OUR EXPERIENCE WITH CONTRAST-ENHANCED VOIDING UROSONOGRAPHY.

Vesicoureteral reflux (VUR) is one of the most common anomalies of the urinary system in children. Contrast-enhanced voiding urosonography (ceVUS) is one of the best methods in VUR diagnosis. This study compared characteristics associated with VUR specific images and categorized patients according to a particular VUR grade. The study included 183 children. VUR was detected in 38.9% of patients, mean age 1.7±1.1 years. Grade II VUR was most common (60.3%), followed by grade III (29.4%). Study results showed that VUR occurred irrespective of age, gender, previous ultrasound findings, causative agent, and severity of urinary tract infection (UTI). VUR was more common in children with recurrent UTI. In the group of children with the first UTI not caused by Escherichia coli or with recurrent UTI, boys more commonly suffered from severe VUR (grade IV-V; 66.7%), while girls suffered from moderate VUR (grade II-III; 100%). In this study, the incidence of VUR in prenatally diagnosed hydronephrosis was 28.6%. It is necessary to develop an algorithm for the treatment of children after UTI in Croatia, which should include ceVUS. All children with possible VUR should be referred to a specialized center where it is possible to perform ceVUS.

CONTINUOUS GLUCOSE MONITORING AND TYPE 1 DIABETES MELLITUS CONTROL IN CHILD, ADOLESCENT AND YOUNG ADULT POPULATION - ARGUMENTS FOR ITS USE AND EFFECTS.

Sensors for continuous glucose monitoring (CGM) in intercellular fluid are used as a contemporary method to achieve better control in type 1 diabetes mellitus (DM), which is best shown through lower glycated hemoglobin (HbA1c) levels.The aim of this study was to assess how many of our patients used CGM (parents were solely financing all the cost of the device) and what was the effect of CGM on the control of DM. Data were retrospectively collected from medical records of patients actively treated at the Division of Endocrinology, Diabetology, Pulmonology and Allergology, Department of Pediatrics, Sestre milosrdnice University Hospital Center. The t-test was used for independent samples to compare the mean levels of HbA1c before and after the inclusion of CGM. CGM was used by 81 (32.1%) of our patients with type 1 DM, of which 43 met the inclusion criteria. The mean HbA1c level 6 months before the introduction of CGM was 8.2%±1.9 and after 12 months of CGM use it was 7.4%±1.2, which was a statistically significant improvement (p=0.026). Furthermore, our results demonstrated that the greatest improvement in HbA1c level was recorded in the groups of young adults (18-25 years) and youngest children (<12 years). We confirmed the efficacy of CGM in achieving better control of type 1 DM by significantly improving HbA1c levels in a population of highly motivated patients.
