Background: The i.v. GnRH test remains the gold standard for the diagnosis of central precocious puberty (CPP). Unfortunately however, GnRH is expensive and is not available worldwide. GnRH analogues have been used as an alternative, but their place is not established, while very few studies have compared between the two tests.Objective: To compare the effects of GnRH and Triptorelin on gonadotrophin secretion in patients with sexual precocity and hence ...

Background: Neuroendocrine tumors (NETs) represent a complex entity of neoplasm arising from different cell types of neural crest origin. They can produce and/or secrete various hormones or vasoactive substances. Usually sporadic, they can occur in association with other cancers, as part of a multiple endocrine neoplasia type 1 (MEN1), von Hippel–Lindau disease, von Recklinghausen, tuberous sclerosis.Case report: We report a case of neuroendocrine t...

Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

Background: Short stature is the most common presenting symptom in Turner Syndrome (TS). GH treatment helps alleviating short stature in TS, although response to treatment varies significantly.Objective and hypotheses: We aimed to evaluate the response to GH treatment and factors affecting this response in children with TS.Method: Forty-nine patients with TS diagnosed by cytogenetic analysis and who had been followed minimum of 1-y...

Introduction: Congenital hyperinsulinism (CHI) is a rare but severe condition causing persistent hypoglycaemia. Approximately 30-40% of patients require surgical treatment. Extent of surgery depends on the histological form of the disease: subtotal pancreatectomy is done in diffuse CHI, whereas pancreatic resection is recommended in focal CHI.18F-DOPA PET scan is a gold-standard imaging technique that helps in differential diagnosis of diffuse and f...

Background and Methods: PCOS is common and associated with significant comorbidity. However, its pathogenesis is complex and poorly understood. We have developed new methods for deep phenotyping discovery proteomic profiling of urine, aiming to identify disease mechanisms, drug targets and novel non-invasive biomarkers for PCOS in adolescents. Here, we present the baseline proteomic data from our prospective, longitudinal study (n=40). We undertook proteomic analysis ...

Background: The syndrome consisting of primary hypothyroidism, precocious puberty, and massive ovarian cysts was termed Van Wyk and Grumbach syndrome (VWGS) in 1960. Chronic lymphocytic thyroiditis is the more common cause of hypothyroidism in children. In patients with severe longstanding hypothyroidism, the sella turcica may be enlarged due to thyrotrope hyperplasia. Puberty tends to be delayed in hypothyroid children in proportion to the retardation in the bone age, althoug...

Introduction: The diagnosis of GHD requires the coexistence of anamnestic, auxological and laboratory data. The latter are burdened by the poor accuracy and adverse effects of the stimulation tests. A recent european audit (Horm Res Paediatr 2019;92(3): 150-156) on GH diagnostic reported as preferred tests in Italy Insulin tolerance test (ITT), glucagon, clonidine, arginine and Arg-GHRH. We conducted a survey to explore which of them are most used in It...

Introduction: The co-occurrence of Turner Syndrome (TS) and Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKHS) has been rarely described in literature. The resulting clinical picture includes congenital aplasia of the uterus and of the upper two-thirds of the vagina and ovarian dysgenesis.Case Report: We hereby report the case of a 14-year-old girl referred to our endocrine outpatient clinic for pubertal delay. Her previous medical history ...

Background: Animal studies have reported that exposure to synthetic glucocorticoids (sGCs) may lead to inter- and transgenerational effects on offspring phenotype. However, many of these studies are poorly designed, do not account for possible non-epigenetic confounds, and cannot determine the mechanism(s) by which gamete epimutations are induced.Objectives: Firstly, to determine whether developmental exposure of mice to...
