Background: Congenital hyperinsulinism (CHI) is the most common cause of the persistent hypoglycemia in children. Mutations in KCNJ11 and ABCC8 genes coding potassium channel subunits are responsible for a significant proportion of CHI patients. The type of mutation correlates with the type of B-cell hyperplasia (focal or diffuse), and determinates further diagnostics, treatment and prognosis of disorder.Aims and objectives: The aim of ...

Background: Immunoglobulin superfamily, member 1 (IGSF1) was originally proposed to function as an inhibin co-receptor in pituitary gonadotroph cells. More recently, however, loss of function mutations in the human IGSF1 gene were linked to a novel syndrome of central hypothyroidism, testicular enlargement, and variable prolactin-deficiency. Igsf1-deficient mice are also centrally hypothyroid, with reduced pituitary thyrotropin-releasing hormone receptor (<em...

Background: In total of 48,XXYY Syndrome occurs in 1:20.000–1:50.000 male births. It used to be considered as a variant of Klinefelter syndrome, but now it is considered as a distinct clinical and genetic entity with increased risks for congenital malformations, additional medical problems and more complex psychological and neurodevelopmental involvement. 48,XXYY Syndrome results from the fertilization of a normal female oocyte (Xm), with an aneuploid sperm (XpYpYp) produ...

Introduction: Beta thalassemia is a common genetic disorder in Mediterranean countries. Congenital hypothyroidism is also a condition resulting with deficiency of thyroid hormone in newborn infants. Autoimmune thyroid dysfunction in childhood patients with thalassemia major is uncommon and poorly described. We report a case of a child with two independent diseases - clinical hypothyroidism diagnosed in early childhood, and beta thalassemia major who developed ...

Background: McCune–Albright syndrome (MAS) is defined by skin, bone and glands disorders, due to activating mutations in the GNAS1. Clinical presentation is heterogeneous. Reports about GH excess in MAS patients are scarce.Case report: We present the case of an 8-year-old male, previously diagnosed with mono-ostotic fibrous dysplasia of the skull, referred due to signs of pubertal development since the age of 6. The patient presented only 1...

Background: Chronic diseases are the main causes of bone mass reduction in childhood and adolescence. Different aspects related to the process of bone acquisition and maintenance may be affected. Studies had point out the presence of bone mass reduction in children and adolescents with HIV infection with association to antiretroviral use, chronological age (CA), weight and serum CD4 T-cell counts. However, others do not.Objective: To evaluate bone minera...

Background: Central precocious puberty (CPP) is a common condition in girls and has been associated with deterioration of final height (FH). Height prognosis (HP) is critical for the decision of treatment in CPP. There are several methods for predicting FH in CPP but none is completely reliable. Most methods consider bone age (BA), which is very imprecise, but there is no consensus on which method is the best to estimate FH.Objective: To compare the accu...

Background: Congenital pituitary hormone deficiency is etiologically heterogeneous and occurs in 1:4000 live births. Of those, isolated GH deficiency (IGHD) is the most common, followed by combined pituitary hormone deficiency with or without extrapituitary anomalies.Objective and hypotheses: Description of a patient with IGHD, associated with multiple additional organ anomalies.Method: Case report, Sequencing of HESX1, SOX2</e...

Background: Germline mutations in fibroblast growth factor receptor (FGFR) genes 1–3 can cause skeletal dysplasias such as achondroplasia (ACH), which is caused primarily by a G380R substitution in FGFR3. Infigratinib (BGJ398), a potent and selective FGFR1–3 tyrosine kinase inhibitor (TKI), demonstrated preclinical efficacy at low doses in an ACH mouse model. The objective of this analysis is to evaluate dose dependency and toxicity...

Background: Non-alcoholic Fatty Liver Disease (NAFLD) is a frequent complication of obesity in both adults and children and there is an alarming increase in prevalence of both. Studying of risk factors for NAFLD in children and adolescents might help to select vulnerable groups to start an early intervention.Objectives: The aim of our study was to detect the prevalence of NAFLD in pediatric obese patients (0-18.9 years, ...
