Purpose: The purpose of this study was to investigate pediatric nurse parent partnership and factors associated with this partnership. Methods: A survey was conducted with 158 nurses working in pediatric practice at one of 7 hospitals in Seoul, Incheon, and Chungcheongbuk Province. Data were collected from September to December 2013, and analyzed with SPSS Windows 21.0. Results: In hierarchial multiple regression analysis, self-efficacy (${\beta}$=.19, p=.016), clinical decision making (${\beta}$=.15, p=.046), and empowerment (${\beta}$=.29, p=.001) were associated with pediatric nurse parent partnership, after adjusting for marital status, children, education, position and satisfaction with work unit. These factors accounted for 44.0% of the variance in the pediatric nurse parent relationship. Conclusion: These results suggest that pediatric nurse parent partnership could be influenced by the predictors. Ultimately, intervention programs focusing on these factors should be effective in helping pediatric nurses improve partnership with parents.

The purposes of this study are to assess iron status in mothers and their newborn infants at birth and to analyze the influence of maternal iron status on their newborn babies. Venous bloods samples were drawn from 144 pregnant women just before delivery and cord bloods of their newborn babies were collected immediately after birth for measurement of hemoglobin, hematocrit, serum iron, ferritin, total binding capacity and transferrin saturation. The values of hemoglobin and hematocrit were significantly lower in the mothers(10.9$\pm$1.43g/dl and 33.7$\pm$3.67%) than in their newborn infants(14.7$\pm$1.43g/dl and 45.3$\pm$4.76%)(p<0.0001). At delivery, serum iron levels in cord blood were about twice as high as those in the maternal blood, and serum ferritin levels in the cord blood were about four times higher than those in the maternal blood. The serum ferritin levels of multigravidas were higher than those of primigravidas,. but there was no difference between the serum ferritin levels of their infants. The serum ferritin levels of the mothers and their infants were higher in maternal group with iron supplement regularly than in other maternal group without iron supplement during pregnancy. Among the mothers, 26.4% had a serum ferritin levels below 12ng/ml(i.e. depleted iron stores)and 78.9% had a hemoglobin below 12g/dl(i.e.iron deficient anemia). When the maternal group was classified according to their serum ferritin levels by 9ng/ml, 12ng/dl or 20ng/ml, there was no significant difference in the iron status of their newborn infants among the three groups. The hemoglobin and serum ferritin levels of the mothers were well correlated with those of their babies. The maternal hemoglobin values negatively correlated with infant birth weight. It is possible that the demands of iron of the mother might be increased in the case of a newborn infant of greater size. The results of this study provide useful information regarding establishment of RDA for iron in pregnant women and guidance about the need for iron supplement during pregnancy.

Congenital central hypoventilation syndrome (CCHS) or Ondine's curse is a very rare sleep disorder that is the result of a congenital failure of the autonomic control of ventilation caused by insensitivity of the chemoreceptor to hypercapnea during sleep. Gastrointestinal motility disorders, particularly a congenital megacolon (Hirschsprung disease) is often combined with CCHS. This combination can be explained by a defect in the migration of neuronal cells from the neural crest (neurocristopathy) during the intrauterine period. A diagnosis of CCHS is made by confirming the failure of adequate ventilation in response to hypercapnea and hypoxia during sleep and the exclusion of other diseases. Young infants frequently show atypical clinical courses, and their conditions are frequently complicated with the long-term sequela of hypoxemic episodes. Therefore, a high index of suspicion and active treatment with mechanical ventilation are important for reducing recurrent hypoxemic episodes in the neonatal period. This paper reports the follow up of a case of CCHS in a neonate who showed frequent intractable apnea and cyanosis and was given artificial mechanical ventilation during sleep.

Imperforated hymen, vaginal atresia or high transverse vaginal septum are caused by incomplete vaginal canalization. The infant may be present with distention of the vagina and the uterus with glandular secretions stimulated by maternal estrogens, known as hydrometrocolpos. We report two cases of hydrometrocolpos. In the first case, distal vaginal atresia with cystovaginal fistula was revealed by a contrast fluoroscope through the percutaneous catheterization. In the second case, urogenital sinus was detected by a fistulogram through a single orifice in the genital area. We decompressed the cystic mass by ultrasonogram guided aspiration, promptly at birth, then achieved the transient drainage of cystic fluids by percutaneous catheterization.

This review describes the neurophathological mechanisms that are implicated in perinatal brain injury. Perinatal brain injury is the most important cause of morbidity and mortality to infants, often leading to spastic motor deficits, mental retardation, seizures, and learning impairments. The immature brain injury is usually caused by cerebral hypoxia-ischemia, hemorrhage, or infection. The important form of perinatal brain injury is the hypoxic-ischemic injury and the cerebral hemorrhage. The pathology of hypoxic-ischemic injury include delayed energy failure by mitochondrial dysfunction, neuronal excitotoxicity and vulnerability of white matter in developing brain. The immature brain has the fragile vascular bed of germinal matrix and can not effectively centralize their circulation. Therefore, the cerebral hemorrhage process is considered to be involved in the periventricular leukomalacia.

New-born babies who require special attention medically are admitted often to incubator. Incubators are well equipped to fulfill take care of infants, but they have to hospital and so expensive. This paper proposes a smart incubator that can solve the problem of convenience and cost aspect of these incubators. Developed incubator enables near-field monitoring using Arduino Uno as the main control device and Bluetooth communication. The environment in the incubator measures temperature and humidity using a DHT22 sensor and the sound using a P5510 microphone. If the temperature and humidity data set by the user are lower or higher than the reference value, it is designed to operate the heating pad using the controller or turn on the fan to allow air circulation. The measured values in the incubator are displayed in real time on the user's smartphone monitoring screen and are programmed using app inventor. Developed incubators can help take care of infants at low cost in the home.

Hyperbilirubinemia is the most common neonatal disease and is observed in about 80% of newborns worldwide in neonatal period within a week after birth. Untreated infant hyperbilirubinemia may lead to brain damage and even death, so it is very important to diagnose it quickly and accurately. In this study, a total bilirubin measurement system was developed that is portable and easy to use without pre-processing using a commercial smartphone. This system measures using the LED and camera of the smartphone without the need for additional devices, and because a small amount of blood is injected without pre-treatment, anyone can easily measure it in the field. In a comparative study with Cobas c111 results, accuracy meets CLIA guidelines with 94% (17/18) within ±0.4 mg/dL below 3 mg/dL and 98% within ±20% above 3 mg/dL (276/282). This system offers a simple, fast and accurate diagnosis for jaundice in infants and young children in low-resource settings.

Purpose : Forward pulmonary blood flow may be absent in some neonates with Ebstein's anomaly by anatomical or functional pulmonary atresia in association with the elevated pulmonary vascular resistance, patent ductus arteriosus and tricuspid regurgitation. We reviewed the presentation and outcomes of symptomatic neonates with Ebstein's anomaly focusing on the pulmonary atresia. Methods : Clinical presentation and outcome of 15 symptomatic neonates with Ebstein's anomaly seen at Asan medical center from 1998 to 2004 were reviewed. Results : Ten(67%) of 15 patients showed no forward pulmonary blood flow and 6 of them had functional pulmonary atresia. $O_2$ saturation and pH were lower and cardiothoracic(CT) ratio in chest radiography was more increased in the patients with pulmonary atresia than in the patients without pulmonary atresia(P<0.05). pH and CT ratio were not different between the anatomical and functional pulmonary atresia group, but $O_2$ saturation was lower in functional atresia group(P<0.05). 13 patients(87%) were managed with $PGE_1$. 4 of 6 patients with functional pulmonary atresia were treated with inhaled nitric oxide. Surgery was performed in 1 of 5 patients without pulmonary atresia and in 8 of 10 patients with pulmonary atresia during follow-up period(mean 37 months). 3 patients(20%) died and none of patients without pulmonary atresia died. Conclusion : We found that most symptomatic neonates with Ebstein's anomaly had functional or anatomical pulmonary atresia. The neonates with Ebstein's anomaly who had no forward pulmonary blood flow were more symptomatic and needed surgery earlier. Further studies will be needed to distinguish effectively functional and anatomical pulmonary atresia and to manage appropriately neonates with functional atresia.

Purpose : A prospective, controlled trial was conducted to evaluate growth, efficacy, safety and nutritional status for very low birth weight infants fed with human milk fortified with Maeil human milk fortifier (Maeil $HMF^{(R)}$; Maeil Dairies Co., Ltd.). Methods : We enrolled 45 premature infants with a birth weight <1,500 g and gestational age <33 weeks, who were born at Dong-A University Hospital from October, 2006 through December, 2007. They were divided into 2 groups: infants in one group were fed with human milk fortified with $HMF^{(R)}$, and the second were fed with preterm formula. Growth, biochemical indices, feeding tolerance, and other adverse events in each group were assessed serially and compared relatively. Follow-up data were also collected after discharge at 1, 3, and 6 months corrected age. Results : Characteristics of the 2 groups including average gestational age, birth weight, sex, respiratory distress syndrome, patent ductus arteriosus, and other adverse events (sepsis, retinopathy of prematurity, and intraventricular hemorrhage) showed no significant difference. Average feeding start day ($8.00{\pm}3.27d$ vs. $8.86{\pm}5.37d$) (P=0.99) and the number of days required to reach full feeding after start feeding ($41.78{\pm}20.47d$ vs $36.86{\pm}20.63d$) (P=0.55) were not significantly different in the group fed human milk fortified with $HMF^{(R)}$ when compared with the group that was fed preterm formula. The duration of total parenteral nutrition and the incidence of feeding intolerance also showed no differences between the 2 groups. Although infants fed with human milk fortified with $HMF^{(R)}$ showed faster weight gain than those fed with preterm formula at the end stage of the admission period, other growth indices of the two groups showed no significant difference. No significant correlations were found between the 2 groups with regard to weight gain velocity, height gain velocity, head circumference velocity, and post-discharge follow up growth indices. Conclusion : Premature infants fed human milk fortified with $HMF^{(R)}$ showed no significant difference compared with those fed preterm formula in growth, biochemical indices, and adverse events. Using human milk fortifier can be an alternative choice for very low birth weight infants, who need high levels nutritional support even after discharge from NICU.

To investigate nutritional and growth status of premature infants, survey was conducted against 19 premature infants admitted to Nursery of Pediatrics, Young nam University Hospital from Jan. 1984 to July 1988. Variations in feeding patterns as analyzed through the five feeding phases of dextrose, dextrose/hyperal, dextrose/formula, dextrose/hyperal/formula and formula. During 30days from birth, dietary intake, feeding phase, selective anthropometric measurements, biochemical parameters and demograpic information of premature infants were as follows: Distributions of birth weight by gestational age and apgar score showed preamture infants below 1499g were 31 weeks, 4/7(1min/5min) and premature infants from 1500g to 1999g were 33 weeks, 8/9(1min/5min) and premature infants from 2000g to 2500g were 33 weeks, 8/9(1min/5min). Average calorie intakes of premature infants below 1499g, premature infants from 1500g to 1999g and premature infants from 2000g to 2500g were 102.0㎉/kg/day, 119.3㎉/kg/day and 101.7㎉/kg/day. The mean values Na, K, Ca, P for all premature infants remained within the normal level for full term infants throughtout the 25days of this study period. Percentages of inital weight loss showned premature infants below 1499g were 5.4%, premature infants from 1500g to 1999g were 6.4%, premature infants from 2000g to 2500g were 11.4%. Percentages of inital weight loss of the amino acid injection group and the amino acid control group were 9.4% and 9.0%.
