The Thoracic Cage: Ribs01:20

The Thoracic Cage: Ribs

Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal facet...
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:
The Thoracic Cage: Sternum01:17

The Thoracic Cage: Sternum

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 process.

Pulmonary Tuberculosis II01:28

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 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...

Summary
This summary is machine-generated.

Nocardiosis is an opportunistic infection often seen in immunocompromised patients. This case highlights a rare presentation in a patient with psoriatic arthritis on immunosuppressive therapy.

Area of Science:

  • Infectious Diseases
  • Immunology
  • Rheumatology

Background:

  • Nocardiosis is an opportunistic infection primarily affecting immunocompromised individuals.
  • Pulmonary involvement is the most common presentation, but disseminated disease can occur.
  • Prolonged antibiotic therapy is standard for treating nocardiosis to prevent relapse.

Observation:

  • A case report details a patient undergoing extended immunosuppressive therapy for psoriatic arthritis.
  • The patient presented with a one-month history of right chest pain.
  • This clinical presentation prompted investigation into potential opportunistic infections.

Findings:

  • The patient's presentation suggests a possible atypical manifestation of nocardiosis.
  • Immunosuppression due to psoriatic arthritis treatment increases susceptibility to opportunistic infections.
  • Chest pain can be an indicator of pulmonary nocardiosis, even in non-classic presentations.

Implications:

  • This case underscores the importance of considering nocardiosis in immunocompromised patients with unusual symptoms.
  • Early diagnosis and appropriate prolonged antibiotic treatment are crucial for favorable outcomes.
  • Understanding the varied presentations of nocardiosis is vital for clinicians managing immunocompromised patients.
