Possible Problem with Prostate Radioactive Seed Implant
Radioactive Iodine containing tiny seeds are implanted in the prostate to treat prostate cancer. Researchers at the Cleveland Clinic Foundation were performing routine tests to check for possible radioactive seed migration to other parts of the body. Since late in 2001, 23,184 seeds were implanted in the 246 patients who were evaluated. Of these, 75 seeds were found in the urine, and 25 migrated to the thorax. However, in this possibly unique case, the seeds in the prostate became damaged, the radioactive Iodine escaped and migrated to the patient's thyroid gland. The amount found in the thyroid was not enough to be clinically important according to the researchers, however radioactive Iodine can damage the thyroid gland and decrease the metabolic rate. The case report is published in the November 2004 issue of the Journal of Urology.

Meta Analysis Shows that NAC Protects the Kidneys During Heart Test
When cardiologists test the heart muscle and surrounding blood vessels they use a radioactive contrast media given by injection to give a better picture on the X-ray. Unfortunately, a common effect of this contrast media is kidney damage.
In this meta-analysis of 5 trials that included patients with existing kidney damage who were placed on NAC in double-blind, placebo-controlled studies it was found that NAC decreased kidney damage by 20%, and that there was a 70% decreased risk in contrast induced kidney disease. The study is published in the November 2004 issue of the journal Clinical Cardiology.
