To examine the status of pharmaceutical industry support for junior residency education in Japan, we performed a questionnaire survey of 445 residency program directors (response rate, 76%).
1) Fifty-one percent of respondents thought that industry support was necessary for education, and 28% did not believe that industry support negatively affects residents’ prescribing behaviors.
2) Twelve percent said their institutions had a curriculum for physician-industry relationships. Ten percent prohibit residents from meeting with pharmaceutical representatives, and 30% ban gifts from industry.
3) Fifty-one percent reported that they had pharmaceutical industry-sponsored in-hospital educational events for residents, and 73% reported that they had industry-sponsored in-hospital educational events which residents were allowed to attend.
4) Program directors’ belief that industry support was necessary for education predicted that programs would receive such support.

A 70-year-old woman was admitted with precordial pain. Two-dimensional echocardiography revealed a right atrial tumor. CT scan also showed a high density tumor in the right atrium. Right atriography demonstrated a mobile tumor with a stalk arising from the vicinity of the Eustachian valve. On open heart surgery the stalk of the tumor seen to be attached to the Eustachian valve. The tumor was very hard because of massive calcification. Removal of the tumor was accomplished in the standard fashion, excising the Eustachian valve together with surrounding endocardium to prevent recurrence. The weight of the tumor was 20g and the size was 6×3×2cm. Histologic examination of the tumor revealed myxoma. Thirty five cases of right atrial myxoma have been reported in Japan. There was only one previous report which reported a case originating from an Eustachian valve.

BACKGROUND:
More than 140 million people drink arsenic-contaminated groundwater. It is unknown how much arsenic exposure is necessary to cause neurological impairment. Here, we evaluate the relationship between neurological impairments and the arsenic concentration in drinking water (ACDW).
PARTICIPANTS AND METHODS:
A cross-sectional study design was employed. We performed medical examinations of 1867 residents in seven villages in the Thabaung township in Myanmar. Medical examinations consisted of interviews regarding subjective neurological symptoms and objective neurological examinations of sensory disturbances. For subjective neurological symptoms, we ascertained the presence or absence of defects in smell, vision, taste, and hearing; the feeling of weakness; and chronic numbness or pain. For objective sensory disturbances, we examined defects in pain sensation, vibration sensation, and two-point discrimination. We analyzed the relationship between the subjective symptoms, objective sensory disturbances, and ACDW.
RESULTS:
Residents with ACDW ≥ 10 parts per billion (ppb) had experienced a "feeling of weakness" and "chronic numbness or pain" significantly more often than those with ACDW < 10 ppb. Residents with ACDW ≥ 50 ppb had three types of sensory disturbances significantly more often than those with ACDW < 50 ppb. In children, there was no significant association between symptoms or signs and ACDW.
CONCLUSION
Subjective symptoms, probably due to peripheral neuropathy, occurred at very low ACDW (around 10 ppb). Objective peripheral nerve disturbances of both small and large fibers occurred at low ACDW (> 50 ppb). These data suggest a threshold for the occurrence of peripheral neuropathy due to arsenic exposure, and indicate that the arsenic concentration in drinking water should be less than 10 ppb to ensure human health.

Medical students at Kurume University begin practical training in clinical skills in their fourth year. At that time, students use the skills laboratory to improve their clinical skills. Medical education resources in the skills laboratory include simulators for emergency resuscitation and heart diseases, wireless stethoscopes, and videotapes. All students use the skills laboratory for 2 months, and its usefulness was evaluated with questionnaires after practical training. More than 50 % of students approved of their practice in the skills laboratory. However, some students were unsatisfied because they were unable to make effective use of the simulators. In the future, an improved skills laboratory will be necessary to improve practical training in the clinical skills for medical students.

We analyzed the scores of objective structured clinical examinations (OSCEs) and written examinations administered to fourth-year medical students after practical training in clinical skills and to fifth-year medical students after clinical training and scores of graduation examinations taken by sixth-year medical students. Correlations were analyzed among the scores of 96 students who had taken all 3 examinations during a 3-year period. Mean scores on examinations in the fourth, fifth, and sixth years were compared between sixth-year students who did or did not graduate and between graduating students who did or did not pass the national examination for medical practitioners in Japan. Significant correlations in the scores were found between 1) OSCEs and written examinations for fourth-year students versus those for the fifth-year students; 2) OSCE and written examinations for fourth-year students versus graduation examination scores for the sixth-year students; and 3) OSCE and written examinations for fifth-year students versus graduation examination scores for sixth-year students. In addition, the mean scores in the fourth and fifth years were significantly higher for sixth-year students who graduated and passed the national examination than for students who did not graduate or who graduated but failed the national examination. These results suggest that the practical training in clinical skills given to fourth-year students and the clinical training given to fifth-year students strongly affect the overall evaluation of the ability of sixth-year students and success on the national examination.

In this revision, we have attempted to align the Model Core Curriculum for Medical Education competency, "problem-solving ability based on specialized knowledge," with the "Standards of National Examination for Medical Practitioners." The major diseases and syndromes in "Essential Fundamentals" correspond to the basic diseases in Table 1 of the Core Curriculum, symptoms, physical and laboratory examinations, and treatment in "General Medicine" correspond to the items in Table 2 of the Core Curriculum, and the diseases in "Medical Theory" correspond to the diseases in PS-02 of the Core Curriculum. The validity of the diseases in the Core Curriculum was verified using the evaluation results of the examination level classification of the "Research for Revision of National Examination Criteria." Approximately 690 diseases were conclusively selected. This revision mentions the number of diseases in the Core Curriculum for the first time. Hopefully, this will lead to a deeper examination of diseases that should be studied in medical schools in the future.
