Adipocytokines Delay Pubertal Maturation of Human Sertoli Cells

Wagner Isabel V. , Yango Pamela , Svechnikov Konstantin , Tran Nan D. , Soder Olle

Background: Obesity and metabolic syndrome related co-morbidities are increasingly recognized in children. Reproduction is an important target of obesity complications, including adverse effects on spermatogenesis and steroidogenesis in males. Adipocytokines are key players in various complications of obesity.Objective and hypotheses: The aim was to study the potential effects of adipocytokines on Sertoli cell function and possibly link the findings to t...

Adipose Tissue – A Source of Hyperandrogenism in Obese Females?

Wagner Isabel V. , Sahlin Lena , Savchuk Iuliia , Svechnikov Konstantin , Soder Olle

Background: Obesity in females is often associated with metabolic complications and hyperandrogenism. However, the source of androgens is not entirely clear.Objectives and hypotheses: Our objective was to find out if adipose tissue (AT) is a site of steroid production during childhood and adolescence, and if this source could add to hyperandrogenism in obese females.Methods: Parametrial and inguinal adipose tissue was collected and...

Differences in Pubertal Development and Anthropometry Between Normal Population and Type 1 Diabetic Child at Debut in Spain

Diez-Lopez Ignacio , Sarasua-Miranda Ainhoa , Sanchez-Antonio Sonia , Lorente-Blazquez Isabel

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...

Optimizing Treatment in Congenital Hypothyroidism

Serra-Caetano Joana , Migueis Joana , Cardoso Rita , Dinis Isabel , Mirante Alice

Background: Congenital hypothyroidism (CH) is an important and preventable cause of growth retardation and neurological deficit. Early treatment is crucial to minimize long term effects and today regimens tend to be more aggressive targeting hormonal control.Objective: To correlate CH severity at diagnosis with levothyroxine (LT) dosage and time needed to control TSH levels.Methods: Retrospective study including children with CH at...

Childhood Obesity Negatively Influences Adult Leydig Cell Function

Wagner Isabel V , Kloting Nora , Kiess Wieland , Soder Olle , Svechnikov Konstantin

Background: Childhood obesity is a global health problem and co-morbidities develop already during childhood and adolescence. Male obesity impacts negatively on reproductive function. Testosterone is decreased, sperm quality reduced, and the physical and molecular structure of germ cells altered in obese males. However, less is known about the role of prepubertal obesity on future reproductive function. We therefore explored Leydig cell function and reproductive potential in a...

The Effect of Exenatide on Weight and Appetite in Overweight Adolescents and Young Adults with Prader–Willi Syndrome

Salehi Parisa , Hsu Isabel , Azen Colleen G , Mittelman Steven D , Geffner Mitchell E , Jeandron Debra

Background: Prader–Willi Syndrome (PWS) is a genetic disorder associated with hyperphagia and hyperghrelinemia with major morbidity due to obesity. The aetiology of hyperphagia is unknown, but presumed to be multifactorial, and, as ghrelin is orexigenic, high levels may contribute to weight issues in PWS. Currently, there is no effective medical treatment for hyperphagia in PWS, but targeting appetite could be beneficial. Exenatide (Byetta (synthetic exendin-4); AstraZene...

Clinical and Genotypic Characterization of Simple Virilising Forms of Congenital Adrenal Hyperplasia

Cardoso Rita , Pacheco Susana , Caetano Joana Serra , Dinis Isabel , Mirante Alice

Background: Congenital adrenal hyperplasia (CAH) is a recessive disease in 90% caused by 21-hidroxilase deficiency. The clinical manifestations are related with the severity of enzyme deficiency and are classified in classical and non classical forms. The classical form is the most severe with genital ambiguity in female newborns and universal virilisation. In 75% there is also aldosterone deficiency with salt wasting.Objective and hypotheses: To describ...

Diabetic Ketoacidosis Treatment: Experience from a Paediatric Tertiary Centre (2004–2014)

Serra-Caetano Joana , Gata Lia , Dinis Alexandra , Cardoso Rita , Dinis Isabel , Mirante Alice

Background: Diabetic ketoacidosis (DKA) is a medical emergency. The most physiologic fluid/electrolytes replacement rates and insulin dosis are still controversial.Objective and hypotheses: To evaluate the effectiveness and security of DKA treatment. Our protocol consists of 2 h’ rehydration with 0.9% sodium chloride (NaCl), followed by insulin infusion (0.1 U/kg per h) associated to 0.45% NaCl with 5% glucose. Potassium is replaced with monophospha...

Newborns of Mothers with Graves’ Disease: Survey of 14 Years

Cardoso Rita , Jeronimo Monica , Caetano Joana Serra , Dinis Isabel , Mirante Alice

Background: Graves’ disease (GD) is the most common cause of hyperthyroidism in fertile woman and can cause fetal and neonatal hyper or hypothyroidism. It is associated with transplacental transfer of maternal thyrotropin receptor antibodies (TRAb).Objective and hypotheses: The main objective of this study was to characterize the neonates born to women with GD followed in a pediatric endocrinology reference unit.Method: A retr...

Clinical, molecular characterization and long-term follow-up of a patient with neonatal severe hyperparathyroidism

Padeira Goncalo , Carvalho Ana Isabel , Cavaco Branca M. , Virella Daniel , Lopes Lurdes Afonso ,

Introduction: Heterozygous inactivating mutations of the calcium-sensing receptor encoding gene (CASR) cause autosomal dominant familial hypocalciuric hypercalcemia (FHH), whereas mutations that inactivate both alleles cause neonatal severe hyperparathyroidism (NSHPT), a rare and potentially fatal disease. We present the clinical and genetic characterization of a Portuguese family with FHH/NSHPT as well as the long-term follow-up of the proband.<p class="a...
