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 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.

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.

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.

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.

Background/Aims: We aimed to clarify the clinicopathological characteristics and causes of Barrett’s esophageal adenocarcinoma (BEA) with unclear demarcation. Methods: We reviewed BEA cases between January 2010 and August 2022. The lesions were classified into the following two groups: clear demarcation (CD group) and unclear demarcation (UD group). We compared the clinicopathological findings between the two groups. Furthermore, we measured the length and width of the foveolar structures, as well as the width of marginal crypt epithelium (MCE). Results: We analyzed data from 68 patients with BEA, including 47 and 21 in the CD and UD groups, respectively. Multivariate analysis revealed long-segment Barrett’s esophagus (LSBE) as the sole significant risk factor for BEA (odds ratio, 12.17; 95% confidence interval, 2.84–47.6; p=0.001). Regarding pathological analysis, significant differences were observed in the length and width of the foveolar structure between cancerous and surrounding mucosa in the CD group (p=0.03 and p=0.00, respectively); however, no significant difference was observed in the UD group (p=0.53 and p=0.72, respectively). Nevertheless, the width of MCE in the cancerous area was significantly shorter than that in the surrounding mucosa in both groups (p<0.05, and p<0.05, respectively). Conclusions LSBE is a significant risk factor for BEA in the UD group. The width of MCE may be an important factor in the endoscopic diagnosis of BEA.

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.
