The purpose of this study was to measure the effectiveness of RPE on exercise intensity for senior citizens. A maximum workload test was administered with the use of a bicycle ergometer on older male and female subjects. The results of our study can be summarized as follows:
1. Two trials were performed on separate days. A high correlation coefficient for the first trial and the second trial was found. The reliability for the male group was r=0.76 (p<0.01) and that for the female group r=0.90 (p<0.01) .
2. A correlation range of r=0.55-0.79 (p (0.01) was found for RPE and physiological exercise intensity (which includes oxygen intake and heart rate) . A higher result was found when the relative value was used in the analysis of the oxygen intake and the heart rate instead of the absolute value.
3. Significant correlation coefficients of r=0.63-0.64 (p<0.01) were found for RPE and the work load in terms of watt units.
4. The majority of the physiological variables were statistically determined ; however, there were no correlations between RPE and systolic blood pressure.
In conclusion, based on our study, we have found that RPE and HR ; RPE and %Vo₂max: RPE and watts grouped individually had a high correlation for effectiveness. The only exception in our study was the RPE and the blood pressure group because no correlation was found overall. Therefore, the overall effectiveness of RPE was proven to be quite sensitive even for senior citizens, and as a result RPE can be utilized when exercise is prescribed for evaluatory measurement in senior citizens.

1) To become physicians who care for patients as human beings, medical students must know about child welfare. A serious problem in the fields of medicine and welfare is child abuse. Collaboration is needed to support children and families, but many challenges exist.
2) The goal of our Multidisciplinary Team Workshop, which started in 2006 and targets students in a wide range of fields, is to educate future practitioners about the necessity of multidisciplinary collaboration.
3) More than 80% of the participating students felt the workshop was useful, and the participation of medical students increased the significance of the workshop for students from other disciplines.

Three patients, who received infrarenal aorto-iliac bifurcation grafts, complained of flaccid and insensible feeling on lower extremities immediatedly after surgery. These symptoms were supposed due, in two cases, to spinal cord ischemia or, in remaining one case, to ischemic change of the peripheral nerve, In former cases, spinal cord hypoxia might be caused by interrupted blood supply through spinal artery as it was intercepted temporarily but for about three and a half hours during surgical procedures. In the latter case, cramping of the left iliac artery lasted for five and a half hours, which might result in anoxic damage of the peripheral nerve. Hyperbaric oxygenation (HBO) at two atmospheric absolute (ATA) pressure for 75min and 3 ATA for 90min were repeated everyday for them. In all cases, almost complete sensorimotor recovery was obtained after 15 to 30 instances of HBO, which was combined with physical therapy. HBO seemed to have improved early hypoxic and edematous damages of the spinal cord or peripheral nerve. As an unfavorable complication of abdominal aortic surgery, incidence of sensorimotor disturbance of the extremities is infrequent and/or unpredictable, however, once it occurs, no effective therapeutic maneuvers were developed yet. Through these clinical data, HBO should be introduced more actively for such disorders. One of the key issues to enhance the effect of HBO is that, HBO should be introduced as soon as possible once postoperative nuerologic disorders were diagnosed.

[Objective]We performed a questionnaire for the purpose of investigating the present conditions of infection control education in Japanese acupuncture schools and to discuss the problems.
[Methods]We conducted a postal survey by sending out questionnaires to 153acupuncture schools in Japan from December 2008 to March 2009.
[Results]Replies were obtained from 69.9%of the schools (107 out of 153schools). In their responses, 65%of the schools taught hand-washing with soap and alcohol-based hand rub as methods of hand hygiene. Moreover 58%of the schools used only single use needles (SUNs), 40%used both reusable and single use needles, and 2%used only reusable needles. However, single use was observed only at 25%of the schools that introduced SUNs.
Furthermore, we inquired whether the students were taught to use sterilized gloves and finger cots. The results illustrated that a proportion of schools provided the instruction;the proportion of constant instruction was 17%, that of the instructor's option was 35%, that of no requisite was 48%.
[Conclusion]From the above-mentioned results, it became clear that the direction for use of SUNs was not instructed adequately. In addition, this aseptic technique for puncture is not yet standardized in the school's education. It is necessary to realize the measures based on evidence and to employ them in educational programs at acupuncture schools.

A 56-year-old man felt something abnormal in his right upper leg and 2 weeks later, sudden severe pain occurred. He was admitted to our department, on the suspicion of peripheral artery aneurysm. Arteriography showed a right deep femoral artery aneurysm. We successfully treated him with transcatheter embolization. Selective angiography of the deep femoral artery after the embolization disclosed complete occlusion of the aneurysm. We concluded that this minimally invasive treatment by transcatheter embolization for aneurysm of the deep femoral artery may be the first treatment of choice rather than operative resection.

Staged arterial switch operation without homologous blood transfusion was successfully performed in 5 patients weighing 4.1-11.0kg (double outlet right ventricle: 2 cases, transposition of great arteries: 3 cases). The postoperative hemodynamics and respiratory status were uneventful in all patients (initial central venous pressure after ICU admission: 9.0-14.5cmH₂O, mean 12.5cmH₂O, duration of intubation: 3.5-18.0h, mean 7.8h). Autologous blood donation immediately after induction of anesthesia and minimization of bypass circuit were effective methods for open heart surgery without homologous blood transfusion, particularly in staged arterial switch operation requiring prolonged cardiopulmonary bypass.

Although maximal oxygen uptake (VO₂max) or oxygen uptake corresponding to lactate threshold (VO₂@LT) is considered the single best determinant of one's cardio-respiratory endurance or aerobic capacity, the direct measurement of these attributes requires elaborate equipment, trained personnel, special knowledge, and/or a maximal effort on the part of the subject who is tested. In addition, the measurement is time consuming. The current investigation was designed to examine the validity of aerobic capacity estimated from submaximal cycling exercise and field performance tests in the elderly. The subjects tested were 18 sedentary men and women aged 63 to 75 years (69.7±3.4) . Indirect VO₂max tests were selected from those proposed by Astrand and Ryhming, Siconolfi et al., and Margaria et al. (step test), and YMCA. The VO₂max values estimated by these methods, with the exception of the Siconolfi method, were found to have large errors when compared to the errors obtained in previous studies for younger subjects. There were no significant correlations between step test scores and VO₂max and VO₂@LT in the elderly. Correlations of 12-min distance walk with VO₂max (r=.711) and VO₂@LT (r=.714) were significant. Our findings suggest that 12min distance walk be a better aerobic capacity test than other indirect VO₂max tests including Astrand and Ryhming test.

During the period of 25 years from January 1978 through December 2002, a total of 808 colorectal cancer cases were operated on in Shirakawa Kosei General Hospital. The number of sugical resection cases came to 713 (ratio : 88.25%). Curative resection was performed on 593 cases (ratio : 73.4%). The total number of cases was broken down into 446 cases of cancer of the colon and 369 cases of cancer of the rectum (7 multiple cancer cases included). By sex, male cases numbered 329 and female cases 379. Clinically or histologically, many cases were diagnosed as stage IIIa or stage II cancer. The 5-year-survival rate for the resection cases was calculated at 67.2% and that for the cure resection cases, at 79.5%.

Westernization of lifestyles among Japanese, in particular among young generations, is a matter of concern for future increase in coronary heart disease. We surveyed a total of 349 male university students to examine changes in lifestyles and coronary risk factors in campus life. We compared dietary habits and serum fatty acid compositions as well as other coronary risk characteristics between freshmen (n=171) and fourth-year (senior) students (n=178). Serum fatty acid compositions and dietary intakes of selected foods as well as serum lipids, blood pressures and physical characteristics were examined at the 1996 and 1997 annual health examinations. Compared to freshmen, senior students had a lower frequency of fish, vegetable, milk and egg intake, and a higher frequency of oil and fat intake. The proportions of serum saturated and monounsaturated fatty acids were significantly higher among senior students than among freshmen, whereas the proportion of serum polyunsaturated fatty acids was significantly lower among senior students than among freshmen. Senior students also had higher systolic and diastolic blood pressures, percent body fat, smoking rate and alcohol usage than freshmen. Mean body weight and mean body mass index were not different between the two groups. Senior students generally showed Westernized dietary habits and higher coronary risk profiles than freshmen as indicated by the change of serum fatty acid compositions. Modification of these dietary habits and lifestyles may be important for the prevention of future CHD among Japanese young adults.
