The investigation was conducted to reveal reliable echographic features of early (necrotic) stages of periventricular leukomalacia (PVL) on the basis of retrospective analysis of echograms of decreased children (with postmortem diagnosis of PVL) and survived newborns with pronounced cystic changes in the periventricular areas (advanced PVL stage), which were revealed during dynamic echoencephalography. Altogether 268 echograms of 78 children with a birth-weight from 700 to 2400 g were analysed. All children but one were born preterm. Ultrasound device "Aloka-SSD 118" (Japan), with a transducer frequency of 5mHz, was used during frontal fontanel echoencephalography. Three patterns of echographic image of periventricular areas compromised with the aforementioned disease were identified. In the detection of early PVL stages, the specificity of the technique was 94% and sensitivity, 86%. The followup that lasted from 9 months to 2.5 years revealed varying pronounced neurologic disorders in all the survived children with PVL.

However, even with advances in care for critically ill newborns, BPD continues to be a challenge for the care team and family members. This has been identified as one of the most important causes of morbidity and mortality due to prematurity, and can have significant impacts on the quality of life of the affected patients.

Objective: To compare adverse neonatal outcomes between trial of vaginal delivery and upfront cesarean delivery for singleton infants born at 24 to 28 weeks of gestation.
Methods: This is a retrospective cohort study that was conducted at a university-affiliated tertiary medical center between 2011 and 2022, involving singleton pregnancies delivered between 24 and 27 weeks of gestation. Participants were divided into two groups based on their intended mode of delivery: a trial of labor (TOL) group and an upfront cesarean delivery (CD) group.

The limit of periviability is constantly changing as infants born at 22-25 weeks of gestation increasingly survive. The data from our region are limited due to the small numbers of these infants among the NICU population. In this study, we evaluated the survival rates and short-term outcomes among preterm neonates between 22 and 24 weeks of gestation admitted to Tawam Hospital, United Arab Emirates.
