Background: Short stature is a main feature of Noonan syndrome (NS). Although rhGH is commonly used in NS patients, it is not known whether a defect in the secretion of GH influences the response to rhGH therapy.Objective and hypotheses: The aim of this study was to evaluate the efficacy and safety of rhGH treatment in NS patients, according to the presence of GH deficiency at the baseline.Method: We retrospectively collected data ...

Background: Collaborative project to review the phenotypic and genotypic data from children recruited to the UK wide deciphering developmental disorders (DDD) study.Objective and hypotheses: To report the frequency and range of disorders of sex development (DSD) phenotypes observed in DDD participants who have one or more associated ‘neurodevelopmental delay’ diagnostic human phenotype ontology (HPO) term.Method: Retrospe...

Background: Thyroid disorders (subclinical hypothyroidism and structural abnormalities) are common in Williams syndrome (WS) patients.Objective and hypotheses: Central hypothyroidism and GH deficiency (GHD) in a WS patient are discussed.Method: Case report and literature review.Results: A 5-month-old male was admitted to our hospital because of growth failure since the 3rd month, mild dysmorphisms, micropenis...

Introduction: Laron Syndrome (LS) or primary growth hormone (GH) insensitivity is an autosomal recessive disorder due to variants in the GH-receptor (GHR) gene or to post-receptor defects. LS prevalence is estimated 1-9/1000000. We report a case of LS with a missense variant in the GHR gene not previously described.Case: female, Turkish, was referred to our clinic for short stature. Born at term, birth ...

We present the case of a now 20 months old female patient, in whom we diagnosed MAS on the basis of pseudoprecocious puberty and hypercorticism at the age of 10 months. Medical history and photodocumentation suggested that symptoms of hypercorticism were present soon after birth. At age 4 months thelarche had occurred, followed by vaginal bleeding at age 5 months. At first presentation at our outpatient clinic, the girl was severely short (-5 SDS), with only minimally advanced...

Purpose: Clinical problems caused by impaired molecular function of inborn errors of immunity (IEI) genes are not limited to the immunological system but can also affect the endocrine system. An autosomal recessive form of severe congenital neutropenia also known as Kostmann syndrome (KS) is caused by mutations in the gene encoding the mitochondrial protein HAX1. Knowing that most endocrine disorders associated with IEI are hypofunction, a close cooperation be...

Introduction: Longitudinal skeletal growth is achieved by enchondral ossification in epiphyseal growth plates (GP) of long bones and vertebrae. These highly organized cartilaginous tissues contain chondrocytes of all differentiational stages classified in three distinct zones named resting, proliferative and hypertrophic. Separated analysis of individual zones is essential in basic GP research thus efficiency of different zonal separation methods confers high ...

Objective: Young women with Turner syndrome are known to be especially at risk for lost of follow-up. Recent literature indicates that there are disparities regarding transition readiness between different chronic conditions. To assess differences in transition readiness might be crucial for identifying special needs in specific patient cohorts when preparing for transfer to adult care. Our hypothesis was, that young women with Turner syndrome would score lowe...

Context: Quality of survival (QoS) is frequently impaired in childhood-onset craniopharyngioma (CP) patients due to sequelae caused by the hypothalamic syndrome. The debate, whether primary hypothalamic involvement (HI) has apriori prognostic impact or surgical hypothalamic lesions (HL) determine outcome, is controversial. Accordingly, we analyzed, whether CP patients at high risk for hypothalamic obesity due to primary HI of anterior and posterior hypothalamic structures bene...

Background: Hyperphosphatemic conditions such as chronic kidney disease are associated with muscle wasting and impaired life quality. While muscle regeneration relies on myogenic progenitor recruitment, the effects of high phosphate loads on this process has not been investigated in detail. This study aims to clarify the direct effectsof hyperphosphatemic conditions on skeletal myoblast differentiation in an murine cell model system.Material and methods:...
