Objective: To investigate DNA methylation of specific tumor suppressor genes in endometrial hyperplasia compared to normal endometrial tissue. File and methodology: To search for epigenetic events, methylation-specific multiplex ligation-dependent probe amplification was employed to compare the methylation status of 40 tissue samples with atypical endometrial hyperplasia, 40 tissue samples with endometrial hyperplasia without atypia, and 40 control tissue samples with a normal endometrium.

Results and conclusion: Differences in DNA methylation among the groups were found in TWIST1, GATA4, MUS81, and NTRK1 genes (TWIST1: atypical hyperplasia 67.5%, benign hyperplasia 2.5%, normal endometrium 22.5%; P < 0.00001; GATA4: atypical hyperplasia 95%, benign hyperplasia 65%, normal endometrium 22.5%; P < 0.00001; MUS81: atypical hyperplasia 57.5%, benign hyperplasia 22.5%, normal endometrium 5%; P < 0.00001; NTRK1: atypical hyperplasia 65%, benign hyperplasia 27.5%, normal endometrium 10%; P < 0.00001). Higher methylation rates were observed for the tumor suppressor genes of TWIST1, GATA4, MUS81, and NTRK1 in samples with atypical endometrial hyperplasia compared to samples with normal endometrial tissue, and higher methylation rates were found in samples with atypical endometrial hyperplasia compared to samples of benign endometrial hyperplasia. DNA methylation of TWIST1, GATA4, MUS81, and NTRK1 is involved in the pathogenesis of atypical endometrial hyperplasia.

Objective: The objective of this study was to evaluate the Pap smear and colposcopy findings in female inmates in a prison unit in the state of São Paulo, Brazil.

Methods: A retrospective cross-sectional study was carried out by analyzing the Pap smear and colposcopy examinations of female inmates in a prison unit. The following socio-demographic data were assessed: age, nationality, level of education, marital status, height, weight, ethnicity, occupation, religion, sexual orientation, and presence of tattoos.

Results: The sample consisted of 894 women who had a Pap smear, the majority of whom were Brazilian (93.6%), 41.1% had an incomplete primary education, 58.5% were single, 50.1% were white, 60.7% had tattoos, and the predominant religion was Catholicism at 42.8%. Regarding sexual orientation, 124 (13.9%) women identified as bisexual, 640 (71.6%) as heterosexual, and 127 (14.2%) as homosexual. Most Pap smears showed benign findings (86.5%). Of the female inmates who had a Pap smear, 121 (13.5%) were referred for colposcopy. Altered colposcopy findings occurred in 95 (10.6%), with the most common findings being high-grade squamous intraepithelial lesions 36 (4.0%) and low-grade squamous intraepithelial lesions 27 (3.0%). The majority of women (96.0%) had no clinical signs of human papillomavirus - HPV (anogenital verrucous lesions) and only 36 (4.0%) had lesions suggestive of HPV on Pap smears. There were more HIV cases in the group with HPV verrucous lesions (P = 0.013).

Conclusion: We observed 13.5% and 78.5% of abnormal findings in Pap smears and colposcopy, resp.), in female inmates in a prison unit in the state of São Paulo, Brazil.

Endometriosis is a chronic disease characterised by the presence of endometrial tissue outside the uterine cavity, affecting 5-15% of women, especially those of reproductive age. The disease may manifest itself as dysmenorrhoea, dyspareunia, sterility and chronic pelvic pain, among other symptoms. Although it is not malignant, it shares some characteristics with cancer and can lead to epithelial ovarian carcinoma. The risk of malignant transformation of endometriosis is estimated at 1% in premenopausal women and 1-2.5% in postmenopausal women. Our case report describes a 46-year-old female patient with long-standing abdominal pain and a history of surgically confirmed endometriosis. Imaging revealed a cystic mass in the left mesogastrium, which was subsequently surgically removed. Histological examination confirmed the presence of a low-grade endometrioid carcinoma arising from an extragenital endometriosis lesion. Following surgical treatment, the patient underwent adjuvant chemotherapy, after which she was in complete remission. The diagnosis of malignant transformation of endometriosis is complex, requiring a combination of thorough clinical examination, imaging, and histopathological verification. Therapy involves radical surgery and possibly adjuvant chemotherapy, similar to ovarian carcinomas. Despite advances in treatment and research, endometriosis remains a complex disease with unclear aetiology, heterogeneous clinical presentation, and risk of malignant transformation.

Objective: A review of current knowledge on the pathophysiology, diagnostic and treatment options for chronic endometritis in infertile women.

Methods and results: One of the major causes of failed in vitro fertilization (IVF) is undiagnosed intrauterine pathologies, including chronic inflammation of the uterine mucosa - chronic endometritis. However, some authors relativize the negative impact of chronic endometritis on reproductive outcomes. The etiopathogenesis of chronic endometritis is due to qualitative and quantitative changes in the endometrial microbiome with abnormal multiplication of microorganisms naturally occurring in the uterine cavity or vagina. There is no uniform consensus on the most common pathogen causing chronic endometritis. It is characterized by infiltration of plasma cells into the endometrial stroma outside the menstrual cycle, accompanied by hyperaemia and endometrial oedema. Clinical symptoms are very mild or absent. The diagnosis of chronic endometritis is often difficult because there is no specific clinical or laboratory diagnostic method. The following investigative options are commonly used for the diagnosis of chronic endometritis: diagnostic hysteroscopy, histopathological examination of the endometrium including CD 138 immunohistochemistry and culture from the uterine cavity. However, standardised international hysteroscopic and histopathological criteria for accurate diagnosis of chronic endometritis are still lacking. Empirically administered antibiotic therapy improves the success rate of pregnancy and delivery of a viable foetus in infertile patients with proven chronic endometritis. In addition to reviewing the current knowledge of chronic endometritis, this article discusses the importance of hysteroscopy in the diagnostic process.

Conclusion: Chronic endometritis is often a clinically silent disease with negative impact on reproduction in infertile women. Although there are still many unresolved issues, the introduction of hysteroscopy into the diagnostic process is important for clinical practice; however, hysteroscopy even in combination with histological examination of the endometrium, often does not allow an unequivocal diagnosis of chronic endometritis. Further prospective randomised studies in a selected group of women with proven chronic endometritis and repeated failure to implant proven euploid embryos should refine this knowledge.

Introduction: Simulation medicine is no longer just a modern trend and has become a standard part of education and training of the medical staff and students in many countries around the world. Its validity and benefits have been acknowledged and its necessity is reflected in the recommendations of the European Board and College of Obstetrics and Gynaecology.

Objectives: The aim of our work was to map the current state of simulation training at large obstetrics and gynaecology departments in the Czech Republic including the equipment available, teaching environment conditions and human resources and to find out to what extent individual teaching methods are being used in undergraduate and postgraduate education.

Methods: We have collected the information using a questionnaire which focused on the equipment available to the departments, teaching environment conditions, human resources, and types of simulation methods being used in undergraduate and postgraduate training as well as the spectrum of courses being offered.

Results and conclusion: Our finding is that large obstetrics and gynaecology departments in the Czech Republic are well equipped, have good teaching environments available to them, and are able to use most of the current simulation teaching methods. On the other hand, except for an operative vaginal birth course, only a small number of other simulation courses are currently being offered. Data from the survey are further used to discuss the possibilities of developing simulation training in this field in the Czech Republic.

Aim: The aim of the study was to evaluate the influence of a specific diagnosis of infertile women and men on their life quality and psychosexual functioning based on internationally validated questionnaires.

Materials and methods: A total of 853 couples seeking treatment for infertility completed the gender-specific batteries comprised of Fertility Quality of Life tool (FertiQoL), Female Sexual Function Index (FSFI) in women, and Brief Sexual Function Inventory (BSFI) in men. Women were followed in the group of primary and secondary infertility and then with specific diagnoses - polycystic ovary syndrome, tubal factor, endometriosis, and idiopathic sterility. Men's categories reflected spermiogram results, i.e., normozoospermia, merged categories of milder disorders of a spermiogram (teratozoospermia, asthenozoospermia, oligozoospermia, and oligoasthenoteratospermia), oligoasthenoteratospermia (OAT) gravis, azoospermia, and when the man was not examined.

Results: When evaluating the quality of life in women, we found statistically significant differences between primary and secondary sterility. Primary infertile women scored worse especially in the social area. Worse assessment appeared also in mind-body (area evaluating affliction of the body). Emotional and relational domains included similar results in primary and secondary infertile women. With a specific diagnosis, statistically significant differences were not proved. Using the orientational cut-off score, FertiQoL stated that approximately 10% of women experienced adverse quality of life in relation to fertility. In the domain of sexual functioning, 30% of women demonstrated clinically significant dysfunctions. In men, respondents in the normozoospermic and non-diagnosed categories scored higher than those in the merged category and OAT gravis. Only 2% of men felt their quality of life was poor due to fertility, and clinically significant dysfunctions appeared only in 3% of them.

Conclusion: In women, impaired fertility-related quality of life and psychosexual functioning are significantly linked to primary sterility, where specifically the social domain is affected. The impact of a specific diagnosis appears to be minimal. We found high levels of sexual dysfunctions in women. In men, we follow the link of evaluated quality of life in connection with their results of the spermiogram. With spermiogram defects, both areas of functioning can be affected.

Objective: A comprehensive overview of surgical treatment of recurrent gynecological malignancies. Recurrent breast malignancies are not included in this review.

Methodology: A review providing overview of surgical treatment options for recurrent malignancies of adnexa of the uterus (ovary, fallopian tube), uterine corpus, uterine cervix, and carcinoma of the vagina and vulva.

Conclusion: Optimal surgical treatment for patients with recurrent cancer is based on multidisciplinary approach with stratification according to individual prognostic markers. These include patient's performance status, outcome of primary surgery, current extent of recurrence, and histopathological, molecular, and biochemical characteristics. Decision about choice of treatment should be individually discussed and evaluated by the multidisciplinary oncogynecological commission board.

Recent decades have seen a notable increase in cesarean section rates. Although lifesaving, cesarean delivery is associated with an elevated risk of adverse health outcomes in newborns, including respiratory diseases, atopic disorders, obesity, diabetes, and severe autoimmune conditions. The exact mechanisms underlying these associations remain elusive; however, epigenetic modifications have emerged as a plausible molecular basis linking perinatal factors with future disease susceptibility. This review summarizes current literature, revealing that the delivery method may influence epigenetic markers in neonates, primarily through alterations in global DNA methylation and gene-specific methylation patterns.

Pelvic endometriosis is a well-known clinical risk factor for pelvic inflammation and adhesions. We present a complex case of a woman undergoing a cesarean section where the traditional incision on the anterior lower uterine segment was not possible due to a congested pelvis. The newborn was delivered using a posterior uterine wall incision with rotation of the round ligament.

Aim: The aim of this study is to compare the extent of ovarian endometriosis diagnosed at preoperative staging with subsequent perioperative findings. Definition of discrepancies observed according to the #Enzian 2021 classification.

Material and methods: The cohort includes 62 patients of reproductive age with preoperative findings of ovarian endometrioma. Patients were divided according to the #Enzian 2021 classification into subgroups (O1, O2 + O3) with unilateral and bilateral findings. The percentage concordance of preoperative and perioperative findings was evaluated.

Results: In the evaluation of ovarian involvement, the preoperative ultrasound diagnosis shows almost 100% agreement with the findings on the ovaries during surgery. Periadnexal adhesions were predicted preoperatively in only half of the cases. The difference in laterality was confirmed with T3 involvement in the O2 + O3 subgroup. In the bilateral involvement, the finding of the presence of grade 3 adhesions was doubled. An association of ovarian form of endometriosis (O2-O3) with deep infiltrating endometriosis of the small pelvis was observed in 50% of the cohort.

Conclusion: The ovarian form of endometriosis is associated with the occurrence of other endometriosis lesions in the small pelvis. In this study, it was confirmed that preoperative staging underestimates the extent of endometriosis in the small pelvis. In the surgical management of ovarian endometriosis, extensive adhesive process should be expected.
