Central precocious puberty (CPP) may have endocrine and metabolic implications in adulthood. Long-term effects may be associated with the underlying neuroendocrine dysfunction leading to CPP, the GnRH analogue (GnRHa) therapy, or both. Data are conflicting on the long-term risk of polycystic ovarian syndrome in both treated and untreated women. Clinical hyperandrogenism has been more frequently reported in CPP women than in controls, with no significant difference between GnRH...

Patients with type 1 diabetes (T1D) and their caregivers continue to face the challenge of maintaining blood glucose levels in the near-normal range, preventing sustained hyperglycemia associated with long-term microvascular and macrovascular complications, and avoiding recurrent episodes of hypoglycemia, especially at young ages when they can adversely affect cognitive function. In a follow-up to the Diabetes Control and Complications Trial, the Epidemiology of Diabetes Inter...

Background: Adolescent polycystic ovary syndrome (PCOS) may be difficult to distinguish from pubertal changes and diagnosis remains a challenge.Objective and hypotheses: To investigate the value of different biochemical parameters for the diagnosis of PCOS and also to assess the prevalence of non-classical congenital adrenal hyperplasia (NCCAH) among adolescent girls referred for clinical symptoms suggesting PCOS.Method: Retrospect...

Introduction: Hypoglycemia is a significant cause of morbidity in children, yet is challenging to diagnose and treat due to its heterogeneity.Aim: To describe the diagnoses and clinical characteristics of children with hypoglycemia referred to a tertiary pediatric center.Methods: This retrospective study included 155 children (86 males, aged 0-18 years) diagnosed with hypoglycemia ...

Background: A basal 17-hydroxyprogesterone (17-OHP) plasma level of 6.0 nmol/l was suggested as a threshold for the diagnosis of non-classical congenital adrenal hyperplasia (NCCAH), particularly in children presenting with precocious pubarche (PP).Objective: The present study aimed to determine if this threshold could lead to underdiagnosis of NCCAH.Method: In a retrospective study the cohort of pediatric patients (n=145,...

Background: Hypoglycemia etiology in children is heterogeneous and varies by age. Both growth hormone (GH) and cortisol deficiencies may present with hypoglycemia; the latter may result in an adrenal crisis that may be fatal.Objectives: To evaluate responses of cortisol and GH to spontaneous hypoglycemia in infants and children, and to assess the rate of true cortisol deficiency in children, defined as cortisol<500 nm...

Background: Data on the course of puberty and pubertal growth in boys with Type 1 diabetes (T1D) are sparse.Objectives: To study the course of puberty, pubertal growth and final height in boys with T1D as well as possible factors affecting these.Methods: In this retrospective longitudinal study, 68 boys diagnosed with T1D between 1996-2009 who were pre-pubertal at diagnosis and had...

Background: Thyroid hormone resistance (THR) is a rare genetic disorder that may be caused by thyroid hormone (TH) cell transporter defects or metabolism defects, but most cases are caused by an inherited mutation in the TH receptor beta (THRB) gene. The reduced responsiveness of target tissues to TH is characterized by elevated TH and a normal or elevated thyroid-stimulating hormone (TSH) level. Differentiating between THR and TSH-producing pituitary...

Background: Gonadotropin-releasing hormone (GNRH) and its receptor (GNRHR) are central regulators of puberty. Loss-of-function mutations of the GNRH-GNRHR signaling pathway are associated with congenital hypogonadotropic hypogonadism, but no mutations were reported so far in patients with central precocious puberty (CPP). Animal data demonstrate the importance of microRNAs in pubertal timing regulation. Among others, miR200b regulates Gnrh1 gene expression in GnRH neu...
