Q

chronic gastritis

A

presence of chronic mucosal inflammatory changes
-atrophy and metaplasia

majority - h. pylori infection

autoimmune - pernicious anemia - < 10%

also with drugs, alcoholi, toxins

Q

swallow urea with carbon-14 tag - do breath test

A

if positive - h. pylori

-takes up C-14 and CO2 given off has this tagged carbon

Q

tx h pylori

A

PPIs and antibiotics

22
Q

h pylori diagnosis

A

detection of organism in biopsy

often in antrum

23
Q

autoimmune gastritis

A

spares antrum

  • includes hypergastrinemia - achlorydia
  • defective gastric acid secretion

aka atrophic

24
Q

autoimmune gastritis path

A

Abs to parietal cells and IF - detected in serum and gastric secretions

CD4 T cells against parietal cell components** - H/K ATPase

chief cells also get destroyed

25
pernicious anemia
with autoimmune gastritis if severe
26
oxyntic mucosa
acid producing
27
autoimmune gastritis histo
glandular atrophy and inflammatory infiltrates destroys acid producing mucosa in body nd fundus may see intestinal metaplasia
28
autoimmune gastritis
60yo female often with other autoimmune disease - hashimotos, DM, addison, graves, etc.
29
atrophic glossitis
smooth beefy tongue | -with B12 deficiency
30
reactive gastropathy
chemical injury NSAID use bile reflux trauma
31
eosinophilic gastritis
allergy, parasites, h. pylori
32
lymphocytic gastritic
celiac
33
granulomatous gastritis
crohn, mycobacteria, fungi, CMV, h. pylori
34
trichobezoar
hair ball in stomach
35
peptic ulcer
chronic solitary lesions in part of GI tract exposed to lots of acid usually with chronic gastritis - association with h. pylori and NSAID use
36
ulcer
by definition through the muscularis mucosa
37
erosion
limited to mucosa
38
PUD clinical
duodenal, male, h. pylori related also esophagus with GERD or meckel diverticulum with gastric mucosa pretty common
39
zollinger ellison syndrome
uncontrolled release of gastrin by tumor get lots of acid - can cause ulcers
40
hypercalcemia
stimulate gastrin production and increased acid secretion
41
classic peptic ulcer
sharply punched out defect heaped up margins - in cancer
42
pneumoperitoneum
air within abdominal cavity
43
tx of PUD
antibiotics - h pylori PPI surgery if severe bleeding/perforation
44
melena
black tarry stools stool in contact with acid - in upper GI bleeds
45
hematochezia
bright red blood in stool | -lower GI bleed
46
coffee grounds
slow bleeding/oozing
47
red blood/clots
active ongoing bleeding
48
bile stained
no bleeding above treitz ligament
49
clear
competent pylorus - but bleeding could still be occuring
50
confirmation of bleeding location
upper GI endoscopy - EGD - diagnostic and therapeutic - inject epi or electro coag techniques can biopsy with EGD - determine h. pylori infection
