Background: Nonclassical congenital adrenal hyperplasia (NCCAH) due to mild 21-hydroxylase deficiency is caused by mutations of the CYP21A2 gene located on chromosome 6p21.3.Objective and hypotheses: To determine cut-off for basal and stimulated 17-hydroxyprogesterone (17-OHP) levels, to evaluate CYP21A2 gene mutations frequency among Croatian NCCAH patients, to determine correlation between 17-OHP levels and genotype and to evaluate co...

Background: Neonatal TSH screening program for congenital hypothyroidism (CH) in Central Serbia was introduced in 1983. Over the past three decades, increasing overall incidence rate of children with both permanent and transient forms of CH has been observed.Objective and hypotheses: The aim of the study was to compare incidence of CH in the first 16 years of screening (period 1) with the last 15 years of screening (period 2). We also investigated the im...

Background: There are a lot of reasons for missing the diagnosis in neonatal screening for congenital hypothyroidism (CH), but errors in processing samples and reporting results are the most frequent! In Central Serbia screening for CH was instituted in 1983 by determination of the TSH level in dried filter-paper blood spots. All samples are analyzed at one central laboratory. The average number of specimens that are annually screened is 50 000. The screening process was divid...

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases caused by a deficiency of enzymes responsible for the steroidogenesis. The most common cause is 21-hydroxylase deficiency. There are three forms of CAH due to 21-hydroxylase deficiency: the classic form with salt loss, the classic virilizing and the non-classical form. In pediatric age, CAH is most often manifested by masculinization of the genitals of female newborns, adrenal crisis or premature p...

Introduction: in countries with highly developed health information systems (HIS), early detection of short stature (SS) is facilitated by automated anthropometric calculations, with warning alarms and automated referrals when prespecified conditions are met (poor growth velocity etc.). In countries where available HIS resources are insufficient for implementation of complex automated systems for growth supervision, much simpler, graphical-based growth electro...

Background: Low birth weight is associated with increased cardio-metabolic diseases in adulthood. Specific circulating miRNA seem to be predictive of cardio-metabolic risk.Objective: Our aim was to investigate the circulating levels of mir-122, mir-16, mir-126, and mir-486 in a cohort of SGA and AGA subjects, evaluated longitudinally in childhood and early adulthood.Method: Anthropometric and biochemical-metabolic evaluations were ...

Introduction: Dichotomous nature of current definition of metabolic syndrome (MS) in youth results in loss of information. On the other hand, the complex calculation of continuous MS scores using standardized residuals in linear regression (Z scores) or factor scores of principal component analysis (PCA) is demanding and highly impractical for clinical use. Recently, a novel, easily calculated continuous MS score called Pediatric siMS score (PsiMS score) was developed based on...

Introduction: GnRH test is standard in confirming the diagnosis of central precocious puberty (CPP). However, GnRH (Relefact) is not always readily available in Serbia and several other countries. Two studies so far have assessed use of triptorelin in diagnosing CPP, with different sampling protocols, and in only one of these studies were triptorelin test findings compared to GnRH test findings.Objective: To evaluate the diagnostic accuracy of triptoreli...

Background: Cystic fibrosis related diabetes (CFRD) is one of the most common complications of CF. CFRD has great impact on progressive deterioration of lung function, poor growth and increased mortality. The need for early detection of disturbance in glucose metabolism was recognized long ago. Current recommendations include screening that begins at age of 10 by performing oral glucose tolerance test (OGTT) but it cannot reveal the initial glucose disturbances. Many centres a...

Background: Congenital hypogonadotropic hypogonadism (HH) is a rare but clinically and genetically heterogeneous disease characterized by an absent or incomplete puberty and infertility. The association of HH with hyposmia or anosmia is defined as Kallmann syndrome. Molecular genetic testing of HH is valuable, as it can prompt the treatment in adolescence.Objective and hypotheses: To identify causative variants in genes associated with HH in a cohort of ...
