In the present study, the value of cervical vestibular-evoked myogenic potential (cVEMP) as a predictive factor for residual dizziness after recovery of benign paroxysmal positional vertigo (BPPV) was evaluated.
Benign paroxysmal positional vertigo (BPPV) is the most frequent peripheral vestibular disorder and is particularly seen among older patients suffering from vertigo. The brief vertigo attacks in and imbalance symptoms of BPPV are caused by freely floating otoconia within the semicircular canals. The aim of this prospective study was to evaluate the role of oxidative stress, using native thiol/disulfide (SH/SS) homeostasis as a novel indicator, in the etiology of BPPV.
Dizziness is one of the most common causes of medical visits. Management of the dizzy patient may be challenging both for the general practitioner, in emergency departments, and special clinics, as behind a seemingly homogeneous clinical presentation several very different etiologies may occur. Research of the last two century enriched our knowledge about physiology and pathophysiology of the vestibular system. Much knowledge is now available about the labyrinth being able to sense head motions and gravity,...
Head motions cause transient vertigo in patients with benign paroxysmal positional vertigo (BPPV) and may reduce visual ability.
Vertigo is a common symptom of multiple sclerosis (MS) that can be caused by a central or peripheral involvement of the vestibular pathways. Magnetic Resonance Imaging (MRI) is commonly used to evaluate progression of MS but is not sensitive enough to detect small lesions. Vestibular evoked myogenic potentials (VEMPs) are commonly used to evaluate function of vestibular-cochlear pathways. The aim of this literature review is to evaluate the role of VEMPs in patients with MS-related vertigo as a tool to dete...
To describe an unusual patient reaction to maneuvers used in the treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV) that we termed the "Tumarkin-like phenomenon".
The aim of this investigation was to evaluate the association between posterior channel benign paroxysmal positional vertigo (BPPV) and trauma that is frequently experienced by American football players.
To describe the clinical features of benign paroxysmal positional vertigo (BPPV) in children.
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of dizziness. There is some evidence that osteoporosis is a risk factor for BPPV.
To describe a variant of posterior canal benign paroxysmal positional vertigo (BPPV).
To describe a variant of posterior canal benign paroxysmal positional vertigo (BPPV).
BACKGROUND The aim of this study was to investigate the correlations of calcium voltage-gated channel subunit alpha1 A (CACNA1A) gene polymorphisms with benign paroxysmal positional vertigo (BPPV). MATERIAL AND METHODS A total of 120 BPPV patients and 60 healthy controls were enrolled according to the diagnostic criteria in the Guideline of Diagnosis and Treatment of Benign Paroxysmal Positional Vertigo (2017). Clinical and biochemical data were collected, the rs2074880 (T/G) polymorphisms in the CACNA1A ge...
To evaluate the diagnostic value of vestibular evoked myogenic potentials (VEMPs) in the assessment of brainstem function integrity in patients with amyotrophic lateral sclerosis (ALS).
To determine whether cervical vestibular evoked myogenic potentials (cVEMPs) are predictive of hearing preservation in patients undergoing vestibular schwannoma removal through middle fossa craniotomy approach.
Vestibular-evoked myogenic potential (VEMP) is commonly conducted with air-conducted (AC) stimuli whose intensity may exceed the prudential levels of acoustic exposure in susceptible subjects.
Dizziness can be due to pathology from multiple physiologic systems, the most common being vestibular. Dizziness may be categorized as vertigo, disequilibrium, lightheadedness, or oscillopsia. Vertigo is an illusion of motion often caused by asymmetrical vestibular input to the brainstem. To evaluate vertigo, it is essential to include the symptom's quality, timing, frequency, trigger, influence from positional changes, and other associations from the history. Oculomotor, otologic, balance testing, position...
To determine whether patients presenting to the emergency department (ED) with possible benign paroxysmal positional vertigo (BPPV) are managed in accordance with best practice guidelines, and whether physiotherapists are involved in their care.
The vestibular evoked myogenic potential triggered by galvanic vestibular stimulation (galvanic-VEMP) has been used to assess the function of the vestibulospinal motor tract and is a candidate biomarker to predict and monitor the human T-cell lymphotropic virus type 1 (HTLV-1) associated myelopathy (HAM). This study determined the agreement and reliability of this exam.
Canalith jam refers to a condition caused by an otolithic clump blocked inside a semicircular canal, generally provoked by canalith repositioning procedure. We describe the first case of spontaneous canalith jam mimicking an acute vestibular deficit.
Dizziness is a common chief complaint with an extensive differential diagnosis that includes both benign and serious conditions. Physicians must distinguish the majority of patients who suffer from self-limiting conditions from those with serious illnesses that require acute treatment. The preferred approach to the diagnosis of an acutely dizzy patient emphasizes different aspects of the history to guide a focused physical examination, with the goal of differentiating benign peripheral vestibular conditions...
There is a growing concern among the scientific community about the possible detrimental effects of signal levels used for eliciting vestibular evoked myogenic potentials (VEMPs) on hearing. A few recent studies showed temporary reduction in amplitude of otoacoustic emissions (OAE) after VEMP administration. Nonetheless, these studies used higher stimulus levels (133 and 130 dB peak equivalent sound pressure level [pe SPL]) than the ones often used (120 to 125 dB pe SPL) for clinical recording of VEMP. Ther...
Acute vertigo is a common problem in emergency departments. However, clinical strategies of acute vertigo care vary among care providers. The aim of the study was to investigate differences in diagnosis [Dix-Hallpike test, the head impulse, nystagmus, and the test of skew (HINTS) procedure, and imaging modalities] and treatment (pharmacological treatments and the Epley maneuver) by otolaryngologists and non-otolaryngologists in emergency medicine settings. We used a multicenter case-based survey for the stu...
Simultaneous four-channel recording of bilateral cervical and ocular vestibular-evoked myogenic potentials in response to stimulation by forehead bone-conducted vibration: Our experience in 20 healthy adults.
Various vestibular stimuli, including air-conducted sound (ACS), bone-conducted vibration (BCV), and galvanic vestibular stimulation (GVS), can be used to elicit vestibular-evoked myogenic potential (VEMP). VEMP obtained from the sternocleidomastoid (SCM) muscle is called cervical VEMP (cVEMP), while that recorded at extraocular muscles is termed ocular VEMP (oVEMP). cVEMP was first recognized as fundamental in determining the sacculo-collic reflex (SCR) pathway in the mid-1990s. In the mid-2000s, oVEMP was...
We recorded evoked potentials (EPs) from over the posterior fossa and in parallel ocular vestibular evoked myogenic potentials (OVEMPs) during visuo-vestibular stimulation in a sample of 7 male and 11 female human subjects. In 9 of the 18 subjects we were able to record EPs reliably in the form of an early biphasic positive-negative wave with latencies about 12 and 17 ms ipsilateral to head acceleration direction (P12-N17) and a slightly later, contralateral, biphasic positive-negative wave with latencies a...
