Nonocclusive hemorrhagic necrosis of the intestine.

Hemorrhagic intestinal necrosis occurs without demonstrable mechanical obstruction of the mesenteric vascular supply. The etiologic factors include (1) congestive heart failure, (2) cardiac arrhythmia, (3) dehydration, and (4) digitalis therapy with or without digitalis toxicity. All of these factors have been shown to result in a decrease in splanchnic blood flow. The outcome of this disease has invariably been fatal. Early recognition and nonoperative management directed toward increasing splanchnic blood flow are the most significant factors in the survival of patients.

Arc technique for total-body irradiation by a 42-MV betatron.

An arc technique for total-body irradiation (TBI) has been developed using a Siemens 42-MV betatron. Dose is administered with the isocenter approximately one-third the distance from source to patient. A modified inverse-square function for a beam arcing isocentrically was derived and confirmed experimentally. Relationships between stationary and arcing beam equilibrium and depth doses have been established theoretically and experimentally. Depth doses for TBI by 42-MV beams are compared with those for 60Co and 4-MV beams. The simplicity of setup and short treatment times are comparable to setup and treatment times of 60Co and linear accelerator TBI techniques.
