Abstract:
This is a case of an older man with no prior history of diabetes presenting with a combination of diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) in the setting of new-onset diabetes mellitus. His further work-up revealed intraductal papillary mucinous neoplasm (IPMN) on pancreatic imaging. Though his diabetes etiology could be multifactorial, it is possible that it is an initial presentation of IPMN. Data have been suggestive of diabetes mellitus associated with degree of dysplasia and worse prognosis of IPMN but the exact pathophysiology behind this is unknown, and it is unclear whether diabetes mellitus is an early presentation of IPMN. We discuss possible differential diagnoses needed to evaluate patients for possible triggers behind DKA and etiologies behind new-onset diabetes mellitus when indicated.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
