Background: Mild TSH elevations are frequently observed in obese patients, in the absence of any detectable thyroid disease.Aims and objective: To evaluate possible causes for the raised TSH levels and to verify possible biochemical and clinical consequences of this condition.Methods: We evaluated 779 (325 males/454 females) obese children, chronological age 14.38±2.56 (range 5.25 to 18.50), height SDS 0.27±1.04 (range &#...

Introduction: Prolonged evolution of an untreated hypothyroidism can lead to thyrotropic cell hyperplasia, which could be indistinguishable from a pituitary macroadnoma on resonance. Differential diagnosis is very important since it allows to avoid aggressive therapeutic behaviors.Case report: We show a 3-year-old girl who, in the context of a study due to psychomotor retardation, borderline head circumference and coarse features, presented in magnetic r...

Objectives: - To establish the main factors on which a good response to GH treatment depends. - To study the optimum adherence values. - To study the impact of the loss of adherence in the treatment with GH.Materials and Methods: This is a non-interventional, retrospective observational study, by reviewing medical records of patients undergoing GH treatment for at least 2years due to GHD or SGA. Patients received treatment with Saizen&#1...

Background: Ectopic ACTH-producing tumors rarely occur in children, with <1% of all adolescents with Cushing Syndrome (CS). Many cases of ACTH-secreting ectopic neuroendocrine tumors (NETs) are reported in literature. In most patients, tumors secrete corticotropin-like peptides and/or corticotropin releasing factor (CRF)-like peptide, which stimulate cortisol hyperproduction.Background: Ectopic ACTH-producing tumors r...

Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...

Background: It is well known that growth hormone (GH) brings about several effects, involving bone, body composition, lipids and glucose homeostasis. However, the complex interplay between these parameters is rather poorly studied in children with childhood-onset-GH deficiency (CO-GHD).Objective and hypotheses: To investigate lipids, adipokines (leptin- adiponectin- resistin) and glucose homeostasis and their relationship with bone and body composition i...

Despite significant advances in the medical management of childhood diseases, glucocorticoids (GCs) continue to be the mainstay of therapy for numerous serious conditions, including hematological malignancies, Duchenne muscular dystrophy (DMD) and inflammatory disorders. In order to understand the natural history of bone development in GC-treated children, a pan-Canadian longitudinal observational research study called "STOPP" (STeroid...

Catch-up growth (CUG) is characterized by a period of supranormal height velocity following a transient period of growth inhibition. The two classical hypotheses on the mechanism are the neuro-endocrine hypothesis (a central mechanism that would recognize the degree of mismatch between actual size and target size) and the growth plate hypothesis (local regulation of growth according to a preset cellular program of senescence, characterized by decreasing growth proliferation ra...

Study of the histopathology of human type 1 and 2 diabetes through the national pancreatic organ donor (nPOD) consortium has yielded interesting new insights that should also aid us in developing improved therapeutic approaches.1. When insulitis is observed, it usually shows a predominance of CD8 T cells, some of which are autoantigen specific (see also Coppieters et al. JEM 2012). It will be therapeutically challenging to remove/prevent CD8 mem...

Background: Cardiovascular disease (CVD) is the major cause of mortality in diabetes mellitus type 1 (T1DM). Dyslipidemia will increase this risk. Several guidelines have been published, how to treat dyslipidemia in T1DM, yet some studies have shown that the number of patients who are treated according to these guidelines is low.Objective and hypotheses: To investigate the frequency of dyslipidemia in children and adolescents with T1DM and if they are tr...
