Introduction : Prevention of embolic stroke is the key issue to perform aortic arch replacement in patients with a shaggy aorta. The aim of this study is to report the utility of the isolation technique for total arch replacement in patients with a shaggy aorta. Methods : Clinical results of seven patients (71.7 years old, all men) with a shaggy aorta who underwent total arch replacement between January 2017 and November 2018 were retrospectively reviewed. The operative indications were a distal arch or proximal descending aortic aneurysm in 6 patients and a thrombus inside brachiocephalic artery in one. A cerebral perfusion was established by inserting a cannula directly into all supra-aortic branches before starting systemic perfusion. Result : Utilizing the isolation technique with clamping of all branches in 4 patients and the functional isolation technique with clamping of two branches in 3, total arch replacement was performed in all patients (operation time : 513 min, selective cerebral perfusion time : 162 min). No operative death was observed and no newly developed stroke was encountered. Conclusion : The isolation technique is a useful method to prevent stroke during total arch replacement in patients with a shaggy aorta.

We present a 62-year-old woman who was diagnosed with primary pulmonary arterial sarcoma with pulmonary hypertension. CT showed a large defect inside both main pulmonary arteries in accordance with the accumulation of FDG-PET. To relieve the symptom and to prevent sudden death, removal of a massive pulmonary tumor and postoperative chemotherapy were planned. Utilizing the intermittent systemic circulatory arrest under deep hypothermia (18°C), the pulmonary artery trunk and both main pulmonary arteries were opened. The tumor stacking inside the pulmonary artery was removed and its origin at the commissure of the pulmonary artery valve was resected. The defect was repaired with a pulmonary valve replacement. Histopathological examination revealed high grade sarcoma. Her postoperative course was uneventful ; however, she died of cerebral hemorrhage during chemotherapy six months after surgery.

Purpose: Naldemedine is a peripheral µ-opioid receptor antagonist, including the treatment of opioid-induced constipation (OIC) . However, diarrhea is known as its side effect. We conducted a study focusing on the administration period of opioid analgesics before the start of naldemedine to clear predictors of diarrhea due to Naldemedine. Method: All data were retrospectively collected from the electronic medical record system. We investigated patients who initially administrated naldemedine at Nagasaki University Hospital from June 1 2017 to March 31 2019. Result: One hundred thirty-two patients were subject of investigation. The incidence of diarrhea was 25.0%. The result of the multivariate analysis showed that significant predictors of diarrhea were associated with the opioid analgesics usage period longer than 7 days before naldemedine initiation (odds ratio: 3.76, 95% confidence interval: 1.53-9.20, p=0.004). Discussion: When naldemedine was used for OIC, diarrhea may be avoided by using within 7 days after opioid analgesics.

The background and course of Kampo treatment in 39 patients with uncontrollable otolaryngeal symptoms treated between April 2013 and March 2016, in the Department of Kampo Medicine at Tohoku University Hospital, were analyzed retrospectively. An improvement in overall symptoms was noted with Kampo treatment in 28 of 39 cases (71%). The commonly reported subjective symptoms included glossodynia (7 cases), postnasal drip (4 cases), oral discomfort (4 cases), dizziness (3 cases), and taste disorder (3 cases). Analysis using the classification of qi, blood, and fluid revealed that cases with qi stagnation pattern (15 of 18 cases) were effectively treated with Kampo treatment. Prior reports support our finding that smoothing qi with Kampo medicine is effective in alleviating some chronic symptoms. The symptoms improved within 6 weeks after the treatment was initiated. Therefore, a 6-week period can be considered sufficient to determine the effectiveness of Kampo medicine. Many of the patients for whom Kampo treatment was not effective had depression and domestic stress. In conclusion, Kampo treatment may be effectively used to treat uncontrollable, chronic otolaryngeal symptoms in selected cases that are unresponsive to Western medicine.

OBJECTIVE: Recent investigations have revealed DNA mismatch repair (MMR) gene mutations are closely related with carcinogenesis of endometrial cancer; however the impact of MMR protein expression on prognosis is not determined. Correlations between MMR-related protein expression and clinicopathological factors of endometrial cancers are analyzed in the present study. METHODS: A total of 191 endometrial cancer tissues treated between 1990 and 2007 in our hospital were enrolled. Immunoreactions for MSH2, MLH1, MSH6, and PMS2 on tissue microarray specimens and clinicopathological features were analyzed retrospectively. RESULTS: Seventy-six cases (40%) had at least one immunohistochemical alteration in MMR proteins (MMR-deficient group). There were statistically significant differences of histology, International Federation of Gynecology and Obstetrics (FIGO) stage, and histological grade between MMR-deficient group and the other cases (MMR-retained group). Response rate of first-line chemotherapy in evaluable cases was slightly higher in MMR-deficient cases (67% vs. 44%, p=0.34). MMR-deficient cases had significantly better progression-free and overall survival (OS) compared with MMR-retained cases. Multivariate analysis revealed MMR status was an independent prognostic factor for OS in endometrial cancers. CONCLUSION: MMR-related proteins expression was identified as an independent prognostic factor for OS, suggesting that MMR was a key biomarker for further investigations of endometrial cancers.

OBJECTIVE: Compared with serous adenocarcinoma (SAC), clear cell carcinoma (CCC) often shows chemo-resistance, which would potentially lead to a poor prognosis. On the other hand, there have been arguments over prognoses of CCC and SAC disease. In the present study, multivariate analysis to compare prognosis of CCC patients with that of SAC was aimed for the patients selected from central pathologic review. METHODS: Between 1984 and 2009, a total of 500 ovarian cancer patients were treated at our university hospital. Among them, 111 patients with CCC and 199 patients with SAC were identified through central pathological review. Overall survival and progression-free survival were compared using Kaplan-Meier method, and prognostic factors were investigated by multiple regression analyses. RESULTS: Median age was 52 years for CCC and 55 years for SAC (p=0.03). The ratio of stage I patients were significantly higher in CCC compared with SAC (55% vs. 13%, p<0.01). Among evaluable cases, response rate was significantly lower in CCC than that in SAC (32% vs. 78%, p<0.01). No significant differences of progression-free survival and overall survival were observed in stage I patients; however, prognoses of CCC were significantly poorer than those of SAC in advanced-stage disease. In stage II-IV patients, not only residual tumors and clinical stages, but also clear cell histology were identified as predictors for poor prognosis. CONCLUSION: Clear cell histology was identified as a prognostic factor for advanced-stage ovarian cancers. Histologic subtypes should be considered in further clinical studies, especially for advanced epithelial ovarian cancers.

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.

An 84-year-old man with a thoracic aortic aneurysm underwent total arch replacement with selective antegrade cerebral perfusion. Immediately after the operation, respiratory distress and hypotension developed and Chest X-ray films and computed tomography showed bilateral lung edema. Echocardiography showed a small, underfilled left ventricle, but with preserved systolic function. We suspected transfusion-related acute lung injury (TRALI), and started sivelestat and steroid pulse therapy. His respiratory condition gradually improved, and he was discharged on postoperative day 78. The diagnosis of TRALI was confirmed by positive test results of an HLA class I antibody in the transfused fresh frozen plasma and T- and B-cells of the patient. TRALI should be considered as a cause of acute lung injury after surgery with blood transfusion.

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.

A compulsory postgraduate clinical training system, which includes psychiatry as a requirement, will be started in 2004. However, many problems have been pointed out and discussed. In this report we offer 2 suggestions for making clinical training more useful. First, new residents should study not only psychiatric knowledge but also the attitudes of psychiatrists toward patients. Second, we psychiatrists should determine the practical requirements for the training of new residents. In such suggestions are implemented, Japanese psychiatry may change for the better.
