Using an eyelid conditioning paradigm modeled after that developed by Little, Lipsitt, and Rovee-Collier (1984), Fifer et al. (2010) demonstrated that newborn infants learn during sleep. This study examined the role of sleep state in neonatal learning. We recorded electroencephalogram (EEG), respiratory, and cardiovascular activity from sleeping full term newborn infants during delay eyelid conditioning. In the experimental group (n = 21), a tone was paired with an air puff to the eye. Consistent with Fifer et al...

Diagnosis of mitochondrial respiratory chain disorder (MRCD) is often difficult. Its pathogenesis is still unclear. We diagnosed MRCD by measuring the activity of the mitochondrial respiratory chain enzyme, and the patient also had hemophagocytic lymphohistiocytosis (HLH). A preterm female infant was born at 34 weeks of gestation. On day 6, HLH was revealed by bone marrow aspiration. She died on day 10 due to uncontrollable HLH. An autopsy was performed, and we measured the activity of the mitochondrial respiratory chain enzyme in the liver, muscle, and heart...

Studies suggested the presence of foetal adrenal rhythms of cortisol, which are entrained in antiphase to maternal rhythms. In contrast, neonates are thought to have no adrenal rhythm until 2-3 months after birth. To test the hypothesis that a foetal-type adrenal rhythm is preserved after birth, saliva samples were collected from 65 preterm/term infants during hospital stay (30-40 weeks corrected age) at 10:00 and 19:00 h. Cortisol levels were assessed for their diurnal difference and dependence on antenatal/postnatal clinical variables...

Neonatal respiratory distress is an emergent condition with a wide differential diagnosis. A 12-day-old newborn presented to the emergency department in respiratory distress. Point-of-care ultrasound allowed clinicians to rapidly exclude cardiac disease and pneumothorax as possible causes of the patient's respiratory distress, and expedited the identification of congenital diaphragmatic hernia. The ultrasound findings and technique, epidemiology, pathophysiology, and radiological diagnosis of congenital diaphragmatic hernia are reviewed...

BACKGROUND: Intrahepatic cholestasis of pregnancy (ICP) is a specific pregnancy-related disorder without standard medical therapies. Ursodeoxycholic acid (UDCA) is the most used medicine, but the efficacy and safety of UDCA remain uncertain. Several meta-analyses had been made to assess the effects of UDCA in ICP. However, the samples were not large enough to convince obstetricians to use UDCA. We conducted a meta-analysis to evaluate the effects and safety of UDCA in patients with ICP, which included only randomized controlled trials (RCTs)...

A 12-day-old boy presented with duskiness 4 h after circumcision with local anesthesia: infiltration with lidocaine (6 mL 1 %) and topical EMLA cream (2.5 % lidocaine/2.5 % prilocaine). He had no respiratory distress, but a strikingly dark skin. A blood sample showed dark, chocolate brown blood with a raised methemoglobin of 49.8 % (normal <1.5 %) and a lactate of 10 mmol/L. A diagnosis of methemoglobinemia was made. The patient was treated with oxygen administration, but methemoglobin concentration was still 45 % 1 h later...

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 Jarcho-Levin syndrome, also known as spondylothoracic dysplasia and spondylocostal dysplasia, is characterized by varieties of vertebrae and rib anomalies. Jarcho-Levin syndrome is a clinical-radiological diagnosis with clinical evidence of short neck, short trunk, normal-sized limbs, or increased arm span, and vertebral and rib defects on the skeletal survey. CASE REPORT About 400 cases have been reported in world literature and 18 in our Indian literature. We report the case of a one-day-old female baby with a short trunk, short neck, low hairline, apparently long limbs, protuberant abdomen, mild midfacial dysmorphism, low-set ears, and a high-arched palate...

PURPOSE: Spontaneous colon perforations are usually encountered as necrotizing enterocolitis in the neonatal period, but occur rarely in infants and children without pathological conditions. This study was conducted to describe its clinical implication beyond the neonatal period. METHODS: Cases of spontaneous colon perforation confirmed after the operation were reviewed retrospectively and the clinicopathological characteristics were analyzed. Clinical data were compared according to the presence of pneumoperitoneum as initial findings...

The aim of this study was to determine the clinical outcome of late preterm infants (LPI) week by week. Our patients were divided into three groups according to gestational age (GA); group A: 34 - 34+6/7 weeks, group B: 35 - 35+6/7 weeks and group C: 36 - 36+6/7 weeks. Out of 10650 deliveries, 1280 (12%) were late preterm, 1004 (78.5%) of which were carried out by caesarean section. A total of 1527 infants were studied with 565 (37%) requiring admission to NICU while 5 deaths were recorded (neonatal mortality rate was estimated at 3...

Early-term infants incur higher risks for neonatal morbidities compared to full-term infants. In this study, we investigated the neonatal morbidities in early-term infants admitted to a neonatal intensive care unit (NICU). Early-term (37 0/7 and 38 6/7 weeks of gestation) and full-term (39 0/7 and 41 6/7 weeks of gestation) infants born between January 2013 and December 2014 were enrolled in this study. Early-term deliveries accounted for 8,026 (25.7%) of all live births (n = 31,170). The admission rate of early-term infants to the NICU was 7...

The surfactant complex, thanks to its multiple actions including decrease of surface- tension and antimicrobial activity, plays a fundamental role in newborn survival, lowering the risk of respiratory distress syndrome. The aim of this work was to determine if the synthesis of two surfactant proteins (SP), SPA and pro-SPB, shows some inter-individual variability during lung development in the intrauterine life. Immunoreactivity for SPA and pro-SPB was investigated in the lungs of  40 subjects, including 15 fetuses, ranging from 14 to 22 weeks of gestation, and 25 neonates, from 24 to 41 weeks...

BACKGROUND: Established in 2000, Millennium Development Goal 4 (MDG4) catalysed extraordinary political, financial, and social commitments to reduce under-5 mortality by two-thirds between 1990 and 2015. At the country level, the pace of progress in improving child survival has varied markedly, highlighting a crucial need to further examine potential drivers of accelerated or slowed decreases in child mortality. The Global Burden of Disease 2015 Study (GBD 2015) provides an analytical framework to comprehensively assess these trends for under-5 mortality, age-specific and cause-specific mortality among children under 5 years, and stillbirths by geography over time...

BACKGROUND: Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specific mortality for 249 causes in 195 countries and territories from 1980 to 2015. These results informed an in-depth investigation of observed and expected mortality patterns based on sociodemographic measures. METHODS: We estimated all-cause mortality by age, sex, geography, and year using an improved analytical approach originally developed for GBD 2013 and GBD 2010...

Perinatal exposure to adverse experiences disrupts brain development, including the brainstem network that regulates breathing. At adulthood, rats previously subjected to stress (in the form of neonatal maternal separation; NMS) display features reported in patients suffering from sleep disordered breathing, including an increased hypoxic ventilatory response and hypertension. This effect is also sex-specific (males only). Based on these observations, we hypothesized that NMS augments the carotid body's O2-chemosensitivity...
