You may be interested in the book The Keystone Approach by Rebecca Fett. It goes over research into the connection between pediatric strep throat and psoriasis. IIRC(from the book), if you are diagnosed with psoriasis before the age of 40, there is a 90% chance that it happened shortly after a... bad case of strep throat? Tonsillectomy? I forget which. Pretty eye opening book with some good diet-based advice on reducing symptoms of psoriasis, if you are looking for relief.
