33 patients (9 male and 24 female) aged 28-59 (average 43,2) with multiple sclerosis were tested on the base of electro/videonystagmography. The duration of the disease was from half a year to 26 years. The aim of this study was to estimate the frequency of the central and peripheral vestibular disturbances in multiple sclerosis due […]
Several prognostic indicators of favorable outcome in idiopathic sudden sensorineural hearing loss (ISSHL) have been proposed: an initial profound hearing loss, a down-sloping audiometric curve, advanced age, and the presence of vertigo. The latter has been disputed in the literature. The present study addressed the correlation between vertigo and outcome of ISSHL. Sixty-seven patients with […]
Transtympanic gentamicin administration has become a popular modality in the treatment of Ménière’s disease. This modality and other inner-ear medical therapy are gaining increased clinical and scientific attention.
The aim of this study was to highlight the clinical characteristics of tinnitus and to attempt a quantitative assessment in relation to any underlying etiologies. We undertook to study a population of 123 patients attending a tinnitus clinic between 1998 and 2000.
It is known that equilibrium disorders caused by involvement of brainstem-cerebellar structures are common in patients with Multiple Sclerosis (MS), but peripheral conditions such as Benign Paroxysmal Positional Vertigo (BPPV), can be sometimes confused with those of central origin. Therefore, an accurate otoneurologic investigation paying attention to differential diagnosis aspects should be performed in these […]
The variety of suggested treatments of nystagmus probably reflect its multiple pathogenetic mechanisms. Basic studies have shown that several neurotransmitters are involved in the ocular motor control, including gamma-aminobutyrric acid (GABA), acetylcholine and glycine. Recently, Stahl et al. (1995 ) investigated the effects of gabapentine on acquired pendular nystagmus in two patients with multiple sclerosis. […]
THE FUNCTION OF THE VESTIBULO-OCULAR REFLEX (VOR) IS TO STABILIZE VISUAL IMAGES ON THE RETINA DURING HEAD MOVEMENTS, THEREBY ENSURING MAXIMAL VISUAL ACUITY. IT IS POSSIBLE TO OBTAIN RELIABLE AND QUANTITATIVE INFORMATION ON VESTIBULAR FUNCTION USING A MOTORISED CHAIR, WITH THE SUBJECT’S HEAD AND BODY FIXED. SUCH TESTING OF THE VOR HAS ENTAILED LOW-FREQUENCY ROTATION […]
The vascular system and its influence under sympathetic and parasympathetic stimulations plays an essential role in neurophysiology of equilibrium.
The relationship between occlusion and equilibrium system must be interpreted as a base condition to program a rehabilitation, both in stomatognatic problems and in equilibrium problems. Use of stabylometric system, using references to vestibular, visual, somatosensorial systems, the stabylometric system allows to evaluate the interferences occurring during compensation within the single parts that made the […]
THE ROLE OF THE VESTIBULAR SYSTEM IS TO INTEGRATE POLISENSORIAL CUES AND PROVIDE A CONTINUOS AND PRECISE REPRESENTATION EITHER OF THE BODY SHAPE (SEGMENTAL BODY ORIENTATION, THAT TO SAY PERCEPTION OF THE RECIPROCAL POSITION OF BODY SEGMENTS ) OR THE ORIENTATION OF THE BODY INTO THE ENVIRONMENT (SPATIAL ORIENTATION). MELATONIN IS A NATURAL HORMONE SECRETED […]
