Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

1.4K
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:

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

4.5K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Tooth Anatomy

2.8K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

2.1K
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...

Atypical Pneumonia01:14

Atypical Pneumonia

38
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

849
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Area of Science:

  • Pathology
  • Immunology

Background:

  • Granulomatous diseases share a common chronic inflammatory response characterized by microscopic granulomas.
  • These granulomas can arise from known infectious agents (bacteria, fungi, parasites) or unknown causes like autoimmune conditions, trauma, or neoplasms.
  • Despite histological distinctions, granulomatous diseases present diverse clinical features, sometimes not overtly inflammatory.

Purpose of the Study:

  • To elucidate the commonalities and distinctions in granulomatous diseases.
  • To differentiate between foreign body granulomas and immune granulomas.
  • To explore the underlying pathogenesis of granuloma formation.

Main Methods:

  • Histopathological examination of granulomas.
  • Review of clinical presentations of granulomatous diseases.
  • Comparative analysis of foreign body and immune granuloma formation.

Main Results:

  • Granulomas are the hallmark of chronic inflammation in these diseases.
  • Etiologies range from infectious agents to autoimmune and neoplastic processes.
  • Two primary types of granulomas, foreign body and immune, are identified.

Conclusions:

  • The pathogenesis of granuloma formation differs between foreign body and immune types.
  • Recognizing granuloma types is crucial for understanding disease mechanisms.
  • Further research into pathogenesis can clarify diverse clinical presentations.
