subject has lost weight, fever in the afternoons, general weakness, loss of apetite (even though he is trying to feed himself well) and intolerable general malaise, sometimes he feels somewhat dizzy. Every test, chest x-rays , endoscopic study of the pancreas, infectious disease's studies, cultures of blood and urine, nuclear medicine scanner etc.. every thing come up normal, except for a slight anemia and a small stone in the choledocho (found during the endoscopy) All this has been going on from about two or more months now. Subject is 85 years old and is getting desperate. Could you help please ? Thank You.
