Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

1.8K
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 II

2.5K
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...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

7.2K
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

952
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...

Pulmonary Hypertension: Classification and Pathogenesis

906
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Area of Science:

  • Immunology
  • Pathology
  • Internal Medicine

Background:

  • Sarcoidosis is a systemic disease defined by non-necrotizing granulomas in any organ.
  • Lungs and lymph nodes are most commonly affected, but it can impact multiple organ systems.
  • The disease course varies from asymptomatic to chronic, with potential for spontaneous remission.

Purpose of the Study:

  • To provide a comprehensive overview of sarcoidosis.
  • To detail clinical manifestations, including cutaneous lesions and systemic involvement.
  • To outline diagnostic procedures, historical context, etiopathogenesis, and current treatments.

Main Methods:

  • Literature review of sarcoidosis.
  • Synthesis of information on clinical features, diagnosis, and treatment.
  • Emphasis on the role of cutaneous lesions as indicators of systemic disease.

Main Results:

  • Sarcoidosis presents with non-necrotizing granulomas, commonly in the lungs and lymph nodes.
  • Clinical features range from asymptomatic to chronic, with diverse systemic manifestations (respiratory, hepatic, ocular, cardiac, neurologic, etc.).
  • Cutaneous lesions can precede or accompany systemic involvement.

Conclusions:

  • Sarcoidosis is a complex systemic disease requiring a multidisciplinary approach.
  • Early recognition of cutaneous manifestations can aid in diagnosing systemic sarcoidosis.
  • Current treatment modalities offer management options for various manifestations.
