Retrospective cohort study. This study aimed to investigate relationships between clinical outcomes and radiographic parameters in patients with pseudoarthrosis after posterior lumbar interbody fusion (PLIF). In some patients with pseudoarthrosis after PLIF, clinical symptoms improve following surgery, although pseudoarthrosis can often be one of the complications. However, there are no previous reports describing differences between patients with pseudoarthrosis after PLIF who have obtained better clinical outcomes and those who have not. Twenty-seven patients who were diagnosed with pseudoarthrosis after single-level PLIF with cortical bone trajectory screw fixation (CBT-PLIF) were enrolled in this study. They were divided into two groups based on mean improvement of 22 points on the Oswestry Disability Index (ODI) at the 2-year follow-up. Group G consisted of 15 patients who showed improvement on the ODI of ≥22 points, and group P consisted of the residual 12 patients. Radiographic parameters, percentage of slip, lumbar lordosis (LL), segmental lordosis, segmental range of motion, screw loosening, and subsidence were compared between the two groups. There were no significant differences between the two groups on radiographic parameters except for postoperative changes in LL. Although surgery-induced changes in LL showed no significant difference between the two groups, changes in LL from before surgery to 2-year follow-up and during postoperative 2-year follow-up were significantly better in group G (mean change of LL: +3.5° and +5.1°, respectively) compared to group P (mean change of LL: −4.6° and −0.5°, respectively) ( Patients with greater improvement in ODI gained LL over the 2-year follow-up, whereas patients with less improvement in ODI lost LL during the 2-year follow-up. These results indicate that there is a significant correlation between clinical outcomes and LL even in patients with pseudoarthrosis after single-level CBT-PLIF.

Kampo medicines have been used for treatment by an increasing number of doctors in recent years, and are becoming more frequently prescribed in combination with Western drugs. In the present study, we conducted a questionnaire of outpatients at the Kampo Clinic of Keio University Hospital in order to determine their perceptions and compliance regarding Kampo medicines.Ninety eight percent of patients used Kampo medicines in granular form, and approximately 30% of these patients reported difficulty in taking medicine due to reasons such as “bad taste”. Sixty percent of patients used Kampo medicines three times daily. Patients most often forgot to take afternoon doses, and so desired doses once daily. Furthermore, the same number of patients preferred Kampo medicines in tablet form as those who preferred Kampo medicines in granular form.The present findings clarified patients' perceptions toward Kampo medicines. Doctors and pharmacists must provide suitable treatment for patients by recognizing their perceptions of Kampo medicines.

Background : Since 2002, Keio University Hospital's Kampo Clinic has promoted itself actively through the media, public presentations, faculty outreach and an internet home page. However, the relative value of these promotions is unknown. Additionally, the range and prevalence of presenting concerns, and the ages and the gender ratio of the patients served at Keio is unknown.Objective and Methods : To better understand and better serve the patients, the medical charts of every new patient who presented to Keio University Hospital's Kampo Clinic from November 2004 to November 2005 (n=791) were retrospectively analyzed for 1) referral source, 2) age, 3) gender, and, 4) disease category.Results : The internet webpage was by far the best source of new patient referrals. The out-of-hospital referral rate to the clinic was remarkably low. Women exceeded men by a 3 : 1 ratio. Most women were in their thirties but male patients were fairly evenly distributed across the age spectrum. Patients under 16 and over 70 were gender-balanced. The vast majority of patients presented with general medicine/pediatric, dermatological or gynecological problems.Conclusion : A patient-oriented internet home page provides a good source of new patient referrals. Given the low rate of referrals from outside hospitals and physicians, additional outreach directed at internal medicine, dermatology or obstetrics/gynecology physicians appears warranted.

Generally, sport players of boxing or football who contact roughly with other players use mouth guard during match or game to prevent the breaking of jow boneor bursting of soft oral cavity. Moreover, mouth-guard are used for the purpose to lighter the load to root of teeth and to improve the skill and power of sport's player.
The purpose of this study was to examine the charactaristic of unfitted by H shape-mouth guard compared to U shape mouth guard.
The following results were obtained.
1. The H shape-mouth guard of this study could reduce the impact to 1/7 level.
2. A relative decrease in ventilation level was shown when H shape mouth guard fitted.
3. With reference to respiratory function, reduction of the amount of oxygen up-take was not observed at heart rate lower than 170 beats/min, and in this case a player feells subjective symptom of stiffing.

We have developed a mouth guard which has revolutionized the shape and material of the conventional mouth piece. The H shape mouth guard has the unique shape like that of an H. Even with the new shape of the mouth piece it does not hinder the performance of the wearer. The following are the fundamental data collected by our group. In this study we examined its influences on leg power, the carry (the distance a golf ball is hit) and the motion of the club head during a tee off.
The results are as follows:
1) By wearing or setting the mouth guard, the variation of leg power, measured with a Sybex II, showed an increase at selected angular verocity. The rate of increase averaged aproximately 15%.
2) The amount of work in anaerodush, an intensive, but short exercise, increased significantly by 1.25 seconds.
3) As for golf, all four of the test subjects joint performance increased their carries by 5.2 to 11.6 yards, using a 1st wood.
4) Also the fluctuation of the head of the club decreased from 7.3 cm to 3.6 cm on average.
Our group have found that the new H shaped mouth guard can absorb shock as well as not hinder the performance of the individual who is wearing it. Thus, the H shape mouth guard can be worn during sports to enhance the participant's performance.

Discussions on the postgraduate medical school and the speciality training course after graduation had been conducted 2 times in 1994 among the members of the working group on postgraduate medical school and speciality training in Japanese Society for Medical Education. Results of the discussion are reported in this paper as a proposal for the improvement of the present state of education and training in the postgraduate medical schools in our country. In this report, several important proposals which need further discussions such as the shortening the clinical course in postgraduate medical school to 3 years from present 4 years and necessity of establishing the obligatory course for training the basic technology for life science research are presented. It is mandatory to have full time teaching staff as well as exclusive space for postgraduate course in each school to improve the of education of postgraduate medical schools.

Medical Education 1990;21(2):84-87
A comparison of simple true-false questions (STFQ) and multiple choice questions (MCQ) plus multiple true-false questions (MTFQ), in the same contents was done at the graduation examination of our department (on 1987. 12. 7.). The mean score of STFQ was 83.7 mark and its standerd deviation was 4.6 mark, and in MCQ plus MTFQ the value was 77.1, 9.0, respectively. At the same student, the mark of STFQ and MCQ plus MTFQ was correlated. We concluded that the handling of the question with high percent of correct answer was induction of the individual total item check method. Then, evaluation got more validity.
