RESUMEN
BACKGROUND AND OBJECTIVES: There are limited tools available following cardiac arrest to prognosticate neurologic outcomes. Prior retrospective and single center studies have demonstrated early EEG features are associated with neurologic outcome. This study aimed to evaluate the prognostic value of EEG for pediatric in-hospital cardiac arrest (IHCA) in a prospective, multicenter study. METHODS: This cohort study is a secondary analysis of the ICU-Resuscitation trial, a multicenter randomized interventional trial conducted at 18 pediatric and pediatric cardiac ICUs in the United States. Patients who achieved return of circulation (ROC) and had post-ROC EEG monitoring were eligible for inclusion. Patients < 90 days old and those with pre-arrest Pediatric Cerebral Performance Category (PCPC) scores > 3 were excluded. EEG features of interest included EEG Background Category, and presence of focal abnormalities, sleep spindles, variability, reactivity, periodic and rhythmic patterns, and seizures. The primary outcome was survival to hospital discharge with favorable neurologic outcome. Associations between EEG features and outcomes were assessed with multivariable logistic regression. Prediction models with and without EEG Background Category were developed and receiver operator characteristic curves compared. RESULTS: Of the 1129 patients with an index cardiac arrest who achieved ROC in the parent study, 261 had EEG within 24 h of ROC, of which 151 were evaluable. The cohort included 57% males with a median age of 1.1 years (IQR 0.4, 6.8). EEG features including EEG Background Category, sleep spindles, variability, and reactivity were associated with survival with favorable outcome and survival, (all p < 0.001). The addition of EEG Background Category to clinical models including age category, illness category, PRISM score, duration of CPR, first documented rhythm, highest early post-arrest arterial lactate improved the prediction accuracy achieving an AUROC of 0.84 (CI 0.77-0.92), compared to AUROC of 0.76 (CI 0.67-0.85) (p = 0.005) without EEG Background Category. CONCLUSION: This multicenter study demonstrates the value of EEG, in the first 24 h following ROC, for predicting survival with favorable outcome after a pediatric IHCA.

OBJECTIVE: To describe and assess performance of the Correlate Of Injury to the Nervous system (COIN) index, a quantitative electroencephalography (EEG) metric designed to identify areas of cerebral dysfunction concerning for stroke. METHODS: Case-control study comparing continuous EEG data from children with acute ischemic stroke to children without stroke, with or without encephalopathy. COIN is calculated continuously and compares EEG power between cerebral hemispheres. Stroke relative infarct volume (RIV) was calculated from quantitative neuroimaging analysis. Significance was determined using a two-sample t-test. Sensitivity, specificity, and accuracy were measured using logistic regression. RESULTS: Average COIN values were -34.7 in the stroke cohort compared to -9.5 in controls without encephalopathy (p = 0.003) and -10.5 in controls with encephalopathy (p = 0.006). The optimal COIN cutoff to discriminate stroke from controls was -15 in non-encephalopathic and -18 in encephalopathic controls with >92% accuracy in strokes with RIV > 5%. A COIN cutoff of -20 allowed discrimination between strokes with <5% and >5% RIV (p = 0.027). CONCLUSIONS: We demonstrate that COIN can identify children with acute ischemic stroke. SIGNIFICANCE: COIN may be a valuable tool for stroke identification in children. Additional studies are needed to determine utility as a monitoring technique for children at risk for stroke.

Importance: Morbidity and mortality after pediatric cardiac arrest are chiefly due to hypoxic-ischemic brain injury. Brain features seen on magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) after arrest may identify injury and aid in outcome assessments. Objective: To analyze the association of brain lesions seen on T2-weighted MRI and diffusion-weighted imaging and N-acetylaspartate (NAA) and lactate concentrations seen on MRS with 1-year outcomes after pediatric cardiac arrest. Design, Setting, and Participants: This multicenter cohort study took place in pediatric intensive care units at 14 US hospitals between May 16, 2017, and August 19, 2020. Children aged 48 hours to 17 years who were resuscitated from in-hospital or out-of-hospital cardiac arrest and who had a clinical brain MRI or MRS performed within 14 days postarrest were included in the study. Data were analyzed from January 2022 to February 2023. Exposure: Brain MRI or MRS. Main Outcomes and Measures: The primary outcome was an unfavorable outcome (either death or survival with a Vineland Adaptive Behavior Scales, Third Edition, score of <70) at 1 year after cardiac arrest. MRI brain lesions were scored according to region and severity (0 = none, 1 = mild, 2 = moderate, 3 = severe) by 2 blinded pediatric neuroradiologists. MRI Injury Score was a sum of T2-weighted and diffusion-weighted imaging lesions in gray and white matter (maximum score, 34). MRS lactate and NAA concentrations in the basal ganglia, thalamus, and occipital-parietal white and gray matter were quantified. Logistic regression was performed to determine the association of MRI and MRS features with patient outcomes. Results: A total of 98 children, including 66 children who underwent brain MRI (median [IQR] age, 1.0 [0.0-3.0] years; 28 girls [42.4%]; 46 White children [69.7%]) and 32 children who underwent brain MRS (median [IQR] age, 1.0 [0.0-9.5] years; 13 girls [40.6%]; 21 White children [65.6%]) were included in the study. In the MRI group, 23 children (34.8%) had an unfavorable outcome, and in the MRS group, 12 children (37.5%) had an unfavorable outcome. MRI Injury Scores were higher among children with an unfavorable outcome (median [IQR] score, 22 [7-32]) than children with a favorable outcome (median [IQR] score, 1 [0-8]). Increased lactate and decreased NAA in all 4 regions of interest were associated with an unfavorable outcome. In a multivariable logistic regression adjusted for clinical characteristics, increased MRI Injury Score (odds ratio, 1.12; 95% CI, 1.04-1.20) was associated with an unfavorable outcome. Conclusions and Relevance: In this cohort study of children with cardiac arrest, brain features seen on MRI and MRS performed within 2 weeks after arrest were associated with 1-year outcomes, suggesting the utility of these imaging modalities to identify injury and assess outcomes.

Background and Objectives: Pediatric headaches, including migraine, are a common reason for emergency department (ED) presentation. IV valproic acid (VPA) followed by oral VPA tapers are often used to abort pediatric headache and reduce recurrence, though limited data exist regarding this approach. This study evaluated the effectiveness of IV VPA and oral VPA tapers for the treatment of acute pediatric headaches in the ED in preventing return encounters. Methods: This is a retrospective cohort study of patients aged 5-21 years presenting to a tertiary-care pediatric ED from 2010 to 2016 who received IV VPA for headache or migraine. Primary outcomes were ED disposition, percent pain reduction (initial vs 2-hour patient-reported pain score [10-point scale]), and return for acute headache treatment within 1 month. Results: A total of 486 ED encounters were included with a median patient age of 15 years; most of them were females (76%, 369/486). Of available pain scores within 2 hours of IV VPA administration, 41% (173/425) had ≥50% pain reduction. Fifty-two percent (254/486) were discharged without additional treatment, 14% (69/486) were discharged after additional treatment, and 33% (163/486) were admitted to the hospital. Initial pain score, number of preceding home treatments, and number of preceding ED treatments were not associated with ED disposition. Oral VPA tapers were prescribed in 39% (94/253) of encounters when the patient was discharged after IV VPA. Oral VPA tapers produced a transient decrease in recurrence at 72 hours, which was no longer present at 1 week nor 1 month. There was no difference in the time to recurrence or total number of return visits within 1 month. Discussion: IV VPA was efficacious in treating pediatric headaches evaluated in the ED, with nearly two-thirds of patients discharged home after administration. Oral VPA tapers did not reduce total headache recurrence nor time to recurrence. Given the limited benefit of oral VPA tapers, this practice should be re-examined. Classification of Evidence: This study provides Class IV evidence that for children with headache seen in the ED, IV VPA reduces head pain and Class III evidence that following this with an oral VPA taper is of no benefit.
RESUMEN
Continuous ketamine infusions have been studied as an adjunctive agent for refractory status epilepticus (RSE) and super refractory status epilepticus (SRSE) in older children and adults. However, minimal information exists on the efficacy, safety, and dosing for continuous ketamine in young infants. We present the clinical course of 3 young infants with RSE and SRSE who received continuous ketamine in conjunction with other antiseizure medications. The condition of these patients was refractory to an average of 6 antiseizure medications before initiation of continuous ketamine infusion. For each patient, a continuous ketamine infusion was initiated at a rate of 1 mg/kg/hr with 1 patient requiring titration to a maximum of 6 mg/kg/hr. In 1 case, the concomitant use of continuous ketamine allowed for a reduction in the benzodiazepine continuous infusion rate. In all cases, ketamine was well tolerated especially in the setting of hemodynamic instability. Ketamine may provide a safe adjunct in the acute setting in severe RSE and SRSE. This is the first case series to document the use of continuous ketamine as a treatment modality in young infants with RSE or SRSE secondary to various underlying etiologies, without adverse events. Further studies are needed to evaluate the long-term safety and efficacy of continuous ketamine in this patient population.
RESUMEN
Background: Communication around serious illness is a core competency for all residencies. One-fifth of neurology residencies have no curriculum. Published curricula use didactics or role-play to assess confidence performing this skill without evaluation in clinical settings. The SPIKES mnemonic (Setting, Perception, Invitation, Knowledge, Empathy, Strategy/Summary) outlines 6 evidence-based steps for communication around serious illness. It is unknown whether child neurology residents can incorporate SPIKES into communication around serious illness in clinical settings. Objective: To develop and evaluate a curriculum on communication around serious illness using SPIKES for child neurology residents that shows long-term skill retention in clinical settings at a single institution. Methods: In 2019, we created a pre-post survey and skills checklist based on SPIKES, with 20 total including 10 core skills. Faculty observed residents' (n = 7) communication with families and completed both preintervention and postintervention checklists for comparison. Residents underwent training in SPIKES during a 2-hour session using didactic and coached role-play. Results: All (n = 7) residents completed preintervention surveys, 4 of 6 completed postintervention. All (n = 6) participated in the training session. Following the training, 75% of residents reported improved confidence in use of SPIKES, though 50% were still unsure about appropriately responding to emotions. There was improvement in all SPIKES skills, with significant improvement in 6 of 20 skills up to 1 year following training. Conclusion: This is the first evaluation of the implementation of a communication around serious illness curriculum for child neurology residents. We identified improved comfort with SPIKES after training. Successful acquisition and utilization of this framework in our program suggests it could be incorporated into any residency program.

PURPOSE: In 2011, the authors conducted a survey regarding continuous EEG (CEEG) utilization in critically ill children. In the interim decade, the literature has expanded, and guidelines and consensus statements have addressed CEEG utilization. Thus, the authors aimed to characterize current practice related to CEEG utilization in critically ill children. METHODS: The authors conducted an online survey of pediatric neurologists from 50 US and 12 Canadian institutions in 2022. RESULTS: The authors assessed responses from 48 of 62 (77%) surveyed institutions. Reported CEEG indications were consistent with consensus statement recommendations and included altered mental status after a seizure or status epilepticus, altered mental status of unknown etiology, or altered mental status with an acute primary neurological condition. Since the prior survey, there was a 3- to 4-fold increase in the number of patients undergoing CEEG per month and greater use of written pathways for ICU CEEG. However, variability in resources and workflow persisted, particularly regarding technologist availability, frequency of CEEG screening, communication approaches, and electrographic seizure management approaches. CONCLUSIONS: Among the surveyed institutions, which included primarily large academic centers, CEEG use in pediatric intensive care units has increased with some practice standardization, but variability in resources and workflow were persistent.
RESUMEN
Critically ill children with acute neurologic dysfunction are at risk for a variety of complications that can be detected by noninvasive bedside neuromonitoring. Continuous electroencephalography (cEEG) is the most widely available and utilized form of neuromonitoring in the pediatric intensive care unit. In this article, we review the role of cEEG and the emerging role of quantitative EEG (qEEG) in this patient population. cEEG has long been established as the gold standard for detecting seizures in critically ill children and assessing treatment response, and its role in background assessment and neuroprognostication after brain injury is also discussed. We explore the emerging utility of both cEEG and qEEG as biomarkers of degree of cerebral dysfunction after specific injuries and their ability to detect both neurologic deterioration and improvement.

BACKGROUND: Continuous electroencephalography (cEEG) is commonly used for neuromonitoring in pediatric intensive care units (PICU); however, there are barriers to real-time interpretation of EEG data. Quantitative EEG (qEEG) transforms the EEG signal into time-compressed graphs, which can be displayed at the bedside. A survey was designed to understand current PICU qEEG use. METHODS: An electronic survey was sent to the Pediatric Neurocritical Care Research Group and Pediatric Status Epilepticus Research Group, and intensivists in 16 Canadian PICUs. Questions addressed demographics, qEEG acquisition and storage, clinical use, and education. RESULTS: Fifty respondents from 39 institutions completed the survey (response rate 53% [39 of 74 institutions]), 76% (37 of 50) from the United States and 24% (12 of 50) from Canada. Over half of the institutions (22 of 39 [56%]) utilize qEEG in their ICUs. qEEG use was associated with having a neurocritical care (NCC) service, ≥200 NCC consults/year, ≥1500 ICU admissions/year, and ≥4 ICU EEGs/day (P < 0.05 for all). Nearly all users (92% [24 of 26]) endorsed that qEEG enhanced care of children with acute neurological injury. Lack of training in qEEG was identified as a common barrier [85% (22 of 26)]. Reviewing and reporting of qEEG was not standard at most institutions. Training was required by 14% (three of 22) of institutions, and 32% (seven of 22) had established curricula. CONCLUSIONS: ICU qEEG was used at more than half of the institutions surveyed, but review, reporting, and application of this tool remained highly variable. Although providers identify qEEG as a useful tool in patient management, further studies are needed to define clinically meaningful pediatric trends, standardize reporting, and enhance educate bedside providers.

Background and Purpose: Long-term outcomes after pediatric neurocritical illness are poorly characterized. This study aims to characterize the frequency and risk factors for post-discharge unplanned health resource use in a pediatric neurocritical care population using insurance claims data. Methods: Retrospective cohort study evaluating children who survived a hospitalization for an acute neurologic illness or injury requiring mechanical ventilation for >72 hours and had insurance eligibility in Colorado's All Payers Claims database. Insurance claims identified unplanned readmissions and emergency department [ED] visits during the post-discharge year. For patients without pre-existing epilepsy/seizures, we evaluated for post-ICU epilepsy identified by claim(s) for a maintenance anti-seizure medication during months 6-12 post-discharge. Multivariable logistic regression identified factors associated with each outcome. Results: 101 children, median age 3.7 years (interquartile range (IQR) .4-11.9), admitted for trauma (57%), hypoxic-ischemic injury (17%) and seizures (15%). During the post-discharge year, 4 (4%) patients died, 26 (26%) were readmitted, and 48 (48%) had an ED visit. Having a pre-existing complex chronic condition was independently associated with readmission and emergency department visit. Admission for trauma was protective against readmission. Of those without pre-existing seizures (n = 86), 25 (29%) developed post-ICU epilepsy. Acute seizures during admission and prolonged ICU stays were independently associated with post-ICU epilepsy. Conclusions: Survivors of pediatric neurocritical illness are at risk of unplanned healthcare use and post-ICU epilepsy. Critical illness risk factors including prolonged ICU stay and acute seizures may identify cohorts for targeted follow up or interventions to prevent unplanned healthcare use and post-ICU epilepsy.
RESUMEN
BACKGROUND AND OBJECTIVES: Inpatient child neurology programs provide essential services for children. We sought to understand the current structure and challenges of inpatient pediatric neurologic care delivery in academic programs in North America. METHODS: We identified a single child neurologist from 39 of the first 40 programs on the 2019-2020 US News and World Report ranking and 3 large Canadian programs to be invited to participate in an inpatient focused survey. In October 2020, these 42 child neurologists were invited to complete an anonymous on-line survey including 37 questions about the structure, workload, and challenges of their inpatient program. Data was analyzed descriptively. RESULTS: We received responses from 30/42 (71%) invited child neurologists from unique programs. The majority (25/30, 83%) were Child Neurology Program Directors, Inpatient Directors, and/or Division Chiefs. Two-thirds (20/30, 67%) reported a total of 2-4 inpatient services. Two-thirds (20/30, 67%) reported a primary neurology admitting service. Nearly two-thirds (19/30, 63%) reported a separate ICU service, and about one-third (11/30, 37%) reported a separate stroke/vascular service. Half of respondents (15/30, 50%) reported some attendings whose primary clinical effort is in the inpatient setting. Over half (17/30, 57%) reported having trainees interested in inpatient-focused careers. About half (16/30, 53%) reported a full-time equivalent metric for inpatient time, and under half (13/30, 43%) reported use of critical-care billing. Most respondents (26/30, 87%) endorsed that inpatient attendings frequently complete documentation/sign notes outside of normal daytime hours. During night call, attendings commonly spend 30 minutes-2 hours on patient care-related phone calls between 5pm-10pm (24/30, 80%) and receive 1-3 patient care-related phone calls after 10pm (21/30, 70%). Faculty burnout was the biggest inpatient-specific challenge before the COVID-19 pandemic (25/30, 83%), and concern about faculty well-being during the COVID-19 pandemic was reported in nearly all respondents (28/30, 93%). DISCUSSION: Academic child neurology programs in North America implement varied models for inpatient care delivery and face common challenges. The information presented in this study serves to stimulate discussion, help optimize operations, and encourage novel approaches to accomplish work and advance careers in academic inpatient child neurology.
RESUMEN
Importance: Families and clinicians have limited validated tools available to assist in estimating long-term outcomes early after pediatric cardiac arrest. Blood-based brain-specific biomarkers may be helpful tools to aid in outcome assessment. Objective: To analyze the association of blood-based brain injury biomarker concentrations with outcomes 1 year after pediatric cardiac arrest. Design, Setting, and Participants: The Personalizing Outcomes After Child Cardiac Arrest multicenter prospective cohort study was conducted in pediatric intensive care units at 14 academic referral centers in the US between May 16, 2017, and August 19, 2020, with the primary investigators blinded to 1-year outcomes. The study included 120 children aged 48 hours to 17 years who were resuscitated after cardiac arrest, had pre-cardiac arrest Pediatric Cerebral Performance Category scores of 1 to 3 points, and were admitted to an intensive care unit after cardiac arrest. Exposure: Cardiac arrest. Main Outcomes and Measures: The primary outcome was an unfavorable outcome (death or survival with a Vineland Adaptive Behavior Scales, third edition, score of <70 points) at 1 year after cardiac arrest. Glial fibrillary acidic protein (GFAP), ubiquitin carboxyl-terminal esterase L1 (UCH-L1), neurofilament light (NfL), and tau concentrations were measured in blood samples from days 1 to 3 after cardiac arrest. Multivariate logistic regression and area under the receiver operating characteristic curve (AUROC) analyses were performed to examine the association of each biomarker with outcomes on days 1 to 3. Results: Among 120 children with primary outcome data available, the median (IQR) age was 1.0 (0-8.5) year; 71 children (59.2%) were male. A total of 5 children (4.2%) were Asian, 19 (15.8%) were Black, 81 (67.5%) were White, and 15 (12.5%) were of unknown race; among 110 children with data on ethnicity, 11 (10.0%) were Hispanic, and 99 (90.0%) were non-Hispanic. Overall, 70 children (58.3%) had a favorable outcome, and 50 children (41.7%) had an unfavorable outcome, including 43 deaths. On days 1 to 3 after cardiac arrest, concentrations of all 4 measured biomarkers were higher in children with an unfavorable vs a favorable outcome at 1 year. After covariate adjustment, NfL concentrations on day 1 (adjusted odds ratio [aOR], 5.91; 95% CI, 1.82-19.19), day 2 (aOR, 11.88; 95% CI, 3.82-36.92), and day 3 (aOR, 10.22; 95% CI, 3.14-33.33); UCH-L1 concentrations on day 2 (aOR, 11.27; 95% CI, 3.00-42.36) and day 3 (aOR, 7.56; 95% CI, 2.11-27.09); GFAP concentrations on day 2 (aOR, 2.31; 95% CI, 1.19-4.48) and day 3 (aOR, 2.19; 95% CI, 1.19-4.03); and tau concentrations on day 1 (aOR, 2.44; 95% CI, 1.14-5.25), day 2 (aOR, 2.28; 95% CI, 1.31-3.97), and day 3 (aOR, 2.04; 95% CI, 1.16-3.57) were associated with an unfavorable outcome. The AUROC models were significantly higher with vs without the addition of NfL on day 2 (AUROC, 0.932 [95% CI, 0.877-0.987] vs 0.871 [95% CI, 0.793-0.949]; P = .02) and day 3 (AUROC, 0.921 [95% CI, 0.857-0.986] vs 0.870 [95% CI, 0.786-0.953]; P = .03). Conclusions and Relevance: In this cohort study, blood-based brain injury biomarkers, especially NfL, were associated with an unfavorable outcome at 1 year after pediatric cardiac arrest. Additional evaluation of the accuracy of the association between biomarkers and neurodevelopmental outcomes beyond 1 year is needed.

BACKGROUND: Use of magnetic resonance imaging (MRI) as a tool to aid in neuroprognostication after cardiac arrest (CA) has been described, yet details of specific indications, timing, and sequences are unknown. We aim to define the current practices in use of brain MRI in prognostication after pediatric CA. METHODS: A survey was distributed to pediatric institutions participating in three international studies. Survey questions related to center demographics, clinical practice patterns of MRI after CA, neuroimaging resources, and details regarding MRI decision support. RESULTS: Response rate was 31% (44 of 143). Thirty-four percent (15 of 44) of centers have a clinical pathway informing the use of MRI after CA. Fifty percent (22 of 44) of respondents reported that an MRI is obtained in nearly all patients with CA, and 32% (14 of 44) obtain an MRI in those who do not return to baseline neurological status. Poor neurological examination was reported as the most common factor (91% [40 of 44]) determining the timing of the MRI. Conventional sequences (T1, T2, fluid-attenuated inversion recovery, and diffusion-weighted imaging/apparent diffusion coefficient) are routinely used at greater than 97% of centers. Use of advanced imaging techniques (magnetic resonance spectroscopy, diffusion tensor imaging, and functional MRI) were reported by less than half of centers. CONCLUSIONS: Conventional brain MRI is a common practice for prognostication after CA. Advanced imaging techniques are used infrequently. The lack of standardized clinical pathways and variability in reported practices support a need for higher-quality evidence regarding the indications, timing, and acquisition protocols of clinical MRI studies.

Background and Objectives: Neuroimaging is often part of the workup for a pediatric patient presenting with a seizure to an emergency department (ED). We aim to evaluate when neuroimaging in the ED for children with a non-first-time seizure, or nonindex seizure (NIS), is associated with an acute change in management (ACM). Methods: This is a retrospective cohort study of all pediatric patients presenting to an ED from 2008 to 2018 with a NIS, excluding repeat febrile seizures, who underwent neuroimaging. Clinical characteristics were extracted from the electronic medical record. The primary outcome was new abnormal neuroimaging resulting in an ACM, defined as admission to the hospital, neurosurgical intervention, or new nonseizure medication administration. Results: We identified 492 encounters. Neuroimaging revealed new findings in 21% of encounters and led to ACMs in 5% of encounters. ACMs included admissions, neurosurgical interventions, and nonseizure medication changes. Factors associated with ACM included new seizure type (odds ratio [OR] 3.3, 95% confidence interval [CI] 1.3-8.0), new focal examination finding (OR 3.0, 95% CI 1.3-7.1), altered mental status (OR 2.9, 95% CI 1.2-7.0), and a history of only provoked seizures (OR 2.8, 95% CI 1.0-7.5). Patients with 2 risk factors had an OR of 6.9 (95% CI 1.8-26.5) for an ACM, and those with 3-4 risk factors had an OR of 45.8 (95% CI 9.8-213.2). The negative predictive value for ACM in a patient with no risk factors was 98.6% (95% CI 95.9-99.5). Discussion: Patients with a NIS who have abnormal neuroimaging associated with an ACM present with unique risk factors. Prospectively validating these factors may allow for a prediction tool for NIS in EDs where reduced exposure to ionizing radiation, sedation, and resource utilization are critically important.
RESUMEN
We herein report a case of Childhood Primary Central Nervous System (CNS) Angiitis. This case consisted of a 14-year-old girl who presented with right-sided weakness, aphasia, and a fever. A Magnetic Resonance Imaging of the brain showed multifocal areas of ischemia. Magnetic Resonance Angiography of the head and neck showed narrowing and irregularities of the left middle cerebral artery and right posterior cerebral artery. Cerebrospinal Fluid studies showed a lymphocytic pleocytosis and brain biopsy revealed leptomeningeal and perivascular inflammation. The epidemiology, presenting symptoms, work-up, pathophysiology, diagnostic criteria, and treatment of Childhood Primary CNS angiitis are discussed. This case serves as a reminder that when pediatric patients present with stroke-like symptoms inflammatory etiologies including Primary CNS Angiitis must be considered and treated appropriately in a time sensitive manner.
RESUMEN
Objective: To describe changes in hospital-based care for children with neurologic diagnoses during the initial 6 weeks following regional Coronavirus 2019 Shelter-in-Place orders. Methods: This retrospective cross-sectional study of 7 US and Canadian pediatric tertiary care institutions included emergency and inpatient encounters with a neurologic primary discharge diagnosis code in the initial 6 weeks of Shelter-in-Place (COVID-SiP), compared to the same period during the prior 3 years (Pre-COVID). Patient demographics, encounter length, and neuroimaging and electroencephalography use were extracted from the medical record. Results: 27,900 encounters over 4 years were included. Compared to Pre-COVID, there was a 54% reduction in encounters during Shelter-in-Place. COVID-SiP patients were younger (median 5 years vs 7 years). The incidence of encounters for migraine fell by 72%, and encounters for acute diagnoses of status epilepticus, infantile spasms, and traumatic brain injury dropped by 53%, 55%, and 56%, respectively. There was an increase in hospital length of stay, relative utilization of intensive care, and diagnostic testing (long-term electroencephalography, brain MRI, and head CT (all P<.01)). Conclusion: During the initial 6 weeks of SiP, there was a significant decrease in neurologic hospital-based encounters. Those admitted required a high level of care. Hospital-based neurologic services are needed to care for acutely ill patients. Precise factors causing these shifts are unknown and raise concern for changes in care seeking of patients with serious neurologic conditions. Impacts of potentially delayed diagnosis or treatment require further investigation.
RESUMEN
OBJECTIVES: Survivors of the PICU face long-term morbidities across health domains. In this study, we detail active PICU follow-up programs (PFUPs) and identify perceptions and barriers about development and maintenance of PFUPs. METHODS: A web link to an adaptive survey was distributed through organizational listservs. Descriptive statistics characterized the sample and details of existing PFUPs. Likert responses regarding benefits and barriers were summarized. RESULTS: One hundred eleven respondents represented 60 institutions located in the United States (n = 55), Canada (n = 3), Australia (n = 1), and the United Kingdom (n = 1). Details for 17 active programs were provided. Five programs included broad PICU populations, while the majority were neurocritical care (53%) focused. Despite strong agreement on the need to assess and treat morbidity across multiple health domains, 29% were physician only programs, and considerable variation existed in services provided by programs across settings. More than 80% of all respondents agreed PFUPs provide direct benefits and are essential to advancing knowledge on long-term PICU outcomes. Respondents identified "lack of support" as the most important barrier, particularly funding for providers and staff, and lack of clinical space, though successful programs overcome this challenge using a variety of funding resources. CONCLUSIONS: Few systematic multidisciplinary PFUPs exist despite strong agreement about importance of this care and direct benefit to patients and families. We recommend stakeholders use our description of successful programs as a framework to develop multidisciplinary models to elevate continuity across inpatient and outpatient settings, improve patient care, and foster collaboration to advance knowledge.

BACKGROUND: Neuromonitoring is the use of continuous measures of brain physiology to detect clinically important events in real-time. Neuromonitoring devices can be invasive or non-invasive and are typically used on patients with acute brain injury or at high risk for brain injury. The goal of this study was to characterize neuromonitoring infrastructure and practices in North American pediatric intensive care units (PICUs). METHODS: An electronic, web-based survey was distributed to 70 North American institutions participating in the Pediatric Neurocritical Care Research Group. Questions related to the clinical use of neuromonitoring devices, integrative multimodality neuromonitoring capabilities, and neuromonitoring infrastructure were included. Survey results were presented using descriptive statistics. RESULTS: The survey was completed by faculty at 74% (52 of 70) of institutions. All 52 institutions measure intracranial pressure and have electroencephalography capability, whereas 87% (45 of 52) use near-infrared spectroscopy and 40% (21/52) use transcranial Doppler. Individual patient monitoring decisions were driven by institutional protocols and collaboration between critical care, neurology, and neurosurgery attendings. Reported device utilization varied by brain injury etiology. Only 15% (eight of 52) of institutions utilized a multimodality neuromonitoring platform to integrate and synchronize data from multiple devices. A database of neuromonitoring patients was maintained at 35% (18 of 52) of institutions. Funding for neuromonitoring programs was variable with contributions from hospitals (19%, 10 of 52), private donations (12%, six of 52), and research funds (12%, six of 52), although 73% (40 of 52) have no dedicated funds. CONCLUSIONS: Neuromonitoring indications, devices, and infrastructure vary by institution in North American pediatric critical care units. Noninvasive modalities were utilized more liberally, although not uniformly, than invasive monitoring. Further studies are needed to standardize the acquisition, interpretation, and reporting of clinical neuromonitoring data, and to determine whether neuromonitoring systems impact neurological outcomes.

OBJECTIVE: Seizures are a common neonatal neurologic emergency. Many centers have developed pathways to optimize management. We evaluated neonatal seizure management pathways at level IV neonatal intensive care units (NICUs) in the United States to highlight areas of consensus and describe aspects of variability. METHODS: We conducted a descriptive analysis of 11 neonatal seizure management pathways from level IV NICUs that specialize in neonatal neurocritical care including guidelines for electroencephalography (EEG) monitoring, antiseizure medication (ASM) choice, timing, and dose. RESULTS: Study center NICUs had a median of 70 beds (interquartile range: 52-96). All sites had 24/7 conventional EEG initiation, monitoring, and review capability. Management pathways uniformly included prompt EEG confirmation of seizures. Most pathways included a provision for intravenous benzodiazepine administration if either EEG or loading of ASM was delayed. Phenobarbital 20 mg/kg IV was the first-line ASM in all pathways. Pathways included either fosphenytoin or levetiracetam as the second-line ASM with variable dosing. Third-line ASMs were most commonly fosphenytoin or levetiracetam, with alternatives including topiramate or lacosamide. All pathways provided escalation to continuous midazolam infusion with variable dosing for seizures refractory to initial medication trials. Three pathways also included lidocaine infusion. Nine pathways discussed ASM discontinuation after resolution of acute symptomatic seizures with variable timing. CONCLUSIONS: Despite a paucity of data from controlled trials regarding optimal neonatal seizure management, there are areas of broad agreement among institutional pathways. Areas of substantial heterogeneity that require further research include optimal second-line ASM, dosage, and timing of ASM discontinuation.
