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...

Congenital Adrenal Hyperplasia caused by homozygous pathogenic variant in the HSD3B2 gene.

Fylaktou Eirini , Christoforidis Athanasios , Moutsanas Vissarios , Sertedaki Amalia , Kanaka-Gantenbein Christina ,

Introduction: Congenital Adrenal Hyperplasia (CAH) is an autosomal recessive disorder caused by impairment of one of the enzymes involved in the steroidogenesis pathway. 3βhydroxysteroid dehydrogenase type 2 deficiency (3βHSD2 deficiency) is a rare form of CAH (<0.5%) due to pathogenic variants in the HSD3B2gene encoding for the enzyme Type 2 3β-hydroxysteroid dehydrogenase Δ4–Δ5isomerase (3&#946...

Compound heterozygous variants in ROBO1 gene cause CPHD and middle line defects

Sertedaki Amalia , Macropoulou Panagiota , Nikaina Eirini , Binou Maria , Farakla Ioanna , Siahanidou Tania , Kanaka-Gantenbein Christina

Abstract: Combined Pituitary Hormone Deficiency (CPHD) is characterized by growth hormone and at least one other pituitary hormone deficiency. It is of varying etiology, extent and severity and it usually occurs sporadically with only 10% of cases being familial. Although pathogenic variants in more than 30 genes expressed during the development of the head, hypothalamus and/or pituitary have been identified so far to cause genetic forms of CPHD, the aetiology...

Kenny Caffey syndrome 2; expanding the clinical spectrum

Hatziagapiou Kyriaki , Sertedaki Amalia , Dermentzoglou Vasiliki , Kanaka-Gantenbein Christina , D. Sakka Sophia

Background: Kenny–Caffey syndrome 2 (KCS 2) is a rare cause of hypoparathyroidism, characterized by proportionate short stature, cortical thickening and medullary stenosis of tubular long bones, delayed closure of anterior fontanel and eye abnormalities.Objective: We report the case of a 4-years’-old boy, who presented with the characteristic, and newly identified clinical, biochemical, radiological and genet...

Introduction – Scope: Childhood cancer has an impact on the neurocognitive functions of growing children and adolescents. The aim of this study, which is the first of its kind in Greece, was to examine the differences in neurocognitive abilities between children and adolescents survivors of brain tumors (BT), and survivors of other types of cancer.Method: Study participants were cancer survivors aged 7 to 15 years,...

Whole Exome Sequencing (WES) Reveals Oligogenic Gene Mutations in a Case of Combined Pituitary Hormone Deficiency (CPHD)

Sertedaki Amalia , Tatsi Elizabeth-Barbara , Nikaina Eirini , Vasilakis Ioannis Anargyros , Fylaktou Irene , Iacovidou Nicoletta , Siahanidou Soultana , Kanaka-Gantenbein Christina

Introduction: CPHD is characterized by GH and at least one other pituitary hormone deficiency. Mutations in genes expressed in the developing head, hypothalamus, and/or pituitary cause CPHD. To date around 30 genes have been identified to be related to CPHD, however the 85% of the cases remain with unknown aetiology. Whole Exome Sequencing (WES) enables parallel searching for pathogenic variants of CPHD in targeted known gene panels as well as the identifi...

Menstrual Cycle Disorders in Young Women with Type 1 Diabetes Mellitus

Paschou Stavroula A , Vryonidou Andromachi , Melissourgou Marina , Kosteria Ioanna , Anagnostis Panagiotis , Goulis Dimitrios G , Chrousos George P , Kanaka-Gantenbein Christina

Background and aim: Epidemiologic observations suggest that women with type 1 diabetes mellitus (T1DM) often suffer from menstrual cycle disorders. There may also be a negative association between the age of onset of T1DM and the age of menarche. Delayed menarche, in turn, may be associated with increased risk for diabetic complications. The aim of this study was to prospectively investigate pathologic manifestations of reproductive function in young women with T1DM and their ...

Background: Maturity Onset Diabetes of the Young (MODY) constitutes a genetically and clinically heterogeneous type of Monogenic Diabetes (MD). It is characterized by early onset, autosomal dominant inheritance and a defect in β cell insulin secretion. To date 14 different MODY subtypes have been reported each one with a distinct genetic aetiology. However four are the most common subtypes, namely MODY 1 (HNF4A), MODY2 (GCK), MODY3 (HNF1A), MODY...

Seasonality of Type 1 Diabetes in Children and Adolescents According to Date of Diagnosis and Date of Birth in a Large Diabetes Centre

Vasilakis Ioannis Anargyros , Kosteria Ioanna , Tzifi Flora , Christopoulos-Timogiannakis Evangelos , Kotrogianni Paraskevi , Chrousos George , Kanaka-Gantenbein Christina

Background: There are studies supporting the seasonality of diabetes according to date of diagnosis and date of birth, with most T1D children being diagnosed in fall and winter and most of them been born in the same period. That is in concordance with previously published data from 1978 to 2008 in our country.Objective and hypotheses: To assess whether there is a seasonal variation of diabetes onset according to date of diagnosis and date of birth of inc...
