Evaluation of LeVeen-shunt patency using Tc-99m labelled macroaggregated albumin.

A LeVeen peritoneo-venous shunt is placed for intractable ascites. Determination of obstruction site in the shunt tube is a difficult problem. We describe a simple nuclear medicine method using 111MBq (3mCi) of Technetium-99m labeled macro-aggregated albumin injected intraperitoneally.

Frequency and clinical importance of anti-Tg auto-antibodies (ATG).

Objective: To note the frequency of anti thyroglobulin autoantibodies (ATG) and its clinical importance in 25 follow-up cases of differentiated thyroid cancer (DTC).

Design: A case control study.

Place And Duration Of Study: The total duration of study was one year (September 2000 to August 2001).
