Background: Endometriosis and adenomyosis are two closely related, estrogen-dependent, benign gynecological diseases. The available evidence on their common pathogenesis and association is limited and often does not address the heterogeneity of both entities. The aim of our study is to investigate the association between different types and localizations of adenomyosis and endometriosis phenotypes, using magnetic resonance imaging (MRI) and laparoscopic findings.

Endometriosis is a disease affecting approximately 10% of reproductive age women. Loss of the tumor suppressor gene AT-rich interactive domain-containing protein 1A (ARID1A) occurs in some endometriosis cases. Histone deacetylase 6 (HDAC-6) is an enzyme with implication in several diseases including different cancer types and immunological disorders, where it is involved in protein trafficking and degradation, cell shape, and migration.

Both endometriosis and ovarian dermoid cysts are benign conditions characterized by the presence of well-differentiated tissues in ectopic locations. The presence and surgical excision of these entities can potentially impact ovarian reserves, contributing to reduced chances of future pregnancy. The objective of our study is to investigate the bidirectional association between endometriosis and ovarian dermoid cysts, as well as to analyze the clinical characteristics of patients diagnosed with both conditions.

Objectives Mental health during pregnancy is a very important public health issue with negative effects on both maternal and child outcomes. The aim of our study is to examine the possible association between conception via in vitro fertilization (IVF) and anxiety or depression during the third pregnancy trimester in the Greek population during the years of financial crisis. Materials and Methods This single-center prospective cohort study was conducted in a tertiary university hospital during the period 2017-2018.

Introduction: Ovarian endometrioma is a common subtype of endometriosis with a prevalence between 17 and 44%. The reported average recurrence of endometrioma after surgical management is 21.5% after 2 years and 40-50% after 5 years.

G protein-coupled estrogen receptor (GPER) has been found to be an important key regulator in the homeostasis of sex hormone-dependent human cells. The aim of this study was to compare the expression of GPER, estrogen receptor alpha (ER-α), estrogen receptor beta (ER-β) and progesterone receptor (PR) in adenomyosis, eutopic endometrium from the same patients, and eutopic endometrium from patients without adenomyosis. Immunohistochemical analysis of GPER, ER-α, ER-β and PR was performed to assess the expression levels on samples of hysterectomies using tissue microarrays.

Background: There is a growing body of human, animal and in vitro studies on vitamin D (vit D) substitution in endometriosis. The aim of this systematic review is to critically appraise and qualitatively synthesize the results of the available studies that examine the supplementation of vit D for endometriosis treatment.

Methods: A systematic search of the literature was conducted in four electronic databases (Medline, Cochrane, Scopus, Embase) and grey literature for original research articles on humans, animals and in vitro models published in any language.

Background: Endosalpingiosis is assumed to be the second most common benign peritoneal pathology after endometriosis in women. Although recent studies indicate a significant association with gynecologic malignancies, many underlying principles remain unclear. This work aimed to systematically describe the intraoperative appearance of endosalpingiosis.

Background: Minimally invasive surgery is the standard approach in early-stage endometrial cancer according to evidence showing no compromise in oncological outcomes, but lower morbidity compared with open surgery. However, there are limited data available on the oncological safety of the use of intrauterine manipulators in endometrial cancer.

Patients And Methods: This prospective multicenter study included patients with endometrial cancer undergoing laparoscopic staging surgery with the use of an intrauterine manipulator.

Superficial papilloma of the ovary is a rare benign ovarian finding, which was first described back in 1895. Here, we present the intraoperative and histological findings of a superficial papilloma of the ovary in a 59-year-old patient.

Article Synopsis
  • Venous thromboembolism (VTE), which includes deep venous thrombosis (DVT) and pulmonary embolism (PE), significantly contributes to maternal mortality during pregnancy due to increased hypercoagulability.
  • Identifying individual risk factors and understanding the changes in pregnancy is crucial for accurate diagnosis and effective treatment, including systemic anticoagulation and possibly advanced interventions like filters or thrombectomy for severe cases.
  • Careful assessment and balancing the risks of anticoagulation against VTE complications are vital for ensuring the safety of both the mother and fetus throughout pregnancy and the postpartum period.

Background: Endometriosis, the presence of endometrial-like tissue outside the uterus, is a common clinical entity between women of reproductive age, with a prevalence of about 10%. Due to the variety of endometriosis-associated symptoms, a great variety of treatments have been implemented. The aim of this review is to give an overview on therapeutical approaches of eight national and international widely used guidelines.

Endosalpingiosis - an Irrelevant Incidental Finding During Laparoscopy? Endosalpingiosis refers to the ectopic presence of tubal epithelium. However, this incidental finding received little attention, although it is the second most common benign peritoneal pathology in women following endometriosis. In contrast to endometriosis, endosalpingiosis shows an increase in prevalence with age beyond the menopause.

Introduction: Endometriosis is an inflammatory condition, affecting mainly women of reproductive age. Leptin is a regulator of food intake and energy expenditure, posing pleiotropic actions, and regulating immunity and fertility. The aim of this study was to systematically review the literature regarding leptin concentrations in biological fluids and tissues of women with endometriosis, and to investigate and propose a possible role of leptin in the pathophysiology of endometriosis.

Torsion of the fallopian tube is when the tube twists on the axis created between the infundibulopelvic ligament and the utero-ovarian ligament. It most commonly presents with appendicitis-like symptoms, such as abdominal pain, nausea and vomiting. Because of its rarity and non-specific symptoms, it is usually misdiagnosed initially, which delays therapy, at the expense of the preservation of fertility.

Class I histone deacetylases (HDACs-1-3) play an important role in steroid hormone-dependent gene expression and in modulating cell survival and proliferation. We analyzed their expression in a tissue microarray including 74 endometriosis samples and 30 normal endometrium controls. The mean HDAC-1 immunoreactivity score (IRS ± standard deviation) was 7.

Background: The G protein-coupled estrogen receptor (GPER) is thought to be involved in non-genomic estrogen responses as well as processes such as cell proliferation and migration. In this study, we analyzed GPER expression patterns from endometriosis samples and normal endometrial tissue samples and compared these expression profiles to those of the classical sex hormone receptors.

Methods: A tissue microarray, which included 74 samples from different types of endometriosis (27 ovarian, 19 peritoneal and 28 deep-infiltrating) and 30 samples from normal endometrial tissue, was used to compare the expression levels of the GPER, estrogen receptor (ER)-alpha, ER-beta and progesterone receptor (PR).

Mutations of the tumor-suppressor gene ARID1A result in the loss of protein expression of the BRG-associated factor 250a (BAF250a), a large subunit of transcription-regulating Human SWI/SNF complexes, which have an important role in the control of cell proliferation and tumor suppression. ARID1A mutations are particularly frequent in endometriosis-associated ovarian clear cell and endometrioid carcinomas, and were recently described as a possible key mechanism and early step in the transformation of endometriosis into cancer. Here, we examined the immunohistochemical expression pattern of BAF250a in a tissue microarray including 74 endometriosis and 30 endometrium samples.
