The head impulse, nystagmus type, test of skew (HINTS) protocol set a new paradigm to differentiate peripheral vestibular disease from stroke in patients with acute syndrome (AVS). relationship between degree truncal ataxia and has not been systematically studied AVS. We group 114 who were admitted General Hospital due AVS, 72 them neuritis (based on positive abnormal caloric tests negative MRI), the rest Stroke: 32 PICA territory (positive HINTS findings, MRI) 10 AICA (variable findings...
Although head trauma is considered a common cause of benign paroxysmal positional vertigo (BPPV), clinical presentation and outcome traumatic BPPV (t-BPPV) have not been systematically evaluated.To compare the presentation, patient's response to physical treatment, patients with t-BPPV those idiopathic form (i-BBPV).Tertiary referral neuro-otology outpatient clinic.We reviewed records 247 consecutive posterior canal during years 1997 2000. All were diagnosed using Dix-Hallpike test treated...
Ten patients with relapsing-remitting multiple sclerosis were treated intravenous immune globulin, 0.4 g/kg per day for 5 consecutive days, and then additional booster doses of globulin g/kg, once every 2 months, the next 12 months. untreated who matched study age, disease duration, number attacks year served as controls. Immune treatment was well tolerated, no side effects. The exacerbation rate decreased from 3.7 +/- 1.2 exacerbations before to 1.0 0.7 during in globulin-treated patients,...
• Fourteen children with adenoid and tonsillar hyperplasia were studied for one night in the sleep laboratory. Six of had at least 40 apneic episodes per night, mostly central or obstructive. The largest number was found rapid eye movement sleep. Mixed longest shortest. Adenotonsillectomy performed on predominantly obstructive episodes. In two these children, preoperative postoperative recordings taken, revealing a reduction total complete disappearance These results suggest that...
The neural mismatch theory assumes that the intersensory conflicts leading to motion sickness are resolved by changes in relative weighting of various senses contribute orientation. If this sensory rearrangement persists after disembarkment, it might result mal de debarquement (MD): ataxia and a rocking sensation sometimes felt landing. objective present study was examine possible organization naval crew members with differing susceptibility MD computerized dynamic posturography...
To identify patients with benign paroxysmal positional vertigo (BPPV) among severe traumatic brain injury (TBI) and to evaluate the effectiveness of Particle Repositioning Maneouvre (PRM).Eighteen months prospective study 150 consecutive TBI referred an in-patients rehabilitation department.A structured interview emphasizing possible presence followed by a detailed neuro-otological examination. Patients diagnosed BPPV were immediately treated PRM.BPPV diagnosis was based on positive...
Although the diagnosis of inherited ataxias is ultimately genetic, this usually means an extensive and expensive process. This justifies search for distinct clinical signs that may potentially help orient molecular diagnosis.We explored vestibulo-ocular reflex (VOR) with video Head Impulse Test in patients diagnosed spinocerebellar ataxia (SCA) type 3 (n = 15), 1 4) 2 4), Friedreich's (FA) 9) healthy controls 40). We estimated latency, regression (VORr) instantaneous VOR gain at 40, 60 80 ms...
We assessed the influence of dimenhydrinate, cinnarizine and transdermal scopolamine on ability to perform simulated naval crew tasks. The effect single doses 100 mg, cinnarizine, 50 one patch psychomotor performance was evaluated using a double-blind, placebo-controlled, randomized, crossover design in three separate studies. A total 60 young (20 for 15 25 scopolamine) underwent battery computerized paper pencil tests, filled out questionnaire side-effects well-being self-assessment....
Diving-related inner ear barotrauma (IEB) and decompression sickness (IEDS) most often result in permanent severe cochleovestibular deficits, unless immediate diagnosis is reached the correct treatment commenced early. Nine cases of sport-diving-induced injuries that were referred to Israeli Naval Hyperbaric Institute between October 1987 September 1989 are presented with regard evaluation, treatment, follow-up. The was IEB five divers IEDS four. Explorative tympanotomy carried out...
To evaluate the effectiveness and possible side effects of a single session repeated particle repositioning maneuver (PRM) to treat posterior canal benign paroxysmal positional vertigo (BPPV) usefulness post-treatment restrictions.A total 125 consecutive patients with idiopathic BPPV participated in study. Fifty received PRM only (group I). Results were compared those 50 who IIb), 25 followed by use neck collar keeping head upright for 48 h IIa).Forty-six (92%) group I, 40 (80%) IIb, 21...
• Two patients with extensive necrotizing otitis externa have been treated by hyperbaric oxygenation. One patient had facial nerve palsy and the other suffered from skull base involvement. Due to severe side effects, preferred combined intravenous antibiotic therapy was changed monotherapy in one case completely withdrawn second. This done before commencement of oxygenation, while infection still active. Hyperbaric oxygenation followed complete resolution externa, which did not recur. The...
To identify the presence of vestibulo-ocular arreflexia in patients with Machado-Joseph disease (MJD), which can easily be diagnosed at bedside.Seven MJD from five unrelated families and 11 sporadic or hereditary cerebellar ataxia other than underwent a detailed neuro-otological oculomotor examination. Six non-MJD also electro-oculographic recordings caloric tests.Gaze evoked nystagmus, smooth pursuit, saccade abnormalities were found both patients. However, all seven but none patients,...
Histological and functional derangements of the vestibular system have been reported in laboratory animals exposed to high levels noise. However, clinical series describe contradictory results with regard disturbances industrial workers military personnel suffering from noise induced hearing loss (NIHL). The purpose present study was evaluate function a group subjects documented NIHL, employing electronystagmography (ENG) smooth harmonic acceleration (SHA) test. Subjects were 22 men NIHL 21...
Vestibulo-Ocular Reflex (VOR) abnormalities in cerebellar ataxias are a matter of renewed interest. We have previously reported vestibular areflexia group Yemenite-Jews with Spinocerebellar Ataxia Type 3 (SCA3) who had clear bilateral pathological horizontal Head Impulse Test (HIT). The objective this study was to evaluate the VOR ten SCA3 patients variable bedside HIT responses by recording their eye movements using magnetic search coils and correlate these results clinical genetic data....
