Endometriosis is a common,estrogen-dependent,inflammatory,gynecologic disease process in which normal endometrial tissue is abnormally present outside the uterine cavity.[1]Endometriosis is a common cause of chronic pain,dyspareunia,dysmenorrhea,and infertility.Most commonly,endometriosis is found within the pelvis,specifically on the ovaries.Because of rupture,bleeding,infection,or torsion,ovarian endometriosis(OMA)may cause acute abdominal pain,which is similar to acute abdominal pain caused by other reasons and is not easy to diagnose.[2,3]Determining the clinical and pathological features of OMA is crucial for accurate assessment,diagnosis,and treatment. 展开更多

Endometriosis is a common chronic gynecological disease with endometrial cell implantation outside the uterus.Angiogenesis is a major pathophysiology in endometriosis.Our previous studies have demonstrated that the prodrug of epigallocatechin gallate(ProEGCG)exhibits superior anti-endometriotic and anti-angiogenic effects compared to epigallocatechin gallate(EGCG).However,their direct binding targets and underlying mechanisms for the differential effects remain unknown.In this study,we demonstrated that oral ProEGCG can be effective in preventing and treating endometriosis.Additionally,1D and 2D Proteome Integral Solubility Alteration assay-based chemical proteomics identified metadherin(MTDH)and PX domain containing serine/threonine kinase-like(PXK)as novel binding targets of EGCG and ProEGCG,respectively.Computational simulation and BioLayer interferometry were used to confirm their binding affinity.Our results showed that MTDH-EGCG inhibited protein kinase B(Akt)-mediated angiogenesis,while PXK-ProEGCG inhibited epidermal growth factor(EGF)-mediated angiogenesis via the EGF/hypoxia-inducible factor(HIF-1a)/vascular endothelial growth factor(VEGF)pathway.In vitro and in vivo knockdown assays and microvascular network imaging further confirmed the involvement of these signaling pathways.Moreover,our study demonstrated that ProEGCG has superior therapeutic effects than EGCG by targeting distinct signal transduction pathways and may act as a novel antiangiogenic therapy for endometriosis. 展开更多

Introduction: Cutaneous endometriosis is an uncommon but well-known skin disorder that represents about 0.5% to 1% of all endometriosis. The objective of this case series is to report clinical presentation, diagnosis, and management of various forms of cutaneous endometriosis. Material and Methods: It was an observational, retrospective and descriptive review of cases presenting with cutaneous endometriosis among Cameroonian women managed at the gynaecological outpatient department of Yaounde Gynaeco-Obstetric and Pediatric Hospital. All the following parameters were analysed: age, parity, previous pelvic surgery, presenting symptoms and duration, associated symptoms, localizations, imaging, size of the lesion, other localization of endometriosis, management and histopathological results. Results: we reported 4 cases of cutaneous endometriosis, with 3 umbilical endometriosis and 1 abdominal scar endometriosis. Patient age ranged from 28 to 39 years with an average of 33 years. All patients described infertility (two primary and two secondary) and two had a history of abdominal surgery. All patients presented local cyclical signs such as pain, swelling, color change and bleeding. The duration of symptoms varied from 2 to 3 years and the size of lesions ranged from 2 to 3.5 cm for umbilical lesions and was 9 cm for abdominal scar endometriosis. In all cases, no imaging was required for the diagnosis, which was suspected on the basis of patient’s history and the cyclical nature of local signs, followed by wide surgical excision and confirmation on histopathology. Conclusion: Cutaneaous endometriosis is a rare benign condition. Umbilical endometriosis seems to be the main cutaneous localization and can be described as primary or secondary. Even if its diagnosis must be confirmed by histopathology, it should be considered in patient with cutaneous cyclic signs such as pain, swelling or bleeding with or without history of abdominal surgery. 展开更多

BACKGROUND Endometriosis is a chronic inflammatory condition affecting a significant proportion of women of reproductive age.Although laparoscopic surgery is commonly the preferred treatment,the decision to preserve or remove the ovaries remains controversial.Previous studies have yielded inconsistent results regarding the impact of ovarian preservation vs oophorectomy on fertility outcomes and disease recurrence.This prospective study aimed to address this knowledge gap by comparing the effects of these surgical approaches on spontaneous pregnancy rates,time to pregnancy,recurrence rates,and postoperative pain in patients with endometriosis.AIM To compare the reproductive outcomes and recurrence rates between ovarian preservation and oophorectomy in women undergoing laparoscopic surgery for endometriosis.METHODS This study was conducted at a tertiary care hospital between January 2019 and December 2023.A total of 312 women aged 18 to 40 years,diagnosed with endometriosis and undergoing laparoscopic surgery,were included.The patients were categorized into the ovarian preservation group(n=204)and the oophorectomy group(n=108).The primary outcome measure was the achievement of spontaneous pregnancy within 24 months post-surgery.Secondary outcomes included time to spontaneous pregnancy,recurrence rates,and postoperative pain scores.RESULTS The ovarian preservation group exhibited a significantly higher spontaneous pregnancy rate than that in the oophorectomy group(43.6%vs 28.7%,P=0.006).Moreover,the median time to spontaneous pregnancy was shorter in the ovarian preservation group(8.2 months vs 11.4 months,P=0.018).Nonetheless,endometriosis recurrence was more prevalent in the ovarian preservation group(22.1%vs 11.1%,P=0.014).The postoperative pain scores demonstrated similar improvements in both groups,with no significant differences observed.Subgroup analyses indicated that the benefit of ovarian preservation on spontaneous pregnancy rates was more evident among younger women(≤35 years)and those with advanced-stage endometriosis.CONCLUSION Ovarian preservation is associated with a high spontaneous pregnancy rate and a short time to pregnancy.However,because of the increased risk of recurrence,the decision should be based on age,fertility aspirations,and disease severity. 展开更多

BACKGROUND The occurrence of postoperative depression and anxiety in patients with endomet-riosis(EMS)not only causes psychological distress,but may also harm their physical health.AIM To explore the postoperative depression status,and its influencing factors,of EMS patients with reproductive intention.METHODS A total of 321 EMS patients with reproductive intent were included.Using the self-rating anxiety scale and self-rating depression scale,EMS patients with anxiety or depression were distinguished.A clinical model for predicting anxiety or depression in EMS patients was constructed and evaluated using a nomogram,receiver operating characteristic curve,and calibration curve.RESULTS The results of the single factor analysis showed that smoking,coffee,EMS stage,chronic pelvic pain,and sexual discomfort may be related to anxiety.Further,smoking,drinking,spouse,annual household income and EMS stage may be related to depression in EMS patients.Multivariate logistic regression illustrated that smoking,coffee,chronic pelvic pain and sexual discomfort may be inde-pendent risk factors for anxiety in EMS patients,while smoking,EMS stage(Phase III and Phase IV),spouse and high annual household income may be independent risk factors for depression in EMS patients.Additionally,the models used to predict the risk of anxiety or depression in EMS patients have good predictive value.CONCLUSION The anxiety and depression of EMS patients may be related to many factors.In clinical treatment,additional attention should be paid to the psychological status of EMS patients. 展开更多

BACKGROUND Currently,the use of dienogest in clinical practice has increased significantly,and many studies have focused on its effectiveness and safety in the treatment of endometriosis and adenomyosis;however,the effects of treatment with dienogest on uterine fibroid size in patients with endometriosis or adenomyosis have not been investigated.AIM To explore changes in fibroid size in patients with concomitant uterine fibroids undergoing dienogest treatment for endometriosis or adenomyosis and to evaluate the effectiveness and safety of the drug.METHODS The clinical data of patients with uterine fibroids treated with dienogest for endometriosis or adenomyosis at Peking University First Hospital from January 2021 to January 2023 were retrospectively analyzed.RESULTS The maximum uterine fibroid diameter and volume increased after 3 months,6 months and 1 year of dienogest treatment compared with those before treatment(P<0.01).The maximum diameter and volume of the uterine adenomyoma increased after 3 months of dienogest treatment but decreased after 6 months and 1 year of treatment compared with those before treatment,but the difference was not significant(P>0.05).Endometrial thickness and antigen 125 levels were significantly thinner and decreased,respectively,after dienogest treatment(P<0.01).Pearson's correlation analysis revealed that the increase in uterine fibroid volume after 3 months of dienogest treatment was positively correlated with the basic uterine fibroid volume(r=0.792,P<0.01).Among 64 patients with dysmenorrhea,63 experienced significant relief of dysmenorrhea after 6 months of treatment with dienogest,and all patients experienced significant relief of dysmenorrhea after 12 months.Patients were able to tolerate the drugs,with an average drug tolerance score of 8.73.CONCLUSION The use of dienogest in patients with endometriosis or adenomyosis combined with uterine fibroids can effectively relieve the patient's pain symptoms and significantly reduce the sizes of ovarian endometriotic cysts,but it cannot inhibit uterine fibroid growth. 展开更多

Endometriosis is an estrogen-dependent inflammatory disease,defined by the presence of functional endometrial tissue outside of the uterine cavity.This disease is one of the main gynecological diseases,affecting around 10%-15%women and girls of reproductive age,being a common gynecologic disorder.Although endometriosis is a benign disease,it shares several characteristics with invasive cancer.Studies support that it has been linked with an increased chance of developing endometrial ovarian cancer,representing an earlier stage of neoplastic processes.This is particularly true for women with clear cell carcinoma,low-grade serous carcinoma and endometrioid.However,the carcinogenic pathways between both pathologies remain poorly understood.Current studies suggest a connection between endometriosis and endometriosis-associated ovarian cancers(EAOCs)via pathways associated with oxidative stress,inflammation,and hyperestrogenism.This article aims to review current data on the molecular events linked to the development of EAOCs from endometriosis,specifically focusing on the complex relationship between the immune response to endometriosis and cancer,including the molecular mechanisms and their ramifications.Examining recent developments in immunotherapy and their potential to boost the effectiveness of future treatments. 展开更多

Objective:To explore the effect of Hupo powder(HP)on autophagy in menstrual blood-derived stem cells(MenSCs)with endometriosis(EMT).Methods:EMT MenSCs(E-MenSCs)and healthy MenSCs(H-MenSCs)were isolated from the menstrual blood of patients with EMT and healthy female participants,respectively.We identified their stem cells’characteristics via adipogenic and osteogenic differentiation.Twelve male SpragueeDawley rats received 0.9% NaCl and HP-dispensing granules by gastric irrigation to prepare blank serum and medicated serum,respectively.We used serum concentrations of 5%,10%,and 20%,each at administered times of 12,24,and 48 h to select the best condition.These cells were divided into three groups:blank serum of the control group,blank serum of the model group,and medicated serum of the HP group.H-MenSCs were used in the control group,while E-MenSCs were used in the model and HP groups.We analyzed cell viability using a cell counting kit-8 assay,observed cell morphology,evaluated the amounts of auto-phagosomes and autolysosomes by transmission electron microscopy,and detected the protein expression of autophagy markers(LC3-II and Beclin1)by Western blot.Results:E-MenSCs and H-MenSCs became long fusiform with a diffuse radial pattern,forming lipid droplets and calcium nodules after adipogenic and osteogenic differentiation.We then used the best conditiond 20% serum and 48 hdfor the subsequent experiments.In contrast to the model group,the HP group exhibited lower cell viability(=0.007),larger amounts of autophagosomes and autolysosomes(P<0.001 and P=0.001,respectively),and higher expression of LC3-II and Beclin1(P=0.021 and P=0.019,respectively).Conclusion:Hupo powder can promote autophagy in E-MenSCs,which might be one of the mechanisms underlying its therapeutic effects. 展开更多

Endometriosis is a clinical and recurrent condition characterized by the presence of functional endometrial tissue outside the uterine cavity and myometrium. It is estimated that 6% to 10% of women of reproductive age, 50% to 60% of adolescents and adults with pelvic pain, and up to 50% of women with infertility are pregnant from the condition. However, this proportion tends to be even greater due to the difficulty in diagnosing it: because it presents different symptoms, lack of information from health professionals, and a high-cost diagnostic test. Another aggravating factor is the average time from the onset of symptoms to the medical diagnosis, which even today ranges from five to ten years;this delay has consequences for disease progression, as it prevents early treatment, which is important for improving pain levels and physical and psychological well-being. Aware of these mishaps, it is therefore important to assess the difficulties faced by doctors in the diagnosis of endometriosis in the public health system, in Brazil, the Unified Health System (SUS). With this purpose, a cross sectional was carried out, developed in the virtual environment using traffic in Google forms, with the difficulties quantified in the Likert scale. Participating physicians pointed out a medium difficulty for patients with endometriosis to access the consultation (58%) and moderate difficulty (52%) to perform an ultrasound examination;also signaled great difficulty in performing magnetic resonance imaging (77%) and laparotomy (61%) in these patients. It is hoped that knowledge about the difficulties faced by physicians in the diagnosis of endometriosis in the SUS will give these physicians a voice and corroborate, even if minimally, so that there is more research that provokes the search for these difficulties, in order to improving the quality of life of these women. 展开更多
