Background: MKRN3 gene, encoding Makorin RING-finger protein 3, is a maternally imprinted gene located at a Prader-Willi syndrome region on chromosome 15q11.13. Deleterious mutations of MKRN3 gene are a common cause of paternally inherited central precocious puberty (CPP), being identified in 33-46% of familial cases and in about 5% and 40% of apparently sporadic female and male cases, respectively.Objectives: To evaluate the presence o...

Introduction: The major genetic cause of CPP is the paternally inherited Makorin RING-finger protein 3 (MKRN3) deficiency. Rare patients carry variants in kisspeptin and its receptor and DLK1.Objectives: To identify genetic causes of CPP.Population and methods: MKRN3 Sanger sequencing was performed in 56 unrelated subjects (12 familial non-maternal, 44 sporadic (6 boys)), whole-ge...

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...

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...

Objectives: Thiamine responsive megaloblastic anemia syndrome (TRMA) is characterized by the clinical triad of megaloblastic anemia, non-immune diabetes mellitus and sensorineural deafness. It is a very rare autosomal recessive disease with an increased frequency in consanguineous marriages and isolated communities. The syndrome is due to intracellular thiamine deficiency which is the result of a defective high affinity low performance thiamine transporter pro...

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: Primary generalized glucocorticoid resistance (PGGR) is a rare genetic condition characterised by generalised, partial target-tissue insensitivity to glucocorticoids owing to inactivating mutations of the NR3C1 gene.Case presentation: An 8.5-year-old boy was hospitalized because of precocious puberty and arterial hypertension. Over the last year, the appearance of pubic hair and gynecomastia were noted. At the local centre, high leve...
