Short-chain L-3-hydroxyacyl-CoA (SCHAD, HADH) deficiency is characterized by diazoxide-responsive hyperinsulinemic hypoglycemia in the neonatal or infancy periods. These patients have severe protein (especially leucine) sensitivity. HADH mutations are recessively inherited with less than 50 patients reported so far. The mechanism behind unregulated insulin secretion in SCHAD deficiency is not understood but may involve changes in protein-protein interactions with glutamate deh...

Background: Cushing's syndrome (CS) is very rare in children and the most common cause is the high doses of glucocorticoids (GC) administered. It is well known that application of potent GCs cause iatrogenic CS (ICS) due to suppressing hypothalamo-hypophyseal-adrenal (HPA) axis and later even adrenal insufficiency (AI). Other side effects of GCs are also seen in these patients.Objective: The aim of this study is to r...

Background: Genetic diversity of mutations in the CYP21A2 gene is the main cause of the monogenic Congenital adrenal hyperplasia (CAH) disorder. On chromosome 6p23.1, the CYP21A2 gene is partially overlapped by the TNXB gene and reside in tandem with their highly homologous corresponding pseudogenes (CYP21A1P and TNXA), which leads to recurrent homologous recombination.Methods and Results: The genetic s...

Introduction: Craniopharyngiomas can lead to pituitary insufficiency and long-term endocrine complications due to the location, invasive character and risk of recurrence, besides they known as histologically benign.Aim: In this study, we aimed to evaluate the demographic, clinical features, endocrinological problems and follow-up findings in patient with craniopharyngioma in childhood.Metho...

Introduction: DAX1 (NROB1) mutation, that is among the causes of primary adrenal insufficiency; is revealed with X-linked congenital adrenal hypoplasia and hypogonodotropic hypogonadism. Growth hormone (GH) deficiency is not common in affected individuals. In the literature, there are few cases of GH treatment . growth hormone therapy in two cases with DAX1 gene mutation were evaluated in clinical features and treatment responses.<strong...

Background: Both CYP24A1 and SLC34A1 gene mutations are responsible for idiopathic infantile hypercalcemia (IIH). Whereas loss-of-function mutations in CYP24A1 (25-OH-vitamin D-24-hydroxylase) lead to a defect in the inactivation of active 1,25(OH)2-vitamin D3, mutations in SLC34A1 encoding renal sodium-phosphate co-transporter NaPi-IIa lead to primary renal phosphate wasting combined with an inappropri...

Objective: We aimed to investigate the usefulness of abdominal adiposity and total body fat as predictors of cardiometabolic health, especially insulin sensitivity, in children and adolescents.Methods: Participants were 479 children and adolescents with obesity (322 boys and 157 girls) aged 3 to 18 years attending the Children's Hospital at Zhejiang University School of Medicine (Hangzhou, China). Participants underw...

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...

Introduction: CAH is a common clinical condition with treatment and follow-up challenges. As a result, the adult height of the cases is known to be affected. We aimed to assess the growth and pubertal development of CAH patients and the factors that influence final height.Method: Between 1980-2022, 41 patients diagnosed with CAH were observed at our clinic. Only cases that attained the final height were retrospectively a...

Background: There is a small proportion of children born SGA without postnatal catch-up growth who are presented with persistent short stature, low BMI, and decreased lean body mass (LBM). Data on body composition are rarely reported in the literature. Our study addresses the question whether human recombinant GH treatment could affect body composition in these SGA children or not.Design: We included 58 SGA children (n=20 females) with SGA (birt...
