Abstract
PURPOSE More than 99% of cervical cancers and up to 40% of vulvar cancers are human papillomavirus (HPV) related. HPV 16 and 18 are the most relevant subtypes. Novel technologies allow the detection of minimal amounts of circulating cell-free HPV DNA (ccfHPV-DNA). The aim of this study was to evaluate ccfHPV-DNA assessed by droplet digital PCR (ddPCR) as a biomarker for molecular therapy monitoring in early, advanced, relapsed and metastatic HPV-driven cervical and vulvar cancer. METHODS Inclusion criteria of the study were histologically proven HPV 16/18-driven cervical and vulvar cancer with first diagnosed disease, newly diagnosed recurrence, or progression of disease. Blood samples were taken pre- and post-therapeutically. Circulating cell-free HPV DNA was quantified using ddPCR and the results were correlated with clinical data. RESULTS The mean copy number of ccfHPV-DNA was 838.6 (± 3089.1) in pretreatment and 2.3 (± 6.4) in post-treatment samples (p < 0.05). The copy number of ccfHPV-DNA increased with higher FIGO stages (p < 0.05), which are commonly used for clinical staging/assessment. Furthermore, we compared the distribution of copy numbers between T-stage 1 versus T-stage 2/3. We could show higher copy number level of ccfHPV-DNA in T-stage 2/3 (p < 0.05). CONCLUSIONS Therapy monitoring with determination of ccfHPV-DNA by ddPCR with a small amount of plasma reflects response to therapy and appears feasible for patients in advanced cancer stages of cervical and vulvar cancer. This promising tool should be examined as marker of therapy monitoring in particular in novel HPV-directed therapies.

The influence of stereoscopic vision on surgical performance in minimal invasive surgery—a substudy of the IDOSP-Study (Influence of 3D- vs. 4 K-Display Systems on Surgical Performance in minimal invasive surgery).

Abstract
Abstract
Purpose
This study is a secondary analysis of the IDOSP trial published in the Annals of Surgery 2020. The aim of this study was to examine the influence of stereo acuity on surgical performance in a laparoscopic training parkour with 3D- versus 4 K-2D-display technique.
Methods
The surgical performance of medical students (MS), non-board-certified surgeons (NBC), and board-certified surgeons (BC) was compared using 3D- versus 4 K-2D-display technique at a training parkour in a randomized cross-over trial. Stereo acuity was tested by TNO and Titmus Stereo tests.
Results
Eighty-nine participants were included in this sub-trial. The median stereo acuity for all participants, measured with the Titmus test, was 25 s arc, with TNO test 30 s arc. Higher quality stereo vision, measured with the Titmus test, correlated significantly with a reduced parkour time (r = 0.26, p = 0.02) and error (r = 0.21, p = 0.048) with the 3D screen. The TNO test did not correlate significantly with parkour performance. There was no statistically significant correlation between parkour time nor error and stereo acuity using the 4 K system (p > 0.457 respectively). Higher age showed a significant correlation with lower stereo acuity measured with TNO (r = 0.21, p = 0.014), but not with the Titmus test (r = − 0.7, p = 0.39). Seven percent of the group “NBC and BC” showed reduced stereo acuity > 120 s arc with the Titmus test and 3% with the TNO test.
Conclusion
High-quality stereo vision is of utmost importance for surgical skills using a 3D-display system. This was most obvious for MS and for tasks that place particularly high demands on hand–eye coordination. The Titmus test was more precise than the TNO test to predict the benefit of a 3D monitor system. Experience and fine motor skills could partly compensate for a poorer stereo acuity.
Trial registration
This trial was registered at clinicaltrials.gov (trial number: NCT03445429, registered February 26, 2018).

Abstract
Background Pyomyoma of the uterus is a rare but severe complication of uterine artery embolization (UAE). This report describes the uterus-preserving management of a case of fast-developing pyomyoma. Screening methods to minimize the risk of this condition are discussed. Case A 46-year-old woman presented with fever, abdominal pain and blood stream infection on the third day after UAE, which had been performed to treat symptomatic uterine myomatosus. Broad-spectrum antibiotics proved inadequate. Magnetic resonance imaging (MRI) showed a possible superinfection of the necrotic myoma. Vaginal smear showed the same organism, a resistant Escherichia coli, as in the blood culture. Because the patient declined hysterectomy, multiple hysteroscopies with removal of necrotic pyomyoma were performed. In addition, an intrauterine gentamicin chain was placed. To our knowledge, this is the first case of pyomyoma immediately after UAE and the first report of successful hysteroscopic treatment in a septic patient. Conclusion In order to reduce the risk of pyomyoma, pre- and postinterventional algorithms should be used. Initial symptoms of pyomyoma can easily be confounded with post embolization syndrome after UAE. Localized gas collection of a necrotic myoma combined with signs of infection can be an indication for pyomyoma. Hysteroscopical resection is an alternative to abdominal surgery e.g. in case of high operative risk/wish of childbreading. Patients with germ detection in vaginal smear should be considered high risk patients for developing a pyomyoma after UAE.
