Study Notes
Gastrointestinal Tract
- A 15-year-old man with abdominal pain and bloody diarrhea for 6 months is likely to have Crohn's disease, characterized by mucosal architectural alteration, chronic inflammation, deep lymphoid aggregates, and deep fissures extending into the muscularis propria, with multiple granulomas identified within the lamina propria.
- The disease is not exclusively limited to the colon, can involve other parts of the gastrointestinal tract, and is associated with perinuclear antineutrophil cytoplasmic antibody (P-ANCA).
- Complications of the disease include toxic megacolon, and it can cause malabsorption of nutrients affecting growth and development.
Urinary Tract Infections
- A 55-year-old woman with fever and right-sided flank pain is likely to have a urinary tract infection, with a radiopaque calculus that forms a cast of a dilated right renal collecting system.
- The presence of magnesium ammonium phosphate crystals in the urine is suggestive of a urinary tract infection, with Proteus vulgaris as the likely causative organism.
Acid-Base Balance
- A baby with irritability, difficulty breastfeeding, and diarrhea may have an underlying acid-base imbalance, with elevated respiratory rate and ABG results showing pH 7.39, PaCO2 = 27 mmHg, and HCO3 = 19 mEq/L, indicating partial compensation for metabolic acidosis.
Gastrointestinal Disorders
- A 29-year-old female with weight loss, fatigue, and diarrhea is likely to have celiac disease, characterized by villus shortening and intraepithelial lymphocytosis on duodenal biopsy, and responds to a gluten-free diet that excludes wheat and rye.
Gastric Ulcers
- A 43-year-old man with mid-epigastric pain and nausea is likely to have a gastric ulcer, with a solitary sharply demarcated 2-cm shallow gastric antral ulcer on upper GI endoscopy.
- The presence of Helicobacter pylori, as detected by a positive urea breath test, is a likely contributing factor to the development of the ulcer.
Gallstones
- Black pigment gallstones are associated with hereditary spherocytosis, obesity, pregnancy, bile infection, and hyperlipidemia.
Complications of Cirrhosis
- Complications of cirrhosis include ascites, hepatic encephalopathy, coagulopathies (bleeding disorders), and perianal/rectal varices.
Liver Function
- A 31-year-old man with scleral icterus but no abdominal pain or fever is likely to have a liver function disorder, with a possible diagnosis of viral hepatitis.

Gastrointestinal Pathophysiology
- A 15-year-old man with abdominal pain and bloody diarrhea for 6 months has colon biopsy showing mucosal architectural alteration, chronic inflammation, deep lymphoid aggregates, and deep fissures extending into the muscularis propria, and multiple granulomas in the lamina propria.
- The disease is not exclusively involving the colon, can involve other parts of the gastrointestinal tract.
- Most patients are positive for perinuclear antineutrophil cytoplasmic antibody (P-ANCA).
- The disease can cause complications such as toxic megacolon and malabsorption of nutrients affecting growth and development.
Urinary Tract Infection
- A 55-year-old woman with fever and right-sided flank pain has a urinalysis revealing normal specific gravity, pH 7.5, and many WBCs and WBC casts.
- Abdominal radiograph reveals a radiopaque calculus that forms a cast of a dilated right renal collecting system.
- Urine culture grows Proteus vulgaris, which can form magnesium ammonium phosphate crystals.
Acid-Base Balance
- A baby with irritability, difficulty breastfeeding, and diarrhea has an ABG result showing pH 7.39, PaCO2 = 27 mmHg, and HCO3 = 19 mEq/L, indicating metabolic acidosis, partially compensated.
Celiac Disease
- A 29-year-old female with weight loss, fatigue, and diarrhea has a duodenal biopsy showing villus shortening and intraepithelial lymphocytosis.
- The patient is put on a special diet excluding wheat and rye, and shows significant improvement.
Peptic Ulcer Disease
- A 43-year-old man with mid epigastric pain and nausea has a gastric antral ulcer on upper GI endoscopy.
- The patient is likely to have a positive urea breath test, indicating H. pylori infection.
Gallstone Risks
- Risk factors for black pigment gallstones include hereditary spherocytosis, but not obesity, pregnancy, bile infection, or hyperlipidemia.
