Acute Phase Proteins and Endocrine Dysfunction after Traumatic Brain Injury in Childhood

Verigaki Olga , Papassotiriou Ioannis , Prodromou Neofytos , Sfakianos George , Chrousos George , Kanaka-Gantenbein Christina

Background: Endocrine impairments, such as diabetes insipidus (DI), growth hormone deficiency (GHD) and, to a lesser degree, thyroid or cortisol deficiencies, have been reported after traumatic brain injury (TBI) in adults and much less in children both at the acute post-traumatic phase and after a lag period of time. However, no prospective data exist on the endocrine and acute phase protein response to TBI in childhood.Aim/objective: To unravel possibl...

Body Composition Parameters, Systemic Inflammation and Metabolic Syndrome Manifestations in Children and Adolescents

Christaki Eirini , Pervanidou Panagiota , Bastaki Despoina , Valavani Eleni , Kanaka-Gantenbein Christina , Boschiero Dario , George Chrousos

Introduction: Increased adiposity has been associated with smoldering systemic inflammation and metabolic syndrome manifestations, leading to further morbidity by increasing the risk for type 2 diabetes mellitus and cardiovascular disease in adults. Similar analyses have not been performed systematically in children and adolescents.Hypothesis: This study investigates the interrelations between body composition parameters and indices of inflammation and m...

Search for Genetic Defects in the Transcription Factor Genes FOXL2, FOXE1, BMP15, NOBOX, and GDF9 in Children, Adolescents and Young Adults With Premature Ovarian Insufficiency POI

Settas Nikolaos , Anapliotou Margarita , Deligeoroglou Euthimios , Kanavakis Emmanuel , Fryssira Eleni , Kanaka-Gantenbein Christina , Michala Lina , Dacou-Voutetakis Catherine , Creatsas George , Chrousos George P , Voutetakis Antonis

Background: Molecular defects are rarely detected in Premature ovarian insufficiency (POI) patients.Objective and Hypotheses: We hypothesized that the frequency of causative molecular defects could be higher in cases with early onset of POI. Moreover, the analysis of multiple genes in the same POI group could disclose co-existence of more than one molecular aberration.Method: In 25 subjects, aged 17.1±7 years at POI onset, bid...

Phenotype and Clinical Course in Three Individuals with Multiple Endocrine Neoplasia Type 2A due to a RET Gene Mutation

Panou Evangelia , Chrousos George

Background: Mutations in the RET gene have been described in subjects with multiple endocrine neoplasia Type 2 (MEN 2A). MEN 2A is a rare autosomal dominant disorder characterized by tumors of the C cells of the thyroid, adrenal medulla and parathyroid glands. Patients develop either C-cell hyperplasia or medullary thyroid cancer, pheochromocytoma, and in some cases hyperparathyroidism.Objective/Method: To descr...

Functional Characterization of a Novel Heterozygous Point Mutation in the Human Glucocorticoid Receptor Gene Causing Primary Generalized Glucocorticoid Resistance

Nicolaides Nicolas C , Vlachakis Dimitris , Sertedaki Amalia , Kossida Sophia , Chrousos George P , Charmandari Evangelia

Background: Primary generalized glucocorticoid resistance (PGGR) or Chrousos syndrome is a rare familial or sporadic condition caused by mutations in the hGR gene, which reduce tissue sensitivity to glucocorticoids. A new case of PGGR caused by a novel heterozygous point mutation in the hGR gene, which resulted in threonine (T) to isoleucine (I) substitution at amino acid position 556 in the ligand-binding domain of the receptor, was recently reported in a patient with an adre...

An Unusual Case of Hypophosphatemia in a Child Affected by Di George Syndrome

Kalapurackal Mila Ann , Barzaghi Federica , Pitea Marco , Cassano Gilda , Weber Giovanna

A female child born from non consanguineous parents of Pakistani origin presented with congenital heart anomaly at prenatal ultrasound and confirmed at birth, with type B aortic arch interruption, right-sided aortic arch, wide ventricular and atrium septum defects, which required repeated surgical corrections during the first 9 months of life. The ultrasound also reported absence of the thymus. Suspecting Di Deorge Syndrome, a fluorescent in situ hybridization (FISH) ...

Electromagnetic Fields Exposure in Adolescents: A Survey in 11-14 y Old Greek Students

Geronikolou Styliani , Chrousos George , Kanaka-Gantenbein Christina

Background: Electromagnetic field (EMF) exposure has been considered a potential environmental toxicant, which may influence endocrine and other functions, while population awareness remains limited. In an earlier study, we demonstrated that EMF alters the hypothalamic-pituitary-adrenal axis in children using a 3G mobile telephone.Aim: To screen and compare the motives, knowledge and status of electromagnetic field expos...

Near Electromagnetic Fields – Induced Syndrome: Unsuspected and Newly Recognised

Geronikolou Styliani , Chrousos George , Kanaka-Gantenbein Christina

This present study investigates the impact of a common environmental hazard, the radiofrequency fields (RF), such as those regarding cell phones, cell phone base stations, wi-fi, portable phones (DECT), etc., as close to the body sources of exposure, on endocrine function. This is of importance, particularly for developing children, that have been and are exposed to this potential hazard. We performed analyses on endocrine assessments regarding stress, thyroid hand reproductiv...

Whole Exome Sequencing in Patients with Primary Generalized Glucocorticoid Resistance Identifies a Novel TRIM28 Gene Mutation (p.R230X)

Sertedaki Amalia , Marinakis Nikos , Nicolaides Nicolas C. , Crousos George , Charmandari Evangelia

Introduction: Primary Generalized Glucocorticoid Resistance or Chrousos syndrome (CS) is a rare sporadic or familial disorder characterized by generalized, partial tissue insensitivity to glucocorticoids. Mutations of the NR3C1 gene, which encodes the human glucocorticoid receptor, have been identified in many but not all patients with CS.Objective: To identify novel genes related to CS in patients without NR3C1 gene mutations.<p cl...

Vitamin D may facilitate Clock/Bmal1-DNA interactions in a Vitamin D receptor-independent fashion

Nicolaides Nicolas , Papakonstantinou Eleni , Vlachakis Dimitrios , Chrousos George

Background: The Clock/Bmal1 transcription factor heterodimer regulates the circadian activities of many biological systems, including the hypothalamic-pituitary-adrenal (HPA) axis, by trans-activating or trans-repressing downstream target genes. 1,25 Dihydroxy Vitamin D (Vitamin D), a sterol hormone that is activated by exposure to sunlight, plays a fundamental role in maintaining calcium and phosphorus homeostasis. Recent evidence suggests that the nuclear vi...
