The Zika virus crisis exemplified the risk associated with emerging pathogens and was a reminder that preparedness for the worst-case scenario, although challenging, is needed. Herein, we review all data reported during the unexpected emergence of Zika virus in French Polynesia in late 2013. We focus on the new findings reported during this outbreak, especially the first description of severe neurological complications in adults and the retrospective description of CNS malformations in neonates, the isolation of Zika virus in semen, the potential for blood-transfusion transmission, mother-to-child transmission, and the development of new diagnostic assays...

REVIEW
Arne Ohlsson, Sanjay M Aher
BACKGROUND: Preterm infants have low plasma levels of erythropoietin (EPO), providing a rationale for the use of erythropoiesis-stimulating agents (ESAs) to prevent or treat anaemia and to provide neuro protection and protection against necrotising enterocolitis (NEC). Darbepoetin (Darbe) and EPO are currently available ESAs. OBJECTIVES: To assess the effectiveness and safety of ESAs (erythropoietin (EPO) and/or Darbe) initiated early (before eight days after birth) compared with placebo or no intervention in reducing red blood cell (RBC) transfusions, adverse neurological outcomes, and feeding intolerance including necrotising enterocolitis (NEC) in preterm and/or low birth weight infants...

BACKGROUND: Approximately 22% of women in the United States live in rural areas with limited access to obstetric care. Despite declines in hospital-based obstetric services in many rural communities, midwifery care at home and in free standing birth centers is available in many rural communities. This study examines maternal and neonatal outcomes among planned home and birth center births attended by midwives, comparing outcomes for rural and nonrural women. METHODS: Using the Midwives Alliance of North America Statistics Project 2...

BACKGROUND: Anemia is common in premature infants. Due to risks with red blood cell transfusions, many anemic infants are not transfused. The implications of this pathophysiologic status, especially at times of increased metabolic demand (enteral feedings), is not well understood. Near-infrared spectroscopy (NIRS) allows for the noninvasive determination of regional oxygen saturations (rSO2) in tissues such as the brain and mesentery, giving insight into their oxygen sufficiency. OBJECTIVE: We tested the hypothesis that during enteral feedings very low birth weight (VLBW) infants with a hematocrit ≤28% will experience a decrease in splanchnic rSO2 and splanchnic-cerebral oxygenation ratio (SCOR)...

Edwardsiella tarda (E. tarda) is a rare pathogen in humans, especially during the peripartum period. Only a few cases of fatal neonatal infection with E. tarda have been reported. Herein, we describe a case of maternal septicemia caused by E. tarda following peripartum chorioamnionitis. The mother developed septic shock, disseminated intravascular coagulation and a post-cesarean wound hematoma with abscess. Her condition improved with multidisciplinary therapy including blood transfusion, antimicrobial agents, recombinant thrombomodulin and surgical debridement...

BACKGROUND: Thiols are organic compounds containing sulfhydryl groups which exert antioxidant effects via dynamic thiol-disulfide homeostasis. The shift towards disulfides indicates the presence of oxidative environment. Thiol-disulfide homeostasis has not been evaluated in neonates. We aimed to evaluate dynamic thiol-disulfide homeostasis in preterm infants. METHODS: Preterm infants with birth weight less than 1500 grams (25-32 weeks of gestation) were included...

BACKGROUND: Cytarabine use during pregnancy carries a 5-7% risk of neonatal cytopenia. We report two cases of fetal myelosuppression following high-dose cytarabine administration for acute myeloid leukemia (AML). CASE 1: A 36-year-old G9P6 diagnosed with AML at 21 weeks was monitored for fetal anemia weekly and growth monthly. At 33 weeks (after 2 cycles), BPP was 2/10 and MCA PSV was elevated at 1.51 MoM. Urgent cesarean section was performed. The infant had an initial pH of 6...

The congenital dyserythropoietic anemias (CDAs) are a group of rare inherited blood disorders characterized by ineffective erythropoiesis as the principal cause of anemia. We present a child with CDA 1b-the rarest and least well-described type-due to a mutation in the C15orf41 gene. The patient presented with severe in utero and neonatal manifestations, typical peripheral limb anomalies as well as rarely reported cardiac manifestations, visual impairment, short stature, and hip dysplasia. Anemia was complicated by iron overload and pronounced extra medullary erythropoiesis leading to skull deformities...

Marcia Marchese
Lewis blood group antibodies, which are mostly naturally occurring and considered clinically insignificant, have rarely been documented as a cause of acute hemolytic transfusion reactions (AHTRs). This report presents two cases of AHTRs caused by anti-Lea occurring in postpartum black females (one group B, one group AB) whose pregnancies were complicated by preeclampsia. Neither anti-Lea was detected by automated solid-phase red cell adherence technology in pre-transfusion testing. Therefore, red blood cell units, compatible by electronic crossmatch, were issued and transfused...

OBJECTIVE: Endometriosis is defined as the presence of endometrial-like tissue outside the uterus, associated with pelvic pain and subfertility, affecting 0.6-10% of the general female population. The association between endometriosis and obstetrical outcomes is not well established. We aimed to evaluate whether endometriosis is associated with a higher incidence of obstetrical and neonatal complications. STUDY DESIGN: A retrospective cohort study of all deliveries in a university-affiliated tertiary hospital (2007-2014)...

BACKGROUND: Exchange blood transfusion (EBT) is a form of whole blood transfusion in which the total blood volume is replaced within a few hours. In perinatal and neonatal medicine, EBT is most often used in the management of severe anaemia or severe hyperbilirubinaemia in the first week of life. Hypocalcaemia, one of the common morbidities associated with EBT, is thought to arise from the chelating effects of the citrate commonly used as an anticoagulant in the donor's blood. This disorder manifests with muscular and nervous irritability and cardiac arrhythmias...
