Background: Final height (FH) in patients (pts) with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is often under the genetic target, despite improvement of new therapeutic strategies.Objective and hypotheses: The aim of this study is to evaluate FH in a cohort of pts with CAH due to 21OHD diagnosed before and after newborn screening (NBS) era in Emilia-Romagna, Italy.Method: We evaluated final heigh...

Delayed puberty (DP) is defined as a retardation of sexual maturation beyond the expected age, which conventionally is between 8 and 13 years in females. Since DP due to hypogonadism requires a specific treatment, it is crucial to promptly define the underlying pathogenesis and identify a tailored program of care. Hormonal therapy is essential to promote the development of secondary sexual characteristics, bone, muscle, and social, sexual, and psychologic skills. Despite the o...

Background: X-linked hypophosphatemic rickets (XLH) represents the most common form of hypophosphatemia and leads to vitamin D resistant rickets in children. Even though cranial vault and craniovertebral anomalies of potential neurosurgical interest, namely early closure of the cranial sutures and Chiari type I malformation- have been observed in XLH patients their actual incidence is not established.Aim: Describe and analyze the incidence of cranial and...

Background: Precocious puberty (PP) in girls is most frequently an idiopathic gonadotropin-releasing hormone (GnRH)-dependent PP, being thelarche the typical first sign. It is well established that increased dehydroepiandrosterone sulphate (DHEAS) levels are associated with premature adrenarche and may characterize PP too. However, its relationship with signs of hypothalamic-pituitary-gonadal (HPG) axis activation and estrogen exposure is still to be elucidate...

Cribiform Papillary Thyroid Carcinoma has low prevalence. Our objective is to present a case and to emphasize future implications. We present a female 14.9 years old patient with PWS (del 15 q11-13 by methylation test) with a history of asthma, hepatic steatosis, increased Waist-to-Height ratio, HbA1c 5.86 % and C-Peptide 3.64 ng/mL. She had primary hypotiroidism since 7 years old treated with 25 mg/ day of levothyroxine and impaired fasting glucose since 10 years old with a B...

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: Monogenic diabetes (MD) remains undiagnosed in more than 90% of the cases. However, precise, quick and cost-effective diagnosis is important to choose an adequate treatment and to avoid long-term complications.Objective and hypotheses: To develop and validate a diagnostic tool to improve diagnosis rate of MD in Switzerland, as well as to open new research directions.Method: Targeted next-generation sequencing (NGS) of 3...

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...

Background: Neonatal diabetes mellitus is defined by severe hyperglycemia appearing before 6 months of age. It occurs in about one in 200 000 live births and most cases are known to be of monogenic origin. Classical autoimmune type 1 diabetes mellitus (DM) is exceptional in this age group.Objective and hypotheses: Recently non-HLA type 1 DM susceptibility genes, such as IL18RAP, influencing the rate of progression to diabetes among children with...

Background: 25-Hydroxyvitamin D (25(OH)D) deficiency is reported to be common in patients with rheumatoid arthritis and associated with disease activity, physical disability, and cardiometabolic intermediates; data in patients with juvenile idiopathic arthritis (JIA) are inconsistent.Objective and hypotheses: To assess serum 25(OH)D in children, adolescents, and young adults with JIA, and to identify the risk factors for vitamin D deficiency in JIA patie...
