The value of the roentgen ray in acute cervical adenitis is questioned by many. Curiously, those least acquainted with the procedure are the ones most doubtful of its efficacy. This situation is probably due to the association of the use of roentgen rays with the treatment of malignant and allied diseases, in which failures are apt to be common, to the paucity of references to this subject in the American literature and, finally, to the innate fear of members of the medical profession of the employment of irradiation in any malady less morbid than a malignant process. It is the purpose of this paper to report results with this form of therapy in acute cervical adenitis, in the hope, thereby, of encouraging other workers to record their experiences. Proper evaluation of this mode of treatment will then be possible.Many practitioners are of the opinion that in the management of a patient with acute cervical adenitis no treatment is as good as any. The frequent failures with the present types of treatment account for this laissez-faire attitude. It is well known (Griffith and Mitchell,1 Boil¬ ing2) that cervical adenitis in childhood frequently terminates in sup¬ puration. In reporting 109 cases of acute adenitis, 96 of which were cervical, Holt and Howland 3 stated that 62 per cent of them ended with abscess. Local applications of heat or cold, or of ointments, have apparently no influence in preventing this outcome, or in shortening the duration of the illness. Ultraviolet therapy has been used with doubtful success. The employment of tonsillectomy, also recommended,4 seems illogical, for by the time a child is subjected to this radical procedure the tonsils and adenoids may no longer be a factor in the etiology. Furthermore, the many instances of acute cervical adenitis in tonsillectomized children are proof that the tonsils and adenoids are not always the offenders. Granted that these tissues are actively infected, such unfavorable conditions are not ideal for surgical treatment.
