Background: Accurate prediction of responsiveness to growth hormone (GH) therapy is an important issue. The 1st year response to treatment is regarded as significant predictor of the attained final height. Neural networks are techniques of machine learning which do not require any assumptions and preprocessing of data, contrary to linear regression models.Objective and hypotheses: The aim of the study was to predict height velocity (HV) during 1st year o...

Introduction: Since 1960, enlarged polycystic ovaries associated with hypothyroidism, delayed bone age and precocious puberty are recognized as Van Wyk and Grumbach syndrome. Although it is rare entity, it should be considered in differential diagnosis of the enlarged polycystic ovaries.Case: An eleven-year-old girl was presented with sudden onset of abdominal pain and vomiting. A large mass with multiple cysts was seen ...

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases caused by a deficiency of enzymes responsible for the steroidogenesis. The most common cause is 21-hydroxylase deficiency. There are three forms of CAH due to 21-hydroxylase deficiency: the classic form with salt loss, the classic virilizing and the non-classical form. In pediatric age, CAH is most often manifested by masculinization of the genitals of female newborns, adrenal crisis or premature p...

Background: Children living with paediatric endocrine conditions in resource-poor countries experience inequitable rates of preventable mortality and morbidity. Reducing preventable mortality will help member states committed to delivering on the United Nations’ Sustainable Development Goals 3.2.1, 3.2.2 and 3.4. CLAN (Caring & Living As Neighbours) has been improving health outcomes for children living with CAH in resource poor countries since 2004,...

According to current recommendations, children with height SDS <-3.0, normal growth hormone (GH) peak in stimulation tests (stimGH) and severe IGF-I deficiency (IGFD) may be diagnosed with primary IGFD and treated with recombinant IGF-I. The need for direct confirmation of GH insensitivity is a matter of discussion. On the other hand, children born small for gestational age (SGA) with no catch-up growth are qualified to GH therapy despite normal GH secretion. The fact that...

Background: Tumor necrosis factor alpha (cachexin) is a cell signaling cytokine involved in systemic inflammation process. It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. The primary role of TNF alpha is the regulation of immune cells. TNF, being an endogenous pyrogen, is able to induce fever, apoptotic cell death, an...

Prediction of growth hormone (GH) therapy effectiveness in children with short stature is an important issue for optimizing its course. Recently, our research group has published prediction models derived with neural networks. The main predictors of final height (FH) in our model were: patient’s height SDS at therapy onset, pre-treatment change of height SDS (HSDS V0) and pre-treatment IGF-I and IGFBP-3 secretion but not the results of GH stimulation tests; the...

Prediction of poor response to growth hormone (GH) therapy in children with short stature is an important issue for personalized approach to treatment. Recently, our research group has published prediction models derived with neural networks. The main predictors of final height (FH) in our model were: patient’s height SDS at therapy onset (H0SDS) and pre-treatment IGF-I and IGFBP-3 concentrations but not the results of GH stimulation tests; pre-treatment growth...

Introduction: Human ovary is commonly the target of an autoimmune attack in cases of organ- or non-organ-specific autoimmune disorders. Hashimoto’s thyroiditis (HT) is likely to be associated with ovarian dysfunction and diminished ovarian reserve. The classical hormonal test assessing ovarian reserve as early follicular phase serum levels of FSH, inhibin B and estradiol (E2), which are interdependent, and the calculation of the number of antral follicles by transvaginal ...

Introduction: Zinc homeostasis is regulated by ZnT and Zip zinc transporters. Zinc transporter 8 (ZnT8) is localized in insulin containing secretory granule membrane and transports zinc from the cytosol into the vesicles. ZnT8 was identified on peripheral lymphocytes, in subcutaneous adipose tissue, in a pancreatic β-cells and extra-pancreatic endocrine glands including pituitary, adrenal and thyroid. Autoantibodies to the ZnT8 are detected in the majority of type 1 diabe...
