The purpose of this study was to investigate the benefits of sports participation in the prevention of pressure sores. A questionnaire was mailed to 668 men and woman with spinal cord injury. The questionnaire was designed to clarify the effects of physical activity and lifestyle on the development of pressure sores. Usable questionnaires were received from 466 persons, representing a response rate of 70%. Thirty-eight percent were quadriplegic and 62% paraplegic, with incomplete injuries accounting for 26% of the combined group. About half of the 466 subjects reported the development of pressure sores in their wheelchair life. Only 34% of the active subjects, participated in sports regularly, reported the development of pressure sores in their wheelchair life. On the other hand, 49% of the inactive subjects who did not participate in wheelchair sports reported the development of pressure sores. When the development of pressure sores before sports participation was compared with that after commencement of sports participation, there was no significant difference in the development of pressure sores between these periods. It was concluded that although quadriplegics and paraplegics without pressure sores had a greater tendency to participate in sports activity, there were no clear positive benefits of sports involvement on the prevention of pressure sores.

A 57-year-old male had single bypass graft to the right coronary artery with a saphenous vein graft 20 years previously. He noticed recurrent anginal pain since 1991 and thoracic aortic aneurysm was also pointed out in 1993. Coronary angiography showed that the saphenous vein graft was occlusion, accompanied with the distal portion of the occluded anterior descending coronary artery perfused by collateral flow from the circumflexus branch. The left ventricular function was moderately impaired (EF=38%). Re-do of coronary artery bypass grafting was done to the AV branch of the right coronary artery with the right gastroepiploic artery and the primary sequential grafting to anterior descending coronary artery and diagonal branch with left internal thoracic artery. One month after CABG, graft replacement of descending thoracic aorta was done because of thoracic aortic aneurysm. The postoperative course was uneventful except for the complication of chylothorax after the second operation. Postoperative angiography showed good patency of the left internal thoracic artery and right gastroepiploic artery and no abnormality of the graft anastomosis.

A 61-year-old male had received aortic valve replacement due to AR in 1987 and the operative findings showed the enlargement of the ascending aorta and maximum diameters of 4cm in the ascending aorta. He had been doing well until 1992 when he sufferred cerebral infarction and aortic root dilatation reached a maximum diameter of 7.5cm demonstrated by CT. Cabrol's operation using the previously replaced aortic valve was carried out because the prosthetic valvular function was normal and the type of coronary arteries was balanced. Postoperative angiography showed good patency at anastomosis of bilateral coronary arterial orifices and he had a satisfactory postoperative course. The dilatation of the ascending aorta over 4cm accompanied with AR may need not only AVR but also aortic root replacement.

A 64-year-old woman with a diagnosis of calcified aortic valvular stenosis and unstable angina, had calcification of the aortic valve reaching the aortic annulus, and the ascending aorta had some calcifications in its lateral and posterior walls. There was a 70mmHg pressure gradient in the aortic valve and coronary angiogram showed 90% stenosis of right coronary artery #1 and total occlusion of left circumflex artery #13 perfused with collateral flow from right coronary artery. The translocation of the aortic valve was carried out. The postoperative course was uneventful and postoperative angiograms showed good patency of the double saphenous vein grafts and no abnormality of the composite graft anastomosis. Translocation of the aortic valve is effective in patients with stenotic aortic annulus caused by calcified aortic valve, although it is mainly indicated in infective endocarditis.

This study was performed to clarify the analgesic effect of ketamine injected into the first intercoccygeal (Co1-Co2) epidural space in standing cattle. Five adult cows were randomly received 3 treatments at least 1 week interval: 5, 10 and 20 mL of 5% ketamine. Sedation, analgesia, ataxia and other effects on cardiopulmonary and rumen functions were assessed before ketamine administration and until 120 min. The analgesia without sedation was shown at tail and perineum about 5 min after all three treatments. The duration of analgesia was significantly increased according to the volume of ketamine (p < 0.01). There was a similar tendency of ataxia with individual variation. There were minimal effects on cardiopulmonary and rumen functions. The present study showed that caudal epidural ketamine administration induced analgesia without sedation in cows, and the duration of analgesia was dose dependent with ataxia. However, the duration of analgesia after 5 and 10 mL ketamine administration is short for common surgical procedures and pain relief of perineum. Further studies are needed to prolong the duration of analgesia without side effects.

Horseshoe kidney is an unusual abnormality occurring in 0.25% of the population. In surgery for AAA with horseshoe kidney, reconstruction of aberrant renal and preservation of renal isthmus is important. We report 3 cases of AAA with horseshoe kidney treated successfully without division of the isthmus.

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.

The Jichi Medical School has trained doctors for work in community health care for over 20 years.Students learn medical communication skills by role-play. In this role-play, doctors and patients areplayed by students. Discussions are also held by students. The teaching staff give additional explanations, suggestions and demonstrations. By themselves, students learn about 1) general practice, 2) theprocess of consultation, 3) medical communication and 4) patients' emotions. We plan to develop othereducational resources such as trained simulated patients.

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.
