Abstract
INTRODUCTION Retinopathy of prematurity (ROP) is one of the main reasons of preventable childhood blindness. In the development of ROP, MicroRNAs may be effective in the balance of factors that inhibit and activate angiogenic factors. We aimed to determine the changes in the blood levels of miR-146a, miR-143, miR-210, miR-21, miR-126, miR-211, miR-221, miR-106 and let 7f and to investigate their association with ROP. We hypothesed that the level of these miRNAs changed significantly in ROP cases. MATERIALS AND METHODS This observational study was conducted prospectively in preterm infants with ROP. Serum levels of 8 miRNAs were measured. The relationship between disease stage and progression with miRNA gene expression was analysed. Preterm infants without ROP were taken as the control group. RESULTS 47 patients with ROP and 14 controls, were included in the study. In the ROP group, miR-210, miR-146a, miR-21 were statistically significantly lower. In the ROP group the expression level of miR-143 was insignificantly lower, miRNA-221 was insignificantly higher, and miR-106, miR-126 and let 7f were variable. CONCLUSION It was observed that miR-210, miR-146a, miR-21 and miR-143 were significantly lower in patients with ROP compared to the control group. However, no association could be established between the type of miRNA and stage of ROP. These miRNAs may be used as adjunctive biomarkers for diagnosis of ROP.

Abstract
BACKGROUND Hypoxic ischemic encephalopathy (HIE) is a significant cause of mortality and short- and long-term morbidities. Therapeutic hypothermia (TH) has been shown to be the standard care for HIE of infants ≥36 weeks gestational age (GA), as it has been demonstrated to reduce the rates of mortality, and adverse neurodevelopmental outcomes. This study aims to determine the incidence of HIE in our country, to assess the TH management in infants with HIE, and present short-term outcomes of these infants. METHODS The Turkish Hypoxic Ischemic Encephalopathy Online Registry database was established for this multicenter, prospective, observational, nationally-based cohort study to evaluate the data of infants born at ≥34 weeks GA who displayed evidence of neonatal encephalopathy (NE) between March, 2020 and April 2022. RESULTS The incidence of HIE among infants born at ≥36 weeks GA (n = 965) was 2.13 per 1000 live births (517:242440), and accounting for 1.55% (965:62062) of all neonatal intensive care unit admissions. The rates of mild, moderate and severe HİE were 25.5% (n = 246), 58.9% (n = 568), and 15.6% (n = 151), respectively. Infants with severe HIE had higher rates of abnormal magnetic resonance imaging (MRI) findings, and mortality (p<0.001). No significant difference in mortality and abnormal MRI results was found according to the time of TH initiation (<3 h, 3-6 h and >6 h) (p>0.05). TH was administered to 85 (34.5%) infants with mild HIE, and of those born of 34-35 weeks of GA, 67.4% (n = 31) received TH. A total of 58 (6%) deaths were reported with a higher mortality rate in infants born at 34-35 weeks of GA (OR 3.941, 95% Cl 1.446-10.7422, p = 0.007). CONCLUSION The incidence of HIE remained similar over time with a reduction in mortality rate. The timing of TH initiation, whether <3 or 3-6 h, did not result in lower occurrences of brain lesions on MRI or mortality. An increasing number of infants with mild HIE and late preterm infants with HIE are receiving TH; however, the indications for TH require further clarification. Longer follow-up studies are necessary for this vulnerable population.

Abstract
OBJECTIVE The aim of this study was to identify the effects of antenatal steroids (ANS) on acute kidney injury (AKI) in very low birth weight (VLBW) preterm infants. STUDY DESIGN We performed a retrospective cohort study of VLBW infants admitted to a tertiary-care neonatal intensive care unit between January 2016 and June 2019. Infants were divided into no ANS, partial ANS, and complete ANS groups. Serum creatinine (SCr) levels and rates of AKI during the first 2 weeks of life were compared. RESULTS During the study period, 335 infants met our inclusion criteria. Among no, partial, and complete ANS groups, there were significant differences in rates of stages 2 and 3 AKI (17, 11, and 6%, respectively). Logistic regression analysis revealed that complete ANS course was associated with lower rates of AKI (odds ratio [OR] = 0.41 95% confidence interval [CI]: 0.20-0.83) and stages 2 and 3 AKI (OR = 0.205 95% CI: 0.075-0.563) compared with no ANS. Infants in complete ANS group had significantly lower SCr at 72 hours of life and at discharge, SCr peak was compared with infants in no ANS group. CONCLUSION In VLBW infants, complete ANS exposure may be associated with improved renal function and decreased risk for AKI compared with no ANS. KEY POINTS · The effects of antenatal steroid treatment on renal function in preterm infants are not clear.. · A complete course of antenatal steroid decreases the risk for acute kidney injury in preterm infants.. · Infants who are not exposed to antenatal steroids need closer observation of their renal function..

Abstract
Multiorgan damage is a hallmark of hypoxic-ischemic encephalopathy and cardiovascular and hemodynamic changes during asphyxia contribute significantly to the brain damage. The main insult to the heart is myocardial damage and associated ventricular dysfunction, which is manifested by reduced preload and afterload. The immature myocardium reacts to asphyxia by bradycardia and reduced contractile capacity. Pulmonary hypertension aggrevates cardiac dysfunction. Hypothermia is the only effective treatment for HIE but it may also affect the heart and peripheral vascular system leading to bradycardia and peripheral vasoconstriction. In fact, these effects might be cardioprotective also. Rewarming after hypothermia may increase the heart rate and cardiac metabolism, augmenting the cardiac output. Monitoring of patient with HIE during and after hypothermia is possible by using near-infrared spectroscopy, echocardiography and electrocardiography. Cerebral effects may be monitored by magnetic resonance imaging also. Management should include the physiological status of the patient and appropriate treatments, including inotropes, vasopressors or rarely fluid boluses. Dopamine should not be used unless absolutely necessary. Drugs like melatonin and magnesium are under investigation. All treatments should be evidence-based and targeted echocardiography should be used more often in these vulnerable infants.

Abstract
Objective: Children with thalassemia major (TM) are prone to growth failure and micronutrient deficiency. Thus, this study aimed to evaluate nutritional status, anthropometrics, and bone mineralization defects in patients with regular blood transfusion. Methods: Data obtained were analyzed by evaluating laboratory tests, anthropometric measures, and bone mineral density. Results: This study included 29 patients (62% male and 38% female) with a mean age of 12.26±4.74 years, mean pre-transfusion hemoglobin of 8.64±1.01 g/dL, and mean serum ferritin of 1158.6±556.8 ng/mL. Vitamin D (72.4%), selenium (72.4%), and folate (37.9%) deficiencies were most frequent. Hypocalcemia was observed in 17.2%, hypomagnesemia in 3.5%, and decreased ceruloplasmin in 10.3% of patients. Folate was higher between 2 and 6 years old (p=0.028). Ceruloplasmin was higher between 6 and 10 years old (p=0.018). Selenium was significantly higher in patients with a ferritin of ≥1,500 (p=0.008). No significant ferritin-related differences were found in other micronutrients (p>0.05). Body mass index (BMI) were <5 percentile (p) in 31% of patient, whereas none was >95 p. Height in 24.5% and weight in 20.7% of patients were <3 p, whereas none with >97 p. BMI of patients aged 10-18 years was significantly higher (p=0.001). Anthropometric percentiles did not significantly differ in the mean serum ferritin and micronutrient levels. Hypoparathyroidism was observed in 13.8% and hypothyroidism in 3.5% of patients. Low bone density was detected in 14.8% (2 osteopenic and 2 osteoporotic) of patients. Bone mineral density did not significantly differ in the ferritin and micronutrient levels. Conclusions: Nutritional support and deficiency prevention are important to minimize the burden of complications and increase the life expectancy and quality in patients with TM.

Abstract
Objective To identify the incidence of and risk factors for acute kidney injury (AKI) in neonates with persistent pulmonary hypertension of the newborn (PPHN) and to evaluate its association with neonatal outcomes. Method A total of 78 newborns with confirmed PPHN admitted to the neonatal intensive care unit of a university hospital between 2016 and 2020 were retrospectively analyzed. AKI was defined according to the modified neonatal Kidney Disease: Improving Global Outcomes criteria. Results Of 78 PPHN infants, AKI was found in 29.5% (23/78). Multivariate analysis indicated that male sex (OR 3.43 95% CI 1.03-11.48, p=0.04) and severe PPHN (OR 5.67 95% CI 1.55-20.68, p<0.01) were independently associated with increased risk for AKI. Infants with AKI had significantly higher mortality rate than infants without AKI (43.5% vs. 9.1%, p<0.01). Mortality rates in stage 1, stage 2 and stage 3 AKI were similar (36.4%, 57.1%, and 40%, respectively, p=0.68). Among survivors, AKI infants had significantly longer mechanical ventilation and lenght of stay than infants without AKI. Conclusion In infants with PPHN, AKI is a common complication and is associated with increased mortality, and longer mechanical ventilation and lenght of stay. Careful monitoring of kidney function in infants with PPHN, especially in males and those who had severe PPHN can help to improve patient outcomes.

Abstract
BACKGROUND SARS-CoV-2 related multisystem inflammatory syndrome in children (MIS-C) is a newly defined clinical entity in pediatric ages resembles Kawasaki Disease or toxic shock syndrome. Here we aimed to raise awareness about this SARS-CoV-2 related syndrome. METHODS Children diagnosed with MIS-C and followed in Pediatric Clinic between November 2020 and January 2021, were included in study. Data about patients' demographic characteristics, clinical and laboratory findings, treatment and outcomes were collected from medical records. RESULTS The median age of 20 children with MIS-C was 80.5 months, 11 of them were male. The most common symptoms at admission were fever (100%), abdominal pain (70%), myalgia (50%), and rash (50%). Lymphopenia, elevated inflammatory markers and cardiac enzymes were their main laboratory findings. Cardiac involvement (90%) consisted of myopericarditis, valvulitis, left ventricular dysfunction, and coronary arteritis. Symptoms mimicking acute appendicitis and ileus were due to gastrointestinal involvement (50%). Macular rash on the trunk, erythema on upper eyelids were striking. Empiric antibiotics and intravenous immunoglobulin were used in all patients, glucocorticoids (90%), anti-thrombotic (65%) and vasoactive (45%) agents were used according to severity of disease. Response to IVIG treatment was poor, whereas glucocorticoids have dramatic affect. Seven patients (35%) were monitored in intensive care unit, none of them required intubation, mechanic ventilation or ECMO. The median recovery time, that is, the period when fever subside and inflammatory markers returned to normal was 9.5 days. CONCLUSIONS Glucocorticoids has critical role in treatment of MIS-C, early recognition and treatment may decrease need for intensive care by providing rapid recovery.

Abstract
COVID-19 disease affects all ages, but severe cases of the disease and mortality are very rarely seen among children. In most cases, they acquire the virus from their parents or from an another infected person. The exact reasons why the disease has a milder course in children is unknown but high numbers of Angiotensin Converting Enzyme-2 (ACE2) receptors, underdeveloped immune responses, cross-reaction with other viruses, protective effect of fetal hemoglobin and fewer outdoor activities as well as journeys, and nonexposure to air pollution, and smoking. Although many cases are asymptomatic, they can still shed the virus. Materno-fetal vertical transmission has not been shown so far. In symptomatic cases, clinical findings include fever and respiratory symptoms, followed by diarrhea and vomiting. There are signs indicating a possible association between Kawasaki disease and COVID-19. Clinical findings and diagnostic procedures in newborns, and older children are similar. Supportive therapy is essential and antiviral agents are not required in most cases. During cytokine storm, anti-inflammatory treatments may be tried. There is no evidence for transmission through breastmilk; therefore infected mothers should breastfeed their infants by taking all precautions. Routine immunizations of children should not be deferred during COVID-19 outbreak period. Psychological support for children who need to stay at home and for healthcare personnel should be provided.

Abstract
BACKGROUND Probiotics and prebiotics have strain-specific effects on the host. Synbiotics, a mixture of probiotics and prebiotics, are proposed to have more beneficial effects on the host than either agent has alone. PURPOSE We performed a randomized controlled trial to investigate the effect of Lactobacillus and Bifidobacterium together with oligosaccharides and lactoferrin on the development of necrotizing enterocolitis (NEC) or sepsis in very low birth weight neonates. METHODS Neonates with a gestational age ≤32 weeks and birth weight ≤1,500 g were enrolled. The study group received a combination of synbiotics and lactoferrin, whereas the control group received 1 mL of distilled water as placebo starting with the first feed until discharge. The outcome measures were the incidence of NEC stage ≥2 or late-onset cultureproven sepsis and NEC stage ≥2 or death. RESULTS Mean birth weight and gestational age of the study (n=104) and the control (n=104) groups were 1,197±235 g vs. 1,151±269 g and 29±1.9 vs. 28±2.2 weeks, respectively (P>0.05). Neither the incidence of NEC stage ≥2 or death, nor the incidence of NEC stage ≥2 or late-onset culture-proven sepsis differed between the study and control groups (5.8% vs. 5.9%, P=1; 26% vs. 21.2%, P=0.51). The only significant difference was the incidence of all stages of NEC (1.9% vs. 10.6%, P=0.019). CONCLUSION The combination of synbiotics and lactoferrin did not reduce NEC severity, sepsis, or mortality.

Abstract
BACKGROUND The aim of this study is to evaluate whether there is an association between the platelet mass and patent ductus arteriosus (PDA) closure in premature newborns. METHODS Preterm infants (gestational age ≤33 weeks) with hemodynamically significant PDA (group 1, n = 178) and a control group of preterm infants without PDA (group 2, n = 211) were retrospectively evaluated between August 1, 2013 and July 30, 2015 in the neonatal intensive care unit (NICU). Platelet counts and platelet indices including mean platelet volume (MPV), and platelet mass (platelet count x mean platelet volume) in the first 24 hours of life, demographic findings and morbidities were recorded. RESULTS No differences were observed in demographic findings between the study groups in terms of birth weight, gestational age, gender and maternal risk factors. The mean platelet count in the first postnatal hemogram in group 1 and group 2 were 189.43 ± 72.14 (X103 /mm3) and 206.86 ± 70.11(X103/mm3), respectively (P < 0.05). The MPV were similar in both groups (P > 0.05). Platelet mass values were 1443.70 ± 572.40 fL/nL in Group 1 and 1669.49 ± 1200.42 fL/nL in group 2. There was a statistically significant difference in platelet mass values between the two groups (P = 0.011). Multivariable analysis including presence of thrombocytopenia, MPV and platelet mass showed that hemodynamically significant PDA was not independently associated with platelet count <150 000 (OR = 1.001, 95% CI 0.980-1.023; P = 0.921), MPV (OR = 0.967, 95% CI 0.587-1.596; P = 0.897) or platelet mass (OR = 0.999, 95% CI 0.997-1.002; P = 0.681). The optimal cut-off value of platelet mass for patients with PDA was ≤1530.8 fL/nL (area under the curve [AUC]: 0.580), with sensitivity of 58% and specificity of 56.2% (P = 0.008). CONCLUSION Our data suggest that platelet count, MPV, and platelet mass do not contribute to closure of PDA in premature newborns.

Abstract
Objective: To investigate the incidence of perinatal features and neonatal morbidities in migrant mothers in comparison with native Turkish mothers. Method: A retrospective analysis was conducted using the medical records of 89 infants born to Syrian immigrants and 89 infants born to native Turkish mothers who were consecutively admitted to the neonatal intensive care unit of our hospital between 2015 and 2019. Statistical analyses were used to compare demographic data and perinatal and neonatal outcomes between the two groups. Results: Compared to Turkish mothers, Syrian mothers were significantly younger and adolescent pregnancy rate was significantly higher (p<0.01). The rates of multiple pregnancy, consanguineous marriage, and prolonged premature membrane rupture were also significantly higher in Syrian mothers (p<0.05). The incidence rates of congenital anomalies, respiratory distress syndrome, transient tachypnea of newborn pneumonia/bronchiolitis, sepsis, jaundice, and feeding problems were the same for infants born to Syrian and Turkish mothers (p>0.05). In addition, the two groups did not differ with respect to gestational week at birth, birth weight, sex, types of delivery, Apgar score, duration of hospital stay, and incidence of infant mortality (p>0.05). Conclusion: The immigrant status negatively affects perinatal and neonatal outcomes. However, the incidence rates of infant mortality and neonatal morbidity did not differ between infants born to Syrian and those born to Turkish mothers. This may be due to the recent improvements in the of overall health status of migrant women or of those migrants living in Turkey being able to have access to increased prenatal and postnatal period policies of mother-child health services which have been successfully implemented.

Abstract
PURPOSE To examine the prokinetic effect of clarithromycin in very low birth weight (VLBW) preterm infants. MATERIALS AND METHODS VLBW preterm infants who have not achieved half of the full enteral feeding in the second week of life were enrolled in the study. The infants enrolled in the study were randomized. Twenty infants received oral clarithromycin (7.5 mg/kg, twice a day) and 20 control infants did not receive any treatment. RESULTS Full enteral feeding was attained earlier in the clarithromycin group than in the control group [7 (6-9) versus 9 (9-11) days, respectively; p < .001]. Duration of parenteral nutrition and number of withheld feeds were significantly lower in the clarithromycin group (p = .013 and p < .001, respectively). Parenteral nutrition-associated cholestasis (n = 1 versus 3, p = .1) and length of hospital stay (50 versus 59 median days, p = .1) tend to be lower in the clarithromycin group without any statistical significance. We observed no adverse effect of clarithromycin therapy. CONCLUSIONS Clarithromycin treatment in VLBW preterm infants resulted in better toleration of enteral feeding. Larger randomized controlled trials are needed to establish routine use of clarithromycin in the treatment of feeding intolerance.

Abstract
BACKGROUND Vancomycin a frequently used antimicrobial for the treatment of late-onset neonatal sepsis. It can be infused either intermittently or continuously, however, there is no consensus on the optimal dosing regimen. AIM To evaluate microbiological outcomes, clinical response and adverse events of vancomycin when administered via continuos intravenous infusion. METHODS The files of preterm infants (<34 weeks), who received either intermittent (group I, n = 41) or continuous (group II, n = 36) vancomycin infusion for the treatment of late-onset sepsis, were investigated retrospectively. Clinical and demographic features were recorded. RESULTS Clinical improvement rates, Töllner scores and microbiological outcomes did not differ significantly between groups. At 48th hour of vancomycin infusion, 52.8% of infants achieved therapeutic concentrations of vancomycin in group II compared with 34.1% of patients in group I (p = 0.002). Thirty-nine percent of infants in group I had supratherapeutic concentrations of vancomycin at 48th hour compared with 5.6% in group II (p = 0.002). Dose adjustment rate in group I did not differ than group II (65.9% vs. 52.8% respectively, p = 0.3). However, when we subdivide group I into two according to dosing intervals, dose adjustment rates were more common in infants with a gestational age <29 weeks for whom intermittent infusion was performed in 18 hours intervals (92.9% vs 51.9% , p = 0.014). CONCLUSION In preterm infants, continuous and intermittent infusions of vancomycin have similar clinical efficacies. Continuous infusion is well-tolerated and require less blood sampling compared to intermittent infusion especially in infants less than 29 weeks of gestational age.

Abstract
PURPOSE To evaluate 2-year outcomes following intravitreal bevacizumab (IVB) as monotherapy for aggressive posterior retinopathy of prematurity (APROP). METHODS Medical records of 40 infants were retrospectively reviewed. Group I included infants who had received IVB injections for APROP. Group II included infants who underwent laser treatment for APROP. Anatomic and refractive outcomes and the presence of anisometropia and strabismus were assessed at follow-up examinations. RESULTS Group I included 48 eyes of 25 infants (11 males) with a mean gestational age (GA) of 26.40 ± 1.82 weeks and a mean birth weight (BW) of 901.40 ± 304.60 g. Group II included 30 eyes of 15 infants (6 males) with a mean GA of 27.30 ± 1.82 weeks and a mean BW of 941.00 ± 282.48 g. GA, BW, and gender distributions were similar between groups (P=0.187, P=0.685, and P=1.000, respectively). Refractive errors were significantly less myopic in group I (0.42 ± 3.42 D) than in group II (-6.66 ± 4.96 D) at 2 years (P=0.001). Significantly higher rates of anisometropia and strabismus were observed in group II than in group I (P=0.009 and P=0.036, respectively). CONCLUSIONS The study demonstrated that IVB monotherapy can be useful in the treatment of APROP. The decreased incidence of early unfavorable refractive and functional outcomes in the IVB group compared with the laser group showed a potential benefit for patients treated with IVB, and this needs to be better evaluated in future prospective studies.

Abstract
OBJECTIVE Preeclampsia leads to chronic intrauterine hypoxia by interfering with placental blood supply. The aim of this study was to investigate whether preeclampsia exposure has an influence on the central nervous system of infants, as monitored by amplitude integrated electroencephalography (aEEG). METHODS We recruited 52 infants with gestational age between 30 and 34 weeks. Twenty-seven infants were born to preeclamptic mothers, and 25 gestational age-matched infants whose mothers were healthy were enrolled as a control group. aEEG recordings were performed between 24 and 48 h of life using a cerebral function monitor (CFM) (Olympic Brainz monitor). Along with aEEG, middle cerebral artery (MCA) blood flow velocities (BFV) were measured using Doppler ultrasound. RESULTS The duration of quiet sleep was significantly shorter (P=0.001), and Burdjalov score was lower (P=0.04) in the preeclampsia group. However, there was no change in MCA BFV in this group. CONCLUSIONS Preeclampsia altered cerebral electrical activity of premature infants born to preeclamptic mothers.

Abstract
The aim of this study was to evaluate cerebellar growth of preterm infants. Vermis height and transverse cerebellar diameter were measured by cranial ultrasonography in 38 preterm infants (27-32 weeks) at birth and term equivalent age. Measurements were compared with 40 term appropriate-for-gestational-age infants. Preterms at term equivalent age had larger vermis height than term infants (2.39 ± 0.25 cm vs 2.25 ± 0.18 cm, P = .005), whereas no significant difference was found in the transverse cerebellar diameter (5.32 ± 0.38 cm vs 5.44 ± 0.23 cm, P = .13). Vermis height and transverse cerebellar diameter of appropriate-for-gestational-age preterm infants (n = 29) were found larger than small-for-gestational-age ones (n = 9). Vermis height and transverse cerebellar diameter at term equivalent age of appropriate-for-gestational-age preterm infants born before and after 29 weeks of age showed no significant difference. Cerebellar growth is preserved in extreme preterms. However, being small for gestational age may have deleterious effects on cerebellar development.

Abstract
OBJECTIVE Antenatal, postnatal follow-ups and laboratory findings of the cases with retained fetal lung fluid syndrome were evaluated to detect prognostic factors. STUDY DESIGN This study was conducted at Zeynep Kamil Maternity and Children's Training and Research Hospital including infants retained fetal lung fluid syndrome. Patients were divided into 3 groups according to duration of the clinical symptoms. Cases whose clinical findings resolving within first 24 hours constituted Group 1 (n = 31), cases with clinical findings persisting between 24 and 72 hours constituted Group 2 (n = 95) and cases with symptoms persisting >72 hours constituted Group 3 (n = 10). Antenatal and postnatal clinical data and laboratory findings of the patients were evaluated retrospectively. RESULT Pneumothorax, pulmonary hypertension, antibiotic use frequency and hospitalization periods were found to be prolonged in the patients admitted due to retained fetal lung fluid syndrome who were delivered with elective caesarean section, with low birth weight and gestational age, requiring intubation and invasive ventilation within first 12 hours, having low hemoglobin and blood chloride levels. CONCLUSIONS Low blood chloride level can be a laboratory finding predicting whether malignant tachypnea develops or not in retained fetal lung fluid syndrome. Cut-off chloride value for malignant tachypnea can be determined with new studies which will be performed in the future.

Abstract
OBJECTIVE This study aims to investigate the effects of antenatal magnesium sulfate on intestinal blood flow in preterm neonates. STUDY DESIGN In this prospective case-match study, 25 preterm neonates exposed to magnesium sulfate antenatally were included (study group). Overall, 25 gestational age-matched neonates who had no exposure to magnesium constituted the control group. Serial daily Doppler flow measurements of superior mesenteric artery (SMA) were performed. The time to reach full feeds, first meconium passage were assessed. Presence of feeding intolerance or necrotizing enterocolitis was recorded. RESULTS Blood flow velocities of SMA were not different between the groups during the first five postnatal days. However, SMA blood flow showed an increasing trend in the control group unlike the study group (control group, p < 0.001; study group, p = 0.29). There was no significant difference between the two groups regarding the time to reach full feeds or first meconium passage and presence of feeding intolerance. No case of necrotizing enterocolitis was seen. CONCLUSION Antenatal magnesium does not significantly affect intestinal blood flow, but it seems to attenuate the increasing trend of the intestinal blood flow in the early postnatal days. However, this study failed to show any impact of this finding on clinical outcomes.

Abstract
OBJECTIVE One of the most challenging aspects in the management of neonates with late-onset neonatal sepsis (LOS) is to make the diagnosis. Presepsin is a novel and promising marker of sepsis. The aim of this study was to assess the role of presepsin in the diagnosis of LOS in preterm infants. METHODS Forty-two premature newborns ≤32 weeks gestational age with a diagnosis of LOS were prospectively involved in the study. Forty gestational and postnatal age-matched infants without sepsis served as controls. Levels of presepsin, C-reactive protein, and procalcitonin were measured at enrollment and on the third and seventh days of sepsis. RESULTS Initial presepsin levels in the LOS group were significantly higher than in the control group (1024 pg/mL, min-max: 295-8202; versus 530 pg/mL, min-max: 190-782; p < 0.0001). The area under the receiver-operating curve for presepsin was 0.864. A presepsin value of 800.5 pg/mL was established as a cut-off value, with 67% sensitivity and 100% specificity. Presepsin levels gradually decreased during treatment. CONCLUSION Presepsin can be used as a reliable biomarker for LOS and treatment response in preterm infants. However, we could not demonstrate the efficacy of presepsin for the detection of disease severity or prognosis.

Abstract
OBJECTIVE This study aims to develop a scoring system for the prediction of bronchopulmonary dysplasia (BPD). METHODS Medical records of 652 infants whose gestational age and birth weight were below 32 weeks and 1,500 g, respectively, and who survived beyond 28th postnatal day were reviewed retrospectively. Logistic regression methods were used to determine the clinical and demographic risk factors within the first 72 hours of life associated with BPD, as well as the weights of these factors on developing BPD. Predictive accuracy of the scoring system was tested prospectively at the same unit. RESULTS Birth weight, gestational age, gender, presence of respiratory distress syndrome, patent ductus arteriosus, intraventricular hemorrhage, hypotension were the most important risk factors for BPD. Therefore, a scoring system (BPD-TM score) ranging from 0 to 13 and grouped in four tiers (0-3: low, 4-6: low intermediate, 7-9: high intermediate, and 10-13: high risk) was developed based on these factors. Below the score of 4, 4.1% of infants (18/436), above the score of 9, 100% (29/29) of the infants developed BPD. The score was validated successfully in 172 infants. CONCLUSION With this easy to use scoring system, one can predict the neonate at risk for BPD at 72 hours of life and direct preventive measures toward these infants.

Abstract
OBJECTIVE Since probiotics modulate intestinal functions and enterohepatic circulation; they might have an effect on neonatal hyperbilirubinemia treatment. The objective of this study was to investigate the efficacy of Saccharomyces boulardii supplementation on hyperbilirubinemia. STUDY DESIGN A prospective, double-blind, placebo controlled trial was performed on 35 to 42 gestational weeks' neonates. They were randomized either to receive feeding supplementation with S. boulardii 125 mg every 12 hours or placebo during phototherapy. Serum bilirubin levels were measured at 0, 24th, 48th, 72nd, and 96th hour of phototherapy. RESULTS A total of 119 infants (61 in the control group and 58 in the study group) were enrolled. The duration of phototherapy (2 [1-3] vs. 2 [1-3], p: 0.22) was not different between groups. The levels of bilirubin during phototherapy ([24th hour; 14.1 {12.8-15.7} vs. 13.5 {12.4-14.9}, p: 0.085]; [48th hour; 14.1 {12-15.3} vs. 13.4 {12.4-14.5}, p: 0.41]; [72nd hour; 13.9 {12.2-15.6} vs. 13.5 {12.5-14.5}, p: 0.41]; [96th hour; 14.7 {11.4-15.5} vs. 13.4 {10.7-14.1}, p: 0.24]) or the duration of rebound phototherapy (1 [1-1] vs. 1.5 [1-2], p: 0.40) were lower in the study group than in the controls, but none of the values were statistically significant. CONCLUSION S. boulardii did not influence the clinical course of hyperbilirubinemia significantly.

Abstract
OBJECTIVES To compare the efficacy of oral and intravenous paracetamol for closure of hemodynamically significant patent ductus arteriosus (HSPDA) in very low birth weight (VLBW) preterm infants. METHODS Eighteen VLBW infants with HSPDA treated with either intravenous (n = 10) or oral (n = 8) paracetamol at 60 mg/kg/d for three consecutive days were analysed retrospectively. Ductal closure rate and evaluation of liver function tests were the major outcomes. RESULTS After two courses of treatment, HSPDA closure rate was higher in oral paracetamol group than that in the intravenous paracetamol group (88% versus 70%), but it was not statistically significant (p = 0.588). Liver function tests were normal after the treatment. CONCLUSION Although it was not statistically significant, the cumulative closure rates were higher in oral paracetamol group than those in the intravenous group. Larger trials are needed to confirm these data.

Abstract
The purpose of the study is to evaluate the clinical outcome of laser photocoagulation (LPC) in the treatment of retinopathy of prematurity (ROP) at a referral hospital in Turkey. In this retrospective study, a chart review of infants who underwent LPC for ROP between June 2011 and June 2013 was done. Clinical and demographic characteristics, laser parameters, anatomic, and refractive outcomes were evaluated. Totally 113 infants (202 eyes) were enrolled in the study. Of the 202 eyes, 29 eyes had threshold ROP, 141 eyes had prethreshold ROP, and 32 eyes had aggressive posterior ROP (APROP) at initial interventions. The mean gestational age (GA) was 28.13 ± 1.99 weeks (range between 24 and 33 weeks), the mean birth weight (BW) was 1,147.77 ± 341.77 g (range between 530 and 2,000 g) and the mean postmenstrual age (PMA) at first laser treatment time was 35.79 ± 1.74 weeks (range between 33 and 39 weeks). The mean number of laser spots (NLS) applied for each eye was 1,358.05 ± 369.91. Eyes with APROP had higher number of NLS than eyes with threshold ROP and prethreshold ROP (P < 0.01). Anatomic outcome was favorable for 171 eyes (84.7 %) at the end of the 1-year follow-up. Refractive data were available for 56 infants (100 eyes). The mean refractive error was 0.00 ± 2.48D SE. The incidence of high myopia (>5D) and strabismus was 2 and 14.3 %, respectively. Laser photocoagulation is an effective therapy for ROP. Early and appropriate laser treatment improves the clinical outcome of the disease.

Abstract
PURPOSE To report the baseline plasma levels of vascular endothelial growth factor-A (VEGF-A), soluble vascular endothelial growth factor receptor-2 (sVEGFR-2) and soluble Tie2 in infants with treatment-requiring retinopathy of prematurity (ROP) and to investigate the effect of laser treatment on the plasma levels. METHODS Blood samples were collected from infants with prethreshold type 1 ROP before, 1 day after, and 1 week after confluent laser photocoagulation. Enzyme-linked immunosorbent assay procedure was used to determine plasma VEGF-A, sVEGFR-2, and sTie2 levels. RESULTS A total of 48 eyes of 30 infants were included. The mean postconceptional age at which laser photocoagulation was performed was 37.5 ± 2.9 weeks. The mean number of laser spots applied to each eye was 1,480 ± 420. Regression of active retinopathy occurred within 1 week of treatment in all cases. Baseline plasma VEGF-A, sVEGFR-2, and sTie2 levels did not differ between unilateral and bilateral and also zone I and zone II disease. A significantly progressive decrease was observed in plasma VEGF-A, sVEGFR-2, and sTie2 levels at 1 day and 1 week after laser photocoagulation. CONCLUSIONS Plasma levels of VEGF-A, sVEGFR-2, and sTie2 decreased significantly in our patients after laser treatment; however, because of the variability in the measurements, further studies evaluating the clinical value of these angiogenic factors in patients with treatment-requiring ROP are necessary.

Abstract
AIM To evaluate the rehospitalization rates of premature infants who received palivizumab prophylaxis and its influence on the growth and development of these infants. METHODS Infants with a gestational age of less than 32 weeks were randomized to receive prophylaxis with palivizumab (study group) or nothing (control group). Nasal swab samples were obtained monthly in all cases and also in case of infection and hospitalization. At the corrected age of 18 months Guide for Monitoring Child Development (GMCD) was administered to all patients and anthropometric indices were evaluated. RESULTS The study was completed with 39 infants in the study group and 40 infants in the control group. Incidence of hospitalization due to respiratory syncitial virus (RSV) was found to be significantly lower in the study group both at the year of prophylaxis and in the following year (p = 0.001, odds ratio 1.32 [1.11-1.57]). There were no significant differences in terms of anthropometric indices or GMCD tests between the groups at the corrected age of 18 months. CONCLUSION Palivizumab reduced the incidence of lower respiratory tract infections and hospitalizations due to RSV both in the year of prophylaxis and in the following year. However, this decrease did not have any impact on the development of infants.

Abstract
BACKGROUND As hyperbilirubinemia is a significant cause of brain injury, it is important to predict the cases who are at risk. Data for preterm infants are scarce. The aim of this study is to predict significant hyperbilirubinemia in preterm infants by measuring capillary bilirubin at 12th hour of life. METHODS One hundred and fifty neonates born ≤ 35 weeks were included in the study. They were categorized into two groups according to their birth weights (group 1: 1,000 - 1,499 g; group 2: 1,500 - 2,000 g). Their bilirubin levels were measured at 12th hour and daily thereafter for 5 days. Risk nomograms were generated based on their bilirubin measurements and postnatal ages. On the age-specific percentile-based nomogram, the zone above the 90th percentile was determined as high risk and those below the fifth percentile as low risk. Infants who had bilirubin levels over the limits defined according to their postnatal ages and birth weights were accepted to have significant hyperbilirubinemia and received phototherapy and predictive value of the 12th hour bilirubin was asssessed. RESULTS Fifty-four of 57 infants (94.7%) in group 1 and 75/93 infants (80.7%) in group 2 received phototherapy. Capillary bilirubin levels of 3.55 mg/dL and 4.55 mg/dL for group 1 and group 2 measured at the 12th hour of life had the highest sensitivity, negative and positive predictive value to predict the neonates who will develop significant hyperbilirubinemia. CONCLUSION Bilirubin levels of preterm infants should be monitored closely. More attention should be paid to the ones who had 12th hour bilirubin level above the cutoff values.

Abstract
BACKGROUND Evaluation of cerebellar morphology and measurement of its biometric parameters such as cerebellar vermis height and transverse cerebellar diameter may assist the neonatologist in monitoring cerebellar growth and development and detect abnormalities resulting from malformations, hemorrhage or ischemic infarction. AIM The aim of this study was to establish nomograms of cerebellar vermis height and transverse cerebellar diameter at birth in appropriate-for-gestational-age neonates by using cranial ultrasonography. STUDY DESIGN A cross-sectional observational study. Appropriate-for-gestational-age neonates were evaluated with cranial ultrasonography by the same neonatal sonographer. SUBJECTS Healthy appropriate-for-gestational-age neonates born between 26 and 42 weeks of gestation in their first postnatal 24 h. OUTCOME MEASURES Cranial sonographic measurements included cerebellar vermis height measured midsagitally from anterior fontanelle and transverse cerebellar diameter measured coronally from mastoid fontanelle. Measurements were taken for each gestational age between 26 and 42 weeks and nomograms were constructed. RESULTS Three hundred twenty-one consecutively born appropriate-for-gestational-age neonates (163 females and 158 males) were studied. A linear growth function was observed between vermis height and gestational age and between transverse cerebellar diameter and gestational age. CONCLUSION Nomograms of cerebellar vermis height and transverse cerebellar diameter against gestational age at birth in appropriate-for-gestational-age neonates have been constructed. This can help the neonatologist to assess variations from the normal during ongoing cerebellar growth and development and to diagnose cerebellar anomalies.

Abstract
BACKGROUND Probiotics have strain specific effects and the effects of fungi in preventing diseases in preterm infants have been investigated poorly. Saccharomyces boulardii is a yeast which acts both as a probiotic and a polyamine producer. AIM The objective of this study was to investigate the efficacy of S. boulardii in preventing necrotizing enterocolitis (NEC) or sepsis in very low birth weight infants. STUDY DESIGN AND SUBJECTS A prospective, double blind, placebo controlled trial was conducted in preterm infants (≤ 32 GWs, ≤ 1500 g birth weight). They were randomized either to receive feeding supplementation with S. boulardii 50 mg/kg every 12 h or placebo, starting with the first feed until discharged. OUTCOME MEASURES Necrotizing enterocolitis (NEC) or sepsis and NEC or death. RESULTS Birth weight and gestational age of the study (n = 104) and the control (n = 104) groups were 1126 ± 232 vs 1162 ± 216 g and 28.8 ± 2.2 vs 28.7 ± 2.1 weeks, respectively. Neither the incidence of stage ≥ 2 NEC or death nor stage ≥ 2 NEC or late onset culture proven sepsis was significantly lower in the study group when compared with the control group (9.6% vs 7.7%, p = 0.62; 28.8% vs 23%, p = 0.34). Time to reach 100 mL/kg/day of enteral feeding (11.9 ± 7 vs 12.6 ± 7 days, p = 0.37) was not different between the groups. CONCLUSIONS Saccharomyces boulardii did not decrease the incidence of NEC or sepsis.

Abstract
OBJECTIVE Fetal calprotectin levels increase in the early stages of necrotizing enterocolitis. Although the effects of several factors on fetal calprotectin have been studied, the effect of phototherapy is not known. In this study, we analyzed the effect of phototherapy on fetal calprotectin levels. METHODS Ninety breast-fed newborns (46 male, 44 female) who were hospitalized for indirect hyperbilirubinemia and treated with phototherapy were included to the study. Forty-two of them were term and 44 of them were preterm. Newborns treated with phototherapy (n = 53) constituted the phototherapy group (29 preterm, 24 term) and 37 newborns who did not receive phototherapy (19 preterm, 18 term) constituted the control group. Fecal samples were collected 24 hours after phototherapy had been started. Fecal samples (100 mg) were weighed with sensitive scales and preserved at -80°C after buffering with a special solution. All samples were studied at the same time with a fecal calprotectin kit by using enzyme-linked immunosorbent assay. RESULTS There were no statistically significant difference between fecal calprotectin levels of term and preterm babies who received phototherapy and babies who did not receive phototherapy. CONCLUSION There was no effect of 24-hour phototherapy on fecal calprotectin levels in preterm and term newborns.

Abstract
BACKGROUND Neonates are at high risk for nosocomial infections due to multidrug-resistant pathogens. The use of β-lactamase inhibitors in combination with β-lactam antibiotics broadens the antimicrobial spectrum. Cefoperazone/sulbactam is used in children but there are limited data on its usage in neonates. The purpose of the present study was therefore to evaluate the use of cefoperazone/sulbactam in the treatment of neonatal infections caused by multidrug-resistant pathogens. METHODS The records of neonates who were hospitalized and who received cefoperazone/sulbactam were reviewed. RESULTS There were 90 infants who received cefoperazone/sulbactam. A pathogen could be isolated in 41 (45.6%) of the infants. In total, 17.1% of isolated pathogens were resistant to cefoperazone/sulbactam. Side-effects were seen in four of the infants. Two infants had cholestasis, one infant had neutropenia and one had superinfection with candida. CONCLUSION Cefoperazone/sulbactam can be used in the treatment of nosocomial infections caused by multidrug-resistant pathogens in neonates.

Abstract
BACKGROUND Early diagnosis and appropriate management of neonatal hyperbilirubinemia are very important in order to prevent bilirubin encephalopathy and kernicterus. Several diagnostic tests may be used for this purpose, including bilirubin level itself. The aim of the present study was to investigate whether serum alkaline phosphatase (ALP), which is an intracellular enzyme found abundantly in red blood cells, could be used for the early diagnosis and prediction of hyperbilirubinemia in newborns. METHODS A total of 100 babies were evaluated, starting from the sixth hour after birth, and serum ALP and bilirubin levels were analyzed. RESULTS ALP levels were significantly higher in babies requiring therapy such as phototherapy or exchange transfusion (247.01 ± 67.44 IU/L vs 154.25 ± 56.07 IU/L). ALP levels rose significantly with rising total bilirubin level. CONCLUSION ALP levels at the sixth hour of life may be a significant predictor of developing hemolysis and hyperbilirubinemia requiring treatment.

Abstract
OBJECTIVE Many different factors are involved in the pathogenesis of preterm deliveries and among them maternal or perinatal infections and inflammatory response have the major role. Researches were carried out about resistin, which is thought to have a role in inflammatory cytokine cycle and it was shown to be associated with growth in neonates. However, no research has been carried out showing its relationship with inflammation in neonates. In this study, we aimed to evaluate the resistin levels in premature neonates and the effect of events such as preterm prelabour rupture of the membranes (PPROMs) and the use of antenatal steroids on these levels. STUDY DESIGN The study included 118 preterm neonates. Their medical data together with their mothers' were recorded. Serum resistin levels together with interleukin (IL)-6, C-reactive protein (CRP) and procalcitonin were evaluated in the first 2 h of life. RESULT Mean gestational age and birth weight of babies included in the study were 29.6 ± 2.7 weeks and 1306.4 ± 393.4 g, respectively. Babies with PPROMs had significantly higher levels of resistin ((n=30); 70.7 (7.8 to 568.4) ng ml(-1)) than babies without PPROM ((n=88); 25.9 (5.5 to 528.9) ng ml(-1)) (P=0.005), and the babies of mothers who received antenatal steroids had significantly lower resistin levels ((n=44); 20.8 (5.5 to 159.9) ng ml(-1)) than the babies of mothers who did not ((n=66); 34.6 (7.2 to 568.4) ng ml(-1)) (P=0.015). There were significant correlations between resistin and IL-6 levels and between IL-6 and procalcitonin and CRP levels in babies whose mothers did not receive antenatal steroids. However, no correlation was found between these parameters in babies whose mothers received antenatal steroids. CONCLUSION Preterm delivery and PPROM involve complex cascade of events including inflammation, and steroids are potent anti-inflammatory agents. Elevated resistin levels in babies with PPROM and suppressed levels in babies whose mothers received antenatal steroids reported in this study might have been observed as a result of the effects of fetal inflammation on resistin levels.

Abstract
Although congenital diaphragmatic hernia is one of the most common congenital anomalies, complete bilateral agenesis of the diaphragm is a very rare congenital malformation and frequently associated with other major anomalies. We report a case of bilateral diaphragmatic agenesis associated with major congenital anomalies. A 2,240-g male infant was born at 35 weeks of gestation to a 34-year-old mother with a history of minimal prenatal care. Polyhydramnios was reported on prenatal level 1 scan. The patient experienced early respiratory distress requiring intubation. Apgar scores were 2/1/1 at 1, 5 and 20 minutes, respectively, and efforts to resuscitate him were unsuccessful. He died at 2 hours of age. Autopsy revealed bilateral diaphragmatic agenesis associated with right pulmonary hypoplasia, left pulmonary agenesis, multiple cardiac abnormalities and gallbladder agenesis. Cytogenetic studies showed normal male karyotype. Bilateral agenesis of the diaphragm is a life-threatening malformation. Survival of these infants often depends on cardiopulmonary function. Bilateral agenesis of the diaphragm associated with gallbladder and unilateral pulmonary agenesis is a rare entity, and its clinical significance needs further investigation.

Abstract
OBJECTIVE To evaluate the effects of addition of human milk (HM) fortifier and iron on the anti-infective properties of HM. STUDY DESIGN HM samples were collected from 28 lactating mothers who delivered prematurely, within the first week of post-natal life. HM fortifier Eoprotin was used. The effects of this fortifier against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans were evaluated using a filter paper method. The measurements were repeated with pure HM, fortified HM and iron-added HM. RESULTS HM inhibited the growth of S. aureus, E. coli, P. aeruginosa and Candida. Addition of HM fortifier did not result in any significant difference on this effect. The addition of iron to HM reduced antimicrobial effect against all three bacteria and the Candida. CONCLUSION Premature HM has strong antimicrobial activity and addition of the milk fortifier Eoprotin does not change this effect, but addition of iron reduces this antimicrobial activity.

Abstract
OBJECTIVE To evaluate the frequency of 5 mutations and their relationship with the Tel Hashomer criteria in 85 FMF patients. METHODS We looked for mutations in the Mediterranean fever (MEFV) gene in 84 consecutive patients who admitted to the Department of Medical Genetics of Afyon Kocatepe University, with a variable (from high to low) clinical suspicion of FMF. By using polymerase chain reaction and Hybridization-ELISA methods, 5 mutations (M694V, M694I, V726A, M680I and E148Q) have been studied between December 2002 and January 2005. RESULTS We detected homozygote mutations in 12 patients (25.3%) and heterozygote mutations in 23 patients (48.9%) out of 47 patients with high clinical suspicion of FMF using Tel Hashomer criteria. In 12 patients (25.3%), no mutation was detected despite the clinical diagnosis of FMF was likely according to the Tel Hashomer clinical criteria. On the other hand, we detected homozygote mutations in 2 patients (5.4%) and heterozygote mutations in 17 patients (45.9%) out of 37 patients with low clinical suspicion of FMF using Tel Hashomer criteria. In 18 out of 37 patients (48.6%) in this group no mutation was detected. CONCLUSION In patients with high or low clinical suspicion of diagnosis of FMF according to Tel Hashomer criteria, the frequency of homozygote patients was significantly higher than the frequency of patients with no mutation, but it was not higher than the frequency of heterozygote patients.

Abstract
Neuroendocrine complications are among important and frequently missed complications of traumatic brain injury. Hypopituitarism, the partial or complete insufficiency of anterior pituitary secretion may be underrecognized due to its subtle clinical manifestations in traumatic patients. We report a case of 14.5-year-old girl who was admitted due to growth failure and had been diagnosed to have multiple hypophyseal hormone deficiency including thyroid-stimulating hormone, gonadotropins, adrenocorticotropin hormone which developed years after traumatic head injury.

Abstract
Severe hypoglycaemia requiring more than 20 mg/kg per minute glucose infusion was seen in a premature infant. The infant was born to a woman with active tuberculosis, and she was on prophylactic isoniazid. Discontinuation of isoniazid resulted in prompt recovery of hypoglycaemia. Further pharmacological studies may be needed to establish a cause and effect relationship.

Abstract
Intrauterine growth curves should be specific to each population and are needed for the Turkish population. An analysis of birthweight, crown-heel length, and head circumference in newborns between 25 and 42 weeks of gestational age was made. A total of 2481 babies were evaluated. Mean, standard deviation, and percentile values were calculated for each gestational age and smoothed curves were obtained for each parameter. In our country, the use of these new curves is more appropriate than those obtained in other countries.

Abstract
BACKGROUND Transient tachypnea of the newborn (TTN) is usually a benign self-limiting respiratory disorder in the immediate neonatal period. The lipophilic surfactant-associated protein B (SP-B) was demonstrated to be the most relevant structural component of the surfactant system for immediate postnatal pulmonary adaptation. We hypothesized genetic variations of surfactant protein B (heterozygous 121 ins 2 mutation er intron 4 polymorphisms) to be related to TTN. PATIENTS AND METHOD We screened genomic DNA of 83 healthy term neonates (gestational age: 39 (37 - 41) completed weeks [median and range]; birth weight: 3325 +/- 541 grams [mean +/- SD]) and 75 infants presenting with TTN (gestational age: 38 (37 - 41) completed wecks [median and range]; birth weight: 3091 +/- 435 grams [mean +/- SD]) by means of PCR-amplification, fragment length and sequence analysis. TTN was diagnosed an the basis of the clinical signs with respiratory rate > 60 breaths/minute, fraction of inspired oxygen > 0.21, and characteristic radiographic findings within less than 24 hours after birth. Newborns with any infection, pulmonary or cardiac congenital malformations, postnatal asphyxia and infants born to diabetic mothers were excluded. RESULTS In TTN-group the frequency of male infants (68.4 % versus 44.6 %, p < 0.05) and caeserian section were significantly higher (68.4 % versus 30.1 %, p < 0.05). We did not find any statistical difference in frequency of intron 4 variations between controls and TTN-group (8.4 % versus 10.7 %). None of the infants were heterozygous for the 121ins2 SP-B mutation. CONCLUSIONS WC conclude polymorphisms of intron 4 and heterozygous 121 ins 2 mutation not to associated with TTN.
