D4 Flavor Symmetry for Neutrino Masses and Mixing

We present the $D_4\times Z_2$ flavor symmetry, which is different from the previous work by Grimus and Lavoura. Our model reduces to the standard model in the low energy and there is no FCNC at the tree level. Putting the experimental data, parameters are fixed, and then the implication of our model is discussed. The condition to realize the tri-bimaximal mixing is presented. The possibility for stringy realization of our model is also discussed.Comment: 10 pages, 1 figur

Introduction to Digital Fujikawa –History of Medicine in Japan–

[The 2019 International Image Interoperability Framework (IIIF) Conference] 2019/06/24-28, Göttingen, GermanyThe Fujikawa collection is a collection of old medical books that had been collected by Dr. Yu Fujikawa (1865-1940). Books in the collection are stored in multiple institutions including Kyoto University, Keio University, and the University of Tokyo. This presentation describes our project “Digital Fujikawa –History of Medicine in Japan–”, which has been jointly launched by Kyoto University Library Network and Keio University Media Center. The project intends to contribute to the development of the research in the history of medicine in Japan by providing the comprehensive view of the Fujikawa Collection that has been physically distributed over different institutions. On September 28, 2018, we launched a website (http://www.kulib.kyoto-u.ac.jp/rdl/digital_fujikawa/en/) that virtually brings together the holdings of different institutions in one place using IIIF protocols. As of February 22, 2019, the website delivers 5, 333 titles from three institutions. In the presentation, we look back on different implementations that we examined during the development of the website. In addition, we report the influence of the project on usage statistics of titles. In the future, we increase digital images available and participating institutions and develop new functions, in order to progress this project from the current trial phase to a full-scale phase by the end of academic year 2020/2021. Acknowledgements: the digitization of the Fujikawa collections has been supported by the following projects: (1) Project to build an international collaborative research network for pre-modern Japanese texts (NIJL-NW project) by the National Institute of Japanese Literature, (2) Grants for functional enhancements by the Ministry of Education, Culture, Sports, Science and Technology, (3) Kyoto University Open Access Promotion Project, and (4) Keio University Media Center (ordinary expenses)

子宮内膜症性腸閉塞に対する経肛門的イレウスチューブの有用性

One of the causative diseases of intestinal obstruction in young women is bowel endometriosis. During the course of ectopic endometriosis, it is estimated that about １０％ of patients develop bowel endometriosis. The first step in treatment is drug therapy. In cases of bowel endometriosis of the colon or rectum leading to intestinal obstruction, laparotomy is often required. A ４７-year-old woman with a history of endometriosis was undergoing drug therapy. She developed abdominal pain and nausea, and was diagnosed with septic shock and fecal ileus. A transanal drainage tube was inserted for decompression. The patient’s general condition improved, and a laparoscopic low anterior resection was performed on the ２３rd day. The patient was discharged on the １０th postoperative day without any postoperative problems. This case suggests that even in the case of septic shock caused by rectal stricture due to intestinal endometriosis, initial treatment with transanal decompression may stabilize the general condition, and may be superior in cosmetic change

Primary aldosteronism: A Japanese perspective

Primary aldosteronism (PA) is the most common cause of secondary hypertension, accounting for 10% of all hypertension. Far from being benign, hypertension due to PA is associated with high cardiovascular morbidity and mortality. However, PA is still underdiagnosed in general practice. Recent reports strongly recommend that identifying patients with PA is cost-beneficial based on improved cardiovascular outcomes afforded by specific surgical and medical treatment. This review provides an update of PA including controversial aspects of diagnosis and treatment

重傷外傷の認識が遅れ救急外来で緊急開腹術を行った１例

An８１-year-old man fell down and bruised his left abdomen. After a while the back pain got worse, and he admitted to the Emergency Department. At hospitals admission, several signs of shock were observed, and contrast-enhanced CT revealed a splenic injury. However, it took an hour and a half to diagnose and convene the trauma team because of the lack of information shared among medical staffs and the delay of the recognition as a severe traumatic injury. Since there was no available operation room at the time, nor there wasn’t time to transfer to another hospital, he was forced to undergo emergency open splenectomy at the Emergency Department. That decision saved his life as a result. In ２００２, it revealed that the deaths of about ４０％ of expired trauma patients who arrived at emergency centers were probably preventable. Since then, much progress has been made in establishing and generalizing the trauma care and evaluation guidelines. Our hospital is also making progress in organizing a trauma team and the massive transfusion protocol. However, even if they are well maintained, we won’t be able to decrease the number of preventable trauma deaths（PTD）unless we diagnose it. Improving clinical management as well as making efforts on teamwork, leads to a rapid definitive care in trauma patients
