Description: Gastroenteritis is defined as vomiting or diarrhea due to inflammation of the small or large bowel, often due to infection. The changes in the small bowel are typically noninflammatory, while the ones in the large bowel are inflammatory. The number of pathogens required to cause an infection varies from as few as one (for Cryptosporidium) to as many as 10 8 (for Vibrio cholerae).
Description: This special issue of Gastroenterology is devoted to the recent advances and future challenges of colorectal cancer. The overall incidence of colorectal cancer is decreasing in many countries; however, there is an alarming increase among young adults. Moreover, racial, ethnic and geographic disparities in mortality from colorectal cancer persist despite screening efforts.

While usually not life threatening, gastro can be a debilitating and unpleasant experience for patients and their carers, particularly when they don’t fully understand why they are suddenly sick.
