[Clinical implications of basic research in preeclampsia: immunological tolerance].

Preeclampsia is one of the main causes of maternal and perinatal mortality in the world; however, the pathophysiologic pathways haven't been clearly elucidated. It is thought to result from a breakdown of maternal tolerance to paternal antigens in placenta that start an immune response against the trophoblast inducing a defective placentation and a hipoxic/isquemic environment which in turn triggers a systemic inflamatory response. This review gives an overview of the mechanims involved in maternal tolerance, how these are disrupted in preeclampsia, and how they contribute to the inflamatory response.

[Eclampsia, obstetric hemorrhage and heart disease as a cause of maternal mortality in 15 years of analysis].

Background: It has been described that 70% of all maternal deaths are provoked by obstetrical hemorrhage, infections, abortions, hypertension and delivery dystocies. Poverty, social exclusion, low level education and violence are important causes of maternal mortality.

Objective: To establish the changes in the maternal mortality in a term of 15 years in a hospital of assistance obstetrical complicated.

[Abdominal pregnancy care. Case report].

Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths.

[Diagnostic and frequency of fetal heart disease by echocardiography in pregnancies with high-risk factors].

Background: Fetal heart diseases are increasingly frequent. These are part of birth defects and, therefore, appear in early phases of the gestation. Diagnosis or early detection of functional and structural abnormalities of the heart allows to the obstetrician and the pediatric cardiologist to plan, in a timely manner, the treatment and prenatal and postnatal monitoring with the purpose of preventing complications.
