BACKGROUND
Status epilepticus in pregnancy (SEP) is rare and life-threatening for both mother and fetus. There are well-established guidelines for the management of women with epilepsy during pregnancy; however, there is little evidence guiding the management of SEP, leading to uncertainty among treating physicians. Therefore, this survey aims to investigate the real-world practices of physicians treating SEP to explore management approaches for improvements in care.
METHODS
An anonymous, electronic survey was created and distributed to neurointensivists and neurologists between September and December 2021.
RESULTS
One hundred physicians initiated the survey and 95 completed it in full: 87 (87%, 87/100) identified neurology as their primary specialty, 31 had subspecialty training in neurocritical care, and 48 had subspecialty training in epilepsy and/or clinical neurophysiology. Over half of the survey respondents (67%, 67/100) reported having participated in the management of SEP, with 48.9% (49/98) having done so in the past year. Most survey respondents (73%, 73/100) reported that their management approach to SEP is different than that of non-pregnant patients. Survey respondents were more likely to involve epilepsy consultants when treating SEP (58.5%, 58/99) and the vast majority involved Obstetrics/Maternal Fetal Medicine consultants (90.8%, 89/98). Survey respondents showed a clear preference for levetiracetam (89.7%, 87/97) in the treatment of benzodiazepine refractory status epilepticus followed by lacosamide (61%, 60/98) if an additional second line agent was needed. Valproate and phenobarbital were unlikely to be used. There was less agreement for the management of refractory and super-refractory SEP.
CONCLUSIONS
Levetiracetam is the most frequently used anti-seizure medication (ASM) for benzodiazepine-refractory SEP. Survey participants tended to manage SEP differently than in non-pregnant patients including greater involvement of interdisciplinary teams as well as avoidance of ASMs associated with known teratogenicity.

Epilepsy is the most widespread neurological disorder in Africa, affecting an estimated 25 million people. The disorder is characterized by recurrent seizures, which can be caused by a variety of factors, including past trauma, central nervous system infections, and genetic disorders. Diagnosis and treatment of epilepsy are challenging in African patients due to several factors, including the low socioeconomic status of the residents and limited access to appropriate medication. Phenobarbital remains the only drug widely available to patients, but it is not always effective and can have significant side effects. In addition to the medical challenges, individuals with epilepsy also face a lot of social stigmas in Africa. Widespread superstitions and false beliefs lead to prejudices against these people, making it difficult for them to live fulfilling social lives. With the development of new treatment modalities, such as gene therapy, stem cell therapy, and P-glycoprotein inhibitors, it is more important now than ever to increase the research output for the African region to create the best possible treatment and maximize patient outcomes.

Background Status epilepticus (SE) is a common neurologic emergency with high rates of mortality and morbidity. Objective To analyze the clinical characteristics, causes, management, and outcomes of patients with SE in a tertiary care hospital in Morocco. Methods A retrospective study was conducted from January 2019 to December 2021, including all patients admitted to the medico-surgical general intensive care unit (ICU) with a diagnosis of SE. We recorded demographic characteristics, SE clinical history, management, causes, and discharge outcomes. Results Overall, 82 patients with SE were included, the median age was 39.5 years (18-95), 61% of the patients were male, the majority of semiology was convulsive SE (93%, N: 77), epilepsy of unknown cause was the most common diagnosis (41.2%, N: 34), and the most known etiology was acute/subacute cerebrovascular events (12 patients, 14.4%). All patients received benzodiazepines, 96.4% of them received phenobarbital as a second line of treatment, 65 patients required anesthesia, 52 patients developed one complication at least - the most common complication being systemic infection, and the mortality rate was noted to be 38% among patients with SE (N: 31). In this study, the factors associated with mortality were ischemic stroke (as an etiology of SE (p=0.048), history of epilepsy (p=0.005), poor therapeutic adherence (p=0.001), cardiovascular complications, presence of multiple complications (p=0.0001), pneumonia (p=0.0001), and the recurrence of SE (p=0.050). Conclusions We provide a single-center retrospective analysis of admissions in SE and note that mortality among SE patients is high in our settings. Improving prehospital emergency care and implementing elective ICU admission for patients at high risk could improve the mortality rate.

Review
Experimental studies reveal that caffeine (trimethylxanthine) at subconvulsive doses, distinctly reduced the anticonvulsant activity of numerous antiseizure medications (ASMs) in rodents, oxcarbazepine, tiagabine and lamotrigine being the exceptions. Clinical data based on low numbers of patients support the experimental results by showing that caffeine (ingested in high quantities) may sharply increase seizure frequency, considerably reducing the quality of patients' lives. In contrast, this obviously negative activity of caffeine was not found in clinical studies involving much higher numbers of patients. ASMs vulnerable to caffeine in experimental models of seizures encompass carbamazepine, phenobarbital, phenytoin, valproate, gabapentin, levetiracetam, pregabalin and topiramate. An inhibition of R-calcium channels by lamotrigine and oxcarbazepine may account for their resistance to the trimethylxanthine. This assumption, however, is complicated by the fact that topiramate also seems to be a blocker of R-calcium channels. A question arises why large clinical studies failed to confirm the results of experimental and case-report studies. A possibility exists that the proportion of patients taking ASMs resistant to caffeine may be significant and such patients may be sufficiently protected against the negative activity of caffeine.

INTRODUCTION
There is no consensus regarding the efficacy of add-on therapy with levetiracetam (LEV) in the treatment of seizures in neonates. The aim of this study was to evaluate the efficacy of add-on therapy with LEV for achieving >80% seizure reduction after phenobarbital (PB) treatment.
METHODS
Retrospective cohort study of near term neonates admitted to the neonatal intensive care unit with EEG-confirmed seizures despite treatment with PB as first-line therapy and using LEV as 2nd-, 3rd- or 4th-line treatment. Antiseizure medication was administered according to national guidelines. All neonates were monitored with 2-channel amplitude-integrated electroencephalography. The total seizure burden in minutes, 2 h before and 4 h after administration of LEV, was calculated using raw EEG. Primary outcome was the efficacy of LEV in achieving >80% seizure reduction. The efficacy of additional midazolam (MDZ) and lidocaine (LDC) was also calculated.
RESULTS
A total of 47 full-term neonates were included. The mean total loading dose of LEV was 40 mg/kg (36-44 mg/kg). Seizure etiology consisted of hypoxic-ischemic encephalopathy (n = 11), hemorrhagic or ischemic stroke (n = 16), central nervous system infection (n = 8), genetic (n = 8), metabolic disorders (n = 3), and unknown (n = 1). Following LEV administration, >80% seizure reduction was observed in 17% (8/47) of neonates, whereas it was 23% (6/26) after MDZ and 92% (23/25) after LDC administration.
DISCUSSION
Although the cumulative loading dose of LEV was low and the group of infants studied was heterogeneous, the efficacy of LEV as add-on therapy for the treatment of seizures in neonates was limited. The highest seizure reduction rate was seen after LDC administration.

Generalized tetanus is still a global concern with a mortality rate of up to 50%, especially in low and middle-income countries. We reported a 23-year-old man from Afghanistan admitted to emergency department, with the chief complaint of generalized severe spasms and lockjaw. The patient had skin lesions and had never been vaccinated against tetanus. He intubated and admitted to the intensive care unit (ICU) with diagnose of severe generalized tetanus. After receiving tetanus immunoglobulin and intravenous metronidazole, a combination therapy of midazolam, propofol, atracurium, and morphine was administered. Due to the refractory muscular spasms intravenous phenobarbital started and little by little recovery was achieved. The patient receiving the first two doses of the Td vaccine, and discharged on Day 42 of hospitalization with no symptom recurrence. This case management showed adding phenobarbital to severe tetanus treatment regimen could significantly reduce refractory spasm caused by tetanus, also decrease other medication requirement.

OBJECTIVE
To describe the profile of dispensation of mental health drugs by analyzing trends in use before and during the COVID-19 pandemic within the Unified Health System (Sistema Único de Saúde [SUS]).
METHODS
Pharmacoepidemiological study based on the retrospective analysis of records regarding the dispensation of psychotropic medicines in the SUS database in the state of Minas Gerais between 2018 and 2021, considering the periods before (2018-2019) and during the COVID-19 pandemic (2020-2021). A database with the records of dispensation of municipalities was created, and the consistency of releases was verified using the Analysis of Variance (ANOVA) test. Medicine consumption was measured in a defined daily dose (DDD) per 1,000 inhabitants/day for SUS, and the difference between periods was evaluated using Student's t-test.
RESULTS
During the COVID-19 pandemic, there was an increase in the consumption of psychotropic drugs in SUS-MG. The most consumed medicines were fluoxetine hydrochloride, diazepam and phenobarbital sodium (DDD=5.89; 3.42; 2.49) in the Basic Pharmaceutical Services Component(CBAF), and olanzapine, risperidone and quetiapine hemifumarate (DDD=0.80; 0.47; 0.38) in the Specialized Pharmaceutical Services Component (CEAF). The highest percentage increase in consumption was attributed to clonazepam (75.37%) and lithium carbonate (35.35%), in CBAF, and levetiracetam (3,000.00%) and memantine hydrochloride (340.0%) in CEAF.
CONCLUSION
The change in the psychotropic drug dispensation profile during the COVID-19 pandemic highlights the need to produce more studies to complete, confirm or rule out this profile and monitor the use of psychotropic drugs by the population in the post-pandemic context.

Amyotrophic lateral sclerosis (ALS) is a devastating fatal neurodegenerative disease with no cure. Receptor-interacting protein kinase 1 (RIPK1) has been proposed to mediate pathogenesis of ALS. Primidone has been identified as an old drug that can also inhibit RIPK1 kinase. We conducted a drug-repurposing biomarker study of primidone as a RIPK1 inhibitor using SOD1 mice and ALS patients. SOD1 mice treated with primidone showed significant delay of symptomatic onset and improved motor performance. One-hundred-sixty-two ALS participants dosed daily with primidone (62.5 mg) completed 24-week follow-up. A significant reduction was showed in serum levels of RIPK1 and IL-8, which were significantly higher in ALS patients than that of healthy controls (P < 0.0001). Serum RIPK1 levels were correlated positively with the severity of bulbar symptoms (P < 0.05). Our study suggests that serum levels of RIPK1 and IL-8 in peripheral can be used as clinical biomarkers for the activation of RIPK1 in central nervous system in human ALS patients. Repurposing primidone may provide a promising therapeutic strategy for ALS. The effect of primidone for the treatment of other inflammatory diseases may also be considered, since the activation of RIPK1 has been implicated in mediating a variety of inflammatory diseases including COVID-19-associated cytokine release syndrome (CRS). (ChiCTR2200060149).

OBJECTIVES
Indicatively, phenobarbital can impair thyroid function in adults and children. The present research aims to evaluate the thyroid hormone levels in preterm neonates who had received phenobarbital treatment.
MATERIALS &METHODS
This study was conducted on preterm neonates who weighed less or equal to 2500 g when phenobarbital was prescribed for treatment in the first 15 days of life. TSH and total T4 measurements were performed before and three months after initiation of phenobarbital.
RESULTS
In this study, the sum of preterm neonates stood at 94, of which 53 were girls, with a mean birth weight of 2004.41 ± 315.41g. Weight of 8.5% were under 1500 g. The mean gestational age was estimated at 33.64 ± 2.01 weeks. Mean T4 levels were 12.24 ± 1.96 and 12.07 ± 1.95 (p=0.334), and mean TSH levels were 5.34 ± 2.14 and5.15 ± 2.15 (p=0.376) before and after prescribing phenobarbital, respectively. The same results were compared based on sex, gestational age, birth weight, and height for T4 and TSH and T4 based on head circumference. The only significant difference was TSH in preterm infants with head circumference <32 cm before and after prescribing phenobarbital (p=0.030).
CONCLUSION
In preterm newborns that had less than 2500 g birth weight, phenobarbital did not significantly alter the serum thyroid hormone levels.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Syndrome and Stevens-Johnson Syndrome (SJS) are severe cutaneous adverse reactions to drugs. Those reactions which are rare in children can be especially severe and challenging to diagnose and manage. Herein we present a 59-month-old male who presented with a rash, fever, and multiple organ dysfunction initiation of Phenobarbital for epilepsy. Diagnosis of ovelaping SJS and DRESS syndrome had been made based on clinical manifestations accompanied with skin biopsy according to RegisSCAR diagnostic criteria. A therapy with intravenous immune globulin (IVIG), corticosteroids and supportive care was given successfully for the patient. This case underscored the significance of promptly and effectively recognizing and managing these intricate reactions.
