[THE VIDEO HEAD IMPULSE TEST (VHIT)].

The video head impulse test (vHIT) is a new tool in the vestibular tests' arsenal. It is based on the clinical Head Impulse Test, where the integrity of the vestibulo-ocular reflex is tested by high frequency excitation of the semi-circular canals. The vHIT system is composed of an accelerometer measuring the head movements, and a high frequency infra-red camera for eye tracking mounted on a light-weighted goggles.

[THE VIDEO HEAD IMPULSE TEST (VHIT): CAN WE RELY ON THE GAIN PARAMETER ALONE?].

Introduction: While the bedside head impulse test evaluates the presence of refixation saccades (RS) as a measure of failing vestibulo-ocular reflex (VOR) the VOR gain calculated by the video head-impulse test (vHIT) is considered the primary measure for semicircular canal function while the role RS is still under evaluation.

Aims: To evaluate the benefit of various RS characteristics towards the diagnosis of the left horizontal semicircular function by vHIT.

Methods: The vHIT recordings of 40 patients with left sided horizontal VOR gains <0.

Refining the Video Head Impulse Test Diagnostic Accuracy: A Case-Control Study.

Introduction: Current clinical practice considers the vestibulo-ocular reflex (VOR) gain as registered by the video head impulse test (vHIT) as the primary measure for semicircular canal function, while the role of the re-fixation saccades (RSs) is still under evaluation. The goal of the study was to appraise the added benefit of RS towards the improvement of vHIT diagnostic accuracy in cases of suspected left horizontal semicircular canal dysfunction.

Methods: The vHIT recordings of 40 patients with left-sided horizontal VOR gains <0.

Bone Mineral Density in Patients Suffering from Ménière's Disease.

Introduction: Previous studies have reported an association between reduced bone mineral density and the occurrence of benign paroxysmal positional vertigo, balance impairment, and saccular dysfunction. Furthermore, the results of recent animal studies have raised the possibility that vestibular dysfunction could affect bone remodeling and bone mass. The goal of the study was to compare bone mineral density of patients suffering from definite Ménière's disease to that of a matched control group.

Case Report: Histoplasmosis: First Autochthonous Case from Israel.

We present an autochthonous infection in Israel. The patient presented with hoarseness and weight loss. Pathology findings and molecular tests confirmed the diagnosis, and the patient responded to antifungal therapy.

Hearing and Otoacoustic Emissions Outcome of Stapedotomy: Does the Prosthesis Diameter Matter?

Objective: To compare the hearing and otoacoustic emissions (OAE) outcome of stapedotomy employing 0.4 and 0.6 mm diameter prostheses.

Suppression of neuroinflammation and immunomodulation by the acetylcholinesterase inhibitor rivastigmine.

In this study we determined the influence of cholinergic up-regulation by rivastigmine, an acetylcholinesterase inhibitor, on central nervous system inflammation. Neuroinflammation was induced in experimental autoimmune encephalomyelitis (EAE). Rivastigmine markedly ameliorated clinical symptoms of EAE and the spatial memory deficits induced by EAE.
