Mass-forming isolated ischemic necrosis of the cecum mimicking malignancy: Clinicopathologic features of 11 cases.

Isolated ischemic necrosis of the cecum (INC) is an uncommon benign condition that occurs most often in elderly patients. The clinical presentation and radiographic findings often mimic acute appendicitis or malignancy. This study aimed to investigate the clinicopathologic features of mass-forming INC.

Identifying Risk Factors of Major Adverse Cardiac Events in Patients With Ulcerative Colitis: A Retrospective Japanese Claims Data Analysis.

Background And Aim: We conducted a retrospective study to identify incidence rates and potential risk factors of major adverse cardiac events (MACE) in Japanese patients with ulcerative colitis (UC), as existing data are scarce, inconsistent, and provide limited representation of the real-world situation of MACE in Japan.

Methods: We utilized administrative claims data, collected between January 2013 and December 2022, from Medical Data Vision, Japan. Patients (aged ≥ 20 years) diagnosed with UC within ± 1 month of the prescription date during the study period were included in the incident cohort.

Aplastic Anemia With Non-Occlusive Mesenteric Ischemia.

This case highlights the multifaceted challenges of managing aplastic anemia, especially when complicated by non-occlusive mesenteric ischemia (NOMI). The patient's clinical course underscores the importance of a conservative, multidisciplinary approach in balancing the risks of invasive procedures with the need for effective diagnostics and treatment. Recognizing the risks associated with pancytopenia, including life-threatening bleeding and infections, is critical in managing such patients.

Comorbidity and Disease Activity in Multiple Sclerosis.

Importance: Multiple studies suggest that comorbidity worsens clinically relevant outcomes in multiple sclerosis (MS), including the severity of disability at diagnosis and rate of disability worsening after diagnosis. However, less is known regarding the association of comorbidity with measures of disease activity, such as relapse rate and magnetic resonance imaging lesion accrual, which are relevant to clinicians and clinical trialists.

Objective: To evaluate the association of comorbidities with disease activity in clinical trials of disease-modifying therapies (DMTs) in populations with MS.

68 Ga-FAPI PET/CT Depicted the Fibrosis of Ischemic Colitis.

Ischemic colitis is the most common form of ischemic bowel disease; identification of ischemic colitis with PET/CT is rare. We present a case of unexplained ischemic colitis in a 66-year-old man who underwent 18 F-FDG PET/CT to exclude intestinal malignancy and was subsequently recruited in a clinical trial regarding 68 Ga-FAPI. 18 F-FDG PET/CT showed intense activity in the intestinal lumen where mucosa had chronic inflammation.

Anorectal hemangioma, a rare cause of lower gastrointestinal bleeding, treated with selective embolization: A case report.

Background: Anorectal hemangioma is a rare and frequently misdiagnosed cause of lower gastrointestinal (GI) bleeding. Here, we present a minimally invasive therapy with selective embolization.

Case Summary: A 21-year-old male patient experienced painless rectal bleeding since childhood and was treated for ulcerative colitis.

Endoscopic findings of immune checkpoint inhibitor-related gastrointestinal adverse events.

The use of immune checkpoint inhibitors (ICIs) for the treatment of various malignancies is increasing. Immune-related adverse events can occur after ICI administration, with gastrointestinal adverse events constituting a significant proportion of these events. When ICI-related diarrhea/colitis is suspected, endoscopic evaluation is recommended to differentiate it from other etiologies and assess the severity of colitis.

A case of abdominal aortic aneurysm presenting with multiple organs embolization.

Background: Distal embolization as the first manifestation of an abdominal aortic aneurysm (AAA) is relatively rare. AAAs presenting with multiple organs embolization are rarer and serious systemic conditions. There are no reports of life-saving outcomes in patients with AAAs presenting with multiple organs embolization prior to surgery.

Cardiovascular magnetic resonance reveals myocardial involvement in patients with active stage of inflammatory bowel disease.

Background: Active inflammatory bowel disease (A-IBD) but not remission (R-IBD) has been associated with an increased risk of cardiovascular death and hospitalization for heart failure.

Objectives: Using cardiovascular magnetic resonance (CMR), this study aims to assess adverse myocardial remodeling in patients with IBD in correlation with disease activity.

Methods: Forty-four IBD patients without cardiovascular disease (24 female, median-age: 39.

National trends in hospitalizations for gastrointestinal bleeding in Japan.

Gastrointestinal bleeding (GIB) is a significant public health concern, predominantly associated with high morbidity. However, there have been no reports investigating the trends of GIB in Japan using nationwide data. This study aims to identify current trends and issues in the management of GIB by assessing Japan's national data.

Ischemic Colitis in a Middle-Aged Man With COVID-19: Case Report and Review of Literature.

Introduction: Coronavirus disease 2019 (COVID-19) was a pandemic that began in 2019 and continues to have morbid and deadly consequences throughout the world. During the beginning of the pandemic, many considered older adults and immunocompromised younger adults to be the only populations at risk for the severe consequences of COVID-19. Throughout the pandemic, this was proven wrong with several case reports and studies showing that relatively younger adults can also suffer serious consequences from this perplexing virus.

A case of delayed necrosis of reconstructed colon after esophagectomy.

We report a very rare case of delayed necrosis of the reconstructed colon 6 months after esophagectomy.A 67-year-old male patient had undergone esophagectomy with gastric tube reconstruction for esophageal cancer in 2014. Subsequently, total gastrectomy and ileo-colon reconstruction via a retrosternal route was performed for gastric tube cancer in 2022.

Soccer Game Turned Bloody: A Case of Exercise-Induced Ischemic Colitis.

Ischemic colitis (IC) should be considered as a cause for gastrointestinal symptoms in patients with recent vigorous physical activity. Vasoconstriction driven by increased sympathetic tone during exercise is believed to mediate exercise-induced IC. In this report, a 21-year-old man with no medical history developed self-resolving, sudden-onset hematochezia and abdominal pain after playing in a collegiate soccer match for 90 minutes.

Prevalence and predictive value of sarcopenia in hospitalized patients with ischemic colitis.

Ischemic colitis (IC) and sarcopenia are associated with aging and multiple comorbidities. We aimed to investigate the prevalence and predictive role of sarcopenia in patients with IC. We retrospectively analyzed 225 hospitalized patients (median age, 72 years; women, 67.
