Background: Optimisation of hydrocortisone replacement therapy remains challenging due to complex pharmacokinetics as circulating cortisol is protein bound mainly to corticosteroid-binding globulin (CBG) that has a circadian rhythm.Objective: A detailed analysis of the CBG circadian rhythm and its impact on cortisol exposure during hydrocortisone replacement therapy.Methods: CBG was measured over 24 h in 14 healthy...

Background: Among their metabolic effects, GH and its mediator IGF1 have been reported to influence hematopoiesis. Indeed, GH/IGF1 axis promotes erythropoiesis and GH deficiency (GHD) has been associated with a normochromic and normocytic anemia both in adults and in children. In contrast, in vivo data on the effects of GH/IGF1 axis on leukocytes and platelets are scanty.Objective and hypotheses: To evaluate the effects of 4-years GH replacement...

Introduction: Congenital disorder of glycosylation type-1a is a multi-system disease involving neurological, gastrointestinal, ophthalmologic, cardiac or endocrine systems. In addition to hypothyroidism and hypergonadotropic hypogonadism, rare occurrences of hyperinsulinemic hypoglycemia in CDG patients have been reported. In the present report, we describe a patient diagnosed with CDG type-1a accompanied by hyperinsulinemic hypoglycemia, and whose responsive to diazoxide....

Background: Between the 6000 monogenic disorders, only few are due to a single mutation. Recently, a specific mutation has been described in TUBB3, encoding tubulin beta 3, in the association of Moebius syndrome (MS) and Kallmann syndrome (KS). MS is a congenital paralysis of eye and face’s muscles and can be caused by mutations of TUBB3. KS combines hypogonadotropic hypogonadism and anosmia.Objective and hypotheses: The combination of these two syn...

Deletions at 16p11.2 have been reported to be associated with obesity, intellectual disability and various malformations. There are variations in phenotypes associated with deletions of different sizes in this region. Some deletions encompass the SH2B1 gene encoding an adaptor protein involved in leptin and insulin signalling which is believed to be causal for the early-onset obesity of these patients who in addition show a developmental delay (see patient 1). Deletio...

Background: Hypoglycaemia is the most common and threatening complication in diabetic children. Nocturnal hypoglycaemia is mostly unrecognised and asymptomatic, but recurrent mild hypoglycaemia at night can lead to hypoglycaemia unawareness and reduced performance at daytime.Aims: To evaluate frequency and duration of nocturnal hypoglycaemia in type 1 diabetic children and to identify risk factors for such events.Patients/methods: ...

Background: CNS tumors are the most frequent solid tumors in pediatric population. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. Recently, we have shown that in paediatric gliomas, IGF-1R nuclear localization was significantly associated with both high grade tumours and increased risk of death, suggesting that nuclear IGF-1R localization may contribute to an aggressive behaviour of these tumours.<p class="...

Background: Osteogenesis imperfecta (OI) is a genetic connective tissue disorder with variable phenotype, mainly characterized by bone fragility, short stature and non-skeleton findings. Since growth failure is a predominant feature of OI, recombinant human growth hormone (rhGH) has been suggested as a potential intervention. We describe two boys with OI type I treated with rhGH.Case Reports: Patient 1 had the first frac...

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: Childhood brain tumour survivors are at risk of developing endocrine secondary effects throughout lifetime. Transition between childhood and adult care is a critical moment during which patients may stop medical visits and treatments.Objective: To describe endocrine care transition in our cohort of patients with primary brain tumors followed from 2010-2015, who are ≥=18 years old by December 31st</...
