Background: Osteogenesis imperfecta (OI) due to COL1A1 and COL1A2 mutations is the most common cause of primary osteoporosis.Case presentation: We present a 10-year-old girl with a history of skeletal fragility, starting in the perinatal period. Her parents are not consanguineous and there is no family history of early osteoporosis. To date, she has sustained nineteen low-energy, long bone fractures and she has skeletal deformities (leg length discrepanc...

Occasional Detection of an Adrenal Incidentaloma in a Female Adolescent Evaluated for Cardiac Arrhythmias

Kotanidou Eleni , Kyrgios Ioannis , Mouzaki Konstantina , Kleisarchaki Angeliki , Koliatos Panagiotis , Galli-Tsinopoulou Assimina

Background: Adrenal incidentalomas(AIs) are adrenal masses discovered occasionally by radiological evaluation in the absence of clinical features of adrenal disease. Clinical evaluation is important in patients with AIs. AIs are bilateral (10–15%); manifest as nonfunctioning cortical adenomas (70–80%), pheochromocytomas (1.1–11%), subclinical Cushing syndrome (5–20%), primary aldosteronism (1–2%), primary adrenocortical carcinomas (<5%) and metasta...

L-selenomethionine Supplementation in Children and Adolescents with Autoimmune Thyroiditis: Preliminary Results of a Randomized Double-blinded Placebo-controlled Clinical Trial

Kyrgios Ioannis , Dimopoulou Aikaterini , Kotanidou Eleni , Kleisarchaki Angeliki , Mouzaki Konstantina , Galli-Tsinopoulou Assimina

Background: It has already been documented that selenium treatment has beneficial effects in adult patients with autoimmune thyroiditis, especially in those with a higher titer of antibodies and increased inflammatory disease activity.Objective and hypotheses: To investigate whether daily supplementation of organic selenium at a high dose (200 μg in the form of L-selenomethionine) has any effect on the titer of thyroid autoantibodies.<p class="a...

Seasonality of Month of Birth in Children and Adolescents with Hashimoto Thyroiditis

Kyrgios Ioannis , Giza Styliani , Kotanidou Eleni , Maggana Ioanna , Galli-Tsinopoulou Assimina

Background: A number of studies have previously described seasonality of birth in children with type 1 diabetes, thus suggesting that the autoimmune process may begin during fetal development. However, there is a lack of data regarding autoimmune thyroid disease in childhood.Objective and hypotheses: The aim of this study was to analyse the seasonal birth month pattern in young patients with Hashimoto thyroiditis and compare it with that of youth healthy...

Osteoprotegerin and Insulin Resistance in Childhood Obesity: A New Interplay?

Kotanidou Eleni , Kyrgios Ioannis , Karalazou Paraskevi , Maggana Ioanna , Tzimagiorgis Georgios , Galli-Tsinopoulou Assimina

Background: A positive association between osteoprotegerin (OPG) levels and cardiovascular morbidity and mortality has been recently reported. Additionally, there is evidence that OPG in obese adults participates in the pathogenesis of atherosclerosis and cardiovascular diseases by promoting inflammation, which is known to be linked to insulin resistance (IR). There is few data regarding the relationship among obesity-IR-OPG, in youth.Objective and hypot...

Imbalance Between Pro-Oxidative and Anti-Oxidative Mechanisms in Children and Adolescents with Type 1 Diabetes Mellitus

Karampali Maria , Kyrgios Ioannis , Kalogiannis Stavros , Efstratiou Efthimia , Galli-Tsinopoulou Assimina

Background: Type 1 diabetes mellitus (T1DM) has been described to be associated with altered oxidative status. Combined analysis of pro-oxidative and anti-oxidative mechanisms in youngsters with T1DM has been less studied.Objective and hypotheses: To evaluate pro-oxidative/anti-oxidative status in T1DM youngsters and healthy controls and investigate their possible association with glycemic control.Method: Sixty-three children and a...

No Association Between Serum Vitamin D and Left Ventricular Mass Index in Children and Adolescent with Type 1 Diabetes Mellitus

Klissarhaki Angeliki , Papadopoulou-Legbelou Kyriaki , Kyrgios Ioannis , Eboriadou-Petikopoulou Maria , Galli-Tsinopoulou Assimina

Background: Vitamin D deficiency has been associated with left ventricular geometry and hypertrophy and larger end-systolic diameters and worse left ventricular function in animals and humans.Objective and hypotheses: The aim of this study was to investigate any possible association between vitamin D levels and geometry of left ventricle (LV) in youngsters with type 1 diabetes mellitus (T1DM).Method: 58 youngsters with T1DM with me...

CpG Methylation Changes within the INS, HLA-G and PTPN-22 Promoters in Childhood Type 1 Diabetes

Kyrgios Ioannis , Mouzaki Konstantina , Spandonidis Theodoros , Fragou Aikaterini , Tzimagiorgis Georgios , Eboriadou-Petikopoulou Maria , Galli-Tsinopoulou Assimina

Background: Alterations in DNA methylation status of specific genetic loci may affect gene expression, thus leading to autoimmunopathies.Objective and hypotheses: This study aimed to investigate possible differences in DNA methylation pattern between type 1 diabetes mellitus (T1DM) youngsters and healthy controls.Method: Ten T1DM participants and 10 age-/gender-matched controls were enrolled. DNA was extracted from white blood cell...

Serum fibroblast growth factor 21 (FGF-21) levels of children and adolescents with Hashimoto’s thyroiditis, before and after L-thyroxin medication

Drongitis Pavlos , Kotanidou Eleni P , Serbis Anastasios , Tsinopoulou Vasiliki Rengina , Gerou Spyridon , Galli-Tsinopoulou Assimina ,

Background: Fibroblast growth factor 21 (FGF-21) is a complex molecule involved in lipid and glucose metabolism. FGF-21 shares biochemical pathways and sites of action with thyroid hormones. Current data correlate FGF-21 levels to thyroid function. The aim of the present study was to investigate possible associations among FGF-21 levels, resting metabolic rate (RMR), lipidemic profile and L-thyroxin replacement therapy treatment in children and adolescents wit...

Do perinatal history and mode of delivery affect age at menarche? Preliminary data of girls with Greek origin

Tsinopoulou Vasiliki-Rengina , P. Kotanidou Eleni , Bacopoulou Flora , Fidani Liana , Galli-Tsinopoulou Assimina , Christoforidis Athanasios

Objectives: Age at menarche depends on genetic, environmental, epigenetic and other factors. Studies have shown that aspects of perinatal history, including birth weight, mode of delivery (caesarian section or vaginal delivery) and gestational week at birth influence the onset of puberty. The purpose of this study was to record the age at menarche in a sample of Greek girls and to correlate it with their perinatal history, the mothers’ age at menarche, t...
