A pseudoaneurysm of the ascending aorta is a complication found in aortic valve surgery. A 66-year-old man who had a previous history of aortic valve replacement due to infectious endocarditis was admitted to our hospital suffering from chest pain. Follow-up chest X-ray and transthoracic echocardiogram had revealed no findings of pseudoaneurysm during the intervening period. At admission, computed tomographic scan and transesophageal echocardiogram each showed a Type A acute aortic dissection and a pseudoaneurysm of the ascending aorta. Under cardiopulmonary bypass and deep hypothermic circulatory arrest, an ascending aortic graft replacement was carried out uneventfully. The patient is well 14 months postoperatively. Postoperative examinations following aortic surgery should be performed not only from the view point of cardiac function, but also from that of a pseudoaneurysm.

The purpose of this report is to clarify urologic problems in rural districts. The number of patients who visited our clinic for these 10 years were 7, 313 as new outpatient and 1802 as inpatient. Three main diseases of rural area were acute inflammation of lower urinary tract, benign prostatic hypertrophy and lithiasis of upper urinary tract. Infection of lower urinary tract and aggravation of malignant tumors might be influenced by rural works and bad circumstances. Monthly distribution of patients was also under the influence of rural works.

A case of combined redo off-pump CABG (OPCAB) with right gastroepiploic artery and abdominal aortic aneurysm repair is reported. A 71-year-old man with a previous history of CABG was admitted for the operation of recurrent angina pectoris and known abdominal aortic aneurysm. Preoperative coronary angiograms showed obstruction of LITA graft for LAD. The operative procedure consisted of redo OPCAB using right gastroepiploic artery as a transdiaphragmatic graft under left antero-lateral thoracotomy and graft replacement of abdominal aortic aneurysm under median laparotomy simultaneously. This strategy has the advantage of avoiding the continuity of median sternotomy and laparotomy and contributes to the minimally invasive procedure in the combined operation.

A 66-year-old woman complained of dyspnea due to congestive heart failure, and was given a diagnosis of severe aortic insufficiency. Antiphospholipid syndrome and idiopathic thrombocytopenic purpura (ITP) had been diagnosed with 9 years previously. We planned preoperative plasma exchange and steroid pulse infusion to reduce the level of auto-antibodies for phospholipids. The aortic valve replacement was performed safely. Anticoagulant therapy with low molecular weight heparin and oral steroid therapy was administered after the operation to avoid thrombosis or bleeding. The patient's postoperative course was stable. She was discharged without any complication. In conclusion, preoperative plasma exchange and steroid pulse infusion, postoperative anticoagulant therapy and oral steroids resulted in a favorable outcome in a case of heart surgery for a patient with antiphospholipid syndrome.

Lambl's excrescences are the fibrous structures which are attached to the heart valve, and usually the presence of Lambl's excrescences alone is not an indication of operation. The operative indications of isolated Lambl's excrescence is still controversial, because some reports indicated cross relationship between Lambl's excrescences and cerebral embolism. Based on these facts, we discussed our 3 cases of Lambl's excrescences. Two of the cases had been complicated with severe mitral regurgitation and Lambl's excrescences were resected at the time of mitral valve plasty. In another case, Lambl's excrescence was found with echocardiography during chronic heart failure therapy. This patient had a past history of cerebral infarction, but no relationship of cerebral infarction was suggested. In this case, cardiac surgery was not required, so we followed isolated Lambl's excrescence without resection in this case. One operated case, which had infective endocarditis was suspected by echocardiography, had slighted inflammatory reaction but blood culture was negative. Diagnosis of Lambl's excrescence was made by histopathological examination. One report suggested that the cause of the cerebral infarction is not Lambl's excrescence itself but the thrombi around Lambl's excrescence. However, we hesitate to operate on isolated Lambl's excrescence. Based on some reports, it is useful to resect Lambl's excrescence when a concurrent cardiac operation is carried out to avoid cerebral embolic events.

The patient was 62-year-old woman was brought to the emergency room with chest pain and dyspnea. Computed tomography revealed a hematoma around the ascending aorta, a notch in the aortic wall, pericardial effusion and a hematoma around the pulmonary artery. We diagnosed early thrombotic type of acute aortic dissection. An ascending aorta replacement was performed via median sternotomy under hypothermic circulatory arrest. Upon operation, there was a 1.0 cm intimal tear just above the left main trunk and there was no specific evidence of aortic dissection. So we diagnosed spontaneous aortic rapture. Her postoperative course was uneventful and she was discharged 18 days after surgery.

BACKGROUNDEstrogen receptor alpha (ER alpha) is the most important endocrine therapy responsiveness predictor for women with breast cancer. The accuracy of the prediction of the response to endocrine therapy was thought to be affected by involving the estrogen receptor coregulatory proteins and cross-talk between ER and other growth factor-signaling networks. Nuclear corepressor 1 (NCOR1) is one of the ER a transcription repressor. The objective of the study is to investigate the expression of NCOR1 at the protein level and pursue its predictive value for breast cancer endocrine therapy.
METHODSIn the present study, the level of expression of NCOR1 protein has been assessed by immunohistochemistry in 104 cases of invasive carcinoma of the breast. Associations between NCOR1 protein expression and different clinicopathological factors and survival were sought.
RESULTSIt was found that NCOR1 was expressed at significantly higher levels in responsive patients treated with endocrine therapy as first-line treatment on relapse. Responsive patients also had a significantly longer post-relapse survival and overall survival. No NCOR1 expression difference was found between patient by age, tumor size, lymph node status, different histological grade groups and human epidermal growth factor receptor 2 (HER2) status. Multivariate analysis showed that NCOR1 is an independent prognostic factor for over-all survival.
CONCLUSIONSIn breast cancer, NCOR1 protein expression level predicts response to endocrine therapy as first-line treatment for breast cancer patients on relapse and NCOR1 protein level assay may increase the accuracy in the endocrine treatment determination and, therefore, improving the patients survival.

BACKGROUND/AIMS: Few reports have described the long-term treatment outcomes of the anti-tumor necrosis factor-α antibody for Japanese Crohn’s disease (CD) patients. The aim of this study was to evaluate them and clarify the clinical factors that affect the long-term prognosis of the anti-tumor necrosis factor-α treatments. METHODS: This was a retrospective, observational, single-center cohort study. Japanese CD patients treated with either infliximab or adalimumab as a first-line therapy were analyzed. The cumulative retention rates of the biologics, relapse-free survival, and surgery-free survival were analyzed using Kaplan-Meier methods. The clinical factors associated with the long-term outcomes were estimated by both the log-rank test and Cox proportional hazard model. RESULTS: The cumulative retention rate was significantly higher in the group with a concomitant elemental diet of ≥900 kcal/day, baseline C-reactive protein (CRP) levels < 2.6 mg/dL, and baseline serum albumin levels ≥3.5 g/dL, respectively. The baseline serum albumin levels were also associated with both relapse-free and surgery-free survival. The lack of concomitant use of an elemental diet ≥900 kcal/day was identified as the only independent risk factor for the withdrawal of the biologics. CONCLUSIONS: Baseline CRP levels and serum albumin levels could affect the long-term outcomes in CD patients. Concomitant elemental diet of ≥900 kcal/day could have a positive influence on clinical treatment course.

A 71-year-old man underwent a medical checkup at another hospital with principal complaint of chest discomfort, and was diagnosed by computed tomography (CT) to have a left subclavian artery aneurysm. The CT revealed a 33-mm saccular aneurysm that was located at the proximal portion of the left subclavian artery. Because of the high risk of surgery, we planned to insert a stent graft into the left subclavian artery. We could not avoid occluding the ostium of the left vertebral artery with commercially-available stent grafts, and so decided to insert a surgeon-modified stent graft, in which the fabric of the distal portion of the stent graft was stripped away. The surgeon-modified stent graft was inserted from the conduit of the left axillary artery. Postoperative course was uneventful and the postoperative examination confirmed complete exclusion of the aneurysm and patency of the left vertebral artery.

We report two cases with postoperative sternal osteomyelitis after coronary artery bypass graft (CABG), in whom successful two-stage reconstruction was performed via negative pressure wound therapy (NPWT) and pectoralis major myocutaneous flaps. Two patients underwent CABG using bilateral internal thoracic arteries, after which they had surgical site infection (SSI). The intractable wound did not heal with irrigation and NPWT. Then, sternal osteomyelitis was observed via magnetic resonance imaging (MRI), so we planned two-stage reconstruction. The first stage of treatment consisted of complete debridement (including removal of sternal wires and necrosectomy of soft tissue and sequestrum) and application of NPWT until the remission of inflammation. The second stage consisted of wound closure with pectoralis major myocutaneous advancement flaps. After wound closure, the two patients were given 2 months of oral antibiotics, and the postoperative results were good. Two-stage reconstruction with NPWT and pectoralis major myocutaneous flaps results in excellent clinical outcome. In the first stage, the key to the successful management of postoperative sternal osteomyelitis is infection control. This includes surgical debridement and wound-bed preparation with NPWT. The pectoralis major myocutaneous flap technique is brief and does not require a second cutaneous incision or an intact internal thoracic artery. In conclusion, the pectoralis major myocutaneous flap is a useful option in two-stage reconstruction after CABG.
