I do not know what this condition is, so I did a search. A lot of searches came up about this being a disease in swine, but I found a couple referring to humans. All I found is that it is a thinning of the nasal membrane which can cause a runny or stuffy nose, crusty nose and an odor. It can be caused by aging, menopause and infection. Another source said it can be caused by iron or vitamin A deficiency. The treatments appear to be antibiotic ointments and vitamins. Another site said the antibiotic Cipro, removal of the crust and nasal irrigation may help, although there is no known cure. This is probably not very helpful I know, but I thought I'd tell you what I found out. Do a search and see what you can find. Good luck!
