    Clinical aspects and risk factors of nosocomial Stenotrophomonas maltophilia bacteremia episodes in a Turkish intensive care unit
    (E.S.I.F.T. srl, 2007) Tunger O.; Vural S.; Cetin C.B.; Keles G.; Borand H.; Gazi H.
    Stenotrophomonas maltophilia is an important nosocomial pathogen with increasing frequency in recent years, especially in immunocompromised and clinically debilitated patients. The aim of this study is to describe the characteristics of 35 episodes of S. maltophilia bacteremia at Celal Bayar University hospital in Turkey over a 3-year period from January 2003 to December 2005. Cases were identified with microbiology laboratory records and clinical data were collected from the medical record of each patient. The source of bacteremia was central venous catheter (CVC) in 65.7% (23) and respiratory tract infection in 2.9% (1) of episodes while the source of bacteremia was unknown in 11 (31.4%) episodes of bacteremia. Factors significantly associated with mortality were age of ≥65 years, APACHE score of ≥16, the presence of the total parenteral nutrition, anemia, low creatinine clearance level and shock. The most sensitive antibiotic was found as trimethoprim-sulfamethoxazole (91.4%) in antibiotic susceptibility testing of the isolates. Susceptibilities of piperacillin-tazobactam and netilmicin which frequently used antibiotics as an empirical therapy were 62.8% and 68.6%, respectively. © E.S.I.F.T. srl.

    Rational antibiotic use
    (Journal of Infection in Developing Countries, 2009) Tunger O.; Karakaya Y.; Cetin C.B.; Dinc G.; Borand H.
    Background: Development of resistance to antimicrobial agents and increase of cost as the result of unnecessary and inappropriate use of antibiotics has become a global health problem. Therefore many strategies, which are aimed at optimizing antibiotic therapy, have been developed until now. In Turkey, an antibiotic restriction policy as a governmental solution was applied to decrease the antibiotic use and especially costs by Ministry of Health in 2003. The aim of this study is to evaluate the rational antibiotic use and the impact of the implementation of new restriction policy, with their reinforcement by infectious disease specialist, on the hospital wide use of antibiotics. Methodology: The data of the inpatients received antibiotics (n=495) during January-June 2006 were compared with our previous study performed by the same methodology before the restriction policy in 1998. In both studies, prospective active daily surveillance of patients was performed by three infectious disease specialists. The appropriateness of antibiotic therapy was determined using the criteria described by Kunin and Jones. The data were analyzed by using SPSS for Windows. Results: While the rate of antibiotic use decreased from 16.6% to 11.3%, rational use increased after the restriction policy (p<0.001). Besides the specific antibiotic use increasing, prophylactic antibiotic use was found decreased (p<0.001). Mostly determined irrationality was the prophylactic uses in both studies. As expected, infectious disease specialist examinations resulted in an increase in the appropriate antibiotic use. Conclusions: The restriction policy was effective in decreasing the antibiotic consumption and increasing the rational antibiotic prescription in our hospital. Copyright © 2008 Tunger et al.

    Brucellosis: A rare cause of febrile neutropenia in acute myeloblastic leukemia
    (2011) Ozbalci D.; Ergene U.; Cetin C.B.
    Brucellosis is a zoonotic disease and endemically seen in the Middle East, Eastern Europe and continental America. Febrile neutropenia related to Brucellosis has been reported only in a few cases. Brucella was cultured from the bone morrow of a 42-year-old woman who was admitted to hospital with symptoms of fever and fatigue and later diagnosed as acute myeloblastic leukemia (AML). The patient was treated for both AML and Brucellosis without any problems and discharged from the hospital after scheduling her follow-up visits. Brucellosis might be considered in the etiology of febrile neutropenia in endemic regions and must be treated effectively to prevent possible morbidity and mortality during or after chemotherapy. © 2010 Springer Science+Business Media, LLC.

    A rare parasitic infection: visceral leishmaniasis case after gastric cancer treatment
    (Springer-Verlag Wien, 2018) Yolcu A.; Dirican A.; Ozturk G.G.; Cetin C.B.; Aydogdu I.
    We present a case of Visceral Leishmaniasis (VL) in a patient with gastric cancer treated with chemoradiotherapy. A 69-year-old man with gastric carcinoma had been treated with total gastrectomy, lymphadenectomy and postoperative radiotherapy with chemotherapy. Then 3 years after treatment, due to pancytopenia with progressive trombocytopenia and splenomegaly, bone marrow examination was performed and Leishmania spp. amastigotes were diagnosed. When antibiotherapy was completed, splenomegaly was eliminated and the laboratory results became normal. VL should be kept in mind in the differential diagnosis of patients, even adults, with splenomegaly, trombocytopenia and a history of contact with dogs in endemic countries such as Turkey. © 2018, Springer-Verlag GmbH Austria, part of Springer Nature.
