Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

535
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Liver Histology01:27

Liver Histology

769
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

325
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:

Liver Regeneration01:24

Liver Regeneration

3.3K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

230
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...

Area of Science:

  • Hepatology
  • Immunology
  • Pathology

Background:

  • Hepatic granulomas are collections of activated macrophages and inflammatory cells.
  • They can signify localized liver disease or systemic conditions like infections or autoimmune disorders.
  • Their prevalence in liver biopsies ranges from 1% to 15%.

Approach:

  • This review synthesizes current knowledge on granulomatous liver diseases.
  • Focuses on pathogenesis, histological features, and common etiologies.
  • Emphasizes the importance of liver biopsy for diagnosis and evaluation.

Key Points:

  • Granulomas may be incidental findings or indicate granulomatous hepatitis.
  • Potential progression to liver failure or cirrhosis in chronic cases.
  • Accurate diagnosis is essential for effective management.

Conclusions:

  • Understanding the pathogenesis, histology, and etiology of hepatic granulomas is vital.
  • Timely diagnosis and intervention can prevent severe liver complications.
  • This knowledge supports improved patient outcomes in granulomatous liver diseases.
