Introduction: Continuous Glucose Monitoring (CGM) devices have introduced new metrics to assess metabolic situation of patients with type 1 diabetes mellitus (T1DM). Among them, the glucose management indicator (GMI) provides a proxy to HbA1c, however, these measures do not always match.Purposes: To evaluate the concordance between GMI and HbA1c, and determinate in which scenarios GMI could replace HbA1c.Subjects a...

Introduction: Variegated mosaic aneuploidy syndrome (MVA) is a rare autosomal recessive disease characterized by a variable percentage of chromosomal gains and losses, resulting in multiple mosaic aneuploidies, which explains a great phenotypic variety and may predispose to the development of cancer. Bi-allelic mutations in CEP57 are the cause of MVA2. CEP57 encodes a centrosome protein involved in microtubule stabilization and is crucial for maintaining prope...

Objectives: Previous studies have described impaired growth in HIV-infected children. Many of them showed weight and height improve after ART initiation Most series include children from resource limited settings in which malnutrition is frequent and treatment is not fully available. We aim to characterize long-term growth in a cohort of HIV-infected children after ART initiation and to identify determinant factors.Methods</stron...

Insulin resistance and hepato-visceral (central) fat excess are thought to contribute to an earlier timing of adrenarche/pubarche and puberty/menarche; this earlier timing in turn relates often to a mismatch between pre- and postnatal weight gain, which can be estimated by calculating the Z-score change from birth weight (BW) to body mass index (BMI) in childhood. We tested the hypothesis that this calculation may serve as a proxy of insulin resistance and hepato-visceral adip...

Hypophosphatasia is a congenital disease, characterized by a defect in bone and dental mineralization, secondary to a deficiency in the biosynthesis of the non-specific tissue isoenzyme of bone, liver and kidney alkaline phosphatase (TNSALP). Clinical phenotype varies with age and its clinical expression is sometimes very latent. There is a small but significant number of pediatric patients NOT diagnosed with hypophosphatasia. The values of low phosphatases may go unnoticed in...

Background: The TRH receptor (TRHR) is a G-protein coupled receptor activated by hypothalamic TRH. In thyrotropes, TRH-TRHR signalling controls synthesis, secretion and bioactivity of TSH. Human TRHR defects are extremely rare, and only three cases are known with central hypothyroidism and short stature as variable presenting feature.Objective and hypotheses: Phenotypical characterization of a family with suspected central hypothyroidism and inv...

Background: The aim of therapy in patients with congenital adrenal hyperplasia (CAH) is to use glucocorticoid doses as low as possible to achieve adrenal suppression. Both chronically increased androgen secretion and increased glucocorticoid exposure may adversely affect adult height and in some patients this therapeutic balance is difficult to achieve. In these particular cases aromatase inhibitors (AI) could be indicated with de aim to reduce glucocorticoid doses avoiding th...

Background: T1DM incidence in children varies across regions and countries, showing a continue rise Worldwide.Objective and hypotheses: To determine the incidence of T1D in Chilean children under 20 years between 2006 and 2012.Method: We reviewed mandatory notifications of T1D (GES Program) in Chile’s public health system in population younger than 20 years between 2006 and 2014. Data were obtained from the Department of Infor...

Background: Hyperinsulinemic hypoglycemia (HH) is the most common cause of severe, persistent neonatal hypoglycemia. Treatment of diffuse forms that is unresponsive to diazoxide and octreotide is near total pancreatectomy.Objective: To describe the clinical characterization of a newborn with congenital HH due to a diffuse pancreas lesion and unresponsive to diaxoside.Case report: Preterm term male of 33 weeks born to non-consanguin...

Background: Kenny-Caffey syndrome type 1 is a rare autosomal recessive syndrome caused by mutation in the TBCE gene (Tubulin specific chaperone E) located in the chromosome region 1q42-q43. Less than 60 cases have been reported in the literature especially in the Middle East and Arabic countries. This syndrome is characterized by growth retardation, dysmorphic features, with thickened bone cortex and medullary stenosis, hypoparathyroidism, teeth anomalies. Hypopituitarism with...
