Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

2.2K
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...

Rous Sarcoma Virus (RSV) and Cancer

6.6K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Pulmonary Tuberculosis III

1.5K
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

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.

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

10.3K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Area of Science:

  • Immunology
  • Dermatology
  • Pathology

Background:

  • Sarcoidosis involves noncaseating granulomatous inflammation in multiple organs.
  • The skin is the third most commonly affected organ in North America.
  • Disease etiology involves genetic and environmental factors in susceptible individuals.

Purpose of the Study:

  • To summarize the key aspects of sarcoidosis, focusing on its dermatological manifestations.
  • To highlight the classification of skin lesions in sarcoidosis.

Main Methods:

  • Review of existing literature on sarcoidosis.
  • Analysis of clinical and pathological features of the disease.

Main Results:

  • Sarcoidosis presents with diverse clinical manifestations influenced by race, ethnicity, and gender.
  • Skin lesions are categorized as specific (with granulomas) or nonspecific (without granulomas).

Conclusions:

  • Sarcoidosis is a complex systemic disease with significant dermatological involvement.
  • Understanding the varied presentation and classification of skin lesions is crucial for diagnosis and management.
