Sox2+ve cells in the adult murine pituitary are stem cells with tumour-inducing potential

Martinez-Barbera Juan Pedro , Andoniadou Cynthia

Background: Several lines of evidence suggest that the adult pituitary contains a population of tissue-specific stem cells capable of differentiating into hormone-producing cells. Previously, we have shown that Sox2+ve cells are able to self-renew and differentiate in vitro, suggesting that this population of undifferentiated cells may contain stem cells in vivo. When targeted with oncogenic mutations adult stem cells can become cancer stem cells, able to self-renew and give r...

Changes in BMI in GHD and SGA Children in the First Year of Treatment

Llano Juan-Pablo , Picon Teresa Ortiz , Llano Mauricio

Background: The effect of GH has been classically described as anabolic which should lead to changes in body composition in children during treatment. Likewise, GHD typically occurs in children with short stature and increased BMI.Objective and hypotheses: The aim of this study was to assess changes in BMI in children before and after initiation of treatment with GH in patients with GH deficit in small for gestational age and year. Starting variables as ...

Small Stature: A Singular Difference for Accessing to Job

Diez-Lopez Ignacio , Sarasua Ainhoa , Lorente Isabel , Carranza Manuel

The pathological low stature is considered to be one that does not conform to normality (<2 SDS), that with a pathological growth rate. An obvious element is the conditioning that can generate in their professional outings, both in public and private activity. This seems to be evident in the female sex than in the male sex. The health system considers the treatment (with Ghrh) in pathological size without considering sexual dimorphism.Goals: To study...

Effects of Growth Hormone Treatment on Immunity

Canete Ramon , Caballero Maria Dolores , Aguado Rocio , Santamaria Manuel

Background: As well as acting on longitudinal growth, growth hormone (GH) also has a number of metabolic effects, and is involved in the regulation, functioning and development of the immune system.Aims: To evaluate the immune profile in GH-deficient children after 6 months’ GH treatment.Method: A total of 44 children were examined before and after a six-month course of treatment with rhGH (0.03 mg/Kg per day). Levels of IGF1 ...

Relevance of Astrocytic Signals for GnRH-Neuronal Function

Ernst Johanna , Moeller Hanna , Pfeifer Manuel , Heger Sabine

Background: Gonadotropin releasing hormone (GnRH)-secretion is not only regulated by neuronal factors but also by astroglia cells via growth factors (transforming growth factor α (TGFα), neuregulin (NRG)), prostaglandin E2 (PGE2) and the erbB receptor family. Mutations of TGFα and erbB1 result in an impaired reproductive capacity. Mice show a characteristically skin phenotype with wavy hair and curly whiskers. The rat strain SPRD-Cu3 (curly) shows a sim...

Comparison of Manual and Automated Bone Age Assessment in 1285 Children and Adolescents Aged 5 to 16 Years

Maratova Klara , Zemkova Daniela , Lebl Jan , Soucek Ondrej , Pruhova Stepanka , Kolouskova Stanislava , Snajderova Marta , Krasnicanova Hana , Sumnik Zdenek

Background: Skeletal maturation is the most reliable indicator of biological age in children and adolescents. The evaluation of hand and wrist X-Ray according to Tanner-Whitehouse (TW3) or Greulich-Pyle (GP) are the most commonly used methods for biological age assessment. Automated bone age assessment has recently become increasingly popular, however a large independent study comparing automated and manual evaluation of bone age is still missing. The aim of this study was to ...

Association of the Sizes and Composition of HDL with Hepatic Steatosis in Adolescents with Type 2 Diabetes (T2D)

Antonio Orozco Morales Jose , Torres Tamayo Margarita , Medina Urrutia Aida , Gabriel Juarez Rojas Juan , Reyes Barrera Juan , Jorge Galarza Esteban , Dies Suarez Pilar , Medina Bravo Patricia

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The association between T2D and non-alcoholic fatty liver disease (NAFLD) has been described; this increases the risk of coronary heart disease (CHD). Recent evidence suggests that sizes and composition of HDL may be more important that HDL-C levels in predicting CHD. There is not data regarding the HDL subclasses distribution and composition in T2D youths with hepatic steatosis (HE).<p c...

Why understanding hemoglobin glycated measurement can be important: Santa Juana hemoglobin variant and falsely elevated HbA1c

Lorand Juan , Boutsen Laure , Gueulette Emmanuelle , Maisin Diane , Closset Mélanie , Mouraux Thierry , Beckers Dominique

Diabetes mellitus is a chronic disease. The risk of microvascular complications is correlated with hemoglobin A1c (HbA1c) level [1] Educating the diabetic patient to keep an HbA1c below 7% reduce the risk of long-term complications. We report the case of a 15 years old teenager, with chronical headache, referred for diabetes mellitus with a fasting glycemia of 83 mg/dl (normal < 100) and an HbA1C of 8.3% using an Ion-exchange High Performance Liquid Chromatography (HPLC, Ad...

Incidence and Severity of Type 1 Diabetes Mellitus during COVID-19 Pandemic

Dieguez Abigayil , DeLacey Sean , Lado Juan , Levin Laura , Ranganna Adesh , Wu Margaret , E. Bianco Monica

Background: The COVID-19 pandemic continues to impact healthcare overall particularly in relation to diabetes. Initial studies showed delays in emergent healthcare utilization, decreased preventative care visits, and more severe presentations of new onset diabetes. However, the pathophysiologic relationship between COVID-19 and type 1 diabetes is not yet well understood.Objectives: Our primary objective was to compare th...

Objective: To understand the clinical characteristics, etiological distribution and related metabolic problems of children with premature pubarche.Methods: The clinical data of 55 cases of premature pubarche were summarized. All the children were tested by ACTH stimulation test and GnRHa stimulation test, of which 17 cases were detected by CYP21A2 gene,and 16 cases of Premature Adrenarche (PA) and 14 cases of Isolated Pr...
