Background: Vitamin D deficiency (VDD) is common in the general pediatric population of the world. Some studies reported that low vitamin D levels with an increased risk of diabetes.Objective and hypotheses: VDD can be more common in children with type 1A diabetes (DM1A) than those with type 1B diabetes (DM1B). To evaluate 25OHD levels in children with newly diagnosed DM1A and DM1B patients and investigate any relation with clinical and laboratory data a...

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 ...

Background: P450 oxidoreductase (POR) deficiency is a rare cause of congenital adrenal hyperplasia (CAH) with a wide spectrum of clinical phenotypes including glucocorticoid deficiency, difference/disorder of sex development (DSD), skeletal malformations, and Antley-Bixler syndrome. We describe the clinical and molecular characteristics of a large cohort with POR deficiency with long-term data.Methods: The medical record...

Central hypothyroidism (CeH) is characterized by thyroid hormone deficiency due to impairment of pituitary TSH or hypothalamic TRH biosynthesis. CeH is often seen as a part of multiple pituitary hormone deficiencies, but it can also be seen as isolated. Diagnosis may be challenging. To date, some variants that can cause isolated CeH have been identified; although in a number of patients the cause has not been clarified. Recently, variants of the insulin receptor substrate 4 (<...

Introduction: Graves’ disease (GD) is the most common cause of the hyperthyroidism in children and adolescents. Patients may present with norological, ophtalmological, cardiovascular and psychiatric symptoms. The aim of this study is to present the sociodemographic data (age, gender, etc.), clinical findings, quality of life and psychiatric symptoms of the children diagnosed with Graves’ disease and compare these data with the control group matched...

Introduction: Central precocious puberty (CPP) occurs as a result of early activation of the hypothalamic-pituitary-gonadal axis. CPP. In recent years, especially after the COVID pandemic, presentations with signs of precocious puberty and cases requiring treatment have increased all over the world. Recent studies have showed that CPP patients are more likely to have social and psychiatric problems than their peers of the same age and gender. The aimof our stu...

Objectives: Trichorinophalangeal syndrome (TRPS) is a cause of syndromic short stature; and is characterized by typical dysmorphology, ectodermal dysplasia, and skeletal findings. There are two types of TRPS; TRPS-I caused by monoallelic pathogenic variants in the TRPS1 gene, and TRPS-II caused by whole gene deletion. TRPS-II; also called Langer-Giedion Syndrome (LGS), in which multiple exocytoses can be seen in addition to typical TRPS features due t...

Introduction: Juvenile Paget's Disease(JPD) is an extremely rare disease of bone characterized by progressive painful bone deformities, fractures and increased bone turnover. Findings also include deafness, loss of vision, vascular calcification and aneurysm. Here, we report two siblings presented with recurrent fractures and diagnosed as JPD by very high alkaline phosphatase levels and radiographic findings. A novel homozygous mutation in the TNFRSF11B g...

Basal-bolus insulin therapy is currently, the most common treatment modality in children and adolescents with type 1 diabetes mellitus (T1DM) worldwide. Insulin glargine and detemir are two different molecules, produced with small modifications, of human insulin. In this prospective longitudinal study, we aimed to compare HbA1c, time in range in CGM, basal insulin doses and hypoglyccemia frequencies in children and adolescents with T1DM who underwent switching from insulin det...

17β-Hydroxysteroid dehydrogenase type 3 (17β-HSD3) is expressed mostly in the testes and converts the inactive Δ4-androstenedione (A) to testosterone (T). 17β-HSD3 deficiency is a rare autosomal recessive disorder and the most common testosterone biosynthesis defect leading to 46,XY Disorders of Sex Development (DSD). To date, more than 40 mutations of HSD17B3 have been reported. 46,XY patients with 17β-HSD3 deficiency would present with wide variable ...
