Abstract
INTRODUCTION Refractory status epilepticus (RSE) is a diagnosis that can be made when tonic-clonic status epilepticus (SE) and focal SE cannot be stopped by at least two anti-seizure medications after 30 and 60 minutes, respectively, from the time of commencement. It could result in mortality, loss of functionality, neurological deficiency, and other serious short- and long-term effects. AREAS COVERED This narrative review covers original clinical studies of any design and case series investigating long-term outcomes of RSE recorded after at least a year from the SE onset. EXPERT OPINION The future of a patient with RSE rests mostly on the long-term effects of this severe pathological condition, which may be accompanied with systemic complications like hyperthermia, hyperkalemia, acidosis, and/or stress cardiomyopathy. Younger patients with less severe RSE of shorter duration, particularly of the convulsive kind, are reported to have better long-term outcomes. Previous studies on the factors influencing the long-term outcomes of RSE, however, did not link the outcomes to treatment options for the condition. Such circumstances currently prevent making any definitive recommendations on the treatment of RSE until future research with adequate statistical power is completed.

Abstract
Abstract
Background
Pediatric status epilepticus is a neurological emergency with the potential for severe developmental and neurological consequences. Prompt diagnosis and management are necessary.
Objectives
To outline the existing best available evidence for managing pediatric and neonatal status epilepticus, in the light of emerging randomized controlled studies. We also focus on short and long-term prognoses.
Materials and methods
This is a systematic overview of the existing literature.
Results
Status epilepticus, its treatment, and prognosis are usually based on the continuation of seizure activity at 5 and 30 min. Refractory and super-refractory status epilepticus further complicates management and requires continuous EEG monitoring with regular reassessment and adjustment of therapy. Benzodiazepines have been accepted as the first line of treatment on the basis of reasonable evidence. Emerging randomized controlled trials demonstrate equal efficacy for parenterally administered phenytoin, levetiracetam, and valproic acid as second-line agents. Beyond this, the evidence for third-line options is sparse. However, encouraging evidence for midazolam and ketamine exists with further data required for immunological, dietary, and surgical interventions.
Conclusion
Our overview of the management of pediatric and neonatal status epilepticus based on available evidence emphasizes the need for evidence-based guidelines to manage status epilepticus that fails to respond to second-line treatment.

Abstract
NORSE (new onset refractory status epilepticus) has recently been defined as a clinical presentation, not a specific diagnosis, in a patient without active epilepsy or other preexisting relevant neurological disorder, with new onset of refractory status epilepticus without a clear acute or active structural, toxic or metabolic cause. It includes the concept of FIRES described in children with a similar condition but preceded by a 2-14-day febrile illness. NORSE constitutes the acute phase of an entity preceded by a prodromal phase which may be accompanied by numerous manifestations (febrile episode, behavioural changes, headache, …), and followed by a chronic phase marked by long-term neurological sequelae, cognitive impairment, epilepsy and functional disability. There are many causes of NORSE: autoimmune, infectious, genetic, toxic, … but in half of the cases, despite an exhaustive assessment, the cause remains undetermined. Paraneoplastic and non-paraneoplastic autoimmune encephalitis remains by far the leading cause of NORSE. For these reasons, immunotherapy should be considered rapidly in parallel with the treatment of the status epilepticus, including in cryptogenic NORSE. Good communication with the family is important because the management of the acute phase is long and difficult. Although mortality remains high (11-22%), and sequelae can be severe, the majority of survivors can have a good or fair outcome.

Abstract
OBJECTIVES To characterize the pediatric super-refractory status epilepticus population by describing treatment variability in super-refractory status epilepticus patients and comparing relevant clinical characteristics, including outcomes, between super-refractory status epilepticus, and nonsuper-refractory status epilepticus patients. DESIGN Retrospective cohort study with prospectively collected data between June 2011 and January 2019. SETTING Seventeen academic hospitals in the United States. PATIENTS We included patients 1 month to 21 years old presenting with convulsive refractory status epilepticus. We defined super-refractory status epilepticus as continuous or intermittent seizures lasting greater than or equal to 24 hours following initiation of continuous infusion and divided the cohort into super-refractory status epilepticus and nonsuper-refractory status epilepticus groups. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We identified 281 patients (157 males) with a median age of 4.1 years (1.3-9.5 yr), including 31 super-refractory status epilepticus patients. Compared with nonsuper-refractory status epilepticus group, super-refractory status epilepticus patients had delayed initiation of first nonbenzodiazepine-antiseizure medication (149 min [55-491.5 min] vs 62 min [33.3-120.8 min]; p = 0.030) and of continuous infusion (495 min [177.5-1,255 min] vs 150 min [90-318.5 min]; p = 0.003); prolonged seizure duration (120 hr [58-368 hr] vs 3 hr [1.4-5.9 hr]; p < 0.001) and length of ICU stay (17 d [9.5-40 d] vs [1.8-8.8 d]; p < 0.001); more medical complications (18/31 [58.1%] vs 55/250 [22.2%] patients; p < 0.001); lower return to baseline function (7/31 [22.6%] vs 182/250 [73.4%] patients; p < 0.001); and higher mortality (4/31 [12.9%] vs 5/250 [2%]; p = 0.010). Within the super-refractory status epilepticus group, status epilepticus resolution was attained with a single continuous infusion in 15 of 31 patients (48.4%), two in 10 of 31 (32.3%), and three or more in six of 31 (19.4%). Most super-refractory status epilepticus patients (30/31, 96.8%) received midazolam as first choice. About 17 of 31 patients (54.8%) received additional treatments. CONCLUSIONS Super-refractory status epilepticus patients had delayed initiation of nonbenzodiazepine antiseizure medication treatment, higher number of medical complications and mortality, and lower return to neurologic baseline than nonsuper-refractory status epilepticus patients, although these associations were not adjusted for potential confounders. Treatment approaches following the first continuous infusion were heterogeneous, reflecting limited information to guide clinical decision-making in super-refractory status epilepticus.

Abstract
Super-refractory status epilepticus (SRSE) is a life-threatening neurological emergency with high morbidity and mortality. It is defined as “status epilepticus (SE) that continues or recurs 24 hours or more after the onset of anesthesia, including those cases in which SE recurs on the reduction or withdrawal of anesthesia.” This condition is resistant to normal protocols used in the treatment of status epilepticus and exposes patients to increased risks of neuronal death, neuronal injury, and disruption of neuronal networks if not treated in a timely manner. It is mainly seen in patients with severe acute onset brain injury or presentation of new-onset refractory status epilepticus (NORSE). The mortality, neurological deficits, and functional impairments are significant depending on the duration of status epilepticus and the resultant brain damage. Research is underway to find the cure for this devastating neurological condition. In this review, we will discuss the wide range of therapies used in the management of SRSE, provide suggestions regarding its treatment, and comment on future directions. The therapies evaluated include traditional and alternative anesthetic agents with antiepileptic agents. The other emerging therapies include hypothermia, steroids, immunosuppressive agents, electrical and magnetic stimulation therapies, emergent respective epilepsy surgery, the ketogenic diet, pyridoxine infusion, cerebrospinal fluid drainage, and magnesium infusion. To date, there is a lack of robust published data regarding the safety and effectiveness of various therapies, and there continues to be a need for large randomized multicenter trials comparing newer therapies to treat this refractory condition.

Abstract
OBJECTIVE To establish a consensus which is practical and ready-to-use on investigations (ISE) and for management of status epilepticus (MSE) in adults using a modified Delphi approach. PATIENTS AND METHODS A 4-round modified Delphi approach was used. First and second rounds were conducted using Google® survey with structured statements and 6-point Likert scale response. Threshold agreement was set to ≥80%. Third round was a face-to-face meeting aimed to facilitate the development of approach algorithms for ISE and MSE. Fourth round was a final review asking participants to rate the algorithms post completion. RESULTS The panel consisted of 8 board-certified epileptologists along with 6 neurologists from main regional hospitals across Thailand. Thirty-seven statements for ISE and 68 statements for MSE were used for the Round I survey, 17/37 (45.9%) and 49/68 (72.1%) reached threshold agreement (≥80%). The average absolute-agreement intraclass correlation coefficients for ISE and MSE were 0.82 (95% CI 0.71, 0.89) and 0.81 (95% CI 0.73, 0.87), respectively; indicating good extent of consensus among participants. Upon Round II, further 10/18 (55.6%) for ISE and 10/19 (52.6%) for MSE reached agreement. In Round III, face-to-face point-by-point discussion was performed to generate approach algorithms. All (100%) provided positive responses with the algorithms post completion in Round IV. CONCLUSION A practical and ready-to-use consensus using modified Delphi approach on ISE and MSE was developed in a Thai regional hospital context. In real practice, this approach is more suitable and feasible for a localized setting when compared with totally adopting international guidelines.

Abstract
Autoimmune epilepsy is a newly emerging area of epilepsy. The concept of “autoimmune” as an etiology has recently been revisited thanks to advances in autoimmune encephalitis and precision medicine with immunotherapies. Autoimmune epilepsy presents with specific clinical manifestations, and various diagnostic approaches including cerebrospinal fluid analysis, neuroimaging, and autoantibody tests are essential for its differential diagnosis. The diagnosis is often indeterminate despite performing a thorough evaluation, and therefore empirical immunotherapy may be applied according to the judgment of the clinician. Autoimmune epilepsy often manifests as new-onset refractory status epilepticus (NORSE). A patient classified as NORSE should receive empirical immunotherapy as soon as possible. On the other hand, a morecautious, stepwise approach is recommended for autoimmune epilepsy that presents with episodic events. The type of autoimmune epilepsy is also an important factor to consider when choosing from among various immunotherapy options. Clinicians should additionally take the characteristics of antiepileptic drugs into account when using them as an adjuvant therapy. This expert opinion discusses the diagnostic and treatment approaches for autoimmune epilepsy from a practical point of view.

Abstract
Refractory status epilepticus is defined as persistent seizures despite appropriate use of two intravenous medications, one of which is a benzodiazepine. It can be seen in up to 40% of cases of status epilepticus with an acute symptomatic etiology as the most likely cause. New-onset refractory status epilepticus (NORSE) is a recently coined term for refractory status epilepticus where no apparent cause is found after initial testing. A large proportion of NORSE cases are eventually found to have an autoimmune etiology needing immunomodulatory treatment. Management of refractory status epilepticus involves treatment of an underlying etiology in addition to intravenous anesthetics and antiepileptic drugs. Alternative treatment options including diet therapies, electroconvulsive therapy, and surgical resection in case of a focal lesion should be considered. Short-term and long-term outcomes tend to be poor with significant morbidity and mortality with only one-third of patients reaching baseline neurological status.

Abstract
PURPOSE Our goal was to perform a scoping systematic review of the literature on the use of intravenous immunoglobulins (IVIG) for refractory status epilepticus (RSE) in adults. METHOD Articles from MEDLINE, BIOSIS, EMBASE, Global Health, Healthstar, Scopus, Cochrane Library, the International Clinical Trials Registry Platform, clinicaltrials.gov (inception to May 2016), reference lists of relevant articles, and gray literature were searched. The strength of evidence was adjudicated using both the Oxford and GRADE methodology by two independent reviewers. RESULTS Twenty-four original articles were identified. A total of 33 adult patients were described as receiving IVIG for RSE. Seizure reduction/control with IVIG occurred in 15 of the 33 patients (45.4%), with 1 (3.0%) and 14 (42.4%) displaying partial and complete responses respectively. No adverse events were recorded. CONCLUSION Oxford level 4, GRADE D evidence exists to suggest an unclear impact of IVIG therapy in adult RSE. Routine use of IVIG in adult RSE cannot be recommended at this time.

Abstract
BACKGROUND Our goal was to perform a scoping systematic review of the literature on the use of plasmapheresis or plasma exchange (PE) for refractory status epilepticus (RSE) in children. METHODS Articles from MEDLINE, BIOSIS, EMBASE, Global Health, Healthstar, Scopus, Cochrane Library, the International Clinical Trials Registry Platform, clinicaltrials.gov (inception to May 2016), reference lists of relevant articles, and gray literature were searched. The strength of evidence was adjudicated using both the Oxford and GRADE methodology by two independent reviewers. RESULTS Twenty-two original articles were identified, with 37 pediatric patients. The mean age of the patients was 8.3 years (age median: 8.5, range: 0.6 years-17 years). Seizure response to PE therapy occurred in 9 of the 37 patients (24.3%) included in the review, with 7 patients (18.9%) displaying resolution of seizures and 2 patients (5.4%) displaying a partial reduction in seizure volume. Twenty-eight of the 37 patients (75.7%) had no response to PE therapy. No adverse events were recorded. CONCLUSIONS Oxford level 4, GRADE D evidence exists to suggest little to no benefit of PE in pediatric RSE. Routine application of PE for pediatric RSE cannot be recommended at this time.

Abstract
PURPOSE Rasmussen's encephalitis (RE) is a hemispheric inflammatory disorder resulting in progressive epilepsy, hemiparesis, and cognitive decline. Controversy surrounds the most effective timing of surgery with respect to language dominance, functional status, and seizure outcome. We describe our experience with RE to inform treatment decisions. METHODS A retrospective chart review was performed in children diagnosed with RE from 1983 to 2012. RESULTS Thirteen consecutive cases were identified: six males and seven females with a mean age of 10.6 years (range 5-18). Nine patients received immunotherapy, with transient benefit in three, treatment-associated complications in two, and no difference in their mean time to treatment (5.38 vs 6.37 years p = 0.74) or long-term outcome. Mean follow-up was 5.6 years (range 0.58-12.25). There was no difference in outcome based on pre-operative duration of seizures. At last follow-up, 63 % of surgically treated patients achieved seizure freedom, 100 % had improved seizure control, 90 % had improved cognitive function, 36 % stopped medication, and 63 % tapered medication. Language improved in 83 % of patients with dominant disease. These findings were not associated with age at treatment. All surgical patients were ambulatory at last follow-up. CONCLUSIONS Hemispherotomy achieves good seizure control with cognitive improvement and ambulatory status post-operatively. Time to surgery and dominant disease were not associated with outcome, suggesting that hemispherotomy can be offered early or late, with expectations of good seizure control and functional outcome, even with dominant disease.

Abstract
OPINION STATEMENT Convulsive status epilepticus (CSE) is a medical emergency with an associated high mortality and morbidity. It is defined as a convulsive seizure lasting more than 5 min or consecutive seizures without recovery of consciousness. Successful management of CSE depends on rapid administration of adequate doses of anti-epileptic drugs (AEDs). The exact choice of AED is less important than rapid treatment and early consideration of reversible etiologies. Current guidelines recommend the use of benzodiazepines (BNZ) as first-line treatment in CSE. Midazolam is effective and safe in the pre-hospital or home setting when administered intramuscularly (best evidence), buccally, or nasally (the latter two possibly faster acting than intramuscular (IM) but with lower levels of evidence). Regular use of home rescue medications such as nasal/buccal midazolam by patients and caregivers for prolonged seizures and seizure clusters may prevent SE, prevent emergency room visits, improve quality of life, and lower health care costs. Traditionally, phenytoin is the preferred second-line agent in treating CSE, but it is limited by hypotension, potential arrhythmias, allergies, drug interactions, and problems from extravasation. Intravenous valproate is an effective and safe alternative to phenytoin. Valproate is loaded intravenously rapidly and more safely than phenytoin, has broad-spectrum efficacy, and fewer acute side effects. Levetiracetam and lacosamide are well tolerated intravenous (IV) AEDs with fewer interactions, allergies, and contraindications, making them potentially attractive as second- or third-line agents in treating CSE. However, data are limited on their efficacy in CSE. Ketamine is probably effective in treating refractory CSE (RCSE), and may warrant earlier use; this requires further study. CSE should be treated aggressively and quickly, with confirmation of treatment success with epileptiform electroencephalographic (EEG), as a transition to non-convulsive status epilepticus is common. If the patient is not fully awake, EEG should be continued for at least 24 h. How aggressively to treat refractory non-convulsive SE (NCSE) or intermittent non-convulsive seizures is less clear and requires additional study. Refractory SE (RSE) usually requires anesthetic doses of anti-seizure medications. If an auto-immune or paraneoplastic etiology is suspected or no etiology can be identified (as with cryptogenic new onset refractory status epilepticus, known as NORSE), early treatment with immuno-modulatory agents is now recommended by many experts.

Abstract
The term hemispherectomy refers to the complete removal or functional disconnection of a cerebral hemisphere. The technique was initially developed over 85 years ago to treat infiltrating brain tumors but is now used exclusively for medically refractory epilepsy. Hemispherectomy surgery has progressed from an extremely morbid procedure fraught with complications to a fairly routine one performed at most pediatric epilepsy centers with relatively low risk and great efficacy. The author reviews the history and evolution of hemispherectomy surgery, the relevant pathological conditions, as well as outcomes and complications.

Resective surgery in the treatment of super-refractory partial status epilepticus secondary to NMDAR antibody encephalitis. Eur J Paediatr Neurol 2014; 18:449-52.

Abstract
BACKGROUND Anti-NMDAR encephalitis is an increasingly described clinical entity in children, comprising 40% of all cases. We present a case of super-refractory status epilepticus secondary to anti-NMDAR encephalitis treated with emergent resective surgery. CASE STUDY A 7 years-old boy presented with progressive abnormal irritability. On the day after admission he had multiple seizures, characterized by head and eye version to the right. EEG revealed left parietal-occipital continuous paroxysmal activity. Anti-NMDAR antibodies were positive in CSF and serum. After almost 3 months in the Intensive Care Unit, in barbituric coma, and given the failure of all treatment regimens, a preoperative evaluation was conducted. Ictal SPECT showed significant hiperperfusion and brain FDG-PET a cortical hypometabolism in the left occipital lobe; a left occipital lobectomy was performed. In the next days it was possible to progressively suspend Thiopental. Currently, patient presents right homonymous hemianopsia, eats by his own hand but needs help in almost all other activities. DISCUSSION Status epilepticus (SE) in the setting of anti-NMDAR encephalitis is unusual but described. Whilst the role of surgery in the management of refractory focal epilepsy is established, it is seldom used in the treatment of SE. In the patient with refractory SE (RSE), awareness of surgery as a potentially life saving treatment is an important issue. To our knowledge, this is the first report of a partial RSE secondary to anti-NMDAR encephalitis treated with resective surgery and illustrates the need to consider anti-NMDAR encephalitis as a cause of super-refractory SE.

Abstract
Rasmussen encephalitis is a chronic inflammatory disease commonly seen in children. Hemispheric atrophy, intellectual disability, and hemiparesis are characteristics of this rare disease. The main pathological findings are chronic meningeal and parenchymal inflammation attributed to T lymphocytes. Plasmapheresis, immunomodulators, and immunosuppressives are commonly used for treatment. In this article, a patient suffering from Rasmussen encephalitis whose seizures were treated with prednisolone is discussed according to the literature.
