Heterotopic tubal pregnancy with a naturally conceived live twin intrauterine pregnancy in a patient with systemic lupus erythematosus: A case report.

Heterotopic pregnancy (HP) is defined as the simultaneous occurrence of an intrauterine and extrauterine gestation. Risk factors contributing to this condition are similar to those which contribute to ectopic pregnancy. While a triple heterotopic gestation through natural conception is uncommon, here we present the case of a patient with spontaneous intrauterine twins and a concurrent tubal extrauterine gestation, where the patient also had systemic lupus erythematosus.

TIMER: A Clinical Study of Energy Restriction in Women with Gestational Diabetes Mellitus.

Medical nutrition therapy is an integral part of gestational diabetes mellitus (GDM) management; however, the prescription of optimal energy intake is often a difficult task due to the limited available evidence. The present pilot, feasibility, parallel, open-label and non-randomized study aimed to evaluate the effect of a very low energy diet (VLED, 1600 kcal/day), or a low energy diet (LED, 1800 kcal/day), with or without personalized exercise sessions, among women with GDM in singleton pregnancies. A total of 43 women were allocated to one of four interventions at GDM diagnosis: (1) VLED ( = 15), (2) VLED + exercise ( = 4), (3) LED ( = 16) or (4) LED + exercise ( = 8).

Interplay Between mTOR and Hippo Signaling in the Ovary: Clinical Choice Guidance Between Different Gonadotropin Preparations for Better IVF.

One of the most widely used types of assisted reproduction technology is the fertilization (IVF), in which women undergo controlled ovarian stimulation through the administration of the appropriate hormones to produce as many mature follicles, as possible. The most common hormone combination is the co-administration of gonadotropin-releasing hormone (GnRH) analogues with recombinant or urinary-derived follicle-stimulating hormone (FSH). In the last few years, scientists have begun to explore the effect that different gonadotropin preparations have on granulosa cells' maturation and apoptosis, aiming to identify new predictive markers of oocyte quality and successful fertilization.

Physiology and Pathology of Contractility of the Myometrium.

Uterine atony is a serious obstetrical complication since it is the leading cause of postpartum hemorrhage. Postpartum hemorrhage (PPH) is one of the 5 major causes of postpartum mortality; therefore, it requires immediate medical intervention, independent of whether delivery occurs normally or with a cesarean section. While in the past years most cases of postpartum hemorrhage were caused due to uterine atony following vaginal delivery, in recent years most PPH cases indicate a significant association with cesarean delivery.

A Potential Pathogenic Link Between Cancer of Female Reproductive System and Infertile Women Treated With Assisted Reproduction Techniques.

Prevention and treatment of infertility remains a priority for developed countries where a large proportion of women undergo in vitro fertilization (IVF) after ovarian stimulation. Latest data suggest that, in the USA alone, almost eight million women of fertile age will have sought medical advice for fertility problems by 2025. However, over the last years, attention has been increasingly focused, and questions have risen, on the long-term health effects in women who underwent assisted reproductive technologies (ARTs).

Investigating the impact of different strategies for endometrial preparation in frozen cycles considering normal responders undergoing IVF/ICSI cycles: a multicenter retrospective cohort study.

Uncertainty exists concerning the type, adjunct, or dose of regimen to offer in frozen cycles in infertile women undergoing IVF/ICSI. Current systematic reviews have failed to identify one method of endometrial preparation as being more effective than another, whereas many IVF Units use variable and mixed protocols mainly based on their experience and convenience of use. Thus, we performed a four-center two-arm retrospective cohort study, encompassing 439 cycles in 311 women.

Primary Malignant Melanoma of the Cervix: A Case Report and a Review of the Literature.

Background: Gynecologic melanomas are extremely rare malignancies, and primary malignant melanoma of the cervix (PMMC) is the rarest among them all, with less than 100 cases reported so far. Although some conditions have been correlated with the pathogenesis of this entity, no specific risk factor has been yet identified, with vaginal bleeding being the most common symptoms. The diagnosis is based on physical examination with speculum assessment and cytologic and histopathologic findings accompanied with immunohistochemical staining of lesion's biopsies.

[Ambulatory and Home Blood Pressure Measurement in Hypertensive Pregnant Women].

The prevalence of hypertensive disorders in pregnancy (HDP) is 6-8%. Blood pressure measurement (BPM) remains the cornerstone of diagnosis and should be performed in a standardised manner using automated devices. Office BPM represents only a spotty reading in an "artificial" environment failing to diagnose white coat hypertension (WCH).
