Poland’s syndrome is characterised by unilateral absence or hypoplasia of the pectoralis muscle, associated with the ipsilateral malformation of the hand. The syndrome is usually sporadic and occurs in about 1:32.000 live births. Poland’s syndrome has been described associated with other abnormalities, including renal aplasia or hypoplasia, hemivertebra, Klippel-Feil syndrome and Moebius’ syndrome. In literature are reported six cases of Moebius syndrome associa...

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) results from gain-of-function mutations in the AVPR2 gene coding for vasopressin receptor 2 (V2R). In contrast, nephrogenic diabetes insipidus (NDI) is caused by loss-of-function mutations in AVPR2. Here we describe and functionally characterize a novel mutation located in the seventh transmembrane domain of V2R. This mutation was identified in a boy suffering from water-induced hyponatrem...

Objective: Re-testing of childhood-onset GHD needs discontinuation of GH treatment at near-adult height. We recently reported significant changes of body composition as a consequence of severe GHD during this time period.Aim: Does a 6 month interruption of GH treatment decrease bone quality significantly in patients with severe GHD of adolescence?Patients and Methods: In 90 patient...

Objectives: PATRO Children is a non-interventional, international, longitudinal study of the long-term safety of a recombinant human growth hormone (rhGH; Omnitrope®, Sandoz). In particular, the study will assess the diabetogenic potential of rhGH and the risk of malignancies. The long-term efficacy is a secondary objective of the study.Methods: The study population includes infants, children and adolescents receiving Omnitrope®...

Background: Pharmacologic options for treatment of osteolytic diseases especially in children are limited. Although not licensed for use, denosumab, a fully humanized antibody to RANKL, is used in children and shows good effects. Among others, one indication are giant cell tumors of the bone. Yet, there are reports of severe hypercalcemia after stop of denosumab, an adverse effect which is rarely seen in adults.Case reports: Four patients, aged 6, 13 and...

Amiodarone induced hyperthyroidism is a known side effect of amiodarone treatment. In the pediatric population long-term amiodarone treatment is rarely indicated because of its severe side effects including thyroid function impairment and therefore treatment is restricted to therapy resistant arrhythmias. In the literature scarce data is available on management and therapy of amiodarone induced thyroid dysfunction at a young age. We present three adolescent patients developin...

Background: Beckwith-Wiedemann Syndrome (BWS) is a rare overgrowth disorder secondary to various mutations in growth-regulatory genes on chromosome 11p15.5. A well-established association exists between BWS and both benign and malignant tumours, most commonly Wilms’ tumour and hepatoblastoma. We present a less frequently described diagnosis of bilateral phaeochromocytoma in association with BWS.Case report: We report the case of a 14-year-old girl w...

Background: PATRO Children is an international, open, longitudinal, non-interventional study of the long-term safety and efficacy of Omnitrope®, a biosimilar recombinant human GH (rhGH).Objective and hypotheses: The primary objective of PATRO Children is to assess long-term safety of Omnitrope® (particularly the diabetogenic potential of GH in short children born small for gestational age, the risk of malignancies, and oth...

Background: Silver-Russell syndrome (SRS) is a heterogeneous condition characterized by intrauterine growth restriction, relative macrocephaly at birth, postnatal growth retardation, body asymmetry, feeding difficulties/ low body mass index and dysmorphic craniofacial features. SRS is caused by DNA hypomethylation at the H19/IGF2-imprinting control region (ICR1) on chromosome 11p15 or maternal uniparental disomy of chromosome 7 (mUPD7) in approximately 50% and 10%, respectivel...

Background: Butyrate is a short-chain fatty acid closely related to the ketone body β-hydroxybutyrate (BHB) considered as the major source of energy during prolonged exercise. During fasting, when the liver switches to fatty acid oxidation, a rise in serum GH occurs concomitantly with the accumulation of BHB and short chain fatty acids (SCFA) acetate, propionate and butyrate. Interactions between GH, ketone body and SCFA during the metabolic adaptation to fasting are poor...
