UNLABELLED: Infectious mononucleosis (IM), the most common presentation of acute Epstein Barr virus (EBV) infection, typically presents with fever, pharyngitis and lymphadenopathy. We describe an unusual case of IM presenting as acute sinusitis. A 25 year-old male presented to the emergency department with worsening right frontal sinus pain along with fever, chills, and greenish nasal discharge for 3 weeks. Laboratory workup showed leukocytosis with high lymphocyte counts as well as transaminitis...

Schwannoma is a rare benign neurogenic tumor arising from the Schwann cells of peripheral nerves. A 77-year-old man presented with progressively worsening left nasal block and hyposmia for the past six months. Nasal endoscopy revealed a polypoidal reddish mass occupying the left middle meatus. The biopsy was in favor of ancient schwannoma. Endoscopic transnasal excision of the mass arising from the left nasal septum was performed. A middle meatal antrostomy was also performed. The tumor cells were positive for S100 protein...

OBJECTIVES: We performed a clinical study comparing early-onset and late-onset conventional colorectal adenomas (CCRAs) since little is known about the differences in their characteristics. METHODS: Pearson's chi-square test and the Kruskal‒Wallis test were used to compare basic information. MCAR tests and multiple imputation were performed to complete missing values. Multivariate logistic analysis and propensity score matching were used to identify the risk factors for recurrence...

BACKGROUND AND AIMS: Increasing the adenoma detection rate (ADR) helps reduce the risk of post-colonoscopy colorectal cancer. Texture and Color Enhancement Imaging (TXI) improves ADR by enhancing the brightness and contrast of endoscopic images. Endocuff Vision (ECV) is a mucosal exposure device that helps flatten the colonic folds. The benefit of combining TXI with ECV has not been studied previously. Thus, we aimed to compare the ADR between using TXI combined with ECV and TXI alone...

BACKGROUND: Diet may induce clinical remission in dogs with chronic enteropathy (CE). Elemental diets (EDs), providing protein as amino acids, modulate intestinal immunity and microbiome in rodents and humans. HYPOTHESIS: Evaluate the impact of an amino acid-based kibble (EL) on CE clinical activity and gastrointestinal (GI)-relevant variables. ANIMALS: Client-owned dogs (n = 23) with inadequately controlled CE. METHODS: Prospective, uncontrolled clinical trial...

INTRODUCTION: Radiofrequency ablation (RFA) and hybrid argon plasma coagulation (H-APC) are established thermal ablation techniques for eradicating Barrett's esophagus after endoscopic resection. This study aimed to compare RFA with H-APC in relation to safety, effectiveness and eradication rates. METHODS: After endoscopic resection, patients were randomly assigned to H-APC or RFA. A simplified H-APC technique was applied at 60 W. RFA was used with a 90° focal catheter and a simplified protocol of 12 J/cm2  × 3 or with a Halo 360° balloon and 10 J/cm2 /cleaning/10 J/cm2 ...

OBJECTIVES: Several clinical disease activity indices (DAIs) have been developed to noninvasively assess mucosal healing in pediatric Crohn's disease (CD). However, their clinical application can be complex. Therefore, we present a new way to identify the most informative biomarkers for mucosal inflammation from current markers in use and, based on this, how to obtain an easy-to-use DAI for clinical practice. A further aim of our proof-of-concept study is to demonstrate how the performance of such a new DAI can be compared to that of existing DAIs...

BACKGROUND: Endoscopic band ligation (EBL) and radiofrequency ablation (RFA) have emerged as alternative therapies of gastric antral vascular ectasia (GAVE) in addition to endoscopic thermal therapy (ETT), but the optimum choice remains inconclusive. AIM: We conducted a meta-analysis in order to compare these three treatments for GAVE. METHODS: We searched the electronic databases of PubMed, Embase and Cochrane Central Register of Controlled Trials without any language restrictions and also performed a manual literature search of bibliographies located in both retrieved articles and published reviews for eligible publications prior to December 8, 2021...

BACKGROUND: Contrast-enhanced ultrasonography (CEUS) of the bowel wall has been suggested as an alternative imaging modality for the follow-up of children with Crohn's disease. To demonstrate the feasibility and clinical usefulness of CEUS in the estimation of Crohn's disease activity in children with endoscopy as the reference standard. METHOD: In this prospective study, 30 pediatric patients with Crohn's disease (24 males and 6 females; median age 14 years) underwent CEUS from December 2020 to August 2021...

BACKGROUND: Evidence of small-bowel capsule endoscopy (SBCE) for evaluating lesions in Crohn's disease (CD) is lacking. We aimed to clarify the effectiveness and safety of SBCE in a large sample of patients with CD. METHODS: This multicenter prospective registration study recorded the clinical information and SBCE results of patients with definitive CD (d-CD) or suspected CD (s-CD). The primary outcomes were the rates of successful assessment of disease activity using SBCE, definitive diagnosis of CD, and adverse events...

INTRODUCTION: Chronic radiation proctitis is a common chronic complication of malignant pelvic diseases after pelvic radiation therapy. Although, the incidence has decreased after advent of intensity-modulated radiotherapy due to better control of radiation dose to rectum. In the era of conventional two-field radiotherapy to pelvis, this was a common complication usually presenting after 1-2 years of treatment completion. Rectal bleeding caused by radiation proctitis is difficult to manage...

BACKGROUND: X-linked severe combined immunodeficiency is caused by IL2RG gene mutation. Several variations have been identified in the IL2RG gene, which potentially can prevent the production of nonfunctional proteins. Herein, a novel X-linked variant in the IL2RG gene is reported in twin brothers, associated with inflammatory bowel symptoms. CASE PRESENTATION: The patients were 26-month-old monozygotic twin middle-eastern males with failure to thrive and several inpatient admissions due to severe chronic nonbloody diarrhea that started at the age of 12 months...

BACKGROUND:  Texture and color enhancement imaging (TXI) was recently proposed as a substitute for standard high definition white-light imaging (WLI) to increase lesion detection during colonoscopy. This international, multicenter randomized trial assessed the efficacy of TXI in detection of colorectal neoplasia. METHODS:  Consecutive patients aged ≥ 40 years undergoing screening, surveillance, or diagnostic colonoscopies at five centers (Italy, Germany, Japan) between September 2021 and May 2022 were enrolled...

INTRODUCTION: A large proportion of small bowel lesions in Crohn's disease (CD) may exist beyond the reach of ileocolonoscopy and there is no gold standard imaging modality to screen them, suggesting the need for optimal biomarkers. We aimed to compare the usefulness of C-reactive protein (CRP), faecal calprotectin (FC), and leucine-rich alpha-2 glycoprotein (LRG) in determining small bowel lesions of CD. METHODS: This was a cross-sectional observational study. CRP, FC, and LRG were prospectively measured in patients with quiescent CD who underwent imaging examinations (capsule or balloon-assisted endoscopy, magnetic resonance enterography, or intestinal ultrasound) selected by the physician in clinical practice...

Follicular lymphoma (FL) is the most common low-grade lymphoma, and although nodal FL is highly responsive to treatment, the majority of patients relapse repeatedly, and the disease has been incurable with a poor prognosis. However, primary FL of the gastrointestinal tract has been increasingly detected in Japan, especially due to recent advances in small bowel endoscopy and increased opportunities for endoscopic examinations and endoscopic diagnosis. However, many cases are detected at an early stage, and the prognosis is good in many cases...

BACKGROUND: Subacute and chronic long-term effects of coronavirus disease 2019 (COVID-19) in different organ systems have been studied in post-COVID patients recently. COVID-19 may cause gastrointestinal (GI) system findings due to the presence of its receptor, angiotensin converting enzyme type 2 (ACE2), which is extensively expressed in the GI tract. In this study, we aimed to evaluate the post-infectious histopathological alterations of COVID-19 in pediatric patients who had GI symptoms...

The current standard of care for colon cancer surveillance relies heavily on white light endoscopy (WLE). However, dysplastic lesions that are not visible to the naked eye are often missed when conventional WLE equipment is used. Although dye-based chromoendoscopy shows promise, current dyes cannot delineate tumor tissues from surrounding healthy tissues accurately. The goal of the present study was to screen various phthalocyanine (PC) dye-loaded micelles for their ability to improve the direct visualization of tumor tissues under white light following intravenous administration...

PURPOSE OF REVIEW: Thermal ablatives therapies have seen an expanding role in gastrointestinal endoscopy during the last years. The aim of this review is to give an overview of the currently available techniques. RECENT FINDINGS: In the upper gastrointestinal tract, mainly in early Barrett's neoplasia, endoscopic ablation strategies ranging from RFA to Hybrid-APC are, together with resection strategies, the main part of the armamentarium. In the small intestine, argon plasma coagulation (APC) can be effectively used for the treatment of angiodysplasias...

BACKGROUND: RICAP is a recognized adverse effect of radiation therapy (RT) that can adversely affect cancer patients' quality of life. Data on the clinical characteristics and outcomes of RICAP are scarce. We aimed to analyze the clinical and endoscopic characteristics of acute or chronic radiation-induced colitis and proctopathy (ARICAP and CRICAP) based on symptom onset after RT (≤ or >45 days, respectively). METHODS: This is a retrospective observational study of a single tertiary cancer center, from January 2010 and December 2018, of cancer patients with endoscopically confirmed ARICAP and CRICAP...

BACKGROUND: The usefulness of leucine-rich alpha 2 glycoprotein (LRG) to evaluate Crohn's disease (CD) activity differs among various intestinal lesions. We aimed to evaluate the association between endoscopic disease activity based on the Simple Endoscopic Score for Crohn's disease (SES-CD) and LRG level separately for small intestinal and colonic lesions. METHODS: We examined the correlation between LRG level and SES-CD and performed receiver operating characteristic (ROC) analysis to determine the LRG cutoff value in 141 patients who underwent endoscopy (total 235 measurements)...
