    (BMC, 2021-12) GÜL, FETHİ; Bilgin, Huseyin; Gelmez, Gulsen Altinkanat; Bayrakdar, Fatma; Sayin, Elvan; Gul, Fethi; Pazar, Nazli; Culha, Gulcan; Yildiz, Serap Suzuk; Cinel, Ismail; Korten, Volkan
    Background: We report a nosocomial outbreak caused by Burkholderia cepacia that occurred among six patients admitted in the medical and surgical intensive care unit between 04 March 2019 and 02 April 2019 in Istanbul, Turkey. Methods: The outbreak investigation was launched on 11 March 2019 five days after the detection of B. cepacia in four different patients. We defined potential reservoirs and started environmental screening. We sampled the liquid solutions used in patient care activities. Pulse-field gel electrophoresis (PFGE) was performed to determine the genetic relatedness of environmental and patient samples. Results: Burkholderia cepacia was isolated in tracheal aspiration cultures of six patients. Three out of six patients developed healthcare-associated pneumoniae due to B. cepacia. Environmental cultures in the ICUs revealed B. cepacia growth in 2% chlorhexidine-gluconate mouthwash solution that been used in the colonized patients as well as in samples obtained from the unused products. PFGE revealed the patient and a specific batch of chlorhexidine mouthwash solution samples had a 96% similarity. Conclusion: Contamination of medical solutions used in critical patient care could cause outbreaks and should be detected early by infection control teams.

    Miliary Tuberculosis Induced Acute Liver Failure
    (HINDAWI LTD, 2015) BİLGİN, HÜSEYİN; Toptas, Tayfur; Ilhan, Birkan; Bilgin, Huseyin; Dincses, Elif; Ozdogan, Osman; Kaygusuz-Atagunduz, Isik; Odabasi, Zekaver; Korten, Volkan; Firatli-Tuglular, Tulin
    Hepatobiliary tuberculosis is uncommon even in endemic countries. It is associated with a high mortality and is even diagnosed early in the disease course. Acute liver failure (ALF) caused by tuberculosis bacilli has been reported in only a few reports. All previous cases have been diagnosed by postmortem examination. Time to antituberculosis treatment is very critical. In case of suggestive findings on clinical and radiologic examination, antituberculosis treatment should be initiated immediately. Drug use can be a challenge in patients with ALF. However, as long as the other possible causes of ALF can be excluded and hepatotoxic drugs were avoided during the early course of treatment, such a highly fatal presentation of tuberculosis can be treated safely. Here, we report a case of acute liver failure as a presentation of miliary tuberculosis. He was treated successfully with antituberculosis treatment.

    To describe the change in the epidemiology of health care-associated infections (HAI), resistance and predictors of fatality we conducted a nationwide study in 24 hospitals between 2015 and 2018. The 30-day fatality rate was 22% in 2015 and increased to 25% in 2018. In BSI, a significant increasing trend was observed for Candida and Enterococcus. The highest rate of 30-day fatality was detected among the patients with pneumonia (32%). In pneumonia, Pseudomonas infections increased in 2018. Colistin resistance increased and significantly associated with 30-day fatality in Pseudomonas infections. Among S. aureus methicillin, resistance increased from 31 to 41%.

    Successful treatment of an invasive fungal infection caused by Talaromyces sp. with voriconazole
    (ELSEVIER SCIENCE BV, 2015-06) BİLGİN, HÜSEYİN; Sili, Uluhan; Bilgin, Huseyin; Masania, Rikesh; Eryuksel, Emel; Cimsit, Nun I. Cagatay; Ayranci, Gulcicek; Richardson, Malcolm; Korten, Volkan
    Invasive fungal infections (lFl) are on the rise due to increasing numbers of immunosuppressed and critically ill patients. A malignant-looking pulmonary nodule in an immunosuppressed patient may indeed be caused by a fungal organism. We report a patient, who was eventually diagnosed with an IFI caused by an agent of hyalohyphomycosis, Talaromyces sp determined via molecular methods and succesfully treated with voriconazole.

    Sequential Measurements of Pentraxin 3 Serum Levels in Patients with Ventilator-Associated Pneumonia: A Nested Case-Control Study
    (HINDAWI LTD, 2018) BİLGİLİ, BELİZ; Bilgin, Huseyin; Haliloglu, Murat; Yaman, Ali; Ay, Pinar; Bilgili, Beliz; Arslantas, Mustafa Kemal; Ozdemir, Filiz Ture; Haklar, Goncagul; Cinel, Ismail; Mulazimoglu, Lutfiye
    Purpose. The main purpose of this study was to investigate the dynamics of pentraxin 3 (PTX3) compared with procalcitonin (PCT) and C-reactive protein (CRP) in patients with suspicion of ventilator-associated pneumonia (VAP). Materials and Methods. We designed a nested case-control study. This study was performed in the Surgical Intensive Care Unit of a tertiary care academic university and teaching hospital. Ninety-one adults who were mechanically ventilated for >48 hours were enrolled in the study. VAP diagnosis was established among 28 patients following the 2005 ATS/IDSA guidelines. Results. The median PTX3 plasma level was 2.66 ng/mL in VAP adults compared to 0.25 ng/mL in non-VAP adults (p < 0.05). Procalcitonin and CRP levels did not significantly differ. Pentraxin 3, with a 2.56 ng/mL breakpoint, had 85% sensitivity, 86% specificity, 75% positive predictive value, and 92.9% negative predictive value for VAP diagnosis (AUC = 0.78). Conclusions. With the suspicion of VAP, a pentraxin 3 plasma breakpoint of 2.56 ng/mL could contribute to the decision of whether to start antibiotics.

    Transmission of SARS-CoV-2 in Different Districts of a County in Istanbul, March to September 2020
    (SAGE PUBLICATIONS INC, 2021-07) TOPUZOĞLU, AHMET; Bilgin, Huseyin; Topuzoglu, Ahmet; Korten, Volkan
    Epidemics caused by airborne viruses in cities with large populations create a big problem as in the current COVID-19 pandemic. Cramped lifestyle, busy workplaces, crowded public transportation, and higher household member counts are responsible for the transmission of the disease. In Turkey, Istanbul has taken the lead in the number of cases since the beginning of the epidemic. The excess population density is the major cause for disease transmission. It is essential to monitor the contaminated regions with geographical information systems on city maps. Outbreak maps visualize and help analyze the patterns of transmission and serve as a communication and education tool. A dynamic heat map video of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) polymerase chain reaction positive cases in a county of Istanbul was generated. The heat map visualizes how the epidemic spread to all the districts and the cumulative cases increased in one county of Istanbul with real attack rates.

    The need for an antibiotic stewardship program in a hospital using a computerized pre-authorization system
    (ELSEVIER SCI LTD, 2019-05) ERTÜRK ŞENGEL, BUKET; Sengel, Buket Erturk; Bilgin, Huseyin; Bilgin, Beyza Oren; Gidener, Tolga; Saydam, Simge; Pekmezci, Aslihan; Ergonul, Onder; Korten, Volkan
    Objectives: Antimicrobial stewardship programs (ASPs) have an important role in the appropriate utilization of antibiotics. Some of the core strategies recommended for ASPs are pre-authorization and prospective audit and feedback. In Turkey, a unique nationwide antibiotic restriction program (NARP) has been in place since 2003. The aim of this study was to measure the effect of a prospective audit and feedback strategy system along with the NARP. Methods: A prospective quasi-experimental study was designed and implemented between March and June 2017. A computerized pre-authorization system was used as an ASP strategy to approve the antibiotics. During the baseline period, patients with intravenous (IV) antibiotic use >= 72 h were monitored without intervention. In the second period, feedback and treatment recommendations were given to attending physicians in the case of IV antibiotic use >= 72 h. The modified criteria of Kunin et al. and Gyssens et al. were followed for appropriateness of prescribing. Days of therapy (DOT) and length of stay (LOS) were calculated and compared between the two study periods. Results: A total of 866 antibiotic episodes among 519 patients were observed. A significant reduction in systemic antibiotic consumption was observed in the intervention period (575 vs. 349 DOT per 1000 patient-days; p < 0.001). On multivariate analysis, prospective audit and feedback (odds ratio 1.5, 95% confidence interval 1.09-2.04; p = 0.011) and pre-authorization of restricted antibiotics (odds ratio 1.7; 95% confidence interval 1.2-2.31; p = 0.002) were the predictors of appropriate antimicrobial use. Mean LOS was decreased by 2.9 days (p = 0.095). Conclusions: This study showed that the antimicrobial restriction program alone was effective, but the system should be supported by a tailored ASP, such as prospective audit and feedback.

    Hand hygiene knowledge, perception and practice of healthcare workers in a Turkish university hospital intensive care unit
    (J INFECTION DEVELOPING COUNTRIES, 2019-08-31) BİLGİN, HÜSEYİN; Sili, Uluhan; Ay, Pinar; Bilgin, Huseyin; Hidiroglu, Seyhan; Korten, Volkan
    Introduction: While improvement of hand hygiene (HH) compliance is considered as the best approach to reduce healthcare-associated infections, the instructional interventions in HH among healthcare workers of intensive care unit (ICU) of our hospital was not successful enough. The following study was conducted to evaluate HH knowledge, perception, practice and effectiveness of the trainings among healthcare workers of ICU in our hospital. Methodology: A cross-sectional study was conducted in the ICU containing 8 medical and 16 surgical beds with 284 filled questionnaires about HH knowledge and 1187 observed opportunities for HH compliance. Results: Overall observed HH compliance rate was 40.6%; lowest compliance was 21.7% for before clean/aseptic procedure indication and highest compliance was 68.6% for after touching a patient indication. Although > 90% healthcare workers correctly identified the World Health Organization's five indications for HH, 82 -85% failed to recognize non-indications, i.e. when it was not necessary to perform HH. Our study showed that 15.1% of healthcare workers neither received nor felt the need for HH training. Conclusions: Despite regular HH trainings, healthcare workers could not differentiate when HH was not required which suggested failure to understand HH rationale. This may explain poor HH compliance rates. A systematic study is needed in order to find out the reasons behind of this noncompliance and improve HH training methods for educating healthcare workers.

    Acute variceal bleeding is an important cause of mortality among cirrhotic patients. Endoscopic band ligation and medical vasoactive drugs are the main treatment options for actively bleeding varices. In some cases, these therapies can fail and a Sen-gstaken Blakemore tube (SBT) is used to stop the bleeding by direct compression of varices. Although it is very effective in stopping variceal bleeding, SBT has some lethal complications. In this paper, we discuss the case of a patient who developed esopha-geal perforation after insertion of the SBT.
