Core Tip

Core tip: We read with great interest the excellent review by Wong et al on extra intestinal manifestations of Helicobacter pylori (H. pylori) infection published in the journal. This is a well-documented and structured review. However, I believe that Wong et al failed to report the relationship between H. pylori infection and cobalamin.
