During past 7 years, 43 patients less than 2 years of age underwent closure of the ventricular septal defect. Durations of postoperative use of a respirator were 3 days or less in 30 patients (short-period group) and over 3 days in remaining 13 patients (long-period group). There was no operative death. Pre-, intra- and postoperative factors affecting prolonged respiratory care were analyzed between two groups. Results were as follows: There were statistically significant differences between short- and long-period groups on age (9.7 versus 6.5 months), body weight (6.3 versus 5.2kg) at surgery, necessity of preoperative respiratory care on respirator (0/30 versus 4/13), duration of cardiopulmonary bypass (108 versus 132min.), aortic clamp time (56 versus 70min.) and respiratory index at the first postoperative day (1.1 versus 1.7). These results revealed the necessity of far earlier surgical intervention in symptomatic patients before respiratory distress develops. Furthermore, shorter cardiopulmonary bypass and aortic clamp times should always be in mind for attaining smooth postoperative course.

A 38-year-old man underwent surgery for impending rupture of an inflammatory celiac artery aneurysm with a maximum diameter of about 50 mm. First, an extra-anatomical bypass was performed from the iliac arteries to the celiac artery, superior mesenteric artery and bilateral renal artery using ringed ePTFE grafts. Second, the celiac artery aneurysm at the distal site was directly closed and then a stent graft was placed in the abdominal aorta to cover the orifice of the celiac artery. An endovascular stent graft treatment combined with extra-anatomical bypass is useful for the treatment of inflammatory aneurysm to avoid the various surgical complications in Behçet syndrome.

A 46-year-old man was given a diagnosis of hypertension about 20 years previously. At age 41, aortitis syndrome was diagnosed, with descending thoracic aortic aneurysm and the coarctation of abdominal aorta by CT scan. He then underwent surgery to replace the descending thoracic aortic aneurysm and right axillo-bifemoral bypass. Recently, a thoraco-abdominal aortic aneurysm was pointed out at the distal site of the graft and, he was referred to our institute. We occluded the distal end of the aneurysm using an endoluminal occlusion stent graft. Today, in most cases of aortopathy associated with aortitis syndrome, surgical replacement of the aneurysms and extra-anatomical bypass is performed. An endovascular stent graft treatment combined with extra-anatomical bypass could be useful for various aortic disorders.

We report a rare case of a large thrombus in the ascending aorta with acute arterial occlusive disease. A 61-year-old man was transferred to our hospital with sudden pain and cyanosis. Contrast-enhanced computed tomography detected left ulnar arterial occlusion and a large mass in the ascending aorta, so we performed surgery to remove the large thrombus under cardiopulmonary bypass. Histologically, the mass was a fibrin thrombus. In addition, thickened endothelial lining and slight atheromatous degeneration was detected in the resected aortic wall. The patient was discharged from the hospital on postoperative day 22.

Objective : To examine the association between the combination therapy of calcium antagonists with angiotensin converting enzyme (ACE) inhibitors and underlying diseases for hypertensive patients.
Design : Cross-sectional survey of the drug utilization.
Methods : This survey included 603 hypertensive patients who had visited Toyama Medical and Pharmaceutical University Hospital, Toyama, Japan more than twice from January to June in 1996 and received the prescriptions of calcium antagonists and/or ACE inhibitors. Main outcome measure was the combined medication of calcium antagonists with ACE inhibitors. Underlying diseases under consideration were diabetes mellitus (DM), hyperlipidemia (LIPID), ischemic heart disease (IHD), chronic heart failure (CHF), and ischemic stroke (STROKE).
Results : Out of 603 hypertensive patients, 57.5% received only calcium antagonists, 23.7% received only ACE inhibitors, and 18.7% received both of them. Patients with either IHD or CHF tended to receive the combination therapy as compared to DM or LIPID. Although men tended to receive the combination therapy, a gender effect might be a confounder for the association. Logistic regression showed a 33% increase (P=0.265) in frequency of the combination therapy in patients with IHD after adjusting for age and gender.
Conclusion : Some underlying diseases were associated with more frequent prescriptions of the combination therapy for hypertensive patients, especially with ischemic heart diseases. This result should be regarded as an exploratory stage although the pattern of antihypertensive drug use could be reasonably explained from the pharmacological sense.

To confirm the safety and efficacy of a low-calorie mayonnaise supplemented with phytosterol esters (PEM) at a daily consumption dose of 884 mg given for 12 weeks with the goal of lowering serum low-density lipoprotein (LDL) cholesterol levels, we conducted a double-blind comparative study in healthy adults with marginally high serum levels of LDL cholesterol and total cholesterol using a mayonnaise without phytosterol esters supplementation (CM) as the control food. Serum LDL cholesterol levels decreased significantly in the PEM group as compared with the CM group during the 12-week intervention period (136.3 ± 16.4 vs. 145.0 ± 19.3 mg/dL at Week 8 (P < 0.05) and 135.0 ± 17.4 mg/dL vs. 144.9 ± 17.5 mg/dL at Week 12; P < 0.05). No observable adverse effects were observed due to the ingestion of PEM in this study. The safety of PEM was again confirmed by an additional clinical study in which healthy adult subjects ingested a 3-fold greater amount of PEM (2,652 mg of phytosterol esters as a daily dose) for 4 weeks. Thus, we concluded that PEM is effective in lowing serum levels of LDL cholesterol and is safe and well tolerated without any clinical problems.

Two hemodialysis patients underwent coronary artery bypass grafting. Emergency coronary artery bypass grafting was performed in one patient with unstable angina and acute left ventricular failure. The other patient underwent a combined operation of coronary artery bypass grafting and replacement of abdominal aortic aneurysm. In both patients, hemofiltration was used during cardiopulmonary bypass. In the early postoperative periods, peritoneal dialysis and extracorporeal ultrafiltration method (ECUM) were used in Case 1, while Case 2 was treated by hemofiltration and ECUM. Postoperative coronary angiography showed that all grafts of both patients were patent, and both patients weve discharged from hospital without angina.

A 49-year-old man presented in emergency center with complaints of severe lumbago and severe pain of the right lower limb. Symptoms were suggestive of hernia nuclei pulposi and he was referred to orthopedic department of our hospital. His pain was not relieved by analgesics and the right lower leg was cyanotic with a swollen, hard, and tender calf. On palpation a pulsating mass was revealed in the mid-abdomen. He was transferred to the cardiovascular floor. CT and IA-DSA revealed an abdominal aortic aneurysm and no occlusion of the major arteries of the right lower leg. The serum glutamic oxaloacetic, lactic dehydrogenase levels all increased especially the creatinine phosphokinase increased to 46, 460IU/l, and the urine myoglobin level was 4, 200ng/ml. Myonephropathic metabolic syndrome (MNMS) was suspected. Urine volume was maintained with fluid infusion and diuretics. The blood urea nitrogen and potassium levels remained within normal limits throughout the course. The immediate recognition of MNMS and treatment of the condition were successful in preventing serious complications. But all the toes of the right foot became necrotic and they were amputated. Two months after admission, replacement of the abdominal aortic aneurysm was performed successfully. The patient was discharged in good condition one month after the operation.

The purpose of this study was to evaluate the effectiveness of water exercise, including functional mobility in water, performed either once or twice a week in elderly who require nursing care. Twenty-one subjects were assigned to two groups. Ten subjects trained once a week for 6 months. Eleven subjects trained twice a week for 6 months. Water exercise consisted of warming up on land and walking,ADL exercise,resistance training, stretching and relaxation in water. Functional mobility was evaluated by FIM during pre-exercise,after 3 months and 6 months. There were significant improvements in functional mobility after 6 months compared to pre-exercise in both groups. Functional mobility in the group who trained once a week did not improve at 3 months compared to pre-exercise. Although the group who trained twice a week showed a dramatic improvement in functional mobility after 3 months compared to pre-exercise, and no change after 3 months compared to after 6 months. These results indicate that water exercise once or twice a week for 6 months, including functional mobility in elderly who require nursing care, can improve functional mobility, especially, exercise twice a week could improve it within 3 months.

A 45-year-old woman was admitted for acute left hemiplegia and left hypogastric pain. Central CT showed a right parietal lobe infarction. Abdominal CT demonstrated ovarian tumor and infarction of the liver, spleen and kidney. Chest radiography showed moderate cardiomegaly. Transthoracic echocardiography demonstrated vegetation in the aortic valves and severe aortic regurgitation. Aortic valve replacement and bi-adnexectomy were performed urgently. Intraoperative examination revealed normal aortic valves except for small amounts of vegetation on leaflet surfaces. Pathological diagnosis of vegetation was fibrin without inflammatory cells or bacteria. The postoperative course was uneventful, and the patient was discharged 13 days after surgery without a permanent neurological deficit. Trousseau syndrome caused by ovarian cancer and nonbacterial thrombotic endocarditis is rare, and it is important to be aware of this syndrome in the case of a young cerebral infarction patient with malignant disease.
