Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...

During the pandemic, an increase in the cases of premature thelarche consultations was observed. Our group published a series in 2021 of 75 cases. This effect could have been caused by an increase in body fat mass in girls, suggesting a “trigger effect” in the activation of the gonadal axis, causing an increase in the number of cases of early puberty (SEEP Oviedo 2022). AMH has been correlated as a predictor of the moment of menarche (doi: 10.1515/jpem-2014-0521)</...

Background: Sexual maturation is closely linked to growth, suggesting common pathways between the reproductive development and the growth hormone/insulin-like growth factor-I (GH/IGF-I) axis. IGF-I bioavailability is regulated by Pregnancy associated plasma protein-A (PAPP-A), Pregnancy associated plasma protein-A2 (PAPP-A2) and Stanniocalcin 2 (STC2). A large genome-wide association study (GWAS) identified PAPP-A, PAPP-A2 and STC2 to represent loci strongly a...

Background: Growth in infancy is considered primarily to be regulated by nutrition and insulin, whereas less is known about the influence of IGF-I, reproductive hormones and other factors of importance. Recently, paternally inherited genetic defects of DLK1 (Delta-like 1 homolog) were found in girls with central precocious puberty (CPP) with a metabolic phenotype. In addition, low maternal serum DLK1 concentrations were significantly lower in pregnant women wh...

Introduction: The metabolic effects of oral hormonal contraception (OC) on telomere length (RTL) in young women with T1D are unknown.Objective: To determine the effect of using an OC on glycemic control, inflammatory profile, and RTL in young women with T1D and healthy women without diabetes (C).Methodology: T1D (n:20, age: 20.6 &pm; 3.3 years) and C (n:22, age 20.2 &pm; 3 years) u...

Aim: This study aimed to compare the levels of appetite-regulating hormones (ghrelin, leptin, peptide-YY (PYY), neuropeptide-Y (NPY)) in girls with idiopathic central precocious puberty (ICPP) before treatment with prepubertal girls, and to evaluate changes in these hormone levels and body composition during leuprolide acetate (LA) treatment.Methods: This prospective, cross-sectional study included girls with ICPP, isola...

Background: A disease of the immune system, responsible for 95% of cases of hyperthyroidism in children is very rare at this age, it affects one child in 10 million.Presentation: Khadija 3 year old girl admitted for goiter, no goitrogenic substances No drug Shot, No Inbreeding, goiter paternal aunt, The trouble was in the beginning 1 year a height and weight advance:+1 DS weight, height+3.2 DS, weakness, weight loss, Profuse sweating, tachycardia, irrita...

Aim: to assess and follow-up anthropometric and biochemical parameters in patients with abdominal obesity after a lifestyle intervention.Patients, Material and Methods: 122 children and adolescents with abdominal obesity, aged 7 to 16 years, were included in a control randomized intervention study (NCT031472). Abdominal obesity was diagnosed using the waist circumference. The intervention included an intensive phase duri...

Objective: The objective of this study was to investigate protective potential of metformin on membrane linked functions and glucose transporter in diabetic aging female rats.Background: The emerging view is that diabetic brain features many symptoms that are best described as accelerated brain aging.Methods: Young (3 months) adult (12 months) and aged (24 months) rats will be diabetic by using alloxan monohydrate. After metformin ...

Puberty is defined by the appearance of secondary sexual characteristics and the maturation of reproductive function. It is driven by an increase in sexual steroid hormone synthesis under the control of the gonadotropic axis. The key event in puberty initiation is an increase in the pulsatile release of the GnRH by hypothalamic neurons, triggering the release of LH and FSH. This pubertal increase in GnRH secretion is associated with increases in glutamatergic inputs and decrea...
