1)The Keio University School of Medicine introduced a "white coat ceremony" in 2006 and the taking of an oath written by medical students in 2007 for fourth–year students as part of medical professionalism education just before the start of clinical clerkships.
2)Through activities in 2009, the oath–writing project was highly evaluated by students, and 84% of students felt that Keio University should continue the project.
3)A challenge for the future is finding new ways to encourage more students to participate in the project.

Skeletal muscles are overstretched following limb lengthening procedures. Muscles can adapt to this lengthening by adding new sarcomeres in series. Recent developments in limb lengthening provide adult patients more opportunities to undergo limb lengthening procedures. The purpose of this study was to clarify the difference in muscle adaptation between adult and young groups using a rabbit model of limb lengthening. Five mature (10-43 month old) and 6 immature (3-4 month old) white rabbits underwent tibial osteotomy. After a 1-week lag phase, tibial lengthening was applied at a rate of 1.4 mm/day for 2 weeks. Animals were euthanized after the completion of lengthening. Both hindlimbs were immersed in buffered formalin with the ankle and knee at a right angle. Muscle belly length, muscle fiber bundle length and sarcomere length were measured, and sarcomere number and internal tendon length were calculated in five representative muscles around the lengthened segment. Muscle belly length increased in all the lengthened muscles compared with the corresponding contralateral muscles regardless the group. Aponeurosis length increased significantly in one muscle for the adult group and three muscles for the young group. Sarcomere length tended to be longer or was significantly longer in the lengthened muscles. Serial sarcomere number significantly increased in 3 lengthened muscles in the adult group with a more conspicuous increase in the amount, while this occurred in 2 muscles in the young group with only a tiny increase. The predominant processes of skeletal muscle adaptation to the limb lengthening are sarcomere number addition in muscle fibers for the adult group and elongation of internal tendon for the young group.

　　In recent years, favorable therapeutic outcomes have been reported for arterial injection chemoradiotherapy for tongue cancer. The present case involves an 80-year-old woman in our palliative care department who had high-grade, advanced tongue cancer. Because there was a request for surgery to prevent airway occlusion due to growth of the tumor, she was referred to our department in April 2009. As a treatment policy for controlling tumor growth in high-grade, advanced tongue cancer, arterial injection chemoradiotherapy was carried out through the superficial temporal artery, with a tongue artery catheter in place on both sides. Therapeutic effect was obtained, and it was possible to avoid airway occlusion through tumor regression. Dysphagia and dysphemia were improved, which in turn improved quality of life. In this case, there was an opportunity to carry out multidisciplinary team medicine, including support from the oral care and palliative care teams as part of the process of cancer therapy. Here, we present our findings in this case.

　　Hematopoietic stem cell transplantation (HSCT) involves the administration of anticancer treatment at high doses that exceed the patient’s maximum required dose for total body irradiation, to eliminate malignancy and achieve myeloablation. Hematopoietic stem cells are then transfused to re-establish the lost hematopoietic function. The use of radiation, anticancer drugs, and immunosuppressive drugs can cause adverse events in the oral cavity such as mucositis, bleeding, opportunistic infections, and graft versus host disease. This collaborative report by the departments of hematology and oncology as well as dentistry and oral surgery at our institution discusses the perioperative oral functional management of patients undergoing HSCT. Subjects enrolled were 191 transplantation patients (52 autologous, 139 allogeneic) between 2008 and 2015. The subjects underwent professional tooth cleaning before commencing a transplant conditioning regimen. When the professional oral health care (POHC) treatment was completed, professional tooth cleaning (PTC), professional mechanical tooth cleaning (PMTC), and treatment with a dental drug delivery (3DS) system were provided. This perioperative oral functional management resulted in a decrease in the frequency of oropharyngeal candidiasis from 19.3% to 4.3%. We devised a standardized supportive oral care program from the preoperative period onward to minimize adverse oral events associated with HSCT. The program could effectively improve the quality of life of patients undergoing HSCT.
