Ketamine, or ketamine hydrochloride, is a non-barbiturate, rapid-acting disassociative anesthetic: the primary central nervous system action of ketamine appears to be a non-competitive block of NMDA (named after the selective agonist N-methyl-D-aspartate). In the current study, we examined the effect of ketamine on cortical and subcortical function by exploiting evoked eye movements: we analyzed the […]

Objectives: An isolated directional preponderance (PD) on bithermal caloric testing leaves many doubts to neurootology. It is considered by some to be as a transient, benign disorder (Halmagy, GM et al). We tried to elucidate if the PD can be considered important for the clinical diagnosis, without anamnesis. Methods: A retrospective study of 136 electronystagmographies, […]

In Hungarian expertise the patients with vertigo and sensorineural hearing loss and tinnitus are examined and treated in special outpatient departments of hospitals. Authors are analyzing the data of their patients, which were examined in the last two years in their otoneurological outpatient department. Most of the patients reach the outpatient department from general otolaryngological […]

Phlethysmogram monitoring degree of the vessel extension would show condition of the blood flow. Impaired blood flow in the peripheral and central vestibular system is one of the major causes of acute onset of vertigo. In younger patients, phlethysmogram sometimes showed unbalance of the blood flow in the right and left side. Surprisingly the side […]

The goal of this work is to study the vestibular system of whiplash people using a 3D dCCG system. A new experimental set-up, based on optoelettronic technique, was developed to evaluate the 3D pattern of movement of head and trunk in different experimental set-ups. The exam protocol is very close to the classical one with […]

It is known that the lower atmospheric pressure is highly related with orthopedic pain. It also seemed there was relationships between the pressure and onset of vertigo. Professor Wada in Japan reported the relationships at the congress as an invited speaker. Our question is what patients’ factors are responsible for the onset. Lower atmospheric pressure […]

Patients suffering from Ménière’s disease are particularly sensitive to negative pressure in the middle ear. E.g. attacks of vertigo can be triggered by a descent in an aircraft when ventilation of the middle ear can become critical. Positive pressure pulse treatment has shown to have a beneficial effect on the symptomatology, and is now a […]

Many authors had reported different useful studies in the evaluation of the vestibular function through vestibular, somatosensorial, viso-cortical systems in the Test of Balance.1,8 and to study the vestibular function through vestibuloespinal system in the Cranio-Corpo-Graphy (CCG) 2,3,4 Upon researching 100 patients suffering from vertigo we found that 36 % of them were male patients […]

Paroxysmal Positional Vertigo (PPV) is the most frequent kind of vertigo. It is a recognized as an inner ear problem caused by small calcium carbonate crystals that float through the inner ear fluid and strike against the cupula of semicircular canal. Authors have observed in a retrospective statistical analysis of 575 patients through 5 years […]

CranioCorpoGraphy (CCG) is one of the most common test to evaluate equilibrium and coordination, studying the pattern of movement of markers placed on the head and trunk. The aim of this work is the assess the coordination of healthy people in different experimental set-ups through a 3D dCCG system. So an optoelectronic system in a […]
