Hypoxic-ischemic brain injury occurring in antenatal, perinatal or early postnatal period constitutes an important diagnostic problem in both term and prematurely born neonates. Over the past several years magnetic resonance imaging (MRI) has become relatively easily accessible in Poland. On the basis of the central nervous system MRI, the experienced radiologist are able to determine the location of the hypoxic-ischemic lesions, their extent and evolution. Therefore he can help clinicians to answer the question whether the brain damage of the newborn is responsible for its clinical condition and he can contribute to determining the prognosis of the infant's future development. The aim of this study is to present the current knowledge of different types of hypoxic-ischemic brain lesions based on our personal experience and MR images from the archives of the Department of Diagnostic Imaging at the Institute of Mother and Child.

Neurosonography (NSG) is pivotal for rapid, point-of-care neonatal brain assessment. This review elucidates the comprehensive applications of NSG in pediatric care, emphasizing its role in early diagnosis and management of pathologies affecting the pediatric head-such as scalp lesions, misshapen calvarium, ventricular distortions, and cerebrovascular abnormalities, and its specific role in conditions like hypoxic-ischaemic encephalopathy (HIE) across different neonatal gestational ages. We explore its diagnostic advantage in critical care settings, particularly for infants with stroke risk in sickle cell disease, ECMO-related complications, screening for therapeutic hypothermia, and routine neonatal intensive care unit monitoring.

Objective: Hypoxic-ischemic brain damage (HIBD) is a leading cause of neonatal mortality, resulting in brain injury and persistent seizures that can last into the late neonatal period and beyond. Effective treatments and interventions for infants affected by hypoxia-ischemia remain lacking. Clinical investigations have indicated an elevation of nuclear factor of activated T cells 5 (NFAT5) in whole blood from umbilical cords of severely affected HIBD infants with epilepsy.

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that certain of the TUNEL assay data shown in Fig. 4B were strikingly similar to data appearing in different form in another article written by different authors at different research institutes that had already been submitted for publication to the journal (which has subsequently been retracted). Owing to the fact that these contentious data had already apparently been submitted for publication prior to the receipt of this paper to , the Editor has decided that this paper should be retracted from the Journal.

Second stage of labor is considered to be associated with an increased risk of intrapartum fetal hypoxic injury. This is due to a combination of several risk factors such as -the increased frequency, strength and duration of uterine contractions due to higher number and affinity of myometrial oxytocin receptors; -the Ferguson's reflex which leads to a reflex release of endogenous oxytocin in response of the distension of the cervix by descending fetal head in late stages of labor; maternal expulsive efforts with the Valsalva manoeuvre that may reduce maternal oxygenation, as well as reduce the venous return and maternal cardiac output due to increased intrathoracic pressure, winch may lead to reduced placental oxygenation; - and increased fetal intracranial pressure due to head compression leading to a potential decrease in fetal cerebral oxygenation. In addition, the umbilical cord often forms one or more loops around the fetal neck, which may get tightened as the head descends leading to an acute and intermittent cessation of fetal oxygenation.

In term neonates with hypoxic-ischemic encephalopathy (HIE), cerebellar injury is becoming more and more acknowledged. Animal studies demonstrated that Purkinje cells (PCs) are especially vulnerable for hypoxic-ischemic injury. In neonates, however, the extent and pattern of PC injury has not been investigated.
