Case Summary: An 83-year-old man with a history of CABG presented with an inferior ST-elevation myocardial infarction (STEMI).

Characteristics of recurrent in-stent restenosis after second- and third-generation drug-eluting stent implantation.

Background: In second- and third-generation drug-eluting stent (DES) era, in-stent restenosis (ISR) is not commonly seen. However, a few patients still need repeat revascularizations for recurrent ISR even after second- and third-generation DES implantation.

Methods: From January 2012 to March 2017, 2339 lesions underwent second- and third-generation DES (Nobori, Promus Element, Resolute Integrity, Xience, Ultimaster and Synergy) implantation, of which 95 lesions (4.

Small multicentric pancreatic carcinoma usefully diagnosed by positron emission tomography.

Pancreatic carcinoma has a poor prognosis, and early detection is essential for potentially curative resection. Despite a wide array of diagnostic tools, pre-operative detection of small pancreatic carcinomas is difficult. We report a case of pancreatic carcinoma that was bicentric and small.
