The eight subjective symptoms (shoulder stiffness, lumbago, urinary frequency at night, numbness of extremities, shortness of breath, sleep disturbance, dizziness and abdominal distension) were checked at the screening of circulatory diseases performed in a rural district in Ehime prefecture.
1. The complaint rates of the eight subjective symptoms were higher in female than those in male. The influence of aging was observed in urinary frequency at night and sleep disturbance. The higher complaint rates in the agricultural workers were not evident in the subjective symptoms except lumbago.
2. Factor analysis indicated that the eight subjective symptoms were constituted by (1) fatigue of circulatory system, (2) fatigue of musculoskeletal system and (3) aging effect.
3. The higher complaint rates were observed in these diagnosed as circulatory diseases, musculoskeletal diseases or gynecological diseases. The correlations between the eight subjective symptoms and the laboratory findings were not apparent. The result of path analysis indicated that the eight subjective symptoms were independently referable to the presence of illness.
4. The eight subjective symtoms were considered considered to be to evaluate health status of inhabitants in rural district.

We reviewed the clinical course of 127 patients who underwent treatment for atherosclerotic disease between June 1993 and January 2001. There were 108 men and 19 women. The ages ranged from 49 to 88 years with a median age of 71.2 at the time of the first operation. Major risk factors included ischemic heart disease (21%) and diabetes mellitus (20%). Ninety-five percent of the patients were followed successfully and the follow-up period ranged from 0 to 90 months with a mean of 33 months. Two patients died perioperatively due to myocardial infarction. There were 29 late deaths. The overall actuarial survival rate was 69.7% at 5 years. The 5-year actuarial survival rate and the mean survival time for men and women were 71.6%, 66.1 months and 62.3%, 58.9 months. The 5-year late survival rate and the mean survival time for patients with and without ischemic heart disease were 57.0%, 57.4 months and 74.2%, 68.5 months. The differences were not statistically significant. The 5-year late survival rate and the mean survival time for patients with and without diabetes mellitus were 65.5%, 59.1 months and 70.9%, 67.4 months. The differences were not statistically significant. Amputation was performed in 7 patients, the actuarial survival rate at 1 year and the mean survival time were 42.9%, 7.1 months for patients with amputation, and 93.0%, 69.5 months without amputation (p<0.01).

From November 1976 to December 1991, we performed extra anatomic bypass procedures (EAB) in 100 cases with aortoiliac occlusive disease. The operative procedures included 26 axillo-femoral bypasses (Ax-F), 27 femoro-femoral bypasses (F-F) and 47 aorto-femoro-femoral bypasses (Ao-F-F). The average age was 75.8 years in Ax-F and 73.8 years in F-F. These were significantly higher than that of Ao-F-F (70.8 years). In addition, the rate of limb salvage in Ax-F was 85%, and this group had more critical cases than the other two groups. The cumulative primary patency rate and survival rate at 5 years were 64.4%, 20.8% (Ax-F), 65.9%, 51.1% (F-F) and 96.5%, 70.4% (Ao-F-F) respectively. The late results of Ao-F-F were comparable to direct aorto-femoral bypass procedures performed in our institution during the same period. On the contrary, the results of Ax-F and F-F were discouraging. We suggest that EAB should be selected for high risk, limb salvage cases and in particular, Ax-F and F-F should be limited to patients with nonphysical acting. We are opposed to appealing for an extended indications of EAB and it should not be regarded simply as a low-risk substitute for aorto-femoral bypass.

Abstract:

 This study examined the ability of medical students to self-assess basic clinical competence and learning strategies including simulation-based medical education for sixth-year medical students (n=903) at nine universities in Japan. About 40% of 27 procedures to achieve clinical skills in a model curriculum were taught using simulators with or without clinical training in hospitals. We noted that significant numbers of procedures were not practiced through any learning strategies. Higher self-assessment scores were observed among students in 4 schools who had more frequent learning opportunities through simulation-based education than among those with less frequent opportunities in 5 schools.
