The newborn period poses the most vulnerable time in the development of epileptic seizures. The main predisposing factor is an increased neuronal excitability resulting from the incomplete maturation of a premature brain. From this point of view, premature newborns are at the highest risk of developing neonatal seizures. Early initiation of rational dia-gnostic and therapeutic intervention is often complicated by the vague or absent clinical manifestation of neonatal seizures. The variability of their clinical picture is reflected in the new draft of Neonatal Seizure Classification by International League Against Epilepsy (ILAE) from 2018. Timely dia-gnosis and initiation of adequate therapy with regard to etiology is, from the prognosis viewpoint, crucial. The strongest predictor of prognosis is etiology, as well as gestational age, initial findings during the neurological examination and ictal and interictal electroencephalographic features.

The incomplete development of the central nervous system of a newborn is a predisposing factor of increased seizure susceptibility in this age category. Primarily premature newborns are a highly endangered group. Early diagnosis of neonatal seizures, and initiation of their adequate therapy, with regard to etiology, is crucial. Seizures, especially repetitive or status epilepticus, have a negative impact on the psychomotor development of the subject, and may lead to irreversible neurological damage. The prediction of prognosis in the individual patient is based mainly on the primary cause. The past decade has shown a significant improvement in prognosis of the affected newborns. Despite the progress in diagnostics and therapy, the neonatal seizures are still linked to a high morbidity, and mortality. [ABSTRACT FROM AUTHOR]

Background: The proportion of intensive care unit (ICU) admissions in children that have and have not been directly caused by SARS-CoV-2 remains unclear. The aim of the study is to analyse a cohort of children admitted to the ICU with SARS-CoV-2 and determine whether the infection was the primary cause of their hospitalisation, a significant contributor, a suspected accomplice, or an incidental finding. Methods: This was a retrospective observational study of all the children admitted to the ICU with SARS-CoV-2 from March 2020 to February 2022 from the South Moravia region. The aim of the study was to assess whether the hospitalisation was likely to be directly caused by the virus (i.e., patients with acute COVID-19; the COVID group), whether the virus was a significant contributor to the hospitalisation (i.e., patients with multisystem inflammatory syndrome in children due to COVID-19; the MIS-C group), whether it may have contributed to the worsening of their underlying disease (the WORSENING group), or whether it was an incidental finding very likely unrelated to hospitalisation where SARS-CoV-2 positivity merely placed patients in the COVID-19 unit (the ISOLATION group). The groups were compared using a series of secondary outcomes. Results: The study population represented 150 paediatric ICU cases (age 8.6; IQR 3.5−13.3 years), with 66.7% being male. The COVID group represented 32.7% of cases (49/150); MIS-C, 30% (45/150); WORSENING, 14.7% (22/150); and ISOLATION, 22.7% (34/150). The median length of hospitalisation was found for the MIS-C group (11 days; 9 days in the ICU), the COVID group (6 days; five days in the ICU), WORSENING group (4.5 days; 4.5 days in the ICU) and the ISOLATION group (5.5 days; 3.5 days in the ICU), where the difference was significant (p < 0.001). Asymptomatic and mild cases were most common in the WORSENING (36.4% and 63.6%) and ISOLATION (52.9% and 44.1%) groups. Severe and critical cases were only present in the COVID (6.1% and 12.2%) and MIS-C (4.4% and 11.1%) groups; the severity difference was significant (p < 0.001). The groups did not differ significantly in the proportion of complete recovery and short- and long-term sequelae (p = 0.09). Conclusions: Patients with acute COVID-19 accounted for one-third of all ICU admissions, patients with MIS-C accounted for approximately another third, patients with worsening underlying disease accounted for 15%, and patients with incidental findings of SARS-CoV-2 positivity accounted for one-fifth of ICU admissions. A more significant disease was seen with acute COVID-19 and MIS-C.

This work presents a case series of four children diagnosed with severe cerebrovascular disease in association with recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, yet no patient from the group met typical diagnostic criteria for multisystem inflammatory syndrome in children. Our aim was to highlight the possible vascular involvement and coagulopathies associated with SARS-CoV-2 infection in the pediatric population. Further data are needed to better understand the pathophysiological basis of this condition in children and to ensure its optimal management., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Aim: The primary goal was to determine the yield of next-generation sequencing (NGS) epilepsy gene panels used for epilepsy etiology diagnosing using a multidisciplinary approach and to demonstrate the importance of genotype-phenotype correlations. The secondary goal was to evaluate the application of precision medicine in selected patients., Methods: This single-center retrospective study included a total of 175 patients (95 males and 80 females) aged 0-19 years. They were examined between 2015 and 2020 using an NGS epilepsy gene panel (270 genes). A bioinformatic analysis was performed including copy number variation identification. Thorough genotype-phenotype correlation was performed., Results: Out of 175 patients, described pathogenic variants or novel variants with clear pathogenic impact were identified in 30 patients (17.14%). Genotype-phenotype correlations and parental DNA analysis were performed, and genetic diagnosis was confirmed on the basis of the results in another 16 out of 175 patients (9.14%). The diagnostic yield of our study increased from 30 to 46 patients (by 53.33%) by the precise genotype-phenotype correlation., Interpretation: We emphasize a complex genotype-phenotype correlation and a multidisciplinary approach in evaluating the results of the NGS epilepsy gene panel, which enables the most accurate genetic diagnosis and correct interpretation of results., (Copyright © 2022 Elsevier Inc.
