Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

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,...
Large Intestine01:09

Large Intestine

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
Inflammatory Bowel Disease I: Introduction01:26

Inflammatory Bowel Disease I: Introduction

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 “skip lesions” in which...
Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Inflammatory Bowel Disease II: Ulcerative Colitis01:20

Inflammatory Bowel Disease II: Ulcerative Colitis

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 BarrierA...

Area of Science:

  • Gastroenterology
  • Infectious Diseases
  • Proctology

Background:

  • Anal tuberculosis (TBC) is an uncommon manifestation of Mycobacterium tuberculosis infection.
  • Perianal TBC fissures present diagnostic challenges due to their infrequent occurrence.

Observation:

  • A case study of an adult female patient presenting with anal TBC fissure, characterized by bleeding and perianal pain.
  • The patient's chronic, painful, and bleeding anal fissure did not respond to conventional treatments, raising suspicion for a specific etiology.

Findings:

  • Histopathological examination via routine biopsy is crucial for diagnosing anal TBC fissure.
  • Early and accurate diagnosis is essential for effective management.

Implications:

  • Suspected diagnosis of anal TBC fissure should be considered in cases of chronic, treatment-resistant anal fissures.
  • Effective treatment involves a 3-drug regimen for 3 to 4 months, leading to a cure.
