Pelvic floor muscle training for prevention and treatment of urinary incontinence during pregnancy and after childbirth and its effect on urinary system and supportive structures assessed by objective measurement techniques.

PURPOSE: During the second and the third trimesters of pregnancy and in the first 3 months following childbirth, about one-third of women experience urinary incontinence (UI). During pregnancy and after delivery, the strength of the pelvic floor muscles may decrease following hormonal and anatomical changes, facilitating musculoskeletal alterations that could lead to UI. Pelvic floor muscle training (PFMT) consists in the repetition of one or more sets of voluntary contractions of the pelvic muscles. By building muscles volume, PFMT elevates the pelvic floor and the pelvic organs, closes the levator hiatus, reduces pubovisceral length and elevates the resting position of the bladder. Objective of this review is to evaluate the efficacy of PFMT for prevention and treatment of UI during pregnancy and after childbirth and its effect on urinary system and supportive structures assessed by objective measurement techniques. METHODS: The largest medical information databases (Medline-Pubmed, EMBASE, Lilacs, Cochrane Library and Physiotherapy Evidence Database) were searched using the medical subject heading terms "pelvic floor muscle training", "prevention", "urinary incontinence", "urinary stress incontinence", "objective measurement techniques", "pregnancy, "exercise", "postpartum" and "childbirth" in different combinations. RESULTS AND CONCLUSIONS: Overall, the quality of the studies was low. At the present time, there is insufficient evidence to state that PFMT is effective in preventing and treating UI during pregnancy and in the postpartum. However, based on the evidence provided by studies with large sample size, well-defined training protocols, high adherence rates and close follow-up, a PFMT program following general strength-training principles can be recommended both during pregnancy and in the postnatal period.

Radiations and female fertility.

Hundreds of thousands of young women are diagnosed with cancer each year, and due to recent advances in screening programs, diagnostic methods and treatment options, survival rates have significantly improved. Radiation therapy plays an important role in cancer treatment and in some cases it constitutes the first therapy proposed to the patient. However, ionizing radiations have a gonadotoxic action with long-term effects that include ovarian insufficiency, pubertal arrest and subsequent infertility. Cranial irradiation may lead to disruption of the hypothalamic-pituitary-gonadal axis, with consequent dysregulation of the normal hormonal secretion. The uterus might be damaged by radiotherapy, as well. In fact, exposure to radiation during childhood leads to altered uterine vascularization, decreased uterine volume and elasticity, myometrial fibrosis and necrosis, endometrial atrophy and insufficiency. As radiations have a relevant impact on reproductive potential, fertility preservation procedures should be carried out before and/or during anticancer treatments. Fertility preservation strategies have been employed for some years now and have recently been diversified thanks to advances in reproductive biology. Aim of this paper is to give an overview of the various effects of radiotherapy on female reproductive function and to describe the current fertility preservation options.

Maternal exposure to endocrine disruptors and placental transmission: a pilot study.

Endocrine disruptors (EDs) are known to affect maternal and child health. The objective of our study was to identify the association between some of the most important endocrine-disruptive substances (perfluorooctane sulfonate [PFOS], perfluorooctanoic acid [PFOA], di2-ethylhexyl-phthalate [DEHP] and mono2-ethylhexyl-phthalate [MEHP]) and both pregnancy variability and birth outcomes. We measured the concentration of the EDs in maternal and cord blood samples of 29 mother-newborn pairs from the Pertini Hospital in Rome between March and June 2016. Each mother reported demographic, life style and diet information. We compared concentrations of the endocrine disruptors between mother and newborn, and among different molecules. We analyzed differences and trends of each ED substance according to the demography and diet information. PFOA levels in maternal blood showed a negative association with newborn weight. Concentration levels of PFOA in both maternal and cord blood of those with physiological progression of pregnancy were higher in than in those with pathological pregnancies. MEHP trend showed a positive association with maternal age. These results confirm the maternal-to-fetus transfer of EDs through the placenta and the impact that endocrine disruptors have on pregnancy and birth outcomes.

Myoma and myomectomy: Poor evidence concern in pregnancy.

AIM: Summarize the results of the many, but often underpowered, studies on pregnancy complicated by myoma or myomectomy. METHODS: Survey of the electronic PubMed database for the last two decades was conducted. We selected reviews, meta-analyses, case series, case reports, clinical studies only with statistical analysis, and guidelines from scientific societies. RESULTS: Delaying childbearing leads to an increased incidence of pregnancy complicated by fibroids or previous myomectomy. Approximately 10-30% of pregnant women with myomas develop complications during gestation, at delivery and in puerperium. Submucosal, retroplacental, large and multiple myomas have a greater risk of complications. Cervical myomas, although rare, need careful management. The location and size of the fibroids should be assessed from the first trimester. Despite the increased risk of cesarean section, fibroids are not a contraindication to labor, unless they obstruct the birth canal or other obstetric conditions coexist. Myomectomy during pregnancy, in selected cases, is feasible and safe. Myomectomy cannot be considered a prophylactic measure prior to conception, but has to be individualized. Uterine rupture after myomectomy generally occurs in the third trimester or during labor and some associated risk factors have been identified. There is no consensus on the optimal interval between myomectomy and conception. CONCLUSIONS: Pregnancy in patients with fibroids or previous myomectomy should be considered as high risk, requiring a maternal-fetal medicine specialist. To date available literature is inconsistent on evidence-based management. Further research is needed for definitive recommendations.

Endocrine Disrupting Chemicals and Endometrial Cancer: An Overview of Recent Laboratory Evidence and Epidemiological Studies.

Background: Although exposure to endocrine disruptor compounds (EDCs) has been suggested as a contributing factor to a range of women's health disorders including infertility, polycystic ovaries and the early onset of puberty, considerable challenges remain in attributing cause and effect on gynaecological cancer. Until recently, there were relatively few epidemiological studies examining the relationship between EDCs and endometrial cancer, however, in the last years the number of these studies has increased. Methods: A systematic MEDLINE (PubMed) search was performed and relevant articles published in the last 23 years (from 1992 to 2016) were selected. Results: Human studies and animal experiments are confirming a carcinogenic effect due to the EDC exposure and its carcinogenesis process result to be complex, multifactorial and long standing, thus, it is extremely difficult to obtain the epidemiological proof of a carcinogenic effect of EDCs for the high number of confusing factors. Conclusions: The carcinogenic effects of endocrine disruptors are plausible, although additional studies are needed to clarify their mechanisms and responsible entities. Neverthless, to reduce endocrine disruptors (ED) exposure is mandatory to implement necessary measures to limit exposure, particularly during those periods of life most vulnerable to the impact of oncogenic environmental causes, such as embryonic period and puberty.

The effect of maternal exposure to endocrine disrupting chemicals on fetal and neonatal development: A review on the major concerns.

There is a widespread exposure of general population, including pregnant women and developing fetuses, to the endocrine disrupting chemicals (EDCs). These chemicals have been reported to be present in urine, blood serum, breast milk, and amniotic fluid. Endocrine disruptions induced by environmental toxicants have placed a heavy burden on society, since environmental exposures during critical periods of development can permanently reprogram normal physiological responses, thereby increasing susceptibility to disease later in life-a process known as developmental reprogramming. During development, organogenesis and tissue differentiation occur through a continuous series of tightly-regulated and precisely-timed molecular, biochemical, and cellular events. Humans may encounter EDCs daily and during all stages of life, from conception and fetal development through adulthood and senescence. Nevertheless, prenatal and early postnatal windows are the most critical for proper development, due to rapid changes in system growth. Although there are still gaps in our knowledge, currently available data support the urgent need for health and environmental policies aimed at protecting the public and, in particular, the developing fetus and women of reproductive age.

Bisphenol A and the female reproductive tract: an overview of recent laboratory evidence and epidemiological studies.

Bisphenol A (BPA) is a high production volume monomer used for making a wide variety of polycarbonate plastics and resins. A large body of evidence links BPA to endocrine disruption in laboratory animals, and a growing number of epidemiological studies support a link with health disorders in humans. The aim of this review is to summarize the recent experimental studies describing the effects and mechanisms of BPA on the female genital tract and to compare them to the current knowledge regarding the impact of BPA impact on female reproductive health. In particular, BPA has been correlated with alterations in hypothalamic-pituitary hormonal production, reduced oocyte quality due to perinatal and adulthood exposure, defective uterine receptivity and the pathogenesis of polycystic ovary syndrome. Researchers have reported conflicting results regarding the effect of BPA on premature puberty and endometriosis development. Experimental studies suggest that BPA's mechanism of action is related to life stage and that its effect on the female reproductive system may involve agonism with estrogen nuclear receptors as well as other mechanisms (steroid biosynthesis inhibition). Notwithstanding uncertainties and knowledge gaps, the available evidence should be seen as a sufficient grounds to take precautionary actions against excess exposure to BPA.

Pregnancy in a unicornuate uterus: a case report.

INTRODUCTION: A unicornuate uterus accounts for 2.4 to 13% of all Müllerian anomalies. A unicornuate uterus with a non-communicating rudimentary horn may be associated with gynecological and obstetric complications such as infertility, endometriosis, hematometra, urinary tract anomalies, abortions, and preterm deliveries. It has a poor reproductive outcome and pregnancy management is still unclear. CASE PRESENTATION: We report a case of a 26-year-old Caucasian woman presenting with a unicornuate uterus with a non-communicating rudimentary horn. The diagnosis of the anomaly was based on two-dimensional and three-dimensional sonography. The excision of her symptomatic rudimentary horn and her ipsilateral fallopian tube was performed laparoscopically. The growth of the fetus was normal. At 20 weeks' pregnancy, her cervix started shortening and a tocolytic therapy was started. A cesarean delivery was successfully performed at 39 weeks and 4 days' gestation. CONCLUSIONS: Although the reproductive outcome of women with unicornuate uterus is poor, a successful pregnancy is possible. Routine excision of the rudimentary horn should be undertaken during non-pregnant state laparoscopically, and it would be necessary to screen such pregnancies for the development of intrauterine growth retardation with serial ultrasound assessments of the estimated fetal weight and the cervix length.

The influence of cigarette smoking on a population of infertile men and women.

PURPOSE: This study aimed at investigating the effect of cigarette smoking on semen parameters in infertile men and on antral follicle count (AFC) and reproductive hormone levels in infertile women. METHODS: In 648 men (200 smokers and 448 non-smokers) sperm concentration, motility and morphology were compared according to smoking status. In the female population, AFC and basal follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol were measured in 296 women (102 smokers and 194 non-smokers). Statistical analysis of data was performed using t test, χ²-test and Spearman's correlation. RESULTS: Among the male population, smokers had significantly lower sperm concentration and motility than non-smokers. Sperm normal morphology was reduced in smokers, although this difference did not reach statistical significance. No significant correlation was found between sperm parameters and the intensity of smoking. In the female population, AFC was reduced in smokers compared with non-smokers. Women who smoked had significantly higher FSH levels. No significant difference was found in LH and estradiol levels according to smoking status. The number of pack-years was negatively correlated to AFC and positively correlated to FSH levels. CONCLUSION: Cigarette smoking is associated with damaging effects on sperm parameters in infertile men and with ovarian reserve alteration in infertile women, as reflected by reduced AFC and increased FSH levels. Every smoker should be encouraged to stop smoking to prevent the damage of the toxins contained in cigarette smoking and preserve their own reproductive potential.
