(2014) Kilicdag, Hasan; Gokmen, Zeynel; Ozkiraz, Servet; Gulcan, Hande; Tarcan, Aylin
Background: The aim of this study was to investigate glucose 6-phosphate dehydrogenase (G6PD) activity in term and late preterm babies with severe neonatal hyperbilirubinemia and its relationship to the severity and treatment of this disorder, regardless of level of G6PD activity (deficient/normal). Methods: A total of 529 term and late preterm (>= 35 weeks) infants (228 female, 301 male) who were diagnosed with severe hyperbilirubinemia were included in this study. In each case, serum was collected to evaluate blood group, direct Coombs' test, complete blood cell count, total and direct bilirubin, thyroid-stimulating hormone, and G6PD activity. A partial correlation analysis was carried out to assess the relationship between G6PD activity and total bilirubin levels. Results: A significant correlation was found between the severity of hyperbilirubinemia and G6PD activity in both males and females. Male neonates who had G6PD levels <12 U/g Hb required more phototherapy time than neonates who had G6PD levels >12 U/g Hb; and female neonates who had G6PD levels <16 U/g Hb required more phototherapy time than neonates who had G6PD levels >= 16 U/g Hb (p < 0.0001). When we analyzed only breastfed infants, a significant difference also emerged in both sexes. Decreased G6PD activity was associated with increased phototherapy time and the need for exchange transfusion. Conclusion: Routine checks of G6PD level in hyperbilirubinemic neonates are very important in providing proper medical management to prevent bilirubin-induced neurological dysfunction.

(2021) Tekin, Mehmet; Silahlı, Musa; Gokmen, Zeynel; 0000-0003-0944-7178; 0000-0002-8865-7044; 34816698; AAB-5059-2022
Background: Late preterm infants (LPIs) have increased steadily in all newborns delivery and they are the largest patient group requiring admission to the neonatal intensive care unit. Surfactant treatment is frequently used in LPIs in case of respiratory distress, but the procedure and the timing of surfactant administration are not well-known. Objective: We aimed to evaluate the effect of surfactant administration techniques on pulmonary outcomes in LPIs with respiratory distress. Methods: In this retrospective study, we compared the effects of the less invasive surfactant administration (LISA) technique and conventional treatment on respiratory and other morbidities in LPIs who have respiratory difficulties. We named these two groups as the LISA group and the conventional group (CG). Comparison of the mechanical ventilation (MV) rates between the groups was the primary outcome of our study. Results: There were 25 LPIs in each group. The duration of nasal continuous positive airway pressure (CPAP) and oxygenation were similar in both groups. The rate of MV and the duration of MV (P= 0.004 and P = 0.02) were lower in the LISA group. Also, the need for more than 1 dose of surfactant was higher in the MV requiring group, although it was not statistically significant between the groups (P= 0.21). Conclusion: Using the LISA technique for surfactant instillation reduces any MV requirement. LISA is a very useful and reliable technique in experienced hands in LPIs as in very preterm infants.

(2016) Kilicdag, Hasan; Gulcan, Hande; Hanta, Deniz; Torer, Birgin; Gokmen, Zeynel; Ozdemir, Sonay Incesoy; Antmen, Bulent Ali; 25731653
Objective: The role of cord milking as an alternative to delayed cord clamping is an area that requires more research. Purpose of this clinical trial was to investigate the impact of umbilical cord milking on the absolute neutrophil counts (ANCs) and the neutropenia frequency of preterm infants.Methods: Fifty-eight pregnant women were randomly assigned to one of the umbilical cord milking and control groups. A total of 54 preterm infants (gestational age 32 weeks) were enrolled into the study. The umbilical cords of 25 infants were clamped immediately after birth, and in 29 infants, umbilical cord milking was performed first.Results: The ANCs were statistically significantly lower in the cord milking group compared with the control group on days 1, 3 and 7. The frequency of neutropenia was higher in the cord milking group compared with the control group.Conclusion: In our study, ANCs were lower in the cord milking group and the frequency of neutropenia was higher. Umbilical cord milking plays a role on the ANCs of preterm infants.

(2019) Silahlı, Musa; Gokmen, Zeynel; Gokdemir, Mahmut; 0000-0003-0944-7178
Ectopiacordis is a rare anomaly. It is described that hearth is placed as partially or totally outside of thoracic cavity. Sometimes this can be accompanied liver and other organs such as intestine. Congenital heart defects are also likely to accompany to this situation. So, we present an ectopiacordis with double outlet right ventricule case who has lived for 121 days in neonatal intensive care unit.

Objectives: To compare the effect of umbilical cord milking and early cord clamping on thymic size, and neonatal mortality and morbidity in preterm infants. Methods: This single-center, prospective, double-blind, randomised controlled study was conducted at Baskent University, Konya Education and Research Centre, Konya, Turkey, between October 2015 and April 2016. Pregnant women who delivered before 32 weeks of gestation were randomised to receive umbilical cord milking (group 1) or early cord clamping (group 2). Ultrasonographic evaluation was performed in each newborn by an experienced radiologist within the first 24 hours of life. Thymic size was estimated in line with literature. SPSS 15 was used for all data analyses. Results: There were 38 subjects in group 1 and 37 in group 2. There were as many infants in the two groups (p>0.05) The haemoglobin levels was higher in group 1, but not significantly (p=0.213). The absolute neutrophil count in group 1 was significantly lower (p=0.017) than group 2. In terms of neonatal mortaility and morbidity, there were no significant differences between the groups (p>0.05). Conclusion: Umbilical cord milking was not associated with thymic size during the the first 24h of life.

(2016) Silahli, Musa; Gokdemir, Mahmut; Duman, Enes; Gokmen, Zeynel; 0000-0003-0944-7178; 0000-0002-2746-0547; 0000-0002-5676-2747; 27555161; AAB-5059-2022; AAX-9343-2021; AAJ-8069-2021; N-4174-2014
We present a catheter related severe hypernatremia in a 2-month-old baby who was admitted to the pediatric intensive care. Imbalance of plasma sodium is commonly seen in pediatric intensive care patients. The water and sodium balance is a complex process. Especially, brain and kidneys are the most important organs that affect the water and sodium balance. Other mechanisms of the cellular structure include osmoreceptors, Na-K ATPase systems, and vasopressin. Hypernatremia is usually an iatrogenic condition in hospitalized patients due to mismanagement of water electrolyte imbalance. Central venous catheterization is frequently used in pediatric intensive care patients. Complications of central venous catheter placement still continue despite the usage of ultrasound guidance. Malposition of central venous catheter in the brain veins should be kept in mind as a rare cause of iatrogenic hypernatremia. (C) 2016 Elsevier Inc. All rights reserved.

(2019) Karaca, Omer; Pinar, Huseyin Ulas; Gokmen, Zeynel; Dogan, Rafi; 0000-0003-0473-6763; 0000-0003-1933-2075; 30602192; Q-2420-2015; AAU-6923-2020
Background Injection to the accurate area without any complications is the main factor for the efficiencies of caudal block. The aim of this study was to compare success and the complications of conventional and ultrasound method for caudal block in children. Materials and Methods Two-hundred sixty-six American Society of Anesthesiologists (ASA) category 1 children aged between 6 months and 6 years undergoing hypospadias, circumcision, or both surgeries were randomly allocated two groups (Group C or Group H, n =133). About 0.25% bupivacaine with 1/200000 adrenaline (total volume: 0.5 mL/kg) was injected after the needle was inserted into the sacral canal in Group C, or right after the needle pierced the sacrococcygeal ligament under longitudinal ultrasound view in Group H. Success rate of block, block performing time, number of needle puncture, success at first puncture, complication rate, age and weight of the patients encountering these complications were recorded. Results The success rate of block was similar between two groups (94.7% in Group C vs 96.2% in Group U, p >0.05). Success at first puncture was higher in Group U than in Group C (90.2 vs 66.2%, respectively; p <0.001). Number of needle puncture, blood aspiration, subcutaneous bulging, and bone contact was higher in Group C but none in Group U ( p <0.001) and these complications were occurred in children weighing<16kg and less younger than 6 years old. Conclusion We observed that the complications were not encountered, number of needle puncture was lesser, and the success rate of first puncture was higher under ultrasound with longitudinal view.
