Gifu University School of Medicine has introduced a new learning method for medical science, named tutorial system. To assess the efficacy of the method, we conducted a questionnaire survey of students' medical knowledge, attitudes to learning, communication ability, and social behavior. The questionnaire was given to instructors/attending physicians involved in clinical education. Results of the evaluation were compared to those of previous medical students. Our results suggest that the tutorial system in our medical school result in an improvement over the previous curricula.

We made a bibliographic search for Japanese and non-Japanese literature on tuberculosis control programs to study the current public health policies for tuberculosis control in Japan especially in regard to cost-effectiveness. Then, we compared the Japanese, strategies for tuberculosis control with those in other countries including the United States, and those recommended by World Health Organization (WHO). The current trend of tuberculosis incidence in the Japanese community demonstrates major differences from the situation that had prompted installation of tuberculosis control measures several decades ago. The tuberculosis control measures should be targeted to the elderly people (over 65 years old) because of the following three aspects. (1) A continuing decline of tuberculosis in the young Japanese population, particularly children who might attain benefits from BCG immunization; (2) The enhancement of the prevalence among the elderly people who are not covered by a uniform national surveillance strategy; (3) Cost-ineffectiveness of Mass Miniature Radiography (MMR) being used as a means to screen for tuberculosis. The cost-effectiveness issue must be considered more seriously, and the WHO recommendations especially in regard with the DOTS (directly-observed treatment, short course) strategy need to be incorporated more effectively into the national program since the incidence of drug resistant tuberculosis in Japan has been recently increasing. Finally, we propose to limit BCG immunization further and to discontinue annual MMR in the young population, and instead to develop effective strategies of both active and passive case finding in the elderly through public and community health services.

The guide to proper use of methadone in Japan describes the SAG method (a method of stopping all leading opioids and starting methadone). Based on strict evaluation, our palliative care department introduces methadone by adding to the preceding opioid, and then tapering or discontinuation the preceding opioid. This time, we considered the clinical significance of 28 patients who received this method. In 20 of 28 cases (71.4%), methadone reached the maximum dose, and methadone titration could be safely performed without exacerbation of pain or serious adverse events. However, in order for this method to be performed safely, it is necessary to pay attention to the pharmacological properties of methadone, which has a long half-life, and to make a detailed evaluation and drug adjustment of the analgesic effect and adverse events after the introduction of methadone.

Background: Mental assessment for patients in a palliative care unit with no regular psychiatrist tends to depend on subjective judgments by other health professionals. We introduced the 9-item Patient Health Questionnaire (PHQ-9) to screen major depression from patients in a palliative care unit and assessed the usefulness of the questionnaire. Methods: The subjects were all patients who were admitted to a palliative care unit. Each patient was asked to answer the PHQ-9 on admission and then was interviewed by a psychiatrist. When PHQ-9 score was of 10 points and above, the case was judged to be positive for depressive disorder. A psychiatrist diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5). Results: A total of 83 patients were hospitalized between January 2016 and October 2016. 50 patients completed PHQ-9 and psychiatrist’s interview. Nine cases were positive by PHQ-9 and diagnosed as depressive disorder by a psychiatrist. Seven cases were positive by the PHQ-9 but not diagnosed as depressive disorder. Although 34 cases were judged to be negative by the PHQ-9, 2 cases of them were diagnosed as depressive disorder. The sensitivity and specificity of the PHQ-9 were 81.8% and 82.1% respectively. Conclusion: We found that the PHQ-9 was useful screening test for depression even in palliative care settings.
