[A Case of Epiploic Appendagitis after COVID-19].

Acute epiploic appendagitis is an uncommon cause of abdominal pain resulting from appendageal ischemia caused by torsion or thrombosis of the draining vein. It is frequently misdiagnosed as acute appendicitis or diverticulitis. The coronavirus disease 2019 (COVID-19) pandemic has changed how this rare disease is diagnosed.

Clinical Features and Long-Term Outcomes of Paediatric-Onset Inflammatory Bowel Disease in a Population-Based Cohort in the Songpa-Kangdong District of Seoul, Korea.

Background And Aims: The long-term outcomes of paediatric-onset inflammatory bowel disease [pIBD] in non-Caucasian populations are unknown. We therefore evaluated and compared the clinical features and long-term outcomes of pIBD with those of adult-onset IBD [aIBD] using a population-based cohort in the Songpa-Kangdong district of Seoul, Korea.

Methods: Clinical characteristics and prognoses were compared between the two groups: pIBD [defined as <18 years of age at diagnosis] and aIBD [18-59 years of age at diagnosis].

Changes in the Long-term Prognosis of Crohn's Disease between 1986 and 2015: The Population-Based Songpa-Kangdong Inflammatory Bowel Disease Cohort Study.

Background/aims: The long-term course of Crohn's disease (CD) has never been evaluated in non-Caucasian population-based cohorts. The aim of the present study was to evaluate the longterm prognosis of Korean CD patients in the well-defined population-based Songpa-Kangdong inflammatory bowel disease cohort.

Methods: Outcomes of disease and their predictors were evaluated for 418 patients diagnosed with CD between 1986 and 2015.

Clinical Characteristics and Long-term Prognosis of Elderly-Onset Ulcerative Colitis in a Population-Based Cohort in the Songpa-Kangdong District of Seoul, Korea.

Background/aims: We aimed to evaluate the clinical characteristics and long-term prognosis of elderly-onset ulcerative colitis (EOUC) in Korean patients over a 30-year period using a wellestablished population-based cohort in the Songpa-Kangdong district of Seoul, Korea.

Methods: Clinical characteristics and prognosis were compared between two groups: EOUC, defined as UC diagnosed in individuals aged ≥60 years and non-EOUC (N-EOUC), defined as UC diagnosed in individuals aged 18 to 59 years.

Results: We identified 99 patients with EOUC (10.

Long-term prognosis of ulcerative colitis and its temporal changes between 1986 and 2015 in a population-based cohort in the Songpa-Kangdong district of Seoul, Korea.

Objective: No population-based study has evaluated the natural course of UC over three decades in non-Caucasians. We aimed to assess the long-term natural course of Korean patients with UC in a population-based cohort.

Design: This Korean population-based, Songpa-Kangdong IBD cohort included all patients (n=1013) newly diagnosed with UC during 1986-2015.

Benign Gastric Ulcer with Epstein-Barr Virus Infection Mimicking Malignant Gastric Ulcer.

Epstein-Barr virus (EBV) is the cause of infectious mononucleosis, which is characterized by fever, lymphadenopathy, and sore throat. On the other hand, gastrointestinal symptoms of EBV infection like dyspepsia, abdominal pain are non-specific and rarely encountered, which means it is difficult to diagnose gastric involvement of EBV infection without suspicion. The relation between gastric carcinoma and gastric lymphoma associated with EBV infection is well defined, but relations with other EBV-associated gastrointestinal diseases such as gastritis and peptic ulcer disease have rarely been reported.

A 30-year Trend Analysis in the Epidemiology of Inflammatory Bowel Disease in the Songpa-Kangdong District of Seoul, Korea in 1986-2015.

Background And Aims: Although the incidence of inflammatory bowel disease [IBD] is increasing in Asia, data on long-term epidemiological trends are limited. We performed a 30-year longitudinal study to investigate temporal trends in the epidemiology of Crohn's disease [CD] and ulcerative colitis [UC] in Seoul, Korea.

Methods: This population-based study included 1431 IBD patients [418 CD, 1013 UC] diagnosed between 1986 and 2015 in the Songpa-Kangdong district of Seoul, Korea.

Predicting Factors for Successful Maturation of Autogenous Haemodialysis Fistulas After Salvage Percutaneous Transluminal Angioplasty in Diabetic Nephropathy: A Study on Follow-Up Doppler Ultrasonography.

Background: Maturation failure of autogenous arteriovenous fistula (aAVF) has been increasing after surgical procedures and the salvage percutaneous transluminal angioplasty (sPTA) for immature aAVF has been identified as an effective treatment modality.

Objectives: The aim of this study was to identify factors predicting successful aAVF maturation and to determine positive technical aspects of sPTA.

Patients And Methods: We retrospectively reviewed medical records and radiological images of 59 patients who had undergone sPTA for non-maturing aAVFs.

[A case of pleomorphic liposarcoma in a patient with Crohn's disease taking azathioprine].

Azathioprine is frequently used for the treatment of inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis. Lymphomas, squamous cell carcinomas, and undifferentiated pleomorphic sarcomas have been reported among patients receiving azathioprine therapy. Herein, we report a case of pleomorphic liposarcoma of chest wall which occurred in a 44-year-old man with Crohn's disease taking azathioprine.

[Is it useful to perform additional colonoscopy to detect unmatched lesion between positron emission tomography/computed tomography and colonoscopy?].

Background/aims: Incidentally detected focal 18F-fluorodeoxyglucose (FDG) uptake was compared with colonoscopy. We investigated the characteristics of colon adenomas which were revealed on PET/CT. Then we identified whether additional colonoscopy was necessary in patients with lesions which were revealed on PET/CT but had no matched lesions on colonoscopy.

MicroRNA-145 is regulated by DNA methylation and p53 gene mutation in prostate cancer.

MiR-145 is downregulated in various cancers including prostate cancer. However, the underlying mechanisms of miR-145 downregulation are not fully understood. Here, we reported that miR-145 was silenced through DNA hypermethylation and p53 mutation status in laser capture microdissected (LCM) prostate cancer and matched adjacent normal tissues.

Regulatory Role of mir-203 in Prostate Cancer Progression and Metastasis.

Purpose: Advanced metastatic prostate cancer (PCa) is a fatal disease, with only palliative therapeutic options. Though almost 80% of cases of metastatic PCa present bone metastasis, our current understanding of the molecular mechanisms that govern this metastatic dissemination remains fragmentary. The main objective of the present study was to identify microRNA (miRNA) genes that regulate metastatic PCa.

[Trial of moxifloxacin-containing triple therapy after initial and second-line treatment failures for Helicobacter pylori infection].

Background/aims: Proton-pump inhibitor (PPI)-based triple therapy for Helicobacter pylori eradication is widely used with considerable failure rate. Bismuth-based, second-line therapy is also associated with failures in more than 20% of cases in Korea. Our aim was to evaluate the efficacy and tolerability of third-line therapy containing moxifloxacin as a rescue in Korea.
