Background: The available literature indicates that there are significant differences in maternal mortality according to maternal origin in high income countries. The aim of this study was to examine the trend in the maternal mortality rate and its most common causes in Spain in recent years and to analyse its relationship with maternal origin.
Methods: This was a cross-sectional study of all live births as well as those resulting in maternal death in Spain during the period between 2000 and 2018.
Article Synopsis
- Bardet-Biedl syndrome (BBS) is a genetic disorder characterized by various abnormalities affecting multiple organs due to issues with cilia, which are tiny hair-like structures in cells.
- The disorder typically manifests over time, with symptoms not becoming apparent until several years after birth.
- Prenatal ultrasound may indicate potential BBS if enlarged kidneys and extra digits (postaxial polydactyly) are observed.
Aim: To rule out maternal and pregnancy factors that may contribute to platelet count (PLT) changes in the first trimester of gestation and examine if there is any association between its levels and adverse perinatal outcome.
Methods: The study population included all patients from the first-trimester visit between 2013-2015 with pregnancy results. Linear multiple regression was constructed to rule out variables that may have a significant contribution to PLT.
There is an increased interest nowadays on ultrasound analysis of the fetal thymus. Abnormal fetal thymic growth have been associated with DiGeorge syndrome, conotruncal cardiac malformations, chromosomal abnormalities and adverse outcome in different perinatal conditions as intrauterine growth restriction, preterm birth and others. Different methodologies that measure the fetal thymus by ultrasound have been published, however there is not a consensus of which one is the most useful.

Objective: To describe the sonographic findings and perinatal outcomes in cases with prenatal ultrasound diagnosis of intraabdominal umbilical vein varix (UVV).
Methods: Retrospective study of cases with prenatal ultrasound diagnosis of UVV.
Background: Progress in echographic techniques, particularly, high-resolution echography and color Doppler, as well the higher deep on knowledge and systematization in fetal anatomy exploration, are the main responsible of the increased number of cardiovascular anomalies diagnosed prenatally.
Objective: To describe the sonographic findings and perinatal outcomes in cases with prenatal ultrasound diagnosis of intra-abdominal umbilical vein varix.
Material And Methods: A descriptive and retrospective study of cases with prenatal ultrasound diagnosis of umbilical vein varix.
Objective: To evaluate the perinatal outcome of selective termination in dichorionic twins discordant for congenital defect, performed at the Hospital General Universitario Gregorio Marañon.
Study Design: Twenty-eight dichorionic twins with an anomalous fetus were included from May 2008 to February 2011. Intracardiac KCl (1-2 ml; 15 mEq/ml) under ultrasonographic guidance was used in all procedures.
