Background/Aim: Currently, the minimum of the GH peak (pGH) to GH provocative stimuli, including the glucagon stimulation test (GST), has been arbitrary set in children at 7 µg/L, irrespective of gender and age. Several doses (fixed or per bodyweight) and ways of administration (IM or SC) of glucagon are being used in daily practice. This retrospective study explores the influence of gender, age, and adiposity on the pGH after a maximally effective glucag...

Background: A one-month-old girl was referred to our unit for osteogenesis imperfecta (OI). She was the first child of non consanguineous parents. The father had no history of fracture. The mother, 28 years-old, presented with a severe OI, short adult height (140 cm), moderate scoliosis. She had more than 20 limb fractures, no vertebral fracture and bowing limbs without need of surgery. She received Bisphosphonates during 3 years until 12 years of age. Then sh...

Obese children are at risk for increased DHEAS production, which is assumed to arise from hyperinsulinemia, hyperleptinemia, increased IGF-1 production or chronic low grade inflammation. Exaggerated adrenarche is suspected to be a forerunner of polycystic ovary syndrome in girls, but its consequences in obese boys are less well studied. In this study we evaluated the presence of exaggerated adrenarche in a cohort of obese boys and girls and investigated whether obese children ...

Objective: Premature GH treatment discontinuation of SGA is usually linked to safety or ineffectiveness. However, this population is poorly addressed compared to those with final adult height (FAH). Authors investigated the journey of SGA prematurely discontinued Norditropin® treatment in a French real-life.Methods: Observational prospective ongoing study: 291 Norditropin®-treated SGA. Annual FU up to FAH. Descriptive anal...

Objective: Age and height at treatment start, target height, GH dose, and first year treatment response are among known criteria of GH deficiency (GHD) good responders (final adult height [FAH] >−2 standard deviation score [S.D.S.]) to GH treatment (GHT). The authors investigated whether the same criteria are applicable to SGA patients based on real-life ongoing French registry data.Methods: 291 SGA children treated with Norditro...

Objective: Bang et al. showed that Δ height and growth velocity (GV) the first year of treatment could be predictive factors of statural response in SGA (n=54). Poor responders showed GV <1SDS (55%) and Δ height <0.5SDS (45%). Moreover, Ortego et al. seems to confirm the suitability interest of KIGS mathematical model in a retrospective SGA cohort (n=103) showing that the percentage of good responders in the first year varies betwee...

Background: Monogenic diabetes (MD) remains undiagnosed in more than 90% of the cases. However, precise, quick and cost-effective diagnosis is important to choose an adequate treatment and to avoid long-term complications.Objective and hypotheses: To develop and validate a diagnostic tool to improve diagnosis rate of MD in Switzerland, as well as to open new research directions.Method: Targeted next-generation sequencing (NGS) of 3...

Background: A diagnosis of diabetes in children used to mean type 1 diabetes (T1D) and lifelong insulin therapy. However, over the last decades the spectrum of diabetes has widened and even if auto immunity remains the most prevalent etiology, confounding factors and overlap with other causes of diabetes types sometimes make a revision of the initial diagnosis necessary.Objective and hypotheses: To classify diabetes etiologies in youth with diabetes usin...

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: Patients with Klinefelter syndrome (KS) have an increased risk for osteoporosis and fractures in adulthood. Data on bone mineralization in adolescence are limited, although it is a known at-risk period for vitamin D deficiency, low calcium intake and evolving hypogonadism.Objective and hypotheses: To study the bone mineralization in KS adolescents and its relationship with vitamin D/calcium and gonadal status. KS adolescents with low calcium ...
