CHRONIC gonorrheal infections have been a menace to civilization ever since ancient times; and, although medical science has done much to alleviate suffering in the great majority of cases, there are still a few of the most chronic gonorrheal infections that fail to respond to general medical treatment, as it is practised to-day. Years before the Great War, and more especially since that event, governments, states, and provinces formed dispensaries for treatment, control, and supervision of patients afflicted with gonorrhea. In Saskatchewan, since the Great War, public dispensaries have been opened and operated under the control and supervision of the Health Department of the Province. These dispensaries are manned by specially trained medical officers, and well selected laboratory assistants, but in the course of time the dispensaries gradually have accumulated a group of cases the smears of which remained positive for diplococci, in spite of prolonged and intensive medical treatment. The Health Department, deciding not to discharge these patients until a cure was effected, realized that some remedy must be found, or these patients would become public charges on the Province for life, also menaces to the public as carriers of infection. In the year 1924, the Health Department learned that Dr. H. E. Young, of British Columbia, had had encouraging results by using deep X-ray treatment on several cases of chronic gonorrheal infection. On the strength of Dr. Young's report, I was instructed by the Provincial Health Department of Saskatchewan to undertake the treatment of six female cases. The case reports pertaining to their physical conditions before and after treatment are appended to this paper. Since I treated these, ten private patients have received similar treatment, with like results. The six cases selected for deep X-ray therapy were all suffering from chronic gonorrhea of long standing, the infection having been present for from two to nine years. Each patient had received intensive medical treatment, consisting of iodine, saline, soda, or lysol douches, all depending on the condition of the cervix; silver nitrate, or glycerin, and carbolic applications to the cervix, twice weekly, and sitz-baths twice weekly. Smears taken showed in every case the presence of pus and gonococci. Discharge in all the cases was of the same kind, being thick, profuse, and of a greenish-yellow color. Two of the patients complained of pains over the region of the tubes, and one patient had had a previous salpingectomy. All had edema and erosions of the cervix. The X-ray technic was the same for each patient, regardless of age, physical condition, physique, or duration of the infection. Treatment was given through two portals of entry—one anterior pelvic, and one posterior pelvic, namely: F.S.D., 50 cm., K.V., 200 peak; filtration, 3/4. Cu and 1 mm. Al; 5 ma.; time, 60 min. for each port of entry. Treatments were given on alternate days.
