Group B streptococcus (GBS) is a commonly recognized cause of sepsis and meningitis in neonatal and young infants. Invasive GBS infection is classified into early onset GBS disease (EOD, day 0-6), late onset GBS disease (LOD, day 7-89) and ultra late onset GBS disease (ULOD, after 3 months of age). ULOD is uncommon and recurrence is especially rare. We present the first recurrent case of ULOD GBS sepsis in 3-year-old girl with a past medical history of hydrops fetalis and thoracic congenital lymphatic dysplasia...

Congenital central hypoventilation syndrome (CCHS) is a form of sleep-disordered breathing characterized by a diminished drive to breathe during sleep, despite progressive hypercapnia and hypoxia. The condition results from mutations in the paired-like homeobox 2B (PHOX2B) gene. The aim of this review was to conduct a systematic search of the current data on CCHS as it relates to perioperative considerations and to discuss the classification, prevalence, pathophysiology, presentation, genetics, and management of the condition...

Retinopathy of prematurity (ROP) is a leading cause of potentially avoidable childhood blindness worldwide. With improvement in neonatal care, more preterm infants are surviving with a resultant increase in the number of ROP cases. In low-middle income countries, the disease epidemiology is characterized by the occurrence of ROP at higher birthweight in premature babies with greater severity at presentation. In this article, we describe the ROP screening and management program at the All India Institute of Medical Sciences (AIIMS), New Delhi that has evolved over last three decades...

Retinopathy of prematurity (ROP), a well-known complication of preterm birth that can result in avoidable blindness and visual impairment, is especially sensitive to the quality of neonatal inpatient care and appropriate, well-monitored oxygen. In 2010, the annual incidence of blindness and visual impairment from ROP was estimated to be 32,200 cases worldwide. The greatest burden is seen in middle-income countries, particularly where coverage of neonatal inpatient care has expanded without due attention to the quality of care provided, and the neonatal nursing skills and training of those providing this care...

Pancreatic β cells are functionally programmed to release insulin in response to changes in plasma glucose concentration. Insulin secretion is precisely regulated so that, under normal physiological conditions, fasting plasma glucose concentrations are kept within a narrow range of 3·5-5·5 mmol/L. In hyperinsulinaemic hypoglycaemia, insulin secretion becomes dysregulated (ie, uncoupled from glucose metabolism) so that insulin secretion persists in the presence of low plasma glucose concentrations. Hyperinsulinaemic hypoglycaemia is the most common cause of severe and persistent hypoglycaemia in neonates and children...

BACKGROUND: Respiratory syncytial virus (RSV) is the major viral cause of infant and childhood lower respiratory tract disease worldwide. Defining the optimal target product profile (TPP) is complicated due to a wide range of possible vaccine properties, modalities and an incomplete understanding of the mechanism of natural immunity. We report consensus population level impact projections based on two mathematical models applied to a low income setting. METHOD: Two structurally distinct age-specific deterministic compartmental models reflecting uncertainty associated with the natural history of infection and the mechanism by which immunity is acquired and lost were constructed...

: Despite decades of research on necrotizing enterocolitis (NEC), the outlook for infants afflicted by this devastating disease is all too often bleak. The aim of this symposium at the BAPS conference in Amsterdam was to highlight recent advances in the knowledge of the epidemiology and diagnosis of NEC. There were important contributions on the disease in the United Kingdom, both from a neonatal and from a surgical point of view, whereas colleagues from the Netherlands and elsewhere in Europe shared their insights into novel diagnostic tools, both biofluid and imaging based...

Increased blood plasma concentration of the sulphur amino acid homocysteine (Hcy) is considered as an independent risk factor of the neurodegenerative diseases. However, the detailed molecular mechanisms by which Hcy leads to neurotoxicity have yet to be clarified. Recent research has suggested that neurotoxicity of Hcy may involve negative regulation of neural stem cell (NSC) proliferation. In the current study, primary NSCs were isolated from neonatal rat brain hippocampus and the inhibition in cell growth was observed after exposure to l50 μM and 500 μM L-Hcy...

BACKGROUND: Myocardial tolerance to ischemia is influenced by age and preoperative cyanosis through unknown mechanisms and significantly affects postoperative outcomes. Cytochrome c oxidase (CcOx), the terminal enzyme of the mitochondrial electron transport chain, may play a role in the susceptibility to ischemic-reperfusion (IR) injury. Our study aimed at investigating changes in human myocardial CcOx activity based on age and preoperative oxygen saturation to understand its role in transition from neonatal to mature myocardium and hypoxic conditions...

Usually, reads from transcriptome sequencing data unmapped to the target species reference genome are disregarded. A recent RNAseq project on the new fatal disease Bovine Neonatal Pancytopenia had indicated an unexplained immune response signature to a double stranded RNA virus. To unravel its background, contigs were de novo assembled from unmapped RNAseq reads and aligned against the bovine genome assemblies and multispecies NCBI databases. Lack of genuine virus sequence contigs rejected the hypothesis of a live virus being causal for the unexplained immune response...

It has been well-accepted that spinal cord glial responses contribute significantly to the development of neuropathic pain. Tremendous information regarding glial activities at the cellular and molecular levels has been obtained through in vitro cell culture systems. The in vitro systems utilized, mainly include primary glia derived from neonatal brain cortical tissue and immortalized cell lines. However, these systems may not reflect the characteristics of spinal cord glial cells in vivo. In order to further investigate the roles of spinal cord glial cells in the development of peripheral nerve injury-induced neuropathic pain using a culture system that better reflects the in vivo condition, our laboratory has developed a method to establish primary spinal cord mixed glial cultures from adult mice...

Streptococcus agalactiae (group B Streptococcus, GBS), is a Gram-positive, asymptomatic colonizer of the human gastrointestinal tract and vaginal tract of 10 - 30% of adults. In immune-compromised individuals, including neonates, pregnant women, and the elderly, GBS may switch to an invasive pathogen causing sepsis, arthritis, pneumonia, and meningitis. Because GBS is a leading bacterial pathogen of neonates, current prophylaxis is comprised of late gestation screening for GBS vaginal colonization and subsequent peripartum antibiotic treatment of GBS-positive mothers...
