Objectives: Direction-changing positional nystagmus (PN) was considered to indicate the presence of benign paroxysmal positional vertigo involving lateral semicircular canal in most cases. We investigated the incidence of PN on the supine head-roll test and compared the characteristics of nystagmus in patients with vestibular neuritis (VN) and Meniere disease (MD). Methods: A retrospective review of patients, who were diagnosed with unilateral VN or unilateral definite MD between September 2005 and November 2011, was conducted...

Vertigo is defined as an abnormal sensation of body motion or of its surrounding objects. It is a common chief complaint in emergency departments comprising 2 to 3% of these consultations worldwide. Vertigo is classified as peripheral or central, according to its origin, and can also be occasionally mixed, the most common cause of peripheral involvement being benign paroxysmal positional vertigo. The initial findings on clinical evaluation of patients are the clues for making a correct diagnosis. The differentiation between central and peripheral vertigo can be optimized by analysing nystagmus, by using the skew test and the head impulse test (HINTS), as also by performing the appropriate tests to evaluate the integrity of the vestibular-cerebellar pathway...

The assessment and treatment of sport-related concussion (SRC) often requires a multifaceted approach. Vestibular dysfunction represents an important profile of symptoms and pathology following SRC, with high prevalence and association with prolonged recovery. Signs and symptoms of vestibular dysfunction may include dizziness, vertigo, disequilibrium, nausea, and visual impairment. Identifying the central and peripheral vestibular mechanisms responsible for pathology can aid in management of SRC. The most common vestibular disturbances after SRC include benign paroxysmal positional vertigo, vestibulo-ocular reflex impairment, visual motion sensitivity, and balance impairment...

Acute vestibular disorder is a frequent cause of urgent hospitalization in elderly patients. A CNS vascular disorder is often thought to be a cause of vertigo and a patient is diagnosed with stroke or transitory ischemic attack (TIA) or vertebral-basilar insufficiency. Despite the higher risk of cerebrovascular disease in the elderly, stroke and TIA are not the only cause of acute vestibular disorder. Hyperdiagnosis of cerebrovascular diseases in patients with acute vertigo often leads to underdiagnosis of peripheral vestibular disorders that could be successfully treated if timely diagnosed...

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most frequent peripheral vestibular disorder and is particularly seen among older patients suffering from vertigo. The brief vertigo attacks in and imbalance symptoms of BPPV are caused by freely floating otoconia within the semicircular canals. The aim of this prospective study was to evaluate the role of oxidative stress, using native thiol/disulfide (SH/SS) homeostasis as a novel indicator, in the etiology of BPPV. MATERIALS AND METHODS: The 62 participants in the study included 31 patients with BPPV and, as the control group, 31 healthy individuals without any cochleovestibular disorders...

PURPOSE: The uses of nimodipine for otolaryngic indications are reviewed, and recommendations for its use in clinical practice are provided. SUMMARY: Nimodipine is currently indicated for the improvement of neurologic outcomes in adult patients with aneurysmal subarachnoid hemorrhage (aSAH). However, other oral and i.v. calcium channel blockers have not exhibited the same beneficial effects in patients with aSAH, leading clinicians to believe that nimodipine possesses unique neuroprotective effects in addition to its calcium channel-blocking and vasodilatory properties...

Vertigo and dizziness are frequent chief complaints in clinical practice. Symptoms may originate from otological, neurological, medical and psychiatric etiologies, which poses an interdisciplinary challenge. Systematic analysis of case history and clinical examination generally allow classification into peripheral-, central- or non-vestibular disorders. The most important criteria for differentiation are the timeline, quality of symptoms, modulating factors and accompanying symptoms. As concerns the clinical examination, the following tests are relevant: head impulse test, test for spontaneous nystagmus, positional nystagmus, central ocular motor signs and the Romberg test...

Dizziness is one of the most common causes of medical visits. Management of the dizzy patient may be challenging both for the general practitioner, in emergency departments, and special clinics, as behind a seemingly homogeneous clinical presentation several very different etiologies may occur. Research of the last two century enriched our knowledge about physiology and pathophysiology of the vestibular system. Much knowledge is now available about the labyrinth being able to sense head motions and gravity, processing of afferent vestibular stimuli, reflectory oculomotor and postural control, or recovery of the vestibular system...

BACKGROUND: Fabry Disease (FD) is an X-linked hereditary lysosomal storage disorder which leads to a multisystemic intralysosomal accumulation of globotriaosylceramid (Gb3). Besides prominent renal and cardiac organ involvement, patients commonly complain about vestibulocochlear symptoms like high-frequency hearing loss, tinnitus and vertigo. However, comprehensive data especially on vertigo remain scarce. The aim of this study was to examine the prevalence and characteristics of vertigo and hearing loss in patients with FD, depending on renal and cardiac parameters and get hints about the site and the pattern of the lesions...
