Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

1.3K
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 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 IV01:26

Pulmonary Tuberculosis IV

467
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 I

801
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 V

520
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...

The Thoracic Cage: Sternum01:17

The Thoracic Cage: Sternum

5.5K
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid...

Area of Science:

  • Infectious Diseases
  • Osteomyelitis
  • Public Health

Background:

  • Tuberculosis (TB) is a major global health concern, with Mycobacterium tuberculosis infecting a substantial percentage of the world's population.
  • Tuberculous sternal osteomyelitis is an uncommon presentation of TB.

Observation:

  • The case involved tuberculous osteomyelitis of the sternum.
  • This specific manifestation presented with symptoms including fever, weight loss, and chest wall lesions.
  • Computed tomography (CT) scans were utilized to assess the thoracic extent of the condition.

Findings:

  • Diagnosis was confirmed using standard microbiologic methods.
  • The patient's sternal osteomyelitis was not linked to pulmonary tuberculosis.
  • Effective treatment involved a four-drug anti-tuberculous regimen.

Implications:

  • Highlights the potential for extrapulmonary TB presentations, such as sternal osteomyelitis.
  • Emphasizes the importance of considering TB in cases of sternal osteomyelitis, even without apparent pulmonary disease.
  • Reinforces the efficacy of standard four-drug anti-TB therapy for this rare manifestation.
