Pulmonary Tuberculosis II01:28

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...

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:

Acute Pharyngitis01:30

Acute Pharyngitis

305
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Pulmonary Tuberculosis I01:29

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.

Pulmonary Tuberculosis V

157
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 IV01:26

Pulmonary Tuberculosis IV

125
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...

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Radiology

Background:

  • Dacryoadenitis, an inflammation of the lacrimal gland, can present with orbital swelling.
  • Unresponsive orbital inflammation warrants investigation for less common causes like tuberculosis.

Purpose of the Study:

  • To report a case of orbital tuberculosis presenting as dacryoadenitis.
  • To highlight the diagnostic challenges and successful management of orbital TB.

Main Methods:

  • Clinical presentation of a young female with orbital swelling.
  • Diagnostic imaging including CT scan and ultrasonography.
  • Microbiological confirmation of Mycobacterium tuberculosis using Cartridge-based Nucleic Acid Amplification Test (CBNAAT).

Main Results:

  • CT revealed osteomyelitis of the lateral orbital wall and a cold abscess.
  • Abscess drainage and CBNAAT confirmed tuberculosis.
  • Antituberculosis treatment led to complete resolution and no recurrence over 2 years.

Conclusions:

  • Orbital tuberculosis should be considered in cases of dacryoadenitis unresponsive to antibiotics.
  • High index of suspicion is vital in TB-endemic regions.
  • Prompt diagnosis and treatment ensure favorable prognosis.
