Background: Premature adrenarche (PA),characterized by high concentrations of DHEAS,has been considered a benign condition until recently,where associations to increased metabolic risk and PCOS have arisen,which may depend on ethnic background and infancy weight gain.Objective and hypotheses: To determine whether PA in girls determines:i)a different timing of pubertal events, and ii)a different pattern of Ovarian morphology/hormones and adrenal hormones....

Introduction: During last years there is an increasing number of referrals because of gender incongruence worldwide. In Argentina, in 2012, a gender identity law was sanctioned, stablishing the right of gender reassignment during childhood, adolescence, youth and adulthood, without the need of previous medical and/or mental health evaluation. This was followed by a great number of referrals. There is scarce literature regarding longterm outcome in transgender persons who start...

Background: Children with congenital heart disease (CHD) are predisposed to growth failure, due to the decreased intake of nutrients and also due to the increased energy requirements. Growth failure represents a frequent cause of increase of both morbidity and mortality in children with CHD.Objective and hypotheses: Assessment of physical development in children with CHD and identification of significant factors that influence z scores.<p class="abst...

Background: Congenital hypothyroidism (CH) is a treatable thyroid hormone deficiency that causes intellectual disabilities and growth deficiency if not detected and treated early.Material and Methods: We retrospectively analyzed the medical records of 22 patients, 13 (59%) females and 9 (41%) males, with positive CH screening at birth and confirmed by TSH & FT4 serum concentrations measurements, thyroid ultrasound an...

Introduction: X-linked hypophosphatemia (XLH), due to PHEX mutation, is the most common genetic form of rickets in children. This rare disease is characterized by decreased tubular reabsorption and increased renal loss of phosphorus due to increased FGF-23 levels. In children, XLH is often manifested by short stature, rickets and bowel limbs deformity. Conventional treatment with oral phosphorus salts and calcitriol is not always well tolerated which has a pro...

Background: FGF21 is a metabolic and growth regulator.Aim: To investigate the role of FGF21 during growth in infancy.Methods: Cohort of 40 term (T) and 40 preterm (PT) newborns whose length and weight were evaluated prospectively at birth, 6 months, and 12 months. Blood samples for FGF21, IGF1, leptin, insulin and glucose were collected at 6 and 12 months. In addition, FGF21, I GF-I, leptin, and insulin were measured in cord blood ...

Background: Extra Uterine Growth Restriction (EUGR) represents a serious comorbidity in infants born very low birth weight (VLBW). In fact, failure in postnatal growth and malnutrition at vulnerable ages can interfere with growth recovery and neurodevelopment at older ages.Hypothesis: Aim of the study was to assess whether and how the postnatal early growth patterns of VLBW may affect later growth, spontaneous motility a...

Introduction: Childhood obesity is associated with several complications, involving many systems. The prevalence of respiratory problems, such as obstructive sleep apnea syndrome (OSAS), is higher in obese children and adolescents. In fact, OSAS affects 13–59% of obese children and the severity is strongly associated with weight excess. Although overnight pulse oximetry (PO) can be used for diagnosing OSAS, a complete night polysomnography (PSG), which re...

Introduction: In children with classical congenital adrenal hyperplasia(CCAH) linear growth allows monitoring metabolic control. Precocious puberty could compromise their growth. There are few studies in patients with CCAH diagnosed by neonatal screening(NS) about this subject.Aims: To analyze linear growth and precocious puberty in children with CCAH detected by NS.Method: Thirty-...

Context: Transient thelarche (TT) corresponds to the appearance, regression and subsequent reappearance of the breast bud in girls. Only a single study about its frequency and progression is available (Lindhardt Johansen JCEM 2017).Objective and Hypotheses: To determine whether girls with TT girls (group 1) compared to girls without TT (group 2) show differences in i) timing/sequence of pubertal events ii) pattern of rep...
