Compared with term infants, late preterm infants are immature physiologically and metabolically, and have higher risks for medical complications such as respiratory distress, hypoglycemia, hyperbilirubinemia, sepsis, feeding difficulty and poor neurodevelopmental outcomes. The incidence of late preterm birth is increasing. We evaluated the clinical and demographic characteristics, short-term outcomes and clinical courses of late preterm infants admitted to our neonatal intensive care unit (NICU). Data from NICU admissions of 605 late preterm and 1477 term infants in the 1-year period between June 2010 and May 2011 were analyzed. There were 2004 late preterm deliveries and 18,854 total deliveries. Of late preterm infants, 30% were admitted to the NICU. The mean gestational age and birth weight were 35 1/7 weeks and 2352g, respectively. The admission diagnoses were respiratory distress (46.5%), low birth weight (17.5%), jaundice (13.7%), feeding difficulty (13.1%), polycythemia (8.1%) and hypoglycemia (4%); these morbidity rates were higher than those in term infants (p < 0.001). The overall mean hospitalization period was 7.5±9.1 days. The respective mortality and rehospitalization rates were 2.1% and 4.4%, which were higher than those for term infants (p < 0.001). In conclusion, late preterm infants should be followed closely for the complications just after birth, and preventive strategies should be developed. © 2013 Informa UK, Ltd.

Objective: To investigate the role of interleukin-6 (IL-6) and C-reactive protein (CRP) in non-thyroidal illness (NTI) in premature infants. Methods: Serum levels of IL-6 and CRP, thyroid-stimulating hormone (TSH), total thyroxine (T4), free T4 (fT4), total triiodothyronine (T3), and free T3 (fT3) were determined at the 1 st, 2 nd and 4th weeks of postnatal life in 148 premature infants born before 33 weeks of gestation. Results: At the 1 st week, serum T3 was negatively correlated with IL-6 (r= -0.33, p= 0.001) and CRP (r= -0.17, p= 0.03). Serum T3 was negatively and more strongly correlated with IL-6 (r= -0.49, p= 0.001) and CRP (r=- 0.33, p= 0.03) at the 2 nd week, at which time sepsis frequency and low T3 rates were the highest. At the 4 th week, mortality rate was higher among infants with lower T3 levels. Conclusions: High IL-6 and CRP values related to neonatal sepsis might have a significant role in the pathogenesis of NTI in premature infants. ©Journal of Clinical Research in Pediatric Endocrinology, Published byGalenos Publishing.

Objective: To compare oral ibuprofen with intravenous ibuprofen for closure of patent ductus arteriosus in very low birth weight (VLBW) preterm infants. Study design: In a prospective, randomized study, 102 VLBW preterm infants with patent ductus arteriosus received either intravenous or oral ibuprofen at an initial dose of 10 mg/kg, followed by 5 mg/kg at 24 and 48 hours. The success rate and evaluation of renal tolerance using cystatin-C were the major outcomes. Results: Patent ductus arteriosus closure rate was significantly higher with oral ibuprofen (84.6% versus 62%) after the first course of the treatment (P = .011). The cystatin-C level increased significantly after treatment in the oral group (P = .001), but did not change with intravenous ibuprofen (P = .4). Conclusions: Oral ibuprofen is more effective than intravenous ibuprofen for ductal closure in VLBW infants. The increase in the cystatin-C level with oral treatment suggests that patients with borderline renal function should be evaluated and followed closely. Copyright © 2011 Mosby Inc.

BACKGROUND: The primary aim of this randomized study was to describe the feasibility of early administration of surfactant via a thin catheter during spontaneous breathing (Take Care) and compare early mechanical ventilation (MV) requirement with the InSurE (Intubate, Surfactant, Extubate) procedure. METHODS: Preterm infants, who were ,32 weeks and stabilized with nasal continuous positive airway pressure (nCPAP) in the delivery room, were randomized to receive early surfactant treatment either by the Take Care or InSurE technique. Tracheal instillation of 100 mg/kg poractant a via 5-F catheter during spontaneous breathing under nCPAP was performed in the intervention group. In the InSurE procedure, infants were intubated, received positive pressure ventilation for 30 seconds after surfactant instillation, and placed on nCPAP immediately. RESULTS: One hundred infants in each group were analyzed. The MV requirement in the first 72 hours of life was significantly lower in the Take Care group when compared with the InSurE group (30% vs 45%, P = .02, odds ratio -0.52, 95% confidence interval -0.94 to -0.29). Mean duration of both nCPAP and MV were significantly shorter in the Take Care group (P values .006 and .002, respectively). Bronchopulmonary dysplasia rate was significantly lower among the infants treated with the Take Care technique (relative risk -0.27, 95% confidence interval -0.1 to -0.72) CONCLUSIONS: The Take Care technique is feasible for the treatment of respiratory distress syndrome in infants with very low birth weight. It significantly reduces both the need and duration of MV, and thus the bronchopulmonary dysplasia rate in preterm infants. Copyright © 2013 by the American Academy of Pediatrics.

Background Recently several developed countries have improved the safety and efficacy of drugs used in infants and pediatric patients. Most drugs administered to adults have licensed approvals outlining indications, doses, and the recommended route of administration. However, many drugs that are given to children are unlicensed or used off-label. Objectives To assess the extent and nature of unregistered and off-label drug use in neonatal intensive care units (NICUs) in Turkey, and to explore awareness and views of the general public on the unlicensed use of medicine in preterm and term infants in developing countries. Study Design A prospective observational study of a dynamic cohort of 464 neonates from 17 NICUs in Turkey. All medications administered to neonates who were hospitalized and admitted to the NICU over a 24-h period were recorded. The prescriptions were analyzed to determine whether the medicines were used in a licensed or unlicensed manner. Results In total, 1,315 prescriptions comprising 93 different medicines were written. We found that 62.3% of the drugs prescribed to the neonates over the 24-h period were unlicensed or off-labeled. Conclusions The present study indicates that unlicensed and off-label medicines are frequently used in preterm and term infants in Turkish NICUs. This finding is consistent and reported in other countries. We believe that the needs of the neonatal population must be a priority and access to safe and appropriate medicines requires urgent attention. © 2011 CARS.

Objective To compare the efficacy and safety of oral paracetamol and oral ibuprofen for the pharmacological closure of patent ductus arteriosus (PDA) in preterm infants. Study design This prospective, randomized, controlled study enrolled 90 preterm infants with gestational age ≤30 weeks, birthweight ≤1250 g, and postnatal age 48 to 96 hours who had echocardiographically confirmed significant PDA. Each enrolled patient received either oral paracetamol (15 mg/kg every 6 hours for 3 days) or oral ibuprofen (initial dose of 10 mg/kg, followed by 5 mg/kg at 24 and 48 hours). Results Spontaneous closure rate for the entire study group was 54%. After the first course of treatment, the PDA closed in 31 (77.5%) of the patients assigned to the oral ibuprofen group vs 29 (72.5%) of those enrolled in the oral paracetamol group (P =.6). The reopening rate was higher in the paracetamol group than in the ibuprofen group, but the reopening rates were not statistically different (24.1% [7 of 29] vs 16.1% [5 of 31]; P =.43). The cumulative closure rates after the second course of drugs were high in both groups. Only 2 patient (2.5%) in the paracetamol group and 3 patients (5%) in the ibuprofen group required surgical ligation. Conclusion This randomized, controlled clinical study compared oral paracetamol with ibuprofen in preterm infants and demonstrated that paracetamol may be a medical alternative in the management of PDA. © 2014 Mosby Inc.

Patent ductus arteriosus (PDA) is the most common cardiac condition in preterm infants. The most commonly used drugs for this purpose are cyclooxygenase inhibitors, mainly indomethacin and ibuprofen, which block the conversion of arachidonic acid to prostaglandins. On the other hand, several adverse effects have been reported with such medications, including peripheral vasoconstriction, gastrointestinal bleeding and perforation, weakened platelet aggregation, hyperbilirubinemia and renal failure. The role of oral paracetamol as an alternative treatment for the closure of PDA has gained importance in recent years. In this review, we aimed to determine safety of therapeutic drugs used in management of PDA in preterm infants rather than their efficacy in ductal closure. Two worldwide commonly used therapeutics (indomethacin and ibuprofen) and a new alternative medication as paracetamol are discussed. Ibuprofen seems to be the first choice due to its higher safety profile, as it is associated with fewer gastrointestinal and renal side effects than indomethacin. Recent studies suggest that paracetamol may be a medical alternative in the management of PDA with low adverse events and side effects. © 2015 Bentham Science Publishers.

Objective: To draw attention to the left ventricular false tendon which can be misinterpreted as echogenic focus in the fetus. Methods: The study group consisted of 9 fetuses out of the 161 who had been misdiagnosed for left ventricular false tendon as echogenic focus by obstetricians. Fetal echocardiography and 2-D color Doppler echocardiography were performed in the pre-postnatal period. The standard fetal echocardiographic views (4,5 chamber views, long axis view of the left ventricle, short axis view of the ventricles and great arteries, three vessels and trachea view, long axis views of the duct and aortic arch) were obtained for each case. Results: Of the 161 fetuses with echogenic focus in the left ventricle which underwent fetal echocardiography, 9 (5.6%) were diagnosed with false tendons present in the left ventricular cavity with no other cardiovascular anomaly. Six out of 9 patients underwent amniocentesis as follows: for age of over 35. years (two patients), abnormal double-triple screening tests plus echogenic focus (two patients) and soft ultrasonographic markers including echogenic focus (two patients). These fetuses revealed no cardiovascular and other systemic pathology or dysmorphism except for false tendons in the left ventricular cavity. Conclusion: False tendon should be taken into account as differential diagnosis of left ventricular echogenic focus in the fetus. Misinterpretation of false tendon as echogenic focus may cause unnecessary fetal invasive approach and maternal anxiety, especially when it arises with a background of borderline fetal findings and knowledge. © 2013 Elsevier Ltd.


Nosocomial sepsis agents with multidrug resistance have led to higher morbidity and mortality in premature infants in the recent years. Acinetobacter baumannii has become a leading cause of nosocomial sepsis in several neonatal intensive care units. In this study, the demographic, clinic, microbiologic characteristics and risk factors of 21 premature infants hospitalized in newborn intensive care unit between January 2010-February 2011 and developed A.baumannii infection, have been evaluated retrospectively. The isolates were identified by conventional methods and antibiotic susceptibility tests were performed by Vitek 2 GN and AST-N090 using Vitek 2 Compact system (BioMerieux, France). A.baumannii was isolated from the blood samples of 10 patients, central venous catheter samples of three patients, CSF samples of two, tracheal aspirate of two and urine sample of one patient. In two patients both blood and central venous catheter samples and in one patient both blood and CSF samples revealed A.baumannii. Gestational age was between 22-30 weeks and birth weight was between 500-1320 grams (17 were < 1000 g) in 19 patients. A.baumannii caused early onset (≤ 3 days) sepsis in four, and late onset (≥ 4 days) sepsis in 17 patients. The main risk factors were detected as mechanical ventilation (n= 20, 95%), prematurity (n= 19, 91%), total parenteral nutrition (n= 17, 81%) and central catheter use (n= 14, 67%). Antibiotics with highest rates of susceptibility were gentamicin (18/21), amikacin (14/21), and colistin (10/21). Twenty (95%) isolates had multiple drug resistance. Amikacin, gentamicin, colistin and imipenem were used for treatment, however 12 infants, 8 of which due to sepsis, died. In conclusion, A.baumannii which is an important nosocomial sepsis agent with multidrug resistance, is increasing in incidence. To control Acinetobacter infections especially in low-birth weight infants, the use of invasive procedures, total parenteral nutrition and broad spectrum antibiotics should be limited and infected patients should be isolated besides establishment of other appropriate infection control measures.

Evidence that oxidative stress plays a role in the development of bronchopulmonary dysplasia (BPD). There is a close relationship between oxidative stress and inflammation. In this study, it is aimed to investigate influences of hydrocortisone used in the treatment of BPD on anti-oxidant system in preterm infants with BPD. The study enrolled 33 infants with severe BPD who were undergone inpatient treatment in neonatal intensive care unit (NICU) of our Hospital and received therapy with hydrocortisone. Total oxidant status (TOS) and total anti-oxidant capacity (TAC) levels of infants enrolled to the study before and one week after the hydrocortisone therapy were studies and oxidative stress index levels were calculated. Pre- and post-treatment TOS, TAC and OSI index levels were statistically compared. In preterm infants with BPD, who were enrolled into the study, TOS and OSI index were found high, whereas TAC values were low. Following the treatment with hydrocortisone, statistically significant decrease in TOS and OSI index and statistically significant elevation in TAC levels were found in comparison with pre-treatment levels. The treatment with hydrocortisone, which is used for BPD, improves anti-oxidant system and reduces oxidative stress in infants with BPD. There is need for further studies in order to clarify the physio-pathogenesis.
