01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
