Nutritional support for patients who develop cancer is necessary to increase their food intake, which is often insufficient due to the adverse effects of anticancer drugs and radiation treatment. In December 2011, our center introduced Bocchiri meals for cancer patients to improve their quality of life and support ongoing treatment. In this study, we examined the efficacy of Bocchiri meals, which were developed to help increase the amount of food intake during cancer treatment. Target patients were those who could eat half or less than half of their daily required food intake, averaged over 3 days.Patients could order the meal 2 h before serving time and it was served at the temperature and amount that individual patients requested.We evaluated age, sex, main disease, use of anticancer drugs, radiation treatment, time taken to eat the Bocchiri meals, number of orders made, average energy intake before and after eating the Bocchiri meals, and rate of eating a Bocchiri Meal with a side menu order. Average energy intake was increased from 226.6±14.8 kcal with regular meals to 294.1±15.3 kcal with Bocchiri meals. Furthermore, a strong correlation was seen after the Bocchiri meals were introduced between the rate of eating Bocchiri meals with a side menu order and average energy intake. These results suggest that Bocchiri meals may be an effective supportive nutritional measure to enhance food intake among cancer patients.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease endemic in East Asia. Transmitted to other organisms by infected ticks, the SFTS virus (SFTSV) and is endemic to Nagasaki in western Japan. However, epidemiological information regarding SFTSV in Nagasaki ticks has not been available to date. In this study, we began by examining the sensitivities of SFTSV gene detection by real-time RT-PCR and virus isolation in cultured cells and mice. These methods could detect SFTSV in the samples containing more than 4 × 10⁰ ffu. Next, we attempted to isolate SFTSV and to detect viral gene in 2,222 nymph and adult ticks collected from May to August 2013 among seven regions of Nagasaki. However, neither virus isolation nor viral gene detection were confirmed in the tick pools. SFTSV positivity rates are considered to be very low in ticks, and viral loads are also very limited. Further investigations increasing the number of ticks and including larval samples as well as improved detection methods, may be required to find SFTSV-positive ticks in this region.

A 64-year-old man under dialysis was referred for surgical treatment of Crawford type I thoracoabdominal aortic aneurysm. He had a history of idiopathic portal hypertension and chronic total occulusion of supra-renal abdominal aorta and appeared to have massive development of collateral arteries and veins in the abdomen. We chose endovascular repair with debranching of visceral arteries and bypass grafting to bilateral superficial femoral artery considering bleeding from collateral arteries and veins by conventional open surgery. Postoperative CT scan revealed no endoleak and all debranched and bypass grafts were patent. He was discharged with no postoperative complications including paraplegia.

The left atrium and left atrial appendage have unique genetic anatomical and physiological features. Recently, advances in diagnostic imaging technology have provided much new knowledge. Clinically, the risk of developing atrial fibrillation increases with age. In order to reduce the public health burden such as cerebral infarction caused by atrial fibrillation, we need to find some predictive risk factors and preventive strategies for cerebral infarction and more effective treatments. The new concept of atrial myopathy has emerged, and animal models and human studies have revealed close interactions between atrial myopathy, atrial fibrillation, and stroke through various mechanisms. Structural and electrical remodeling such as fibrosis and deterioration of the balance of autonomic nerves and complicated interactions between these mechanisms lead to deterioration of atrial fibrillation and a continuous vicious cycle, and finally thrombosis in the left atrial appendage. Although anticoagulant therapy for patients with atrial fibrillation is strongly recommended, it is difficult for many patients to continue optimal treatment. In the nearly future, it will be important to understand the anatomy and physiology of the left atrial appendage and to understand the shape changes, size and the changes of autonomic function, and thrombus formation conditions associated with LAA remodeling during atrial fibrillation, and then we should provide early therapeutic intervention.

A 65-year-old man was referred to our hospital in April 2003 with a pancreas tumor detected by a thorough medical checkup. Computed tomography (CT) showed swelling of the pancreatic body and tail, and magnetic resonance cholangiopancreatography (MRCP) showed only the main pancreatic duct in the head of the pancreas. Diagnosing autoimmune pancreatitis, we observed the patient without medication. However, one year later CT showed stenosis of the splenic artery and portal vein accompanied by development of collateral circulation around the pancreas. He had no symptoms, and CT showed no changes in the pancreatic swelling.;;He was admitted to our hospital on January 6, 2005, presenting with a history of jaundice which first appeared on January 1, 2005, and increased collateral circulation around the pancreas with pancreatic swelling were seen on CT. We started prednisolone therapy at 40 mg/day for exacerbation of autoimmune pancreatitis. Serum bilirubin levels improved from 11.9 mg/dl to 2.5 mg/dl, and pancreatic swelling also improved four weeks after starting therapy.;;We present a rare case of autoimmune pancreatitis that developed marked collateral circulations.

We have used two methods for education of pathology at the Yokohama City University School of Medicine: 1) clinicopathological conferences on autopsy cases and 2) journal club using “Case Records of the Massachusetts General Hospital” published in the New England Journal of Medicine. Both methods are extremely effective for stimulating students' enthusiasm for learning, improving presentation skills, and consolidating the minds of students as future medical staff members. Furthermore, journal club enhances the affinity for reading medical English.

OBJECTIVE: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease. METHODS: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease. RESULTS: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery. CONCLUSION: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium.

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.
