Abstract
INTRODUCTION Pediatric convulsive status epilepticus is one of the most common neurologic emergencies and should be managed by health care professionals as soon as possible based on current guidelines. This study aimed to determine the nursing approaches and management of pediatric convulsive status epilepticus from the perspective of emergency nurses in Turkey. METHODS A cross-sectional, multicenter study was conducted with 162 emergency nurses working in emergency departments in 35 different provinces in Turkey. The data were collected via an online form. Descriptive statistical methods were used in data analysis. RESULTS Most emergency nurses (72.2%) attempted an intravenous access immediately to administer antiseizure medications during the stabilization phase. Approximately half the emergency nurses stated that rectal diazePAM was frequently administered in the initial therapy phase and intravenous diazePAM was administered in the second therapy phase. The emergency nurses had most difficulties attempting intravenous access, determining status epilepticus types, and calming the parents. DISCUSSION As health care professionals and important members of the health team, emergency nurses have the responsibility to manage pediatric convulsive status epilepticus in the fastest and the most appropriate way based on current practice guidelines in emergency departments. When intravenous access is not available, nonintravenous benzodiazepines should be considered in the first-line treatment of pediatric convulsive status epilepticus, followed by immediate intravenous access.

Abstract
Status epilepticus (SE) is a neurological emergency that requires timely pharmacological therapy to cease seizure activity. The treatment approach varies based on the time and the treatment stage of SE. Benzodiazepines are considered the first-line therapy during the emergent treatment phase of SE. Antiseizure medicines such as phenytoin, valproic acid, and levetiracetam are recommended during the urgent treatment phase. These drugs appear to have a similar safety and efficacy profile, and individualized therapy should be chosen based on patient characteristics. Midazolam, propofol, pentobarbital, and ketamine are continuous intravenous infusions of anesthetic medications utilized in the refractory SE (RSE) period. The most efficacious pharmacotherapeutic treatments for RSE and superrefractory status epilepticus are not clearly defined.

Abstract
Patients with advanced cancer are faced with many devastating symptoms in the last weeks and days of life, such as pain, delirium, dyspnea, bronchial hypersecretions (death rattle), and intractable seizures. Symptom management in the last weeks of life can be particularly challenging because of the high prevalence of delirium complicating symptom assessment, high symptom expression secondary to psychosocial and spiritual factors, limited life-expectancy requiring special considerations for prognosis-based decision-making, and distressed caregivers. There is a paucity of research involving patients in the last weeks of life, contributing to substantial variations in clinical practice. In this narrative review, we shall review the existing literature and provide a practical approach to in-patient management of several of the most distressing physical symptoms in the last weeks to days of life.

Abstract
OBJECTIVE The objective of this study was to compare statewide prehospital protocols for the management of pediatric seizures. METHODS We performed a descriptive analysis comparing statewide protocols for emergency medical services management of pediatric seizures within the United States, excluding states for which no statewide protocol/model was available. We compared antiepileptic drugs (AEDs), routes and doses of administration, and differences in febrile seizure management. RESULTS Of 50 states, 34 had either statewide protocols or models and were included. All had a protocol for the management of seizures and provided specific recommendations for the management of pediatric seizures. Twelve states (35%) preferentially recommended midazolam over other benzodiazepines. Thirty-two (94%) of 34 allowed for use of midazolam, with variable use of other AEDs. All allowed for use of intramuscular AED. Twenty-six (77%) allowed for intranasal AED. Nine (27%) allowed emergency medical services to administer a patient's own abortive AED, and 6 (18%) allowed for use of a patient's vagal nerve stimulator, when present. There was a wide variability with respect to dosing ranges for medications. Thirty-two (94%) of 34 included blood glucose measurement within the protocol. Twenty-one protocols (62%) provided recommendations for febrile seizures, including recommending active/passive cooling (8/34, 24%) and antipyretic administration (9/34, 26%). CONCLUSIONS All statewide protocols carried specific guidelines for the prehospital management of pediatric seizures; however, there was wide variability with respect to specific AEDs, routes of administration, and drug dosages. In addition to broader availability of statewide guidance, areas of potential protocol improvement and research include AED dose optimization, reprioritization of blood glucose, and greater emphasis on intranasal or intramuscular medication dosing.

Abstract
BACKGROUND Acute seizure activity might cause complications including bodily harm, progression to status epilepticus, and poor quality of life in children. The introduction of a venous line may be difficult in children with seizures which would delay the initiation of treatment. Rectal drug administration can be socially awkward for patients and providers. Intranasal (IN) midazolam offers a valuable substitute that is easier and faster to administer. OBJECTIVE To assess the efficacy, safety, and acceptability of intranasal midazolam in children with acute seizure when compared to conventional IV or rectal benzodiazepine (BDZ). METHODS PubMed, google scholar, websites clinicaltrials.gov and the WHO-international clinical trials registry platform, were searched. Randomized controlled/prospective randomized trials comparing IN midazolam against IV/rectal BDZ in the treatment of acute seizures in pediatric patients were included in the meta-analysis. RESULTS Data of 10 studies were quantitatively analyzed. Intranasal midazolam (n = 169) when compared to IV/rectal BDZ (n = 161) has a shorter interval between hospital arrival and seizure cessation {(mean difference = -3.51; 95% CI [-6.84, -0.18]) P = 0.04}. Regarding time to seizure cessation after midazolam (n = 326) or BDZ (n = 322) administration, there is no significant difference between the two groups {(mean difference = -0.03; 95% CI [-1.30, 1.25]), P = 0.97} and both are equally effective for controlling acute seizures (odds ratio = 1.06; 95% CI [0.43, 2.63]; n = 737). CONCLUSION In children with acute seizures, IN midazolam is equally effective in aborting seizure and decreases the total time from hospital arrival and cessation of seizures, eventually leading to faster cessation of seizure as compared to IV/rectal BDZ.

Abstract
Time plays a major role in seizure evaluation and treatment. Acute repetitive seizures and status epilepticus are medical emergencies that require immediate assessment and treatment for optimal therapeutic response. Benzodiazepines are considered the first-line agent for rapid seizure control. Thus, various routes of administration of benzodiazepines have been studied to facilitate a quick, effective, and easy therapy administration. Choosing the right agent may vary based on the drug and route properties, patient’s environment, caregiver’s skills, and drug accessibility. The pharmacokinetic and pharmacodynamic aspects of benzodiazepines are essential in the decision-making process. Ultimately, agents and routes that give the highest bioavailability, fastest absorption, and a modest duration are preferred. In the outpatient setting, intranasal and buccal routes appear to be equally effective and more rapidly administered than rectal diazepam. On the other hand, in the inpatient setting, if available, the IV route is ideal for benzodiazepine administration to avoid any potential absorption delay. In this article, we will provide an overview and comparison of the various routes of benzodiazepine administration for acute control of repetitive seizures and status epilepticus.

Abstract
Objectives The main aim is to find out the clinical feature and outcome of status epilepticus (SE) in children managed in a teaching hospital. The secondary aim is to identify the risk factors influencing the adverse outcomes. Methods In this prospective cohort, children aged 1 month to 14 years with SE as per the International League Against Epilepsy’s new guideline (2016) who presented to the emergency department during the period of November 2017 to October 2019 were enrolled. Clinical profile, treatment, and outcome of cases (n = 94) were noted. Results The majority of children, 60 (63.82%), were less than five years of age. Prior history of seizures was present in 33 (35.1%) cases, whereas 61 (64.9%) cases presented with SE as the first episode of seizure. In 14 (42.4%) previous seizure cases, SE was due to drug default. No response to first-line antiepileptic drug (AED) was seen in 84 (89.37%) cases. Acute symptomatic etiology was the commonest etiology of SE in 64 (68%) cases, of which neuro-infections accounted for 44 (46.80%) cases. Longer duration (>60 minutes) of status (p < 0.01), ventilator support (p < 0.0001), and circulatory impairment (p < 0.0001) were attributable risk factors for mortality. A total of 28 children died (mortality rate, 29.8%), and 11 showed the persistence of their neuro-deficit. Conclusions Neuro-infection is the most common etiology of SE in children. Longer duration of SE, more lag time for receiving the first AED, respiratory failure, and presence of shock are independent predictors for poor outcome. Hence, cessation of convulsion at the earliest leads to improved outcomes.

Abstract
OBJECTIVE To develop recommendations for the management of patients with primary or secondary generalized tonic-clonic seizures (GTCS) based on best evidence and experience. METHODS The Delphi methodology was followed. A multidisciplinary panel of 10 experts was established, who defined the scope, users and preliminary recommendations. Systematic and narrative reviews of the current literature were performed to assess data on the risk of sudden unexpected death in epilepsy and the efficacy and safety of add-on therapy in patients with GTCS. Twenty-five definitive recommendations were generated which were then graded on a scale of 1 (totally disagree) to 10 (totally agree) by the experts and 45 neurologists. Consensus was reached if at least 70% of the participants applied a score of ≥7. Each recommendation was then assigned a level of evidence, a grade of agreement and a grade of recommendation. The entire process was supervised by an expert methodologist. RESULTS Overall, 24 out of 25 recommendations achieved consensus. These included specific recommendations on diagnosis, evaluation and treatment. The recommendations also emphasized the importance of proper psychological evaluation and effective communication between patients and health professionals, and the importance of patient and family education and support. SIGNIFICANCE The recommendations generated by this consensus can be used as a guide for the diagnosis and management of patients with GTCS.

Abstract
Objective We sought to evaluate the efficacy and tolerability of intranasal midazolam (in‐MDZ) as first‐line inhospital therapy in patients with status epilepticus (SE) during continuous EEG recording. Methods Data on medical history, etiology and semiology of SE, anticonvulsive medication usage, efficacy and safety of in‐MDZ were retrospectively reviewed between 2015 and 2018. Time to end of SE regarding the administration of in‐MDZ and ß‐band effects were analyzed on EEG and with frequency analysis. Results In total, 42 patients (mean age: 52.7 ± 22.7 years; 23 females) were treated with a median dose of 5 mg of in‐MDZ (range: 2.5–15 mg, mean: 6.4 mg, SD: 2.6) for SE. The majority of the patients suffered from nonconvulsive SE (n = 24; 55.8%). In total, 24 (57.1%) patients were responders, as SE stopped following the administration of in‐MDZ without any other drugs being given. On average, SE ceased on EEG at 05:05 (minutes:seconds) after the application of in‐MDZ (median: 04:56; range: 00:29–14:53; SD:03:13). Frequency analysis showed an increased ß‐band on EEG after the application of in‐MDZ at 04:07 on average (median: 03:50; range: 02:20–05:40; SD: 01:09). Adverse events were recorded in six patients (14.3%), with nasal irritations present in five (11.9%) and prolonged sedation occurring in one (2.6%) patient. Conclusions This pharmaco‐EEG–based study showed that in‐MDZ is effective and well‐tolerated for the acute treatment of SE. EEG and clinical effects of in‐MDZ administration occurred within 04:07 and 5:05 on average. Intranasal midazolam appears to be an easily applicable and rapidly effective alternative to buccal or intramuscular application as first‐line treatment if an intravenous route is not available.

Abstract
Epilepsy is one of the most common serious brain conditions, affecting over 70 million people worldwide. Its incidence has a bimodal distribution with the highest risk in infants and older age groups. Progress in genomic technology is exposing the complex genetic architecture of the common types of epilepsy, and is driving a paradigm shift. Epilepsy is a symptom complex with multiple risk factors and a strong genetic predisposition rather than a condition with a single expression and cause. These advances have resulted in the new classification of epileptic seizures and epilepsies. A detailed clinical history and a reliable eyewitness account of a seizure are the cornerstones of the diagnosis. Ancillary investigations can help to determine cause and prognosis. Advances in brain imaging are helping to identify the structural and functional causes and consequences of the epilepsies. Comorbidities are increasingly recognised as important aetiological and prognostic markers. Antiseizure medication might suppress seizures in up to two-thirds of all individuals but do not alter long-term prognosis. Epilepsy surgery is the most effective way to achieve long-term seizure freedom in selected individuals with drug-resistant focal epilepsy, but it is probably not used enough. With improved understanding of the gradual development of epilepsy, epigenetic determinants, and pharmacogenomics comes the hope for better, disease-modifying, or even curative, pharmacological and non-pharmacological treatment strategies. Other developments are clinical implementation of seizure detection devices and new neuromodulation techniques, including responsive neural stimulation.

Abstract
First responders and health care providers must prepare to provide care for patients poisoned by acetylcholinesterase (AchE) inhibitor chemical warfare agents or pesticides. However, pre-deployed medical countermeasures (MCMs) may not be sufficient due to production and delivery interruption, rapid depletion of contents during a response, expiration of MCM components, or lack of local availability of approved MCMs. To augment supplies of community-based and forward-deployed nerve agent countermeasures, the American College of Medical Toxicology (ACMT) supports several strategies: (1) The use of expired atropine, diazepam, and pralidoxime auto-injectors and vials if non-expired drugs are unavailable; and (2) Investigation, development, and identification of alternative countermeasures-commonly stocked drugs that are not approved for nerve agent poisoning but are in the same therapeutic class as approved drugs.

Pre-hospital midazolam for benzodiazepine-treated seizures before and after the Rapid Anticonvulsant Medication Prior to Arrival Trial: A national observational cohort study.

Abstract
Background Implementation of evidence-based treatment for pre-hospital status epilepticus can improve outcomes. We hypothesized that publication of a pivotal pre-hospital clinical trial (RAMPART), demonstrating superiority of intramuscular midazolam over intravenous lorazepam, altered the national utilization rates of midazolam for pre-hospital benzodiazepine-treated seizures, while upholding its safety and efficacy outside the trial setting. Methods and findings This is a retrospective, observational cohort study of pre-hospital patient encounters throughout the United States in the National Emergency Medicine Services Information System database, from January 2010 through December 2014. We compared the rates and odds of midazolam use as first-line treatment among all adult and pediatric benzodiazepine-treated seizures before and after RAMPART publication (February 2012). Secondary analyses were conducted for rates of airway interventions and rescue therapy, as proxies for safety and efficacy of seizure termination. 156,539 benzodiazepine-treated seizures were identified. Midazolam use increased from 26.1% in January 2010 to 61.7% in December 2014 (difference +35.6%, 95% CI, 32.7%-38.4%). The annual rate of midazolam adoption increased significantly from 5.9% per year to 8.9% per year after the publication of RAMPART (difference +3.0% per year; 95%CI, 1.6%-4.5% per year; adjusted OR 1.24; 95%CI, 1.17–1.32). Overall frequency of rescue therapy and airway interventions changed little after the publication of RAMPART. Conclusions These data are consistent with effective, ongoing, but incomplete clinical translation of the RAMPART results. The effects of the trial, however, cannot be isolated. The study was limited by broad inclusion of all benzodiazepine-treated seizures as well as a lack of information on route of drug of administration. The safety and effectiveness of midazolam for benzodiazepine-treated seizures in prehospital clinical practice appear consistent with trial data, which should encourage continuing increases in utilization.
