Inclusion criteria were presence of CDH; absence of fetoscopy; absence of karyotype abnormality; maximum of one major malformation associated with diaphragmatic hernia; ultrasound monitoring at the Obstetrics Clinic of Clinicas Hospital at the University of São Paulo School of Medicine, from January 2001 to October 2014...

Fetal neurology is evolving as an area of great interest in prenatal diagnosis and fetal medicine. The identification and diagnosis of brain damage prenatally has been a great challenge in obstetrics for many years. Investigations of fetal behavior in comparison with morphological studies led to the conclusion that fetal behavioral patterns directly reflect developmental and maturational processes of the fetal central nervous system (CNS). Four-dimensional (4D) ultrasound has greatly improved the assessment of the quality of the fetal spontaneous movements, and enabled a better evaluation of fetal behavior...

INTRODUCTION: 2-D ultrasound shear wave elastography (SWE) could be considered as a new noninvasive tool for monitoring fetal lung development based on evaluation of mechanical properties during pregnancy. Interesting results are available concerning the use of SWE on developing organs, especially on premature infants and animal models. The main objective in this study is to evaluate the feasibility of 2-D SWE in human fetal lungs between 24 and 34 weeks of gestation (WG). The secondary objective is to modellise fetal lung-to-liver elastography ratio (LLE ratio) and to assess variations between normal lung and lung surfactant-enriched after a corticosteroids course indicated for a threatened preterm labour (TPL)...

Diana W Bianchi
Circulating DNA fragments in a pregnant woman's plasma derive from three sources: placenta, maternal bone marrow, and fetus. Prenatal sequencing to noninvasively screen for fetal chromosome abnormalities is performed on this mixed sample; results can therefore reflect the maternal as well as the fetoplacental DNA. Although it is recommended that pretest counseling include the possibility of detecting maternal genomic imbalance, this seldom occurs. Maternal abnormalities that can affect a prenatal screening test result include disorders that affect the size and metabolism of DNA, such as B12 deficiency, autoimmune disease, and intrahepatic cholestasis of pregnancy...

OBJECTIVES: To assess the efficacy and safety of in utero aspiration for anechoic fetal ovarian cysts. METHODS: This multicenter, prospective, randomized open trial with two parallel groups included women from nine outpatient fetal medicine departments with singleton pregnancies ≥ 28 weeks of gestation, a female fetus with an ultrasound-diagnosed simple ovarian cyst, defined as a single fully anechoic cystic structure measuring ≥ 30 mm. They were randomly allocated to in utero cyst aspiration under ultrasound guidance or expectant management...

Importance: Prenatal and neonatal cystic kidney diseases are a group of rare disorders manifesting as single, multiple unilateral, or bilateral cysts or with increased echogenicity of the renal cortex without macroscopic cysts. They may be accompanied by grossly enlarged kidneys, renal oligohydramnios, pulmonary hypoplasia, extrarenal abnormalities, and neonatal kidney failure. The prognosis is extremely variable from trivial to very severe or even uniformly fatal, which poses significant challenges to prenatal counseling and management...

Harmonic imaging techniques have been applied in ultrasonic elasticity imaging to obtain higher-quality tissue motion tracking data. However, harmonic tracking can be signal-to-noise ratio and penetration depth limited during clinical imaging, resulting in decreased yield of successful shear wave speed measurements. A logical approach is to increase the source pressure, but the in situ pressures used in diagnostic ultrasound have been subject to a de facto upper limit based on the Food and Drug Administration guideline for the mechanical index (MI <1...

OBJECTIVE: To evaluate whether the presence of cervical funneling or intra-amniotic debris identified in the second trimester is associated with higher rates of preterm birth (PTB) in asymptomatic nulliparous women with a midtrimester cervical length (CL) less than 30 mm (i.e., less than the 10(th) percentile). METHODS: A secondary cohort analysis of a multicenter trial of women between 16 and 22 weeks with a singleton gestation and a CL less than 30 mm by transvaginal ultrasound randomized to either 17-alpha hydroxyprogesterone caproate or placebo...

BACKGROUND A case report of urethral diverticulum complicating pregnancy is presented. The diagnosis and management are challenging because of the rare nature of this condition, the varied presentations and differential diagnoses, and the possibility of misdiagnosis. CASE REPORT A 25-year-old primigravida with scheduled induction of labor at 39 weeks gestation due to gestational diabetes mellitus presented for a routine antenatal appointment at 38 weeks and four days. On digital cervical examination, she was found to have a large semi-solid anterior vaginal mass, shown by trans-vaginal ultrasound to have a nearly solid appearance of a 5×7 cm mass with septation...

OBJECTIVES: The primary aim of the study was to investigate intra- and inter-observer reproducibility of Uterine Artery (UtA) Pulsatility Index (PI) in the third trimester of pregnancy. The secondary aim of the study was to examine whether high maternal Body Mass Index (BMI) or gestational age (GA) influence the reliability of this measurement. METHODS: Singleton pregnancies in women with known BMI were recruited between 30(+0) and 40(+0) weeks. UtA PI Doppler measurements were performed prospectively, independently and blindly by two Fetal Medicine Foundation accredited operators...

Context: The human fetal adrenal (HFA) is an integral component of the fetoplacental unit and important for the maintenance of pregnancy. Low kisspeptin levels during pregnancy are associated with miscarriage, and kisspeptin and its receptor are expressed in the HFA. However, the role of kisspeptin in fetal adrenal function remains unknown. Objective: To determine the role of kisspeptin in the developing HFA. Design: Experiments using H295R and primary HFA cells as in vitro models of the fetal adrenal...

Fetal cardiac intervention (FCI) is a relatively new and continually evolving field, and, for select cardiac defects, offers the potential to alter the progression of the disease and improve outcomes. It is a procedure that requires a collaborative effort between maternal-fetal medicine, interventional cardiology and fetal echo/ultrasound specialists, as well as fetal and maternal anesthesiologists, nursing specialists, and social workers. This article reviews the most recently reported data and advances in FCI...
