Exercise is one of the most important components, together with insulin therapy and diet, in the clinical management of type 1 diabetes mellitus (T1DM). Physical activity has multiple health benefits, like blood pressure reduction, improvement of cardiovascular fitness and lipoprotein profile. The benefits for children with diabetes may also include positive effects on glycemic metabolism. The following review examines the main studies about the effects of exercise on diabetes. Additional longitudinal studies are needed to verify the hypothetical positive relationship between sport and T1DM and between sport and diabetic complications. However, aerobic and moderate intensity physical activity in children and adolescents with T1DM should be encouraged also for its beneficial psychological effects.

Ten patients with progressive CRF were studied for the major indices of glycolipid metabolism during the first application of peritoneal dialysis. From the 2nd hour the concentration of dialysis fluid is 4.5 g%, while the electrolyte content is unchanged. During treatment a constant increase of glycemia and insulinemia with a fall of plasma-free fatty acids and serum triglycerides was observed. The authors attribute such modifications to hyperglycemia and consequently to the high glucose of the dialysis bath.

A series of 10 patients with a primary non-Hodgkin lymphoma of the central nervous system were observed and treated by the authors. All were diagnosed after a pathologic examination of the surgical material; the lesions were supratentorial in all cases and unifocal in 9. In every case radiation therapy improved clinical conditions and in most cases even radiologic features of the patients. Four patients were alive and without evidence of disease many months after therapy. Four patients died with a relapse in the central nervous system; 3 of them had disseminated disease at the time of death. Two patients died for an unknown cause. Radiation therapy was performed with 60Co source with 2 opposed portals and the whole brain irradiation technique in all cases but 2. Doses ranged from 35 to 54 Gy. The recent literature on this uncommon disease and the most adequate therapeutic possibilities of radiation therapy and chemotherapy, or both, are discussed.
