Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Introduction: Turner's syndrome (TS) is associated with several manifestations the most frequent being short stature and hypogonadism. Some authors (Nadeem, 2012; Bakalov, 2008) reported that individuals with TS have increased risk of fractures, but the etiology and mechanism of bone fragility have not been yet fully elucidated and may be exacerbated by hormonal factors (Cintron, 2017; Soucek, 2015). Bone densitometry (BD) through the emission of double en...

Introduction: Complete Androgen Insensitivity Syndrome (CAIS) is characterized by a complete external genitalia appearance and testicular development in 46,XY individuals harboring pathogenic allelic variants in the AR gene. Due to growing evidence regarding the low risk of germ cell tumors (GCT) in AIS. Prophylactic gonadectomy has been debatable in the CAIS management, mainly due to the absence of an accurate biomarker for GCT....

Introduction: Androgen Insensitivity Syndrome (AIS) is the most common cause of Differences of Sexual Development (DSD) in 46, XY individuals. It is an X-linked genetic disease caused by allelic variants in the Androgen Receptor Gene (Xq11-12). Methods: Patients with clinical suspicion of AIS performed hormonal serum measurements (LH, FSH, estradiol, testosterone) and molecular sequencing of the AR gene, including exons and the 5’UTR region. Psychosexual variab...

Context: Differences in sex development (DSD) represent a broad spectrum of conditions that can present at different ages to various healthcare professionals with different backgrounds.Design: This is a retrospective, observational cohort that includes all DSD subjects referred to a multi-professional DSD team over a period of 41 years (from 1980 to 2021).Participants: A total of 6...

Disorders of sex development (DSD) are a group of congenital developmental disorders in which the chromosomal, gonadal, or anatomical sex is atypical. The clinical diagnosis and management of DSD are difficult and complex because of the various aetiology and diverse manifestation. The project ‘Genetics of Human Disorders of Sexual Development’ is funded by Swiss National Science Foundation and fulfilled by the University of Geneva Medical School (Switzerland), the Me...

Background: The XX male syndrome – Testicular Disorder of Sexual Differentiation (DSD) is a rare condition characterized by a spectrum of clinical presentations, ranging from ambiguous to normal male genitalia. The project ‘Genetics of Human Disorders of Sexual Development’ is funded by Swiss National Science Foundation and fulfilled by the University of Geneva Medical School, the Medical Centers from Armenia, Poland and Ukraine. The goal is to identify mutation...

Background: The purpose of this study was to analyse characteristics and evaluate the effectiveness and safety of treatment with recombinant GH (rGH) in children with idiopathic short stature (ISS).Method: Patients (n=54) were evaluated prospectively. Treatment was received by 27 patients with ISS during 1 year. The administration was done by the accepted methodology. The effectiveness of treatment was evaluated based on change in growing speed,...

Central precocious puberty (CPP) may be secondary to congenital adrenal hyperplasia (CAH), due to 21-hydroxylase deficiency. CPP in CAH may be associated with elevated sex-steroid levels and possibly a decline in negative sex-steroid feedback after treatment initiation. We experienced the two family cases of the salt-wasting form of the CAH, complicated by CPP with early maturation of the hypothalamic-pituitary-gonadal axis in all patients from two families.<p class="abste...

Introduction: Congenital hyperinsulinism (HI) is the leading cause of persistent hypoglycemia in infants and children. It is a rare glucose metabolism disorder characterized by unregulated secretion of insulin that leads to hyperinsulinemic hypoglycemia (HH). Most cases are caused by mutations in the KATP-channel genes ABCC8 and KCNJ11. KATP-HI can be classified into two distinct histological forms: a diffuse form, in which all of the pancreatic β-cells a...
