The risk of hyperbilirubinemia in term neonates after placental transfusion - a randomized-blinded controlled trial.

OBJECTIVE: We aimed to demonstrate non-inferiority of delayed cord clamping (DCC) and cord milking (CM) in comparison to early cord clamping (ECC) in the incidence of hyperbilirubinemia requiring phototherapy. MATERIAL AND METHODS: 467 of maternal-foetal dyads were screened for eligibility. 389 term infants, of breastfeeding, non-smoking mothers were randomized to receive ECC ( < 40 s), DCC (1-2 min) or CM (4 times towards the neonate). The primary outcome was defined as hyperbilirubinemia requiring phototherapy. RESULTS: 307 patients were included in the analysis. CM did not increase the risk of phototherapy RR 11.27 95% CI (0.80; 2.04). Similar results were achieved when comparing DCC and ECC, RR 1.29 95% CI (0.82; 2.05). This was also true for CM vs DCC, RR 0.99 95% CI (0.64; 1.52). The prevalence of total serum bilirubin (TSB) at 24-48 hours was 10.8 mg/dL; 10.33 mg/dL and 11.39 in ECC, CM and DCC group respectively. Transcutaneous bilirubin (TcB) levels at 24-48 h were 7.58 mg/dL, 7.89 mg/dL and 7.60 mg/dL in the ECC, CM and DCC respectively. None of the neonates met exchange transfusion criteria or symptomatic polycythaemia. CONCLUSIONS: Our study suggests that placental transfusion is not associated with hyperbilirubinemia requiring phototherapy or exchange transfusion.

Assessment of interleukin-17A, C5a and RANTES for early diagnosis of neonatal sepsis - a preliminary study.

The aim of the present study was to investigate serum levels of novel markers: interleukin 17A (IL-17A), anaphylatoxin C5a and chemokine regulated upon activation normal T-cell expressed and secreted (RANTES) in neonates with clinically suspected early-onset neonatal sepsis (EONS), and to compare their values with those of non-infected neonates. Eighteen neonates with clinical signs and symptoms of EONS were enrolled in this study. Fifty healthy, non-infected neonates served as the control group. In all neonates serum levels of IL-17A, C5a and RANTES were measured by solid-phase sandwich enzyme-linked immunosorbent assay (ELISA). At the time of investigation serum levels of anaphylatoxin C5a were significantly higher in neonates with clinical symptoms of EONS than in non-infected neonates (median 65.35 vs. 50.4 ng/ml, p = 0.034), whereas levels of RANTES were similar and levels of IL-17A were under detection limit of the method. Based on these preliminary results, serum levels of C5a may be a useful marker of inflammation in early onset neonatal sepsis. Because traditional methods of microbiological diagnostics in EONS are frequently unsuccessful, the search for an alternative laboratory biomarkers is of great clinical importance. Thus, there is a strong need for further studies evaluating usefulness of this anaphylatoxin in EONS diagnosis on a larger group of patients.

Shoulder dystocia in diabetic and non-diabetic pregnancies.

OBJECTIVES: Shoulder dystocia remains an obstetric emergency. Maternal diabetes is considered to be one of the major risk factors for shoulder dystocia. The aim of this study was to analyze antepartum and peripartum risk factors and complications of shoulder dystocia in diabetic and non-diabetic women. DESIGN: We performed a retrospective analysis of 48 shoulder dystocia cases out of 28,485 vaginal deliveries of singleton, live-born infants over a 13 year period: 13 cases were diagnosed in diabetic women and 35 cases in non-diabetic women. SETTING: The study was conducted in the 2nd Department of Obstetrics and Gynecology, Medical University of Warsaw, Poland, from January 2000 to December 2012. RESULTS: Compared to non-diabetic women, diabetic patients had significantly higher pre-pregnancy body weight (83.4±23.8 kg vs. 62.5±10.9 kg, p=0.002), higher pre-pregnancy BMI (30.2±6.8 kg/m2 vs. 22.9±4.3 kg/m2, p=0.0003), and lower gestational weight gain (11.4±6.2 kg vs. 16.0±4.7 kg, p=0.01). Diabetic women with shoulder dystocia were more likely to deliver before completion of the 38th week of gestation (30.8% vs. 5.7%, p=0.02) and had a higher incidence of 1st and 2nd stage perineal tears compared with the non-diabetic group (23.1% vs. 0%, p=0.02). There were two cases of symphysis pubis dehiscence in non-diabetic women. Children of diabetic mothers had a significantly higher birth weight (4,425.4±561.6 g vs. 4,006.9±452.8 g, p=0.03). Children of diabetic mothers with dystocia were at significantly higher risk of peripartum injuries (92.3% vs. 45.7%). A significant difference was observed in the percentage of brachial plexus palsy (61.5% vs. 17.1%). Children of diabetic women experiencing shoulder dystocia were more frequently affected by Erb's brachial plexus palsy and respiratory disturbances. These children had an increased likelihood of birth weights above the 90th percentile (not necessarily reaching 4,000 g) compared to children born to non-diabetic mothers. CONCLUSIONS: Shoulder dystocia in women with diabetes mellitus during pregnancy was associated with earlier gestational age of labor, and these women were more frequently overweight. The newborns of diabetic mothers after shoulder dystocia appeared to be at an increased risk for perinatal morbidity compared to the newborns of non-diabetic mothers experiencing this complication.

Late preter cant neonatal problem?

BACKGROUND: The survival rate and quality of life of extremely low birthweight infants remain to be one of the main challenges of modern neonatology. Therefore, pre-term children born after 32 weeks of gestation with more normal birthweight, have become a relatively minor medical problem in comparison. OBJECTIVES: The aim of the following work was to compare the frequency of complications occurring in neonatal period in groups of late preterms and full-term neonates. METHODS: A group of 725 late pre-term babies, born between 34-36 6/7 GA, constituted the study group and has been analyzed retrospectively 5040 neonates born at term comprised the control group. The results were analyzed statistically using chi-square test. RESULTS: Respiratory disturbances were diagnosed in 178 neonates in the study group (24.55%), while in the control group in 138 cases (2.74%), p = 0.0000. Intrauterine infections were present in 92 neonates in the study group (12.69%) and in 327 infants in the control group (6.49%), p = 0.0000. Hiperbilirubinemia developed in 520 neonates in the study group (71.72%), and in 1895 babies in the control group (37.60%), p = 0.0000. CONCLUSIONS: (1) Respiratory disturbances, hiperbilirubinemia and intrauterine infections are more frequently observed in late preterms. (2) Increased morbidity in late preterm neonates prolongs the time of hospitalization.

The first case report of sulfonylurea use in a woman with permanent neonatal diabetes mellitus due to KCNJ11 mutation during a high-risk pregnancy.

Sulfonylureas (SUs) were proven to be more effective than insulin in most Kir6.2 permanent neonatal diabetes mellitus (PNDM) patients. We report SU use during pregnancy in PNDM. A woman with the R201H Kir6.2 mutation became pregnant at the age of 37. The patient had been on glipizide 30 mg for 3 yr; her glycosylated hemoglobin level was 5.8%. She was diagnosed with chronic diabetes complications and a congenital defect of the urogenitary tract-a bicornuate uterus with septum. Because the effect of SU on fetal development is uncertain, she was switched to insulin after the pregnancy diagnosis; however, the subsequent glycemic control was unsatisfactory, with episodes of hyper- and hypoglycemia. Thus, in the second trimester, the patient was transferred to SU (glibenclamide, 40 mg), which resulted in stabilization of glycemic control; glycosylated hemoglobin in the third trimester was 5.8%. Prenatal genetic testing excluded the Kir6.2 R201H mutation in the fetus. A preterm cesarean delivery was carried out in the 35th week. The Apgar score of the newborn boy (weight, 3010 g; 75th percentile) was 8 at 1 min. He presented with hypoglycemia, transient tachypnea of the newborn, and hyperbilirubinemia. The recovery was uneventful. No birth defects were recorded. His development at the ninth month of life was normal. In summary, we show a high-risk pregnancy in long-term PNDM that despite perinatal complications ended with the birth of a healthy child. SUs, which seem to constitute an alternative to insulin during pregnancy in Kir6.2-related PNDM, were used during the conception period and most of the second and third trimesters.
