BACKGROUND: The major causes of maternal and neonatal mortality in the Philippines are hemorrhages and obstructed labor due to placental implantation abnormalities (PIAs), twin pregnancies and fetal malpresentations. All of which are all easily detected by ultrasound. However, women in rural areas and low-income groups do not have access to ultrasound during their prenatal care. We aimed to provide additional evidence on the benefits of handheld ultrasound (HU) for screening pregnancy related abnormalities in order to avert maternal and neonatal deaths...

BACKGROUND: Persistently high rates of cesarean deliveries are cause for concern for physicians, patients, and health systems. Prelabor assessment might be refined by identifying factors that help predict an individual patient's risk of cesarean delivery. Such factors may contribute to patient safety and satisfaction as well as health system planning and resource allocation. In an earlier study, neonatal head circumference was shown to be more strongly associated with delivery mode and other outcome measures, than neonatal birth weight...

BACKGROUND: It is unknown if universal second-trimester transvaginal ultrasound (TVU) cervical length (CL) screening in asymptomatic women with singleton gestations and no prior spontaneous preterm birth (SPTB) affects the incidence of symptoms of preterm labor (PTL) later in pregnancy. OBJECTIVE: To evaluate the incidence of threatened PTL before and after the implementation of universal second trimester TVU CL screening. STUDY DESIGN: This was a retrospective cohort study of all consecutive singleton gestations without prior SPTB presenting to obstetric triage for threatened PTL between 23 0/7 and 33 6/7 week in 2011 (1 January-31 December), and in 2014 (1 January-31 December) at Thomas Jefferson University Hospital (TJU) (Philadelphia, PA)...

One in 10 infants in the United States is delivered preterm (ie, before the 37th week of pregnancy), contributing to the significant burden on the national healthcare system. Nevertheless, a lack of agreement continues among obstetric professional societies on guidelines for standardization of the approach to the diagnosis and management of patients with symptoms of preterm labor (PTL). This disparity in consensus has likely resulted in poor identification of women at an increased risk for preterm birth (PTB)...

OBJECTIVES: Labor epidural analgesia failure may relate to nonmidline placement of epidural catheters. We hypothesized that greater deviations of the epidural catheter insertion point from the ultrasound (US)-determined midline would be associated with less effective labor analgesia. METHODS: A prospective ethically approved cohort study was conducted. Fifty-two healthy average-sized women receiving labor epidural analgesia, inserted by the landmark technique, were approached after delivery...

Introduction This prospective study aimed to define the angle of progression (AOP) in relation to the height position of the fetal head during the first stage of labour. It was investigated if it is possible to predict the mode of delivery or the duration of labour by AOP. Methods Influencing factors on delivery were head circumference, birth-weight, administration of oxytocin, epidural anaesthesia (EA) and parity, and their impact on AOP was analysed. AOP was calculated using three different formulas. Inclusion criteria were vaginal delivery of singletons in cephalic, occipito-anterior presentation...

OBJECTIVES: A narrow subpubic arch angle (SPA) has been associated with a higher risk of operative delivery and prolonged labor. The aim of this study was to evaluate the correlation between SPA and labor outcome in a cohort of women delivering a large-for-gestational-age (LGA) fetus. METHODS: An observational study involving two Italian tertiary centers (Parma and Rome) was carried out. Nulliparous women referred to the antepartum clinic between 35 and 39 weeks due to an increased risk of having an LGA fetus at birth were prospectively selected for the study purpose...

Separation of pubic symphysis during delivery is a rare complication resulting in considerable and prolonged morbidity for parturient women. The usual presentation is that of something giving way in the region of the symphysis pubis sometimes with an audible crack at the time of delivery. Unbearable pain on moving from side-to-side and on performing any weight-bearing activity (such as walking or climbing stairs) precludes ambulation in the immediate postpartum period. This could be accompanied by disruption of the sacroiliac joint, hemorrhage, or urine incontinence in severe cases...

Objective: Vesicouterine fistula (VUF) is an uncommon cause of female genito-urinary fistula. Most of these fistulas are due to lower segment uterine cesarean section (LSCS). Traditionally, open surgical repair has been the traditional treatment. However, laparoscopic repair of VUF is a minimally invasive technique and few case reports have been published with short term follow up. In the present study, we are presenting our long- term outcome of laparoscopic repair of VUF. Material and methods: A retrospective analysis of 8 patients with VUF was performed from 2010 to 2015...

Purpose: First, to describe a new method of assessing cephalopelvic disproportion by measuring the retropubic tissue thickness (RTT), and second, to determine whether RTT was associated with an eventual delivery by cesarean section. Methods: Three-dimensional transperineal ultrasound scans were performed on 129 laboring nulliparous women to obtain 3-dimensional volume datasets for assessing RTT. RTT was measured off-line by three operators (A, B, and C) as the shortest distance between the capsule of the pubic symphysis and the outer border of the fetal skull...

BACKGROUND AND OBJECTIVES: Unintentional dural puncture is one of the most frequent complications of the epidural technique. One previous study suggested that atypical sonoanatomy of the ligamentum flavum/dura mater unit may be a risk factor for this complication. In this study, we describe the anatomy of the lumbar spine, assessed by magnetic resonance imaging (MRI) and ultrasound, in women sustaining unintentional dural puncture during epidural catheter placement for labor analgesia...

OBJECTIVES: to assess the obstetrical and psychological effect of visual biofeedback using trans-perineal ultrasound (TPU) during the second stage of labor. METHODS: Visual biofeedback using TPU was performed prospectively during the second stage of labor in twenty-six low risk nulliparous women. Pushing efficacy was assessed by the angle of progression at rest and during pushing efforts before and after observing the ultrasound screen. Obstetrical outcomes included level of perineal tearing, mode of delivery and length of the second stage...

BACKGROUND: Parity is the greatest risk factor for the development of pelvic organ prolapse. The normally supported vagina is pulled up and back over the levator ani. Loss of vaginal angulation has been associated with prolapse and may represent injury to the vaginal supportive tissues. OBJECTIVE: We proposed and examined the following hypotheses: (1) pregnancy and delivery impact vaginal support, leading to loss of vaginal angle; (2) vaginal angulation is restored postpartum; and (3) uncomplicated vaginal delivery (VD) is associated with accelerated remodeling of the vaginal fibrillar matrix...

RATIONALE: Treatment of breast cancer during pregnancy (BCP) remains a challenge to physicians. Surgery and chemotherapy during pregnancy are widely used for the treatment of BCP. Herein, we reported 3 Chinese patients with BCP who underwent chemotherapy during pregnancy and were followed up for adverse effects. PATIENT CONCERNS: Three female patients (case 1, case 2, and case 3) of 37-, 32-, and 28-year-old with breast masses were enrolled. Case 1 had been pregnant for over 4 months, case 2 over 7 months, and case 3 for 7 months...
