2. ENDOCRINOLOGY

Making use of Lakshmanan et al definite prohibitions, and Maxon et al. lists of allowed foods, the author worked out a richer, comprehensive and autoexplicit diet. The mechanisms of uptake increase, the efficiency in favoring iodine depletion and scanning, the potential benefit for I-131 ablation, but unproved for I-131 treatment of differentiated thyroid cancer, are exposed. The usefulness of urinary iodine assay to avoid contamination, to advise a LID need, to appraise adherence to, and efficiency of LID, is stressed. It is to regret non-adoption of LID in face of increased iodine intake, as it is to condemn increase in I-131 dose, in this context, since LID is quickly efficient and harmless. In countries like Brazil, an algorithm is suggested: 1. To estimate foods iodine content, or 2. To obviate contamination, by urinary iodine assay, or 3. To prescribe a LID. The axiom: "Maybe sometimes LIDs are unhelpful, contamination is allways harmfull" is proposed.
