| signs and symptoms of an annular pancreas? | asymptomatic but may require surgery later |
| etiology is gall stones, alcohol, mumps | acute pancreatitis |
| pancreas releases its lytic enzymes causing necrosis of its own tissue and surrounding tissue | acute pancreatitis |
| patient presents with sudden onset of severe boring abdominal pain that radiates to the back, nausea and vomiting | acute pancreatitis |
| what two signs with patients with acute pancreatitis present with? | cullen's sign, turner's sign- serum amylase is greatly elevated |
| half of patients who survive acute pancreatitis are at risk of developing what? | pancreatis pseudo-cyst |
| how are pancreatic psuedo-cysts found? | CT |
| these contain degraded blood, debris of necrotic tissue, and fluid rich in pancreatic enzyme | pancreatic pseudo-cyst |
| pancreatic pseudo-cysts have the potential to do what? | enlarge and obstruct the duodenum |
| progressive destruction of pancreatic parenchyma with irregular fibrosis and chronic inflammation | chronic pancreatitis |
| the etiology of this disease is alcohol, obstruction of the pancreatic tissue, pangreatic injury, cystic fibrosis, or could be idiopathic | chronic pancreatitis |
| patient presents with recurrent or persistent vague abdominal pain or decreased pancreatic exocrine/endocring secretion | chronic pancreatitis |
| hereditary; thick secretion of exocrine pancreas and respiratory system | cystic fibrosis/mucovicidosis |
| what is the most common type of pancreatic adenocarcinoma? | ductal adenocarcinoma |
| what are predisposing factors for pancreatic cancer? | smoking, BMI and dietary factors, DM, chronic pancreatitis |
| where is pancreatic cancer most commonly found? | head of the pancreas |
| patient presents with anorexia, weight loss, gnawing pain in the epigastrium radiating to the back and jaundice 50% of the time | pancreatic adenocarcinoma |

| pancreatic adenocarcinoma causes what? | intractable pain, cachezia and death |
| are CA-19-9 serum levels increased or decreased in pancreatic adenocarcinoma? | increased |
| lab findings for pancreatic adenocarcinoma include | increased CA-19-9 serum levels |

| this is associated with MEN1 | insuliomas |
| lab findings for insuliomas? | increased serum insulin, decreased glycemia |
| patient presents with sweating, nervousness, hunger confusion, lethargy and coma | insuliomas |
| how are symptoms relieved when a patient presents with insulioma? | eating |

| severe peptic ulceration of duodenum/jejunum associated with MEN1 | Pancreatic gastrinoma/Zollinger ellison's syndrome |
| are glucagonomas (alpha cell tumors) usually benign or malignant? | malignant |
| Risk factors include mild diabetes, necrotizing migratory rash, anemia, venous thrombosis and severe infection | glucagonoma (alpha cell tumor) |
| Lab findings for glucagonomas? | 30x increase in serum glucagon |
