Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

514
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

5.5K
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 III01:31

Pulmonary Tuberculosis III

487
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 I01:29

Pulmonary Tuberculosis I

358
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

5.0K
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...

Cardiomyopathy IV: Restrictive Cardiomyopathy

77
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Granulomatous inflammation can manifest in various dermatological conditions.
  • Facial plaque presentation can be influenced by patient demographics and skin characteristics.

Observation:

  • A 52-year-old woman with darker skin presented with pink, elevated, granulomatous, indurated facial plaques, including nasal alae.
  • A 55-year-old woman with lighter skin presented with orange and pink, elevated, granulomatous, indurated facial plaques.

Findings:

  • Skin tone appears to influence the color and subtle morphology of facial granulomatous plaques.
  • The core features of granulomatous, elevated, and indurated plaques were consistent across both cases.

Implications:

  • Understanding these variations is crucial for accurate dermatological diagnosis.
  • Further research may elucidate the specific mechanisms behind skin tone-related differences in inflammatory dermatoses.
