Background: Primary ovarian insufficiency (POI) is genetically mediated in up to 30% of cases. Many genes associated with POI have roles in early ovary developmental processes, including meiosis.Objectives: We investigated the genetic mechanism underlying early-onset POI in three young women presenting with absent puberty: two sisters from a consanguineous pedigree and a third unrelated proband.<st...

Aim: To determine Sertoli cell function at diagnosis and after 3 months of chemotherapy.Methods: A prospective cohort study was performed including children with acute lymphoblastic leukaemia, acute myeloid leukaemia, or non-Hodgkin lymphoma. Serum levels of AMH were evaluated at diagnosis and after 3 months during chemotherapy. Results were analysed as standard deviation scores according to pubertal stage and expressed ...

GHD diagnosis in neonates and infants is a challenge owing to the fact that GH pharmacological stimulation tests (GHST) are not approved at this age. In a retrospective study, we found that a random GH<6.5 µg/L confirmed GHD diagnosis in neonates with clinical suspicion of GHD with high diagnostic accuracy (1). The accuracy of GH and its surrogates of action have not been set for infants with current standardized immunoassays.Objective</...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Background: Childhood onset PTC has a more aggressive presentation but no overall increase in mortality compared to adults.Objective: To characterize a pediatric cohort with PTC at diagnosis using the American Thyroid Association (ATA) Initial Risk Stratification (IRS) and to evaluate the response to initial treatment until 3 years based on the modified ATA Dynamic Risk Stratification (DRS) for adults.<p class="abste...

Introduction: NR5A1 (nuclear receptor subfamily 5 group A member 1) is a transcriptional regulator of adrenal and gonadal development and function. Heterozygous and homozygous NR5A1 mutations have been described in 46,XY disorders of sex development (DSD). The clinical, endocrine and genetic features of three 46,XY children from two unrelated families (A and B) with NR5A1 genetic variants are reported.P...

The transition phase is the period from the end of puberty until achievement of full adult maturity. We report the results from 45 patients with pituitary deficiency (15-24.9years), 28 (16males) with congenital insufficiency (G1) and 17 (10males) with acquired disease (G2), evaluated at the end of GH therapy. All cases had confirmed GH deficiency; 89.2 % of cases from G1 had multiple pituitary deficiencies (TSH 23/28, LH/FSH 19/28, ACTH 15/28 and Prolactin 3/28), 94.1 &#37...

Introduction: The diagnosis of Congenital Adrenal Hyperplasia (CAH) is a challenge due to the complexity of its pathophysiology and the variety of clinical manifestations. Female newborns (NB) with classical forms present virilization of the external genitalia while in boys it is usually normal. Salt-losers boys and girls are highly susceptible to develop acute adrenal insufficiency and death in the first weeks of life; for these reasons, Neonatal Screening (NS) programs have ...

Background: Disorders of sex development (DSD) are those congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. 45,X/46,XY mosaicism results in a large clinical spectrum of DSD including from female patients with Turner’s syndrome to normal appearing males.Objective and hypotheses: The main aim of this study is to review the clinical and gonad histological findings in a cohort of chromosomal DSD patients f...

Background: Mammary duct ectasia is a bening breast condition which affects primarily middle-aged to elderly women. However, it can occurs wherever there is breast ductal epithelium.Case presentation: A 9-years-old boy was referred to the regional paediatric endocrine clinic from the General Practicioner due to gynaecomastia. Pubic hair development started at the age of 8. Personal and family history were unremarkable except for a history of coping with ...
