To evaluate training methods for basic clinical skills before bedside learning, we used questionnaires to ask students and instructors their opinions about the fixed-instructor system, in which one instructor teaches the entire course, and the rotation system, in which instructors share responsibilities for teaching according to their specialty. Students had positive impressions of training with both systems. Many students felt that communication with in structors was good inthe fixed-instructor system and that the specialized education provided by multiple instructors was good in the rotation system. However, students expressed dissatisfaction about differences in educational content between the systems. Instructors believed an advantage of the fixed-instructor system was that skills learned could be applied to all medical fields, whereas the rotation system made teaching easier because it was specialized. On the basis of this investigation, we conclude that training should establish good communication between instructors and students and should include the required educational contents. We also found that unifying educational contents is difficult, regardless of the training system. Few reports about educational methods used to teach basic clinical skills have been published in Japan, but studies focusing on this issue are becoming increasingly necessary.

1) We investigated the patients'evaluations of the students, our management of the medical training, and the patients' recognition of our outpatient clinic education. We then requested the patients to give their opinions regarding such interviews.
2) The patients'evaluations of the outpatient clinic and the patients'recognition of our outpatient clinic education were relatively good, but some patients complained about the short duration of medical care and also expressed anxiety over the students'medical interview.
3) Many patients expressed the desire to positively participate in medical education because the patients had high expectations of the medical students.In addition, this interview training fulfilled the patients'desire to be listened to and have their concerns acknowledged.

BACKGROUND: In general practice, though patients often stop visiting ambulatory clinics of their own vo-lition despite the need for ongoing medical treatment, there is little reported research on the reasons for nonattendance in Japan. In this study, we investigated whether the patient/doctor relationship influences nonattendance rates in general practice. In addition, we investigated the reasons why patients stopped visiting the hospital.
METHODS: We collected data from 115 patients (58 males, 57 females; age range: 16 to 94 years old, median age: 52 years old) whose initial diagnoses were made in our department from June to July 2000. We classified the patients into five groups based on the level of their complaints concerning the initial consultation (‘A’ representing the highest degree of complaint, ‘E’ representing the lowest) and determined the relationship between the strength of complaints and the non-attendance rate. Furthermore, we investigated the reasons for non-attendance concerning 28 patients who stopped visiting the hospital from April 2000 to November 2001.
RESULTS: The non-attendance rates were 0% (014) for group A, 14.3% (2114) for group B, 5.6% (5189) for group C, 33.3% (216) for group D, and 50% (1/2) for group E. The rate tended to be higher in groups with fewer complaints. The reasons for non-attendance were the following: remission of symptoms (9 patients), request for another hospital or department (6 patients), relief due to consultation at the university hospital (6 patients), and lack of time to come to the particular hospital (5 patients) . In contrast, the most common reason for satisfaction at the time of consultation was ‘enough explanation and listening to complaints well’ in 7 of 11 patients who were satisfied with the consultation.
CONCLUSIONS: The level of patient's complaints at the time of consultation is related to the non-attendance rate. However, sufficient explanation about symptoms and careful listening to complaints are important for establishing a good patient/doctor relationship.

To clarify changes in body temperature during endurance exercise in patients with spinal cord injury (SCI), we measured tympanic temperature (Tty) and skin temperature in the head, arm, chest, thigh, shin and calf in 5 patients with SCI (T6-T 12) and 7 normal controls during 30 minutes arm cranking exercise (20 watts) from 10 minutes before the initiation of exercise until 10 minutes after the termination of exercise in an artificial climate room at a temperature of about 25°C with a relative humidity of about 50%. The Tty in the SCI group was lower than that in the control group from 10 minutes before the initiation of exercise to 10 minutes after the termination of exercise with a significant difference only at the initiation of exercise. The difference in Tty slightly decreased with continuation of exercise. The Tty in the SCI group at rest was 36.05-37.15°C. Four patients in this group showed a decrease of 0.04-0.12°C in the early stage and an increase of 0.66°C±0.19 (mean±SD) at the end of exercise over the value at the initiation of exercise.
The skin temperature was lower in the SCI group than in the control group in all sites excluding the arm. Significant differences were observed in the head in the early stage of exercise and after exercise, in the chest from 10 minutes before the initiation of exercise to 5 minutes after the termination of exercise, in the thigh from 10 minutes before the initiation of exercise to 10 minutes after the termination of exercise, in the shin 10 minutes and 5 minutes before the initiation of exercise, and in the calf from before to 15 minutes after the initiation of exercise. In the SCI group, marked individual differences were observed in the skin temperatures in the thigh, shin, and calf, suggesting specificity of the skin temperature response in and near the paralysis area.
Results in Tty in this study suggested no heat retention in the SCI patients. Therefore, the risk for heat disorders seems to be low during moderate or mild exercise under moderate temperature environment at a temperature of about 25°C with a relative humidity of about 50% even when the skin temperature is low, and thermolysis is not marked.

Coronary artery obstruction, pulmonary stenosis, aortic valve regurgitation, and enlargement of the neo-aortic root are major complications of arterial switch operation (ASO) for transposition of the great arteries (TGA). Supravalvular aortic stenosis following ASO is rarely reported, and technical factors should be considered as causes in such cases. We report a case of supravalvular aortic stenosis following ASO, in which we speculated that the cause of the stenosis was tissue overgrowth caused by the surgical suture. The patient was a 4-month-old girl with TGA (II) who had undergone ASO on the 12th day after birth. Neo-aortic anastomosis was performed with 7-0 polydioxanone absorbable suture (PDS^®, Ethicon, Somerville, NJ, USA). Transthoracic echocardiography performed 1 month after the surgery showed severe stenosis at the aortic anastomosis which worsened progressively. Therefore, the patient was reoperated 4 months after the previous surgery. The concentrically stenosed aortic wall at the anastomotic site was resected and aortic reanastomosis was performed using an interrupted suture pattern with 7-0 polypropylene (Prolene^®, Ethicon). The histological findings showed proliferation of collagenous fibers around the PDS^® suture. Because of the worsening stenosis over time and the histological findings, we speculated that the tissue overgrowth in reaction to the PDS^® suture was the main cause of the stenosis. Absorbable sutures are useful because they do not leave a foreign substance in the body ; however, the possibility of tissue overgrowth leading to anastomotic stenosis cannot be denied. When using absorbable suture, careful observation is mandatory until the material is completely absorbed.

  This research was performed with the family assessment tool at critical and emergency care settings (CNS-FACE) as a standard tool at the ICU of Hospital A. It clarified changes in the awareness and practice of family support by staff in order to obtain clues to how to provide family support in the future.
  Initially, a briefing session was held to acquaint nurses with CNS-FACE. A total of 28 nurses assigned to the ICU were invited to the session. They were informed of the importance of using CNS-FACE to understand the family needs and coping. The staff members were requested to use CNS-FACE to obtain an objective assessment of patients' families selected at random by the nursing research members. Subsequently, questionnaires were distributed to investigate the changes in the nurses' awareness. Those who reported a change in relationship with the families after using CNS-FACE accounted for 100% of the nurses with one to three years' experience, 64% of the urses with four to six years' experience, and 50 % of the nurses with seven or more years' experience. An understanding of the 46 items in CNS-FACE was thought to lead to more positive intervention awareness. It was believed that this would result in a reduction in stress for nurses providing family nursing and to bring about a change in their awareness of family nursing, irrespective of their number of years of nursing experience. CNS-FACE gave the nurses with one to six years' experience with an objective understanding of needs and coping and changed their awareness of family nursing. A change of awareness was achieved by 50% of the nurses with seven or more years' experience. Over 60 % of the staff members recognized CNS-FACE to br effective for family nursing.

The purpose of this study was to investigate the effect of constant endurance cycling exercise below Ventilatory Threshold (VT), under different pedal rate/torque regulations (PTR), on muscle oxygenation, as well as cardio-respiratory function and energy metabolism. Eight healthy male adults participated in the study for three tests. The first test was to examine the maximum oxygen uptake (VO₂max) using a ramp loading measurement of 60 rpm, 20 watt/min ; and an individual 80%VT load was obtained. The second and third tests (random) were to measure heart rate (HR), blood pressure (MAP), expired gas and NIRS data before, during and after 30 min 80%VT constant cycling exercise with low pedal rate/high torque (LPHT : 32 rpm, 23.3±6.0Nm) or high pedal rate/low torque (HPLT : 79rpm, 9.4±2.4Nm). As a result, HPLT showed higher values in HR (p<0.001), MAP (p<0.001), VO₂ (p<0.001), VCO₂ (p<0.001) and RER (p<0.05), than LPHT ; but LPHT showed a higher fat consumption rate than HPLT (p<0.05). Significant PTR effect were recognized for the parameters of the tissue hemoglobin index (THI) (p<0.001) and oxygenation hemoglobin (ΔO₂Hb) (p<0.01) ; and both indicated higher values for HPLT than LPHT ; but LPHT showed insignificantly (p=0.066) higher de-oxygenation hemoglobin (ΔHHb) than HPLT. Moreover, the significant time effects of THI and ΔO₂Hb were also recognized. In conclusion, this study indicated that during constant cycling exercise below VT, HPLT might result in greater muscle blood volume, higher muscle oxygenation concentration and higher HR and VO₂ compared with LPHT. These results suggest that, HPLT might be effective in alleviating the working load on lower limbs, as well as promoting muscle oxygenation, cardiorespiratory function (systemic oxygen supply) and energy metabolism. Therefore, HPLT constant cycling exercise below VT could be used in a rehabilitation program as a beneficial exercise for elderly people with decreasing muscle strength in their lower limbs.

The decrease of balance capacity is considered as a high risk factor of fall accident, so it is important for the middle-aged and elderly people to keep balance capacity on a high level. In this study, we investigated the effects of aqua exercise on dynamic and static balance function. Thirty-two middle-aged women (56.6±8.1 years) participated a 60-min aqua exercise program three times per week for eight weeks. After exercise intervention, body weight, body mass index, grip strength, side step, shuttle stamina walking test were significantly improved (p<0.05-0.001). Functional reach (p<0.001) and total length of centroid shake with eye close condition (p<0.05) was significantly improved, but with eye open condition was not changed. However, when we evaluate the total length of centroid shake by T-score, static balance performance with eye open and close condition was significantly (p<0.05) improved in the below average groups. In addition, measurement value of functional reach was also improved in these groups. These results indicate that aqua exercise benefits not only physical muscle strength and endurance capacity, but also balance function in middle-aged women. Particularly aqua exercise is more effective for the subjects with lower static balance function before intervention.

We investigated the relationship between body weight reduction and intensity of daily physical activities assessed with 3-dimensional accelerometer during a 3-month exercise program. Twenty-six middle-aged women (58.1±7.4 yrs.) participated in this study. Participants underwent a 90-min endurance exercise intervention once a week, and a 3-dimensionsal accelerometer was attached through the program. Body weight (BW), body mass index, fat mass and percent body fat were reduced significantly (p<0.001), while diastolic blood pressure (p<0.01) and shuttle stamina walking test (p<0.05) improved significantly after the exercise intervention. Moreover, a significant negative correlation was observed between the changes in BW and total activity time (TAT) per day of more than 3METs (TAT≥3METs)(r=−0.580, p<0.01) and TAT≥4METs (r=−0.627, p<0.001). To the contrary, the daily steps and the TAT≥2METs were not related to the changes in BW. After adjusting daily steps, TAT≥3METs (β=−0.630, p<0.01) and TAT≥4METs (β=−0.659, p<0.01) were still significantly related to the changes in BW. These results indicate that weight reduction has a much closer relationship with exercise intensity than daily steps. It is important to keep both quantity and intensity of exercise in the unsupervised exercise program aimed at weight reduction.

A 69-year-old woman had syncope and aphasia. Magnetic resonance imaging showed multiple cerebral infarctions in both hemispheres. Cardiogenic embolisms were suspected, but no arrhythmic causes were shown. Transesophageal echocardiography revealed a highly calcified mitral annulus (MAC) with a rough intraluminal surface and mild mitral regurgitation, but no thrombus or tumor in the left heart system. However, recurrent multiple cerebral embolisms occurred in spite of strict anticoagulation therapy. We speculated that spontaneous rupture of the MAC was the cause of the scattered cerebral embolisms, and we therefore planned to remove the MAC as safely as possible and to endothelialize the deficit of MAC with autologous pericardium. Operative findings revealed that the MAC in P2-P3 had ruptured longitudinally and the ostium of the left atrium was connected to the ostium of the left ventricle as an inter-atrioventricular tunnel beneath the posterior mitral annulus with a fragile calcified wall. The finding suggested that calcified particles that had peeled away from the MAC by normal heart beating resulted in the cerebral infarctions. Therefore, she underwent resection of the MAC and mitral valve replacement with reinforcement of the decalcified posterior mitral annulus between the posterior left ventricular wall and the left atrial wall using autologous pericardium, which enabled both appropriate insertion of a mechanical prosthetic valve and endothelial continuity covering the surface of the residual MAC. No systemic embolism has occurred for two and a half years after surgery. This is the first case report of cerebral embolism caused by a spontaneously ruptured MAC.
