In a retrospective study (1), we found that a GH<6.5 μg/L, IGF-I-WHO87/518 <30 μg/L and IGFBP-3<0.8 μg/mL confirmed GHD diagnosis with high diagnostic accuracy in neonates with clinical suspicion of GHD. GH and insulin negatively regulate IGFBP-2, and it was proposed to reflect GH status in the diagnostic work-out of GHD in childhood and adults. The accuracy of IGFBP-2 has not been set for neonates.Objective: To prospectively v...

IGF2, a major actor which stimulates feta growth, is located within the imprinted 11p15 region, and 11p paternal duplications are usually associated with Beckwith Wiedemann syndrome, a rare condition usually associated with overgrowth. The IGF type 1 receptor binds both IGF-I and IGF-II to promotes cell proliferation and growth, and the IGF1R gene is located at chromosome 15q. Patients with deletions or mutations of IGF1R usually present with intraut...

I will review the latest developments in imaging of the brain using magnetic resonance. Over the last twenty years imaging of the diffusion of water molecules in the tissue has emerged as the method of choice for measuring the structure of brain tissue. The development of so called diffusion tensor imaging had allowed measurement of anisotropy which reflects how aligned or coherent is the underlying structure of myelinated axons in white matter. For example we have shown in ch...

Background: Turner syndrome (TS) can manifest with various clinical features depending on the karyotype and the genetic background of affected subjects.Objective and hypotheses: The aim of this study was to evaluate growth parameters from birth to adulthood in girls with TS in a cross-sectional study.Method: A total of 842 patients, with an age of diagnosis ranging from birth to 18 years followed-up between 1984 and 2014, from 35 d...

Background: Turner syndrome (TS) is characterised cytogenetically by X chromosome monosomy, the presence of an abnormal X chromosome, or mosaicism of a 45,X or have an abnormal sex chromosome rearrangement. Girls with variant TS show no features, fewer or milder features of TS.Objective and hypotheses: We are reporting on a clinical report of a girl with a rare variant of TS (46,X,i(X) (q10)).Method: This is a case report of a 12-y...

Aim: Osteogenesis imperfecta (OI) is a genetic disease of extracellular matrix presenting with varying degrees of skeletal fragility. The study aims to evaluate growth and pubertal characteristics of 83 patients with OI.Materials and methods: Patients were classified according to Sillence clinical classification criteria. Demographic data, clinical findings, growth and pubertal characteristics were recorded from medical charts, retrospec...

Background: Childhood onset PTC has a more aggressive presentation but no overall increase in mortality compared to adults.Objective: To characterize a pediatric cohort with PTC at diagnosis using the American Thyroid Association (ATA) Initial Risk Stratification (IRS) and to evaluate the response to initial treatment until 3 years based on the modified ATA Dynamic Risk Stratification (DRS) for adults.<p class="abste...

Magnetic resonance imaging (MRI) of the brain in disorders of sexual development (DSD) is still relatively scarce despite the opportunities it offers for understanding the influence of sex hormones on emotion and cognition. In this talk I will give an update on current structural and functional MRI research in different DSDs such as Klinefelter syndrome, Turner syndrome, Congenital Adrenal Hyperplasia, or Familial Male Precocious Puberty. Finally, parallels will be drawn to cu...

Thyroid hormone is crucial for metabolism and development. Cellular thyroid hormone homeostasis requires adequate function of (i) thyroid hormone transporter proteins, (ii) deiodinating enzymes and (iii) nuclear receptors. Thyroid hormone transporters are crucial for cellular uptake of T3 and T4. Over the last years, a number of thyroid hormone transporters have been identified and their physiological relevance has been established. The most well-studied example is MCT8 defici...

Background: Pre- and postnatal growth retardation of unknown pathogenesis is a common clinical feature in patients with Williams-Beuren syndrome (WBS). However, growth hormone deficiency (GHD) has not been considered a major cause of growth retardation.Case reports: We report two female patients with confirmed WBS who had defective GH secretion in response to two provocative tests and low IGF-I level and their growth response to GH therapy for 9 years. T...
