The specialty of fetal surgery or fetal intervention is one of the most exciting emerging fields of modern medicine. It is made possible by decades of major developments in antenatal imaging, obstetric anaesthesia, fetal medicine, paediatric surgery and of course by the bold and novel practitioners willing to take new steps to advance the field. Beginning in the 1970s it has now reached a stage of maturity where there are several established in-utero procedures and countless clinical trials and studies to develop more...

REVIEW
R Townsend, A Khalil
Twin pregnancies are more likely to be affected by fetal growth restriction (FGR), preterm birth and perinatal loss. The management of fetal growth restriction in multiple pregnancy, particularly where only one fetus is affected is complicated by the need to consider the interests of both twins. Selective growth restriction in monochorionic (MC) twins is a pathophysiological process distinct from FGR in dichorionic (DC) pregnancies and management demands an understanding of the monochorionic placental structure and interdependent fetal circulations...

OBJECTIVE: Twin pregnancy is associated with 2-3 fold increased risk of stillbirth compared to singletons. Despite the fact that the growth pattern has been shown to differ in twins compared to singletons, it is controversial whether twin-specific growth charts should be routinely used. A major goal of prenatal ultrasound is to identify fetuses suffering from growth restriction at risk of stillbirth. The main aim of this study was to compare the performance of chorionicity-specific twin charts with singleton charts, both customized and non-customized, in the antenatal prediction of small-for-gestational age (SGA) stillborn and liveborn fetuses...

Objectives: To compare the grade of hydronephrosis between the antenatal and first postnatal ultrasound (US) and their clinical outcomes. Methods: This retrospective study included all cases of isolated hydronephrosis detected by antenatal US from August 2005 to February 2011. Hydronephrosis was classified based on the standard criteria into mild, moderate, or severe. Cases associated with other major congenital anomalies were excluded. All patients were followed-up postnatally and outcomes available were analyzed at one year of age...

The human face is a complex anatomic structure with an equally complex embryologic development. Derangement of the developmental process can result in various structural anomalies, which range from a mainly cosmetic deformity, such as cleft lip, to potentially life-threatening conditions such as arhinia. These anomalies (a) can occur as isolated anomalies; (b) can be associated with intracranial, spinal, or dental anomalies; or (c) can be a part of various syndromes, thus serving as diagnostic clues in such cases...

Infective endocarditis (IE) during pregnancy and subsequent cardiac surgery are rare and associated with a high risk of mortality for the mother and fetus. It is difficult to determine the right time for cardiac intervention when IE is diagnosed early in pregnancy. A 33-year-old previously healthy woman in the 11th week of pregnancy was diagnosed with IE and underwent surgical intervention. The cardiopulmonary bypass settings and the anesthetic drugs were carefully chosen. Although she was in good health, while being discharged, the fetus did not survive...

Background: Ephedrine was conventionally regarded as the first-choice drug to maintain maternal blood pressure during spinal anesthesia for cesarean delivery, due to its stimulant activity on α- and β-adrenergic receptors. Norepinephrine is a weak β-adrenergic and potent α-adrenergic receptor agonist. Therefore, it may be suitable for maintaining blood pressure with less chronotropic effects compared to ephedrine. Patients and Methods: One hundred and forty healthy patients having cesarean delivery under spinal anesthesia were randomized to Group N ( n = 61) who received a prophylactic bolus of norepinephrine 5 μg intravenous (i...

Transient receptor potential canonical channel 3 (TRPC3) proteins function as non-voltage-gated Ca2+ -permeable channels and play divergent roles in many processes of pathophysiology. The purpose of this study was to determine the relationship between TRPC3 expression and airway hyperresponsiveness and remodeling in ovalbumin-induced asthmatic Kunming mice. Mice were sensitized and challenged by ovalbumin to establish asthmatic model. Hematoxylin-eosin staining, hydroxyproline assay and isometric tracheal ring force measurement were used to evaluate airway remodeling and hyperresponsiveness in asthmatic mice...

BACKGROUND: In the last two decades, the consumption of drugs of abuse among women of childbearing age has experienced a significant increase and results from analyses of surveys concerning maternal intake of psychoactive prescription drugs during pregnancy indicate that the rates of intake are increasing each year. Analyses of biological matrices such as maternal hair and neonatal meconium have recently been used for assessment of gestational consumption and consequent prenatal exposure to drugs of abuse in high-risk groups of women METHODS: Maternal hair and neonatal meconium were analyzed by validated chromatographic mass spectrometric methodologies to disclose gestational use of drugs of abuse and psychoactive prescription drugs and consequent prenatal exposure in a cohort of 513 mother-newborn dyads at the Sant Joan de Déu Barcelona Hospital, Spain, during 2012- 2013...

INTRODUCTION: Recent developments have produced new CTG classification systems and the question is to what extent these may affect the model of FHR + ST interpretation? The two new systems (FIGO2015 and SSOG2017) classify FHR+ ST events differently from the current CTG classification system used in the STAN interpretation algorithm (STAN2007). AIM: Identify the predominant FHR patterns in connection with ST events in cases of cord artery metabolic acidosis missed by the different CTG classification systems...

PURPOSE: Fetal growth restriction (FGR) is a concerning health issue. However, studies on FGR management are limited due to its rarity. We aimed to evaluate the efficacy of the contraction stress test (CST) for FGR management. MATERIALS AND METHODS: A case-control retrospective study design. Our institute innovated CST in FGR management in 2017. We included women in their 33rd-40th week of pregnancy with a diagnosis of FGR and retrospectively divided them into groups: the CST group (FGR management with CST) and no CST group (FGR management without CST) before and after CST development...

Children born small for gestational age (SGA) have several life-long consequences. Previous epidemiological studies investigated from childhood to adulthood reported that a number of chronic diseases originate in the prenatal period. With the emerging era of obesity epidemic, more concerns are related to being obese than being short-statured in SGA children. The exact mechanisms are uncertain; however, growth hormone-insulin-like growth factor axis disturbance by fetal programming and accelerated postnatal weight gain contributed to central adiposity in SGA children...

BACKGROUND: Early during human development, the trophoblast lineage differentiates to commence placentation. Where the placenta contacts the uterine decidua, extravillous trophoblast (EVT) cells differentiate and invade maternal tissues. EVT cells, identified by expression of HLA-G, invade into uterine blood vessels (endovascular EVT), as well as glands (endoglandular EVT), and open such luminal structures towards the intervillous space of the placenta. Endoglandular invasion diverts the contents of uterine glands to the intervillous space, while glands near the margin of the placenta that also contain endoglandular EVT cells open into the reproductive tract...

Zika virus (ZIKV), a single-strand RNA flavivirus, is transmitted primarily through Aedes aegypti. The recent outbreaks in America and unexpected association between ZIKV infection and birth defects have triggered the global attention. This vouches to understand the molecular mechanisms of ZIKV infection to develop effective drug therapy. A systems-level understanding of biological process affected by ZIKV infection in fetal brain sample led us to identify the candidate genes for pharmaceutical intervention and potential biomarkers for diagnosis...

INTRODUCTION: The death of an infant during a pregnancy is profoundly traumatic, both for the parents and the involved healthcare professionals. Most research focuses on the impact of antenatal stillbirth with very little research examining the specific impact an intrapartum fetal death has on obstetricians. The aim of this study was to provide an in-depth qualitative exploration of the attitudes and responses that Irish Obstetricians have following direct involvement with an intrapartum fetal death...

The development of interventions to prevent congenital Zika syndrome (CZS) has been limited by the lack of an established nonhuman primate model. Here we show that infection of female rhesus monkeys early in pregnancy with Zika virus (ZIKV) recapitulates many features of CZS in humans. We infected 9 pregnant monkeys with ZIKV, 6 early in pregnancy (weeks 6-7 of gestation) and 3 later in pregnancy (weeks 12-14 of gestation), and compared findings with uninfected controls. 100% (6 of 6) of monkeys infected early in pregnancy exhibited prolonged maternal viremia and fetal neuropathology, including fetal loss, smaller brain size, and histopathologic brain lesions, including microcalcifications, hemorrhage, necrosis, vasculitis, gliosis, and apoptosis of neuroprogenitor cells...

Social deprivation negatively affects health outcomes but receives little attention in obstetric risk selection. We investigated whether a combination of (1) risk assessment focused on non-medical risk factors, lifestyle factors, and medical risk factors, with (2) subsequent institution of risk-specific care pathways, and (3) multidisciplinary consultation between care providers from the curative and the public health sector reduced adverse pregnancy outcomes among women in selected urban areas in the Netherlands...
