"A new study http://www.cmaj.ca/press/cmaj082068.pdf in CMAJ (Canadian Medical Association Journal) www.cmaj.ca suggests that air pollution may trigger appendicitis in adults.  The study, conducted by researchers at the University of Calgary, University of Toronto and Health Canada, looked at 5191 adults admitted to hospital in Calgary, Alberta, Canada. Fifty-two per cent of admissions occurred between April and September, the warmest months of the year in Canada during which people are more likely to be outside."
