    Aim: Zygomycosis is a severe angioinvasive infection caused by Zygomycetes. We retrospectively investigated 16 cases of zygomycosis. Materials and methods: The data of patients, who had been followed between 2004 and 2010 in 8 tertiary-care teaching hospitals, were reviewed. Demographic characteristics, underlying diseases, and clinical signs and symptoms of the patients, as well as diagnostic methods, data obtained by radiological imaging methods, and the therapies, were recorded. Therapeutic approaches, antifungal agents and duration of use, and the characteristics of the cases were identified. Results: The study included 11 female and 5 male subjects. The most common symptoms and clinical signs were fever (n = 9) and retro-orbital pain (n = 7). Rhinocerebral zygomycosis was the most common form. The mean time elapsed for diagnosis was 14.26 ± 13.96 (range: 2-52) days. Antifungal therapy was given to 15 patients (94%). In addition to antifungal therapy, 12 patients underwent surgical intervention 1 to 4 times. The mean duration of receiving antifungal therapy was 61.4 ± 58.02 (range: 1-180) days. The median duration of treatment was 62.5 (range: 42-180) days in survivors. Conclusion: Zygomycosis is an infectious disease with high mortality despite antifungal therapy and surgical interventions. © TÜBİTAK.

    Background/aim: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics. Materials and methods: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician. Results: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had ≤5 years of occupational experience (junior specialists = JSs) and 942 (49.4%) of them were physicians. Specialists having >5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05). Conclusion: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did. © TÜBITAK.

    Colistin efficacy in the treatment of multidrug-resistant and extremely drug-resistant gram-negative bacterial infections
    (Turkiye Klinikleri Journal of Medical Sciences, 2016) Çetin Ç.B.; Özer Türk D.; Şenol Ş.; Dinç Horasan G.; Tünger Ö.
    Background/aim: Colistin is used as a salvage therapy for multidrug-resistant and extremely drug-resistant gram-negative bacterial infections. Our aim was to evaluate colistin efficiency and toxicity in the treatment of these resistant gram-negative bacterial infections. Materials and methods: This is a retrospective study carried out in a tertiary care hospital during 2011–2013. Study data were collected from the medical records and consultations of the infectious diseases clinic. Results: The study group included 158 patients with nosocomial infections and 136 (86.1%) of them were hospitalized in the ICU. Respiratory tract infections were the most commonly observed ones (n = 103, 65.2%). The most frequently isolated microorganism was Acinetobacter baumannii (72.2%). A total of 98 (62.0%) patients had clinical cure. There was no statistically significant difference between monotherapy (n = 3/6, 50.0%) and combination therapies (n = 95/152, 62.5%) according to clinical response. Underlying ultimately fatal disease, previous renal disease, and total parenteral nutrition were independent risk factors for poor clinical response. Nephrotoxicity developed in 80 (50.6%) patients and clinical cure was statistically unrelated with nephrotoxicity. Conclusion: Colistin may be used as an effective agent for multidrug-resistant and extremely drug-resistant gram-negative bacterial infections with close monitoring of renal functions, especially for older and critically ill patients. © TÜBİTAK.

    Community-acquired pneumonia: Importance of molecular methods for etiological diagnosis and clinical features; [Toplumda gelişen pnömoni: Etyolojik tanıda moleküler yöntemlerin önemi ve klinik özellikler]
    (AVES İbrahim KARA, 2018) Özer-Türk D.; Tünger Ö.; Şakar-Coşkun A.; Gazi H.; Şanlıdağ T.; Kurhan F.; Çetin Ç.B.; Şenol Ş.
    Objective: This study aims to make an early identification for the diagnosis of community-acquired pneumonia (CAP), to increase the rate of etiological diagnosis and to distinguish bacterial and viral pathogens with the use of multiplex polymerase chain reaction (PCR) in addition to conventional methods, and to compare cases in the light of clinical and laboratory results. Methods: Ninety two CAP patients who were hospitalized and followed at our hospital between January-November 2013 were included in this study. Conventional culture and multiplex PCR were used to identify the causative microorganisms in the respiratory tract samples of the patients. Demographic data, risk factors, clinical, radiological and laboratory results, treatment and follow-up results of the cases were recorded. Statistical Package for the Social Sciences (SPSS) for Windows. Version 15.0 (SPSS Inc., Chicago, IL, USA) program was used in the analysis of the data. Results: CURB-65 score was determined ≥2 in 80.4% of the cases and 14.1% was followed in the intensive care unit. Of the patients, 42 (45.7%) were found to have bacterial and 20 (21.7%) were found to have viral agents while in 30 (32.6%) patients an agent could not be demostrated. Bacterial etiology was detected with conventional culture methods in 15 (16.3%) and with multiplex PCR in 42 (45.6%) cases. The difference between them was found to be statistically significant (p<0.001). It was found out that mostly bacterial factors were responsible for the CAP cases which were seen in fall or winter, and the etiology of the cases which were seen in spring and summer could not be determined in general (p<0.05). Variables such as sputum production, sore throat, auscultation findings and corticosteroid use were found to be statistically significant among bacterial, viral and unidentified etiology groups. Conclusions: It was demonstrated that molecular methods are beneficial for the early diagnosis of CAP. It was also thought that early diagnosis of viral etiology can prevent the unnecessary use of antibiotics as well as contributing to the patient management. © 2018, AVES İbrahim KARA.
