Background: Both genetic and environmental factors serve as the trigger of Hashimoto's thyroiditis (HT), but the exact mechanisms are still not fully understood. Increased intestinal permeability was shown to be a constant and early feature of several autoimmune disorders. Although HT is the most common autoimmune disorder worldwide, the role of intestinal permeability in its pathogenesis had received little attention. Human zonulin modulates intracellular...

Background: GnRH agonists, leuprolide acetate (LA) and triptorelin acetate (TA), have been widely used in the treatment of central precocious puberty (CPP). But, a comparative data on the effectiveness of these two drugs for CPP treatment is very scarce.Objective: To compare the efficacies of TA and LA treatments in girls with idiopathic CPP.Patients and Methods: Sixty girls with rapidly progressive CPP treated with LA (n=...

Background: Intrathyroidal ectopic thymus (IET), a benign lesion due to aberrant thymic migration during embryogenesis, is often discovered incidentally. Most of the reports in the literature describe individual cases or small series. We aimed to present the ultrasound (US) features, diagnostic methods, and follow-up of IET in children and adolescents.Methods: We searched our database of patients under 18 years old with ...

Introduction: Widespread changes occur in gene expression in obesity, contributing to metabolic and inflammatory abnormalities. Epigenetic mechanisms play a role in obesity by altering gene expression patterns, and connecting environmental factors to genetic alterations. Histone acetylation is a crucial epigenetic modification that impacts chromatin structure and regulates gene expression. Adipogenesis has been associated with gene-specific increases in histon...

Introduction and Objective: Puberty marks the transition from childhood to adulthood, initiated by the activation of the hypothalamic-pituitary-gonadal axis. Anti-Müllerian hormone (AMH) and inhibin B, both secreted by granulosa cells, play crucial roles in pubertal development and reflecting ovarian reserve. Establishing reference intervals for AMH and inhibin B across different pubertal stages is essential for assessing ovarian function and identifying ...

Context: Corticotropin-releasing hormone (CRH)-stimulated inferior petrosal sinus sampling (IPSS) has an important role in the differential diagnosis of hypercortisolism of pituitary or ectopic origin as the most accurate procedure in terms of sensitivity and specificity compared with clinical, biochemical and imaging analyses. However, due to the cost and unavailability issues of CRH, desmopressin may be an alternative to CRH during IPSS.<p class="abstext...

Objective: Monosomy 18q and 10p duplications rare chromosomal disorders that are caused by deletion of a part of the long arm (q) of chromosome 18 and duplication of genetic material on the short arm (P) of chromosome 10 respectively. In both disorders the phenotype is highly variable and; includes short stature, developmental delay, hypotonia, and facial dysmorphic features. Also, genital abnormalities could occur in both disorders. Genital abnormalities (cry...

Objective: Vitamin deficient (VDD) rickets can manifest with skeletal (hypocalcemia, hypophosphatemia, elevated serum alkaline phosphatase and defective bone mineralization) and extra-skeletal findings. There are certain number of case reports and limited number of small scale studies reporting dilated cardiomyopathy due to VDD rickets.The aim of the present study is to evaluate the clinical, biochemical and echocardiographic features of...

Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder caused by a defect in any of the enzymatic steps of adrenal steroidogenesis. It occurs due to mutations in genes that encode enzymes involved in the synthesis of cortisol from cholesterol. The most common cause is 21-hydroxylase deficiency, with 11-beta hydroxylase, 3-beta hydroxysteroid dehydrogenase, 17-alpha hydroxylase and POR deficiency being among rarer causes.Objec...

Objective: The systemic form pseudohypoaldosteronism type 1 (PHA1) is an autosomal recessive disorder characterized with defective sodium transport in many organ systems including kidney, lungs, colon, sweat glands and salivary glands. Homozygous or compound heterozygous loss-of-function mutations in the genes encoding amiloride sensitive epithelial sodium channel (ENaC) account for genetic causes of systemic PHA1.Case 1: Male patient presented with vomi...
