Safety of emergency endoscopic endonasal surgery in COVID-positive patients with hemorrhagic complications of pituitary region tumors: A case report and review of the literature.
Surg Neurol Int
December 2024
Department of Neurosurgery Westchester Medical Center, Valhalla, New York, United States.
Background: Pituitary apoplexy (PA) is a rare, life-threatening clinical syndrome that occurs in response to acute ischemic infarction or hemorrhage of a pituitary adenoma. We report two cases of sudden neurologic and visual decline in patients with pituitary region masses in coronavirus disease (COVID)-positive patients with a focus on potential pathophysiological mechanisms and a safe approach to treatment.
Case Description: Case one is a 58-year-old male presenting with sudden-onset headache and visual disturbance.

From the Institute of Neurointervention (C. Hecker, C. Hufnagl, A.O., C.J.G., M.K-O.), Paracelsus Medical University, Salzburg, Austria
Background And Purpose: This animal study was designed to evaluate in vivo the acute and short-term safety and efficacy of the new Artisse intrasaccular device (ISD) for aneurysm occlusion and to gain knowledge about the behavior in the aneurysms.
Materials And Methods: The device was implanted in 7 white New Zealand rabbits with bifurcation aneurysms. Immediate and 90-day angiographic follow-up as well as histologic and scanning electron microscope imaging were evaluated.
Selective otolithic dysfunction in patients presenting with acute spontaneous vertigo: consideration based on MRI.
Front Neurol
December 2024
Dizziness Center, Clinical Neuroscience Center, Seoul National University Bundang Hospital, Seongnam, Republic of Korea.
Objective: Acute unilateral peripheral vestibulopathy or vestibular neuritis (AUPV/VN) manifests as acute onset vertigo, often accompanied by nausea, vomiting, and moderate gait instability. It is suspected when vestibular hypofunction is documented on video-head impulse (video-HITs) and caloric tests in the presence of contralesionally beating horizontal-torsional nystagmus. Herein, we report patients presenting with acute vestibular syndrome (AVS) showing selective otolithic dysfunction in the presence of normal caloric and video-HITs and abnormal enhancement of the peripheral vestibular structures on MRI.

Department of Hematology, Shengli Oilfield Central Hospital, Dongying, Shandong 257000, P.R. China.
The FAT atypical cadherin 1 (FAT1) gene is the ortholog of the fat gene and encodes the protocadherin FAT1. FAT1 belongs to the cadherin superfamily, a group of full-length membrane proteins that contain cadherin-like repeats. In various types of human cancer, FAT1 is one of the most commonly mutated genes, and is considered to be an emerging cancer biomarker and a potential target for novel therapies.
