Liver and exocrine pancreas Flashcards
What are the main causes of liver failure
Liver destruction, Hepatitis or alcoholic cirrhosis.
What is liver failure
The most severe clinical cansequence of liver disease is liver failure
What are the clinical manifestations in relation to the pathophysiology of liver failure
Manifestations of liver failure reflect the various synthesis, storage, metabolic, and elimination functions of the liver.
Hematologic Disorders: Liver failure can cause anemia, thrombocytopenia, coagulation defects, and leukopenia.
Malabsorption of the fat-soluble vitamin K
What is the treatment goal of alcoholic cirrhosis?
The treatment of liver failure is directed toward eliminating alcohol intake when the condition is caused by alcoholic cirrhosis
State the most (only) effective treatment in liver failure
Liver transplantation remains the only effective treatment
What is gastritis?
Gastritis is inflammation of the gastric mucosa, which can be acute or chronic, causing nausea, vomiting, epigastric pain, and sometimes hemorrhage.
What are common causes of acute gastritis?
Medications (NSAIDs, aspirin), alcohol, stress, bacterial toxins, uremia, chemotherapy, and radiation.
What is the primary cause of chronic gastritis?
Helicobacter pylori infection. (H.pylori infection)
Or autoimmune
How does H. pylori cause gastritis?
It produces urease, which disrupts mucosal defenses, leading to inflammation and increased cancer risk.
What are the symptoms of acute gastritis?
Heartburn, sour stomach, vomiting, hematemesis, and melena.
What is peptic ulcer disease?
It is a condition characterized by ulceration of the stomach or duodenal lining due to the breakdown of mucosal defenses.
What are the two main causes of peptic ulcers?
H. pylori infection and NSAID use.
How does H. pylori lead to ulcers?
It causes inflammation, increases acid secretion, and damages mucosal defenses.
What are the clinical manifestations of peptic ulcers?
Most important is theEpigastric pain,
other symptoms include:
nausea, vomiting, hematemesis, melena, and iron deficiency anemia.
How do symptoms differ between gastric and duodenal ulcers?
Gastric ulcers worsen with food, while duodenal ulcers improve with food.
How does food affect pain in gastric vs. duodenal ulcers?
Gastric ulcers worsen with food, while duodenal ulcers improve with food.
antacids can also help
What are clinical complications of peptic ulcers?
Hemorrhage, perforation and penetration, and gastric outlet obstruction.
How are peptic ulcers treated?
Eradication of helicobacter pylori, stop NSAIDs use, in case of gastric ulcer biopsies to rule out malignancy, endoscopic follow up to ensure ulcer healing.
What causes viral hepatitis?
Hepatotropic viruses (HAV, HBV, HCV, HDV, HEV).
How is hepatitis A transmitted?
Fecal-oral route via contaminated food or water.
How are hepatitis B and C transmitted?
Blood and body fluids, sexual contact, and perinatal transmission.
What are the clinical phases of hepatitis?
Prodromal (flu-like symptoms), Icterus (jaundice), and Recovery (symptom resolution).
What are the complications of chronic hepatitis?
Cirrhosis, liver failure, and hepatocellular carcinoma.
What is cirrhosis?
Chronic liver disease characterized by fibrosis and scarring, leading to liver dysfunction.
