Various laboratory markers of inflammation are utilized in general practice, but their clinical diagnostic significance is often ambiguous. In the present study, we determined the clinical significance of the examination of serum levels of procalcitonin (PCT) by comparing the PCT levels with the levels of other inflammatory markers, based on a retrospective review of 332 PCT-positive patients, including cases of bacterial infection (20.5%), non-specific inflammation (20.8%), neoplasm (9.9%), con...

Immune checkpoint inhibitors (ICIs) such as nivolumab and ipilimumab are emerging agents for the treatment of cancers including melanoma. ICIs are known to cause immune-related adverse events (irAEs), including the development of enterocolitis, dermatitis, and nephritis. However, ICI-induced pancreatitis has seldom been reported, and its pathophysiology and clinical importance remain largely unknown. We describe a 76-year-old man with melanoma who developed acute pancreatitis without abdominal p...
