Objective Describe the classification system for assigning the cause of stillbirth in the Safe Passage Study, an international, multi-institutional, prospective analysis conducted by the NIAAA/NICHD-funded Prenatal Alcohol in SIDS and Stillbirth (PASS) Research Network. The study mission is to determine the role of prenatal alcohol and/or cigarette smoke exposure in adverse pregnancy outcomes, including stillbirth, in a high-risk cohort of 12,000 maternal/fetal dyads. Methods The PASS Network classification system is based upon 5 "sites of origin" for cause of stillbirth, further subdivided into mechanism subcategories; both are employed to assign an ultimate cause of death...

Introduction. To investigate whether maternal oral flora might be involved in intrauterine infection and subsequent stillbirth or neonatal death and could therefore be detected in fetal and neonatal postmortem bacterial cultures. Methods. This retrospective study of postmortem examinations from 1/1/2000 to 12/31/2010 was searched for bacterial cultures positive for common oral flora from heart blood or lung tissue. Maternal age, gestational age, age at neonatal death, and placental and fetal/neonatal histopathological findings were collected...

Perinatal death (PD) is a devastating obstetric complication. Determination of cause of death helps in understanding why and how it occurs, and it is an indispensable aid to parents wanting to understand why their baby died and to determine the recurrence risk and management in subsequent pregnancy. Consequently, a perinatal death requires adequate diagnostic investigation. An important first step in the analysis of PD is to identify the case circumstances, including relevant details regarding maternal history, obstetric history and current pregnancy (complications are evaluated and recorded)...

Rhabdomyomas are the most common primary cardiac tumors, especially seen during early periods of childhood. Fetaltype rhabdomyoma is a benign tumor described almost always in extracardiac locations. Although the natural history of the cardiac rhabdomyoma is to regress, the behaviour of the fetal-type rhabdomyomas when present in the heart is unknown with respect to its infrequency. Herein, we report a hemodynamically unstable female neonate with a single large intra-cardiac mass unresponsive to medical treatment, who underwent surgery...

Feto-maternal hemorrhage (FMH) is not an uncommon event during pregnancy with important clinical implications for both maternal and fetal outcomes. The diagnosis is often made using Kleihauer-Betke (KB) test. As FMH occurs transplacentally, examination of the placenta may contribute to the diagnosis of FMH. This retrospective case-control study aims to examine the placental features associated FMH in patients with known positive KB test results. When compared with KB negative placentas (n=88), KB positive placentas (n=49) had significantly higher incidence of pallor (6/49 vs 0/88, p=0...

BACKGROUND: Tranylcypromine is a non-selective inhibitor of monamine oxidase which also inhibits the reuptake of norepinephrine. Spontaneous hypertensive reactions to the drug have been reported. In sheep tranylcypromine has been shown to cause a dose-dependent reduction in uterine blood flow. A similar effect in a pregnant woman might induce constriction of the uterine arteries and temporary fetal hypoxia. CASES: MotherSafe is a state-based Teratogen Information service and currently provides counselling to around 22,000 consumers and healthcare professionals annually regarding exposures during pregnancy and breastfeeding We report on the outcome of 2 pregnancies in a patient treated with high dose tranylcypromine as well as pimozide, diazepam and alprazolam...

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...

We sought to describe the prenatal features and postnatal outcomes of the "criss-cross heart" (CCH) with crossing atrioventricular connections as encountered in 5 cases and to review the literature regarding fetal diagnoses of this lesion. We reviewed the clinical history and fetal echocardiograms of 5 patients with a diagnosis of CCH encountered in our institution from 2010 to 2015. Affected pregnancies were identified through the University of Alberta fetal cardiology database. Fetal and postnatal echocardiograms, prenatal and postnatal clinical records, autopsy, and surgical reports were reviewed...

BACKGROUND: Pentalogy of Cantrell (POC) is an extremely rare and complex congenital anomaly. Ultrasound is a valuable, safe, nonionizing, cost effective, widely available, and easily reproducible imaging tool and is indispensible in the diagnosis of POC. Despite the rarity of POC, it is imperative for a radiologist to be aware of its wide spectrum of presentation on ultrasound in first trimester of gestation. Most reported cases in literature till now have been sporadic. In this paper, we aimed to report for the first time in literature, a recurrent case of POC detected in the first trimester in a mother whose previous pregnancy also was terminated in the second trimester medically due to the ultrasound diagnosis of POC...

Right pulmonary artery to left atrium communication (RPALA com) is a fatal congenital heart disease with right-to-left shunting. We present a rare case of RPALA com that was prenatally diagnosed and confirmed by autopsy. We focus on some unique echocardiographic findings for prenatal diagnosis of RPALA com by reviewing our case and the literature. Asymmetric cardiomegaly with a pear sign and dilatation of the pulmonary artery might be useful for screening tests. A larger stalk with the pear sign, high-velocity of shunt flow, and absence of a dilated pulmonary vein might support the prenatal diagnosis of RPALA com...

Improving the counting of stillbirths and neonatal deaths is important to tracking Sustainable Development Goal 3.2 and improving vital statistics in low- and middle-income countries (LMICs). However, the validity of self-reported stillbirths and neonatal deaths in surveys is often threatened by misclassification errors between the two birth outcomes. We assessed the extent and correlates of stillbirths being misclassified as neonatal deaths by comparing two recent and linked population surveys conducted in Malawi, one being a full birth history (FBH) survey, and the other a follow-up verbal/social autopsy (VASA) survey...
