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:

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...

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Pulmonary Tuberculosis I

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.
Mode of...
Pulmonary Tuberculosis IV01:26

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...

Pulmonary Tuberculosis V

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 progression...

Area of Science:

  • Pediatric infectious diseases
  • Gastroenterology
  • Hepatology

Background:

  • Abdominal tuberculosis (TB) is a significant global health concern, but hepatosplenic involvement is exceptionally rare in pediatric cases.
  • Early diagnosis and management are crucial for favorable outcomes in children with disseminated TB.

Observation:

  • A 7-year-old girl presented with persistent fever, cough, and significant hepatosplenomegaly.
  • Imaging studies revealed characteristic lesions in the liver and spleen.
  • Colonoscopy identified a partially obstructive, ulcerated mass in the cecum.

Findings:

  • Microbiological and histopathological analyses of intestinal and liver biopsies confirmed disseminated tuberculosis.
  • The findings support tuberculosis as the cause of the observed hepatosplenic and intestinal manifestations.

Implications:

  • This case underscores the importance of considering abdominal tuberculosis in the differential diagnosis of pediatric hepatosplenomegaly and gastrointestinal symptoms.
  • Highlights the diagnostic utility of combined imaging, endoscopy, and biopsy in complex pediatric TB cases.
  • Emphasizes the need for increased awareness of rare TB presentations in children to ensure timely and appropriate treatment.
