Abstract
BACKGROUND AND AIMS Endoscopic placement of self-expandable metal stents (SEMSs) for malignant distal biliary obstruction (MDBO) may be accompanied by several types of adverse events. The present study analyzed the adverse events occurring after SEMS placement for MDBO. METHODS The present study retrospectively investigated the incidence and types of adverse events in patients who underwent SEMS placement for MDBO between April 2018 and March 2021 at 26 hospitals. Risk factors for acute pancreatitis, cholecystitis, and recurrent biliary obstruction (RBO) were evaluated by univariate and multivariate analyses. RESULTS Of the 1425 patients implanted with SEMSs for MDBO, 228 (16.0%) and 393 (27.6%) experienced early adverse events and RBO, respectively. Pancreatic duct without tumor involvement (P = .023), intact papilla (P = .025), and SEMS placement across the papilla (P = .037) were independent risk factors for acute pancreatitis. Tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis (P < .001). Use of fully and partially covered SEMSs was an independent risk factor for food impaction and/or sludge. Use of fully covered SEMSs was an independent risk factor for stent migration. Use of uncovered SEMSs and laser-cut SEMSs was an independent risk factor for tumor ingrowth. CONCLUSIONS Pancreatic duct without tumor involvement, intact papilla, and SEMS placement across the papilla were independent risk factors for acute pancreatitis, and tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis. The risk factors for food impaction and/or sludge, stent migration, and tumor ingrowth differed among types of SEMSs.

Abstract
BACKGROUND Endogenous bacterial endophthalmitis is caused by a breach of the blood-ocular barrier by pathogens originating from distant infective foci. Here, we report a case of endogenous endophthalmitis due to cholangitis complicated by common bile duct stones, which is a rare source of infection. CASE REPORT A 73-year-old man with type II diabetes mellitus underwent endoscopic choledocholithotripsy 20 years ago and laparoscopic cholecystectomy 18 years ago. He had choledocholith-related cholangitis 6, 5, and 1 years previously and 4 times in the last year and underwent endoscopic choledocholithotripsy each time. Three days after the last surgery, the patient developed right endogenous endophthalmitis and vitrectomy was performed. Four months later, the patient relapsed with cholangitis and required surgery for recurrent endophthalmitis. Roux-en-Y choledochojejunostomy was performed with curative intent, and the patient was followed up for 5 years without recurrence of choledocholith, cholangitis, or endophthalmitis. CONCLUSIONS The recommended treatment strategy for patients diagnosed with common bile duct stones or choledocholithiasis is stone extraction. Endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic intervention is a widely accepted procedure. However, in cases of recurrent choledocholithiasis, the rate of recurrence increases and the interval between ERCP becomes shorter in proportion to the number of recurrences. In such intractable cases requiring numerous sessions of endoscopic stone removal, bypass Roux-en-Y choledochojejunostomy should be performed to prevent possible rare complications such as endogenous bacterial endophthalmitis.

Abstract
Pyloric gland adenoma (PGA) in the duodenum is a rare gastric phenotype duodenal neoplasm. Although heterotopic gastric mucosa in the duodenum has been recognized as a benign lesion, it is a potential precursor of PGA and gastric phenotype adenocarcinoma. Herein, we present a case follow-up of endoscopic and histological changes in the PGA in the duodenum from low-grade to high-grade dysplasia. PGA was considered to arise from the heterotopic gastric mucosa, because the heterotopic gastric mucosa was observed in the initial examination. It is difficult to distinguish heterotopic gastric mucosa from PGAs, both endoscopically and histologically. This increase in size may be useful for their differentiation. Therefore, endoscopists should not underestimate the growth of the heterotopic gastric mucosa compared to that in the previous examination.

Abstract
BACKGROUND There is no consensus on the necessity of endoscopic sphincterotomy (ES) to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) after endoscopic stenting in patients with malignant biliary obstruction. We investigated the incidence of PEP after endoscopic biliary stenting for malignant biliary obstruction with or without ES in a multicenter prospective cohort study. METHODS We enrolled 807 patients who underwent endoscopic biliary stenting for malignant biliary obstruction with a native papilla at 36 hospitals between April 2017 and March 2018. The incidence of PEP in patients with or without ES was compared for subgroups based on stent type, placement method, and patient background. Univariate and multivariate analysis was performed to investigate the incidence of PEP in all stenting patients. RESULTS Plastic and metal stents (MS) were inserted in 598 and 209 patients, respectively. The incidence of PEP in patients with or without ES was 7.9% and 7.4%, respectively among all stenting patients. The incidences of PEP with or without ES in plastic stent insertion patients, patients with MS insertion, stent insertions across the papilla, stent insertions across the papilla in patients without main pancreatic duct obstruction, and fully covered MS insertions across the papilla were compared. There was no overall significant difference in the incidence of PEP between those with or without ES. Multivariate logistic regression analysis for the incidence of PEP in all stenting patients revealed obstruction of the main pancreatic duct at the pancreatic head and epinephrine spraying on the papilla were significant factors; there was no significant difference in the incidence of PEP between patients with or without ES. CONCLUSION Endoscopic sphincterotomy may not contribute to the prevention of PEP after endoscopic biliary stenting for malignant biliary obstruction, even in cases of insertion with a fully covered MS across the papilla.

Abstract
Although dexmedetomidine (DEX) is a widely used analgesic and sedative agent for endoscopic procedures, cardiovascular complications, such as bradycardia and hypotension, are frequently experienced. We herein report the first case of asystole-induced bradycardia due to DEX during endoscopic submucosal dissection (ESD). An 81-year-old man without cardiovascular diseases was referred for gastric carcinoma. ESD was started after administering a loading dose of DEX followed by a continuous maintenance infusion of DEX. The patient's heart rate gradually decreased, and then cardiac arrest occurred. DEX has a risk of cardiac arrest, so bradycardia should not be underestimated during sedation with DEX.

Abstract
BACKGROUND AND AIMS Endoscopic resection of nonampullary duodenal adenoma is often challenging, and its technique has not yet been standardized. To overcome the practical difficulty of conventional endoscopic mucosal resection, underwater endoscopic mucosal resection (UEMR) was recently developed; therefore, we investigated the effectiveness and safety of UEMR for nonampullary duodenal adenoma. METHODS A multicenter, prospective cohort study was conducted at 21 institutions in Japan. We enrolled patients with no more than 2 nonampullary duodenal adenomas ≤20 mm in size, who were planned to undergo UEMR. After UEMR, follow-up endoscopies were scheduled at 2 and 12 months after the procedure, and biopsy specimens were taken from the post-UEMR scars. The primary endpoint was the proportion of patients with histologically proven nonrecurrence at follow-up endoscopy and biopsy. RESULTS A total of 155 patients with 166 lesions underwent UEMR. One patient with a non-neoplastic lesion in the resected specimen and 10 patients with 10 lesions who were lost to follow-up were excluded. Finally, 144 patients with 155 lesions who received all follow-up endoscopies were analyzed for the primary endpoint. The proportion of patients with proven nonrecurrence was 97.2% (n = 140 of 144; 95% confidence interval, 92.8%-99.1%) which exceeded the predefined threshold value (92%). Two cases of delayed bleeding (1.2%) occurred and they were successfully managed by clips. All recurrences were successfully treated by additional endoscopic treatment. CONCLUSIONS This multicenter, prospective cohort study demonstrated effectiveness and safety of UEMR for nonampullary duodenal adenomas ≤20 mm in size.

Abstract
The occurrence of cryptic species within a threatened taxon is rare, but where they do occur, understanding species boundaries is essential for planning an effective conservation strategy. The short-tailed albatross Phoebastria albatrus is a Vulnerable seabird that mainly breeds on Torishima and the Senkaku Islands in the western North Pacific. Although it has been tacitly regarded as a single management unit with 2 breeding sites, the species is known to comprise 2 genetically separated populations (Senkaku-type and Torishima-type). However, morphological examination of birds from both populations has not been conducted owing to the difficulty in accessing the Senkaku Islands. In this study, we examined the morphological differences between immigrants from the Senkaku Islands to Torishima (Senkaku-type) and native birds on Torishima (Torishima-type) and found significant differences in morphological characteristics between the 2 bird types. In general, Torishima-type birds were larger than Senkaku-type birds, whereas Senkaku-type birds had relatively longer beaks. Based on the morphological differences found in this study as well as genetic and ecological differences revealed in previous studies, we believe that Senkaku- and Torishima-type birds should be classified as different cryptic species. To the best of our knowledge, this is the first case of cryptic species being identified in a threatened avian species.

Abstract
Mallory-Weiss tears (MWT) are occasionally encountered during endoscopic procedures. Esophageal endoscopic submucosal dissection (ESD) is widely performed under general anesthesia to avoid unexpected body movements. We present the case of a 68-year-old woman with squamous cell carcinoma. Although ESD was performed under general anesthesia, a gastric perforation at the MWT caused by gastric inflation was observed after the procedure. The perforation was closed endoscopically, and she was discharged without any sequelae. Although general anesthesia is useful for esophageal ESD, it should be noted that it can cause MWT, and in rare cases, gastric perforation, due to gastric inflation during the procedure.

Abstract
Abstract
Background
The visually guided laser balloon ablation is a balloon-based catheter ablation technology used for atrial fibrillation (AF) ablation in recent years. This balloon catheter consists of a compliant balloon that has the capability of real-time endoscopic visualization of the targeted pulmonary vein (PV). The sizeable balloon is usually inflated to obtain optimal PV occlusion. The isolation area after laser balloon (LB) ablation was reported to be smaller than that after cryoballoon ablation. However, when LB is inflated with its maximum pressure, it can visualize wide-area PV antrum. Thereby, we suspected that larger-size LB can create wider isolation area.
Purpose
The aim of this study is to quantitatively evaluate the isolation area after LB ablation at the size larger than appropriate size for ablation in the pulmonary vein carina region.
Methods
We assessed 66 patients with AF who underwent LB ablation at the larger inflation size in our hospital during the period from July 2018 to July 2019. After LB ablation, we created voltage maps with a circular mapping catheter and calculated isolation areas with CARTO system.
Results
Figure shows a larger LB with its maximum pressure. PV antrum isolation was extended to the posterior wall in all patients. The left- and right-sided pulmonary vein antrum isolation area were 15.1±3.9 and 19.4±4.3 cm2, respectively.
Conclusion
LB at the larger inflation size with its maximum pressure can isolate wider-area circumferential PV antrum than previously reported. This method may be a new way of pulmonary vein antrum isolation.

Abstract
Plexiform neurofibroma is mainly associated with neurofibromatosis type 1 and is seldom observed in the liver. Its occurrence in the liver without neurofibromatosis type 1 is even rarer. We report an extremely rare case of plexiform neurofibroma of the liver diagnosed by laparoscopic biopsy in a patient without neurofibromatosis type 1. The patient was a 35-year-old man who had neither clinical signs nor any family history of neurofibromatosis type 1. Abdominal ultrasonography, as part of a health screening, had detected a hepatic tumor. Subsequent contrast ultrasonography, computed tomography, and magnetic resonance imaging showed the tumor extending from the retroperitoneal space around the aorta to the hepatic hilum and distal portal branches in the right hepatic lobe, gallbladder, and left hepatic lobe. 18F-fluorodeoxyglucose positron emission tomography showed no abnormal accumulation. Histopathological examination of the tumor obtained laparoscopically led to a diagnosis of plexiform neurofibroma. Because the patient was asymptomatic with no features of malignancy, he was only monitored and managed. At follow-up 10 years later, computed tomography showed a decrease in tumor size. It is important to recognize that, while rare, plexiform neurofibroma can occur without neurofibromatosis type 1. We recommend follow-up instead of unreasonable surgery in such cases.

Abstract
A 42-year-old man, after remission of MALT lymphoma of the small intestine, was repeatedly hospitalized because of abdominal pain and severe dehydration caused by frequent vomiting and watery diarrhea. His symptoms would improve quickly every time when he was fasted and inserted a nasogastric tube. We were unable to find abnormalities on endoscopic examination and computed tomography. He was suspected to have gastrinoma because of active bleeding from a duodenal ulcer. High-level serum gastrin, endoscopic ultrasound, somatostatin receptor scintigraphy, and selective arterial calcium injection test were done. He was diagnosed with pancreatic gastrinoma in the pancreatic head by endoscopic ultrasound fine needle aspiration and subsequently underwent pancreatoduodenectomy. Histopathologic findings showed a 3-mm neuroendocrine tumor located in the duodenal submucosal layer. The presence of metastasis was confirmed in one of the peripancreatic lymph nodes. The pancreatic gastrinoma in the pancreatic head that we initially diagnosed was a lymph node metastasis behind the pancreas. Because additional resection was performed on the duodenum, we were able obtain a diagnosis of duodenal gastrinoma.

Abstract
Inwardly rectifying potassium (Kir) channels play key roles in functions, including maintaining the resting membrane potential and regulating the action potential duration in excitable cells. Using in situ whole-cell recordings, we investigated Kir currents in mouse fungiform taste bud cells (TBCs) and immunologically identified the cell types (type I-III) expressing these currents. We demonstrated that Kir currents occur in a cell-type-independent manner. The activation potentials we measured were -80 to -90 mV, and the magnitude of the currents increased as the membrane potentials decreased, irrespective of the cell types. The maximum current densities at -120 mV showed no significant differences among cell types (p>0.05, one-way ANOVA). The density of Kir currents was not correlated with the density of either transient inward currents or outwardly rectifying currents, although there was significant correlation between transient inward and outwardly rectifying current densities (p<0.05, test for no correlation). RT-PCR studies employing total RNA extracted from peeled lingual epithelia detected mRNAs for Kir1, Kir2, Kir4, Kir6, and Kir7 families. These findings indicate that TBCs express several types of Kir channels functionally, which may contribute to regulation of the resting membrane potential and signal transduction of taste.

Abstract
BACKGROUND Management of anticoagulants for patients undergoing polypectomy is still controversial. Cold snare polypectomy (CSP) is reported to cause less bleeding than hot snare polypectomy (HSP). OBJECTIVE To compare outcomes between continuous administration of anticoagulants (CA) with CSP (CA+CSP) and periprocedural heparin bridging (HB) with HSP (HB+HSP) for subcentimeter colorectal polyps. DESIGN Multicenter, parallel, noninferiority randomized controlled trial. (University Hospital Medical Information Network Clinical Trials Registry: UMIN000019355). SETTING 30 Japanese institutions. PATIENTS Patients receiving anticoagulant therapy (warfarin or direct oral anticoagulants) who had at least 1 nonpedunculated subcentimeter colorectal polyp. INTERVENTION Patients were randomly assigned to undergo HB+HSP or CA+CSP and followed up 28 days after polypectomy. MEASUREMENTS The primary end point was incidence of polypectomy-related major bleeding (based on the incidence of poorly controlled intraprocedural bleeding or postpolypectomy bleeding requiring endoscopic hemostasis). The prespecified inferiority margin was -5% (CA+CSP vs. HB+HSP). RESULTS A total of 184 patients were enrolled: 90 in the HB+HSP group, 92 in the CA+CSP group, and 2 who declined to participate after enrollment. The incidence of polypectomy-related major bleeding in the HB+HSP and CA+CSP groups was 12.0% (95% CI, 5.0% to 19.1%) and 4.7% (CI, 0.2% to 9.2%), respectively. The intergroup difference for the primary end point was +7.3% (CI, -1.0% to 15.7%), with a 0.4% lower limit of 2-sided 90% CI, demonstrating the noninferiority of CA+CSP. The mean procedure time for each polyp and the hospitalization period were longer in the HB+HSP than in the CA+CSP group. LIMITATION An open-label trial assessing 2 factors (anticoagulation approach and polypectomy procedure type) simultaneously. CONCLUSION Patients having CA+CSP for subcentimeter colorectal polyps who were receiving oral anticoagulants did not have an increased incidence of polypectomy-related major bleeding, and procedure time and hospitalization were shorter than in those having HB+HSP.

Abstract
An 82-year-old female underwent contrast computed tomography (CT) that revealed multiple ring-like enhanced masses in the pancreatic tail. Additionally, the inside of the masses showed enhancement on contrast endoscopic ultrasound (EUS). She was diagnosed with a pancreatic neuroendocrine tumor on histopathological examination after EUS-guided fine-needle aspiration, and distal pancreatectomy and splenectomy were performed. In the resected specimen, toward the tumor center, tumor cells with lipid droplets and fibrosis were remarkably observed. These rare histopathological features well reflected the image findings of contrast CT and contrast EUS.

Abstract
Recipients of organ transplants are immunosuppressed and at high risk of oral infection. Oral diseases are often neglected compared with infections of other organs that typically confer higher morbidity. However, severe local symptoms hinder oral intake, decrease quality of life, and are sometimes lethal. Here we describe a case of a 57-year-old woman who developed recurrent aphthous stomatitis after kidney transplantation; the cause of the infection was complex and included cytomegalovirus, herpes simplex virus, and Candida species. Since misdiagnosis of oral diseases impairs patient quality of life and increases morbidity, clinicians should be aware of possible etiologies of oral infections in renal transplant recipients.

Abstract
AIMS The aim of this study was to report the long-term results of rotational acetabular osteotomy (RAO) for symptomatic hip dysplasia in patients aged younger than 21 years at the time of surgery. PATIENTS AND METHODS We evaluated 31 patients (37 hips) aged younger than 21 years at the time of surgery retrospectively. There were 29 female and two male patients. Their mean age at the time of surgery was 17.4 years (12 to 21). The mean follow-up was 17.9 years (7 to 30). The RAO was combined with a varus or valgus femoral osteotomy or a greater trochanteric displacement in eight hips, as instability or congruence of the hip could not be corrected adequately using RAO alone. RESULTS The mean Merle d'Aubigné clinical score improved significantly from 15.4 to 17.2 (p < 0.0001). The mean centre-edge (CE) angle improved from -2.6° to 26°, the mean acetabular roof angle improved from 3.0° to 5.2°, and the mean head lateralization index improved from 0.68 to 0.62. Progression of radiological osteoarthritis (OA) was seen in seven hips, but no patient underwent total hip arthroplasty. CONCLUSION RAO is an effective form of correction for a severely dysplastic hip in adolescent and young adult patients. Cite this article: Bone Joint J 2019;101-B:390-395.

Abstract
BACKGROUND High-resolution esophageal manometry (HREM) has become a leading tool in the assessment of esophageal motor disorders, replacing conventional manometry. However, there is limited data about the contribution of HREM as compared with conventional manometry to the assessment of esophageal motor disorders in patients with non-cardiac chest pain (NCCP). The aim of the study was to compare the distribution of esophageal motor disorders in patients with NCCP using HREM as compared with conventional manometry and to determine if HREM improved diagnosis of these disorders. METHODS In this study, we included 300 consecutive patients with NCCP who underwent either HREM or conventional manometry over a period of 10 years. A total of 150 patients had conventional manometry and the other 150 patients HREM. The Chicago 3.0 classification and the Castell and Spechler classification were used to determine the esophageal motor disorder of NCCP patients undergoing HREM and conventional manometry, respectively. KEY RESULTS In both HREM and the conventional manometry groups, normal esophageal motility was the most frequent finding (47% and 36%; respectively, P = .054). Hypotensive lower esophageal sphincter was the most common motility disorder identified by conventional manometry (27.3%), while ineffective esophageal motility was the most common esophageal motor disorder identified by HREM (25.3%). CONCLUSIONS & INFERENCES There is a discrepancy in the type of esophageal motor disorders identified by HREM as compared with conventional manometry in NCCP patients. Hypotensive motility disorders are the most commonly diagnosed by both manometric techniques.

Abstract
Aims Our aim was to evaluate the radiographic characteristics of patients undergoing total hip arthroplasty (THA) for the potential of posterior bony impingement using CT simulations. Patients and Methods Virtual CT data from 112 patients who underwent THA were analysed. There were 40 men and 72 women. Their mean age was 59.1 years (41 to 76). Associations between radiographic characteristics and posterior bony impingement and the range of external rotation of the hip were evaluated. In addition, we investigated the effects of pelvic tilt and the neck/shaft angle and femoral offset on posterior bony impingement. Results The range of external rotation and the ischiofemoral length were significantly lower, while femoral anteversion, the ischial ratio, and ischial angle were significantly higher in patients with posterior bony impingement compared with those who had implant impingement (p < 0.05). The range of external rotation positively correlated with ischiofemoral length (r = 0.49, p < 0.05), and negatively correlated with ischial length (r = -0.49, p < 0.05), ischial ratio (r =- 0.49, p < 0.05) and ischial angle (r = -0.55, p < 0.05). The range of external rotation was lower in patients with posterior pelvic tilt (p < 0.05) and in those with a high offset femoral component (p < 0.05) due to posterior bony impingement. Conclusion Posterior bony impingement after THA is more likely in patients with a wider ischium and a narrow ischiofemoral space. A high femoral offset and posterior pelvic tilt are also risk factors for this type of impingement. Cite this article: Bone Joint J 2017;99-B:1140–6.

Abstract
INTRODUCTION This study describes our clinical experience of late conversion from antimetabolites with standard exposure calcineurin inhibitors (CNIs) to everolimus with CNI minimization in stable kidney transplant recipients with good graft function. PATIENTS AND METHODS A 1-year retrospective pilot study of 26 kidney recipients converted from antimetabolites with standard exposure CNIs to everolimus with CNI minimization was performed. The recipients enrolled in this study had normal or slightly impaired renal function defined as a serum creatinine value <2.0 mg/dL, and normal or slightly increased albuminuria defined as a urinary albumin excretion rate <100 mg/g creatinine. RESULTS The median time from transplant to conversion was 39.5 months posttransplant (range, 3-275). Treatment with everolimus was stopped owing to adverse events in 11 patients (42.3%). In the analysis of the patients in whom everolimus was maintained, the mean estimated glomerular filtration rate (eGFR) significantly increased from 50.7 ± 11.9 mL/min/1.73 m(2) at baseline to 53.6 ± 13.9 mL/min/1.73 m(2) at 1 year after conversion. In the patients in whom everolimus was stopped during the observation period, there was no difference in eGFR between baseline and 1 year after conversion. CONCLUSIONS This study demonstrated that, among the patients converted to everolimus at a late stage, there was no deterioration in renal function whether everolimus was maintained or stopped within 1 year after conversion.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with 25-gauge needles yields small volume samples that are mainly processed for cytology. Using 25-gauge needles with a core trap may overcome this limitation. This trial compared 25-gauge needles with and without a core trap in terms of their ability to obtain histologic samples from solid pancreatic masses. PATIENTS AND METHODS Consecutive patients with solid pancreatic masses who presented to eight Japanese referral centers for EUS-FNA in April - September 2013 were randomized to undergo sampling with a 25-gauge needle with a core trap (ProCore) or a standard 25-gauge needle. Tissue samples were fixed in formalin and processed for histologic evaluation. For the purpose of this study only samples obtained with the first needle pass were used for comparison of: (i) accuracy for the diagnosis of malignancy, (ii) rate of samples with preserved tissue architecture adequate for histologic evaluation, and (iii) sample cellularity. RESULTS A total of 214 patients were enrolled. Compared to the first pass with a standard needle (n = 108), the first pass with the ProCore needle (n = 106) provided samples that were more often adequate for histologic evaluation (81.1 % vs. 69.4 %; P = 0.048) and had superior cellularity (rich/moderate/poor, 36 %/27 %/37 % vs. 19 %/26 %/55 %; P = 0.003). There were no significant differences between the two needles in sensitivity (75.6 % vs. 69.0 %, P = 0.337) and accuracy (79.2 % vs. 75.9 %, P = 0.561) for the diagnosis of malignancy. CONCLUSIONS In patients with solid pancreatic masses, a 25-gauge EUS-FNA needle with a core trap provides histologic samples of better quality than a standard 25-gauge needle. There was no difference in accuracy for the diagnosis of malignancy between the needles. CLINICAL TRIAL NUMBER UMIN000010021.

Abstract
BACKGROUND Interleukin-22 (IL-22) has been recently highlighted owing to its biological significance in the modulation of tissue responses during inflammation. However, the role of IL-22 in carcinogenesis has remained unclear. Here, we investigated the pathophysiological significance of IL-22 expression in gastric cancer tissues and examined the mechanism by which IL-22 promotes gastric cancer cell invasion. METHODS Human gastric cancer specimens were analysed by immunohistochemistry for expression of IL-22 and IL-22 receptor 1 (IL-22R1). The effects of IL-22-induced STAT3 and ERK signalling on invasive ability of gastric cancer cells were examined using a small-interfering RNA system and specific inhibitors. AGS cells were co-cultured with cancer-associated fibroblasts (CAFs) from human gastric cancer tissues and assessed by invasion assay. RESULTS Interleukin-22 and its receptor were expressed in α-smooth muscle actin-positive stromal cells and tumour cells at the invasive front of gastric cancer tissues, respectively. The expression of IL-22 and IL-22R1 was significantly related to lymphatic invasion. Interleukin-22 treatment promoted the invasive ability of gastric cancer cells through STAT3 and ERK activation. The invasive ability of gastric cancer cells was significantly enhanced by co-culture with IL-22-expressing CAFs. CONCLUSIONS Interleukin-22 produced by CAFs promotes gastric cancer cell invasion via STAT3 and ERK signalling.

Abstract
In Japan, osteoarthritis (OA) of the hip secondary to acetabular dysplasia is very common, and there are few data concerning the pathogeneses and incidence of femoroacetabular impingement (FAI). We have attempted to clarify the radiological prevalence of painful FAI in a cohort of Japanese patients and to investigate the radiological findings. We identified 176 symptomatic patients (202 hips) with Tönnis grade 0 or 1 osteoarthritis, whom we prospectively studied between August 2011 and July 2012. There were 61 men (65 hips) and 115 women (137 hips) with a mean age of 51.8 years (11 to 83). Radiological analyses included the α-angle, centre–edge angle, cross-over sign, pistol grip deformity and femoral head neck ratio. Of the 202 hips, 79 (39.1%) had acetabular dysplasia, while 80 hips (39.6%) had no known aetiology. We found evidence of FAI in 60 hips (29.7%). Radiological FAI findings associated with cam deformity were the most common. There was a significant relationship between the pistol grip deformity and both the α-angle (p < 0.001) and femoral head–neck ratio (p = 0.024). Radiological evidence of symptomatic FAI was not uncommon in these Japanese patients. Cite this article: Bone Joint J 2013;96-B:172–6.

Abstract
A 79-year-old woman with a history of pyothorax was admitted with a 4-day history of abdominal distension. Physical examination revealed marked abdominal distention, absent bowel sounds, and a vesicular rash over the left Th8-10 dermatome. Abdominal radiography showed gaseous distension of the colon and ileum. Colonoscopy excluded any obstructive process of the colon. Laboratory findings yielded positive results for serum IgM and IgG against the varicella zoster virus (VZV) . Paralytic ileus associated with the VZV was therefore diagnosed. The ileus improved after conservative treatment with intravenous acyclovir. Although shingles is frequently encountered, it is a rare cause of paralytic ileus. In the future, the VZV should be considered as one of the causes of paralytic ileus, and complete resolution can be achieved with conservative management.

Abstract
Influence of vitamin A on the beef quality of the Tajima strain of Japanese Black cattle was studied. Marbling scores were correlated with serum vitamin A concentrations just before slaughter (r = -0.38). The mean marbling score of the low vitamin A group that were not supplemented with vitamin A after 15 months of age was significantly higher than that of the group supplemented with high vitamin A. However, there was no significant difference in the marbling scores between the group that were not given vitamin A after 23 months of age and the high vitamin A supplemented group. These results suggest that vitamin A supplementation affects carcass marbling only if given before 23 months of age, in these cattle.

Abstract
A 40's woman was hospitalized with cervical lymph node enlargement. Laboratory examinations showed elevated serum bile duct enzymes and the presence of anti-mitochondrial antibody. Abdominal ultrasonography and computed tomography showed enlargement of not only perihepatic lymph nodes, but also axillary and cervical lymph nodes. FDG-PET showed intense uptake concordant with these lymph nodes. We performed endoscopic ultrasonographic fine-needle aspiration biopsy of a perihepatic lymph node, but detected no malignant cells. We then performed liver biopsy, and obtained a histological diagnosed primary biliary cirrhosis. Systemic lymph nodes decreased together with serum bile duct enzyme levels during treatment with ursodeoxycholic acid.

Abstract
We present a case of a 73-year-old man with multifocal autoimmune pancreatitis (AIP) in the pancreatic head and tail, and who had undergone sigmoidectomy and rectectomy 28 months before presenting to our department. Upon presentation, his serum IgG4 level was elevated at 267mg/dl, but tumor marker levels were within normal ranges. CT and MRI showed two localized pancreatic masses with delayed enhancement, but endoscopic retrograde pancreatography revealed neither stenosis nor dilatation of the main pancreatic duct. FDG-PET examination showed intense uptake in regions concordant with both tumors. The possibility of atypical AIP was a concern, but malignant tumor could not be clinically or radiologically excluded. Endoscopic ultrasonographic fine-needle aspiration biopsy was performed, but no malignant cells were detected. The patient underwent subsequent distal pancreatectomy. Histological evaluation of the tumors showed the presence of many IgG4-positive plasma cells without any evidence of malignancy.

Abstract
We have investigated the ultrafast spin dynamics in EuO thin films by time-resolved Faraday rotation spectroscopy. The photoinduced magnetization is found to be increased in a transient manner, accompanied with subsequent demagnetization. The dynamical magnetization enhancement showed a maximum slightly below the Curie temperature with prolonged tails toward both lower and higher temperatures and dominates the demagnetization counterpart at 55 K. The magnetization enhancement component decays in ~1 ns. The realization of the transient collective ordering is attributable to the enhancement of the f-d exchange interaction.

Abstract
AIMS/HYPOTHESIS The renal and cardiovascular protective effects of angiotensin receptor blocker (ARB) remain controversial in type 2 diabetic patients treated with a contemporary regimen including an angiotensin converting enzyme inhibitor (ACEI). METHODS We examined the effects of olmesartan, an ARB, on primary composite outcome of doubling of serum creatinine, endstage renal disease and death in type 2 diabetic patients with overt nephropathy. Secondary outcome included composite cardiovascular outcomes, changes in renal function and proteinuria. Randomisation and allocation to trial group were carried out by a central computer system. Participants, caregivers, the people carrying out examinations and people assessing the outcomes were blinded to group assignment. RESULTS Five hundred and seventy-seven (377 Japanese, 200 Chinese) patients treated with antihypertensive therapy (73.5% [n = 424] received concomitant ACEI), were given either once-daily olmesartan (10-40 mg) (n = 288) or placebo (n = 289) over 3.2 ± 0.6 years (mean±SD). In the olmesartan group, 116 developed the primary outcome (41.1%) compared with 129 (45.4%) in the placebo group (HR 0.97, 95% CI 0.75, 1.24; p = 0.791). Olmesartan significantly decreased blood pressure, proteinuria and rate of change of reciprocal serum creatinine. Cardiovascular death was higher in the olmesartan group than the placebo group (ten vs three cases), whereas major adverse cardiovascular events (cardiovascular death plus non-fatal stroke and myocardial infarction) and all-cause death were similar between the two groups (major adverse cardiovascular events 18 vs 21 cases, all-cause deaths; 19 vs 20 cases). Hyperkalaemia was more frequent in the olmesartan group than the placebo group (9.2% vs 5.3%). CONCLUSIONS/INTERPRETATION Olmesartan was well tolerated but did not improve renal outcome on top of ACEI. TRIAL REGISTRATION ClinicalTrials.gov NCT00141453.

Abstract
A 20-year-old man had suffered from dysphagia since primary school. Upper gastrointestinal and endoscopy examinations revealed severe circumferential stenosis of the upper intra-thoracic esophagus. Secondary stenosis due to factors such as inflammation did not appear present, so congenital esophageal stenosis (CES) was diagnosed. Dysphagia improved after two endoscopic balloon dilatations. Almost all cases of CES are treated in baby-hood, and individuals who remain untreated until adulthood are rare. Check ups and diagnoses should be made taking CES into consideration, even in adults.

Abstract
A 65-year-old woman who had diffuse hepatocellular carcinoma(HCC)with tumor thrombus of right portalvein(Vp3) and lung metastases(Stage IVB)was treated by single-agent therapy with tegafur/uracil(UFT). As a result, primary and metastatic tumors were not recognized by diagnostic imaging, with a noted decrease of AFP, AFP-L3 and PIVKA-II. Generally, oral chemotherapy for HCC is not recommended because of the low response rate. However, there have been some reports including the present case which have showed a marked response with UFT. We thus conclude that UFT can be an option with low risk of crucial adverse effects in the treatment of selected HCC patients.

Abstract
BACKGROUND AND AIM Several studies performed in Western countries demonstrate the association between sleep dysfunction and gastroesophageal reflux disease (GERD), especially when nighttime heartburn is present. The purpose of this study was to examine the prevalence and risk factors of sleep dysfunction, and the effect of rabeprazole on reflux symptoms and sleep dysfunction in Japanese GERD patients. METHODS A total of 134 GERD patients, including 82 patients with non-erosive reflux disease (NERD), were enrolled. Patients received rabeprazole 10 mg daily for 8 weeks. Patients were asked to complete both a frequency scale for symptoms of GERD (FSSG) questionnaire and a Pittsburgh Sleep Quality Index (PSQI) questionnaire at baseline and 8 weeks after treatment. RESULTS Sleep dysfunction defined as a PSQI score >5.5 was found in 70 (52.2%) of the GERD patients. NERD was significantly associated with sleep dysfunction compared to erosive reflux disease (OR 2.18, 95% CI 1.05-4.53). However, other factors, including nighttime heartburn, were not associated with sleep dysfunction. Rabeprazole treatment significantly decreased both the FSSG and the PSQI score. CONCLUSION The prevalence of sleep dysfunction was high among GERD patients. NERD was identified as a risk factor for sleep dysfunction. Use of a proton-pump inhibitor led to an effective decrease in sleep dysfunction. These results suggest a different pathogenesis of sleep dysfunction in Japanese GERD patients compared to GERD patients in Western countries. However, acid plays an important role in sleep dysfunction in all patients with GERD.
