Flashcards in Gastric, Intestinal, and Pancreatic Function (PART 3) Deck (10):
1

Most common cause of chronic pancreatitis

Alcoholism

2

Two indirect tests used to diagnose this condition

Measure fecal chymotrypsin and fecal elastase-1

3

Specific diagnostic usefulness of the measurement of elastase-1

Secreted in any inflammatory state; sensitive and specific marker of chronic pancreatitis

4

Specific diagnostic usefulness of the measurement of trypsin

Highly sensitive indicator of pancreatic disease; recommended as screening test for CF in 5-day-old infants

5

conditions which may lead to the malabsorption syndrome

*Pancreatic insufficiency
- celiac disease
- resection of ilium
- parasitic infection of the gut
(others on slide 159)

6

Why do patients with malabsorption syndrome have steatorrhea, weight loss, vit deficiencies, anemia, edema, coag disorders and osteomalcia

Deficiencies of fat and water soluble vitamins

7

Four tests used to evaluate the malabsorption syndrome

1. Carotene
2. Microscopic examination of stool for fat
3. D-xylose absorption test
4. Breath hydrogen test

8

Principle and specific area of the GI tract assessed via the D-xylose absorption test

Assesses the functional integrity of the small intestine

9

List the specific diagnostic usefulness of the breath hydrogen test

Assesses whether malabsoption is caused by bacterial overgrowth or a lactase deficiency

10

Describe the multiple endocrine neoplasia (MEN) syndrome

Occurrence of tumors involving two or more endocrine glands within a single patient
- Two types: MEN 1 (Wermer's Syndrome); MEN 2 (Sipple's Syndrome)
