Introduction: Familial male-limited precocious puberty (or testotoxicosis) is a very rare genetic disorder with autosomal dominant transmission that causes gonadotropin-independent precocious puberty due to mutations activating the lutropin-chorionic gonadotropin receptor (LHCGR), which lead to elevated testosterone levels and suppressed gonadotropins. The age of onset is between 2-5 years essentially with penis and testes enlargement, linear growth accelerati...

Introduction: Non-nutritional rickets forms are often unrecognized. A late diagnosis could negatively affect the outcome. The aimof this study is to identify peculiar clinical and biochemical signs at the onset of non-nutritional rickets to promote early diagnosis.Materials and Methods: A retrospective monocentric observational study was conducted on a sample of outpatients consecutively evaluated at the pediatric endocr...

Background: Management of subclinical hypothyroidism (SH) in infancy is still controversial. According to the European Guidelines for Congenital Hypothyroidism (CH), in case of TSH levels between 6 and 20 µUI/ml, both levothyroxine (L-T4) therapy and a wait-and-see approach can be considered.Aim: to describe the evolution of SH diagnosed in newborns recalled by neonatal screening (TSH values ≥7µUI/ml)....

Background: In Androgen insensitivity syndrome (AIS) is a hereditary disease in which AR mutations in 46,XY patients present with partial (PAIS) or complete (CAIS) defects in virilisation.Objective and hypotheses: The aim was to analyze the effect of lack of androgen action in germ cell (GC) health and survival along postnatal development, previous to Sertoli cell (SC) pubertal maturation.Method: The histological features and quant...

Background: To diagnose non classical congenital adrenal hyperplasia (NCCAH) and adrenal insufficiency (AI), current guidelines recommend ACTH test. Cutoffs for 17 hydroxyprogesterone (17OHP) and cortisol are derived from immunoassays values. Thanks to a recently developed and validated mass spectrometry approach (LC-MS/MS) we routinely quantify simultaneously 16 circulating steroids and we are able to speculate on new cut off values and uses.<p class="abs...

Achieving adequate glycaemic control in children with type 1 diabetes (T1D) is essential to reduce incidence and progression of microvascular and macrovascular complications. However, factors that influence glycaemic control remain to be understood. The present study aimed to evaluate clinical, personal, genetic and eating behaviour characteristics underlying glycaemic control in T1D. 325 T1D individuals aged 6 and 20 years and with at least 1 year of disease duration have bee...

Achondroplasia is a rare genetic condition caused by a recurrent pathogenetic variant in the FGFR3 gene resulting in short limb skeletal dysplasia. Due to the wide-ranging anomalies associated with achondroplasia (both peculiar clinical features and complications), a multidisciplinary team is often required for ongoing care, although the nature of specialists involved differs among countries. Despite a European consensus on principles for the management of achondropla...

Background: Central precocious puberty (CPP) is defined as the secondary sexual characteristics onset before 8 years of age in females and before 9 in males, due to premature activation of the hypothalamic-pituitary-gonadal axis. The underlying cause remains idiopathic in the great majority; based on the 2009 Consensus, 2% to 7% of girls who have onset of CPP between the ages of 6 and 8 years have unsuspected pathology and only 1% have a tumor such...

Background: Obesity is a persistent disorder that almost universally recurs following treatment, suggesting a disruption on central nervous system control over energy homeostasis. Recent literature suggests that hypothalamic inflammation may have an important role on obesity pathogenesis. This inflammatory reaction, which histologically appears as a reactive gliosis, may be detected using magnetic resonance imaging (MRI), and has just been shown in rodent models and adults.</p...

Background: The initial L-T4 dose currently recommended in the treatment of congenital hypothyroidism (CH) is 10–15 mcg/kg per day.Objective and hypotheses: We designed a multicenter randomized trial to evaluate the effects of different starting doses of L-T4 within the range 10–15 mcg/kg per day on neurocognitive development in children with CH.Method: Seventy-two children with CH diagnosed by neonatal screening were enr...
