Background Breast milk is preferred for the feeding of very low-birth-weight (VLBW) infants, but it does not meet nutrition requirements unless it is fortified. Adequate protein intake to maintain the growth of preterm infants cannot be provided by standard fortification methods because of variation in the protein content of human milk. Individualization is necessary to achieve target protein intakes. The goal of this study was to compare the effects of 2 different methods of individualized protein fortification of breast milk on the early growth of VLBW preterm infants. Methods In a prospective observational study, VLBW preterm infants ≤32 weeks of gestational age were randomized into 2 groups according to the method of breast milk fortification. Anthropometric measurements were performed in both groups weekly for 4 weeks to compare their growth. Results During the trial period, the daily protein intake (targeted vs adjustable fortification groups) was (median [range]) 4.5 (4.4-4.6) vs 4.01 (3.5-4.4) g/kg/d (P = 0.001); the daily weight gains (g/d and g/kg/d; mean ± SD) were 25.7 ± 3.9 vs 22.2 ± 6.4 g/d (P = 0.048) and 23.1 ± 4.3 vs 18.7 ± 4.3 g/kg/d (P = 0.014); and the weekly increase in head circumference was 9.8 ± 1.5 vs 8.4 ± 2.1 mm/wk (P = 0.040). All parameters were significantly higher in the targeted than the adjustable fortification group. Conclusions Individualized protein fortification using the targeted method for VLBW preterm infants had more positive effects on short-term growth compared with the adjustable fortification method.

Transient hypothyroxinaemia of prematurity (THOP) is a disorder encountered especially in extremely low birth weight and preterm newborns. In recent years, the survival rates of these babies have increased, owing to the advances in neonatal care, thereby increasing the incidence of THOP. Controversies about the management of this disorder still continues while accompanying morbidites may create difficulties in the treatment of these patients. A preterm baby boy, born at 256/7 gestational week with a birthweight of 665g who developed short bowel syndrome after necrotizing enterocolitis surgery and who was treated with rectal levothyroxine, is presented.

Holoprosencephaly is a complex brain malformation caused by the inability of the prosencephalon to divide to form the cerebral hemispheres. Central diabetes insipidus (CDI), as a result of a defect in vasopressin release, may be seen due to the abnormal hypothalamic infundibular region. CDI developing secondary to holoprosencephaly in the early neonatal period has rarely been reported in the literature. A case of early-onset CDI with holoprosencephaly and 13q deletion is presented.

Context: Limited data are available on the exact incidence of disorders of sex development (DSD) with genital ambiguity at birth. Objective: To determine frequency of ambiguous genitalia in newborns. Design: Prospective multicenter study. Setting: Three tertiary care hospitals. Patients or Other Participants: All 14,177 babies born during the study period were included. Main Outcome Measures: All newborns were examined at birth; data on weeks of gestation, birth weight, and length were collected. A structured questionnaire was used for data collection. Quigley and Prader scales were used for phenotypic grading. Clinical and genetic investigations were performed. Results: Eighteen babies with ambiguous genitalia were found among 14,177 newborns (1.3/1000). Fifteen newborns had 46, XY DSD, one had 46, XX congenital adrenal hyperplasia, and one had 45, X/46, XY mixed gonadal dysgenesis. Karyotype analysis was not done in one baby who died in the neonatal period. The ratio of prematurity was higher in the DSD group (44% vs 11%; P < 0.001) and the ratio of small for gestational age was also higher in the DSD group (22% vs 5%; P = 0.007). Eight babies with DSD had mothers who had additional medical conditions, such as preeclampsia, depression, insulin resistance, and gestational diabetes mellitus. Conclusion: The frequency of ambiguous genitalia was higher than in previous studies, but, as with any experiment, the finding should be met with caution because this study was conducted in tertiary care hospitals. In addition, lower birth weight in the DSD group supports the hypothesis that early placental dysfunction might be important in the etiology of male genital anomalies.

WOS: 000484450300023, PubMed ID: 31236036, Hyperglycemia has become an important risk factor for mortality and morbidity in the neonatal period, especially with increased survival rates of very low birth weight neonates. Hyperglycemia in the neonatal period develops as a result of various mechanisms including iatrogenic causes, inability to supress hepatic glucose production, insulin resistance or glucose intolerance, specifically in preterm neonates. Initiation of parenteral or enteral feeding in the early period in preterm babies increases insulin production and sensitivity. The plasma glucose is targeted to be kept between 70 and 150 mg/dL in the newborn baby. While a blood glucose value above 150 mg/dL is defined as hyperglycemia, blood glucose values measured with an interval of 4 hours of >180-200 mg/dL and +2 glucosuria require treatment. Although glucose infusion rate is reduced in treatment, use of insulin is recommended, if two blood glucose values measured with an interval of 4 hours are >250 mg/dL and glucosuria is present in two separate urine samples.

Low levels of SHBG have become a marker for insulin resistance and diabetes. Babies born to mothers who are obese, have diabetes, or smoke during pregnancy are at greater risk of developing obesity and diabetes later in life.To examine the impact of maternal obesity, diabetes and smoking on SHBG levels in newborns.This cross-sectional study is part of an ongoing multicenter, longitudinal study.98 healthy newborns and their parents, including 16 mothers with diabetes and 31 mothers with a smoking history.Cord blood and second day venipuncture samples were collected for measurement of SHBG and insulin.Babies born to mothers with diabetes had lower SHBG levels in cord blood [14.0 (8.9-20.4) vs. 19.6 (14.9-25.1) nmol/L; p=0.011] and on day 2 [18.8 (12.6-21.2) vs. 22.9 (17.1-29.1) nmol/L; p=0.015] than controls. Maternal diabetes remained negatively associated with SHBG levels in cord blood (p=0.02) and on day 2 (p=0.04) when adjusted for mothers' age, smoking status, pre-pregnancy weight and weight gain during pregnancy. SHBG levels in cord blood and day 2 samples were similar in babies born to mothers who were overweight-obese but not diabetic vs. normal weight, or were smokers when compared to non-smokers.SHBG levels are lower in newborns born to mothers with diabetes than without diabetes, and may be a marker for babies' life-long risk for abnormal metabolic health. On the other hand, the adverse effects of tobacco smoke on the fetus do not appear to directly influence SHBG levels.Low levels of SHBG have become a marker for insulin resistance and diabetes.

Background: healthcare-acquired infections (HAIs) in the neonatal period cause substantial morbidity, mortality, and healthcare costs. Our purpose was to determine the prevalence of HAIs, antimicrobial susceptibility of causative agents, and the adaptivity of the Centres for Disease Control and Prevention (CDC) criteria in neonatal HAI diagnosis. Methods: a HAI point prevalence survey was conducted in the neonatal intensive care units (NICUs) of 31 hospitals from different geographic regions in Turkey. Results: the Point HAI prevalence was 7.6%. Ventilator-associated pneumonia (VAP) and central line-associated bloodstream infections (CLABSI) and late onset sepsis were predominant. The point prevalence of VAP was 2.1%, and the point prevalence of CLABSI was 1.2% in our study. The most common causative agents in HAIs were Gram-negative rods (43.0%), and the most common agent was Klebsiella spp (24.6%); 81.2% of these species were extended spectrum beta-lactamase (ESBL) (+). Blood culture positivity was seen in 33.3% of samples taken from the umbilical venous catheter, whereas 0.9% of samples of peripherally inserted central catheters (PICCs) were positive. In our study, 60% of patients who had culture positivity in endotracheal aspirate or who had purulent endotracheal secretions did not have any daily FiO2 change (p = 0.67) and also 80% did not have any increase in positive end-expiratory pressure (PEEP) (p = 0.7). On the other hand, 18.1% of patients who had clinical deterioration compatible with VAP did not have endotracheal culture positivity (p = 0.005). Conclusions: neonatal HAIs are frequent adverse events in district and regional hospitals. This at-risk population should be prioritized for HAI surveillance and prevention programs through improved infection prevention practices, and hand hygiene compliance should be conducted. CDC diagnostic criteria are not sufficient for NICUs. Future studies are warranted for the diagnosis of HAIs in NICUs., NA

Introduction There is limited information about problems of feedback inhibition of lactation which should be considered as a rare cause of breast engorgement. We report the management of excessive breast engorgement in a mother with a presumptive diagnosis of a defect in the feedback inhibition of lactation. Main issue The participant, who had been discharged on postpartum Day 2 while breastfeeding her infant, was readmitted to the hospital the next day with engorgement of the breasts and cessation of milk flow. Pumping and application of cold dressings alone did not work effectively. The severity of the symptoms decreased only after the addition of an anti-inflammatory drug and a prolactin inhibitor. Management The participant received breastfeeding counseling, family-centered care, and support for pumping equipment. An anti-inflammatory drug was started and a low dose prolactin inhibitor was given. The difficulty was the management of extensive and painful breast engorgement and the re-establishment of milk flow. At postpartum Day 14, the participant and her infant were discharged with effective breastfeeding status. Conclusions The recognition of a problem in the feedback inhibition of lactation as a cause of breast engorgement is important because it may be unresponsive to classical treatment methods resulting in cessation of milk flow. With the cautious use of low-dose cabergoline, in addition to other treatment strategies, milk flow can be reduced in a controlled manner while ensuring the continuity of milk production. An early diagnosis, interdisciplinary approach, and a close follow-up of the mother–infant pair are essential for preserving lactation.

Background: SHBG levels are low in obesity, and low SHBG levels are a biomarker for the development of T2DM and the metabolic syndrome. We sought to determine whether low SHBG in newborns will predict childhood obesity. Methods: We studied 94 healthy, singleton, full-term newborns, and measured their length, weight (BW), waist circumference, and skinfold thicknesses. We collected cord blood as well as day 2 venous blood samples for the measurement of SHBG and insulin (ALPCO, Salem NH). Maternal age, pre-pregnancy weight, pregnancy weight gain, and glucose screening test results were obtained from obstetrical records. Mothers with chronic diseases were excluded from the study. When babies were 2 years old, we administered a questionnaire to collect information about their eating, sleeping, screen viewing habits, and anthropometric measurements at ages 6, 12, and 24 months (n=47). Overweight was defined as a BMI SDS of ≥1 and

Renal vein thrombosis in a neonate is a rare but well recognized condition with low mortality but high morbidity. The cause has not been explained clearly yet but is probably a multifactorial process that includes inherited prothrombotic abnormalities. Antenatal onset of renal vein thrombosis is important due to the increased risk for permanent organ damage. We report a case of prenatal thrombosis of the renal veins and the inferior vena cava in a newborn with double heterozygosity for factor V Leiden and prothrombin gene mutations who had persistently impaired renal function requiring chronic peritoneal dialysis.

RSV is one of the most important agents of lower respiratory infections in childhood. In this study, anti-RSV antibody levels in mother-infant pairs and factors related to antibody transfer ratio were investigated. One hundred and twenty-seven women that had term babies and their babies and 84 mother-infant pairs of them who continued the study after 6 months were enrolled. Anti-RSV IgG antibodies of the mothers and infants were positive in 46.5% and 61.5%, respectively. At the sixth month, anti-RSV antibodies were negative in all infants. Median of the anti-RSV antibody levels of the mothers and infants at birth were 12.08 IU/ml (1.21–119.27) and 13.78 IU/ml (3.99–108.6), respectively. There was a significant correlation between anti-RSV antibody levels of mothers and infants at birth (p: 0.0001, r: 0.667) and anti-RSV antibody levels of infants at birth and at 6th month (p: 0.0001, r: 0.343). Median ratio of infant and mother antibody levels was 1.22 (0.14–6.05). Median ratio that was detected in appropriate for gestational age infants was significantly higher than in small for gestational age or large for gestational age infants. In this study, the significant positive correlation between maternal antibody levels and infants’ antibody levels at birth suggests that maternal vaccination strategies may be logical. We showed that antibody transfer rate was highest in appropriate for gestational age infants. It should be kept in mind that maternal vaccination strategies may be less effective in small for gestational age and large for gestational age infants.

Jaundice is one of the most common problems in the newborn. It is generally accepted as a physiologic condition; most cases are benign and transient. However, in a small portion of jaundiced newborn infants, serum bilirubin concentrations increase to a level at which irreversible brain damage can occur. The timely diagnosis and management of severe hyperbilirubinemia is essential to prevent acute bilirubin encephalopathy and kernicterus. Kernicterus still occurs although it is almost always preventable. The focus of this guideline is to reduce the incidence of severe hyperbilirubinemia and bilirubin encephalopathy. Therefore, a system-based approach using the recommendations of this guideline should be implemented in all birthing facilities and continued in ambulatory care of the newborn infants. / Sarılık yenidoğan bebeklerde sık görüllen bulgulardan biridir. Normal fizyolojik bir durum olarak kabul edilir; genellikle selim, geçici bir durumdur. Ancak yenidoğanların küçük bir bölümünde geri dönüşümsüz ciddi beyin hasarı için tehdit oluşturabilen düzeylere erişebilir. Zamanında tanı konup tedavi edildiğinde akut bilirubin ensefalopatisi ve kernikterus önlenebilir. Kernikterus her zaman önlenebilir bir durum olmasına rağmen halen görülmektedir. Bu kılavuzun amacı ciddi hiperbilirubinemi sıklığını ve bilirubin ensefalopatisini azaltmaktır. Bundan dolayı bu kılavuzun önerilerinin tüm doğum yapılan kurumlarda ve taburcu etme sonrası izlemde kullanılmasını sağlamak önemlidir., NA

Ince Z, Bulut O, Tugrul-Aksakal M, Unuvar A, Devecioglu O, Coban A. Asymptomatic intracranial hemorrhage in a newborn with congenital factor VII deficiency and successful treatment with recombinant activated factor VII. Turk J Pediatr 2018; 60: 562-565. Intracranial hemorrhage is considered the most common cause of death in newborns with congenital factor VII (FVII) deficiency. Recombinant activated FVII (rFVIIa) provides specific replacement therapy, however there is limited experience with its neonatal use. We describe our experience about the treatment of intracranial hemorrhage in a newborn with congenital FVII deficiency and emphasize the importance of imaging in asymptomatic patients. She presented with ecchymoses on her skin, no other pathological clinical signs, prolonged PT, normal PTT and FVII activity of 2%. Intracranial hemorrhage was diagnosed while screening for internal bleedings. Treatment with rFVIIa resulted in stabilization and regression of the hematoma.

Background Human milk is the optimal source of nutrition for preterm infants. However, breast milk alone is often not sufficient to satisfy the high nutritional needs for growth and development in preterm infants. Fortified human breast milk is the best way to meet the nutritional needs of preterm infants. Human breast milk is fortified according to the estimated nutrient content of mature breast milk; however, because the content of breast milk is highly variable, the macronutrient support may be more or less than needed. The goal of this study was to analyze the macronutrient content of preterm human milk during the first 6 weeks of lactation. Methods The study included 32 mothers of preterm infants with a gestational age of ≤32 weeks. Breast milk was collected in 24-h cycles and analyzed daily using mid-infrared (MIR) spectroscopy. We measured protein, fat and lactose concentrations in the breast milk, and the energy content was calculated. Results The protein content was high during the first weeks of lactation, but decreased as lactation progressed. The fat, energy and lactose contents of the breast milk were low during the first 2 weeks of lactation, increased as lactation progressed and remained constant thereafter. In women with high body mass index (BMI), higher protein levels were found in transitional milk. In women who had high income level, higher fat and energy levels were found in transitional milk. Conclusion Our findings indicate that the macronutrient content of preterm breast milk changes throughout the course of lactation, with BMI and income level. Knowledge of the macronutrient composition of breast milk is necessary to ensure that preterm infants receive the appropriate types and quantities of nutrients to promote optimal growth, and to ensure that breast milk is fortified according to individual needs. Our findings may be useful for the provision of optimal nutritional support for preterm infants.

Schinzel-Giedion syndrome (SGS) is a rare autosomal dominant disorder that results in facial dysmorphism, multiple congenital anomalies, and an increased risk of malignancy. Recently, using exome sequencing, de novo heterozygous mutations in the SETBP1 gene have been identified in patients with SGS. Most affected individuals do not survive after childhood because of the severity of this disorder. Here, we report SETBP1 mutation confirmed by molecular analysis in a case of SGS with congenital megacalycosis.

To determine the incidence of vancomycin-resistant enterococcus (VRE) colonization in our neonatal intensive care unit (NICU) over five-year period, rate of progression to VRE infection and associated risk factors.A retrospective analysis of a prospective surveillance for VRE colonization and health care-associated infections was made. Contact precautions were taken against colonization, although the application varied over the years due to repairs in the unit.VRE rectal colonization was detected in 200/1671 neonates (12%) admitted to NICU. It showed great interannual variability from 1.9% to 30.3%. Sytemic VRE infection developed in 6/200 VRE-colonized patients (3%) within a median of 9 days (range: 3-58 days). The risk factors for VRE infection development identified in the univariate analysis were long hospital stay (≥30 days), necrotizing enterocolitis, surgical procedure, extraventricular drainage, receipt of amphotericin B and receipt of glycopeptides after detection of VRE colonization. Crude in-hospital mortality was higher in neonates who developed a systemic VRE infection (p 0.001).Maintaining physical conditions in the unit favorable for infection control and rational use of antibiotics are essential in the control of VRE colonization and resultant infections. Special attention should be directed to VRE-colonized babies carrying the risk factors.

Mother-to-child transmission of human immunodeficiency virus (HIV) can be prevented by prenatal, perinatal and postnatal interventions. Although the incidence of HIV infection in Turkey is low, the number of cases are increasing in years. The aim of this study was to evaluate the characteristics of infants with HIV-positive mothers followed in a pediatric HIV center in Istanbul, Turkey and to describe the vertical transmission of HIV infection among the cases. Clinical and laboratory features of HIV-infected mothers and their exposed infants, followed in our department between June 2007 and February 2015 were retrieved from medical records retrospectively. The data about HIV infection and pregnancy course were confirmed with medical records when possible otherwise based on mothers' self-reports. Clinical and laboratory data about the birth and after birth of the babies in the other centers were obtained from the related centers. A total of 32 HIV-exposed infants (18 female, 14 male) were followed in eight years. HIV infection could be diagnosed in 15 (46.9%) mothers before pregnancy, in 10 (31.3%) during pregnancy and in seven (21.8%) during delivery. Nine of the mothers (28.1%) did not receive antiretroviral therapy during pregnancy. The median age for the patients at the admission were 13.5 days in which the earliest was a day and the latest was 420 (14 months) days. Three of the infants were fed with breast milk. Four infants (12.5%) did not receive antiretroviral prophylaxis. Cotrimoxazol prophylaxis were given approximately to 60% (n= 19) of the infants starting from 4-6 weeks. HIV viral load could be tested within the first 48 hours among 20 infants and except one, all was found as negative. A total of two infants (6.2%) were infected with HIV and their initial viral loads were 89.500 and 87.500 copies/ml, respectively. One of the infant was delivered vaginally and his mother's HIV status was detected during delivery. The mother of other infected infant was diagnosed only three weeks before birth and delivered with cesarean section. Both mothers had high viral loads just before delivery (> 102.000 and 67.000 copies/ml, respectively). One of the infants infected with HIV died in the 4(th) month due to pulmonary infection and sepsis. This study reveals a high rate of perinatally transmitted HIV infection and mortality. The limited number of cases involved in this one-center study should be taken into account while interpreting this result. All pediatric HIV centers in Turkey should work as partners for more precise national results. Nevertheless, our results draw attention to the lack of prenatal follow-up evaluation in women. In particular, the prompt diagnosis of HIV infection in pregnancy should be provided or not to be missed and follow-up of pregnant women with HIV should be carried out by specialist centers.

Key Clinical Message We report the occurrence of supraventricular tachycardia during intravenous immunoglobulin (IVIG) infusion. Supraventricular tachycardia was observed in two newborn patients during IVIG infusion. Both of the babies responded to adenosine treatment. Cardiorespiratory monitoring during IVIG infusion can be recommended because of the possibility of this potentially lifethreatening adverse effect.

While optimal antenatal care is provided for the mother to improve survival of newborn babies, appropriate should be given to the babies. The most important time period in delivery room management is the first minute which is named as “first golden minute”. Within this period, body temperature of the baby should be checked , patency of its airway, its respiratory and heart rate should be assesed, first breath should be initiated in case of need, and saturation must be measured objectively using a pulse oximeter. Excessive and unnecessary use of oxygen should be prevented by considering targeted saturation values which are determined according to the time passed after birth. Recent studies showed that 30-60 seconds delay in umbilical cord clamping time will lead to higher hemoglobin concentrations and iron stores in newborns. Preterm babies who may need ventilatory support should be put on continuous positive airway pressure (CPAP) even from the first breath which will decrease the need for intubation and surfactant administration. Prophylactic administration of surfactant in preterm newborns is being abandoned today, surfactant should only be given to preterm newborns in need. Nowadays, less invasive administration of surfactant (LISA) is being tested. If resuscitation is needed oxygen support should be started with 21% saturated oxygen in newborns at or above 35th gestational age. If the gestational age is less than 35th weeks, 21-30% saturated oxygen should be given at the beginning then, oxygen support should be increased up to targeted saturation levels in a controlled manner.

Hypoglycemia is one of the most important and most common metabolic problems of the newborn because it poses a risk of neurological injury, if it is prolonged and recurs. Therefore, newborns who carry a risk of hypoglycemia should be fed immediately after delivery and the blood glucose level should be measured with intervals of 2-3 hours from the 30th minute after feeding. The threshold value for hypoglycemia is 40 mg/dL for the first 24 hours in symptomatic babies. In asymptomatic babies, this value is considered 25 mg/dL for 0-4 hours, 35 mg/dl for 4-24 hours, 50 mg/dL after 24 hours and 60 mg/dL after 48 hours. Screening should be performed with bed-side test sticks. When values near the limit value are obtained, confirmation with laboratory method should be done and treatment should be initiated, if necessary. The level targeted with treatment is considered 50 mg/dL in the postnatal first 48 hours before feeding, 60 mg/dL after 48 hours in babies with high risk and above 70 mg/dL in babies with permanent hypoglycemia. In cases in which the blood glucose level is below the threshold value and can not be increased by feeding, a glucose infusion of 6-8 mg/kg/min should be initiated. If symptoms accompany, a mini bolus of 10% dextrose (2 ml/kg/min) should accompany. Incements (2 mg/kg/min) should be performed, if the target level can not be achieved and decrements (2 ml/kg/ min) should be performed, if nutrition and stabilization is provided. The infusion should be discontinued, if the infusion rate decreases to 3-5 mg/ kg/min. If necessary, blood samples should be obtained during hypoglycemia in terms of differential diagnosis and the investigation should be performed following a 6-hour fasting period in babies fed enterally and at any time when the plasma glucose is 60 mg/dL following a 6-hour fast. © 2018 by Turkish Pediatric Association.

Bronchopulmonary dysplasia (BPD) remains an important complication of preterm births. The soluble form of ST2 (sST2), interleukin-33 (IL-33), and soluble form of the urokinase plasminogen activator receptor (suPAR) have attracted increasing attention as biomarkers for different diseases. The aim of the current study was to assess the predictive value of plasma sST2, IL-33, and suPAR levels in patients with risk of BPD development.A total of 38 babies were studied prospectively on delivery to the neonatal intensive care unit. Serum levels of IL-33, sST2, and suPAR were measured using enzyme-linked immunosorbent assay. Serum samples were collected from umbilical cord (at the time of delivery, termed CB) and peripheral blood (on day 14, termed PB).Levels of suPAR (PB-suPAR) and sST2 (PB-sST2) in the peripheral blood of the BPD group were significantly higher than the corresponding levels in the non-BPD group (P0.001, P = 0.028, respectively. There was a statistically significant correlation between PB-suPAR levels and the severity of BPD (P0.001)) when the suPAR results were analyzed using the receiver operating characteristic curve.PB-suPAR and PB-sST2 levels are sensitive and specific independent predictive biomarkers in preterm babies with BPD.

Aim: To assess the clinical features, diagnosis, treatment and prognosis of newborn infants with a diagnosis of Vein of Galen Malformation (VGAM)during a 10-year period. Method: Eight patients with a diagnosis of VGAM in the neonatal period were assessed retrospectively in terms of clinical signs, diagnosis, treatment strategies and follow-up. Three of four patients who survived had neurological assessment whereas one was lost to follow-up because of moving to another city. Results: Seven of 8 patients had an antenatal diagnosis. In all cases, severe heart failure and pulmonary hypertension were present from the first day of life and hypotension, multiorgan failure, hydrocephaly and seizures developed in the following days. VGAM and its feeder arteries were mapped by cranial magnetic resonance imaging and magnetic resonance angiography. Transarterial embolization therapy was performed on 7 patients, of whom four babies survived and three babies died, while one patient died before any intervention. Conclusion: The mortality and morbidity rates of VGAM is high because of its mixed anatomy, pathophysiology and characteristic features leading to severe neurological sequelae in the survivors. Prognosis in high risk neonates can be improved with aggressive medical support and early endovascular embolization therapy.

Objective: To determine exposure to endocrine-disrupting phthalates in preterm infants in neonatal intensive care units (NICU). Methods: Urine samples (n=151) from 36 preterm infants (

Background: Little is known about factors associated with carbapenem-resistant Klebsiella pneumoniae infections in pediatric patients, who are initally colonized with carbapenem-resistant Klebsiella pneumoniae. Materials and methods: A retrospective case–control study was conducted involving pediatric and neonatal intensive care units throughout a five-year period (January 2010–December 2014). Clinical and microbiological data were extracted from Hospital Infection Control Committee reports and patients’ medical records. Risk factors were assessed in carbapenem-resistant Klebsiella pneumoniae colonized patients who developed subsequent systemic infection (cases) and compared to carbapenem-resistant Klebsiella pneumoniae colonized patients who did not develop infection (controls). Results: Throughout the study period, 2.6% of patients admitted to neonatal intensive care units and 3.6% of patients admitted to pediatric intensive care units had become colonized with carbapenem-resistant Klebsiella pneumoniae. After a mean of 10.6 ± 1.9 days (median: 7 days, range: 2–38 days) following detection of colonization, 39.0% of the carbapenem-resistant Klebsiella pneumoniae colonized patients in pediatric intensive care units and 18.1% of carbapenem-resistant Klebsiella pneumoniae colonized patients in neonatal intensive care units developed systemic carbapenem-resistant Klebsiella pneumoniae infection. Types of systemic carbapenem-resistant Klebsiella pneumoniae infections included bacteremia (n = 15, 62.5%), ventilator-associated pneumonia (n = 4, 16.6%), ventriculitis (n = 2, 8.3%), intraabdominal infections (n = 2, 8.3%), and urinary tract infection (n = 1, 4.1%). A logistic regression model including parameters found significant in univariate analysis of carbapenem resistant Klebsiella pneumoniae colonization and carbapenem resistant Klebsiella pneumoniae infection groups revealed underlying metabolic disease (OR: 10.1; 95% CI: 2.7–37.2), previous carbapenem use (OR: 10.1; 95% CI: 2.2–40.1), neutropenia (OR: 13.8; 95% CI: 3.1–61.0) and previous surgical procedure (OR: 7.4; 95% CI: 1.9–28.5) as independent risk factors for carbapenem-resistant Klebsiella pneumoniae infection in patients colonized with carbapenem-resistant Klebsiella pneumoniae. Out of 24 patients with carbapenem resistant Klebsiella pneumoniae infection, 4 (16.6%) died of carbapenem-resistant Klebsiella pneumoniae sepsis. Conclusion: Asymptomatic colonization with carbapenem-resistant Klebsiella pneumoniae in intensive care units of pediatric departments should alert health care providers about forthcoming carbapenem-resistant Klebsiella pneumoniae infection. Those carbapenem-resistant Klebsiella pneumoniae colonized patients at risk of developing infection due to carbapenem-resistant Klebsiella pneumoniae may be targeted for interventions to reduce subsequent infection occurence and also for timely initiation of empirical carbapenem-resistant Klebsiella pneumoniae active treatment, when necessary.

Nonphysiologic hyperbilirubinemia of unexplained cause is prevalent among Turkish newborns, suggesting that there might be genetic risk factors in this population. Mutation of the UGT1A1 gene, glycine to arginine at codon 71 (G71R), is related to the development of neonatal jaundice in East Asian populations but the frequency of this mutation is rare among Caucasian populations. There are insufficient data on the G71R mutation in Turkish newborns with hyperbilirubinemia. The aim of this study was to investigate the genotypic distribution of the G71R mutation and its relationship with nonphysiologic hyperbilirubinemia of unexplained cause in Turkish newborns.Polymerase chain reaction, restriction fragment length polymorphism and agarose gel electrophoresis techniques were used for detection of G71R mutation in 109 newborn infants: 39 with hyperbilirubinemia and 70 without hyperbilirubinemia.The genotypic distribution for the mutation was 70 G/G, 32 A/G, 7 A/A genotypes and the mutated allele frequency was 0.22. The frequency of G71R mutation was 33.3 % (n = 13) A/G, 7.7% (n = 3) A/A in the hyperbilirubinemia group and 27.1% (n = 19) A/R, 5% (n = 4) A/A in the nonhyperbilirubinemia group. The difference between the groups was not statistically significant.Our results suggest that G71R mutation of UGT1A1 is not rare; however, an association between G71R mutation and hyperbilirubinemia of unexplained cause has not been shown in Turkish newborns.

Summary Background Premature born children may show insulin resistance in childhood which may be due to intrauterine or postnatal adverse environmental factors. Objective Aim of this study was to evaluate insulin resistance and body composition in preterm born children born appropriate for gestational age (AGA) or small for gestational age (SGA) and relations with IGF-I, IGFBP-3 axis. Methods Ninety-three preterm born children grouped as premature SGA (n = 30) and premature AGA (n = 63) were evaluated at age 4·6 ± 0·2 years and 4·7 ± 0·1 years with respect to their glucose, insulin, IGF-I, IGFBP-3, IGFBP-1, leptin levels and body composition by dual-energy X-ray absorptiometry. Their data were compared to that of body mass index (BMI) matched term SGA (n = 42) and term AGA (n = 44) children of age 4·5 ± 0·2 and 3·8 ± 0·1 years. All children had height appropriate for their target height. Insulin resistance was evaluated by basal insulin and homeostasis model assessment for insulin resistance (HOMA-IR). Results Basal insulin level was similar in preterm AGA (4·3 ± 1·4 pmol/l) and term AGA (7·9 ± 6·4 pmol/l) children at similar and normal BMI levels. Preterm SGA children had insulin levels (5·0 ± 3·6 pmol/l) similar to preterm AGA children but significantly lower than that in term SGA children (23·7 ± 20·8 pmol/l) (P = 0·001). Similar results were obtained for HOMA-IR. Term SGA children had also significantly lower IGFBP-1 levels. Body composition, leptin and IGFBP-3 did not differ between the respective groups. IGF-I was lower in preterm AGA (5·0 ± 0·6 nmol/l) than in term AGA (8·3 ± 1·2 nmol/l) (P

The aim of this study was to evaluate the effectiveness of different oral carbohydrate solutions for alleviation of pain in healthy preterm babies. Thirty-one preterm infants who were having blood drawn by heel prick were given 2 ml of solution A (20% sucrose), solution B (20% glucose) or solution C (placebo, sterile water) into the mouth, 2 min before lancing. Behavioural responses to this painful stimulus were measured by duration of crying and facial expressions (Neonatal Facial Coding System, NFCS) and physiological responses were measured by heart rate (HR), respiratory rate (RR), and oxygen saturation changes (SaO(2)). Infants had a mean birth weight (+/-SD) of 1,401 g (406), gestational age of 30.5 weeks (2.7); at the time of the procedure the postmenstrual age was 32.3 weeks (1.5). There was no significant difference in the time spent squeezing the heel between the three groups (P = 0.669). After the heel prick of both the sucrose and glucose groups the duration of first cry and total crying time was significantly reduced (P = 0.005 and P = 0.007). When the babies received placebo they showed a significantly higher NFCS score at 4 and 5 min after the heel prick (P = 0.009 and 0.046 respectively). Following painful stimulus HR increased significantly in the first 3 min compared with baseline, and at the first minute the mean of the HR was found to be significantly higher in the placebo group than in the sucrose and glucose groups (P = 0.007). We concluded that both sucrose and glucose administered orally before a heel prick reduce the pain response in preterm infants.

Even early life in utero cannot provide a safe place for newborns. The first acquaintance with chemicals takes place in utero and/or with mother's milk after delivery. Besides legislations and bans to persistent organic pollutants (POPs), these chemicals are still affecting the general population especially the children as they are one of the populations most susceptible to chemicals, and also the health problems may arise in the future. Our objective is to collect the first data in newborns in Turkey to determine baseline levels of POPs in the general population and estimate the potential cancer risk related to exposure. Twenty-nine organochlorine pesticides (OCPs) and 18 polychlorinated biphenyl (PCB) congeners in blood samples of newborn boys (0-1 month old) who were born in Istanbul, Turkey, in 2010-2012 were evaluated with high-resolution gas chromatography-high-resolution mass spectrometry (HRGC/HRMS). Results for analyzed chlorinated compounds are as follows: hexachlorocyclohexane (Sigma HCH) 1828 +/- 3650 pg/g lipid, dichlorodiphenyltrichloroethane (Sigma DDT) 10,000 +/- 15,398 pg/g lipid, and Sigma PCB 1068 +/- 1823 pg/g lipid. 4,4'-DDT, 4,4'-dichlorodiphenyldichloroethylene (4,4'-DDE), hexachlorobenzene, and PCB 138 and 153 are the major contaminants. New POPs as lindane 61 +/- 268 pg/g lipid, pentachlorobenzene 13 +/- 74 pg/g lipid, and endosulfan 29 +/- 106 pg/g lipid are also detected in blood. Estimated total risk for lifetime PCB exposure is less than 1 x 10(-5), an acceptable risk. Blood concentration levels will be important base data in the assessment of health concerns of newborns as well as for studies about how endocrine disruptors affect humans.

The human body is not a chemically uncontaminated system. Every simple action that humans undertake, such as drinking water, eating, nursing, and even breathing air, puts the system under environmental xenobiotic exposure stress. Environmental chemicals have been shown to produce unwanted effects on health and remove the right to healthy living, starting from the first encounter in utero to geriatrics, throughout the lifespan. Organochlorine pesticides (OCPs) and polychlorinated biphenyl (PCB) levels, important members of the persistent organic pollutants (POPs), have been detected before in human breast milk and also in the adipose tissue of women from different regions of Turkey; however, there was no information about the blood levels of these chemicals. This study generated the first information that evaluates OCP and PCB contamination levels in the blood of the women living in Turkey. The current study measured the blood concentrations of OCPs and PCBs in 58 healthy women (age 20-41 years; mean age 28 years) who were living in Istanbul, Turkey, in the years 2010-2012. Samples were analyzed for 29OCPs and 18 PCB congeners using high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS). PCB 153 was the predominant congener (643.2 pg/g lipid), followed by PCB 138 and PCB 180. 4,4'-DDE (24872.8 pg/g lipid) was the most common organochlorinated pesticide contaminant in studied blood samples. Results for analyzed chlorinated compounds were as follows: Sigma PCB 2682 +/- 3300 pg/g lipid; Sigma DDT 25,938+28,644 pg/g lipid; and Sigma HCH 2930 +/- 2222 pg/g lipid, respectively. The mean concentration of Sigma WHOPCB-TEQ was 0.037 pg/g on a lipid basis. This information will be important base data during the assessment of the general health concerns of women, as well as for studies about how endocrine disruptors affect humans for forthcoming studies.

The aim of this study was to investigate the possible relationship between cord bloodalpha-fetoprotein (AFP) level and development of subsequent neonatal hyperbilirubinemia.The term newborns born between March 2005 and October 2005 were included in the study. Infants with Coombs-positive ABO and/or Rh incompatibility and/or hemolytic jaundice, asphyxia, congenital anomaly and signs of bleeding were excluded from the study. Cord blood AFP levels were measured in 504 full term newborns in this period. Infants were followed-up for possible neonatal hyperbilirubinemia. The capillary bilirubin level (CBL) was examined expeditiously in newborns developing jaundice and in other infants at the time discharge while the screening test was being performed.The mean umbilical cord AFP level was 49.1 ± 44.9 mg/L (range 1.1-396.2 mg/L), mean CBL was 5.8 ± 3.1 mg/dL (range 1-19.4 mg/dL), and the mean bilirubin detection time was 37 ± 23.2 hours (range 12-144 h) of age. Although a significant positive correlation was found between umbilical cord AFP and CBL levels, it was weak (r = 0.187, p 0.001). Comparison of AFP levels in terms of bilirubin percentile values appropriate for postnatal age also showed a significant weak positive correlation (r = 0.113, p 0.001).The umbilical cord AFP levels may not be used as a strong predictor for the determination of newborns at risk for hyperbilirubinemia.

The objective of this study was to assess low-risk very low birth weight (VLBW) children, before the era of modern neonatal intensive care in Turkey, during adolescence. Forty-one VLBW adolescents were compared with 40 adolescents who had normal birth weight. The physical and neuromotor development, educational achievement and psychosocial status were assessed at a mean age of 17 +/- 1.6 years. VLBW adolescents were shorter than normal birth weight adolescents (p = 0.01). A major neurological abnormality (cerebral palsy) was seen in 12% and a minor neurological abnormality (tremor, coordination, behavioral and speech disorders) in 17%. VLBW adolescents had higher rates of visual problems (56% vs. 5%). School failure was present in 27%. There were no differences in behavioral problems or quality of life between the two groups, but VLBW adolescents did have a lower self-esteem score. Neurodevelopment and growth sequelae were a significant problem in VLBW adolescents. As early intervention might help to prevent or ameliorate potential problems, long-term follow-up is essential.

Background There are still controversies whether insulin resistance (IR) develops in preterm born children during early childhood. Objective To investigate the role of leptin, soluble leptin receptor (sOB-R), adiponectin, visfatin and insulin sensitivity in the pathogenesis of possible IR in preterm born children during early childhood. Patients and metods Twenty-nine preterm small for gestational age (SGA) born children (Group 1) and 25 preterm appropriate for gestational age (AGA) born children (Group 2), matched for gestational age and sex were included in the study. Mean chronological age at investigation was 3.3 ± 0.7 years and not different between the groups. Blood samples for fasting blood glucose, insulin, proinsulin, adiponectin, leptin, sOB-R and visfatin were obtained. Results Mean height and weight standard deviation scores (SDS) at investigation were significantly lower in Group 1 than in Group 2, but there was no significant difference in body mass index (BMI) SDS between the groups. Catch-up growth (CUG) was higher in Group 1 than in Group 2. There was no difference regarding homeostasis model assessment for IR (HOMA-IR), leptin, sOB-R, adiponectin, proinsulin and visfatin values between the groups. In the whole group, log visfatin showed a negative correlation with Δweight SDS. There was a positive correlation between HOMA-IR and BMI SDS. Adiponectin levels showed a positive correlation with log visfatin levels in all groups. Conclusion Preterm born children whether AGA or SGA do not show IR in early childhood if BMI is normal. Significant differences between the preterm SGA and preterm AGA groups regarding the adipocytokine levels were not detected.

To collect data towards the establishment of a guideline to predict the population under risk for the development of retinopathy of prematurity (ROP) in Turkey.Medical reports of 2950 preterm infants who underwent screening examinations for ROP between 1996 and 2010 at Istanbul Faculty of Medicine, Department of Ophthalmology were reviewed. The study population was classified as inpatient infants and referred infants. A risk factor analysis was performed limited to the 788 inpatient infants. The demographical variables regarding birth weight (BW), gestational age (GA) and postnatal age at the time of treatment were compared independently between 403 referred and 64 inpatient infants who were treated for severe ROP.The mean GA of the infants with severe ROP was 31.2±2.7 weeks, mean BW was 1543.4±508.3 g. The risk factor analysis of inpatient infants revealed BW1500 g, GA32 weeks; intraventricular haemorrhage, respiratory distress syndrome, sepsis, apnoea and phototherapy were associated with a higher incidence of ROP. In addition, sepsis, male gender, multiple gestations, BW1500 g were associated with a higher incidence of progression to severe ROP, whereas maternal pre-eclampsia was associated with a lower incidence. On the other hand, comparison of demographic features revealed that the referred infants with ROP were born at a significantly higher BW and needed significantly earlier treatment than inpatient infants with ROP.The high BW and GA of infants with severe ROP indicate wider screening criteria should be used in our country. BW might be a more important criterion than GA for ROP screening.

A male infant was born to a 24-year-old mother (gravida 1 para 1) by cesarean delivery at 33 1/7 weeks of gestation. The physical examination revealed a large mass protruding from the baby's mouth, which appeared to be attached to the palate. Tracheostomy was performed immediately in the delivery room. A partial surgical excision was performed on the second postnatal day, removing most of the teratoma (epignathus), which was attached to the back of the pharynx and protruding from the baby's mouth measuring 13 × 11 × 9 cm and weighing 545 g. The final pathological diagnosis was “malignant epignathus with nephroblastoma component.” According to our knowledge, this is the first case that have malignant epignathus including nephroblastoma component in the literature.

A prenatally diagnosed patient was referred to our hospital at 35 weeks of gestation. Antenatal ultrasonography demonstrated cardiomegaly and aneurysm of the vein of Galen. A 3,290 g male baby was delivered by elective cesarean section at 37 weeks of gestation. Physical examination was remarkable for tachypnea, hyperdynamic precordium with a continuous murmur, cranial bruit and bounding carotid pulses. Magnetic resonance angiography confirmed vein of Galen aneurysmal malformation and demonstrated the vessels feeding the aneurysm. Postnatal management included aggressive medical treatment of cardiac failure and transarterial embolization of the vessels feeding the aneurysm at 3 days of age. Posthemorrhagic hydrocephalus developed after embolization, and a ventriculo-peritoneal shunt was placed at 29 days of age. Presently, the patient is 4 years of age and has no neurological abnormality at follow-up. Vein of Galen aneurysmal malformations can cause severe morbidity and mortality in neonates. However, careful obstetric follow-up and early postnatal endovascular treatment of these malformations may lead to a favorable outcome.

We report a newborn infant with psoas abscess caused by methicillin-sensitive Staphylococcus aureus. He was referred to our hospital with a history of hospital admission for hip septic arthritis without clinical improvement, and presented limited left hip motion, swelling on the groin and pain. A magnetic resonance imaging study revealed an abscess of the left psoas muscle. Surgical drainage and antibiotic treatment resulted in full recovery.
