Introduction: Non-classical congenital adrenal hyperplasia is the most common pathological cause of early pubarche in prepubertal patients. However, this may also be the first manifestation of central precocious puberty or an androgen producing suprarrenal or ovarian tumor.Objective: To present a clinical case initially misdiagnosed as Congenital Adrenal Hyperplasia that turned out to be an Ovarian Tumor of Leydig Cells.Clinical ca...

Background: Until now, altered balance of Th1 and Th2 immune cells has been postulated to play an important role in the pathogenesis of autoimmune thyroid diseases (AITD). However, recent studies on thyroid diseases have suggested a new role for Th17 cells that have been classified as a new lineage, distinct from Th1, Th2 and Treg cells. Despite wide interest, the role of Th17 cells in the pathogenesis of inflammatory and autoimmune diseases is still debated.<p class="abst...

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with increase androgen levels and PCOS have arisen.Objective: To determine whether PA in children at pubertal onset (TII) determines a different timing of pubertal events and a different pattern of ovarian and adrenal hormones.Methods: A total of 583 girls from the longitudinal cohort (Growth and Obesity Cohort Study, born 2002) wer...

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with an increased metabolic risk have arisen. This risk may depend on ethnic background and infancy weight gain, which could be different by gender.Objective and hypotheses: To determine whether PA in children at pubertal onset (TII) determines a higher metabolic profile.Methods: 1190 children (49.9% female) from the longitudinal co...

Background: Autoimmune thyroid disease (AITD) is the most common organ-specific autoimmune disorder. Genetic background, environmental and endogenous factors are play important roles in determining the activation of immune cells or the efficacy of the immunoregulatory pathways. Recently emphasizes the immunosuppressive role of B regulatory cells (phenotype CD19+CD24hiCD27+IL-10+, CD19+IL-10+) in regulation of immune respon...

Introduction: Hematopoetic progenitor stem cells (HSCs, CD133+/CD45+) and very small embryonic-like stem cells (VSELs, CD133+/CD45−) can differentiate into specific immune cells. Some studies suggest that levels of HSCs and VSELs change during therapy with growth hormone (GH) or insulin-like growth factor 1 (IGF-1). GH deficiency (GHD), an endocrine disease connected with insufficient production of GH by pituitary gland, is tre...

Background: Life expectancy of children with human immunodeficiency virus (HIV) has increased due to highly active antiretroviral therapy. Metabolic disorders and changes in bone mineral density (BMD) are common in adult patients with HIV. There are few studies evaluating metabolic and bone involvement in children.Objective and hypotheses: To evaluate metabolic disorders and BMD in vertically HIV-infected children in four Chilean hospitals.<p class="...

Background: Severe obesity among adolescents is increasing worldwide. Bariatric surgery is a controversial subject in this group of age, surgical timing is even more controversial. Patterns of surgical weight loss could be different between patients with greater excess weight, perhaps with less promising results.Objective and hypotheses: To compare anthropometric outcomes among adolescents with BMI 35–40 and over 40, underwent laparoscopic sleeve ga...

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...

Introduction: The metabolic effects of oral hormonal contraception (OC) on telomere length (RTL) in young women with T1D are unknown.Objective: To determine the effect of using an OC on glycemic control, inflammatory profile, and RTL in young women with T1D and healthy women without diabetes (C).Methodology: T1D (n:20, age: 20.6 &pm; 3.3 years) and C (n:22, age 20.2 &pm; 3 years) u...
