Effectiveness of vestibular rehabilitation therapy in patients with idiopathic Cerebellar Ataxia with Bilateral Vestibulopathy (iCABV).

Objective: To evaluate the benefit of vestibular rehabilitation therapy (VRT) in the management of patients with idiopathic cerebellar ataxia with bilateral vestibulopathy (iCABV).

Background: iCABV is a hindbrain degenerative disorder with impairment of both central and peripheral vestibular pathways. There is combined failure of four compensatory eye movement systems including the vestibulo-ocular reflex (VOR), optokinetic reflex, smooth pursuit and the visually enhanced vestibulo-ocular reflex (VVOR).

Post headshake nystagmus: further correlation with other vestibular test results.

Background: It is generally accepted that headshake nystagmus (HSN) is generated from an asymmetrical peripheral vestibular input and a correlation exists between HSN and canal paresis. There have been limited reports, however, how HSN correlates with the more recently introduced tests of vestibular function.

Aims/objectives: To evaluate the correlation between HSN and unilateral weakness on caloric testing, high-frequency vestibulo-ocular reflex (VOR) function on video head impulse testing (VHIT) and otolith function determined by vestibular evoked myogenic potentials (VEMPs).

Receiving Long-Term Disability or Pursuing a Legal Claim May Prevent Recovery From Chronic Dizziness.

Objectives/hypothesis: Chronic dizziness (CD) and imbalance have multiple etiologies. CD is strongly linked with psychiatric and psychological comorbidities, thus an interdisciplinary approach, including psychopharmacological interventions, is recommended. Despite the use of this comprehensive treatment approach, the recovery of individuals with CD that pursue long-term disability (LTD) insurance or legal claims (LC) appears hampered.

Contralesional High-Acceleration Vestibulo-Ocular Reflex Function in Vestibular Schwannoma.

Unlabelled: Impairment of ipsilesional vestibulo-ocular reflex (VOR) function is well described in vestibular schwannoma (VS) and a correlation between gain of the VOR and tumor size has been suggested. Bilateral VOR impairment may also occur in VS patients, but its mechanisms are poorly understood. We sought to explore the effect of unilateral VS on ipsilesional and contralesional high-acceleration VOR function using video head impulse testing, and evaluate potential factors responsible for contralesional VOR impairment.

The Relationship Between Disorders of Bone Metabolism and Benign Paroxysmal Positional Vertigo: A Systematic Review.

Objectives: Several studies have reported an association between benign paroxysmal positional vertigo (BPPV) and bone mineral density or serum vitamin D levels. The aim of this review is to provide further clarification regarding the relationship between BPPV and calcium metabolism.

Design: PubMed and MEDLINE databases were systematically reviewed to identify all English language papers regarding the relationship between BPPV and the following terms: osteoporosis, osteopenia, bone mineral density, serum vitamin D levels, and bone metabolism.

Elevated ocular VEMP responses in the absence of a superior semicircular canal dehiscence.

Background: Vestibular evoked myogenic potentials (VEMPs) have an accepted role in the diagnosis of the superior semicircular canal dehiscence (SSCD) syndrome. The current impression is that ocular VEMPs (oVEMPs) are more sensitive than cervical VEMPs (cVEMPs) for detecting a SSCD and that oVEMP testing in response to air conducted sound provides an excellent screening test without risk of radiation exposure from computerized tomography (CT).

Aims/objectives: To report on patients with elevated oVEMP amplitudes but without evidence for a SSCD on multiplanar CT imaging.

Gentamicin Vestibulotoxicity: Further Insights From a Large Clinical Series.

Objective: To review insights gained from a 21-year experience with gentamicin-induced vestibulotoxicity including differences in vestibulotoxicity between single daily dosing (SDD) and multiple daily dosing (MDD) regimens.

Study Design: Retrospective case series.

Setting: Tertiary care center.

Transient Vertigo with Horizontal Nystagmus to Loud Noise and Pressure: Utricular Hydrops or Vestibular Atelectasis?

We present an unusual case of a patient with a positive Tullio phenomenon, brief Valsalva-induced transient horizontal nystagmus, reduced left caloric response, and bilateral vestibulo-ocular reflex loss. This study discusses the pathophysiology and differential diagnosis concerning the suspected pathology for the phenomenon of utricular hydrops or vestibular atelectasis and presents a literature review.

Long-Term Outcomes from Blind Sac Closure of the External Auditory Canal: Our Institutional Experience in Different Pathologies.

Objectives: This study reports long-term results of blind sac closure of the external auditory canal performed for various pathologies, compares the complication rates and the need for revision surgery.

Materials And Methods: This study is a retrospective review. Ninety-six cases of blind sac closure performed for various pathologies were included in this study.

Management of invasive intralabyrinthine cholesteatoma: Can one realistically preserve hearing when disease is medial to the otic capsule?

Purpose: To report our long-term results in surgical management of invasive intralabyrinthine cholesteatoma.

Material And Methods: The study is a case series in a tertiary referral center. Retrospective chart review of all mastoid operations performed for chronic ear disease between 1994 and 2019 at University Health Network, Toronto.

Interdisciplinary integration of nursing and psychiatry (INaP) for the treatment of dizziness.

Objectives: The traditional medical care model of "assess and refer" requires revamping to address the multifaceted needs of patients with chronic dizziness and imbalance by adopting an interdisciplinary approach to care that integrates nursing and psychiatry (INaP). We aim to present a novel interdisciplinary approach that incorporates INaP in the care of patients with chronic dizziness and imbalance.

Methods: Presentation of an interdisciplinary model of care that incorporates INaP provided at the Toronto General Hospital in Toronto, Canada.

Interdisciplinary integration of nursing and psychiatry (INaP) improves dizziness-related disability.

Objectives/hypothesis: The traditional medical care model of "assess and refer" in a sequential fashion fails to recognize the complexities that arise due to overlapping physical and psychiatric comorbidities experienced by patients with chronic dizziness or imbalance, thus resulting in inadequate treatment outcomes. We aimed to evaluate the impact of a novel interdisciplinary approach to care that integrates nursing and psychiatry (INaP) on dizziness-related disability.

Study Design: Retrospective cohort study.

Association Between Catastrophizing and Dizziness-Related Disability Assessed With the Dizziness Catastrophizing Scale.

Importance: Catastrophizing is a maladaptive thought process that involves irrational fear and worry about anticipated or actual symptoms. Although clinically relevant, the role of catastrophizing in patients with chronic dizziness or imbalance has not yet been explored to our knowledge.

Objectives: To validate a measure of dizziness catastrophizing and to assess its association with dizziness-related disability compared with other negative affect constructs (eg, anxiety and depression).
