A 62-year-old man presented with hemoptysis and hoarseness. He was diagnosed with an aortopulmonary fistula due to a thoracic aortic aneurysm rupture and was referred to our department. Emergency in-situ reconstruction of the aorta and pulmonary lobectomy were performed. Nine days postoperative, he developed empyema. Intrapleural urokinase and antibiotic therapy were selected as management instead of a video-assisted thoracoscopic debridement and decortication due to his worsening condition. The treatment was successful, and he was discharged from the hospital without any further complications. This study highlights the benefit of intrapleural administration of urokinase and antibiotics in patients with acute empyema, when surgical treatment is inappropriate.

The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract cancers (cholangiocarcinoma, gallbladder cancer, and ampullary cancer) in 2007, then published the 2nd version in 2014. In this 3rd version, clinical questions (CQs) were proposed on six topics. The recommendation, grade for recommendation, and statement for each CQ were discussed and finalized by an evidence-based approach. Recommendations were graded as grade 1 (strong) or grade 2 (weak) according to the concepts of the grading of recommendations assessment, development, and evaluation system. The 31 CQs covered the six topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, and (6) radiation therapy. In the 31 CQs, 14 recommendations were rated strong and 14 recommendations weak. The remaining three CQs had no recommendation. Each CQ includes a statement of how the recommendations were graded. This latest guideline provides recommendations for important clinical aspects based on evidence. Future collaboration with the cancer registry will be key for assessing the guidelines and establishing new evidence.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory disease of the gastrointestinal tract, with increasing prevalence worldwide. IBD Ahead is an international educational program that aims to explore questions commonly raised by clinicians about various areas of IBD care and to consolidate available published evidence and expert opinion into a consensus for the optimization of IBD management. Given differences in the epidemiology, clinical and genetic characteristics, management, and prognosis of IBD between patients in Japan and the rest of the world, this statement was formulated as the result of literature reviews and discussions among Japanese experts as part of the IBD Ahead program to consolidate statements of factors for disease prognosis in IBD. Evidence levels were assigned to summary statements in the following categories: disease progression in CD and UC; surgery, hospitalization, intestinal failure, and permanent stoma in CD; acute severe UC; colectomy in UC; and colorectal carcinoma and dysplasia in IBD. The goal is that this statement can aid in the optimization of the treatment strategy for Japanese patients with IBD and help identify high-risk patients that require early intervention, to provide a better long-term prognosis in these patients.

The education program in all medical schools in Japan has been studied and analyzed every 2 years since 1974 by the curriculum committee of the Association of Japan Medical Colleges. Based on the most recent analysis in 2015, the marked innovation of medical education, such as an integrated curriculum, active learning, and clinical clerkship, was recognized.

Proteases play important roles in parasite development and host parasite interactions. The protease of Kudoa spp. has been recognized as a key factor of severe proteolysis of fish muscle post-mortem; however, there is little information available regarding the protease of Kudoa (K.) septempunctata, which was recently identified as a cause of food poisoning in humans. The present study was conducted to isolate and characterize proteases to elucidate the type of protease contained in the parasite and determine the optimal pH for protease activity. We confirmed the cysteine protease and metalloprotease produced by K. septempunctata. While the cysteine protease showed optimal activity at pH 5 that decreased rapidly with increasing pH, the optimal activity of metalloprotease was pH 7, and it remained stable from pH 6 to pH 8. These results indicate that the pH of cysteine protease is not proper for fish muscle postmortem, and that metalloprotease can act in human intestines. Overall, the present study provides important information that improves our understanding of the role of protease physiology and the subsequent food poisoning caused by K. septempunctata.

Objective : Serum albumin is important marker in all aspects of stroke care including rehabilitation. We examined the serum albumin level of stroke patients, and investigated the relation between their serum albumin level and their prognosis. Methods : The serum albumin levels of 295 patients enrolled from 2008 to 2014 were sequentially checked in our hospital and in subsequent rehabilitation hospitals. Functional outcome was measured by functional independence measure (FIM) at the time of discharge from the rehabilitation hospital. Results : In all types (cerebral infarction, cerebral hemorrhage and subarachnoid hemorrhage (SAH)) of apoplexy, serum albumin levels were the highest at the time of admission, temporarily declined after admission, and almost recovered at the time of discharge. In SAH, the serum albumin levels deteriorated at a greater rate than in other types of stroke. In cerebral infarction and cerebral hemorrhage, the lowest serum albumin level was positively correlated with FIM at the time of discharge from the rehabilitation hospital (p<0.001). But, in SAH, there was no significant correlation between the lowest serum albumin level and FIM at the time of discharge (p=0.844). Conclusion : Our data suggest that serum albumin level is associated with the outcome of stroke patients, except for SAH patients. Serum albumin level should be one of the prognostic factors used in stroke patients, but we should consider that SAH patients are exceptional because of other neurological complications.

There is Bartonella henselae (B. henselae) leads to cat-scratch disease and causes infective endocarditis, but shows as negative in blood cultures. We performed aortic valve replacement in a patient with aortic valve infective endocarditis which was regative on blood cultures. The patient had a contact history with a cat prior to admission. Thus, we suspected B. henselae and made a definitive diagnosis by PCR method and Warthin-Starry (WS) stain. A correct diagnosis was possible by detailed history taking and the use of appropriate antibiotics.

We describe two cases of a 9-day-old male and a 5-year-10-month-old female who had congestive heart failure due to severe mitral regurgitation. Preoperative echocardiogram revealed severe mitral regurgitation due to dysplasia of the leaflet, chordae and papillary muscle. Because the leaflet area was not enough for the valve orifice, we performed double orifice repair by suturing the free edge to the corresponding edge of the opposite leaflet. The mitral regurgitation was found to be significantly reduced on postoperative echocardiogram. Double orifice repair is simple and can be performed rapidly. However, although this technique has been performed in adults, it has not been commonly performed in infants. Our results suggest that this procedure can be useful for the congenital mitral regurgitation. Long-term follow-up is needed to confirm the result.

A 9-year-old boy with multisaccular thoracic aortic aneurysm associated with coarctation of the aorta underwent definitive repair under partial cardiopulmonary bypass. The operation consisted of resection of the aneurysm and reconstruction of the descending aorta. Aortic reconstruction was done without an artificial graft, and extended end-to-end anastomosis was performed successfully. He has been doing well and there was no significant restenosis at the repair site 5 years after the operation. Some authors reported that untreated coarctation of the aorta frequently developed aneerysm, which usually has multisaccular lesions. Surgical strategy of aortic reconstruction for coarctation of the aorta in boyhood should be decided prudently to avoid postoperative complications.
