Introduction: Serum creatinine is not enough sensitive marker for the evaluation of glomerular filtration rate (GFR). Cockcroft-Gault (CG) formula is often used to assess GFR, but it is necessary to correct original one for body surface area (BSA), adipositas, and the creatinine tubular secretion. The values of the estimated creatinine clearance and GFR are considered to Poggio reference ones according to biological parameters (age and gender). The aim of the study was to determine the difference in renal function estimation between serum creatinine and corrected CG equation according to the Poggio reference values in the arterial hypertension patients. Materials and Methods: The research included 124 patients of both gender with arterial hypertension, excluding ones with the already verified chronic kidney disease. We estimated creatinine clearance and GFR by CG method corrected for the BSA, body mass index (BMI), and the creatinine tubular secretion according to Poggio reference values. Results: There was no significant difference in both age and gender groups among patients with physiological and pathological values of the renal function determined by the serum creatinine and estimated creatinine clearance by CG equation corrected for BMI, BSA. In both age and gender groups there was significant difference among subjects with physiological and pathological values of the renal function determined by serum creatinine and estimated GFR by CG method corrected for BMI, BSA, and creatinine tubular secretion. Conclusion: There is the most striking difference in the assessment of renal function between serum creatinine and estimated GFR by CG method with three corrections (BSA, BMI, the creatinine tubular secretion). Estimated GFR by CG method with three corrections can help in the early diagnosis of renal dysfunction and optimal treatment in patients with arterial hypertension.

Introduction: Adequate prenatal and postnatal care for preterm neonates not only affects the survival rate, but also the occurrence of chronic diseases, and in the future also affects the quality of life of that children. Aim: To examine the influence of independent predictors (weeks of gestation, body weight, sex) on the outcome of the disease and to analyze the influence of the applied ventilatory mode on the final outcome of treatment. Material and methods:  The study included neonates (n = 248) born prematurely who were treated in the neonatal intensive care unit for a period of one year due to immaturity-related difficulties. Results: The mean age of male neonates (n = 119) at birth was 31.13 ± 3.3 weeks of gestation (WG), and females (n = 129) 31.59 ± 3.2 WG. Weeks of gestation have a statistically significant effect on survival (p = 0.0001), for each more week of gestation, the chances of survival increase by 21%. There was no significant difference between birth weight and sex (p = 0.289), and the birth weight of the neonates had a statistically significant effect on survival (p = 0.0001). For every 10 grams of body weight, in our sample, the chance of survival increases by 2%. Ventilation mode showed a statistically significant effect on neonatal survival (p < 0.05), and intubation mode was used as an indicator. If neonates are switched from non-invasive to invasive ventilation mode, the chance of survival in our sample is reduced by 88%. Conclusion: Weeks of gestation, birth weight, and the use of a noninvasive mode of ventilation are predictors of a positive outcome for preterm neonates.

Abstract The aim of this paper is to present a patient with the Smith-Lemli-Opitz syndrome (SLOS), with an overview of the modality of diagnosis, and the treatment of the patient. Exome analysis showed two variants in exon 6 of the 7-dehydrocholesterol reductase (DHCR7) gene have been determined: missense variant 1) NM_001360.2: c.470T>C (p.Leu157Pro) and 2) nonsense variant c.452G>A (W151*). Therefore the DHCR7 genotype of the patient is NM_001360.2: c.[470T>C; c.452G>A]. The proband, aged 6 years, has global developmental retardation with missing contact gaze and lacking motor development for her age and with peripheral spastic-enhanced muscle tone, and is under the supervision of children neurologists, gastroenterologists, nephrologists and cardiologists.

Results: After 247 ± 53 seconds (4 minutes and 11 seconds) in average patients developed NSVT, and were referred for coronary angiography. Of total number, 4 had a significant finding on coronary angiography; 3 patients had single-vessel coronary disease (one received a stent on right coronary artery (RCA), two on left anterior descending artery (LAD)), and one had triple-vessel coronary disease (received a stent on circumflex artery (CX) and LAD).

ACCEpTED: December 18, 2020 Introduction: Exercise stress test (ergometry) in pediatric cardiology practice is used to examine the condition and functional ability of the heart in children. It is performed using a bicycle ergometer or treadmill, estimating and measuring the amount of physical activity, heart rate, blood pressure values and electrocardiogram.1,2 The aim of article was to present the role and importance of exercise stress test in everyday clinical pediatric cardiac practice.
