Endometrial stromal sarcoma (ESS) is an aggressive uterine sarcoma. We report a case of a large endometrial stromal sarcoma in a 42 year nulliparous woman with chronic kidney disease presenting with acute urinary retention and irregular per vaginal bleeding. Ultrasound and Doppler imaging revealed a heterogeneous mass in the endometrial cavity with internal vascularity. Magnetic resonance imaging (MRI) revealed a large lobulated mass in the endometrial cavity extending into the vagina, causing local mass effect...

Many of the uterine infertility factors are associated with chronic endometritis. Its prevalence reaches 92.6%. Quality of endometrial transformation during the "implantation window" is the basis of successful fertility. In our retrospective comparative study of 101 in vitro fertilization (IVF) cycles, the efficacy of transvaginal Doppler ultrasound (TVDUS) in predicting successful implantation was evaluated. Inclusion criteria were as follows: age younger than 41 years and good quality of embryos. Exclusion criteria were as follows: 41 and older age, poor quality of embryos and uterine cavity lesions...

BACKGROUND: Results from uterine artery Doppler investigations suggest that the aetiology of late preeclampsia with fetal growth restriction may be more similar to the aetiology of early preeclampsia than with late preeclampsia without fetal growth restriction. We hypothesised that a small-for-gestational-age (SGA) birth in a late preeclamptic pregnancy may be associated with increased subsequent risk of early preeclampsia. We also studied effects of maternal factors on risks of preeclampsia recurrence...

In humans, intrauterine growth restriction (IUGR) is associated with vascular dysfunction, oxidative stress and signs of endothelial programming in umbilical vessels. We aimed to determine the effects of maternal antioxidant treatment with N-acetyl cysteine (NAC) on fetal endothelial function and eNOS programming in IUGR guinea pigs. IUGR was induced by implanting ameroid constrictors on uterine arteries of pregnant guinea pigs at mid gestation, receiving half of the sows NAC in the drinking water (from day 34 until term)...

INTRODUCTION: Uterine artery (UtA) Doppler velocimetry changes and increased arterial stiffness are associated with preeclampsia. We aimed to investigate the relation between UtA velocimetry changes and arterial stiffness in pregnant women. METHODS: Doppler velocimetry and photoplethysmographic digital pulse wave analysis (DPA) were performed in 173 pregnant women in the second or third trimester, where UtA Doppler pulsatility index (PI), diastolic notching, and UtA score (UAS) combining notching and high PI were calculated...

Identification of the fetus at risk of adverse outcome at term is a challenge to both clinicians and researchers alike. Despite the fact that fetal growth restriction (FGR) is a known risk factor for stillbirth, at least two thirds of the stillbirth cases at term are not small for gestational age (SGA) - a commonly used proxy for FGR. However, the majority of SGA fetuses are constitutionally small babies and do not suffer from adverse perinatal outcome. The cerebroplacental ratio (CPR) is emerging as a marker of failure to reach growth potential at term...

OBJECTIVES: Diffusion weighted magnetic resonance imaging (DWI) is a sensitive method to assess brain maturation or detect brain lesions, providing Apparent Diffusion Coefficient (ADC) values as a measure of water diffusion. Abnormal ADC values are seen in ischemic brain lesions, such as acute or chronic hypoxia. The aim of this study was to assess whether ADC values in the fetal brain were different in a group of fetuses exposed to severe vascular intrauterine growth restriction, compared to normal controls...

First-trimester screening may be a major advantage over a second-trimester approach since it opens prospects for early and more efficient interventions. The aim of the current study was to evaluate whether the measurement of maternal serum inhibin A, activin A and placental growth factor (PlGF) at three to four months gestation with the second-trimester uterine artery pulsatility index (PI) are useful in predicting preeclampsia in a group of nulliparous women. All the patients also underwent uterine artery Doppler examination to measure the PI at 22-24 weeks gestation...

Limited funding for medical technology, low levels of education and poor infrastructure for delivering and maintaining technology severely limit medical decision support in low- and middle-income countries. Perinatal and maternal mortality is of particular concern with millions dying every year from potentially treatable conditions. Guatemala has one of the worst maternal mortality ratios, the highest incidence of intra-uterine growth restriction (IUGR), and one of the lowest gross national incomes per capita within Latin America...

INTRODUCTION: In fetuses who are predicted to be at risk of catastrophic airway obstruction at delivery, the ex utero intrapartum treatment (EXIT) procedure is useful for securing the fetal airway while maintaining fetal oxygenation via placental circulation. Factors, including poor posture of the fetus and physician, narrow visual field, and issues of contamination in the aseptic surgical field, make fetal intubation during the EXIT procedure difficult. Herein, we report our experience of the usefulness of the GlideScope video laryngoscope (GVL) for intubation during the EXIT procedure...

INTRODUCTION: MCA and uterine artery Doppler PI are commonly used in the evaluation of IUGR. Targets: This retrospective pilot study aims to investigate whether MCA/UtA ratio may identify adverse outcome in late onset IUGRs. A cohort of 69 pregnancies affected with late IUGR which underwent labor induction according to local protocols was retrospectively revised on the relationship between MCA/UtA ratio at first observation and the following adverse outcomes: cesarean section for nonreassuring fetal status, birthweight (expressed as percentile and continuous values, umbilical artery pH, NICU admission and Apgar score < 7 after 1 and 5 min...
