Small remnants of the right valve of the sinus venosus are commonly found in adults, but the incidence and risk associated with these embryonic remnants in neonates are not well studied. The following report describes a cyanotic neonate with a large Eustachian valve remnant creating a functional cor triatriatum dexter who was initially diagnosed with persistent pulmonary hypertension of the newborn. The cyanosis in this infant improved over the first postnatal week with conservative management, but she suffered multifocal subcortical stroke, likely related to her intracardiac shunt...

BACKGROUND: Levels or fluctuations in the partial pressure of CO2 (PCO2) may affect outcomes for extremely low birth weight infants. OBJECTIVES: In an exploratory analysis of a randomized trial, we hypothesized that the PCO2 values achieved could be related to significant outcomes. METHODS: On each treatment day, infants were divided into 4 groups: relative hypocapnia, normocapnia, hypercapnia, or fluctuating PCO2. Ultimate assignment to a group for the purpose of this analysis was made according to the group in which an infant spent the most days...

BACKGROUND: After neonatal asphyxia, therapeutic hypothermia (HT) is the only proven treatment option. Although established as a neuroprotective therapy, benefit from HT has been questioned when infection is a comorbidity to hypoxic-ischaemic (HI) brain injury. Gram-negative and gram-positive species activate the immune system through different pathogen recognition receptors and subsequent immunological systems. In rodent models, gram-negative (lipopolysaccharide [LPS]) and gram-positive (PAM3CSK4 [PAM]) inflammation similarly increase neuronal vulnerability to HI...

OBJECTIVES: Providing parenteral amino acids to very-low-birth-weight infants during the first weeks of life is critical for adequate growth and neurodevelopment. However, there is no consensus about what dose is appropriate or when to initiate supplementation. As a result, daily practice varies among neonatal intensive care units. The objective of our study was to determine the effects of early parenteral amino-acid supplementation (within 24 h of birth) versus later initiation and high dose (>3...

BACKGROUND: Gastro-oesophageal reflux (GOR) and apnoea are common in infants; whether there is a causal relationship is controversial. OBJECTIVES: To determine whether there was a temporal relationship between GOR and apnoea, in particular, the frequency of obstructive apnoeas and if the frequency of GOR episodes correlated with apnoea frequency when maturity at testing was taken into account. METHODS: Polysomnography and pH/multichannel intraluminal impedance (MII) studies were performed...

BACKGROUND: Prophylactic indomethacin reduces the risk of severe intraventricular hemorrhage (IVH) but does not reduce death or neurodevelopmental impairment (NDI) among extremely low birth weight (ELBW) infants. Some investigators have suggested that prophylactic indomethacin may have a greater treatment effect on severe IVH among infants at high risk for severe IVH. OBJECTIVE: To determine whether the relative treatment effects of prophylactic indomethacin on severe IVH and the composite outcome of death or NDI vary based on the risk of severe IVH...

The epidemic of Zika virus (ZIKV) has resulted in a surge of newborns with microcephaly and brain abnormalities. In this report, we describe the first case, to our knowledge, of congenital Zika syndrome with concomitant critical congenital heart disease. The mother had a confirmed ZIKV infection in the first trimester of pregnancy. Fetal ultrasonography at 31 weeks of gestation revealed cerebral cortical calcifications and hypoplastic left heart syndrome. The severity of brain involvement was assessed by postnatal magnetic resonance imaging and echocardiogram, and palliative surgery was performed...

Michael Obladen
Since antiquity, cot death has been explained as accidental suffocation, overlaying, or smothering. Parents were blamed for neglect or drunkenness. A cage called arcuccio was invented around 1570 to protect the sleeping infant. Up to the 19th century, accidents were registered as natural causes of death. From 1830, accidental suffocation became unacceptable for physicians and legislators, and "natural" explanations for the catastrophe were sought, with parents being consoled rather than blamed. Two assumed causes had serious consequences: thymus hyperplasia was irradiated, causing thyroid cancer, and the concept of central apnea was widely accepted, which led to home monitors and distracted from epidemiological evidence...

BACKGROUND: Necrotizing enterocolitis (NEC) is a serious complication of prematurity. Currently, there is limited evidence to guide investigation and treatment strategies. OBJECTIVES: To evaluate the parameters used to diagnose or exclude NEC, and to identify differences between neonatologists and pediatric surgeons. METHODS: A scenario-based survey was sent to neonatologists and pediatric surgeons. RESULTS: 173 physicians from 26 countries completed the survey (55% neonatologists and 45% pediatric surgeons)...

Studies using videotape recordings and respiratory function monitoring have shown that both face mask (FM) application and endotracheal tube (ETT) placement represent a challenge for resuscitators. Hence, there is a strong need for devices that can largely be used independently of individual operator training levels, in order to ensure more reliable support in time-critical situations, such as neonatal resuscitation. The laryngeal mask airway device (LMA) has evolved as a potentially very valuable tool. We conducted a systematic review of studies evaluating the use of the LMA in neonatal resuscitation...

BACKGROUND: The immature fragile skin of preterm infants represents an inadequate protective barrier. The emollient and anti-infective properties of coconut oil make it a potentially beneficial topical agent for this population. OBJECTIVES: Our aim was to evaluate feasibility, safety, and the effects of topical coconut oil on skin condition in very preterm infants. METHODS: An open-label randomised controlled trial in preterm infants <30 weeks' gestation was conducted...

BACKGROUND: Treatment of apnea is highly dependent on the type of apnea. Chest impedance (CI) has inaccuracies in monitoring respiration, which compromises accurate apnea classification. Electrical activity of the diaphragm measured by transcutaneous electromyography (EMG) is feasible in preterm infants and might improve the accuracy of apnea classification. OBJECTIVES: To compare the accuracy of apnea classification based on diaphragmatic EMG (dEMG) and CI tracings in preterm infants...

BACKGROUND: Despite the critical importance of breast milk for preterm and sick neonates, there is no consensus regarding the use of raw mother's own milk (MOM) in neonatal units. OBJECTIVES: This study aimed to describe the use of raw MOM in hospitalised neonates before day 7 (early use), and to investigate: (i) related factors, (ii) maternal satisfaction, and (iii) the association with breastfeeding continuation. METHODS: This prospective cohort included 516 neonates intended to be breastfed in 2 French neonatal units...

BACKGROUND: A new pattern of bronchopulmonary dysplasia (BPD) has emerged with the improved survival of preterm children. OBJECTIVES: Our aim was to characterize structural abnormalities associated with new BPD and to evaluate whether the severity of high-resolution computed tomography (HRCT) changes is associated with lung function. METHODS: HRCT scans were performed on 21 schoolchildren with a history of new BPD (mild, n = 9; moderate, n = 4; and severe, n = 8) with a mean age of 12...

BACKGROUND: Phenobarbitone (PB) is the first-line anti-convulsant for neonatal seizures. The use of peritoneal dialysis (PD) to enhance drug elimination in cases of neonatal PB overdose has not been reported. OBJECTIVE: To report a case of neonatal severe PB toxicity and review the elimination of PB by PD. METHODS: Assessment of PD drug clearance. RESULTS: A neonate with prolonged seizures was administered PB. Encephalopathy and myocardial failure developed, which were initially suspected to be secondary to hypoxia...

BACKGROUND: Recent advances in magnetic resonance imaging (MRI) techniques have prompted reconsideration of the anatomical correlates of adverse outcomes in preterm infants. The importance of the contribution made by the cerebellum is now increasingly appreciated. The effect of cerebellar haemorrhage (CBH) on the microstructure of the cerebellar-cerebral circuit is largely unexplored. OBJECTIVES: To investigate the effect of CBH on the microstructure of cerebellar-cerebral connections in preterm infants aged <32 gestational weeks...

A Nicole Ferguson, Shannon C Grabich, Irene E Olsen, Rebecca Cantrell, Reese H Clark, Wendy N Ballew, Jeffrey Chou, M Louise Lawson
BACKGROUND: Clinicians have observed preterm infants in the neonatal intensive care unit growing disproportionally; however, the only growth charts that have been available were from preterm infants born in the 1950s which utilized the ponderal index. Prior to creating the recently published BMI curves, we found only 1 reference justifying the use of the ponderal index. OBJECTIVES: To determine the best measure of body proportionality for assessing growth in US preterm infants...
