I watched with quite a lump in my throat (disclaimer - massive pregnancy hormones may have contributed). The circumcised man and the woman with psorhoisis (sp?) in particular. It's awful that people have put up with conditions that effect their quality of life so much, and so lovely when something can be done.
DH and I were debating why people would go on the show, but we concluded that the people were referred very quickly to the best specialists possible, so it was better than going to the GP and getting normal NHS care.
