[Increase S/D ratio in uterine artery as a predictor for preeclampsia in adolescent patients].

Background: Pregnancy during adolescence has been rising in the past years, and it is well known that preeclampsia affects teenagers, because maternal age and primigravida are risk factors. There are different ways and methods to predict preeclampsia, for example doppler velocimetry.

Objective: Determine S/D ratio of uterine artery in pregnant teenagers between 24-28 weeks and correlation with preeclampsia.

[Pelvic surgery as a predictive marker of the follicular response to ovulation inducers].

Objective: Comparing the follicular response in a group of patients with previous pelvic surgery submitted to in vitro fertilization.

Material And Methods: Patients who were going to be submitted to controlled ovarian stimulation and in vitro fertilization were included. Two groups were formed: one with those patients who had had a previous pelvic operation and the other with those patients who had not.
