Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

93
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

458
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Gastritis-II: Pathophysiology

347
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

378
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Area of Science:

  • Hepatology
  • Immunology
  • Gastroenterology

Background:

  • Primary biliary cholangitis (PBC) is the most prevalent autoimmune liver disease.
  • It involves chronic inflammation of small bile ducts.

Purpose of the Study:

  • To summarize the multifactorial pathophysiology of Primary Biliary Cholangitis (PBC).
  • To highlight key contributing factors in PBC development.

Main Methods:

  • Literature review of autoimmune liver diseases.
  • Analysis of pathophysiological mechanisms in PBC.
  • Synthesis of data on genetic, epigenetic, and environmental factors.

Main Results:

  • PBC pathophysiology is multifactorial.
  • Key elements include immune dysregulation and biliary epithelial cell damage.
  • Genetic, epigenetic, gut-liver axis, and environmental factors play significant roles.

Conclusions:
