[Frequency factor Her-2/neu overexpression in patients with breast cancer].

Her-2/neu is an oncogen related with a poor prognosis and high agresivity when overexpressed in breast cancer. Main objective was analyze the frecuency of positivity or negativity ofller/neu in patients with breast cancer after surgery and their relationship with hormone receptors. We perfomed a longitudinal, retrospective, descriptive and observational trial in all patients included in the Patology Service with a determination of Her-2/neu and hormone receptors analysis, between January 1st 2007 and December 31 st 2009.

Pleural effusion and ascites in severe preeclampsia: frequency and correlation with plasma colloid osmotic pressure and renal filtration function.

Background: Capillary leak with pleural effusion and/or ascites in severe preeclampsia (SP) may be a reason for low plasma colloid osmotic pressure (PCOP) and deterioration of renal filtration function. The objective of this study was to report the frequency of pleural effusion and/or ascites in patients with SP and to compare the correlation with PCOP and renal filtration function.

Methods: We conducted a cross-sectional study that included 92 pregnant women with SP.

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

[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.

[Active management of the premature membrane rupture in pregnancies of 34 to 37 weeks].
