Introduction: Variegated mosaic aneuploidy syndrome (MVA) is a rare autosomal recessive disease characterized by a variable percentage of chromosomal gains and losses, resulting in multiple mosaic aneuploidies, which explains a great phenotypic variety and may predispose to the development of cancer. Bi-allelic mutations in CEP57 are the cause of MVA2. CEP57 encodes a centrosome protein involved in microtubule stabilization and is crucial for maintaining prope...

Introduction: Hashimoto’s thyroiditis (HT) is one of the most common autoimmune diseases in childhood. Despite its frequency, there are still controversies concerning the spontaneous evolution and presentation in childhood. Aim and methods: this is a retrospective study aiming to evaluate clinical and hormonal features at diagnosis and auxological parameters after 3 years in subjects with Severe Autoimmune Hypothyroidism (SAH). We defined severe hypothyr...

Background: in general population Hurthle cell cancer (HCC) accounts for 3-7% of all differentiated thyroid cancers (TC) with a more aggressive course, while its relative prevalence and behavior in childhood is uncertain due to the lack of specific literature reviews.Objective: to describe the largest pediatric HCC cohort to date reported and to estimate its relative prevalence among TC variants in childhood.<p c...

Introduction: Autoimmune polyendocrine syndrome type I (APS-1) also called autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare monogenic autosomal recessive disease known by the triad of the major components hypoparathyroidism, primary adrenocortical insufficiency and chronic mucocutaneous candidosis. However, many minor diseases could be present such as other endocrine manifestations (gonadal insufficiency, DM type 1, thyroid dis...

Objective: Type 2 Diabetes Mellitus(T2DM)and obesity represent two major health hazards in children and adolescents, with rising prevalence. Several markers have been developed in order to diagnose T2DM and detect potential metabolic abnormalities.The objective of the study was to examine glucose tolerance in Greek children and adolescents and the differences in the glucose, insulin and c-peptide response curves between male and female children and adolescents...

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 ...
