[Frequent and rare forms of vitamin B 12 and folic acid deficiency anemias].
The common and rarer causes of vitamin B12 and folic acid deficiency are discussed with special reference to pathophysiological aspects and conditions in Switzerland. The overall incidence of Addisonian pernicious anemia was found to be 80 per 100,000 patients, whereas the incidence of other B12 deficiency states was 18 per 100,000  patients. Folic acid deficiency was found in 23 of 100,000 patients, though this figure appears to be an underestimate. Nutritional (latent) folate deficiency seems to be the most frequent vitamin deficiency in Switzerland.
