Adult-onset Still's Disease Diagnosed during Puerperium with Liver Dysfunction in Pregnancy and Liver Failure of the Infant.

Most cases of liver dysfunction in pregnancy are pregnancy-related, but the onset of systemic autoimmune diseases is also differentiated. A 24-year-old woman presented with liver dysfunction at 28 weeks' gestation with suspected autoimmune hepatitis and started taking ursodeoxycholic acid. She gave birth prematurely at 35 weeks' gestation, and the infant presented with pancytopenia and liver failure but survived because of liver transplantation.

Primary Bile Duct Diffuse Large B-cell Lymphoma Diagnosed by Repeated Endoscopic Ultrasound-guided Fine-needle Aspiration and Endoscopic Retrograde Cholangiopancreatography.

A 54-year-old man was admitted with obstructive jaundice. Computed tomography showed common bile duct stricture and a tumor around the celiac artery. Repeated endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and endoscopic retrograde cholangiopancreatography (ERCP) as well as a laparotomic biopsy around the celiac artery were diagnostically unsuccessful.

Poor Sleep quality and health-related quality of life impact in adolescents with and without chronic immunosuppressive conditions during COVID-19 quarantine.

Objective: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.

Evaluation of ventricular systolic function by speckle tracking technique in patients with biliary atresia before and after liver transplantation.

To evaluate the ventricular function of patients with biliary atresia (BA) before and after liver transplantation using two-dimensional speckle tracking. Observational, analytical study with healthy control group, volunteers. We recruited patients from 0 to 18 years old who were candidates for liver transplantation and patients after six months of liver transplantation performed for BA from January 1997 to August 2015 at Children's Institute of São Paulo University Medical School.

Pruritus is common in patients with chronic liver disease and is improved by nalfurafine hydrochloride.

Pruritus is known to be a common complication in hepatitis patients, but the exact frequency and degree are not fully elucidated. Thus, we evaluated pruritus of 450 patients with chronic liver disease at our hospital. Pruritus was observed in 240 (53%) of the patients.

Utility of endoscopic ultrasonography-guided fine-needle biopsy (EUS-FNB) for diagnosing small subepithelial lesions (< 20 mm).

Aim: Subepithelial lesions (SELs) are defined as being located under the mucosa. Presently, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is commonly performed to diagnose SELs. With the development of new puncture needles, endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB), which allows for the acquisition of large tissue samples, has been proposed.

Clinical course of biliary-type sphincter of Oddi dysfunction: endoscopic sphincterotomy and functional dyspepsia as affecting factors.

Background And Study Aims: The objective of this study was to clarify the effectiveness of treatment selection for biliary-type sphincter of Oddi dysfunction by severe pain frequency and the risk factors for recurrence including the history of functional gastrointestinal disorder.

Patients And Methods: Thirty-six sphincter of Oddi dysfunction patients who were confirmed endoscopic retrograde cholangiopancreatography enrolled in this study. Endoscopic sphincterotomy was performed for type I and manometry-confirmed type II sphincter of Oddi dysfunction patients with severe pain (⩾2 times/year; endoscopic sphincterotomy group).

Rupture of Hepatic Pseudoaneurysm Formed Nine Years after Carbon Ion Radiotherapy for Hepatocellular Carcinoma.

An 83-year-old man with a history of carbon ion radiotherapy for hepatocellular carcinoma nine years ago presented to a primary care hospital with a fever and abdominal pain. He underwent computed tomography, which revealed the rupture of a hepatic pseudoaneurysm close to the fiducial marker for carbon ion radiotherapy and bleeding into the bile duct. He was successfully treated with transcatheter arterial embolization.

Clinical features and management of painless biliary type sphincter of Oddi dysfunction.

Objective: The objective of this study was to clarify the characteristics and management of painless biliary type sphincter of Oddi dysfunction (SOD).

Methods: From June 2002 to July 2018, 12 patients who had recurrent liver dysfunction with a dilated bile duct or acute cholestasis of unknown cause without biliary pain (painless SOD) were included in this study. These patients’ characteristics were compared with those of 36 patients with biliary type SOD based on the conventional definition (criteria-based SOD).

Appropriate Timing of Discontinuation of Tacrolimus Therapy for Refractory Ulcerative Colitis.

Background And Objectives: Tacrolimus is very effective at inducing remission in patients with refractory ulcerative colitis. However, the optimal time-point for the discontinuation of tacrolimus is controversial because administration of tacrolimus for > 3 months is currently not approved for insurance reimbursement in Japan. We conducted this study to determine the optimal time of discontinuation of tacrolimus in patients with ulcerative colitis.

A Diagnostically Challenging Case of Autoimmune Pancreatitis Due to Contamination of the Pathological Specimen with Early Gastric Cancer.

A 73-year-old man with worsened diabetes underwent abdominal computed tomography and was diagnosed with localized enlargement of the pancreatic tail. Based on the suspicion of autoimmune pancreatitis, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed. A cytologic examination showed findings suggestive of adenocarcinoma.

A case of gossypiboma diagnosed with transanal double-balloon enteroscopy.

Gossypiboma is an iatrogenic granuloma caused by retained surgical gauze. A 48-year-old woman with a history of cesarean section was incidentally found to have a pelvic mass on preoperative computed tomography examination for pectus excavatum. Abdominal enhanced computed tomography showed a 40-mm mass containing air in the pelvis.

Crohn's Disease with Mesalazine Allergy that Was Difficult to Differentiate from Comorbid Ulcerative Colitis.

An 18-year-old man diagnosed with ileocolonic Crohn's disease with circumferential strictures of the ascending colon started treatment with mesalazine and subsequently underwent right hemicolectomy. After surgery, the patient was started on adalimumab, and the clinical course was favorable. Nine months postoperatively, colonoscopy revealed granular mucosa with circumferential and continuous involvement from the transverse colon down to the rectum, findings which resembled ulcerative colitis.

Post-ERCP biliary complications in patients with biliary type sphincter of Oddi dysfunction.

Sphincter of Oddi dysfunction (SOD) has a high risk of post-ERCP pancreatitis. Cholangitis, colicky pain, and jaundice from cholestasis also occur after ERCP. However, these post-ERCP biliary complications have not been sufficiently evaluated in SOD.

Gangliocytic Paraganglioma with Carcinoma of the Ampulla of Vater.

The patient was a "73" -year-old woman who visited our hospital with the chief complaint of weight loss. Upper gastrointestinal endoscopy revealed an enlarged ampulla of Vater, and a biopsy led to a diagnosis of Group "4" gastric carcinoma; suspicious of adenocarcinoma. There were no findings suggesting invasion into the muscle layer of duodenum, despite tumor mass formation being observed in the sphincter of Oddi.

Tacrolimus versus anti-tumor necrosis factor agents for steroid-refractory active ulcerative colitis based on the severity of endoscopic findings: a single-center, open-label cohort study.

Background And Aims: At Saitama Medical Center, for remission induction in active ulcerative colitis (UC) patients with endoscopic evidence of severe disease, we tend to preferentially use tacrolimus (TAC) over anti-tumor necrosis factor (TNF)-α agents. We conducted this study to evaluate the validity of our therapeutic strategies.

Patients And Methods: This retrospective study was conducted in 52 steroid-refractory active UC patients with a Clinical Activity Index (CAI) score of ≥7 who were receiving remission induction therapy with TAC or anti-TNF-α agents.

Should Emergency Endoscopy be Performed in All Patients With Suspected Colonic Diverticular Hemorrhage?

Objective: We attempted to develop a scoring system for facilitating decision making regarding the performance of emergency endoscopy in patients with colonic diverticular hemorrhage.

Methods: This study involved analysis of the data of 178 patients who presented with hematochezia and were diagnosed as having colonic diverticular hemorrhage by colonoscopy. The patients were divided into 2 groups depending on whether the bleeding source was identified or not at the initial endoscopy (source-identified and source-not-identified groups), and on the basis of the results obtained, we established a scoring system for predicting successful identification of the bleeding source.

Risk factors of post- endoscopic retrograde cholangiopancreatography pancreatitis in biliary type sphincter of Oddi dysfunction in Japanese patients.

Objective: Suspected sphincter of Oddi dysfunction (SOD) is a well-known risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). The indication of ERCP for suspected SOD patients was very low in Japan compared to other countries. Therefore, the risk of PEP may be different in Japanese SOD patients.

Rapid Induction Therapy with Oral Tacrolimus in Elderly Patients with Refractory Ulcerative Colitis Can Easily Lead to Elevated Tacrolimus Concentrations in Blood: A Report of 5 Cases.

BACKGROUND Tacrolimus is reportedly effective for the treatment of refractory ulcerative colitis (UC). At our hospital, there has been an increase in the number of patients, including elderly patients, with refractory UC treated with tacrolimus. Here, we review the data from 5 patients with elderly-onset UC treated with tacrolimus as remission induction therapy.

Malignant transformation of a gastric hyperplastic polyp in a context of Helicobacter pylori-negative autoimmune gastritis: a case report.

Background: Gastric foveolar hyperplastic polyps (GFHPs) are common findings in clinical practice. GFHPs commonly arise in a background of chronic atrophic gastritis, including autoimmune gastritis (type A gastritis), and have a potential risk of malignant transformation.

Case Presentation: In 2005, a 55-year-old Japanese woman underwent upper endoscopy at another hospital and was found to have a pedunculated polyp (10 mm in diameter) on the greater curvature of the lower gastric body.
