Background: Intrauterine growth retardation (small for gestational age (SGA)) is connected with perinatal morbidity, neurological pathology and stature.Objective and hypotheses: The aim of our study is to estimate the incidence of SGA and its consequences in newborns and infants at the age 1.Method: The incidence of SGA among newborns in the Udmurt Republic (the region of the European part of the Russian Federation) has been studie...

Background: Childhood obesity is one of the most important causes of end-stage renal disease. The onset of obesity-associated renal disease is insidious and asymptomatic. To date available markers do not perfectly mimic kidney injury and may not characterize kidney changes especially in early stages and of renal tubulointerstitium. Tubular changes (KIM-1 and NGAL) are already apparent before the onset of proteinuria or alterations of GFR and thus might represent biomarker that...

Background: Childhood obesity is associated with non-alcoholic fatty liver disease (NAFLD). Previous studies in obese adult and pubertal children with NAFLD have shown that chronic inflammation/oxidative stress and insulin resistance might induce iron metabolism disorders, characterized by increased Hepcidin and Ferritin levels and decreased serum Iron levels. However, data evaluating these findings in a well selected population of obese prepubertal children are still missing....

Background: Impaired linear growth and low IGF1 levels, strictly related to poor glycemic control have been reported in children with type 1 diabetes (T1DM).Objective and hypotheses: We studied growth and growth factors in 91 T1DM young patients, 54 males (age: 11.73±3 years, disease duration: 5.2±2.9 years). All subjects were on intensive insulin therapy: 72 children by multiple injection therapy (MI), 19 children by continuous subcutaneous in...

Background: Hyperinsulinemic hypoglycemia is a heterogeneous condition characterized by inappropriate insulin secretion in the presence of low blood glucose levels. It can have various causes, including genetic, metabolic, syndromic, autoimmune, insulinoma, non-insulinoma pancreatogenous hypoglycemia or non-islet cell tumor hypoglycemia. On the other hand, oculofaciocardiodental syndrome is a rare X-linked dominant condition characterized by multiple congenita...

Introduction: Central hypothyroidism is due to a deficiency of TRH/TSH.Patient and Methods, Results: A 9 year old boy (07 Aug. 20) was referred for proportionate short stature (-2.7 SD). He complained of fatigue and had mild peripheral edema. His baseline T4 was 2.9 ug/dL(ref. 4.50-12.50 ug/dL) and TSH 0.04 uIU/ml (0.400-4.00). The TRH test showed low TSH <0.004 Ulu/ML (ref. 0.400-4.00) and low T4 2.70 (ref. 4.50-12....

Background: CHARGE is an autosomal-dominant syndrome which includes a variable combination of coloboma of the eye, heart malformations, atresia of the choanae, retardation of growth and development, and genital and ear abnormalities CHARGE syndrome has rarely been associated with anterior pituitary dysfunction and with structural abnormalities of the pituitary gland only twice. We report the case of a child with CHARGE association and congenital hypopituitaris...

Background: Transient neonatal adrenal dysfunction is reported in association with antiretroviral therapy with Lopinavir and Ritonavir. Other drugs have not been tested.Objective and hypotheses: We report on a preterm girl, born 26 weeks gestation, with elevated 17-hydroxyprogesterone (17OHP) at newborn screening. During pregnancy the mother was treated for HIV with Atripla (Efavirenz, Tenofovir, Emtricitabin) and viral load was suppressed. Furthermore t...

Background: Nephrogenic diabetes insipidus (NDI) is caused by inability of renal collecting duct cells to respond to arginine vassopresin (AVP)/antidiurethic hormone (ADH).Objective and hypotheses: The majority of patients (about 90%) have type 1, X-linked recessive form, of NDI caused by mutation in gene encoding the vassopresin V2 receptor. Type 2, autosomal NDI, have the rest 10% of patients. This type is caused by the aquaporin-2 water channel (AQP2)...

Background: Several years ago, we developed a recombinant cell bioassay to determine serum estrogenic bioactivity (EBA). In addition to its physiological interest, EBA could be a good marker of endocrine-disrupting compounds (EDCs) with estrogenic activity and thus would be useful in the field of environmental-related endocrine diseases.Aims and objectives: To characterise the type of substances that mediate estrogenic activity.Met...
