BACKGROUND: Recurrent and prolonged seizures are harmful for the developing brain, emphasizing the importance of early seizure recognition and effective therapy. Amplitude-integrated electroencephalography (aEEG) has become a valuable tool to diagnose epileptic seizures, and, in parallel, genetic etiologies are increasingly being recognized, changing the paradigm of the workup and management of neonatal seizures. OBJECTIVE: To report the ictal aEEG pattern in neonates with KCNQ2-related epilepsy...

BACKGROUND: Hypophosphatasia (HPP) is a rare genetic disorder characterized by rachitic bone manifestations and a low serum alkaline phosphatase (ALP) level. It is caused by mutations in the tissue non-specific alkaline phosphatase (TNSALP) gene, which encodes the tissue non-specific isozyme of ALP. HPP patients exhibit various presentations depending on their age at onset, such as infantile HPP combined with vitamin B6-responsive seizures. CASE PRESENTATION: A newborn with infantile HPP presented with tonic convulsions from day 5 after birth and received intravenous vitamin B6 (10mg/kg/day pyridoxal phosphate)...

RATIONALE: Caffeine in the newborn period shortens the duration of assisted ventilation and reduces the incidence of bronchopulmonary dysplasia, but its effects on respiratory function in later childhood are unknown. OBJECTIVES: To determine if children born <1251 g birthweight who were treated with neonatal caffeine had improved respiratory function at 11 years of age compared with children treated with placebo. METHODS: Children enrolled in the Caffeine for Apnea of Prematurity randomized controlled trial and assessed at the Royal Women's Hospital in Melbourne at 11 years of age had expiratory flow rates measured according to the standards of the American Thoracic Society...

Apnea of prematurity (AOP) can affect even 85-100% of premature newborns and is related to lack of full maturity of organs. AOP is manifesting by 15-20 seconds cessations of breathing accompanied by bradycardia and oxygen desaturation, what can lead to hypoxia or death. Therefore it is very important to implement the effective and safe treatment immediately after birth. Widely used caffeine citrate, which stimulates the respiratory system, improving the working of the respiratory muscles. However the metabolism of caffeine citrate is difficult in preterm infants due to the immaturity of the hepatic enzyme system, what can lead to the occurrence of side effects and toxicity...

Phenobarbital is the most commonly used drug for the treatment of neonatal seizures but may induce neurodegeneration in the developing brain. Methylxanthine caffeine is used for the treatment of apnea in newborn infants and appears to be neuroprotective, as shown by antiapoptotic and anti-inflammatory effects in oxidative stress models in newborn rodents and reduced rates of cerebral palsy in human infants treated with caffeine. We hypothesized that caffeine may counteract the proapoptotic effects of phenobarbital in newborn rats...

BACKGROUND: During delivery room resuscitation of depressed newborns, provision of appropriate tidal volume (TV) with establishment of functional residual capacity (FRC) is essential for circulatory recovery. Effective positive pressure ventilation (PPV) is associated with a rapid increase in heart rate (HR). The relationship between delivery of TV and HR responses remains unclear. OBJECTIVES: The study objectives were to determine (1) the relationship between a given TV during initial PPV and HR responses of depressed newborns, and (2) the optimal delivered TV associated with a rapid increase in HR...

Placental abruption, early separation of the placenta, is associated with preterm birth and perinatal mortality, but associations with other neonatal morbidities remains under-studied. We examined the association between abruption and newborn outcomes. We analyzed n = 223,341 singleton deliveries from the Consortium on Safe Labor Study, a retrospective, multi-site, observational study (2002-2008) of electronic medical records in the U.S. Adjusted relative risks (RR), incident ratio ratios and 99% confidence intervals (CI) were estimated...

Routine mass immunization programs have contributed greatly to the control of infectious diseases and to the improvement of the health of populations. Over the last decades, the rise of antivaccination movements has threatened the advances made in this field to the point that vaccination coverage rates have decreased and outbreaks of vaccine-preventable diseases have resurfaced. One of the critical points of the immunization debate revolves around the level of risk attributable to vaccination, namely the possibility of experiencing serious and possibly irreversible adverse events...

The environment plays a critical role in shaping development and function of the brain. Stress, especially when experienced early in life, can interfere with these processes. In the context of respiratory control, perinatal stress can therefore alter the ability to achieve the "fine-tuning" necessary for proper detection of chemosensory stimuli and production of an adequate motor (respiratory) command. Depending on the timing, intensity, and duration, the detrimental consequences of perinatal exposure to adverse conditions on the respiratory network become manifest at various life stages and can persist into adulthood...

BACKGROUND: Pierre Robin sequence is characterized by mandibular retrognathia and glossoptosis resulting in airway obstruction and feeding difficulties. When conservative management fails, mandibular distraction osteogenesis or tongue-lip adhesion may be required to avoid tracheostomy. The authors' goal was to prospectively evaluate the airway and feeding outcomes of their comprehensive approach to Pierre Robin sequence, which includes conservative management, mandibular distraction osteogenesis, and tongue-lip adhesion...

Sudden demise of a healthy fetus or a neonate is a very tragic episode in the life of parents. These deaths have been a mystery since ages but still remain unexplained. This review proposes the involvement of trigeminal nerve, neurotransmitter substance P (SP), and its receptor neurokinin 1 (NK-1R) in regulation of cardiorespiratory control in fetuses and newborns. Anomalies and immaturity of neuroregulatory systems such as trigeminal system in medulla oblongata of brainstem may provide a possible mechanism of sudden perinatal deaths...

INTRODUCTION: An apnea episode is defined as the cessation of breathing for ≥15 seconds or as any suspension of breathing accompanied by hypoxia and bradycardia. Obtaining information about the respiratory system in a neonate can be accomplished using electromyography signals from the diaphragm muscle. OBJECTIVE: The purpose of this paper is to illustrate a method by which the respiratory and electrocardiographic signals from neonates can be obtained using diaphragmatic electromyography...

Caffeine is widely used for the treatment of apnea of prematurity (AoP) but whether this effect varies with sex is unknown. To shed some light on this question, we present a summary of data obtained on the effects of caffeine on the respiratory chemoreflexes and apnea frequency in 1- and 12-days old male and female rats. Caffeine was either administered as a single acute injection (10mg/kg, i.p.) or for 10 consecutive days (7.5mg/kg/day between 3 and 12days of life by gavage, simulating its clinical use). Acute caffeine had little effects on breathing in 1-day old male and female rats...

INTRODUCTION: Neonatal respiratory disorders are a leading cause of perinatal mortality due to complications resulting from premature births and prenatal exposure to drugs of abuse, but optimal treatments for these symptoms are still unclear due to a variety of confounds and risk factors. Mouse models present an opportunity to study the underlying mechanisms and efficacy of potential treatments of these conditions with controlled variables. However, measuring respiration in newborn mice is difficult and commercial components are expensive and often require modification, creating a barrier and limiting our understanding of the short and long-term effects of birth complications on respiratory function...

BACKGROUND: Caffeine is widely used to manage apnea of prematurity, and reduces the incidence of bronchopulmonary dysplasia (BPD). Deregulated transforming growth factor (TGF)-β signaling underlies arrested postnatal lung maturation in BPD. It is unclear whether caffeine impacts TGF-β signaling or postnatal lung development in affected lungs. METHODS: The impact of caffeine on TGF-β signaling in primary mouse lung fibroblasts and alveolar epithelial type II cells was assessed in vitro...

BACKGROUND The emergence of infections related to multidrug-resistant Gram-negative bacilli (MDR-GNB) reintroduced the use of colistin, an antibiotic that was previously abandoned due to adverse effects. However, because of its limited use in neonatal intensive care units, there is very little data about the effectiveness and safety of colistin in children and newborns. In this study, which will be the largest case study in the literature, we aimed to evaluate the effectiveness and safety of colistin in full-term and preterm newborns...

Congenital hyperinsulinism (CHI) is a rare condition that can cause irreversible brain damage during the neonatal period owing to the associated hypoglycemia. Hypoglycemia in CHI occurs secondary to the dysregulation of insulin secretion. CHI has been established as a genetic disorder of islet-cell hyperplasia, associated with a mutation of the ABCC8 or KCNJ11 genes, which encode the sulfonylurea receptor 1 and the inward rectifying potassium channel (Kir6.2) subunit of the ATP-sensitive potassium channel, respectively...

Mydriatic drops are routinely administered to premature neonates to screen for retinopathy of prematurity. Adverse anticholinergic side effects, particularly convulsions and tachycardia have been reported in the pediatric age group following instillation of mydriatics for diagnostic fundus examination [1, 2]. Caffeine is frequently used for apnea of prematurity. In the neonatal intensive care unit, the combined use of caffeine and mydriatic drops is a common practice. Here we report two cases of atrial arrhythmias after neonatal eye exam that improved with conservative management...
