Introduction: A positive correlation between the onset of T1DM and winter has been suggested by studies conducted in different countries.Objective: To investigate the seasonal variation of T1DM diagnosis and additional epidemiological parameters in children from Western Greece diagnosed with T1DM.Methods: 105 patients, 44 males and 61 females, aged 1 to 16 years (mean: 8.2±4 y...

Background: In adults, insulin resistance is associated with vascular damage and progressive loss of the endothelial protective functions. Additionally, it further complicates the micro- and macro- vascular environment through increasing oxidative stress and inflammation.Aim: The purpose of this study was to evaluate how apoptosis and antioxidant markers are correlated with biochemical markers in children, during the glucose tolerance te...

The main role of the acid-labile subunit (ALS) is to stabilize the IGFBP3/IGF complexes. Pathogenic variants in the gene coding for ALS (IGFALS) results in IGF1 and IGFBP3 deficiency, short stature, delay puberty and insulin resistance. The aim of these study was to identify the genetic cause in a patient with suspected ALS deficiency. The proband is the third son of non-consanguineous parents, evaluated for the first time at 17.3 years due to short stature (−2....

Steroidogenic factor-1 (SF1), encoded by plays a central role in sex development, steroidogenesis, and reproduction in both males and females. NR5A1 mutations have been described in a diverse spectrum of disorders of sex development (DSD). We report on a case of XY Partial Gonadal Dysgenesis with paternal inheritance of a NR5A1 variant. A 17-year-old girl was referred to us due to primary amenorrhea and absence of secondary female sex characteristics. She was...

Background: Precocious puberty is defined as the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. This condition results from a constant and complex interplay between predisposing genes and environmental factors. To date, the molecular analysis are all focused on reproductive-endocrine disorders such as Kallmann syndrome and hypogonadotropic hypogonadism, while the genetic bases of pubertal timing are still unclear.<p ...

Background: Various endocrine complications are common after HSCT but primary adrenal insufficiency (Addison’s disease, AD) is absolutely rare. To the best of our knowledge, there is only one case of AD reported in a 9-year-old girl after HSCT and busulfan and cyclophosaphamide-based conditioning for myelodysplastic syndrome.Objective: We report on a 14-year-old boy from Albania who developed an Addisonian crisis 12.7 years after HSCT.<p class="...

Background: Despite extensive evidence in adults that lifestyle modification, including a healthy diet, may prevent the onset of type 2 diabetes, studies examining the impact of chronic dietary exposures on insulin dynamics in at-risk children are lacking.Objective and hypotheses: To assess how dietary intake predicts insulin sensitivity and secretion over a 2-year period in children with a family history of obesity.Method: Data st...

Background: Atherosclerosis begins in childhood and progresses silently. Triglycerides/HDL ratio(TG/HDL) is a risk factor for cardiovascular diseases.Objective and hypotheses: To investigate TG/HDL as possible predictive factor for metabolic disorders in children.Method: Descriptive correlation, with 110 children (6–12 years old) in Sparta, Greece. Anthropometric and biochemical analyzes were performed.R...

Background: Congenital hyperinsulinism (CHI; MIM #256450) is the most common cause of persistent hypoglycaemia in children. Recessive inactivating mutations in KATP channel subunits, encoded by ABCC8 and KCNJ11 genes, are the most common cause of CHI. Mutations of these genes usually cause forms of CHI which in the vast majority of patients are unresponsive to first line medical treatment with diazoxide. Multiple daily standard octreotide injections combine...

Background: Current guidelines recommend the priming with low-dose testosterone in prepubertal boys prior to growth hormone stimulation tests. To our knowledge, only few adverse events after low-dose testosterone have been described so far.Objective and hypotheses: To assess possible side effects of testosterone priming.Patients: We studied 188 prepubertal boys aged between 10 and 15 years (mean ± S.D.: 11.4&#17...
