Our study presents two cases of neurofibromatosis 2 (NF2) that have been diagnosed at the Ear, Nose, and Throat Department of Hradec Králové (Czech Republic). The first case involved a young man with a history of sudden hearing loss accompanied by tinnitus on the left side. The diagnosis of NF2 was made, and an operation for left acoustic neuroma was performed. Looking toward the future, the ac...

Oxidative stress is believed to play a key role in tumor formation. Although this mechanism could be especially pertinent for brain tumors given the high oxygen consumption of the brain, very little has been published regarding brain tumor risk with respect to genes mediating oxidative stress. Using data from non-Hispanic whites in a hospital-based case-control study conducted by the National C...

BACKGROUND As a parameter for the evaluation of the vestibular evoked myogenic potential (VEMP), amplitude has been used clinically. However, the significance of latency has not been considered. OBJECTIVE To clarify the diagnostic value of latencies of the VEMP. DESIGN We reviewed records of the VEMP of patients with various diseases and compared them with records of healthy volunteers. S...

The medium and long-term effects of electrophysiologic monitoring on the facial nerve function in minimally invasive surgery treating acoustic neuroma were studied. Sixty-two patients with acoustic neuroma taking minimally invasive surgeries in Dezhou Hospital from August 2014 to September 2015 were selected and randomly divided into 29 cases of the control group and 33 cases of the observation...

Although the etiology of primary brain tumors is largely unknown, prior studies suggest that DNA repair polymorphisms may influence risk of glioma. Altered DNA repair is also likely to affect the risk of meningioma and acoustic neuroma, but these tumors have not been well studied. We estimated the risk of glioma (n = 362), meningioma (n = 134), and acoustic neuroma (n = 69) in non-Hispanic whit...

A 48-year-old Chinese woman presented with progressive right-sided sensorineural hearing loss. Computerised tomography showed asymmetrical widening of the right internal acoustic canal. Post-gadolinium magnetic resonance images demonstrated marked enhancement of an intracanalicular tumour. The diagnosis of acoustic neuroma was confirmed surgically. The approach to imaging of deafness, particula...

We use the radial baryon acoustic oscillation (BAO) measurements of Gaztañaga et al. (2008a) to constrain parameters of dark energy models. These constraints are comparable with constraints from other “non-radial” BAO data. The radial BAO data are consistent with the time-independent cosmological constant model but do not rule out time-varying dark energy. Subject headings: cosmological paramet...

We performed a retrospective study of 131 patients who underwent microsurgical removal of statoacoustic neuroma at the University of Wuerzburg. Our goal was to evaluate objective audiovestibular findings prior to and after surgery. Our analysis focused on the evaluation of quantitative parameters in speech and pure-tone audiometry and on the reactivity of the vestibular system.
