[Predictor factors for the production of bronchopulmonary dysplasia in the preterm newborn].

Introduction: The bronchopulmonary dysplasia (BPD) is a lung illness chronicle that is developed in preterm newborn (PTNB) mainly, secondary to multiple factors of risk which have not been studied completely.

Objective: To determine the predictors factors (of risk factors) for the production of BPD in the PTNB of 28 at 36 weeks of gestational age.

Material And Methods: Eighty medical records from January 2004 to May 2006 of PTNB that there was received mechanical attendance to the ventilation (MAV) at least 24 hrs were reviewed retrospectively.

[Fetal echocardiography efficiency. Clinical experience].

Background: Congenital heart disease diagnostic has a high diagnostic precision with fetal echocardiography. This study has been reported in populations with high risk and with a sensibility of 86 to 99% and specificity of 91 to 100%.

Objective: To know sensibility and specificity of fetal echocardiography in high-risk pregnancies, and to describe types and frequency of congenital heart disease in utero.

[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.
