Introduction: Short stature is a common manifestation of Noonan syndrome (NS). GH deficiency, GH insensitivity, and neurosecretory dysfunction have been reported in the literature. The optimal GH treatment for NS is still controversial. In this study, we aimed to evaluate the growth characteristics in addition to clinical features of NS, and the growth response to GH treatment by using a nationwide registration system.Material and methods: Children and a...

Background: Primary adrenal insufficiency other than congenital adrenal hyperplasia (non-CAH PAI) is very uncommon in children but associated with a variety of molecular defects. Biosynthesis of adrenocortical hormones is reduced although the relation of steroid profiles with underlying molecular etiology is not yet studied.Objective: Investigation of clinical and steroid hormone profiles of a multicenter cohort of child...

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...

Background: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires accurate diagnosis and urgent treatment. Congenital adrenal hyperplasia is the most common cause of PAI in children. Non-CAH causes of PAI are relatively rare. Although several molecular causes have been found, it is emerging that considerable overlap in the clinical and biochemical features of these conditions exists.Objective and hypotheses: We inv...

Congenital rubella infection is a transplacental infection that can cause intrauterine growth retardation, cataract, patent ductus arteriosus, hearing loss, microcephaly, thrombocytopenia and severe fetal injury. It has been shown that type 1 diabetes mellitus develops in 12–20% of patients with congenital rubella infection and disorder in oral glucose tolerance test is observed in 40%. A 13-year-old male patient presented with complaints of new-onset polydipsia, urinatio...

Objective: Most recent evidence from conducted in human and animal studies suggests that vitamin D has a potential role in the physiology of reproductive function in both genders. We investigate the role of vitamin D in male and female gonadal function at mini-puberty period with particular emphasis on production of sex steroids and gonadal peptide hormones. Additionaly, this study evaluated serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradio...

The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause vitamin D-dependent rickets type 1A (VDDR-IA, OMIM 264700), which is a rare autosomal recessive disorder. Herein we report five patients with 1α-hydroxylase deficiencies. We studied six patients from three families who diagnosed as 1α-hydroxylase deficiency clinically. All patients had hypocalcemia, hypophosphatemia, hyperphosphatasemia, elevated serum PTH, normal or high v...

Childhood obesity (CO) is an important risk factor for the development of many chronic metabolic diseases in adulthood. Sleep patterns are known to affect leptin and ghrelin levels in the body. Recent studies using Functional Magnetic Resonance Imaging (fMRI) have shown that insufficient sleep time leads to unhealthy eating behaviors in the brain. The aim of this study is to investigate the association between sleep time in childhood and obesity. Consistent with this associati...

Studies show that vitamin D deficiency can have negative effects on glucose homeostasis, although the mechanism for this is still unclear. The possible mechanism may be related to the presence of vitamin D receptors and their metabolizing enzymes in insulin-sensitive cell types, such as pancreatic cells and adipocytes. The aim of this study is to compare how serum 25- OH D level and HOMA-IR index are related to acanthosis nigricans (AN) and which of them is a better marker for...

In children and adolescents, vitamin D deficiency negatively affects muscle physiology, exposing them to increased muscle damage and pain, stress fractures, and tendon structures. In addition, free radicals released when the body is exposed to oxidative stress after exercise can cause DNA damage. Vitamin D plays an important role in removing these radicals. The purpose of this study is to investigate the relationship between physical activity and 25- OH vitamin D in obese chil...
