    Antimicrobial surgical prophylaxis: Still an issue in paediatrics

    No full text
    Objectives: Antimicrobial prophylaxis (AP) is an important means of reducing surgical site infections. The goal of this study was to evaluate the perioperative AP in paediatric practice and its compliance with surgical prophylaxis guidelines. Methods: A prospective study was conducted at Gazi University Faculty of Medicine, between September 2015 and April 2016. Paediatric patients who underwent surgical procedures were included in the study. Surgical AP was evaluated. Results: During the entire study period, 466 children underwent surgery at our centre; 433 (92.7\%) received antimicrobial prophylaxis. Overall adherence to the guidelines regarding surgical prophylaxis was 22.1\%. The rate of administration of surgical prophylaxis was significantly lower, and the duration was shorter when the surgical procedure was clean (P = 0.002). When the duration of the procedure was longer, the rate of administration of prophylaxis was higher (P = 0.000). The duration of postoperative prophylaxis was longer than recommended in 72.2\% of the patients. In the multivariate analysis, application errors increased with longer surgical time (P = 0.01, OR 2.18, 95\% CI 1.19-4.03). Conclusions: High rates of misapplication of antimicrobial surgical prophylaxis were observed in this study. Awareness and usage of guidelines should be encouraged. The education of clinicians should be supported by studies regarding surgical prophylaxis in children. (C) 2020 The Authors.

    In this study, hydroxyapatite material was prepared for the removal of Remazol N.Blue RGB (RB203) from waters. In the synthesis of hydroxyapatite material, waste hen's eggshell was evaluated as calcium source. Synthesis of hydroxyapatites was performed at three different pH values (pH 9, 10 and 11) using precipitation method. Before and after calcination of eggshells, XRF, XRD and SEM analysis were carried out. Synthesized hydroxyapatites were characterized by TGA-DTA, XRD and FTIR analysis. At the end of the characterization studies, hydroxyapatite structure was obtained better in pH 10 medium, and adsorption studies were carried out with the material prepared at this pH value. The effects of pH (2-12), amount of sorbent (2-10 g/L) and concentration of dye (25-200 mg/L) on adsorption of RB203 using hydroxyapatite were examined. In order to determine the mechanism of adsorption, the Langmuir, Freundlich, Temkin and Henry isoterm equations were used. Comparing the adsorption isotherms in terms of correlation coefficients (R-2), it was seen that the Langmuir, Freundlich and Temkin isotherm models were in good agreement with the experimental data. The highest adsorption capacity obtained with the Langmuir isotherm model was 27.93 mg/g. In order to examine the adsorption kinetics, the pseudo-first and the second order kinetic equations were used. The results of adsorption kinetics show that the adsorption of RB203 with hydroxyapatite was better expressed by the pseudo-second order kinetic equation. This study shows that the hydroxyapatite synthesized from waste calcined eggshell is a promising sorbent for adsorption of dye
