Ketogenic diets therapy in the management of epileptic spasms syndrome

Infantile Epileptic Spasm Syndrome (IESS) is a group of infantile spasm syndromes of various etiologies that typically present in early infancy, predispose to refractory epilepsy, and leave intellectual disability. Ketogenic diet therapy (KDT) is a non-pharmacologic treatment modality for medically refractory IESS. Recent scientific evidence supported the efficacy, safety, and tolerability of KDT for the treatment of IESS. KDT not only reduces the frequency of seizures in infants with IESS, but also improve their cognition and long-term prognosis. Recently, it has also received increasing attention as a potential treatment for neurological disorders. This reviewed the recent research progress of KDTs for the treatment of IESS, and discussed the different types and the mechanisms of KDTs, the expansion of KDT applications, the influencing factors, and future research issues.

The protective effect of DMI on hippocampus EEG, behavioral and biochemical parameters in hypoxia-induced seizure on neonatal period.

Hypoxia-Induced Neonatal Seizure (HINS) is a prevalent type of seizure in infants caused by hypoxic conditions, which can lead to an increased risk of epilepsy, learning disabilities, and cognitive impairments later in life. This study focuses on examining the effects of dimethyl itaconate (DMI) on cognition, motor coordination, and anxiety-like behavior in male rats that have experienced HINS. 42 male Wistar newborn rats (PND10) were randomly divided into six groups (n = 7). 1) Control (Vehicle only); received DMI solvent (0.1ml) without applying hypoxia. 2-3) DMI; receiving (20 and 50 mg/kg; i.p). 4) HINS; they were placed in a hypoxia chamber with 7% oxygen and 93% nitrogen concentration for 15 minutes. 5-6) DMI+HINS; received DMI (20 and 50 mg/kg; i.p) 24h before hypoxia. Behavioral tests including; Novel object recognition test, Rotarod, Parallel bar, Open field and elevated plus maze (EPM); started at age 45 after birth. After behavioral tests, the hippocampal CA1 region local EEG was recorded in all groups. Then the brain hippocampus tissue was isolated and the amount of MDA, SOD, NO, and Thiol was measured by ELISA method. Data showed that the administration of DMI improved motor symptoms, anxiety-like behaviors, and cognition in HINS rats (p<0.05). EEG power in the HINS group decreased significantly compared to other experimental groups (p<0.05). Biochemical observations showed that DMI significantly reduced oxidative stress and inflammation in the hippocampal tissue of HINS rats (p<0.05). Increased hippocampal oxidative stress and inflammation can be effective in the occurrence of behavioral disorders observed in HINS rats. While DMI improved these behavioral impairments by reducing oxidative stress and inflammation.

The Use of Midazolam as an Antiseizure Medication in Neonatal Seizures: Single Center Experience and Literature Review.

Existing therapeutic alternatives for neonatal crises have expanded in recent decades, but no consensus has been reached on protocols based on neonatal seizures. In particular, little is known about the use of midazolam in newborns. The aim of our study is to evaluate the response to midazolam, the appearance of side effects, and their impact on therapeutic decisions. This is a STROBE-conformed retrospective observational study of 10 patients with neonatal seizures unresponsive to common antiseizure drugs, admitted to San Marco University Hospital's neonatal intensive care (Catania, Italy) from September 2015 to October 2022. In our database search, 36 newborns were treated with midazolam, but only ten children met the selection criteria for this study. Response was assessed both clinically and electrographic. Only 4 patients at the end of the treatment showed a complete electroclinical response; they were full-term infants with a postnatal age greater than 7 days. Non-responders and partial responders are all premature (4/10) or full-term neonates who started therapy in the first days of life (< 7th day) (2/10). Neonatal seizures in preterm show a lower response rate to midazolam than seizures in full-term infants, with poorer prognosis. Liver and renal function and central nervous system development are incomplete in premature infants and the first days of life. In this study, we show that midazolam, a short-acting benzodiazepine, appears to be most effective in full-term infants and after 7 days of life.

The Spectrum of Self-Limited Infantile Epilepsy Syndromes

AbstractInfantile epilepsy syndromes' nomenclature has changed over time. The International League Against Epilepsy (ILAE) revised its 2021 classification and definition of epilepsy syndromes in neonates and infants, replacing the term “benign” with “self-limited,” and now identifies them as “self-limited infantile epilepsy” (SeLIE). SeLIE is characterized by seizures that begin during infancy and resolve spontaneously with normal developmental progress. The recognition of infantile seizures with favorable outcomes dates back more than 60 years, as noted by Fukuyama in Japan. Thirty years later, Watanabe et al reported benign focal seizures in infancy, with the majority of cases being nonfamilial. These seizures' self-limited nature during infancy has since been acknowledged in various countries, spanning diverse ethnic populations beyond Japan. Infants who undergo such seizures are now recognized as having self-limited nonfamilial infantile epilepsy (SeLNFIE). Initially, Vigevano et al detailed the familial variant in five infants, coining the term “benign familial infantile seizures” to characterize this condition, now known as self-limited familial infantile epilepsy (SeLFIE). SeLNFIE and SeLFIE may present similarly with the exception of a positive family history. After the initial description and classification of these syndromes (familial and nonfamilial) in the ILAE's 1989 Classification of Epilepsies and Epileptic Syndromes, several less frequently encountered related syndromes have been recognized. These conditions comprise a spectrum including SeLFIE with choreoathetosis and paroxysmal dyskinesia, now termed infantile convulsions with paroxysmal choreoathetosis syndrome (ICCA); self-limited focal epilepsy in infancy with midline spikes and waves during sleep (SeLIMSE); self-limited infantile seizures with mild gastroenteritis (SeLISwG); SeLFIE associated with familial hemiplegic migraine (FHM); and self-limited familial neonatal-infantile epilepsy (SeLFNIE). This review aims to document the prevalence of these SeLIEs, elucidate their unique characteristics, and underscore their self-limited nature.

Dravet syndrome an unusual cause of atypical febrile seizure: a case report

Dravet syndrome is a rare refractory epileptic encephalopathy with an underlying genetic basis. It presents with recurrent febrile seizures in infancy. Though development is normal in infancy, neurodevelopmental delay and neurologic disability begin after the onset of seizure at the age of around 2-4 years. The outcome can be improved by early diagnosis (genetic testing for SCN1A gene) and timely treatment. In this case report we are presenting a 3-year-old female child with recurrent refractory epilepsy associated with fever and was diagnosed with Dravet syndrome.

Diagnostic pathway and management of first seizures in infants with Sturge-Weber syndrome.

Sturge-Weber syndrome (SWS) is a rare neurocutaneous syndrome, frequently associated with pharmaco-resistant, early-onset epilepsy. Optimal seizure control is paramount to maximize neurodevelopment. A single-centre case series of 49 infants explored early SWS care. Ninety-two per cent of children developed seizures aged 0 to 3 years; 55% of cases were before diagnostic magnetic resonance imaging (MRI) or tertiary referral. Delay in SWS diagnosis affected 31% of infants because of a lack of gadolinium enhancement for initial MRI. First seizures were frequently prolonged, with phenytoin administration necessary in 46%. Presymptomatic antiseizure medication prophylaxis (n = 8/49) decreased seizure burden. No patients on antiseizure medication prophylaxis suffered status epilepticus for longer than 30 minutes, and half of them (n = 4) had not developed seizures at last follow-up (aged 2-10 years). A parental survey enabled further service evaluation. Eighty-three per cent of parents considered local clinicians' understanding of SWS inadequate: 61% felt insufficiently informed about SWS and 81% received no epilepsy education before seizures. To overcome the identified shortfalls, guidelines towards improving and standardizing SWS management are proposed.

Lights, Sirens, and Load: Anticipatory emergency medical treatment planning causes cognitive load during emergency response driving among paramedicine students

Paramedics face various unconventional and secondary task demands while driving ambulances, leading to significant cognitive load, especially during lights-and-sirens responses. Previous research suggests that high cognitive load negatively affects driving performance, increasing the risk of accidents, particularly for inexperienced drivers. The current study investigated the impact of anticipatory treatment planning on cognitive load during emergency driving, as assessed through the use of a driving simulator. We recruited 28 non-paramedic participants to complete a simulated baseline drive with no task and a cognitive load manipulation using the 1-back task. We also recruited 18 paramedicine students who completed a drive while considering two cases they were travelling to: cardiac arrest and infant seizure, representing varying difficulty in required treatment. The results indicated that both cases imposed considerable cognitive load, as indicated by NASA Task Load Index responses, comparable to the 1-back task and significantly higher than driving with no load. These findings suggest that contemplating cases and treatment plans may impact the safety of novice paramedics driving ambulances for emergency response. Further research should explore the influence of experience and the presence of a second individual in the vehicle to generalise to broader emergency response driving contexts.

Current Evidence: Seizures in Extremely Low Gestational Age Newborns (ELGANs).

Extremely low gestational age newborns (ELGANs) are born at or below 28 weeks of gestational age. Despite improved obstetric care, the incidence of preterm birth continues to rise in advanced countries. Preterm birth remains a major cause of infant mortality, and for infants who survive, neonatal seizures are a significant predictor of later neurologic morbidity. However, little is known about risk factors for neonatal seizures in ELGANs. Understanding the association between neonatal seizures and the development of other neurologic disorders is important given the increasing prevalence of ELGANs. Identifying risk factors that contribute to the development of neonatal seizures in ELGANs may offer insights into novel mechanisms of epileptogenesis in the developing brain and improvements in the prevention or treatment of seizures in preterm infants, including ELGANs. In this literature review, we outline the limitations of epidemiologic studies of neonatal seizures in ELGANs and discuss risk factors for neonatal seizures.

Falls in oxygen saturations accompany electrographic seizures in term neonates: an observational study

BackgroundEffective seizure detection is important however, clinical signs of seizure activity may be subtle in neonates. This study aimed to systematically investigate SpO2 and respiratory pattern changes associated with EEG seizures in term-born neonates.MethodAn observational study in term neonates at risk of seizures admitted to a single tertiary level neonatal intensive care unit. Synchronised high-resolution physiological data (ECG, pulse oximetry, respiration) and EEG/amplitude-integrated EEG (aEEG) monitoring were recorded. Sections of traces with evidence of clear EEG seizure activity were compared with physiological data recorded at the same time.Results22/44 (50%) neonates who had aEEG monitoring were noted to have electrographic seizures. Physiologic download measurements were available for 11 of these neonates. In nine of these, an acute drop in oxygen saturation (SpO2) of at least 5% was noted in at least one seizure. Accompanying apnoeas were noted in three neonates.ConclusionAcute decreases in SpO2 were seen in term neonates associated with seizures and these were not always accompanied by an apnoeic episode. Physiologic download in association with EEG monitoring may assist in improving seizure detection. Unexplained drops in SpO2 could indicate further investigation for possible seizures in at-risk neonates.ImpactA decrease in blood oxygen saturation (SpO2) associated with EEG seizures can occur in term infants with HIE or perinatal stroke.Drops in SpO2 associated with EEG seizures in term infants with HIE or stroke may occur in the absence of apnoeas.Unexplained acute falls in SpO2 in sick neonates may suggest possible seizures.Drops in SpO2 associated with seizures in term infants can occur over less than 3 minutes.Physiological monitoring alongside EEG monitoring could help to improve seizure detection.

Elevated S100B urine levels predict seizures in infants complicated by perinatal asphyxia and undergoing therapeutic hypothermia.

Seizures (SZ) are one of the main complications occurring in infants undergoing therapeutic hypothermia (TH) due to perinatal asphyxia (PA) and hypoxic ischemic encephalopathy (HIE). Phenobarbital (PB) is the first-line therapeutic strategy, although data on its potential side-effects need elucidation. We investigated whether: i) PB administration in PA-HIE TH-treated infants affects S100B urine levels, and ii) S100B could be a reliable early predictor of SZ. We performed a prospective case-control study in 88 PA-HIE TH infants, complicated (n=44) or not (n=44) by SZ requiring PB treatment. S100B urine levels were measured at 11 predetermined monitoring time-points from first void up to 96-h from birth. Standard-of-care monitoring parameters were also recorded. S100B significantly increased in the first 24-h independently from HIE severity in the cases who later developed SZ and requested PB treatment. ROC curve analysis showed that S100B, as SZ predictor, at a cut-off of 2.78 μg/L achieved a sensitivity/specificity of 63 and 84 %, positive/negative predictive values of 83 and 64 %. The present results offer additional support to the usefulness of S100B as a trustable diagnostic tool in the clinical daily monitoring of therapeutic and pharmacological procedures in infants complicated by PA-HIE.

Feeding metformin during pregnancy and lactation periods improved learning and memory impairment in the rat offspring exposed to febrile seizure: Role of oxidative stress and inflammatory response.

Many clinical evidences have reported the higher risk of seizure in young children and infants after exposure to hyperthermia, which more likely can cause brain damage and affect cognitive function, so, many researches were focused on prevention or treatment of febrile seizure (FS) with minimal adverse effects. Considering the potential effects of oxidative stress as a prominent trigger in FS, and demonstrating the anti-oxidant effects of metformin, the present study aimed to investigate the protective effect of metformin administration in prenatal and lactation periods in rat pups exposed to hyperthermia by which induced seizure. Pregnant rats were divided into six groups: (1) vehicle: pregnant rats received normal saline during pregnancy and lactation; (2) FS: pregnant rats received normal saline during pregnancy and lactation; (3-5) FS-Met50/100/150 mg/kg: pregnant rats received different doses of metformin including 50, 100 and 150 mg/kg during pregnancy and lactation; (6) Met150 mg/kg: pregnant rats received Met150 mg/kg during pregnancy and lactation. The male pups born to mothers received in all FS groups exposed to hyperthermia. All experimental groups were allowed to grow up, and after the lactation period, they were subjected for behavioural tests and biochemical analysis. According to the present findings, the prenatal and lactation exposure to the highest dose of metformin demonstrated significant difference with FS group in both behavioural and biochemical test analyses. Although the remaining doses of metformin were also effective, the much better results were reported with the highest dose of metformin (150 mg/kg). Interestingly, the highest dose of metformin administered alone demonstrated better result than vehicle in probe trial test. Considering the present research and related study in relation to metformin in ameliorating the epilepsy symptoms, there are numerous evidences on positive effect of metformin on seizure. Although the exact mechanism is unclear, the anti-oxidant effect of metformin is strongly supported.

Lacosamide for the Treatment of Seizures in Neonates and Infants: A Retrospective Assessment of Efficacy and Tolerability

BackgroundA retrospective study was conducted to assess the safety and efficacy of lacosamide in children aged less than 24 months. MethodsPatients were included if they were ≤24 months when they first received lacosamide; patients were excluded if they were enrolled in research studies investigating lacosamide or if there were insufficient data in the chart. Treatment response was assessed by reviewing charts and electroencephalographic reports to determine reduction in seizure burden. ResultsIn this sample, 53 of 86 patients (61.63%) in status epilepticus had good response to lacosamide, defined by ≥50% reduction in seizure burden. In addition, patients’ charts were reviewed until age 24 months to assess for any adverse effects attributed to maintenance lacosamide therapy, with adverse effects noted in three patients (abnormal movements in two patients, worsened seizures in one patient). ConclusionsThis study is among the largest retrospective chart reviews investigating the use of lacosamide in children and the first investigating the efficacy of lacosamide in children aged ≤24 months. Lacosamide was efficacious in reducing seizure burden in status epilepticus, and it was very well-tolerated in this age group. This study should prompt further investigation into the use of lacosamide in this age group.

Suppressive Effects of Docosahexaenoic Acid Intake on Increased Seizure Susceptibility after Growth Due to Febrile Seizures in Infancy.

Febrile seizures are seizures accompanied by a fever and frequently occur in children six months to five years of age. Febrile seizures are classified as simple or complex, and complex febrile seizures increase the risk of temporal lobe epilepsy after growth. Therefore, it is important to interfere with epileptogenesis after febrile seizures to prevent post-growth epilepsy. The present study challenged nutritional intervention using docosahexaenoic acid (DHA). Febrile seizures were induced in mice at the age of 10 d using a heat chamber, and seizure sensitivity was examined using pentylenetetrazol (PTZ) administration after growth. PTZ increased the seizure score and shortened the latency in the complex febrile seizure group compared to the control, hyperthermia and simple febrile seizure groups. Mice in the complex febrile seizure group showed abnormal electroencephalograms pre- and post-PTZ administration. Therefore, seizure susceptibility increases the episodes of complex febrile seizures. DHA supplementation after febrile seizures clearly suppressed the increased seizure susceptibility due to complex febrile seizures experienced in infancy. DHA also attenuated microglial activation after complex febrile seizures. Taken together, DHA suppressed microglial activation following complex febrile seizures, which may contribute to protecting the brain from post-growth seizures. The intake of DHA in infancy may protect children from high fever-induced developmental abnormalities.

O02 A case for diagnosis: ectodermal dysplasia and severe myelodysplasia

Abstract A 13-year-old girl was referred to us by our paediatric colleagues due to vulval dermatitis. She had a history of congenital hypotrichosis, microcephaly, abnormal dentition, dyshidrosis manifest as recurrent febrile seizures in infancy, recurrent infections, neutropaenia and macrocytosis. Her father and younger brother have a similarly striking phenotype, with complete absence of scalp and body hair, abnormal teeth, abnormal sweating, but normal nails. In addition, the father has required a stem cell transplant for myelodysplastic syndrome. None of the family have keratoderma, cleft palate, ectrodactyly or cardiomyopathy. DNA from our index patient was sent to Cardiff for the ectodermal dysplasia (ED) plus 70 gene panel for next-generation sequencing, but no mutation was found. Our paediatric haematology colleagues sequentially arranged dyskeratosis congenita panel, myeloid panel, and whole-exome sequencing for the younger brother, which did not identify a causative mutation. Unusually, all three were found to have mosaic trisomy 18. The transmission of trisomy 18 from parent to child as a mosaic trait in both generations is extremely unusual, and mosaic trisomy 18 has not been previously reported to cause ED. We would appreciate any input on a genetic diagnosis for this family with a distinctive phenotype consistent with hypohidrotic ED associated with myelodysplasia, with extensive genetic testing revealing a potentially spurious or coincidental mosaic trisomy 18 in all three affected family members.

Amplitude-Integrated Electroencephalography Evolution and Magnetic Resonance Imaging Injury in Mild and Moderate to Severe Neonatal Encephalopathy.

This study aimed to describe the evolution of amplitude-integrated electroencephalography (aEEG) in neonatal encephalopathy (NE) during therapeutic hypothermia (TH) and evaluate the association between aEEG parameters and magnetic resonance imaging (MRI) injury. aEEG data of infants who underwent TH were reviewed for background, sleep wake cycling (SWC), and seizures. Conventional electroencephalography (cEEG) background was assessed from the reports. Discordance of background on aEEG and cEEG was defined if there was a difference in the severity of the background. MRI injury (total score ≥ 5) was assessed by using the Weeke scoring system. A total of 46 infants were included; 23 (50%) with mild NE and 23 (50%) with moderate to severe NE. Comparing mild NE with moderate to severe NE, the initial aEEG background differed with more mild being continuous (70 vs. 52%), with fewer being discontinuous (0 vs. 22%) and flat tracing (0 vs. 4%), whereas burst suppression (4 vs. 4%) and low voltage (26 vs. 18%) did not differ. There was a notably common discordance between the background assessment on cEEG with aEEG in 82% with continuous and 40% low voltage aEEG background. MRI abnormalities were identified in four infants with mild NE and seven infants with moderate to severe NE. MRI injury was associated with aEEG seizures in infants with moderate to severe NE. aEEG seizures are useful to predict MRI injury in moderate to severe NE infants. There is a large discrepancy between aEEG, cEEG, and MRI in neonates treated by TH. · MRI injury was identified in 29% of moderate NE infants and in 50% of severe NE infants.. · aEEG seizures were associated with MRI injury in the moderate to severe NE infants.. · MRI injury was identified in 16% infants with mild NE.. · Mild NE infants with normal aEEG were unlikely to have MRI injury.. · There was a large discrepancy between aEEG, cEEG, and MRI in infants treated by TH..

Feasibility of ketogenic diet therapy variants for refractory epilepsy in neonates to infants under 2 years old

BackgroundKetogenic diet Therapy (KDT) has been reported as a possible beneficial management strategy for controlling seizures in infants aged <2 years, but the safety and efficacy of this therapy remain to be investigated. We investigated the achievability, tolerability, efficacy, and safety of KDT for patients under 2 years old. Materials and methodsInfants younger than 2 years old with pharmacoresistant epilepsy were enrolled in this prospective study. We divided cases into three age groups: I) neonates; II) infants aged 1–12 months; III) infants aged 12–24 months. KDT initiation protocol were administration through parenteral route, enteral route or oral feeding. Seizure reduction rate, physical growth, and adverse effects were assessed at monthly visit. ResultsThirteen patients who completed 6 months of KDT were recruited. There was one neonate in group I, 9 infants in group II, and 3 infants in group III. Eleven of them (11/13, 84.6%) were responders to KDT. All infants with underlying genetic etiology were seizure free after treating with KDT. The starting keto ratio was 1.1 mmol/L in group I, 2.3 mmol/L in group II, and 2.8 mmol/L in group III, which gradually approached 3:1–4:1 over 5–7 days. There were no symptomatic adverse effects or growth retardation in any of the study subjects. ConclusionsKDT is a promising alternative therapy with high feasibility, safety, and efficacy for pharmacoresistant epilepsy in infants under 2 years old, especially for those with genetic etiology. The starting keto ratio should be lower, and the keto ratio titration period should be longer than for children older than 2 years.

Incidence of Neonatal Seizures in China Based on Electroencephalogram Monitoring in Neonatal Neurocritical Care Units

Neonatal seizures pose a significant challenge in critical care, and continuous video electroencephalography (cEEG) monitoring holds promise for early detection of seizures. However, large-scale data on the incidence of neonatal seizures and monitoring systems in China are lacking. To determine the incidence of neonatal seizures in infants with high risk in China. A large, cross-sectional multicenter study was conducted from January 2017 to December 2018 in the neonatal intensive care units (NICUs) of 7 tertiary medical centers in China. Neonates with high risk were included, and cEEG monitoring was conducted. Data were collected between January 1, 2017, and January 31, 2020. The data were analyzed between January 2021 and January 2022. The incidence of neonatal seizures, categorized by etiology, and seizure burden. A total of 20 310 neonates with high risk were included (10 495 [51.7%] male; mean [SD] postmenstrual age, 37.7 [3.7] weeks), and seizures were observed in 3423 infants (16.9%). The highest proportion of seizures was attributed to acute neonatal encephalopathy (1448 [42.3%]). The incidence of seizures decreased with postmenstrual age and birth weight, with the highest occurrence observed in neonates with postmenstrual age of less than 28 weeks (237 of 879 [27.0%]) or birth weight of less than 1.0 kg (269 of 914 [29.4%]). Preterm infants had a higher proportion of moderate and severe seizure burdens compared with full-term infants (moderate severity: 248 of 1199 [20.7%] vs 454 of 2224 [20.4%]), but no significant differences were observed in etiology. Seizure burden was highest with genetic syndromes (49 of 188 [26.1%]), central nervous system malformations (33 of 127 [26.0%]), and inborn errors of metabolism (27 of 113 [23.9%]). During hospitalization, 7.8% of neonates with seizures died (267 neonates), with 81.3% of these cases having a moderate or severe seizure burden (217 neonates). Mortality was generally higher in preterm vs full-term infants (98 of 1199 [8.2%] vs 169 of 2224 [7.6%]) and increased with the severity of seizure burden (217 of 267 neonates with moderate or severe burden [81.3%]). This cross-sectional study of neonatal seizures underscores the substantial burden seizures pose to high-risk infants with brain injury in China, particularly those who are born prematurely or who have congenital conditions.

Factors Associated With Improved Pediatric Resuscitative Care in General Emergency Departments.

To describe the quality of pediatric resuscitative care in general emergency departments (GEDs) and to determine hospital-level factors associated with higher quality. Prospective observational study of resuscitative care provided to 3 in situ simulated patients (infant seizure, infant sepsis, and child cardiac arrest) by interprofessional GED teams. A composite quality score (CQS) was measured and the association of this score with modifiable and nonmodifiable hospital-level factors was explored. A median CQS of 62.8 of 100 (interquartile range 50.5-71.1) was noted for 287 resuscitation teams from 175 emergency departments. In the unadjusted analyses, a higher score was associated with the modifiable factor of an affiliation with a pediatric academic medical center (PAMC) and the nonmodifiable factors of higher pediatric volume and location in the Northeast and Midwest. In the adjusted analyses, a higher CQS was associated with modifiable factors of an affiliation with a PAMC and the designation of both a nurse and physician pediatric emergency care coordinator, and nonmodifiable factors of higher pediatric volume and location in the Northeast and Midwest. A weak correlation was noted between quality and pediatric readiness scores. A low quality of pediatric resuscitative care, measured using simulation, was noted across a cohort of GEDs. Hospital factors associated with higher quality included: an affiliation with a PAMC, designation of a pediatric emergency care coordinator, higher pediatric volume, and geographic location. A weak correlation was noted between quality and pediatric readiness scores.

Term-born infants with a perinatal stroke frequently had seizures and were prescribed anti-seizure medication at discharge.

We investigated the prevalence of seizures in term-born infants with a perinatal stroke in Swedish neonatal wards, assessed the anti-seizure medication prescribed and determined the accuracy of diagnostic codes. This cross-sectional study used data from the Swedish Neonatal Quality Register. The cases were infants born at ≥37 weeks in 2009-2018 and admitted to a neonatal ward in Stockholm County with a stroke diagnosis, confirmed by their medical chart. The controls were all Swedish infants born during those years. There were 76 infants with a confirmed perinatal stroke: 51 ischaemic and 25 haemorrhagic. Seizures were documented in 66/76 (87%) of infants with a stroke and 0.2% of the controls. Anti-seizure medication was administered to 64/66 (97%) infants with a stroke and seizures. In 60 cases, the drugs administered were specified, with phenobarbital used in 59/60 cases (98%). More than one drug was administered to 25/60 (42%) infants and 31/60 (52%) were discharged with anti-seizure medication. The positive predictive value for the stroke diagnostic codes was 80.5% (95% CI 76.5-84.5). Seizures were common in infants with a perinatal stroke. More than one anti-seizure drug was often required and many infants were on anti-seizure medication at discharge, against Swedish recommendations.

The Utilization of EEG Monitoring in Premature Infants with High-Grade Intraventricular Hemorrhage (P13-1.004)

<h3>Objective:</h3> We aimed to study the utility of continuous video electroencephalographic (cvEEG) monitoring as a screening tool for seizures in asymptomatic neonates found to have high-grade IVH. <h3>Background:</h3> High-grade intraventricular hemorrhage (IVH) is one of the possible complications of prematurity, and is considered one of the leading causes of seizures in premature infants. Neonatal seizures can be challenging to detect based on clinical symptoms alone and if left untreated, it can be associated with short- and long-term consequences. <h3>Design/Methods:</h3> We performed a comprehensive retrospective review on all premature infants born at the University of Alabama at Birmingham Regional Neonatal Intensive Care Unit from June 2018 to June 2021. We selected asymptomatic infants found to have high-grade (grade 3 and 4) IVH on head ultrasound who underwent cvEEG monitoring. Patient characteristics and comorbidities were then carefully studied and correlated with the screening EEG findings. <h3>Results:</h3> Among 27 premature infants with IVH enrolled in this study, 7 infants (26%) were found to have seizures detected on EEG. Detected seizures were only subclinical in 5 infants, while 2 infants had clinical in addition to subclinical seizures. Infants with seizures were relatively more premature, had a higher degree IVH, and lower APGAR scores at birth when compared to infants with no seizures. <h3>Conclusions:</h3> Our study suggests that EEG monitoring is vital when resources permit to screen for subclinical seizures in infants born with high-grade IVH. EEG screening should start as soon as IVH is suspected or discovered on imaging as early detection of seizures aid in prompt treatment. Since EEG monitoring is resource intensive, we suggest studying additional variables such as the degree of prematurity and APGAR scores to increase the yield of such screening studies. <b>Disclosure:</b> Dr. Al Robaidi has nothing to disclose.
