Dizziness Evaluation and Characterisation of Patients with Posterior Circulation Stroke in the Emergency Department; a Case Series Study.

Introduction: Dizziness is a common scenario in the Emergency Departments (EDs). Among dizziness underlying causes, the posterior circulation stroke is especially relevant due to its mobimortality and concerning misdiagnosis rates. Therefore, we conducted this study to assess dizziness evaluation and baseline characteristics of patients with PS in the ED.

Is Skull Vibration-Induced Nystagmus Useful in Vestibular Neuritis Follow Up?

The aim of this study was to evaluate the vestibulo-ocular reflex (VOR) gain and the saccade regrouping pattern PR score of the Video Head Impulse Test (vHIT) and its relationship with the slow-phase velocity (SPV) of skull vibration-induced nystagmus (SVIN) in recovery after a unilateral vestibular loss (UVL). A total of 36 patients suffering from vestibular neuritis (VN) were recruited and followed up for twelve months. In every visit, horizontal vHIT and an SVIN were performed, as well as VOR gain; PR score and the SPV of SVIN were measured.

A Predictive Model of Bilateral Sensorineural Hearing Loss in Meniere Disease Using Clinical Data.

Objectives: Meniere disease (MD) is defined by a clinical syndrome of recurrent attacks of spontaneous vertigo associated with tinnitus, aural fullness, and sensorineural hearing loss (SNHL). Most patients have unilateral SNHL, but some of them will develop contralateral SNHL during the course of the disease. Several studies have reported a frequency of 2 to 73% SNHL in the second ear, according to the duration of disease and the period of follow-up.

The role of vertical semicircular canal function in the vertical component of skull vibration-induced nystagmus.

Generally, vertical component of the skull vibratory nystagmus (VCN) is ignored in the clinical practise. Thus, the relative contribution of the vestibular organs in the presence of VCN remains unknown. To determine the association between vertical semicircular canal (vSCC) function and the presence of VCN.

Can Benign Paroxysmal Positional Vertigo Be Treated in a One Session?

Objective: To determine the reliability and safety of posterior canal BPPV (pc-BPPV) treatment with subsequent assessment of the effectiveness of the maneuver in a single session, compared to the classic weekly procedure.

Method: A prospective study of two randomized groups of unilateral pc-BPPV was performed: a weekly management group (27 patients) and single-session treatment group (26 patients). The number of maneuvers required to clear pc-BPPV, incidence of side effects (re-entries and canal conversions), and recurrence rates were compared.

Valencia's Cathedral Church Bell Acoustics Impact on the Hearing Abilities of Bell Ringers.

Studies on the effect of occupational noise have been widely performed for occupations such as construction workers, workers of factories or even musicians and workers of nightclubs. However, studies on the acoustics of church bells are very scarce and usually reported in languages other than English. In Spain, although the tradition of bell ringers is progressively getting lost, some bell ringers that continue transmitting the tradition remain.

Parameters of skull vibration-induced nystagmus in normal subjects.

Hypothesis: The knowledge of vibration-induced nystagmus test (SVINT) values in the normal population is highly relevant to provide a rapid orientation on the diagnosis attitude in a patient with vertigo.

Background: Although mastoid bone vibration should only induce nystagmus in the presence of vestibular asymmetry, it has also been reported in normal individuals raising doubts as to how to interpret the SVINT. To date, no population studies involving the use of the SVINT and that establish normative values have been published.

Ipsilesional Nystagmus Induced by Vibration in Subjects With Ménière's Disease or Vestibular Schwannoma.

Objective: To analyze the frequency in which vibration-induced nystagmus (VIN) with ipsilesional direction appears in subjects with Ménière's disease (MD) or vestibular schwannoma (VS).

Study Design: Cross-sectional study.

Setting: Tertiary referral center.

Atypical periodic alternating nystagmus responding to high-dose intravenous immunoglobulins: a case report.

Background: Acquired periodic alternating nystagmus (PAN) is a rare but well-defined syndrome that consists of a horizontal nystagmus that cyclically reverses its direction. PAN can be caused by degenerative, neoplastic, or toxic diseases of the cerebellum and, in a few cases, by subacute cerebellar ataxia of immune origin.

Case Presentation: A 44-year-old man came to our attention because of rapidly progressive gait instability and blurred vision.

Clinical Subgroups in Bilateral Meniere Disease.

Meniere disease (MD) is a heterogeneous clinical condition characterized by sensorineural hearing loss, episodic vestibular symptoms, and tinnitus associated with several comorbidities, such as migraine or autoimmune disorders (AD). The frequency of bilateral involvement may range from 5 to 50%, and it depends on the duration of the disease. We have performed a two-step cluster analysis in 398 patients with bilateral MD (BMD) to identify the best predictors to define clinical subgroups with a potential different etiology to improve the phenotyping of BMD and to develop new treatments.

Response Over Time of Vertigo Spells to Intratympanic Dexamethasone Treatment in Meniere's Disease Patients.

Objective: To assess the effectiveness and response over time of intratympanic dexamethasone on the symptoms of Meniere's disease.

Materials And Methods: We performed a matched cohort study of 24 patients with Meniere's disease who were unresponsive to initial treatment and underwent 3 sessions of weekly intratympanic dexamethasone injections using a concentration of 16 mg/mL and 24 matched controls with the same characteristics with regard to vertigo spells.

Results: Compared with control subjects, intratympanic dexamethasone injections resulted in a decrease in the frequency of vertigo spells in the first 6-month period.
