-up) of a new near-field monitoring procedure, electrical compound action potential, on positioning the auditory brainstem implant electrode array on the surface of the cochlear nuclei versus the traditional far-field electrical auditory brainstem response. STUDY DESIGN Retrospective study. ...

iChirp-evoked auditory brainstem responses (ABRs) yield a larger wave V amplitude at low intensity levels than traditional broadband click stimuli, providing a reliable estimation of hearing sensitivity. However, advantages of iChirp stimulation at high intensity levels are unknown. We tested to see if high-intensity (i.e., 85 dBnHL) iChirp stimulation results in larger and more reliable ABR wa...
