Abstract
Background/Aim Oxidative stress is considered to have a significant role in the development of cardiovascular diseases (CVDs) as well as many other diseases. Therefore, the purpose of the study is to evaluate the antioxidant system status at pre- and post-operative period in newborns with congenital heart disease (CHD) requiring operation. Materials and Methods Fifty CHD patients participated in this research. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and thiobarbituric acid reactive substances (TBARS) levels were studied in blood samples. RACHS-1 score, blood lactate levels, and hypoxic events were also recorded. Comparisons of antioxidant system parameters were conducted at pre- and post-operative periods and also between exitus and discharged groups. Results GPx activity and TBARS levels were significantly higher in the pre-operative period than post-operative period though the other antioxidant enzymes were not altered. In pre-operative period, GPx activity was low in addition to rarer hypoxic events in the discharged group. Also, a negative correlation was found between SOD and GPx activities in pre-operative period. Conclusion The results provide fundamental data showing the lowered GPx activity and TBARS levels considered as sensitive oxidative biomarkers after the operation. It was assumed that antioxidant system parameters might show changes after the operation, and GPx is prominent for resistance to hypoxic conditions. Post-operative reduction of GPx and TBARS levels is significant for evaluating the antioxidant system alterations after the operation. However, further investigations follow long-term duration for post-operative monitoring to estimate how antioxidant system status changes to improve the treatment of the health condition.

Abstract
Aim To evaluate the effect of umblical cord clamping time on lymphocyte subgroups in term and late preterm infants. Material and Methods Seventy-four infants between 34 and 41 weeks of gestation were included in the study. Of these, 37 were umbilical cord clamped immediately after birth and the remaining 37 were clamped after waiting one minute. Babies were divided into two groups as term and preterm. The prenatal, natal, postnatal characteristics of the infants were recorded. Hematologic and lymphocyte subgroups were investigated in cord blood and venous blood at day 7. Lymphocyte subgroups were evaluated using flow cytometry. Results With the delay of cord clamping, the leucocytes count and the percentage of CD3+T lymphocytes in cord blood of preterm infants decreased and this decrease continued at day 7. On the contrary, CD19+B lymphocyte levels in the cord blood of preterm infants increased, and this increase continued at day 7. Also, the percentage of CD4+T lymphocytes of preterm infants decreased with the delay of cord clamping at day 7. There was no difference between groups for the rate of sepsis development. Conclusion With the delay of cord clamping, the leucocytes count, the percentage of CD3+T, and CD4+T lymphocytes decreased, and the percentage of CD19+B lymphocytes increased in preterm infants. The delay in cord clamping time in term and preterm infants seems to have no impact on the rate of sepsis development. Larger series of studies are needed to assess the effect of these findings on the development of infection in late preterm infants who have delayed cord clamping.

Abstract

Neonatal uterine prolapse is rare and mostly due to spina bifida. It is probably due to abnormal innervation of levator ani and subsequent atrophy of the muscle in patients with spina bifida. Here we report a newborn patient with uterine prolapse after meningomyelocele operation. Foley catheter was used to manage uterine prolapse, however rectal prolapse occurred and catheter was pulled out. She was followed in an outpatient clinic without any management. She is now seven months old and had no uterine prolapse since the age of two months.

Abstract
Fluid and electrolyte balance and acid-base homeostasis are essential components of normal cellular and organ functions, both in the intrauterine and postnatal developmental period. Knowledge of physiologic changes and appropriate management are important aspects of neonatal intensive care. The aim is to ensure successful transition from the fetal to neonatal period and maintain a normal fluid-electrolyte and acid-base balance. In this paper, fluid and electrolyte requirements in the neonate, treatment of sodium and acid-base disorders on which some controversy exists, and also perioperative fluid-electrolyte management are reviewed.

Abstract
Background/aim:
Peritoneal dialysis (PD) is generally considered the practical dialysis modality for neonates in the treatment of acute
kidney injury (AKI) and metabolic disturbances. The aim of this study was to evaluate the indications, complications, and outcomes of
PD between January 2011 and December 2016.
Materials and methods:
This study included all 56 neonates that underwent PD over six years in our neonatal intensive care unit
(NICU). A retrospective chart review was performed for all patients in our institution.
Results:
The incidence of PD was 1.32% (56/4230 patients) during this period. Mean birth weight of the patients was 2267.77 ± 1060.63
(540–5050) g. Thirty-four (60.7%) patients were premature. Fourteen patients (25%) were in the postoperative period of cardiac surgery
due to congenital cardiac defects, fourteen patients (25%) were diagnosed with metabolic diseases, one patient had hypoxic ischemic
encephalopathy, and another patient had severe pulmonary hypertension.
Conclusion:
In the acute setting of a neonatal intensive care unit, PD performed in a neonate provides a technically simple method of
steady fluid, solute removal, and correction of electrolyte abnormalities. A trocar catheter appears safe even in premature babies, and
closed three-way stopcock system seems to be reliable at the bedside in NICUs.

Abstract
BACKGROUND The aim of this study was to determine mortality risk by calculating Score for Neonatal Acute Physiology and Perinatal Extension II (SNAP-PE-II) and Clinical Risk Index for Babies (CRIB) score, and evaluate prediction of the effects of antenatal corticosteroid and surfactant treatment on mortality. METHODS This multicenter study was conducted simultaneously in five different centers in four different provinces in Southern Turkey between July 2012 and July 2013. A total of 1668 inborn subjects hospitalized in the neonatal intensive care unit within the first 12 h of delivery, and meeting the selection criteria, were included in the study, and CRIB and SNAP-PE-II were used to determine mortality. RESULTS The SNAP-PE-II scoring system was applied to all patients, and the CRIB scoring system was used for 310 newborns with gestational age <32 weeks and weighing <1500 g. Of the 1668 patients, 188 died (mortality rate, 11.3%). Cut-off was found to vary with center, which changed specificity and sensitivity of the mortality scores. SNAP-PE-II significantly predicted mortality (P < 0.05) compared with CRIB. SNAP-PE-II also successfully predicted mortality in the group receiving antenatal corticosteroid compared with the group not receiving antenatal corticosteroid. CONCLUSION SNAP-PE-II was a significant predictor of mortality in newborns with birthweight <1500 g compared with CRIB, and assessment of antenatal corticosteroid use in conjunction with SNAP-PE-II increased the accuracy of the prediction of mortality.
