Abstract
Background: Thyroid storm is a rare, life-threatening condition characterized by severe clinical manifestations of thyrotoxicosis and can be precipitated by several factors. We described a thyroid storm precipitated by a long-term treatment using homeopathic medicine containing iodine.
Case presentation: A 55-year-old Italian woman was admitted to our Sub-Intensive Care Unit with the diagnosis of congestive heart failure and thyrotoxicosis. She has been diagnosed with Graves’ disease two years before; she refused conventional therapy and in the preceding six months had been using phytotherapeutic and homeopathic medicine. We found serum and urine iodine levels consistent with severe intoxication by iodine (serum iodine: 42100 mcg/L and urinary iodine: 4223 mcg/L, respectively). After a few hours, the patient went into cardiac arrest. She was subjected to invasive ventilation, dialyzed with continuous veno-venous hemofiltration and treated with vasoactive amines.
Conclusion: The high level of iodemia manifested in our patient - around a thousand times greater than the normal range and itself associated with fatal outcomes - was caused by long-term homeopathic treatment. This long-term treatment has two consequences: first, iodine load-precipitated hyperthyroidism in thyroid storm, and secondly, it prevents us from treating patients with inorganic iodide.

Abstract
Background: The normal reference values for the thyroid uptake of radioactive iodine and Tc-99m pertechnetate in euthyroid patients vary by geographical location as well as the amount of iodine intake in the diet. The present study examines the normal reference values for thyroid uptake of Tc-99m pertechnetate in the North of Iran.
Methods: The participants of this study were 64 patients (all over 20 years of age) who had referred to the Nuclear Medicine Center of the Shahid Beheshti Hospital for thyroid scan over the period between March 2018 and May 2020. It is worth mentioning that relying on laboratory test results, only patients with normal thyroid function were included in this cross-sectional study.
Results: The median, the 5th and 95th percentiles and thyroid uptake range of 99mTc-pertechnetate in euthyroid patients were 0.9, 0.6 to 1.8% and 0.54 - 1.80%, respectively.
Conclusion: The percentage of uptake in the thyroid gland in each geographical area varies based on race and diet content, so it is necessary to determine the percentage of uptake in each specific region and even check it periodically.
