: Abstracts Background: Implantation failure of in vitro fertilization (IVF) cycles is recognized as one of key problems in contemporary reproductive medicine. Implantation itself is a multifactorial process and one can hardly expect to find a single criterion for the endometrium receptivity. Endometrium biopsy still remains the most applicable technique to diagnose abnormalities causing decrease or complete loss of endometrial receptivity. MATERIALS AND METHODS: We have studied 95 endometrial biopsy samples from 45 patient with I/II stage endometriosis and 40 controls from October 2014 to December 2015...

Endometriosis is a chronic, progressive, relapsing estrogen-dependent disorder characterized by the growth of tissue structure and function similar to the endometrium outside the normal mucosa of the uterine cavity localization. Endometriosis is found in 10-15% of women in reproductive age and it is one of the main causes of pelvic pain syndrome and infertility. Mechanisms of the development of endometriosis and related pathological pain impulses are still poorly understood and therapeutic approaches do not always have a sufficient effect; in this connection, the study of the pathogenesis of endometriosis and endometriosis-associated pain currently is perspective...

Endometriosis is a gynecologic disease affecting up to 10% of the women and a major cause of pain and infertility. It is characterized by the implantation of functional endometrial tissue at ectopic positions generally within the peritoneum. This complex disease has an important genetic component with a heritability estimated at around 50%. This review aims at providing recent insights into the genetic bases of endometriosis, and present a detailed overview of evidence of epigenetic alterations specific to this disease...

BACKGROUND: The potential association between endometriosis and physical activity (PA) has been suggested in several epidemiological studies.We aimed to establish whether PA influences endometriosis risk. METHODS: MEDLINE and EMBASE were searched using "physical activity" OR "exercise" combined with "endometriosis," in Medical Subject Headings and free text. We selected original articles in English, published up to April 2016, evaluating the association between endometriosis and recent or past PA (case-control or cohort studies)...

Endometriosis is defined as the presence of endometrial glands and stroma outside the uterus. It affects 3 to 10 percent of women of reproductive age. Umbilical endometriosis is rare, with an estimated incidence of 0.5-1.0% among all cases of endometriosis, and is usually secondary to prior laparoscopic surgery involving the umbilicus. In this report, we described a case of umbilical endometriosis treated with surgical resection and highlight the great importance of medical history compared to complementary diagnostic tests that can be sometimes inconclusive...

Endometriosis affects 5-10% of women in reproductive age, leading to dysmenorrhea, pelvic pain and infertility; however, our understanding on the pathogenesis of this disease remains incomplete. In the present study, we performed a systematic analysis of endometriosis-related genes using text mining. Taking text mining results as input, we subsequently generated a filtered gene set by computing the likelihood of finding more than expected occurrences for every gene across the disease-centered subset of the PubMed database...

OBJECTIVES: To investigate the prognostic value of endometriosis in patients with stage I ovarian clear cell carcinoma (OCCC). METHODS: The medical records of patients with stage I OCCC who had undergone complete staging surgery followed by systemic chemotherapy were retrospectively reviewed. RESULTS: A total of 237 women were included in this study. Univariate analysis revealed that the patients with endometriosis-associated ovarian carcinoma (EAOC) had significantly improved recurrence-free survival (RFS) and overall survival (OS) than those without EAOC (5-year RFS: 91...

BACKGROUND Endometriosis can cause dysmenorrhea and infertility. Its pathogenesis has not yet been clarified and its treatment continues to pose enormous challenges. The protein tyrosine phosphatase (PTEN) gene is a tumor suppressor gene. The aim of this study was to investigate the role and significance of PTEN protein in the occurrence, development, and treatment of endometriosis through changes in apoptosis rate, cell cycle, and angiogenesis. MATERIAL AND METHODS PTEN was overexpressed and silenced in lentiviral vectors and inserted into primary endometrial cells...

STUDY OBJECTIVE: Young age is a possible risk factor of endometriosis recurrence after surgery. However, the efficacy of postoperative medical treatment has not been well addressed in adolescents. The purpose of this study was to evaluate whether postoperative medical treatment is as effective in adolescents as it is in adults in the prevention of endometrioma recurrence. DESIGN: A retrospective cohort study SETTING: Samsung Medical Center, Seoul, Korea. PARTICIPANTS: This study included 176 reproductive-aged women who underwent conservative laparoscopic surgery for pathology-confirmed endometrioma...

Aberrant miRNA expression has been reported in endometriosis and miRNA gene polymorphisms have been linked to cancer. Because certain ovarian cancers arise from endometriosis, we genotyped seven cancer-related miRNA single nucleotide polymorphisms (MiRSNPs) to investigate their possible roles in endometriosis. Genetic variants in MIR196A2 (rs11614913) and MIR100 (rs1834306) were found to be associated with endometriosis development and related clinical phenotypes, such as infertility and pain. Downstream analysis of the MIR196A2 risk allele revealed upregulation of rRNA editing and protein synthesis genes, suggesting hyper-activation of ribosome biogenesis as a driving force for endometriosis progression...

Endometriosis is a complex, inflammatory disease that affects 6-10% of reproductive-aged women. Almost half of the women with endometriosis experience infertility. Despite the excessive prevalence, the pathogenesis of endometriosis and its associated infertility is unknown and a cure is not available. While many theories have been suggested to link endometriosis and infertility, a consensus among investigators has not emerged. In this extensive review of the literature as well as research from our laboratory, we provide potential insights into the role of immune dysfunction in endometriosis associated infertility...

This correlational study investigated the relationships between temperament, beliefs about pain control, and pain intensity ratings in a group of 103 women diagnosed with endometriosis. Temperament traits were assessed using the Formal Characteristics of Behaviour-Temperament Inventory. Beliefs about pain control were measured using the Polish version of the Beliefs about Pain Control Questionnaire. The Numerical Rating Scale (NRS-11) was used to measure pain intensity. There was a high negative correlation between the temperament trait of endurance and pain intensity ratings...

INTRODUCTION: Recent reports consider endometriosis to be an immunological disorder, thus suggesting potential efficacy of immunomodulators for its treatment. The aim of this study was to assess the effects of oral administration of pentoxifylline on endometriosis-like lesions in a heterologous mice model. STUDY DESIGN: Human endometrial tissue obtained from women (n = 5) undergoing surgery for benign conditions was implanted in nude female mice (n = 30). The animals were distributed into 3 experimental groups receiving: saline 0...

Pancreatic endometriosis is very rare with only a few cases reported in the literature. The imaging features are non-specific and the definitive diagnosis is usually only established after surgery. We report on a 68-year-old woman with left upper quadrant pain who demonstrated a mass in the pancreatic tail on imaging. Laboratory results showed only mildly elevated liver enzymes, tumor markers were within the normal range. A left pancreatectomy was performed, frozen section suggesting a benign lesion, and final histopathology confirmed endometriotic cysts...

Endometriosis is an inflammatory gynecological disorder caused by the growth of endometrial tissue outside the uterus. Endometriosis produces chemokines, including CXCL12, that attract bone marrow cells to the lesions. In this study, we describe the expression, localization, and chemotactic activity of CXCL12 in endometriotic lesions. Biopsies were collected both from women with endometriosis undergoing laparoscopy and control endometrium from women without endometriosis. Expression of CXCl12 and CXCR4 messenger RNA was increased approximately 4- and 6-fold, respectively, in endometriosis compared to eutopic endometrium...
