Emerging ethical issues have prompted Western countries to focus more attention on public health ethics in medical education. To assess the current and future states of public health ethics education in Japan, we analyzed the opinions of public health educators in Japanese medical institutions and explored potential topics for public health ethics curriculums. 1) We mailed self-administered questionnaires to 201 hygiene and public health departments to inquire about their current curriculums and the state of public health ethics education at their institutions. 2) Of the 101 responding institutions, 60.4% were spending 8% of teaching hours on lectures related to ethical issues in public health. 3) Most institutions agreed with a proposal to require the completion of a public health ethics course in medical education programs. 4) Among the major topics chosen to be included in the potential course were ethical issues surrounding public health policy and medical research.

A 22-year-old man with dilated cardiomyopathy (DCM), who was a practicing Jehovah's Witness, was transferred to our hospital for surgical treatment of medically uncontrollable mitral regurgitation (MR). Our original mitral complex reconstruction procedure and permanent pacemaker implantation for biventricular pacing were successfully performed without transfusion of blood products. Blood conservation strategy included: 1) preoperative treatment with erythropoietin, 2) utilization of a shortened extracorporeal circuit and assisted venous drainage system, 3) the use of ultrafiltration to save the residual autoblood in the extracorporeal circuit. The preoperative hemoglobin level was 17.1g/dl and the postoperative lowest level was 9.5g/dl. MR decreased from grade III to none, and NYHA functional class improved from class II to class I postoperatively. He was moved to a cardiology ward on the 13th postoperative day without complications. Transfusion-free surgery for DCM should be performed before DCM advances and requires left ventriculoplasty at risk for major blood loss. A careful follow-up is needed to examine the long-term results of the operative procedure during his expected long survival.

At the Fujita Health University School of Medicine, about 30% of medical students are admitted on the basis of recommendations.To evaluate the performance of these students after admission, a placement test was given to all new students just after the entrance ceremony to examine basic academic abilities.The scores were compared with the number of absences from lectures and with examination results for the first and second years.
1) The 398 students admitted from 2002 through 2005 were classified into three populations: 126 recommended students, 137 students who scored in the top half on the entrance examination, and 135 students who scored in the bottom half.
2) Scores on the placement test were highest for the top-half students, intermediate for the bottom-half students, and lowest for the recommended students.Scores on examinations in the first and second years were highest for the top-half students, intermediate for the recommended students, and lowest for the bottom-half students.
3) The average number of absences from lectures in the first and second years tended to be lower for recommended students than for the top-half or bottom-half students.
4) The examination scores in the second year were correlated with scores in the first year, and the average number of absences in the second year correlated with those in the first year.
5) These results indicate that the motivation of students in each classification to study in the 1st year is, in addition to their basic academic abilities obtained in high school, an important factor affecting their performance in the second year and beyond.

The aim of this studv was to clarify the effects of water immersion on the cardiovascular recovery process following submaximal steady state exercise on land. Seven male subjects (23 yrs old) underwent experiments under four separate conditions on separate days (15 minutes of cycling exercise at 50% and 80% maximal oxygen consumption followed by 16 minutes of recovery in a sitting position in water and out of water) . Concerning conditions in water, mean water temperature was 29.4 degrees, and the immersion level was set at xiphoid. Mean room temperature in out of water conditions, and during all conditions of exercise, was 24.4 degrees. Oxygen consumption (VO₂), heart rate (HR) and blood pressure (systolic: SBP, diastolic: DBP) were measured under each condi tion. Mean blood pressure was calculated from SBP and DBP (MBP=1/3× ( SBP-DBP) +DBP) . Stroke volume (SV) was measured by Doppler echocardiography, and then cardiac output (CO=SV×HR), total peripheral resistance (TPR=NIBP/CO) and arteriaVmixed venous oxygen difference (a-v O₂diff=VO₂/CO) were calculated. In comparison with the same exercise intensity condition, there were no significant differences between recovery processes of VO₂, HR, SBP, DBP and MBP in and out of water. SV and CO were significantly higher (p<0.05) during the recovery process in water than out of water (SV: at 50 and 80% maximal oxygen consumption conditions, CO: at 80% condition) . The TPR and a-v O₂diff were significantly lower (p<0.05) during the recovery process in water than out of water at 80% oxygen consumption condition. These results indicate that water immersion facilitates circulating blood volume during the recovery process without increasing blood pressure, especially during recovery after high intensity exercise. Therefore, we suggest that increased left ventricular preload with immersion would be an important factor in cardiovascular regulation not only at rest but also during recovery after exercise.

Over 40 years, Post-maketing surveillance (PMS) studies have been conducted as a legal obligation in Japan. Though the contribution of these studies to the better use of the drug has been acknowledged, there are criticisms that these PMS studies have been stereotyped and need to be improved. The ICH-E2E guideline entitled as "Pharmcovigilance Planning", agreed in the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) has been implemented in the concerned countries. The legislation of the guideline in Japan in 2005 seems to have urged drug companies and regulatory agency to review the current PMS practices in contrast with the today's highest scientific standard. We investigated the theoretical and practical aspects of pharmacoepidemiology required when the drug company evaluates safety specification prior to developing the pharmacovigilance plan and designs a PMS study along the lines stipulated in the ICH-E2E guideline. To meet this end, we evaluated the profiles of the drug, summarized "Important identified risks", "Important potential risks" and "Important missing information" to be identified and examined the pharmacovigilance plan suggested by the regulatory agency and that proposed and implemented by the drug company. We examined those aspects for 6 new products selected from 168 drugs newly approved during the period between January 2004 and October 2006. In 5 of 6 cases, we judged that the use of a comparator group would have been appropriate to asses the association between the drug and adverse events of interest. In addition, in one half (3) of 6 cases, it would have been preferable to use the database for the patient registration and/or other types of databases. The issues of relevant legislation and the infrastructure and funding for the investigations needed to develop a desirable study design and conduct a good pharmacoepidemiology study are however beyond a single company's capacity and should be set as a national strategy. The issues of post-marketing safety in the nation is becoming more and more important as the data in the countries outside Japan are being used more often for the processes of marketing authorization application of a new drug and its approval. It is urgent to secure the practice of pharmacoepidemiology to achieve the effective post-approval pharmacovigilance studies.

In the present study, surveys regarding the philosophy of learning were administered just after the entrance ceremony to all students entering the Fujita Health University School of Medicine in 2005 and then, once more, to the same students during the last term of the fourth year, so that the data could be subsequently analyzed. The 87 fourth-year students who completed the surveys were divided into 3 groups(top, middle, and bottom thirds)on the basis of their examination scores in the previous years.
1) Results of the fourth-year survey suggested that students in the middle or bottom third did not develop a "learning-centered campus lifestyle" during their 4 years of medical studies, although the first-year survey indicated that most students in all 3 thirds had desired such a lifestyle.
2) The image of a physician had changed somewhat for students in middle or bottom third but not for students in the top third.
3) Attendance rates in all years of medical study were lower for students in the bottom third than for students in the middle or top third. Moreover, the motivation to study and attend lectures showed a downward trend over time for students in the bottom third.

We report a case of drug-induced cystitis caused by the administration of two different Kampo medicines containing Scutellariae radix. The patient was prescribed bofutsushosan for weight gain at the age of 55. She visited her primary care physician approximately one month later for micturition pain and other symptoms, and was prescribed antibacterial agents based on a diagnosis of bacterial cystitis. The patient’s symptoms persisted even after she was treated for one month ; therefore, she was referred to the urology department of a general hospital. All medicines including Kampo medicines were discontinued ; her subjective symptoms and urinary findings improved within 2 weeks. Her symptoms of cystitis flared up after a few days of re-administration of bofutsushosan. Four months later, she developed cystitis-like symptoms again after using nyoshinsan for menopausal symptoms. Based on the aforementioned clinical observations, she was diagnosed with drug-induced cystitis due to bofutsushosan and nyoshinsan administration. The components of these two Kampo medicines and past history of Kampo medicine use were reviewed and Scutellariae radix was considered to be the causative agent. Drug-induced cystitis caused by herbal medicines generally takes a long time to develop, and symptoms resolve within a relatively short period following discontinuation of the causative agent. Several reports in the literature implicate Scutellariae radix as the etiological agent in such cases. We believe that it is necessary to pay close attention to the risk of cystitis in patients receiving long-term Kampo therapy.

1)We reproduced a problem–based learning (PBL) tutorial at our school and developed our own PBL tutorial, which we call "Fujita–style PBL." This is a clinical problem-solving type of PBL, in which both a monitoring room and small–group learning rooms are used.
2)To maintain the present number of PBL lessons despite the limited number of tutors, one tutor supervises several groups simultaneously. Coordinators observe the progress of PBL from a monitoring room and support the tutors.
3)Students learn the given scenario and identify their learning issues. After they study the learning issues by themselves, the students return to tutorials to explain their learning issues. Thereafter, each group's findings are presented to the groups supervised by one tutor.

1）To learn the techniques required immediately after the start of clinical practice, new residents were introduced to the skills laboratory during their orientation period.
2）We attempted to establish the Yanegawara style, which is an overlapping teaching style in which the second–year residents plan the entire training schedule and simultaneously teach the first–year residents while being supported in their teaching by more senior physicians.
3）Training with the new system resulted in greater rapport among all residents as well as a greater feeling of security among first–year residents.
