Putting the Puzzle Together: Case Report of Parinaud Syndrome in a Pediatric Patient.
J Binocul Vis Ocul Motil
January 2025
Department of Ophthalmology, Vanderbilt Eye Institute, Nashville, Tennessee.
Parinaud syndrome, also known as dorsal midbrain syndrome, is a condition affecting the dorsal midbrain region of the brainstem that presents with a triad of ophthalmic clinical findings, including upgaze paresis, convergence retraction nystagmus, and light-near dissociation. This case report will discuss the clinical presentation of Parinaud syndrome in a four-year-old patient who was seen in an out-patient clinic for intermittent exotropia 5 months after a suboccipital craniotomy resection of a pineal mass and ventriculoperitoneal (VP) shunt placement for associated hydrocephalus. Current literature is relatively sparse regarding the presentation of Parinaud syndrome in the pediatric population, with little known about prognosis and potential for recovery.

Department of Ultrasound, The Second Affiliated Hospital of Shandong First Medical University, Tai'an, China.
Objective: Elevated intracranial pressure (ICP), a common complication in traumatic brain injuries (TBI), can lead to optic nerve sheath diameter (ONSD) enlargement and flow spectrum changes from the internal carotid artery (ICA) to middle cerebral artery (MCA). This study will investigate the use of Cervical-Cerebral Arterial Ultrasound (CCAU) for non-invasive ICP assessment and evaluating the related indices' clinical utility in TBI patients with decompressive craniotomy (DC).
Methods: ONSD and flow spectrum changes were measured within 24 h after DC in 106 patients via ultrasonic ONSD measurement and CCAU, simultaneously.
Case Report: First use of dental bisphenol A-glycidyl methacrylate composite without UV light polymerization for repair of iatrogenic CSF leak following a frontal craniotomy plus tumor resection.

January 2025
Department of Surgery and Specialties, Faculty of Medicine and Pharmaceutical Sciences, University of Douala, Douala, Cameroon.
Objective: This study aimed to evaluate the efficacy and safety of bisphenol A-glycidyl methacrylate (bis-GMA) without UV light polymerization for the repair of refractory iatrogenic cerebrospinal fluid (CSF) leaks with large skull base defects.
Background: CSF leakage remains a common complication after neurosurgical interventions with a substantial resultant impact on morbidity and increased healthcare costs. The management of refractory CSF leaks with large skull base defects remains challenging.
Visual Outcomes after Suprasellar Meningioma Resection: A Retrospective Cohort Study and a Machine Learning-Based Predictive Model.

Department of Neurosurgery, Tehran University of Medical Sciences, Imam Khomeini Hospital Complex (IKHC), Tehran, Iran.
In this research, the authors provide a retrospective cohort study of 82 patients with suprasellar meningiomas to identify predictors of the visual outcome following surgery. We also conducted a matched retrospective case-control analysis. This retrospective cohort study included all patients who underwent craniotomy for surgical excision of suprasellar meningiomas at our institution between January 2016 and March 2022.

Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona, United States.
The abducens nerve has a long, serpentine subarachnoid course with complex topographical relationships, rendering abducens nerve palsy the most common ocular motor cranial nerve palsy in adults and second most common in pediatric patients, with anatomical variants reported in the literature. Preoperative awareness of abducens nerve variant anatomy may help prevent inadvertent intraoperative injury. This study is a case report with a review of the abducens nerve anatomy and variants.
