Vertigo and other neurootological signs in cases after apoplexia
An apoplectic stroke means sudden neurologic impairment due to a cerebrovascular disorder, limited by some to intracranial hemorrhage, extended by others to include occlusive cerebrovascular lesions. Cerebrovascular accidents may occur at any age, but intracerebral hemorrhage and thrombosis are rare before age 40 years. Peak incidence for cerebral thrombosis is at age 50 – 70 […]
The influence of cerebellar lesions on the otolith postural reflexes-experimental study
Between main postural reflexes, there are tonic labyrinth reflexes generated in otolith system as a results of earth gravity. The neck extensors action is a result of these reflexes and the medullar structures are their centers. It is known that the rigidity of decerebrated animals is caused by the fastigial nucleus damage and that this […]
Vertigem , fobia e pânico
Objetivo – entender a associação entre vertigem, fobia e pânico Método – 30 pacientes vertiginosos foram analisados por meio de entrevista livres e semidirigida de base psicanalítica como procedimentos de investigação deste trabalho, devido a riqueza dos mecanismos mentais inconscientes. Resultados – O afeto desencadeante e predominante nas fobias é a ansiedade, que designa a […]
The early kinetics of gentamicin uptake into the inner ear
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.
Electro-otolithography: new insight into benign paroxysmal positioning vertigo
Early vestibular evoked potentials were recorded with an extratympanic electrode. The recording principle was adding responses phase locked to a recording frequency. The recording frequency was empirically determined to match harmonically an individual response frequency and thus allowing averaging. This new technique was evaluated in benign paroxysmal positioning vertigo. Normal data were obtained from 12 […]
Characteristics of tinnitus and etiology of associated hearing loss: a study of 123 patients
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.
Vestibular findings in degenerative cns lesions
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 […]
Contribution of neuro-otology to differential diagnosis of vertigo in multiple sclerosis
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 […]
Clonazepam in the pharmacological treatment of vertigo and tinnitus
We carried out a retrospective survey of 25 years of clinical experience with the use of clonazepam as a vestibular and tinnitus suppressant in the pharmacological treatment of vestibular or cochleovestibular disorders due to different causes.
