Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

Background: Dyslipidaemia is related with the initiation and progression of atherosclerosis in children, and the total cholesterol (TC) and non-high density lipoprotein cholesterol (non-HDL-C) are commonly used screening tools for identifying children with dyslipidaemia. The triglyceride-to-high density lipoprotein cholesterol (TG/HDL-C) ratio has recently been reported as a marker of insulin resistance in obese children and adolescents.Objective and hyp...

Background: The short stature homeobox-containing (SHOX) gene, located in the telomeric pseudoautosomal region 1 (PAR1) on the short arm of both sex chromosomes, is important for linear growth.Objective and hypotheses: The aim of our study was to evaluate the presence of SHOX gene deletions/point mutations in children with short stature in order to understand the role of SHOX gene in idiopathic short stature (ISS) and estimate its frequency.<p class=...

Background: Inter-individual differences in the metabolism of cortisol have been postulated to emerge during puberty, and might be explained by a complex interplay of genetic and environmental factors. The aim of the current study was to estimate the relative contributions of genetic, shared environmental, and unshared environmental factors on cortisol metabolism in a longitudinal twin cohort assessed at pre-pubertal, mid-pubertal and post-pubertal ages....

Background: Polymorphisms in several genes may be associated with a higher risk of obesity and non-alcoholic fatty liver disease (NAFLD).Objective: To examine the association of single nucleotide polymorphisms (SNPs) −238G>A, −1031 T>C and −863 C>A of Tumor Necrosis Factor-α (TNFA) gene; rs738409 C>G of patatin-like phospholipase domain containing 3 (PNPLA3) gene; +276 G>T and +45 T>G of Ad...

Background: Cholesterol levels are variable throughout childhood and adolescence. The attention not only to conventional lipid profiles but also to non-high-density lipoprotein cholesterol (non-HDL-C) and triglyceride to HDL-C ratio (TG/HDL-C ratio) are becoming more apparent in pediatric lipid studies because of their clinical importance.Objective and hypotheses: The aim of the present study was to establish age- and gender-specific reference values for...

Introduction: Type 5 monogenic diabetes is an autosomal dominant disease due to a mutation in HNF1beta gene. This gene is expressed predominantly in kidney and pancreas, thus clinical manifestations are characterised by renal abnormalities and diabetes.Objectives: To review the clinical characteristics of patients who were diagnosed with type 5 monogenic diabetes in the Pediatric Endocrinology Unit of a tertiary referral hospital.<p class="a...

Hyperinsulinism is a common cause of severe and persistent hypoglycaemia during the neonatal period. Eleven genes have been identified that lead to unregulated insulin secretion and hyperinsulinemic hypoglycaemia (HH). Inactivating mutations in UCP2 gene have been described in a very small number of patients with HH. UCP2 protein is an inner mitochondrial carrier protein and its loss of function causes enhanced glucose oxidation and increased intracellular ATP synthes...

Introduction: Idiopathic intracranial hypertension (IIH) is a rare entity in childhood. It is characterized by signs and symptoms of increased intracranial pressure with normal neurological examination (except for possible paresis of the sixth cranial nerve), cerebrospinal fluid study and neuroimaging. The association between HII and treatment with growth hormone (GH) was first described in 1993 by the Food and Drug Administration and it has later been demonstrated. Incidence ...

Background: Hypocalcemia is a common metabolic disorder in the neonatal period and may involve life-threatening situations. The aim is to analyze the main causes of hypocalcemia and its management.Objective and hypotheses: The aim is to analyze the main causes of hypocalcemia and its management.Method: Retrospective descriptive study by reviewing reports of 75 patients diagnosed of neonatal hypocalcemia (total Ca <7.6 mg/dl and...
