Background: The GH-IGF system plays an important role in strength gain. Some studies suggest that Zinc, Magnesium and Pyridoxine (ZMA) supplementation could increase GH/IGF and testosterone levels in young subjects. This hypothetical increase could lead to significant changes in body composition. ZMA is a very popular supplement, easily found in specialty stores, and it is presumed to increase GH, IGF-I and testosterone levels. However, studies are divergent regarding its effi...

Background: Exercise programs are related to the anabolic function of GH/IGF-I axis.Objective and hypotheses: To analyse IGF-I, IGFBP-3 and ALS serum concentrations in adolescent swimmers at different stages of training season, and compare them with physical performance and body composition.Method: Nine male athletes, aged 16–19 years, who trained regularly throughout the season, were studied. IGF-I, IGFBP-3 and ALS were recor...

Introduction: The relationship between sports intensity and growth has become a concern in teenagers. Changes in the GH/IGF1 axis have been studied as biomarkers for training intensity in adolescents; however, reports on the effects of physical effort on GH and IGF1 levels are discordant and studies on GH and IGF1 responses in combat sports are scarce.Aim: To investigate the effects of a Jiu-Jitsu training session on serum IGF1 and IGFBP3 concentrations....

The pituitary gland dynamically remodels during key timepoints of life to meet the prevailing endocrine demands of the organism. Mechanisms underlying this plasticity remain poorly understood. In particular, it is not clear how the pituitary stem cells are involved and biologically behave during pituitary remodeling processes. Indeed, pituitary stem cells remain highly enigmatic regarding cellular complexity, regulatory circuits, niche make-up and functional role. In our studi...

The transition phase is the period from the end of puberty until achievement of full adult maturity. We report the results from 45 patients with pituitary deficiency (15-24.9years), 28 (16males) with congenital insufficiency (G1) and 17 (10males) with acquired disease (G2), evaluated at the end of GH therapy. All cases had confirmed GH deficiency; 89.2 % of cases from G1 had multiple pituitary deficiencies (TSH 23/28, LH/FSH 19/28, ACTH 15/28 and Prolactin 3/28), 94.1 &#37...

Introduction: Hyperandrogenism is a common presenting complaint during the transition period; however, clinical, hormonal and metabolic parameters in these patients have not been yet adequately characterized.Objective: To evaluate the disease-related history, clinical presentation and biochemical parameters in patients diagnosed during this period with nonclassic congenital adrenal hyperplasia (NCCAH) due to 21α hydroxylase deficiency and patients w...

Background: Although a large number of publications show a high prevalence of Metabolic Syndrome (MS) during childhood, to date, there is no uniform definition for evaluating this condition in children and adolescents. In the pediatric population, there are difficulties for characterizing this condition and the various criteria used might lead to underdiagnosis. In recent years, the triglycerides/HDL (TG/HDL) ratio has been proposed as a new marker.Objec...

Background: Aortic sized index (ASI) defined as aortic root size/body surface area (BSA) is used to provide information on dissection risk in Turner Syndrome (TS). There are multiple equations for estimation of BSA. The impact of using a different BSA equation for calculation of ASI is unknown.Method: We calculated BSA of 114 TS girls from 2273 outpatient visits using Dubois, Mostellar, Haycock, Gehan, Boyd and Furqan formulae. BSA estimation with Dubois...

Introduction: Precocious pubarche (PP) is characterized by the early development of pubic hair and clitoral enlargement in girls. While commonly attributed to adrenal-related causes, such as congenital adrenal hyperplasia or adrenal tumors, ovarian sources are infrequent etiologies. In this report, we present a clinical case of a young girl with PP due to a rare source.Case Report: A 1.7-year-old girl presented with the ...

Background: Pediatric bone marrow transplantation (BMT) can lead to endocrine dysfunctions due to common pre-operative regimens involving chemo and radiotherapy.Objective and hypotheses: To evaluate the prevalence an time-of-onset of endocrine dysfunctions after BMT in children and adolescents.Method: A retrospective cohort-study design was performed. The inclusion criteria were: <18 years of age at the time of their allogenic ...
