Development of a birthweight standard and comparison with currently used standards. What is a 10th centile?

Introduction: Fetal growth charts are often used in clinical practice. It is important to understand the usefulness and the pitfalls associated with these tools. Without validation, it is difficult to ascertain if the cutoffs we intend are the ones we actually select.

Gestational age and fetal growth assessment among obstetricians.

Objective: We aimed to characterize gestational age assessment and fetal growth evaluation among obstetricians.

Methods: Observational, cross-sectional study. We applied a questionnaire to obstetrics specialists and residents, during a national congress on obstetrics.

Feasibility and reproducibility of transvaginal, transabdominal, and 3D volume reconstruction sonography for measurement of the corpus callosum at different gestational ages.

Objective: To compare the feasibility and reproducibility of transvaginal and transabdominal approaches, and 3D volume reconstruction sonography for measurement of corpus callosum (CC) length at different gestational ages.

Methods: Forty-six normal fetuses were examined by 2D and 3D ultrasound at 23-25, 27-28 and 31-32 weeks of gestation. Direct mid-sagittal views were obtained by either a transabdominal and/or transvaginal approach.

[Validity of classical fetal weight charts in the Portuguese population].

Purpose: to assess the validity of several fetal weight charts, commonly used in Portugal, to classify its population.

Methods: observational retrospective study. Singleton birth data was analyzed, from a two- year period (May 2008 to April 2010), from pregnancies with an ultrasound in the same institution, between the 8th and 14th gestational week.

Postpartum spontaneous rupture of a liver hematoma associated with preeclampsia and HELLP syndrome.

We report the case of a 28-year-old nulliparous woman who presented at 36 weeks' gestation with preeclampsia: high blood pressure, proteinuria and edema. Serum test results were normal and platelet count was 155 x 10(3)/mm(3). After 30 h the patient initiated severe epigastric pain and vomits, and lab tests presented a slight increase in liver enzymes.
