Abstract
A patients' increasing interest in dietary modifications as a possible complementary or alternative treatment of endometriosis is observed. Unfortunately, the therapeutic potential of dietary interventions is unclear and to date no guidelines to assist physicians on this topic exist. The aim of this study, therefore, was to systematically review the existing studies on the effect of dietary interventions on endometriosis. An electronic-based search was performed in MEDLINE and COCHRANE. We included human and animal studies that evaluated a dietary intervention on endometriosis-associated symptoms or other health outcomes. Studies were identified and coded using standard criteria, and the risk of bias was assessed with established tools relevant to the study design. We identified nine human and 12 animal studies. Out of the nine human studies, two were randomized controlled trials, two controlled studies, four uncontrolled before-after studies, and one qualitative study. All of them assessed a different dietary intervention, which could be classified in one of the following principle models: supplementation with selected dietary components, exclusion of selected dietary components, and complete diet modification. Most of the studies reported a positive effect on endometriosis; they were however characterized by moderate or high-risk bias possibly due to the challenges of conducting dietary intervention trials. According to the available level of evidence, we suggest an evidence-based clinical approach for physicians to use during consultations with their patients. Further well-designed randomized controlled trials are needed to accurately determine the short-term and long-term effectiveness and safety of different dietary interventions.

Abstract
ABSTRACT Endocannabinoid (eCB) levels fluctuate in inflammatory conditions and as such may take part in endometriosis-associated pain or even in endometriosis pathogenesis. In this case-control (23 cases and 19 controls) study, targeted lipids were measured in the serum and peritoneal fluid collected during laparoscopy. Endometriosis was confirmed histologically. Dysmenorrhea, abdominal pain, and dyspareunia were assessed using the Numeric Rating Scale for pain. Steroids, eCBs, and related lipids were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Tumor necrosis factor alpha, IL-8, PAPP-A, PP14, RANTES, OPG, MIDKINE, MCP-1, VEGF, leptin, and defensins were quantified by ELISA. We found that eCB levels were significantly influenced by both noncyclic and cyclic abdominal pain. Specifically, women suffering from noncyclic abdominal pain were characterized by a higher 2-AG level in the peritoneal fluid throughout the menstrual cycle, whereas women suffering from dysmenorrhea had higher 2-AG levels and lower AEA levels during the proliferative phase alone. In addition, 2-AG positively correlated with prostaglandin E2 (PGE2), and the ratio AEA/2-AG positively correlated with defensins, suggesting a possible link between endocannabinoids system and inflammatory pain. The results of the current study indicate that the eCB system may play a role in endometriosis-associated pain, but additional studies are needed to investigate the causal relationship.

Abstract
INTRODUCTION Preliminary clinical evidence suggests a detrimental effect of pathogenic variants of BRCA1 and 2 genes on fertility outcome. This meta-analysis evaluates whether women carrying BRCA mutations (BRCAm) have decreased ovarian reserve, in terms of Anti-Muellerian Hormone (AMH), compared to women without BRCAm (wild-type). MATERIAL AND METHODS Systematic searches of PubMed, Medline, Scopus, Embase, Science Direct and the Cochrane Library from inception until July 2020 were conducted. All studies comparing AMH level in fertile age women, with and without BRCA pathogenic variants were considered. Sub-analyses were performed according to age, presence of breast cancer, and type of mutation. RESULTS Among 64 studies, 10 series were included. For the entire cohort, a trend of reduced AMH level were found between BRCAm carriers and women without pathogenic variants. BRCAm carriers aged 41-years or younger had lower AMH levels compared to 41-years or younger wild type women (OR: 0.73 [95%CI-1.12;-0.35]; p = 0.0002). This finding was confirmed for BRCA1m carriers (OR: 1 [95%CI-1.96;-0.05]; p = 0.004) whereas no difference was observed between BRCA2m carriers and wild type women. The same analysis on breast cancer patients with and without BRCAm achieved the same results. CONCLUSION Young BRCA1m carriers seem to have lower AMH level compared with wild type women and therefore a potential decreased ovarian reserve.

Abstract
OBJECTIVE To investigate factors predicting the risk of developing 90-day postoperative complications and lymphatic-specific morbidity in patients undergoing surgical staging for high-risk endometrial cancer. METHODS This is a multi-institutional retrospective cohort study. Patients affected by apparent early-stage high-risk endometrial cancer (endometrioid FIGO grade 3 with deep myometrial invasion and non-endometrioid endometrial cancer) undergoing surgical staging between 2007 and 2019. Complications were graded according to the Clavien-Dindo classification system. Martin criteria were applied to improve quality of complications reporting. RESULTS Charts of 279 patients were evaluated. Lymphadenectomy, sentinel node mapping (SNM), and SNM followed by back-up lymphadenectomy were performed in 83 (29.7%), 50 (17.9%), and 146 (52.4%) patients, respectively. The former group of patients included 13 patients who had lymphadenectomy after the failure of the SNM technique. Thirteen (4.6%) patients developed severe postoperative events (grade 3 or worse). At multivariate analysis, body mass index (OR: 1.08 (95%CI: 1.01, 1.17)) and open abdominal surgery (OR: 2.27 (95%CI: 1.02, 5.32)) were the two independent factors predictive of surgery-related morbidity. Seven severe lymphatic complications occurred. The adoption of laparoscopic approach (p < 0.001, log-rank test) and SNM (p = 0.038, log-rank test) correlated with a lower risk of developing surgery-related events. Independently, open abdominal surgery was associated with an increased risk of developing lymphatic morbidity (OR: 37.4 (95%CI: 4.38, 319.5); p = 0.001). CONCLUSION The adoption of the laparoscopic approach and SNM technique were associated with lower 90-day complication rates than open surgery in high-risk endometrial cancer undergoing staging surgery.

Epithelial-to-mesenchymal transition contributes to the downregulation of progesterone receptor expression in endometriosis lesions. J Steroid Biochem Mol Biol 2021; 212:105943.

Abstract
Endometriosis is a common, estrogen-dependent disease, in which endometrial tissue grows in the peritoneal cavity. These lesions often express low levels of progesterone receptors (PR), which potentially play an important role in the insufficient response to progestin treatment. Here, we uncover an interconnection between the downregulated PR expression and the epithelial-to-mesenchymal transition (EMT) in endometriotic lesions. The majority of ectopic epithelial glands (93.1 %, n = 67/72) display heterogeneous states of EMT by immunohistochemistry staining. Interestingly, low PR expression associated with high N-cadherin expression, a hallmark of EMT. In order to gain mechanistic insights, we performed in vitro functional assays with the endometriotic epithelial cell lines EM'osis and 12Z. TGF-β-induced EMT, marked by elevations of CDH2 and SNAI1/2, led to a significant downregulation of PR gene expression in both cell lines. In contrast, silencing of SNAI1 in EM'osis and of SNAI1 plus SNAI2 in 12Z elevated PR gene expression significantly. We found that not only in vitro, but also in the epithelial component of endometriotic lesions strong expression of SNAI1/2 concurred with weak expression of PR. In summary, these results suggested the negative correlation association of the heterogeneous states of EMT and suppressed PR expression in endometriotic lesions. Our functional assays indicate that EMT contributes to the downregulation of PR expression via the upregulation of EMT-TFs, like SNAI1 and SNAI2, which may ultimately lead to progesterone resistance.

Abstract
Problem Repeated implantation failure and recurrent pregnancy loss are associated with chronic endometritis, a persistent endometrial inflammation. Its diagnosis and treatment may increase pregnancy and live birth rates. The aim of this study was to assess the effectiveness of endometrial diagnostic biopsy and subsequent antibiotic treatment in cases of chronic endometritis on reproductive outcomes over a long observation period. Method of Study We conducted a historical cohort study (2014–2018) at our University‐based infertility center that included women (n = 108) with repeated implantation failure or recurrent pregnancy loss without known pathologies associated with either condition. Forty‐one women underwent a hysteroscopy only (reference group); the remaining 67 women underwent, in addition to the hysteroscopy, an endometrial diagnostic biopsy with immunohistochemically staining for CD138 to detect plasma cells (biopsy group). If one or more plasma cells were detected, the women were treated with doxycycline 100 mg twice a day orally for 2 weeks. We performed stratified survival analysis (Kaplan‐Meier) and Cox regression. Results The biopsy group had higher chances of pregnancy (hazard ratio 2.28; 95% confidence interval 1.23–4.24; p = .009) and of live birth (hazard ratio 2.76; 95% confidence interval 1.30–5.87; p = .008) compared with the reference group. In the sensitivity analysis, repeated implantation failure or recurrent pregnancy loss did not affect the outcome. Conclusion Endometrial diagnostic biopsy followed by antibiotic treatment in case of chronic endometritis in women with repeated implantation failure or recurrent pregnancy loss may increase the chances for live birth.

Abstract
INTRODUCTION In 2021, a joint ESGO/ESTRO/ESP committee updated their evidence-based guidelines for endometrial cancer, recommending a new risk grouping incorporating both clinicopathologic and molecular parameters. We applied the new risk grouping and compared the results to those of the prior 2016 clinicopathologic system. MATERIALS AND METHODS We classified molecularly a cohort of 604 women diagnosed with endometrial cancer using immunohistochemistry for TP53 and MMR proteins on a tissue microarray, as well as Sanger sequencing for POLE mutations. These results, combined with clinicopathologic data, allowed the patients to be risk grouped using both the new 2021 molecular/clinicopathologic parameters and the prior 2016 clinicopathologic system. RESULTS The application of the 2021 molecular markers shows Kaplan-Meier curves with a significant difference between the groups for all survival. Molecular classification under the 2021 guidelines revealed a total of 39 patients (39/594, 7%) with a change in risk group in relation to the 2016 classification system: the shift was alone due to either P53abn or POLEmut molecular marker. In order to ensure correct 2021 molecular risk classification, not all patients with endometrial cancer need a molecular diagnostic: 433 (72.9%) cases would need to be analyzed by TP53 IHC, only 46 (7.7%) by MMR IHC and 286 (48.1%) POLE sequencing reactions. CONCLUSION Application of the 2021 molecular risk groups is feasible and shows significant differences in survival. IHC for TP53 and MMR and applying POLE sequencing is only needed in selected cases and leads to shifting risk groups both upward and downward for a sizeable number of patients. It is possible to significantly reduce the number of analyses required to implement the classification if resources are limited.

Abstract
Simple Summary Axillary dissection is a highly mobile procedure with severe lymphatic consequences. The off-label application of fibrin sealants in the axilla, with the sole aim to eliminate dead space and to provoke sealing of the disrupted lymphatic vessels at the end of axillary dissection, is an experimental procedure to reduce lymphatic morbidity. The aim of our systematic review and meta-analysis is to investigate the effects of fibrin sealants on lymphatic morbidity after axillary dissection. Our results show that this experimental procedure is able to decrease the total axillary drainage output, the number of days before the axillary drainage is removed, and the length of hospital stay. However, no effects on the occurrence rate of axillary lymphocele or on the surgical site complications rate were demonstrated Abstract Background: use of fibrin sealants following pelvic, paraaortic, and inguinal lymphadenectomy may reduce lymphatic morbidity. The aim of this meta-analysis is to evaluate if this finding applies to the axillary lymphadenectomy. Methods: randomized trials evaluating the efficacy of fibrin sealants in reducing axillary lymphatic complications were included. Lymphocele, drainage output, surgical-site complications, and hospital stay were considered as outcomes. Results: twenty-three randomized studies, including patients undergoing axillary lymphadenectomy for breast cancer, melanoma, and Hodgkin’s disease, were included. Fibrin sealants did not affect axillary lymphocele incidence nor the surgical site complications. Drainage output, days with drainage, and hospital stay were reduced when fibrin sealants were applied (p < 0.0001, p < 0.005, p = 0.008). Conclusion: fibrin sealants after axillary dissection reduce the total axillary drainage output, the duration of drainage, and the hospital stay. No effects on the incidence of postoperative lymphocele and surgical site complications rate are found.

Abstract
Background This study aimed to evaluate the clinical value of indocyanine green sentinel lymph node (SLN) mapping in patients with vulvar cancer. The conventional procedure of SLN mapping in vulvar cancer includes peritumoral injection of technetium-99m nanocolloid before surgery and intraoperative injection of a blue dye. However, these techniques harbor some limitations. Near-infrared fluorescence imaging with indocyanine green has gained popularity in SLN mapping in different types of cancer. Methods We analyzed retrospectively vulvar cancer patients at our institution between 2013 and 2020 undergoing indocyanine green SLN mapping by applying video telescope operating microscope system technology. Results 64 groins of 34 patients were analyzed. In 53 groins we used technetium-99m nanocolloid, in four patent blue, and in five both techniques, additionally to indocyanine green for SLN detection. In total, 120 SLNs were identified and removed. The SLN detection rate of indocyanine green was comparable to technetium-99m nanocolloid (p=.143) and higher than patent blue (p=.003). The best results were achieved using a combination of ICG and technetium-99m nanocolloid (detection rate of 96.9%). SLN detection rates of indocyanine green were significantly higher in patients with positive lymph nodes (p=.035) and lymphatic space invasion (p=.004) compared to technetium-99m nanocolloid. Conclusion Indocyanine green SLN mapping in vulvar cancer is feasible and safe, with reasonable detection rates. Due to its easy application and few side effects, it offers a sound alternative to the conventional SLN mapping techniques in vulvar cancer. In patients with lymph node metastasis, indocyanine green even outperformed technetium-99m nanocolloid in terms of detection rate.

Abstract
Endometrial cancer care has undergone major changes in the past 30 years. In 1988, staging transitioned from clinical to surgical. Moreover, the surgical approach of choice is no longer open surgery, but minimally invasive surgery. An improvement in terms of nodal evaluation followed. Full systematic lymphadenectomy has been continuously replaced by sentinel lymph node mapping. Although sentinel lymph node mapping with a cervical injection of indocyanine green dye is rapidly gaining clinical acceptance, we lack consistent recommendations on a well-defined procedure that accurately and indolently assesses the lymph node status. Such recommendations are indispensable, as nodal status is the most important predictive factor of survival and is essential for tailoring adjuvant treatment to the risk of recurrence. This paper focuses on transitions in endometrial cancer care and highlights current data on sentinel lymph node mapping in endometrial cancer. We demonstrate that sentinel lymph node mapping is a safe and accurate strategy for nodal status evaluation with appropriate sensitivity, false-negative rate and negative predictive value in high- as well as low-risk settings. Furthermore, we elaborate on type and dose of tracer, site of injection, number of sentinel lymph nodes to be removed, sentinel lymph node mapping learning curve, operation mode and sentinel lymph node ultrastaging. In the future, guidelines with consistent recommendations on the above outlined features of sentinel lymph node mapping should be established to allow for a uniform and wide-spread application of the sentinel lymph node mapping procedure.

Abstract
INTRODUCTION Aim of this study was the evaluation of prevalence of HPV infection and resulting genital dysplasia to assess the necessity and reasonability of pap smears and HPV testing in transgender patients. HPV is the most common sexually transmitted infection and responsible for the majority of genital dysplasias and malignancies. However, few data exist about the prevalence of HPV and dysplasia in transgender people. METHODS This retrospective data analysis of prospectively collected data includes all patients seen in our specialized outpatient clinic for transgender people. Gynecologic exam, colposcopy, cellular swabs and HPV typing were carried out. Primary endpoint was the prevalence of HPV and genital dysplasias in transgender patients. Secondary endpoints were the subtypes of HPV, demographic data, sexual orientation and co-morbidities in these patients. RESULTS We investigated overall 98 patients whereof 53 were transwomen and 45 transmen. Of those, 10.2 % had positive HPV tests and 10.2 % dysplastic changes in the PAP and one case of invasive anal carcinoma (1.02 %). Comorbidities included recurrent urinary tract infections, psychologic comorbidies and other, possibly hormone replacement related conditions. CONCLUSION The results underline the necessity of a routine gynecological examination including PAP and/or HPV screening and vaccinating, respectively, no matter of sexual orientation or comorbidities. Monitoring the existent anatomy may prevent invasive carcinoma requiring more invasive therapies. Moreover, concomitant pathologies are present and require long-term care of these patients almost all using hormone therapy and carrying several specific risk factors. Transgender-focused guidelines to take into account these peculiarities are needed.

Abstract
INTRODUCTION Long-term survivors of ovarian cancer are a unique group of patients in whom prognostic factors for long-term survival have been poorly described. Such factors may provide information for a more personalized therapeutic approach. The objective of this study is to determine further characteristics of long-term survivors with high-grade serous ovarian cancer. METHODS Long-term survivors were defined as patients living longer than 8 years after first diagnosis and were recruited within seven high volume centers across Europe from November 1988 to November 2008. The control group included patients with high-grade serous ovarian cancer with less than 5 years' survival identified from the systematic 'Tumorbank ovarian cancer' database. A subanalysis of Charité patients only was performed separately for in-depth analysis of tumor dissemination. Propensity score matching with nearest-neighbor caliper width was used to match long-term survivors and the control group regarding age, FIGO stage, and residual tumor. RESULTS A total of 276 patients with high-grade serous ovarian cancer were included, divided into 131 long-term survivors and 145 control group patients. After propensity score matching and multivariable adjustment, platinum sensitivity (p=0.002) was an independent favorable prognostic factor whereas recurrence (p<0.001) and ascites (p=0.021) were independent detrimental predictors for long-term survival. Significantly more long-term survivors tested positive for mutation in the BRCA1 gene than the BRCA2 gene (p=0.016). Intraoperatively, these patients had less tumor involvement of the upper abdomen at initial surgery (p=0.024). Complexity of surgery and surgical techniques were similar in both cohorts. CONCLUSION Platinum sensitivity constitutes a favorable factor for long-term survival whereas tumor involvement of the upper abdomen, ascites, and recurrence have a negative impact. Based on clinical estimation, long-term survival is associated with combinations of clinical, surgical, and molecular factors.

Abstract
ZusammenfassungDie Adenomyose ist durch endometriale Zellen im Myometrium charakterisiert. Zu den klinischen Beschwerden gehören Schmerzen, Blutungsstörungen und beeinträchtigte Fertilität. Die Abklärung beinhaltet eine gute Anamnese und die Bildgebung mit transvaginalem Ultraschall (TVUS) sowie ggf. Magnetresonanztomographie. Klassisch zeigt sich die Adenomyose im TVUS durch partielle Aufhebung der Junktionalzone. Die Therapie erfolgt ganzheitlich und beinhaltet ein gutes Schmerzmanagement. Bei jungen Patientinnen sollte eine endokrine Therapie erfolgen. Die Kinderwunschtherapie kann mit einer 3‑monatigen Down-Regulation mit Gonadotropin-Releasing-Hormon(GnRH)-Analoga eingeleitet werden. Bei notwendiger In-vitro-Fertilisation haben Protokolle mit ultralanger Down-Regulation oder zeitlich versetztem Embryotransfer nach GnRH-Analoga bessere Resultate gezeigt. Bei fortgeschrittener Erkrankung, abgeschlossener Familienplanung oder Therapieresistenz kommt die operative Sanierung oder Hysterektomie infrage.

Abstract
OBJECTIVE Sentinel node mapping (SLN) has replaced lymphadenectomy for staging surgery in apparent early-stage low and intermediate risk endometrial cancer (EC). Only limited data about the adoption of SNM in high risk EC is still available. Here, we evaluate the outcomes of high-risk EC undergoing SNM (with or without back-up lymphadenectomy). METHODS This is a multi-institutional international retrospective study, evaluating data of high-risk (FIGO grade 3 endometrioid EC with myometrial invasion >50% and non-endometrioid histology) EC patients undergoing SNM followed by back-up lymphadenectomy and SNM alone. RESULTS Chart of consecutive 196 patients were evaluated. The study population included 83 and 113 patients with endometrioid and non-endometrioid EC, respectively. SNM alone and SNM followed by back-up lymphadenectomy were performed in 50 and 146 patients, respectively. Among patients having SNM alone, 14 (28%) were diagnosed with nodal disease. In the group of patients undergoing SNM plus back-up lymphadenectomy 34 (23.2%) were diagnosed with nodal disease via SNM. Back-up lymphadenectomy identified 2 (1%) additional patients with nodal disease (in the para-aortic area). Back-up lymphadenectomy allowed to remove adjunctive positive nodes in 16 (11%) patients. After the adoption of propensity-matched algorithm, we observed that patients undergoing SNM plus back-up lymphadenectomy experienced similar disease-free survival (p = 0.416, log-rank test) and overall survival (p = 0.940, log-rank test) than patients undergoing SLN alone. CONCLUSIONS Although the small sample size, and the retrospective study design this study highlighted that type of nodal assessment did not impact survival outcomes in high-risk EC. Theoretically, back-up lymphadenectomy would be useful in improving the removal of positive nodes, but its therapeutic value remains controversial. Further prospective evidence is needed.

Abstract
STUDY OBJECTIVE To evaluate the prognostic value of pre- and perioperative factors for voiding dysfunction after surgery for deep infiltrating endometriosis (DIE). DESIGN Single-center retrospective cohort study. SETTING University hospital. PATIENTS A total of 198 women with DIE in the posterior compartment who underwent surgery and a postoperative bladder scan. INTERVENTIONS Surgical resection of the DIE nodule from the dorsal compartment. MEASUREMENTS AND MAIN RESULTS After surgery, 41% of the patients initially experienced voiding dysfunction (defined as >100 mL postvoid residual urine volume at second bladder scan). The number decreased to 11% by the time of hospital discharge. Among those with a need for self-catheterization after discharge (n = 17), voiding dysfunction lasted for a median of 41 days before a return to normal bladder function, with a residual urine volume of <100 mL. The preoperative presence of DIE nodules in the ENZIAN compartment B was associated with postoperative voiding dysfunction (p = .001). The hazard ratio for elevated residual urine volume was highest when the disease stage was B3 (hazard ratio 6.43; CI, 2.3-18.2; p <.001), describing a nodule diameter of >3 cm in lateral distension. Receiver operating characteristic curve analyses showed that a first residual urine volume >220 mL has a good predictive value for the risk of intermittent self-catheterization (area under the receiver operating characteristic curve 0.893; p <.001). CONCLUSION Postoperative voiding dysfunction is frequent; of note, in most cases the problem is temporary. When DIE with an ENZIAN classification B is noted intraoperatively and, most of all, when the diameter of the lesion is >3 cm, a higher risk of postoperative voiding dysfunction is to be expected.

Abstract
Objectives Genetic testing rates for hereditary breast and ovarian cancer (HBOC) have steadily increased during the past decades resulting in a growing population of young and healthy mutation carriers. Available data on fertility issues in BRCA mutation carriers is rising but the results remain to some extent still conflicting. We have performed a systematic literature review in order to get an overview concerning the current evidence on fertility issues in BRCA mutation carriers. Data were analyzed critically with the aim to deliver physicians a solid basis for (onco) fertility counseling in women with BRCA mutations. Content We present the latest data on cancer risks in women with HBOC and analyze the influence of cancer treatment and preventive surgery on the reproductive potential. Epidemiological studies on fertility issues in BRCA mutation carriers showed heterogeneous results. However, several authors showed a decreased ovarian reserve with lower Anti-Müllerien hormone (AMH) levels and poorer response to ovarian stimulation in BRCA positive women. The diagnosis of BRCA mutations influences reproductive decision-making. Additionally, the shortened reproductive window and the need to complete family planning early has a significant psychological impact. Summary and Outlook This article highlights the importance of fertility counseling in BRCA mutation carriers. Individual fertility counseling is mandatory. Fertility preservation strategies should be discussed.

Fertility, pregnancy and neonatal outcomes of patients with adenomyosis: a systematic review and meta-analysis. Reprod Biomed Online 2020; 42:185-206.

Abstract
This study aimed to investigate the association of adenomyosis with fertility, pregnancy and neonatal outcomes. An electronic search was conducted using the MEDLINE, PubMed and Cochrane databases up to April 2020. Seventeen observational studies were included. Adenomyosis was significantly associated with a lower clinical pregnancy rate (odds ratio [OR] 0.69; 95% confidence interval [CI] 0.51-0.94) and higher miscarriage rate (OR 2.17; 95% CI 1.25-3.79) after treatment with assisted reproductive technology (ART). The lower clinical pregnancy rate was more significant in the subgroup of patients with short down-regulation protocols. Similar associations were recorded after age adjustment. Adenomyosis was also significantly associated with an increased risk of pre-eclampsia, preterm delivery, Caesarean section, fetal malpresentation, small for gestational age infancy and post-partum haemorrhage, which was confirmed after correction for age and mode of conception. In conclusion, adenomyosis is associated with negative effects on fertility after ART. The potentially protective role of the ultra-long down-regulation protocols needs further evaluation in randomized controlled studies. Adenomyosis is also associated (independently of the mode of conception) with adverse pregnancy and neonatal outcomes. Proper counselling prior to ART and close monitoring of pregnancy in patients with adenomyosis should be recommended.

Abstract
Although unilateral oophorectomies are performed more often than bilateral ones in women of reproductive age, their clinical consequences have been less intensively investigated. Experimental models in animals have shown that compensatory mechanisms occur after a unilateral oophorectomy (UO). This review aims to summarize the available evidence on the biological effects of unilateral oophorectomy on women. Evaluated outcomes include age at onset of menopause, risk of cardiovascular and neurological disease, risk of mortality and fertility outcome after spontaneous conception or in vitro fertilization (IVF). Results were compared with findings reported after bilateral oophorectomy and/or ovarian excision and/or women with intact ovaries. An electronic database search was performed using PubMed and Scopus, followed by a manual search to identify controlled studies that compared women after UO with women with two intact ovaries. In particular, a systematic review of
fertility outcomes after IVF was performed, and the data were summarized in a table. Women who underwent UO had a similar age at menopause and similar clinical pregnancy rate compared to women with two ovaries. However, decreased ovarian reserve affecting the quantity but not the quality of the ovarian pool after IVF was observed in the UO group. Furthermore, an increased risk of neurological disease and even an increased risk of mortality was observed in women with single ovary. These data need to be confirmed by further studies, and a plausible mechanism of action must be identified. At present, patients who undergo UO can be reassured with regard to their reproductive potential and their age at onset of menopause.

Abstract
INTRODUCTION Progestins are commonly prescribed first-line drugs for endometriosis. High rates of non-response and intolerance to these drugs have been previously reported. However, no study to date has investigated the characteristics and comorbidities of patients taking progestins in relation to treatment outcomes, so identifying which patients will respond to or tolerate the treatment is currently impossible. The purpose of this study, therefore, was to identify risk factors for non-response and discontinuation of Dienogest (DNG) in women with endometriosis. MATERIAL AND METHODS This is a retrospective cohort study including women currently taking, or newly prescribed, DNG for endometriosis-associated pain presenting in the Endometriosis Clinic of the University Hospital of Bern between January 2017 and May 2018. Women with initiation of treatment directly after surgery for endometriosis were excluded. For all participants the symptoms and comorbidities were documented. Effectiveness, tolerability and discontinuation of DNG were the primary end points. Univariate and multivariate binary logistic regression models were carried out to identify risk factors for non-response, intolerance and discontinuation of DNG. RESULTS A sufficient or excellent treatment response was reported by 85/125 (68%) participants. Genital bleeding during the DNG treatment was negatively (OR 0.185, 95% CI 0.056-0.610, P = .006) and rASRM endometriosis stages III and IV were positively (OR 3.876, 95% CI 1.202-12.498, P = .023) correlated with the DNG response. When accounting for exclusively pretreatment factors, primary dysmenorrhea (OR 0.236, 95% CI 0.090-0.615, P = .003) and suspicion of adenomyosis (OR 0.347, 95% CI 0.135-0.894, P = .028) were inversely correlated with DNG response, and the latter was also correlated with treatment discontinuation (OR 3.189, 95% CI 1.247-8.153, P = .015). CONCLUSIONS Genital bleeding during the DNG treatment and low rASRM stages are independent risk factors for DNG non-response. Before treatment initiation, primary dysmenorrhea and suspicion of adenomyosis correlate with DNG non-response. The results could assist the clinician first to provide detailed information to women before treatment initiation, second to identify and possibly modify in-therapy factors correlated to treatment effectiveness and lastly to switch treatment on time if needed.

Abstract
Management of Pelvic Inflammatory Disease Abstract. Pelvic inflammatory disease (PID) is a common medical problem, but the diagnosis of PID can be challenging because the clinical manifestations may mimic those of other pelvic and abdominal processes. As PID might cause late complications such as infertility or chronic pelvic pain, it is of prime importance that the diagnosis of PID is made promptly to assure the early onset of an adequate antibiotic therapy. Where uncomplicated PID usually has a favorable course, complicated forms with tubo-ovarian abscess generally require surgical exploration.

Abstract
The autonomic nerves of the lesser pelvis are particularly prone to iatrogenic lesions due to their exposed position during manifold surgical interventions. Nevertheless, the cause of rectal and urinary incontinence or sexual dysfunctions, for example after rectal cancer resection or hysterectomy, remains largely understudied, particularly with regard to the female pelvic autonomic plexuses. This study focused on the macroscopic description of the superior hypogastric plexus, hypogastric nerves, inferior hypogastric plexus, the parasympathetic pelvic splanchnic nerves and the sympathetic fibres. Their arrangement is described in relation to commonly used surgical landmarks such as the sacral promontory, ureters, uterosacral ligaments, uterine and rectal blood vessels. Thirty-one embalmed female pelvises from 20 formalin-fixed and 11 Thiel-fixed cadavers were prepared. In all cases explored, the superior hypogastric plexus was situated anterior to the bifurcation of the abdominal aorta. In 60% of specimens, it reached the sacral promontory, whereas in 40% of specimens, it continued across the pelvic brim until S1. In about 25% of the subjects, we detected an accessory hypogastric nerve, which has not been systematically described so far. It originated medially from the inferior margin of the superior hypogastric plexus and continued medially into the presacral space. The existence of an accessory hypogastric nerve was confirmed during laparoscopy and by histological examination. The inferior hypogastric plexuses formed fan-shaped plexiform structures at the end of both hypogastric nerves, exactly at the junction of the ureter and the posterior wall of the uterine artery at the uterosacral ligament. In addition to the pelvic splanchnic nerves from S2-S4, which joined the inferior hypogastric plexus, 18% of the specimens in the present study revealed an additional pelvic splanchnic nerve originating from the S1 sacral root. In general, form, breadth and alignment of the autonomic nerves displayed large individual variations, which could also have a clinical impact on the postoperative function of the pelvic organs. The study serves as a basis for future investigations on the autonomic innervation of the female pelvic organs.

Abstract
OBJECTIVES Elevated concentrations of numerous molecules have been reported in the peritoneal cavity of women with endometriosis. Until now, no factor proved sufficiently specific to endometriosis. We aimed to investigate several biomarkers in endometriosis and report their association with the menstrual cycle in a large sample size study. METHODS Patients of reproductive age undergoing laparoscopic procedures for benign pathology in the Department of Obstetrics and Gynaecology, University of Bern between 2007 and 2018 were included. Exclusion criteria were the use of hormonal treatment in the three months prior to surgery, patients suffering from other inflammatory diseases, pregnancy, malignancy and surgery performed in an emergency. The concentrations of 13 different biomarkers in the peritoneal fluid (PF) were compared between patients with and without endometriosis both in the proliferative and the secretory cycle phase. RESULTS Out of 1,256 patients in the database, 521 met the inclusion and exclusion criteria. Glycodelin (PP14) and Midkine concentrations were significantly higher in patients with endometriosis compared to controls irrespective of the cycle phase in which the PF was collected. Interleukin-8 (IL-8), regulated on activation normal T cell expressed and secreted (RANTES) and osteoprotegerin (OPG) concentrations were higher in patients with endometriosis only in the proliferative cycle phase. Monocyte chemoattractant protein 1, CCL2 (MCP-1) and Defensin concentrations were higher in patients with endometriosis only in the secretory cycle phase. CONCLUSIONS Certain pathophysiological processes may take place only in the one cycle phase leading to a temporary increase of specific PF biomarkers. Correlation with clinical outcomes is mandatory to establish their potential as prognostic or therapeutic tools in endometriosis.
