Immune effector cell-associated neurotoxicity syndrome (ICANS) is a common but potentially severe adverse event associated with chimeric antigen receptor T-cell (CART) therapy, characterized by the development of acute neurologic symptoms following CART infusion. ICANS encompasses a wide clinical spectrum typified by mild to severe encephalopathy, seizures, and/or cerebral edema. As more patients have been treated with CART, new ICANS phenomenology has emerged.

Article Synopsis
  • A study analyzed pediatric emergency department visits for febrile seizures in children aged 6 months to 6 years over 4 years, focusing on racial disparities in management.
  • The research found no racial differences in neuroimaging or hospital admissions, but black children on Medicaid were significantly less likely to receive abortive anticonvulsants compared to non-black peers.
  • These findings suggest a potential need for standardized guidelines on anticonvulsant prescriptions to address and reduce racial disparities in treatment.

Article Synopsis
  • A systematic review was conducted to evaluate the effects of preserving the C1 anterior arch during odontoidectomy on spine stability and post-treatment outcomes in patients with ventral brainstem compression.
  • The analysis included 27 studies with 462 patients, showing a significant reduction in spine instability when the C1 anterior arch was preserved, along with overall positive clinical improvement in 78.8% of cases.
  • The results indicated that both transoral approaches (TOA) and endoscopic endonasal approaches (EEA) yield similar outcomes, although EEA was associated with higher intraoperative cerebrospinal fluid leaks.

, or raccoon roundworm, is a rare cause of eosinophilic meningoencephalitis with historically poor clinical outcomes. Symptoms of neural larval migrans begin approximately 2-4 weeks after ingestion with fatigue, nausea, fever, and lethargy and then rapidly progress to weakness, incoordination, ataxia, seizures, altered mental status, and finally coma. Only 31 other cases of CNS neural larval migrans have been reported, with more than 25% being lethal.

Introduction: Early aeromedical evacuation after traumatic brain injury (TBI) has been associated with worse neurologic outcomes in murine studies and military populations. The goal of this study was to determine if commonly utilized medications, including allopurinol, propranolol, or tranexamic acid (TXA), could mitigate the secondary traumatic brain injury experienced during the hypobaric and hypoxic environment of aeromedical evacuation.

Methods: Porcine TBI was induced via controlled cortical injury.

Article Synopsis
  • The study focused on children hospitalized with infective endocarditis, examining the occurrence and types of acute neurologic complications, along with associated risk factors.
  • A retrospective analysis showed that 34% of children experienced neurologic issues, such as intracranial hemorrhage and ischemic strokes, occurring about 4.5 days after initial symptoms of infective endocarditis.
  • The findings suggest a need for routine neurologic evaluation and imaging in these cases, as many complications could go undetected, and the study calls for further prospective research to improve early identification and management.

Spreading depolarizations (SDs) are massive breakdowns of ion homeostasis in the brain's gray matter and are a necessary pathologic mechanism for lesion development in various injury models. However, injury-induced SDs also propagate into remote, healthy tissue where they do not cause cell death, yet their functional long-term effects are unknown. Here we induced SDs in uninjured cortex and hippocampus of Sprague-Dawley rats to study their impact on glutamate receptor subunit expression after three days.
