Endometrial transformations achieved by vaginal progesterone exceed those normally expected from the circulating concentrations obtained, this suggests some degree of direct vagina to uterus transport. We speculate on the different mechanisms involved in uterine specificity of vaginal progesterone and report data of a preliminary randomized study comparing progesterone concentrations in serum and endometrial tissue obtained from hysterectomy specimens after vaginal or i.m. administration. Eight post-menopausal women undergoing transabdominal hysterectomy were randomized to receive either vaginal progesterone gel, 90 mg, or i.m. progesterone formulation, 50 mg, at 08.00 and 20.00 on the day before surgery and at 06.00 on the day of surgery. Venous blood samples for progesterone measurement were drawn at 08.00 on the day before surgery and during the surgery. Endometrial progesterone concentrations were markedly higher in women who received vaginal progesterone (1.38+/-0.66 and 0.38+/-0.19 ng/mg protein, for vaginal and i.m. groups respectively) (P < 0.02) despite lower serum concentrations (4.17 < 0.56 and 32.32+/-11.06 ng/ml, for vaginal and i.m. groups respectively) (P < 0.001). The vaginal route induces endometrial progesterone concentrations that far exceed those expected from the serum progesterone concentrations achieved. 相似文献

We report on a patient with left hemiparesis and peripersonal neglect after post-traumatic left frontal hemorrhage, who underwent fMRI, TMS and TCD to identify the functional abnormalities that account for his neurological symptoms, in the absence of any detectable lesion affecting right motor areas. 相似文献

The study of SARS-CoV-2 positive pregnant women is of some importance for gynecologists, obstetricians, neonatologists and women themselves. In recent months, new works have tried to clarify what happens at the fetal–placental level in women positive for the virus, and different pathogenesis mechanisms have been proposed. Here, we present the results of a large series of placentas of Coronavirus disease (COVID) positive women, in a reference center for COVID-positive pregnancies, on which we conducted histological, immunohistochemical and electron microscopy investigations. A case–control study was conducted in order to highlight any histopathological alterations attributable to SARS-CoV-2. The prevalence of maternal vascular malperfusion was not significantly different between cases and controls (54.3% vs. 43.7% p = 0.19), whereas the differences with regard to fetal vascular malperfusion (21.1% vs. 4.2% p < 0.001) were significant. More frequent in cases with respect to controls were decidual arteriopathy (40.9% vs. 1.4% p < 0.0001), decidual inflammation (32.4% vs. 0.7% p < 0.0001), perivillous fibrin deposition (36.6% vs. 3.5% p < 0.0001) and fetal vessel thrombi (22.5% vs. 0.7% p < 0.0001). No significant differences in the percentage of terminal villous hyperplasia and chorioamnionitis were observed between the two groups. As the pandemic continues, these studies will become more urgent in order to clarify the possible mechanism of maternal–fetal transmission of the virus. 相似文献

The bioavailability and the clinical usefulness of the P administered by nasal spray were investigated. Ten healthy menopausal women received an IN spray administration (4 doses of an oleic P solution 20 mg/mL, corresponding to nearly 11.2 mg of P) and the circulating P levels were calculated. Sixty minutes after administration, the maximum concentration (CMax, 3.75 +/- 0.214 ng/mL) was reached. High P levels (greater than 2 ng/mL) lasted until 360 minutes, and the AUC 0 to 720 was 1,481.6 +/- 343 ng.h/mL. Progesterone administration by spray formulation has proven to be effective in reaching therapeutic levels and to be acceptable to patients and, probably, clinically safe. 相似文献

In a prospective randomized study 38 women with idiopathic hirsutism or polycystic ovary syndrome (PCOS) received 2.5 mg of finasteride every day or every 3 days. Intermittent low-dose administration of finasteride was as effective as continuous administration in reducing hirsutism score and was accompanied by a lower incidence of side effects. 相似文献

This study was designed to evaluate the effectiveness and clinical usefulness of the hypo-osmotic swelling (HOS) test in predicting successful conception in couples in which men with mild male-factor infertility criteria were undergoing a timed vaginal inter-course protocol. One hundred couples, in which mild male infertility was the only abnormality, were included in the study. Semen was analyzed according to standard World Health Organization (WHO) criteria and subjected to the HOS test. Patients were divided into 2 groups: group 1 (n=39) with normal HOS test and group 2 (n=61) with abnormal HOS test. All women underwent three consecutive cycles of follicular growth ultrasound monitoring and timed intercourse. Ten couples were exclude from the study. Ten clinical pregnancies were achieved in group 1 with a pregnancy rate per patient and per cycle of 28.5% and 9.5%, respectively. In group 2, 6 pregnancies were achieved, with a pregnancy rate per patient and per cycle of 10.9% and 3.6%, respectively. Both pregnancy rates per patients and per cycle was significantly higher (P <.05) in group 1 than in group 2. The HOS test may be considered an easy and reliable test in identifying among subfertile men those who have a greater possibility of causing pregnancy. 相似文献
