A compulsory postgraduate clinical training system, which includes psychiatry as a requirement, will be started in 2004. However, many problems have been pointed out and discussed. In this report we offer 2 suggestions for making clinical training more useful. First, new residents should study not only psychiatric knowledge but also the attitudes of psychiatrists toward patients. Second, we psychiatrists should determine the practical requirements for the training of new residents. In such suggestions are implemented, Japanese psychiatry may change for the better.

A 61-year-old man fell into out-of hospital cardiopulmonary arrest due to rupture of an abdominal aortic aneurysm, and was resuscitated onsite. On arrival at the emergency room, a fusiform type abdominal aortic aneurysm and massive hematoma in the retro-peritoneal space were detected by ultrasonography. Quickly, an aortic occlusion balloon catheter was placed at the proximal site of abdominal aorta through the left brachial artery, and then graft replacement of the aneurysm was carried out. The inferior mesenteric artery was occluded, and was not reconstructed. Five hours after the operation, left hemi-colectomy was carried out for ischemic necrosis of the descending to sigmoid colon. Although he was complicated by multiple organ failure; renal failure, liver dysfunction, severe infection, and brain infarction, he survived without a fatal disability. A rare case with ruptured abdominal aortic aneurysm who fell into cardiopulmonary arrest outside the hospital but survived after bowel necrosis and multiple organ failure is reported.

An 84-year-old man with a thoracic aortic aneurysm underwent total arch replacement with selective antegrade cerebral perfusion. Immediately after the operation, respiratory distress and hypotension developed and Chest X-ray films and computed tomography showed bilateral lung edema. Echocardiography showed a small, underfilled left ventricle, but with preserved systolic function. We suspected transfusion-related acute lung injury (TRALI), and started sivelestat and steroid pulse therapy. His respiratory condition gradually improved, and he was discharged on postoperative day 78. The diagnosis of TRALI was confirmed by positive test results of an HLA class I antibody in the transfused fresh frozen plasma and T- and B-cells of the patient. TRALI should be considered as a cause of acute lung injury after surgery with blood transfusion.

To date a uniform set of standards for the kinesiology and measurement of the degree of flexibility of the human body are not available in Japan. In the methods of measurement of the suppleness of the human body, various distances and angles have been used separately as frames of reference. In the selection of angles for lateral observation on the human body, some investigators have set the standard point of reference at the major trochanter, while others have taken the anterior superior iliac spine as their standard point of reference.
In the present study, the lateral angle of the human body was measured using the anterior superior iliac spine and the major trochanter as the standard points. The values from the measurement of these two points were comparatively studied around the rotation of the pelvis. In 4 male and 4 female university students without joint abnormalities, measurement was carried out in 5 postures (1) normal (2) lordosis (3) flat back (4) flexion of the trunk (5) hyperextension of the trunk.
As the standard points for angle analysis, 4 points, the acromion, anterior superior iliac spine, the major trochanter, and the lateral malleolus were selected. As the angle to express each posture, the anterior angle of the acromion-anterior superior iliac spine-lateral malleolus and anterior angle of the acromion-major trochanter-lateral malleolus were measured.
For the observation of pelvic inclination, the internal angle of the anterior superior iliac spine-major trochanter and the lateral malleolus was measured. In order to analyze this, the range of fluctuation of the postural angle against pelvic inclination around the major trochanter and anterior superior iliac spine was calculated.
As a results, a small variance in the fluctuation of the values of measurement in each test subject would express a change of posture due to pelvic rotation. In each case, the use of the major trochanter gave a small unbiased variance.
In our experience, palpation of the major trochanter or anterior superior iliac spine especially in females revealed less resistance by the former. Consequently, based on these results, the use of the tip of the major trochanter appears to be more reasonable than the anterior superior iliac spine as a reference point for the observation of the human body from the lateral aspect.
It is proposed that the standard point should be placed on the center of the major movable joint to express the posture and other movement, in addition to the anterior superior iliac spine.

Echocardiography was performed in two gruops of patients with impaired renal function excluding those with diabetic renal failure. Group A was comprised of 19 patients who had recieved hemodialysis from 1 year to 5 years, and Group B, of 32 patients who had been undergoing hemodialysis for more than 10 years. Significant reductions in left ventricular diastolic dimensions and cardiac output were found in Group B. In these two groups, there were no statistically significant differences in left ventricular wall thickness and left ventricular ejection fraction. Left ventricular diastolic function was assessd by the ratio of the peak atrial velosity (A) to early diastolic velosity (E). 15 patients (83%) in Group A and 19 patients (76%) in Group B had left ventricular diastolic dysfunction. A high incidence of left ventricular diastolic dysfunction was revealed. Moreover, dilated and hypertrophic cardiomyopathy like patterns were observed in both groups. In Group B, significantly increased left ventricular wall thickness in patients with hypertension and reduced left ventricular systolic function in patients with dialysis hypotension were found.

Among 62 patients who underwent hybrid arch TEVAR, which is a combination of supra-aortic bypass and TEVAR to treat arch aneurysm, 5 patients encountered postoperative cerebral infarction. In 2 patients, whose thoracic aorta were extremely shaggy, cerebral infarction were multiple and fatal. Other 3 patients, whose aorta were not shaggy, developed visual disturbance after TEVAR and minor cerebral infarction were detected in the area of vertebral artery. To prevent cerebral infarction after hybrid arch TEVAR, the blood flow from the left subclavian to vertebral artery is considered to be significant.

Objective. We investigated whether the aging-related decrease in gap junction expression affects myocardial response against ischemia-reperfusion injury of the rabbit myocardium. Methods. Isolated aged (≥135 weeks) or mature (15-20 weeks) rabbit hearts were perfused with Krebs-Henseleit solution via a Langendorff apparatus, and were divided into five groups as follows: 7 mature hearts served as mature controls (Group A), 7 mature hearts underwent ischemic preconditioning (IPC) consisting of two cycles of global ischemia for 5min followed by reperfusion for 5min (Group B), 7 aged hearts served as aged control (Group C), 7 aged hearts underwent IPC (Group D) and 7 mature hearts received 1mM of gap junction uncoupler heptanol for 5min (Group E). Then, all hearts were subjected to 1h of left anterior descending coronary artery occlusion followed by 1h of reperfusion. Left ventricular pressure, ischemic zone monophasic action potential and coronary flow were measured throughout the experiment and the infarct size (IS) was determined at the end of the experiment. Gap junction expression was investigated by the electron microscopy. Results. The IS of Group A was 39.1±3.8 (%) and that of Group B was 26.9±3.8 (%)* (*p<0.05 vs. Group A). The IS of Group C was 19.3± 1.6(%)*. That of Group D was 43.6±5.8 (%)# (#p<0.05 vs. Group C). IS of Group E was 24.3±1.6 (%)*. Electron microscopic findings demonstrated that gap junction expression in aged hearts was less prominent than in mature ones. Conclusion. These data suggested that aged myocardium might be more tolerant of ischemic insult than that of mature heart, and that the mechanism might be related to the aging-related change of gap junction expression.

A 59-year-old man presented with severe abdominal pain. CT scan showed a type A aortic dissection and pericardial effusion. As cardiac tamponade was present, emergency total arch replacement was performed. Because of his symptom, we added an exploratory laparotomy, which revealed intestinal necrosis. Therefore, necrotic intestine 4.5m in length was resected. After intensive care, he began oral feeding on the 25th day and was discharged on the 76th day postoperatively.

IABP is in wide clinical use as an effective adjunctive means for the management of seriously impaired cardiac function. Unfortunately, however, it is an undeniable fact that this specialized circulatory support technic has so far been used in severe heart disease cases in a desultory way, with no established criteria being available for indication of elective IABP for prophylactic purposes. Under such circumstances, it was felt worthwhile to analyze data on preoperative left ventricular function from a series of open heart surgery cases (25 treated with and 94 without IABP) encountered in our hospital since 1983 (when procedure for myocardial protection was virtually standardized) in an effort to formulate acceptable criteria for indication of elective IABP. Hemodynamic parameters studied were LVESVI, LVEF and LVEDP. The results led us to conclude that scheduled IABP can be regarded as indicated for use in each of the following valvular heart diseases if at least one of the respective criteria specified below is fulfilled: MR: LVESVI≥120ml/m2, LVEF≤0.4, LVEDP≥21mmHg; AR: LVESVI≥135ml/m2, LVEF≤0.4, LVEDP≥18mmHg; MS: LVESVI≥70ml/m2, LVEF≤0.35, LVEDP≥23mmHg.

OBJECTIVE: Recent investigations have revealed DNA mismatch repair (MMR) gene mutations are closely related with carcinogenesis of endometrial cancer; however the impact of MMR protein expression on prognosis is not determined. Correlations between MMR-related protein expression and clinicopathological factors of endometrial cancers are analyzed in the present study. METHODS: A total of 191 endometrial cancer tissues treated between 1990 and 2007 in our hospital were enrolled. Immunoreactions for MSH2, MLH1, MSH6, and PMS2 on tissue microarray specimens and clinicopathological features were analyzed retrospectively. RESULTS: Seventy-six cases (40%) had at least one immunohistochemical alteration in MMR proteins (MMR-deficient group). There were statistically significant differences of histology, International Federation of Gynecology and Obstetrics (FIGO) stage, and histological grade between MMR-deficient group and the other cases (MMR-retained group). Response rate of first-line chemotherapy in evaluable cases was slightly higher in MMR-deficient cases (67% vs. 44%, p=0.34). MMR-deficient cases had significantly better progression-free and overall survival (OS) compared with MMR-retained cases. Multivariate analysis revealed MMR status was an independent prognostic factor for OS in endometrial cancers. CONCLUSION: MMR-related proteins expression was identified as an independent prognostic factor for OS, suggesting that MMR was a key biomarker for further investigations of endometrial cancers.
