The coronavirus disease (COVID-19) pandemic brought with it a state of alarm as of March 14, 2020, which implied a restriction on the mobility of the general population and home confinement. One of the main concerns raised by isolation was the substantial reduction in energy expenditure due to children spending more time sitting or participating in activities that involve very low rates of energy expenditure, such as watching television, managing the different networks social ...

Background: Neurofibromatosis type 1 (NF1) caused by loss of function mutation in the NF1 gene; leads to the hyperactivation of RAS and its downstream mediators and contributes to tumour formation. The main manifestations of NF1 are café au lait macule, axillary and/or inguinal freckling. Neurofibroma plexiform is specific for NF1 and identified on the face and trunk. Urogenital presentation is infrequent in the penis. Identification of this lesion is essential because it...

Background: Insulin/IGF1 signaling plays a critical role in central glucose bioavailability and lipid metabolism. An increase in glucose disposal can generate reducing agents through the pentose-phosphate pathway necessary for the synthesis of free fatty acids (FFA). Disturbances in lipid synthesis are related to the appearance of insulin resistance and diabetes. The insulin receptor substrate 2 (IRS2) deficient mice (IRS2−/−) is an excellent model to st...

Background: The GH/IGF1 axis has important roles in growth, metabolism, lipid profile and body composition. GH receptor disrupted mice (GHRKO mice) are resistant to the action of GH, thereby, GHRKO mice are dwarf, hypoinsulinemic, hypoglycemic and obese. Consumption of a high fat diet (HFD) induces inflammatory processes in a multitude of peripheral tissues, including hypothalamus.Objective and hypotheses: Our aim was to evaluate the effect of HFD intake...

Background: Prevalence of obesity and its complications including type 2 diabetes mellitus, impaired glucose tolerance and insulin resistance have been increased among children and adolescents during recent decades.Objective and hypotheses: The aim of this study was to determine the prevalence of impaired glucose tolerance and insulin resistance among overweight or obese children and adolescents.Method: This cross sectional study w...

Background: Most organs including bone are affected in type 2 Diabetes (T1D) mechanisms. The exact mechanism of bone derangement is still unknown.Aim of work: i) Assessment of Pyridinoline crosslinks as a bone resorption marker and alkaline phosphatase as a bone formation marker in T1D in children & adolescents. ii) To determine the effect of glycemic control and disease duration on bone turnover.Subjects and methods: 39 T1D pa...

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare disorder caused by loss-of-function mutations in the gene encoding the forkhead box P3 (FOXP3) transcription factor. This factor plays a key role in the differentiation and function of CD4+ CD25+ regulatory T cells, essential for the establishment and maintenance of natural tolerance.Objective: To describe clinic...

Background: Chronic kidney disease (CKD) was defined by structural or functional renal abnormalities, or an estimated glomerular filtration rate (GFR) of less than 60 mL/min per 1.73 m2. A child with CKD may develop many complications such as: anemia, poor growth and nutrition, bone and mineral disorders, cardiovascular complications, and complications of hemodialysis, and peritoneal dialysis.Aim: Assessment of severity ...

Aim: To determine the sensitivity, specificity of basal LH measurement compared to the GnRH test in patients with Central precocious puberty (CPP) and determine the cut off point for basal LH to diagnose CPP.Methods: 680 female patients were referred for presumptive diagnosis of central precocious puberty in the city of Bogota. All patients went through a GnRH test, using a Roche immunoassay for Luteinizing hormone (LH) and follicle stimulating hormone (...

Background: The deterioration caused DMtipo1 anthropometric and pubertal development. With intensive treatment, improved HbA1c and less microvascular complications should be similar to normal population.Objective: To study the pubertal development in our population with DM1 and final somatometric variables reached in relation to the normal population.Material and methods: Retrospective study of DM1A debut from diagnosis to final he...
