[Name] Polaris extremis [Source] Hogans Heroes Episode: Up In Klink's Room [Symptoms] 
A rare disease found only among Eskimoes. Symptoms are pains in nerve endings in fevers, craving for greens in the diet, and articular motary vascular spasms. Hogan faked contracting the disease in order to gain entry into a Nazi hospital operated by Doctor Ernst Klaus, a specialist in Eskimo diseases, so that he could obtain information on Kriegsmarine battle plans from a deep-cover agent.
