We analyzed clinical and instrumental data of 403 consecutive newborns with gestational age from 24 to 32 weeks, admitted to the University-Hospital of Parma between January 2000 and December 2007, to evaluate the possible relationship between neonatal mortality and occurrence of neonatal seizures in very preterm newborns. Seventy-four subjects died during hospital stay. Seizures were present in 35 neonates, in whom the mortality rate was 37.1%. Multivariate analysis revealed that birth-weight <1000 g (odds ratio: 4.48; 95% confidence interval: 1.47-13.68; P < .01), cardiopulmonary resuscitation (odds ratio: 5.35; 95% confidence interval: 1.19-23.98; P = .02), and moderately and severely abnormal cerebral ultrasound scan findings (odds ratio: 2.48; 95% confidence interval: 1.02-6.05; P < .04; odds ratio: 9.56; 95% confidence interval: 3.45-26.51; P < .01, respectively) were related to the in-hospital mortality but not the presence of neonatal seizures. Our study suggests that neonatal seizures alone are not an independent risk factor for early death in very preterm newborns.

Outcomes following deep hypothermic circulatory arrest versus antegrade cerebral perfusion during aortic arch reconstruction.
JTCVS Open
December 2024
Division of Cardiothoracic Surgery, Department of Surgery, School of Medicine, The University of Alabama at Birmingham, Birmingham, Ala.
Objective: The optimal method for cerebral protection during aortic arch reconstruction in neonates and infants is unknown. We compare the outcomes of deep hypothermic circulatory arrest and selective antegrade cerebral perfusion strategies in neonatal and infant cardiac surgery.
Methods: We retrospectively identified all patients aged less than 1 year who underwent aortic arch reconstruction from 2012 to 2023.
Scaling convolutional neural networks achieves expert level seizure detection in neonatal EEG.

Neonatal seizures require urgent treatment, but often go undetected without expert EEG monitoring. We have developed and validated a seizure detection model using retrospective EEG data from 332 neonates. A convolutional neural network was trained and tested on over 50,000 hours (n = 202) of annotated single-channel EEG containing 12,402 seizure events.

Objective: To explore the genetic characteristics of a Chinese pedigree with rare mosaic 11q partial duplication and its pathogenetic mechanisms.
Methods: A pedigree which underwent prenatal diagnosis at Wenzhou Central Hospital between September 25, 2015 and November 30, 2023 was selected for the study. Clinical data were collected from the pedigree.
Neonatal encephalopathy: when the diagnosis is not hypoxic ischaemic encephalopathy.
Arch Dis Child Educ Pract Ed
January 2025
Paediatric Neurology, Oxford University Hospitals NHS Foundation Trust, Oxford, UK.
Neonatal encephalopathy (NE) presents as reduced consciousness, often with seizures, abnormal tone, feeding and respiratory difficulties. The most common cause is secondary to a hypoxic-ischaemic event. However, there are many important diagnoses that can also present as NE, so-called 'hypoxic ischaemic encephalopathy (HIE) mimics'.

This case report details a neonate presenting with central apnea, profound hypotonia, and refractory seizures, alongside prenatal findings of polyhydramnios and hiccup-like fetal movements, all strongly suggestive of severe NKH. Diagnostic evaluation confirmed markedly elevated glycine levels in serum and CSF, with a CSF-to-plasma glycine ratio exceeding 0.
