Retrospective evaluation of "Rods and Rings" pattern detected in the anti-nuclear antibody (ANA) indirect immunofluorescence (IIF) test.

Introduction: Anti-rods and rings (anti-RR) antibodies have recently been described as a cytoplasmic pattern in IIF-based screening of autoantibodies on HEp-2 cells and ICAP has named it as AC-23. It is most frequently related to drug-induced antibody generation. This study aimed to investigate the clinical significance of AC-23 positivity and its relevance to the diagnosis and/or follow-up of the associated diseases and/or drug use.

High rate of colistin and fosfomycin resistance among carbapenemase-producing Enterobacteriaceae in Turkey.

When the problem with carbapenem-resistant Enterobacteriaceae (CRE) increases, the older antimicrobial agents such as colistin and fosfomycin are used for the treatment of these infections. In this study, the broth microdilution method for colistin and the agar dilution method for fosfomycin were used for a total of 147 multidrug-resistant (MDR) or extensively drug-resistant (XDR) strains of CRE. The study included Klebsiella pneumoniae (91.

Identification and molecular epidemiology of dermatophyte isolates by repetitive-sequence-PCR-based DNA fingerprinting using the DiversiLab system in Turkey.

Dermatophyte species, isolation and identification in clinical samples are still difficult and take a long time. The identification and molecular epidemiology of dermatophytes commonly isolated in a clinical laboratory in Turkey by repetitive sequence-based PCR (rep-PCR) were assessed by comparing the results with those of reference identification. A total of 44 dermatophytes isolated from various clinical specimens of 20 patients with superficial mycoses in Kayseri and 24 patients in Hatay were studied.

Evaluation of chromogenic agar, [corrected] VITEK2 YST and VITEK® MS for identification of Candida strains isolated from blood cultures.

The aim of this study is to compare conventional methods, chromogenic agar, [corrected] VITEK2 YST card and VITEK®MS system for the identification of Candida strains isolated from blood cultures. Fifty-four strains were identified according to conventional methods, chromogenic agar, [corrected] VITEK2 YST card and VITEK®MS. Sequencing was used as the reference method.

Diagnostic Accuracy of a New Urinalysis System, DongJiu, for Diagnosis of Urinary Tract Infection.

Objective: The microscopic and chemical analysis of urine is essential for the diagnosis of patients with urinary tract infections (UTI). Quantitative urine culture is the 'gold standard' method for the diagnosis of UTI, but it is labour-intensive and time consuming. The DongJiu 8602 is a new automated urinalysis system with dipstick and microscopy testing.

Evaluation of the Abbott Real Time HCV genotype II assay for Hepatitis C virus genotyping.

Objective: The determination of HCV genotypes and subtypes is very important for the selection of antiviral therapy and epidemiological studies. The aim of this study was to evaluate the performance of Abbott Real Time HCV Genotype II assay in HCV genotyping of HCV infected patients in Kayseri, Turkey.

Methods: One hundred patients with chronic hepatitis C admitted to our hospital were evaluated between June 2012 and December 2012, HCV RNA levels were determined by the COBAS® AmpliPrep/COBAS® TaqMan® 48 HCV test.

Is rapid antibacterial susceptibility testing medium reliable for routine laboratory practices?

Objective: Early detection of antibiotic susceptibility profile of the isolates has critical importance in terms of immediate beginning of the appropriate treatment and increasing of treatment success, such as meningitis, bacteriemia and sepsis. In the present study, it was aimed to compare the antibiotic susceptibility results of Quicolor (Salubris Inc., Massachusetts, USA) and standard disk diffusion method.

The Investigation of HCV RNA in Tear Fluid and Aqueous Humor in Patients with Anti-HCV Antibody Positive Who Underwent Cataract Surgery.

Purpose: To obtain aqueous humor and tear fluid samples during cataract surgery of the hepatitis C virus (HCV)-antibody-positive patients in order to analyze them for HCV RNA and compare these measurements with serum HCV RNA levels.

Methods: Twenty-nine anti-HCV-positive patients were included this study. HCV RNA viral load levels were determined by commercial real-time polymerase chain reaction system.

Interdigital foot infections: Corynebacterium minutissimum and agents of superficial mycoses.

Interdigital foot infections are mostly caused initially by dermatophytes, yeasts and less frequently by bacteria. Erythrasma caused by Corynebacterium minutissimum can be confused with superficial mycoses. The aim of the study was to determine the prevalence of the etiologic agents of superficial mycoses and the frequency of Corynebacterium minutissimum in interdigital foot infections.

Cutoff values for bacteria and leukocytes for urine sediment analyzer FUS200 in culture-positive urinary-tract infections.

Objectives: The microscopic analysis of urine is essential for the diagnosis of patients with urinary tract infections. Quantitative urine culture is the 'gold standard' method for definitive diagnosis of urinary-tract infections, but it is labor-intensive, time consuming, and does not provide the same-day results. The aim of this study was to evaluate the analytical and diagnostic performance of the FUS200 (Changchun Dirui Industry, China), a new urine sedimentation analyzer in comparison to urine culture as the reference method.

Distribution of hepatitis C virus genotypes in Kayseri region, in Turkey: unexpected rate of genotype 4.

Background: Hepatitis C virus (HCV) is an important cause of chronic liver disease. There are six genotypes and more than 80 subtypes of HCV. The aim of this study was to investigate the distribution of HCV genotypes in Middle Anatolia in Turkey, and the association of HCV genotypes with pre-treatment HCV RNA viral load, serum transaminase levels, and histopathological grade of liver fibrosis.

Clonal diversity and high prevalence of OXA-58 among Acinetobacter baumannii isolates from blood cultures in a tertiary care centre in Turkey.

Genotypic diversity, antimicrobial susceptibilty, and presence of OXA-genes were assessed in 100 nosocomial Acinetobacter strains from a tertiary-care hospital, Turkey. Ninety-eight isolates were identified by AFLP library identification to Acinetobacter baumannii. Furthermore, the isolates were divided into 30 AFLP clusters and single strains at a similarity cut-off level of 90%, the defined strain level.

Factors influencing survival in patients with multi-drug-resistant Acinetobacter bacteraemia.

Objectives: The incidence of multi-drug-resistant (MDR) Acinetobacter strains is increasing and therapeutic options are limited. However, controversy exists regarding the mortality attributable to antimicrobial resistance. The aim of this study was to analyse the clinical features and outcomes of patients with MDR Acinetobacter calcoaceticus-Acinetobacter baumannii complex (Acb complex) bacteraemia and determine the factors influencing survival by using 14-day mortality as the main outcome measure.
