Surgical resection followed by radioactive iodine ( 131 I) therapy constitutes a standard treatment for differentiated thyroid cancer. 131 I is normally excreted through the kidneys, and treatment of patients with end-stage renal disease on hemodialysis requires special attention to the dose of 131 I, the timing of dialysis, and radiation safety. We present a case of end-stage renal disease in a postthyroidectomy patient on hemodialysis who required radioactive iodine ablation, and we review the literature.

Purpose of the Study: Radioiodine (I-131) is used as an effective noninvasive treatment for thyroid malignancies. Salivary gland is one of the most affected nontarget organs. The present study aims to perform early quantification of salivary gland function after I-131 therapy (RIT) for thyroid cancer considering I-131 down-scatter in the Tc-99m window. Materials and Methods: A total of 20 patients (6 males and 14 females) with differentiated thyroid carcinoma were enrolled in the study. Baseline dynamic salivary scintigraphy was performed in all patients using 185–370 MBq (5–10 mCi) Tc-99m pertechnetate. Posttherapy, salivary scintigraphy was performed 10–25 days after RIT in the range of 1.85–7.4 GBq (50–200 mCi). Time–activity curves obtained from the pre- and posttherapy dynamic salivary scintigraphy were used for semi-quantitative analysis. Uptake ratio (UR), ejection fraction (EF%), and maximum accumulation (MA%) were calculated by drawing regions of interest of individual parotid and submandibular glands over a composite image, after correcting for down-scatter from I-131 in the Tc-99m window. A paired t -test was used for comparison of the parameters obtained. Results: Significant changes were observed in UR and EF% of both parotid and submandibular glands ( P < 0.05). No significant changes were found in the value of MA% of left parotid gland and both submandibular glands in the posttherapy scans in comparison to pretherapy scans ( P > 0.05). However, significant difference was observed in the MA% of the right parotid gland ( P = 0.025). Conclusion: Salivary gland function was found to deteriorate after RIT, with the parotid glands affected more than the submandibular glands.

Keloid, hypertrophic scars and basal cell carcinoma (BCC) falls under the category of non-melanoma skin cancer. Intralesional steroids, external beam radiation therapy, 5-Fluorouracil, cryotherapy, laser, etc are the available treatment options. However, recurrence has been reported with each type of treatment mode. In the present article, various treatment modes have been discussed and institutional experience of Rhenium-188 skin patches for the treatment of keloids and BCC has been discussed.
