Background: Cardiovascular complications are the leading cause of mortality and morbidity in patients with type 1 diabetes (T1D), and early assessment is crucial. Our study aimed to determine the impact of diabetes on vascular health by monitoring 24-hour ambulatory blood pressure (ABPM) and measuring arterial stiffness (AS) in children with T1D.Methods: Seventy-four consecutive children with T1D and 68 age and sex-match...

Autosomal dominant pseudohypoparathyroidism type-Ib is characterized by renal parathyroid hormone resistance, with resultant hypocalcemia and hyperphosphatemia. This disorder is associated with an isolated loss of methylation at GNAS exon A/B and most patients carry maternal microdeletions in the neighboring STX16 gene. The shortest deletion overlap is a 1.2-kb region spanning STX16 exon 4 and thought to harbor a cis-acting element regulating GNAS A/B methylation. However, abl...

Objectives: We aimed to evaluate the performance of waist circumference triglyceride index(WTI) to predict non-alcoholic fatty liver disease(NAFLD) in obese children.Methods: In this study 139 obese children(71 girls) were included(6-18 years). Height, weight, body mass index(BMI), waist circumference(WC), puberty stage, blood pressure, and biochemical values were obtained from the medical records. SDS and percentiles we...

Background: ATP-binding cassette transporter A1 (ABCA1) mediates the transport of cholesterol and phospholipids from cells to lipid-poor apolipoproteins. It has been demonstrated that the ABCA1 gene C69T single nucleotide polymorphism (SNP; TT genotype) is associated with lower HDL cholesterol and higher triglycerides (TG) levels. The relation of this polymorphism with type 2 diabetes mellitus has also been shown.Objective and hypotheses: As dys...

Background: Paternally expressed mono-allelic pathogenic variants in the MAGEL2 (melanoma antigen L2) gene cause Schaaf-Yang syndrome (SHFYNG), a multisystem disorder with psychomotor delay, intellectual disability, behavioral abnormalities, and obesity. Severity of the disease is highly variable, some patients may die in utero and some can live with moderate disabilities. MAGEL2 gene is located in the 15q11.2– q13 region which includes...

Achieving optimal metabolic control can be extremely challenging in some children and adolescents with T1DM. The adherence to multiple injections/day is among the leading causes of suboptimal control. Recently insulin degludec/aspart co-formulation (70%IDeg+30%IAsp: IDegAsp) has become available. Because of the longer-duration of IDeg, and retained individual pharmacokinetics of IDeg and IAsp, we wanted to test insulin IDegAsp's efficacy in our patients with po...

Objective: Congenital isolated ACTH deficiency (IAD) is a rare autosomal recessive disorder that is characterised by low levels of plasma ACTH and cortisol with normal pituitary structure and hormones. Clinical presentation can occur in the neonatal period, as well as later in childhood. Here, we report a patient with IAD due to a novel TPIT mutation.Case: A 48/12 years old girl presented with loss of concioussness and found to be hypoglycemic...

Objective: Antley-Bixler syndrome Type 1 (ABS1) is a rare form of craniosynostosis characterized by multiple dysmorphic features, radio-humeral synostosis and urogenital abnormalities due to P450 oxidoreductase (POR) gene mutations. ABS is also associated with adrenal and gonadal failure which are sometimes underrecognized due to predominance of skeletal findings in various clinics. We report a female patient with very characteristic skeletal and facial features of AB...

Background: Precocious puberty has a complex and polygenic etiology. To describe genetic factors affecting onset and regulation of puberty and pathophysiology of precocious puberty, further studies are needed. Although, it is reported that ACTH receptor MC4R has impact on premature adrenarche, MC2R is expressed in the adrenal cortex and has a major role on the control of hypothalamo-pituitary-adrenal cortex. Melanocortin signaling system is reported to have l...

Background: Borderline precocious and normal-onset puberty can show slow or fast course. The fast development of pubertal signs can be resulted in decrease in final height (FH) via accelerated growth and bone maturation.Objective and hypotheses: To study the effectiveness of GnRHa in improving FH in girls with advanced bone age (BA) and decreased predicted height (PH) in borderline early or normal physiological puberty.Method: 135 ...
