[Premature rupture of membranes in multiple pregnancies. Active echo-guided extraction of one fetus and continuation of the pregnancy. Report of 2 cases].

Late miscarriage is a well-known complication in multiple pregnancies. Two cases were presented with rupture of the membranes and prolapse of the cord with the death of the presenting fetus are reported. In both cases extraction of the presenting fetus was carried out at 21 weeks of pregnancy followed by cervical cerclage.

[Severe hypertriglyceridemia and acute pancreatitis in pregnancy. A case report].

We report the case of a 32-year old woman who developed major hypertriglyceridaemia complicated by acute pancreatitis at 35 weeks of pregnancy. Caesarean section was performed within 24 hours of admission. After delivery, hypocaloric parenteral feeding without lipid emulsion was initiated.

Prediction of individual response to controlled ovarian hyperstimulation by means of a clomiphene citrate challenge test.

A clomiphene citrate (CC) challenge test was carried out in 114 patients to evaluate the capacity of this test to predict the patient's individual response to controlled ovarian hyperstimulation (COH) performed with a gonadotropin-releasing hormone agonist and human menopausal gonadotrophins (hMG) for in vitro fertilization. The sum of follicle-stimulating hormone measured before and after CC intake, is the parameter that correlated best with subsequent response to COH. The upper limit of the reference value for this parameter, established by considering the CC challenge test performed on 26 patients who became pregnant, was 26.
