Refractory and super-refractory status epilepticus in children and adolescents: A population-based study. Seizure 2024; 120:116-123. [PMID: 38941802 DOI: 10.1016/j.seizure.2024.06.023] [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: 04/19/2024] [Revised: 06/10/2024] [Accepted: 06/23/2024] [Indexed: 06/30/2024] Open
Abstract
PURPOSE Refractory (RSE) and super-refractory status epilepticus (SRSE) are serious medical emergencies whose long-term outcomes depend on the timeliness of their management. Population-based clinical and epidemiological data on these conditions are sparse. We aimed to provide a detailed description of the epidemiology and clinical course of RSE and SRSE in children and adolescents and identify potential prognostic biomarkers. METHODS In this retrospective population-based study, patients aged one month to 18 years who fulfilled the RSE/SRSE diagnostic criteria and were admitted to the intensive care unit of Haukeland University Hospital from 2012 to 2021 were considered eligible. Detailed clinical and laboratory findings along with information on management and outcomes were systematically analyzed. RESULTS Forty-three patients with 52 episodes of RSE/SRSE were identified. The incidence rate was 3.13 per 100,000 per year. The median time from SE onset to the administration of the first rescue drug was 13 min, and from the first rescue drug to second- and third-line treatments, 83 and 66 min, respectively. All patients were alive at discharge. CONCLUSION Delays in treatment were observed in various stages of the clinical course of RSE/SRSE. Improvement measures targeting the prompt administration of recuse mediation and subsequent treatment escalation are needed.

Abstract
BACKGROUND AND PURPOSE We aimed to explore structural connectivity in status epilepticus. METHODS We enrolled participants who underwent diffusion tensor imaging. We applied graph theory to investigate structural connectivity. We compared the structural connectivity measures between patients and healthy controls and between patients with poor (modified Rankin Scale [mRS] >3) and good (mRS ≤3) admission outcomes. RESULTS We enrolled 28 patients and 31 healthy controls (age 65.5 vs.62.0 years, p = .438). Of these patients, 16 and 12 showed poor and good admission outcome (age 65.5 vs.62.0 years, p = .438). The assortative coefficient (-0.113 vs. -0.121, p = .021), mean clustering coefficient (0.007 vs.0.006, p = .009), global efficiency (0.023 vs.0.020, p = .009), transitivity (0.007 vs.0.006, p = .009), and small-worldness index (0.006 vs.0.005, p = .021) were higher in patients with status epilepticus than in healthy controls. The assortative coefficient (-0.108 vs. -0.119, p = .042), mean clustering coefficient (0.007 vs.0.006, p = .042), and transitivity (0.008 vs.0.007, p = .042) were higher in patients with poor admission outcome than in those with good admission outcome. MRS score was positively correlated with structural connectivity measures, including the assortative coefficient (r = 0.615, p = .003), mean clustering coefficient (r = 0.544, p = .005), global efficiency (r = 0.515, p = .007), transitivity (r = 0.547, p = .007), and small-worldness index (r = 0.435, p = .024). CONCLUSION We revealed alterations in structural connectivity, showing increased integration and segregation in status epilepticus, which might be related with neuronal synchronization. This effect was more pronounced in patients with a poor admission outcome, potentially reshaping our understanding for comprehension of status epilepticus mechanisms and the development of more targeted treatments.

Abstract
Background Although the association between neurodegenerative diseases, such as dementia, and traumatic brain injury (TBI) has long been known, the association between dementia and TBI with epilepsy has been controversial. Aim This data-driven population-based study is designed to investigate the association between dementia and epilepsy after TBI within a 2-year period. Methods This case-control cohort study was conducted using the Longitudinal Health Insurance Database 2000 (LHID2000). We included 784 individuals ambulatory or hospitalized for TBI with epilepsy from 2001 to 2011, compared with 2992 patients with TBI without epilepsy who were matched for characteristics including sex, age, and healthcare resource use index date. Every participant was followed up for 5 years to ascertain any dementia development. Data were stratified and analyzed using the Cox proportional hazards regression. Results Through the 5-year follow-up period, 39 patients (5.21%) with TBI with epilepsy and 55 (1.53%) with TBI without epilepsy developed dementia. TBI with epilepsy was independently associated with a >3.03 times risk of dementia after correcting for age, sex, and comorbidities. Conclusion These findings suggest an increased risk of dementia in patients with TBI with epilepsy. Our research recommends that individuals with TBI and epilepsy be monitored more intensively.

Abstract
This study aimed to group acute symptomatic etiologies of consecutive episodes of status epilepticus (SE) into different subcategories and explore their associations with clinical outcome. Etiologies were first categorized as "acute," "remote," "progressive," "SE in defined electroclinical syndromes," and "unknown." Four subcategories of acute etiologies were then defined: (1) withdrawal, low levels, or inappropriate prescription of antiseizure medications, or sleep deprivation in patients with pre-existing epilepsy; (2) acute insults to central nervous system (CNS; "acute-primary CNS"); (3) CNS pathology secondary to metabolic disturbances, systemic infection, or fever ("acute-secondary CNS"); and (4) drug/alcohol intoxication or withdrawal. Poor outcome at discharge, defined as worsening of clinical conditions (modified Rankin Scale [mRS] at discharge higher than mRS at baseline), was reported in 55.6% of cases. The etiological categories of acute-primary CNS (odds ratio [OR] = 3.61, 95% confidence interval [CI] = 2.11-6.18), acute-secondary CNS (OR = 1.80, 95% CI = 1.11-2.91), and progressive SE (OR = 2.65, 95% CI = 1.57-4.47), age (OR = 1.05, 95% CI = 1.04-1.06), nonconvulsive semiology with coma (OR = 3.06, 95% CI = 1.52-6.17), and refractoriness (OR = 4.31, 95% CI = 2.39-7.77) and superrefractoriness to treatment (OR = 8.24, 95% CI = 3.51-19.36) increased the odds of poor outcome. Heterogeneity exists within the spectrum of acute symptomatic causes of SE, and distinct etiological subcategories may inform about the clinical outcome.

Abstract
Background: Status epilepticus (SE) is a neurologic emergency that can result in serious morbidity and mortality. Recent studies have suggested underdosing of both benzodiazepines (BZDs) and antiseizure medications (ASM) which may result in poorer outcomes. Objectives: This study aims to determine the dose of BZDs and levetiracetam given in our emergency department for episodes of SE and determine the outcomes associated with this dosing. Methods: We conducted a retrospective cohort study of all adult patients with SE admitted to our hospital from 2017 to 2020. We collected demographic data, type of SE, dose of BZD and levetiracetam, and outcomes which included mortality and a calculated Glasgow outcome scale (GOS). We compared outcomes of patients with SE who received adequate dosing (according to practice guidelines) to those who did not. Results: 111 adult patients were included of whom 91% were seen initially in our emergency department. 75% had convulsive SE on presentation. Approximately 55% and 68% of patients did not receive an appropriate dose of BZD or levetiracetam, respectively. Inadequate dosing of BZD was associated with worse clinical outcomes based on GOS (43.6% favorable outcome vs 62.5% with adequate dosing P = .046 (95% CI, 1.01-4.60)) and inadequate dosing of both drugs was also associated with a worse GOS outcome (HR, 2.91 (95% CI, 1.05-9.67, P = .02). No difference was found in length of stay or mortality alone. Conclusion: Our study found inadequate dosing of drugs to treat SE in adults was common in our institution and was associated with worse outcomes.

Abstract
Objective Vagus nerve stimulation (VNS) is a palliative surgery for drug-resistant epilepsy. The two objectives of this study were to (1) determine the seizure type most responsive to VNS and (2) investigate the preventive effect on status epilepticus (SE) recurrence. Methods We retrospectively reviewed 136 patients with drug-resistant epilepsy who underwent VNS implantation. We examined seizure outcomes at 6, 12, and 24 months following implantation of VNS as well as at the last visit to the Juntendo Epilepsy Center. Univariate analysis and multivariate logistic regression models were used to estimate the prognostic factors. Results 125 patients were followed up for at least 1 year after VNS implantation. The percentage of patients with at least a 50% reduction in seizure frequency compared with prior to VNS implantation increased over time at 6, 12, and 24 months after VNS implantation: 28, 41, and 52%, respectively. Regarding overall seizure outcomes, 70 (56%) patients responded to VNS. Of the 40 patients with a history of SE prior to VNS implantation, 27 (67%) showed no recurrence of SE. The duration of epilepsy, history of SE prior to VNS implantation and seizure type were correlated with seizure outcomes after VNS implantation in univariate analysis (p = 0.05, p < 0.01, and p = 0.03, respectively). In multivariate logistic regression analysis, generalized seizure was associated with VNS response [odds ratio (OR): 4.18, 95% CI: 1.13-15.5, p = 0.03]. A history of SE prior to VNS implantation was associated with VNS non-responders [(OR): 0.221, 95% CI: 0.097-0.503, p < 0.01]. The duration of epilepsy, focal to bilateral tonic-clonic seizure and epileptic spasms were not significantly associated with VNS responders (p = 0.07, p = 0.71, and p = 0.11, respectively). Conclusion Following 125 patients with drug-resistant epilepsy for an average of 69 months, 56% showed at least 50% reduction in seizure frequency after VNS implantation. This study suggests that generalized seizure is the most responsive to VNS, and that VNS may reduce the risk of recurrence of SE. VNS was shown to be effective against generalized seizure and also may potentially influence the risk of further events of SE, two marker of disease treatment that can lead to improved quality of life.

Abstract
OBJECTIVE Possible long-term consequences of status epilepticus (SE) include cognitive and behavioral impairment and the development of chronic epilepsy. However, these aspects have not been systematically studied in clinical practice. We aimed to evaluate long-term seizure recurrence after SE and the potential risk factors for their development. METHODS Data were obtained from a prospective registry of all SE episodes occurring in adult patients who attended our center from February 2011 to April 2022. Clinical data, electroencephalographic findings, treatment, and long-term data were prospectively recorded. We performed a cross-sectional study of consecutive SE patients without previous epilepsy diagnosis, and analyzed the development of unprovoked remote seizures. RESULTS A total of 849 patients were registered in the database. After excluding in-hospital mortality (198/849, 23.3%) and patients with prior epilepsy history (291/849, 44.7%), 360 patients (42.4%) with a first SE episode were included. The median age was 68 years (interquartile range [IQR] = 56-79), and 176 patients (48.9%) were women. The median time to first-line treatment initiation was 2 h (IQR = .7-7.4), and it was correlated with SE duration (R = .375, p < .001). One hundred nine patients (30.3%) presented unprovoked seizures during a median follow-up of 1.8 years (IQR = .5-4.3). After adjusting for identifiable confounders in a multivariable Cox regression analysis, progressive symptomatic etiology (hazard ratio [HR] = 1.97, 95% confidence interval [CI] = 1.17-3.33, p = .011), time to first-line treatment initiation > 1.5 h (HR = 1.89, 95% CI = 1.25-2.87, p = .003), and superrefractory SE (HR = 2.34, 95% CI = 1.26-4.33, p = .007) were independently associated with a greater risk of unprovoked seizure recurrence. In contrast, older patients (HR = .99, 95% CI = .97-.99, p = .021) and an acute symptomatic etiology (HR = .44, 95% CI .28-.68, p < .001) were at lower risk of unprovoked seizure recurrence. SIGNIFICANCE The etiology of SE, the delay in initiating SE treatment, and the presence of superrefractoriness have been identified as potentials factors associated with unprovoked remote seizures following a new onset SE. Therefore, prompt and appropriate management should be applied to avoid seizure recurrence.

Abstract
Pediatric convulsive status epilepticus (cSE) is a neurologic emergency with potential for morbidity and mortality. Rapid treatment and escalation of therapies to achieve early seizure control is paramount in preventing complications and providing the best patient outcomes. Although guidelines recommend early treatment, cessation of out-of-hospital SE is undermined by treatment delay and inadequate dosing. Logistical challenges include prompt seizure recognition, first-line benzodiazepine (BZD) availability, comfort and expertise in administration of BZD, and timely arrival of emergency personnel. In-hospital, SE onset is additionally impacted by delays to first- and second-line treatment and availability of resources. This review presents an evidence-based, clinically oriented review of pediatric cSE, including its definitions and treatments. It provides evidence and rationale for timely treatment of first-line BZD treatment followed by prompt escalation to second-line antiseizure medication therapies for established SE. Treatment delays and barriers to care are discussed, with practical considerations for opportunities for areas of improvement in the initial treatment of cSE.

Abstract
Patients with epilepsy carry a risk of premature death which is on average two to three times higher than in the general population. The risk of death is not homogenously distributed over all ages, etiologies, and epilepsy syndromes. People with drug resistant seizures carry the highest risk of death compared to those who are seizure free, whose risk is similar as in the general population. Most of the increased risk is directly related to the cause of epilepsy itself. Sudden unexplained death in epilepsy patients (SUDEP) is the most important cause of epilepsy-related deaths especially in the young and middle-aged groups. Population based studies with long-term follow up demonstrated that the first years after diagnosis carry the highest risk of death, while in the later years the mortality decreases. Improved seizure control and being exposed to a specialized comprehensive care centre may help to reduce the risk of death in patients with epilepsy. The mortality of status epilepticus is substantially increased with case fatality rates between 4.6% and 39%, depending on its cause and duration, and the age of the population studied. The epidemiological data on overall and cause specific mortality as well as their determinants and risk factors are critically reviewed and methodological issues pertinent to the studies on mortality of epilepsy and Status epilepticus are discussed.

Verma A, Kumar A, Pathak P, Mishra AK. Clinical Profile and Predictors of In-Hospital Mortality in De Novo Convulsive Status Epilepticus in the Elderly Populace. J Epilepsy Res 2022; 12:48-52. [PMID: 36685739 PMCID: PMC9830029 DOI: 10.14581/jer.22009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 07/25/2022] [Accepted: 08/14/2022] [Indexed: 12/30/2022] Open
Abstract
Background and Purpose De novo status epilepticus (SE) had worse outcome in comparison to the patients with SE who had previous history of epilepsy. The aim of the present study was to identify clinical features of de novo convulsive status epilepticus (CSE) and the predictors of in-hospital mortality. Methods Seventy-seven elderly (≥60 years of age) hospitalized patients with de novo CSE were evaluated for clinical profile, aetiologies and predictors of in-hospital mortality. Results The average age of the participants in the study was 65.96±6.72 years. In de novo CSE, the most common aetiologies were acute symptomatic in 68.8% of cases, followed by remote symptomatic in 24.7%. In-hospital mortality in the de novo CSE in the elderly was 30 (38.9%) in our series. Stroke was the leading cause of death among them (acute stroke in 23 cases and old infarct in 1 case), followed by post-traumatic (n=4) and CNS infection (n=2). On multivariate analysis, it was found that variables significantly related to mortality in de novo CSE were low Glasgow coma scale (GCS) (adjusted odds ratio [AOR], 53.5; 95% confidence interval [CI], 5.17-555.14; p=0.001) and lack of response to first line treatment (AOR, 0.06; 95% CI, 0.01-0.50; p=0.01). Conclusions In-hospital mortality in de novo CSE patients was linked to a low GCS and a lack of response to first-line therapy. The most efficient strategy to prevent in-hospital mortality in the elderly is to treat de novo CSE promptly and aggressively in the setting of stroke.

Abstract
INTRODUCTION Status epilepticus (SE) is one of the most common neurologic emergencies and is associated with significant morbidity and mortality. The underlying cause of SE varies between patients with epilepsy and those presenting without. The aim of this study was to evaluate the epidemiology, risk factors and outcomes of patients presenting with convulsive SE in the emergency department (ED) of a tertiary hospital in Mogadishu. METHODS This was a cross-sectional study conducted between July 2021 and June 2022. The study included both patients with epilepsy and those without epilepsy presenting to the ED with SE. Risk factors and underlying etiologies were evaluated in the patients in both the pediatric group (0-18 years) and adult group (18 years and above). Clinical history, neurologic examinations, neuroimaging, electroencephalography findings, and laboratory investigations were all evaluated. RESULTS The mean age for pediatric patients was 6 (SD±4.7), while the mean age for adult patients was 38 (SD±10.4). About 33 (36%) of the subjects had previous history of epilepsy, while 59 (64%) presented to the ED with their first seizure. About 80 (87%) had generalized seizure while 12 (13%) had focal seizure. Poor antiepileptic compliance was the most common risk factor for SE 20 (21.7%), followed by CNS infections 14 (15%), and prolonged febrile seizures 7 (7.6%). Poor antiepileptic drug compliance, cerebrovascular disorders, electrolyte imbalance, metabolic conditions, and drug abuse were the most common underlying etiologies of SE in patients older than 18 years. Prolonged febrile seizure, meningitis, encephalitis, systemic infections, and structural brain abnormalities were the most common underlying etiologies of SE in patients younger than 18 years. CONCLUSION CNS infections, CVDs, metabolic disturbances, electrolyte imbalances, and systemic infections are major etiological risk factors of SE in patients without prior history of epilepsy. Medication adherence was the major etiological risk factor for SE identified in patients with epilepsy.

Abstract
Convulsive status epilepticus (CSE) is the most common neurological emergency in children and the second most common neurological emergency in adults. Mortality is low, but morbidity, including neuro-disability, learning difficulties, and a de-novo epilepsy, may be as high as 22%. The longer the duration of CSE, the more difficult it is to terminate, and the greater the risk of morbidity. Convulsive status epilepticus is usually managed using specific national or local algorithms. The first-line treatment is administered when a tonic-clonic or focal motor clonic seizure has lasted five minutes (impending or premonitory CSE). Second-line treatment is administered when the CSE has persisted after two doses of a first-line treatment (established CSE). Randomised clinical trial (RCT) evidence supports the use of benzodiazepines as a first-line treatment of which the most common are buccal or intra-nasal midazolam, rectal diazepam and intravenous lorazepam. Alternative drugs, for which there are considerably less RCT data, are intra-muscular midazolam and intravenous clonazepam. Up until 2019, phenobarbital and phenytoin (or fosphenytoin) were the preferred second-line treatments but with no good supporting RCT evidence. Robust RCT data are now available which has provided important information on second-line treatments, specifically phenytoin (or fosphenytoin), levetiracetam and sodium valproate. Lacosamide is an alternative second-line treatment but with no supporting RCT evidence. Current evidence indicates that first, buccal or intranasal midazolam or intravenous lorazepam are the most effective and the most patient and carer-friendly first-line anti-seizure medications to treat impending or premonitory CSE and second, that there is no difference in efficacy between levetiracetam, phenytoin (or fosphenytoin) or sodium valproate for the treatment of established CSE. Pragmatically, levetiracetam or sodium valproate are preferred to phenytoin (or fosphenytoin) because of their ease of administration and lack of serious adverse side-effects, including potentially fatal cardiac arrhythmias. Sodium valproate must be used with caution in children aged three and under because of the rare risk of hepatotoxicity and particularly if there is an underlying mitochondrial disorder.

Abstract
Background In 2015, the International League Against Epilepsy proposed a new conceptual definition of status epilepticus (SE) with two operational dimensions (t1 and t2) to guide emergency treatment. The purpose of this study was to compare clinical characteristics and prognoses of patients at these two different time points. Methods We conducted a prospective observational cohort study of consecutive adults diagnosed with SE. In case of convulsive SE, t1 is 5 min and t2 is 30 min, whereas in case of focal SE with impaired consciousness, t1 is 10 min, t2 is 60 min. Data on clinical characteristics, including age, gender, history of prior seizures, neuroimaging, semiology, duration, and etiology of SE, were collected. The primary outcome was mortality, with seizure recurrence as a secondary measure, and functional status as tertiary outcome of enrolled patients at 3 months after SE onset. Results We screened one hundred patients with SE, with a median age of 66 years and 61% were male. Fifty-six (56.0%) patients reached t1 of SE, while 44 (44.0%) reached t2 of SE. Convulsive SE (52.0%, n = 52) was more common than focal SE with impaired consciousness (48.0%, n = 48). Status epilepticus secondary to an acute symptomatic process was the most common (50%, n = 50). Patients meeting t2 of SE demonstrated a remarkably increased risk of mortality (unadjusted analysis-RR 3.606, 95%CI 1.552–8.376, p = 0.003; adjusted analysis-RR 2.924, 95%CI 1.221–7.003, p = 0.016) and unfavorable functional status (unadjusted analysis-RR 1.803, 95%CI 1.280–2.539, p = 0.001; adjusted analysis-RR 1.664, 95%CI 1.184–2.340, p = 0.003) at 3 months compared to those who only reached t1 of SE. Patients reaching t2 of SE were more likely to experience seizure recurrence, however, there was no significant difference between the two cohorts. Conclusions Our study provides strong support for the new definition of SE. Patients meeting t2 of SE tend to have a remarkably increased risk of mortality and unfavorable functional outcomes compared to those who only reached t1 of SE. Furthermore, patients were likely to experience seizure recurrence after undergoing an episode of SE. Physicians must be educated about prompt recognition and appropriate management of SE.

Abstract
BACKGROUND AND OBJECTIVES The functional outcome and mortality of post-stroke epilepsy (PSE) patients have not been assessed in a prospective study. Previous reports have suggested that PSE patients may suffer from prolonged functional deterioration following a seizure. In the current study, we prospectively investigated the functional outcome and mortality of PSE patients and analyzed the impact of seizure recurrence on the outcomes. METHODS This is part of the Prognosis of Post-Stroke Epilepsy (PROPOSE) study, a multicenter, prospective observational cohort study, where 392 PSE patients (at least one unprovoked seizure more than 7 days after the onset of the last symptomatic stroke) were followed for at least 1 year at eight hospitals in Japan. The current study included only PSE patients with a first-ever seizure and assessed their functional decline and mortality at 1 year. Functional decline was defined as an increase in modified Rankin Scale (mRS) score at 1 year compared to baseline, excluding death. The associations between seizure recurrence and the outcomes were analyzed statistically. RESULTS A total of 211 patients (median age of 75 years; median mRS score of 3) were identified. At 1 year, 50 patients (23.7%) experienced seizure recurrence. Regarding outcomes, 25 patients (11.8%) demonstrated functional decline, and 20 (9.5%) had died. Most patients died of pneumonia or cardiac disease (seven patients each), and no known causes of death were directly related to recurrent seizures. Seizure recurrence was significantly associated with functional decline (odds ratio 2.96 [95% CI 1.25-7.03], P=0.01), even after adjusting for potential confounders (adjusted odds ratio 3.26 [95% CI 1.27-8.36], P=0.01), but not with mortality (odds ratio 0.79 [95% CI 0.18-2.61], P=0.79). Moreover, there was a significant trend where patients with more recurrent seizures were more likely to have functional decline (8.7%, 20.6%, and 28.6% in none, 1, and 2 or more recurrent seizures, respectively; P=0.006). DISCUSSION One-year functional outcome and mortality of PSE patients were poor. Seizure recurrence was significantly associated with functional outcome, but not with mortality. Further studies are needed to ascertain whether early and adequate anti-seizure treatment can prevent the functional deterioration of PSE patients.

Abstract
AbstractStatus epilepticus (SE) is a common fatal neurological disease with high morbidity and mortality. Even if a large proportion of patients might be relieved from anti-seizure medications, sedatives and anesthetics, some still remain out of control. The ketogenic dietary (KD) has been proven useful in patients refractory to medications and/or who have failed to respond to surgical intervention. Recently, KD has shown beneficial therapeutic effects in children with SE, but studies in adults have rarely been reported. In this paper, we review the efficacy and utility of KD in adult SE patients and highlight its application for clinical reference and management.

Abstract
OBJECTIVE To determine the factors affecting mortality and disability in status epilepticus (SE) and to evaluate the prediction ability of the Status Epilepticus Severity Score (STESS) for disability and mortality. MATERIALS AND METHOD The demographic and clinical characteristics, prognosis and prognosis predictors of 72 patients who were diagnosed with SE between 2013 and 2018 were retrospectively evaluated. The STESS was used to predict prognosis, and the modified Rankin scale (mRS) was used to determine the disability at discharge. RESULTS The study population had a mean age of 45.4 ± 20.7, and it was found that mortality was 22.2% and acute symptomatic etiology played a 54.1% role in etiology. Advanced age, refractory SE or super-refractory SE, acute symptomatic etiology, and a history of epilepsy were related to mortality, symptomatic etiology (acute, progressive, remote), a history of hospitalization and epilepsy in intensive care or in other departments other than the neurology department were associated with disability. The sensitivity of STESS in predicting mortality was 100%, specificity was 69%, accuracy was 76.4%, positive predictive value (PPV) was 48.5%, and the negative predictive value (NPV) was 100%. The sensitivity of STESS in predicting mobilization during discharge was 55.6% with a 63.9% specificity and 59.7% accuracy, PPV was 60.6%, and NPV was 59%. CONCLUSION It was observed that STESS strongly predicts a good prognosis; however, it was not found to be useful in predicting motor disability during discharge. Thus, new studies should be conducted to predict and evaluate mobility in SE patients at discharge.

Abstract
INTRODUCTION Status epilepticus (SE) is one of the most common medical emergencies, requiring urgent treatment; nearly 30 % patients develop refractory SE. The role of epilepsy surgery (ES) for refractory SE however remains unclear with empirical evidence limited to single case reports and small case series. The aim of the present study was to determine the clinical presentation, imaging characteristics and outcome of children with refractory SE who underwent emergency ES for refractory SE. MATERIAL AND METHOD Patients who had SE, failed to respond to escalating medical treatment of SE with/ without pharmacological suppression therapy, and eventually underwent ES were included. RESULTS There were ten children, 7 boys and 3 girls (range 6 months to 14 years). The age of onset of epilepsy varied from day 2 of life to 12.8 years. The duration of SE prior to surgery was 2-6 days (mean 3.7 days). Four patients had hemimegalencephaly, 3 had focal cortical dysplasia, 2 had Rasmussen's encephalitis, and one had hemispheric porencephalic cyst. The time interval between onset of seizures and ES ranged from 2 months to 8 years (mean 3.1 year). Seven patients underwent hemispherotomy, resection of dysplasia in two and temporo-parieto-occipital disconnection in one. Nine had Engel I outcome and Engel IIIa in one, at follow up of 12-44 months (mean 31 months). CONCLUSION Emergency ES is an effective treatment option for termination of refractory SE in children with structural pathology, after failure of medical treatment. Patients with refractory SE with focal or hemispheric structural abnormality on MRI, and concordant semiology with/without concordant EEG can be surgical candidates with or without invasive monitoring.

Abstract
AIM To describe the epidemiology and outcomes of convulsive status epilepticus (CSE) since the introduction of buccal midazolam and the change in International League Against Epilepsy definition of CSE to include seizures of at least 5 minutes. METHOD All children presenting to paediatric emergency departments with CSE (2011-2017) in Lothian, Scotland, were identified. Data, collated from electronic health records, included patient demographics, clinical characteristics, acute seizure management, and adverse outcomes (for example admission to intensive care). RESULTS Six hundred and sixty-five children were admitted with CSE who had 1228 seizure episodes (381 males, 284 females; median age 3y 8mo; age range 0-20y 11mo). CSE accounted for 0.38% (95% confidence interval 0.34-0.42) of annual attendances at emergency departments. Annual prevalence was 0.8 per 1000 children aged 0 to 14 years. Thirty-four per cent of children had recurrent CSE. Sixty-nine per cent of seizures lasted 5 to 29 minutes (median duration 10min). Buccal midazolam was given to 30% of children with CSE and had no effect on need for ventilatory support. Seventy per cent of children with CSE required hospital admission. Four per cent resulted in adverse outcome and there were only two deaths. Recurrent seizures, longer duration, and unprovoked seizures increased the odds of adverse outcome. INTERPRETATION Adverse outcomes have decreased and the use of buccal midazolam is promising. Identifying high-risk groups provides an opportunity for early intervention. These data form the basis for an extensive evaluation of acute seizure management and monitoring long-term outcomes. What this paper adds The annual prevalence of convulsive status epilepticus in Lothian, Scotland, was 0.8 per 1000 children. There was a decrease in case-fatality proportion from 3-9% to 0.2%. Use of buccal midazolam has increased, with no increase in adverse outcomes.

Abstract
PURPOSE Status epilepticus (SE) is associated with high morbidity and mortality. This multicenter retrospective cohort study aims to identify the factors associated with the occurrence of SE and the predictors of its recurrence in patients with adult-onset seizures. METHODS We retrospectively analyzed data of 1115 patients with seizure onset>18 years, observed from 1983 to 2020 in 7 Italian Centers (median follow-up 2.1 years). Data were collected from the databases of the Centers. Patients with SE were consecutively recruited, and patients without SE history were randomly selected in a 2:1 ratio. To assess determinants of SE, different clinical-demographic variables were evaluated and included in univariate and multivariate logistic regression model. RESULTS Three hundred forty-seven patients had a SE history, whereas the remaining 768 patients had either isolated seizures or epilepsy without SE history. The occurrence of SE was independently associated with increasing age at onset of disease (OR 1.02, 95% CI 1.01--1.03, p<0.001), female sex (OR 1.39, 95% CI 1.05--1.83, p=0.02) and known etiology (OR 3.58, 95% CI 2.61--4.93, p<0.001). SE recurred in 21% of patients with adult-onset SE and recurrence was associated with increasing number of anti-seizure medications taken at last follow-up (OR 1.88, 95% CI 1.31--2.71, p<0.001). CONCLUSIONS In patients with adult-onset seizures, SE occurrence is associated with known etiologies, advanced age and female sex. Patients with recurrent SE are likely to have a refractory epilepsy, deserving careful treatment to prevent potentially fatal events.

Abstract
Status epilepticus (SE) is a neurological and medical emergency, defined as a condition resulting either from the failure of the mechanisms responsible of seizure self-limitation or from the initiation of mechanisms which lead to atypically prolonged seizures. Further than death, SE can have long-term consequences, including neuronal injury, depending on the type, cause and duration of seizures with severe associated disabilities. In Europe, SE shows an incidence rate ranging about 9 to 40/100,000/y. In adults, mortality of patients with SE is ~30%, and even higher (up to 40%) in refractory status epilepticus. To date, etiology, duration, presence of comorbidity, level of consciousness, semiology and age are the main clinical predictors of SE outcome.

Abstract
BACKGROUND AND PURPOSE Status epilepticus is a neurologic emergency whose epidemiology, etiology and management are scarcely known in developing countries. Our objective was to describe the demographic and clinical features as well as the management of generalized convulsive status epilepticus (GCSE) in adult patients admitted to the emergency department of an academic hospital in Peru, between March 2019 and March 2020. METHODS Observational study of a prospective cohort in which patients were assessed by the emergency and neurology department on the first day of hospitalization, at discharge and at 30 days post-discharge in a follow-up visit. Relevant demographics and clinical data were collected. After being encoded and sorted, univariate statistical analysis was carried out. RESULTS Of the sample of 59 patients, 62.7% were males, 57.6% were unemployed, 89.8% did not finish high school, and 55.9% had intermittent GCSE with no seizure at arrival. The total calculated median times were: 60 minutes from GCSE onset to hospital arrival, 110 minutes from GCSE onset to 1st line therapy, and 7 minutes from hospital arrival to 1st line therapy. The most frequently used antiepileptic drugs were one dose of benzodiazepine (41.7%), phenytoin (76.9%), and additional doses of benzodiazepines (60%) for 1st, 2nd, and 3rd line therapies, respectively. The most frequent etiologies were antiepileptic drug suspension (27.1%), undetermined (25.4%) and acute stroke (11.8%). 62.71% had 0-2 modified Rankin score at discharge. CONCLUSIONS In this cohort of patients, GCSE was mainly intermittent. Management times differed from the guidelines' recommendations.

Abstract
Context Refractory status epilepticus (RSE) and super-refractory status epilepticus (SRSE) are neurological emergencies with considerable mortality and morbidity. In this paper, we provide an overview of causes, evaluation, treatment, and consequences of RSE and SRSE, reflecting the lack of high-quality evidence to inform therapeutic approach. Sources This is a narrative review based on personal practice and experience. Nevertheless, we searched MEDLINE (using PubMed and OvidSP vendors) and Cochrane central register of controlled trials, using appropriate keywords to incorporate recent evidence. Results Refractory status epilepticus is commonly defined as an acute convulsive seizure that fails to respond to two or more anti-seizure medications including at least one nonbenzodiazepine drug. Super-refractory status epilepticus is a status epilepticus that continues for ≥24 hours despite anesthetic treatment, or recurs on an attempted wean of the anesthetic regimen. Both can occur in patients known to have epilepsy or de novo, with increasing recognition of autoimmune and genetic causes. Electroencephalography monitoring is essential to monitor treatment response in refractory/super-refractory status epilepticus, and to diagnose non-convulsive status epilepticus. The mainstay of treatment for these disorders includes anesthetic infusions, primarily midazolam, ketamine, and pentobarbital. Dietary, immunological, and surgical treatments are viable in selected patients. Management is challenging due to multiple acute complications and long-term adverse consequences. Conclusions We have provided a synopsis of best practices for diagnosis and management of refractory/superrefractory status epilepticus and highlighted the lack of sufficient high-quality evidence to drive decision making, ending with a brief foray into avenues for future research.

Abstract
Status epilepticus (SE) is associated with high mortality and morbidity. Although SE is frequently seen in elderly patients, there is a lack of a cohesive report of outcome measures and associated factors within this population. Our aim was to systematically review studies reporting outcomes of SE among elderly patients and factors influencing these outcomes. A literature search was conducted in PubMed/MEDLINE, EMBASE, CINAHL Complete, and Cochrane Library from database conception to April 22, 2018. A total of 85 studies were included in this systematic review. The included studies show that mortality is higher in elderly patients than in adult patients. Lesional etiologies, higher number of comorbidities, NCSE, RSE, longer hospital and intensive care unit stays, and infection during hospitalization are associated with poor outcome. Future studies should consider measuring functional outcomes, comparative studies between elderly and adults and AED clinical trials specific for elderly with SE.

Abstract
Status epilepticus (SE) is a neurologic emergency with high morbidity and mortality. The assessment of a patient's prognosis is crucial in making treatment decisions. In this review, we discuss various markers that have been used to prognosticate SE in terms of recurrence, mortality, and functional outcome. These markers include demographic, clinical, electrophysiological, biochemical, and structural data. The heterogeneity of SE etiology and semiology renders development of prognostic markers challenging. Currently, prognostication in SE is limited to a few clinical scores. Future research should integrate clinical, genetic and epigenetic, metabolic, inflammatory, and structural biomarkers into prognostication models to approach "personalized medicine" in prognostication of outcomes after SE.

Abstract
PURPOSE To evaluate barbiturate anaesthetic therapy using thiamylal for febrile refractory status epilepticus (fRSE) in children. METHODS This was a review of a prospectively-collected database between April 2012-March 2016 for fRSE cases treated with thiamylal anaesthetic therapy in a single paediatric hospital in Japan. The sample comprised 23 children (median age, 23 months) with fRSE that underwent thiamylal anaesthetic therapy for convulsive seizures lasting longer than 60 min, sustained after intravenous administration of benzodiazepine and non-benzodiazepine anticonvulsants. The intervention comprised protocol-based thiamylal anaesthetic therapy with bolus administration. We measured the dose and time required to achieve the burst suppression pattern (BSP) on electroencephalography, seizure recurrence, death, neurological sequelae, and complications. RESULTS All patients except one reached the BSP. The thiamylal median dose until reaching the BSP was 27.5 mg/kg, and the median time from thiamylal administration to reaching the BSP was 109.5 min. There was one case of immediate treatment failure and one of withdrawal seizure, but no breakthrough seizure. No deaths occurred during treatment, and neurological sequelae occurred in four cases (17%). Vasopressors were administered in all cases. Other complications included 11 cases of pneumonia and one of enterocolitis. CONCLUSION We revealed the time and dose required to reach the BSP with thiamylal anaesthetic therapy using bolus administration in children. Our results suggested that reaching the BSP with bolus administration requires markedly less time than without bolus administration, rarely causes seizure recurrence in paediatric fRSE, and causes haemodynamic dysfunction and infections as often as observed without bolus administration.

Abstract
The aim of this study was to study the predisposing factors and prognosis of status epilepticus (SE) in patients with autoimmune encephalitis (AE).A total of 227 cases of AE were collected from the inpatient department of West China Hospital of Sichuan University from January 2010 to May 2018. All patients met the 2015 criteria for the diagnosis of AE. The binary logistic regression model was used to multivariate and retrospective chart analysis the predisposition factors for SE and its prognostic factors.Of the 227 patients with AE, 50 (22.03%) had SE during hospitalization, and 19 patients with SE had a poor prognosis (modified Rankin score MRS = 3-6), and 7 patients with no SE had a poor prognosis. In the logistic regression model, electroencephalograms (EEGs) abnormalities (P = .000) and head magnetic resonance imaging (MRI) abnormalities (P = .003) were associated with a predisposition to SE, while Glasgow scores <8 (P = .027), abnormal EEG (P = .046), delayed immunotherapy (P = .012), and SE duration at admission lasting >30 minutes (P = .023) were risk factors for a poor prognosis of SE.SE is a common complication in patients with AE. EEG and MRI abnormalities may be predisposing factors for SE. Glasgow scores <8 points, abnormal EEG, delayed immunotherapy, and SE duration lasting >30 minutes at admission are risk factors for a poor prognosis in patients with SE.

Abstract
Status epilepticus (SE) is a life-threatening condition needing immediate care to prevent brain damage. SE with electrographic and behavioral features similar to those seen in humans is reproduced in rodents by i.p. pilocarpine injection, and can be terminated by diazepam and ketamine treatment but only behaviourally, not electrographically. Little is known on the behavioral and EEG effects induced by a delayed administration of ketamine (25 mg/kg) after diazepam (10 mg/kg) or vice versa. Therefore, we analysed behavior and EEG activity recorded from the mouse hippocampal CA3 region before, during SE and after anticonvulsant treatments. In the first group (n = 4), diazepam was administered one hour before ketamine whereas in the second group (n = 4) ketamine was administered one hour before diazepam. The EEG SE did not disappear after each of the two treatments but progressed within 4 h to a pattern of interictal discharges. However, diazepam administration before ketamine significantly shortened the time of behavioral recovery compared to when ketamine was administered before diazepam (p < 0.05). The two protocols were also associated to distinct EEG changes in gamma and high frequency oscillations. In conclusion, although diazepam and ketamine are not effective in stopping EEG SE, diazepam administration one hour before ketamine shortens behavioral recovery in pilocarpine-treated mice.

Abstract
Importance Treatment delay for seizures can lead to longer seizure duration. Whether treatment delay is associated with major adverse outcomes, such as death, remains unknown. Objective To evaluate whether untimely first-line benzodiazepine treatment is associated with unfavorable short-term outcomes. Design, Setting, and Participants This multicenter, observational, prospective cohort study included 218 pediatric patients admitted between June 1, 2011, and July 7, 2016, into the 11 tertiary hospitals in the United States within the Pediatric Status Epilepticus Research Group. Patients, ranging in age from 1 month to 21 years, with refractory convulsive status epilepticus (RCSE) that did not stop after the administration of at least 2 antiseizure medications were included. Patients were divided into 2 cohorts: those who received the first-line benzodiazepine treatment in less than 10 minutes and those who received it 10 or more minutes after seizure onset (untimely). Data were collected and analyzed from June 1, 2011, to July 7, 2016. Main Outcomes and Measures The primary outcome was death during the related hospital admission. The secondary outcome was the need for continuous infusion for seizure termination. Multivariate analysis of mortality controlled for structural cause, febrile RCSE, age, and previous neurological history (including previous RCSE events). Use of continuous infusions was additionally adjusted for generalized RCSE, continuous RCSE, and 5 or more administrations of antiseizure medication. Results A total of 218 patients were included, among whom 116 (53.2%) were male and the median (interquartile range) age was 4.0 (1.2-9.6) years. The RCSE started in the prehospital setting for 139 patients (63.8%). Seventy-four patients (33.9%) received their first-line benzodiazepine treatment in less than 10 minutes, and 144 (66.1%) received untimely first-line benzodiazepine treatment. Multivariate analysis showed that patients who received untimely first-line benzodiazepine treatment had higher odds of death (adjusted odds ratio [AOR], 11.0; 95% CI, 1.43 to ∞; P = .02), had greater odds of receiving continuous infusion (AOR, 1.8; 95% CI, 1.01-3.36; P = .047), had longer convulsive seizure duration (AOR, 2.6; 95% CI, 1.38-4.88; P = .003), and had more frequent hypotension (AOR 2.3; 95% CI, 1.16-4.63; P = .02). In addition, the timing of the first-line benzodiazepine treatment was correlated with the timing of the second-line (95% CI, 0.64-0.95; P < .001) and third-line antiseizure medications (95% CI, 0.25-0.78; P < .001). Conclusions and Relevance Among pediatric patients with RCSE, an untimely first-line benzodiazepine treatment is independently associated with a higher frequency of death, use of continuous infusions, longer convulsion duration, and more frequent hypotension. Results of this study raise the question as to whether poor outcomes could, in part, be prevented by earlier administration of treatment.

Abstract
RATIONALE Refractory status epilepticus (RSE) is the persistence of status epilepticus despite second-line treatment. Super-refractory SE (SRSE) is characterized by ongoing status despite 48 h of anaesthetic treatment. Due to the high case fatality in RSE of 16-39%, off label treatments without strong evidence of efficacy in RSE are often administered. In single case-reports and small case series totalling 28 patients, acute implantation of VNS in RSE was associated with 76% and 26% success rate in generalized and focal RSE respectively. We performed an updated systematic review of the literature on efficacy of VNS in RSE/SRSE by including all reported patients. METHODS We systematically searched EMBASE, CENTRAL, Opengre.eu, and ClinicalTrials.gov, and PubMed databases to identify studies reporting the use of VNS for RSE and/or SRSE. We also searched conference abstracts from AES and ILAE meetings. RESULTS 45 patients were identified in total of which 38 were acute implantations of VNS in RSE/SRSE. Five cases had VNS implantation for epilepsia partialis continua, one for refractory electrical status epilepticus in sleep and one for acute encephalitis with refractory repetitive focal seizures. Acute VNS implantation was associated with cessation of RSE/SRSE in 74% (28/38) of acute cases. Cessation did not occur in 18% (7/38) of cases and four deaths were reported (11%); all of them due to the underlying disease and unlikely related to VNS implantation. Median duration of the RSE/SRSE episode pre and post VNS implantation was 18 days (range: 3-1680 days) and 8 days (range: 3-84 days) respectively. Positive outcomes occurred in 82% (31/38) of cases. CONCLUSION VNS can interrupt RSE and SRSE in 74% of patients; data originate from reported studies classified as level IV and the risk for reporting bias is high. Further prospective studies are warranted to investigate acute VNS in RSE and SRSE.

Abstract
PURPOSE This randomized control study was conducted to compare the efficacy of sodium valproate (SVP) and levetiracetam (LEV) following initial intravenous lorazepam in elderly patients (age: >60years) with generalized convulsive status epilepticus (GCSE) and to identify predictors of poor seizure control. METHODS A total of 118 patients (mean age: 67.5 ± 7.5 years, M:F = 1.6:1), who had presented with GCSE were randomized into the SVP or LEV treatment arms. All patients received initial intravenous lorazepam (0.1 mg/kg) followed by one of the two antiepileptic drugs (AEDs), parenteral SVP (20-25 mg/kg) or LEV (20-25 mg/kg). Those who failed to achieve control with the initial AED, were crossed over to receive the other AED. One-hundred patients (SVP = 50; LEV = 50) completed the study. RESULTS SE could be controlled with lorazepam and one of the AEDs (SVP or LEV) in 71.18% (84/118). Intention-to-treat analysis showed that the two groups did not differ significantly in terms of seizure control [SVP: 41/60 (68.3%); LEV: 43/58 (74.1%), p = 0.486]. Of 100 patients who completed the study, seizure control was achieved in 38/50(76%) in the SVP and 43/50(86%) in the LEV group (p = 0.202). After crossing over to the second AED, SE could be controlled in an additional in 50% (6/12) in SVP (+LEV) group and in 14.3% (1/7) in LEV (+SVP) group. Overall, after the second AED, seizure control was achieved in 77.1% (91/118). Higher STESS was associated with poor therapeutic response (p = 0.049). CONCLUSIONS The efficacy of SVP and LEV following initial lorazepam in controlling GCSE in elderly population was comparable, hence the choice of AED could be individualized.

Abstract
AIM Aetiologies of first-ever convulsive seizures may be diverse, not all leading to recurrence or epilepsy diagnosis. We aimed to describe the epidemiology of first-ever convulsive seizures in children, investigating risk factors for recurrence and epilepsy diagnosis. METHOD This was a retrospective study of children presenting with a first-ever convulsive seizure to a tertiary-care paediatric emergency department (PED) in Italy, in a 12-month period (2011-2012). RESULTS One hundred and eight children (57 males, 51 females) presented to the PED for a first-ever convulsive seizure; 90.7% were 6 months to 6 years old (median age 1y 10mo, mean 2y 7mo, range 0mo-14y 4mo). Seizure duration was less than 5 minutes in 76.8%. Seizures were 'unprovoked' in 19.4% and 'provoked' in 80.6%. At 4-year follow-up, 37.9% of patients experienced recurrence and 13.6% received a diagnosis of epilepsy. Factors significantly associated with recurrence were the 'unprovoked' nature of the first seizure, multiple seizures in the first 24 hours, positive family history of febrile seizures or epilepsy, and pre-existing neurological conditions/problems. Factors significantly associated with a diagnosis of epilepsy were the 'unprovoked' nature of the first seizure, age older than 6 years, pre-existing neurological conditions/problems, and focal onset of first seizure. INTERPRETATION Children presenting to the PED with first-ever convulsive seizures represent a heterogeneous group. The identification of prognostic factors for recurrence and epilepsy diagnosis may help provide tailored counselling and follow-up. WHAT THIS PAPER ADDS Seizures were 'unprovoked' in 19.4% and 'provoked' in 80.6% of children presenting to the emergency department. At 4-year follow-up, 37.9% relapsed, and 13.6% received a diagnosis of epilepsy. 'Unprovoked' first seizure, family history of febrile seizures, and pre-existing neurological conditions were associated with recurrence. 'Unprovoked' first seizure, age younger than 6 years, and pre-existing neurological conditions were associated with epilepsy diagnosis.

Abstract
AIM To study the postictal changes in the autonomic regulation of the heart rhythm and its functional capabilities in different periods after epistatus and to assess the risk of life-threatening arrhythmias. MATERIAL AND METHODS The study was conducted on Wistar rats after epileptic status (ES). Telemonitoring of EEG and ECG was performed in the online mode using the system of the company 'ADInstruments'. Functional stress test with dobutamine was used. RESULTS ES leads to a long-lasting disturbance of autonomic regulation (AR) of the heart and reduces its functional capabilities. The heart's AR balance is shifted towards sympathetic tonus 5 days after ES. This increases the predictors of life-threatening arrhythmias. The decrease in SWD activity increases the activity of parasympathetic tonus 10 days after ES. However, this is due to the tension of regulation mechanisms and the risk of life-threatening arrhythmias. CONCLUSION The high degree of seizure activity of the brain in the ES predetermines prolonged postictal disorders of the AR heart, which reduce its functional capabilities and increase the risk of life-threatening arrhythmias.

Abstract
AIM To determine the clinical profile, etiologies and predictors of mortality in patients with convulsive status epilepticus (CSE) among rural population of North India in view of limited published data on epidemiology and etiology of status epilepticus (SE) from developing countries. METHODS One hundred sixty-two consecutive adult patients with CSE were evaluated from 2016 to 2018 for demographic profile, etiologies and predictors of poor outcome. RESULTS The mean age was 41.71 ± 19.72 years. Most of the CSE cases were acute symptomatic (48.8%) type with central nervous system (CNS) infections (24.1%) being the predominant precipitating factor. Antiepileptic drugs (AEDs) noncompliance accounted for 34.9% of the cases with pre-existing epilepsy. The median duration of CSE was 5.5 h (IQR-3-10 h). 82.1% cases responded to the first line drugs and their response was related with duration of CSE (p = .0045). Case fatality was 16.0% and the predictors of the mortality were; low Glasgow Coma Scale (GCS) (OR =9.64, 95% CI= 2.064-45.02; p = .0001), lack of response to first line drugs (OR =0.019, 95% CI= 0.003-0.11; p = .0001) and absence of past history of epilepsy (OR =0.525, 95%CI =0.104-2.66; p = .004). CONCLUSIONS CNS infection and AEDs noncompliance were identified to be the major cause of CSE which can be potentially preventable. Present study signifies that prompt and successful control of infections appears to be the most efficient preventive approach. Level of consciousness as a potential predictor of poor outcome can be quickly accessible to the treating clinician in optimizing treatment strategies.

[PMID: 30528098 DOI: 10.1016/j.seizure.2018.09.011] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 09/11/2018] [Accepted: 09/14/2018] [Indexed: 01/10/2023] Open
Abstract
PURPOSE To summarize the use of continuous electroencephalographic monitoring (cEEG) in the diagnosis and management of pediatric convulsive status epilepticus (CSE) and subsequent non-convulsive seizures (NCS) with a focus on available guidelines and infrastructure. In addition, we provide an overview of quantitative EEG (QEEG) for the identification of NCS in critically ill children. METHODS We performed a review of the medical literature on the use of cEEG and QEEG in pediatric CSE. This included published guideline, consensus statements, and literature focused on the use of cEEG and QEEG to detect NCS. RESULTS cEEG monitoring is recommended for prompt recognition of ongoing seizures that may be subtle, masked by pharmacologic paralysis, and or converted from convulsive seizures to NCS after administration of anti-seizure medications. Evidence indicating that high seizure burden is associated with worse outcome has motivated prompt recognition and management of NCS. The American Clinical Neurophysiology Society's consensus statement recommends a minimum of 24 h to exclude electrographic seizures, while the Neurocritical Care Society's guideline suggests 48 h in patients that are comatose. The use of QEEG amongst electroencephalographers and critical care medicine providers is increasing for NCS detection in critically ill children. The sensitivity and specificity of QEEG to detect NCS ranges from 65 to 83% and 65-92%, respectively. CONCLUSION The use of cEEG is important to the diagnosis and treatment of NCS or subtle clinical seizures after pediatric CSE. QEEG allows cEEG data to be reviewed and interpreted quickly and is a useful tool for detection of NCS after CSE.

Chronic Skull Base Erosion from Temporomandibular Joint Disease Causes Generalized Seizure and Profound Lactic Acidosis. Case Rep Crit Care 2018; 2018:8795036. [PMID: 30363607 PMCID: PMC6180988 DOI: 10.1155/2018/8795036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Accepted: 09/06/2018] [Indexed: 11/18/2022] Open
Abstract
This report displays a rare presentation of lactic acidosis in the setting of status epilepticus (SE). The differential diagnosis of lactic acidosis is broad and typically originates from states of shock; however, this report highlights an alternative and rare etiology, SE, due to chronic skull base erosion from temporomandibular joint (TMJ) disease. Lactic acidosis is defined by a pH below 7.35 in the setting of lactate values greater than 5 mmol/L. Two broad classifications of lactic acidosis exist: a type A lactic acidosis which stems from global or localized tissue hypoxia or a type B lactic acidosis which occurs once mitochondrial oxidative capacity is unable to match glucose metabolism. SE is an example of a type A lactic acidosis in which oxygen delivery is unable to meet increased cellular energy requirements. This report is consistent with a prior case series that consists of five patients experiencing generalized tonic-clonic (GTC) seizures and lactic acidosis. These patients presented with a pH range of 6.8-7.41 and lactate range of 3.8-22.4 mmol/L. Although severe lactic acidosis following GTC has been described, this is the first report in the literature of chronic skull base erosion from TMJ disease causing SE.

Perampanel in the treatment of status epilepticus: A systematic review of the literature. Epilepsy Behav 2018; 86:179-186. [PMID: 30076046 DOI: 10.1016/j.yebeh.2018.07.004] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2018] [Revised: 07/03/2018] [Accepted: 07/04/2018] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Perampanel (PER) is a noncompetitive β-amino-3-(5-methyl-3-oxo-1,2-oxazol-4-yl)propionic acid (AMPA) receptor antagonist with demonstrated efficacy in animal models of status epilepticus (SE). We performed a systematic review of the literature to assess the efficacy and tolerability of PER in the treatment of refractory and super-refractory SE. METHODS We searched Medline, Embase, and CENTRAL (accessed from inception to April 30, 2018) to identify studies evaluating oral PER as treatment of SE of any type. We also searched the OpenGrey repository and conference proceedings of international congresses by the International League Against Epilepsy and by the American Epilepsy Society from 2012 onwards. RESULTS Ten articles were included, with a total of 69 episodes of SE occurring in 68 patients (aged 18 to 91 years). The type and etiology of SE varied remarkably across studies. The number of drugs used prior to PER ranged from 1 to 9. The time from SE onset to PER administration ranged from 9.25 h to 35 days. The initial PER dose ranged from 2 to 32 mg. The proportion of patients achieving clinical SE cessation varied from 17% to 100%. The time from PER administration to SE cessation ranged from 1 h to 4 weeks. CONCLUSIONS The currently available evidence supporting the use of PER in SE is weak and hampered by several confounding factors. Further studies should be performed in more clinically homogeneous and larger cohorts to evaluate the efficacy and safety of PER administered in earlier stages of SE, at higher dosages, and at intervals shorter than 24 h.

[PMID: 29778845 DOI: 10.1016/j.yebeh.2018.04.027] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2018] [Revised: 04/26/2018] [Accepted: 04/28/2018] [Indexed: 11/15/2022]
Abstract
BACKGROUND There were several studies that have reported on the long-term mortality rate of status epilepticus (SE). However, these studies were conducted mainly in Western countries using small study populations. This study aimed to evaluate predictors for long-term mortality in SE using the Thai national healthcare database. METHODS This study was conducted using the Thai national Universal Health Coverage (UC) database. The eligibility criteria for this study were that all patients were diagnosed with SE and had been admitted to any hospital between 2005 and 2015. Mortality was defined at discharge and at one, three, five, and 10 years. All eligible patients were categorized as either having survived or having died. The mortality rates were calculated at one, three, five, and 10 years. Factors associated with mortality were analyzed using backward multivariate Cox proportional hazard regression analysis. Kaplan-Meier was performed to estimate the survival rate. RESULTS During the study period, there were 21,732 patients with SE admitted who met the study criteria. The total observation time was 85,821.28 person-years. Of the patients enrolled, 3642 (or 4.24 per 100 person-years [95% confidence interval (CI): 4.11-4.38]) died. Factors positively associated with mortality in patients with SE were central nervous system (CNS) infection, cancer, heart diseases, chronic renal failure, septicemia, pneumonia, respiratory failure, acute renal failure, and shock. Heart diseases had the highest adjusted hazard ratio at 2.69 (95% CI: 2.47-2.93). Two factors were negatively related with SE mortality: hypertension and urinary tract infection. CONCLUSION Long-term mortality in patients with SE had both positive and negative predictors in the national database.

Abstract
BACKGROUND Adequate identification of the severity of status epilepticus (SE) contributes to individualized treatment. The scales most widely used for this purpose are: Status Epilepticus Severity Score (STESS), Epidemiology-Based Mortality Score in Status Epilepticus (EMSE) and modified Rankin Scale STESS (mRSTESS). The aim of this study was to evaluate the performance of the STESS, EMSE and mRSTESS scales to predict high disability and hospital mortality at discharge (HD/HM). METHODS A prospective study was conducted in which total of 41 patients were registered from November 2015 to January 2018 at Eugenio Espejo Hospital. Clinical variables such as age, sex, clinical status at the beginning of the SE, initial symptom of SE, as well as the STESS, mRSTESS and EMSE variant scales were studied at the time of the diagnosis of SE. RESULTS A total of 41 patients were evaluated, of which 8 (19.5%) had HD at hospital discharge and died 13 (31.7%) during their care. The area under the receiver operating characteristic curve to predict HD/HM was 0.71 (95% CI (confidence interval) 0.55-0.87), 0.81 (95% CI 0.67-0.94), 0.89 (95% CI 0.79-0.99), 0.90 (95% CI 0.80-1.0), 0.89 (95% CI 0.78-0.99) for the STESS, mRSTESS, EMSE-EAC (etiology, age, comorbidities), EMSE-EACEG (etiology, age, comorbidities, electroencephalography) and EMSE-ECLEG (etiology, age, level of consciousness at pre-treatment, electroencephalography), variants of EMSE, respectively. The binary logistic regression demonstrated how the following cut-off points were determined: STESS OR (odd ratio) 4.80 (p = 0.02), mRSTESS OR 7.89 (p = 0.00), EMSE-EAC OR 22.16 (p = 0.00), EMSE-ECLEG OR 18.00 (p = 0.00), EMSE-EACEG OR 14 (p = 0.00). CONCLUSIONS All of the evaluated scales (STESS, mRSTESS, and EMSE) were shown to be useful in predicting HD/HM. EMSE was observed to be the most effective of the scales, with relative similarities among the variants.
