Effect of phototherapy on the ductus arteriosus diameter in extremely premature infants: A randomised controlled trial.

Patent ductus arteriosus (PDA) is a common complication among preterm infants (especially birth weight < 1000 g) and is closely associated with mortality and morbidity. Phototherapy (PT) is frequently used in the treatment of jaundice in premature infants in the first week of life. The relationship between PT and PDA has been investigated in a small number of studies but has not been fully elucidated because the studies had varying results. AIM: To examine the effect of PT on parameter (DA diameter, left atrial/aortic root ratio) in premature infants. METHODS: The study was planned as a prospective, randomised, double-blind study. A total of 83 infants <1000 g and < 30 weeks of gestation were included, and they were divided into two groups: the non-shielded and shielded groups. The babies included in the study were evaluated with a Doppler echocardiogram before and after PT. RESULTS: The hemodynamically significant PDA (hs-PDA) and left atrial/aortic root ratio significantly decreased in the shielded group, and the need for treatment due to PDA was significantly lower. The PT times of both groups were similar. CONCLUSION: Shielding application decreases the rate and severity of hs-PDA in extremely premature babies receiving PT.

Retinal findings similar to retinopathy of prematurity in a term-infant with congenital cytomegalovirus infection.

PURPOSE: To present a term-born infant with congenital cytomegalovirus (C-CMV) infection with an atypical retinal finding mimicking retinopathy of prematurity (ROP). CASE DESCRIPTION: A term-born infant was referred to our clinic due to a C-CMV infection. Fundoscopic examination of both eyes revealed a demarcation line at zone II level and peripheral avascular retina along the temporal retina. There was no chorioretinitis, no vitritis, and no retinal vasculitis. There was no history of oxygen supplementation. The demarcation lines in both eyes regressed spontaneously within 3 weeks without any sequelae. CONCLUSIONS: It has been known for many years that C-CMV infection may affect the eye, and chorioretinitis is the most common finding. In this case report, we presented an atypical ROP-like retinal finding in an infant with C-CMV infection. We think that the development of retinal vascularization may be affected by C-CMV infection. We hope that this finding may provide a clue for future investigations to understand the relationship between the pathogenesis of ROP and infection-induced inflammatory processes in prenatal and perinatal life.

Evaluation of the incidence, characteristics, and outcomes of pediatric chronic critical illness.

Our aim was to determine characteristics of children with chronic critical illness (CCI) admitted to the pediatric intensive care unit (PICU) of a tertiary care children's hospital in Turkey. The current study was a multicenter retrospective cohort study that was done from 2014 to 2017. It involved three university hospitals PICUs in which multiple criteria were set to identify pediatric CCIs. Pediatric patients staying in the ICU for at least 14 days and having at least one additional criterion, including prolonged mechanical ventilation, tracheostomy, sepsis, severe wound (burn) or trauma, encephalopathy, traumatic brain injury, status epilepticus, being postoperative, and neuromuscular disease, was accepted as CCI. In order to identify the newborn as a chronic critical patient, a stay in the intensive care unit for at least 30 days in addition to prematurity was required. Eight hundred eighty seven (11.14%) of the patients who were admitted to the PICU met the definition of CCI and 775 of them (87.3%) were discharged to their home. Of CCI patients, 289 (32.6%) were premature and 678 (76.4%) had prolonged mechanical ventilation. The total cost values for 2017 were statistically higher than the other years. As the length of ICU stay increased, the costs also increased. Interestingly, high incidence rates were observed for PCCI in our hospitals and these patients occupied 38.01% of the intensive care bed capacity. In conclusion, we observed that prematurity and prolonged mechanical ventilation increase the length of ICU stay, which also increased the costs. More work is needed to better understand PCCI.

The birth prevalence of selected major congenital anomalies: Six-year's experience in a tertiary care maternity hospital.

AIM: To evaluate the birth prevalence of specifically selected major congenital anomalies and to determine the correlated neonatal and maternal characteristics. MATERIAL AND METHODS: Data were collected retrospectively from hospital-based records of infants who were born at 22 completed weeks of gestation with a birth weight of more than 500 g in Zekai Tahir Burak Gynecology Training and Research Hospital between 2013 and 2018. Abortions, stillbirths, and terminated pregnancies due to fetal anomalies were excluded. Average annual prevalences were calculated for each selected major congenital anomaly. RESULTS: The total prevalence of congenital anomalies was 9.97 per 1000 in 102 379 live birth cohorts. The prevalence of severe congenital heart anomalies (SI-SII) was found as 21.1 per 10 000 live births. Down syndrome and meningomyelocele were the second and third most common anomalies, after congenital heart defects (13.87 and 9.97 per 10 000 live births, respectively). The prevalence of anomalies requiring specific surgery was found as 4.3 per 1000 live births. Congenital heart disease was present in 31.7% of patients who had Down syndrome. Atrioventricular septal defect accounted for 53.3% of congenital heart anomalies detected in Down syndrome. The prevalence of Down syndrome in babies of mothers aged 35 years and older was found as 46.67 per 10 000, which was significantly higher than in the group aged under 35 years (8.24 per 10 000). On the other hand, the prevalence of gastroschisis in babies of mothers aged 19 years and under was found as 5.81 per 10 000, which was higher than in the group aged 20 years and over (0.84 per 10 000). CONCLUSION: The actual magnitude of the number of births affected by congenital anomalies in Turkey is unknown. In our study, congenital heart diseases, Down syndrome, and meningomyelocele were found to be the most common congenital anomalies, respectively.

Presepsin and fetuin-A dyad for the diagnosis of proven sepsis in preterm neonates.

BACKGROUND: Diagnosis is the most strenuous step in the evaluation of neonatal sepsis. No gold standard diagnostic method is available except for blood culture. We aimed to investigate the role of positive and negative acute phase reactants, namely presepsin and fetuin-A, in the diagnosis of culture-proven late-onset sepsis. METHODS: A prospective, case-control study with the infants ≤32 weeks of age with a diagnosis of culture-proven late-onset sepsis was designed. Twenty-nine preterm infants with similar gestational and postnatal ages without sepsis constituted the control group. Serum values of presepsin, fetuin-A, C-reactive protein and interleukin-6 were evaluated at the enrollment, third and seventh days of the diagnosis in the infants with positive blood culture results. RESULTS: First-day presepsin values were significantly higher in the culture-positive infants than the control group [1583 ng/L (1023-1731) vs. 426 ng/L (287-589), p = < 0.0001]. Presepsin was found to have an 88.9% sensitivity and 88.9% specificity with a cut-off value of 823 ng/ml for culture-proven LOS in our study, and area under the receiver-operating curve was 0.939. Fetuin-A levels were similar between the study and control groups (p > 0.05). CONCLUSION: Presepsin may be an accurate marker for both diagnosis and monitoring of treatment response for culture-proven late-onset sepsis in preterm infants. However, fetuin-A does not seem to be a useful tool for the diagnosis of sepsis.

A promising, novel index in the diagnosis and follow-up of patent ductus arteriosus: Red cell distribution width-to-platelet ratio.

BACKGROUND: The role of red cell distribution width-to-platelet ratio (RPR) has not previously been mentioned in reports on patent ductus arteriosus (PDA). Our objective was to evaluate whether RPR would have a role in the diagnosis and/or prediction of pharmacological closure of PDA. METHODS: Preterm infants' gestational age ≤30 weeks and ≤1500 g who were given first ibuprofen treatment in the first week of life for hemodynamically significant PDA (hsPDA) were included in the study. The patients were matched for gestational age, birthweight, and sex. Patients were subdivided into two groups based on the response to medical treatment (open and closed PDA). Hemogram parameters were recorded before and after medical therapy. Groups were compared with regard to demographic and clinical characteristics and for three sequential hematological parameters. RPR was calculated. Patients with sepsis, anemia, perinatal asphyxia, and congenital/chromosomal anomaly were not included in the study. RESULTS: A total of 112 infants had medically treated hsPDA. Of those, ductus closed in 70 neonates (closed PDA). A total of 96 infants constituted the control group. Mean gestational age and birthweight of the patients were 28.9 ± 2.4 weeks and 1207 ± 372 g. While RPR was significantly increased, PCT was lower in both hsPDA and open PDA groups (P < 0.05 and P < 0.05, respectively). In multivariate analysis, high RPR (OR 3.3, 95% CI 1.438-5.872, P < 0.05) and RDS (OR 2.9, 95% CI 1.903-4.811, P < 0.01) were detected as independent risk factors for hsPDA. CONCLUSION: Red cell distribution width-to-platelet ratio and PCT may be promising supportive tools for the diagnosis and prediction of pharmacotherapy success.

Ultrasound guided percutaneous central venous catheters in neonatal intensive care unit.

Ates U, Derme T, Yilmaz Y, Özkan-Ulu H, Canpolat FE. Ultrasound guided percutaneous central venous catheters in neonatal intensive care unit. Turk J Pediatr 2018; 60: 478-481. Central venous catheters can be life-saving, especially in very low birth weight and sick newborns for whom peripheral access is difficult. However, the placement of a central venous catheter is technically difficult, especially in premature and newborn infants. To demonstrate the efficacy of placement of central venous catheters under guidance of ultrasonography (US) in neonatal intensive care units. The patients who were hospitalized in newborn intensive care unit and central venous catheters were placed into the internal jugular vein under the guidance of US were analyzed retrospectively. Successful cannulation rate was 90.9% in patients. The rate of success at first attempt was 68.1% in patients. The rate of three and more attempts was 9.1% in patients. The rate of complication was 9.1% in patients. The average intervention time was 8 minutes in patients. Central venous cannulation under the guidance of two-dimensional US is an effective method which can be easily and safely applied to low birth weight premature and newborn infants in newborn intensive care units.

Successful management of twin anemia/polycythemia sequence by syngeneic partial exchange transfusion.

Twin anemia/polycythemia sequence (TAPS) is characterized by large intertwin hemoglobin (Hb) differences without signs of twin oligopolyhydramnios. The spontaneous form complicates approximately 3-5% of monochorionic twin pregnancies. TAPS placentas are characterized by the presence of only very few and small unidirectional arteriovenous anastomoses, which allow a slow transfusion of blood from the donor to the recipient, gradually leading to highly discordant Hb levels. Neonatal morbidity in TAPS appears to be mainly limited to hematological problems at birth. Donor twins may be severely anemic and require blood transfusions, whereas recipient twins may be severely polycythemic and require partial exchange transfusion (PET). We herein report monochorionic twins with TAPS: the anemic twin was transfused with the blood concomitantly obtained from the polycythemic co-twin during PET. To our knowledge this is the first therapeutic approach using a recipient twin's whole blood as a donor source instead of a foreign blood donor. In this case, we have approached this recently (un)known form of chronic fetofetal transfusion from a different aspect. In our opinion, this will lead to new postnatal therapeutic approaches for optimal TAPS management.
