[Perinatal mortality at Hospital de Ginecoobstetricia No. 23 of Monterrey, Nuevo León, 2002-2006 period].

Background: Perinatal period begins at 22 gestational weeks and ends seven days after birth. Perinatal mortality is an important quality indicator of the obstetric and pediatric care available, and representative of the population's health service.

Objective: To know fetal, early neonatal, and perinatal dead rates, and them main mortality causes.

[Prenatal diagnosis of fetal cardiac defect].

Introduction: The prevalence of congenital cardiac defects is 8 per 1000 neonates, and it's different if high or low risk populations are studied. The fetal ultrasonographic increase prenatal detection but varies from 7 to 90%.

Objectives: To know the prevalence of fetal cardiopathy and detection in high risk pregnancies.

[Usefulness of Doppler ultrasonography to detect fetal anemia in rh alloimmunized pregnancies].

Background: pregnant women with Rh alloimmunization (RhA) are submitted to invasive procedures to assess fetal anemia (FA). Recently a non-invasive approach to FA diagnosis has been proposed using Doppler ultrasound (DU) to identify increased peak velocity of systolic blood flow (Vm) in the middle cerebral artery (MCA).

Methodology: eleven Rh alloimmunized pregnant women with serum red-cell antibody titers > 1:16 were included.

[Prenatal diagnosis of pentalogy of Cantrell associated to bilateral cleft lip. A case report].

The pentalogy of Cantrell is a rare congenital syndrome characterized by deficiency of the anterior diaphragm and defects of abdominal wall, the pericardium, the lower sternum, as well as congenital intracardiac abnormalities. It has usually a poor prognosis, but most cases have had incomplete variants of this syndrome, so it is important to make a prenatal diagnosis to determine the size of the wall defect and to establish a multidisciplinary management. Less than 90 cases have been reported in the world literature.
