Lee DA, Sohn G, Park KM, Kim SE. Neuroimaging correlation with EEG in status epilepticus. Seizure 2024; 114:106-110. [PMID: 38118284 DOI: 10.1016/j.seizure.2023.12.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 12/04/2023] [Accepted: 12/12/2023] [Indexed: 12/22/2023] Open
Abstract
PURPOSE This study was to correlate EEG patterns with peri‑ictal perfusion CT abnormality (PCA) or peri‑ictal MR abnormality (PMA) in patients with status epilepticus (SE). METHODS This is a retrospective study done with SE patients from January 2016 to December 2021. We defined the PCA as single or multi-territorial cortical and/or thalamic hyper-perfusion. The PMA was defined as increased signal intensity in multiple brain regions including the cortex and subcortical regions. EEG patterns were categorized into electrographic seizure (ESz)/electroclinical seizure (ECSz), ictal-interictal continuum (IIC), and lateralized periodic discharges (LPDs) per the American Clinical Neurophysiology Society's guideline. We analyzed the association between the patterns of EEG and the presence of PCA or PMA. RESULTS Among 73 patients, 26 % (19/73) showed PCA and 25 % (18/73) demonstrated PMA. The patterns of EEG were as follows; ESz/ECSz in 25 % (18/73), IIC in 34 % (25/73), and LPD in 12 % (9/73). There was a significant correlation between the patterns of EEG and the presence of PMA, but not PCA. 48 % (12/25) had both PMA and PCA whereas 52 % (13/25) showed either PMA (6/25) or PCA (7/25). CONCLUSION Although PCA did not reveal an electro-radiographical correlation, PMA was strongly linked to ESz, ECSz, IIC, and LPD.

Abstract
OBJECTIVE Pediatric status epilepticus is one of the most frequent pediatric emergencies, with high mortality and morbidity. Utilizing electronic health records (EHRs) permits analysis of care approaches and disease outcomes at a lower cost than prospective research. However, reviewing EHR manually is time intensive. We aimed to compare refractory status epilepticus (rSE) cases identified by human EHR review with a natural language processing (NLP)-assisted rSE screen followed by a manual review. METHODS We used the NLP screening tool Document Review Tool (DrT) to generate regular expressions, trained a bag-of-words NLP classifier on EHRs from 2017 to 2019, and then tested our algorithm on data from February to December 2012. We compared results from manual review to NLP-assisted search followed by manual review. RESULTS Our algorithm identified 1528 notes in the test set. After removing notes pertaining to the same event by DrT, the user reviewed a total number of 400 notes to find patients with rSE. Within these 400 notes, we identified 31 rSE cases, including 12 new cases not found in manual review, and 19 of the 20 previously identified cases. The NLP-assisted model found 31 of 32 cases, with a sensitivity of 96.88% (95% CI = 82%-99.84%), whereas manual review identified 20 of 32 cases, with a sensitivity of 62.5% (95% CI = 43.75%-78.34%). SIGNIFICANCE DrT provided a highly sensitive model compared to human review and an increase in patient identification through EHRs. The use of DrT is a suitable application of NLP for identifying patients with a history of recent rSE, which ultimately contributes to the implementation of monitoring techniques and treatments in near real time.

Abstract
Status epilepticus is one of the most common life-threatening neurological emergencies in childhood with the highest incidence in the first 5 years of life and high mortality and morbidity rates. Although it is known that a delayed treatment and a prolonged seizure can cause permanent brain damage, there is evidence that current treatments may be delayed and the medication doses administered are insufficient. Here, we summarize current knowledge on treatment of convulsive status epilepticus in childhood and propose a treatment algorithm. We performed a structured literature search via PubMed and ClinicalTrails.org and identified 35 prospective and retrospective studies on children <18 years comparing two and more treatment options for status epilepticus. The studies were divided into the commonly used treatment phases. As a first-line treatment, benzodiazepines buccal/rectal/intramuscular/intravenous are recommended. For status epilepticus treated with benzodiazepine refractory, no superiority of fosphenytoin, levetirazetam, or phenobarbital was identified. There is limited data on third-line treatments for refractory status epilepticus lasting >30 min. Our proposed treatment algorithm, especially for children with SE, is for in and out-of-hospital onset aids to promote the establishment and distribution of guidelines to address the treatment delay aggressively and to reduce putative permanent neuronal damage. Further studies are needed to evaluate if these algorithms decrease long-term damage and how to treat refractory status epilepticus lasting >30 min.

Abstract
Status epilepticus is one of the most frequent pediatric neurological emergencies. While etiology is often influencing the outcome, more easily modifiable risk factors of outcome include detection of prolonged convulsive seizures and status epilepticus and appropriately dosed and timely applied medication treatment. Unpredictability and delayed or incomplete treatment may at times lead to longer seizures, thereby affecting outcomes. Barriers in the care of acute seizures and status epilepticus include the identification of patients at greatest risk of convulsive status epilepticus, potential stigma, distrust, and uncertainties in acute seizure care, including caregivers, physicians, and patients. Furthermore, unpredictability, detection capability, and identification of acute seizures and status epilepticus, limitations in access to obtaining and maintaining appropriate treatment, and rescue treatment options pose challenges. Additionally, timing and dosing of treatment and related acute management algorithms, potential variations in care due to healthcare and physician culture and preference, and factors related to access, equity, diversity, and inclusion of care. We outline strategies for the identification of patients at risk of acute seizures and status epilepticus, improved status epilepticus detection and prediction, and acute closed-loop treatment and status epilepticus prevention. This paper was presented at the 8th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures held in September 2022.

Abstract
OBJECTIVES Status epilepticus (SE) is associated with significant morbidity and mortality in children. SE in the pediatric intensive care unit (PICU) are not well characterized. The aim of this study is to retrospectively investigate the clinical features and treatment of seizures in children admitted to the PICU of our hospital. METHODS We retrospectively examined the clinical characteristics of patients aged between 1 month and 18 years who were admitted to our hospital with SE or who were diagnosed with SE after hospitalization and were followed up with continuous electroencephalographic monitoring between January 2015 and December 2019. RESULTS A total of 88 patients with SE, 50 (56.8%) boys and 38 (43.2%) girls, were included. The median age was 24 months (interquartile range, 12-80 months). When we evaluate the continuous electroencephalographic monitoring data, 27 (30.7%) were lateralized, 20 (22.7%) were multifocal, 30 (34.1%) were generalized, and 11 (12.5%) were bilateral independent epileptic activity. Seventy nine patients (89.8%) were evaluated as convulsive status epilepticus (CSE) and 9 (10.2%) as nonconvulsive status epilepticus (NCSE). Pediatric Risk of Mortality (PRISM III) score and mortality of patients with NCSE were higher ( P = 0.004 and P = 0.046, respectively). Thirteen eight patients (43.1%) were diagnosed as SE, 38 patients (43.1%) as refractory SE, and 12 patients (13.6%) as super-refractory SE. The overall mortality rate was 10.2%. CONCLUSIONS Status epilepticus is a neurological emergency that causes mortality and morbidity. Electroencephalographic monitoring is important for the recognition of seizures and rapid intervention. No superiority of second-line treatments or combined treatments was demonstrated in patients with SE.

Abstract
OBJECTIVE The aim of this study was to provide seizure etiology, semiology, underlying conditions, and out-of- and in-hospital diagnostics, treatment, and outcome data on children with out-of- or in-hospital-onset status epilepticus (SE) according to the International League Against Epilepsy definition that required admission to the pediatric intensive care unit (PICU) for ≥4 hours. METHODS This prospective national surveillance study on SE in childhood and adolescence was conducted over 2 years (07/2019-06/2021). RESULTS This study examined 481 SE episodes in 481 children with a median age of 43 months (1 month to 17 years 11 months), of which 46.2% were female and 50.7% had a previous seizure history. The most frequent acute SE cause was a prolonged, complicated febrile seizure (20.6%). The most common initial seizure types were generalized seizures (49.9%), focal seizures (18.0%), and unknown types (12.1%); 40.5% of patients suffered from refractory SE and 5.0% from super-refractory SE. The three most common medications administered by nonmedically trained individuals were diazepam, midazolam, and antipyretics. The three most frequent anti-seizure medications (ASMs) administered by the emergency physician were midazolam, diazepam, and propofol. The three most common ASMs used in the clinical setting were midazolam, levetiracetam, and phenobarbital. New ASMs administered included lacosamide, brivaracetam, perampanel, stiripentol, and eslicarbazepine. Status epilepticus terminated in 16.0% in the preclinical setting, 19.1% in the emergency department, and 58.0% in the PICU; the outcome was unknown for 6.9%. The median PICU stay length was 2 (1-121) days. The median modified Rankin scale was 1 (0-5) on admission and 2 (0-6) at discharge. New neurological deficits after SE were observed in 6.2%. The mortality rate was 3.5%. SIGNIFICANCE This study provides current real-world out-of- and in-hospital data on pediatric SE requiring PICU admission. New ASMs are more frequently used in this population. This knowledge may help generate a more standardized approach.

Predictors of abnormal electroencephalogram and neuroimaging in children presenting to the emergency department with new-onset afebrile seizures. BMC Pediatr 2022; 22:619. [PMID: 36303125 PMCID: PMC9609244 DOI: 10.1186/s12887-022-03668-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 09/09/2022] [Accepted: 10/07/2022] [Indexed: 11/26/2022] Open
Abstract
Background Electroencephalogram and neuroimaging in pediatric patients with new-onset afebrile seizures are performed to detect any underlying pathological severe condition that may require emergent neuro-intervention and guide prognosis. This study aims to determine the predictors of abnormal EEG and neuroimaging in children presenting to the emergency department with new-onset afebrile seizures. Methods This single-center cross-sectional study was conducted at a tertiary care hospital in Karachi, Pakistan, from July 01, 2019, to June 30, 2021. All patients aged one month to 18 years who presented with new-onset afebrile seizures were included. Demographic and clinical data were recorded, including age, gender, seizure type, duration of seizure, associated signs and symptoms, and disposition. Multivariable regression analysis was applied to determine the predictors of abnormal EEG and CT scan or MRI findings. Results Out of 201 participants, most patients were in the infantile age group (41.3%), with an equal gender distribution. The most common type of seizure was generalized onset 152 (75.6%). EEG was performed on a total of 126 patients (62.7%) and out of these patients, 67 patients (53.1%) had abnormal findings. In a multivariable analysis, the age group of 5 to 10 years and seizure duration of more than 5 min were significantly associated with higher odds of abnormal EEG findings. In contrast, only the focal onset of seizure was significantly associated with higher odds of abnormal neuroimaging findings. Conclusion The study emphasizes the need for a protocol regarding the performance of EEG and neuroimaging in children presenting to the ED with new-onset afebrile seizures that would aid emergency physicians in the direction of appropriate management, thus ensuring a better quality of patient care and outcomes.

Abstract
Objective:Recent trials provide high-quality evidence for second-line treatment of convulsive status epilepticus (CSE) in children. However, the most effective medications for other seizure emergencies are poorly understood without established treatment algorithms. We investigated children presenting to the emergency department with repetitive or prolonged convulsions who required intravenous long-acting antiseizure medications, to determine the relative importance and treatment responsiveness of status epilepticus and seizure clusters. Methods: Retrospective observational study in the emergency department, Royal Children's Hospital, Melbourne, Australia (annual census 90 000) using hospital electronic medical records data of patients presenting with seizures in 2018. For patients receiving parenteral long-acting antiseizure medications, seizures were categorized as convulsive status epilepticus, nonconvulsive status epilepticus, and seizure clusters. Results: 1468 patients (2% of all visits) presented with seizures to the emergency department in 2018. Long-acting antiseizure medications were administered to 97 (7%) children for the emergency management of seizures. The majority presented with seizure clusters (n = 69; 71%). Only 11 (11%) were in convulsive status epilepticus and 17 (18%) in nonconvulsive status epilepticus. In convulsive status epilepticus, nonconvulsive status epilepticus, and seizure clusters, phenytoin was used in 27%, 53%, and 58% and levetiracetam in 73%, 47%, and 32%, respectively. Conclusions:Convulsive status epilepticus represents a small portion of patients requiring parenteral long-acting antiseizure medications. Seizure clusters accounted for >6 times the number of convulsive status epilepticus, yet evidence and treatment algorithms are lacking.

Abstract
Objective This study was undertaken to evaluate benzodiazepine (BZD) administration patterns before transitioning to non‐BZD antiseizure medication (ASM) in pediatric patients with refractory convulsive status epilepticus (rSE). Methods This retrospective multicenter study in the United States and Canada used prospectively collected observational data from children admitted with rSE between 2011 and 2020. Outcome variables were the number of BZDs given before the first non‐BZD ASM, and the number of BZDs administered after 30 and 45 min from seizure onset and before escalating to non‐BZD ASM. Results We included 293 patients with a median (interquartile range) age of 3.8 (1.3–9.3) years. Thirty‐six percent received more than two BZDs before escalating, and the later the treatment initiation was after seizure onset, the less likely patients were to receive multiple BZD doses before transitioning (incidence rate ratio [IRR] = .998, 95% confidence interval [CI] = .997–.999 per minute, p = .01). Patients received BZDs beyond 30 and 45 min in 57.3% and 44.0% of cases, respectively. Patients with out‐of‐hospital seizure onset were more likely to receive more doses of BZDs beyond 30 min (IRR = 2.43, 95% CI = 1.73–3.46, p < .0001) and beyond 45 min (IRR = 3.75, 95% CI = 2.40–6.03, p < .0001) compared to patients with in‐hospital seizure onset. Intermittent SE was a risk factor for more BZDs administered beyond 45 min compared to continuous SE (IRR = 1.44, 95% CI = 1.01–2.06, p = .04). Forty‐seven percent of patients (n = 94) with out‐of‐hospital onset did not receive treatment before hospital arrival. Among patients with out‐of‐hospital onset who received at least two BZDs before hospital arrival (n = 54), 48.1% received additional BZDs at hospital arrival. Significance Failure to escalate from BZDs to non‐BZD ASMs occurs mainly in out‐of‐hospital rSE onset. Delays in the implementation of medical guidelines may be reduced by initiating treatment before hospital arrival and facilitating a transition to non‐BZD ASMs after two BZD doses during handoffs between prehospital and in‐hospital settings.

An Insight into the Current Understanding of Status Epilepticus: From Concept to Management. Neurol Res Int 2021; 2021:9976754. [PMID: 34336284 PMCID: PMC8292065 DOI: 10.1155/2021/9976754] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 06/11/2021] [Accepted: 06/19/2021] [Indexed: 02/07/2023] Open
Abstract
Status epilepticus (SE), a subset of epilepsy, represents a debilitating neurological disorder often associated with alarming mortality and morbidity numbers. Even though SE is one of the extensively researched topics with conspicuous data available in the literature, a scientific gap exists in understanding the heterogeneous facets of the disorder like occurrence, definition, classification, causes, molecular mechanisms, etc., thereby providing a defined management program. Cognizance of this heterogeneity and scientific limitation with its subsequent correlation to the recent advancements in medical and scientific domains would serve not only in bridging the gap but also in developing holistic and prompt management programs. Keeping this as an objective, an extensive literature survey was performed during this study, and key findings have been shared. The present study provides a semantic and perspective synopsis toward acknowledging the diversified nature of SE and its variants with respect to their definition, classification, etiology, diagnosis, and management.

Indications for Inpatient Magnetoencephalography in Children - An Institution's Experience. Front Hum Neurosci 2021; 15:667777. [PMID: 34149382 PMCID: PMC8213217 DOI: 10.3389/fnhum.2021.667777] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Accepted: 04/14/2021] [Indexed: 11/13/2022] Open
Abstract
Magnetoencephalography (MEG) is recognized as a valuable non-invasive clinical method for localization of the epileptogenic zone and critical functional areas, as part of a pre-surgical evaluation for patients with pharmaco-resistant epilepsy. MEG is also useful in localizing functional areas as part of pre-surgical planning for tumor resection. MEG is usually performed in an outpatient setting, as one part of an evaluation that can include a variety of other testing modalities including 3-Tesla MRI and inpatient video-electroencephalography monitoring. In some clinical circumstances, however, completion of the MEG as an inpatient can provide crucial ictal or interictal localization data during an ongoing inpatient evaluation, in order to expedite medical or surgical planning. Despite well-established clinical indications for performing MEG in general, there are no current reports that discuss indications or considerations for completion of MEG on an inpatient basis. We conducted a retrospective institutional review of all pediatric MEGs performed between January 2012 and December 2020, and identified 34 cases where MEG was completed as an inpatient. We then reviewed all relevant medical records to determine clinical history, all associated diagnostic procedures, and subsequent treatment plans including epilepsy surgery and post-surgical outcomes. In doing so, we were able to identify five indications for completing the MEG on an inpatient basis: (1) super-refractory status epilepticus (SRSE), (2) intractable epilepsy with frequent electroclinical seizures, and/or frequent or repeated episodes of status epilepticus, (3) intractable epilepsy with infrequent epileptiform discharges on EEG or outpatient MEG, or other special circumstances necessitating inpatient monitoring for successful and safe MEG data acquisition, (4) MEG mapping of eloquent cortex or interictal spike localization in the setting of tumor resection or other urgent neurosurgical intervention, and (5) international or long-distance patients, where outpatient MEG is not possible or practical. MEG contributed to surgical decision-making in the majority of our cases (32 of 34). Our clinical experience suggests that MEG should be considered on an inpatient basis in certain clinical circumstances, where MEG data can provide essential information regarding the localization of epileptogenic activity or eloquent cortex, and be used to develop a treatment plan for surgical management of children with complicated or intractable epilepsy.

Abstract
In children, seizures represent an extremely heterogeneous group of medical conditions ranging from benign cases, such as a simple febrile seizure, to life-threatening situations, such as status epilepticus. Underlying causes of seizures also represent a wide range of pathologies from idiopathic cases, usually genetic, to a variety of acute and chronic intracranial or systemic abnormalities. This document discusses appropriate utilization of neuroimaging tests in a child with seizures. The clinical scenarios in this document take into consideration different circumstances at the time of a child's presentation including the patient's age, precipitating event (if any), and clinical and electroencephalogram findings and include neonatal seizures, simple and complex febrile seizures, post-traumatic seizures, focal seizures, primary generalized seizures in a neurologically normal child, and generalized seizures in neurologically abnormal child. This practical approach aims to guide clinicians in clinical decision-making and to help identify efficient and appropriate imaging workup. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
PURPOSE This study aimed to investigate the genetic aetiology in Chinese children diagnosed with status epilepticus (SE). METHODS Next-generation sequencing, copy number variation (CNV) analysis, and other genetic testing methods were conducted for children with SE lacking an identifiable non-genetic aetiology. Furthermore, the phenotype and molecular data of patients with SE were retrospectively analysed. RESULTS Among children with SE lacking an identifiable non-genetic aetiology, 73 out of 163 children (44.8 %) were found to have causative variants associated with SE including 66 monogenic mutations in 22 genes and 7 CNVs. Based on the American College of Medical Genetics and Genomics scoring system, the monogenic variants included 64 pathogenic/likely pathogenic and 2 uncertain significance variants. SCN1A gene mutations (n = 32) were the most common cause, followed by TSC2 (n = 5), CACNA1A (n = 5), SCN2A (n = 4), SCN9A (n = 2) and DEPDC5 (n = 2) gene mutations. Sixteen mutations were identified in single genes. Furthermore, 51 (77.3 %) monogenic mutations were de novo. Age at SE onset < 1 year (odds ratio [OR] = 2.70, 95 % confidence interval [CI]: 1.25-5.83, p = 0.012) and co-morbidity of intellectual disability (OR = 3.36, 95 %CI: 1.61-6.99, p = 0.001) were independently associated with pathogenic genetic variants. CONCLUSION This study identified genetic aetiology in 44.8 % of patients with SE, which indicates a high burden of genetic aetiology among children with SE in China. Our findings highlight the importance for genetic testing of children with SE that lacks an identifiable non-genetic aetiology.

Abstract
OBJECTIVES The purpose of this study was to describe and compare the initial management, including clinical/biological investigation and treatment, of new-onset seizures and status epilepticus (SE) in children versus seizures and SE in those with known epilepsy. METHODS This was a retrospective, single-center, observational study conducted in an urban pediatric hospital in Paris. All patients, aged from 1 month to 18 years, admitted to the pediatric intensive care unit, the high-dependency care unit, and those who required hospitalization in the short-term unit of the emergency department between January 1 and December 31, 2014 for seizures and/or SE were included. RESULTS We analyzed the data of 190 children: new-onset seizures (N=118; group A) versus those with known epilepsy (N=72; group B). At least one diagnostic test was performed on 156 patients (82.1%) (group A, N=104, 88.1%; group B, N=52, 72.2%; P=0.05). In group B, blood levels of antiepileptic drugs were measured in 14 of the 38 patients with SE, of whom six were under dosed. Treatments were: first line, diazepam (group A, 80%; group B, 46%; P<0.001); second line, diazepam (group A, 56%; group B, 34%; P=0.02) or clonazepam (group A, 24%; group B, 46%; P=0.001); third line, phenytoin (group A, 54%; group B, 22%; P<0.001) or clonazepam (group A, 18%; group B, 61%; P<0.001). CONCLUSION Diagnostic evaluation and treatment should be individualized for children with known epilepsy.

Abstract
PURPOSE To evaluate whether the onset of pediatric refractory status epilepticus (rSE) is related to time of day. METHOD We analyzed the time of day for the onset of rSE in this prospective observational study performed from June 2011 to May 2019 in pediatric patients (1 month to 21 years of age). We evaluated the temporal distribution of pediatric rSE utilizing a cosinor analysis. We calculated the midline estimating statistic of rhythm (MESOR) and amplitude. MESOR is the estimated mean number of rSE episodes per hour if they were evenly distributed. Amplitude is the difference between MESOR and maximum rSE episodes/hour, or between MESOR and minimum rSE episodes/hour. We also evaluated the temporal distribution of time to treatment. RESULTS We analyzed 368 patients (58% males) with a median (p25 - p75) age of 4.2 (1.3-9.7) years. The MESOR was 15.3 (95% CI: 13.9-16.8) and the amplitude was 3.2 (95% CI: 1.1-5.3), p = 0.0024, demonstrating that the distribution is not uniform, but better described as varying throughout the day with a peak in the morning (11am-12 pm) and trough at night (11 pm-12 am). The duration from rSE onset to application of the first non-benzodiazepine antiseizure medication peaked during the early morning (2am-3 am) with a minimum during the afternoon (2 pm-3 pm) (p = 0.0179). CONCLUSIONS The distribution of rSE onset is not uniform during the day. rSE onset shows a 24-h distribution with a peak in the mid-morning (11am-12 pm) and a trough at night (11 pm-12am).

Abstract
Introduction The objective of this study was to describe the course and the outcomes of children with convulsive status epilepticus and to evaluate the differences between two groups of children with new-onset seizures and known seizure disorders. Methods This is a retrospective, single-center study. Children with convulsive status epilepticus admitted to our tertiary care pediatric intensive care unit were included in the study. Medical records were reviewed to obtain the demographic- and seizure-related variables. Results Among 139 children with status epilepticus, 69.7% (n = 99) had a known seizure disorder. Focal seizures were present in 23.9% of children, and 34.6% required intubation; there was an overall mortality rate of 1.2%. The children with new-onset seizures were younger and received electroencephalography (EEG) and neuroimaging more often compared to children with known seizure disorders (p < 0.05). However, an abnormal EEG was more common among children with known seizure disorders (p < 0.001). Conclusions Sub-therapeutic anti-epileptic drugs levels were common among children with known seizure disorders presenting with status epilepticus. Gender, race, insurance status, type of seizures, intubation requirement, lengths of stay, and mortality were not significantly different between the two groups.

Abstract
We reviewed 37 studies reporting long-term outcomes after a status epilepticus (SE) episode in pediatric and adult populations. Study design, length of follow-up, outcome measures, domains investigated (mortality, SE recurrence, subsequent epilepsy, cognitive outcome, functional outcome, or quality of life), and predictors of long-term outcomes are summarized. Despite heterogeneity in the design of prior studies, overall risk of poor long-term outcome after SE is high in both children and adults. Etiology is the main determinant of outcome, and the effect of age or SE duration is often difficult to distinguish from the underlying cause. The effect of the treatment on long-term outcome after SE is still unknown.

Abstract
BACKGROUND Many pediatric patients presenting with status epilepticus have no history of seizures. METHODS We retrospectively analyzed the clinical characteristics of patients aged one month to 21 years who presented during six consecutive years with convulsive status epilepticus and without a history of seizures. New-onset refractory status epilepticus was defined as status epilepticus refractory to two lines of treatment, without an identified cause in the first 48 hours. RESULTS Of 460 patients with status epilepticus, 79 (17.2%) presented with new-onset status epilepticus, including four (0.9%) with new-onset refractory status epilepticus. Of those patients, 54.4% were female, and the median age was 3.5 years (IQR: 1.08 to 6.75). The median seizure duration was 20 minutes (IQR: 10 to 40 minutes). Etiology was unknown in 36.7%, symptomatic in 30.3%, provoked in 16.5%, and provoked with an existing symptomatic etiology in 16.5%. Patients were followed for a median duration of 63 months (IQR: 21 to 97). The mortality rate was 3.8%. Of 55 patients who were developmentally normal at baseline, 29.1% had a significant cognitive impairment at the last follow-up, and 20% had academic difficulties or behavioral problems. Patients with symptomatic etiology had greater odds of having cognitive and behavioral problems compared with patients with unknown etiology (odds ratio = 3.83, P = 0.012). CONCLUSIONS Patients with new-onset status epilepticus are at risk for recurrent seizures, recurrent status epilepticus, death, and subsequent cognitive-behavioral impairment. Specific monitoring and care interventions might be required in this high-risk population.

Abstract
Limited data exist for health care providers regarding seizure recurrence after a first unprovoked seizure in previously neurologically and developmentally normal children. A systematic review and meta-analysis was conducted to assess seizure recurrence after a first unprovoked seizure by performing an electronic search in PubMed, Embase, and Scopus. Six studies from 2817 met the inclusion criteria. The sample size consisted of 815 neurologically and developmentally normal children (1 month-17.5 years) on no antiepileptic drugs. This systematic review and meta-analysis estimated a recurrence rate within 3 years of 45% (95% CI: 37%, 60%). This estimate provides a touchstone for health care providers who are managing this particular population of children.

Abstract
PURPOSE Convulsive status epilepticus (CSE) is associated with a high morbidity and mortality. This study aimed to describe the clinical profile, aetiology, neuroimaging and EEG findings as well as outcome of children with CSE in Sub-Saharan Africa. METHODS This was a retrospective analysis of electronic records of children with CSE admitted to the Paediatric Intensive Care Unit (PICU) over an 8-year period from January 2007 to December 2014. RESULTS Seventy six patients were admitted to the PICU with CSE and 55(72%) had refractory status epilepticus. The median age at presentation was 15 months (IQR 6-37 months). The main aetiologies were meningoencephalitis and gastroenteritis in 33(43%) and 19(25%) patients respectively. The most frequently used antiepileptic drugs for CSE in PICU consisted of infusions of midazolam (96%) and thiopentone (22%). Neuroimaging findings were abnormal in 53(75%) patients with hypoxic changes in 17 patients. On multivariable regression, the predictors of poor outcome included the use of more than 3 antiepileptic drugs in PICU(RR-1.41(1.12-1.78), p=0.003), duration of mechanical ventilation for more than 3days (RR 1.98(1.22-3.20), p=0.005) and abnormal neuroimaging findings (RR 3.21(1.53-6.72), p=0.002). The mortality rate was 24%(n=18). Persistent seizures or a new neurological deficit occurred in 58%(n=44). The main cause of mortality was CSE related diffuse cortical and brainstem injury. Predominant neurological sequelae were cerebral palsy and persistent epilepsy. CONCLUSION The high burden of infection related CSE is associated with high morbidity and mortality rates in contrast to the rates in developed countries. This highlights the need for early recognition and treatment of underlying conditions.

Abstract
OBJECTIVES Because meningitis may trigger seizures, we sought to determine its frequency in children with first-time status epilepticus (SE). METHODS We performed a retrospective cross-sectional study of children aged 1 month to 21 years who presented to a single pediatric emergency department between 1995 and 2012 with SE and who had a lumbar puncture (LP) performed as part of the diagnostic evaluation. We defined bacterial meningitis as a cerebrospinal fluid (CSF) culture positive for a bacterial pathogen or CSF pleocytosis (CSF white blood cells ≥10 cells/mm) with a blood culture positive for a bacterial pathogen. We defined viral meningitis or encephalitis using a positive enterovirus or herpes simplex virus polymerase chain reaction test. RESULTS Among 126 children with SE who had an LP performed, 8 (6%) had CSF pleocytosis. Of these, 5 had received antibiotics before performance of a diagnostic LP. One child in the cohort was proven to have bacterial meningitis (0.8%; 95% confidence interval [CI], 0%-6%). Two other children had enteroviral meningitis (2/13 tested, 15%; 95% CI, 3%-51%), and 1 had a herpes simplex virus infection (1/47, 2%; 95% CI, 0%-15%). CONCLUSIONS Bacterial meningitis is an uncommon cause of SE.

Abstract
Paediatric status epilepticus (SE) is a medical emergency and a common critical condition confronting pre-hospital providers. Management in the pre-hospital environment is challenging but considered extremely important as a potentially modifiable factor on outcome. Recent data from multicentre clinical trials, quality observational studies and consensus documents have influenced management in this area, and is important to both pre-hospital providers and emergency physicians. The objective of this review was to: (i) present an overview of the available evidence relevant to pre-hospital care of paediatric SE; and (ii) assess the current pre-hospital practice guidelines in Australia and New Zealand. The review outlines current definitions and guidelines of SE management, regional variability in pre-hospital protocols within Australasia and aspects of pre-hospital care that could potentially be improved. Contemporary data is required to determine current practice in our setting. It is important that paediatric neurologists, emergency physicians and pre-hospital care providers are all engaged in future endeavours to improve clinical care and knowledge translation efforts for this patient group.

Abstract
BACKGROUND The aim of this study was to explore the effect and possible mechanism of sodium valproate (VPA) on the cognitive function and the hippocampus of rats after convulsive status epilepticus (CES). MATERIAL AND METHODS A rat model of CES was established and the Morris water maze was used to observe changes in the cognitive function of the rats after the administration of VPA. Acute hippocampal slices were made to detect field excitatory postsynaptic potential. Western blot analysis was used to test for the expression of CaMKII and p-CaMKII. RESULTS (1) CSE caused no spatial reference memory (SFM) or spatial working memory (SWM) damage to 15-day-old (P15) rats, but caused significant SRM and SWM damage to 35-day-old (P35) rats. VPA damaged the SRM and SWM of P15 rats in both the CSE and control groups. However, VPA improved the memory damage caused by CSE in P35 rats. (2) VPA treatment in vivo increased the induced success rate and the sustainable time of long-term potentiation (LTP) in P35 rats, and also inhibited the expression of CaMKII and p-CaMKII in both P15 and P35 rats. CONCLUSIONS VPA significantly improved spatial cognitive dysfunction in a CSE model of P35 rats, and damaged the spatial memory of normal P15 and P35 rats. Improvements after administration of VPA were closely related to the increase of induced success rate and the prolongation of the sustainable time of LTP. VPA treatment in vivo, which inhibited expression and phosphorylation of CaMKII, showed no obvious inhibition on LTP, which may be related to the elution effect of VPA.

Abstract
We aimed to evaluate the determinants of outcome in new onset refractory status epilepticus (SE). A retrospective analysis of patients with new onset SE admitted between May 2005 and October 2013 was performed. Regression analysis was used to determine factors that affect progression of new onset SE to refractory status epilepticus (RSE) and mortality. Among 114 patients with new onset SE, 52 patients progressed to RSE. Sixty seven (58.7%) were men. New onset RSE patients were younger than new onset SE patients (mean 35.9 ± standard deviation18.2 versus 28.7 ± 20.2 years; p=0.050). Cryptogenic aetiology was the most significant determinant of progression of new onset SE to RSE (Exp [β]=5.68; p=0.001). The overall mortality in the entire group was 23.7%, significantly higher in new onset RSE group (40.4% versus 9.7%; p<0.0001). New onset RSE patients with symptomatic and cryptogenic etiology did not differ for clinical characteristics and outcome. Acidosis was the strongest predictor of mortality in the entire cohort (Exp [β]=8.72; p=0.005). Nearly half of the patients with new onset SE progressed to RSE. While cryptogenic aetiology determined progression of new onset SE to RSE, acidosis was associated with mortality. The outcome was similar between symptomatic and cryptogenic new onset RSE.

Abstract
PURPOSE To determine the yield of emergent neuroimaging among children with new-onset seizures presenting with status epilepticus. METHOD We performed a cross-sectional study of children seen at a single ED between 1995 and 2012 with new-onset seizure presenting with status epilepticus. We defined status epilepticus as a single seizure or multiple seizures without regaining consciousness lasting 30 min or longer. Our primary outcome was urgent or emergent intracranial pathology identified on neuroimaging. We categorized neuroimaging results as emergent if they would have changed acute management as assessed by a blinded neuroradiologist and neurologist. To ensure abnormalities were not missed, we review neuroimaging results for 30 days following the initial episode of SE. RESULTS We included 177 children presenting with new-onset seizure with status epilepticus, of whom 170 (96%) had neuroimaging performed. Abnormal findings were identified on neuroimaging in 64/177 (36%, 95% confidence interval 29-43%) children with 15 (8.5%, 95% confidence interval 5.2-14%) children having urgent or emergent pathology. Four (27%) of the 15 children with urgent or emergent findings had a normal non-contrast computed tomography scan and a subsequently abnormal magnetic resonance image. Longer seizure duration and older age were associated with urgent or emergent intracranial pathology. CONCLUSION A substantial minority of children with new-onset seizures presenting with status epilepticus have urgent or emergent intracranial pathology identified on neuroimaging. Clinicians should strongly consider emergent neuroimaging in these children. Magnetic resonance imaging is the preferred imaging modality when available and safe.

Abstract
Convulsive status epilepticus is a common neurologic emergency in pediatrics. We aimed to study the etiology, clinical features, and prognostic factors among pediatric patients with convulsive status epilepticus. Seventy patients were included in this cohort study from pediatric emergency department of the specialized Children Hospital of Cairo University. The outcome was evaluated using the Glasgow Outcome Score. Acute symptomatic etiology was the most common cause of convulsive status epilepticus. Refractory convulsive status epilepticus was observed more significantly in cases caused by acute symptomatic etiologies. The outcome was mortality in 26 (37.1%) patients, severe disability in 15 (21.4%), moderate disability in 17 (24.3%), and good recovery in 12 (17.1%) patients. The significant predictor of mortality was lower modified Glasgow Coma Scale score on admission, whereas lower modified Glasgow Coma Scale score on admission and refractory convulsive status epilepticus were the significant predictors for disability and mortality.

Abstract
OBJECTIVE To describe the time elapsed from onset of pediatric convulsive status epilepticus (SE) to administration of antiepileptic drug (AED). METHODS This was a prospective observational cohort study performed from June 2011 to June 2013. Pediatric patients (1 month-21 years) with convulsive SE were enrolled. In order to study timing of AED administration during all stages of SE, we restricted our study population to patients who failed 2 or more AED classes or needed continuous infusions to terminate convulsive SE. RESULTS We enrolled 81 patients (44 male) with a median age of 3.6 years. The first, second, and third AED doses were administered at a median (p25-p75) time of 28 (6-67) minutes, 40 (20-85) minutes, and 59 (30-120) minutes after SE onset. Considering AED classes, the initial AED was a benzodiazepine in 78 (96.3%) patients and 2 (2-3) doses of benzodiazepines were administered before switching to nonbenzodiazepine AEDs. The first and second doses of nonbenzodiazepine AEDs were administered at 69 (40-120) minutes and 120 (75-296) minutes. In the 64 patients with out-of-hospital SE onset, 40 (62.5%) patients did not receive any AED before hospital arrival. In the hospital setting, the first and second in-hospital AED doses were given at 8 (5-15) minutes and 16 (10-40) minutes after SE onset (for patients with in-hospital SE onset) or after hospital arrival (for patients with out-of-hospital SE onset). CONCLUSIONS The time elapsed from SE onset to AED administration and escalation from one class of AED to another is delayed, both in the prehospital and in-hospital settings.

Abstract
INTRODUCTION Convulsive status epilepticus (SE) is one of the most frequent and severe neurological emergencies in both adults and children. A timely administration of appropriate antiepileptic drugs (AEDs) can stop seizures early and markedly improve outcome. AREAS COVERED The main treatment strategies for SE are reviewed with an emphasis on initial treatments. The established first-line treatment consists of benzodiazepines, most frequently intravenous lorazepam. Benzodiazepines that do not require intravenous administration like intranasal midazolam or intramuscular midazolam are becoming more popular because of easier administration in the field. Other benzodiazepines may also be effective. After treatment with benzodiazepines, treatment with fosphenytoin and phenobarbital is usually recommended. Other intravenously available AEDs, such as valproate and levetiracetam, may be as effective and safe as fosphenytoin and phenobarbital, have a faster infusion time and better pharmacokinetic profile. The rationale behind the need for an early treatment of SE is discussed. The real-time delays of AED administration in clinical practice are described. EXPERT OPINION There is limited evidence to support what the best initial benzodiazepine or the best non-benzodiazepine AED is. Recent and developing multicenter trials are evaluating the best treatment options and will likely modify the recommended treatment choices in SE in the near future. Additionally, more research is needed to understand how different treatment options modify prognosis in SE. Timely implementation of care protocols to minimize treatment delays is crucial.

Abstract
PURPOSE OF REVIEW Status epilepticus is an acute neurologic emergency, the incidence of which is increasing in the United States as the definition evolves and our detection abilities improve. We will present the current definition of status epilepticus, including a recently modified operational definition for use in the clinical setting. We will also provide updates on identifying children in status epilepticus, etiologic considerations, and the rationale for diagnostic testing. RECENT FINDINGS Recent data reveal the benefits of MRI vs. computed tomography in new-onset status epilepticus, as well as high rates of identification of electrographic seizures in patients with unexplained acute encephalopathy in pediatric ICU settings. Genetic testing should be considered in young children with recurrent status epilepticus. SUMMARY Prompt recognition and diagnostic evaluation of the child in status epilepticus will help identify causes, which may require specific treatment, and help in the management of this life-threatening condition. Laboratory work, neuroimaging, electroencephalogram or continuous video electroencephalogram, lumbar puncture, and genetic testing may be considered in the evaluation of the child in status epilepticus.

Abstract
Status epilepticus (SE) describes persistent or recurring seizures without a return to baseline mental status and is a common neurologic emergency. SE can occur in the context of epilepsy or may be symptomatic of a wide range of underlying etiologies. The clinician's aim is to rapidly institute care that simultaneously stabilizes the patient medically, identifies and manages any precipitant conditions, and terminates seizures. Seizure management involves "emergent" treatment with benzodiazepines followed by "urgent" therapy with other antiseizure medications. If seizures persist, then refractory SE is diagnosed and management options include additional antiseizure medications or infusions of midazolam or pentobarbital. This article reviews the management of pediatric SE and refractory SE.

Abstract
PURPOSE OF REVIEW This review discusses the management of status epilepticus in children, including both anticonvulsant medications and overall management approaches. RECENT FINDINGS Rapid management of status epilepticus is associated with a greater likelihood of seizure termination and better outcomes, yet data indicate that there are often management delays. This review discusses an overall management approach aiming to simultaneously identify and manage underlying precipitant causes, administer anticonvulsants in rapid succession until seizures have terminated, and identify and manage systemic complications. An example management pathway is provided. SUMMARY Status epilepticus is a common neurologic emergency in children and requires rapid intervention. Having a predetermined status epilepticus management pathway can expedite management.

Midazolam fails to prevent neurological damage in children with convulsive refractory febrile status epilepticus. Pediatr Neurol 2014; 51:78-84.

Abstract
BACKGROUND We conducted a retrospective study to compare the outcome of intravenous midazolam infusion without electroencephalography or targeted temperature management and barbiturate coma therapy with electroencephalography and targeted temperature management for treating convulsive refractory febrile status epilepticus. PATIENTS Of 49 consecutive convulsive refractory febrile status epilepticus patients admitted to the pediatric intensive care unit of our hospital, 29 were excluded because they received other treatments or because of various underlying illnesses. Thus, eight patients were treated with midazolam and 10 with barbiturate coma therapy using thiamylal. Midazolam-treated patients were intubated only when necessary, whereas barbiturate coma therapy patients were routinely intubated. Continuous electroencephalography monitoring was utilized only for the barbiturate coma group. The titration goal for anesthesia was clinical termination of status epilepticus in the midazolam group and suppression or burst-suppression patterns on electroencephalography in the barbiturate coma group. Normothermia was maintained using blankets and neuromuscular blockade in the barbiturate coma group and using antipyretics in the midazolam group. Prognoses were measured at 1 month after onset; children were classified into poor and good outcome groups. RESULTS Good outcome was achieved in all the barbiturate coma group patients and 50% of the midazolam group patients (P = 0.02, Fisher's exact test). CONCLUSIONS Although the sample size was small and our study could not determine which protocol element is essential for the neurological outcome, the findings suggest that clinical seizure control using midazolam without continuous electroencephalography monitoring or targeted temperature management is insufficient in preventing neurological damage in children with convulsive refractory febrile status epilepticus.

Abstract
OPINION STATEMENT Status epilepticus (SE) is a medical emergency consisting of persistent or recurring seizures without a return to baseline mental status. SE can be divided into subtypes based on seizure types and underlying etiologies. Management should be implemented rapidly and based on pre-determined care pathways. The aim is to terminate seizures while simultaneously identifying and managing precipitant conditions. Seizure management involves "emergent" treatment with benzodiazepines (lorazepam intravenously, midazolam intramuscularly, or diazepam rectally) followed by "urgent" therapy (phenytoin/fosphenytoin, phenobarbital, levetiracetam or valproate sodium). If seizures persist, "refractory" treatments include infusions of midazolam or pentobarbital. Prognosis is dependent on the underlying etiology and seizure persistence. This article reviews the current management strategies for pediatric convulsive SE.

Abstract
PURPOSE Status epilepticus (SE) is a life-threatening condition that can be refractory to initial treatment. Randomized controlled studies to guide treatment choices, especially beyond first-line drugs, are not available. This report summarizes the evidence that guides the management of refractory convulsive SE (RCSE) in children, defines gaps in our clinical knowledge and describes the development and works of the 'pediatric Status Epilepticus Research Group' (pSERG). METHODS A literature review was performed to evaluate current gaps in the pediatric SE and RCSE literature. In person and online meetings helped to develop and expand the pSERG network. RESULTS The care of pediatric RCSE is largely based on extrapolations of limited evidence derived from adult literature and supplemented with case reports and case series in children. No comparative effectiveness trials have been performed in the pediatric population. Gaps in knowledge include risk factors for SE, biomarkers of SE and RCSE, second- and third-line treatment options, and long-term outcome. CONCLUSION The care of children with RCSE is based on limited evidence. In order to address these knowledge gaps, the multicenter pSERG was established to facilitate prospective collection, analysis, and sharing of de-identified data and biological specimens from children with RCSE. These data will allow identification of treatment strategies associated with better outcomes and delineate evidence-based interventions to improve the care of children with SE.

Abstract
Seizures are a commonly encountered condition within the emergency department and, because of this, can engender complacency on the part of the physicians and staff. Unfortunately, there is significant associated morbidity and mortality with seizures, and they should never be regarded as routine. This point is particularly important with respect to seizures in pediatric patients. The aim of this review is to provide a current view of the various issues that make pediatric seizures unique and to help elucidate emergent evaluation and management strategies.

Abstract
Status epilepticus (SE) remains a life-threatening condition that afflicts both adults and children, and may occur at onset of epilepsy, especially in children. Febrile SE is the most common cause in children, while other symptomatic causes are less frequent compared to adults. The aetiological workup that must be undertaken in all cases includes neuroimaging and electroencephalography. The various electroencephalographic patterns seen in patients with SE along with the out-of-hospital treatment for SE in children and treatment strategies in cases that are refractory to first-line medical treatments are discussed. Medically induced coma may be necessary in refractory cases, although the optimal agents to use and degree of electroencephalographic suppression in children remain unclear. Neurosurgery is not a well-known treatment option that could be considered for refractory cases. Although the prognosis has probably improved over the years, it remains a potential life-threatening emergency.

Low-intensity physical training recovers object recognition memory impairment in rats after early-life induced Status epilepticus. Int J Dev Neurosci 2013; 31:196-201.

Abstract
When it occurs early in life, Status epilepticus (SE) can cause behavioural and cognitive impairments in adulthood. Here, we evaluated the putative benefits of low-intensity treadmill training on long-standing cognitive impairment in rats submitted to SE early in life. Wistar rats were submitted to LiCl-pilocarpine-induced SE at P16. Animals from the trained group underwent a low-intensity treadmill protocol for 5 days per week for 4 weeks. At adulthood, rats subjected to early-life SE displayed impairment in long-term memory in an object recognition task, while the training protocol completely reversed this deficit. This result was associated with neither locomotor alterations nor changes in emotional behaviour; there were no differences between groups in the distance travelled, grooming or rearing in the open field test; there were also no differences between groups in the number of risk assessment, time spent in open arms in an elevated plus maze and number of entries into the open arms. These data suggest that physical exercise can ameliorate the long-standing recognition memory deficit induced by early-life SE, suggesting that it may be useful as a putative intervention for patients who suffered SE during infancy.
