PURPOSE:  To evaluate cervical elastography strain pattern as a predictive marker for spontaneous preterm delivery (SPTD). MATERIALS AND METHODS:  In this case-control study cervical length (CL) and elastographic data (strain ratio, elastography index, strain pattern score) were acquired from 335 pregnant women (20th - 34th week of gestation) by transvaginal ultrasound. Data of 50 preterm deliveries were compared with 285 normal controls. Strain ratio and elastography index were calculated by placing two regions of interest (ROIs) in parallel on the anterior cervical lip...

OBJECTIVE: To investigate whether myometrial thickness (MT) to cervical length (CL) ratio could be used in the prediction of preterm birth (PTB) in singleton pregnancies presented with threatened preterm labor (TPL). METHODS: After 48 h of successful tocolysis, MT was measured transabdominally from the fundal, mid-anterior walls and the lower uterine segment (LUS) in 46 pregnancies presented with TPL. MT measurements were divided into CL, individually. The main outcome was PTB before 37 weeks of gestation...

BACKGROUND: Preterm labor is one of major obstetric challenges and can be predicted by cervical length at mid-trimester. In some settings, transvaginal ultrasound is not available and the screening and prevention of preterm labor will be suboptimal. We hope to find a correlation between other marker i.e. lower uterine wall thickness measured by transabdominal ultrasonography and cervical length measured by transvaginal ultrasonography in Thai pregnant women during 16-32 weeks of gestation...

INTRODUCTION: Amniotic fluid "sludge" has been associated with an increased rate of spontaneous preterm delivery before 35 weeks, a higher frequency of clinical chorioamnionitis, and histologic chorioamnionitis in a high-risk population. Only one study evaluating the use of antibiotics in the presence of amniotic fluid "sludge" showed reduced rates of spontaneous preterm birth at <34 weeks. The objective of this study was to evaluate routine antibiotic treatment in the presence of amniotic fluid "sludge" for prevention of preterm delivery...

Prematurity remains the most significant obstetrical complication with respect to long term newborn morbidity. Over the last few years there has been some progress made into the prediction and reduction of risk of preterm birth (PTB). Prediction has focused on identification of maternal characteristics that increase risk, on the evaluation of cervical length and the use of biomarkers [fibronectin, PAPP A, inhibin, αFP]. Of the preventive strategies, the use of progesterones in women perceived to be at risk is now commonplace and cervical cerclage or cervical pessaries are being used in selected cases...

BACKGROUND: Accurate diagnosis of preterm labour is needed to ensure correct management of those most at risk of preterm birth and to prevent the maternal and fetal risks incurred by unnecessary interventions given to the large majority of women, who do not deliver within a week of presentation. Intervention "just-in-case" results in many avoidable admissions, women being transferred out of their local hospital unnecessarily and most women receiving unwarranted drugs, such as steroids and tocolytics...

BACKGROUND: Preterm birth is a leading cause of neonatal morbidity and mortality worldwide; evidence-based strategies to decrease preterm birth are desperately needed. OBJECTIVE: The purpose of this study was to estimate which of three strategies for screening for shortened cervix in asymptomatic low-risk women is the most cost-effective in terms of prevention of preterm birth and associated morbidity. STUDY DESIGN: A decision analysis model was developed from available published evidence comparing three strategies in screening asymptomatic low-risk women for shortened cervix: (1) cervicometer with subsequent referral for transvaginal ultrasound, (2) transvaginal ultrasound screening, and (3) no screening...
