A short course of corticosteroids is among the management strategies considered by specialists for the treatment of vestibular neuritis (VN). We conducted an umbrella review (systematic review of systematic reviews) to summarize the evidence of corticosteroids use for the treatment of VN. ⋯ There is limited evidence to support the use of corticosteroids for the treatment of VN in the emergency department.

Multicenter Study
Effectiveness and reliability of the 4-step STANDING algorithm performed by emergency interns and seniors for predicting central causes of vertigo.
For emergency physicians (EPs), acute vertigo is a challenging complaint and learning a reliable clinical approach is needed. STANDING is a four-step bedside algorithm that requires (1) identifying spontaneous nystagmus with Frenzel glasses or, alternatively, a positional nystagmus; (2) characterizing the nystagmus direction; (3) assessing the vestibuloocular reflex (head impulse test); and (4) assessing the gait. The objective was to determine its accuracy for diagnosing central vertigo when using by naïve examiners as such as interns and its agreement with senior EPs. ⋯ With a single training session, the algorithm reached high accuracy and reliability for ruling out central causes of vertigo in the hands of both novices and experienced EPs. A future multicenter randomized controlled trial should further its impact on unnecessary neuroimaging use and patient's satisfaction.

Review Meta Analysis
Vestibular Suppressants for Benign Paroxysmal Positional Vertigo: A Systematic Review and Meta-analysis of Randomized Controlled Trials.
Benign paroxysmal positional vertigo (BPPV) is a common cause of acute dizziness. Medication use for its treatment remains common despite guideline recommendations against their use. ⋯ In patients with BPPV, vestibular suppressants may have no effect on symptom resolution at the point of longest follow-up; however, there is evidence toward the superiority of CRM over these medications. Vestibular suppressants have an uncertain effect on symptom resolution within 24 h, repeat ED/clinic visits, patient satisfaction, quality of life, and adverse events. These data suggest that a CRM, and not vestibular suppressants, should be the primary treatment for BPPV.

This third Guideline for Reasonable and Appropriate Care in the Emergency Department (GRACE-3) from the Society for Academic Emergency Medicine is on the topic adult patients with acute dizziness and vertigo in the emergency department (ED). A multidisciplinary guideline panel applied the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the certainty of evidence and strength of recommendations regarding five questions for adult ED patients with acute dizziness of less than 2 weeks' duration. The intended population is adults presenting to the ED with acute dizziness or vertigo. ⋯ It is clear that as of 2023, when applied in routine practice by emergency clinicians without special training, HINTS testing is inaccurate, partly due to use in the wrong patients and partly due to issues with its interpretation. Most emergency physicians have not received training in use of HINTS. As such, it is not standard of care, either in the legal sense of that term ("what the average physician would do in similar circumstances") or in the common parlance sense ("the standard action typically used by physicians in routine practice").
