Introduction: Delayed puberty (DP), affecting over 2% of adolescents, is defined as pubertal onset 2-2.5 SDs later than the general population. The most common underlying aetiology is self-limited DP (SLDP). However, this can be difficult to differentiate from the more severe condition congenital hypogonadotrophic hypogonadism (HH), especially on first presentation of an adolescent patient with DP. This study sought to elucidate phenotypic and genotypic discre...

Introduction: Diabetic neuropathy (DN) is a common complication of type 1 diabetes mellitus (T1D) with significant morbidity in adulthood. The association between DN with long term poor metabolic control is well established. However, acute painful DN may present early in the course of the disease and may be reversible.Case presentation: A female adolescent, aged 12 years, with a T1D duration of 9 months, presented with acute metabolic derrangement (HbA1c...

Background: Steroidogenic factor 1 (encoded by the NR5A1gene) is a transcriptional regulator of genes involved in gonadal development and steroidogenesis. Mutations in NR5A1 have been identified among the most frequently genetic causes of disorders of sex development (DSD).Objective: To report the phenotype of 31 patients associated with 17 novel and 9 previously described NR5A1 sequence varian...

Background: Hypophosphatemic rickets (HR) comprises a group of inherited forms of rickets characterised by renal phosphate wasting. Taking info account the latest advances in HR therapy, it now becomes of interest to better define the mutational and phenotypic spectra of disease.Objective and Hypotheses: The aim of this study was to clinically characterize and perform genetic analysis of 168 cases with HR.<p class="a...

Background: The hypothalamic–pituitary–adrenal (HPA) axis responds to several acute or chronic environmental stessors, including those of social stress.Objective and hypotheses: To assess the HPA axis acute response during mental stress and mobile phone call exposure in healthy adolescents through salivary cortisol measurements and to investigate the modulatory effect of baseline biochemical or low-inflammation markers during this response....

Background: Non Hodgkin lymphoma (NHL) is the fourth most common malignancy in childhood. Chemotherapy constitutes the first line treatment and may cause several endocrine side effects (growth retardation, hypergonadotrophic hypogonadism, bone mass loss and rarely secondary malignancy). In total of 1–2% of children may harbour thyroid nodules. The most common risk factors are: irradiation, female sex, iodine deficiency, puberty and past medical history of thyroid disease....

Background: The association of primary hypothyroidism and isosexual precocious pseudopuberty in females was first described in 1960 by Van Wyk and Grumbach. The unique elements that lead to the diagnosis are FSH-dominated sexual precocity with non advanced bone age in the presence of hypothyroidism.Objective and methods: Describe an 8.5 years old girl with hypothyroidism due to HT and clinical and hormonal features of Van-Wyk and Grumbach syndrome.<p...

Introduction: The PLIN1 gene encodes perilipin - a lipid droplet coat protein expressed in adipocytes where it inhibits basal and facilitates stimulated lipolysis. Mutations in PLIN1 have been described in several families with partial lipodystrophy, dyslipidemia and insulin resistance (partial lipodystrophy type 4, Familial, FPLD4). Herein we describe a novel heterozygous c.1210-1delG splicing variant in PLIN1 gene in three unrelate...

Background: GNRHR gene mutations are responsible for development to normosmic idiopathic hypogonadotropic hypogonadism (iHH) and known to be the most frequent cause of this condition. Nevertherless, the reported frequency of GNRHR mutations in iHH patients estimated to be as low as 3-6%.Objective: To evaluate the frequency of GNRHR gene defects in a heterogeneous group of Russian patients with iHH and described the p...

Objective: Compare HOMA-IR between obese and normal weight children.Methods: 292 children (156 females), BMI (≥0SD), Tanner stage 1/>2: 163/129, divided in four groups (Group 1: 0SD<BMI<2SD, Group 2: 2SD≤BMI<2.25SD, Group 3: 2.25SD≤BMI<2.5SD, Group 4: BMI≥2.5SD) were analyzed retrospectively from the medical records. Age, sex, fasting blood glucose and insulin as well as the ho...
