Conclusion The method comparison using conventional statistical approaches had limits due to the semi-quantitative value of the test. Log-transformed interval scale values for comparison were useful for interpretation of method comparison datasets. This alternative statistical approach could contribute to a more accurate comparison between assays and standardization of ABT testing.Background Primary vaginal carcinoma is a rare gynaecological tumour representing 1%-3% of all gynaecologic cancers. Several studies report increased vaginal cancer risk associated with genital prolapse following the occurrence of inflammatory lesions or decubitus ulcers. Case We report the rare case of an 82-year-old woman with primary squamous cell carcinoma arising from vaginal wall prolapse. Vaginal carcinoma was suspected during gynaecological examination for vulvar bleeding. A wide local excision was performed and pathologic examination revealed a primary squamous cell carcinoma of the vagina. Conclusion Persistent genital prolapse may be at risk for vaginal carcinoma, and cytological and a colposcopic assessments are essential to identify patients who require diagnostic biopsy.Bioethics education is a central element in the biotechnology curriculum. Re-imagining distance learning, virtual reality (VR) is taking student involvement to the next level of interaction, offering a real classroom experience and a new way to gain ethical reasoning skills. Here, we explore a new paradigm for bioethics education that involves VR.Objective The immune checkpoint inhibitor Nivolumab was approved for the treatment of platinum-refractory head and neck squamous cell carcinoma (SCC), expanding the treatment options for recurrent or advanced head and neck SCC. However, since temporal bone squamous cell carcinoma (TB-SCC) is very rare cancer, the effectiveness of Nivolumab remains unclear. We investigated the effects of Nivolumab for TB-SCC. Method Chart information was collected for all patients who underwent the first administration of Nivolumab for recurrent or residual TB-SCC in our hospital between September 2017 and December 2019. Tumor staging followed the modified Pittsburgh classification. Changes in the tumor burden and survival outcome were examined. Results We examined 9 patients with recurrent or residual TB-SCC who started administration of Nivolumab. In these cases, recurrent or residual SCC was observed after chemotherapy and/or chemoradiotherapy including platinum. The duration of Nivolumab was 2-54 weeks (median 20.0 weeks). The evaluation of the therapeutic effect according to the RECIST method showed partial response in 1 case, stable disease in 2 cases, progressive disease in 4 cases, and size unevaluated in 2 case. Although the number of cases was small, comparing with 5 cases without Nivolumab, these cases showed longer overall survival (1-year OS 33.3% vs 20.0%). Conclusion We used Nivolumab as palliative chemotherapy in 9 patients with recurrent/residual TB-SCC, and we were able to obtain a certain therapeutic effect on TB-SCC as well as other head and neck SCC.Background Patients with psychological distress are likely to have poorer short-term functional outcomes after total knee arthroplasty. However, the influence of psychological distress on the outcomes of total hip arthroplasty (THA) is relatively understudied. Previous studies also had short follow-ups of 1 year or less. We examined the influence of psychological distress on patient-reported outcomes and satisfaction, and analyzed the change in mental health after THA at a minimum of 2 years. Methods Prospectively collected data of 1384 patients undergoing primary THA in 2001-2015 were reviewed. Patients were assessed using the Oxford Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index, and 36-item Short-Form health survey Physical Component Summary and Mental Component Score (MCS). Patients were stratified into those with psychological distress (MCS less t
