Background: The prevalence of childhood type 1 diabetes mellitus (T1DM) is increasing and the age at presentation is falling. Late presentation with diabetic ketoacidosis (DKA) is more common in younger children who are at increased risk of cerebral oedema.Objective and hypotheses: To describe the clinical presentation of new onset T1DM to our centre and report time to diagnosis, incidence of DKA, requirement for intensive care and complications.<p c...

Background: Childhood obesity is considered to be an epidemic in developed countries that can negatively affect children’s health and psychology.Aims and objectives: To investigate the nutritional and environmental factors that lead to the presence of childhood obesity and its complications.Methods: A total of 949 students, 3–12 years old, living in Sparta–Greece, have participated in our research. Their lifestyle an...

Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

Background: Normal thyroid function is necessary for the optimal growth promoting effects of GH. Changes in the hypothalamic-pituitary-thyroid (HPT) axis following GH have been reported in subjects initially thought to be euthyroid. A specific group of patients, children with Prader-Willi syndrome (PWS), are thought to have a ‘vulnerable’ HPT axis.Objective and hypotheses: To evaluate the impact of paediatric GH therapy on thyroid hormone statu...

Context: Puberty timing is highly heritable. Recent genome-wide association studies, comparing timing of menarche in girls to timing of voice-break and facial hair in boys, revealed a largely overlapping genetic architecture of female and male pubertal timing. However, it is also known that genetic heterogeneity between sexes exists for some loci.Objectives: We hypothesized that self-reported relative parental pubertal t...

Introduction: Cryptorchidism has usually been managed using a surgical approach, with little attention to the underlying pathophysiology.Objectives: To assess gonadal function before treatment in prepubertal boys with cryptorchidism.Methods: In a cross-sectional study we reviewed all clinical charts of patients encoded with the diagnosis of cryptorchidism in the database of a paediatric tertiary hospital, between 2000 and 2017. Inc...

Background: VRS-317, a novel fusion protein of rhGH exhibiting delayed clearance, serum half-life generally >100 h, and potential for once monthly dosing, was previously evaluated in a 6-month phase 1b/2a study of weekly, twice monthly or monthly dosing (5.0 mg/kg per month) in prepubertal GHD children (n=64).Objective and hypotheses: We evaluated whether increased VRS-317 dose from 12 to 18 months can offset the decrease in height velocitie...

Aim: Case report of an 18-month-old child with a background of vitamin D dependent rickets type 1(VDDR1)], due to a mutation of CYP27B1 (c.1319_1325dup and c.335C>T: compound heterozygote).Methods: Presentation of the case and the management of hypocalcemia as well as the complications of follow-up.Results: The patient presented at the A&Es of the 2nd Department of Pediatric...

Background: Initiation and progression of puberty requires concerted action of activating and inhibiting factors. Recently, cases of central precocious puberty have been linked to loss-of-function mutations of makorin RING-finger protein 3 (MKRN3) indicating a pivotal inhibitory role of MKRN3 on GnRH secretion.Objective and hypotheses: To investigate peripubertal circulating MKRN3 levels in healthy boys.Method: Healthy boys (n<...

Background: Maternal obesity is known to have many detrimental effects on pregnancy. Bariatric surgery represents the most efficient therapy for severe obesity. Although it is known to positively impact many pregnancy outcomes, bariatric surgery can disturb fetal growth due to nutritional deficiencies.Objective: We aim to examine the repercussions of bariatric techniques on fetal growth, and to evaluate the risk of deliv...
