[Experience in the surveillance of arteriovenous fistula in Verbania, Italy].

One hundred forty-five patients are receiving renal replacement therapy at our center: 127 are on hemodialysis, 18 on peritoneal dialysis. From 2000 through 2005 a total of 215 arteriovenous fistulas (57% distal, 31% proximal, 12% prosthesis) were created. After some time we felt the necessity to design a vascular access surveillance system because the uremic population was increasingly constituted by aged people, including many diabetics and people suffering from hypertension with generalized vascular disease.

[Herpetic encephalitis with biphasic course. A case report and review of the literature].

Encephalitis represents an important event in pediatric practice. Between the different causes Herpes Simplex Virus (HSV) seems to be the most significant etiological agent, not only for its frequency but chiefly for conditioning prognosis. The Authors report a new case of HSV encephalitis with biphasic course illustrating the most recent pathologic, diagnostic and therapeutic features in the attempt to individualize those factors, between clinical data, laboratory findings and imaging that allow early diagnosis and consequently precocious specific antiviral therapy.

[Radiologic aspects of metastasis to the colon. Description of 4 cases].

The paper describes four cases of metastatic colon emphasizing its radiological aspect, represented by irregular and eccentric stenoses with stiffness and angling of the colon segments involved. In three cases, peritoneal carcinomatosis was also present and its radiological aspects (ascites, mesentery and omentum thickening, small intestine infiltration) were investigated by CT.
