Department of Pediatric Endocrinology and Rheumatology, Institute of Pediatrics, Karol Jonscher's Clinical Hospital, Poznan University of Medical Sciences, Poznan, Poland.

The term 'hyperthyroidism' refers to a form of thyrotoxicosis due to inappropriate high synthesis and secretion of thyroid hormone(s) by the thyroid. The leading cause of hyperthyroidism in adolescents is Graves' disease (GD); however, one should also consider other potential causes, such as toxic nodular goitre (single or multinodular), and other rare disorders leading to excessive production and release of thyroid hormones. The term 'thyrotoxicosis' refers to a clinical state resulting from inappropriate high thyroid hormone action in tissues, generally due to inappropriate high tissue thyroid hormone levels. Read More

Radioiodine therapy of thyroid autonomy.

Jérôme Clerc

Q J Nucl Med Mol Imaging 2021 Jun 10;65(2):138-156. Epub 2021 Feb 10.

Department of Nuclear Medicine, Cochin Hospital, DMU Imagina, Paris University, Paris, France -

Radioiodine therapy (RIT) of thyroid functional autonomy (TFA) is rapidly evolving, though it has been recognized for decades as a very effective treatment of toxic nodular varieties. Indeed, TFA is a frequent cause of persistent subclinical hyperthyroidism, which should be regarded as a new metabolic syndrome, with well-established adverse cardio-vascular consequences. Sensitive TSH assays and multiparametric ultrasounds are not accurate enough to reliably diagnose TFA and identify its main variants, unifocal, multifocal (UFA/MFA) and disseminated autonomy (DISA).
