The aim of this study was to compare the efficacy of different PEG tube removal methods in the management of buried bumper syndrome in a large retrospective cohort.

Acute phase reaction to gadolinium-DTPA in dialysis patients.

Background: Several late sequelae of the administration of gadolinium (Gd)-containing MRI contrast agents have been described in patients with advanced renal failure. In an observational series, we found a remarkable frequency of peracute reactions after administration of Gd-DTPA used for cardiovascular evaluation before renal transplantation.

Methods: In a 26-month observational period, 13 of 136 haemodialyzed or CAPD patients exhibited onset of fever, chills and nausea within hours after administration of Gd-DTPA peracute.
