2. Name 3 categories (and examples) of etiologies of chronic gastritis.

Explanation

Chronic gastritis can have various causes, including chronic infection, autoimmune conditions, and toxic substances like alcohol and smoking. While genetic factors can play a role in some cases, dietary choices and psychological factors are less commonly associated with chronic gastritis.

Submit
3. What is the organism seen here?

Explanation

The correct organism depicted in the image is Helicobacter pylori, commonly known as H. pylori. It is a type of bacteria that infects the stomach lining and is a common cause of peptic ulcers and gastritis.

Submit
4. Which of the following conditions are associated with H. pylori?

Explanation

H. pylori is a bacterium that is known to cause chronic gastritis, gastric ulcers, duodenal ulcers, MALT lymphoma, and adenocarcinoma. It is not associated with irritable bowel syndrome, pancreatitis, or hyperthyroidism.

Submit
5. What are the two 1st line drugs to treat H. pylori? Which is preferred when resistance is not a factor? What is second line?

Explanation

When treating H. pylori infections, it is important to know the first line and second line treatment options. The correct first line drugs are clarithromycin and metronidazole, with clarithromycin being the preferred option unless resistance is above 15%. If resistance to clarithromycin is present, then metronidazole should be used. The second line drug will typically be the one of the first line drugs that has not been used yet, to avoid further resistance development.

Submit
6. What is the medical term for inflammation of the stomach lining?

Explanation

Chronic gastritis is a condition characterized by inflammation of the stomach lining, which can lead to stomach pain, nausea, and digestive issues. Acid reflux is a condition where stomach acid flows back into the esophagus, causing heartburn. Appendicitis is inflammation of the appendix, a small pouch attached to the large intestine. Gallstones are solid particles that form in the gallbladder, causing pain and other symptoms.

Submit
7. Which cells and regions of the stomach are affected in autoimmune chronic gastritis?

Explanation

Autoimmune chronic gastritis primarily affects parietal cells in the body and fundus of the stomach. Parietal cells are responsible for producing stomach acid, and their destruction can lead to decreased acid production and subsequent health issues.

Submit
8. What are at least 3 differences in environmental chronic gastritis compared to autoimmune gastritis?

Explanation

Environmental chronic gastritis and autoimmune gastritis have distinct differences in their impact on the stomach lining, hormone levels, and associations with specific antibodies or conditions.

Submit
9. What is the difference between reactive gastropathy and gastritis?

Explanation

While both reactive gastropathy and gastritis can have similar causes, the key difference lies in the presence of hemorrhage without significant inflammation in reactive gastropathy, as opposed to gastritis which is characterized by both hemorrhage and inflammation.

Submit
10. What is a peptic ulcer?

Explanation

Peptic ulcers are commonly caused by the bacteria H. pylori and/or the chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs). The erosion of the protective lining in the stomach or duodenum can lead to the formation of an ulcer.

Submit
11. Which blood type is associated with an increased risk of H. pylori infections and resultant diseases?

Explanation

Individuals with blood type O have been found to be more susceptible to H. pylori infections and the development of related diseases compared to individuals with other blood types. This is due to certain factors present in blood type O that make them easier targets for H. pylori bacteria.

Submit
12. What can be seen in the center of the image just above the forceps?

Explanation

The correct diagnosis is a penetrating acute duodenal ulcer, which is characterized by erosion through the wall of the duodenum. Gastric polyps, pancreatic pseudocysts, and esophageal varices are unrelated conditions that would not present in the given location.

Submit
13. What is the primary cause of Zollinger-Ellison syndrome?

Explanation

Zollinger-Ellison syndrome is primarily caused by the presence of pancreatic or duodenal tumor which leads to hypergastrinemia and excessive acid production, resulting in multiple ulcers that are difficult to treat.

Submit
14. What are the most common sites of peptic ulcers?

Explanation

Peptic ulcers most commonly occur in the duodenum, stomach (antrum), and GE junction. The incorrect answers do not represent common sites for peptic ulcers.
