OBJECTIVE: A paucity of effective interventions exists for the prevention of preterm birth (PTB). Renewed interest has focused on cervical pessaries, which have the benefits of being inexpensive, nonsurgical, and easily inserted and removed. In this study, we aim to describe our experience with this device in a Canadian tertiary care centre. Primary outcomes were rates of spontaneous or iatrogenic PTB before 37, 34, and 28 weeks gestation in pregnancies complicated by short cervix treated with cervical pessary...

OBJECTIVE: To evaluate the feasibility of predicting labor outcome using serial transperineal ultrasound (TPU) in the early active phase of labor. METHODS: This is a single center prospective observational study in a tertiary obstetrics unit in Hong Kong. Nulliparous women carrying singleton pregnancy at the onset of active phase of labor were recruited. Serial 3D volumes by TPU were acquired and then repeated after 1 and 2 hours, which were subsequently analyzed for fetal head symphyseal distance (HSD), angle of progression (AoP) and fetal head progression distance (PD)...

Although endometriosis is a common condition in women of reproductive age, the incidence of endometrioma in prior surgical incision sites is rare.We present a case of an abdominal wall mass in a female patient with a history of obstetrical surgery. The mass was visualized with ultrasound and computerized tomography, removed by wide excision, and identified via frozen section. This case demonstrates the importance of a thorough surgical and obstetrical history in any woman who presents with an abdominal wall mass...

OBJECTIVES: Women with rare intrauterine contraception (IUC) failures are advised to have their IUC removed because of the risk of poor obstetric outcomes with a retained IUC. Specifics regarding IUC removal in early pregnancy including techniques for removal, rates of success, and immediate pregnancy outcomes following removal are not well described, however. The objective of this study was to identify women with an IUC in early pregnancy examined at a tertiary care center with the primary objective of describing IUC removal attempts, IUC removal successes, and pregnancy outcomes at 20 weeks following IUC removal...

BACKGROUND: Obstetric ultrasound has become an indispensable part of antenatal care worldwide. Although the use of ultrasound has shown benefits in the reduction of maternal and foetal morbidity and mortality, it has also raised many ethical challenges. Because of insufficient numbers of midwives in Rwanda, uncomplicated pregnancy care is usually provided by nurses in local health centres. Obstetric ultrasound is generally performed by physicians at higher levels of healthcare, where midwives are also more likely to be employed...

BACKGROUND: Complete uterine rupture is a rare and severe intrapartum complication with high rates of maternal and fetal mortality. Asymptomatic uterine rupture is a very rare condition with one unique previous case described in the literature. Three-dimensional virtual models allow an immersive virtual reality of maternal-fetal structures with better understanding by the parents and the medical team. CASE: We demonstrate a case of asymptomatic rupture uterine with a large amniocele and protruded legs and umbilical cord at 28 weeks of gestation by using a 3-D virtual model from ultrasound scan data...

When breast cancer is diagnosed during pregnancy, treatment should be as close; as possible to what is used in non-pregnant patients. This requires accurate local and systemic staging: ultrasound (US) is used for local staging and allows adequate evaluation of the liver and pelvis, but chest and bones cannot be explored and imaging techniques involving exposure to ionizing radiation would be needed. However, since imaging techniques involving ionizing radiation and the use of radionuclides should be limited, whole body magnetic resonance imaging (WB-MRI) without administration of contrast agent represents a very interesting alternative, but limited data is available...

Hepatic hematoma is a condition of unrecognized origin which can become extremely serious and whose diagnosis is often made during perinatal autopsy. It is often characterised by nonspecific clinical manifestations and a long delay before biological presentation.The diagnosis is essentially based on ultrasound and treatment is often conservative.We here report a case of a full-term newborn with asymptomatic hepatic haematoma due to obstetrical trauma.

REVIEW
Federica Bellussi, Tullio Ghi, Aly Youssef, Ginevra Salsi, Francesca Giorgetta, Dila Parma, Giuliana Simonazzi, Gianluigi Pilu
Fetal malpositions and cephalic malpresentations are a well recognized cause of failure to progress in labor. They frequently require operative delivery, and are associated with an increased probability of fetal and maternal complications. Traditional obstetrics emphasizes the role of digital examinations, but recent studies have demonstrated that this approach is inaccurate and that intrapartum ultrasound is far more precise. The objective of this review is to summarize the current body of literature and provide recommendations to identify malpositions and cephalic malpresentations with ultrasound...

Roxane Holt, Jacques S Abramowicz
Quality assurance (QA) and safety are important components of obstetric imaging. Quality involves accreditation of the imaging unit as well as equipment inspection for function and image quality. The personnel working in the unit must demonstrate qualifications to perform, evaluate, and interpret the studies. Standardizing the required elements of the examination helps assure that a quality examination has been performed. QA and safety as well as physician requirements and equipment QA programs in ultrasound, computed tomography, and magnetic resonance will be discussed with an in depth look at ultrasound due to its more frequent use in pregnancy...

BACKGROUND: Abdominal pregnancy is a rare form of ectopic pregnancy that is frequently left undiagnosed by inexperienced obstetricians and radiologists. It is associated with higher risk of maternal hemorrhage at any gestation and more at advanced gestation. CASE PRESENTATION: We present the case of a 22-year-old sub-Saharan African woman, gravida 3 para 0, who was diagnosed with advanced abdominal pregnancy of 25 weeks' gestation by a transvaginal ultrasound after the failure of two medical terminations of pregnancy in the first and second trimesters and a series of repeated obstetric ultrasounds showing intrauterine pregnancy...

Point-of-care ultrasound (POCUS) has become a topical subject and can be applied in a variety of ways with differing outcomes. The cost of all diagnostic procedures including obstetric ultrasound examinations is a major factor in the developing world and POCUS is only useful if it can be equated to good outcomes at a lower cost than a routine obstetric examination. The aim of this study was to assess a number of processes including accuracy of images and reports generated by midwives, performance of a tablet-sized ultrasound scanner, training of midwives to complete ultrasounds, teleradiology solution transmissions of images via internet, review of images by a radiologist, communication between midwife and radiologist, use of this technique to identify high-risk patients and improvement of the education and teleradiology model components...
