Clinical, hormonal and sonographic predictors of successful RU-486-induced abortions.

To evaluate which method, clinical, hormonal or sonographic, can be used as the best predictor of successful RU-486-induced abortions, 20 healthy women with fetal cardiac activity, between 6 and 9 weeks from the last menstrual period and desiring abortion, were studied. Fourteen women (70%) successfully aborted, and 6 (30%) failed to abort within 7 days following therapy. A small hematoma, seen as a localized detachment of the gestational sac, was observed in the decidua capsularis in women who aborted successfully.

Acceptability and skin reactions to transdermal estrogen replacement therapy in relation to climate.

The acceptability and skin reaction of Estraderm Transdermal Therapeutic Systems as a function of climatic variability were examined in various zones which alter considerably in their temperature and humidity. An open, noncomparative prospective study was carried out in four institutional out-patient menopausal clinics in varying climatic areas. Eighty symptomatic postmenopausal patients without previous estrogen replacement were examined.

Neurologic involvement in hypertensive disease of pregnancy.

Neurologic manifestations of pregnancy-induced hypertension (PIH) vary from diffuse symptoms such as headache and confusion to focal signs such as paralysis and visual loss. Recognition of the neurologic symptoms associated with PIH is essential for early diagnosis of severe preeclampsia and eclampsia. The recent advances in neuroradiologic imaging, including the use of computed tomography (CT) scans and magnetic resonance imaging (MRI), have greatly enhanced our understanding of the correlation between neurologic complaints and neuroanatomic pathological changes characteristic of preeclampsia and eclampsia.

Renal and ocular manifestations of hypertensive diseases of pregnancy.

Hypertensive diseases of pregnancy are commonly manifested in renal and ocular changes. Proper evaluation of findings provided by urine analysis, renal biopsy and examination of the optic fundi, visual acuity, and visual fields may help in assessing the severity of the disease and the need for obstetric intervention. Furthermore, renal and ocular changes are important guides in the differential diagnosis of hypertensive disorders of pregnancy.

A simple scoring system for the treatment of cervical incompetence diagnosed during the second trimester.

Twenty-four women with second-trimester cervical incompetence underwent emergency cerclage. The appropriateness of cervical cerclage was analyzed according to a scoring system (Cervical Incompetence Scale; CIS) which measures the degree of cervical effacement, cervical dilatation and protrusion of fetal membranes into the cervical canal. Patients with low CIS (0-3 points) were found to have a more favorable pregnancy outcome than patients with high-score cervical incompetence (5-8 points), i.

Meteorological factors in hypertensive disorders, vaginal bleeding and premature rupture of membranes during pregnancy.

In order to determine whether there is a correlation between meteorological factors and the occurrence of hypertensive disorders, vaginal bleeding during pregnancy and premature rupture of the fetal membranes, we stratified all the patients hospitalized with such complications between the years 1984 and 1988 by the months of occurrence, weather, humidity and heat. During this period, there were 276 women hospitalized with exacerbation of hypertension and toxemia, 349 because of vaginal bleeding during pregnancy and 35 women following premature rupture of the fetal membrane between 30 and 33 weeks of gestation. The occurrence of pre-eclampsia and exacerbation of pregnancy-induced hypertension was significantly increased in the winter months (p less than 0.

Successful outcome of pregnancy following complete removal of uterine septum during cesarean section.

Two cases are described where a malformed uterus was the reason for either repeated abortions or premature deliveries resulting in fetal loss. In both cases the removal of the septum during cesarean section resulted in uneventful postoperative courses, and subsequently in successful pregnancies and births of healthy infants to both women.

Human fetal behavioral state at term.

The present study was designed to test the existence of behavioral states in the fetus at term using simplified techniques. For this purpose simultaneous recording of the fetal heart activity by means of phonocardiotocography and of fetal body movements by means of real-time ultrasound was performed by using a multichannel recorded. The fetal heart activity was analyzed for two parameters: (1) long-term variability and (2) baseline accelerations.

Immunization by paternal leukocytes for prevention of primary habitual abortion: results of a matched controlled trial.

Habitual abortion is a difficult clinical problem, as no cause can be found for abortion in over 50% of patients. At the habitual abortion clinic of the Sheba Medical Center, immunological activity is tested and patients who are considered suitable are offered immunopotentiation with paternal leukocytes. Patients are only treated if they have no other cause for habitual abortion, no lupus anticoagulant and no antipaternal complement-dependent antibodies (APCA).

Breast stimulation in late pregnancy. Effect on prostaglandin secretion.

The effect of breast stimulation on the prostaglandin secretion was tested in 13 patients at 38-40 weeks of gestation. Uterine contractions following breast stimulation were documented in all cases. There was an increase in prostaglandin metabolite levels 10 min after breast stimulation.

Fetal habituation to sound stimulus in various behavioral states.

The correlation between arousal state and fetal habituation was tested. Four behavioral states were determined according to fetal heart activity and movement pattern in 52 fetuses. Repeated wide low-frequency sound was used as external stimulus.

The association of pregnancy-induced hypertension and uterine malformations.

To evaluate the incidence of pregnancy-induced hypertension (PIH) in women with congenital uterine malformations, we examined the pregnancy complications of 67 women with uterine anomalies demonstrated by hysterosalpingography (HSG). The study group was compared with a control group of 130 women with normal-shaped uterus proven by HSG-matched for age, parity and presenting complaint. A significantly increased (p less than 0.

In vitro fertilization in Kock's ileostomy patients. Prior evaluation by pelvic ultrasonography.

The study describes Kock's continent ileostomy in 2 females, both of whom were suffering from tubal infertility. Appropriate placement of the abdominal pouch, permitting in vitro fertilization embryo transfer treatment, was present in 1 patient. In the other patient, an ultrasonographic examination demonstrated the pouch covering the entire surface area of both ovaries.

Selection of patients with habitual abortion for paternal leucocyte immunization.

After potentiation of the immune response in habitual aborters 75-85% of subsequent pregnancies are claimed to result in healthy term infants. However, all publications to date have either been based on the authors concept of the immune processes involved or an attempt to demonstrate the efficacy of treatment either empirically or by matched trials. As immunization is coming into wider clinical use, it is necessary to determine which patients will benefit from this form of treatment.

Beta-endorphin levels in the follicular fluid of human oocytes fertilized in vitro.

This study was carried out in order to investigate the relationship between beta-endorphin (beta-ep) levels in plasma and follicular fluid and fertilization rates of oocytes from women undergoing treatment in our in vitro fertilization and embryo transfer program. Nine women suffering from severe tubal damage, with regular menstrual cycles, were studied. Follicular growth was induced with clomiphene citrate, combined with human menopausal gonadotropins.

Failure to improve ovarian response by combined gonadotropin-releasing hormone agonist and gonadotropin therapy.

Nineteen women were treated with the gonadotropin-releasing hormone (GnRH) agonist buserelin in order to suppress the pituitary prior to gonadotropin treatment. Eight women were oligomenorrheic, 6 had polycystic ovarian disease (PCOD) and 5 women had normal cycles. Buserelin was administered for 3 weeks before ovarian stimulation, and the pituitary down-regulation was proven by provocative tests.

The improving outcome of triplet pregnancies.

During the period 1975 to 1988, 78 triplet pregnancies that reached a gestational age greater than or equal to 20 weeks were treated in our department--a prevalence of 1/849 deliveries. A total of 69 (88%) of the pregnancies occurred after treatment with ovulation-induction agents. The most common complication of pregnancy was premature contractions.

Hot flushes during Gn-RH analogue administration despite normal serum oestradiol levels.

Five out of 6 normally-menstruating women who were treated with a potent gonadotropin-releasing hormone (Gn-RH) agonist in order to achieve medical hypophysectomy developed hot flushes despite having normal oestradiol (E2) levels. The Gn-RH agonist was administered subcutaneously for 6 days and then intranasally for a further 14 days. A dose of 2 mg of E2 benzoate was injected intramuscularly once a week for 2 consecutive weeks.

The role of gonadotropins in the etiology of ectopic pregnancy.

Our study indicates that the high rate of EP in MAP(+) patients, treated with hMG/hCG, is due to the fact that it is a selected group of infertile patients with probable additional underlying tubal disease. Absence of EP in MAP(-) patients indirectly support the theory that a mechanical factor is at work. It is, therefore, our opinion, that the cause of ectopic pregnancy lies in the patient and not in the drug (hMG/hCG).

Endocrinological basis of hot flushes.

Hot flushes are frequent among women during natural, surgical, or pharmacological menopause. The available data suggest the involvement of estrogens, progestins, catecholestrogens, catecholamines, dopamine, endorphins, prostaglandins, luteinizing hormone (LH) and luteinizing hormone-releasing hormone (LH-RH) in the pathogenesis of flushes. At present the estrogen withdrawal and pulsatile luteinizing hormone (LH) secretion theories are most commonly accepted for explaining the development of this symptom.

Fetal motorical and heart response to sound stimulus in different behavioral states.

In 32 fetuses from 37 to 41 weeks' gestation, motorical and heart rate response time, as well as the influence of arousal state on that time were tested. Motorical response time was defined as the time from external stimulus to fetal movement. Heart rate response time was defined as the time from stimulus to the increase in baseline of 15 beats/min.

Transcervical chorionic villi sampling: a comparison between the silver cannula and the Portex catheter.

The Portex catheter and the silver cannula are two of the most widely used biopsy devices for chorionic villus sampling. In a prospective randomized study we used these two devices alternatively in 168 women. Significantly more trophoblastic tissue was obtained with the silver cannula than with the Portex catheter (p less than 0.
