Post‐COVID‐19 Benign Paroxysmal Positional Vertigo

Case Reports in Medicine, Volume 2021, Issue 1, 2021., 2021
Background. COVID‐19 is a disease caused by a new strain of coronavirus (SARS‐COVID‐19). The WHO first learned about this new virus on December 31, 2019, following a report on a group of cases of “viral pneumonia” in Wuhan, People’s Republic of China, and declared a pandemic in March 2020.

Prediction of the Effect of Adaptation and Active HB Mechanics on Prestin-Based Amplification Using a Macroscopic Model of the Cochlea [PDF]

, 2011
Introduction: Negative social evaluation is associated with psychopathology. Given the frequency of evaluation through increasingly prevalent virtual social networks, increased understanding of the effects of this social evaluation is urgently required ...

A mathematical model for top-shelf vertigo: the role of sedimenting otoconia in BPPV [PDF]

, 2003
Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical disorder of the vestibular system in which calcite particles called otoconia interfere with the mechanical functioning of the fluid-filled semicircular canals normally used to sense rotation ...

Effect of Vitamin D Deficiency on the Occurrence and Recurrence of Benign Paroxysmal Positional Vertigo: A Narrative Review [PDF]

Kirkuk Journal of Medical Sciences
Benign paroxysmal positional vertigo (BPPV) is a short-lived attack of rotatory vertigo provoked by certain head movements. The most acceptable theories for its pathogenesis are canalithiasis and cupulolithiasis as a result of the detachment of otoconia ...

Development of a dynamic virtual reality model of the inner ear sensory system as a learning and demonstrating tool [PDF]

, 2009
In order to keep track of the position and motion of our body in space, nature has given us a fascinating and very ingenious organ, the inner ear. Each inner ear includes five biological sensors - three angular and two linear accelerometers - which ...

Role of Vestibular Evoked Myogenic Potentials as an Indicator of Recovery in Patients with Benign Paroxysmal Positional Vertigo

Acta Clinica Croatica, 2017
Ocular vestibular evoked myogenic potentials (oVEMP) and cervical VEMP (cVEMP) are newer diagnostic methods, which allow an insight into the otolith senses.

Residual dizziness after successful repositioning maneuver for idiopathic benign paroxysmal positional vertigo: a review

Audiology Research, 2017
The benign paroxysmal positional vertigo (BPPV) is a vestibular disorder cause of vertigo. The BPPV may be corrected mechanically by repositioning maneuvers but even after successful maneuvers, some patients report residual dizziness for a certain period

Exocytosis in mouse vestibular Type II hair cells shows a high‐order Ca2+ dependence that is independent of synaptotagmin‐4

Physiological Reports, Volume 8, Issue 14, July 2020., 2020
Here we show that the coupling between neurotransmitter release at the ribbon synapses of mature vestibular Type II hair cells display a high‐order dependence on calcium influx. The calcium dependence was not affected by an absence of the calcium‐sensing synaptic molecule synaptotagmin‐4, which has been shown to be involved in establishing the linear ...

Histopathological changes to the peripheral vestibular system following meningitic labyrinthitis

Laryngoscope Investigative Otolaryngology, Volume 5, Issue 2, Page 256-266, April 2020., 2020
Abstract Objective While cochlear ossification is a common sequalae of meningitic labyrinthitis, less is known about the effects of meningitis on peripheral vestibular end organs. Herein, we investigate histopathologic changes in the peripheral vestibular system and cochlea in patients with a history of meningitic labyrinthitis.

The Tangential Nucleus Controls a Gravito-inertial Vestibulo-ocular Reflex [PDF]

, 2014
Whilst adult vertebrates sense changes in head position using two classes of accelerometer, at larval stages zebrafish lack functional semicircular canals and rely exclusively on their otolithic organs to transduce vestibular information.
