Background: Anti-islet autoantibodies are predictive and diagnostic markers for type 1 diabetes (T1D). The most frequently determined pancreatic autoantibodies in T1D are anti-glutamic acid decarboxilase (GAD), anti-tyrosine phosphatase (IA-2) and anti-insulin (AAI).Objective and hypotheses: To study whether the pancreatic autoimmunity profile influences the initial presentation of diabetes, its metabolic behaviour and the presence of other autoimmune di...

Background: Preservation of C-peptide is important and has become regarded a relevant endpoint as already a quite small residual C-peptide seems to be related to both less acute and late diabetes complications.Objective: To assess the residual C-peptide secretion in pediatric patient with T1D.Method: Cross-sectional study of 157 patients with T1D. We analyzed: age at diagnosis, age at time of study (years), sex, diabetes duration (...

Background: Ectopic ACTH syndrome is very rarely seen in infancy, usually occurring in older children.Case presentation: A female infant was born by Caesarean section (BW 4280 g) with congenital anal atresia and a large tumour surrounding the cross-tail region. CT imaging identified a heterogeneous pelvic mass (76×49×38 mm) below the sacrum. On day 1 of life, a sigmoid colostomy was established and at age 1 week, part of the tumour with the coc...

Background: Neonatal over-nutrition (NON) can have a long-term effects on energy homeostasis and some of these effects may be sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and cytokine levels throughout development and if these changes are sexually dimorphic. We hypothesised that the effects would be both age and sex dependant.Methods: At birth, Wistar rats wer...

Background: GH (rhGH) treatment improves adult height in GH deficient (GHD) patients. However, there are differences in short and long term responses to treatment between children with permanent deficit (PDGH) and those who present a transient deficit (TDGH) when reassessed at final height (FH).Objective and hypotheses: To evaluate the response to rhGH treatment in patients with PDGH or TDGH one year after initiating treatment and at FH when treatment wa...

Background: Heterozygous alterations of SHOX and its regulatory region PAR1 are identified in approximately 70% of Léri-Weill dyschondrosteosis and 2–5% of idiopathic short stature cases. Identification of a SHOX mutation enables GH treatment to be offered to the patient.Objective: To evaluate the clinical characteristics of seven patients with SHOX haploinsufficiency and their evolution.Method: Retrospective analysis of ...

Background: Since the publication of international growth charts by the World Health Organization (WHO) in 2006, the use of national growth charts for growth monitoring (GM) has been questioned.Objective and hypotheses: To evaluate the potential impact of using WHO vs. national growth charts on the performance of a clinical decision rule for detecting children with one of the target conditions of GM: GH deficiency (GHD).Method: In ...

Background: In industrialised countries, the main goal of growth monitoring (GM) of apparently healthy children is the early detection of severe underlying conditions. However, empirical evidence suggests globally poor performances of GM, with important diagnosis delays for priority target conditions and many unnecessary referrals for diagnostic work-up for disease-free children.Objective and hypotheses: To evaluate and to compare the performance for ear...

Background: Hypothalamic hamartomas(HH)-rare heterotopic congenital malformations (incidence 1:200 000)-present with central precocious puberty (CPP) or gelastic seizures (GS) but their natural history and best treatment strategy are unknown. Given their proximity to the hypothalamus–pituitary axis, wider endocrine dysfunction may be expected.Objective and hypotheses: To describe clinical features and any evolving endocrinopathies in HH patients, by...

Background: Patients with 21-Hydroxylase deficiency (21OHD) present increased levels of cytochrome P450 21-hydroxylase substrates, like progesterone and 17α-hydroxyprogesterone. Previous studies could show that these hormones are involved in the production of androgens via the backdoor pathway. As a second source of androgens, 11-oxyandrogens derived from the human adrenal glands are recognized as being major androgens. Specifically, 11-oxyandrogens ...
