Bacteremia and sepsis are common causes of morbidity and mortality worldwide, with incorrect or delayed diagnoses being associated with increased mortality. New tests or markers that allow a more rapid and less costly detection of bacteremia and sepsis have been investigated. The aim of this study was to clarify the cutoff value of the neutrophillymphocyte ratio (NLR) according to procalcitonin (PCT) level in the decision-making processes for bacteremia and sepsis. In addition, other white blood cell subgroup parameters, which are assessed in all hospitals, for bacteremia and sepsis were explored. This retrospective study included 1,468 patients with suspected bacteremia and sepsis. Patients were grouped according to the following PCT criteria: levels <0.05 ng/ml (healthy group), 0.05-0.5 ng/ml (local infection group), 0.5-2 ng/ml (systemic infection group), 2-10 ng/ml (sepsis group), and >10 ng/ml (sepsis shock group). One important finding of this study, which will serve as a baseline to measure future progress, is the presence of many gaps in the information on pathogens that constitute a major health risk. In addition, clinical decisions are generally not coordinated, compromising the ability to assess and monitor a situation. This report represents the first study to determine the limits of the use of NLR in the diagnosis of infection or sepsis using a cutoff value of <5 when sufficient exclusion criteria are used.

Purpose. This study aimed to investigate the autoimmune basis of idiopathic granulomatous mastitis (IGM) by determining the anti-nuclear antibody (ANA) and extractable nuclear antigen (ENA) levels of patients diagnosed with IGM. Material and Methods. Twenty-six IGM patients were evaluated. Serum samples were analyzed for autoantibodies by indirect immunofluorescence (IIF) using a substrate kit that induced fluorescein-conjugated goat antibodies to human immunoglobulin G (IgG). IIF patterns were read at serum dilutions of 1 : 40 and 1 : 100 for ANA positivity. Using the immunoblot technique, the sera of patients were assayed at dilutions of 1 : 40 and 1 : 100 for human autoantibodies of the IgG class to 15 lines of highly purified ENAs. Results. In the IIF studies for ANA, positivity was identified for four different patterns in the 1 : 40 diluted preparations, for three different patients in the 1 : 100 diluted preparations and only one pattern was identified at the 1 : 320 dilution. In the ENA studies, positivity was identified for four different pattern in the 1 : 40 dilution, and only one pattern was identified at the 1 : 100 dilution. Conclusion. This study was not able to support the eventual existence of an autoimmune basis for IGM.

We found that the MPV value may serve as a marker of the absence of acute-phase disease, and the NLR level as a marker of the presence of such disease, in patients with RA. More detailed analysis of disease activity is required to further explain the associations of the markers described above with disease activity.

Escherichia coli is the most frequently isolated microorganism from both community-acquired and nosocomial urinary tract infections in Turkey. A large number of studies concerning antibiotic susceptibility of E.coli have been published from different centers throughout the country. The aim of this study was to evaluate the antibiotic resistance patterns of E.coli strains isolated from urine cultures by a meta-analysis in published medical literature between the years of 1996-2012 in Turkey. The study was planned and conducted in accordance with the declaration of PRISMA and describes the methods of literature search, the determining criteria for inclusion and evaluation of articles, data collection and statistical analysis. To find the published series Google Scholar and PubMed international databases were used to access published manuscripts evaluated according to the determined criteria for acceptance and rejection. For each study, general data and antibiotic resistance rates were collected as a common unit. Publications considered as lacking in appropriate content was eliminated from the study. Statistical analysis of the data obtained were 95% confidence intervals, and p≤ 0.05 value was considered as significant difference. A total of 228 articles were found to be published during 1996-2012 period, while 101 of them were included in the meta-analysis according to the eligibility criteria. The analyses indicated that nitrofurantoin and piperacillin resistance rates have been decreased, whereas ciprofloxacin, cefepime, co-trimoxazole and extended-spectrum beta-lactamase (ESBL) positivity rates have been increased during the study period. The increases in the rates of ciprofloxacin and cefepime resistance and and ESBL production were statistically-significant (p< 0.05). A significant reduction in resistance rates for ampicilin, amoxicillin-clavulanate, and amikacin was noted in pediatric patients between 2002-2012. Ceftriaxone, imipenem, gentamicin and amikacin resistance were not homogenous between the geographical regions, and statistically significant differences were observed for amoxicillin-clavulanate, cefuroxime and ciprofloxacin resistance rates (p< 0.05). Antibiotic resistance rates, except for imipenem, in bacterial strains, isolated from hospitalized patients were found significantly higher in strains obtained from outpatients. The differences between those groups were significant in terms of ampicilin, amoxicillin-clavulanate, cefuroxime, ceftriaxone, trimethoprim-sulfamethoxazole, gentamicin, ciprofloxacin, amikacin and cefepime resistances (p< 0.05). It has been noted that antibiotic resistance patterns of E.coli strains isolated from urine cultures between 1996-2012 demonstrated significant variability, and many studies were based only on laboratory data. The results of this meta-analysis demonstrated that the resistance rates in commonly-used antibiotics for empirical therapy were high. In conclusion, information obtained by systematic evaluation of national data will be valuable for the determin...

This first assessment of this study is that nearly one third of the 4-6 age group healthy children population present nasal carriage of S. aureus in Turkey. However, it also shows that the rate of MRSA carriage remains low. In addition, it is considered that MRSA colonization may be a risk factor for healthcare workers' children.
