B. Hartzell, on "The Nature and Causes of Eczema" in The Journal, Nov. 28, 1908, one can not fail to observe with surprise that only one physician, Dr. Henry C. Baum, Syracuse, in discussing the causes referred to hyperacidity as an internal cause. I have seen many cases of eczema, not due to occupation, local irritation or poisoning through dyestuffs, and in which it seemed reasonable to look for other causes-internal causes, such as the ingestion of acid fruits, e. g., plums, lemons or tomatoes. I have seen several patients who developed acute and extensive eruptions, after eating these acid fruits, and in whom the prompt use of sodium bicarbonate, or salicylate in full doses, internally, rapidly relieved the symptoms. Many cases of eczema may be classed with rheumatism, neuralgia and urticaria, as diseases due to uric acidemia, or hyperacidity SN - 0002-9955 M3 - doi: 10.1001/jama.1909.02540390045014 UR - http://dx.doi.org/10.1001/jama.1909.02540390045014 ER -
