Background Cerebellar hemorrhage is a complication of extreme prematurity with a significant impact on the neurodevelopmental outcome. It has been shown that cerebellar hemorrhage is associated with a reduction in the anteroposterior diameter of the pons on the midline sagittal plane at term-equivalent age, suggesting that cerebellar injury may...

BACKGROUND AND PURPOSE: The anatomy of the deep venous system is characterized by a great variability that might play an important role in the pathogenesis of brain lesions in the preterm brain. The aim of this study was to compare the anatomy of cerebral subependymal veins evaluated on SWI venography in 3 groups of neonates with normal brain...

Objective To assess diagnostic accuracy of cranial ultrasound (CUS) performed through the anterior fontanelle (AF) and mastoid fontanelle (MF) in detecting cerebellar haemorrhages (CBH) in very low birthweight (VLBW) infants. Setting Third-level neonatal intensive care unit (NICU). Design VLBW infants consecutively admitted at Gaslini...

In recent decades, there has been a general increase in survival rates of preterm and low birth weight infants, but this overall decrease in perinatal mortality has not been accompanied by a decrease in long-term physical and mental disability. In order to reduce the long-term sequelae of prematurity and to establish preventive measures, it is...

Objective: Many neonatal intensive care units (NICUs) have adopted the practice of performing routine brain MRI in very low birth weight (VLBW) infants at term-equivalent age in order to better evaluate prematurity-related acquired lesions. A number of unexpected brain abnormalities of potential clinical significance can be visualised on...

Objective: To assess diagnostic accuracy of cranial ultrasonography (CUS) in detecting low-grade (i.e. grade I and grade II) germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) in very low birth weight (VLBW) infants.Methods: Among VLBW infants who were admitted to Gaslini Childrens Hospital neonatal intensive care unit between...

Anticoagulation in a neonate is a challenge and the availability of anticoagulant options is extremely limited. Here we describe the use of a direct thrombin inhibitor, bivalirudin, in a full-term neonate with symptomatic cerebral sinovenous thrombosis complicated by bilateral thalamic hemorrhagic stroke and intraventricular hemorrhage, who...

Aim: Punctate white matter lesions (PWML) are frequently detected in preterm infants undergoing brain MRI at term equivalent age (TEA). The aims of this study were to assess prevalence of PWML and to identify risk factors for PWML in VLBW infants. Methods: Brain MRI scans obtained at TEA and clinical charts of a consecutive sample of very low...

Objectives: To evaluate punctate white matter lesion (PWML) influence in preterm infants on the long-term neurodevelopmental outcome (NDO). Methods: PubMed and EMBASE were searched from January 1, 2000, to May 31, 2021. Studies were included in which PWML in preterm infants on MRI around term-equivalent age (TEA) and NDO at ≥12 months were...

Background and purpose The anatomy of the deep venous system plays an important role in the pathogenesis of brain lesions in the preterm brain as shown by different histological studies. The aims of this study were to compare the subependymal vein anatomy of preterm neonates with germinal matrix haemorrhage–intraventricular haemorrhage...

The risk of oxidative stress is high in preterm newborns. Room air exposure of an organism primed to develop in a hypoxic environment, lacking antioxidant defenses, and subjected to hyperoxia, hypoxia, and ischemia challenges the newborn with oxidative stress production. Free radicals can be generated by a multitude of other mechanisms, such as...

Objective: Prenatal features of isolated cerebellar haemorrhagic lesions have not been sufficiently characterised. We aimed to better define their MR imaging characteristics, documenting the location, extension, evolution stage and anatomic sequelae, and to better understand cerebellar haemorrhage pathophysiology. Materials and methods: We...

Neonatal hypoglycemia is a common condition. A transient reduction in blood glucose values is part of a transitional metabolic adaptation following birth, which resolves within the first 48 to 72 h of life. In addition, several factors may interfere with glucose homeostasis, especially in case of limited metabolic stores or increased energy...

Background: Early exposure to nociceptive events may cause brain structural alterations in preterm neonates, with long-lasting consequences on neurodevelopmental outcome. Little is known on the extent to which early pain may affect brain connectivity. We aim to evaluate brain functional connectivity changes in preterm neonate that underwent...

Placental pathology as a predisposing factor to intraventricular hemorrhage remains a matter of debate, and its contribution to cerebellar hemorrhage development is still largely unexplored. Our study aimed to assess placental and perinatal risk factors for intraventricular and cerebellar hemorrhages in preterm infants. This retrospective...

Background: Postnatal insulin-like growth factor-1 (IGF-1) replacement with recombinant human (rh)IGF-1 and IGF binding protein-3 (rhIGF-1/rhIGFBP-3) is being studied as a potential treatment to reduce comorbidities of prematurity. We have recently reported on a phase II, multicenter, randomized, controlled trial comparing postnatal...

Aim: To determine whether isolated low-grade germinal matrix-intraventricular haemorrhages (LG-GMH-IVH) and low-grade punctate cerebellar haemorrhages (LG-CBH) contribute to the neurodevelopment of infants born preterm with very low birthweight (VLBW). Method: A prospective observational cohort study was conducted on infants born with VLBW...
