Androgen therapy in women: for whom and when.

Androgens play a primary role in female physiopathology. The age-related reduction in the production of ovarian and adrenal androgens may significantly affect women's health. The decline of circulating androgens results from a combination of two events: reduced ovarian production and aged-related decline in adrenal androgen synthesis. The relative androgen deficiency in pre- and postmenopausal women may induce impairment of sexual function, libido, well-being, energy and may contribute to reduced cognitive functions. Whether androgen deficiency also affects cardiovascular or bone biology in women during reproductive aging is still controversial. Both in the central nervous system and peripheral tissues, there are multiple ways whereby androgens target their specific actions through a particular tropism of the brain areas that are involved in sexual function, behavior and cognition. Among circulating available androgens that are involved in several domains of sexual response, adrenal androgens seem to be related to some sexual symptoms as well as diminished cognitive function in postmenopausal women. The possibilities of treating low sexual desire/hypoactive sexual desire disorder are multifaceted and should include the combination of both pharmacological treatments able to maximize biological signals that drive the sexual response as well as individualized psychosocial therapies to overcome personal and relational difficulties. Transdermal testosterone has been proved to be effective but the use of additional treatment like oral or vaginal dehydroepiandrosterone is still controversial, despite many evidences support it. The decision to treat premenopausal or postmenopausal women with signs/symptoms of androgen insufficiency is mainly based on the clinical judgment, together with estrogens co-administration and following informed consent related to the unknown long-term risks.

Prenatal Environmental Stressors and DNA Methylation Levels in Placenta and Peripheral Tissues of Mothers and Neonates Evaluated by Applying Artificial Neural Networks.

Exposure to environmental stressors during pregnancy plays an important role in influencing subsequent susceptibility to certain chronic diseases through the modulation of epigenetic mechanisms, including DNA methylation. Our aim was to explore the connections between environmental exposures during gestation with DNA methylation of placental cells, maternal and neonatal buccal cells by applying artificial neural networks (ANNs). A total of 28 mother-infant pairs were enrolled. Data on gestational exposure to adverse environmental factors and on mother health status were collected through the administration of a questionnaire. DNA methylation analyses at both gene-specific and global level were analyzed in placentas, maternal and neonatal buccal cells. In the placenta, the concentrations of various metals and dioxins were also analyzed. Analysis of ANNs revealed that suboptimal birth weight is associated with placental H19 methylation, maternal stress during pregnancy with methylation levels of NR3C1 and BDNF in placentas and mother's buccal DNA, respectively, and exposure to air pollutants with maternal MGMT methylation. Associations were also observed between placental concentrations of lead, chromium, cadmium and mercury with methylation levels of OXTR in placentas, HSD11B2 in maternal buccal cells and placentas, MECP2 in neonatal buccal cells, and MTHFR in maternal buccal cells. Furthermore, dioxin concentrations were associated with placental RELN, neonatal HSD11B2 and maternal H19 gene methylation levels. Current results suggest that exposure of pregnant women to environmental stressors during pregnancy could induce aberrant methylation levels in genes linked to several pathways important for embryogenesis in both the placenta, potentially affecting foetal development, and in the peripheral tissues of mothers and infants, potentially providing peripheral biomarkers of environmental exposure.

Spontaneous cornual pregnancy after homolateral salpingectomy for an earlier tubal pregnancy: a case report and literature review.

Cornual pregnancy is an infrequent pathological condition with severe prognosis if not adequately recognized. Ipsilateral salpingectomy represents a unique risk factor for this clinical entity. This article reports a laparoscopically treated spontaneous cornual pregnancy after homolateral salpingectomy for an earlier tubal pregnancy in a condition of hemodynamic instability as a result of cornual rupture. We include a review of the literature, underlining the feasibility of a laparoscopic approach and new treatment options combining medical and surgical tools with specific attention to their impact on future fertility and on risk of uterine rupture in a future pregnancy.

Second-trimester diagnosis of intracranial vascular anomalies in a fetus with subdural hemorrhage.

OBJECTIVES: Risk factors for intracranial hemorrhage occurring in prenatal life are imperfectly known. A case of prenatal diagnosis of subdural hemorrhage associated with multiple intracranial vascular aneurysms is described. METHODS: Sonography and magnetic resonance imaging of the fetal head were obtained at 21 weeks' gestation and compared with pathologic findings. RESULTS: Sonography showed a large transonic mass displacing the normal intracranial structures. Magnetic resonance imaging demonstrated the hemorrhagic origin of the mass and showed multiple vascular anomalies. Postmortem examination confirmed the compression of the cerebral hemisphere by a blood collection, probably because of bleeding from one of the multiple vascular aneurysms into the subdural space. CONCLUSION: Magnetic resonance imaging with the use of single-shot ultrafast sequences may be useful not only in the differential diagnosis of fetal intracranial hemorrhage but also in identifying vascular risk factors.
