Cerebellar Syndrome From Proton Pump Inhibitor-Induced Hypomagnesemia: Two Reversible but Relapsing Cases. [PDF]

Case Rep Otolaryngol
Introduction Cerebellar syndromes are rare yet potentially serious presentations in the emergency department, requiring timely diagnosis and intervention. The differential diagnosis is wide, encompassing stroke, multiple sclerosis, toxic reactions, and metabolic imbalances such as hypomagnesemia.

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 ...

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

Subjective visual vertical with the bucket method in Brazilian healthy individuals

Brazilian Journal of Otorhinolaryngology
INTRODUCTION: The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, Volume 309, Issue 4, Page 912-929, April 2026.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Electrical Control of the Transduction Channels’ Gating Force in Mechanosensory Hair Cells

Advanced Science, Volume 13, Issue 16, 18 March 2026.
The inner ear's hair cells rely on mechanosensitive ion channels to convert vibrations of their hair‐bundle into electrical signals. We show that varying the electrical potential (U) across the sensory epithelium modulates a key determinant of mechanosensitivity—the gating force (FG)—by modulating the gating swing (d), ranging from the size of the ...

An Electron Microscopic Study of the Otolithic Membrane

Practica Oto-Rhino-Laryngologica, 1978
Morphological studies were made of the otolithic membrane in its normal and pathological states in guinea pig, mice and squirrel monkey using scanning and transmission electron microscopes.The otolithic membrane normally consists of three layers; the first layer, situated nearest the endolymph, is an otoconial layer wherein otoconia of calcite form of ...

Otopathologic Patterns of Cellular Degeneration in the Peripheral Vestibular Organ Secondary to Head Trauma

The Laryngoscope, Volume 135, Issue 10, Page 3859-3866, October 2025.
This study examines vestibular degeneration following head trauma, comparing cases with and without fractures. Histopathological analysis of 26 temporal bones showed more severe damage in nonfracture cases, particularly in Scarpa's ganglion cells and vestibular hair cells.

Otolith‐based species identification in the killifish Aphaniops (Teleostei; Cyprinodontiformes; Aphaniidae) using both morphometry and wavelet analysis

Acta Zoologica, Volume 106, Issue 3, Page 291-308, July 2025.
Abstract The killifish genus Aphaniops consists of nine species distributed in Eastern Africa and the Middle East. However, distinguishing these species from each other based on morphological traits is challenging. Here we investigate the utility of otoliths (sagittae) in distinguishing between A. dispar, A. ginaonis, A. hormuzensis, A.
