Factors Associated With Early Computed Tomography Imaging in Children Hospitalized With Severe Orbital Infections.

Objective: We identified factors associated with computed tomographic (CT) imaging within 24 hours of emergency department (ED) presentation in hospitalized children with severe orbital infections.

Patients And Methods: A multicenter retrospective cohort study was conducted that included children aged 2 months to 18 years between 2009 and 2018 who were admitted to the hospital with severe orbital infections, including periorbital and orbital cellulitis. Multivariable modified Poisson regression was used to identify possible factors associated with receiving a CT scan within 24 hours of ED presentation.

Intraoperative changes in large-scale thalamic circuitry following laser ablation of hypothalamic hamartomas.

Background And Objectives: Gelastic seizures due to hypothalamic hamartomas (HH) are challenging to treat, in part due to an incomplete understanding of seizure propagation pathways. Although magnetic resonance imaging-guided laser interstitial thermal therapy (MRgLITT) is a promising intervention to disconnect HH from ictal propagation networks, the optimal site of ablation to achieve seizure freedom is not known. In this study, we investigated intraoperative post-ablation changes in resting-state functional connectivity to identify large-scale networks associated with successful disconnection of HH.

Surgical outcomes in children with drug-resistant epilepsy and hippocampal sclerosis.

Background: Hippocampal sclerosis (HS) is a common surgical substrate in adult epilepsy surgery cohorts but variably reported in various pediatric cohorts.

Objective: We aimed to study the epilepsy phenotype, radiological and pathological variability, seizure and neurocognitive outcomes in children with drug-resistant epilepsy and hippocampal sclerosis (HS) with or without additional subtle signal changes in anterior temporal lobe who underwent surgery.

Methods: This retrospective study enrolled children with drug-resistant focal epilepsy and hippocampal sclerosis with or without additional subtle T2-Fluid Attenuated Inversion Recovery (FLAR)/Proton Density (PD) signal changes in anterior temporal lobe who underwent anterior temporal lobectomy with amygdalohippocampectomy.

Long-term clinical and radiological trajectories of craniocervical vasculopathy in children with PHACE syndrome.

Aim: To describe the rates of stroke and craniocervical vasculopathy progression in children with posterior fossa malformations, hemangioma, arterial anomalies, coarctation of the aorta/cardiac defects, and eye abnormalities (PHACE) syndrome.

Method: A single-center, retrospective natural history study of children with PHACE syndrome. Clinical and sequential neuroimaging data were reviewed to study the characteristics and progression of vasculopathy and calculate the rates of arterial ischemic stroke (AIS) and transient ischemic stroke (TIA).
