Introduction: Few studies have examined neuropathological changes such as the degenerative necrosis and demyelination of spinal nerve cells accompanying intrathecal administration of opioids (ITO) to relieve refractory cancer pain. Previous studies have produced conflicting results as to whether or not ITO causes nerve tissue damage. The current study neuropathologically investigated autopsy specimens from patients who received ITO. Methods: Subjects were 7 patients who received continuous intrathecal analgesia and who were later autopsied (4 males, 3 females). Six patients were administered morphine and bupivacaine while 1 patient was administered fentanyl and bupivacaine. The duration of administration ranged from 6-345 days. Results: Two patients who received long-term administration of morphine were found to have severe necrotic degeneration and gliosis of spinal neurons and demyelination in the dorsal horn and dorsal roots. However, neuropathological changes were not noted in Patient 4, who was briefly administered morphine, or in the patient who was administered fentanyl. Conclusion: The total dose of morphine used for ITO and the duration of its administration were suggested to be related to the extent of nerve tissue damage. Thus, nerve tissue damage due to ITO might be primarily associated with morphine.

The patient was a 63-years-old female with early gastric cancer in her upper stomach. Widely spreading on the mucous membrane, the cancer was too big to remove by endoscopical mucosal resection, although she wanted minimal invasive treatment. Therefore, we adopted total gastrectomy with hand-assisted laparoscopic surgery (HALS) after obtaining “informed consent” from her. Five small skin-incisions were necessary to perform it-one 7cm' for hand-port and four 1.2cm' for trocars.
The dissection was started from greater omentum and proceeded counterclockwise to remove primary lymphnodes. The abdominal esophagus and the duodenum were devided with a single or double application of Endo GIA stapler (linear stapler). All these steps were accomplished safely and securely with the effective support of the left hand of the operator. After extraction of the whole stomach through the 7cm-incision, Roux-en Y reconstruction was performed laparoscopically (esophago-jejunostomy) followed by hand sewing through the 7cm-incision (jejuno-jejunostomy). The anvil of 21mm circular stapler (EEA) was inserted orally in order to anastomose the esophagus to the jejunum. The patient had acceptable results intra-operatively as well as postoperatively by HALS total gastrectomy, which had been considered to be very hard to perform up to present time.

The promotion of clinical research in Japan requires the establishment of a formal and systematic education and training program for clinicians to ensure they become effective clinician investigators. The first of its kind in Japan, a formal 1-year masters-degree-level training program (MCR course) was started at Kyoto University School of Medicine and Public Health. The first 28 students graduated in 2008, with most returning to their original clinical institutions.
1) As follow-up, we conducted a self-administered questionnaire survey of all 28 graduates (response rate, 86%) concerning the current status of clinical research and problems encountered at their institutions.
2) Almost 40% of respondents (n=24) reported "no time" or "no research collaborators" for clinical research.
3) Twenty respondents (83%) have attempted to promote clinical research at their hospital or workplace, but only 1 has received institutional support.
4) Over half of the respondents (54%) would like to be working in both clinical research and clinical practice at their hospital in the future (10-year timescale). Forty-two percent of respondents had a concrete image of the clinical researcher's career path.
5) Although open to improvement, the MCR program presents a concrete model for the education of clinical researchers. These findings suggest that promoting the conduct of clinical research requires the implementation of a support system and adjustment of personal and physical infrastructure.

Students in all years, including those in lower years, were prohibited from coming to campus because of COVID-19, which began to spread in January 2020. However, we believed that a hospital tour and observership would be important practical training for first and second year medical students as part of the early exposure program, which aims to increase student motivation. Thus, we decided to conduct a virtual hospital tour and a virtual observation of medical doctors’ work. We used Zoom to conduct a virtual hospital tour for first-year students in June, and a virtual observation of physicians’ work for second-year students in December. Although this offered less of an opportunity to experience the reality of the clinic, there have been benefits in terms of increased learning content, fairness of learning opportunities delivered, and the promotion of independent learning. With regard to a “Hospital Tour” and the “Observation of Medical Doctors’ Work” , we believe that hybrid forms, which are able to skillfully combine the strengths of the two methods, would be effective.
