Effects of low-iodide diet on postsurgical radioiodide ablation therapy in patients with differentiated thyroid carcinoma.

Objective: Most patients with differentiated thyroid carcinoma (DTC) undergo total thyroidectomy followed by routine radioiodide thyroid remnant ablation. Most centres that routinely perform radioiodide ablation prescribe a low-iodide diet (LID) to increase the radioiodide accumulation in thyroid remnants. The efficacy of an LID on thyroid remnant ablation, however, has never been demonstrated convincingly.

Sandostatin LAR in acromegaly: a 6-week injection interval suppresses GH secretion as effectively as a 4-week interval.

Introduction: Depot preparations of long-acting somatostatin analogues are being used increasingly in the treatment of GH hypersecretion in patients with acromegaly, either as primary treatment or as secondary treatment following incomplete surgery. In 60% of these patients, Sandostatin long-acting release (LAR), the depot preparation of octreotide, achieves effective suppression of serum GH (< 5 mU/l) and IGF-I levels. The advice is to administer Sandostatin LAR at 4-week intervals.
