In our experience as well as that of Lewis and associates1 roentgen irradiation for the epilation of scalp hair has been found to be the most effective adjunct method in the treatment of tinea capitis.
Occasionally, however, untoward reactions may occur even with as little as 350 to 400 r, principally in the form of itching and few to numerous small pustules.
When a larger dose is administered, dermatitis usually results. MacKee and associates2 stated that permanent damage to the scalp may result if more than twice the epilating dose is given.
The prevention of such a serious sequela in a patient to whom a technician gave 800 r to each of four areas seemed worth reporting. The patient was a white girl aged 6 who had received more than double the usual epilating dose, 6 milliamperes having been used instead of 3 and all other factors
