OBJECTIVE: The association between infection and inflammatory response in singleton preterm birth (PTB) is well established, yet, less is known about PTB in twins. We aimed to compare the placental component and pregnancy outcome in pregnancies complicated with PTB of singletons vs. twin deliveries. We hypothesized that due to different underlying mechanisms, placental inflammatory lesions will be more prevalent in placentas derived from singleton pregnancies than twins. STUDY DESIGN: Labor characteristics, neonatal outcome and placental histopathology reports of spontaneous PTB at 24-33(6)/7 weeks, from 1/2008-12/2015, were reviewed...

OBJECTIVE: To investigate the relationship between the five-minute Apgar score categories (low, intermediate, and normal), mode of birth and neonatal outcomes. METHODS: This was a retrospective cross sectional study of term singleton deliveries at Mater Mothers' Hospital in Brisbane, Australia between January 2007 and December 2015. The five minute score was subdivided in to three categories - low (0-3), intermediate (4-6), and normal (≥7). These were correlated with adverse neonatal outcomes and mode of birth...

BACKGROUND: Neonatal seizures can be the first symptom of the inborn errors of metabolism. Glucose transporter type 1 deficiency syndrome (GLUT1DS) is the result of impaired glucose transport into the brain. GLUT1DS patient presents with infantile seizures with resistant to traditional seizure medications, developmental delay, acquired microcephaly, spasticity and ataxia. CASE REPORT: Here, we report a rare case of Glucose transporter type 1 deficiency syndrome caused by a different pathogenic variant in a 10-day-old neonate who presented with intractable seizures and respiratory arrest...

REVIEW
Mary Elaine Patrinos, Richard J Martin
Whereas apnea of prematurity has been well defined and its pathophysiology extensively studied, apnea in the term infant remains a greater challenge. Unfortunately, clear diagnostic criteria are lacking and pathogenesis and management vary widely. In this review we have arbitrarily organized the discussion chronologically into earlier and later postnatal periods. In the first days of life, presumed apnea may reflect physiologic events such as positional or feeding etiologies, or may be a manifestation of serious pathophysiology, such as a seizure disorder...

BACKGROUND: The association between small for gestational age (SGA; birth weight < 10(th) centile for gestational age) and neonatal morbidity is well established. Yet there is a paucity of data on the relationship between suspected SGA (sonographic estimated fetal weight <10(th) centile), at two thresholds and subsequent neonatal morbidity. OBJECTIVE: The objective of this study was to determine the relationship between sonographic estimated fetal weight (SEFW) < 5(th) centile versus 5-9(th) centile and neonatal morbidity...

Peroxisome biogenesis disorders (PBDs) represent a spectrum of human genetic disorders that are characterized by damaged peroxisome assembly. In the newborn period, the characteristics of affected patients include dysmorphic facial features, neonatal hypotonia, seizures, ocular abnormalities, poor feeding, liver cysts with hepatic dysfunction and skeletal defects. These can be caused by a defect in at least 14 different PEX genes. In this study, whole-exome sequencing (WES) was performed on samples from two Chinese newborns with clinical features of Zellweger syndrome...

BACKGROUND: Neonatal thalamic hemorrhagic stroke is related to cerebral sinus venous thrombosis and associated with neurological sequelae. Predicting factors are however lacking. METHODS: Clinical and radiological findings at onset and on follow-up of 5 neonates with thalamic hemorrhage stroke are described. RESULTS: All neonates presented with abrupt lethargy, ophistotonos, irritability and/or seizures. The thalamic hemorrhagic stroke was most often unilateral (4/5), involving the posterior/entire thalamus in 3 cases and the anterior thalamus in 2...

Using the audiogenic seizure prone Krushinsky-Molodkina rat strain, it was demonstrated that short-term (5 min) exposure of 14-day-old pups to an elevated temperature (42°C) resulted in a significant decrease in audiogenic seizure severity at the age of 1 month. Presumably, this effect is determined by the activation of the heat-shock protein system (stress proteins).

Medial ganglionic eminence (MGE) is one of the sources of inhibitory interneurons during development. Following transplantation in postnatal developing brain, MGE cells can increase local inhibition suggesting a possible protection to GABAergic dysfunction in brain disorders, such as epilepsy. Since it has been shown that MGE-derived cells harvested as neurospheres are able to suppress seizures, it might be important to investigate whether these protective effects would change in different seizure models. Here, we used pentylenetetrazole-(PTZ) and maximal electroshock (MES)-induced seizure models to test whether the transplantation of MGE cells would increase the threshold to trigger acute seizures...

Mutations in KCNQ2, encoding for subunits of potassium channels, are known to cause neonatal epileptic encephalopathy (NEE). Therapeutic options for these children are often limited. Recently, there are indications that some patients with KCNQ2 NEE show seizure response to vitamin B6 (VB6) therapy. We present a young infant with severe KCNQ2 encephalopathy resulting from a novel de novo mutation (c.1023G>C; p.(Gln341His)). In our patient, VB6 responsiveness could be demonstrated clearly by remarkable seizure-response to VB6 therapy and seizure exacerbation to discontinuation of VB6 therapy...

Non-ketotic hyperglycinemia (NKH) is a rare inborn error of metabolism and is caused by a glycine cleavage system deficiency. Eighty-five percent of patients present with the neonatal type of NKH, the infants initially develop lethargy, seizures, and episodes of apnea, and most often death. Between 60-90% of cases are caused by mutations in the glycine decarboxylase (GLDC). We believed that more mutation reports especially for rare disease as NKH help to evaluate the genotype-phenotype relationship in patients with GLDC...

Extracorporeal membrane oxygenation is used as a last resort during neonatal and pediatric resuscitation in case of refractory circulatory or respiratory failure under maximum conventional therapies. Different types of ECMO can be used depending on the initial failure. The main indications for ECMO are refractory respiratory failure (acute respiratory distress syndrome, status asthmaticus, severe pneumonia, meconium aspiration syndrome, pulmonary hypertension) and refractory circulatory failure (cardiogenic shock, septic shock, refractory cardiac arrest)...

REVIEW
Ming-Chou Chiang, Yuh-Jyh Jong, Chyi-Her Lin
Therapeutic hypothermia (TH) is a recommended regimen for newborn infants who are at or near term with evolving moderate-to-severe hypoxic ischemic encephalopathy (HIE). The Task Force of the Taiwan Child Neurology Society and the Taiwan Society of Neonatology held a joint meeting in 2015 to establish recommendations for using TH on newborn patients with HIE. Based on current evidence and experts' experiences, this review article summarizes the key points and recommendations regarding TH for newborns with HIE, including: (1) selection criteria for TH; (2) choices of method and equipment for TH; (3) TH prior to and during transport; (4) methods for temperature maintenance, monitoring, and rewarming; (5) systemic care of patients during TH, including the care of respiratory and cardiovascular systems, management of fluids, electrolytes, and nutrition, as well as sedation and drug metabolism; (6) monitoring and management of seizures; (7) neuroimaging, prognostic factors, and outcomes; and (8) adjuvant therapy for TH...

BACKGROUND: Piperacillin, in combination with tazobactam, is frequently used in infants for treating nosocomial infections, although safety data in this population are limited. Electronic health record (EHR) data can be used to evaluate drug safety in infants, but measures of drug exposure are lacking. METHODS: To relate simulated piperacillin exposure with adverse events (AEs) in infants using EHR data, we identified infants discharged from 333 neonatal intensive care units managed by the Pediatrix Medical Group between 1997 and 2012...

AIMS/HYPOTHESIS: We aimed to compare the risks of severe asphyxia-related neonatal complications in the offspring of mothers with type 1 or type 2 diabetes, and to assess the impact of maternal overweight/obesity on these risks. METHODS: This was a population-based study of 1,343,751 live-born singleton infants in Sweden between 1997 and 2011, including 5941 and 711 infants of mothers with type 1 and type 2 diabetes, respectively. ORs with 95% CIs were calculated for low Apgar score (0-6) at 5 min after birth, hypoxic ischaemic encephalopathy and neonatal seizures...

OBJECTIVE: Neonates with hypoxic-ischemic encephalopathy (HIE) managed with therapeutic hypothermia (TH) often experience acute symptomatic seizures, prompting treatment with antiseizure medications (ASMs). Because the risk of seizure occurrence after hospital discharge is unknown, the optimal ASM treatment duration is unclear. We aimed to determine the risk of seizure occurrence after hospital discharge and the impact of ASM treatment duration on this outcome. METHODS: We performed a single-center, retrospective study of consecutive neonates with HIE managed with TH who received ASMs for acute symptomatic seizures from June 2010 through December 2014...

We analyzed the KCNQ2 wild-type gene and 3 mutations to highlight the important association between the KCNQ2 phenotype and genotype. The clinical phenotypes of 3 mutations (p.E515D, p.V543 M, and p.R213Q) were compared. KCNQ2, wild-type, and mutant KCNQ2 alleles were transfected into HEK293 cells before whole-cell patch-clamp analysis. Neurodevelopmental outcomes were worst in patients with the p.R213Q mutation, better in patients with the p.E515D mutation, and best in patients with the novel p.V543 M mutation...
