Use of Colistin in a Neonatal Intensive Care Unit: A Cohort Study of 65 Patients.

BACKGROUND The emergence of infections related to multidrug-resistant Gram-negative bacilli (MDR-GNB) reintroduced the use of colistin, an antibiotic that was previously abandoned due to adverse effects. However, because of its limited use in neonatal intensive care units, there is very little data about the effectiveness and safety of colistin in children and newborns. In this study, which will be the largest case study in the literature, we aimed to evaluate the effectiveness and safety of colistin in full-term and preterm newborns. MATERIAL AND METHODS The study included patients admitted into 2 level 3 neonatal intensive care units between January 2013 and June 2015. The medical records of patients diagnosed with sepsis, meningitis, pneumonia, and urinary tract infection based on the diagnostic culture results and treated with colistin were analyzed retrospectively. The patients whose infections were not verified were excluded from the study. RESULTS The study included 65 patients (18 term, 47 preterm). The most frequently isolated pathogens were Klebsiella pneumoniae and Acinetobacter baumannii followed by Pseudomonas aeruginosa and Enterobacter cloacae. Mean colistin treatment time was 15±3.5 days. All patients treated with colistin were being treated with at least 1 other antibiotic. While a complete clinical response was achieved in 51 (72.3%) patients, 14 (21.5%) patients died during treatment. Four (7.7%) patients died during as a result of another infection. Three patients developed renal toxicity, another 3 patients had seizures, and apnea was observed in 3 patients. CONCLUSIONS Colistin was found to be effective and safe for treatment of MDR-GNB infections in preterms and infants with very low birth weight. Given the severity of the infection, the adverse effects of colistin were at acceptable levels.

Factors Affecting the Target Oxygen Saturation in the First Minutes of Life in Preterm Infants.

Background: The aim of this study was to describe the effect of factors on time to reach a pulse oxygen saturation (SpO2) level of 90% in preterm infants in the delivery room. Methods: Preterm (<35 gestational age) infants who did not require supplemental oxygen were included in the study. Continuous recordings were taken by pulse oximetry during the first 15 min of life. Results: Of 151 preterm infants, 79 (52.3%) were female and 126 (83.5%) were delivered by cesarean section. Target saturation level (≥90%) was achieved faster in preductal measurements. Mean times taken to have a preductal and postductal SpO2 level of 90% were significantly lower in preterm babies born by vaginal delivery, with umbilical arterial pH ≥ 7.20 and whose mothers were non-smokers during pregnancy. Conclusions: Differences in achievement of target saturation level were influenced by multiple factors (birth way, probe location, maternal smoking and umbilical blood gas pH) in the delivery room during resuscitation of preterm babies.

Neonatal infection with Neisseria meningitidis: analysis of a 97-year period plus case study.

Neisseria meningitidis is one of the major causes of meningitis in children and adolescents, but it is rarely found during the neonatal period. Here, we describe a neonate with meningococcal sepsis who was admitted to the hospital on postnatal day 10, and we discuss the clinical features of neonatal infection with N. meningitidis in relation to the literature (analysis of a 97-year period).

A comparison of the effects of invasive mechanic ventilation/surfactant therapy and non-invasive nasal-continuous positive airway pressure in preterm newborns.

AIMS: This study compared the early-term outcomes of mechanical ventilation (MV)/surfactant treatment with nasal-continuous positive airway pressure (nCPAP) in preterm infants with respiratory distress syndrome (RDS). MATERIALS AND METHODS: Data from newborns born between ≥24 and ≤32 weeks of gestation, hospitalized at our newborn intensive care unit, and diagnosed with RDS between January 2009 and February 2012 were analyzed. RESULTS: Of 193 newborns with RDS who were enrolled in the study, 113 were treated with nCPAP and 80 with MV at a level of 57.5% of nCPAP. Within the study group, 46.3% of the infants were female. The mean gestation of the continuous positive airway pressure (CPAP) group was 29.07 ± 1.99 weeks; that of the MV group was 28.61 ± 2.01 weeks. The birth weight was 1321.1 ± 325.4 g and 1240.3 ± 366.1 g; however, the difference between the two groups was not significant. MV was not required in 54.9% of the patients with nCPAP treatment. Bronchopulmonary dysplasia (BPD) developed in 20 (18.7%) patients in the nCPAP group and 18 (24.4%) patients in the MV group; the difference was not significant (p = .351). Between 2009 and 2012, nCPAP was used at a rate of 33.9, 70.8, 68.4, and 69%. The risk factors for developing BPD were low gestation week, duration of intubation, and proven sepsis (p = .0001, p = .004, and p = .011, respectively). CONCLUSIONS: Early nCPAP treatment in preterm infants (≤32 weeks of gestation) decreases both the need for MV and the use of surfactant, but without a significant effect on BPD development.

How should we give vitamin D supplementation? evaluation of the pediatricians' knowledge in Turkey.

BACKGROUND: We aimed to determine the knowledge and attitudes of Turkish pediatricians concerning vitamin D supplement. METHODS: The study was planned cross-sectional to be carried out between April-May 2015 in Turkey. A questionnaire form that determined the participants' opinions and practices concerning vitamin D supplement was completed via face-to-face interview. RESULTS: A total of 107 pediatricians (49.3%) and 110 pediatric residents (50.7%) participated in the study. Of the physicians, 85.2% recommended vitamin D supplement for all infants and children regardless of diet, 13.4% recommended for the infants which are solely breastfed. Vitamin D supplement is recommended at a dose of 400 IU/day by 88.8% of pediatricians and by 90% of pediatric residents. Of the pediatricians and pediatric residents, 72% and 68.2%, respectively commence vitamin D supplement when the newborn is 15 days old. The rates of recommending vitamin D supplement until the age of one and two years were higher among pediatricians (48.6% and 41.1%, respectively) than pediatric residents (40.9% and 32.7%, respectively). The rate of starting vitamin D supplement for fontanelle closure was significantly higher among pediatric residents (15.5%) than pediatricians (3.7%) (p = 0.002). It was determined that the rate of prescribing vitamin D supplement until fontanelle closure was higher among pediatric residents (18.2%) than pediatricians (0.9%). CONCLUSIONS: The present study suggest that the knowledge of pediatricians about recommendation of vitamin D needs to be enhanced by education programs in addition to free vitamin D supplement provided by the Ministry of Health.
