Background: The incidence of gonadal tumor development varies significantly between subsets of patients with disorder of sex development (DSD). In some female patients with Y chromosome too early gonadectomy is perceived as overtreatment.Objective and hypotheses: The aim of the study was to analyze the gonadal tumor incidence in DSD female patients with 45,X/46,XY or 46,XY.Method: 15 patients, managed at single institution between ...

Background: Mosaic Turner syndrome (TSM) commonly occurs in the form of 45,X/46,XX and 45,X/46,Xiq, although mosaicism including the presence of a Y chromosome has been well documented. It is associated with increased risk of gonadoblastoma (GB).Objective and hypotheses: To date, there are only six reported cases of TSM with a trisomy 18 karyotype, and only two of these were phenotypically female with 45,X, 47,XY+18 karyotype.Metho...

Background: Achondroplasia and hypochondroplasia are more frequent types of skeletal dysplasia. De novo mutations in the fibroblast growth factor receptor 3 (FGFR3) gene are the principal cause. More than 95% of the cases of achondroplasia result from a mutation G1138A (Gly380Arg). In hypochondroplasia we usually (50–70%) found the change C1620A y C1620G, N540K (Asn540Lys).Objective and hypotheses: We describe an skeletal dysplasia...

Background: Congenital generalized lipodystrophy (CGL) is characterized by the absence of most adipose tissue at birth due to an adipocyte differentiation block. For several forms of CGL, the underlying mutation and pathophysiological pathway has been identified. However, for many cases the genetic cause is still unknown.Objective and hypotheses: We report a patient with CGL who showed a complete absence of fat apart from protective fat pads in a postnat...

Background: We recently described that 27.8% of patients treated with recombinant human GH (r-hGH) using the easypod had an adherence (AD) rate of <85.7% i.e. missing one r-GH dose per week. Overall AD of all investigated patients during the first 2 years of treatment was generally high (mean 90.2%).Objective: To evaluate the importance of high AD rate of r-GH administration over the first 2 years of r-hGH treatment on growth velocity and increase of...

Background: Patients with mixed gonadal dysgenesis (MGD), whose prototypical karyotype is 45,X/46,XY may manifest complications characteristic of Turner’s syndrome. We here present a 10-year-old male with MGD who had coarctation of aorta. At birth, he was found to have hypospadias, bifid scrotum and cryptorchidism. Chromosomal analysis of lymphocytes revealed a karyotype of 46,X idic Y (23)/45,X (7). Left gonadectomy was performed in infancy and the removed gonad showed s...

Background: Disorders of sexual differentiation (DSD) at birth is a serious defect often seen in endocrinology. Diagnosis must be early to ask an etiologic diagnosis, choose the sex of rearing and effectively treat the disease.Objective and hypotheses: Search etiologies of sexual ambiguities and clarify the phenotypic characteristics.Method: This is a retrospective study of 180 sexual ambiguities hospitalized. All patients underwen...

Background: As well as acting on longitudinal growth, growth hormone (GH) also has a number of metabolic effects, and is involved in the regulation, functioning and development of the immune system.Aims: To evaluate the immune profile in GH-deficient children after 6 months’ GH treatment.Method: A total of 44 children were examined before and after a six-month course of treatment with rhGH (0.03 mg/Kg per day). Levels of IGF1 ...

Introduction: Kisspeptin is well known gatekeeper of puberty onset to date. However, several neuroendocrine factors are also discovered to be associated with puberty onset and, especially neuropeptide Y (NPY) and neurokinin B, participate in the neuronal network integrating reproduction. However, the interactions between neuroendocrine factors and the reproductive axis have not yet been fully explored. We report herein the expression profile of NPY gene and neurokinin B gene i...

Background: Autoimmune polyglandular syndrome type 1 (APS-1) is a rare disease associated with mutations in the autoimmune regulator (AIRE) gene and characterized by mucocutaneous candidiasis (CMC), hypoparathyroidism (HP) and primary adrenal insufficiency (AI). Two of these three components are required for diagnosis.Objective and hypotheses: To describe Russian patients in terms of clinical, genetic, and immunological parameters....
