Growth hormone--non multum sed multa (quality, not quantity).

In view of the recent availability of recombinant human growth hormone (GH) and reports of its ability to augment ovulation induction by exogenous gonadotropins, we have surveyed the reproductive physiological role of GH and the family of polypeptides that mediate its action. The clinical studies using GH to improve ovulation induction, although achieving a significant reduction in exogenous gonadotropin administration, show only minor benefits in terms of attainment of pregnancy. An explanation for this phenomenon is suggested, and we provide guidelines for whom GH should be recommended.

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.

Ectopic pregnancy, the new gynecological epidemic disease: review of the modern work-up and the nonsurgical treatment option.

Over the past few decades, the incidence of ectopic pregnancy has increased almost to the extent of an "epidemic disease." Early diagnosis of tubal pregnancy, with the aid of serum human chorionic gonadotropin, high-resolution ultrasound, and the more liberal use of laparoscopy, has dramatically reduced both maternal mortality and the need for radical surgery. Despite this, women with previous ectopic pregnancies still have reduced fertility potential. We report on some current aspects of the epidemiology, etiology, and work-up of ectopic pregnancy. In a review of 328 patients, gleaned from the literature, who were treated with various nonsurgical options, 283 (86%) were able to avoid surgery. The benefits, safety, and efficacy of the various treatment options are discussed, with appropriate recommendations for their use.

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.

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.

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.

Expression of estradiol and progesterone receptors by histologically normal endometria of women with postmenopausal bleeding.

Estradiol and progesterone receptor levels (RE2, RP) were measured in histologically normal endometria of women with postmenopausal bleeding (PMB) and the results were compared to those in histologically normal endometria of premenopausal and postmenopausal (PM) women and to those in pathological PM endometria. In histologically normal PMB endometria, RP levels were comparable to those in secretory premenopausal endometria and significantly higher than those in PM atrophic endometria. The RP levels in the former group correlated with the respective RE2 levels and the values of the ratio RP/RE2 occupied a mid-zone between those ratio values of normal premenopausal or pathological PM endometria on the one hand and normal PM endometria, on the other hand. The cytosolic/nuclear distribution of both receptor levels revealed that in both PMB and in pathological PM endometria, only a small fraction of the receptor was recovered in the nuclear extract. Expression of the RE2 and RP in the PMB and in the pathological PM endometria were associated with undetectable plasma E2 levels. These results indicate that histologically normal PMB endometria are biochemically active and suggest that endometrial growth and RE2, RP expression in PMB and pathological PM endometria are stimulated by a factor which acts distal to the RE2 acceptor.

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.

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.

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.

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.

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.

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.

Smoking out the oestrogens.

PIP: A tentative yet comprehensive review of the effects of smoking on reproductive capacity includes conception, sperm morphology, teratogeny and intrauterine growth retardation, cancer, timing of menopause, estrogen secretion, in vitro fertilization and estrogen metabolism. Smokers are estimated to take 3.4 times as long as non-smokers to conceive, and are reported to be less fertile. Spermatozoa are both abnormal morphologically and genetically compromised, in proportion to dose. Smokers have greater viremia in mumps and can get mumps orchitis. Smoking is said to cause impotence. Smoking increases risk of spontaneous abortion, intrauterine growth retardation and congenital abnormalities, in proportion to dose, starting with sidestream smoke. Smoke is directly toxic to the ova, and indirectly deleterious because it decreases estrogen secretion. Women smokers tend to the thinner, with lower estrogen levels, a factor in their lower success rates with in vitro fertilization. Smoking may speed up metabolic degradation of estrogen via the 2-hydroxylation pathway as well. Finally, smokers have earlier menopause, with accompanying osteoporosis and fractures.^ieng

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.

Distribution of total progesterone receptor levels in various segments and tissues of the normal human uterus: the effect of short-term estrogen administration.

Total progesterone receptor levels (TRP) were measured in various tissues and segments of normal human uteri in basal conditions (late proliferative phase, control group, n = 6) and after short term estrogen administration (test group, n = 8). Similar trends of distribution were observed in both groups in basal endometrial TRP levels along the longitudinal axis, i.e. the highest levels were found at the height of the body and the lowest at the height of the internal os. Differences were found in the trends of distribution of the TRP levels between the two groups along the transverse axis of the uterus at the height of the fundus. In the control group TRP levels in the functional endometrium were higher than those in the basal endometrium and myometrium. In the test group, however, the trend was reversed. Since the RP is estradiol induced and dependent, these results indicate the possibility of a selective estrogen effect on various segments or tissues in the human uterus.
