A pancreatic fistula is defined as the leakage of pancreatic fluid into another organ or compartment because of pancreatic duct disruption or pseudocyst formation. It is most often seen in middle-aged men between 40 and 50, particularly in patients who have a history of chronic alcoholism and pancreatitis. The tract may fistulae into the pleura, creating a pancreaticopleural fistula, an exceedingly rare condition presenting as a recurrent pleural effusion and extremely high amylase levels, a key distinguishing factor in diagnosis.

- Social behavior declines in aging, particularly noted in old female rats, prompting research into how their brain responds to social interactions.
- The study measured mRNA activation in young and old female rats after brief exposure to a novel rat, finding significant differences in neural response, particularly in the lateral septum and septohypothalamic area, with young rats exhibiting greater responses.
- Additionally, relative oxytocin receptor expression was assessed, revealing that age-related declines in social investigative behavior are linked to specific brain regions, especially with a noted decrease in the ventromedial hypothalamus.
Gastrointestinal stromal tumors (GISTs) are rare in young individuals and typically affect older adults. We present the case of a previously healthy male who presented with severe hematochezia, fatigue, and dizziness. Colonoscopy did not demonstrate any colonic mass.

Materials And Methods: In this single-center, prospective trial, consecutive patients with NSCLC referred for a PET study between May 2017 and June 2018 were enrolled. All patients received contrast-enhanced imaging on a clinical PET/DECT system.
