Pirates right fielder Xavier Nady, hospitalized earlier in the week for intestinal inflammation, will be examined Monday to determine if he has a chronic condition. Nady said yesterday that, upon doctors' request for information about his family background, it was found that a cousin has Crohn's disease, a lifelong condition that can cause excruciating pain in the digestive area, as well as weight loss and other disruptions. Genetics increase the risk of having the condition.
