Thyroid Function in Children Affected By Congenital Hypothyroidism (CH) with Eutopic Thyroid After Discontinuation of Treatment with Levothyroxine

Poggi Elena , Gastaldi Roberto , Muraca Monica , Perri Katia , Pistorio Angela , Maghnie Mohamad

Objective and hypotheses: We analysed the prevalence of transient hypothyroidism in a cohort of children affected by CH with eutopic thyroid after Levothyroxine discontinuation.Method: 77 newborns (36 females, 41 males) affected by CH with eutopic thyroid from 1999 to 2011 were enrolled. The confirmation diagnosis of CH after screening was made within the first 15 days of life by assessing TSH value (mean 74.4±82.2 μU/ml n.v 0.5–4.2) and f...

Background: An important issue in the management of congenital hypothyroidism (CH) is the best initial dose of levothyroxine (L-T4) in order to achieve optimal neurocognitive outcomes. Both European and American guidelines suggest an initial dose of 10–15 μg/kg per die but trials on long-term effects of different doses within this range are lacking.Objective and hypotheses: This was a multicenter randomized trial to ev...

Background: Central precocious puberty (CPP) is defined as the secondary sexual characteristics onset before 8 years of age in females and before 9 in males, due to premature activation of the hypothalamic-pituitary-gonadal axis. The underlying cause remains idiopathic in the great majority; based on the 2009 Consensus, 2% to 7% of girls who have onset of CPP between the ages of 6 and 8 years have unsuspected pathology and only 1% have a tumor such...

Do Different Initial Doses of L-T4 within the Range of 10-15 mcg/kg/day Influence Neurodevelopment during the First Two Years of Life in Children with Congenital Hypothyroidism?

Background: The initial L-T4 dose currently recommended in the treatment of congenital hypothyroidism (CH) is 10–15 mcg/kg per day.Objective and hypotheses: We designed a multicenter randomized trial to evaluate the effects of different starting doses of L-T4 within the range 10–15 mcg/kg per day on neurocognitive development in children with CH.Method: Seventy-two children with CH diagnosed by neonatal screening were enr...

Objectives: To evaluate the potential diagnostic role and sensitivity of T2-weighted DRIVE sequence in pituitary stalk (PS) identification and measurements in patients with hypothalamic-pituitary disorders. The degree of agreement and reliability between standard pre- and post-contrast T1-weighted images and T2-DRIVE will be tested in a large group of patients with pituitary dysfunction.Design: We searched for pituitary MRI reports using ‘T2-DRIVE&#...

Long Term Comparison between Liquid and Tablet Formulations of L-Thyroxine (L-T4) in the Treatment of Congenital Hypothyroidism (CH)

Introduction: Few studies have been published comparing the liquid and tablet formulations of L-T4 in pediatric patients, with a short follow-up period. Both formulations seemed to produce a rapid normalization of thyroid fuction with a tendency of a greater TSH inhibition in children taking the L-T4 liquid drops. The aim of our study is to compare the long-term effectiveness and saftey of both liquid and tablet L-T4 therapy in CH patients up to 3 years old via a multicenter s...

Background: Hashimoto’s thyroiditis (HT) has been linked to papillary cancer in adults but not in children and adolescents. Moreover, there is no agreement on the more appropriate frequency of thyroid ultrasound (TS) in the follow-up of children with HT.Objective and hypotheses: The aim of the study was to investigate the incidence of thyroid nodules and of thyroid cancer in a large group of children and adolescents (567) with HT followed-up for a m...
