A preparticipation examination for athletes should be performed to prevent severe athletic injury by examining physical characteristics related to various injuries. The general joint laxity test has been included among the check-up items considering as relating factor of joint injury. Authors investigated the relationship between the score of general joint laxity for freshmen examination and the incidence of major joint injury, during the succeeding 5 athletic seasons, in eighty-seven collegiate American football players.
Significant higher scores were observed in athletes affected by shoulder injury, and slightly higher scores in those affected by knee joint injury. But, the scores were similar between athletes with and without elbow or ankle injury.
The degree of laxity was associated with shoulder and knee joint injury in a comparison of incidence of these injuries among tight, medium and lax groups.
Authors concluded that general joint laxity is related to the incidence of shoulder and knee joint injury.

The purpose of this study is to investigate the degenerative change of the cervical spine in American football (AF) players. The subjects were 27 collegiate AF players who had an annual radiological examination of the cervical spine. X-ray films of the lateral view were read by digital scanner and the anterior and posterior height of each spine (C 3-C 6) was measured. The subjects were divided into two groups based on experience of AF in high school (inexperienced and experienced) or the position played (lines and backs) .
Although the anterior height did not change from the first grade to fourth grade, the posterior height of C 4, C 5 and C6 significantly increased (P <0.05) . The experienced group showed a faster increase in the rate of posterior height than the inexperienced group. Also, the backs group showed a faster increase in the rate of posterior height than the lines group. The increased posterior height, which sometimes includes bony spur, results in kyphotic change of cervical alignment and impingement of the cervical nerve root. The faster growth rate in experienced or backs groups suggests that higher mechanical stress to the cervical spine and younger start of AF caused degeneration.

To estimate the incidence of liver injury related to Kampo medicine containing Scutellaria baicalensis, all medical records in our clinic were retrospectively examined. Among 2,430 patients who took Kampo medicine containing Scutellaria baicalensis, liver blood tests were performed in 1,547 cases (63.7%). The possibility of liver injury related to Kampo medicine containing Scutellaria baicalensis could not be denied in 19 cases (1.2%) among the 1,547 cases. The clinical features of liver injury in 19 cases were not different from those in previous reports. In agreement with the previous literature, this study also suggests that the incidence of liver injury related to Kampo medicine containing Scutellaria baicalensis is about 1%.

Purpose: Head and neck cancer patients receiving chemoradiation therapy often suffer from severe mucositis. Chemoradiation therapy-induced mucositis is usually accompanied by severe and intractable pain that impairs quality of life. To establish an effective method for treatment of mucositis pain, we retrospectively investigated the relationships of radiation dose with severity of mucositis and opioid consumption. We also conducted a survey on satisfaction of pain treatment. Methods: Study 1: Fourteen patients who underwent chemoradiation therapy of 70 Gy for head and neck cancer from 2005 to 2009 participated in the study. The relationship of severity of mucositis with opioid use was studied. Study 2: Seven patients who had mucositis of over grade 3 and had completed radiation therapy participated in the study. We carried out a questionnaire survey about satisfaction of each pain treatment. Results: Study 1: Increase of radiation dose significantly worsened the severity of mucositis. Opioid consumption for treating pain was significantly greater in the pharynx cancer group than in the oral cancer group. Study 2: Oral care treatment was preferred to systemic administration of analgesics including opioids. Conclusions: In the oral cancer group, oral care treatment was thought to be useful for pain treatment. Oral cancer patients needed less opioids than did pharynx cancer patients.

A new educational program for the medical doctor was introduced at Tokyo Women's Medical College in 1990 with a 4-year tutorial education model as its core. To develop the program for educational training more efficiently, current facilities were reviewed on a large scale, and various types of equipment and supplementary materials were made available. We are now investigating utilization and problems of the current program. Supplies and materials of tutorial rooms and mirror rooms have been used effectively. The library has become increasingly useful as a place for independent study and research. However, audiovisual materials have not yet been made fully available. We suggest that further improvements to the system and fostering an environment of open access to information are necessary to increase the accessibility of the support system for tutorial education.

Tutors must understand their role in advance so that tutorial education can be conducted smoothly and effectively. These abilities and attitudes require training. At our school, tutors serve as faculty for basic courses and clinical courses. We assessed their training conditions and future tasks. Of the 1, 077 faculty members who received tutor training between 1988 and 1997, 935 are current faculty members who have completed in-service training (basic course, 115; clinical course, 820). Before 1989, training was on campus, but since 1990 it has been conducted at Shirakawa Seminar House with a 2-day program. The number of working tutors per year is 192, with a basic course to clinical course ratio of 3: 7. About half of the faculty members in the basic course have had four or more experiences as tutors, whereas most clinical course faculty members have had only one experience. Thus, many tutors have had no experience. In a questionnaire survey after undergoing the training program, most participants felt that they were able to understand the theory of tutorial education and the actual role of the tutor and that they were able to concentrate on off-campus training that was removed from their everyday work. To provide added impetus to tutorial education, we suggest that in the future, in addition to the understanding and mutual cooperation of those involved, it will be necessary to provide an advanced program to train tutors who have appropriate abilities and attitudes.

Tokyo Women's Medical University introduced tutorial education in 1990 for 1st-through 4th-year students. To examine the effectiveness of this system in a basic-medicine course, questionnaires were given to all 2nd-year students. Many students felt that they had become accustomed to performing self-learning tasks through collecting information themselves and discussing their findings in a group; in particular, they found that tutorial education markedly improved their communication skills. A few students thought that this method helped them develop the ability of logical/critical thinking and analytic skills from multiple viewpoints. These findings suggest that an assessment system should be established by which students themselves could recognize the extent to which they have developed their abilities, which was the aim of tutorial education.

Personal interviews and group discussions were conducted with all 2nd-year students to examine how they feel about tutorial education used as the core of the basic-medicine course and how they recognize the importance of developing their abilities, which was the aim of this course. Many students showed slight anxiety about the results of their learning with tutorials, felt inadequate in their self-learning ability, and hoped the guidance by instructors would be improved. These findings suggest that students' anxiety will decreased and their willingness to learn will increase if their developed abilities are evaluated appropriately and if they receive adequate feedback. These findings also suggest that a retraining program for experienced instructors is needed to improve their guidance skills and to reinforce the importance of their role.

A thirty-eight-year old woman with facial pain was diagnosed with trigeminal neuralgia, and treated with conventional carbamazepine therapy. Although the pain was alleviated to a certain degree, she visited our clinic to receive Kampo therapy. Judging from her facial injury in an accident thirty years ago, jidabokuippo was administered in addition to carbamazepine. The trigeminal neuralgia was then relieved, and Takagi's tender point in her abdomen was also reduced or disappeared. She could finally stop carbamazepine therapy. This case suggests that neuralgia patients with previous injury and Takagi's tender point can be treated with jidabokuippo.
