OBJECTIVES: To compare the accuracy of the INTERGROWTH-21st (IG-21) with the Italian Society of Ultrasound in Obstetrics and Gynecology (SIEOG) abdominal circumference (AC) standards in the detection of small-for-gestational-age (SGA) fetuses in a high-risk population. MATERIAL AND METHODS: Our study included all pregnant patients with an increased risk of placental insufficiency that were seen in two Italian university hospitals between 2014 and 2015. The accuracy of IG-21 and SIEOG AC standards in the detection of SGA neonates was analyzed by means of the area under the receiver operating characteristic curve (ROC-AUC) at 4 gestational age intervals (24-27, 28-31, 32-35, >35 weeks)...

Postmortem magnetic resonance imaging (MRI) is emerging as a valuable tool to accompany traditional autopsy and has potential for use in cases when traditional autopsy is not possible. This case report will review the use of postmortem MRI with limited tissue sampling to differentiate between metastatic neuroblastoma and hepatoblastoma which could not be clearly differentiated with prenatal ultrasound, prenatal MRI, or emergent postnatal ultrasound. The mother presented to our institution at 27 weeks gestation after an obstetric ultrasound at her obstetrician's office identified a large abdominal mass...

BACKGROUND: Single intrauterine death (sIUD) in twin pregnancies is associated with a significant risk of co-twin demise and preterm birth (PTB), especially in monochorionic (MC) twins. However, it is yet to be established whether the gestational age at loss may influence the pregnancy outcome. The aim of this study was to explore the risk of PTB according to the gestational age at the diagnosis of sIUD. METHODS: A cohort study of all twin pregnancies from a large regional network of 9 hospitals over a ten-year period...

Anti-Ro/SS-A is one specific type of antinuclear antibodies. They are in the majority of cases associated with primary Sjögren syndrome (SS) but also in Systemic Lupus Erythematosus (SLE), rheumatoid arthritis (RA), and in healthy people. During pregnancy, they are mainly associated to congenital heart block (CHB) and neonatal lupus (NL). The aim of this study was to compare the rate of maternal and fetal complications between a series of anti-Ro/SS-A positive pregnant women prospectively followed. Forty-two anti-Ro/SSA antibodies positive pregnant women that were referred to our hospital between 2011 and 2015...

Zika virus is an emerging mosquito-borne (Aedes genus) arbovirus of the Flaviviridae family. Following epidemics in Micronesia and French Polynesia during the past decade, more recent Zika virus infection outbreaks were first reported in South America as early as May 2013 and spread to now 50 countries throughout the Americas. Although no other flavivirus has previously been known to cause major fetal malformations following perinatal infection, reports of a causal link between Zika virus and microcephaly, brain and ocular malformations, and fetal loss emerged from hard-hit regions of Brazil by October 2015...

Confirmation of pregnancy viability (presence of fetal cardiac activity) and diagnosis of fetal presentation (head or buttock in the maternal pelvis) are the first essential components of ultrasound assessment in obstetrics. The former is useful in assessing the presence of an on-going pregnancy and the latter is essential for labour management. We propose an automated framework for detection of fetal presentation and heartbeat from a predefined free-hand ultrasound sweep of the maternal abdomen. Our method exploits the presence of key anatomical sonographic image patterns in carefully designed scanning protocols to develop, for the first time, an automated framework allowing novice sonographers to detect fetal breech presentation and heartbeat from an ultrasound sweep...

Prior studies have suggested that obstetrical (OB) ultrasound in low- and middle-income countries has aided in detection of high-risk conditions, which in turn could improve OB management. We are participating in a cluster-randomized clinical trial of OB ultrasound, which is designed to assess the effect of basic OB ultrasound on maternal mortality, fetal mortality, neonatal mortality, and maternal near-miss in 5 low-income countries. We designed a 2-week course in basic OB ultrasound, followed by 12 weeks of oversight, to train health care professionals with no prior ultrasound experience to perform basic OB ultrasound to screen for high-risk pregnancies...

Congenital heart block (CHB) is rare disorder that has a higher mortality when associated with structural congenital heart defects. Very few cases have been reported in Sub-Saharan Africa (SSA). We present a case of complete CHB associated with a complex congenital heart defect in a neonate in Cameroon. A 1-month-old neonate in Cameroon was referred for the evaluation of bradycardia. The obstetrical ultrasound done during pregnancy revealed fetal bradycardia without further evaluation. Clinical examination showed well a developed neonate with bradycardia at 62 beats/minute, and mild cyanosis with oxygen saturation at 93% at room air...

Macrosomic fetuses are at increased risk of obstetric complications, and notably shoulder dystocia, responsible for a severe neonatal morbidity. In case of fetal macrosomia, three options are: (i) the elective cesarean delivery, but this is recommended only when the estimated fetal weight is≥4500g for diabetic women and 5000g for non-diabetic women; (ii) the expectative management, but children with birth weight≥4500 had significantly increased risk of perinatal mortality, neonatal asphyxia, trauma, and cesarean delivery; (iii) the induction of labor which, reducing the possibility of fetal growth, reduce the risk of cesarean delivery for cephalopelvic disproportion and shoulder dystocia...

INTRODUCTION: The antenatal diagnosis of open spina bifida (OSB), a neural tube defect, is predominantly made at the second trimester morphology scan by ultrasound detection of structural abnormalities resulting from the associated Chiari II malformation. Evidence has emerged suggesting that these structural abnormalities can be detected earlier, by examination of the posterior fossa as part of the first trimester nuchal translucency scan. In particular, absence of the intra-cranial translucency (IT) of the fourth ventricle has shown promise as a diagnostic marker of OSB, although the sensitivity and specificity of this finding varies widely in the literature...

Ventriculomegaly (VM) is a non-specific finding on fetal imaging. Identification of the specific aetiology is important, as it affects prognosis and may even change the course of current or future pregnancies. In this review, we will focus on the application of fetal MRI to demonstrate intracranial haemorrhage and ischaemic brain injury as opposed to other causes of VM. MRI is able to identify the specific aetiology of VM with much more sensitivity and specificity than ultrasound and should be considered whenever VM is identified on obstetric ultrasound...

Placental masses are uncommonly identified at the time of obstetric ultrasound evaluation. Understanding the pathologies presenting as placental masses is key for providing a differential diagnosis and guiding subsequent management, which may include additional imaging with magnetic resonance (MR) imaging. Potential benign entities include chorioangiomas and teratomas. Larger chorioangiomas can cause fetal cardiovascular issues from volume overload. Placental mesenchymal dysplasia has an association with fetal anomalies and detailed fetal evaluation should be performed when it is suspected...
