This looks interesting:
Don and Jill are church-planting missionaries in Germany. In August of 2000, Don was diagnosed by two teams of doctors at two university hospitals with new variant-Creuzfeldt-Jakob Disease (nvCJD), the human version of Mad Cow Disease. The Vanderhoofs were told by both hospitals that this disease is always fatal. However, God had other plans and healed Don of the disease. A book has been written detailing how God helped Don and Jill through Mad Cow Disease. The book is entitled From Strength to Strength, and is their testimony of God's grace, help, and healing from this terminal illness.
Its first printing of the book was in the English and German languages. The English version is now in its third-edition printing and contains pictures with letters from three different doctors.
