    In vitro evaluation of E. coli and S. epidermidis adhesion on dressing materials used in hypospadias repair
    (Springer Verlag, 2014) Soyer T.; Bostanoğlu E.; Aslan M.K.; Boybeyi O.; Demirbilek M.; Göçmen J.S.
    Background: An in vitro study was performed to evaluate the adherence of Escherichia coli and Staphylococcus epidermidis to different dressing materials. Methods: Hydrophyl gauze swab (GS), sterile flax swab (FS), and their nitrofurazone (Furacin®) absorbed forms (GSF and FSF), sterile paraffin-covered gauze with chlorhexidine acetate (0.5 %) (Bactigrass®, BG), and semipermeable transparent film gauze (Tegaderm®, TG) were used in the study. A 1 cm 2 of each material was placed in culture plates, and E. coli ATCC 25922 and S. epidermidis ATCC 12228 were suspended in each plate. After 24, 48 h, and 1 week of incubation period, colony counts were calculated in colony-forming units (CFU) per square centimeter unit. Bacterial adhesion was compared between groups, and each dressing material was also compared for different incubation periods (24, 48 h, and 1 week). Results: The colony counts were significantly decreased in GSF and FSF groups (Kruskal-Wallis test, p < 0.05). There was no difference for E. coli adhesion in GS, FS, BG, and TG groups (p > 0.05). The significant difference detected for S. epidermidis adhesion in the first 24 to 48 h could not be detected at the end of a 1-week period. There was no statistical difference in groups when compared for 24-, 48-h, and 1-week periods of incubations (Wilcoxon signed-rank test, p > 0.05). In BG group, E. coli adhesion was increased, and S. epidermidis adhesion was decreased without a significant difference at the end of a 1-week period (p > 0.05). Conclusions: Nitrofurazone absorbed sterile gauze materials have less bacterial adhesion. In vitro adhesion of E. coli and S. epidermidis did not differ between the 24-h and 1-week period. E. coli adhesion to BG can be increased if the duration of dressing prolonged up to a 1-week period.Level of Evidence: Not ratable. © 2013 Springer-Verlag Berlin Heidelberg.

    Serum procalcitonin level in monitorization of surgical site infections in neonates
    (Ondokuz Mayis Universitesi, 2016) Boybeyi O.; Soyer T.; Akbas O.T.; Guzoglu N.; Aslan M.K.; Gunal Y.D.; Aliefendioglu D.
    A retrospective study was performed to evaluate the role of white blood cell (WBC), C-reactive protein (CRP) and procalcitonin (PCT) levels in the follow-up and treatment of surgical site infections (SSI) in neonates. Neonates who underwent surgical intervention (n: 34) were evaluated for gestational age, sex, diagnosis, inflammatory markers (WBC, CRP, PCT), clinical findings, results of cultures and response to antimicrobial treatment. Records of 34 neonates and 36 surgical interventions were included to the study. Twenty (58.8%) of patients had SSI. Postoperatively CRP, WBC and PCT levels were increased (77%, 77%, 77% respectively) in patients with SSI. Postoperatively CRP, and WBC levels were increased (57% and 64% respectively) in patients without SSI. In conclusion, CRP levels and WBC count were significantly increased in 77% of cases after surgery. Increased PCT levels were detected only in patients with SSI. PCT levels may be considered as the most valuable marker to monitor SSI in neonates after surgery. © 2016 OMU.
