BACKGROUND: Brain injury leading to a persistent vegetative state during pregnancy involves difficult medical and ethical decisions. CASE: A 21-year-old multigravid woman entered a persistent vegetative state at 20 1/7 weeks of gestation after cardiac arrest with postanoxic brain injury from a suspected drug overdose. The clinical disciplines responsible for her case formed a collaborative care plan involving ventilator, nutrition, and medication support of the mother and regular fetal monitoring and ultrasound testing...

This study focused on the association between physical activity in the second trimester of pregnancy and adverse perinatal outcomes: low birth weight (LBW), preterm birth (PTB), and intrauterine growth restriction (IUGR). The study used a sample from the BRISA cohort, São Luís, Maranhão State, Brazil, which included women with singleton pregnancy, gestational age from 22 to 25 weeks confirmed by obstetric ultrasound performed at < 20 weeks, and re-interviewed in the first 24 hours postpartum (n = 1,380)...

Ultrasound is critical in many areas of medicine including obstetrics, oncology, and cardiology with emerging applications in regenerative medicine. However, one critical limitation of ultrasound is the low contrast of target tissue over background. Here, we describe a novel cup-shaped silica nanoparticle that is reminiscent of exosomes and that has significant ultrasound impedance mismatch for labelling stem cells for regenerative medicine imaging. These exosome-like silica nanoparticles (ELS) were created through emulsion templating and the silica precursors bis(triethoxysilyl)ethane (BTSE) and bis(3-trimethoxysilyl-propyl)amine (TSPA)...

OBJECTIVE: To summarize current knowledge about cesarean scar pregnancy and to provide a review about available managements of this serious pregnancy pathology. DESIGN: Review article. SETTING: Department of Gynecology and Obstetrics, District Hospital Náchod. RESULTS: Cesarean scar pregnancy is likely to be a result of impaired healing of the scar along with an increased affinity of trophoblast cells to extracellular matrix...

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...

OBJECTIVE: The aim of this study was to compare fixation and mobility of adjustable single-incision (Ajust) and standard transobturator midurethral sling (TVT-O) tapes based on postoperative ultrasound monitoring of the position of the tape at rest and at maximal Valsava (tape descent). The hypothesis was that fixation of SIMS Ajust is comparable to that achieved by the standard transobturator midurethral sling.

We report on an abdominal pregnancy in human immunodeficiency virus-positive mother, currently on antiretroviral therapy, which was discovered incidentally while training the obstetric ultrasound capacity building program. Although abdominal pregnancy is a rare form of ectopic pregnancy, it may be more common in women with HIV infection because they tend to have a higher rate of sexually transmitted diseases than the general population. The positive diagnosis of abdominal pregnancy is difficult to establish and is usually missed during prenatal assessment particularly in settings that lack routine ultrasound examination as is the case in most developing countries...

INTRODUCTION: Only little information is available on health-related quality of life (HRQoL) and its changes during the course of a normal pregnancy. We studied changes in HRQoL in a pregnant population during pregnancy and until one year postpartum in different body mass index (BMI) groups. MATERIAL AND METHODS: 750 pregnant women attending the first ultrasound examination before gestational week 14 were invited to participate in a longitudinal, communal-based survey...

Obstetric ultrasonography is an important and common part of obstetric care in the United States. The purpose of this document is to present information and evidence regarding the methodology of, indications for, benefits of, and risks associated with obstetric ultrasonography in specific clinical situations. Portions of this Practice Bulletin were developed from collaborative documents with the American College of Radiology and the American Institute of Ultrasound in Medicine (1, 2).

BACKGROUND: Clinically, once a woman has been identified as being at risk of spontaneous preterm birth (sPTB) due to a short cervical length, a decision regarding prophylactic treatment must be made. Three interventions have the potential to improve outcomes: cervical cerclage (stitch), vaginal progesterone and cervical pessary. Each has been shown to have similar benefit in reduction of sPTB, but there have been no randomised control trials (RCTs) to compare them. METHODS: This open label multi-centre UK RCT trial, will evaluate whether the three interventions are equally efficacious to prevent premature birth in women who develop a short cervix (<25 mm on transvaginal ultrasound)...

BACKGROUND: Obstetric ultrasound scans may fail to provide all the information that is needed because of poor visualisation. Two main causes of poor visualisation are addressed. These are poor foetal position and poor quality imaging due to beam distortion by overlying fatty tissue. METHOD: To improve communication with patients attending obstetric scans, a poster and leaflet were designed to explain these causes of inadequate scans. A questionnaire was used to assess the value of the poster...

PURPOSE: To establish sonographic reference ranges of the normal fetal thymus size between 17 and 38 weeks of gestational age (GA). METHODS: The study was conducted between April 1 and December 31, 2013. Low-risk singleton pregnancies without obstetrical and medical complications at the GAs between 17 and 38 weeks were recruited for thymus measurement. The fetal thymus was identified on transabdominal sonography at the three-vessel view. Maximal transverse diameter, perimeter, and thymus/thoracic ratio were measured...

Elizabeth Chapman, Suzanne Hagen, Helen Gallagher
BACKGROUND: Competent sonography is thought to include a unique combination of skills not yet fully defined. This presents challenges when recruiting the correct people for training. Skills are thought to include visuospatial perception and psychomotor skills, but little is known about the relationship between these aptitudes and scanning ability. This feasibility study explored such relationships, to identify evaluation techniques which may improve selection and recruitment. METHODS: A sample of 30 experienced ultrasound practitioners and 30 trainees at commencement and on completion of training were administered eight tests...

In human obstetrics, placental vascularisation impairment is frequent as well as linked to severe pathological events (preeclampsia and intra-uterine growth restriction) and there is a need for reliable methods allowing non-invasive evaluation of placental blood flow. Uteroplacental vascularisation is complex and animal models are essential for the technical development and safety assessment of these imaging tools for human clinical use but these techniques can also be applied in the veterinary context. This paper reviews how ultrasound based imaging methods such as 2D and 3D Doppler can provide valuable insight for the exploration of placental blood flow both in humans and animals and how new approaches such as the use of ultrasound contrast agents or ultrafast Doppler may allow to discriminate between maternal (non-pulsatile) and fetal (pulsatile) blood flow in the placenta...

MATERIALS AND METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: In France, premature birth concerns 60,000 neonates every year (7.4 %), half of them are delivered after spontaneous onset of labor...
