“We feel warranted in classifying a small percentage of these 26 cases under the heading of “prompt cures.” By this we mean that after two or three applications of X-rays, covering a period of six days, the spasms and whoops entirely disappeared and the patients were clinically well, except for, possibly, a very slight cough. “The bulk of the cases, however, we have classified as relieved. This group consists of perhaps 70 percent of the total. By relieved we mean that there has been a gradual diminution in the number of spasms. “There is a small percentage of cases, perhaps 10 to 15 percent, which apparently were not relieved. In this group are included one moribund case and one rather difficult feeding case. “While our evidence so far is not sufficient to warrant any definite conclusions, we have the feeling that the X-ray at the present time may be of more value in the treatment of pertussis than any other form of treatment, including serum.” X-RAYS FOR MALARIA An Italian physician, Dr. Antonio Pais, of Venice, has since 1916 been successfully treating malaria by means of X-rays. This treatment is, however, not employed as a substitute for quinine, but merely to reinforce its action. The X-rays are directed toward the region of the spleen, and the effect is to reduce its enlargement. At the same time the composition of the blood is modified. The success obtained by Dr. Pais has, according to the _Bibliothèque Universelle et Révue Suisse_ (Lausanne), been so great that the Italian Government decided to introduce his method of treatment into the military hospitals. Since the war the treatment has been studied by Prof. B. Grassi, who made a report, at an Italian scientific meeting, in which he declared the action of X-rays upon chronic malaria to be “truly marvelous.” The _Bibliothèque Universelle_ says, regarding earlier treatments: “The attempt was made by them to destroy the parasite contained in the spleen. But it is now known that the X-rays employed for therapeutic action have no effect upon micro-organisms, although they may be injurious to the elements of the blood. In the method devised by Dr. Pais, the X-rays are employed to stimulate the functioning of the spleen, of the marrow, and of the lympathic elements by means of slight but prolonged excitation; they are employed in infinitesimal doses—homeopathically, so to speak. Thus the result is absolutely different as well as the method.”
