Background: Magnetic resonance imaging (MRI) of the hypothalamic-pituitary area is extremely useful in the investigation of patients with central diabetes insipidus (CDI) due to infiltrative processes.Objective: We aimed to associate pituitary stalk thickness with the etiology of CDI and hormone deficiencies.Method: A retrospective single-center study of 15 patients (four boys and 11 girls) with CDI was performed and clinical-epide...

Background and Aims: Central Precocious Puberty (CPP) caused by the early activation of the hypothalamic-pituitary-gonadal axis is a rare affection that occurs in 0.2% in girls. Clinical signs are suggestive and LHRH-test could be sometimes difficult to use and not always contributive. Gonadotropin assay in twenty-four hours-urinary collection could be an interesting option. The present work intended to evaluate the diagnostic interest of 24-hour urinary gonad...

Body Mass Index (BMI) has a high association with body fat percentage and direct association with a higher degree of comorbidities. Categorizing patients only by the degree of obesity, as has been done over time, restricts the possibility of detecting and giving timely treatment to other aspects. The Edmonton Obesity Staging System for Pediatrics (EOSS-P) has been proposed as a tool to categorize obesity not only by BMI, but also by assessing metabolic complications, functiona...

J. Chueca Maria , Gabari Mercedes , Burillo Elisabeth , Berrade Sara , Herrero Sara , Francisco Laura , Lopez de Dicastillo Ana , Andres Carlos

A structured program of therapeutic education is essential to achieve a good result from the use of technology in the treatment of diabetes.Objectives: Facilitate knowledge, skills and aptitudes to patients and their families in therapy. Promote the capacity for self-management and adherence to treatment. Provide ongoing support to patients. Improve clinical outcomes, health status and quality of life.Metho...

The Usefulness of Combined Analysis of Serum and Salivary Maximum Cortisol Response to Low-Dose ACTH Test to Define the Requirement of Hormone Replacement Treatment

Vaiani Elisa , Lazzati Juan Manuel , Maceiras Mercedes , Gil Silvia , Costanzo Mariana , Zaidman Veronica , Dratler Gustavo , Belgorosky Alicia

Introduction: The low-dose synacthen test (LDT) is widely used to assess central adrenal insufficiency (CAI); however, the total serum cortisol (C) cut-off value is controversial. A correct diagnosis of CAI is required, but overdiagnosis may lead to unnecessary hormone replacement therapy. Salivary cortisol (SC) reflects the levels of free serum cortisol and is a noninvasive alternative.Objective: To define a new cut-off value of serum cortisol in pediat...

45,X/46,XY Chromosomal Disorders of Sex Development: Experience from a Cohort of 50 Patients Followed in One Single Institution

Costanzo Mariana , Guercio Gabriela , Geniuk Nadia , Berensztein Esperanza , Manuel Lazzati Juan , Maceiras Mercedes , Zaidman Veronica , Aurelio Rivarola Marco , Belgorosky Alicia

Background: Disorders of sex development (DSD) are those congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. 45,X/46,XY mosaicism results in a large clinical spectrum of DSD including from female patients with Turner’s syndrome to normal appearing males.Objective and hypotheses: The main aim of this study is to review the clinical and gonad histological findings in a cohort of chromosomal DSD patients f...

Characterization of IGFI Receptor Expression and Localization in Paediatric Gliomas Upon Diagnosis According to WHO 2007 Grading

Clement Florencia , Venara Marcela , Maglio Silvana , Martin Ayelen , Matho Cecilia , Petre Cesar , Lombardi Mercedes Garcia , Bergada Ignacio , Pennisi Patricia

Background: Gliomas are the most common subgroup of CNS tumours in children. Histologic grading is a means of predicting the biological behavior of these tumours and survival is strongly correlated with tumour gradation. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. Recently, nuclear translocation of the type 1 IGF1R has been demonstrated in tumour tissues. Although the IGF1R expression has been described in C...

Pseudo-Precocious Puberty in Androgen Insensitivity Syndrome Secondary to a Prepubertal Oestrogen Producing Sertoli Cell Tumour

Warman Diana Monica , Berensztein Esperanza , Marino Roxana , Ramirez Pablo , Costanzo Mariana , Maceiras Mercedes , Rivarola Marco A , Belgorosky Alicia

Background: Androgen insensitivity syndrome (AIS) is an X-linked hereditary disease with AR gene loss-of-function mutations in 46,XY patients. They undergoes poor development of secondary sex characteristics, except for breast development at puberty. AIS patients are prone to develop germ cell cancer, even though with lower incidence than in dysgenetic gonads secondary to defects in organogenesis.Case presentation: We described a 3-years-old gir...

Inhibition of IGF1R by IGF1R/IR Inhibitor OSI906 as a Targeted Therapy for Glioblastoma: in vitro & in vivo Studies

Fernandez Maria Celia , Martin Ayelen , Clément Florencia , Venara Marcela , Fernanda Castro Julia , Lombardi Mercedes Garcia , Bergadá Ignacio , Pennisi Patricia

Background: CNS tumours are the most frequent solid tumours in children. In pediatric gliomas, IGF1R nuclear localization was significantly associated with both high grade tumours and increased risk of death and contributed to the aggressive phenotype of glioblastoma by increasing motility and metabolism of tumour cells rather than increasing its proliferation. For children chemotherapy after surgical resection is the mainstay of therapy. However, the best reg...

Plasma Tocopherols and Carotenes are Decreased in Spanish Children and Adolescents with Insulin Resistance, Independently of Obesity

Rupérez Azahara I. , Lozano Gloria Bueno , Leis Rosaura , Gil-Campos Mercedes , Gil Ángel , Moreno Luis A. , Mesa María D. , Aguilera Concepción M.

Introduction: Childhood obesity and insulin resistance (IR) are rising in prevalence, increasing the future adults' cardio-metabolic risk. One of the potential mechanisms behind these alterations is oxidative stress, fruit of increased free radical production and diminished antioxidant defense. Although low plasma vitamin concentrations and oxidative stress have been observed to be associated with obesity in adults and children, their association with IR i...
