Background: Adrenal insufficiency in children is rare and potentially serious because of the risk of acute adrenal insufficiency. This complication is lethal in the absence of prompt and appropriate treatment. Aetiologies are dominated by the genetic causes.Objective and hypotheses: Report diagnostic circumstances,phenotypic forms and causes of adrenal insufficiency in children and adolescents.Method: This is a retrospective study ...

Introduction: Monogenic Type 1 diabetes (T1D) is a rare disease caused by pathogenic variant in a single gene leading to dysregulation of immune system. T1D is combined with other autoimmunity like immune cytopenias, inflammatory bowel disease, rheumatoid arthritis, atopic eczema, autoimmune thyroid disease etc in these patients. Pathogenic variants in the AIRE, FOXP3, LRBA, IL2RA, CTLA4, STAT3 and STAT1 genes have...

Objective: IGF-1 receptor mutations (IGF1RM) are a rare abnormality; however, affected patients exhibit severe postnatal growth retardations without catch-up growth. Although several cases of IGF1RM have been described, a comprehensive retrospective analysis of the potential benefit of rhGH treatment is still missing. The aim of this study was therefore to investigate baseline auxology, response to rhGH therapy and potential metabolic effects in patients with IGF1RM in compari...

Introduction: The National Registry of Civil Status through circular 33 of February 24, 2015 instructed the guidelines for the allocation of a sex through an inscription on the Civil Registry of Birth for intersexual minors.Objective: To create clinical and medical awareness on the importance of making an accurate diagnosis of Congenital Adrenal Hyperplasia CAH in order to avoid adverse effects due the omission of the due diligence by violating of the pr...

Background: The increasing number of transgender adolescents presenting in early puberty requires to investigate the effects of long-term puberty suppression and gender-affirming hormones (GAH) on body composition and metabolism. Clinical studies have ethical and practical limitations. A preclinical mouse model may be helpful to gain mechanistic insights.Methods: Prepubertal (4week-old) female mice were treated with the ...

Background: Transgender individuals increasingly present at gender services in childhood. Consequently, to suppress pubertal development, more adolescents are long-term exposed to gonadotropin-releasing hormone analogues (GnRHa), from onset of puberty until start of gender-affirming hormones (GAH), around 16 years. Prolonged GnRHa may compromise bone health more than shorter-term treatment. If earlier start of GAH, when psychologically indicated, may partially...

Although widely prescribed for their anti-inflammatory and immunosuppressive properties, glucocorticoids have various common metabolic side effects including hypertension, dysglycemia, and diabetes. Proposed risk factors for steroid-induced dysglycemia and metabolic syndrome include cumulative dose, longer duration of steroid course, and high body mass index.Aim: This study was carried out to investigate the prevalence of different metab...

Background: Kabuki syndrome (KS) is a rare multiple congenital malformation and intellectual disability syndrome. KS is caused by pathogenic variants in the genes KMT2D or KDM6A. In 0.3-4% of patients, KS is reported to be associated with hyperinsulinemic hypoglycemia. The objective of this study was to characterize the clinical, biochemical and molecular data of children with KS and hyperinsulinemic hypoglycemia.<s...

Introduction: Early puberty is defined in the girl by the appearance of secondary sexual characteristics before the age of 8 years. Unlike the boy, the central origin is most often idiopathic. The familial nature encourages looking for a genetic mutation which can explain this early maturation of the gonadotropic axis.Cases: These are three girls from a consanguineous marriage. They had no particular pathological anteced...

Background: Non-idiopathic central precocious puberty (CPP) is caused by acquired or congenital hypothalamic lesions visible on magnetic resonance imaging (MRI), or associated with various complex genetic and/or syndromic disorders without visible lesions on MRI. We investigated the different types and prevalences of non-isolated CPP phenotypes in a large group of consecutive patients with CPP.Methods: This observational cohort study included all patient...
