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: 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...

Keywords: Preterm newborn, Small for gestational age, Thyroid hormones, Thyroid-stimulating hormone, Thyroid dysfunctions, Thyroid function tests.Background: A common cause of neurodevelopmental impairment in children is congenital hypothyroidism, but can be preventable with adequate screening and proper management. Preterm newborns are more likely to have thyroid dysfunction, with small for gestational age (SGA) being a...

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<...

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 deficienci...

Introduction: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is a rare, autosomal disorder characterized by deficiency of cortisol and oftentimes aldosterone, elevated adrenocorticotropic hormone (ACTH), and excess androgen production. In a phase 2 study of adolescents with classic 21OHD, 14 days of treatment with the corticotropin-releasing factor type 1 receptor (CRF1) antagonist, crinecerfont, led to median percent red...

Introduction: Osteopetrosis (OP) is a rare genetic disorder that is characterized by abnormal osteoclast function resulting in dense bones and marrow failure. The only definitive cure for OP is stem cell transplantation (SCT). Hypercalcemia is a well described complication in children with OP undergoing SCT. This study describes the calcium profile and treatment modalities used to maintain normocalcemia in children with OP undergoing SCT.<p class="abstext"...

Background: Hormonal replacement in boys with congenital Hypogonadotrophic Hypogonadism (HH) as well as hormonal repair of bilateral cryptorchidism and micropenis remain a challenge in pediatric endocrinology.Methods: In the «REMAP» study ISRCTN13007297 eight neonates and infants, all with bilateral cryptorchidism in intra-abdominal position and micropenis (≤2 cm), with absence of neonatal male-mini puberty were treated for 3 months with ...

Background: Obesity in childhood and adolescence represents a major health problem of our century, and accounts for a significant increase in morbidity and mortality in adulthood.Objective and hypotheses: To investigate the effectiveness of a comprehensive and personalized plan of action in the prevention and management of overweight and obesity in childhood and adolescence.Method: 470 children and adolescents (mean age±SEM: 9...
