Postoperative irradiation of brain ependymomas. Analysis of 33 cases.

Treatment and final outcome of 33 patients with brain ependymoma were reviewed. All patients had been operated, but the surgical removal was incomplete in the great majority of cases. Radiation therapy was subsequently performed using one of the following techniques; a) partial brain irradiation against the primary involved areas in 17 cases, b) whole brain irradiation plus boost against primary involved sites in 6 cases and c) total craniospinal irradiation in 7 cases. Three patients were not eligible for the present study because of underdosage. Five- and 10-year survival rates were 48 and 38% respectively. A short survey of recent literature is presented. The possible causes of failure and the methods for postoperative irradiation are discussed against the background of literature and our own cases.

Accuracy of computed tomography in the screening of obstructive jaundice.

Percutaneous transhepatic cholangiography (PTC) has come back into greater use thanks to Chiba's needle. PTC, however, is useful only in obstructive jaundice (OJ). Since in OJ the dilatation of the intrahepatic biliary tract (IHBTD) is constant, the authors discussed CTs reliability in evaluating IHBTD in a series of 33 patients with OJ studied with PTC. The threshold of CT diagnosis of IHBTD was found to be equal to a doubled caliber of the normal biliary tract. This value is reached by 85% of the patients 2 weeks after the onset of OJ and in 98% between 2 and 3 weeks. CT is therefore usable as a screening method of PTC, as long as it is not performed before 2 weeks after the onset of OJ. After 2 weeks, if CT does not reveal IHBTD, it is possible to exclude OJ.

[Surgery in radioactive patients (author's transl)].

The authors discuss some legal aspects and protection problems relative to surgical procedures involving radioactive patients, also in the light of recent European guidelines. They analyse in particular the radiation risk associated with the more common cases concerning radioactive substances that are administered for diagnostic purposes. This study affords a preliminary evaluation of the risk inherent in such surgery, in the light of experimental measurements.
