Objectives: Several reports have shown that Tai Chi Chuan can be an effective way to prevent falls among the elderly. However, an exercise program that can prevent injury during falls has not been reported previously. The judo technique called ukemi is used to prevent injuries. To evaluate whether a judo-based exercise program could prevent falls in the elderly, we had the participants practice ukemi as part of a therapeutic routine. The purpose of this study was to examine the clinical significance of the program and to predict its safety.Methods: From July 2016 to March 2017, we examined 53 individuals who participated in the exercise program. The individuals were divided into high (n=39) and low (n=14) movement ability groups (HMA and LMA groups, respectively), and their physical and psychological functions were evaluated using scores from the Short-Form Health Survey 36. We also collected and analyzed data from questionnaires obtained from 384 patients who participated in the program from July 2016 to July 2019.Results: The HMA group showed a significant increase in the mental component summary scores before and after the exercise program. In the LMA group, physical functioning, social functioning, and physical component summary scores were significantly improved. Of the participants surveyed, 94.8% had a high level of satisfaction, and 93.2% began accepting the exercise as a daily habit. No adverse events were observed during these exercises.Conclusion: This novel exercise program was performed safely, and positive effects were observed, especially in individuals with a low quality of life.

Introduction: We report two cases of surgery under general anesthesia during cancer pain management of patients with methadone therapy. Case 1: A 57-year-old woman was started on methadone for pain from right breast cancer with multiple bone metastases, and right mastectomy was performed during the course of chemotherapy. There was no exacerbation of cancer pain due to methadone withdrawal, although analgesics were used temporarily for wound pain. Case 2: A 76-year-old man was placed on methadone for pain from lung cancer. There was concern that lower limb paralysis would develop from a compression fracture of the lumbar spine that had occurred during the course of treatment. Therefore, decompression and fixation surgery was performed. Ketamine was used to control intraoperative pain exacerbation, and fentanyl was used by continuous injection for re-exacerbation of pain after the patient had awakened from anesthesia. Conclusion: Since methadone is available only by mouth in Japan and the equianalgesic ratio between methadone and other opioids has not been established, caution is needed for perioperative pain control while oral methadone cannot be administered. Thus, pain and palliative care specialists prescribing methadone are expected to play an active role in adequate perioperative pain control.
