Our objectives were to define the microstructural developmental trajectory of six corpus callosum subregions and identify perinatal clinical factors that influence early development of these subregions in very preterm infants. We performed a longitudinal cohort study of very preterm infants (32 weeks gestational age or younger) (N = 36) who underwent structural MRI and diffusion tensor imaging serially at four time points - before 32, 32, 38, and 52 weeks postmenstrual age. We divided the corpus callosum into six subregions, performed probabilistic tractography, and used linear mixed effects models to evaluate the influence of antecedent clinical factors on its microstructural growth trajectory...

Mammals must continuously regulate the levels of O2 and CO2 , which is particularly important for the brain. Failure to maintain adequate O2 /CO2 homeostasis has been associated with numerous disorders including sleep apnea, Rett syndrome, and sudden infant death syndrome (SIDS). But, O2 /CO2 homeostasis poses major regulatory challenges, even in the healthy brain. Neuronal activities change in a differentiated, spatially and temporally complex manner, which is reflected in equally complex changes in O2 demand...

Oxygenation instability is a very common problem in the premature infant that manifests as intermittent hypoxemia episodes (HEs). These are particularly frequent in premature infants who are on mechanical ventilation beyond the first weeks after birth. However, they can also occur in spontaneously breathing infants. Some of these episodes are due to central apnea, but in ventilated infants, they are frequently due to contractions of the abdominal musculature that can splint the respiratory pump, resulting in periods of decreased lung volume and hypoventilation...

Intracranial hemorrhage is an important cause of brain injury in the neonatal population and bedside percutaneous needle aspiration has emerged as an alternative due to the major risks that can be caused by standard neurosurgical decompression. We aimed to assess the effectiveness of this minimally invasive bedside technique and conducted a retrospective analysis of all newborn infants with a large extra-axial hemorrhage associated with a parenchymal hemorrhage causing a midline shift, managed at three academic centers over a 15-year period...

BACKGROUND: Infants and children with syndromic craniosynostosis (SCS), such as Apert-, Crouzon- or Pfeiffer syndrome, are prone to sleep disordered breathing (SDB) including obstructive sleep apnea and upper airway resistance syndrome (OSAS, UARS), potentially leading to tracheostomy. We modified the Tübingen Palatal Plate (TPP), an oral appliance with a velar extension effectively treating airway obstruction in Robin sequence, by attaching a tube to its velar extension to bridge the narrow pharyngeal airway in SCS patients...

BACKGROUND: Postoperatively, young infants are admitted overnight in view of the risk for respiratory complications such as desaturation and apnea. This risk seems much lower than previously reported. Until what age this risk persists, and which infants might actually qualify for day-care treatment, is unknown. METHODS: We retrospectively reviewed medical charts from preterm infants <45 weeks postconceptional age (PCA), 45-60 weeks PCA, and term infants <3 months admitted overnight after inguinal hernia repair, from January 2011 to December 2015 in a large tertiary children's hospital...

BACKGROUND AND OBJECTIVES: Caffeine is effective in the treatment of apnea of prematurity. Although caffeine therapy has a benefit on gross motor skills in school-aged children, effects on neurobehavioral outcomes are not fully understood. We aimed to investigate effects of neonatal caffeine therapy in very low birth weight (500-1250 g) infants on neurobehavioral outcomes in 11-year-old participants of the Caffeine for Apnea of Prematurity trial. METHODS: Thirteen academic hospitals in Canada, Australia, Great Britain, and Sweden participated in this part of the 11-year follow-up of the double-blind, randomized, placebo-controlled trial...

Caffeine is the most frequently used medication in premature infants. It is the respiratory stimulant of choice for apnea associated with prematurity and has been called the silver bullet in neonatology because of many proven benefits and few known risks. Research has revealed that sedative/anesthetic drugs trigger apoptotic death of neurons and oligodendrocytes in developing mammalian brains. Here we evaluated the influence of caffeine on the neurotoxicity of anesthesia in developing nonhuman primate brains...

Among inpatients suffering from bronchiolitis, approximately a quarter may undergo a prolonged length of stay (LOS) for the treatment of their respiratory condition. However, there have been few research studies that have evaluated variables that may be associated with a prolonged LOS in these patients, especially in low-income and middle-income countries, where the clinical and economic burden of the disease is the greatest. In an analytical single-center cross-sectional study, we included a population of patients with acute bronchiolitis hospitalized between March and June 2016...

OBJECTIVE Chiari malformation type II (CM-II) in myelomeningocele is associated with a significant rate of mortality and poor outcome. Death is frequently heralded by the onset or progression of neurological symptoms. The authors sought to identify predictors of poor outcome and mortality within the myelomeningocele population at Children's Hospital of Pittsburgh. METHODS A retrospective chart and radiology review was performed on all infants who underwent primary closure of a myelomeningocele defect at Children's Hospital of Pittsburgh between the years of 1995 and 2015...

Apnea of prematurity (AOP) is one of the most common diagnoses in preterm infants. Severe and recurrent apneas are associated with cerebral injury and adverse neurodevelopmental outcome. Despite pharmacotherapy and respiratory support to prevent apneas, a proportion of infants continue to have apneas and often need tactile stimulation, mask, and bag ventilation and/or extra oxygen. The duration of the apnea and the concomitant hypoxia and bradycardia depends on the response time of the nurse. We systematically reviewed the literature with the aim of providing an overview of what is known about the effect of manual and mechanical tactile stimulation on AOP...

Continuous positive airway pressure (CPAP) is being increasingly used in children of all age ranges. The limited number of commercially available masks especially in infants and young children may complicate its use and compliance. In this report, we describe our experience with the use of the Optiflow™ (Fisher and Paykel Healthcare) Nasal Cannula attached to a regular CPAP device in the setting of chronic CPAP use. This interface consists of a nasal cannula and was originally designed for the delivery of high-flow oxygen therapy...
