Abstract
Magnesium is an essential cation present in the body that participates in the regulation of various vital body functions. Maintaining normal level of magnesium is essential for proper brain functions by regulating the activities of numerous neurotransmitters and their receptors. Various studies have been reported that magnesium level is found to be declined in both neurological and psychiatric diseases. Declined magnesium level in the brain initiates various cumbersome effects like excitotoxicity, altered blood-brain permeability, oxidative stress, and inflammation, which may further worsen the disease condition. Shreds of evidence from the experimental and clinical studies proved that exogenous administration of magnesium is useful for correcting disease-induced alterations in the brain. But one of the major limiting factors in the use of magnesium for treatment purposes is its poor blood-brain barrier permeability. Various approaches like the administration of its organic salts as pidolate and threonate forms, and the combination with polyethylene glycol or mannitol have been tried to improve its permeability to make magnesium as a suitable drug for different neurological disorders. These results have shown their experimental efficacy in diseased animal models, but studies regarding the safety and efficacy in human subjects are currently underway. We present a comprehensive review on the role of magnesium in the maintenance of normal functioning of the brain and various approaches for improving its BBB permeability.

Abstract
FIRES is defined as a disorder that requires a prior febrile infection starting between 2 weeks and 24 h before the onset of the refractory status epilepticus with or without fever at the onset of status epilepticus. The patients, previously normal, present in the acute phase recurrent seizures and status epilepticus followed by a severe course with usually persistent seizures and residual cognitive impairment. Boundary with "new onset refractory status epilepticus (NORSE) has not clearly established. Pathogenetic hypothesis includes inflammatory or autoimmune mechanism with a possible genetic predisposition for an immune response dysfunction.Various types of treatment have been proposed for the treatment of the acute phase of the disorder to block the rapid seizures evolution to status epilepticus and to treat status epilepticus itself. Prognosis is usually severe both for control of the seizures and for cognitive involvement.FIRES is an uncommon but severe disorder which must be carefully considered in the differential diagnosis with other epileptic encephalopathy.

The effects of intraoperative magnesium sulfate administration on emergence agitation and delirium in pediatric patients: A systematic review and meta-analysis of randomized controlled trials. Paediatr Anaesth 2022; 32:522-530. [PMID: 34861083 DOI: 10.1111/pan.14352] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 10/25/2021] [Accepted: 11/22/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND The role of intraoperative magnesium for the prevention of emergence agitation or delirium is unclear as there have been conflicting results reported by several randomized controlled trials. AIMS The aim of this study was to investigate the effect of magnesium sulfate on emergence agitation or emergence delirium in pediatric patients. METHODS Electronic databases, including PubMed, EMBASE, CENTRAL, CINAHL, Scopus, and Web of Science, were searched to identify studies which evaluated the effects of magnesium on postoperative emergence agitation or emergence delirium. The primary outcome was the incidence of emergence agitation or emergence delirium during the post-anesthesia stay. The secondary outcome was the agitation or delirium score upon admission to the post-anesthesia care unit. We estimated the odds ratio and standardized mean difference using a random-effect model. RESULTS A total of 712 pediatric patients from 10 randomized controlled trials were included in the final analysis. The incidence of emergence agitation or emergence delirium was 29.7% in the magnesium group and 50.5% in the control group. The pooled effect size revealed that the administration of magnesium sulfate significantly reduced the incidence of postoperative emergence agitation or emergence delirium in pediatric patients undergoing surgery with general anesthesia (Odds ratio, 0.31; 95% confidence interval, 0.15 to 0.64; p = .002). Additionally, children in the magnesium group reported significantly lower agitation or delirium scores than those in the control group (standardized mean difference, -0.70; 95% confidence interval, -1.15 to -0.24; p = .003). CONCLUSION The administration of magnesium sulfate reduced the incidence and severity of emergence agitation or emergence delirium in pediatric patients after the use of general anesthesia during surgery.

Abstract
Perampanel is a novel antiepileptic drug, which antagonises AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) glutamate receptor. We describe perampanel as an adjunctive treatment for FIRES (febrile infection-related epilepsy syndrome) and other drug-resistant epilepsies. A single-centre, observational, retrospective study involving 20 pediatric patients was conducted. Perampanel was started for three patients with FIRES, achieving seizure cessation in two patients within a day and on days 19 and 32 of illness. Doses used ranged from 4 to 12 mg/day, without any adverse effects reported or discontinuation of therapy. Responder-rate for other drug-resistant epilepsies is 25%. Median time to achieve ≥50% seizure reduction was 80 days (range: 26-326 days). Adverse effect reported in 47% of the patients includes central nervous system-related, and thrombocytopenia. Eight patients discontinued perampanel, because of ineffectiveness or adverse effects. The median time on perampanel before discontinuation was 179 days (range: 94-345 days). Perampanel may be of benefit in pediatrics FIRES and is of utility in other drug-resistant epilepsies.

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

Abstract
Magnesium (Mg2+) is the 2nd most abundant intracellular cation, which participates in various enzymatic reactions; there by regulating vital biological functions. Magnesium (Mg2+) can regulate several cations, including sodium, potassium, and calcium; it consequently maintains physiological functions like impulse conduction, blood pressure, heart rhythm, and muscle contraction. But, it doesn't get much attention in account with its functions, making it a "Forgotten cation". Like other cations, maintenance of the normal physiological level of Mg2+ is important. Its deficiency is associated with various diseases, which point out to the importance of Mg2+ as a drug. The roles of Mg2+ such as natural calcium antagonist, glutamate NMDA receptor blocker, vasodilator, antioxidant and anti-inflammatory agent are responsible for its therapeutic benefits. Various salts of Mg2+ are currently in clinical use, but their application is limited. This review collates all the possible mechanisms behind the behavior of magnesium as a drug at different disease conditions with clinical shreds of evidence.

Abstract
Purpose: Established tonic–clonic status epilepticus (SE) does not stop in one-third
of patients when treated with an intravenous (IV) benzodiazepine bolus
followed by a loading dose of a second antiseizure medication (ASM). These
patients have refractory status epilepticus (RSE) and a high risk of
morbidity and death. For patients with convulsive refractory status
epilepticus (CRSE), we sought to determine the strength of evidence for 8
parenteral ASMs used as third-line treatment in stopping clinical CRSE. Methods: A structured literature search (MEDLINE, Embase, CENTRAL, CINAHL) was
performed to identify original studies on the treatment of CRSE in children
and adults using IV brivaracetam, ketamine, lacosamide, levetiracetam (LEV),
midazolam (MDZ), pentobarbital (PTB; and thiopental), propofol (PRO), and
valproic acid (VPA). Adrenocorticotropic hormone (ACTH), corticosteroids,
intravenous immunoglobulin (IVIg), magnesium sulfate, and pyridoxine were
added to determine the effectiveness in treating hard-to-control seizures in
special circumstances. Studies were evaluated by predefined criteria and
were classified by strength of evidence in stopping clinical CRSE (either as
the last ASM added or compared to another ASM) according to the 2017
American Academy of Neurology process. Results: No studies exist on the use of ACTH, corticosteroids, or IVIg for the
treatment of CRSE. Small series and case reports exist on the use of these
agents in the treatment of RSE of suspected immune etiology, severe
epileptic encephalopathies, and rare epilepsy syndromes. For adults with
CRSE, insufficient evidence exists on the effectiveness of brivaracetam
(level U; 4 class IV studies). For children and adults with CRSE,
insufficient evidence exists on the effectiveness of ketamine (level U; 25
class IV studies). For children and adults with CRSE, it is possible that
lacosamide is effective at stopping RSE (level C; 2 class III, 14 class IV
studies). For children with CRSE, insufficient evidence exists that LEV and
VPA are equally effective (level U, 1 class III study). For adults with
CRSE, insufficient evidence exists to support the effectiveness of LEV
(level U; 2 class IV studies). Magnesium sulfate may be effective in the
treatment of eclampsia, but there are only case reports of its use for CRSE.
For children with CRSE, insufficient evidence exists to support either that
MDZ and diazepam infusions are equally effective (level U; 1 class III
study) or that MDZ infusion and PTB are equally effective (level U; 1 class
III study). For adults with CRSE, insufficient evidence exists to support
either that MDZ infusion and PRO are equally effective (level U; 1 class III
study) or that low-dose and high-dose MDZ infusions are equally effective
(level U; 1 class III study). For children and adults with CRSE,
insufficient evidence exists to support that MDZ is effective as the last
drug added (level U; 29 class IV studies). For adults with CRSE,
insufficient evidence exists to support that PTB and PRO are equally
effective (level U; 1 class III study). For adults and children with CRSE,
insufficient evidence exists to support that PTB is effective as the last
ASM added (level U; 42 class IV studies). For CRSE, insufficient evidence
exists to support that PRO is effective as the last ASM used (level U; 26
class IV studies). No pediatric-only studies exist on the use of PRO for
CRSE, and many guidelines do not recommend its use in children aged <16
years. Pyridoxine-dependent and pyridoxine-responsive epilepsies should be
considered in children presenting between birth and age 3 years with
refractory seizures and no imaging lesion or other acquired cause of
seizures. For children with CRSE, insufficient evidence exists that VPA and
diazepam infusion are equally effective (level U, 1 class III study). No
class I to III studies have been reported in adults treated with VPA for
CRSE. In comparison, for children and adults with established convulsive SE
(ie, not RSE), after an initial benzodiazepine, it is likely that loading
doses of LEV 60 mg/kg, VPA 40 mg/kg, and fosphenytoin 20 mg PE/kg are
equally effective at stopping SE (level B, 1 class I study). Conclusions: Mostly insufficient evidence exists on the efficacy of stopping clinical CRSE
using brivaracetam, lacosamide, LEV, valproate, ketamine, MDZ, PTB, and PRO
either as the last ASM or compared to others of these drugs.
Adrenocorticotropic hormone, IVIg, corticosteroids, magnesium sulfate, and
pyridoxine have been used in special situations but have not been studied
for CRSE. For the treatment of established convulsive SE (ie, not RSE), LEV,
VPA, and fosphenytoin are likely equally effective, but whether this is also
true for CRSE is unknown. Triple-masked, randomized controlled trials are
needed to compare the effectiveness of parenteral anesthetizing and
nonanesthetizing ASMs in the treatment of CRSE.

Abstract
BACKGROUND Refractory status epilepticus (RSE) represents a serious medical condition requiring early and targeted therapy. Given the increasing number of elderly or multimorbid patients with a limitation of life-sustaining therapy (LOT) or within a palliative care setting (PCS), guidelines-oriented therapy escalation options for RSE have to be omitted frequently. OBJECTIVES This systematic review sought to summarize the evidence for fourth-line antiseizure drugs (ASDs) and other minimally or non-invasive therapeutic options beyond guideline recommendations in patients with RSE to elaborate on possible treatment options for patients undergoing LOT or in a PCS. METHODS A systematic review of the literature in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, focusing on fourth-line ASDs or other minimally or non-invasive therapeutic options was performed in February and June 2020 using the MEDLINE, EMBASE and Cochrane databases. The search terminology was constructed using the name of the specific ASD or therapy option and the term 'status epilepticus' with the use of Boolean operators, e.g. "(brivaracetam) AND (status epilepticus)". The respective Medical Subject Headings (MeSH) and Emtree terms were used, if available. RESULTS There is currently no level 1, grade A evidence for the use of ASDs in RSE. The best evidence was found for the use of lacosamide and topiramate (level 3, grade C), followed by brivaracetam, perampanel (each level 4, grade D) and stiripentol, oxcarbazepine and zonisamide (each level 5, grade D). Regarding non-medicinal options, there is little evidence for the use of the ketogenic diet (level 4, grade D) and magnesium sulfate (level 5, grade D) in RSE. The broad use of immunomodulatory or immunosuppressive treatment options in the absence of a presumed autoimmune etiology cannot be recommended; however, if an autoimmune etiology is assumed, steroid pulse, intravenous immunoglobulins and plasma exchange/plasmapheresis should be considered (level 4, grade D). Even if several studies suggested that the use of neurosteroids (level 5, grade D) is beneficial in RSE, the current data situation indicates that there is formal evidence against it. CONCLUSIONS RSE in patients undergoing LOT or in a PCS represents a challenge for modern clinicians and epileptologists. The evidence for the use of ASDs in RSE beyond that in current guidelines is low, but several effective and well-tolerated options are available that should be considered in this patient population. More so than in any other population, advance care planning, advance directives, and medical ethical aspects have to be considered carefully before and during therapy.

Abstract
OBJECTIVE To investigate the factors in first-time adrenocorticotropic hormone (ACTH) therapy and their influence on spasm control time in infants with infantile spasms. METHODS A total of 72 infants with infantile spasms who were admitted from January 2008 to October 2013 were enrolled. Their clinical data were collected, and the exposure factors for infantile spasms were selected. A Cox proportional-hazards regression model analysis was performed for these factors to analyze their influence on spasm control time. RESULTS Clarification of the etiology (known or unexplained etiology), frequency of spasms before treatment, and presence or absence of combination therapy (ACTH used alone or in combination with magnesium sulfate) had a significant influence on spasm control time in infants with infantile spasms. The infants with a known etiology had a significantly shorter spasm control time than those with unexplained etiology, and the infants with a low frequency of spasms before treatment and receiving ACTH combined with magnesium sulfate early had a significantly longer spasm control time than their counterparts (P<0.05). CONCLUSIONS For infants with infantile spasms at initial diagnosis, etiology should be clarified, which may helpful for evaluating prognosis. A combination of ACTH and magnesium sulfate should be given as soon as possible, which may improve their prognosis.

RESULTS Clarification of the etiology (known or unexplained etiology), frequency of spasms before treatment, and presence or absence of combination therapy (ACTH used alone or in combination with magnesium sulfate) had a significant influence on spasm control time in infants with infantile spasms. The infants with a known etiology had a significantly shorter spasm control time than those with unexplained etiology, and the infants with a low frequency of spasms before treatment and receiving ACTH combined with magnesium sulfate early had a significantly longer spasm control time than their counterparts (P<0.05). CONCLUSIONS For infants with infantile spasms at initial diagnosis, etiology should be clarified, which may helpful for evaluating prognosis. A combination of ACTH and magnesium sulfate should be given as soon as possible, which may improve their prognosis.

Abstract
Febrile infection-related epilepsy syndrome (FIRES) is a rare catastrophic epileptic encephalopathy with a yet undefined etiology, affecting healthy children. It is characterized by acute manifestation of recurrent seizures or refractory status epilepticus preceded by febrile illness, but without evidence of infectious encephalitis. To date, the absence of specific biomarkers poses a significant diagnostic challenge; nonetheless, early diagnosis is very important for optimal management. FIRES is mostly irreversible and its sequelae include drug-resistant epilepsy and neuropsychological impairments. The treatment of FIRES represents a significant challenge for clinicians and is associated with low success rates. Early introduction of ketogenic diet seems to represent the most effective and promising treatment. This review aims to highlight the most recent insights on clinical features, terminology, epidemiology, pathogenesis, diagnostic challenges and therapeutic options.

Baek SJ, Byeon JH, Eun SH, Eun BL, Kim GH. Risk of low serum levels of ionized magnesium in children with febrile seizure. BMC Pediatr 2018; 18:297. [PMID: 30193581 PMCID: PMC6128998 DOI: 10.1186/s12887-018-1271-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Accepted: 08/30/2018] [Indexed: 11/13/2022] Open
Abstract
Background Suboptimal intake of magnesium become prevalent due to the modern diet of processed food low in magnesium. Magnesium may modulate seizure activity by antagonizing excitatory calcium influx through the N-methyl-D-aspartate receptor. Although hyponatremia has been reported to be common in febrile seizures, the most common form of seizure, little is known about the status of serum ionized magnesium. We therefore investigated the status of serum ionized magnesium (iMg2+) in children with febrile seizures and compared with controls. Methods We included all patients from 1 to 6 years old who had presented with febrile seizure to the pediatric emergency department at the Korea University Guro Hospital from July 2016 to February 2017. The control group comprised patients admitted to the hospital with febrile respiratory tract infections, but with no history of febrile seizure. Clinical data, blood tests, and electroencephalogram (EEG) results were reviewed using the patients’ medical records. Results A total of 133 patients with febrile seizure and 141 control patients were analyzed in the present study. As a result, hypomagnesemia (< 0.50 mmol/L) was more common in patients with febrile seizure than in controls (42.9% vs. 6.9%, p < 0.001) and it was an independent risk factor for febrile seizure (OR, odds ratio = 22.12, 95% CI = 9.23–53.02, P < 0.001). A receiver operating curve analysis revealed that serum iMg2+ levels < 0.51 mmol/L predicted the presence of febrile seizures with a sensitivity of 45.1% and a specificity of 92.6% (AUC, area under the curve = 0.731, 95% confidence interval = 0.671–0.791). When the patients with febrile seizure were divided in terms of a serum iMg2+ concentration of 0.51 mmol/L, there was no difference in clinical features. Conclusions Hypomagnesemia was more common and serum iMg2+ level was lower in patients with febrile seizures than in controls. However, further evidence is needed for the causal relationship between low magnesium and febrile convulsions.

Abstract
Introducción: El estado epiléptico superrefractario (EES) es una patología con importante morbimortalidad que afecta el ambiente neuronal según el tipo y duración de las crisis.Presentación del caso: Se presenta el caso de un escolar con estado epiléptico superrefractario y crisis multifocales. Se descartaron causas metabólicas, estructurales, infecciosas, toxicológicas y autoinmunes y se utilizaron diferentes manejos anticonvulsivantes sin respuesta, lográndose control de las crisis 6 semanas después del ingreso a UCI. Se realizó un seguimiento de 12 años, periodo en el que el paciente presentó múltiples recaídas del estado epiléptico asociadas a la presencia de epilepsia refractaria con múltiples tipos de crisis, en su mayoría vegetativas; además se dio involución cognitiva.Discusión: Esta forma de estado epiléptico corresponde al síndrome de estado epiléptico facilitado por fiebre (FIRES), entidad de posible origen inmunológico conocida por ser refractaria al tratamiento agudo y al manejo cró- nico de la epilepsia y que se presenta como secuela. Su evolución no se ha descrito a largo plazo y por tanto no hay consenso sobre el manejo en la fase crónica.Conclusión: Es importante considerar esta etiología en estado epiléptico superrefractario para utilizar de forma temprana diferentes estrategias terapéuticas, como la dieta cetogénica, que permitan, por un lado, controlar su condición crítica y las crisis epilépticas a largo plazo y, por el otro, mejorar el pronóstico cognitivo, logrando así un impacto en la calidad de vida.

Abstract
Magnesium is an essential chemical element in all organisms, intervening in most cellular enzymatic reactions; thus, its importance in homeostasis and as a therapeutic tool in highly challenging patients such as pediatrics. The primary purpose of this paper was to review the role of magnesium sulfate as an adjuvant drug in pediatric anesthesia. This compound already has the scientific backing in certain aspects such as analgesia or muscle relaxation, but only theoretical or empirical backing in others such as organ protection or inflammation, where it seems to be promising. The multitude of potential applications in pediatric anesthesia, its high safety, and low cost make magnesium sulfate could be considered a Super Adjuvant.
