Background: Boys with 21-hydroxylase deficiency (21-OHD) develop testicular adrenal rest tumors (TARTs) at a high percentage. TARTs may lead to testicular structure damage and infertility. Treatment consists of increasing the glucocorticoid dose to suppress ACTH or surgery when necessary.Objective and hypotheses: We present an adolescent with TART who was treated by testicular sparing surgery at the age of 11.Method: A 13 -year-old...

Background: Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterized by susceptibility to tumours including haemangioblastomas of retina and central nervous system, renal cell carcinoma and phaeochromocytomas. The disease is caused by mutations in the VHL tumour suppressor gene.Objective and hypotheses: We present an adolescent with VHL disease confirmed by genetic analysis which revealed the mutation p. A149P (PCC>GCC), which ...

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...

Prolactinoma is most common functioning pituitary adenoma(50%). However, there have been limited studies for prolactinoma in adolescents. Pituitary adenomas are uncommon in childhood and adolescence (<3% of childhood supratentorial tumors, 3–6% of all surgically treated adenomas). The aim of this study is to assess the characteristics of Korean adolescents with prolactinoma and their clinical course. This study is retrospective cohort study. Patients diagnosed with pr...

Introduction: The annual incidence of Langerhans cell histiocytosis (LCH) is 5 per million in admission with a diagnosis of isolated central diabetes insipidus (CDI) in children under the age of 15. Here, the process leading to the diagnosis of LCH at presentation with isolated CDI, imaging findings, and the sellar erosion, which has not been previously reported in the literature, will be discussed.Case presentation: A 4-year-5-month-old...

Background: Body weight has a close correlation with bone mass in humans and high fracture rates has been reported in both obese and underweighted individuals. It is not clear the role of bone marrow adiposity (BMA) and the IGF system in this process.Aim: The aim of this study was to analyze bone composition and BMA in obese and non-obese children/adolescents and correlate them with the expression of the IGF type-1 receptor (IGF1R) in peripheral lymphocy...

Aims: Do-It-Yourself Artificial Pancreas Systems (DIYAPS) represent a unique patient-initiated treatment in which commercially available and approved medical devices such as continuous glucose monitoring systems (CGMs) and insulin pumps are connected by an off-label algorithm, and are remotely controlled by open-source algorithms to automate insulin delivery. While these systems are co-created by the DIYAPS community, and access is open to everyone, users have...

McCune-Albright syndrome (MAS) is a rare disease defined by the triad of precocious puberty (PP), café au lait spots, and fibrous dysplasia (FD). There are only a few patients with MAS in Korean because of the rarity of this disease. We reported the various clinical and endocrine manifestations and genetic analysis of 14 patients with MAS in Korea. It is a retrospective cohort study of patients’ clinical data including about peripheral PP, FD. Also, treatment experie...

Background: Maternal triglycerides, fatty acids, and their metabolites together with sugars and metabolic intermediates may play a role in newborn outcomes. Furthermore, maternal amino acids, acylcarnitines, lipids and fatty acids and their metabolites are associated with cord C-peptide independent of maternal BMI and glycemia, highlighting the potential contribution of maternal metabolites to offspring outcomes. This study examined the associations of materna...

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...
