Background & Aims Organized screening programs reduce colorectal cancer (CRC) related mortality. Multi-target stool DNA (MT-sDNA) test is an FDA approved screening modality with good compliance and follow-up. In cases of positive MT-sDNA test and negative colonoscopy, experts recommend a 10-year follow-up interval. Concern for interval CRC has led...

Amyloidosis encompasses several diseases associated with deposition of low-molecular-weight proteins in an abnormal configuration. In light-chain amyloidosis (AL), monoclonal free lambda (λ) or kappa (κ) light chains are the amyloid proteins involved and can deposit in almost any organ. Symptoms vary depending on presence and extent of organ involv...
