    To evaluate the efficacy of a single oral administration of the new ergot derivative Cabergoline in the prevention of post-partum 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 micrograms 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 micrograms Cabergoline and in all subjects who received 600 or 800 micrograms 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 micrograms of the drug

    The aim of this study was to determine the role of ultrasound evaluation of breast tissue, singularly and in a multivariate model, in the early differentiation between incomplete precocious puberty (IPP) and complete precocious puberty (CPP). In a retrospective analysis, we evaluated 52 girls (CPP in 26 cases and IPP in 26) aged 1.35 - 9.59 yrs (mean± SD 7.55±1.47 yrs). Diagnostic evaluation of pts included: breast Tanner stage, bone age, FSH and LH response to LHRH, basal 17-β-estradiol (E2), pelvic and breast ultrasound. Logistic regression models were fitted to identify possible diagnostic factors for IPP (as compared to CPP). All variables with a p-value<0.1 at univariate analysis were included in a multivariate model to assess their independent prognostic value. An additional model was fitted with mammal gland volume forced into the model, due to its clinical relevance. The area under the model ROC curve (AUC) was computed to assess model discrimination. The data indicate that in our pts uterine volume ≥ 5cc, LH peak ≥7UI/L and breast volume ≥ 1,1cc are hightly associated to CPP, bone age >2DS and E2 level ≥ 15μg/ml are only marginally associated, while FSH peak ≥10UI/L and diameter of the dominant follicle ≥ 1cm are not associated . Uterine volume, LH peak, bone age and diameter of the dominant follicle were included in a multivariate model, that showed an independent prognostic role of uterine volume and LH peak. The model had a high discriminant ability (AUC ROC 0.89) and permits to classify correctly 77.78% of cases. When adding breast volume to model, this also proved independent prognostic role for IPP, with further increase in discriminating ability (AUC ROC 0.91). This second model permits to classify correctly 82.22% of cases, so leading to better discrimination between IPP and CPP

    OBJECTIVE: to investigate the efficacy of a gonadotropin-releasing hormone analogue (GN-RH-a) in combination with human menopausal menotropin (hMG) for in-vitro fertilization. METHODS: 30 infertile women aged 32 to 37 years received a combined treatment with a long-acting slow-releasing Gn-RH-a and hMG to perform ovarian stimulation in a program of in-vitro fertilization. Serum levels of Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), 17-beta-estradiol (E2), Progesterone (P), were evaluated and transvaginal ultrasonographic examinations were performed during the treatment to assess the ovarian volume, the mean number and diameter of growing follicles and the endometrial morphology and thickness. Oocyte retrieval was performed by transvaginal-ultrasound-guided approach, 24-36 hours after the administration of human chorionic gonadotropin (hCG). RESULTS: our data suggest that the combined use of Gn-RH-a and exogenous gonadotropins is associated with a more uniform ovarian response and with the absence of premature LH discharge. Moreover, the Gn-RH-a as polymer implant provides a controlled delivery per day over a one-month period and avoids the inconvenience of a daily administration. CONCLUSIONS: this kind of Gn-RH-a formulation, in in-vitro fertilization programs, appears very effective in inducing a reversible hypogonadic state, easy to manage and well tolerated by the patient. Its association with exogenous gonadotropins appears to be effective in increasing the success rate of good quality oocyte retrieva
