Pulmonary Tuberculosis V01:28

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...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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:

Skin Cancer

6.7K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

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...

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.

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Microbiology

Background:

  • Tuberculosis Verrucosa Cutis (TBVC) is a rare, verrucous form of cutaneous tuberculosis.
  • It results from direct skin inoculation in immunocompetent individuals with moderate to high immunity.
  • The incidence of cutaneous tuberculosis has significantly declined in Western countries and India.

Observation:

  • Recent studies indicate a resurgence in the Indian subcontinent, with prevalence rates of 0.7% and 0.26%.
  • This case presents an immunocompetent individual with an indolent and extensive manifestation of TBVC.
  • The clinical presentation underscores the potential for significant skin involvement.

Findings:

  • Histopathology is crucial for diagnosing TBVC.
  • Empirical antitubercular therapy can serve as an adjunct diagnostic tool.
  • The indolent nature of the disease can lead to extensive skin lesions.

Implications:

  • This case emphasizes the importance of considering TBVC in differential diagnoses, even in immunocompetent individuals.
  • Accurate diagnosis through histopathology and therapeutic trials is vital for effective management.
  • Understanding the epidemiology and clinical presentation aids in recognizing this rare form of tuberculosis.
