COMPARISON OF MATERNAL SERUM ESTRADIOL AND PROGESTERONE LEVELS IN PREGNANCIES AFTER INDUCED AND SPONTANEOUS OVULATION

Maternal serum estradiol and progesterone levels during the early 6th to 15th weeks of gestation, were measured by radioimmunoassay in 140 pregnancies following induction of ovulation with gonadotropins or clomiphene citrate. The levels were compared with those observed in 79 spontaneous pregnancies. Significantly higher levels were observed in gonadotropin and clomiphene citrate induced pregnancies (both P values < 0.001) between the 6th to 9th week of gestation as compared to spontaneous pregnancies. Steroid levels were similar in the two groups from the 9th week onwards. No statistically significant differences in steroid hormone values were observed in aborted and successful pregnancies within each group studied. We conclude that ovulation induction is associated with higher estradiol and progesterone levels until placental steroidogenesis starts

THE ROLE OF ANDROGENS IN THE LATE-PREMENOPAUSAL WOMAN WITH ADENOMATOUS HYPERPLASIA OF THE ENDOMETRIUM

To examine the possible role of androgens in hyperplasia of the endometrium, the concentrations of testosterone (T), androstenedione (A), dehydroepiandrosterone sulfate (DHEA-S), sex hormone-binding globulin (SHBG), estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH), were measured in peripheral venous serum obtained from 42 premenopausal women with adenomatous hyperplasia of the endometrium (group A) and from 18 women without hyperplasia (group B). In patients with hyperplasia of the endometrium, significantly higher peripheral venous concentrations were found for all androgens (P < 0.05) and estradiol (P < 0.001) than in control patients. In contrast, there was no statistically significant difference in the mean serum values of SHBG as well as in gonadotropins among the population of compared groups. We conclude that apart from the increased estrogenic activity in patients with adenomatous hyperplasia of the endometrium, androgens may play a significant role

The diagnostic value of laparoscopy in 2365 patients with acute and chronic pelvic pain

Objective: To discriminate the etiology in 2365 patients with acute and chronic pelvic pain (APP, CPP). Methods: Diagnostic laparoscopy was carried out in 736 patients (31.1%) with APP and in 1629 (68.9%) with CPP. In 315 patients (13.3%) the diagnostic procedure was extended to operative laparoscopy. Results: The most frequent laparoscopic findings in patients with APP were acute salpingitis and pelvic adhesions (22.8%) and ectopic pregnancy (19%), while in patients with CPP the most frequent findings were pelvic adhesions (35.4%) and endometriosis (24.6%). In 7.5% of patients with APP and 24% with CPP, laparoscopy did not reveal any pathological finding in the pelvis. Among the 315 patients in whom operative laparoscopy was carried out, 40% suffered from Apr and 60% from CPP. In the 446 patients (18.9%) without laparoscopic findings no treatment was given, while of the remaining 905 patients 40% were subjected to laparotomy and 60% received conservative treatment. The total incidence of side effects reached 4.7% and serious side effects resulting from emergency laparotomy occurred in 0.15% of patients with pelvic pain. Conclusion: Our results in a large group of patients with pelvic pain show that there are discrepancies in the incidence of laparoscopic findings between patients with APP and CPP. Discrepancies between the two groups of patients were also found during operative laparoscopy, the treatment administered after laparoscopic diagnosis and the complications encountered

The effect of early second stage bradycardia on newborn status

In the present study 45 patients with intrapartum cardiotocograms showing prolonged fetal bradycardia during the early second stage of labor were included. Bradycardia persisted for 180 s or more with either rapid or prolonged return to baseline, without loss of variability and rise of baseline fetal heart sate (FHR). The mean duration of bradycardia was 5.0 +/- 1.3 min. In the group with normal FHR tracings the rate of normal delivery (73.3%) was significantly higher than that of the group with fetal bradycardia (26.7%, P < 0.0001). We also noted a significantly higher rate of cesarean section (44.4%) in patients with abnormal FHR tracings, compared to that (11.1%) of parturients with normal FHR tracings (P < 0.001). In all cases blood samples were obtained from the umbilical cord artery, immediately after delivery. Only in two cases with abnormal FHR tracing umbilical cord artery was the pH less than 7.20. We conclude that in most cases, prolonged fetal bradycardia in the early second stage with the characteristics described above is well tolerated by a mature fetus.

SERUM LEVELS OF STEROID AND PLACENTAL PROTEIN HORMONES IN ECTOPIC PREGNANCY

The hormonal profiles of extra-uterine pregnancies (EP) were compared with the normal intra-uterine pregnancies (IUP), and threatened abortions (TA) of good outcome. In 45 cases of EP confirmed histologically, maternal serum human chorionic gonadotropin (hCG), pregnancy specific beta-1-glycoprotein (SP1), 17-beta-estradiol (E2) and progesterone (P) were measured serially before treatment by enzyme immunoassays (EIA). The same hormones were also determined in the control groups, 26 with normal IUP and 24 with TA. All four hormone levels in EP were significantly lower (P < 0.01 - P < 0.0001) than in normal pregnancies and threatened abortions of matched gestational age except the hCG and E2 in the fifth week of pregnancy. The mean values of E2 and P were found in the normal levels of luteal phase or slightly over them (8th-9th and 9th-10th weeks, respectively). No increase in the hormonal profiles of the above two steroids was noticed between 5 and 10 weeks’ gestation in EP. In conclusion: (a) The significantly lower values of hCG and SP1 in EP were confirmed; (b) the serial and concurrent hormonal measurements assure the verification of EP and the differentiation from normal IUP and TA of good outcome; (c) the ectopic implantation of trophoblast critically reduces its vitability to hCG and SP1 synthesis and it can only partially compensate for the reduction of corpus luteum function
