Abstract
OBJECTIVES To investigate the electroencephalogram (EEG) characteristics and progression of febrile infection-related epilepsy syndrome (FIRES) in children, aiming to enhance diagnosis and treatment approaches. METHODS A retrospective analysis was conducted on 26 children with FIRES between May 2017 and December 2021. RESULTS All 26 children (100%) presented with fever at the onset, followed by frequent convulsions that rapidly progressed into convulsive status. Ventilator support was required for 22 cases (85%). During the acute phase, EEG features demonstrated the disappearance of background activity and physiological sleep cycles in all children. Diffuse slow waves and multifocal slow spike slow waves were observed as abnormal waves during the interictal period. A characteristic pattern of focal low amplitude fast wave initiation was detected in all children during seizure episodes. In the chronic phase, the background EEG activity gradually recovered, and the presence of abnormal waves was relatively limited. The characteristic pattern of focal slow wave rhythm initiation was evident during seizure episodes. Additionally, extreme δ brushes were observed in four cases (15%). CONCLUSIONS These findings suggest that EEG manifestations in children with FIRES exhibit distinctive patterns during the acute and chronic stages, providing significant value for early diagnosis and clinical staging. Extreme δ brushes may be one of the distinctive markers of children with FIRES.

Abstract
BACKGROUND Febrile infection-related epilepsy syndrome (FIRES) is a rare and catastrophic clinical syndrome occurring in previously healthy patients. Aetiology is still unknown and outcome usually poor. We describe a case of myoclonic prolonged super refractory status epilepticus (P-SRSE) in FIRES in a patient admitted to the paediatric intensive care unit of Padova, Italy. CASE REPORT A previously healthy 14-year-old girl with onset of myoclonic status epilepticus after a mild febrile illness was admitted to our hospital with a diagnosis of FIRES. Extensive diagnostic work-up was inconclusive. Status epilepticus and electroclinical seizures recurred every time weaning from anaesthetic agents was attempted. Eventually, a vagal nerve stimulator (VNS) was implanted and cannabidiol (CBD) administered, 43 days and 70 days after P-SRSE onset, respectively. Two days after CBD introduction, status epilepticus weaned and the girl rapidly regained complete consciousness showing a brilliant and unexpected recovery. At last follow-up, 12 months later, she is 8-months seizure free on multiple antiseizure medications, has only mild neuropsychological impairment with no neurological and intellective deficit. CONCLUSIONS To our knowledge, this represents a unique case with an extremely favourable evolution with a possible effect of the association of VNS and CBD to traditional antiseizure medications.

Abstract
Awareness of the long-term outcomes of status epilepticus is key to understanding the condition overall. Maintaining ties with patients' families is vital to both obtaining better long-term patient outcomes and obtaining that elusive data on long-term conditions. Common language and linked infrastructure support these ties. This position is posed within the context of NORSE (new-onset refractory status epilepticus) and FIRES (febrile infection-related epilepsy syndrome). This paper was presented at the 8th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures held in September 2022.

Abstract
Little is known of the etiology, course, and treatment of new-onset refractory status epilepticus (NORSE) in children. Here we identified etiologies, electroencephalography (EEG) characteristics, and neuroimaging findings among pediatric patients with NORSE and among two patient subgroups, febrile infection-related epilepsy syndrome (FIRES) group and non-FIRES group. We also examined treatments and risk factors related to poor prognosis. Ninety-two children with NORSE were identified in Children's Hospital of Chongqing Medical University between January 1, 2010 and September 1, 2020. The end date was chosen to guarantee at least a 6-month follow-up. Our results indicated that patients with FIRES account for 90% of pediatric patients with NORSE. The clinical, EEG, and neuroimaging results and prognosis were not significantly different between the FIRES group and non-FIRES group of individuals. 68.5% of our patients had unknown etiology, and viral etiology was the most common identified cause (26.1%). Electroencephalography might have a certain diagnostic value for NORSE. A gradual increase in seizure burden was obvious from the onset of disease, and continuous or recurrent ictal discharge lasting ≥ 30 min was quite common in our study. The mortality was 22.8% in our study. Among the 71 surviving patients, the outcome at discharge was poor but improved during follow-up, and 68.5% had good or fair outcomes at their last follow-up. A poor outcome was observed in 39 of 92 cases (42%), with 43.9% and 30% of individuals in the FIRES group and non-FIRES group, respectively, having a poor outcome. The presence of super refractory status epilepticus (SRSE), electrographic seizures and nonconvulsive status epilepticus (NCSE), and diffuse cortical edema and multifocal abnormality may be related to a poor prognosis. Our analysis did not indicate that prognosis was directly related to etiology or treatment. Management of NORSE is challenging, and the role of immunotherapy warrants further investigation.

Abstract
OBJECTIVE This study aims to retrospectively evaluate the long-term efficacy, tolerability, and safety of therapeutic plasma exchange (TPE) in children with various neuroimmunological disorders. METHODS This analysis was a single-center, retrospective cohort study of pediatric patients with neuroimmunological events undergoing TPE procedures in a tertiary referral center. RESULTS There were 23 patients, 14 boys (60.9%), aged at diagnosis onset 8 months to 16.8 years. The main indications of TPE were Guillain-Barré syndrome (GBS, n = 8), autoimmune encephalitis (n = 5), febrile infection-related epilepsy syndrome (FIRES, n = 4), and acute disseminated encephalomyelitis (ADEM, n = 3). There was no life-threatening complication due to the TPE procedures. Eight (34.8%) of 23 patients experienced 13 (7%) complications in 186 TPE procedures, mostly electrolyte disturbances (n = 5). None of patients discontinued TPE due to complications. Two (8.7%) of 23 patients had marked improvement, 6 (26.1%) had moderate and 11 (47.8%) had mild improvement after TPE. The last follow-up visit revealed neurological sequelae in 12 (52.2%) patients. Therapeutic plasma exchange was found to be more effective on GBS, autoimmune encephalitis and myasthenia gravis, less effective on ADEM and FIRES. There was no correlation between improvement with TPE and clinical parameters, including age, sex, diagnosis, disease duration before TPE, presence of intubation, and length of stay in the intensive care unit and hospital. CONCLUSION Therapeutic plasma exchange was found to be effective and well-tolerated in children with various types of neuroimmunological disorder, with at least mild improvement in approximately 80% of the patients and no life-threatening complications.

Abstract
This special issue of the Biomedical Journal is entirely dedicated to the latest updates regarding the medical efforts to preserve the fragile young brain after injury. Thereby, we learn about symptoms and diseases such as different forms of epilepsy, acute encephalopathy, increased intracranial pressure, and posthaemorrhagic hydrocephalus, as well as about their origins, such as infection, autoimmune diseases, preterm birth, or abusive head trauma. Moreover, diagnosis and surveillance techniques are discussed, including ultrasound of the optic nerve sheath diameter and multimodal monitoring. Finally, we discover various established and emerging therapeutic approaches, comprising target temperature management, ketogenic diet, and immunomodulation.

Abstract
BACKGROUND To compare the clinical characteristics and outcomes of pediatric patients with refractory status epilepticus (RSE) and super-refractory status epilepticus (SRSE) who received therapeutic hypothermia (TH) plus anticonvulsants or anticonvulsants alone. METHODS Two-medical referral centers, retrospective cohort study. Pediatric Intensive Care Unit (PICU) at Taoyuan Chang Gung Children's hospital and Kaohsiung Chang Gung Memorial Hospital. We reviewed the medical records of 23 patients with RSE/SRSE who were admitted to PICU from January 2014 to December 2017. Of these, 11 patients received TH (TH group) and 12 patients did not (control group). RESULTS The selective endpoints were RSE/SRSE duration, length of PICU stay, and Glasgow Outcome Scale (GOS) score. We applied TH using the Artic Sun® temperature management system (target temperature, 34-35 °C; duration, 48-72 h). Of the 11 patients who received TH, 7 had febrile infection-related epilepsy syndrome (FIRSE), one had Dravet syndrome, and three had traumatic brain injury. The TH group had significantly shortern seizure durations than did the control group (hrs; median (IQR) 24(40) vs. 96(90), p < 0.05). Two patients in the TH group died of pulmonary embolism and extreme brain edema. The length of PICU stay was similar between the groups (days; median (IQR) 30(42) v.s 30.5(30.25)). The TH group had significantly better long-term outcomes than did the control group (GOS score, median (IQR) 4(2) v.s 3 (0.75), p = 0.01∗). The TH group had a significantly lower incidence of later chronic refractory epilepsy than did the control group (TH v.s non-TH, 5/11 (45%) v.s. 12/12(100%), p < 0.01). CONCLUSIONS TH effectively reduced the seizure burden in patients with RSE/SRSE. Our findings support that for patients with RSE/SRSE, TH shortens the seizure duration, ultimately reducing the occurrence of post-status epilepticus epilepsy and improving patients' long-term survival.

Abstract
BACKGROUND The febrile infection-related epilepsy syndrome (FIRES) is a catastrophic epileptic encephalopathy which developed the refractory status epilepticus following or during a nonspecific febrile illness. To analyze the short-term and long-term outcome of FIRES in the children, we retrospectively analyzed the related data. METHODS The motor outcome was evaluated by modified Rankin scale (mRS). Poor motor outcome was defined as a mRS score of 4 or higher at discharge. Significant motor decline was defined as the mRS difference more than 2 before hospital admission and at discharge. RESULTS We totally enrolled 25 patients for analysis. Four patients were expired during hospitalization, and one patient was lost to follow-up after discharge. Therefore, a total 20 patients were finally analyzed. The age of disease onset ranged from 1.6 to 17.2 years (mean: 9.6 ± 4.4 years). Newly acquired epilepsy and cognitive deficit occurred in 100% and 61%, respectively. The duration of the anesthetic agents ranged from 7 to 149 days (mean: 34.2 ± 36.1 days). The duration of anesthetic agent usage (p = 0.011), refractory epilepsy (p = 0.003), and the use of ketogenic diet (p = 0.004) were significantly associated with the poor long-term motor outcome, and the number of anesthetic agents tended to be associated with the poor long-term motor outcome (p = 0.050). In-hospital mortality was 16%. Significant functional decline at discharge occurred in 100%. However, there was improvement in long-term follow-up. CONCLUSION The outcome of FIRES is poor with significant mortality and morbidities. Refractory epilepsy with cognitive deficit in survived cases is common, but improvement is possible.

Abstract
Purpose This report sheds light on a successful treatment in febrile infection-related epilepsy syndrome (FIRES) with the combined use of lidocaine and MgSO4. Methods We report a 12-year-old previously healthy girl who experienced an upper respiratory infection with fever and headache for 2 days, then suddenly went into a coma followed by repetitive status epilepticus. All tests for CNS infection, metabolic and toxic diseases, and autoimmune encephalitis were negative. Hence, the diagnosis of FIRES was made. During 5 weeks of hospital treatment, various antiepileptic drugs were administered at different times without success. To achieve seizure control, we then attempted the use of lidocaine first, then followed by MgSO4. Results The SE was successfully controlled when lidocaine plus MgSO4 was introduced. At follow-up, almost no neurological sequelae remained. Conclusion This is the first report describing the combined use of lidocaine and MgSO4 with successful treatment outcomes. This experience has indicated that even FIRES can be controlled if treated promptly with certain agents. However, more studies are needed to explore the mechanisms and effects of lidocaine and MgSO4 in FIRES.

Abstract
AIM To clarify the effect of levetiracetam (LEV) for acute and chronic seizure control in acute encephalitis with refractory, repetitive partial seizures (AERRPS). METHODS We retrospectively reviewed the clinical course of six AERRPS cases treated with LEV, and explored the acute phase termination by withdrawal from barbiturate-induced coma under artificial ventilation, and the reduction in seizure frequency during the chronic phase. LEV was administrated orally or via nasogastric tubes as an add-on agent during acute (n=3; age 8-10 years) and chronic (n=3; age 19-30 years) AERRPS. RESULTS In the acute phase, administration of LEV (50-60 mg/kg/d) in combination with phenobarbital (n=3; peak 57.9-76.1 μg/ml) and potassium bromide (n=2; 30-36 mg/kg/d)) resulted in successful reduction of intravenous barbiturate dosage and withdrawal from artificial ventilation. In the chronic phase, seizure frequency reduced by >75% for 5-18 months with LEV 750-1500 mg/d. CONCLUSION LEV may affect seizure control in AERRPS, particularly during the chronic phase, through its unique action of inhibition of excitatory neurotransmitter release. The regimen of oral barbiturate, potassium bromide and LEV would be worth for trial during the acute phase of AERRPS.
