Stomach Pathology Flashcards
____ (Acute/Chronic) gastritis is erosive, whereas ____ (acute/chronic) gastritis is nonerosive.
Acute; chronic
Where does type A chronic gastritis occur? Where does type B occur?
Fundus/body; antrum
Name some causes of acute gastritis.
NSAIDs, alcohol, stress, uricemia, burns, brain injury
A patient with severe burns develops which complication of acute gastritis?
Curling ulcer (burned by the Curling iron)
A man with brain injury acutely develops raw, burning epigastric pain. He should be treated to prevent which complication?
Cushing ulcers (remember, always cushion the brain)
In a patient with type A (fundal) gastritis, the autoantibodies are directed against what?
Parietal cells
Type A (fundal) gastritis is characterized by what two pathologic states?
Type A is caused by pernicious Anemia and Achlorhydria (A comes before B—pernicious Anemia is Autoimmune in first part of stomach)
Type B (antral) gastritis is caused by infection with what organism?
Type B is caused by Helicobacter pylori (H. pylori Bacteria in second part of stomach)
Type ____ gastritis is autoimmune related, whereas type ____ gastritis is caused by infectious diseases (e.g., H. pylori).
A; B
____ (Acute/Subacute/Chronic) gastritis carries an increased risk of gastric carcinoma.
Chronic
Chronic gastritis carries an increased risk of what kind of gastric carcinoma(s)?
Mucosa-associated lymphoid tissue (MALT) lymphoma and gastric adenocarcinoma
A patient on chronic NSAID therapy complains of stomach pain and is found to be anemic. What is the pathophysiology of his condition?
NSAIDs reduce prostaglandin E2, causing erosive gastritis (this is erosive gastritis), which causes occult blood loss and mild anemia
By what mechanism do severe burns cause acute gastritis?
Curling ulcers are caused by a decrease in plasma volume, leading to a sloughing of gastric mucosa
How can brain injury cause acute gastritis?
Cushing ulcers are caused by increased vagal stimulation, which increases acetylcholine and, in turn, acid production by parietal cells
A woman with Graves disease is anemic with a high MCV despite taking iron. She has bad abdominal pain. What part of her stomach is affected?
Fundus/body (this is chronic type A gastritis of the stomach, with pernicious anemia, associated with other autoimmunity such as Graves)
In acute gastritis, there is disruption of what type of barrier?
Disruption of mucosal barrier
What type of gastritis is an alcoholic most at risk for?
Acute gastritis
A patient with rheumatoid arthritis, adherent to his medications, has nausea and abdominal pain. What type of gastritis are you considering?
Acute gastritis (the patient is likely taking NSAIDs daily)
