What are common cuases of acute gastritis | Aspirin and NSAIDS, Alcohol, Acid and Alkali ingestion, Stress, Shock related mucosal ischemia, Sepsis |
How does ETOH contribute to Gastric erosions | Stimulates over secretion of HCL |
How does aspirin and other NSAIDS contribute to gastric erosions | inhibit local synthesis of prostaglandins weakening mucosal defense system |
How does shock contribute to gastric erosion | hypoprofusion results in increased susceptibility of mucosal cells to acid |
What type of gastric stress ulcer is caused by brain injury | Cushing ulcer |
What type of gastric stress ulcer is caused by burns | Curling ulcer |
What are the 3 main types of non erosive gastritis | Chronic Type A, Chronic Type B, hypertrophic gastritis |
What type of chronic gastritis is caused by autoimmune disease and has a higher risk of gastric adenocarcinoma | Chronic Type A gastritis |
What type of chronic gastritis is caused by H. Pylori and increases your chance of adenocarcinoma and lymphoma | Chronic Type B gastritis |
What happens in late stages of chronic type a and B gastritis | atrophy of gastric glands, intenstinal metaplasia, lymphocytic follicles in the mucosa |
What is the number one infectious cause of PUD in the duodenum and gastric types | H. Pylori |
How does H. Pylori cause PUD | induces an intense inflammatory and immune response causes mucosal injury |
Which type of ulcer is more common gastric or duodenal | Duodenal 4:1 over gastric ulcers |
Patient presests with PUD which doesn't respond to usual treatment what is the likely cause of their ulcers | zollinger-ellison syndrome a gastrin secreting tumor causing hyper acidity and ulceration |

Patient presents with s/sx of PUD you order an endoscopy and notice a small 1-2 cm diameter lesions with smooth sides and bottom. Borders are sharp what is the likely cause | Peptic Ulcer |
What is the most common complication from a peptic ulcer | hemorrhage- look for melena and iron deficiency anemia |
What other complications can arise from peptic ulcer disease besides hemorrhage | Perforation, Stenosis and obstruction, penetration into pancrease |
What is the most common malignancy of the stomach and what is the 5 yr survival rate | Adenocarcinoma- 5yr survival rate is 20% |
Where is the most likely place to find gastric cancer | Pylorus and pyloric antrum |
Patient is 30yrs old and presents complaining of s/sx of PUD based on what you know about PUD where is there ulcer most likely located | Duodenal Ulcer- they are the most common and occur 25-75yrs. Gastric ulcers occur 55-65 yrs |

Patient complains of gnawing dull aching hunger like pain in epigastric area that is relieved by eating what is likely causing their symptoms be specific include location | PUD in duodenal area pain can be relieved by eating and antacids. Gastric ulcers typically not relieved by food. |
You are working up a patient for PUD and why would you order a UGI (upper gastroinetsinal contrast series) over a endoscopy | Is is less invasive, expensive and is 90% accurate when using double contrast. Endoscopy is invasive and expensive but more accurate |
What tests could you order to confirm PUD caused by H. Pylori | Urea Breath test, Stool antigen test, specific antibody test or endoscopic bx |
What treatments will you order for PUD | H2 blockers, PPI and if it is caused by H. Pylori add 2 antibiotics may need to step it up to quadruple therapy |
