The rapid changes that have taken place in recent years in relation to techniques used to image the fetal heart have emphasized the need to have a detailed knowledge ofnormal cardiac anatomy. Without such knowledge, it is difficult, if not impossible, to recognize the multiple facets of congenital cardiac disease. From the inception of fetal echocardiographic screening, the importance of basic knowledge of cardiac anatomy has been well recognized. The current machines used for imaging, however, now make it possible potentially to recognize features not appreciated at the start of the specialty...

This article reviews important features for improving the diagnosis of fetal arrhythmias by ultrasound in prenatal cardiac screening and echocardiography. Transient fetal arrhythmias are more common than persistent fetal arrhythmias. However, persistent severe bradycardia and sustained tachycardia may cause fetal hydrops, preterm delivery, and higher perinatal morbidity and mortality. Hence, the diagnosis of these arrhythmias during the routine obstetric ultrasound, before the progression to hydrops, is crucial and represents a challenge that involves a team of specialists and subspecialists on fetal ultrasonography...

Arachnoid cysts are benign space-occupying brain lesions that contain cerebrospinal fluid. Most cases are congenital in origin, caused by failed fusion of the arachnoid membrane early in fetal development. Cases are often incidentally detected on neuroimaging; however, rarely patients present with neuropsychiatric manifestations when cysts expand and cause a midline shift, compression of nearby brain tissue or cerebrospinal fluid compartments or both. We report a case of a 56-year-old woman with no past history or family history of psychiatric illness who developed acute-onset right-sided weakness, depressive symptoms, and other neuropsychiatric deficits...

BACKGROUND: Cystic fibrosis (CF) can be revealed during fetal life by diverse ultrasound digestive abnormalities (USDA) such as fetal echogenic bowel or fetal intestinal loop dilatation, nonvisualization of the fetal gallbladder (NVFGB) being rarely observed in isolation. Only 6 cases of CF revealed by isolated NVFGB have been reported so far in the literature. Furthermore, recent studies suggested that this sign is of poor predictive value for CF. METHODS: We report on the results of a 6-year French tricenter study on 1,124 cases of fetal USDA for whom a comprehensive molecular study was performed for CF...

BACKGROUND: In clinical practice, abnormal biochemical changes often occur in women who eventually develop preeclampsia (PE). The study aims to investigate whether maternal serum biochemical markers in the early third trimester can predict PE and neonatal birth weight. STUDY DESIGN: A retrospective case-control study was performed on 287 women who subsequently developed PE (mild = 139; severe = 148) and 143 healthy women. Fasting venous blood samples of all gravidas were drawn for routine biochemical markers screening in the early third trimester (28...

INTRODUCTION: Arthrogryposis is a descriptive term defining a sign. It describes a set of joint contractures, sometimes identifiable in utero, present from birth and nonprogressive. This term includes a heterogeneous group of diseases, of neurological, neuromuscular, genetic or mechanical origin. The common physiopathological mechanism is fetal immobility syndrome. Two types of classification have been developed: a clinical one (types I, II and III) and an etiological one. The main aim of this study was to define a standardized protocol for etiological investigation based on a descriptive analysis of the various etiologies identified in a population of children followed up for arthrogryposis...

OBJECTIVE: We aimed to evaluate congenital heart disease (CHD) cases according to EUROCAT subgroup classification that were diagnosed during the prenatal period in our center. METHODS: CHDs that were prenatally diagnosed using ultrasonography and confirmed by fetal echocardiography were reviewed over a 10-year period. Subgroup classification was finalized at the post-partum period in terms of the EUROCAT guide 1.3. Congenital heart defect subtypes and obstetric outcomes (gestational week at delivery, birth weight, gender, extracardiac structural abnormalities, karyotype results if performed) were analyzed...

Abnormal placentation often requires the involvement of a multidisciplinary team of medical caregivers. Practicing Obstetrics is a challenging and skillful duty. This is more obvious in cases of abnormal placentation, which represents one of the most dangerous and complex clinical conditions in materno-fetal medicine. Pathological placentation involves position and invasion abnormalities and represents a serious and potentially life-threatening condition for both the pregnant woman and the fetus. The dramatic increase in cesarean section rates is an important factor which could explain the rapid raise in abnormal placentation cases, which were considered rare a few years ago...

A HoBi-like pestivirus was first described in 2004 in a Brazilian fetal bovine serum that was exported to Germany. Nevertheless, it is believed that the virus had been present since the 1990's, when it was detected in buffalos of Brazilian origin. Reproductive and respiratory diseases have been reported since 2001 in cattle, and more recently, diseases accompanied by a clinical presentation of mucosal disease-like (MD-like lesions have been reported as well. In the present study, the authors reported the oldest case of MD--like in cattle, associated with a HoBi-like pestivirus infection...

Placental abruption is an important cause of feto-maternal hemorrhage, with significant impact on both fetal and maternal mortality. In most cases, it presents with abdominal pain and vaginal bleeding. However, vaginal bleeding may be absent with concealed intra-amniotic hemorrhage, as in cases with placenta previa, hence confounding this diagnosis. In such cases, imaging studies may be obtained to evaluate for abdominal pain in pregnancy; hence, radiologists should be aware of the ultrasound and magnetic resonance (MR) imaging appearance of intra-amniotic hemorrhage...

Foot and mouth disease is an economically important transboundary disease of wildlife and cloven hoofed animals including ruminants. In the absence of vaccination, detection of antibodies against structural proteins (SPs) of foot-and-mouth disease virus is an indicator of infection. In the present study, a rapid dot blot assay using gold nanoparticlees was developed for the detection of antibodies against SPs of FMDV. Commercially available FMD vaccine was used as a source of FMD antigen. After the synthesis of gold nanoparticles (GNPs), the GNP-dot blot assay was tested and was found very sensitive, as the detection of antibody was up to 10-4 of serum dilution...

INTRODUCTION: During pregnancy, thyroid peroxidase (TPO) antibodies may increase the risk of developing subclinical hypothyroidism (SCH). Both conditions appear to be associated to maternal-fetal complications. The objectives of this study were to analyze if a relationship exists between TSH and TPO levels during pregnancy and the potential effects on gestational and perinatal complications, and to assess whether detectable, but not positive, TPO levels have an impact on development of gestational SCH...

Abnormal maternal lipid profiles, a hallmark of increased maternal adiposity, are associated with pregnancy complications such as preeclampsia and gestational diabetes, and offspring long-term metabolic health is impacted as the consequence of altered fetal growth, physiology and often iatrogenic prematurity. The metabolic changes associated with maternal obesity and/or the consumption of a high-fat diet effecting maternal lipid profiles and metabolism have also been documented to specifically affect placental function and may underlie changes in fetal development and life course disease risk...

RATIONALE: Antenatal diagnosis of a fetal hepatic cyst is rare. Since in most cases the lesion is treated after birth by surgery only a few reports present a complete spontaneous resolution of an antenatally diagnosed hepatic cyst. PATIENT CONCERNS: A single hepatic cyst (1.34/1.47 cm) was diagnosed in a fetus at 36 weeks of pregnancy while mother was in labor. After an uneventful vaginal birth, a multidisciplinary evaluation of the newborn confirmed the presence of the cyst...
