Background: Rapid BMI increase in early childhood was found to be a contributing factor for impaired final height in boys with Cystic Fibrosis (CF). This may be explained by early adrenarche triggering an accelerated bone maturation resulting in a compromised growth spurt during puberty, comparable to children with SGA. In healthy Dutch boys, adrenarche starts from the age of 9 years with DHEAS ≥ 1 µmol/L. In Dutch girls, the onset of adrenarche is fr...

Background: Cytochrome P450 side-chain cleavage enzyme (CYP11A1 gene) catalyses the conversion of cholesterol to pregnenolone in steroidogenic cells, the first step in the biosynthesis of all steroid hormones. SCC deficiency has been established as an autosomal recessive disorder caused by inactivating homozygous or compound heterozygous mutations in the CYP11A1 gene, with a wide phenotypic spectrum ranging from prematurity, complete underandrogenization and severe early-onset...

Introduction: Von Hippel-Lindau disease(VHL) is an autosomal dominantly inherited tumor syndrome that predisposes to development benign and malignant tumors. The prevalence of VHL disease is one in 36,000, and the penetrance is higher than 90%. PCC occur in up to 20% of VHL patients. Classically, it is characterized by having an adrenal location, mostly bilateral and being derived from the sympathetic nervous system, resulting in the releases of catecholamines...

Background: Genetic defects in the insulin receptor (INSR) are rare. Precise prevalence is unknown and significant clinical heterogeneity exists. Over 120 allelic variants have been described to date, spread throughout the receptor, and few geographical founder effects have been described. In this case series we identify a novel missense mutation in the tyrosine kinase domain of the INSR in three independently ascertained Irish families.Objective and Hyp...

Background: Thyrotropin receptor (TSH-R) stimulating autoantibodies (TSAb) are present in 90-100% of patients with Graves’ disease (GD). TSAb are functional, impact thyroid function, and are clinically relevant. This study we performed in a pediatric patients with dynamic of Graves’ disease before and during methimazole therapy and in patient with Hashimoto’s thyroiditis using a novel and ultra-rapid TSAb andTBAb bioassay.<p class="abstex...

Introduction: The most common cause of elevated TSH is iodine deficiency, and other common causes are drug use, systemic diseases, and underlying genetic conditions.Objective: We aimed to investigate molecular genetic etiology, genotype-phenotype relationships and the follow-up data in cases with elevated TSH initiated on L-thyroxine treatmentMethods: We retrospectively evaluated c...

Objective: Elevated serum alkaline phosphatase (ALP) levels in pediatric patients can result from various etiologies, with transient hyperphosphatasemia, bone pathologies, and hepatic diseases being the most common. This study aimed to elucidate the etiological factors responsible for elevated ALP levels and to evaluate the clinical presentations of transient hyperphosphatasemia in these patients.Materials and Methods: T...

Background: Maternal overweight/obesity during pregnancy and excessive gestational weight gain (GWtG) have been recognized as important early-life risk factors for childhood obesity. We aimed to examine whether maternal BMI at 20 weeks of gestation and excessive GWtG were associated with alterations in body composition and metabolism in childhood in the offspring of primiparous mothers who participated in a randomised controlled trial of exercise regimen during pregnancy.<...

Introduction: Delayed or absent puberty is thought to be common in boys with Duchenne Muscular Dystrophy (DMD).Objective: To evaluate testicular development, function and puberty in DMD in a 12 months prospective longitudinal study.Methods: Thirty-four boys had assessment of puberty and testes volume by a single endocrinologist. Testes volumes were converted to Z-scores adjusted for bone age. Boys were divided into group A [Baselin...

Objective Recent studies suggest that boys are undergoing puberty at a younger age. Further, the number of idiopathic male central precocious puberty (CPP) cases are increasing over time. Only a few studies have evaluated the etiological factors in boys with CPP. We describe the etiology of CPP. Further, we define key auxological and clinical cues indicative of organic CPP (OCPP) and characterize the incidence of CPP.Methods&#x20...
