Background: The iNCGS Registry monitored long-term safety and effectiveness of NutropinAq® (Somatropin injection) for paediatric growth disorders.Objective: To report year-1 effectiveness and safety data from the iNCGS registry (NCT00455728).Methods: Open-label, non-interventional, post-marketing surveillance study, in seven European countries from October 2005–December 2016. Measurements included height Standa...

The genomic analysis of 46,XX individuals with testes (known as testicular Disorders/Differences of Sex Development (TDSD) or ovotestes (ovotesticular DSD (OTDSD)) supports the hypothesis that ‘pro-testis/anti-ovary’ or ‘pro-ovary/anti-testis’ genetic pathways exist. These children typically present with virilized genitalia due to testosterone production from the presence of testicular tissue. Many individuals with TDSD and a minority with OTDSD have a tran...

Background: 46,XX DSD (Disorder of Sex Development) includes individuals with ovotestes (ovotesticular DSD (OTDSD)) or testes (testicular DSD (TDSD)). Most individuals with 46,XX TDSD carry the SRY gene. Other known causes of TDSD/OTDSD include chromosomal rearrangements involving SOX9 or SOX3 and mutations of WNT4 and a WNT regulator, R-SPONDIN 1. However, our understanding of the molecular causes of TDSD and OTDSD remain incomplete.<p ...

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: Neonatal Cushing syndrome is a rare and severe condition, mostly associated with the McCune-Albright (MCA) syndrome. Management options include medical treatment (with ketoconazole or metyrapone resulting in 11-beta-hydroxylase blockade) and radical treatment with bilateral adrenalectomy. Spontaneous regression in late infancy has been reported.Objective and hypotheses: To report on the outcome of a 14 month-old girl with severe neonatal Cush...

Background: RePPOP Aquitaine (network of prevention and treatment of pediatric obesity in southwest France) has developed a multidisciplinary approach to treat childhood obesity based on multicomponent lifestyle interventions and family-based actions.Objective and hypotheses: This study assessed the impact of the care management proposed by RePPOP Aquitaine and investigated factors associated with better outcomes.Method: The impact...

Background: Prader–Willi syndrome (PWS) patients have been followed in our country in different ways but without a reference center. In January 2015, we started a PWS reference center in Sao Paulo University to promote a better care for patients and families and to support them with a multidisciplinary team, including pediatric endocrinologist, dietician, nurses, neurologist specialized in sleep disorders and otorhinolaringologist.Method: Forty-two ...

Background: Hyponatremia is one of the most common electrolyte disorders in hospitalized children and early diagnosis and management are crucial to prevent morbidity and mortality. Because of the physiological resistance to aldosterone under 3 months of age, the mechanisms leading to hyponatremia are often misunderstood.Objective and hypotheses: To assess the prevalence of hyponatremia in hospitalized infants younger than 100 days and evaluate the mechan...

Background: Difficulties in transition of adolescent Turner Syndrome (TS) patients to adult health care has been reported in many studies.Objective and hypotheses: We conducted a medical and psychological follow-up of adult patients with Turner Syndrome which had been treated at our tertiary pediatric endocrine centre.Method: We screened for expected comorbidities and provided a questionnaire asking for current medical care. Furthe...

Background: Pseudohypoparathyroidism (PHP) is characterized by proximal tubular resistance to PTH and, in some disease variants, by Albright osteodystrophy. PHP is caused either by mutations in those regions of GNAS encoding Gsα (PHP1A and PseudoPHP) or by GNAS methylation defects (autosomal dominant (AD) and sporadic (spor) PHP1B). Phenotypic differences in fetal growth, post-natal growth and metabolism are observed in the different PHP types.<p cla...
