Background : Perioperative care in congenital heart surgery has evolved in recent years, and it was considered a contributive factor to improve surgical outcome and prognosis. Objective : To extract perioperative clinical protocols that have been applied in our hospital, then assess their usefulness for better clinical outcome. Methods : We retrospectively reviewed our patients' records to analyze representative perioperative protocols that might have contributed to surgical outcome, such as intraoperative transesophageal echocardiography (ITEE), extubation in the operating room on patients of atrial septal defect (ASD), ventricular septal defect (VSD), tetralogy of Fallot (TOF), Glenn procedure and Fontan procedure. We also assessed clinical pathway of ASD and VSD, and each protocol was individually explored to calculate achievement ratio in order to show its adequacy. Results : This study included 482 of on-pump surgery patients and 146 of off-pump surgery patients from June 2007 to June 2014. ITEE was performed in 474 of on-pump surgery patients and 102 of off-pump surgery patients. No case had a residual lesion immediately after operation. Extubation in the operating room was performed in cases without severe pulmonary hypertension (PH). The extubation ratio was 94.7% (ASD repair), 60.0% (VSD repair), 50.0% (TOF repair), 42.5% (Glenn procedure), and 45.2% (Fontan procedure), respectively. Clinical pathways of ASD and VSD included patients without severe PH. Achievement ratio of the clinical pathway was 98.2% in ASD and 94.2% in VSD patients, respectively. Four patients were excluded because of high c-reactive protein (CRP), and one patient because of familial circumstance. Conclusion : ITEE was useful in evaluation of cardiac function, residual issue and residual air at weaning of cardiopulmonary bypass. Reintubation did not occur in any clinical course of extubation in the operating room, but the extubation rate was not high because of safety concerns. Achievement ratio of the clinical pathways of both ASD and VSD was more than 90%, therefore, application of the clinical pathway was considered appropriate.

We investigated sports disorders in 112 (82 men, 30 women) members of Field and Track Club, University of Tsukuba.
Before acupuncture treatment, they entered their painful and fatigued areas in our chart and were tested by Cornel Medical Index.
After six months, we questioned 51 (38 men, 13 women) members treated by acupuncture on effects.
The following results were obtained.
1. The painful areas varied with athletic events, that were muscles and joints they moved frequently.
The painful areas were mostly low backs and thighs in a short distance and hurdle race, hips and legs in a middle and long distance, low backs and legs in a jumping event, elbows and low backs in a throwing event.
2. As a result of Cornel Medical Index, it was proved that many members had more mental than physical symptoms.
3. Most of members treated by acupuncture could still go on with training in spite of pains.
4. The effects of treatment continued for 2-3 days.
5. The effects were rated as follows: better 78.4%, no change 14%, worse 6%.

A 66-year-old man with an unknown medical history developed chest pain and a diagnosis of acute myocardial infarction (AMI) was given by his physician. Percutaneous coronary intervention was performed in the left anterior descending artery. Echocardiography revealed ventricular septal perforation (VSP) ; therefore, the patient was transferred to our hospital. After admission, his platelet count dropped rapidly during heparin administration, and left ventricular thrombosis and deep vein thrombosis were noted, raising a suspicion of heparin-induced thrombocytopenia (HIT). To establish cardiopulmonary bypass, argatroban alone was insufficient to prolong the Powered by Editorial Manager^® and ProduXion Manager^® from the Aries Systems Corporation activated clotting time (ACT) ; thus, nafamostat mesilate was also used for coronary artery bypass grafting and surgical repair of VSP. It took many hours to normalize the ACT, requiring re-exploration for excessive bleeding. On the 37th postoperative day, the patient was transferred to another hospital. We performed cardiac surgical procedures using argatroban in a patient who developed HIT during the course of VSP following AMI ; however, we had difficulty in controlling the ACT. Since, to the best of our knowledge, there are no previous studies reporting surgical case of VSP complicated by HIT, we present this case with a review of the relevant literature.

To evaluate the efficacy of the retroperitoneal approach (RP) when compared with the transperitoneal approach (TP) in elective aortoiliac reconstruction, 41 cases were reviewed. From February 1987 through October 1991, 16 patients underwent aortoiliac reconstruction through the TP approach and 25 patients underwent operation through the RP approach for abdominal aortic aneurysms (AAA). The TP approach was associated with larger intraoperative blood loss (648.6±416.5ml) when compared with the RP approach (357.7±208.9ml) (p<0.01). The TP approach was associated with greater intraoperative blood transfusion (2093.8±1179.0ml) when compared with the RP approach (1010.4±905.3ml) (p<0.01). Both groups had similar operative times. Postoperative initiation of oral water intake was prolonged in the TP group (50.2±27.4hr) when compared with the RP group (22.3±8.9hr) (p<0.01). Postoperative initiation of walking training was prolonged in the TP group (88.7±37.1hr) when compared with the RP group (60.1±23.2) (p<0.01). This experience demonstrates that the RP approach is a preferable alternative to the TP approach in elective aortoiliac reconstruction.

The vascular endothelial function is impaired in the very early stage of atherosclerosis in diabetic patients. The goal of this study was to identify the mechanism underlying the improvement in vascular endothelial function by sitagliptin in type 2 diabetes mellitus patients. This study was an open-labeled prospective observational single arm trial. Forty patients were treated with 50 mg of sitagliptin once daily for 12-weeks. The flow-mediated dilation (FMD) and plasma adiponectin were measured at baseline and 12 weeks after initiating treatment. The %FMD was significantly increased after treatment (4.13 +/- 1.59 vs 5.12 +/- 1.55, P < 0.001), whereas the nitroglycerin-mediated dilation (NMD) did not change. The plasma adiponectin levels significantly increased (13.0 +/- 11.3 vs 14.3 +/- 12.8, P < 0.001). The changes in the FMD were significantly correlated with those of the plasma adiponectin (r = 0.322, P < 0.05). A multivariate linear regression analysis demonstrated that the improvement in the FMD is associated with the plasma adiponectin (P < 0.05). The treatment of type 2 diabetes mellitus patients with sitagliptin reverses vascular endothelial dysfunction, as evidenced by increase in the FMD, and improvement of the adiponectin levels (UMIN Clinical Trials Registry System as trial ID UMIN000004236).

Methods: We examined the computed tomography scans from the thoracic vertebra to the sacrum used to diagnose DISH in 140 patients (98 men and 42 women; average age, 78.6 years). We compared patients who did (n=52) and did not have (n=88) fractures at the continuous vertebral bodies fused by bone bridges. The relationship between the vertebral fractures and the maximum number of vertebrae that are bony cross-linked with contiguous adjacent vertebrae (max VB) from the thoracic vertebra to the sacrum or from the lumbar vertebra to the sacrum and proximal femur BMD were analyzed using a logistic regression model. Results: We found that after adjusting for the confounding factors, higher max VB, both from the thoracic vertebrae to the sacrum and the lumbar vertebrae to the sacrum, was associated with a higher risk of vertebral fractures. This difference was statistically significant. The risk was higher when only the lumbar vertebrae to the sacrum was considered (thoracic vertebrae to the sacrum: odds ratio, 1.21; p<0.05; lumbar vertebrae to the sacrum: odds ratio, 2.78; p<0.01). Moreover, low proximal femur BMD in DISH patients raises the fracture risk (odds ratio, 0.47; p<0.01). Conclusions Many continuous vertebral bone bridges, especially those that extend to the lumbar spine and low proximal femur BMD, are risk factors for fracture in DISH patients.

A 59-year-old man was admitted to our hospital with severe mitral incompetence. Mitral valve repair, tricuspid annuloplasty and the Maze procedure were performed. After weaning from cardiopulmonary bypass, his systolic blood pressure (SBP) dropped to 40 mmHg. Immediate administration of catecholamines markedly increased SBP but his continuing low blood pressure required additional treatment with vasopressin and hydrocortisone. On postoperative day 12 in the general ward, he suddenly lapsed into an intractable hypoglycemic coma. Endocrine function tests revealed adrenocorticotropic hormone deficiency. Since the time of writing has been doing well with 20 mg of hydrocortisone.

From May 1975 to August 1991, 90 patients (56 males and 34 females) underwent Bentall's operations or its modified technique. In our modified technique the coronary ostium is cut out like a button and anastomosed to the aortic graft and aortic grafts are not wrapped by the aortic wall. Preoperative diagnoses were AAE (25 patients, 28%), Stanford type A dissection (19, 21%), Marfan's syndrome (16, 18%), aortitis syndrome (12, 13%), AR+ascending aortic aneurysm (6, 7%), syphilitic aortitis (5, 6%), AS+ascending aortic aneurysm (3, 3%), Valsalva's sinus aneurysm (2, 2%) and other diseases (2, 2%). The hospital mortality rate was 17% (15/90) for all cases. The hospital mortality for aortic dissection (37% (7/19)) and reoperation cases (75% (3/4)) were very high. There were 10 cases of late death and the 10 year actuarial survival rate was 66.3%. Among 11 cardiovascular events which occured in the late phase, 5 were dissection at other aortic sites in the type A dissection and Marfan syndrome cases, and 3 were pseudoaneurysm formation at the site of coronary or the aortic anastomosis in the aortitis syndrome cases, and a detachment of the composite graft in the Marfan's syndrome cases. The 10-year event-free rate was 92.0% for non-specific AAE, 68.8% for aortitis syndrome, 61.9% for Marfan's syndrome and 47.3% for Stanford type A dissection. Non-specific AAE had excellent long-term results, but Marfan's syndrome and dissection had poor results. The button technique for coronary reconstruction is effective for all cases and its long term results are good, but, even with this technique, coronary pseudo-aneurysm occured in cases of aortitis syndrome.
