UNLABELLED The real participation of the vestibular folds during phonation mechanism is unknown. How vestibular folds change their configuration during phonation is still unclear. Learning about these changes in the functional mechanism of vestibular fold would be helpful for the evaluation of pathological conditions. AIM The objective of the present study was to analyze the configuration of ...

The ultimate purpose of eye movement is to maintain clear vision by ensuring that images observed objects are focused on the fovea in retina. Accurate evaluation ocular movements, including nystagmus and saccadic intrusions, provides very useful information for determining overall function abnormality complex oculomotor system, from peripheral vestibular system cerebrum. Eye tests therefore ess...

BACKGROUND Falls are the major cause of hip fractures in elderly patients. The aim of this prospective study was to investigate the underlying causes of fall-induced hip fractures in the elderly. METHODS The study included 32 patients (18 males, 14 females; mean age 78 years; range 57 to 95 years) who had proximal femoral fractures following an unexpected and sudden fall from about a meter he...

Vestibular neuritis is the most common cause of acute spontaneous vertigo. Vestibular neuritis is ascribed to acute unilateral loss of vestibular function, probably due to reactivation of herpes simplex virus in the vestibular ganglia. The diagnostic hallmarks of vestibular neuritis are spontaneous horizontal-torsional nystagmus beating away from the lesion side, abnormal head impulse test for ...

Since changes in vestibular function may be one cause of disequilibrium, major advances in measuring postural control and sensory integration in vestibular impairments have been achieved by using posturography. However, in order to overcome problems related to this type of technology, body-worn accelerometers (ACC) have been proposed as a portable, low-cost alternative to posturography for meas...

OBJECTIVE The value of vestibular rehabilitation in patients with bilateral vestibular dysfunction was investigated. MATERIALS AND METHODS This study assessed 17 patients (9 males, 8 females) with bilateral vestibular dysfunction. Vestibular rehabilitation continued for 1.5 months. Videonystagmography tests (including oculomotor testing, positional testing, and caloric tests), vestibular evok...

OBJECTIVE Galvanic vestibular stimulation (GVS) activates the vestibular afferents, and these changes in vestibular input exert a strong influence on the subject's posture or standing balance. In patients with Parkinson's disease (PD), vestibular dysfunction might contribute to postural instability and gait disorders. METHODS Current intensity was increased to 0.7 mA, and the current was appl...

Vertigo is uncommon in childhood. Its etiology is different from that of adults. Both central and peripheral disorders may give rise to vertigo symptoms in pediatric patients. The evaluation of vertigo in children requires a detailed history taking, clinical examination, audiometric assessment, and vestibular function tests. We present three pediatric patients with vertigo symptoms, together wi...

The diagnosis of Meniere's disease (MD) and vestibular migraine (VM) is primarily based on clinical criteria and their differentiation is often difficult. Currently, there are no known definitive diagnostic tests that can reliably distinguish the two conditions. Patients with MD and patients with VM are treated differently, therefore improving the diagnosis of these two pathologies should avoid...

OBJECTIVES/HYPOTHESIS Saposins are small proteins derived from a precursor protein, prosaposin. Each of the four saposins (A-D) is necessary for the activity of lysosomal glycosphingolipid hydrolases. Individual saposin mutations lead to lysosomal storage diseases, some of which are associated with hearing loss. Here we evaluate the effects of the loss of saposins C and D on auditory and vestib...
