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.

A 31-year-old woman was admitted to our hospital with a sudden onset of chest pain and dyspnea. Echocardiography, chest CT, and chest MRI revealed a huge mass in the right atrium. She underwent pericardial drainage to alleviate cardiac tamponade. Emergency surgery was performed because of superior vena cava syndrome and the risk of tricuspid valve obstruction by the mass. The tumor was resected en bloc, including the right atrial wall and a large segment of the proximal superior vena cava. The right atrium was then reconstructed with a Xenomedica patch and the superior vena cava was reconstructed using an expanded polytetrafluoroethylene (ePTFE) vascular graft. The pathological diagnosis was haemangiosarcoma. Cardiac angiosarcoma is a rare tumor, and its prognosis is very poor. The patient could survive for about 5 months after surgical resection.

The purpose of this study was to clarify physical characteristics related to low back pain (LBP) in collegiate track and field athletes. We particularly focused on the nature of the track and field. The subjects were 21 male collegiate track and field athletes including only sprinters, hurdlers, long jumpers and triple jumpers. The examined parameters were physical characteristics, isokinetic flexor and extensor strength in the knee and trunk regions. The evaluation of LBP was estimated by a questionnaire test and orthopedic surgeons' diagnosis. According to these evaluations, we divided all track and field athletes into two groups ; LBP group (n＝11, 52.4%) and no LBP group (n＝10, 47.6%). As a result, a take-off leg of knee flexor/extensor strength ratio in the LBP group was significantly lower than that in the no LBP group (P＜0.05). The LBP group showed a significant difference between a take-off leg and a lead leg in knee flexor strength compared with the no LBP group (P＜0.05). The LBP group has been short engaged in the track and field than the no LBP group (P＜0.05). In the trunk flexor and extensor strength, there was no significant difference between the LBP and the no LBP group in this study. These results suggest that the imbalanced knee muscle strength may be one of some factors related to chronic low back pain in collegiate track and field athletes.

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.

BACKGROUND: Focusing on the respiratory function for health effect indices, we conducted a cross-sectional study on workers who did and did not handle toner to compare the longitudinal changes. METHODS: Among 116 individuals who worked for a Japanese business equipment manufacturer and participated in the study, the analysis included 69 male workers who we were able to follow up for 4 years. We categorized the 40 workers engaged in toner-handling work as the exposed group and the 29 workers not engaged in these tasks as the referent group, and compared their respiratory function test results: peak expiratory flow rate (PEFR), vital capacity (VC), predicted vital capacity (%VC), forced expiratory volume in 1 second (FEV1), and forced expiratory volume in 1 second as a percent of forced vital capacity (FEV1%). RESULTS: The cross-sectional study of the respiratory function test results at the baseline and at the 5th year showed no statistically significant differences in PEFR, VC, %VC, FEV1, and FEV1% between the exposed and referent workers. Also, respiratory function time-course for 4 years was calculated and compared between the groups. No statistically significant differences were shown. CONCLUSION: Our study does not suggest any toner exposure effects on respiratory function. However, the number of subjects was small in our study; studies of larger populations will be desired in the future.
