Background: To the best of our knowledge, no study has been conducted to assess the impact of 21 hydroxylase deficiency and hidrocortisone treatment on electrocardiographic measures in children with 21-hydroxylase-deficient congenital adrenal hyperplasia.Objective and hypotheses: The purpose of this study is to compare the12-lead electrocardiographic measures such as PWd, QT interval, QTd, Tp-e interval, Tp-e/QT and Tp-e/QTc ratio in patients of 21-hydro...

Background: There is limited knowledge about the natural history of growth in patients with congenital hyperinsulinism (CHI). The disease itself, as well as its treatment methods with common long-term sequalae in terms of pancreatic endocrine and exocrine dysfunction have the potential to affect growth. We investigated longitudinal height growth of CHI patients in a large Finnish cohort.Materials and methods: In this cro...

Background: Since the first description of inactivating PTH/PTHrP signaling disorders [(iPPSD, former pseudohypoparathyroidism (PHP)] a remarkable clinical variability was observed, apparently age-dependent. The main clinical features, including PTH resistance, brachydactyly and short stature, develop during middle and late childhood. Hearing loss (HL) is commonly found in iPPSD/PHP. Only a few studies approached the subject of hearing loss in iPPSD/PHP and th...

Introduction: The EOSS is a clinical tool to assess the burden of obesity and has been shown in adults to predict later morbidity and mortality. We found that the pediatric version (EOSS-P) appears to predict later cardiometabolic outcomes, however whether it is a better predictor than anthropometrics alone remains unclear.Objectives: To compare associations between EOSS-P stage at 8-10 years and cardiometabolic outcomes...

Introduction: 46,XX testis/ovotesticular (OT) disorders of sex development (DSD) are rare conditions where gonadal differentiation in 46,XX individuals leads towards testicular development. SRY-negative 46,XX OT-DSD is even rarer compared to other DSDs.Case Presentation: A male patient presented at the age of 3 due to micropenis. Physical examination revealed penile hypospadias and bifid scrotum; phallus length was 2.2 c...

Introduction: Neurotensin is a 13 amino acid peptide with central and intestinal effects. It has been shown to decrease intestinal and gastric motility, increase the absorption of fat by regulating the release of pancreas and bile acid. In addition, it is reported that there is also an anorexigenic effect of the neurotensin released from the central nervous system. In the literature, conflicting results related to serum / plasma neurotensin levels were reporte...

Introduction: Differentiation between constitutional delay of growth and puberty (CDGP) and congenital hypogonadotropic hypogonadism (CHH) during early adolescence is challenging, as patients exhibit a similar clinical picture and there are no definite clinical or biochemical markers that distinguish these 2 pathologies. A delay in diagnosis, especially for CHH, may have short and long-term health consequences. The aims of this study were: 1) To evaluate the u...

Background and Objectives: Chronic administration of synthetic glucocorticoids affects 1% of the world population and is responsible for secondary adrenal insufficiency for 40% of the patients. In pediatrics, glucocorticoid-induced adrenal insufficiency (GI-AI) diagnosis is based on the Low Dose Synacthen Test (LD-SST). Screening for glucocorticoid-induced adrenal insufficiency implies medical and economical costs due to the necessity of an intravenous line an...

Background and Aims: Congenital adrenal hyperplasia (CAH) resulting from 11β-hydroxylase deficiency (11OHD) is a rare autosomal recessive (AR) disorder due to mutations in CYP11B1. Consequences are decreased cortisol secretion, elevated plasma levels of ACTH, and accumulation of steroid precursors causing abnormally high androgen synthesis and hypertension. High levels of 11-desoxycortisol provides diagnosis with certainty. However, in a cohort o...

Purpose: ACTH-independent bilateral adrenal hyperplasia is a rare cause of pediatric Cushing's syndrome (CS). Our objective was to describe the features of pediatric ACTH-independent CS and to compare groups defined by etiology.Methods: We conducted a retrospective observational study of patients aged 0–18 years at management in 1992–2022 for ACTH-independent CS in any of three Paris university pediatric...
