Background: Prader-Willi Syndrome (PWS), due to loss of paternal gene expression on chromosome 15q11.2-13, is characterized by hypotonia, hypothalamic-pituitary dysregulation, abnormal respiratory drive, and hyperphagia. GH, often started in infancy, improves tone, body composition, and height. Concerns about sudden death in children with PWS started on GH, hypothesized secondary to worsening obstructive sleep apnea (OSA) from adenotonsillar hypertrophy, resulted in guidelines...

Background: Pycnodysostosis is a rare recessive condition with mutation in the cathepsin K gene, causing reduction in bone reabsorption resulting in abnormally dense and fragile bones. Characteristic features include deformity of the skull, maxilla causing craniofacial, dental abnormalities with skeletal changes and short stature. Growth hormone therapy has been attempted in a small group of patients with Pycnodysostosis to promote final adult height, however has not been show...

Introduction: Medical advances result in cure and life extension. Modern methods of oncological treatment lead to late endocrinological side effects.Objective of the study: The aim of the study was to assess the patients’ knowledge of possible result of chemotherapy and its long-term effects linked to gonadal dysfunction.Materials and methods: The survey covered a group of 92 (62 women) patients with hematologic neoplasms at t...

Background: Estrogen replacement is a treatment of choice for pubertal induction in adolescent girls with ovarian failure due to Turner syndrome (TS). Recently published data show, that prepubertal low dose estrogen replacement is more physiologic, and can optimize response to growth hormone treatment, pubertal timing, and improve cognition. The metabolic effects of such treatment regimen have not been fully investigated to date.Objective and hypotheses:...

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: 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...

Background: Prediction of the effectiveness of GH therapy in children with short stature is an important issue. Artificial neural networks (ANN) seem to be promising tool for this purpose, not requiring any assumption on functions linking independent and dependent variables.Objective and hypotheses: The aim of the study was to compare ANN models of GH therapy effectiveness, based on the data available at therapy onset with multiple linear regression (MLR...

Background: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of cytotoxic T-lymphocyte-associated protein 4 (CTLA4) gene, Fc receptor-like 3 (FCRL3) gene, Fas apoptotic inhibitory molecule 2 (FAIM2) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association of polymorphi...

Backgrounds and objectives: Low bone mass density is an important problem in survivors of childhood cancers. The aim of this study is to determinate the influence of factors on bone mass density (BMD) and the prevalence of abnormal bone turnover.Materials and methods: The evaluation was performed in 67 patients (64.18% boys and 35.82% girls) at least 1 year after therapy of solid tumours, aged 4–27 years (median 12.67). The following parameters were...
