Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

546
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 I

427
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 IV

246
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 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...

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...

Primary Lymphoid Organs01:16

Primary Lymphoid Organs

12.1K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Area of Science:

  • Neurology
  • Infectious Diseases
  • Ophthalmology

Background:

  • Tuberculosis (TB) can manifest with diverse neurological complications.
  • Optic neuritis is typically associated with immune-mediated conditions.
  • Diagnosing extrapulmonary TB can be challenging, especially in immunocompetent individuals.

Purpose of the Study:

  • To report a rare presentation of lymph node tuberculosis (TB) in an immunocompetent adolescent.
  • To highlight the diagnostic challenges of TB presenting as optic neuritis.
  • To emphasize the importance of considering TB in atypical neurological presentations.

Main Methods:

  • Case report of an immunocompetent teenage girl with bilateral optic neuritis.
  • Clinical evaluation including detailed history and neurological examination.
  • Advanced imaging with whole-body PET/MR.
  • Targeted lymph node biopsy for histopathological confirmation.

Main Results:

  • The patient presented with bilateral optic neuritis, initially suspected to be immune-mediated.
  • Unusual features included transient visual obscurations, prominent disc swelling, and lack of supportive laboratory findings for immune causes.
  • Whole-body PET/MR revealed extensive mediastinal and supraclavicular lymphadenopathy.
  • Despite negative interferon gamma release assay and normal chest X-ray, lymph node biopsy confirmed TB.

Conclusions:

  • Lymph node tuberculosis can present atypically with neurological symptoms like optic neuritis.
  • A high index of suspicion and comprehensive diagnostic workup are crucial for TB diagnosis in unusual presentations.
  • Integrated imaging modalities and targeted biopsies are vital for confirming TB in challenging cases.
