    Bladder Rupture and Urine Fistula Between-Bladder and Supracondylary Pin Tract After Pelvis Fracture: A case Report
    (Derman Medical Publ, 2015) Oztemur, Zekeriya; Golge, Umut Hatay; Picakci, Omer; Tezeren, Gunduz; Bulut, Okay
    One of the most important complications of pelvic fractures is bladder rupture. Potential complications of pelvic fractures caused by bladder ruptures are vesicovaginal. vesicorectal, vesicoutedne and urethra rectal fistulas. Along with bladder rupture, which is rarely encountered in the literature, the case of urinary fistula from pin tract in femur supracondylar region was represented. The case of the bladder rupture induced by pelvic fracture that associated with urinary fistulisabon between bladder and pin tract from femur supracondylar region was reported.

    Comparing extracorporeal shock wave and hyaluronic acid in a rabbit cartilage defect model: the effects of ESW on cartilage defect
    (Tubitak Scientific & Technological Research Council Turkey, 2013) Oztemur, Zekeriya; Ozer, Hatice; Golge, Umut Hatay; Altuntas, Emine Elif; Bulut, Okay
    Aim: To compare the efficiency of extracorporeal shock wave (ESW) treatment with hyaluronic acid (HA) viscosupplementation in an experimental rabbit cartilage defect model. Materials and methods: A total of 24 New Zealand rabbits were randomly divided into 4 groups: HA, ESW, ESW + HA, and control. Chondral defects were created in the left knees of the rabbits. HA viscosupplementation was performed on the HA and ESW + HA groups, and after 24 h, 0.16 mJ/mm2 ESW was performed on the ESW and ESW + HA groups. After an 8-week follow-up, the rabbits were sacrificed and histopathological examination of the defects was carried out. In addition, immunohistochemistry was performed by the avidin-biotin peroxidase method using vascular endothelial growth factor (VEGF), transforming growth factor beta 1 (TGF-beta 1), and type II collagen antibodies, and the results were evaluated semiquantitatively. Results: There was a significant difference between the control group and the ESW group in terms of Pineda score and type II collagen expression; between the control group and the HA group in terms of Pineda score, VEGF expression, type II collagen expression, and TGF-beta 1 expression; and between the control group and the ESW + HA group in terms of Pineda score, VEGF expression, type II collagen expression, and TGF-beta 1 expression. Conclusion: The results show that both treatment methods have positive therapeutic effects on the articular cartilage defect model in terms of the parameters studied.

    Neutrophil to Lymphocyte Ratio May Be a Diagnostic Marker for Prosthetic Joint Infection
    (Derman Medical Publ, 2016) Golge, Umut Hatay; Kaymaz, Burak; Pazarci, Ozhan; Kilinc, Seyran; Oztemur, Zekeriya; Bulut, Okay
    Aim: Total knee arthroplasty (TKA) is an effective and successful procedure but the outcome may occasionally be compromised by complications such as periprosthetic joint infection (PJI). Blood neutrophil to lymphocyte ratio (NLR) is a simple marker of subclinical inflammation that can be easily obtained from the differential White Blood Cell count. This study aims to to analyze the predictive ability of NLR for the diagnosis of PJI. Material and Method: Patients who were diagnosed as grade 4 gonartrosis and operated for total knee arthroplasty between years 2007-2014 were evaluated. Thirty patients with PJI were included in the study as Group I and hematological tests including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), white blood cell count (WBC) and neutrophil to lymphocyte ratio (NLR) of the patients were evaluated retrospectively. Preoperative and postoperative 6th month NLR values of the patients were compared. Also 103 age matched patients operated for total knee arthroplasty with no sign of infection were included in the study as controls (Group II). Patients in Group I and Group II were also compared in terms of NLR. Results: Thirty patients (17 female, 13 male) were present in Group I (patients with PJI and treated with two staged revision surgery) and 103 patients (94 female, 9 male) were present in Group II (patients operated for total knee arthroplasty and had no sign of infection during the follow up period). NLR has been found to decrease from 3.2+/-0.7 to 2.2+/-0.5 when compared between the preoperative and postoperative 6th month period (p=< 0,001). NLR has been found to be 2.1+/-0.7 in Group II and 3.2+/-0.7 in Group I at preoperative period. (p=< 0,001). The value of 2.45 was found to be cut-off point for infection. Discussion: NLR can be used as marker for PJI together with the other markers as ESR and CRP to increase the accuracy of the diagnosis.
