Lack of correlation between hormonal blood levels and endometrial maturation in agonadal women with repeat implantation failure following embryo transfer from donated eggs.

Five women with ovarian failure who repeatedly failed to conceive following embryo transfer from donated eggs underwent endometrial development investigation. One endometrial biopsy was obtained on cycle days 19, 21, and 23 during three consecutive artificially induced cycles. All five patients had only early secretory changes on days 19 and 21. Histological evaluation on cycle day 23 revealed various developmental stages: two women had "in-phase" endometrium, two patients had adequately developed stroma but significantly retarded glandular maturation, and one women showed no progress. The histological findings were conclusive for a significant maturation delay and an impaired endometrial receptivity. There was a lack of correlation between the peripheral hormonal blood levels and the endometrial maturation.

Conservative treatment of ectopic pregnancy and its effect on corpus luteum activity.

Corpus luteum activity was monitored in 15 women undergoing nonsurgical management of ectopic pregnancy with local methotrexate injection followed by alternating oral methotrexate and citrovorum factor (group A, n = 8) or local methotrexate injection alone (group B, n = 7). All patients initially demonstrated a viable corpus luteum (plasma progesterone ranged from 1.4 to 19 ng/ml). The treatment was successful in 14, with the exception of one whose tube ruptured 11 days after local administration of methotrexate, despite a continuous decrease in beta human chorionic gonadotropin, 17 beta-estradiol and plasma progesterone levels. There seems to be no correlation between the success of the treatment and the behavior of beta human chorionic gonadotropin, 17 beta-estradiol and plasma progesterone. Three patients from group A and two from group B displayed an initial rise in beta human chorionic gonadotropin following the initiation of the therapy, but the corpus luteum response differed. In group B patients, 17 beta-estradiol and plasma progesterone levels increased in parallel with beta human chorionic gonadotropin. Group A patients displayed a continuous decrease in 17 beta-estradiol and plasma progesterone levels despite the elevation of beta human chorionic gonadotropin, suggesting a possible effect of the systemic methotrexate on corpus luteum activity.

Percutaneous catheter drainage of tubo-ovarian abscesses.

We present the successful treatment of tubo-ovarian abscesses in three young patients by continuous percutaneous drainage, inserted under the guidance of real-time ultrasonography using only local anesthesia. Each patient had been diagnosed laparoscopically as suffering from acute pelvic inflammatory disease, but had formed abscesses despite extensive broad-spectrum antibiotic therapy. One case involved a complication of the ovum pick-up procedure; the woman had tubo-ovarian abscesses with infected hematomas. Because the abscesses were localized anteriorly in the lower abdomen and did not reach the pouch of Douglas, they could not be drained through a posterior colpotomy. Ultrasound guidance allowed us to drain all the areas of the multioculated abscesses. We suggest that percutaneous abscess drainage be the initial treatment of choice for tubo-ovarian abscesses before laparotomy is considered.

Third-trimester uterine rupture after prostaglandin E2 use for labor induction.

Prostaglandin E2 is a powerful oxytoxic agent that reliably initiates labor, even in the presence of an unripened cervix. The very low incidence of obstetric and neonatal side effects contributes to its universal use. Only nine cases of uterine rupture during the third trimester of pregnancy after application of various prostaglandin E2 preparations have been reported in English. Although uterine rupture after prostaglandin administration is a very rare complication, no prostaglandin compound seems to be exempt from it.

Normal pregnancy complicated by vaginal ectopic trophoblastic implantation; a case report.

We describe a rare case of ectopic placental tissue, presenting as a vaginal tumor during normal intra-uterine pregnancy. Its clinicopathological features, and its possible relation to placental site trophoblastic tumors are discussed. To the best of our knowledge, this is the first case to be reported in the English literature of such a lesion occurring at this site.

Uterine rupture at term pregnancy with the use of intracervical prostaglandin E2 gel for induction of labor.

Prostaglandin E2 is a powerful oxytocic agent that reliably initiates labor, even in the presence of an unripe cervix. The low incidence of fetomaternal complication contributes to its universal use. We report a rare case of uterine rupture after intracervical application of prostaglandin E2 gel. Thus far no prostaglandin compound or method of administration seems to be exempt from such a complication.

Conservative approach to multiple pregnancy with intrauterine fetal death of one or more fetuses.

One of the less common complications of multiple gestation is intrauterine demise of one or more fetuses. Despite the many case reports in the literature, there are no firm guidelines regarding the management of this problem. We herein report the favorable outcome of the conservative approach we chose for managing four patients; two with twins, one with triplets and one with quadruplets (first report in the literature). Strict follow-up based on frequent physical examinations, ultrasonographic assessment of fetal growth and well being, and coagulation profiles is mandatory. Individualization of delivery dates and mode is recommended.

Evaluation of ketanserin as a tocolytic agent in third trimester pregnant rats.

Ketanserin, as a 5HT2 selective antagonist, was evaluated for its tocolytic effects in pregnant Charles River (CR) rats, at total doses of 1.5 and 3.5 mg/kg IU from day 22 to day 25 of pregnancy. After 18 hours of ethenyl estradiol induction, tocolytic evaluation was carried out by recording uterine activity. When compared to the control group, the administration of Ketanserin resulted in an apparent, nondose dependent suppression of uterine contractility.

Ultrasonic validation of residual bladder volume in postvaginal hysterectomy patients.

Transverse and sagittal bladder diameters were measured with real-time ultrasound in 80 patients (100 measurements) during the first 2 days of postvaginal hysterectomy to assess the residual bladder volume and compared with the catheterization volume for the same patients. The sonographic method, with a 97.7% specificity and a negative predictive value of 89.5%, proved to be specific enough to eliminate the necessity of routine catheterization for measuring residual bladder volumes of greater than or equal to 150 cm3, thus decreasing the incidence of some major postoperative complications that can occur due to unnecessary catheterization.

Primary paraovarian cystadenocarcinoma: clinical and management aspects and literature review.

Two cases of primary paraovarian-origin serous cystadenocarcinoma, one invasive and one of low malignant potential, are presented. Both were diagnosed in postmenopausal women and were initially treated surgically. As of this writing, both women have survived 48 months past their initial diagnosis and have no clinically detectable disease. Clinical aspects and management problems of this fairly recently identified and rare entity are discussed and the literature on primary paraovarian malignant epithelial tumors is reviewed.

Placental site trophoblastic tumors (trophoblastic pseudotumors): pathology and clinical importance.

Placental site trophoblastic tumor (PSTT), which can be regarded as a subtype of gestational trophoblastic neoplasia is discussed. The histopathological features include trophoblastic proliferation without the typical organization of the bilamelar cyto and syncytiotrophoblastic villus. Ultrastructural investigation has demonstrated a clone structural relationship between the infiltrating cells and those of the trophoblastic components of the normal human placenta. Clinical management should be based on the complete surgical resection of the mass and a follow-up by measuring the serum levels of beta-human chorionic gonadotropin fractions.

Ultrasonic assessment of the endometrium as a predictor of oestrogen status in amenorrhoeic patients.

Thirty consecutive amenorrhoeic patients were assessed with regard to the following: medical history, physical examination, pelvic ultrasonography, serum levels of 17-beta oestradiol (E2), other relevant serum hormones and the response to a progesterone challenge test. The results showed a correlation coefficient of 71% (P = 0.001) between the E2 levels and the endometrial width and of 52% (P = 0.03) between the testosterone levels and the E2 levels. Linear regression of endometrial width against E2 levels showed beta = 0.018 (R2 = 22%, P = 0.02). Patients with an endometrial width of 4 mm or less reported no bleeding or only scanty bleeding following progesterone and all the patients with an endometrial width of greater than 5 mm responded to progesterone with normal menstrual bleeding.

Abnormal thyroid function in hyperemesis gravidarum.

Thyroid function was evaluated in 41 consecutive women with hyperemesis gravidarum (HG). In 11, increased free thyroxin concentrations (FT4) were measured. After one week of conservative therapy, 4 patients with persistent emesis were treated with antithyroid agents. Three of these 4 displayed other signs of hyperthyroidism. Emesis resolved in the other 7 patients within a week of conservative therapy. FT4 levels also returned to normal in these 7 patients within several weeks. Thyrotropin-releasing hormone (TRH) was administered to 10 of the 11 patients. Abnormal TSH responses, suggesting varying degrees of autonomous thyroid function were noted in all 4 patients treated with antithyroid drugs and in 3 of the untreated patients. Underlying clinical signs and symptoms of hyperthyroidism should be sought in patients with HG. In the presence of persistent emesis, despite conservative therapy of at least one week's duration and the presence of abnormal thyroid function studies, the use of antithyroid agents should be considered.

Cytologic evaluation of hormonal dynamic in the postmenopause.

There is increasing evidence that the postmenopausal ovary retains some endocrine function and thus can contribute a certain extent to the persistence of the vaginal epithelium proliferation a long time after the cessation of menstruations. Vaginal cytology plays an important role in the assessment of the vaginal epithelium response to hormonal stimuli, though less accurate than the blood and the urine estimations. It was established that there was a good correlation between the vaginal cytology and the biochemical estimations [2]. The fact that vaginal cytology cannot distinguish the proliferative patterns induced by estrogens, progesterone and androgens is true. With this in mind we did a cytological study in postmenopausal women, using our classification for the cytological typing based on the depth of the epithelial atrophy. The findings are discussed with special reference to the ethnic origin, reproductive life and concurrent illnesses.

Transitory hypoadrenalism due to long-term treatment with antiovulatory compounds.

A considerable number of women receiving antiovulatory compounds or estrogens complain of weakness and fatigability, suggesting a state of clinical hypoadrenalism. For this reason, levels of plasma ACTH and plasma cortisol were determined in 25 women with such complaints both during treatment and at various intervals after cessation of this treatment. The results obtained showed that there was a significant inhibition of ACTH secretion during long-term treatment with antiovulatory compounds or estrogens, and in half of the cases, there was a delay in normalization of the pituitary-adrenal axis following interruption of the drug, supporting a state of transitory hypoadrenalism.
