A TNBS-Induced Rodent Model to Study the Pathogenic Role of Mechanical Stress in Crohn's Disease
Published on: March 1, 2022
[Gastroduodenal Crohn disease. Presentation with a case report]
Summary
This study discusses Crohn's disease isolated to the duodenum, a rare presentation. Diagnosis relies on imaging and clinical signs due to low biopsy success rates for Crohn's disease.
Area of Science:
- Gastroenterology
- Inflammatory Bowel Disease
- Surgical Pathology
Background:
- Crohn's disease (a chronic inflammatory bowel disease) typically affects the terminal ileum and colon.
- Isolated duodenal Crohn's disease is an uncommon manifestation, presenting diagnostic challenges.
Observation:
- The case study focuses on the infrequent isolated occurrence of Crohn's disease within the duodenum.
- Clinical presentation, radiological imaging, and endoscopic examination are crucial for diagnosis.
- Segmentary stenosis in the duodenum is a key diagnostic indicator.
Findings:
- Radiological and endoscopic findings of segmentary stenosis are primary diagnostic references.
- Histological confirmation via endoscopic biopsies has a low success rate for detecting granulomatous inflammation.
- A comprehensive synopsis of all findings is essential for accurate diagnosis.
Implications:
- Highlights the importance of considering Crohn's disease in duodenal stenosis differential diagnoses.
- Emphasizes the diagnostic utility of imaging and endoscopic visualization when biopsies are inconclusive.
- Underscores the need for a multidisciplinary approach in diagnosing rare gastrointestinal conditions.

Gastroesophageal Reflux Disease II: Clinical Features and Management
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Inflammatory Bowel Disease II: Crohn's Disease
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 transmural...

Peptic Ulcer Disease III: Clinical Manifestations and Complications
Duodenal UlcersDuodenal ulcers are the most common form of peptic ulcer disease, presenting with chronic, intermittent epigastric pain. Pain typically appears 2–3 hours after meals, especially when the stomach is empty, often waking patients at night. It is characteristically relieved by food or antacids (“pain–food–relief”). Some patients remain asymptomatic until complications like bleeding or perforation emerge, particularly with NSAID or anticoagulant use.Gastric UlcersGastric ulcers share...
Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
