Hyperbilirubinemia (HB) occurs in 90% of preterm newborns. Moderate HB can induce acute neurological disorders while severe HB has been linked to a higher incidence of apneas of prematurity. The present study aimed to test the hypothesis that even moderate HB disrupts cardiorespiratory control in preterm lambs. Two groups of preterm lambs (born 14 days prior to term), namely control (n = 6) and HB (n = 5), were studied. At day 5 of life, moderate HB (150-250 μmol/L) was induced during 17 h in the HB group after which cardiorespiratory control as well as laryngeal and pulmonary chemoreflexes were assessed during baseline recordings and during hypoxia...

BACKGROUND: Anxiety is a concern in obstetrics, especially in preeclamptic mothers. Sedation is not commonly used in parturients for fear of adverse neonatal effect. We investigated maternal and neonatal outcome of midazolam as an adjuvant to spinal anesthesia for elective cesarean delivery. METHODS: A prospective randomized controlled trial, in which eighty preeclamptic parturients received either an intravenous dose of 0.035 mg/kg of midazolam or an equal volume of normal saline, 30 min before spinal anesthesia...

High doses of micafungin are advocated in neonates with systemic candidiasis but limited pharmacokinetic (PK) and safety data are available to support their use. Eighteen preterm neonates and infants with systemic candidiasis, 3 with meningitis, were treated for at least 14 days with 8 to 15 mg/kg/day of intravenous micafungin. Plasma concentrations (4 measurements) were determined after the third dose and cerebrospinal-fluid (CSF) concentrations were also obtained in three patients. Population PK analyses were used to identify the optimal model and further validated using external data (n=5)...

BACKGROUND: Commonly used general anesthetics are considered to be neurotoxic to the developing rodent brain, leading to poor long-term outcome. However, it is unclear whether these rodent studies can be extrapolated to the human neonate. Given that anesthesia for urgent neonatal surgery cannot be avoided, it is vitally important to assess other factors that may impact neurological outcome following anesthesia and surgery. OBJECTIVE: The purpose of this study is to identify thresholds for detecting vital sign deviations, which may have the potential for affecting neurological outcome following anesthesia and surgery in neonates...

BACKGROUND: Chorioamnionitis is a leading cause of perinatal morbidity and mortality. Amnioinfusion aims at reducing the adverse effects of chorioamnionitis by dilution of the infective organisms or by an anti-microbial effect of the fluid infused. OBJECTIVES: The objective of this review was to determine the effect of amnioinfusion on clinical and sub-clinical chorioamnionitis, fetal well-being, fetal heart rate characteristics and perinatal and maternal morbidity and mortality...

OBJECTIVES: Mutations in KCNJ11 are the most common cause of permanent neonatal diabetes mellitus (NDM). Approximately 25% of patients have obvious neurological dysfunction, but whether milder related problems might be more common has been unclear. We sought to assess the prevalence of parental concerns about learning, behavior, attention deficit hyperactivity disorder (ADHD), social competency, and sleep in subjects with KCNJ11-related NDM compared to unaffected sibling controls. STUDY DESIGN: Subjects or their guardians in the University of Chicago Monogenic Diabetes Registry completed a survey examining learning, behavior, ADHD and sleep...

OBJECTIVE: Vein of Galen aneurysmal malformation (VGAM) is a rare anomaly in which an adequate perinatal management may warrant good neurological outcome. However, most fetal series are too scant to allow reliable statistical assessment of poor prognostic factors. Aim of this paper is to assess, in a two-center series of 49 cases, the prognostic value of several prenatal variables. The primary endpoint of the analysis is to identify possible prenatal indicators of poor outcome, in terms of mortality and cerebral disabilities...

BACKGROUND: Although sucrose is most extensively examined for its analgesia effect on a single procedural pain, neonates in neonatal intensive care units can be exposed to numerous painful procedures every day requiring multiple doses of sucrose. Some experiments have been performed to examine the efficacy and safety of repeated sucrose administration for repeated procedural pain; however, a systematic review of this topic has not yet been carried out. OBJECTIVE: To identify and assess the evidence demonstrating the efficacy and safety of repeated sucrose for repeated procedural pain in neonates...

AIM: Having observed slow pupillary light responses (PLR) in infants at high risk of cerebral palsy, we retrospectively evaluated whether these were associated with specific brain lesions or unfavourable outcomes. METHODS: We carried out neurological examinations on 30 infants at very high risk of cerebral palsy five times until the corrected age of 21 months, classifying each PLR assessment as normal or slow. The predominant reaction during development was determined for each infant...

Extracorporeal membrane oxygenation (ECMO) has been increasingly used to rescue neonates and children with cardiac and/or respiratory failure, and critical illnesses including pulmonary artery hypertension (PAH) unresponsive to conventional therapies. This study assesses mortality and outcomes in neonates and children with PAH supported with ECMO.Neonates and children from the 2012 HCUP Kids' Database were identified using ICD-9codes. Children with congenital heart disease were excluded. Univariate logistic regression was applied to assess the relationship between ECMO and outcomes using matched cohorts for age, elective admission and Elixhauser comorbidity score...

BACKGROUND: The morbidity and mortality rates due to cardiovascular events such as myocardial infarction are known to exhibit seasonal variations. Moreover, changes in the ambient temperature are reportedly associated with an increase in these events, which may potentially involve blood coagulation markers. Bleeding due to vitamin K deficiency in neonates, which is associated with high mortality and a high frequency of neurological sequelae, is more commonly observed during the summer season and in warm regions in Japan...
