Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

277
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:

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Pulmonary Tuberculosis II

202
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...

Pulmonary Tuberculosis I

210
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Inflammatory Bowel Disease I: Ulcerative Colitis

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...

Area of Science:

  • Gastroenterology
  • Oncology
  • Infectious Diseases

Background:

  • Colorectal cancer screening can detect early signs like fecal occult blood.
  • Ascending colon lesions may present with non-specific symptoms, complicating diagnosis.
  • Intestinal tuberculosis is an infectious disease that can mimic other gastrointestinal pathologies.

Purpose of the Study:

  • To report a unique case of ascending colon cancer coexisting with intestinal tuberculosis.
  • To emphasize the importance of considering co-infections in gastrointestinal malignancy diagnosis.
  • To highlight diagnostic challenges and pathological findings in such rare presentations.

Main Methods:

  • Initial screening with fecal occult blood test.
  • Diagnostic colonoscopy revealing ulcerative and stenotic lesions in the ascending colon.
  • Biopsy and histopathological examination for definitive diagnosis.
  • Surgical resection (laparoscopic right colectomy) and subsequent pathological analysis.

Main Results:

  • Colonoscopy identified two circular narrowing sections and ulcers in the ascending colon.
  • Biopsy confirmed well-differentiated adenocarcinoma.
  • Pathological examination of resected tissue revealed adenocarcinoma, caseous granuloma, and acid-fast bacteria, indicative of tuberculosis.
  • Coexistence of ascending colon cancer and intestinal tuberculosis was confirmed.

Conclusions:

  • Ascending colon cancer can present concurrently with intestinal tuberculosis.
  • Comprehensive histopathological analysis is crucial for diagnosing coexisting conditions.
  • This case underscores the need for a broad differential diagnosis in patients with gastrointestinal symptoms and lesions.
