Objective: Describe the clinical characteristics, treatment strategies, and outcome data of children with papilledema associated with Lyme disease at a large tertiary care pediatric hospital.

Methods: Retrospective cohort study of children 1-18 years old who received care at our institution between 1995 and 2019 with concurrent diagnoses of papilledema and Lyme disease. Data were abstracted from records and prospective family surveys.

Quadriparesis and paraparesis following chimeric antigen receptor T-cell therapy in children and adolescents.

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.

Vaginal Compared With Oral Misoprostol Induction at Term: A Cluster Randomized Controlled Trial.

Objective: To evaluate efficacy in achieving vaginal delivery with a standardized vaginal compared with oral misoprostol regimen for labor induction at term.

Methods: In this single-center, cluster randomized trial, we randomized induction method by week among individuals with gestational age of 37 weeks or more, cervical dilation of 2 cm or less, intact membranes, and indication for delivery to either oral (100 micrograms every 4 hours for up to two doses), or vaginal (25 micrograms every 3 hours for up to five doses) misoprostol regimens, followed by a standardized oxytocin protocol. Individuals with an antepartum stillbirth, major fetal anomalies, malpresentation, ruptured membranes, nonreassuring fetal status, or contraindication to prostaglandin were excluded.

A personalized protocol for prescribing opioids after cesarean delivery: leveraging the electronic medical record to reduce outpatient opioid prescriptions.

Background: Although cesarean delivery is the most common surgery performed in the United States, prescribing practices for analgesia vary. Strategies to manage postpartum pain have mostly focused on the immediate postpartum period when patients are still admitted to the hospital. At discharge, most providers prescribe a fixed number of opioid tablets.

Early Measures of TBI Severity Poorly Predict Later Individual Impairment in a Rat Fluid Percussion Model.

Background: Multiple measures of injury severity are suggested as common data elements in preclinical traumatic brain injury (TBI) research. The robustness of these measures in characterizing injury severity is unclear. In particular, it is not known how reliably they predict individual outcomes after experimental TBI.

Neurological and Psychological Sequelae Associated With Multisystem Inflammatory Syndrome in Children.

Importance: Acute neurological involvement occurs in some patients with multisystem inflammatory syndrome in children (MIS-C), but few data report neurological and psychological sequelae, and no investigations include direct assessments of cognitive function 6 to 12 months after discharge.

Objective: To characterize neurological, psychological, and quality of life sequelae after MIS-C.

Design, Setting, And Participants: This cross-sectional cohort study was conducted in the US and Canada.

Update on Central Nervous System Effects of HIV in Adolescents and Young Adults.

Purpose Of Review: : Behaviorally acquired (non-perinatal) HIV infection during adolescence and young adulthood occurs in the midst of key brain developmental processes such as frontal lobe neuronal pruning and myelination of white matter, but we know little about the effects of new infection and therapy on the developing brain.

Recent Findings: Adolescents and young adults account for a disproportionately high fraction of new HIV infections each year. Limited data exist regarding neurocognitive performance in this age group, but suggest impairment is at least as prevalent as in older adults, despite lower viremia, higher CD4 + T cell counts, and shorter durations of infection in adolescents/young adults.

Race and the emergency department management of febrile seizures.

To determine if racial disparities exist in the management of febrile seizures in a large pediatric emergency department (ED), We performed a retrospective cross-sectional analysis of children 6 months to 6 years-old who presented to the ED with a febrile seizure over a 4-year period. Multivariate logistic regression models were built to examine the association between race and the primary outcome of neuroimaging, and secondary outcomes of hospital admission and abortive anticonvulsant prescription at ED discharge. There were 980 ED visits during the study period.

The Impact of C1 Anterior Arch Preservation on Spine Stability After Odontoidectomy: Systematic Review and Meta-Analysis.

Background: Odontoidectomy for symptomatic irreducible ventral brainstem compression at the craniovertebral junction may result in spine instability requiring subsequent instrumentation. There is no consensus on the importance of C1 anterior arch preservation in prevention of iatrogenic instability. We conducted a systematic review of the impact of C1 anterior arch preservation on postodontoidectomy spine stability.

Clinical Reasoning: A 12-Month-Old Male Child With Staring Episodes, Ataxia, and Right-sided Weakness.

, 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.

C1 Lateral Mass Screw Placement Through Endonasal Corridor for Purpose of O-C1 Fusion: Morphometric Analysis in Cadaveric Specimens.

Background: Odontoidectomy may pose some risks for O-C1 and/or C1-C2 instability, with previous authors reporting techniques for endonasal C1-C2 fusion. However, no technique for endonasal O-C1 fusion currently exists. We sought to describe the feasibility of endonasal anterior C1 (AC1) screw placement for endonasal O-C1 fusion.

Postinjury Treatment to Mitigate the Effects of Aeromedical Evacuation After Traumatic Brain Injury in a Porcine Model.

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.

Differentiating Bell's Palsy From Lyme-Related Facial Palsy.

Background And Objectives: To describe the etiology and clinical course of pediatric acute-onset unilateral peripheral facial palsy (FP), to define factors that distinguish Bell's palsy from Lyme-related FP (LRFP), and to determine if early corticosteroid use impacts facial strength recovery in Bell's palsy or LRFP.

Methods: Retrospective cohort study of children 1 to 18 years old who received clinical care within our pediatric clinical care network (Lyme-endemic region) between 2013 and 2018 for acute-onset unilateral peripheral FP.

Results: The study included 306 children; 82 (27%) had LRFP, 209 (68%) had Bell's palsy, and 15 (5%) had FP of different etiology.

Objectives: To define the incidence and characteristics of influenza-associated neurologic complications in a cohort of children hospitalized at a tertiary care pediatric hospital with laboratory-confirmed influenza and to identify associated clinical, epidemiologic, and virologic factors.

Study Design: This was an historical cohort study of children aged 0.5-18.

Late Diagnosis of Congenital Toxoplasmosis with Macrocephaly in Dizygotic Twins after Incidental Detection of Leukocoria: A Case Report.

Untreated congenital toxoplasmosis remains an important cause of neurologic and ocular disease worldwide. However, congenitally infected infants may not have signs and symptoms their physicians recognize, leading to delayed diagnosis and missed opportunities for treatment. We describe a pair of twins diagnosed with congenital toxoplasmosis at 11 months of age following incidental detection of leukocoria in one twin.

Deficits in pattern separation and dentate gyrus proliferation after rodent lateral fluid percussion injury.

It has been demonstrated that adult born granule cells are generated after traumatic brain injury (TBI). There is evidence that these newly generated neurons are aberrant and are poised to contribute to poor cognitive function after TBI. Yet, there is also evidence that these newly generated neurons are important for cognitive recovery.

Intracranial Hypertension in Multisystem Inflammatory Syndrome in Children.

Multisystem inflammatory syndrome in children (MIS-C) is characterized by fever and multiorgan system dysfunction. Neurologic complications of MIS-C are not well described. We present 4 patients with MIS-C who had intracranial hypertension and discuss the unique management considerations when this occurs concurrently with significant myocardial dysfunction.

Remote and Persistent Alterations in Glutamate Receptor Subunit Composition Induced by Spreading Depolarizations in Rat Brain.

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.

Suppurative Intracranial Complications of Pediatric Sinusitis: A Single-Center Experience.

Background: Suppurative intracranial complications of sinusitis are rare events in children and can lead to harmful neurologic sequelae and significant morbidity. We sought to review the presentation and management of patients admitted at our hospital with these conditions.

Methods: This was a retrospective study of pediatric patients admitted to a quaternary children's hospital from 2007 to 2019 for operative management of sinusitis with intracranial extension.
