    Multiple Brain Abscesses Due to Phialemonium in a Renal Transplant Recipient: First Case Report in the Literature
    (2015) Aydin, Mehtap; Ozcelik, Umit; Cevik, Halime; Cinar, Ozlem; Evren, Ebru; Demirag, Alp; 0000-0003-1073-2494; 0000-0003-4044-9366; 26640919; AAG-8651-2021; HLX-0937-2023; JAZ-1759-2023
    Fungal brain abscesses are a rare but serious complication in transplant recipients. Phialemonium organisms are rare causes of invasive mold infections. Here, we present the first case of a renal transplant recipient with multiple brain abscesses caused by Phialemonium infection A. A 51-year-old female kidney transplant recipient was admitted with pneumonia of an unknown cause and treated with empiric intravenous antibiotics. Her treatment was uneventful, and she was discharged 1010 days later. After 5 days, she was readmitted with fever, cerebral palsy, and speech disorder. The patient had undergone living-donor renal transplant 7 months earlier. A cranial computed tomography and magnetic resonance imaging were performed for a possible cerebro vascular pathology. The magnetic resonance imaging scan showed multiple brain abscesses located at the left parietal, frontal and occipital lobes; right parietal and occipital lobes; right basal ganglia; and left cerebellum. The patient received meropenem, linezolid, sulfamethoxazole and trimethoprim, and AmBisome for probable pathogenic infection, and immunosuppressive agents dosage was reduced increasingly immuno suppressed. We identified Phialemonium in cerebrospinal fluid culture. The patient received voriconazole 200 mg twice daily. Lesions could not be drained due to lack of capsula formation. The patient died on the 30th day of antifungal therapy. Phialemonium organisms, although a rare cause of fungal infections, are associated with a high mortality rate in immunocompromised patients. To our knowledge, this is the first case report in the literature describing multiple brain abscesses due to Phialemonium in a transplant recipient. Clinicians recipient should be alert about these rare opportunistic fungi in the differential diagnosis of brain abscess, and bronchoscopy and broncho alveolar lavage are recommended for transplant patients when they are admitted with pneumonia exclude fungal infections.

    Delaying Renal Transplant after Radical Prostatectomy for Low-Risk Prostate Cancer
    (2015) Ozcelik, Umit; Bircan, Huseyin Yuce; Karakayali, Feza; Moray, Gokhan; Demirag, Alp; 0000-0002-1874-947X; 0000-0003-1073-2494; 0000-0003-2498-7287; 26640918; AAB-3888-2021; AAG-8651-2021; AAE-1041-2021; R-6394-2019
    To minimize the recurrence of a previously treated neoplasm in organ recipients, a period of 2 to 5 years without recurrence is advocated for most malignancies. However, prostate cancer is different because of its biological properties, diagnosis, and treatment. Most prostate cancers are detected at a low stage and demonstrate slow growth after detection. Definitive treatment with radical prostatectomy affords excellent results. Renal transplant candidates with early-stage prostate cancer have a higher risk of dying on dialysis than dying from prostate cancer; therefore, renal transplant candidates with organ-confined prostate cancer should be immediately considered for transplant.

    Development of an Information Model for Kidney Transplant Wait List
    (2015) Bircan, Huseyin Yuce; Ozcelik, Umit; Uysal, Nida; Demirag, Alp; Haberal, Mehmet; 0000-0003-1073-2494; 0000-0002-3462-7632; 26640914; R-6394-2019; AAG-8651-2021; AAJ-8097-2021
    Objectives: Deceased-donor kidney transplant is unique among surgical procedures that are an urgent procedure performed in an elective population. It has not been possible to accurately determine when a given patient will be called for transplant. Patients on the active transplant list can be called for a transplant at any time. As a result, every effort must be made to optimize their health according to best practices and published clinical practice guidelines. Materials and Methods: Once the patient is placed on the transplant wait list after undergoing an initial extensive evaluation, continued surveillance is required. Therefore, we developed a kidney transplant wait list surveillance software program that alerts organ transplant coordinator on time regarding which patients need a work-up. Results: The new designed software has a database of our waiting patients with their completed and pending controls. The software also has built-in functions to warn the responsible staff with an E-mail. If one of the controls of a recipient delayed, the software sends an automated E-mail to the staff regarding the patients delayed controls. The software is a Web application that works on any platform with a Web browser and Internet connection and allows access by multiple users. The software has been developed with NET platform. The database is SQL server. The software has the following functions: patient communication info, search, alert list, alert E-mail, control entry, and system management. Conclusions: As of January 2014, a total of 21 000 patients were registered on the National Kidney Transplant wait list in Turkey and the kidney transplant wait list had been expanding by 2000 to 3000 patients each year. Therefore computerized wait list programs are crucial to help to transplant centers to keep their patients up-to-date on time.
