RESUMEN
BACKGROUND: The prediction of adverse conditions in the preterm neonatal brain might be improved by cerebral monitoring using combined measures of cerebral function, including oxygenation and blood flow parameters. To perform the consecutive measurements of the resistive index (RI) from the anterior cerebral artery (ACA) within the first week of life and to evaluate the association of these measurements with cerebral oxygen saturation (Csat) detected by near-infrared spectroscopy (NIRS). METHODS: This prospective cohort study enrolled very preterm infants, <32 weeks of gestational age, admitted to a tertiary neonatal intensive care unit. Csat levels were continuously monitored using NIRS for 72 h after birth. ACA RI measurements were obtained on the first, third, and seventh days of life by using transcranial Doppler ultrasound. These measurements were also compared between infants with and without unfavorable outcomes, including severe intraventricular hemorrhage (IVH) and early mortality. RESULTS: A total of 96 preterm infants with Csat and ACA RI measurements were analyzed. Age at birth was 28.3 ± 1.9 weeks and birth weight was 1090 ± 305 g. The mean Csat of the infants was 77.1% ± 8.2% during the first 72 h of life. Mean ACA RI values were 0.76 ± 0.10, 0.75 ± 0.08, and 0.77 ± 0.08 on the first, third, and seventh days of life, respectively. RI on the first day of life was significantly higher in infants delivered by cesarian section than in those delivered vaginally (0.77 vs. 0.69; p = 0.017). Infants who died earlier had significantly higher ACA RI values on the first day than infants who survived beyond the first 7 postnatal days (0.83 vs. 0.76; p < 0.001). DISCUSSION: There was no association between ACA RI and Csat in the early period of life. ACA RI values on the first postnatal day might be significant for predicting early mortality in very preterm infants.

BACKGROUND: Recurrent angioedema is a rare entity during childhood. This study aimed to clarify differences between hereditary angioedema (HAE) and histaminergic angioedema (HA) in children. METHODS: Fifty-seven children with HAE (male 36.8%, 8.9 years [5.4-12.5]) and 42 children with recurrent HA (male 42.9%, 11.5 years [8.1-16.8]) were analyzed. RESULTS: The median age at symptom onset (6 [3-10]; 7.8 [4.5-13] years), frequency of angioedema episodes within last year (3 [2-5]; 5 [2-10]), and duration of symptoms (48 [24-48]; 24 [12-48] hours) were similar in the HAE and HA group, respectively. Recurrent urticaria was observed in 7.3% (n = 3) of patients in the HAE group and in 45.2% (n = 19) of the HA group (P < .001). While angioedema episodes involving the lips (n = 30; 71.4%; P = .035) and eyelids (n = 28; 66.7%; P = .012) were observed more frequently in the HA group, gastrointestinal involvement/abdominal pain (n = 15; 36.6%) was more common in HAE (P < .001). Itching as a prodromal symptom was detected in 47.6% (n = 20) of HA patients versus 14.6% (n = 6) of those with HAE (P = .002). In the logistic regression analysis for the diagnosis of HAE, a family history of angioedema (OR = 58.289 [95% CI 10.656-318.853], P < 001) and trauma (OR = 35.208 [95% CI [4.368-283.794]], P = .001) as a triggering factor were determined to be independent variables. CONCLUSION: A family history of angioedema, trauma as a triggering factor, and abdominal pain should suggest the diagnosis of HAE and the need for further investigation.

INTRODUCTION: Robust evidence revealed the impact of antenatal corticosteroid (ACS) administration on lower mortality and short-term neonatal outcomes in singleton preterm infants. We aimed to investigate the impact of ACS therapy on morbidity and mortality in preterm twin infants. METHODS: We conducted this retrospective single-center study from to the records of twin babies of 24-30 weeks of gestation admitted to the neonatal intensive care unit. The study population was grouped based on the exposure to ACS 1-7 days before birth as received or not. Groups were compared regarding in-hospital mortality and neonatal outcomes. RESULTS: Data from 160 twin infants were analyzed. Of those, 102 (64 %) were administered ACS. The median (IQR) gestational age and birth weight of the whole cohort were 28 (27-29) weeks and 1060 (900-1240) g, respectively. ACS administration was associated with a significant decline in respiratory distress syndrome (RDS), requirement ≥2 doses of surfactant, severe intraventricular hemorrhage (IVH), early-onset sepsis (EOS), and retinopathy of prematurity (ROP) requiring treatment (p < 0.05). Logistic regression analysis revealed that gestational age (OR 0.29 95 % CI 0.14-0.62; p = 0.001), ACS administration (OR 0.14 95 % CI 0.03-0.85; p = 0.032), and time to achieve full enteral feeding (OR 1.16 95 % CI 1.03-1.31; p = 0.019) were independently associated with the risk of severe ROP. CONCLUSION: The reduction in the risk of severe ROP besides RDS, severe IVH, and EOS among preterm twins who received ACS was remarkable in our study similar to the trials conducted in preterm singletons. However, large-scale prospective observational studies are required to reveal the efficacy of ACS in preterm twins.

BACKGROUND: Preterm infants are at risk of extrauterine growth restriction (EUGR) and associated complications in the long term. Growth curves are important in assessing postnatal growth in these infants. The aim of this study was to determine the prevalence of EUGR in preterm infants and the factors associated with EUGR using two different growth curves. METHODS: We retrospectively evaluated 596 preterm infants with birth weight ≤1500 g. Small for gestational age (SGA) was defined as birth weight <10th percentile for gestational age. EUGR was defined as discharge weight z score <-2. All z scores were determined using both the Fenton 2013 and Intergrowth-21st (IG-21) growth curves. RESULTS: The infants' median gestational age was 28 weeks (27-29) and median birth weight was 1080 g (900-1243). The prevalence of SGA was 9.2% with IG-21 curves and 5% with Fenton curves (p < 0.001). The median discharge weight was 2060 g (1860-2363). The prevalence of EUGR was significantly higher with the Fenton curves than with the IG-21 curves (38% vs. 31.7%, p < 0.001). The mean discharge weight z score was -1.82±1.29 with Fenton and -1.44±1.49 with IG-21 curves. In multivariate analysis, significant risk factors for EUGR according to the Fenton curves were SGA (odds ratio [OR]: 19.15, 95% confidence interval [CI]: 4.4-82.59), respiratory distress syndrome (RDS) (OR 1.64, 95% CI 1.12-2.4), late neonatal sepsis (LNS) (OR: 2.27, 95% CI: 1.5-3.44), and >16 days to full enteral feeding (OR: 1.8, 95% CI: 1.22-2.68). Similarly, independent risk factors for EUGR according to the IG-21 curve were SGA (OR: 16.3, 95% CI: 7.23-36.9), RDS (OR: 1.81, 95% CI: 1.16-2.83), LNS (OR: 2.29, 95% CI: 1.43-3.68), and >16 days to full enteral feeding (OR: 2.11, 95% CI: 1.38-3.23). CONCLUSION: The growth curves used for diagnosis may lead to differences in EUGR rates in intensive care units and the factors identified as associated with EUGR. At-risk infants should be evaluated for EUGR and their weight and nutritional support should be monitored carefully. Comparisons of long-term outcomes are needed to assess the suitability of growth curves used for EUGR follow-up.

BACKGROUND: Tracheal agenesis (TA) is a rare congenital defect that consists of a complete or partial absence of the trachea below the larynx, with or without tracheoesophageal fistula (TEF). It is a severe congenital defect with a very high mortality rate. The recommended surgical approach is esophageal ligation and gastrostomy. Despite the progress in reconstructive surgical techniques, the outcome of the anomaly is still very poor. We described a case of TA with a TEF in a female newborn with a hemivertebra, single ventricle, single atrioventricular valve, single atrium, and cardiac left isomerization. CASE: The patient, who was born at 37 weeks of age, was diagnosed with imaging methods, as the cyanosis did not improve despite being intubated many times in the delivery room; the cyanosis improved after esophageal intubation. Despite all life support treatment, the patient died on the fourth day of life. At autopsy, tracheal agenesis was diagnosed. CONCLUSIONS: In newborns who cannot be intubated in the delivery room or whose lungs cannot be ventilated despite being intubated and whose cyanosis cannot be corrected, tracheal agenesis should be considered and ventilation with esophageal intubation should also be tried.

BACKGROUND: Discrimination of the cases with severe and mild pneumonia is crucial due to the requirement of hospitalization, additional management, and treatment protocols. We aimed to analyze the role of IL6 (Interleukin), IL8, IL10, VCAM-1 (soluble Vascular Cell Adhesion Molecule), and sSELE (soluble E-selectin) in the diagnosis and prognostic evaluation of community-acquired pneumonia (CAP). METHODS: Pediatric patients with severe pneumonia (SP) were hospitalized and patients with mild disease (MP) were treated in the community. IL6, IL8, IL10, VCAM-1, and sSELE levels of the patients were investigated and compared with the age- and gender-matched healthy subjects. RESULTS: A total of 113 patients fulfilling the criteria for a diagnosis of CAP were enrolled in the study, 62 (54.8%) of which had SP and 51 (45%) had MP. MP and SP groups were significantly different in terms of IL8, IL10, and sSELE levels. Patients with SP and MP had significantly different WBC, ESR, and CRP values, as well. CONCLUSIONS: Besides classical acute phase parameters, inflammatory response parameters such as IL6 and VCAM-1 levels may be helpful in diagnosis of pneumonia. In terms of determination of disease severity in pediatric CAP, systemic inflammatory markers like IL8 and IL10 and adhesion molecules like sSELE seem useful in clinical settings.

Aykaç K, Karadag-Öncel E, Bayhan C, Tanir-Basaranoglu S, Akin MS, Özsürekci Y, Alp A, Cengiz AB, Kara A, Ceyhan M. Prevalence and seasonal distribution of viral etiology of respiratory tract infections in inpatients and outpatients of the pediatric population: 10 year follow-up. Turk J Pediatr 2018; 60: 642-652. The aim of this study was to investigate the prevalence and seasonal distribution of respiratory viruses in pediatric patients. Nasopharyngeal swab specimens, demographic and clinical information were collected from 1240 pediatric patients aged < 18 years between 2006 and 2015 in Hacettepe University Children`s Hospital. Multiplex RT-PCR (multiplex reverse transcriptase polymerase chain reaction) was performed to detect viral pathogens. A total of 1240 pediatric outpatients and inpatients who had been admitted to the hospital with symptoms of upper and lower respiratory tract infections (RTIs) were enrolled. Viruses were identified in 339 (27.3%) of cases, with the leading three viruses being respiratory syncytial virus (RSV, 74/339; 21.8%), human rhinovirus (62/339; 18.3%), and multiple viruses (56/339; 16.5%). Most of the patients were diagnosed with lower RTI (264/339; 77.8%) and antibiotics were administered to three quarters of positive patients (254/339; 74.9%). With an overall viral agent detection rate of 27.3%, the findings of the present study suggest that other respiratory pathogens, whether viral or bacterial, may also lead to hospital visits due to respiratory tract symptoms in children.
RESUMEN
OBJECTIVES: The increasing incidence of infections caused by drug-resistant Gram-negative organisms has led to a re-emergence worldwide. This study attempted to investigate the changes in resistance of Gram-negative bacteria to different classes of antibiotics and the treatment options for invasive infections. METHODS: A retrospective study was performed between January 2012 and January 2017 in a Turkish tertiary care university hospital. A total of 302 patients with Gram-negative bacteraemia (n=274; 90.7%) or meningitis (n=28; 9.3%) were identified and their demographic, clinical and microbiological features were evaluated. RESULTS: A total of 302 patients with Gram-negative bacterial infection (bacteraemia or meningitis) were investigated. Klebsiella spp. was the most frequent causative agent (n=119; 39.4%), followed by Escherichia coli (n=67; 22.2%), Acinetobacter spp. (n=42; 13.9%), Pseudomonas spp. (n=41; 13.6%) and Enterobacter spp. (n=33; 10.9%). In total, 115 isolates (38.1%) were multidrug-resistant (MDR), 63 (20.9%) were extensively drug-resistant (XDR) and 6 (2.0%) were pandrug-resistant (PDR). Over the years, peak antibiotic resistance occurred in 2013, with an increase in the following years. CONCLUSIONS: These data indicate that the resistance pattern of Gram-negative bacteria may change over the years in hospital settings. Therefore, active surveillance of the resistance patterns of micro-organisms is necessary for better management of infections caused by highly resistant bacteria.
