  • In Raynaud's phenomenon, the authors measured finger blood flow after ice water exposure by analyzing the time activity curve of radionuclide angiography on both hands. The results were as follows: 1) The digital blood flow did not decrease after ice water exposure in normal subjects. 2) In the patients with Raynaud's phenomenon, there were two groups: the one had decreased digital blood flow after cold exposure, and the other had paradoxically increased digital blood flow after cold exposure. 3) There was no difference in the digital blood flow of hand in room temperature between the normal and the patients with reduced digital blood flow after cold exposure, but the digital blood flow of the hand in room temperature was markedly reduced in the patients with paradoxically increased flow after cold exposure. 4) In the static image the difference was not significant in comparision with the dynamic study, because it represents pooling of the blood in the vein rather than flow. 5) After the treatment with nifedipine, the digital blood flow increased. In conclusion, the radionuclide angiography was useful in measuring the digital blood flow in Raynaud's phenomenon, and further studies with various drugs is expected.

  • Digital polysomnography was developed to overcome the limitations of Rechtschaffen and Kales rule and to compensate the shortcomings of paper polysomnography. It enables easy access to and secure preservation of sleep records, and provides various displays of sleep data to enhance efficiency of visual scoring of sleep records. Rechtschaffen and Kales rule had been criticized for its ambiguity and lack of considerations in spatial information of EEG. As sleep records are acquired and processed in digital mode, they can be analyzed at microscopic and macroscopic levels. Digital analysis of sleep records provides the basis for development of new sleep measures. Sleep staging in digital polysomnography is based on the various analyses of EEG. Sleep apnea, hypopnea and periodic limb movement are detected automatically by digital analysis of respiratory signals and leg EMG. Digital polysomnography plays a complementary role to visual scoring and compensates the limitations of paper polysomnography. Digital polysomnography, including acquisition, processing and analysis of sleep records in digital mode, can be a great help in the development of sleep medicine, enabling the development of new sleep measures and the exchange of sleep records between sleep laboratories.

  • Objectives: The medical field is rapidly evolving with AI and digital technologies like AI-based X-ray analysis and digital therapeutics gaining approval. Telemedicine is becoming prominent, and medical schools are adapting by integrating AI education. Pusan National University leads a talent training project for AI in health. Korean Medicine is incorporating AI with diagnostic systems and chatbots. However, there's a lack of research on education awareness in Korean Medicine Colleges. The study aims to assess opinions on integrating AI, digital therapeutics, and DNA test into the Korean medicine college curriculum for improved education. Methods: We selected appropriate four specific areas: artificial intelligence in medicine, digital therapeutics, DNA test, and telemedicine. The questionnaire developed for this study underwent expert evaluation and was subsequently administered to registered KMDs of the Association of Korean Medicine, as well as students from 12 Korean Medicine universities. The survey was designed to analyze the awareness and perceived importance of the 4 areas. Results: Both KMDs and Korean medicine students exhibited comparable awareness levels across the four objectives. Notably, both groups identified a high educational necessity and importance of artificial intelligence in medicine for clinical settings. Statistically significant differences were observed between KMDs and students in their perspectives on the importance of telemedicine and DNA test in the Korean medicine field, the educational necessity of DNA test within Korean medicine universities, and the need for comprehension of regulations related to digital therapeutics. Conclusion: The survey of Korean medicine professionals and students underscores a strong understanding of key areas such as Telemedicine, medical AI, DNA test, and digital therapeutics. Medical AI is identified as crucial for future education. There's a consensus on the need for curriculum changes in Korean medicine schools, particularly in adapting to evolving healthcare trends. The focus should be on practical clinical application, with a call for additional research to better integrate student and practitioner perspectives in future curriculum reform discussions.

  • Purpose: The vessels of peripheral nerves have been extensively studied since Breidenbach used vascularizd nerve grafts. Tayor and Pinel studied the course and distribution of the vessels of peripheral nerves. However, the vessels of digital nerves are still not well known. The objective of this study was to prove vessels of digital nerves and to investigate the pathway of that. Materials and Methods: 36 patients and 2 fresh human cadavers were studied under the microscope and histologic sections under the light microscope.. Results: We found that digital nerves had own arterioles and venules as well as peripheral nerves. This small vessels of digital nerves paralleled the digital nerves or run in a spiral. Digital nerves were abundantly vascularized throught their length by a succession of vessels and by their repeated divisions and anastomoses. Conclusion: The clinical implications of this results can be discussed in relation to the dissection of nerves, the possibility of vasculized nerve grafts.
