Lung uptake on technetium-99m-MDP bone scan in Wegener's vasculitis.

A 99mTc-MDP bone scan was performed on a 65-yr-old woman because of joint pain. The study showed bilateral lung uptake and no abnormalities of the affected joints. Wegener's vasculitis was diagnosed.

Short dialysis with a polyacrylonitrilmembrane (RP 6) without the use of a closed recirculating dialyzate delivery system.

Because of excessive eltrafiltration (UF), the RP 6 dialyzer requires a closed recirculating dialyzate delivery system. The purpose of this study is to present the characteristics of the RP 6 dialyzer on a single needle system which programs the UF rate of this dialyzer. The single needle system consists of one blood pu-mp and two roller pump heads, switched on and off at preselected maximum and minimum out let pressures (OP).
