Inflammatory Bowel Disease II: Ulcerative Colitis01:20

Inflammatory Bowel Disease II: Ulcerative Colitis

34
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal...

Inflammatory Bowel Disease II: Crohn's Disease

1.6K
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Introduction

42
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows...

Inflammatory Bowel Disease I: Ulcerative Colitis

1.5K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease IV: Clinical Manifestations

33
Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

900
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Summary
This summary is machine-generated.

Ischemic colitis, often due to poor blood flow, rarely stems from vasculitis. This case highlights polyarteritis nodosa (PAN) as a cause of ischemic colitis, confirmed by colon histology.

Area of Science:

  • Gastroenterology
  • Vascular Medicine
  • Pathology

Background:

  • Ischemic colitis is a common intestinal injury resulting from reduced blood flow to the bowel.
  • Vasculitis is an uncommon cause of ischemic colitis.

Purpose of the Study:

  • To report a rare case of ischemic colitis caused by polyarteritis nodosa (PAN).
  • To emphasize the importance of considering vasculitis in the differential diagnosis of ischemic colitis.

Main Methods:

  • Case report of a 55-year-old man presenting with ischemic colitis.
  • Histological examination of a resected colon specimen.

Main Results:

  • The histological examination revealed polyarteritis nodosa (PAN) as the underlying cause of ischemic colitis.
  • The patient was diagnosed with PAN based on colon biopsy findings.

Conclusions:

  • Polyarteritis nodosa (PAN) can present as ischemic colitis.
  • Histopathological analysis of resected tissue is crucial for diagnosing vasculitis-induced ischemic colitis.
