Random Flashcards
scleroderma
esophageal smc atrophy/fibrosis
- low LES pressure
- low/absent peristaltic ativ in esophageal body
- abnml LES relaxation w/ swallowing
solids only + chronic heartburn –> progressive sx –>
peptic stricture
solids and liquids + chronic heartburn –> progressive sx –>
scleroderma
adjust these meds for renal insufficiency
histamine antagonists
chronic gastritis
H. pylori + isolated in antrum
pH will be
low
H. pylori colonizes G cells –> hyperplasia –> inc gastrin –> inc acid –> dec pH
in acute pancreatitis, hypo_____ is a poor prognostic marker
hypOcalcemia
suggests inc Ca flux into tissues, binding up peripancreatic fat
temporary blockage of the exit of enzyme granules from acinar cells
Acute pancreatitis due to biliary sludge (early stones)
osmotic diarrhea osmotic gap is
> 125
which extra intestinal sx of UC is most likely to parallel disease course
peripheral arthritis
thickened gallbladder wall
cholecystitis
Effect of removing the gallbladder on lithogenic bile
Bile remains just as lithogenic after the gallbladder is removed
brown pigment stones
stasis of bile and anaerobic bacterial infection within the biliary tree
Most common site of gut carcinoids
terminal ileum
carb absorption
absorbed in the proximal small intestine by a sodium-dependent carrier mechanism
main stimulus for secretin stimulation
ACID
Secretin is released from intestinal mucosa into the splanchnic circulation when a higher acid load enters into the duodenum. This leads to increased bicarbonate secretion from the pancreas to help neutralize the acid and allow pancreatic enzymes (which require a more alkaline pH) to function.
high LFTS >1000, negative viral hepatitis labs
acetaminophen OD
secondary hemochromatosis
iron accumulation in kuppfer cells (macrophages)
Sessile serrated adenomatous polyps
likely location
R colon
tubular adenomas
tubulovillous
villous
sessile or pedunculated
likely location
L colon
Cancers presenting with iron deficiency anemia and the lack of overt rectal bleeding
likely location
R colon
Cancers presenting with blood
likely location
L colon
Although the other disorders can cause intussusception, a ________ would be more common cause in this 4 y/o age group.
meckel’s diverticulum
Air in the intestines is pneumatosis intestinalis and associated with ____________.
necrotizing enter colitis
currant jelly stool
intussusception
Omphalocele is always a defect in the
umbilical ring
Gastroschisis is a defect lateral to the
umbilicus
________(drug) has been shown to increase lower esophageal sphincter pressure
Metoclopramide
cystic fibrosis
chronic pancreatitis
hereditary hemochromatosis triad of sx
cirrhosis
diabetes
skin pigment (Fe+melanin=bronze)
small testes
hereditary hemochromatosis
