Inflammatory Bowel Disease I: Ulcerative Colitis01:27

Inflammatory Bowel Disease I: Ulcerative Colitis

651
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 II: Crohn's Disease

715
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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

653
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...

Histology of the Small Intestine01:27

Histology of the Small Intestine

2.9K
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

Histology of the Large Intestine01:26

Histology of the Large Intestine

2.4K
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

943
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Area of Science:

  • Gastroenterology
  • Histopathology

Background:

  • Microscopic colitis, encompassing collagenous and lymphocytic colitis, is increasingly diagnosed.
  • It presents with non-bloody diarrhea, urgency, and abdominal pain, significantly reducing quality of life.

Purpose of the Study:

  • To summarize the diagnosis, symptoms, and treatment of microscopic colitis.

Main Methods:

  • Diagnosis involves colonoscopy with biopsies showing characteristic histological findings.
  • Identifying and discontinuing causative medications like PPIs, NSAIDs, and SSRIs is a key step.

Main Results:

  • Budesonide is an effective, licensed treatment for persistent microscopic colitis symptoms.
  • Treatment aims to control symptoms and improve patient health-related quality of life.

Conclusions:

  • Early identification and management of microscopic colitis are crucial.
  • Discontinuation of inciting medications and use of budesonide are effective therapeutic strategies.
