Early neonatal outcomes of very-low-birth-weight infants in Turkey: A prospective multicenter study of the Turkish Neonatal Society.

OBJECTIVE: To investigate the early neonatal outcomes of very-low-birth-weight (VLBW) infants discharged home from neonatal intensive care units (NICUs) in Turkey. MATERIAL AND METHODS: A prospective cohort study was performed between April 1, 2016 and April 30, 2017. The study included VLBW infants admitted to level III NICUs. Perinatal and neonatal data of all infants born with a birth weight of ≤1500 g were collected for infants who survived. RESULTS: Data from 69 NICUs were obtained. The mean birth weight and gestational age were 1137±245 g and 29±2.4 weeks, respectively. During the study period, 78% of VLBW infants survived to discharge and 48% of survived infants had no major neonatal morbidity. VLBW infants who survived were evaluated in terms of major morbidities: bronchopulmonary dysplasia was detected in 23.7% of infants, necrotizing enterocolitis in 9.1%, blood culture proven late-onset sepsis (LOS) in 21.1%, blood culture negative LOS in 21.3%, severe intraventricular hemorrhage in 5.4% and severe retinopathy of prematurity in 11.1%. Hemodynamically significant patent ductus arteriosus was diagnosed in 24.8% of infants. Antenatal steroids were administered to 42.9% of mothers. CONCLUSION: The present investigation is the first multicenter study to include epidemiological information on VLBW infants in Turkey. Morbidity rate in VLBW infants is a serious concern and higher than those in developed countries. Implementation of oxygen therapy with appropriate monitoring, better antenatal and neonatal care and control of sepsis may reduce the prevalence of neonatal morbidities. Therefore, monitoring standards of neonatal care and implementing quality improvement projects across the country are essential for improving neonatal outcomes in Turkish NICUs.

Effects of the storage of breast milk at different temperatures on total antioxidant capacity, total oxidant status, and paraoxonase-1 level.

Konak M, Minici M, Tarakçi N, Altunhan H, Toker A, Örs R. Effects of the storage of breast milk at different temperatures on total antioxidant capacity, total oxidant status, and paraoxonase-1 level. Turk J Pediatr 2019; 61: 1-6. Breast milk is a well-balanced ideal nutritional source with high bioavailability for infants. As being a fresh, biological and dynamic product, changes in the breast milk during these storage periods have been the subject of ongoing research. This study aims to evaluate total antioxidant capacity (TAC), total oxidant status (TOS), and paraoxonase-1 (PON-1) levels of fresh and freezestored breast milk. Ten cc of breast milk was obtained from the mothers as the days between 10 and 15 in the morning within a 1-hour period. TAC, TOS, and PON-1 levels were evaluated in the fresh breast milk. Collected breast milk samples were divided into two groups for storage at -20°C or -80°C. Stored samples were tested for TAC, TOS, and PON-1 levels after 72 hours. The highest TAC level was detected in fresh breast milk (p < 0.05). The TOS levels of fresh breast milk showed a statistically significant reduction in rate after storage. The TOS levels at -20°C and -80°C were significantly lower at -80°C (p < 0.05). Our study results show that oxidant and antioxidant activities are at the maximum level in the fresh breast milk. In terms of antioxidant status the effect of freezing temperatures hasn`t been determined. We conclude that it is more convenient to store the breast milk at -80°C than to store at -20°C in terms of preserving the storage TOS level.

Mosaic trisomy 14 and aorta-pulmonary window association: A case report.

Trisomy 14 mosaicism is a rare chromosomal abnormality with distinct and recognizable clinical features. Congenital heart anomalies can accompany in this syndrome. To the best of our knowledge, this is the first case of mosaic trisomy 14 with an aortopulmonary window to be described in the literature.

Glanzmann Thrombasthenia in a Newborn with Heterozygous Factor V Leiden and Heterozygous MTHFR C677T Gene Mutations.

INTRODUCTION: Glanzmann thrombasthenia is a rare congenital platelet dysfunction. CASE CHARACTERISTICS: A 2-day-old male neonate delivered at 35 weeks' gestation was referred with extensive bruising and jaundice. His elder sibling had Glanzmann thrombasthenia, and his mother had thrombophilic risk factors. Flow cytometric analysis revealed absent CD41/CD61. A molecular thrombophilia panel revealed the presence of heterozygous factor V Leiden G1691A and methylenetetrahydrofolate reductase C677T gene mutations. OUTCOME: General precautions to avoid injuries and spontaneous bleeding were advised. MESSAGE: Life-threatening bleeding may not be the first finding in cases of thrombasthenia accompanied by thrombophilic risk factors.

A congenital cranial dysinnervation disorder: Möbius' syndrome.

Möbius' syndrome, also known as Möbius' sequence, is a nonprogressive cranial dysinnervation disorder characterized by congenital facial and abducens nerve paralysis. Here, we report a 5-day-old girl who was conceived after in vitro fertilization with poor suck and facial paralysis. She had bilaterally ptosis and lateral gaze limitation, left-sided deviation of the tongue, dysmorphic face, hypoplastic fingers and finger nails on the left hand, and was diagnosed as having Möbius' syndrome. Involvement of other cranial nerves such as three, four, five, nine, 9 and 12, and limb malformations may accompany this syndrome. However, several factors have been proposed for the etiology, some rare cases have also been reported with artificial reproductive technologies. Feeding difficulties and aspiration are the main problems encountered in infancy. The other cranial nerves should be examined further in newborns who present with congenital facial palsy, and other cranial dysinnervation disorders should be considered in the differential diagnosis.

Total antioxidant, total oxidant and serum paraoxonase levels according to lipid administration method in parenterally fed premature infants.

OBJECTIVE: The aim of our study was to determine whether lipid solutions delivered separately or in mixture with total parenteral nutrition (TPN) solutions effect the balance between oxidant and antioxidant levels in premature infants. METHODS: A total of 60 preterm newborns who were delivered at their 30-34 gestational weeks and received TPN were included in the study. Premature newborns were randomized into two groups based on the delivery method of the lipid solution, separately (Group 1) or in mixture with TPN solutions (Group 2). Total antioxidant status (TAS), total oxidant status (TOS) and paraoxonase (PON-1) levels were analyzed in both blood samples, and oxidative stress index (OSI) was also calculated. RESULTS: Thirty cases from both groups were included in the study. Statistically significant decrease in the level of TAS and increase in the level of PON-1 were detected at 72 h of TPN therapy in both groups (p < 0.05). Statistically significant decrease in both TOS and OSI levels were observed in Group 2 (p < 0.05). In association with these findings, any statistically significant intergroup difference was not detected in both parameters regarding oxidant balance (p > 0.05). CONCLUSION: Our study showed that according to lipid administration method any difference for oxidant-antioxidant balance was not detected.

Effects of Prednisolone, L-Asparaginase, Gemfibrozil, and Combinations of These Elements on Mice Lipid Profile, Liver, and Pancreas.

The aim of this study is to determine the effects of L-asparaginase (L-ASP), corticosteroids (CSs), and antilipidemics, separately and in combination, on the lipid profiles and the liver and pancreas histology in mice. This study included 8 groups of 7 mice each. Before any drug administration, serum samples were taken from all of the mice. Then, normal saline was applied to the control group, and a medication or combination of medications was applied to the other groups. Levels of triglycerides, cholesterol (COL), and high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were determined, and the livers and pancreases were evaluated histologically at the end of the study. Triglycerides increased significantly in the CS-only and the L-ASP-only groups, COL increased significantly in the CS-only group, and HDL increased significantly in the CS-only and the antilipidemic-only groups. LDL was significantly lower in the CS-only and the L-ASP-only groups. CSs and L-ASP were significantly effective in liver necrosis, L-ASP was significantly effective in liver balloon degeneration, and CS were significantly effective in pancreas vacuolization. Triglyceride measurement is recommended before/during CS and/or L-ASP treatment. Starting with an antilipidemic agent can be considered to avoid possible complications in patients with significantly high rates. Indicators of a possible liver or pancreas injury should also be considered.

Fully automated simultaneous umbilical arteriovenous exchange transfusion in term and late preterm infants with neonatal hyperbilirubinemia.

OBJECTIVES: The purpose of this study was to compare the efficacy and safety of two different catheterization techniques of exchange transfusion (ET) used in the therapy of newborn jaundice: fully automated two-way ET technique and the classical one-way ET. PATIENTS AND METHODS: The study included babies at gestational age of >34 weeks. In total, 107 ETs were performed on 86 babies. Totally, the umbilical vein (UV) group included 54 babies having undergone 69 ETs and the UV/UA group included 32 babies having undergone 38 ETs. RESULTS: The declines in bilirubin levels right after ET (p = 0.018) and 8 h after ET (p = 0.014) were higher in the fully automated UV/UA technique than in the classical UV technique. Furthermore, the duration of intensive phototherapy following ET was shorter in the UV/UA method than in the UV method (p = 0.003). There was no difference between the two methods in terms of ET-associated complications (p = 0.927). CONCLUSIONS: In neonatal hyperbilirubinemia, ET with fully automated UV/UA technique is more efficient than the classical ET technique, causing no additional side-effects. It is also more physiological than the classical technique, since it minimizes the fluctuations in the blood volume and intravascular pressure during ET.

Late-onset Streptococcus pasteurianus sepsis in a preterm baby in a neonatal intensive care unit.

Apnea, cyanosis, lethargy and prolongation in capillary filling time developed on the postnatal 37(th) day in a preterm baby who was born at the 30(th) gestational week with a birth weight of 1 300 g. Acute phase reactants and immature/total neutrophil count ratio were found to be high. The patient who was diagnosed with sepsis was successfully treated with meropenem which was started empirically. In his blood culture Streptococcus pasteurianus grew. S. pasteurianus is in the subgroup of streptococcus bovis which is one of the D group streptococci and its previous name is S. bovis type II/2. In the literature, there are very few cases of neonatal infection related with this bacterium. As far as we know, this is first case of neonatal sepsis caused by S. pasteurianus in Turkey. In addition, we tried to determine the clinical properties of neonatal infections arising from S. pasteurianus by reviewing the literature.
