Introduction: Noonan syndrome (NS) is a relative frequent genetic disorder, mainly characterized by dysmorphic face features, congenital heart defects and short stature. Though delayed pubertal development has been described in both sexes, the physiopathological root remains unclear. This study aims at characterizing puberty development in Noonan syndrome.Materials and Methods: The study population included 111 individuals with a molecul...

Introduction: Precocious pubarche (PP) is characterized by the early development of pubic hair and clitoral enlargement in girls. While commonly attributed to adrenal-related causes, such as congenital adrenal hyperplasia or adrenal tumors, ovarian sources are infrequent etiologies. In this report, we present a clinical case of a young girl with PP due to a rare source.Case Report: A 1.7-year-old girl presented with the ...

In CAH due to 21-OH deficiency, GH treatment combined to GC and MC replacement is still considered to be experimental. We present a patient who has benefited from such treatment. A baby girl was born in term with clitoromegaly and manifested with salt loose at neonatal period. Low serum morning cortisol and sodium with high potassium and 17-OH levels were found resulted in the clinical diagnosis of CAH. The karyotype was 46,XX. Prednisolone and DOXA, the only available hormone...

Background: Several studies found a high prevalence of sleep disorders in PWS patients. It is assumed that Prader-Willi Syndrome (PWS) patients are at a high risk of sleep disordered breathing, such as obstructive sleep apnea (OSA), because of their childhood obesity, associated with muscle hypotonia, leading to upper airway collapse.Objective and hypotheses: We studied a group of PWS children (genetically confirmed, non-GH-treated) who performed complet...

Objective: To characterise clinical presentation of congenital isolated ACTH deficiency.Methods and results: Clinical and anthropometric data were obtained. Biochemical liver function parameters, blood glucose, insulin, TSH, free thyroxin (FT4), GH, cortisol, and ACTH levels were analyzed. POMC and TBX19 genes were analysed by Sanger sequencing. The girl was born at full-term with normal weight and length. The parents are cousins. At birth cra...

Background: Diamond–Blackfan anemia (DBA) is an inherited bone marrow failure syndrome, which presents with anemia in early infancy. Survival depends on blood transfusions, which in consequence lead to iron overload (IOL). The most common complications of IOL are hepatic cirrhosis, endocrinopathies and cardiomyopathy.Results: We present the case of 17 years old girl with DBA and IOL-associated endocrinopathies. Her treatment consists of multiple blo...

Background: Steroidogenic Factor 1 (NR5A1/SF-1) is essential for the development and function of human sex and steroid organs. Variants of SF-1 lead to a broad spectrum of phenotypes including adrenal insufficiency and differences of sex development (DSD), but data on the whole picture of phenotypes in individuals with SF-1 variants are currently lacking. We aim to investigate the phenotype of individuals with SF-1 variants in a large interna...

Background: Overweight (OW) and obesity in paediatric population has been shown to be associated with an increase in prevalence of insulin resistance and type 2 diabetes (T2D) in youth.Objective and hypotheses: The aim of this study was to assess the efficiency and safety of metformin use in combination with lifestyle changes or alone for weight management in OW and obese (OB) children and adolescents.Methods: Study included 145 10...

Objective: Most children with short stature remain without an etiologic diagnosis after extensive clinical and laboratory evaluation and are classified as idiopathic short stature (ISS). This study aimed to determine the diagnostic yield of a multigene gene analysis in children classified as ISS.Design and Methods: We selected 102 children with ISS and performed the genetic analysis as part of the initial investigation. ...

Introduction: The majority of children with short stature are classified as ISS by the absence of findings that could elucidate the cause of their growth impairment. Several monogenic defects have already been identified in children with ISS, but the candidate gene approach is not feasible when there are no specific findings to guide a specific genetic test.Objective: To evaluate the diagnostic yield of a targeted gene p...
