Background: Neonatal TSH screening program for congenital hypothyroidism (CH) in Central Serbia was introduced in 1983. Over the past three decades, increasing overall incidence rate of children with both permanent and transient forms of CH has been observed.Objective and hypotheses: The aim of the study was to compare incidence of CH in the first 16 years of screening (period 1) with the last 15 years of screening (period 2). We also investigated the im...

Background: Levothyroxine monotherapy is the treatment of choice for congenital hypothyroidism (CH). Recently, it was reported that levothyroxine monotherapy cannot guarantee euthyroidism in all athyreotic adult patients. A more physiological treatment than levothyroxine monotherapy was suggested to be required in some patients with hypothyroidism.Objective and hypotheses: To elucidate whether levothyroxine monotherapy is appropriate for all children wit...

Background: A small subgroup of children with isolated growth hormone deficiency (IGHD) develop central hypothyroidism (CH) during GH treatment. Prognostic parameters are still unclear.Objective and hypothesis: Long-term evaluation of children with initial diagnosis of IGHD to identify those with an unmasking CH under GH treatment. IGHD was diagnosed in children with short stature, low height velocity, retarded bone age,...

Introduction: Data on BP in children with classic congenital adrenal hyperplasia (CAH) is inconsistent.Aim: To assess the trend in BP throughout childhood using data from the International CAH registry and compare this to normative data from the American Academy of Paediatrics (AAP).Method: This retrospective multi-centre study included 37 centres from 20 countries. BP data was ana...

Background: The incidence of congnenital hypothyroidism (CH) differs significantly among different ethnicity and regions, and early differentiation of transient CH is important to avoid unnecessary prolonged treatment with L-T4, it is also helpful for predicting prognosis and alleviating families’ psychological burden.Objective and hypotheses: To investigate the incidence of CH based on the newborn screening program in Guangxi Zhuang Autonomous Regi...

Aim of the study: The aim of this nationwide population-based register study was to investigate the incidence of congenital malformations, neonatal and chronic comorbidities, and the use of prescribed drugs in patients with primary congenital hypothyroidism (CH).Methods: The study cohort and matched controls were identified from national population-based registers in Finland (The Social Insurance Institution of Finland a...

Background: Neonatal screening is a preventive strategy for various endocrine, metabolic and genetic conditions. Congenital hypothyroidism (CH) is one of the most common preventable and treatable causes of intellectual disability, and delayed diagnosis can lead to disastrous consequences. Incidence of CH is1:3000-1:4000 neonates worldwide but data varies globally. Pakistan lacks a national newborn screening programme for any inherited disease, but Aga Khan Uni...

Background: Congenital hypothyroidism (CH) is a common and preventable cause of mental retardation in children, and is detected using dried blood spots in many neonatal screening programs. Upon suspicion of CH, plasma free thyroxine (FT4) and thyroid stimulating hormone (TSH) concentrations are measured. CH can be of thyroidal or central origin (CH-T and CH-C, respectively). While CH-T diagnosis is based on an elevated plasma TSH in combination with a low FT4,...

Background: Congenital hypothyroidism (CH) can be categorized into two types: transient CH (group T) and permanent CH (group P). Several studies have recently demonstrated that the levothyroxine (LT4) dosage is useful for predicting LT4 requirement; however, none of the studies followed up their patients to puberty.Objective: To determine the cutoff value for the LT4 dosage as a predictor of LT4 requirement after puberty...

Background: Recent studies have analyzed the influence of perfluoroalkylated substances – PFAS (in particular PFOS and PFOA) on people and thyroid. Children are primaly affected by these pollutants. On the other side variation of incidence of congenital hypothyroidism (CH) has been shown in recent years by different studies. We sought to determine whether the incidence of CH in north-eastern Italy has changed in relation to some endocrine disruptors and t...
