Background: In hypogonadotropic hypogonadism (HH), hypophyseal follicle-stimulating and luteinizing hormones, normally released with GnRH stimulation, are detected low. Since kisspeptin (KP) is a strong stimulant of GnRH neurons, it is considered to have a role in HH aetiology. It may be hypothesized that abnormal plasma levels of KP are indicative of HH.Aim: Evaluation and comparison of plasma KP levels in boys of pre-p...

Background: Kisspeptins, ligands of G protein-coupled receptor 54 (GPR54) encoded by the KiSS-1 gene, have recently emerged as key players of the gonadotropic axis. It was found that KiSS-1/GPR54 system plays an important role in the neuroendocrine control of gonadotropin secretion, brain sex differentiation, puberty onset and fertility. It is important to know if the kisspeptin serum level could be used as a diagnostic criterion to the stage of puberty or impairment of it in ...

Background: Recently kisspeptins are considered as a key gatekeepers of the regulation of the gonadotropic axis.Objective and hypotheses: To investigate the impact of experimentally induced hypogonadism on kisspeptins signaling in androgen-dependent tissues and blood.Method: Wistar male rats (29 in total) were used. Rats were divided into four groups. Group 1 (control, prepubertal rats aged 2 months, n=7). Group 2 (control...

Introduction: Siberia traditionally belonged to iodine-deficient regions. Cessation of iodine prevention in the 1990-s promoted the increase of iodine deficiency disorders (IDD) in Siberia. For iodine prophylaxis now is used iodized salt, and iodine preparations.The Aim: To estimate the iodine deficiency, the prevalence of IDD and the effectiveness of iodine prophylaxis in the North of Krasnoyarsk territory.<p class=...

Introduction: There are the inconsistent data about a role cellular and humoral immunity in pathogenesis of type 1 diabetes mellitus.The aim: The aim of this research was to study features of the immune status and of the activity of metabolic enzymes in lymphocytes of blood in children with type 1 diabetes.Methods: Cellular and humoral immunity parameters were studied in 94 patient...

Background: young children with type 1 diabetes mellitus (DM1) have a tendency to recurrent hypoglycemia. Increased sensitivity to insulin in young diabetes patients may be associated with features of secretion of catecholamine, particularly adrenaline.The aim: to explore the basal levels of catecholamine (epinephrine, norepinephrine, and dopamine) in serum of young children with type 1 diabetes mellitus to identify of p...

Background: Mauriac's syndrome (MS) may occur in patients with poor controlled type 1 diabetes mellitus (DM1), with often ketoacidosis, episodes of hyperglycemia and hypoglycemia, under the dose insulin. MS characterized growth retardation and puberty delay, Cushingoid obesity, moon facies, protuberant abdomen, hepatomegaly with transaminase elevation, dyslipidemia. Now it is a rare syndrome, firstly described by Mauriac in 1930.<str...

Background: Prader-Willi syndrome (PWS) is a complex genetic disorder with implications on the endocrine and neurologic systems, metabolism, and behavior. Early in life, PWS is characterized by hypotonia and failure to thrive, followed by obesity and hyperphagia. Patients with PWS develop hypothalamic dysfunction which may lead growth hormone deficiency, hypogonadism, hypothyroidism, adrenal insufficiency and poor bone mineral density. Traditionally, obesity i...

Introduction: Diabetic ketoacidosis is a frequent reason for hospital admission of children with newly diagnosed diabetes and the most frequent cause for hospitalization of children with poorly controlled diabetes.Aim: To evaluate the frequency of diabetic ketoacidosis (DKA) hospitalization for pediatric patients and resources for its decrease.Methods: Subjects included children <19 years who hospitalized with DKA in the pediat...

Epiphysis inhibits formation and secretion of the most pituitary hormones and at the first turn gonadotropins. Frequency of epiphysis tumors, pinealomas in children is 2.5% of all verified tumors of brain. 75% of epiphysis tumors are malignant. Endocrinological disturbances can be the first signs of pinealoma. In 10% cases there is precocious puberty syndrome. A 2.5 year-old boy presented to the endocrinology department with an 16-month history of accelerated physical developm...
