Criteria, prevalence, and phenotypes of polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a highly prevalent disorder effecting reproductive-aged women worldwide. This article addresses the evolution of the criteria used to diagnosis PCOS; reviews recent advances in the phenotypic approach, specifically in the context of the extended Rotterdam criteria; discusses limitations of the current criteria used to diagnosis, particularly when studying adolescents and women in the peri- and postmenopause; and describes significant strides made in understanding the epidemiology of PCOS. This review recognizes that although there is a high prevalence of PCOS, there is increased variability when using Rotterdam 2003 criteria, owing to limitations in population sampling and approaches used to define PCOS phenotypes. Last, we discuss the distribution of PCOS phenotypes, their morbidity, and the role that referral bias plays in the epidemiology of this syndrome.

Identification of Polycomb Group Protein EZH2-Mediated DNA Mismatch Repair Gene MSH2 in Human Uterine Fibroids.

Uterine fibroids (UFs) are benign smooth muscle neoplasms affecting up to 70% of reproductive age women. Treatment of symptomatic UFs places a significant economic burden on the US health-care system. Several specific genetic abnormalities have been described as etiologic factors of UFs, suggesting that a low DNA damage repair capacity may be involved in the formation of UF. In this study, we used human fibroid and adjacent myometrial tissues, as well as an in vitro cell culture model, to evaluate the expression of MutS homolog 2 (MSH2), which encodes a protein belongs to the mismatch repair system. In addition, we deciphered the mechanism by which polycomb repressive complex 2 protein, EZH2, deregulates MSH2 in UFs. The RNA expression analysis demonstrated the deregulation of MSH2 expression in UF tissues in comparison to its adjacent myometrium. Notably, protein levels of MSH2 were upregulated in 90% of fibroid tissues (9 of 10) as compared to matched adjacent myometrial tissues. Human fibroid primary cells treated with 3-deazaneplanocin A (DZNep), chemical inhibitor of EZH2, exhibited a significant increase in MSH2 expression (P < .05). Overexpression of EZH2 using an adenoviral vector approach significantly downregulated the expression of MSH2 (P < .05). Chromatin immunoprecipitation assay demonstrated that enrichment of H3K27me3 in promoter regions of MSH2 was significantly decreased in DZNep-treated fibroid cells as compared to vehicle control. These data suggest that EZH2-H3K27me3 regulatory mechanism dynamically changes the expression levels of DNA mismatch repair gene MSH2, through epigenetic mark H3K27me3. MSH2 may be considered as a marker for early detection of UFs.

Vitamin D and Female Reproduction

Vitamin D deficiency has an impact on the reproduction of more than 40% of repro‐ ductive age women globally. Fibroids are more common among African‐American females owing to their decreased milk consumption and reduced absorption of ultraviolet rays, supporting the relation between vitamin D deficiency and fibroid development. Vitamin D has an inhibitory effect on leiomyoma cells by suppression of proliferation cell nuclear antigen (PCNA), BCL‐2, BCL‐w, CDK1, and catechol‐O‐ methyltransferase (COMT) protein levels. A growing evidence support the relationship between vitamin D deficiency and endometriosis through overexpression of vitamin D recseptor (VDR) and α‐hydroxylase enzyme, however, it is still unclear if the endome‐ triosis patients could benefit from vitamin D supplementation. Effect of vitamin D supplementation on the metabolic outcomes of polycystic ovary (PCO) has been studied and reveled that it is negatively correlated with fasting glucose, fasting insulin, triglycerides, C‐reactive protein, free androgen index, and Dehydroepiandrosterone (DHEAS) and positively associated with quantitative insulin sensitivity check index (QUICKI), high density lipoprotein cholesterol (HDL‐C), and sexual hormone binding globulin (SHBG), whereas its impact on the ovarian function is still unclear. Vitamin D deficiency may worse the obstetrical outcomes, including preeclampsia, gestational diabetes, low birth weight, increased cesarean section rate, neonatal asthma, seizures, and preterm labor. The relationship between serum levels of 25‐hydroxy‐vitamin D (25(OH) D) and pregnancy rates in ART is still debatable, with the need to conduct more clinical trials toward it. The in vitro antiproliferative and prodifferentiative effect of vitamin D might find a role in control of hyperplastic overactive bladder. Several studies support that vitamin D deficiency constitutes a risk factor for development of many types of cancer such as breast, ovarian, and colorectal.

A modern radiologic treatment for pelvic congestion syndrome associated with chronic pelvic pain and menstrual abnormalities

Introduction With greater than one-tenth of outpatient gynecology visits attributed to chronic pelvic pain, research into etiology and management of the spectra of chronic pain disorders is very important. One such etiology, pelvic congestion syndrome (PCS), is a disease in which pelvic varicosities are present as a result of dysfunctional venous valves, retrograde blood flow, venous hypertension, and dilation. The presence of these varicosities, which exist in up to 10% of women between 18 and 76 years of age, can be detected by various imaging techniques including ultrasound, contrasted computed tomography, and magnetic resonance imaging. Various treatment methodologies have been described for the management of this chronic pain disorder, including medical, endovascular, and surgical therapies. With advancements in imaging, and the opportunity for endovascular intervention via interventional radiology, minimally invasive left ovarian vein embolization is at the forefront of therapeutic efforts for this nefarious condition. Methods We present here our clinical experience of 9 patients with PCS who underwent left ovarian vein embolization using a standardized protocol. Results Subjective pain relief was noted in 8 of 9 patients; 7 of the 9 patients reported complete resolution of pain at the 4-week follow-up, and associated symptoms similarly resolved. Conclusions Any thorough evaluation of a patient with chronic pelvic pain should include an evaluation for PCS when the diagnosis is not immediately available. Increased physician awareness of PCS is imperative for the future. With these astounding results, we recommend an excellent option for treatment of patients with left ovarian vein embolization.

A decade of pelvic pain and infertility: a case report of an unexpected intraoperative discovery

Introduction Retained surgical objects can impact quality of life as it relates to chronic pelvic pain and reproductive health. Case report A 39-year-old G1P0010 with chronic pelvic pain and infertility attributed to pelvic adhesions and bilateral hydrosalpinx caused by an 18-cm surgical drain left 10 years prior. Conclusions Our case highlights the significance of thoughtful perioperative care as well as special considerations when approaching patients with pelvic pain and infertility with histories of abdominopelvic surgery.
