Background: Short stature homeobox-containing gene (SHOX) is located within the pseudoautosomal region 1 (PAR1) of the sex chromosomes. SHOX mutations and PAR1 deletions encompassing SHOX or its upstream/downstream enhancers have been identified in ~60% of Léri-Weill dyschondrosteosis (LWD) and ~5–15% of idiopathic short stature (ISS) patients. Recently SHOX duplications have been described in LWD/ISS individuals.Case presentation: The boy was ...

Background: The prevalence of macrovascular complications is probably underestimated in children with type 1 diabetes (T1D). Arterial stiffness (AS) represents a subclinical marker of CV risk. The most validated non-invasive method for AS measurement is pulse wave velocity (PWV). There are limited numbers of studies with PWV on children with T1D.Aim: Our aim was to assess the relationship between AS and parameters associated with metabolic control in chi...

Introduction: XLH is caused by mutations in PHEX leading to increased FGF23 levels, phosphate wasting, and impaired endogenous calcitriol synthesis. Affected patients present with rickets and diminished growth velocity during childhood, and osteomalacia and short stature in adulthood. Adult height is linked with health within and across generations suggesting that adult height may be a potential tool for monitoring health conditions, e.g., XLH.<p ...

Background: There is increasing evidence from epidemiological studies that some man-made chemicals present in the environment can disrupt endocrine homeostasis in exposed humans. Exposure during foetal life to e.g. phthalates has been linked to adverse effects on testicular and ovarian development, thyroid homeostasis and growth in postnatal life. Exposure to phthalates fluctuates not only from day to day but also over time which poses a major challenge for ex...

Background: Ovotesticular Disorder of Sex Development (OTDSD – true hermaphroditism) is rare, characterized by the presence of both presence of both testis and ovay tissue. Usually, these patients seek medical attention due to ambiguous genitalia.Case presentation: A 15-year-old boy, with ‘atypical’ genitalia and breast enlargement came for surgical correction. His genitalia had a more masculine aspect at birth and he had been submitted to...

Background: The surgical reconstruction of hypospadias is usually performed during the first 2 years of life but little objective data is available to determine its optimal timing. Whereas the no-early surgery option in DSD management is rising, the results of late genital surgery should be evaluated before advocating this attitude.Objective and hypotheses: To evaluate the outcome of hypospadias surgery according to age and to determine if some complicat...

Background: Combinations of follicle-stimulating hormone (FSH) and human chorionic gonadotropin (hCG) have been successful in treating males with hypogonadotropic hypogonadism (HH). The aim of this study was to investigate the efficacy and safety of corifollitropin alfa (CFA), a long-acting FSH analog, combined with hCG to induce testicular growth and pubertal development in adolescent males with HH.Methods: This was a 6...

Context: In the diagnosis of permanent GH deficiency (GHD) during the transition phase, the 2019 AACE guidelines recommended peak GH-cutoffs of ≤3µg/L and ≤1µg/L for the glucagon test (GST), while a recent investigation identified a value <5.8μg/L as a suitable gold standard (Fava et al, Journal of Clinical Endocrinology and Metabolism, 2024). However, the clinical applicability of this cutoff remains to be confirmed and the potential c...

Background: The calcium-sensing receptor (CaSR) regulates calcium metabolism by modulating PTH secretion, as well as by direct effect on osteoblasts and osteoclasts, balancing bone formation and resorption. Loss-of-function heterozygous mutations on CASR gene can lead to Familial Hypocalciuric Hypercalcemia (FHH; OMIM #145980), a benign autosomal dominant condition of undefined incidence. Dysplasia Epiphysealis Hemimelica (DEH; OMIM #127800) is a rare...

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 ...
