TREATMENT WITH NEOARSPHENAMINE
In May 1939 at the meeting of the American Medical Association in St. Louis I reported, in collaboration with Commissioner Rice, the course of a group of 86 patients with primary or early secondary syphilis who received, by means of the intravenous drip, 4 Gm. of neoarsphenamine over a period of five days. We are now able to report further observations that have been collected in the eleven months that have elapsed.
Patients Lost from Observation.—
We have been unable to establish contact with any of the 7 patients previously reported as having lapsed from follow-up observation. Two of these patients were never seen after they were discharged from the hospital; 3 made one visit to the follow-up clinic, and 1 made two visits. In massive dose chemotherapy the situation of the patients who allow treatment to lapse differs from that of those who allow routine treatment
