Background: Despite early detection and treatment, children with Congenital Hypothyroidism show subtle persisting deficits in various cognitive abilities. Degree and type of deficit reflect CH severity at time of diagnosis. We reported (Rovet et al., ATA, 2012) children with CH had abnormal cortical morphology, consistent with animal evidence showing early thyroid hormone (TH) insufficiency affects cortical development. It is not known, however, whether these cortical...

Background: There are a lot of reasons for missing the diagnosis in neonatal screening for congenital hypothyroidism (CH), but errors in processing samples and reporting results are the most frequent! In Central Serbia screening for CH was instituted in 1983 by determination of the TSH level in dried filter-paper blood spots. All samples are analyzed at one central laboratory. The average number of specimens that are annually screened is 50 000. The screening process was divid...

Background: The contribution of mutations in paired box domain (PAX8) gene in children with congenital hypothyroidism (CH) and thyroid dysgenesis (TD) still remains a subject of interest of researchers. While quantitative PCR and direct sequencing concentrate on single gene fragment analysis and identification of point mutations, multiplex ligation-dependent probe amplification (MLPA) analysis might improve the detection rate of PAX8 mutations in patients wit...

Background: Congenital hypopituitarism (CH) is a group of disorders characterized by deficiencies in one or more hypophyseal hormones and a marked variability in genotype-phenotype correlations. Central diabetes insipidus (DI) is caused by a decreased release of ADH and results in a variable degree of polyuria. Their association is normally found in congenital cerebral midline abnormalities, such as septo-optic dysplasia.Objectiv...

Of the several genetic defects responsible for thyroid dyshormonogenesis, mutations in TPO gene are the most prevalent causes of inherited defects in CH. Prevalent mutations are in exons 8-11 (catalytic site).Case presentation: Girl, born at 16d after term, before the introduction of the neonatal screening, with asphyxia, BL 55 cm, BW 4 kg. Because of insufficient weight gain, feeding difficulties, prolonged jaundice she was referred to a pediatric endoc...

Backgrounds: The prevalence of congenital malformations (CM) is higher in infants referred with capillary (c) TSH elevation on newborn screening. However, establishing the prevalence of CM ± dysmorphic syndromes in true congenital hypothyroidism (CH) requires careful distinction between true and transient CH.Objective: To determine the prevalence of CM ± dysmorphic syndromes in all infants referred with TSH elevation on newborn screening in Sco...

Background: As newborn screening test (NST) became popular, the incidence of congenital hypothyroidism (CH) was raised. But not all CH children require lifelong levothyroxine (LT4) replacement therapy.Objective and hypotheses: We aimed to analyse predicting factors suggesting transient CH (TCH) compared to permanent CH (PCH) or transient thyroid function test (TFT) abnormality who had a positive screening results in our centers for the past de...

Background: Congenital hypothyroidism (CH) occurs in 1:3000–1:4000 newborns. The majority of newborns with CH are detected by routine screening programs and treatment is promptly initiated following confirmatory thyroid function testing. Although early imaging studies do not influence the treatment decision or management, they establish the underlying diagnosis and may distinguish between permanent and transient CH.Objective: To assess the role of e...

Background: Congenital hypothyroidism (CH) is the most frequent endocrine disease in infants with prevalence ratio in the range of 1:2000–1:4000 new-borns. The disorder can be permanent (CHP) or transient (CHT). CH can be classified into two main groups: Dysgenesis, which accounts classically for 80–85% of cases and dyshormonogenesis for remaining 15–20%. From the last decade, studies described a upward trend for CH prevalence and changes in groups’ proport...

Background: It is reported that children with congenital hypothyroidism (CH) are at increased risk of developing childhood obesity. Moreover, it is known that the timing of adiposity rebound (AR) in childhood is strongly linked with future obesity. Aims of our study were to explore the timing of AR and to identify factors affecting AR in a cohort of children with CH diagnosed by newborn screening and treated with levothyroxine. Design: one-center, retrospectiv...
