Background: Severe obesity (SO), defined as BMI ≥95th percentile, has increased worldwide among adolescents. American studies estimated that 1.3–2.8% of 12–19-year-old individuals have a BMI >40 kg/m2 or a BMI >35 kg/m2 with at least one serious co-morbidity. The immediate and long-term risks associated with SO in adolescents include cardiovascular and metabolic diseases, obstructive sleep apnoea, and nonalcoholic fatty liver disea...

Background: Laparoscopic sleeve gastrectomy (LSG) has been established as a safe and effective bariatric procedure during adolescence, but its long-term results remain uncertain. Our aim was to report and compare the short- and long-term outcomes of LSG in adolescents.Methods: We performed a retrospective analysis of patients submitted to LSG between 2010 and 2013 in our Institution. Baseline, short-term (1 year) and lon...

Background: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease which occurs in the setting of insulin resistance and increased adiposity. It has rapidly evolved into the most common liver disease seen in the pediatric population. NAFLD can be divided into non-alcoholic fatty liver (NAFL), which denotes bland steatosis, and non-alcoholic steatohepatitis (NASH), which is marked by steatosis and lobular inflammation and hepatoce...

Introduction: Primary Pseudotumor cerebri (PPTC), also known as idiopathic intracranial hypertension, is clinically characterized by increased intracranial pressure in an alert and oriented patient, with no evidence of deformity or obstruction of the ventricular system on neuroimaging. Cerebrospinal fluid analysis is normal except for increased intracranial pressure at lumbar puncture, greater than the 90th percentile (28 cm of H2O) in the pediatric population. Papilledema may...

The growth hormone (GH)-insulin-like growth factor (IGF-1) system is essential for optimal human growth and energy homeostasis. Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease involved in the liberation of free IGF-1, leads to problems in growth and bone density in humans and mice. Patients with PAPP-A2 deficiency also present lower body mass and mild glucose intolerance. The present study aimed to determine the influence of 1 month of high carbohydr...

Introduction: BIPSS before and after desmopressin stimulation has been shown to be a useful tool for diagnosis of ACTH-dependent CD and negative magnetic resonance imaging (MRI)or positive MRI but inconsistent biochemical data, in adult patients. However, little is known about its usefulness in pediatric population.Objective: To evaluate the prevalence of negative MRI, the sensitivity of BIPSS before and after desmopress...

Background: Reports suggest that youths with short stature (SS) exhibit academic under-achievement relative to cognitive aptitude and GH treatment diminishes the difference. However, interpretation of this achievement-aptitude discrepancy is confounded by the use of achievement and intelligence tests normed in different samples.Objective and hypotheses: To assess whether reports of academic underachievement in SS samples are partially attributable to cho...

Background: The correlation between obesity and depression is well established. Tryptophan (Trp) is an essential amino acid that acts as substrate for serotonin and melatonin biosynthesis, both know to play a role in satiety, anxiety, and depression. Furthermore, low plasma Trp levels have been associated with obesity.Objective: To investigate the effects of Trp supplementation as a conjunctive therapy to conventional life-style intervention on weight lo...

Background: The GH-IGF system plays an important role in strength gain. Some studies suggest that Zinc, Magnesium and Pyridoxine (ZMA) supplementation could increase GH/IGF and testosterone levels in young subjects. This hypothetical increase could lead to significant changes in body composition. ZMA is a very popular supplement, easily found in specialty stores, and it is presumed to increase GH, IGF-I and testosterone levels. However, studies are divergent regarding its effi...

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...
