Usher syndrome (USH) is an autosomal recessive disorder characterized by sensorineural hearing loss, progressive visual loss and night blindness due to retinitis pigmentosa (RP), with or without vestibular dysfunction. The purpose of this study was to detect the causative gene in a consanguineous Chinese family with USH. A c.3696_3706del (p.R1232Sfs*72) variant in the myosin VIIa gene (MYO7A) was identified in the homozygous state by exome sequencing. The co‑segregation of the MYO7A c.3696_3706del variant with the phenotype of deafness and progressive visual loss in the USH family was confirmed by Sanger sequencing...

Studies of multisensory integration by single neurons have traditionally emphasized empirical principles that describe nonlinear interactions between inputs from two sensory modalities. We previously proposed that many of these empirical principles could be explained by a divisive normalization mechanism operating in brain regions where multisensory integration occurs. This normalization model makes a critical diagnostic prediction: a non-preferred sensory input from one modality, which activates the neuron on its own, should suppress the response to a preferred input from another modality...

Hermissenda crassicornis is a model for studying the molecular and cellular basis for classical conditioning, based on its ability to associate light with vestibular stimulation. We used confocal microscopy to map histamine, FMRF-amide, and GABA immunoreactivity in the central nervous system (CNS), eyes, optic ganglia and statocysts of the nudibranchs. For histamine immunoreactivity, we documented both consistently and variably labelled CNS structures across individuals. We also noted minor differences in GABA immunoreactivity in the CNS compared to previous work on Hermissenda...

Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, accounting for 20% of all vertigo cases. Idiopathic BPPV is most common between the ages of 50 and 70, although the condition is found in all age groups. This study was conducted in our institute on 90 patients who presented to the outpatient department with history of vertigo and were diagnosed with BPPV via a positive Dix Hallpike test. Patients were randomnly placed in three groups of 30 each. Patients in Group A were treated with Epleys manoeuvre alone, in Group B were treated with Epleys Manouvre followed by oral Betahistine and patients in Group C were treated with Betahistine alone...

OBJECTIVES: With rising quality of speech perception in cochlear implant users, the indication widens. Nowadays, cochlear implantation is reasonable even in vestibular schwannoma patients. Speech perception with a cochlear implant is in these patients as promising as in patients with sensorineural hearing loss. However, the impact of cochlear implantation on vertigo and tinnitus after removal of vestibular schwannoma has not been investigated yet. METHODS: In a retrospective study, we analysed 12 patients treated with a cochlear implant after removal of vestibular schwannoma...

An elderly male patient diagnosed with a right-sided cystic vestibular schwannoma (CVS) at our center underwent a translabyrinthine approach with a subtotal excision to preserve the facial nerve (FN). The tumor grew slowly for the first 9 years but in the subsequent 2 years grew rapidly, with the patient developing a FN paralysis. Using the previous approach, a second surgery was done and the tumor was excised, leaving behind a sheath of tumor on the facial and lower cranial nerves. This case demonstrates that CVSs show unpredictable growth patterns and need to be followed up for a longer period of time...

Functional vertigo and dizziness (VD) symptoms are highly prevalent and usually accompanied by a strong impairment of quality in everyday and working life. The complaints are often associated with various psychiatric disorders, particularly phobic and other anxiety disorders, depressive or somatoform disorders. Despite this clinical relevance of VD symptoms, studies towards psychotherapeutic treatment options for patients with functional VD are still rare. Thus, the present study outlines a manual for outpatient group therapy for patients with functional VD symptoms...

Physical exercise has been shown to improve cognitive functions. However, it is still unknown which type of exercise affects cognition. In the present study, we tested the hypothesis that a demanding balance training program improves memory and spatial cognition. Forty healthy participants aged 19-65 years were randomly assigned to either a balance or relaxation training intervention. Each group exercised twice a week for a total of 12 weeks. Pre- and posttests assessed balance performance, cardiorespiratory fitness, memory, spatial cognition, and executive functions...
