Hi Bruce and Dan.
These are definite references to Dupuytrens Contracture and KD.
Google: Orpha 481 and the summary is halfway down the page.

Google: Pubmed 2633568 Click on the top result and it will take you straight to the reference.
The second reference on pubmed is right below the first one.

As I said before I hope Im not wasting your time but I did find it intriguing. I had Gynomastia in puberty. I had it surgically removed when I was 22. I also have chronic Dupuytrens Contracture in both hands. I started supporting my jaw to eat over ten years ago. I have tremors, severe cramps throughout my body and muscular atrophy which is worse on my left side. I sometimes choke on food and have had several attacks of Laryngospasm. I have breathing problems with cold air.I also have bad attacks of pain in the back of my neck and up over to my left eye. The pain is crippling during these attacks. My left testicle sometimes rapidpy draws upwards and disappears inside me The burning red patches I get are a mystery. Its not Allergy or skin disease.
