Detection of visual field defects using Eye Movement Pediatric Perimetry in children with intracranial lesions: feasibility and applicability

open access: yesHeliyon, 2022
The study aimed at evaluating the feasibility of Eye Movement Pediatric Perimetry (EMPP) among children in detecting Visual Field Defects (VFDs) associated with Intracranial Lesions (IL).

Nystagmus intensity and direction in bow and lean test: an aid to diagnosis of lateral semicircular canal benign paroxysmal positional vertigo [PDF]

open access: yesActa Otorhinolaryngologica Italica, 2016
L’obiettivo è stato valutare bed side l’intensità e la direzione del nistagmo (NID) nelle due differenti posizioni del “bow and lean test” (BLT) per differenziare la forma geotropa dalla forma apogeotropa e determinare il lato affetto in caso di ...

Slowed Saccadic Reaction Times in Seemingly Normal Parts of Glaucomatous Visual Fields

open access: yesFrontiers in Medicine, 2021
Purpose: In eye movement perimetry, peripheral stimuli are confirmed by goal-directed eye movements toward the stimulus. The saccadic reaction time (SRT) is regarded as an index of visual field responsiveness, whereas in standard automated perimetry (SAP)

Supplemental CO2 improves oxygen saturation, oxygen tension, and cerebral oxygenation in acutely hypoxic healthy subjects

open access: yesPhysiological Reports, 2020
Oxygen is viewed in medicine as the sole determinant of tissue oxygenation, though carbon dioxide homeostasis is equally important and clinically often ignored. The aims of this study were as follows: (a) to examine the effects of different acute hypoxic

Vertebral artery compression of medulla oblongata causing isolated symptom of dizziness: two case reports

open access: yesThe Egyptian Journal of Otolaryngology, 2020
Background Symptomatic medulla oblongata compressing lesions due to dilated vertebral artery are rare in the literature. The symptoms are extremely heterogeneous and not correlated to the severity of compression in many cases.

Electrically evoked auditory brainstem response in cochlear implantation: what you need to know (short review)

open access: yesThe Egyptian Journal of Otolaryngology, 2022
Background Electrically evoked auditory brainstem response (E-ABR) is an evoked potential recorded from the auditory nerve in response to electric stimulation. It is considered a short latency evoked potential. It plays a vital role, especially after the

Postoperative audiovestibular assessment of obstructive sleep apnea patients

open access: yesThe Egyptian Journal of Otolaryngology, 2020
Background In obstructive sleep apnea syndrome, the impact of hypoxia on different body systems is of utmost importance. Brainstem is greatly sensitive to the effects of hypoxia including auditory and vestibular nuclei. Our aim in the current study is to

Use of an Extra-Tympanic Membrane Electrode to Record Cochlear Microphonics with Click, Tone Burst and Chirp Stimuli

open access: yesAudiology Research, 2021
This study determined electrocochleography (ECochG) parameter settings to obtain cochlear microphonics (CM) with less invasive flexible extra-tympanic membrane electrodes. In 24 adult normal-hearing subjects, CMs were elicited by presenting click stimuli

Vestibular loss disrupts visual reactivity in the alpha EEG rhythm

open access: yesNeuroImage: Clinical, 2023
The alpha rhythm is a dominant electroencephalographic oscillation relevant to sensory-motor and cognitive function. Alpha oscillations are reactive, being for example enhanced by eye closure, and suppressed following eye opening.

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)
