ABSTRACT
Introduction: Intravenous immunoglobulin (IVIG) has been widely used to treat the hemolytic disease of the newborn (HDN). Although it has been shown that IVIG treatment reduces the duration of phototherapy and hospitalization, the use of IVIG in hemolytic disease due to ABO incompatibility has been controversial in recent years. This study aimed to investigate the role of IVIG in the prevention of exchange transfusion in infants with ABO HDN who presented with bilirubin levels at or above the level of exchange transfusion. Materials and Methods: This study evaluated the data of infants with ABO HDN in the Turkish Neonatal Jaundice Online Registry. The infants with ABO HDN who met the total serum bilirubin level inclusion criteria (within 2-3 mg/dL of exchange transfusion or even above exchange transfusion level) were included in the study according to the guidelines from the American Academy of Pediatrics and the Turkish Neonatal Society. All patients were managed according to the unit protocols recommended by these guidelines and received light-emitting diode (LED) phototherapy. Infants who only received LED phototherapy, and who received one dose of IVIG with LED phototherapy were compared. Results: During the study period, 531 term infants were included in the study according to inclusion criteria. There were 408 cases in the phototherapy-only group, and 123 cases in the IVIG group. The demographic findings and the mean bilirubin and reticulocyte levels at admission were similar between the groups (p > 0.05), whereas the mean hemoglobin level was slightly lower in the IVIG group (p = 0.037). The mean age at admission was earlier, the need for exchange transfusion was higher, and the duration of phototherapy was longer in the IVIG group (p < 0.001, p = 0.001, and p < 0.001, respectively). The rate of re-hospitalization and acute bilirubin encephalopathy (ABE) was higher in the IVIG group (p < 0.001 and p = 0.01, respectively). Conclusion: In this study, we determined that one dose of IVIG did not prevent an exchange transfusion nor decrease the duration of phototherapy in infants, who had bilirubin levels near or at exchange transfusion level, with hemolytic disease due to ABO incompatibility.
ABSTRACT
: A major problem associated with immune thrombocytopenic purpura (ITP) in pregnancy is neonatal thrombocytopenia. We analyzed newborns born to mothers with ITP and examined predictive factors for thrombocytopenia. This retrospective study was performed in a single academic center from January 2007 to January 2018. Pregnant women with ITP and their babies are included. All neonates had a complete blood count and cranial ultrasound (USG) performed. Twenty seven neonates of 22 mothers were evaluated. A total of 23 (85%) of neonates were thrombocytopenic (<150â×â10/l) and in 20 (74%) platelet count was below 50â×â10/l. Median platelet count was 30 (4-300)â×â10/l. One baby experienced intracranial hemorrhage, eight (29.6%) had minor bleeding. When babies with and without minor bleeding were compared; no significant difference was found regarding maternal age, duration of ITP, lowest and 'before delivery' platelet count, treatment during pregnancy and splenectomy. Cutoff value of platelet count for bleeding was calculated as 27â×â10/l with a sensitivity of 0.88 and specifity of 0.79. Strong correlation for postnatal thrombocytopenia was detected among siblings. Although the incidence of neonatal thrombocytopenia might be high, the incidence of poor neonatal outcomes is extremely low. Neonatal thrombocytopenia does not rely on maternal profile. The occurrence of neonatal thrombocytopenia and bleeding may be a risk factor for subsequent pregnancies. We suggest that the cutoff value for neonatal platelet count for bleeding can be used for management and treatment of neonates born to mothers with ITP.

La cardiopatia congènita crítica (CCC) podría provocar cambios en la vasculatura de la retina. Sin embargo, no se dispone de suficientes datos sobre este problema en los recién nacidos. Se evaluaron los cambios en la vasculatura retiniana en una serie de 43 recién nacidos con CCC. Se los dividió en dos grupos según el tipo de CCC; grupo 1 (n= 18): CCC obstructiva izquierda y grupo 2 (n= 25): CCC obstructiva derecha. Se detectaron enfermedades vasculares retinianas en 21 pacientes (48,8%); estas fueron más frecuentes en el grupo 1 (p= 0,04). La patología más común fue la tortuosidad vascular retiniana, observada en seis pacientes (33,3%) del grupo 1 y en 4 (16,0%) del grupo 2. Ninguno de los 21 pacientes con cambios en la vasculatura de la retina requirió tratamiento durante el seguimiento. En un análisis multivariado, solo la CCC obstructiva izquierda estuvo asociada con el desarrollo de enfermedad vascular retiniana (P= 0,03, razón de probabilidades --#91;OR--#93;: 2,8, intervalo de confianza --#91;IC--#93; del 95%: 1,1-7,4). Los cambios vasculares retinianos son frecuentes en los recién nacidos con CCC.
Critical congenital heart disease (CCHD) may cause changes in retinal vasculature. However, there is lack of data in this issue in newborns. We evaluated retinovascular changes in a series of 43 newborn with CCHD. They were divided into 2 groups according to the type of CCHD; group 1 (n= 18): left obstructive CCHD and group 2 (n= 25): right obstructive CCHD. Retinovascular pathologies were detected in 21 patients (48.8%); it was more frequent in group 1 (p= 0.04). The most common pathology was retinal vascular tortuosity in 6 patients (33.3%) of group 1, and 4 (16.0%) in group 2. None of 21 patients with retinovascular changes required any therapy at follow-up. In multivariate analysis, only having a left obstructive CCHD was associated with the development of any retinovascular pathology (P= 0.03, OR: 2.8, CI95%: 1.1-7.4). Retinovascular changes are frequent in newborn patients with CCHD.

La canalización de los vasos umbilicales es un procedimiento frecuente en las unidades de cuidados intensivos neonatales, especialmente en los recién nacidos de muy bajo peso al nacer. Raras veces el catéter arterial umbilical se rompe; los fragmentos retenidos pueden provocar trombosis, infección, embolización distal e incluso la muerte. En este artículo, describimos el caso de un recién nacido con isquemia bilateral, clínicamente significativa, de las extremidades que se manifestó después de la extracción de un catéter arterial umbilical roto. Estaba recibiendo tratamiento vasodilatador junto con fibrinolíticos y anticoagulantes. La evolución fue favorable.
Umbilical vessel catheterization is a common procedure in Neonatal Intensive Care Units, especially in very low birthweight infants. Rarely, umbilical artery catheters break, and the retained fragments can cause thrombosis, infection, distal embolization, and even death. Herein, we describe a neonate with clinically significant bilateral limb ischemia developing after removal of a broken umbilical artery catheter. He was under vasodilator treatment in addition to fibrinolytic and anticoagulants. The evolution was favourable.

OBJECTIVE: To test the efficacy of probiotic and prebiotic, alone or combined (synbiotic), on the prevention of necrotizing enterocolitis (NEC) in very low birth weight (VLBW) infants. STUDY DESIGN: A prospective, randomized, controlled trial was conducted at 5 neonatal intensive care units in Turkey. VLBW infants (n = 400) were assigned to a control group and 3 study groups that were given probiotic (Bifidobacterium lactis), prebiotic (inulin), or synbiotic (Bifidobacterium lactis plus inulin) added to breastmilk or formula for a maximum of 8 weeks before discharge or death. The primary outcome was NEC (Bell stage ≥2). RESULTS: The rate of NEC was lower in probiotic (2.0%) and synbiotic (4.0%) groups compared with prebiotic (12.0%) and placebo (18.0%) groups (P < .001). The times to reach full enteral feeding were faster (P < .001), the rates of clinical nosocomial sepsis were lower (P = .004), stays in the neonatal intensive care unit were shorter, (P = .002), and mortality rates were lower (P = .003) for infants receiving probiotics, prebiotics, or synbiotic than controls. The use of antenatal steroid (OR 0.5, 95% CI 0.3-0.9) and postnatal probiotic (alone or in synbiotic) (OR 0.5, 95% CI 0.2-0.8) decreased the risk of NEC, and maternal antibiotic exposure increased this risk (OR 1.9, 95% CI 1.1-3.6). CONCLUSIONS: In VLBW infants, probiotic (Bifidobacterium lactis) and synbiotic (Bifidobacterium lactis plus inulin) but not prebiotic (inulin) alone decrease NEC.

Introduction: The predictive value of spiral artery flow Doppler measurements of a subsequent early miscarriage in first trimester pregnancy is explored here. Objective: The aim of this study is to determine uterine and spiral artery blood flow changes in first trimester subsequent miscarriages and correlate within the mechanisms of the Doppler indicies. Study design: The uterine artery and spiral artery pulsatility and resistance indexes, systolic and diastolic ratios, acceleration times, and blood flow of both the right and left uterine arteries were obtained by trans vaginal color Doppler ultrasonography in consecutive viable pregnancies between 5 and 12 gestational week. Women were subsequently classified as having continuing pregnancies or pregnancy loss before 20 weeks gestation. To predict subsequent pregnancy loss, Doppler findings were adjusted for maternal age, history of previous abortion, presence of subchorionic hematoma, embryonic bradycardia, and gestational age by means of multivariate logistic regression analysis. The cut-off values are used for the ROC curve. Results: Twenty-five pregnancies (11.7%) were spontaneously aborted before 20 weeks of gestational age. In 29 (13.6%) cases there were previously abortion history, 30 (14%) had bradycardia, and 37 (17.3%) had subchoronic hematoma. Regarding the parameters of uterine and spiral artery pulsatility and resistive index, acceleration time, systolic/diastolic ratios and blood flows, only uterine artery S/D low values were significantly associated with pregnancy loss in the multivariate logistic regression analysis (P = 0.0001,95% CI: 4.968-55.675). Conclusion: The uterine artery systolic/diastolic ratios have a predictive value for early pregnancy loss and seem to be useful as a marker. On the other hand, spiral artery changes could be so local that they cannot be determined by the parameters of spectral Doppler techniques. This suggests that uterine vascular bed alterations should be measured to understand the prognosis of early pregnancy loss during the first trimester.

OBJECTIVES: The goal was to investigate the effect of orally administered synbiotics on outcome of infants with cyanotic congenital heart disease (CCHD). METHODS: A prospective, blinded, randomized controlled trial was conducted to evaluate the effect of synbiotics on outcome of infants with CCHD. The infants with CCHD were assigned randomly to 2 groups. Infants in the study group were given synbiotic (Bifidobacterium lactis plus inulin) added to breast milk or mixed feeding until discharge or death. Infants in the placebo group were fed with breast milk or mixed feeding. The outcome measurements were nosocomial sepsis, necrotizing enterocolitis (NEC; Bell stage ≥ 2), length of NICU stay, and death. RESULTS: A total of 100 infants were enrolled in the trial: 50 in each arm. There were 9 cases of culture-proven sepsis (18%) in the placebo group and 2 cases (4%) in the synbiotic group (P = .03). Length of NICU stay did not differ between the groups (26 [14-36] vs 32 days [20-44], P = .07]. There were 5 cases of NEC (10%) in the placebo group and none in the synbiotic group (P = .03). The incidence of death was lower in synbiotic group (5 [10%] of 50 vs 14 [28.0%] of 50, respectively; P = .04). CONCLUSIONS: Synbiotics administered enterally to infants with CCHD might reduce the incidence of nosocomial sepsis, NEC, and death.
