Extreme Case of Excema...

My 1 year old niece was diagnosed with Excema when she was about 3-4 months old, she has been prescribed Excema creams, bath wash, etc and nothing seems to work. They live in Denver, CO and the weather there is very dry, which seems to aggravate her Excema, her skin is so dry that it's not cracking and a milky-brownish fluid is coming out of the skin around her ankles. She has red blotches on her upper thighs, back of both knees, arms and back, and scratches constantly when those areas are not covered by clothing. My brother and sister-in-law have been to dermatologists, her pediatrician and now the Children's Hospital in Denver. The Dr. has prescribed another cream to try and has advised that her condition could worsen with the coming winter. They are hopeful that the Excema will lighten up as she gets older, but for the time being it's horrible and she seems to be itching all the time. The Dr at Children's Hospital recommend wetting a onesie and wringing out water so the onesie is damp then putting her new lotion on and the onesie over it, then putting another layer of dry clothing over the wet onesie, this should keep her skin nice and moist, the problem is that with living in Denver, CO they can only do this during the warm months.

Does anyone have any recommendations as to what they can try to cure or help with the Excema?

Does anyone have any knowledge on Egyptian Magic cream for skin?
