Q

How is Barret’s esophagus Dxed?

A
  • Two criteria must be fulfilled to make a diagnosis of Barrett’s esophagus:
    • Endoscopist must document that columnar epithelium lines the distal esophagus.
    • Histologic exam of biopsy specimens from columnar epithelium must reveal specialized intestinal metaplasia.

Q

Causes of PUD

A

  • cytotoxins
  • etoh

  • Peptic ulcers can present with any of 3 dyspeptic symptom patterns:
    • Ulcer-like or acid dyspepsia (burning pain; epigastric hunger-like pain; relief with food, antacids, and/or antisecretory agents)
    • Food-provoked dyspepsia or indigestion (postprandial epigastric discomfort and fullness, belching, early satiety, nausea, and occasional vomiting)
    • Reflux-like dyspepsia
42

Duodenal! 75%

43
Q

47
Q

How can a test for H. pylori be done?

A

stool antigen or urea breath test

48

  • ↓ calcium-glucose not available due to lack of insulin so body feeds off of fatty acids—calcium binds to fatty acids so is now ↓
  • ↑ C-reactive protein (CRP)
  • ↑hematocrit from hemoconcentration due 3rd spacing (from inflammatory rxn)
  • ↑ blood urea nitrogen (BUN) from dehydration/3rd spacing
80

89
Q

complications of diverticulitis

A

bowel obstruction, development of an abscess, fistula, or a colonic perforation into the peritoneum and peritonitis.

90
Q

How is acute diverticulitis Dxed?

A

abdominal CT scan with oral and IV contrast to establish the diagnosis of acute diverticulitis because it has a high sensitivity and specificity for acute diverticulitis and it can exclude other causes of abdominal pain.

91
Q

Tx of acute diverticulitis

A

in absence of complications, the treatment is antibiotics that cover bowel flora (e.g., a fluoroquinolone plus metronidazole) and bowel rest (i.e., no oral intake). Surgery is needed for perforation or abscess.
