A new fogging disinfection method was evaluated as a means of disinfecting ward rooms and operating theaters. A temporary room was established where the disinfection effect of fogging was examined. Based on the results, an automatic fogging disinfection unit was developed. This unit was then used in the disinfection of operating theaters, where its safety and effectiveness were examined. To evaluate the results of disinfection, bacterial culture tests were performed on the floor, walls and other areas of the operating theater, and the number of colony forming units was used as an index of effectiveness. Benzalkonium chloride, alkyldiaminoethylglycine, sodium hypochlorite, glutaral and acidic electrolytic water were used for the operating theaters. The average disinfection effect was 90% or better for all disinfectants, except acidic electrolytic water. The newly developed automatic fogging disinfection unit enables safe and effective disinfection, and may be suitable for disinfecting ward rooms and operating theaters.

Continuing medical education for the general practitioners has been activery performed. The former committee for continuing medical education of the Japan Society for Medical Education reported the objectives of continuing medical education for general practitioners. The present committee proposed learning strategies for continuing medical education for general practitioners in accordance with specific behavioral objectives of the curriculum.
It was postulated that appropriate learning strategies are necessary for physicians to provide holistic medical care in their communities, in addition to improving their medical knowledge and skills.
Learning strategies in the curriculum were also coordinated with the continuing medical education system of the Japan Medical Association.

The aim of this study is to clarify the definition and recognition on continuing medical education for administrators (or leaders for residents) of 80 university hospitals and 266 clinical training hospitals as designated by the Ministry of Health and Welfare, using the questionaire consited of 5 main questions, as following:
1) On the curriculum (program) of continuing medical education in their hospitals.
2) On the continuing medical education system of Japan Medical Association.
3) On the continuing medical education activity of the specified academic societies.
4) On guide of continuing medical education for the residents.
5) On definition of continuing medical education.
Answers to a questionaire were returned from 227 institutions (65.6%)
Analyzing the results, present situation of program curricula for continuing medical education in hospitals, participation to continuing medical education system of Japan Medical Association and Academic Societies, and consideration on continuing medical education as a hospital leader were comprehensible.

Background/Aims: In stereomicroscopic sample isolation processing, the cutoff value (≥4 mm) of stereomicroscopically visible white cores indicates high diagnostic sensitivity. We aimed to evaluate endoscopic ultrasound-guided tissue acquisition (EUS-TA) using a simplified stereomicroscopic on-site evaluation of upper gastrointestinal subepithelial lesions (SELs). Methods: In this multicenter prospective trial, we performed EUS-TA using a 22-gauge Franseen needle in 34 participants with SELs derived from the upper gastrointestinal muscularis propria, requiring pathological diagnosis. The presence of stereomicroscopically visible white core (SVWC) in each specimen was assessed using stereomicroscopic on-site evaluation. The primary outcome was EUS-TA’s diagnostic sensitivity with stereomicroscopic on-site evaluation based on the SVWC cutoff value (≥4 mm) for malignant upper gastrointestinal SELs. Results: The total number of punctures was 68; 61 specimens (89.7%) contained stereomicroscopically visible white cores ≥4 mm in size. The final diagnoses were gastrointestinal stromal tumor, leiomyoma, and schwannoma in 76.5%, 14.7%, and 8.8% of the cases, respectively. The sensitivity of EUS-TA with stereomicroscopic on-site evaluation based on the SVWC cutoff value for malignant SELs was 100%. The per-lesion accuracy of histological diagnosis reached the highest level (100%) at the second puncture. Conclusions Stereomicroscopic on-site evaluation showed high diagnostic sensitivity and could be a new method for diagnosing upper gastrointestinal SELs using EUS-TA.
