Dentures as artificial saliva reservoirs in the irradiated edentulous cancer patient with xerostomia: a pilot study.
Dentures which included a reservoir for dispensing artificial saliva were constructed for a trial group of patients with oropharyngeal cancer seen in the postirradiation period. The tumors were apparently under control, but the patients were suffering from xerostomia. Details of the design, construction, and use of such a device are presented. The subject of postirradiation xerostomia in the edentulous patients is reviewed, and recommendations for reducing the incidence and severity of this condition are given. The prosthesis contributed to successful oral rehabilitation of half the trial group of patients with postirradiation xerostomia.
Intracavitary irradiation of renal pyelocalyceal transitional cell carcinoma with iridium-192.
A case of multicentric urothelial transitional cell carcinoma is presented, in which the patient underwent a left ureteronephrectomy and in the remaining right kidney recurrent transitional cell carcinoma was found in the inferior calyx. Because this area was accessible via a cutaneous nephrostomy, it is treated with a combination of external beam radiation and intracavitary implantation with iridium-192. The iridium was placed in the vicinity of the tumor using an angiographic procedure. The technique successfully preserved remaining renal parenchyma. The case illustrates how angiography skills and procedures can be applied in a novel brachytherapy application.
A simple system for detecting patient movement during radiation therapy.
The authors described a system which detects patient movement while that patient is undergoing radiation treatment. The system consists of simple and inexpensive electronic circuitry using the laser localization lights commonly used with an isocentric linear accelerator. If the patient moves, a visual or audible signal alerts the radiation-therapy technologist who can interrupt treatment and reposition the patient. The verification of proper patient position using this technique compares favorably with the routine use of cerification radiographs.

The vacuum cassette for improved linear accelerator portal films.
The use of a commercially available vacuum cassette with lead screens for linear accelerator portal films is described. The vacuum cassette technique provides improved quality with no increase in patient discomfort or cost and avoids gemoetric distortion, compared to other currently available methods.
A device for insuring the congruency of opposed irregularly blocked fields.
A device for insuring the congruency of opposed irregularly blocked fields has been developed which permits the treatment of both fields of a parallel opposed pair without the realignment of any field-shaping standard non-divergent blocks. The device is an adaptor which attaches directly to the shadow tray or wedge holder and provides 2 channels for 1 Lucite shadow tray. A mirrow-image field is obtained without disturbing the position of the blocking array. Set-up times are decreased.
Retroperitoneal germinoma marked by elevated serum lactic dehydrogenase.
A case of primary retroperitoneal germinoma is presented in which markedly elevated serum lactic dehydrogenase levels were present before diagnosis, but declined to normal with abdominal irradiation. It is the first report of lactic dehydrogenase serving as a tumor marker in germinoma.
