Background: Child growth is a dynamic process and influenced by various environmental factors. When measured at short intervals, growth of healthy children shows certain characteristic patterns, which have rarely been studied, but are of great importance for clinical purposes. The study was approved by the Ethical Committee of the University of Potsdam.Aim: To see whether measurements of height using photographic display...

We are in an exciting and interesting time, when pediatricians and reproductive endocrinologists across the globe rise to the challenge of providing fertility services for people with a history of gonadotoxic diseases. Indeed, developments in numerous medical fields have improved long-term survival rates for many diseases that strike children and young adults. However, to survive is no longer enough. The emphasis is shifting, to enable people to live a life as normal as possib...

Background: Encephalopathy associated with autoimmune thyroid disease (EAATD) is very rare in pediatrics. Contributing factors include: Sudden change is thyroid levels, cerebral vasculitis,endothelial inflammation or immune complex deposition, global cerebral hypoperfusion, as well as cerebral tissue-specific autoimmunity.The case: A 16-year-old female was diagnosed with hyperthyroidism and treated with Radio Iodine Ablation (RIA). Her total T4 level was...

Background: Analysis of steroids by gas chromatography-mass spectrometry (GC-MS) defines a subject’s steroidal fingerprint. Here, we compare the steroidal fingerprints of obese children with or without liver disease to identify the ‘steroid metabolomic signature’ of childhood non-alcoholic fatty liver disease.Methods: Urinary samples of 85 children (43 girls) age 8.5–18.0 with obesity (BMI >97%) were quantified for 31 steroid meta...

Context: Analysis of steroids by gas chromatography – mass spectrometry (GC-MS) defines a subject’s ‘steroidal fingerprint’. Here, we clustered steroidal fingerprints to classify childhood obesity by ’steroid metabolomic signatures’.Methods: Urinary samples of 87 children (44 F) age 8.5–18.0 with obesity (BMI >97%) underwent solid phase extraction, enzymatic hydrolysis and derivatization. 31 steroids metabolites wer...

Aim of the Study: Cryptorchidism occurs more frequently in CF-children, and malformed epididymis was found more in cryptorchid boys with abrogated mini-puberty. Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) is transporter protein that acts as a chloride channel. Specifically, CFTR is associated with spermatogenesis and fertility.Patients and Methods: Testicular biopsies for histological and RNA analysis from...

Introduction: Propionic Acidaemia (PA), an organic acidaemia, is characterized by episodes of decompensation with severe metabolic acidosis and hyperammonaemia. PA is associated with low bone mineral density and osteoporosis. Hypocalcaemia is known to occur in 35-65% of decompensations, however the underlying pathophysiology remains unclear. PTH resistance has previously only been described in one case of hypocalcaemia in PA and we report the first use of ...

Background: Pseudohypoparathyroidism type 1b (PHP1b) is caused by epigenetic errors on the maternal GNAS allele at differentially methylated regions (DMRs) associated with exons A/B, XL, and NESP that lead to reduced production of Gαs transcripts most notably in the renal proximal tubule and thyroid follicular cells. Most PHP1b cases appear sporadically, few of which can be explained by paternal uniparental disomy involving chromosome 20q, leading to global methy...

Background: Graves’ disease therapy in young children may be challenging due to lack of therapy options. The safety of Radioiodine Ablation (RIA) has not been proven in children under age of 10 years. Propylthioracil (PTU) therapy has been linked to hepatic failure and became contraindicated in pediatrics.The case: A 6-year-old female was diagnosed with Graves ‘disease and treated with Methimazole (MTZ) and Propranolol. A few days after startin...

Introduction: Most testis expressed (TEX) genes are testis-specific and evolutionarily conserved and several studies have reported important roles of TEX11, TEX12, TEX14, TEX15 and TEX 101 in mammalian fertility. Retrotransposons are thought to be critical for the evolution of mammalian genomes. TEX19 functions in the post-translational regulation of L1 retrotransposons, which are involved in maintaining trans-generational genome stability. In boys with crypto...
