    Healthcare-associated staphylococcus aureus infections in children in Turkey: A six-year retrospective, single-center study

    Objective: To describe clinical and epidemiological characteristics, antimicrobial susceptibility and mortality-associated factors of healthcare-associated infections (HCAIs) caused by Staphylococcus (S.) aureus in children. Methods: We conducted a retrospective, single-centre study of pediatric HCAIs caused by S. aureus from a tertiary care hospital in Turkey between February 2014 and December 2019. The clinical and epidemiological characteristics and antimicrobial susceptibility of the methicillin-susceptible and methicillin-resistant S. aureus (MSSA and MRSA) isolates was evaluated. Results: A total of 310 pediatric patients were examined. Overall, 225 (72.6%) isolates were MSSA and 85 (27.4%) were MRSA. All S. aureus isolates were susceptible to teicoplanin, vancomycin, linezolid, tigecycline, mupirocin, and daptomycin. Penicillin resistance rates were high (89.0%), while fosfomycin, gentamicin, and clindamycin resistance rates were low (1.3%, 1.0%, and 2.3%, respectively). Except susceptibility to fosfomycin, which was significantly lower in 2014 compared to 2018 and 2019, no significant difference was found in the antimicrobial susceptibility of S. aureus isolates between the years. Baseline characteristics and mortality rate were similar comparing MRSA and MSSA causing HCAIs. The mortality rate of HCAIs caused by S. aureus was 6.5% (20 patients). Malignancy was an independent risk factor associated with mortality in the multivariate analysis (OR 5.446, 95% CI 1.573- 18.849). Conclusions: Our findings demonstrate that MSSA remained the most causative agent of HCAIs caused by S. aureus. The mortality rate was 6.5%, the antibiotic resistance rate was quite high for penicillin and diagnosis of malignancy was the main risk factor for increasing mortality in children. These findings could help improve the management of HCAIs caused by S. aureus in children.

    Microbiology of sinusitis and the predictive value of throat culture for the aetiology of sinusitis
    (ELSEVIER SCI LTD, 2005-05) ÜLGER, NURVER; Ilki, A; Ulger, N; Inanli, S; Ozer, E; Arikan, C; Bakir, M; Soyletir, G
    A prospective study of throat cultures and maxillary sinus aspirates from children with chronic sinusitis (n = 21), acute sinusitis (n = 28) or a clinical diagnosis of chronic adenoiditis (n = 41) was performed. Seventy-two bacterial pathogens were isolated from sinus aspirates from 52% of the study population. Haemophilus influenzae was most common pathogen, followed by Moraxella catarrhalis, Streptococcus pneumoniae, Staphylococcus aureus, and group A streptococci. Quantitative throat cultures had positive predictive values of 41%, 53% and 75% for H. influenzae, Strep. pneumoniae and M. catarrhalis, respectively, while negative predictive values were 93-98%, indicating that these three pathogens do not cause sinusitis when absent from the throat.
