Background: Thyroid hormone plays a key role in bone mineral homeostasis and significant alterations in its circulating levels have been associated with an impairment in skeletal growth during childhood. To date, the effects of subclinical hypothyroidism (SH) on bones have not been studied and the management of this condition is still debated.Aim: To evaluate bone mineral density (BMD) in children with mild, persistent S...

Objective: Neonatal hyperthyroidism is a severe but generally transient condition with a 2% prevalence in offspring of mothers affected by Graves' disease. It is caused by the transplacental passage of maternal anti-thyrotropin receptor stimulant antibodies (TRABs). Here we report the cases diagnosed at our centre between 2015-2019 in order to re-evaluate the diagnostic and therapeutic approach to this challenging neonatal thyroid alteration.<p cla...

Background: The prevalence of vertebral fractures (VF) in Duchenne Muscular Dystrophy (DMD) is currently unknown as systematic spine imaging is rarely performed.Objective: To determine the prevalence of VF in DMD and factors associated with VF.Method: A prospective study utilising systematic screening with DXA vertebral fracture assessment (VFA) was performed in all 47 eligible boys. 6/47 were excluded due to spinal instrumentation...

Objectives: Preterm infants often present CH characterized by delayed TSH elevation. We describe the clinical and biochemical features and the evolution of CH in preterm infants with delayed TSH elevation, detected by the second screening for CH.Material and Methods: All preterm infants born between 2007 and 2014 negative to the first screening (b-TSH<10 mcU/ml) at 2–5 days of life and positive to the second screening at 12–33 days (b-TSH&#...

Background: The N-acetyltransferase 2 (NAT2) A803G polymorphism leading to substitution of lysine to arginine at residue 268 and codifying for a cytosolic enzyme catalysing acetyl-CoA-dependent N- and O-acetylation reactions, has been associated with decreased insulin sensitivity in a large adult population with the A allele associated with insulin resistance (IR)-related traits.Objective and hypotheses: We screened for this polymorphism, for th...

Background: Childhood cancer survivors (CCS) are at risk for low bone mineral density (BMD).Objective: Aim of our study was to evaluate the prevalence of low BMD and it’s determinants in a single-center cohort of CCS.Method: One-hundred-eighty-five CCS (103M, 84F) diagnosed with liquid-LT-(n=48), solid-ST-(n=88) and brain tumor-BT-(n=51) at the age of 5.3±3.2 years underwent height, BMI (SDS), T...

Background: Over 90% children grow normally, and attain final height within their genetic target. Up to 10% of all children do not spontaneously catch-up by the age 3 years, besides some cases of TS are diagnosed late, and others with SGA go undiagnosed and unattended.Objectives & Hypothesis: Early screening of growth patterns in children attending Child Protection Visits (PMI, France) in Dreux district. Our objective was the evaluation of prevalence...

Background: The management of subclinical hypothyroidism (SH) is still challenging in particular for mild forms with TSH levels ranging between 4.5 and 10 mU/L.Objective and hypotheses: to compare left ventricular (LV) geometry and function of SH subjects and matched euthyroid controls, and to evaluate the effect of L-thyroxine (L-T4) therapy on cardiac parameters.Method: Thirty-six (36) children (19 females and 17 males), aged 8.6...

Background: Autoimmune hepatitis (AIH) and methimazole (MMI)-induced toxic hepatitis are both rare diseases in pediatric age.Case presentation: We present the case of a 15-year-old girl affected by idiopathic arthritis and autoimmune thyroiditis. The autoimmune thyroiditis was diagnosed at 13 years of age. At 15 years old she developed hyperthyroidism (TSH <0.01 mcU/ml, FT4 2.3 ng/dl, FT3 8.4 pg/ml, TRAb 18 IU/l) and was treated with MMI (0.28 mg/kg ...

Background: It had never been investigated to now whether the course of thyroid function in Hashimoto’s thyroiditis (HT) may differ in the children who had presented with either euthyroidism or subclinical hypothyroidism (SH).Objective and hypotheses: To establish, by means of a 5-year prospective evaluation of 234 children with HT and no prognostic risk factors, whether thyroid status evolution over time may be conditioned by the biochemical patter...
