Introduction: McCune-Albright Syndrome (MAS) is a rare congenital disorder caused by post-zygotic activating mutations in GNAS gene. Due to the mosaic pattern of this disease, mutation abundance is frequently low in several tissues, including blood cells. The emergence of next-generation sequencing (NGS) methodologies has allowed the analysis of millions of DNA fragments simultaneously and independently, enabling detection of low mutation abundance. Aim: To es...

Background: Genetic causes of central precocious puberty (CPP) has been increasingly recognized, extending our knowledge of the triggering factors of human pubertal timing. Distinct etiologies remain to be elucidated in sporadic and familial cases. Methyl-CpG-binding protein 2 (MECP2) is a chromatin-associated protein that can activate or repress gene transcription, playing a role in neuronal maturation. It is encoded by MECP2 gene located at chromoso...

Background: Most published studies on 46,XY DSD focused on genetic findings without association with biochemical work-up.Objectives: To retrospectively analyze the clinical and genetic findings of a large cohort of 46,XY DSD patients.Methods: 285 non-syndromic 46,XY DSD individuals (192 sporadic and 89 familial cases) were studied. LH, FSH, testosterone (T), androstenedione (A) wer...

Background: Heterozygous mutations in the Aggrecan gene (ACAN) cause autosomal dominant short stature with bone age (BA) acceleration, and premature growth cessation.Objective and methods: To characterize the phenotypic spectrum, associated conditions and describe response to growth-promoting therapies, detailed clinical evaluation of 73 mutation positive individuals from 16 families different families with heterozygous ACAN mutations was perfor...

Introduction: Although the safety and effectiveness of recombinant human growth hormone therapy (rhGH) has been reported for several years, the level of consensus on the outcomes that should be reported is unclear. The aim of this systematic review is to study the frequency of reporting of these outcomes in children with GH deficiency (GHD).Methods: A systematic review was performed in Medline, Embase, Cochrane Central R...

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...

Introduction: McCune Albright Syndrome consists of at least 2 of the following 3 features: (1) polyostotic fibrous dysplasia (PFD), (2) Café au lait macules and (3) autonomous endocrine hyperfunction (eg, gonadotropin-independent precocious puberty). Other endocrine syndromes include hyperthyroidism, acromegaly, and Cushing syndrome.Case: 2 year old girl presented with severe hip pain, inability to walk and progressive deformity of right lower limb....

Background: Post renal transplantation, tubulopathies may occur as an effect of transplantation itself or secondary to the use of immunosuppressive regimes. This often requires administration of large doses of sodium bicarbonate and sodium chloride, resulting in poor compliance. Adult studies have shown the advantages of fludrocortisone in the treatment of severe tubulopathies post renal transplant. There is limited data in children. We report our experience from a tertiary pa...

Background: Stunting in children is a heterogeneous state. Many endocrine, somatic, genetic and chromosomal diseases are accompanied by stunting. It can adversely affect indicators of the final height of the child; therefore timely diagnostics and treatment stunting is very important.Objective and hypotheses: To carry out a retrospective analysis of case histories of children and adolescents with genetically determined types of short stature who admitted...

Introduction: Subcutaneous fat necrosis (SFN) of the newborn is an inflammatory disorder of the adipose tissue that rarely disease which may be complicated with potentially life-threatening hypercalcemia. The etiology of hypercalcemia was related to persistently elevated 1,25-dihydroxyvitamin D3 levels.Case: The case 47 days (length 0.3 SDS; weight −1.48 SDS) who presented sucking difficulty and debility duo to hypercalcemia with an init...
