    Fungal sinusitis in immunocompromised hosts
    (2011-07-04T00:00:00Z) Apuhan, Tayfun; Kucukbayrak, Abdulkadir; Hakyemez, İSMAİL NECATİ; HAKYEMEZ, İSMAİL NECATİ
    The term -immunocompromised host- is generally applied to a variety of patients with various immune defects. Invasive rhinosinusitis is defined by the presence of local inflammation, with vascular and osseous necrosis with extensive soft tissue extension, and occurs almost exclusively in immunocompromised patients. Fungi have been increasingly recognized as important pathogens in severe acute and chronic sinusitis in immunosuppressed hosts. Earlier recognition of the disease, medical attention specific to the patient-s needs are required. After medical remission, significant complications of invasive fungal infection may be seen. Patients should be followed in the long-term, until remucosalization of the sinuses.

    Determining immunoassay cutoff value using Western blot results to predict hepatitis C infection in blood donors with low-titer anti-HCV reactivity
    (2013-07-01T00:00:00Z) Kucukbayrak, Abdulkadir; CAKMAK, Saadet; Hakyemez, Ismail Necati; Tas, Tekin; Akdeniz, Hayrettin; HAKYEMEZ, İSMAİL NECATİ
    Since the 1990s, blood donors have been scanned for anti-hepatitis C virus (anti-HCV) antibodies, which can be defined by enzyme immunoassay as a screening test. In this population, false-reactive ratios have been high. Recently, some authors have aimed to find a cutoff value for anti-HCV different from those established by test manufacturers to predict HCV infection. In this study, 321 patients, after two repeating tests, had reactive results in s/co 2.61 s/co, with 74.1 % sensitivity and 71.6 % specificity (area under the curve, 0.820; 95 % confidence interval, 0.753 to 0.887). We suggest that an effective cutoff value for anti-HCV other than that established by the manufacturer cannot be assigned to predict hepatitis C infection for blood donors in low-prevalence areas.

    Linezolid Versus Vancomycin for the Treatment of Methicillin-Resistant Staphylococcus aureus Keratitis in Rabbits
    (2013-07-01T00:00:00Z) Tas, Tekin; Kucukbayrak, Abdulkadir; Hakyemez, Ismail N.; Mengeloglu, Firat Z.; SIMAVLI, Huseyin; Ozyalvacli, Gulzade; Erdurmus, Mesut; HAKYEMEZ, İSMAİL NECATİ
    Purpose: To compare the efficacy of topical linezolid (LZD) 1 mg/mL or 2 mg/mL to vancomycin (VA) 50 mg/mL for the treatment of methicillin-resistant Staphylococcus aureus (MRSA) keratitis in rabbits.

    Nosocomial Acinetobacter baumannii infections and changing Antibiotic Resistance
    (2013-09-01T00:00:00Z) Hakyemez, Ismail Necati; Kucukbayrak, Abdulkadir; Tas, Tekin; Yikilgan, Aslihan Burcu; Akkaya, Akcan; Yasayacak, Aliye; Akdeniz, Hayrettin; HAKYEMEZ, İSMAİL NECATİ
    Objectives: In the intensive care setting, Acinetobacter baumannii causes ventilator-associated pneumonia and other nosocomial infections that are difficult to treat. Objective of this study was to investigate nosocomial A. baumannii infections and its changing antibiotic resistance.
