Background: overexpression of the oncogene Yes-associated protein 1 (YAP1), a Hippo pathway target, associates with increased cell proliferation in some human cancers. There is not data on adrenocortical tumors (ACT). YAP1 is a potential target of Wnt/β-catenin pathway, which plays an important role in ACTs.Objective and hypotheses: to evaluate the role of YAP1 and its interaction with the Wnt/β-catenin pathway in ACT.Met...

Background: H syndrome (OMIM #602783) is an autosomal recessive syndrome resulted from mutations in the SLC29A3 gene, encoding hENT3 protein. Characteristic findings are cutaneous hyperpigmentation, hypertrichosis, hepatosplenomegaly, hypogonadism, hyperglycemia/diabetes mellitus, cardiac anomalies, hallux valgus and short stature. Herein we report a girl with multiple endocrinopathies due to H syndrome.Case: Ten year and 5 month old girl was referred be...

Background: IGF1 is a biomarker of GH, and is often used to titrate the dose of GH therapy. However, IGF1 production is regulated by not only GH but also other factors.Objective and hypotheses: We investigated whether the increase in IGF1 at several time points after the commencement of GH therapy could be a predictive factor for the improved growth.Method: We studied 45 pre-pubertal patients with GH deficiency (GHD) that had conti...

Background: Few studies have described the phenotypic spectrum of Septo-Optic Dysplasia (SOD). The aim of this study was to evaluate the range of H-P structural abnormalities and the endocrine morbidity of children with SOD and related disorders.Methods: Retrospective longitudinal single centre study of children with SOD (n:171), Multiple Pituitary Hormone Deficiency (MPHD) (n:53) and Optic Nerve Hypoplasia (ONH) (n:35).<p class="ab...

Background: The diagnostic use of IGF-1 in children suspected of GHD is based on the assumption that a single determination of this parameter reflects the integrated 24-h GH secretion. IGF-1 levels are low in GHD, but a study found a significantly lower sensitivity in children with organic lesions in the brain.Objective: The aim of this study was to check if there is a statistically significant relation between IGF-1 values in children with GHD with and ...

Background: Pseudohypoaldosteronism type II (PHAII), is a rare renal tubular disease with an autosomal dominant inheritance characterized by hyperkalemic, hyperchloremic acidosis and hyporeninemia. Mutations in WNK4 and WNK1 were found initially. Recently have shown that KLHL3 and CUL3 are also causative genes.Objective and hypotheses: Hypertension, an essential symptom of PHAII, manifest in adolescents and young adults. In the absence of family history ...

Background: Familial Hypocalciuric Hypercalcemia (FHH) type 1 is a benign condition of hypercalcemia with autosomal dominant inheritance caused by pathogenic variants in the calcium-sensing receptor gene (CASR). CaSR plays a crucial role in the regulation of calcium balance. Inactivating mutations in CASR result in altered calcium-sensing and inappropriate parathyroid hormone (PTH) release concerning the calcium concentration. Dysplasia Epiph...

Background-Aim: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders caused by defects in the steroidogenic pathway of the adrenal cortex. In their most severe forms, they produce adrenal insufficiency and virilization of external genitalia when involving the terminal enzymes of the cortisol and aldosterone synthesis pathway (21-hydroxylase (21-OHD, OMIM#201910) and 11-hydroxylase (11-OHD, OMIM#202010) deficiencies). Mutations of <e...

Background: Congenital hypopituitarism (CH) is a group of disorders characterized by deficiencies in one or more hypophyseal hormones and a marked variability in genotype-phenotype correlations. Central diabetes insipidus (DI) is caused by a decreased release of ADH and results in a variable degree of polyuria. Their association is normally found in congenital cerebral midline abnormalities, such as septo-optic dysplasia.Objectiv...

Background: Obese adults with normal glucose tolerance (NGT) but 1-h post load glucose (1 hPG)≧155 mg/dl have an increased cardiometabolic risk. In children, preliminary data suggest that 1hPG≧132.5 mg/dl might identify those at higher risk of type 2 diabetes.Objective and hypotheses: To assess whether NGT obese youth with 1hPG ≧132.5 mg/dl (High-NGT) have worse insulin sensitivity and secretion compared to obese youth with 1hPG &#60...
