Rakesh Lattupalli just graduated from our fellowship in June. He was an exceptional fellow. He just finished a scientific article on the Melamine outbreak. Rakesh was the person who got me interested in the subject. The article is a nice overview of some of the scientific data on melamine toxicity.
Like me, he feels that melamine is not likely to be the entire story and a second co-factor will be identified that is critical to the development of nephrolithiasis. He suggests cyanuric acid as a possible candidate.
