    Peritoneal dialysis-related peritonitis with an unexpected micro-organism: enterococcus hirae
    (2017-01-01) BARUTÇU ATAŞ, DİLEK; AŞICIOĞLU, EBRU; VELİOĞLU, ARZU; TUĞLULAR, ZÜBEYDE SERHAN; ARIKAN, İZZET HAKKI; BARUTÇU ATAŞ D., AYKENT M. B., AŞICIOĞLU E., ARIKAN İ. H., VELİOĞLU A., TUĞLULAR Z. S., ÖZENER İ. Ç.
    Enterococcus Hirae is a gram-positive, facultative, anaerobic bacterium which is usually a zoonotic pathogen rarely isolated from human infections. There are no published reports describing continuous ambulatory peritoneal dialysis (CAPD) related- peritonitis with Enterococcus Hirae in the literature. With the following report, we describe the case of peritoneal dialysis (PD)-related peritonitis due to Enterococcus Hirae.

    Uncommon presentation of CAPD-related peritonitis with unusual organism: Kocuria kristinae. Case report and review of the literature
    (MARMARA UNIV, FAC MEDICINE, 2017-01-15) VELİOĞLU, ARZU; Barutcu Atas, Dilek; Arikan, Hakki; Aykent, Basar; Asicioglu, Ebru; Velioglu, Arzu; Tuglular, Serhan; Ozener, Cetin
    Kocuria kristinae is a gram-positive coccus of Micrococcaceae family. Kocuria kristinae inhabits the skin and mucous membranes. It can cause opportunistic infections in patients with indwelling devices and severe underlying diseases. We describe here a case of acute peritonitis caused by Kocuria kristinae in a patient on continuous ambulatory peritoneal dialysis (CAPD). Additionally, a review of other reported CAPD related peritonitis by Kocuria kristinae is provided. The importance of Kocuria kristinae as a pathogen in patients with CAPD peritonitis should not be underestimated.

    Role of Diffusion-weighted MR Imaging in the Differentiation of Benign Retroperitoneal Fibrosis from Malignant Neoplasm: Preliminary Study
    (RADIOLOGICAL SOC NORTH AMERICA, 2014-08) VELİOĞLU, ARZU; Bakir, Baris; Yilmaz, Fatma; Turkay, Rustu; Ozel, Sevda; Bilgic, Bilge; Velioglu, Arzu; Saka, Bulent; Salmaslioglu, Artur
    Purpose: To evaluate diffusion-weighted imaging (DWI) features and signal intensity values at T2-weighted magnetic resonance (MR) imaging for differential diagnosis of benign retroperitoneal fibrosis (RPF) and plaque-like retroperitoneal malignant neoplasms. Materials and Methods: Institutional review board approval and informed consent were obtained for this retrospective study. Fifty-one patients with plaque-like confluent retroperitoneal soft-tissue masses were divided into three groups: group I, 25 patients with malignant RPF and retroperitoneal malignant neoplasm; group II, 16 patients with chronic RPF; and group III, 10 patients with active RPF. On T1-weighted (unenhanced and contrast material-enhanced), T2-weighted, and DWI (b = 1000 sec/mm(2)) images, apparent diffusion coefficient (ADC) values and quotients of postcontrast signal intensities between lesions and psoas muscle were evaluated. The chi(2) test was used to compare categorical values; one-way analysis of variance and Kruskal-Wallis tests were used to compare groups. Results: Overall sensitivity, specificity, and positive and negative predictive values of DWI findings were 92% (23 of 25 patients), 62% (16 of 26 patients), 70% (23 of 33 patients), and 89% (16 of 18 patients), respectively. Mean ADC values were 0.79 +/- 0.19 in group I, 1.43 +/- 0.16 in group II, and 0.91 +/- 0.14 in group III. When comparing values, differences between groups I and II (ADC values, P < .0001; DWI quotients, P < .0001; postcontrast quotients, P = .001) and groups II and III (ADC values, P < .0001; DWI quotients, P = .016; postcontrast quotients, P = .04) were significant. There was no significant difference between groups I and III or between the three groups when T2-weighted values were compared. Conclusion: ADC of chronic RPF was higher than that for active RPF or malignant RPF and retroperitoneal malignant neoplasm. DWI can contribute to differential diagnosis of chronic RPF and malignant neoplasms with RPF morphology. Lesions in the malignant group and active RPF group had similar enhancement patterns, while those in the chronic RPF group demonstrated less enhancement. Signal intensity values on T2-weighted images were not useful for differentiating these conditions.

    Fibroblast Growth Factor-23 Levels Are Associated with Vascular Calcifications in Peritoneal Dialysis Patients
    (KARGER, 2013) VELİOĞLU, ARZU; Asicioglu, Ebru; Kahveci, Arzu; Arikan, Hakki; Koc, Mehmet; Tuglular, Serhan; Ozener, Cetin Ishak
    Background: The aim of the study was to assess the relationship between fibroblast growth factor-23 (FGF-23) and vascular calcifications (VC) in peritoneal dialysis (PD) patients. Methods: A cross-sectional study was performed in 55 PD patients who underwent pelvic X-ray to assess for VC. Patients with and without linear calcifications were recorded. Results: Fifteen patients (27.3%) had linear calcifications on pelvic X-ray. FGF-23 levels were higher in patients with VC (299.5 (30.4-2,410.0) vs. 74.4 (14.8-1,030) pg/ml, p < 0.01). Diabetic patients had lower FGF-23 values (43.2 (14.9-134.0) vs. 103.5 (14.8-2,410) pg/ml, p < 0.01). Patients with residual renal function (RRF) had lower FGF-23 levels (70.6 (14.8-513) vs. 179.5 (30.4-2,410) pg/ml, p = 0.06); however, this did not reach statistical significance. FGF-23 levels, age, creatinine, Ca, dialysis duration and HbA1c were positively correlated with VC, whereas RRF, Ca intake and ALP were negatively associated. Multivariate logistic analysis confirmed FGF-23 levels, age, dialysis duration and RRF to be associated with VC. Conclusions: FGF-23 levels are associated with VC in PD patients. Further studies are needed to clarify whether it is simply a marker or a potential factor. It may prove to be an important therapeutic target for VC management. (C) 2013 S. Karger AG, Basel
