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...

Children diagnosed with adrenocortical tumors (ACT) have variable prognosis depending on disease presentation at diagnosis. Available therapeutic options render excellent outcome for a subset of patients, but limited improvement in the survival of those diagnosed with non-localized/advanced disease. ACT DNA methylation was recently demonstrated to be a robust and independent prognostic biomarker. Aiming to identify potential therapeutic targets for these children, we compared ...

Background: overexpression of the oncogene Yes-associated protein 1 (YAP1), a Hippo pathway target, associates with increased cell proliferation in some human cancers. There is not data on adrenocortical tumors (ACT). YAP1 is a potential target of Wnt/β-catenin pathway, which plays an important role in ACTs.Objective and hypotheses: to evaluate the role of YAP1 and its interaction with the Wnt/β-catenin pathway in ACT.Met...

Background: Impairment of the chromatin remodeling factors ATRX and DAXX and telomeres abnormality play a role in cancer biology, influencing the clinical outcomes. However, their roles in adrenal tumorigenesis require broader investigation.Aim: To evaluate ATRX and DAXX genotype and expression, telomere length, and the alternative lengthening of telomeres (ALT), as well as their clinical significance, in primary adrenoc...

Aim: To uncover a feasible tumor expression prognostic signature and potential therapeutic targets for children with pACT.Methods: Tumor RNAseq from 53 pACT children (70% girls, median age: 1.7yrs) was performed (Illumina). Using a robust, state-of-the-art, differential gene expression analysis pipeline, differentially expressed genes (DEGs: adjusted P<0.05 and |log2 fold-change|>1) were identified (DESeq2...

Background: Leprechaunism, also known as Donohue syndrome, is due to a severe congenital insulin-resistance, with prenatal and neonatal growth retardation, typical dysmorphic features, glycaemic dysregulation with hyperinsulinism and hyperandrogenism.Objective and hypotheses: These patients have a poor prognosis with death in the first year of life.Method: We report the case of a newborn (35.4 weeks) with severe fetal growth restri...

Background: Daily r-hGH injection has been safely and effectively used in paediatric patients with GHD for more than 30 years. However, little information is available describing the burden and life impacts experienced by paediatric patients related to daily r-hGH injections.Objective: To identify the burden and impacts of a daily r-hGH injection regimen on the lives of paediatric GHD patients.Methods: A retrospective meta-analysis...

Introduction: Heterozygous familial hypercholesterolemia is as frequent as 1: 200-500, and the mortality risk is four times more than unaffected children.Nutritional therapy in addition to physical activity can help but is not enough to avoid later morbidity and mortality. Stations have shown efficacy in children, but we do not have enough data for long term safety.Aim: to compare tow regimens of therapy using rosuvastat...

Introduction: The National Registry of Civil Status through circular 33 of February 24, 2015 instructed the guidelines for the allocation of a sex through an inscription on the Civil Registry of Birth for intersexual minors.Objective: To create clinical and medical awareness on the importance of making an accurate diagnosis of Congenital Adrenal Hyperplasia CAH in order to avoid adverse effects due the omission of the due diligence by violating of the pr...

Healthcare professionals (HCPs) receive adherence information on patient Saizen® recombinant human growth hormone (r-hGH) treatment via data wirelessly transferred from the easypodTM electromechanical delivery device to the web-based eHealth platform easypodTM connect. In order to empower patients and caregivers with this information and to provide educational tools, the growlinkTM mobile app is being ...
