Inflammatory Bowel Disease II: Crohn's Disease

1.5K
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: Introduction

920
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...

Inflammatory Bowel Disease I: Ulcerative Colitis

1.4K
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...

Assessment of the Rectum and Anus

1.8K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Appendicitis-II: Diagnostic Studies and Management

788
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

3.6K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Summary
This summary is machine-generated.

Pyoderma gangrenosum (PG) can be associated with colonic diverticulitis infection (DI). Surgical removal of diverticulitis successfully treated PG in two patients, suggesting a link between colonic inflammation and skin lesions.

Area of Science:

  • Dermatology
  • Gastroenterology
  • Immunology

Background:

  • The association between pyoderma gangrenosum (PG) and colonic diverticulitis infection (DI) is not well-established.
  • This report details two cases of PG that resolved after surgical intervention for DI.

Observation:

  • Two patients with PG and DI underwent sigmoidectomy.
  • One patient was an 83-year-old male with leg lesions and DI with abscesses.
  • The second patient was a 63-year-old female with severe PG, abdominal pain, and perforated sigmoid DI.

Findings:

  • Both patients experienced complete resolution of PG after sigmoidectomy.
  • PG healed without the need for corticosteroids or other immunosuppressants post-surgery.
  • Histological confirmation of PG and CT scans revealing DI were crucial for diagnosis.

Implications:

  • Colonic diverticulitis infection (DI) should be considered a potential systemic disease associated with PG.
  • Abdominal CT scans may detect asymptomatic DI in patients presenting with isolated PG.
  • Early diagnosis and surgical intervention for DI can lead to PG remission and prevent severe gastrointestinal complications.
