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...

Sertoli-Leydig Cell Tumor as a Rare Cause of Hirsutism in a Young Adolescent

van der Straaten Saskia , Merckx Mireille , Van Dorpe Jo , Goethals Inge , Bordon Victoria , Timmers Philippe , De Schepper Jean

Background: Sertoli-Leydig Cell Tumors (SLCT) account only for 1% of all ovarian neoplasia, occur more commonly in the second or third decade of life and seldom secrete tumor markers. The experience in adolescence is limited.Objective and hypothesis: To report the hormonal and biological profile of a SCLT in a young adolescent. Ovarian tumor markers as well as FDG-PET scanning might be helpful in diagnosing ovarian malignancy in case of normal ultrasound...

Off-label use of cinacalcet in pediatric primary hyperparathyroidism: a French multi-centre experience

Bernardor Julie , Flammier Sacha , Salles Jean-Pierre , Castanet Mireille , Martinerie Laetitia , Lienhardt-Roussie Anne , Amouroux Cyril , Linglart Agnes , Bacchetta Justine ,

Background: For adult patients who do not meet indications to surgery, the calcimimetic cinacalcet is approved for primary hyperparathyroidism (HPT), decreasing calcium and parathyroid hormone (PTH) levels. This drug is largely used in adults, but may be a challenge in daily practice in children, because of the risk of hypocalcemia, increased QT interval and drug interactions. A few pediatric cases have highlighted its potential interest in children with HPT; ...

Salivary sex steroids as markers of puberty in boys during late childhood and adolescence

Patjamontri Supitcha , Spiers Alexander , Smith Rachel B , Shen Chen , Adaway Jo , G Keevil Brian , Toledano Mireille B , Ahmed S Faisal ,

Introduction: Salivary androgens represent a non-invasive marker of puberty that may have utility in population studies as well as in the clinical arena.Objectives: To establish normal reference values of salivary androgens using LC-MS/MS and demonstrate the correlations between salivary androgens and pubertal development in boys.Methods: School-based adolescent cohort study with t...

Resistance to Thyroid Hormone Alpha Associated with Early-Onset Severe NASH

Pautasso Valentina , Dumant-Forrest Clémentine , Guerrot Anne-Marie , Fraissinet François , Savagner Frédérique , Castanet Mireille

Introduction: Resistance to thyroid hormone alpha (RTHα) is characterised by tissue-specific hypothyroidism associated with barely normal thyroid function tests. Clinical features include dysmorphic facies, skeletal dysplasia, growth retardation, constipation, dyspraxia and intellectual deficit. Hormonal assessment often shows decreased/low-normal free thyroxine (fT4) and increased/high-normal free triiodothyronine (fT3) concentrations, resulting in a low...

Mast Cells and Steroidogenesis in the Human Fetal Adrenal

Naccache Alexandre , Louiset Estelle , Duparc Celine , Laquerriere Annie , Patrier Sophie , Renouf Sylvie , Gomez-Sanchez Celso E. , Mukai Kuniaki , Lefebvre Herve , Castanet Mireille

Background: We recently demonstrated the presence of mast cells in human fetal adrenal gland from 18–20 weeks of gestation (WG) within the subcapsular layer. In the adult adrenal, mast cells have been implicated in mineralocorticoid synthesis and secretion especially in aldosterone-producing adenomas. Because similarities exist between tumors and normal fetal development and as cell-to-cell interactions involving immune cells are implicated in organogenesis, we hypothesiz...

Clinical Radiographic and Biochemical Findings of Three Patients with Hypophosphatasia Carrying the Same Mutation

Orbak Zerrin , Orbak Recep

Background: Hypophosphatasia (HP) is a rare inherited disorder characterized by defective bone and tooth mineralization and caused by deficiency in the tissue non-specific alkaline phosphatase gene (ALPL). The symptoms are remarkably variable in their clinical expression, and relate to numerous mutations in this gene.Aim: The purpose of this study was to document the clinical, biochemical and radiologic aspects of the th...

Comparison of the Effectiveness of a Battery Powered and Manual Toothbrush in Removal of a Dental Plaque for Good Oral Hygiene in Adolesents with Over-Weight

Orbak Recep , Orbak Zerrin

Objective: Dental plaque removal is an important factor in preventing periodontal diseases and caries. Tooth brushing remains the most reliable method of controlling dental plaque. The purpose of this study was to compare the effectiveness of plaque control performed with a battery powered and manual toothbrushes in over-weight adolescents.Materials and methods: The twenty two adolesents with over-weight were attended in this study. These patients were d...

The Effects of Serum Insulin, Leptin, Ghrelin, Adiponectin and Resistin Levels on Early Postnatal Growth in Small for Gestational Age Newborns

Orbak Zerrin , Kara Mustafa

Background: Adipose tissue acts as an endocrine organ, secreting biologically active molecules in response to external stimuli or lipid overloading. These adipose tissue-derived signaling molecules include adipokines such as leptin, adiponectin and resistin (4). On the other hand, ghrelin is the hunger hormone and an endogenous growth hormone secretagogue.Objective and hypotheses: This study aimed to investigate the relation between weight gain and serum...

The Effects of Serum Leptin, Ghrelin, Adiponectin and Resistin Levels on Early Postnatal Growth in Infants of Diabetic Mothers

Kara Mustafa , Orbak Zerrin

Background: The exact mechanisms on growth are not fully eluciated, but they involve insulin resistance, fetal hyperleptinemia, hypothalamic changes. The adipose tissue-derived signaling molecules include adipokines such as leptin, adiponectin and resistin. On the other hand, ghrelin is the hunger hormone and an endogenous growth hormone secretagogue.Objective and hypotheses: This study aimed to investigate the relation between growth and serum insulin, ...
