Cronkhite-Canada syndrome is an extremely rare condition of gastrointestinal polyposis in which the main presenting features are diarrhoea and dysgeusia. The polyps in this condition are characteristically distributed throughout the entire gastrointestinal tract except the oesophagus, and these patients exhibit unique ectodermal abnormalities. Herein, we report a 50-year-old male who had recurr...

In 2009 we reported the fatal case of a toddler who had received codeine after adenotonsillectomy for obstructive sleep apnea syndrome. The child was an ultra-rapid metabolizer of cytochrome P4502D6 (CYP2D6). We now report 3 additional fatal or life-threatening cases from North America. In the 2 fatal cases, functional gene duplications encoding for CYP2D6 caused a significantly greater product...

The syndrome occurs predominantly in male, with a ratio of three males to two females. Because of the rarity of the syndrome, there are no evidence-based therapies and the treatments described include a combin...
