Background: Neuroendocrine tumors from adrenal and extra-adrenal chromaffin cells are characterized by overproduction of catecholamines (CA), leading to the increase of urinary O-methylated metabolites (uO-Met) excretion, reliable biomarkers for the initial screening, diagnosis and monitoring of patients with pheochromocytoma and paragangliomas (PPGLs).Objective: To develop and validate a UHPLC-MS/MS method for the simul...

Background: The degree of suppression of the pituitary-ovarian axis in girls with central precocious puberty (CPP) under GnRH analogue (GnRHa) treatment is usually assessed at pituitary levels. However, the extent of ovarian function suppression under GnRHa treatment has not been evaluated.Objective: To evaluate ovarian activity in CPP girls before and during treatment with GnRHa.Patients and methods: In this prospective study, 11 ...

Short children who are not GH deficient, often necessitate a different strategy, especially those with acceleration of bone age, which greatly limits height poten¬tial and the time available for growth. In this setting the use of agents to delay bone maturation has been explored to improve adult height. Estrogen principally modulates epiphyseal fusion in females and males through ERα. Aromatase inhibitors (AIs) block androgen to estrogen conversion, slowing down grow...

Introduction: Management of pediatric patients with short stature and poor adult height prognosis it’s challenging and effectiveness of treatment with growth-promoting agents is controversial when linear growth is ending. Aromatase inhibitors (AI) have become a therapeutic option as they promote slowdown of bone maturation and increase final height, but yet is a non-approved indication.Aim: To conduct a survey abou...

Background: Premature adrenarche (PA) has been associated to increased metabolic risk. Areas of controversy regarding associated co-morbidities are precocious pubarche, PCOS and lower birth weight, which may depend on ethnic background.Objective and hypotheses: To describe the risk of precocious thelarche (PT, <8 years), pubarche (PP, <8 years F, <9 years M) and gonadarche (PG, <9 years) in children with premature adrenarche.<p class=...

GHD is the most common endocrine disorder in children with short stature (~1 in 4000). Appropriate diagnosis should synthesize auxological, biochemical and neuroradiological data. However, until now there are significant controversies, especially from the laboratory interpretation. A false positive diagnosis can lead to a significant wasted expenditure and unnecessary exposure to rare potential adverse effects. Given these open issues about biochemical diagnosis of GHD in chil...

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...
