Introduction: in females with precocious thelarche (PT) (< 8 years), elevation of morning luteinizing hormone levels (mLH) may be indicative of pubertal activation of the pituitary gonadal axis. However, this approach could not be satisfactory in real life management of PT due to the risk of reduced specificity and sensitivity of the mLH thresholds. We propose a diagnostic flow-chart based on basal and stimulated gonadotrophins integrated with bone age and ...

Introduction: The gonadotropin releasing hormone stimulation test (GnRHST) is commonly used to screen CPP. Some recent studies reported that morning unstimulated luteinizing hormone levels may be sufficient to discriminate pubertal from prepubertal children. The aim of this study is to evaluate the clinical efficacy of mLH to screen CPP in femalesPatients and Methods: We retrospectively studied the clinical and hormonal ...

Background: Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) or autoimmune polyendocrinopathy type 1 (APS-1) is a rare monogenic autosomal recessive disease due to pathogenic variants in the AIRE gene. APECED usually begins during early childhood with chronic mucocutaneous candidiasis (CMC), followed by hypopathyroidism (HP) and Addison’s disease (AD); however, other endocrine and non-endocrine components may occur with a different prevalen...

Background: Differences of sex development (DSDs) (conditions with atypical development of chromosomal, gonadal or anatomic sex) are classified into three groups: sex chromosome DSD, 46,XYDSD and 46,XX DSD. Around 1 newborn in 5000 presents ambiguous genitalia with a major challenge for male or female assignment. The identification of a genetic cause can contribute to a correct diagnosis and to optimize both management and genetic counselling.<p class="abs...

Introduction: Central Precocious Puberty (CPP) has recently been described in patients with isolated or syndromic neurodevelopmental disorders, with greater attention from the scientific community. We carried out this study to compare the main aspects of non-isolated and isolated forms of CPP.Methods: We conducted a retrospective monocentric study, collecting all treated cases of CPP from 1st January 2013 to 31 December ...

Non-autoimmune hypothyroidism is characterized by high serum TSH level, normal or low thyroid hormones, absence of autoantibodies and normal or hypoplasic in situ thyroid gland. It is known that heterozygous mutations in the TSH receptor gene (TSHR) are associated with partial TSH resistance which clinically ranges from isolated hyperthyrotropinemia to non-autoimmune hypothyroidism. Despite this, an absence of mutations in the TSHR gene has been repo...

Introduction: Growth failure is a side effect of HSCT in children. This study aims to evaluate the growth trajectory in a series of boys who underwent allogeneic HSCT for childhood cancer in pre-puberty and reached final height (FH).Methods: We evaluated auxological parameters, mid-parental target height (TH), serum testosterone, and insulin-like growth factor 1 (IGF-1 SDS) levels of 19 boys who underwent allogeneic HSCT...

The measurement of serum FGF23 plays a pivotal role in the differential diagnosis of patients with hypophosphatemia. However, its interpretation may be difficult in some cases. We report the case of a child with rickets and severe hypophosphatemia, where both intact FGF23 (iFGF23), the active form, and C terminal FGF23 fragments (C-FGF23) were measured.Case report: A 5.7-year-old girl, born at term from first-grade-related Pakistani pare...

Background: In young adults patients (pts) with CAH due to 21OHD few and conflicting data have been reported on bone mineral quality (BMQ) evaluated by quantitative ultrasound (QUS).Objective and hypotheses: To evaluate the bone mineral status by QUS variables assessed at proximal phalanges of the hand in a cohort of young adults with classical CAH due to 21OHD and the possible associations with their clinical and metabolic features.<p class="abstext...

Background: Thyroid nodules (TN) are rare in children but often show more aggressive features than in adults. Irradiated childhood cancer survivors (CCS) are at risk for malignant thyroid nodules.Objective and hypotheses: To retrospectively compare the incidence of differentiated thyroid cancer (DTC), the clinical onset and the medium-term follow-up in a pediatric population (EC <18 years), with and without risk factors examined for TN, among 1990 an...
