Introduction: Growth failure is a common consequence in small for gestational age (SGA) children.Patients and methods: The growth patterns and serum insulin like growth factor 1 (IGF1) concentrations before and after the 1st year under GH treatment of 32 short stature SGA born children have been evaluated. In addition, we investigated the insulin like growth factor 1 receptor (IGF1R) exon 2 as a hotspot for IGF1R genetic alterations. It is of note that n...

Introduction: Premature thelarche is considered a benign condition of breast development in prepubertal girls. It usually resolves after a certain period of time.Materials and methods: A 1.5 year old girl was referred to the pediatric Endocrinology department due to breast development which appeared two months prior to the visit.Results: Upon clinical examination the patient had Tanner breast stage M2-3 bilaterally, but otherwise a...

Background: Risk of developing germ cell tumors (GCTs) in disorders of sex development (DSD) patients with karyotypes contain Y-chromosome or it’s material (Y) increase with age. The appropriate timing for prophylactic gonadectomy in these patients is still controversial.Aim: To analyze the gonadal tumor incidence and histological assessment of gonads in DSD (Y) patients who were treated in a single institution between 1997 and 03/2018.<p class=...

Background: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. It has been demonstrated that the ZnT family plays an important role in the synthesis and secretion of different hormones. Furthermore, ZnT8Ab (zinc transporter-8 autoantibodies) together with GADAb (glutamic acid decarboxylase antibodies), IAA (insulin autoantibodies) and IA-2Ab (islet antigen-2 antibodies) are markers of auto...

Background: The etiology of Autoimmune thyroid diseases (AITDs), including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT) is multifactorial and involves genetic and environmental factors. Family and population studies confirmed the strong genetic influence and inheritability in the development of AITD. Possible sex-related differences in overexpression of the cytotoxic T-lymphocyte antigen 4 (CTLA4) gene, peptidyl arginine deiminase 4(PADI4) gene, the fat mass...

Background: Turner syndrome (TS) is one of the most common chromosomal aberrations resulting from the total or partial absence of one of the X chromosomes in all or a portion of cells. The presence of genetic material of the Y chromosome in TS patients is a risk factor for the development of gonadoblastoma or dysgerminoma.Objective and hypotheses: The aim of this study was to detect the presence of fragments of the Y chromosome, which increase the risk o...

Background: X-linked AHC is a rare disorder of the adrenal cortex caused by mutations in the NR0B1 (DAX1) gene. NR0B1 (DAX1) encodes for an orphan nuclear hormone receptor which is expressed in the adrenal, gonad, hypothalamus, and pituitary glands. Hypogonadotropic hypogonadism (HH) is the most frequently observed puberty disorder (absent or delayed puberty) caused by mutations in the NR0B1 (DAX1) gene and is due to impaired gonadotropin synthesis a...

Background: Hypophosphatemic rickets (HR) is a group of rare disorders caused by excessive renal phosphate wasting. The dominant form of HR is X-linked HR (XLHR) caused by mutation in the phosphate-regulating endopeptidase gene PHEX. There is also autosomal dominant form of HR caused by mutation in FGF23 gene or rare autosomal recessive form caused by DMP1 mutation. The phenotype can vary from very delicate to severe bone disease.<p class="abstex...

Background: One of the crucial aspects of the management of disorders of sex development is the assessment of the risk of malignant transformation of a dysgenetic gonad.Objective and hypotheses: The PCR analysis of germ-cell risk factors as the presence of the TSPY gene may be helpful in decision making of an early gonadectomy.Results: We report a 46,Xdel(Y)p11.3 girl with gonadal dysgenesis, that was referred to the Depar...

Background: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene, the interferon induced helicase domain 1 (IFIH1) gene, the TSH receptor (TSH-R) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association...
