During the Zika epidemic in Brazil, a baby was born at term with microcephaly and arthrogryposis. The mother had Zika symptoms at 10 weeks of gestation. At 17 weeks, ultrasound showed cerebral malformation and ventriculomegaly. At 24 weeks, the amniotic fluid contained ZIKV RNA and at birth, placenta and maternal blood were also positive using RT-qPCR. At birth the baby urine contained ZIKV RNA, whereas CSF at birth and urine at 17 days did not. Seizures started at 6 days. EEG was abnormal and CT scan showed cerebral atrophy, calcifications, lissencephaly, ventriculomegaly, and cerebellar hypoplasia...

PURPOSE OF REVIEW: Caffeine use in preterm infants has endured several paradigms: from standard of care to possible neurotoxin to one of the few medications for which there is evidence of bronchopulmonary dysplasia (BPD) risk reduction. The purpose of the review is to analyze this dynamic trajectory and discuss controversies that still remain after decades of caffeine use. RECENT FINDINGS: Following concerns for caffeine safety in preterm infants, a large randomized controlled trial demonstrated a reduction in BPD and treatment for patent ductus arteriosus...

PURPOSE OF REVIEW: Continuous glucose monitoring (CGM) is increasingly used in the management of diabetes in children and adults, but there are few data regarding its use in neonates. The purpose of this article is to discuss the potential benefits and limitations of CGM in neonates. RECENT FINDINGS: Smaller electrodes in new sensors and real-time monitoring have made CGM devices more approachable for neonatal care. CGM is well tolerated in infants including very low birth weight babies, and few if any local complications have been reported...

PURPOSE OF REVIEW: The rapid progress in biomarker science is on the threshold of significantly changing clinical care for infants in the neonatal ICU. Infants with neonatal brain injuries will likely be the first group whose management is dramatically altered with point-of-care, rapidly available brain biomarker analysis. Providing an interim update on progress in this area is the purpose of this review. RECENT FINDINGS: Highlighted findings from the past 18 months of publications on biomarkers in neonatal brain injury include; Specific nonbrain markers of cardiac health and global asphyxia continue to provide information on brain injury after hypoxic-ischemic encephalopathy (HIE)...

Supplemental oxygen given to preterm infants has been associated with permanently altering postnatal lung development. Now that these individuals are reaching adulthood, there is growing concern that early-life oxygen exposure may also promote cardiovascular disease through poorly understood mechanisms. We previously reported that adult mice exposed to 100% oxygen between postnatal days 0-4 develop pulmonary hypertension defined pathologically by capillary rarefaction, dilation of arterioles and veins, cardiac failure, and a reduced lifespan...

Pulmonary hypertension (PH) complicating bronchopulmonary dysplasia (BPD) worsens clinical outcomes in former preterm infants. Increased serotonin (5-hydroxytryptamine, 5-HT) signaling plays a prominent role in PH pathogenesis and progression in adults. We hypothesized that increased 5-HT signaling contributes to the pathogenesis of neonatal PH complicating BPD and neonatal lung injury. Thus, we interrogated 5-HT signaling in neonatal mice exposed to bleomycin, previously demonstrated to induce PH and alveolar simplification...

Probiotics are used in the prophylaxis and treatment of several conditions, including irritable bowel syndrome, diarrhoea, necrotising enterocolitis (NEC) and colic in infants. Despite the long history of probiotic use in humans, there is still significant debate about their efficacy and safety, particularly in HIV-infected and immunocompromised individuals. Here, we reviewed the safety and adverse event (AE) reporting from clinical trials that have tested probiotics in at risk populations, including HIV-infected individuals, the terminally ill and elderly, and neonates...

Neuro-axial anesthesia has been the preferred technique for inguinal hernia repair when attempting to avoid general anesthesia in neonates and preterm infants. We present a case where an erector spinae plane block was used successfully for this surgery. Hemodynamic stability, minimal anesthetic requirements, and excellent pain control were documented. This block promises to be a valuable and safe alternative for inguinal hernia repair, accompanying the path of neuroprotective anesthesia.

As perinatal and postnatal care of neonates with impaired kidney function is constantly improving, the number of infants needing renal replacement therapy is increasing. Consequently, the general attitude of clinicians to offer renal replacement therapy (RRT) during the first year of life is changing gradually. The ideal renal replacement modality for children and adolescents is renal transplantation (RTX), as both the short-term and long-term medical complications of hemo- and peritoneal dialysis confer inferior survival rates compared to RTX to this patent group...

Meconium-stained amniotic fluid (MSAF) during delivery is a marker of fetal stress. Neonates born through MSAF often need resuscitation and are at risk of meconium aspiration syndrome (MAS), air leaks, hypoxic-ischemic encephalopathy, extracorporeal membrane oxygenation (ECMO), and death. The neonatal resuscitation approach to MSAF has evolved over the last three decades. Previously, nonvigorous neonates soon after delivery were suctioned under the vocal cords with direct visualization technique using a meconium aspirator...

Glutathione synthetase deficiency (GSSD) is a rare inborn error of glutathione metabolism with autosomal recessive inheritance. The severe form of the disease is characterized by acute metabolic acidosis, usually present in the neonatal period with hemolytic anemia and progressive encephalopathy. A case of a male newborn infant who had severe metabolic acidosis with high anion gap, hemolytic anemia, and hyperbilirubinemia is reported. A high level of 5-oxoproline was detected in his urine and a diagnosis of generalized GSSD was made...

Escherichia coli K1 strains are major causative agents of invasive disease of the new born. The age dependency of infection can be reproduced in the neonatal rat. Colonization of the small intestine following oral administration of K1 bacteria leads rapidly to invasion of the blood circulation; bacteria that avoid capture by the mesenteric lymphatic system and evade antibacterial mechanisms in the blood may disseminate to cause organ-specific infections such as meningitis. Some E. coli K1 surface constituents, in particular the polysialic acid capsule, are known to contribute to invasive potential but a comprehensive picture of the factors that determine the fully virulent phenotype has not so far emerged...

Congenital diaphragmatic hernia (CDH) is a severe congenital anomaly which impairs normal pulmonary development leading to acute and chronic respiratory failure, pulmonary hypoplasia, pulmonary hypertension, and mortality. CDH is the most common non-cardiac indication for neonatal ECMO. Prenatal and postnatal predictors of CDH severity aid in patient selection. Centers vary in preferred mode of ECMO and timing of CDH repair. Survivors of severe CDH with ECMO are at risk for long-term sequelae including neurodevelopmental delays...
