Background: There is evidence that baseline and peak cortisol response to the low dose short Synacthen test (LDSST) varies with pubertal status and gender in children with asthma on inhaled corticosteroids. There are no published data reporting effects of puberty on cortisol response to the insulin tolerance test (ITT) in childhood and adolescence.Objective and hypotheses: To determine whether pubertal status, age or gender influence basal and peak corti...

Background: Donohue syndrome (DS) is the most severe form of insulin-resistance due to autosomal recessive mutations in the insulin receptor gene. Typical features include pre-/postnatal growth impairment, hyperinsulinaemic hyperglycaemia with fasting hypoglycaemia, nephrocalcinosis, recurrent sepsis, little adipose tissue, soft tissue overgrowth, hirsutism, acanthosis nigricans and facial dysmorphism. However, additional comorbidities may be present, affecting prognosis.<...

Objective: To evaluate musculoskeletal development using pQCT in children with coeliac disease (CD) on gluten free diet (GFD) compared with age and gender matched healthy controls.Method: Prospective cross sectional study. 38 children (18 males) with CD on GFD for a duration of 3.6 years (0.6, 12.5) and 38 age and sex matched healthy controls underwent pQCT at 4, 38 and 66% tibial sites. Bloods were collected in CD children only. Results reported as medi...

Background: Donohue syndrome (DS) is the most severe form of insulin-resistance due to autosomal recessive mutations in the insulin receptor gene. Previous reports demonstrate a role for recombinant human IGF1 (rhIGF1), however optimal treatment strategy remains unclear.Case series: Four males with DS have been treated with bolus rhIGF1 (see table below). They had no IGF1 response on an IGF1 generation test. No long-term side effects of rhIGF1 were repor...

Background: A disease of the immune system, responsible for 95% of cases of hyperthyroidism in children is very rare at this age, it affects one child in 10 million.Presentation: Khadija 3 year old girl admitted for goiter, no goitrogenic substances No drug Shot, No Inbreeding, goiter paternal aunt, The trouble was in the beginning 1 year a height and weight advance:+1 DS weight, height+3.2 DS, weakness, weight loss, Profuse sweating, tachycardia, irrita...

Introduction: Noonan syndrome (NS) is caused by mutations in RAS/MAPK signaling pathway genes. About 70% of the NS patients have short stature, and human recombinant growth hormone (rhGH) is an established yet not fully standardized treatment.Objective: To assess the first 2 years rhGH treatment effectiveness in NS patients at a single centre.Materials and methods: A total of 20 (16 male) NS patien...

Background: Adults with CF show a higher rate of osteoporosis compared to healthy adults. Achieving proper bone mass is a process starting in childhood. We aimed to evaluate the prevalence of decreased bone mineral density (BMD), changes during puberty and risk factors for low BMD in children and adolescences with CF in a large Dutch cohort.Patients and methods: A retrospective observational cohort study was performed in...

Background: Genetic factors play an important key role in regulating the timing of puberty. The premature activation of pulsatile release of gonadotropin-releasing hormone(GnRH) before 8 and 9 years of age in girls and boys causes central precocious puberty(CPP). Pathogenic variants in DLK1 are associated with isolated familial CPP. Here, we report three siblings with a diagnosis of CPP with novel variant in DLK1.Case Report:</st...

Background: Disorders of sex development (DSD) vary phenotypically and are caused by a number of genetic etiologies. Although several genetic abnormalities have been discovered through genetic analyses, the underlying genetic causes of 46, XY DSD remain unknown in most of the casesAim: To identify genetic defects in patients with 46,XY DSD.Material and Methods: A total 76 DSD patie...

Background: Disorders of sex development (DSD) are a heterogeneous group of disorders related to sex determination and differentiation. Although several genetic abnormalities have been discovered through genetic analyses, the underlying genetic causes of 30–40% of the 46,XY DSD cases are not yet known.Aim: To identify genetic defects in patients with 46,XY DSD.Material and methods: Seventy-six patients with 46,XY DSD were stud...
