Abstract
Osteosarcoma is a malignant tumor in which the cancerous cells produce an osteoid matrix or mineralized bone. Jaw bones are affected in 6% of all osteosarcomas and are the fourth most common site of origin. Surgical treatment of osteosarcoma in elderly patients is rarely reported. Here, we report successful treatment of osteosarcoma arising in the mandible of a 90-year-old man. The patient was referred to our institution for diagnosis and treatment of an oral lesion. Intraoral examination revealed that a hard mass measuring 35 × 27 mm was located on the floor of the oral cavity, attached to the bone, and its growth displaced the tongue posteriorly. Therefore, he experienced difficulty in speech and swallowing. Biopsy of the mandibular mass was suspicious for chondrosarcoma. Preoperative examination did not detect critical risks for general anesthesia or surgery. Based on a clinical diagnosis of a malignant bone tumor of the mandible, segmental mandibular resection with reconstruction using a titanium plate was performed. Surgical site infection occurred on postoperative day 12, which was resolved by drainage, local irrigation, and administration of antibiotics. There was no delirium or cardiovascular or pulmonary complications. Surgery resolved the patient's difficulties in speech and swallowing. There was no evidence of tumor recurrence or metastasis 4 years after surgery. This case showed that it was not necessary to exclude surgical treatment merely because the patient was 90 years old. Indications for surgery should be determined individually to improve the patient's quality of life.

Abstract
Mandibular reconstruction using a titanium mesh tray and autologous bone is a common procedure in oral and maxillofacial surgery. However, there can be material problems-such as broken titanium mesh trays-which may undermine long-term functionality. This study was designed to investigate the optimal conditions for a titanium mesh tray with an ideal mandibular shape and sufficient strength, using computer-aided design, computer-aided manufacturing technology, and electron beam additive manufacturing. Specimens were prepared using Ti-6Al-4V extra low interstitial titanium alloy powder and an electron beam melting (EBM) system. The mechanical strength of the plate-shaped specimens was examined for differences in the stretch direction with respect to the stacking direction and the presence or absence of surface treatment. While evaluating the mechanical strength of the tray-shaped specimens, the topology was optimized and specimens with a honeycomb structure were also verified. Excellent mechanical strength was observed under the condition that the specimen was stretched vertically in the stacking direction and the surface was treated. The results of the tray-shaped specimens indicated that the thickness was 1.2 mm, the weight reduction rate was 20%, and the addition of a honeycomb structure could withstand an assumed bite force of 2000 N. This study suggests that the EBM system could be a useful technique for preparing custom-made titanium mesh trays of sufficient strength for mandibular reconstruction by arranging various manufacturing conditions.

Abstract
Ramucirumab monotherapy is one of the conditionally recommended regimens in second-line chemotherapy for advanced gastric cancer. However, there are few clinical data on ramucirumab monotherapy in Japanese patients. Herein, we present 4 case reports of advanced gastric cancer patients who received ramucirumab monotherapy. The 4 patients' age ranged from 65-81 years old(median: 70 years old), with a 3:1 male to female ratio. Since all cases were in poor performance status, administration of cell-killing anticancer drugs such as paclitaxel was contraindicated, and ramucirumab monotherapy was selected as an alternative. Ramucirumab was administrated 2-8 times(median: 3 times), resulting to a stable disease in 1 patient, and progression-free survival was noted to be 3-16 weeks(median: 5 weeks). Regarding complications, Grade 2 hypertension occurred in 1 patient, and no serious adverse events were observed. Ramucirumab monotherapy is a well-tolerated second-line chemotherapy for patients with advanced gastric cancer in poor performance status, and it is expected to have some disease control effect.

Abstract
CONTEXT Results of previous studies demonstrated clear racial differences in the prevalence of somatic mutations among patients with aldosterone-producing adenoma (APA). For instance, those in East Asian countries have a high prevalence of somatic mutations in KCNJ5, whereas somatic mutations in other aldosterone-driving genes are rare. OBJECTIVES To determine somatic mutation prevalence in Japanese APA patients using an aldosterone synthase (CYP11B2) immunohistochemistry (IHC)-guided sequencing approach. METHOD Patients with a unilateral form of primary aldosteronism who underwent adrenalectomy at the Tohoku University Hospital were studied. Based on CYP11B2 immunolocalization of resected adrenals, genomic DNA was isolated from the relevant positive area of 10% formalin-fixed, paraffin-embedded tissue of the APAs. Somatic mutations in aldosterone-driving genes were studied in APAs by direct Sanger sequencing and targeted next-generation sequencing. RESULTS CYP11B2 IHC-guided sequencing determined APA-related somatic mutations in 102 out of 106 APAs (96%). Somatic KCNJ5 mutation was the most frequent genetic alteration (73%) in this cohort of Japanese patients. Somatic mutations in other aldosterone-driving genes were also identified: CACNA1D (14%), ATP1A1 (5%), ATP2B3 (4%), and CACNA1H (1%), including 2 previously unreported mutations. KCNJ5 mutations were more often detected in APAs from female patients compared with those from male patients [95% (36/38) vs 60% (41/68); P < 0.0001]. CONCLUSION IHC-guided sequencing defined somatic mutations in over 95% of Japanese APAs. While the dominance of KCNJ5 mutations in this particular cohort was confirmed, a significantly higher KCNJ5 prevalence was detected in female patients. This study provides a better understanding of genetic spectrum of Japanese APA patients.

Abstract
Radiation esophagitis requiring endoscopic evaluation occurs quite rarely, affecting <1% of patients undergoing radiation treatment. Acute radiation esophagitis develops within 3 weeks of radiation therapy. We describe herein a case of radiation esophagitis in a patient with oral carcinoma with multiple general bone metastases. Cisplatin, fluorouracil, and cetuximab were given for 3 cycles. Radiation therapy (30 Gy) to the thoracic vertebrae and lumbar vertebrae was prescribed to prevent worsening of bone metastases and relieve pain. Neutropenia was also observed due to chemotherapy. After the end of radiation therapy, the patient experienced chest pain, heartburn, and dysphagia. Upper gastrointestinal endoscopy revealed severe radiation esophagitis of endoscopic Fukui Acute Radiation Esophagitis grade 4. Oral food was discontinued and an intravenous proton-pump inhibitor was administered. After 3 weeks, upper gastrointestinal endoscopy showed improvement of radiation esophagitis, with scars. The symptoms of chest pain, heartburn, and dysphagia had also disappeared. This is the first case to be reported of acute radiation esophagitis in a patient with oral carcinoma with bone metastasis who experienced dramatic improvement of endoscopic findings. Neutropenia appears to be associated with more severe acute radiation esophagitis.

Abstract
Cystadenoma is a rare benign salivary gland neoplasm characterized by a predominantly multicystic growth pattern. The parotid gland is involved in about 45–50% of cystadenoma cases, with the minor glands of the lip and buccal mucosa being the next most common sites. The tongue is rarely involved; only one congenital case is reported in the literature. Here, we report a 63-year-old man who was referred to our hospital for a nodule on the right edge of his tongue that developed into an elastic soft mass, 4 mm in diameter. It was clinically diagnosed as a benign tumour and removed under local anaesthesia. Microscopically, the lesion was composed of multiple cysts of various sizes and shapes, with or without papillary intraluminal short projections. It was diagnosed as cystadenoma. The postoperative course was uneventful, and we found no evidence of recurrence at the postoperative 14-year follow-up.

Abstract
BACKGROUND The symptoms of hypopituitarism are not usually discussed in the clinical setting of oral surgery. CASE PRESENTATION We herein report a case of hypopituitarism that became evident after biopsy and extraction of several teeth in a 68-year-old man with tongue cancer. Three days after biopsy, the patient developed nausea and vomiting, and his serum sodium had fallen to 124 mEq/L. His serum cortisol concentration was low. Although the plasma concentration of adrenocorticotropic hormone (ACTH) was within the normal range, ACTH stimulation testing showed a lack of cortisol response. Given these findings, we suspected secondary adrenal insufficiency. To investigate the cause of secondary adrenal insufficiency, MRI of the head was performed, which revealed pituitary gland atrophy. The results of pituitary anterior lobe hormone-stimulation tests were compatible with hypopituitarism. Thirty days after biopsy, partial tongue resection was successfully performed under general anesthesia with perioperative hydrocortisone supplementation. CONCLUSIONS We must be aware of various signs of hypopituitarism when we perform invasive dental treatment.

Abstract
Background/Aims Fundic gland polyps (FGPs), hyperplastic polyps (HPs), and xanthomas (XTs) are common benign gastric lesions that can be diagnosed by endoscopic appearance alone in most cases. The aim of this study was to evaluate associations between gastric cancer and these benign lesions. Methods Two expert endoscopists reviewed a series of gastroscopy images. FGPs, HPs, and XTs were diagnosed by endoscopic appearance, whereas all gastric cancers were confirmed pathologically. Results Of the 1,227 patients reviewed, 114 (9.3%) had a concurrent or past history of gastric cancer. The overall prevalences of FGPs, HPs and XTs were 9.4%, 6.3% and 14.2%, respectively. HPs and XTs coexisted in 1.6% of patients, whereas other combinations were rarer. XTs were observed in 39.3% and 11.5% of patients with and without gastric cancer, respectively (p<0.001). In contrast, no gastric cancer patients had FGPs, whereas 10.4% of patients without cancer had FGPs (p<0.001). The prevalence of HPs was similar between the two groups (8.8% and 6.0% of patients with and without cancer, respectively, p=0.29). Multivariate and Mantel-Haenszel analyses demonstrated that XTs were positively associated and FGPs were negatively associated with gastric cancer. Conclusions XTs and FGPs might be useful as endoscopic risk indicators for monitoring gastric cancer.

Abstract
Recent advances of molecular analysis and the development of specific monoclonal antibody against aldosterone synthase (CYP11B2) have indeed established the histological subtypes based on the localization of aldosterone overexcess and revealed the association between genotype and clinicopathological phenotype. In particular, several kinds of aldosterone-driver gene somatic mutation have been reported, including KCNJ5, ATP1A1, ATP2B3, CACNA1D and CTNNB1. Among them, KCNJ5 somatic mutation was most frequently detected in aldosterone-producing adenoma although the prevalence of PA genotypes was markedly different among ethnic groups. The precise prevalence of genotype and histological subtypes in Japanese PA patients in large cohort has virtually remained unknown. Therefore, in this study, consecutive 125 unilateral PA cases entirely composed of Japanese patients who underwent surgery from 2012 to 2017 were histologically and genetically evaluated in order to clarify the precise prevalence of genotypes and histological subtypes among Japanese PA patients. 125 cases were precisely classified as follows based on detailed histopathological examination; single APA (84.0%), multiple (more than two) APAs (1.6%), APA + NFA (non-functional adenoma) (5.6%), MN (multiple adrenocortical micronodules) (5.6%), MN+NFA (2.4%) and DH (diffuse hyperplasia of the zona glomerulosa) (0.8%). Adrenal glands harboring single APA were further examined for genotyping. Among them, 67% harbored KCNJ5 mutated (G151R: 39.6%, L168R: 26.4%, T158A: 1.1%) and 33% harbored wild type. 5.4% of single APA clinically combined with Subclinical Cushing's syndrome, all harbored KCNJ5 mutated APAs. The results of our large-scaled analysis did firstly reveal the precise prevalence of histological subtypes and genotypes among Japanese PA patients who underwent surgery. Approximately 10% of unilateral resected PA cases histologically harbored non-neoplastic subtypes such as MN and DH. In addition to those non-neoplatic subtypes, 15% of unilateral resected PA cases other than single APA definitely required CYP11B2 immunohistochemistry in order to precisely detect the responsible lesions for aldosterone overexcess, distinguishing from the non-functional adrenocortical lesions or/and detecting more than two responsible lesions.

Abstract
Paraganglioma and pheochromocytoma are rare neuroendocrine neoplasms that originate from chromaffin cells. In many of these tumors, several mutations are reported to occur in the genes of germline and/or somatic cells. A case of paraganglioma in the posterior mediastinum with highly malignant potential is reported. The patient had a rapid clinical course, and it was difficult to reach the final diagnosis. The initial diagnosis on fine-needle aspiration biopsy was a gastrointestinal stromal tumor (GIST) arising from the esophagus. Although radiation therapy was effective for the main tumor, the lung metastases did not respond sufficiently to several tyrosine kinase inhibitors. Autopsy and immunohistochemical examination using a battery of different markers resulted in a final diagnosis of malignant paraganglioma. Next-generation sequencing revealed several gene mutations and copy number variations, including of fumarate hydratase (FH), neurofibromatosis type-1 (NF1) and RET. Those gene alterations may contribute to the pathogenesis of this malignant phenotype to a certain extent. To confirm this, further cases and studies are required. In addition, it should be noted that histological examination of a small piece of tumor might have sampling bias and could cause misdiagnosis.

Abstract
Objective to re-examine measures to prevent oral mucositis caused by drugs in head and neck cancer patients during cancer treatment by measuring salivary excretion of 5-fluorouracil. Saliva, blood, and urine were simultaneously collected from oral cancer patients and breast cancer patient at the point in time of before, during, and after the administration of 5-FU, then the 5-FU levels of the samples were quantitatively analysed using LC-MS/MS. In all patients, the 5-FU levels in saliva and serum peaked at 30 min to 3 h after the start of 5-FU treatment, and high levels were maintained throughout the administration of the drug. With regard to urinary 5-FU levels, they remained high from 3 to 120 h after the start of 5-FU treatment. After the completion of 5-FU treatment, even though it not appeared in the patients’ serum and urine promptly, 5-FU was detected in saliva at 12 h after the completion of 5-FU treatment in one oral cancer patient and at 48 h after the completion of 5-FU treatment in the breast cancer patient. It was suggested that the level of hydration after the completion of chemotherapy may be involved in the differences in 5-FU excretion.

Abstract
Objective The complication of systemic immunoglobulin light chain (AL) amyloidosis in patients with monoclonal immunoglobulin affects the prognosis, but amyloid deposition in tissues is sometimes difficult to detect due to bleeding tendencies and preferential distributions. However, fibrinolysis is known to be exacerbated in patients with systemic AL amyloidosis specifically. We therefore explored new biomarkers for predicting a diagnosis of systemic AL amyloidosis focusing on coagulation and fibrinolysis markers. Methods We reviewed the clinical features and treatment outcomes of patients with serum monoclonal protein, including primary systemic AL amyloidosis and multiple myeloma (MM), treated at our hospital between January 2008 and December 2014. Results Among several biomarkers, only the serum level of plasmin-α2-plasmin inhibitor complex (PIC) in patients with systemic AL amyloidosis (n=26) at the diagnosis was significantly higher than in patients with MM without AL amyloidosis (n=26) (mean±standard deviation, 3.69±2.82 μg/mL vs. 1.23±0.97 μg/mL, p<0.01). The cut-off for predicting a diagnosis of systemic AL amyloidosis in patients with serum monoclonal protein was 1.72 μg/mL with 84.6% sensitivity and 80.8% specificity. Hepatic involvement resulted in a significantly higher PIC level than no involvement in patients with systemic AL amyloidosis. The serum PIC level was also associated with the hematological response of systemic AL amyloidosis. Conclusion PIC is a useful biomarker for the diagnosis and management of patients with systemic AL amyloidosis.

Abstract
AIM Interval gastric cancers (IGC) are defined as those diagnosed after negative results of endoscopy carried out within the past 10 years. We aimed to investigate the characteristics of IGC and the natural history of gastric cancer (GC) from a retrospective view of endoscopic images of older patients with IGC. METHODS We retrospectively reviewed endoscopic images of 240 patients with GC who were aged >60 years. We compared past endoscopic images with newer ones, in which GC was diagnosed. IGC were classified into two categories: missed cancers and new cancers. RESULTS Of the 240 patients with GC, 32 had past endoscopic images that qualified for a precise review. A total of 14 cases involved new cancers, whereas 18 involved missed cancers. Most of the IGC were stage I for at least 2 years; however, a small subset was unresectable at >2 years after a negative endoscopy. Furthermore, the rate of endoscopic treatment was significantly higher for IGC compared with that for non-IGC. CONCLUSIONS In people aged >60 years, most IGC remain in an early stage for at least 2 years; however, at >2 years after a negative endoscopy, some are unresectable. These results suggest that most early-stage GC will not develop into advanced cancers within 2 years; thus, a 2-year interval might be within the permissible range for patients with negative endoscopy results for any lesions.

Abstract
A 62-year-old man with a chief complaint of dysphagia visited our hospital. Enhanced computed tomography showed the tumor near the duodenal wall and lymphadenopathy in the left supraclavicular fossa and para-aortic lymph node. Upper gastrointestinal endoscopy showed an ulcer accompanied with a fistula in the anterior wall of duodenal bulb, suggesting that the tumor penetrated into duodenal wall. Biopsy from the lymph node in the left supraclavicular fossa indicated diffuse large B-cell lymphoma. Although chemotherapy was planned, massive arterial bleeding occurred from the part of duodenal penetration. Endoscopic hemostasis was unsuccessfully performed. Therefore, we performed transcathether arterial embolization for hemostasis. After the procedure, the patient received six cycles of chemotherapy, and he achieved complete response. He has been alive 5 years without recurrence. There were many cases of gastrointestinal bleeding from primary gastrointestinal lymphomas, while there were few cases with nodal involvement by malignant lymphoma resulting in bleeding from gastrointestinal tract. We herein report a case of duodenal bleeding by nodal involvement of diffuse large B-cell lymphoma with review of literature.

Abstract
Background and study aims Ischemic proctitis is a rare disease and comprises 2 % to 5 % of cases of ischemic colitis, because the rectum has abundant blood supply and rich collaterals. Herein, we report a case of a 73-year-old male patient with a pronounced rectal stricture caused by ischemic proctitis resulting from an abdominal aortic rupture and treated by endoscopic balloon dilation therapy. To date, only 3 cases of rectal stricture related to ischemic proctitis including our case have been reported, and this is the first case of rectal stricture related to ischemic proctitis, which was successfully treated by endoscopic balloon dilation.

Abstract
A 78-year-old man with acute right lower abdominal pain and nausea was referred to our hospital. Computed tomography (CT) demonstrated hepatic portal venous gas and a thickened wall of the terminal ileum, and colonoscopy demonstrated ulcers and erosions of the ileocecal region. Histological examination of biopsy samples revealed basophilic crystals consistent with the component of calcium polystyrene sulfonate (CPS). This patient started taking CPS 2 months prior for chronic hyperkalemia. The symptoms resolved soon after ceasing CPS, and subsequent imaging studies confirmed the disappearance of the portal venous gas and ileocolitis.

Abstract
BACKGROUND Chronic enteropathy associated with SLCO2A1 gene (CEAS) is a hereditary disease caused by mutations in the SLCO2A1 gene and characterized by multiple small intestinal ulcers of nonspecific histology. SLCO2A1 is also a causal gene of primary hypertrophic osteoarthropathy (PHO). However, little is known about the clinical features of CEAS or PHO. METHODS Sixty-five Japanese patients recruited by a nationwide survey of CEAS during 2012-2016 were enrolled in this present study. We reviewed the clinical information of the genetically confirmed CEAS patients. RESULTS We identified recessive SLCO2A1 mutations at 11 sites in 46 patients. Among the 46 patients genetically confirmed as CEAS, 13 were men and 33 were women. The median age at disease onset was 16.5 years, and parental consanguinity was present in 13 patients (28%). Anemia was present in 45 patients (98%), while a single patient experienced gross hematochezia. All patients showed relatively low inflammatory markers in blood tests (median CRP 0.20 mg/dl). The most frequently involved gastrointestinal site was the ileum (98%), although no patient had mucosal injuries in the terminal ileum. Mild digital clubbing or periostosis was found in 13 patients (28%), with five male patients fulfilling the major diagnostic criteria of PHO. CONCLUSIONS The clinical features of CEAS are distinct from those of Crohn's disease. Genetic analysis of the SLCO2A1 gene is therefore recommended in patients clinically suspected of having CEAS.

Abstract
BACKGROUND Despite NUDT15 variants showing significant association with thiopurine-induced adverse events (AEs) in Asians, it remains unclear which variants of NUDT15 or whether additional genetic variants should be tested to predict AEs. To clarify the best pharmacogenetic test to be used clinically, we performed association studies of NUDT15 variants and haplotypes with AEs, genome-wide association study (GWAS) to discover additional variants, and ROC analysis to select the model to predict severe AEs. METHODS Overall, 2630 patients with inflammatory bowel disease (IBD) were enrolled and genotyped for NUDT15 codon 139; 1291 patients were treated with thiopurines. diplotypes were analyzed in 970 patients, and GWASs of AEs were performed with 1221 patients using population-optimized genotyping array and imputation. RESULTS We confirmed the association of NUDT15 p.Arg139Cys with leukopenia and alopecia (p = 2.20E-63, 1.32E-69, OR = 6.59, 12.1, respectively), and found a novel association with digestive symptoms (p = 6.39E-04, OR = 1.89). Time to leukopenia was significantly shorter, and when leukopenia was diagnosed, thiopurine doses were significantly lower in Arg/Cys and Cys/Cys than in Arg/Arg. In GWASs, no additional variants were found to be associated with thiopurine-induced AEs. Despite strong correlation of leukopenia frequency with estimated enzyme activities based on the diplotypes (r2 = 0.926, p = 0.0087), there were no significant differences in the AUCs of diplotypes from those of codon 139 to predict severe AEs (AUC = 0.916, 0.921, for acute severe leukopenia, AUC = 0.990, 0.991, for severe alopecia, respectively). CONCLUSIONS Genotyping of NUDT15 codon 139 was sufficient to predict acute severe leukopenia and alopecia in Japanese patients with IBD.

Abstract
BACKGROUND Patients with atopic dermatitis (AD) have superficial skin colonization by Staphylococcus aureus and an increased number of T helper type 2 (Th2) cells in their peripheral blood. Our previous study showed that josamycin, a macrolide antibiotic, had excellent bactericidal activity against S. aureus strains isolated from AD patients and simultaneously inhibited Th1 and Th2 cell development mediated by Langerhans cells. The purpose of the present study was to evaluate the effect of topical application of josamycin on AD-like skin lesions in NC/Nga mice. METHODS Josamycin (0.1%) was topically administered to NC/Nga mice with AD-like skin lesions induced by 2, 4, 6-trinitrochlorobenzene (TNCB). The therapeutic effects of josamycin were assessed by measurement of the skin severity scores, histological changes in the lesioned skin, serum levels of total IgE, and expression of interferon (IFN)-γ and interleukin (IL)-4 in lymph nodes and skin lesions. RESULTS Topical treatment with josamycin significantly suppressed the increase in the skin severity score in NC/Nga mice. This suppressive effect was equal to that of betamethasone, and was associated with a decrease in the density of cellular infiltration into the dermis, the mast cell count in the dermis and the serum IgE level. Furthermore, topical application of josamycin reduced the expression of IFN-γ and IL-4 in auricular lymph node cells and the skin lesions. CONCLUSION The present results show that topical application of josamycin inhibits the development of AD-like skin lesions in NC/Nga mice. This suggests that topical application of josamycin to AD lesions colonized by S. aureus would be beneficial for control of AD by acting on superficially located S. aureus and by inhibiting the development of Th1 and Th2 cells.This article is open to POST-PUBLICATION REVIEW.

Abstract
Small intestinal ulcers include mucosal damage caused by drugs, particularly nonsteroidal anti-inflammatory drugs [NSAIDs], infectious diseases, and idiopathic inflammatory bowel disease. Previously, a group of Japanese investigators reported an unusual and uncommon type of enteritis and referred to the condition as chronic nonspecific multiple ulcers of the small intestine [CNSU]. CNSU is characterised by chronic blood and protein loss through persistent small intestinal ulcers. Recently, four candidate mutations in the solute carrier organic anion transporter family, member 2A1 [SLCO2A1] gene, encoding a prostaglandin transporter, were identified by whole-exome sequencing in patients with CNSU. However, because the name 'CNSU' was somewhat ambiguous, the more appropriate nomenclature of 'chronic enteropathy associated with the SLCO2A1 gene' [CEAS] has been suggested. CEAS ulcers are characterised by multiple, circular or eccentric oblique, shallow lesions with discrete margins. The most frequently affected site of CEAS is the ileum, in contrast to 'cryptogenic multifocal ulcerous stenosing enteritis [CMUSE]', for which the most frequent site is the jejunum. Impaired prostaglandin utilisation is thought to cause the small intestinal mucosal damage observed in CEAS, CMUSE, and NSAID-induced enteropathy. This review article focuses on endoscopic and clinical features of genetically diagnosed CEAS, accumulated in a nationwide survey, and illustrates the observations in the format of an atlas.

Abstract
With the development of transplantation of hepatocytes into the spleen, interest has focused on the metabolic changes associated with hepatocyte proliferation. As these changes are important for drug metabolism in hepatocytes, we examined the expression and inducibility of the cytochrome P450 IIIA family within transplanted hepatocytes. Fetal hepatocytes were harvested at 20 days of gestation from spontaneously hypertensive rats (SHRs) and transplanted into recipient adult SHR spleens. Microscopic examination of the recipient spleens 4 and 10 wk after transplantation revealed masses of hepatocytes with cordlike structures in the red pulp. Proliferating hepatocytes were detected with a bromodeoxyuridine (BrdU) immunohistochemical stain. Immunochemical studies detected cytochromes (cytos) P450 p and P450 HLp in fetal hepatocytes before transplantation without prior induction. And although these cytos were not detected by 10 wk after transplantation, they were induced with dexamethasone. These results demonstrated that fetal hepatocytes can be transplanted successfully into recipient spleens and suggested that fetal hepatocytes grow in the spleen, similar to the adult hepatocyte response.

Abstract
Inflammatory bowel disease (IBD) results from a complex series of interactions between susceptibility genes, the environment, and the immune system. Recently, some studies provided strong evidence that the process of autophagy affects several aspects of mucosal immune responses. Autophagy is a cellular stress response that plays key roles in physiological processes, such as innate and adaptive immunity, adaptation to starvation, degradation of aberrant proteins or organelles, antimicrobial defense, and protein secretion. Dysfunctional autophagy is recognized as a contributing factor in many chronic inflammatory diseases, including IBD. Autophagy plays multiple roles in IBD pathogenesis by altering processes that include intracellular bacterial killing, antimicrobial peptide secretion by Paneth cells, goblet cell function, proinflammatory cytokine production by macrophages, antigen presentation by dendritic cells, and the endoplasmic reticulum stress response in enterocytes. Recent studies have identified susceptibility genes involved in autophagy, such as NOD2, ATG16L1, and IRGM, and active research is ongoing all over the world. The aim of this review is a systematic appraisal of the current literature to provide a better understanding of the role of autophagy in the pathogenesis of IBD. Understanding these mechanisms will bring about new strategies for the treatment and prevention of IBD.

Abstract
Despite the emergence of new biological therapies that aim for mucosal healing as a new therapeutic target, the importance of 5-ASA formulations in the standard treatment for inflammatory bowel diseases, particularly ulcerative colitis, remains unchanged. With a growing number of patients suffering from inflammatory bowel diseases in Japan, general physicians are also increasingly prescribing 5-ASA formulations. In order to obtain the maximum efficacy of 5-ASA formulations when treating inflammatory bowel diseases, it is essential that the dosage and administration are appropriate.

Abstract
778 Background: The CORRECT trial revealed the safety and efficacy of regorafenib (REG) for patients (pts) with colorectal cancer including Japanese. REG was approved in Japan in March 2013. However, there are few studies exploring the efficacy and safety of REG in a large number of patients, particularly in daily practice. Methods: We analyzed 173 pts who received REG from May 2013 in the multi-institutional retrospective study (HGCSG1401). This study was analyzed by CTCAE v4.0 for adverse events (AEs), RECIST v1.1 for response rate (RR)/disease control rate (DCR), and Kaplan-Meier method for progression free survival (PFS) and overall survival (OS). Results: Patients’ characteristics were as follows; male/female 98/75, median age 66 (range 29-87), ECOG PS (0/1/2/3) 58/96/18/1, KRAS Exon2 wild/mutant 98/74 (1 patient ; KRAS Exon2 status was not tested). The initial starting dose was 160 mg (n = 145, 83.8%), 120mg (n = 22, 12.7%), and 80mg (n = 6, 3.5%) respectively. Dose reductions were required in 73 pts (42.2%); 38 pts (22.0%) discontinued therapy due to AEs. The common ≥ grade 3 AEs ( ≥ 15%) were palmar-plantar erythrodysesthesia syndrome (n = 48; 27.7%), hypertension (n = 34; 19.7%), proteinuria (n = 24; 19.2%) and AST increased (n = 24; 13.9%). RR and disease control rate (DCR) were 1.3% and 29.6%, respectively. Median PFS and median survival time (MST) were 2.1 and 6.3 months. In an analysis on relationship between ECOG PS (PS 0-1 vs. PS 2-3) and efficacy, median PFS was 2.3 vs. 1.2 months (HR 3.598, p < 0.001), and MST was 7.0 vs. 2.1 months (HR 4.751, p < 0.001). Conclusions: The efficacy of REG in pts with PS 0–1 was similar to the previous report; however, REG was not effective in patients with PS 2–3. In adverse events, hypertension and liver dysfunction were expressed more frequently than previously reported. We will continue the analysis of the factors associated with liver dysfunction and prognostic/predictive factors.

Abstract
AIM To identify risk factors for post-polypectomy bleeding (PPB), focusing on antithrombotic agents.
METHODS This was a case-control study based on medical records at a single center. PPB was defined as bleeding that occurred 6 h to 10 d after colonoscopic polypectomy and required endoscopic hemostasis. As risk factors for PPB, patient-related factors including anticoagulants, antiplatelets and heparin bridge therapy as well as polyp- and procedure-related factors were evaluated. All colonoscopic hot polypectomies, endoscopic mucosal resections and endoscopic submucosal dissections performed between January 2011 and December 2014 were reviewed.
RESULTS PPB occurred in 29 (3.7%) of 788 polypectomies performed during the study period. Antiplatelet or anticoagulant agents were prescribed for 210 (26.6%) patients and were ceased before polypectomy except for aspirin and cilostazol in 19 cases. Bridging therapy using intravenous unfractionated heparin was adopted for 73 patients. The univariate analysis revealed that anticoagulants, heparin bridge, and anticoagulants plus heparin bridge were significantly associated with PPB (P < 0.0001) whereas antiplatelets and antiplatelets plus heparin were not. None of the other factors including age, gender, location, size, shape, number of resected polyps, prophylactic clipping and resection method were correlated with PPB. The multivariate analysis demonstrated that anticoagulants and anticoagulants plus heparin bridge therapy were significant risk factors for PPB (P < 0.0001). Of the 29 PPB cases, 4 required transfusions and none required surgery. A thromboembolic event occurred in a patient who took anticoagulant.
CONCLUSION Patients taking anticoagulants have an increased risk of PPB, even if the anticoagulants are interrupted before polypectomy. Heparin-bridge therapy might be responsible for the increased PPB in patients taking anticoagulants.

Abstract
Human cytomegalovirus (CMV) is a common cause of opportunistic infection leading to severe and fatal disease in immune-compromised individuals. In inflammatory bowel disease patients, particularly those with ulcerative colitis (UC), CMV is often reactivated because these patients are frequently treated with immunosuppressive agents. Many reports have described the relationship between CMV reactivation and UC exacerbation, however, a therapeutic strategy for CMV infection in UC patients has not been established. Area covered: This review highlights therapeutic strategies for UC patients with CMV infection. Recent findings have suggested a benefit from antiviral therapy in patients with histologically proven CMV colitis and/or a high colonic CMV load as determined by quantitative PCR. Expert commentary: To decide who requires antiviral therapies and when we start antiviral therapies, prospective studies of large numbers of UC patients with CMV infection are needed. However, we should know that the bottom-line therapy for UC patients with CMV infection is to optimally control mucosal inflammation.

Abstract
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.

Abstract
BACKGROUND Parameters reported in pathologic reviews have been failing to assess exactly the malignant potential of gastrointestinal cancers. We hypothesized that malignant potential could be defined by common latent variables (hypothesis I), but there are substantial differences in the associations between malignant potential and pathologic parameters according to the origin of gastrointestinal cancers (hypothesis II). We shed light on these issues by structural equation modeling. MATERIALS AND METHODS We conducted a cross-sectional survey of 217 esophageal, 192 gastric, and 175 colorectal cancer patients who consecutively underwent curative surgery for their pathologic stage I cancers at Keiyukai Sapporo Hospital. Latent variables identified by factor analysis and seven conventional pathologic parameters were introduced in the structural equation modeling analysis. RESULTS Because latent variables were disparate except for their number, 'three' in the examined gastrointestinal cancers, the first hypothesis was rejected. Because configural invariance across gastrointestinal cancers was not approved, the second hypothesis was verified. We could trace the three significant paths on the causal graph from latent variables to lymph node metastasis, which were mediated through depth, lymphatic invasion, and matrilysin expression in esophageal cancer, whereas only one significant path could be traced in both gastric and colorectal cancer. Two of the three latent variables were exogenous in esophageal cancer, whereas one factor was exogenous in the other gastrointestinal cancers. Cancer stemness promoted viability in esophageal cancer, but it was suppressed in others. CONCLUSION These results reflect the malignant potential of esophageal cancer is higher than that of the other gastrointestinal cancers. Such information might contribute to refining clinical treatments for gastrointestinal cancers.

Abstract
BACKGROUND The common disease-common variant hypothesis is insufficient to explain the complexities of Crohn's disease (CD) genetics; therefore, rare variants are expected to be important in the disease. We explored rare variants associated with susceptibility to CD in Japanese individuals by personal genomic analysis. METHODS Two-step analyses were performed. The first step was a trio analysis with whole-exome sequence (WES) analysis and the second was a follow-up case-control association study. The WES analysis pipeline comprised Burrows-Wheeler Aligner, Picard, Genome Analysis Toolkit, and SAMTOOLS. Single nucleotide variants (SNVs)/indels were annotated and filtered by using programs implemented in ANNOVAR in combination with identity-by-descent (IBD), subsequently were subjected to the linkage based, and de novo based strategies. Finally, we conducted an association study that included 176 unrelated subjects with CD and 358 healthy control subjects. RESULTS In family members, 234,067-297,523 SNVs/indels were detected and they were educed to 106-146 by annotation based filtering. Fifty-four CD variants common to both individuals of the affected sib pair were identified. The linkage based strategy detected five candidate variants whereas the de novo based strategy identified no variants. Consequently, five candidates were analyzed in the case-control association study. CD showed a significant association with one variant in exon 4 of IL23R, G149R [rs76418789, P = 3.9E-5, odds ratio (OR) 0.21, 95% confidence interval (CI) 0.09-0.47 for the dominant model (AA + AG versus GG), and P = 7.3E-5, OR 0.21, 95% CI 0.10-0.48 for AG versus GG, and P = 7.2E-5, OR 0.23, 95% CI 0.10-0.50 for the allele model]. CONCLUSIONS The present study, using personal genomics analysis of a small CD pedigree, is the first to show that the low-frequency non-synonymous variant of IL23R, rs76418789, protects against CD development in Japanese subjects.

Abstract
The role of mesenchymal stem cells (MSCs) in tumorigenesis remains controversial. Therefore, our goal was to determine whether exogenous MSCs possess intrinsic antineoplastic or proneoplastic properties in azoxymethane (AOM)-induced carcinogenesis. Three in vivo models were studied: an AOM/dextran sulfate sodium colitis-associated carcinoma model, an aberrant crypt foci model, and a model to assess the acute apoptotic response of a genotoxic carcinogen (AARGC). We also performed in vitro coculture experiments. As a result, we found that MSCs partially canceled AOM-induced tumor initiation but not tumor promotion. Moreover, MSCs inhibited the AARGC in colonic epithelial cells because of the removal of O(6)-methylguanine (O(6) MeG) adducts through O(6) MeG-DNA methyltransferase activation. Furthermore, MSCs broadly affected the cell-cycle machinery, potentially leading to G1 arrest in vivo. Coculture of IEC-6 rat intestinal cells with MSCs not only arrested the cell cycle at the G1 phase, but also induced apoptosis. The anti-carcinogenetic properties of MSCs in vitro required transforming growth factor (TGF)-β signaling because such properties were completely abrogated by absorption of TGF-β under indirect coculture conditions. MSCs inhibited AOM-induced tumor initiation by preventing the initiating cells from sustaining DNA insults and subsequently inducing G1 arrest in the initiated cells that escaped from the AARGC. Furthermore, tumor initiation perturbed by MSCs might potentially dysregulate WNT and TGF-β-Smad signaling pathways in subsequent tumorigenesis. Obtaining a better understanding of MSC functions in colon carcinogenesis is essential before commencing the broader clinical application of promising MSC-based therapies for cancer-prone patients with inflammatory bowel disease.

Abstract
BACKGROUND Recent studies have suggested that narrow band imaging (NBI) is useful for detecting superficial pharyngeal cancer. Nevertheless, pharyngeal observation is not a routine practice during upper gastrointestinal (GI) endoscopy. Two aims of this study were to evaluate the feasibility of pharyngeal observation during upper GI endoscopy and to determine the prevalence of pharyngeal cancer in asymptomatic high-risk patients. METHODS Fifty-year-old or older asymptomatic males with smoking and drinking habits were prospectively recruited as a pharyngeal cancer high-risk group. A total of 224 high-risk patients underwent pharyngeal observation using NBI before conventional upper GI endoscopy. The feasibility of pharyngeal examination without sedation was assessed by a questionnaire for the first 60 participants. RESULTS The median time for pharyngeal observation was 1.7 min. The questionnaire demonstrated 88% of participants thought the pharyngeal examination acceptable. The NBI examination identified 5 superficial pharyngeal cancers (2 Tis and 3 T1) in 224 high-risk patients; the prevalence of pharyngeal cancer in this group was 2.2%. Three of the 5 patients had a concurrent or past history of esophageal squamous cell carcinoma (ESCC). CONCLUSIONS Pharyngeal observation using NBI during upper GI endoscopy is well tolerated and recommended for all high-risk patients, particularly those with a history of ESCC. Basel.

Abstract
OBJECTIVES To evaluate tooth position after six and 9 months of orthodontics with conventional brackets on one side of the dentition and ligature-less brackets on the other. SETTING AND SAMPLE POPULATION Orthodontic Division, Vienna Medical University. Twenty patients aged 22.5 ± 5.7 years, symmetrical malocclusion and arch form, no premolar extraction. MATERIAL AND METHODS Prospective split-mouth study, 0.022-inch SmartClip self-ligating brackets assigned randomly to the left or right dentition, conventional 0.018-inch brackets on the other side. 52 dental landmarks, digitized on plaster casts, represented dental arches at baseline (t0), 6 months and 9 months (t1, t2). During t0-t1, we used 0.016 and 0.014 x 0.025 inch superelastic wires, during t1-t2 connected reverse-curve hemiarch wires: 0.017 x 0.025 inch ß-titanium on the ligature-less side, and 0.016 x 0.022 inch Elgiloy multiloop wires on conventional brackets. Morphometric analyses were used to assess differences in dental arch shapes. RESULTS Neither initial alignment nor the reverse-curve phase showed statistically significant differences between ligature-less and conventional brackets in moving teeth. CONCLUSION Morphometric shape analyses corroborated current evidence that self-ligating brackets were no more effective than conventional brackets with steel ligatures after 6-month initial alignment. From months 6-9 treatment with ß-titanium reverse-curve wires on 0.022-inch ligature-less brackets resulted in similar tooth positions as accomplished by Elgiloy multiloop wires on 0.018-inch steel-ligature-tied brackets.

Abstract
BACKGROUND Although mounting evidence implicates mesenchymal stem cells (MSCs) in intestinal tissue repair, controversy remains regarding the engraftment, proliferation, and differentiation for repopulating MSCs in recipient tissues. Therefore, we investigated the paracrine and/or endocrine role of MSCs in experimental colitis. METHODS We analyzed the therapeutic effects of MSC-conditioned medium (MSC-CM) on dextran sulfate sodium (DSS)- or 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis. We investigated the effects of MSC-CM on the epithelial cell viability, mobility, cell cycle, and cytokine production in ex vivo lamina propria/mesenteric lymphocytes, a macrophage cell line, and the mixed lymphocyte reaction. An optimal regimen against colitis was explored. The contents of MSC-CM were analyzed using a WNT signaling pathway polymerase chain reaction array, an inflammatory cytokines antibody array, and liquid chromatography-tandem mass spectrometry analysis. RESULTS Independent of the systemic administration route, MSC-CM concentrates were effective for the inductive phase of TNBS-induced colitis and for the recovery phase of DSS-induced colitis. Hypoxia appeared to be one of the optimal preconditioning factors assessed by cell motility and viability through activating the PI3K-Akt pathway in rat small intestine epithelial cells, IEC-6. Thus, Hypoxia had profound effects on the contents of MSC-CM, which comprised pleiotropic gut trophic factors involved in each wound healing process, including the anti-inflammatory, proliferative, and tissue remodeling phases. CONCLUSIONS Identification and optimization of potential gut trophic factors in MSC-CM is urgently needed to form the basis for new drug discovery and for optimizing cell-based therapies for inflammatory bowel disease.
