(2015) Hanta, Deniz; Torer, Birgin; Temiz, Fatih; Kilicdag, Hasan; Gokce, Mahmut; Erdogan, Ozlem; 26613228; JMQ-5983-2023
Neonatal central diabetes insipidus (DI) is an extremely rare disorder that can cause severe morbidity and mortality. We have reported a very low birth weight infant with idiopathic central DI presenting in the first month of life who was successfully treated with sublingual desmopressin therapy. In this report, we emphasize that central DI should be kept in mind in an infant with unexplained hypernatremia and polyuria. Timely diagnosis and treatment with lyophilized desmopressin may prevent severe morbidity and mortality.
Impact of antenatal corticosteroid exposure on thymus size in premature infants
(2022) Kilicdag, Hasan; Torer, Birgin; Demir, Senay; Hanta, Deniz; Akbas, Tugana; Mert, Mustafa Kurthan; Soker, Gokhan; 0000-0002-5505-8707; 34763993
Background: This study examined the effect of corticosteroids on the thymic index (TI) and the thymus/weight index (TWI) in infants exposed to antenatal corticosteroids (ACS). Methods: This prospective study was conducted between August 2014 and October 2018. A thymus ultrasound was performed to assess thymus size on the second day of life. Thymus size was assessed as TI and TWI. Results: In total, 167 neonates (<= 34 weeks gestation) constituted the study population, including 94 ACSexposed infants and 73 untreated infants. The treatment group exhibited significantly lower birth weight and significantly shorter birth length than the ACS (-) group. Therefore, TI was smaller in the treatment group than in the untreated group (6.96 +/- 4.05 cm(3) vs. 5.64 +/- 3.39 cm(3)). The TWI was 3.69 +/- 1.8 cm(3)/kg in the ACS (-) group versus 3.32 +/- 1.56 cm(3)/kg in the ACS (+) group. The median anteroposterior diameter of the right lobe was 1.33 cm (range, 0.45-2.40) in the ACS (-) group compared to 1.15 cm (range, 0.47-2.40) in the ACS (+) group. The median anteroposterior diameter of the left lobe was 1.40 cm (range, 0.43-2.20) in the ACS (-) group and 1.19 cm (range, 0.32-2.36) in the ACS (+) group. The median largest sagittal area was 2.64 cm(2) (range, 0.5-5.46) in the ACS (-) group versus 2.20 cm(2) (range, 0.55-5.90) in the ACS (+) group. Conclusion: We found that TWI was not significantly changed by ACS exposure in premature infants. (C) 2021 French Society of Pediatrics. Published by Elsevier Masson SAS. All rights reserved.
Is it Accurate to Separate Glucose-6-Phosphate Dehydrogenase Activity in Neonatal Hyperbilirubinemia as Deficient and Normal?
(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.
Is Umbilical Cord Milking Always an Advantage?
(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.
Primary Repair of Esophageal Atresia with Distal Tracheoesophageal Fistula in a Low-Birth-Weight Neonate
(2015) Hanta, Deniz; Metin, Seval; Cekinmez, Eren Kale; Torer, Birgin; Kilicdag, Hasan; Cevirgenoglu, Bahar
Esophageal atresia is complex congenital anomaly of respiratory tract occuring often associated with anomalies of other systems and chromosomal abnormalities. This congenital anomaly is a surgical emergency. The management mode of Esophageal atresia/Tracheoesophageal Fistula in the premature, low birth weight neonate remains controversial. Traditionally, treatment has been based on a staged approach. The primary repair of Esophageal atresia and fistula closure is achievable in Low Birth Weight infants and offer a good treatment in the absence of additional severe malformations. Treatment of these neonates should not be limited to tertiary pediatric surgical centers, contrarily it is also achievable in secondary heath care centers. Near cooperation with neonatal intensivist and the pediatric surgeon is essential for good survival.
