Background: Normal function of the thyroid gland is essential for adequate neurological development of the fetus and child. In previous studies, associations between reduced birth weight and overt maternal and fetal thyroid dysfunction have been described. We hypothesize that also variations within the normal range of fetal thyroid function have an impact on fetal and neonatal growth.Objective: The aim of this study is to investigate whether thyroid horm...

Introduction: Vitamin D resistant rickets type II (VDDR-II) is a disease with a difficult treatment developed as a result of mutations in VDR gene. Despite high dose active vitamin D and oral calcium treatments, sufficient recovery cannot be achieved mostly. Successful results with intravenous calcium infusion that is an alternative treatment have been reported; however, serious restrictions and complications such as hospitalization, catheter infection, thrombosis, skin necros...

Background: Women with Turner syndrome (TS) are known to be at risk of osteoporosis and fracture. While childhood GH treatment is common in TS, the impact of this therapy on bone health has been poorly understood.Objective: The purpose of this study was to determine the effect of childhood GH-treatment on adult bone quality in TS women using dual X-ray absorptiometry (DXA) and high resolution peripheral quantitative computed tomography (HR-pQCT).<p c...

Introduction: Complications are frequently reported post hypospadias repair and there is a need to understand the factors that influence their occurrence.Aim: The aim of this study was to identify the occurrence of complications in boys with hypospadias that are in the I-DSD Registry.Methods: Data from boys born with hypospadias between 2010-2020 were obtained from the I-DSD regist...

Objective: This project aims to evaluate the effect of two isotopically labelled internal standards on the quantification of 17OHP by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) as an orthogonal technique.Methods: Three LC-MS/MS and one GC-MS/MS laboratories, spanning four countries worldwide, who routinely measure serum17OHP, compared two internal ...

Introduction: Patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) have specific plasma and urinary steroid patterns, with 11-oxygenatedC19 steroids established as key adrenal-specific androgens. Monitoring glucocorticoid (GC) replacement remains a challenge in the absence of reliable biomarkers.Aim: To reassess the urinary steroid profile of children with CAH in relation to plasma ...

Introduction: Growth hormone (GH) exerts its effect through insulin-like growth factor 1 (IGF-I), an intracellular signalling molecule whose production is stimulated by STAT-5b after binding to the growth hormone receptor. STAT-5b deficiency, is characterized by short stature, immune dysregulation and chronic lung disease. And these occur as a result of disruption of the growth hormone axis. Our case is an example of STAT-5b gene mutation, which is a rare dise...

Introduction: X-linked hypophosphatemia or XLH is a rare genetic disease, often revealed in children by rickets, growth failure, delayed walking, and leg bowing. Clinically the severity is reflected by leg deformities. The aim of our study was to assess the clinical and biochemical parameters correlated to the severity of XLH at the end of growth.Materiel and methods: Monocentric retrospective study of patients treated with phosphate supplements and vita...

Objective: Most recent evidence from conducted in human and animal studies suggests that vitamin D has a potential role in the physiology of reproductive function in both genders. We investigate the role of vitamin D in male and female gonadal function at mini-puberty period with particular emphasis on production of sex steroids and gonadal peptide hormones. Additionaly, this study evaluated serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradio...
