Partial trisomy 9: prenatal diagnosis and recurrence within same family.

Trisomy 9 can be suspected and confirmed in the prenatal period since the 11-13.6 weeks of screening. In cases of partial trisomy 9, the diagnosis is important especially to counseling the couple due to the increased likelihood of recurrence in subsequent pregnancies.

[Atypical preeclampsia and perinatal success: a case report].

Preeclampsia is a multi systemic syndrome of variable severity, pregnancy specific, consequence of an abnormal vascular response to placentation, with increase in peripheral vascular resistance, stimulation of platelet aggregation, activation of the coagulation cascade, and endothelial dysfunction. In the majority of cases, it will present with gestational hypertension and proteinuria, after 20 weeks, nevertheless, in other cases, it has presented as an atypical form (with absence of hypertension and/or proteinuria) behaving like severe preeclampsia. We report the case of a patient, 32 year old primigravida, with a 26.

[Reversible long-duration contraceptives: an efficient strategy to reduce non-planned pregnancies].

Long-term contraception, reversible, have shown high rates of effectiveness and long-term compliance, with few contraindications. However, despite that Mexico has a variety of reversible contraception, most women still using less effective options. The resulting health benefits of contraception are important because they prevent unintended pregnancy, reduce the number of abortions and the incidence of death and disability related to pregnancy and childbirth complications.

[Placental acretism, a repercussion of modern obstetrics].

The evolution of obstetrics has led us to beneficial discoveries, and to new pathologies. The increase of cesarean section is due to elective cesarean section and cesarean section on maternal request, which have increased in popularity over the last past few years. Without condemning them, we have to take into account the benefits, as well as the complications that may arise from them, leading us to pathologies that were not frequent before, such as placental acretism, which today, is the second cause of obstetric hemorrhage worldwide.

[Initial values of human chorionic gonadotropin as a prognostic variable of pregnancy evolution in assisted reproduction].

Introduction: In assisted reproduction programs, once a pregnancy has been achieved, the power of predicting its evolution is important for the medical team as well as for the patient. The determination of pregnanediol or of placental protein 14 levels has been postulated as a predictive factor, however, the determination of hCG is, seemingly, the most adequate parameter for the detection of early developmental alterations during pregnancy.

Objective: To determine those predictive values of hCG which establish a prognosis concerning the evolution of pregnancy through the analysis of the values of this hormone on post-transference days 14 and 16, as well as to determine hCG values for multiple pregnancies.

[Changes in mitochondrial membrane potentials and its exponential relation with phosphatidylserine translocation in the plasma membrane as markers in the initial events of apoptosis: evaluation in different spermatic fractions].

Objective: To determine the integrity of the plasmatic membrane through phosphatidylserine (PS) translocation in two spermatic fractions and their correlation with the spermatic mitochondrial membrane potential.

Material And Methods: The analysis of both spermatic fractions was carried out through a discontinuous gradient separation with Percoli, in order to obtain two samples with high and low mobility (90-40%). Twelve patients were recruited for the initial evaluation of seminal parameters.
