Abstract
A total of 351 circulating eosinophil counts were done on 75 children. The range of circulating eosinophils for 18 normal children was 109 to 359. In 12 patients with nonfebrile miscellaneous diseases the circulating eosinophil counts ranged from 84 to 599, and in three patients with mild febrile illnesses, from 170 to 341. A possible explanation for the fact that these counts fell within the normal range was discussed. In 29 patients with acute febrile illnesses the initial circulating eosinophil counts ranged from 0 to 97. Serial counts during convalescence on three of these patients are presented and the prognostic significance discussed. In 10 patients with various allergic manifestations there was a range of 393 to 2665. Serial counts on one case of acute atopic eczema treated with ACTH are presented. Serial counts on one patient before and after laparotomy are presented. Results of the "ACTH test," the "epinephrine test" and the "insulin test" on a group of children with miscellaneous diseases are presented.
