Objective To investigate the relationship between glucose tolerance change and the coronary artery lesion in the patients with coronary heart disease. Methods One hundred and ninety three patients with coronary artery disease were divided into 3 groups according to WHO(1985) and American Diabetes Association (1997) standard of diabetic diagnoses: (1) normal glucose tolerance (NGT) group 122 cases; (2) impaired glucose tolerance (IGT) group 39 cases; (3) type 2 diabetes mellitus (DM) group 32 cases. All patients were examined by the coronary angiographic semiquantitative (CAG) and 75 g oral glucose tolerance test. Blood glucose, insulin, triglyceride (TG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL C) were determined. The coronary artery changes were analysed by CAG, and the severity of coronary artery stenosis was evaluated according to American Heart Association standard. The risk factors of coronary artery lesion were analysed by pluralism stepwiss regression analysis. Results The coronary multivessel changes and the severity of coronary artery stenosis and calcification were more frequent in IGT group than those in NGT group (66.5% vs 35.1%, 8.9?3.6 vs 6.5?3.9, 6.3?3.6 vs 3.9?4.1 respectively, P

We analyzed the student self-assessment on education in cardiology using a questionnaire.
Subjects: Ninety-six 5th-year students at Saga Medical School who have completed the lectures and bedside teaching were evaluated.
Methods: A questionnaire survey of 14 topics in cardiology was performed at the finish of 3 weeks of bedside teachings. Self-assessment was categorized into 4 grades; 1) completely understood (3 points), 2) almost completely understood (2 points), 3) could be understood (1 point), and 4) could not be understood (0 point). Self-assessment scores were calculated for each topic in cardiology.
Results: Questionnaires were returned by 88 students (91.7%). Self-assessment scores were high for myocardial infarction, angina pectoris, and electrocardiogram reading. Scores were low for primary care, vascular diseases, and pericardial disease. Self-assessment scores did not significantly correlate with the length of lectures but did correlate with the number of admitted patients (r= 0.93) and scores on achievement tests (r= 0.43) in each topic.
Conclusions: Because students observed many patients with myocardial infarction and angina pectoris during bedside teaching, the self-assessment scores were high. Bedside teaching is important for medical students to understand topics in cardiology.

Purpose: The anatomical distribution of perianal warts is associated with patient characteristics such as sexual orientation. The purpose of this study is to confirm this experiential knowledge using a quantitative classification system and analysis and to obtain findings useful for future treatment. Methods: From January 2014 to December 2020, 93 patients with perianal warts presented to our hospital. Patients were analyzed for age, sex, lesion site, and recurrence type, among other factors. The lesion site was divided into skin (S) and anal epithelium (anoderm, A), and the number and degree of each were classified into grades 0 to 3. The higher grade between S and A determines its dominant type, such as type S (e.g., S3A1) and type A (e.g., S0A2). Results: The average age of the patients was 39.6 years, and the percentage of patients who were not married was 54.8%. In all, 95.8% of patients were positive for low-risk human papillomavirus (HPV). Type S accounted for 80.6%, whereas type A accounted for 9.7%. Type A cases were all male and were all presumed to be men who have sex with men (MSM). This indicates that the determination of type A may be highly specific for MSM. The type at the time of recurrence was the same type at the time of the first surgery in almost all cases. Conclusion In cases of perianal warts, it is useful to analyze the lesion by considering the range and grade separately for daily clinical practice on proctologist.
