Introduction: Physiological pubertal gynecomastia is common in adolescents aged 13-14 years. Most physiological pubertal gynecomastia regresses spontaneously within 1-2 years. In studies: If it lasts more than 2 years, if prepubertal has started, endocrine evaluation is recommended. Sex differentiation disorders or genital abnormalities such as increased aromatase activity, adrenal/testicular neoplasia, partial androgen insensitivity syndrome and Klinefelter s...

Few treatments for type 2 diabetes (T2D) and obesity achieve meaningful long-term weight-loss and are often accompanied by nausea and vomiting. Thus, there is a critical need for a new generation of obesity medications that provide glycemic control with enhanced hypophagic response without nausea. Our group has developed and tested two new monomeric chimeric peptides against a novel target for obesity treatment concomitant with T2D in the form of dual agonism of the anorectic ...

Autosomal dominant DICER1 mutations are among the causes of early-onset familial cancer. DICER1 mutation has been shown in pleuropulmonary blastomas as well as ovarian tumors, thyroid, parathyroid, pituitary, adrenocortical and testicular tumors. It is important to be aware of the risk for the development of other cancers in the follow-up of these cases.Cases: Case-1: Previously known to be healthy 8,5-year-old girl presented with compla...

Background/aim: The PTEN hamartoma tumor syndrome (PHTS) is an overgrowth syndrome caused mainly by germline mutations in the tumor suppressor PTEN. Patients are predisposed for the development of malignant and benign tumors. Children and adolescents with PHTS frequently develop single or multiple lipomas. PTEN antagonizes the phosphatidylinositide3-kinase/AKT/mechanistic target of rapamycin (PI3K/AKT/mTOR) pathway, which promotes proliferation and differentiation in ...

Context: Quality of survival (QoS) is frequently impaired in childhood-onset craniopharyngioma (CP) patients due to sequelae caused by the hypothalamic syndrome. The debate, whether primary hypothalamic involvement (HI) has apriori prognostic impact or surgical hypothalamic lesions (HL) determine outcome, is controversial. Accordingly, we analyzed, whether CP patients at high risk for hypothalamic obesity due to primary HI of anterior and posterior hypothalamic structures bene...

Background: Prader-Willi Syndrome (PWS), due to loss of paternal gene expression on chromosome 15q11.2-13, is characterized by hypotonia, hypothalamic-pituitary dysregulation, abnormal respiratory drive, and hyperphagia. GH, often started in infancy, improves tone, body composition, and height. Concerns about sudden death in children with PWS started on GH, hypothesized secondary to worsening obstructive sleep apnea (OSA) from adenotonsillar hypertrophy, resulted in guidelines...

Introduction: Kisspeptin is a neuropeptide, encoded by the KISS1 gene, which acts upstream of gonadotropin-releasing hormone (GnRH) neurons and also has a critical role for maturation and function of the reproductive axis. Inactivating mutations of its receptor (KISS1R) cause normosmic isolated hypogonadotropic hypogonadism (IHH). In this report, we aim to present three siblings who have IHH due to novel compound heterozygous KISS1R mutation.Cas...

Background: To the best of our knowledge, no study has been conducted to assess the impact of 21 hydroxylase deficiency and hidrocortisone treatment on electrocardiographic measures in children with 21-hydroxylase-deficient congenital adrenal hyperplasia.Objective and hypotheses: The purpose of this study is to compare the12-lead electrocardiographic measures such as PWd, QT interval, QTd, Tp-e interval, Tp-e/QT and Tp-e/QTc ratio in patients of 21-hydro...

Background: Septo-optic dysplasia (SOD) is an important cause of hypopituitarism, although less common than multiple pituitary hormone deficiency (MPHD). Children with optic nerve hypoplasia (ONH) are at risk of hormone and neurocognitive disturbances.Objective and Hypotheses: We describe clinical and neuroradiological findings of these three overlapping conditions, aiming to understand their pathophysiology.Method: Retrospective a...

Background: Insulinomas are extremely rare tumors in children and an uncommon first manifestation of the MEN1 syndrome. An early clinical and genetic diagnosis is very important for the appropriate medical assessment and family counseling. In children, insulinomas are usually benign tumors with only a few reports of malignant cases.Objective and hypotheses: To investigate clinical features, genetic and morphological characteristics of 12 children with pr...
