Background: Premature thelarche (PT) may evolve into precocious puberty (PP). The incidence of PP in girls has increased during the last two decades. The epidemiology of PT in the first years of life is less well described.Objective and hypotheses: We aimed to identify 0–6 year old girls referred to paediatric evaluation for PT in order to examine if the number of girls with PT is increasing, and to describe clinical characteristics of the girls wit...

Background: Premature thelarche and precocious puberty are frequently diagnosed even in girls below 6 years of age. A GnRH test is often included in the diagnostic work up. Interpretation of the GnRH test in girls below 6 years of age is, however, difficult, because the reference interval has not been established in this age group.Objective and hypotheses: To establish the normal endocrine response to a GnRH test in healthy girls below 6 years of age.</p...

Background: The female gonadal axis is activated in mini-puberty and thereafter it is quiescent until puberty. We have shown that many girls with no clinical sign of puberty in the age group 1-6 yr. have a rather strong luteinizing hormone (LH) and follicle stimulating hormone (FSH) response to a gonadotropin releasing hormone (GnRH) test. However, stimulated LH and FSH values decreased in the age interval 1-6 yr and no LH/FSH values rose above 0.43. Serum est...

Daily injections are required for human growth hormone (GH) replacement therapy. Somapacitan is a long-acting GH derivative being developed for once-weekly dosing in adults and children using a proven protraction method, currently successfully in use to extend the half-life of insulin and glucagon-like peptide 1.To evaluate the efficacy and safety of three different once-weekly somapacitan doses compared with Norditropin®, a daily GH, ove...

Background: Somapacitan is a reversible albumin-binding growth hormone (GH) derivative in clinical development for once-weekly administration in patients with GH deficiency (GHD). Clinical data in healthy subjects, and adults and children with GHD showed that once-weekly somapacitan injections were well tolerated with no clinically significant safety or local tolerability issues. A sustained dose-dependent IGF-I response supports a once-weekly treatment regimen.<p class="a...

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: Central precocious puberty (CPP) is a common condition in girls and has been associated with deterioration of final height (FH). Height prognosis (HP) is critical for the decision of treatment in CPP. There are several methods for predicting FH in CPP but none is completely reliable. Most methods consider bone age (BA), which is very imprecise, but there is no consensus on which method is the best to estimate FH.Objective: To compare the accu...

Purpose: The aim of the present study was to determine the efficiency of three different predictive models [Bayley-Pinneau (BP), Roche-Wainer-Thissen (RWT), and Tanner-Whitehouse 2 (TW2)] by comparing their predictions with near-adult height (NAH) data of girls who received gonadotropin-releasing hormone agonist (GnRHa) therapy.Methods: Clinical findings were retrospectively analyzed. Bone age (BA) was determined by thre...

Introduction: One of the factors affecting the treatment decision in early puberty is bone age (BA) evaluation and adult height prediction (AHP), accordingly. These calculations have certain limitations. In this study, we aimed to compare the AHP results calculated by Bayley-Pinneau (BP) and Roche-Wainer-Thissen(RWT) methods based on BA evaluation by using Greulich-Pyle(GP) atlas and BoneXpert™ software.Methods: A t...

Introduction: In cases of precocious puberty, an important factor in making treatment decisions is when adult height estimates based on bone age (BA) determination are behind midparental height. In Turkey, clinicians often use the Greulich Pyle (GP) atlas to determine BA, which can lead to significant differences between assessors. The aim of this study was to compare estimated adult height (EAH) calculations based on BA determined by the automated BoneXpert m...
