摘要:
The induction of grand multiple gestations is a known complication of infertility treatments. The obstetric outcome in such cases has been very poor. We have evaluated, counseled, and performed first-trimester selective terminations for four patients, all treated with human menopausal gonadotropin, one with octuplets and three with quadruplets. In all cases, the gestations were reduced to twins. In two of the four cases, the pregnancy continued to near term without problem and resulted in the delivery of healthy twins. In the third case, pregnancy continued without problems for eight weeks, at which time renal agenesis was identified in one of the twins. In the fourth case, preterm labor five weeks later could not be stopped. Significant ethical issues must be addressed. We argue that selective termination in appropriate circumstances (eg, when the ability to carry the pregnancy to viability is very small) is ethically justified because it meets the criterion of least harm and most potential good.

摘要:
Our purpose was to assess factors that are associated with an increased rate of spontaneous abortion in pregnancies initiated by in vitro fertilization. Pregnancies were diagnosed by measurement of serum human chorionic gonadotropin (hCG) 15 days after embryo transfer. Of the 64 women who conceived, 47 delivered term infants, one patient delivered a stillborn at 22 weeks, 14 aborted in the first trimester, and two had pregnancies that implanted in the tube. Abortion rates were similar for women treated with human menopausal gonadotropin (24%; 12 of 54) and those who received clomiphene citrate (12.5%; one of eight). Two patients conceived after treatment with a combination of clomiphene citrate and human menopausal gonadotropin, neither of whom aborted. In 54 patients treated with human menopausal gonadotropin, there were no significant differences in mean maternal age, number of years of infertility before the pregnancy, history of previous pregnancies, amount of human menopausal gonadotropin used to induce ovulation, serum estradiol levels on the day of hCG administration, mean number of follicles, and the mean number of transferred embryos between the group who delivered and the group who aborted. We conclude that none of these factors are associated with increased tendency for fetal loss in our in vitro fertilization program. Beta-hCG levels on day 15 after embryo transfer were significantly lower in the group who aborted than in the group who delivered, and may be predictive of implantation failure.

摘要:
Bromocriptine and placebo were given to a group of 20 polycystic ovarian disease patients on a double-blind, crossover basis. Patients were studied for three cycles: a baseline cycle without any medication, a placebo-treated cycle, and a bromocriptine-treated cycle with multiple plasma samples taken during the different phases of the menstrual cycle. The clinical response to bromocriptine was compared with that of a placebo for the following hormones: prolactin (PRL), luteinizing hormone (LH)/follicle-stimulating hormone (FSH) ratio, testosterone, androstenedione, estradiol-17β(E2), estrone (El), and progesterone. Patients were divided into two subgroups: hyperprolactinemic (basal PRL greater than 20 ng/mL) and normoprolactinemic (basal PRL less than 20 ng/mL), and the response of both subgroups to bromocriptine was compared. Prolactin, LH/FSH ratio, testosterone, and El showed a significant drop with bromocriptine, whereas E2 significantly increased. Two out of nine amenorrheic polycystic ovarian disease patients menstruated during bromocriptine treatment, and three patients showed evidence of ovulation.

摘要:
To examine the effects of follicle-stimulating hormone (FSH) on cell proliferation and cell division in ovaries, deoxyribonucleic acid (DNA) polymerase activities and DNA concentrations were determined in ovarian follicles of immature, hypophysectomized, estradiol-treated rats perfused in vitro. Ovine FSH (2-20 μg/mL) significantly enhanced the DNA polymerase a activity in the follicles perfused for 180-300 minutes, whereas the DNA polymerase β activity and DNA concentration showed no significant changes. It is concluded that FSH causes the induction of DNA polymerase at before DNA synthesis during follicle growth in immature rat ovaries.

摘要:
To evaluate the efficacy of a single oral administration of the new ergot derivative Cabergoline in the prevention of postpartum lactation, we compared the effects of three different doses of the drug with those of placebo in 32 puerperal women. In a controlled, double-blind trial, the subjects were randomly allocated to four treatment groups receiving either placebo or 400, 600, or 800 ng Cabergoline (N=8 in each group) within 24 hours after delivery. Treatment efficacy was assessed clinically by physical examination before (day 0) and at one, two, three, four, and 14 days after treatment. Plasma prolactin (PRL) concentrations were measured in blood samples collected before and at one, two, three, and four days after treatment. Lactation was prevented in four of the eight subjects (50%) who received 400 μg Cabergoline and in all subjects who received 600 or 800 μg Cabergoline. By contrast, only one of the eight subjects (12.5%) receiving placebo showed no signs of spontaneous lactation within the 14 days after delivery. No effects of placebo administration on plasma PRL levels were observed. Plasma PRL concentrations were significantly reduced starting from one day after Cabergoline administration, however, and the amount of inhibition of PRL secretion induced by different doses of the drug was not statistically different. These preliminary data demonstrate that Cabergoline has a dose-related effect in the prevention of postpartum lactation, and milk secretion can be prevented completely by a single oral administration of 600 or 800 μg of the drug.

摘要:
One hundred seventy-five patients with features of ectopic pregnancy were studied, of whom 95 were subsequently shown to have an ectopic pregnancy. Paired blood and urine samples were assayed for human chorionic gonadotropin (hCG) by two radioimmunoassays, one immunoradiometric assay for intact hCG and an immunoradiometric assay for free beta subunit that also detects the “beta core” of hCG in urine. Qualitative testing was also performed using the Tandem Icon method of immunoconcentration on a membrane. The quantitative results for intact hCG showed an approximately unitary relationship between concentrations in both fluids, with a close correlation (r=0.84, gradient=1.01). The qualitative tests for hCG in both serum and urine were positive in all patients with ectopic pregnancy. The Tandem Icon is equally useful in blood and urine, whereas quantitative assays are more reliable in the blood. Quantitation of urinary hCG is not recommended because of the variable dilution of the glycoprotein in this fluid.

摘要:
The management of 540 patients with the diagnoses of “pelvic mass/uterine leiomyomata” was reviewed with respect to preoperative evaluation, surgical procedures, and final pathologic diagnosis. Approximately 6170 patients were admitted to the Gynecology Service at St. Luke's- Roosevelt Hospital Center from July 1984 to June 1985. During this period, 36 of 432 diagnostic laparoscopies (8.3%) and 503 of 1666 laparotomies (30.2%) were performed to evaluate or treat these women. The final diagnoses in the 249 patients admitted with the impression of leiomyomata were: leiomyomata, 235 (94.4%); benign adnexal masses, seven (2.8%); cancers, four (1.6%); and miscellaneous, three (1.2%). Of the 291 patients evaluated for pelvic mass, the findings were: benign ovarian or tubal cysts, 98 (33.7%); leiomyomata, 42 (14.4%); cancers, 40 (13.7%); benign cystic teratomas, 38 (13.1%); endometriosis, 28 (9.6%); miscellaneous, 23 (7.9%); and pelvic inflammatory disease, 22 (7.6%). Correlation between the patient's age, preoperative impression, and final diagnosis is presented with particular attention to the 44 patients (8.1%) in whom malignancy was found. All the possibilities that such masses may represent must be considered preoperatively, and the patient be informed of her risk of malignancy.

摘要:
Charts of 36 patients with clinical stage II endometrial adenocarcinoma over ten years were reviewed. All were staged before any treatment, in accordance with International Federation of Gynecology and Obstetrics (FIGO) guidelines. Although details of treatment varied, two main protocols were used. Fourteen patients were treated with the “standard” protocol involving external whole-pelvis radiation, followed by intracavitary cesium and then hysterectomy. In 1981, a “modified” protocol was introduced, which called for a hysterectomy immediately following intrauterine and vaginal cesium. External radiation therapy was given only to those patients found to have deep myometrial invasion or cervical involvement. Of 14 patients treated by this protocol, seven had no surgical indication for postoperative external radiation. There was no increase in recurrence in these patients, and the five-year survival rate was 76% for patients treated with the modified protocol compared with 65% for those who had standard therapy. Morbidity related to external radiation therapy occurred in two patients with the standard protocol and one patient who received pelvic radiation on the modified protocol.

摘要:
Twenty-seven advanced ovarian carcinoma patients who had received six courses of cyclophosphamide/cisplatin and had either microscopic disease (15 patients) or no pathologically detectable disease (12 patients) after second-look laparotomy were treated with abdominopelvic radiation (2250 cGy to the abdomen and pelvis and a 2250-cGy pelvic boost). Acute myelosuppression or gastrointestinal toxicity prevented completion of treatment in only three patients. However, bowel obstruction occurred in 13 (48%), ten of whom required surgery. Five of these ten had recurrent tumor, but the other five did not. Subsequently two of the latter five did develop a recurrence, one in the lung and one in the liver. A third patient died as an indirect result of radiation damage to the bowel. Median follow-up duration is 17 months from completion of radiation. So far, 13 (48%) have developed progressive disease: four (33%) of the 12 who had a negative second-look laparotomy and nine (60%) of the 15 who had microscopic disease before radiation. While acute toxicity is tolerable, the incidence of serious chronic bowel toxicity is high. Efforts should be made to alter this therapy in order to decrease the frequency of long-term morbidity.

摘要:
Between 1980-1985, 177 fine-needle aspirations were performed on 139 patients suspected of having recurrent gynecologic malignancy. Suspected sites of recurrence included a pelvic mass (122), peripheral lymph node (39), and a variety of other locations (16). There were 69 positives, 79 negatives, eight suspicious specimens, and 21 specimens inadequate for interpretation. Excluding suspicious or inadequate specimens, the results of the remaining 148 evaluable aspirations were confirmed by histopathologic correlation (35) or subsequent clinical course (113). Because there were no false positives, the specificity of the technique was 100%. The sensitivity was 68%, with an associated false-negative rate of 32%. The predictive value of a positive was 100%; that of a negative was 57%. An analysis of the false-negative results failed to show a correlation with cell type, lesion location, previous radiotherapy, or previous chemotherapy. The complication rate was less than 1%. These data support the conclusion that fine-needle aspiration cytology is a safe, highly specific method for diagnosing recurrent gynecologic malignancy. However, in patients with negative fine-needle aspiration cytology and suspected recurrent disease, it would appear that further evaluation is indicated.
