Abstract
PURPOSE The purpose of this survey was to assess medical students' opinions about online learning programs and their preferences for specific teaching formats during COVID 19 pandemic. METHODS Between May and July 2020, medical students who took an online gynecology and obstetrics course were asked to fill in a questionnaire anonymously. The questionnaire solicited their opinions about the course, the teaching formats used (online lectures, video tutorials featuring real patient scenarios, and online practical skills training), and digital learning in general. RESULTS Of 103 students, 98 (95%) submitted questionnaires that were included in the analysis. 84 (86%) students had no problem with the online course and 70 (72%) desired more online teaching in the future. 37 (38%) respondents preferred online to traditional lectures. 72 (74%) students missed learning with real patients. All digital teaching formats received good and excellent ratings from > 80% of the students. CONCLUSION The survey results show medical students' broad acceptance of the online course during COVID 19 pandemic and indicates that digital learning options can partially replace conventional face-to-face teaching. For content taught by lecture, online teaching might be an alternative or complement to traditional education. However, bedside-teaching remains a key pillar of medical education.

Abstract
PURPOSE Vaginal cuff dehiscence (VCD) is one of the major surgical complications following hysterectomy with data on incidence rates varying largely and studies assessing risk factors being sparse with contradictive results. The aim of this study was to assess the incidence rate of and risk factors for VCD in a homogenous cohort of women treated for benign uterine pathologies via total laparoscopic hysterectomy (TLH) with standardized follow-up. METHODS All patients undergoing TLH at the Department of Gynecology and Obstetrics, Saarland University Hospital between November 2010 and February 2019 were retrospectively identified from a prospectively maintained service database. RESULTS VCD occurred in 18 (2.9%) of 617 patients included. In univariate and multivariate analyses, a lower level of surgeon laparoscopic expertise (odds ratio 3.19, 95% confidence interval (CI) 1.0-9.38; p = 0.03) and lower weight of removed uterus (odds ratio 0.99, 95% CI 0.98-0.99; p = 0.02) were associated positively with the risk of VCD. CONCLUSION In this homogenous cohort undergoing TLH, laparoscopic expertise and uterine weight influenced the risk of postoperative VCD. These findings might help to further reduce the rate of this complication.

Abstract
Background: To determine German obstetricians' self-perceived experience with vacuum and forceps deliveries.Patients and methods: Using a web-based survey, German obstetricians were invited to participate in a survey. This survey was approved by the German society of obstetrics and gynecology.Results: Surveys of 635 obstetricians were received. All obstetricians reported performing significantly less forceps than vacuum deliveries. Almost all obstetricians want to perform more delivery, which indicates the willingness to learn both. More obstetricians felt confident to perform vacuum than forceps. In a similar obstetrical indication, most of the obstetricians would prefer to perform a vacuum assisted delivery. The majority of the obstetricians wished to receive more training in vaginal operative deliveries.Conclusion: Most of the German obstetricians prefer to use vacuum-assisted vaginal deliveries and feel less confident to perform forceps deliveries. Standardized training to improve the quality of care is recommended.

Abstract
Objective: Conisation of the cervix is one of the most common surgical procedures in gynaecology. Nevertheless, surgical expertise is required because if the cone is too small, the oncological risk increases and if the cone is too large, the obstetric risk increases. The aim of this prospective study was to investigate the suitability of an in-house conisation simulator for teaching medical students the practical performance of conisation. Material and Methods: Following a demonstration, students performed a loop conisation with a target depth of 8-10 mm using the simulator. Cone biopsy dimensions were analysed and a loop electrosurgical excision procedure (LEEP) score was calculated. The students were surveyed using a questionnaire of 12 items with five possible responses for each in order to investigate the suitability and realism of the teaching experience. Results: Eighty-nine students participated in the course. The median (range) cone depth was 8 (3-25) mm with a standard deviation of 3.3 mm. The observed LEEP score amounted to 1.5. The questionnaire was answered by 88 students and completed by 86. Survey results showed the course was consistently rated as positive, especially towards the increase in practical skills. The questionnaire item producing the highest score was “I enjoyed the course” while the statement “I have gained enough self-confidence for the application of high-frequency surgery” received the lowest approval score. Students considered the course to be realistic and a helpful teaching exercise. Conclusion: Practical surgery exercises on the surgical simulator were received positively. Simulation training could be extended to other gynaecological operations and to other medical subjects.

Abstract
PURPOSE In previous studies, we have shown that SEC62 has an essential function in cell migration, epithelial-to-mesenchymal transition, and endoplasmic reticulum stress tolerance of cancer cells. SEC62 expression correlated with distant and lymph node metastasis and poor outcome in different cancer entities. In this initial study, we investigated SEC62 expression and its possible role as a prognostic and predictive biomarker in breast cancer (BC). METHODS Formalin-fixed, paraffin-embedded tissue samples of 53 BC patients were analyzed by immunohistochemistry. The immunoreactive score (IRS) according to Remmele and Stegner was evaluated and correlated with clinico-pathological findings and overall survival (OS). RESULTS We found increased SEC62 protein levels in tumor tissue compared to tumor-free tissue samples from the same patients. Tumors with high SEC62 expression (IRS > 8), or containing isolated cells with high SEC62 staining intensity, independent of the IRS, had more frequently distant metastases (48.4% vs. 18.2%; p = 0.024 and 47.4 vs. 6.7%; p = 0.005, respectively). Overall survival was significantly worse in BC patients with high SEC62 expression (SEC62 IRS > 8) (54.8% vs. 81.8%; p = 0.011) and in cases with isolated high-intensity SEC62 staining cells independently of SEC62 IRS (55.3% vs 93.3%; p = 0.024). CONCLUSIONS We are the first to describe the SEC62 expression and its correlation to clinicopathological parameters in mammary carcinoma. Our results suggest that SEC62 expression may serve as a prognostic marker for patients with invasive ductal breast cancer.

Abstract
PURPOSE We address the impact of applying loop electrosurgical excision procedure (LEEP) under direct colposcopic vision teaching to our undergraduates using a self-developed simulation model and a standardized assessment to evaluate the progress of learning. METHODS The undergraduate teaching module was composed of a theoretical course on cervical dysplasia, colposcopy, electrosurgery and excisional procedures of the uterine cervix. This was followed by hands-on practical rounds. During the hands-on practice the students performed five "type 1" LEEP under direct colposcopic vision on the self-developed simulator. Based on specimen fragmentation and excision accuracy a score system was established. The students were asked to answer a course evaluation questionnaire. RESULTS The accuracy of the excisions showed a statistically significant improvement during the five training procedures (excision depth 7.34 ± 1.60-8.54 ± 1.67 mm, p = 0.0041; deviation from target cone thickness 0.88 ± 1.16-0.13 ± 0.94 mm, p = 0.0116). The fragmentation of the conus decreased (2.57 ± 1.26-1.29 ± 0.60 pieces, p < 0.0001). All this led to a general improvement of the LEEP score (2.59 ± 1.93-0.84 ± 1.03, p = 0.001). The student's questionnaire revealed a subjective satisfaction and improvement of their knowledge in pathomechanism, diagnosis and therapy of cervical pathologies. CONCLUSION Undergraduate surgical training, in cervical excisional procedure, is a successful method in improving the students' perception and management of cervical pathologies.

Abstract
PURPOSE The aim of this study was to analyze the diagnostic performance of a newly established immunocytochemical dual-staining protocol for the simultaneous expression of SEC62 and Ki67 in vulvar liquid-based cytology specimens for the identification of vulvar intraepithelial neoplasia (VIN) and vulvar cancer. In addition, we investigated the p16/Ki67 dual stain, which has already been established in cervical cytology. MATERIALS AND METHODS For this pilot study, residual material from liquid-based cytology was collected retrospectively from 45 women. The presence of one or more double-immunoreactive cells was considered as a positive test result for Sec62/Ki67 and p16/Ki67 dual staining. The test results were correlated with the course of histology. RESULTS All cases of VIN and vulvar cancer were Sec62/Ki67 and p16/Ki67 dual-stain positive, and normal and low-grade squamous intraepithelial lesions were all negative. The sensitivity of cytology for VIN + cases was 100% (22/22), whereas punch biopsy classified one case of vulvar carcinoma as inflammation. All cases with high-intensity (grades 3 and 4) Sec62 staining in Sec62/Ki67-positive cases were carcinomas. CONCLUSIONS The results of this study demonstrate that Sec62/Ki67 and p16 Ki67 dual-staining cytology could be a promising adjunctive diagnostic tool for VIN and squamous cell carcinoma, in addition to standard histology.

Abstract
PURPOSE In the previous studies, we demonstrated that Sec62 is essential for tumor cell migration, epithelial-to-mesenchymal transition, and intracellular stress tolerance. An increase in Sec62 expression correlated with an increase in cervical dysplasia severity in liquid-based cytology specimens. Ki67 is an established proliferation marker. Thus, in this study, we examined a method of Sec62/Ki67 dual staining for the detection of high-grade dysplasia and cancer in cervical liquid-based cytology specimens. METHODS Sec62/Ki67 dual staining was performed on 100 cervical liquid-based cytology specimens. The staining results were correlated with cytological, immunocytological (p16/Ki67), colposcopic, and histological findings. RESULTS All 56 (n = 56, 100%) cases of cervical intraepithelial neoplasia grade 3 and cervical cancer (CIN3+ lesions) were positive for Sec62/Ki67 staining, while low-grade lesions and normal cells were negative. Sec62/Ki67 staining was highly sensitive and specific for the detection of CIN2+ and CIN3+ lesions (94.37%; 100% and 100%; 84.09%, respectively). CONCLUSIONS Sec62/Ki67 dual-staining immunocytochemistry is a promising cytological tool for interpreting high-grade squamous lesions in cytological specimens and for assessing the risk of progression to cancer.
