A worldwide increase in pediatric thyroid cancers incidence over the years has been observed. Although pediatric thyroid cancers tend to have a more aggressive course compared to adults, the survival rate is better. In this study, we aimed to examine the demographic, clinical, pathological, and laboratory characteristics, prognostic and risk factors of children with thyroid cancer.Methods: We retrospectively analyzed 39 children with thy...

Introduction: Hashimoto's thyroiditis (HT) and Graves' disease (GD) become increasingly common in children's population. Pathogenesis of autoimmune thyroid diseases (AITD) bases on coexistence of genetic predisposition and environmental triggers which finally drive to breakdown of immune tolerance. Many mechanisms in human body moderate process of inflammation. While some of them answer for up-regulation, some agents like B regulatory lymphocytes (...

Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. Autoimmune thyroid dysfunctions (Hashimoto's thyroiditis and Graves' Disease) are described in the literature as the most common autoimmune disease after thymic transplant.<p class="...

Introduction: The most common causes of hyperthyroidism in the pediatric age group are autoimmune conditions (Graves' disease or Hashitoxicosis). Hyperfunctioning thyroid carcinomas are rarely reported. In this case report, we present a 17-year-old girl who was diagnosed with papillary thyroid carcinoma upon testing for hyperthyroidism.Case: A 17-year-old girl had presented to another center with a 1-month history of...

Background: Thyroid nodules are quite common in the adult population (13%)but are relatively rarely diagnosed in childhood (0.2-5%).There is a significantly higher risk of malignancy of paediatric thyroid nodules than that in adult patients. The authors of this publication present the observations of the occurrence, diagnosis, and treatment of patients with thyroid nodules in the Department of Pediatric Endocrinology and Diabetology, Medical University...

Background: Nontoxic multinodular goiter (MNG) is frequently encountered in the general population, but little is known about the underlying genetic susceptibility to this disease. Recently, germline mutations in DICER1, a gene that codes for an RNase III endoribonuclease, have been identified in familial MNG with and without Sertoli-Leydig cell tumor of the ovary.Objective: We reporteda family exhibiting various thyroid diseases in which a ...

HLA Alleles and Amino Acid Variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 Molecules in Early-Onset Autoimmune Thyroid Disease

Cho Won Kyoung , Shin Dong Hwan , Kim Seul Ki , Lee Seonhwa , Choi Yujung , Ahn Moonbae , Baek In Cheol , Jung Min Ho , Kim Tai-Gyu , Suh Byung-Kyu

Objective: We try to investigate the polymorphisms and amino acid variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 molecules in early-onset AITD.Methods: The genotypes of HLA-A, B, C, DRB1, DQB1, and DPB1 on AITD were analyzed in 102 Korean children with AITDs (Graves’ disease (GD)=62, Hashimoto’s disease (HD)=40) and 142 healthy control using sequence-based typing. Analysis of variant amino acids was performed across the genotyping results with ...

Evaluation of Serum Concentrations of Selected Cytokines OPG and sRANKL in the Diagnosis of Autoimmune Thyroid Disease in Children

Mikos Hanna , Mikos Marcin , Niedziela Marek

Chronic autoimmune thyroiditis (cAIT) and Graves’ disease (GD) is the most common autoimmune disorders in children, associated with induction of inflammation and autoimmunity process. OPG, a cytokine receptor which mediates suppressive effect on osteoclastogenesis and its soluble ligand RANKL (sRANKL) are regulators of inflammation and may be a link between bone, autoimmune disease, and vasculature.Aim of the study: We hypothesized that cytokines OP...

Encephalopathy Associated with Autoimmune Thyroid Disease: A Case Report

Lantigua Hector , Yafi Michael

Background: Encephalopathy associated with autoimmune thyroid disease (EAATD) is very rare in pediatrics. Contributing factors include: Sudden change is thyroid levels, cerebral vasculitis,endothelial inflammation or immune complex deposition, global cerebral hypoperfusion, as well as cerebral tissue-specific autoimmunity.The case: A 16-year-old female was diagnosed with hyperthyroidism and treated with Radio Iodine Ablation (RIA). Her total T4 level was...

Amiodarone Induced Hyperthyroidism in a Pediatric Patient

Marques Bernardo , Oliveira Sofia , Laranjo Sergio , Lopes Lurdes

Introduction: Thyroid dysfunction is the most common side effect of amiodarone therapy, ranging from subclinical changes to overt clinical thyrotoxicosis (AIT) and/or hypothyroidism (AIH). Two major types of AIT have been described: type I usually develops in multinodular goiter or in preexisting Graves’ disease where an overload of iodine is responsible for the overproduction of thyroid hormones, and type II presents as a destructive thyroiditis, with release of pre-form...
