The patients of vibration diseases were treated by balneotherapy. The effects of balneotherapy were judged from the ameliorating degree of subjective symptoms such as sensation of coldness, sensation of numbness, pains of physical signs for which peripheral functions were examined by cold water-dipping test, vibration sensation test, squeeze dynamometry, tapping test and thermography. There were no differences between balneotherapy for 1.5 months and for 3 months. This suggests that balneotherapy for 1-1.5 months is sufficient for treating the patients of vibration diseases.
Recently developed oxothermic packs (temperature 47-48°C, Duration of heat 2-3 hours) were used in combination with balneotherapy to warm the affected area. The application of the exothermic pack in combination with balneotherapy ameliorated markedly subjective symptoms and physical signs, comparing with balneotherapy alone.
A sound-cold loading apparatus was devised for physical examination of vibration diseases. A specific pulse curve was obtained in patients complaining of pains after using chain-saw.

　Medical education has been experiencing a marked paradigm shift. In the US academic health care environment, educational activities are weighed and considered important factors for promotion. Therefore, clinician-educators can flourish in any specialty field. The Harvard Macy Institute has offered longitudinal programs to foster the growth and development of leaders and innovators in healthcare professionals' education across the nation & world for more than 20 years since its foundation in 1994. A three-day intensive course for residents and fellows-in-training was started in 2012 to meet the need to train future faculty leaders. This program is entitled; "Program for Post-Graduate Trainees: Future Academic Clinician-Educators."

　Recently, the author had the opportunity to participate in this program held at the Massachusetts General Hospital Institute for Health Professions in Boston from December 6th to 8th, 2014. In this article, the author discusses his perspectives on medical education and how to build a career as a clinician-educator, as he introduces the program.
