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...

Objectives: To investigate changes in levels of autoantibodies(Abs) against 21-hydroxylase(21OH) in APECED patients and in patients with isolated primary autoimmune adrenal insufficiency (AI) over time after manifestation of AI.Methods: 24 patients with APECED with AI and 5 patients with isolated autoimmune AI were recruited. APECED was confirmed by finding at least two major components of the disease and/or two mutation...

Objectives: To investigate sensitivity, specificity and predictive values (PPV, NPP) of autoantibodies against 21-hydroxylase in APECED patients with and without adrenal insufficiency (AI) and in patients with other forms of AI.Methods: 42 patients with APECED and 24 patients with other forms of AI were recruited. APECED was confirmed by finding at least two major components of the disease and/or two mutations in AIRE gene and/or high levels of antibodie...

Background: Insulinomas are extremely rare tumors in children and an uncommon first manifestation of the MEN1 syndrome. An early clinical and genetic diagnosis is very important for the appropriate medical assessment and family counseling. In children, insulinomas are usually benign tumors with only a few reports of malignant cases.Objective and hypotheses: To investigate clinical features, genetic and morphological characteristics of 12 children with pr...

Context: Children with 21-hydroxylase deficiency (21OHD) require chronic glucocorticoid administration to substitute glucocorticoids and suppress adrenocorticotropic hormone-induced hyperandrogenemia. There is still no evidence about the best timing of the highest hydrocortisone (HC) dose. Administration of the highest dose in the morning aims to mimic the physiological rhythm of cortisol, while a high dose late in the evening may inhibit the early-morning inc...

Background: A new classification of pseudohypoparathyroidism is available (Thiele et al. 2016, J Endocrinol). The phenotype variability of inactivating PTH/PTHrP Signaling Disorders (iPPSD, former pseudohypoparathyroidism) cases is still very challenging, even for experts. Thus, it is crucial to collect data in a centralized manner for future investigation.Methods: The EuRRECa/EuRR-Bone registries are the first ...

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...
