- Autonomous Functioning Thyroid Nodule in a 4-year-old Male Child Treated with Radioiodine (I-131). Khare, Abhishek; Bhutani, Puneet; Chauhan, Suneel // World Journal of Nuclear Medicine;May2013, Vol. 12 Issue 2, p65
Autonomous functioning thyroid nodules that cause toxic manifestations (toxic adenomas) are benign monoclonal tumors characterized by their capacity to grow and produce thyroxine (T4) and triiodothyronine (T3) autonomously, i.e. in the absence of thyrotropin thyroid stimulating hormone. Toxic...
- A New Case of Familial Nonautoimmune Hyperthyroidism Caused by the M463V Mutation in the TSH Receptor with Anticipation of the Disease Across Generations: A Possible Role of Iodine Supplementation. Massimiliano Ferrara, Alfonso; Capalbo, Donatella; Rossi, Giuseppina; Capuano, Serena; Del Prete, Giuseppina; Esposito, Valentina; Montesano, Giovanna; Zampella, Emilia; Fenzi, Gianfranco; Salerno, Mariacarolina; Emidio Macchia, Paolo // Thyroid;Jul2007, Vol. 17 Issue 7, p677
Objective: Hereditary (familial) nonautoimmune hyperthyroidism (FNAH) is caused by activating thyroidstimulating hormone (thyrotropin) receptor (TSHR) germline mutations. We describe a family with recurrent thyrotoxicosis and goiter across three generations, including an 8-year-old girl. Main...
