Zuma Modified Maneuver as a Treatment to Geotropic Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo.

Int Arch Otorhinolaryngol 2021 Apr 23;25(2):e255-e257. Epub 2020 Jun 23.

Department of Otorhinolaryngology, Pontifícia Universidade Católica, INSCER, Rio Grande do Sul, Porto Alegre, RS, Brazil.

 Benign Paroxysmal Positional Vertigo (BPPV) is the most common vestibular disorder, resulting from detached otoliths that migrate to one of the semicircular canals - canalolithiasis - or one of the cupulas - cupulolithiasis. The present study is related to lateral canal BPPVs, which may be either geotropic or apogeotropic. The geotropic variant of lateral semicircular canal benign paroxysmal positional vertigo (LC-BPPV) is attributed to free floating particles in the posterior arm of the lateral semicircular canal.

Identification of a genetic variant underlying familial cases of recurrent benign paroxysmal positional vertigo.

PLoS One 2021 6;16(5):e0251386. Epub 2021 May 6.

Vestibular Genetics Laboratory, Boys Town National Research Hospital, Omaha, Nebraska, United States of America.

Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo in humans, yet the molecular etiology is currently unknown. Evidence suggests that genetic factors may play an important role in some cases of idiopathic BPPV, particularly in familial cases, but the responsible genetic variants have not been identified. In this study, we performed whole exome sequencing [including untranslated regions (UTRs)] of 12 families and Sanger sequencing of additional 30 families with recurrent BPPV in Caucasians from the United States (US) Midwest region, to identify the genetic variants responsible for heightened susceptibility to BPPV.

[Betahistine in vestibular disorders: current concepts and perspectives].

Vestn Otorinolaringol 2021 ;86(2):73-81

Federal Siberian Research Clinical Centre under the Federal Medical Biological Agency, Krasnoyarsk, Russia.

The goal of this paper is to review the pharmacological profile of betahistine and evidence for using it in the treatment of common vestibular disorders. Betahistine is a weak agonist for histamine H1 receptors and strong antagonist for histamine H3 receptors. It demonstrates the maximum benefit in different types of peripheral vertigo, especially in Meniere's disease. Read More

Department of Neurology, Lahey Hospital and Medical Center, 41 Mall Road, Burlington, MA 1805, USA; Tufts University School of Medicine, Burlington, MA, USA.

Vestibular symptoms, including dizziness, vertigo, and unsteadiness, are common presentations in the emergency department. Most cases have benign causes, such as vestibular apparatus dysfunction or orthostatic hypotension. However, dizziness can signal a more sinister condition, such as an acute cerebrovascular event or high-risk cardiac arrhythmia. Read More

[Update on diagnosis and therapy in frequent vestibular and balance disorders].

Fortschr Neurol Psychiatr 2021 Apr 19. Epub 2021 Apr 19.

LMU Klinikum, Neurologische Klinik und Deutsches Schwindel- und Gleichgewichtszentrum (DSGZ).

The 8 most frequent vestibular disorders account for more than 70% of all presentations of vertigo, dizziness, and imbalance. In acute (and mostly non-repetitive) vestibular disorders acute unilateral vestibulopathy and vestibular stroke are most important, in episodic vestibulopathies benign paroxysmal positional vertigo (BPPV), Menière's disease and vestibular migraine, and in chronic vestibular disorders bilateral vestibulopathy/presbyvestibulopathy, functional dizziness and cerebellar dizziness. In the last decade, internationally consented diagnostic criteria and nomenclature were established for the most frequent vestibular disorders, which can be easily applied in clinical practice.

Case Report: Could Hennebert's Sign Be Evoked Despite Global Vestibular Impairment on Video Head Impulse Test? Considerations Upon Pathomechanisms Underlying Pressure-Induced Nystagmus due to Labyrinthine Fistula.

Front Neurol 2021 29;12:634782. Epub 2021 Mar 29.

ENT Unit, Department of Surgery, Azienda USL-IRCCS di Reggio Emilia, Reggio Emilia, Italy.

We describe a case series of labyrinthine fistula, characterized by Hennebert's sign (HS) elicited by tragal compression despite global hypofunction of semicircular canals (SCs) on a video-head impulse test (vHIT), and review the relevant literature. All three patients presented with different amounts of cochleo-vestibular loss, consistent with labyrinthitis likely induced by labyrinthine fistula due to different temporal bone pathologies (squamous cell carcinoma involving the external auditory canal in one case and middle ear cholesteatoma in two cases). Despite global hypofunction on vHIT proving impaired function for each SC for high accelerations, all patients developed pressure-induced nystagmus, presumably through spared and/or recovered activity for low-velocity canal afferents.

Square wave manoeuvre for apogeotropic variant of horizontal canal benign paroxysmal positional vertigo in neck restricted patients.

J Otol 2021 Apr 5;16(2):65-70. Epub 2020 Nov 5.

Northwestern University, Chicago, IL, USA.

Objective: We aimed to describe the clinical features of the apogeotropic variant of horizontal canal benign paroxysmal positional vertigo (HC BPPV-AG) in a cluster of patients with restrictive neck movement disorders and a new therapeutic manoeuvre for its management.

Methods: In a retrospective review of cases from an ambulatory tertiary referral center, patients with HC BPPV-AG in combination with neck movement restriction that prevented any classical manual repositioning procedure or who were refractory to canalith repositioning manoeuvres, were treated with a new manoeuvre comprised of sequential square-wave pattern of head and body supine rotations while nystagmus was being monitored, until either an apogeotropic to geotropic conversion or resolution of the nystagmus was observed.

Results: Fifteen patients were studied. Read More
