BACKGROUND: Hypothyroidism is associated with obesity, and thyroid hormones are involved in the regulation of body composition, including fat mass. Genome-wide association studies (GWAS) in adults have identified 19 and 6 loci associated with plasma concentrations of thyroid stimulating hormone (TSH) and free thyroxine (fT4), respectively. OBJECTIVE: This study aimed to identify and characterize genetic variants associated with circulating TSH and fT4 in Danish children and adolescents and to examine whether these variants associate with obesity...

BACKGROUND: Suboptimal thyroid hormone therapy including under-replacement and over-replacement is common amongst patients with hypothyroidism. This is a significant health concern as affected patients are at risk of adverse cardiovascular or metabolic consequences. Despite a growing body of evidence on the effects of various factors on thyroid hormone replacement, a systematic appraisal of the evidence is lacking. This review aims to appraise and quantify the extent to which clinical, behavioural and pharmacogenomic factors affect levothyroxine therapy in patients with primary hypothyroidism...

Zoe, a 13-year-old white girl, presents as a new patient to your pediatric clinic with complaints of frequent emesis, anxiety, and learning problems, and previous diagnosis of cerebellar ataxia. Parents accompany Zoe and state, "it is really hard for her to go out, she gets sick and falls easily." She was born full term by vaginal delivery without complications. Given globally delayed milestones, she received early intervention services. Feeding problems began at infancy, including gastroesophageal reflux and aspiration pneumonia...

Purpose: To screen the global development of children with and without congenital hypothyroidism and to investigate the association between fine motor skills and expressive language development in both groups. Methods: This is a prospective study of a cohort of children diagnosed with Congenital Hypothyroidism and monitored in a reference service for congenital hypothyroidism of a public hospital and of children without this disorder. The screening was performed using the Bayley Scales of Infant Development III in the cognitive, gross and fine motor skills, and receptive and expressive language domains...

The follow-up of celiac disease (CD) is challenging due to the scarcity of published data and the lack of standardized evidence-based protocols. The worldwide frequency and methods of CD follow-up appear to be heavily influenced by expert opinions of the individual physicians who assess children with CD. The aim of this review was to summarize the available studies on CD follow-up in children. We conducted a literature search with the use of PubMed, Medline, and Embase (from 1900 to 15 December 2016) for terms relevant to this review, including CD, follow-up, dietary adherence or dietary compliance, nutrition, comorbidities, complications, and quality of life...

Since ancient times in South Tyrol there was evidence of endemic goitre caused by iodine deficiency. In the early 80's an epidemiological research on adults and primary and secondary school children reported in the least a prevalence of goitre from grade 1 B-3 (WHO) of 23,66% (limits WHO >5%) and an urinary iodine of 10,2 µgI/L. Therefore South Tyrol population presented heavy endemic goitre. In 1982 started a generalized iodine prophylaxis with alimentary iodined salt after an intense prevention campaign...

BACKGROUND: Iodine is an essential nutrient required for the biosynthesis of thyroid hormones, which are responsible for regulating growth, development and metabolism. Iodine requirements increase substantially during pregnancy and breastfeeding. If requirements are not met during these periods, the production of thyroid hormones may decrease and be inadequate for maternal, fetal and infant needs. The provision of iodine supplements may help meet the increased iodine needs during pregnancy and the postpartum period and prevent or correct iodine deficiency and its consequences...

We assessed thyroid abnormalities in a large cohort of children with DS. METHODS: Retrospective records review from a single institution. Calculated prevalence of common thyroid abnormalities and associations with common comorbidities. RESULTS: Among 508 patients, 120 (24%) had a thyroid-related diagnosis, the majority having elevated thyrotropin treated with levothyroxine...

Background Subclinical thyroid disease during pregnancy may be associated with adverse outcomes, including a lower-than-normal IQ in offspring. It is unknown whether levothyroxine treatment of women who are identified as having subclinical hypothyroidism or hypothyroxinemia during pregnancy improves cognitive function in their children. Methods We screened women with a singleton pregnancy before 20 weeks of gestation for subclinical hypothyroidism, defined as a thyrotropin level of 4.00 mU or more per liter and a normal free thyroxine (T4) level (0...

Back ground: Thyroid hormone (T3) is essential for normal development of children enabling brain development and somatic growth. However, certain individuals are genetically predisposed with insufficient or no thyroid hormones. Such a condition is termed congenital hypothyroidism (CH). OBJECTIVE: In the present review, a brief back ground about congenital hypothyroidism, factors associated with CH leading to thyroid dysgenesis and thyroid dyshormonogenesis is elaborated. Additionally, the guidelines for available treatment options, management and follow-up required for patients diagnosed with CH are discussed...

OBJECTIVE: To investigate the characteristics of DUOXA2 gene mutation and the genotype-phenotype relationship in children with congenital hypothyroidism (CH) in Guangzhou, China. METHODS: A total of 20 CH patients with suspected thyroid dyshormonogenesis who had no DUOX2 gene mutation were enrolled. These patients who were born between 2011 and 2012 were screened and diagnosed with CH in the Guangzhou Newborn Screening Center.
