Female phenotype and sex reversal are often reported in 46,XY patients with 5α-Reductase Type 2 Deficiency (5αRD2). In case of late diagnosis, at puberty, virilization occurs. Over the years, sex assignment in case of early diagnosis evolved from female to male. We report four cases of 5αRD2, managed differently over three decades. All children presented with a female phenotype (EGS 3-4), palpable gonads, absent uterus, and 46,XY karyotype. All patients were ...

X-linked hypophosphatemia (XLH, MIM 307800) is a rare hereditary disorder of bone metabolism characterized by growth impairment, leading to bone deformities and short stature and beside others to muscle function deficits. XLH is caused by defect of endopeptidase PHEX leading to high levels of FGF-23 and thereby renal phosphate wasting. While conventional treatment includes substitution of phosphate and 1-25 OH-Vitamin D, now a treatment with a FGF-23 antibody (burosumab) is av...

Introduction: The Immune Thrombocytopenic Purpura (ITP) and Graves Disease (GD) have in common an autoinmune physiopathology. ITP is characterized by a platelet count less than 100 × 106/l in the absence of other cause. On one hand, ITP has been associated with thyroid dysfunction, without developing GD. On the other hand, GD might develop with moderate thrombocytopenia, generally more than 100×109/l. It is described that in most cases ITP might...

Background: Treatment of CAH in children is compromised by the pharmacokinetic of available hydrocortisone (HC) preparations resulting in un-physiological early morning rise of ACTH followed by elevated androgens. HC substitution usually follows a fixed dosing scheme (50%–25%–25%) monitored by blood sampling.Objective and hypotheses: We describe the individualized optimization of HC treatment by 17-OHP saliva profiles and the effects of the res...

Background: Osteogenesis imperfecta (OI) is a hereditary connective tissue disorder due to mutations related to collagen type 1. OI presents itself with low bone mass, resulting in high bone fragility. Bone mass is relevant for determination of the severity of OI. Although bisphosphonate treatment is able to increase areal bone mineral density (aBMD) measured by DXA, there is no correlation to fracture rates.Objective and hypotheses: The aim of this stud...

Background: NordiNet® IOS (NCT00960128), a non-interventional study, collects long-term effectiveness and safety data of GH (Norditropin®, Novo Nordisk) treatment in everyday clinical practice.Objective and hypotheses: Identify paediatric patients more likely to experience a second adverse event (AE).Method: Based on diagnosis at GH treatment start and associated risk for mortality, patients were cla...

Introduction: Osteogenesis imperfecta is a rare disease leading to immobility by recurrent fractures, hyperlaxicity of ligaments, short stature and muscular weakness. Beside drug treatment and surgical procedures physiotherapy is one of the most important treatment approaches to increase mobility. The objective of our analysis was to evaluate the effect of a new standardized 12 months physiotherapy concept including whole body vibration over 6 months on motor function and bone...

Introduction: Osteogenesis imperfecta (OI) is a hereditary disease characterized by a wide range of skeletal signs. Mutations in COL1A1/A2 have been known to cause dominant OI. Recently, a heterozygous mutation in the 5′-UTR of IFITM5 (c.−14C>T) was identified as a new cause of dominant OI. We present three patients from three different families with two mutations in IFITM5 with extremely different phenotypes.Description...

Background: Osteogenesis imperfecta (OI) is a rare disease leading to an increased bone fragility due to a reduced bone mass. Pathological fractures are the most severe symptom. More than 85% of patients are affected by mutations in COL1A1/A2 impairing quantity and quality of collagen. No approved drugs for OI treatment in childhood are available.Objective and hypotheses: A prospective pilot study was performed to assess safety and effi...

Background: Long-term safety data are reported for paediatric patients treated with recombinant GH (GH; Norditropin®, Novo Nordisk A/S) at the treating physician’s discretion and enrolled in the observational NordiNet® International Outcome Study (IOS) (NCT00960128).Objective and hypotheses: To evaluate incidence rates (IR) (events/1 000 patient-years) of adverse drug reactions (ADR), serious adverse events (SAE), and...
