[Vaginal birth after cesarean. A safe option?].

Objective: To compare the beginning and evolution of labor variables such as demographic characteristics, obstetric and perinatal outcomes of patients with vaginal birth after cesarean (VBAC).

Material And Methods: Observational, retrospective and retro elective trial purposes of comparative analysis, were divided into groups by the onset of labor; spontaneously versus induction and by the labor evolution; spontaneously versus conduction. Being analyzing by Student's T and Fisher test.

[Chronic pelvic pain and cervical endometriosis after a subtotal hysterectomy].

The ectopic location of endometrial glands and stroma may cause the formation of a tumor known as endometrioma. It almost always occurs in the ovary, and due to its characteristic appearance has been called "chocolate cyst". Cervical localization of this disease is extremely rare, and when it occurs, tends to be an exocervical and/or endocervical injury, as a result of cervical procedures.

[Asynchronous birth in twin pregnancy. Literature review and case report].

Background: The incidence of multiple pregnancy has grown, some of these cases are attributed to assisted reproduction techniques, with the consequent increase of maternal-fetal morbidity. There have been few reported cases of delayed interval delivery with different perinatal outcomes. This is a case report of a double twin pregnancy with delayed delivery of the second fetus after birth of the first one within 15.

[Case report. Post cesarean section laparoscopic cholecystectomy for hydrocholecystitis].

Background: Acute cholecystitis is the second most common surgical emergency in pregnant women. Although laparoscopic cholecystectomy has been described previously in these cases, there is still controversy regarding the most appropriate moment in which to perform the procedure.

Objective: To describe the clinical presentation and management of a female with 36.

[Arterial thrombosis in ovarian hyperstimulation syndrome].

Ovarian hyperstimulation syndrome is an iatrogenic complication of controlled ovarian hyperstimulation. Its features are excessive growth of the ovaries and leakage of fluid from the intravascular space with ascites, hypovolemia and electrolyte imbalance, inducing a state of hypercoagulability, which can cause arterial or venous thrombosis. Thromboembolic events are the less common complications but they are the most serious.

[Accidents and incidents in gynecologic surgery].

Gynecologic surgery often entails meticulous dissection in areas close to the bladder, rectum, ureters and major vessels of the pelvis. The close anatomical relationship between these bodies that frequently makes are affected during pelvic surgery. When a complication occurs, it is vital to recognize and treat appropriately, emphasizing that gynecologists should handle its own complications and when they exceed the capacities of their own specialty, as in the case of unusual or complex lesions, should be sent assistance of a colleague in another specialty to solve the problem.

[Results' analysis of estradiol and progesterone supplementation in luteal phase vs progesterone alone in an assisted reproduction program].

Objective: To correlate estradiol and progesterone concentrations in luteal phase with pregnancy rates, and to determine the real value of estradiol administration during luteal phase support.

Patients And Methods: In a prospective and comparative study, 69 patients who underwent IVF-ET program were divided in two groups: group 1 (n = 32) received luteal phase support only with progesterone and group 2, (n = 37) luteal phase support with estradiol and progesterone. Ovarian stimulation was made with recombinant FSH and GnRH analogues (agonists or antagonists) and 24 hours after oocyte retrieval we began luteal phase support: group 1 progesterone (in oily solution) 100 mg/day IM, and group 2 same progesterone doses plus 2 mg of estradiol valerianate.

[Azoospermia : In vitro fertilization results, using testicular biopsy and cryopreserved spermatozoa].

Testicular sperm extraction (TESE) by open testicular biopsy, has become, since the introduction of the ICSI in 1992, the corner stone in treatment for azoospermia. This study reports the outcome of patients with open testicular biopsy for ICSI procedure indicated by azoospermia. 16 patients with azoospermia (12 obstructive and 4 non obstructive).

[Conservative management of secondary ectopic abdominal pregnancy. Case report with literature review].

Abdominal pregnancy is a rare condition representing 1-2% of all pregnancies; early diagnosis is difficult, but the challenge is the advanced pregnancy with adequate clinical condition for conservative management. There are few cases in which conservative management can improve, even though when the abdominal pregnancy is secondary to ruptured interstitial localization. A case of secondary (interstitial) abdominal pregnancy with conservative management and post-operative eventful for the mother and fetus is discussed.

[Maternal morbidity in adolescent pregnancy].

Objective: To evaluate the maternal morbidity in < or = 16 year old pregnant teenagers.

Material And Methods: A prospective study of the reviewed cases was carried out from June 1998 to May 1999. All pregnant teenagers which attended the Coordination for the Attention of the Teenage Patient and whose pregnancy came to term during the study period were included.

[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.

[Perinatal outcome in patients with meconial amniotic fluid in labor].

Purpose: To evaluate the perinatal morbidity and mortality with the presence of meconial amniotic fluid.

Material And Methods: Retrospective study of case review, performed from 1st of June 1995 to May 1997. The patients included were at delivery, with a pregnancy of 32 weeks or older and had meconial amniotic fluid.

[Emergency cerclage].

Objective: To evaluate the maternal and fetal morbility as well as the odds and conditions of pregnancy when performing an emergency cerclage.

Material And Methods: We performed a transversal, prospective and descriptive study of all the patients to which an emergency cerclage was performed in the Instituto Nacional de Perinatología between January 1, 1995 and December 31, 1996 having all the inclusion criteria. At such time 261 cerclages were performed in our Institute upon unique pregnancies being only 22 considered as emergency cerclages.
