A questionnaire survey of newly enrolled medical students on the sensitivity to human death and dying was conducted at Yamaguchi University in June 1997 and June 1998. The survey was performed during lectures of an elective liberal arts course in medical ethics for first-year students. Responses were received from 415 students, including 63 medical students. Answers from new medical students were compared with those from new students of other faculties. Our results show that our medical school entrance examination does not generally select students with a high motivation for bioethics. We should consider further improvement in the curriculum of the introduction to medicine (igakugairon in Japanese).

We introduced active educational methods in medical ethics education and evaluated their effect on medical students. Three methods were used: 1) small-group discussion to clarify the clinical ethical issues, 2) self-study to analyze examples of doctors' explanations to patients, and 3) self-study with videotapes to recognize informed consent. We asked students to write a report on each subject of the three studies. Before grading their reports, we determined a standard answer for each subject and marked their reports according to an absolute standard. We found the mean value and standard error of the students' scores in study 1 were significantly higher than those in study 2 or 3. These results suggest that small-group discussion is an effective educational method and useful in the analysis of clinical ethical issues.

Purpose:We evaluated that the current state from which a palliative care unit receives emergency admission of cancer patients at home. Methods:We retrospectively investigated the medical records of 393 cancer patients who hospitalized in our unit between January 2013 and December 2014. The patients were shared with a group of two, schedule admission (schedule group) and emergency admission (emergency group), and it was compared with a result on discharge and with a hospitalization period. We investigated admission process, the date and time of admission, and reason for admission in emergency group. Results:The number of patients was 224 of schedule group and 169 of emergency group. The mortality rates were 81% in schedule group and 78% in emergency group (not significant). An emergency group for an average of 24.3 days was shorter for 9 days than schedule groups in a hospitalization period of dead leaving patients (p<0.05). In emergency group, admission process included 128 completed-interviews with the hospitalization, 11 incompleted-interviews before admission and 30 first visits, and 129 patients (76%) admitted within the weekday daytime. Many patients had a complaint of severe pain, appetite loss and oral absorption difficulty, and so much. Conclusions:An emergency group admitted the various processes and the much symptom. There were a lot of cases of early hospital death, but also admitted return at home, and our unit played the role of emergency admission.

Recently, as the practical training for clinical skills are extensively introduced in the curriculum of medical schools, the objective structured clinical examinations (OSCEs) is taken to assess the clinical skills of trainees. However, there have been very few papers mentioned about correlation between scores on a written examination of the clinical sciences and those on OSCE in Japan. In this study, to compare these of two kinds of examinations in year five medical students of Yamaguchi University, their scores of the stations of OSCE and those of the written examinations of clinical sciences which seemed to correlate stations of skill's examinations were studied statistically. As a result, there were no statistical significances in each scores between skill's evaluations and written tests. This results that these two examinations estimated the different abilities of students on the taxonomy of medical education. Moreover, OSCE is reconfirmed to be identical as an evaluative method of clinical skills. Now, new medical educational systems should be introducted for the training of skills and attitude for students.

Students' interviewing skills are now commonly evaluated with standardized patient-based assessment methods. Four pairs of instructors at Nihon University School of Medicine used objective structured clinical examinations to evaluate the medical interviewing skills of 122 fifth-year medical students. The results were then analyzed to improve the accuracy of rating with objective structured clinical examinations. Interrater variability was significant among the two pairs of instructors. Variability was greatest when instructors evaluated a student's performance but was minimal when they judged whether a student had carried out a task. The number of standardized patients was 8, with the average score of each standardized patient ranging from 52.5 to 73.3 (full score, 100). These results suggest that the rating process for each item should be further refined and that the standard for evaluation should be clarified.

We reported a 74-year-old female complicated by ostial obstruction of the left main trunk after aortic valve replacement for severe aortic stenosis. At surgery, the length from the orifice of the left main trunk to the aortic annulus was 3 mm. After a 19 mm Carpentier-Edwards PERIMOUNT MAGNA was implanted in supra-annular position, the orifice of left main trunk was concealed by a sewing cuff of the bioprosthesis. Before aortic declamping, saphenous vein graft was bypassed to the left anterior descending artery. The postoperative course was uneventful. Computed tomography demonstrated the ostial obstruction of the left main trunk by the bioprosthesis.

A 71-year-old man who had undergone repair of a ruptured abdominal aortic aneurysm with a tube graft 3 months ago was transferred from another hospital with an Aortoenteric Fistula (AEF) for surgical treatment. Computed tomographic (CT) angiography revealed pseudoaneurysm formation at the proximal anastomotic site. Waiting for the elective operation, he developed massive hematemesis with shock. Endovascular stent-graft repair was emergently performed because of high risk for conventional open surgery. Gastrointestinal bleeding was successfully controlled. The psuedoaneurysm disappeared, which was confirmed by postoperative CT angiography. At 1-year follow-up, he has shown no clinical and radiographic evidence of recurrent infection or bleeding. For the case with shock, Endovascular repair could be a bridge to open surgery because it is fast and minimally invasive. Endovascular repair of AEF is technically feasible and may be the definitive treatment in selected patients without signs of infection and gastrointestinal bleeding.

Objective: The efficacy of botulinum toxin type A (BoNT-A) injection on spasticity has usually been measured using the range of motion (ROM) of joints and Modified Ashworth Scale (MAS); however, they only evaluate muscle tone at rest. We objectively analyzed the gait of three patients with hemiplegia using three-dimensional motion analysis and ground reaction force (GRF) systems to evaluate muscle tone during gait.Materials and Methods: We measured passive ankle dorsiflexion ROM with knee extension and the MAS score for clinical evaluation, and gait speed, stride length, single-leg support phase during the gait cycle, joint angle, joint moment, and GRFs for kinematic evaluation before and one month after BoNT-A injection.Results: All patients showed an increase in ankle dorsiflexion ROM, improvement in MAS score, and increase in stride length. Case 1 showed an increase in gait speed, prolongation of the single-leg support phase, increase in hip extension angle and moment, and improvement in the vertical and anterior-posterior components of the GRFs. Case 2 showed an increase in gait speed, improvement in double knee action, increase in ankle plantar flexion moment, and improvement in propulsion in the progressive component of the GRFs. Case 3 exhibited a laterally directed force in the GRFs.Conclusion: We evaluated the effects of BoNT-A injections in three patients with hemiplegia using three-dimensional motion analysis and GRFs. The results of the gait analysis clarified the improvements and problems in hemiplegic gait and enabled objective explanations for patients.

Although the pelvic autonomic plexus may be considered a mixture of sympathetic and parasympathetic nerves, little information on its composite fibers is available. Using 10 donated elderly cadavers, we investigated in detail the topohistology of nerve fibers in the posterior part of the periprostatic region in males and the infero-anterior part of the paracolpium in females. Neuronal nitric oxide synthase (nNOS) and vasoactive intestinal polypeptide (VIP) were used as parasympathetic nerve markers, and tyrosine hydroxylase (TH) was used as a marker of sympathetic nerves. In the region examined, nNOS-positive nerves (containing nNOS-positive fibers) were consistently predominant numerically. All fibers positive for these markers appeared to be thin, unmyelinated fibers. Accordingly, the pelvic plexus branches were classified into 5 types: triple-positive mixed nerves (nNOS+, VIP+, TH+, thick myelinated fibers + or -); double-positive mixed nerves (nNOS+, VIP-, TH+, thick myelinated fibers + or -); nerves in arterial walls (nNOS-, VIP+, TH+, thick myelinated fibers-); non-parasympathetic nerves (nNOS-, VIP-, TH+, thick myelinated fibers + or -); (although rare) pure sensory nerve candidates (nNOS-, VIP-, TH-, thick myelinated fibers+). Triple-positive nerves were 5-6 times more numerous in the paracolpium than in the periprostatic region. Usually, the parasympathetic nerve fibers did not occupy a specific site in a nerve, and were intermingled with sympathetic fibers. This morphology might be the result of an "incidentally" adopted nerve fiber route, rather than a target-specific pathway.

The paracolpium or paravaginal tissue is surrounded by the vaginal wall, the pubocervical fascia and the rectovaginal septum (Denonvilliers' fascia). To clarify the configuration of nerves and fasciae in and around the paracolpium, we examined histological sections of 10 elderly cadavers. The paracolpium contained the distal part of the pelvic autonomic nerve plexus and its branches: the cavernous nerve, the nerves to the urethra and the nerves to the internal anal sphincter (NIAS). The NIAS ran postero-inferiorly along the superior fascia of the levator ani muscle to reach the longitudinal muscle layer of the rectum. In two nulliparous and one multiparous women, the pubocervical fascia and the rectovaginal septum were distinct and connected with the superior fascia of the levator at the tendinous arch of the pelvic fasciae. In these three cadavers, the pelvic plexus and its distal branches were distributed almost evenly in the paracolpium and sandwiched by the pubocervical and Denonvilliers' fasciae. By contrast, in five multiparous women, these nerves were divided into the anterosuperior group (bladder detrusor nerves) and the postero-inferior group (NIAS, cavernous and urethral nerves) by the well-developed venous plexus in combination with the fragmented or unclear fasciae. Although the small number of specimens was a major limitation of this study, we hypothesized that, in combination with destruction of the basic fascial architecture due to vaginal delivery and aging, the pelvic plexus is likely to change from a sheet-like configuration to several bundles.
