majority of pancreas is exocrine or endocrine portion
exocrine (80%)
most adenocarcinomas of pancreas arise from what
ducts-lining epithelium of exocrine portion
common sites to find ectopic pancreas
duodenum, meckel's diverticulum, stomach, jejunum
clinical features of severe acute pancreatitis
severe abdominal pain radiating to the back
shock
grey-turner spots
DIC
ARDS
lab findings for acute pancreatitis
increased serum/urine amylase
increased serum lipase
leukocytosis
decreases serum calcium
when does serum amylase return to normal after acute pancreatitis onset
within 3 days
*urine amylase and serum lipase stay elevated up to a week
what are two reasons for false positive acute pancreatitis using serum amylase
salivary gland disease (inflammation)
gut perforation
most specific test for acute pancreatitis
serum lipase
4 factors that determine adverse survival of acute pancreatitis
leukocytosis > 16,000 uL
hyperglycemia > 200 mg/dL
fall in HCT > 10% within 48 hours
hypocalcemia < 8 mg/dL within 48 hours
type of necrosis seen in acute pancreatitis
enzymatic fat necrosis - calcium soaps
pathogenesis of acute pancreatitis
activated pancreatic enzymes digesting pancreatic tissue, trypsin activates other digestive enzymes and kallikrein system
predisposing factors for acute pancreatitis
biliary tract stones - most common
alcoholism
hypercalcemia
hypertriglyceridemia
most common cause of acute pancreatitis
biliary tract stone obstruction
caused by repeated episodes of MILD acute pancreatitis
chronic pancreatitis
associated with chronic pancreatitis
alcoholism
cystic fibrosis
result of exocrine/endocrine hypofunction of chornic pancreatitis
exocrine - malabsorption
endocrine - DM
pathologic changes seen in chronic pancreatitis
fibrosis
focal calcifications
pancreatic pseudocysts
class findings in chronic pancreatitis
pancreatic calcifications
steatorrhea
DM
No elevation of serum amylase or lipase
Is the serum amylase or lipase elevated in chronic pancreatitis
NO
most common location of pancreatic adenocarcinoma
head of pancrease (2/3)
associated with painless jaundice
adenocarcinoma of the head of the pancreas
associated with pain, distant metastases and abdominal pain
adenocarcinoma of body and tail of pancreas

adenocarcinoma of pancreas
most common sites affected by CF
pancreas, tracheal, and bronchial glands
genetics of CF
autosomal recessive gene on 7q31
most common mutation in CF
delta F508 deletion
associated with pneumonia (staphylococcus and Pseudomonas) and bronchiectasis
CF
what is affected first in CF, exocrine or endocrine function
exocrine function - malabsorption
endocrine function is preserved until late in disease
diagnostic test for CF
abnormally high levels of Cl and Na in sweat
responsible for most morbidity and mortality in CF
recurrent and chronic respiratory infections
Can CF lead to cirrhosis
Yes - portal HTN with ascites, splenomegaly, and esophageal varices
99% of men are infertile
