Item Assessment of Stem Cell Transplant Eligibility in Recipients with Oral Foci of Infection: Appropriate Conditioning Regimens(2023) Boga, Can; Sisli, Selen Nihal; Bahar, Abdul Rasheed; Tamer, Yusuf; Kasar, Mutlu; Bascil, Sibel; Ozdogu, Hakan; Asma, Suheyl; Demiroglu, Yusuf Ziya; Yeral, Mahmut; 0000-0002-0225-2477; 37341460; ADG-7352-2022Objectives: It is unclear whether patients with oral foci of infection should be approved for hematopoietic stem cell transplant with or without posttransplant cyclophosphamide. We compared the presence of oral foci of infection status on the effects of various conditioning regimens for such patients.Materials and Methods: Three groups were classified as autologous (carmustine-etoposide-cytarabinemelphalan, mitoxantrone-melphalan, and melphalan 200 mg/m2 groups; n = 502 patients), and 6 groups were classified as allogeneic (busulfan-fludarabinerabbit anti-T-lymphocyte globulin, busulfanfludarabine-posttransplant cyclophosphamide, fludarabine-cyclophosphamide-anti-T-lymphocyte globulin, busulfan-fludarabine-anti-T-lymphocyte globulin-posttransplant cyclophosphamide, total body irradiation-posttransplant cyclophosphamide, and other; n = 428 patients). Data were collected from a database that met international accreditation requirements. We evaluated dental radiological findings and calculated interobserver reliability.Results: Oral foci of infections increased febrile neutropenia and bacterial infection frequencies in both groups but only increased mucositis frequency in patients with allogeneic treatment. The frequencies of oral foci of infection-related complications were similar in both the autologous and allogeneic groups. Rate of graft-versus-host disease was not affected by oral foci of infection status. Periodontitis/cysts and periapical lesions increased the risk of infections at day 100 in the mitoxantrone-melphalan group versus the melphalan 200 mg/m2 group. We observed no differences among the autologous transplant groups in terms of early mortality. Similarly, no differences in early mortality were observed among the allogeneic groups.Conclusions: Transplant is a valid option in patients with oral foci of infections undergoing various autologous and allogeneic transplant protocols when time is of the essence, even at myeloablative dose intensities.Item Evaluation of 31 Cases with Urogenital Tuberculosis(2014) Kursun, Ebru; Turunc, Tahsin; Demiroglu, Yusuf Ziya; 0000-0002-7936-2172; 0000-0001-7956-7306; 0000-0002-9866-2197; ABD-4332-2020; AAG-5020-2020; GVT-0626-2022; AAZ-9711-2021Introduction: The present study evaluated the cases followed up and treated for urogenital tuberculosis in our hospital. Materials and Methods: Demographic and clinical characteristics, as well as laboratory data and treatment outcomes of 31 cases diagnosed as urogenital tuberculosis between January 2005 and January 2014 were retrospectively evaluated. Results: Of the 31 cases diagnosed with urogenital tuberculosis, nine (29%) had kidney, seven (22.5%) had bladder, nine (29%) had prostate, four (13%) had epididymis, and two (6.5%) had testicular involvement. History of contact with tuberculosis bacillus was present in five (16%) cases. Diabetes mellitus accompanied five (16%) and malignancy accompanied three (10%) cases. The most common complaints were dysuria (68%) and high fever (55%). Histopathological examination demonstrated tuberculosis bacillus in twenty cases (64.5%); whereas, Mycobacterium tuberculosis was isolated in the urine cultures of fifteen cases (48.4%) and acid-fast bacilli were detected in the urine samples of ten cases (32.3). It was determined that all cases had received quadruple anti-tuberculosis therapy for the first two months followed by dualanti-tuberculosis therapy for 4 to 10 months based on the site of involvement. One of the cases had undergone prostatectomy, one had undergone nephrectomy, one had undergone nephrectomy with ileocystoplasty in the same session, and one had undergone orchiectomy over the course of treatment with anti-tuberculosis drugs. It was determined that eight of the cases were lost on follow upafter anti-tuberculosis therapy was started and remaining cases recovered without complication. Conclusion: Tuberculosis is a chronic infectious disease that is difficult to diagnose and able to involve all systems and organs, and it remains important in developing countries like Turkey. We conclude that urogenital tuberculosis should be considered in patients with urogenital complaints that continuing for a long time period and do not respond to classical medical therapy.Item Evaluation of 28 Cases of Mucormycosis(2015) Kursun, Ebru; Turunc, Tuba; Demiroglu, Yusuf Ziya; Aliskan, Hikmet Eda; Arslan, Ayse Hande; 0000-0002-5708-7915; 0000-0001-9060-3195; 0000-0002-9866-2197; 0000-0001-7956-7306; 25590855; ABG-7034-2021; ADG-7352-2022; AAE-2282-2021; AAG-5020-2020; AAZ-9711-2021; GVT-0626-2022Mucormycosis is a rare but invasive fungal disease with high mortality. The present study aimed to retrospectively investigate the demographic characteristics, as well as the clinical, radiological and laboratory features and the results of treatment, in the patients followed in our hospital because of mucormycosis. The present study retrospectively evaluated 28 cases, which were followed in our hospital because of mucormycosis between January 2002 and July 2013. The clinical form was rhinocerebral in 27 cases (rhinoorbital in 12, nasal in 8 and rhinoorbitocerebral in 7) and disseminated in one case. With regard to predisposing factors, diabetes mellitus (n=20), haematological malignancy (n=6) and chronic renal insufficiency (n=5) were the leading concomitant diseases. Seventeen (61%) of 28 cases showed atypical clinical picture. With regard to the therapeutic outcomes; it was found that 14 (50%) cases died and six cases recovered with sequel. Today, when particularly the prevalence of immunosuppressive diseases and conditions are gradually increasing, the incidence of mucormycosis is also increased. Considering that the majority of our cases had atypical clinical involvement and complications, being familiar with the characteristics of this disease could be life-saving together with early diagnosis and treatment.Item Risk Factors for Occupational Brucellosis Among Veterinary Personnel in Turkey(2014) Kutlu, Murat; Ergonul, Onder; Sayin-Kutlu, Selda; Guven, Tumer; Ustun, Cemal; Alp-Cavus, Sema; Ozturk, Serife Baron; Acicbe, Ozlem; Akalin, Serife; Tekin, Recep; Tekin-Koruk, Suda; Demiroglu, Yusuf Ziya; Keskiner, Ramazan; Gonen, Ibak; Sapmaz-Karabag, Sevil; Bosnak, Vuslat; Kazak, Esra; https://orcid.org/0000-0002-9866-2197; 25132061; AAZ-9711-2021Veterinarians and veterinary technicians are at risk for occupational brucellosis. We described the risk factors of occupational brucellosis among veterinary personnel in Turkey. A multicenter retrospective survey was performed among veterinary personnel who were actively working in the field. Of 712 veterinary personnel, 84(11.8%) had occupational brucellosis. The median number of years since graduation was 7 (interquartile ranges [IQR], 4-11) years in the occupational brucellosis group, whereas this number was 9 (IQR, 4-16) years in the non-brucellosis group (p < 0.001). In multivariable analysis, working in the private sector (odds ratio [OR], 2.8; 95% confidence interval [95% CI], 1.55-5.28, p = 0.001), being male (OR, 4.5; 95% CI, 1.05-18.84, p = 0.041), number of performed deliveries (OR, 1.01; 95% CI, 1.002-1.02, p = 0.014), and injury during Brucella vaccine administration (OR, 5.4; 95% CI, 3.16-9.3, p < 0.001) were found to be risk factors for occupational brucellosis. We suggest that all veterinary personnel should be trained on brucellosis and the importance of using personal protective equipment in order to avoid this infection. (C) 2014 Elsevier B.V.

They are also important factors for increased morbidity and mortality. The aims of this study were to evaluate the number of urinary tract infections, to identify possible donor/receiver-based risk factors, and to evaluate the impact of these infections on graft function. Materials and Methods: Medical records of patients who had undergone kidney transplant between 2010 and 2017 were retrospectively analyzed. Results: Our study included 145 patients (49 women [33.8%] and 96 men [66.2%]), with mean age of 35.2 +/- 12.4 years. There were 105 episodes of urinary tract infections in 55 of 145 patients (37.9%) during the first year after transplant. Female sex (P = .001), glomerulonephritis as primary kidney disease (P = .04), pretransplant diabetes (P = .05), and presence of ureteral stent (P = .03) were significant risk factors for the development of urinary tract infections. The most frequent pathogens identified were Escherichia coli and Klebsiella pneumoniae. Mean glomerular filtration rate at 12 months was significantly lower in patients with urinary tract infection than in patients without infection (80 +/- 25 vs 68 +/- 28 mL/min; P = .006). Conclusions: In kidney transplant recipients, urinary tract infections are common complications and have negative outcomes on graft function. These infections remain an important disease that requires frequent investigations and new ways of approach for prevention.Item RISK FACTORS FOR URINARY TRACT INFECTION AFTER KIDNEY TRANSPLANTATION: A RETROSPECTIVE ANALYSIS(2019) Tekkarismaz, Nihan; Ozelsancak, Ruya; Micozkadioglu, Hasan; Caliskan, Kenan; Demiroglu, Yusuf Ziya; Haberal, Mehmet
