The study investigates the effect of sperm preincubation with FF on the fertilization rate in an IVF program. The oocytes inseminated with FF pretreated semen showed a significantly higher rate of fertilization. The percentage of cleavage and polypronuclear occurrence did not differ from the controls.
Intracranial hemorrhage during pregnancy is very rare. This catastrophic event has a poor prognosis and can contribute to maternal death for nonobstetrical reasons. The proper management during pregnancy remains controversial. Increasing awareness of the condition had been prompted by the fact that an acquired diagnosis is now usually available and a definitive and successful surgical procedure may be possible.
A study was undertaken to examine possible transplacental passage of Chlamydia trachomatis from pregnant women who were seropositive for chlamydia, but with no cervical C. trachomatis infection. Forty asymptomatic pregnant women, scheduled for diagnostic amniocentesis at 15-19 weeks of gestation, were tested for the presence of high serum IgA and IgG chlamydial specific antibodies and for cervical chlamydia infection. Five (12.5%) had both high serum IgA and IgG antibody levels and 10 (25%) had high serum IgG antibody levels. Overall, 15 (37.5%) had high serum chlamydia specific antibody levels (all were free of cervical chlamydial infection). The evaluation of the amniotic fluid specimens of these 15 seropositive pregnant women, who were free of cervical chlamydial infection, proved negative for direct C. trachomatis antigen detection and for chlamydial IgA and IgG specific antibodies. These negative results could be attributed to the lack of transplacental passage of C. trachomatis or to the antimicrobial activity of amniotic fluid against C. trachomatis, which has been previously described. The discrepancy between maternal infection and maternal serum antibody levels may suggest that the serologic test does not predict the presence of an antigen in the cervix.
A case control study was performed to examine possible morbidity associated with Chlamydia trachomatis in 15 pregnant women with idiopathic preterm premature rupture of the membranes (PROM; group A), and in two control groups, 35 healthy preterm pregnant women (group B), and 43 healthy pregnant women at term (group C). Serum C. trachomatis IgG and IgA specific antibodies were determined using the single serovar (L2) inclusion immunoperoxidase assay. There were no significant differences in the prevalence rate of elevated levels of chlamydia IgG specific antibodies (titer greater than or equal to 1:128) between pregnant women suffering from idiopathic preterm PROM, as compared to healthy preterm and term pregnant women (20, 28 and 26%, respectively). Nor were there any significant differences in the prevalence rate of elevated levels of chlamydia IgA specific antibodies (titer greater than or equal to 1:16) between pregnant women with idiopathic preterm PROM, as compared to healthy preterm and term pregnant women (20, 20 and 17%, respectively). These findings do not support the assumption that C. trachomatis may play role in preterm PROM.
GnRH agonists (GnRH-a) have recently been shown to exert an inhibitory effect on human reproductive functions, the mechanism for this effect being attributed solely to the desensitization of the pituitary gonadotropin receptors to GnRH-a. We present two cases where chronic treatment with a GnRH-a caused complete suppression of ovarian activity in vivo. The effect could not be counteracted by large hMG doses and resulted in high FSH plasma concentrations. Normal ovarian activity was restored only after withdrawal of GnRH-a.

The prostaglandins, F2 alpha and E2, are in extensive local use for the induction of labor. The main concern with oral and vaginal administration is the difficulty in controlling rapidly progressing labor and uterine hyperactivity. Herein we present a case where intravenous ritodrine was given as soon as hyperactivity and fetal heart rate decelerations were detected. With this treatment, the hyperactivity was controlled, fetal heart rate returned to normal and labor progressed normally to the birth of a healthy infant.
Performated carcinoma of the colon in pregnant women is a rare event. Only six cases have been reported in the literature, all except one in the recto-sigmoid. We present a case of perforated adenocarcinoma of the colon located above the peritoneal reflection and discuss the problem of diagnosis and management.
A new flexible protocol for the induction of recipient endometrial cycles is presented. For stimulation of endometrial growth, a fixed dose of conjugated estrogens, 3.75 mg/d was employed. The duration of the proliferative phase varied from 9 to 14 days, thus being adjusted to match the length of the follicular phase of the donor. Embryo transfer was performed on the fifth day of progesterone administration. Four term pregnancies resulted from 12 treatment cycles. In the conception cycles, the hormonal support was continued until the luteal placental shift occurred, regardless of gestational age.
We conducted a detailed literature search for the rare combination of scleroderma and pregnancy. Ninety-four patients were reported, 14 of whom died during the course of the pregnancy, mainly due to secondary renal and cardiopulmonary involvement. Out of the 95 fetuses, 19 were lost. Thus, when complications arise, the option of prompt termination of the pregnancy should be considered.

A case-control study was undertaken to examine the possible morbidity associated with Chlamydia trachomatis in 28 pregnant women having idiopathic premature contractions, in 35 healthy preterm pregnant women, and in 43 healthy pregnant women at term. Serum C. trachomatis IgG- and IgA-specific antibodies were determined by the single serovar inclusion immunoperoxidase assay. There were no significant differences in the prevalence rate of elevated C. trachomatis IgG-specific antibodies (titer greater than or equal to 1:128) between pregnant women suffering from idiopathic premature contractions as compared with healthy preterm and term pregnant women (11%, 28%, and 26%, respectively). The known prevalence rate in a normal healthy population is 23%. The prevalence rate of elevated C. trachomatis IgA-specific antibodies (titer greater than or equal to 1:16) was significantly lower in the pregnant women with idiopathic premature contractions as compared with the healthy preterm and term pregnant women (0%, 20%, and 17%, respectively; p less than 0.002 and p less than 0.012). These findings do not support the assumption that C. trachomatis has a role in premature contractions.
An unusual complication of spontaneous second trimester abortion which was unaided by external agents is presented. We found no similar case in the literature.
A rare case of transperitoneal ovum migration resulting in an intra-uterine pregnancy is presented. A woman with left congenital ovarian absence and a surgically removed right oviduct, conceived following microsurgical repair of left tubal occlusion.
Polycystic ovarian disease is characterized by menstrual disorders, infertility, obesity, and large ovaries. Large ovaries with multiple cysts are the direct cause of the high incidence of ovarian hyperstimulation during ovulation induction. Lately, gonadotropin-releasing hormone (GnRH) analogues have been employed to decrease ovarian steroidogenesis and thus reduce the incidence of ovarian hyperstimulation. In this study the ovarian size was ultrasonographically assessed during chronic GnRH analogue treatment, revealing a significant reduction in ovarian volume. This decrease in volume results in a reduced incidence of hyperstimulation, and we think the ultrasonic scanning can be effectively used to assess the success of GnRH treatment.
A case of nodular malignant lymphoma, small cleaved cell in both ovaries, tubes and peritubal tissue is reported in a 55-year-old nulliparous woman with primary clinical symptoms of dyspnea and chest pain. The disease was first diagnosed at laparotomy. The patient was treated by bilateral adnexectomy and chemotherapy. This is the third case of adnexal small cleaved cell nodular lymphoma reported in the literature. Clinical and pathological aspects of this relatively rare pathological entity are reviewed.
