Objective: Seizures are one of the most common neurologic complications seen in a neonate. Historically, phenobarbital has been the agent of choice, but can lead to adverse neurologic outcomes, which has contributed to the use of other agents. Levetiracetam has proven great efficacy with an excellent safety profile in older patients, causing interest of its use in neonates. The objective of this study was to determine if levetiracetam would provide similar neonatal seizure resolution rates as phenobarbital.
Methods: The study was a single-center, retrospective, cohort study from August 1, 2020 to August 31, 2022 investigating the efficacy and safety of using levetiracetam compared with phenobarbital as a first line treatment for neonatal seizures. The primary outcome was to assess overall seizure resolution after administration of levetiracetam or phenobarbital, without addition of a second antiseizure medication.
Results: There were 87 patients included in the study. Fifteen neonates (27.78%) achieved seizure resolution with phenobarbital compared with 9 neonates (27.27%) who received levetiracetam first line (p = 0.959). Neonates who received phenobarbital had higher rates of adverse effects. Neonates who received a benzodiazepine prior to administration of levetiracetam had lower seizure resolution rates (p = 0.021).
Conclusions: These findings suggest there is no difference in using phenobarbital over levetiracetam to achieve complete seizure resolution in a neonate. Higher rates of adverse events were seen in the phenobarbital group. The use of a benzodiazepine prior to administration of levetiracetam may reduce the efficacy of levetiracetam.

Human lactate dehydrogenase A (LDHA) is a homotetrameric isozyme involved in the conversion of glyoxylate into oxalate in the cytosol of liver cells (hepatocytes) and partially responsible for the overproduction of oxalate in patients with the rare disease called primary hyperoxaluria (PH). Recently, LDHA inhibition has been validated as a safe therapeutic method to try to control the PH disease. Stiripentol (STP) is an approved drug used in the treatment of seizures associated with Dravet's syndrome (a severe form of epilepsy in infancy) which, in addition, has been drawing interest in recent years also for potentially treating PH, due to its LDHA inhibitory activity.

Background: The role of imaging in autoimmune encephalitis (AIE) remains unclear, and there are limited data on the utility of magnetic resonance imaging (MRI) to diagnose, treat, or prognosticate AIE.
Purpose: To evaluate whether MRI is a diagnostic and prognostic marker for AIE and assess its efficacy in distinguishing between various AIE subtypes.
Material And Methods: We analyzed data from 96 AIE patients from our prospective autoimmune registry.
Unlabelled: Mild hypoxic-ischemic encephalopathy is common in neonates with no evidence-based therapies, and 30-40% of patients experience adverse outcomes. The nature and progression of mild injury is poorly understood. Thus, we studied the evolution of mild perinatal brain injury using longitudinal two-photon imaging of transgenic fluorescent proteins as a novel readout of neuronal viability and activity at cellular resolution.

Introduction: This study investigated low-density scalp electrical source imaging of the ictal onset zone and interictal spike ripple high-frequency oscillation networks using source coherence maps in the pediatric epilepsy surgical workup. Intracranial monitoring, the gold standard for determining epileptogenic zones, has limited spatial sampling. Source coherence analysis presents a promising new non-invasive technique.
