Comparison Between the Video Head Impulse Test and Caloric Irrigation During Acute Vertigo
This study included 80 pa tients with acute onset vertigo who underwent caloric irrigation and vHIT. CI derived sum of slow phase velocities (SPVs) and unilateral weakness (UW) were compared with vHIT vestibulo-ocular reflex (VOR) gain and gain asymmetry (GA) using correlation analyses. Optimal cut offs for vHIT VOR gain and GA were calculated using Youden indexes. There was a strong positive correlation between the asymmetry measures UW and GA whereas the correlation between the sum of SPVs and VOR gain was weaker. The optimal cut offs to diagnose unilateral vestibular weakness were 0.80 for VOR gain and 28% for GA; w ith...

Video-Oculography to Guide Neuroimaging for Dizziness and Vertigo
Dizziness and vertigo are among the most common presenting symptoms in both the emergency department (ED) and ambulatory outpatient clinics, with recent estimates suggesting roughly 18 million visits per year in the US (nearly 5 million to EDs and>13 million to outpatient clinics). These symptoms are caused by a wide array of conditions, but the most common benign causes are otologic, and the most common dangerous cause is stroke. Stroke accounts for 3% to 5% of dizziness presentations in the ED, and some evidence suggests that it may account for a similar percentage of dizziness presentations in ambulatory care clinics...

Unclear origin vertigo protocol.
CONCLUSIONS: Our protocol has proven to be a useful tool to differentiate a possible acute vestibular syndrome of central origin from a peripheral one, avoiding unnecessary imaging tests. The most frequent cause of activation of the protocol was clinical-exploratory disagreement seen by the ENT doctor. PMID: 32862974 [PubMed - as supplied by publisher]

Risk Factors for the Recurrence of Benign Paroxysmal Positional Vertigo: A Systematic Review and Meta-Analysis.
CONCLUSION: These findings strengthen clinical awareness of early warning to identify patients with potential relapse risk of BPPV and clinicians should counsel patients regarding the importance of follow-up after diagnosis of BPPV. PMID: 32776833 [PubMed - as supplied by publisher]

Dizziness and vertigo in a  tertiary ENT emergency department.
CONCLUSION: BPPV is the most frequent diagnosis seen in the ED; however, physicians need to document nystagmus more precisely and perform diagnostic tests systematically, in order to make an accurate diagnosis. To avoid misdiagnoses, ED physicians and ENT specialists should be able to recognize central signs in patients with an acute vestibular syndrome. Every fourth patient does not receive a definitive diagnosis. Diagnostic ED workup for patients with dizziness needs further improvement. PMID: 32221628 [PubMed - as supplied by publisher]

An Educational Intervention for Acute Dizziness Care: A Randomized, Vignette-based Study
Importance: Benign paroxysmal positional vertigo (BPPV) is a common cause of acute dizziness. Strong evidence exists for diagnosing BPPV using the Dix-Hallpike Test (DHT) and treating it with the canalith repositioning maneuver (CRM). Despite this, both are infrequently used in the emergency department (ED). Objective: As an early method to evaluate a BPPV-focused educational intervention, we evaluated whether an educational intervention improved ED provider performance on hypothetical stroke and BPPV cases delivered by vignette. Design: A randomized, controlled, educational intervention study in ED physicians. The...

Acute vestibular asymmetry disorder: a new disease entity in acute vestibular syndrome?
CONCLUSIONS AND SIGNIFICANCE: Our study suggests that a normal HIT in AVS is not always a dangerous sign indicating an acute stroke. From our observations, we propose that AVAD would be a new disease entity within AVS. PMID: 31035836 [PubMed - as supplied by publisher]

Usage of the HINTS exam and neuroimaging in the assessment of peripheral vertigo in the emergency department
Dizziness is a common presenting symptom in the emergency department (ED). The HINTS exam, a battery of bedside clinical tests, has been shown to have greater sensitivity than neuroimaging in ruling out stroke...

Identification of dizzy patients who will develop an acute cerebrovascular syndrome: a descriptive study among emergency department patients
ConclusionEmergency department patients with symptoms of vertigo or dizziness had sevenfold higher risk of acute cerebrovascular syndromes than the general population. Atrial fibrillation and diabetes mellitus are risk factors associated with high risk of acute cerebrovascular syndromes in these patients.

Sleep apnea and risk of vertigo: A nationwide population ‐based cohort study
ConclusionThis is the first nationwide population‐based cohort study to investigate the association between sleep apnea and vertigo. The findings strongly support that sleep apnea is an independent risk factor for vertigo. Based on the study results, physicians should be aware of potential vertigo occurrence following sleep apnea. Level of Evidence4. Laryngoscope, 2017

Acute vestibular syndrome following cerebellar stroke : Case report and literature review. German version.
Authors: Volgger V, Gürkov R Abstract The current paper reports on a patient with recurrent rotational vertigo and persistent dizziness and imbalance lasting weeks, who underwent extensive neurootological and radiological examination. Pathological findings initially included right-sided benign paroxysmal positional vertigo (BPPV), persistent horizontal spontaneous nystagmus (SPN) to the left and a pathological bedside and video head impulse test (HIT) on the left. The pathological HIT on the left and SPN to the left indicated a central genesis. Therefore, cMRI was performed and revealed a left-sided cerebral i...
