Introduction: Since the beginning of the coronavirus pandemic, an increase in cases of new-onset type 1 diabetes (T1D) in children and adolescents has been observed in many countries, including Brazil.Objectives and Methods: In this descriptive study, we aimed to investigate the frequency of new-onset T1DM and the frequency and severity of diabetic ketoacidosis (DKA) in a referral Brazilian University Hospital, 38 months...

Introduction: Telemedicine, or the use of CIT (Communication and Information Technology) to deliver and/or share medical remote assistance and knowledge, is of paramount importance, mainly in large countries, with social and economic disparities, as Brazil, by means of teleconferences, webconferences, webcasts and use of a wide range of interactive technologies, helping activities of assistance and professional health education. One of the activities provided by our RUTE (Univ...

Background: Body weight has a close correlation with bone mass in humans and high fracture rates has been reported in both obese and underweighted individuals. It is not clear the role of bone marrow adiposity (BMA) and the IGF system in this process.Aim: The aim of this study was to analyze bone composition and BMA in obese and non-obese children/adolescents and correlate them with the expression of the IGF type-1 receptor (IGF1R) in peripheral lymphocy...

Background: Obese children are often taller than non-obese ones before puberty. Reports on the GH/IGF system in obese children are not consistent and do not explain the increased height observed. Changes in IGF1 bioavailability/bioactivity have been claimed as a possible explanation, however, no data is available regarding the expression of the IGF type 1 receptor (IGF1R) gene.Objective and hypotheses: To study the expression of IGF1R gene in obese child...

Background: Subclinical hypothyroidism (SH) is defined as normal tyrosine levels in the presence of TSH concentrations between 5 and 10 mU/ml. The impact of SH on IGF system and growth of infants remains unknown.Objective and hypotheses: To evaluate IGF1, IGFBP3 levels and growth velocity (GV) of infants with SH.Method: 98 children up to 36 months of age, recalled due to a TSH >5 mU/ml in the neonatal screening test, were divid...

Background: Congenital hyperinsulinism (CH) is the most common cause of persistent hypoglycemia in neonatal period. The inadequate secretion of insulin leads to high morbidity and mortality in those newborns. Despite the recent progress in the diagnosis and management of CH, until recently, the situation in Brazil has been that of early 1990’s. The epidemiology is unknown and state-of-the art management has not been available.Objective and hypothese...

Background: Growth spurt is a major event in central precocious puberty (CPP). GnRH analogue (GnRHa) therapy inhibits gonadal axis and decreases height velocity. However, serum IGF1 and IGFBP-3 remain high as before therapy. Reports on IGF type 1 receptor (IGF1R) in CPP are yet unavailable.Aim: To study IGF1R mRNA expression in girls with CPP before and during GnRHa therapy.Methods: 34 girls with CPP were studied. Sixteen of them (...

Feeding behavior is exquisitely regulated by homeostatic and hedonic neural substrates that integrate energy demand as well as the reinforcing and rewarding aspects of food. Understanding the net contribution of homeostatic and reward-driven feeding has become critical due to the ubiquitous source of energy-dense foods and the consequent obesity epidemic. Hypothalamic, agouti-related protein-secreting neurons (AgRP neurons) represent primary orexigenic drives of homeostatic fe...

Keywords: Retrospective descriptive study, diabetes mellitus type 1, diabetic ketoacidosis, NDS-UMC, Byblos, Lebanon, single-center experience.Background: Type 1 diabetes mellitus (T1DM) increases worldwide especially in the Mediterranean region. Epidemiological studies about T1DM are made in many countries, but Lebanon lacks such data.Objective: This is a descriptive study of demo...

Background: While the relationship between subclinical hypothyroidism and major depressive disorder (MDD) has been studied in adults in cross-sectional and prospective population-based studies, this has not yet been done in adolescents. However, since thyroid function and MDD risk are subjected to maturational processes and ramifications of illness duration over the life span, these findings may not readily transfer to adolescents.<stron...
