We aim to develop a softness sensor to evaluate cervical canal during internal examination. In this paper, we designed a soft wearable sensor that does not impair the tactile sensation of the fingertip, and evaluated the effect of the presence of tactile sensation on the pressing angle during the internal examination. The sensor covers the fingertip and has a hole on the fingertip to touch the target tissue. The experimental result showed that participants using the sensor with a hole successfully controlled the pressing angle. In addition, we proposed an improvement of the sensor on the basis of the result.

In this paper, we used a flexible wearable tactile sensor that utilizes acoustic reflection, and investigated hardness estimation based on the sensor output using human spontaneous haptic exploratory motion. Machine learning methods with support vector machine and convolutional neural networks were adopted to the acquired sensor output for the identification of hardness of cervical models. As a result, the correct answer rates of both learning models were 100 ％ for the soft model and about 80 ％ for the hard and medium models.

Introduction: Ovarian auto-amputation is extremely rare and is most commonly attributed to chronic adnexal torsion and subsequent devascularization that precipitate infarction and necrosis. We describe a woman (Jehovah's witness) who presented with an inflamed abdominal cyst, which was diagnosed as an auto-amputated endometrial ovarian cyst, following laparoscopic surgery.Case presentation: A 45-year-old Jehovah's witness was referred to our hospital with acute abdominal pain. She had complained of dysmenorrhea prior to referral. Laboratory data revealed evidence of severe inflammation (white blood cell count 12400 cells/μL, C-reactive protein 17.4 mg/dL). MRI revealed a cystic pelvic tumor with features of a benign ovarian cyst. She received intravenous antibiotics with resolution of inflammation following this conservative therapy after which we performed laparoscopic surgery for removal of the pelvic mass. Intraoperatively, we performed careful adhesiolysis followed by meticulous exploration of the pelvic cavity. We performed cystectomy and left adnexectomy with insertion of multiple drains into the peritoneal cavity.Discussion: Based on the laparoscopic and histopathological findings, the patient was diagnosed with chemical panperitonitis associated with a wandering ovarian endometrial cyst.Conclusion: We report successful but significantly challenging laparoscopic intervention for a wandering ovarian endometrial cyst in a woman with chemical peritonitis.
