Stenotrophomonas maltophilia endophthalmitis following keratoplasty.

Endophthalmitis is among the most sight-threatening infections in ophthalmology practice. Many microorganisms causing endophthalmitis have been reported. Stenotrophomonas maltophilia is among the rare causes of endophthalmitis and has been reported after cataract surgery, intravitreal injections and ocular trauma.

Evaluation of the effects of Covid-19 on cochleovestibular system with audiovestibular tests.

Purpose: The purpose of the present study was to investigate the effects of COVID-19 on audiovestibular system with Transiently Evoked Distortion Otoacoustic Emissions (TOAE), Distortion Product Otoacoustic Emissions (DPOAE), video head impulse test (vHIT) and caloric test.

Methods: Audiovestibular findings of 24 patients with moderate/severe COVID-19 and 24 healthy controls were compared using pure tone audiometry, tympanometry, TOAE, DPOAE, caloric test, and vHIT.

Results: On audiometry, the pure tone averages of the COVID-19 patients were higher than the controls ( = .

[Investigation of the Relationship of Systemic Immune-Inflammation Index, C-Reactive Protein and Interleukin-6 with Viral Dynamics in Patients with COVID-19].

Coronaviruses are enveloped, positivepolarity, single-stranded RNA viruses that can cause respiratory and gastrointestinal tract infections, less likely to cause infections with hepatic, neurological and nephrotic involvement. A novel coronavirus termed as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) emerged in the city of Wuhan, China, and caused an outbreak of unusual viral pneumonia at the end of 2019. This study aimed to reveal the relationship between systemic immune-inflammation index (SII), C-reactive protein (CRP) and interleukin-6 (IL-6) and viral dynamics in COVID-19 patients.

Synthetic mesh placement in the presence of abdominal infection: An experimental study of feasibility.

Background: There are varying opinions on the feasibility of the placement of synthetic materials in contaminated surgical fields. The aim of this study was to investigate the outcomes of the use of a commercially available composite mesh in the presence of abdominal infection.

Methods: Twenty-four hours after the induction of experimental peritonitis, 20 rats were randomized into 2 groups of 10 subjects.

Role of efflux pump and OprD porin expression in carbapenem resistance of Pseudomonas aeruginosa clinical isolates.

Introduction: In recent years, the prevalence of multidrug-resistant P. aeruginosa has remarkably increased. Thus, we wanted to investigate the carbapenem resistance mechanisms and clonal relationship among 80 carbapenem-resistant P.

[Extended-spectrum beta-lactamase production by Enterobacteriaceae isolates from urine cultures of outpatients: results of a 7-year follow-up].

The aim of the study was to evaluate the change of the frequency of extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae isolates from urine samples of outpatients in years and to analyse the antibiotic resistance profiles for a rational drug use. The urine samples cultured in our laboratory from the patients who were admitted to outpatient clinics of our hospital between years 2007-2013 were included in this study. Enterobacteriaceae strains were isolated and identified by conventional methods and API 20E system (BioMérieux, France).

Molecular characterization of vancomycin-resistant Enterococcus faecium strains isolated from carriage and clinical samples in a tertiary hospital, Turkey.

This study aimed to determine the presence of vancomycin resistance (vanA and vanB) and virulence genes (esp, asa1, gelE, ace, hyl, cylA, cpd and ebpA) in vancomycin-resistant Enterococcus faecium (VREfm) strains and to analyse the clonal relationships among the strains. E. faecium strains were identified from rectal and clinical specimens by biochemical tests and the API-20 Strep kit.

[Detection of plasmid-mediated AmpC beta-lactamase production in Escherichia coli and Klebsiella spp. isolates].

This study was conducted to obtain data about prevalence of plasmid-mediated AmpC (pAmpC), efficacy of various phenotypic tests applied for the detection of pAmpC-mediated resistance and the enzyme types responsible for this resistance. A total of 1316 isolates (1030 Escherichia coli and 286 Klebsiella spp.) obtained from the clinical samples sent to our laboratory between 2008-2011 period, from various inpatient and outpatient clinics and intensive care units, were included in this study.

[Anti-HIV and confirmation test results of our hospital for seven years (2004-2010)].

In this study, 7-year anti-HIV test results of our medical microbiology laboratories were evaluated retrospectively. Between 2004 and 2010, a total of 268.901 blood samples from blood bank, outpatient and inpatient clinics of Ankara Ataturk Training and Research Hospital were tested for HIV antibodies by one of the following macro-ELISA systems [Vitros ECi (Ortochemical Diagnostik, USA), Axsym (Abbott, USA) and Architect (Abbott, USA)] in different periods.

[Antibiotic resistance profiles of Acinetobacter species isolated from several clinical samples between 2007-2010].

This study was aimed to investigate the changes in antibiotic resistance profiles of Acinetobacter spp. in our hospital during a four-year period. The study included a total of 465 non-duplicate Acinetobacter spp.

[In vitro susceptibility of methicillin-resistant Staphylococcus aureus isolates to vancomycin, teicoplanin, linezolide and daptomycin].

In this study, vancomycin, teicoplanin, linezolide and daptomycin susceptibility rates of 67 methicillin-resistant Staphylococcus aureus (MRSA) isolates obtained from various clinical samples between November 2006 and August 2010 in our laboratories, were investigated by E-test method and MIC values of the drugs were determined. Seventeen (25%) of the samples were from outpatient wards, 50 (75%) from inpatients of which 24 (48%) were from intensive care units. Distribution of MRSA isolated clinical samples were as follows: 16 (23.
