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: Thyroid cancers are rare in childhood. ATA guideline (Pediatric section) has been applied in daily practice since 2015. It is very significant to accurately predict the risk in the management of differentiated thyroid cancer(DTC). For this purpose, we shared our single center-20-year-experience about the follow-up features and management of childhood and adolescent thyroid cancer. We aimed to evaluate the dynamic risk stratification (DRS) and the o...

Background: The sonic hedgehog pathway (SHH) regulates CNS development and mutations or abnormal expression of the SHH pathway genes have been identified in epithelial tumors. SHH pathway interacts with Wnt/β-catenin signalling. To date, CTNNB1/β-catenin mutations are the sole molecular abnormality found in adamantinomatous craniopharyngiomas (ACPs).Objective and Hypotheses: To analyze the expression pattern of SHH pathway genes in ACPs and its...

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...

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...

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...

Objectives: Anti-Müllerian hormone (AMH) is produced by Sertoli cells in the testicles and granulosa cells in the ovaries. Increased abdominal adipose tissue initiates metabolic and endocrine disorders and predisposes to polycystic ovary syndrome. AMH is used as a marker in PCOS. A decrease in AMH levels has been reported in adults with obesity and increased central adiposity. The purpose of this study was to assess the serum AMH level and related factors...

Background: Body image (BI) is subjective picture of one’s own physical appearance established both by self-observation and by noting the reactions of others. Different BI scales used for screening of the Binge Eating symptoms that strongly linked to obesity.Objective and hypotheses: We supposed to get differences in the own body image perception in overweight and lean children.Method: BI questionnaire (BIQ) and own body satis...

Purpose: Therapeutic goals in the adolescent male with hypogonadotropic hypogonadism(HH) are virilization, optimal adult height, normal bone mass, body composition, psychosocial development, and fertility. Until recently, only testosterone was used to treat adolescent males with HH. However, this treatment did not cover all treatment goals and adverse effects on fertility were reported. Therefore, gonadotropin therapy can be used in addition to testosterone in...

Introduction: Ceratonia siliqua L. (CS) is from the legumes (Fabaceae) family, and different forms such as carob extract and flour are preferred by parents because it is a natural sweetener and a source of vegetable carbohydrates. CS is rich in polyphenols and flavonoids. When we questioned histories of the cases of early puberty and puberty variants who applied to our clinic, we noticed long-term and regular use in some cases. We planned to experimen...
