Congenital uterine anomaly has been well established as cause of infertility and recurrent pregnancy loss. However, only few studies have reported the association of mullerian anomalies and adverse pregnancy outcome in third trimester. We are hereby reporting a case of 25-year- old female second gravida who presented at 36 weeks six days pregnancy with complaint of decreased foetal movements for the past two weeks. The female had previous history of multiple admissions on account of decreased foetal movements in the third trimester...

BACKGROUND: In an era of worldwide population displacement, recent studies have identified strong associations between social situations and perinatal outcomes among immigrants. Little is known about the effect of maternal social background on pregnancy outcomes. The Human Development Index (HDI) assesses the following dimensions of human development: life expectancy, education level and income. The objective of our study was to determine if maternal HDI may be used to identify women at increased odds of poor pregnancy outcomes...

INTRODUCTION: Antepartum stillbirth is often preceded by detectable signs of fetal compromise, including changes in fetal heart rate and movement. It is hypothesised that continuous fetal monitoring could detect these signs more accurately and objectively than current forms of fetal monitoring and allow for timely intervention. This systematic review aimed to explore available evidence on women's experiences of continuous fetal monitoring to investigate its acceptability prior to clinical implementation and to inform clinical studies...

REVIEW
Philip Steer
The introduction of continuous electronic fetal heart rate monitoring (EFM) in labour has coincided with a steady and remarkable fall in perinatal mortality. Whether this is cause or coincidence remains unclear because randomised trials have been underpowered. Attempts to improve the sensitivity and specificity of fetal compromise detection using fetal blood sampling and pH measurement, pulse oximetry, and fetal electrocardiogram analysis have failed to provide evidence of additional value in randomised trials...

INTRODUCTION: One indicator for fetal risk of mortality is intrauterine growth restriction (IUGR). Whether markers reflecting the impact of growth restriction on the cardiovascular system, computed from a Doppler-derived heart rate signal, would be suitable for its detection antenatally was studied. MATERIAL AND METHODS: We used a cardiotocography archive of 1163 IUGR cases and 1163 healthy controls, matched for gestation and gender. We assessed the discriminative power of short-term variability and long-term variability of the fetal heart rate, computed over episodes of high and low variation aiming to separate growth-restricted fetuses from controls...

INTRODUCTION: Several studies report a decrease of fetal heart rate (FHR) short-term variation (STV) after corticosteroids for improvement of fetal maturity and advice not to deliver a fetus for low STV within 2-3days after corticosteroids. However, literature is not unanimous in this respect. This study intends to asses STV longitudinally after corticosteroid administration. MATERIAL AND METHODS: A retrospective cohort study in a tertiary perinatal centre from 2009 to 2015 included all women who had been treated with corticosteroids at gestational age of 26-34 weeks, had a computerized cardiotocography (cCTG) before and after medication and did not deliver within 48h...

BACKGROUND: Visual inspection of cardiotocography traces by obstetricians and midwives is the gold standard for monitoring the wellbeing of the foetus during antenatal care. However, inter- and intra-observer variability is high with only a 30% positive predictive value for the classification of pathological outcomes. This has a significant negative impact on the perinatal foetus and often results in cardio-pulmonary arrest, brain and vital organ damage, cerebral palsy, hearing, visual and cognitive defects and in severe cases, death...

OBJECTIVE: Current uterine monitoring techniques have major drawbacks that could be avoided when using electrohysterography for uterine monitoring. Recently, a new electrohysterography method has been developed, providing a real-time tocogram on standard cardiotocography monitors. The diagnostic characteristics of this novel method need to be determined and compared to conventional methods We hypothesised that electrohysterography can perform better than external tocodynamometry due to the adhesive properties of the contact electrodes (less motion sensitive), and the improved signal acquisition through subcutaneous tissue (less obesity sensitive)...

Preterm delivery affects about one tenth of human births and is associated with an increased perinatal morbimortality as well as with remarkable costs. Even if there are a number of predictors and markers of preterm delivery, none of them has a high accuracy. In order to find quantitative indicators of the immediacy of labor, 142 cardiotocographies (CTG) recorded from women consulting because of suspected threatened premature delivery with gestational ages comprehended between 24 and 35 weeks were collected and analyzed...

BACKGROUND: Foeto-maternal haemorrhage (FMH), a gestational event that occurs before or during delivery, consists of a loss of foetal blood into the maternal circulation. FMH occurs more frequently during the third trimester or labour both in normal and complicated pregnancies. In the case of alloimmunisation, the maternal immunological response and the severity of the resulting foetal or neonatal disease depend on the amount of foetal blood that passes into the maternal circulation. The aim of this study was to determine FMH in the third trimester and at term of pregnancy and to evaluate the role of clinical and ultrasound markers in the prediction of FMH...

INTRODUCTION: Pregnancy induced hypertension (PIH), especially preeclampsia, is a state of extremely increased oxidative stress (OS), due to decrease of antioxidant capacity in comparison to normotensive pregnant women. The consequences of increased state of oxidative stress with hypertension disorder in pregnancy are disorder of placental blood flow, intrauterine hypoxia of the fetus and disturbance in transfer of O2 manifested as pathological ultrasound (US) parameters (amount of amniotic fluid and biophysical profile of fetus) and cardiotocography parameters (CTG)...
