Introduction: Identifying the nutritional diagnosis of adolescents is crucial for developing public health strategies that promote the adequate development of this population.Objective: To analyze the temporal trends of the BMI of Brazilian adolescents (10 to 19 years old) between 2010 and 2021.Methods: Descriptive ecological study. Data obtained from e-SUS Primary Care. The preval...

Introduction: Differentiation between constitutional delay of growth and puberty (CDGP) and congenital hypogonadotropic hypogonadism (CHH) during early adolescence is challenging, as patients exhibit a similar clinical picture and there are no definite clinical or biochemical markers that distinguish these 2 pathologies. A delay in diagnosis, especially for CHH, may have short and long-term health consequences. The aims of this study were: 1) To evaluate the u...

Background and Objectives: Chronic administration of synthetic glucocorticoids affects 1% of the world population and is responsible for secondary adrenal insufficiency for 40% of the patients. In pediatrics, glucocorticoid-induced adrenal insufficiency (GI-AI) diagnosis is based on the Low Dose Synacthen Test (LD-SST). Screening for glucocorticoid-induced adrenal insufficiency implies medical and economical costs due to the necessity of an intravenous line an...

Purpose: Isolated growth hormone deficiency (IGHD) is a rare condition mainly caused by mutations in GH1. The aim of this study was to assess the contribution of GHRHR mutations to IGHD in a very large cohort of patients.Methods: All GHRHR coding exons and flanking intronic regions were sequenced in 312 unrelated patients with non-syndromic IGHD. Functional consequences of all newly identified missense variants were assessed <e...

Background: For young adults with type 1 diabetes, transition from a paediatric setting to an adult care setting is a vulnerable period with risks for gaps in care. These emerging adults need to develop skills for managing their diabetes yet it is often challenging to cover all anticipatory guidance topics related to type 1 diabetes. In the context of a structured transition clinic, we hypothesized that by leveraging teens’ facility with technology and marketing/design we...

Introduction: Monogenic defects in the leptin-melanocortin pathway result in hyperphagia and severe, early-onset obesity. Knowledge of the natural history of anthropometric parameters in patients with monogenic obesity is essential for diagnosis. However, reliable data on early childhood weight and height development in affected patients are lacking. This study aimed to evaluate the history of height, weight, and BMI development in early childhood in a Europea...

Background: GL1I2 encodes a zinc-finger transcription factor expressed in the developing hypothalamus and in Rathke's pouch, the embryonic precursor of the pituitary gland. Pathogenic GL1I2 variants have been implicated in the etiology of the broad clinical spectrum of congenital hypopituitarism (CHY): holoprosencephaly, midline facial abnormalities, Culler-Jones syndrome, combined pituitary hormone-deficiency (CPHD) and isolated GH-defi...

Background: A total of 456 skeletal dysplasias have been classified by molecular, biochemical and/or radiological criteria, into 40 groups. Despite this, the precise, final diagnosis is often difficult due to the high phenotypic and genotypic variability.Objective: To improve the molecular and clinical diagnosis of skeletal dysplasias using a custom-designed next-generation sequencing (NGS) panel.Method: A total of 56 skeletal dysp...

Background: ACH, the most common short-limbed skeletal dysplasia, is characterized by defective endochondral ossification resulting from gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3) gene, a negative regulator of endochondral bone formation. Current treatment options are non-targeted, ineffective, or painful interventions aimed at preventing or treating complications. Infigratinib is an orally bioavailable and selective...

Background: ACH is the most common short-limbed skeletal dysplasia, affecting between 1 in 15,000 to 1 in 30,000 live births. Children and adults with ACH have disproportionate short stature, with a final height of approx. 131 cm for males and 124 cm for females. People with ACH are prone to significant co-morbidities, including obstructive sleep apnea, chronic otitis media with conductive hearing loss, spinal stenosis, and a propensity towards obesity. In som...
