    Effects of hepatitis B surface antigen (HBsAg) positivity of donors in HBsAg(+) renal transplant recipients: comparison of outcomes with HBsAg(+) and HBsAg(-) donors
    (Wiley, 2016) Yilmaz, V. T.; Aliosmanoglu, I.; Erbis, H.; Ulger, B. V.; Cetinkaya, R.; Suleymanlar, G.; Kocak, H.
    AimThe aim of this study was to determine the effects of hepatitis B surface antigen (HBsAg) positivity of the donors on graft survival and liver complications in HBsAg(+) renal transplant recipients. Patients and methodA group of 55 patients who underwent renal transplantation (RTx) in our hospital between 2001 and 2012 were included in the study. Patients were divided into 2 groups. Group 1 (n=50) consisted of HBsAg(+) renal transplant recipients (RTR) whose donors were HBsAg(-). In Group 2 (n=5), RTR and donors were both HBsAg(+). Lymphocyte cross matches, number of mismatches, donor types, renal replacement treatment modalities, drugs of induction treatment, and preoperative hepatitis B virus DNA titers of the groups were similar. In Group 1, 42 patients were taking lamivudine, 3 patients were taking entecavir, and 5 patients were taking tenofovir. All of the patients in Group 2 were taking lamivudine. Patient and graft survival rates, graft functions, acute hepatitis rates, acute rejection rates, and other clinical outcomes of the groups were compared. ResultsDemographic data of the groups were similar. Acute rejection rates (P=0.458), graft survival rates (P=0.515), and patient survival rates (P=0.803) were also similar. No significant difference was found between the groups in terms of acute hepatitis rate (P=0.511), glomerular filtration rate (calculated by Modification of Diet in Renal Disease formula) in the last follow-up (P=0.988), alanine aminotransferase levels (P=0.069), or delayed graft function rate (P=0.973). Rates of chronic allograft dysfunction and new onset diabetes mellitus after transplantation were similar. ConclusionOur study revealed that, RTx from HBsAg(+) donors to HBsAg(+) recipients is safe with antiviral treatment.

    A Successful Renal Transplantation Case After Stem Cell Transplantation
    (Elsevier Science Inc, 2015) Yilmaz, V. T.; Koksoy, S.; Ulger, B. V.; Salim, O.; Akbas, H.; Aliosmanoglu, I.; Erbis, H.
    Renal transplantation is the most effective treatment method for end-stage renal disease (ESRD). However, new treatment modalities are being investigated, such as immunotoleration, to avoid the acute and chronic side effects of immunosuppressant drugs. We report a case in which a man had undergone allogenic stem cell transplantation from his brother 16 years ago due to chronic myeloid leukemia, and who then developed ESRD due to arterial hypertension and underwent renal transplantation (Rtx) from the same brother. The patient was followed up without immunosuppression due to full chimerism.

    THE THYROID CANCER INCIDENCE IN AN ENDEMIC GOITER REGION AND THE RELATIONSHIP OF THYROID CANCER WITH NODULE DIAMETER
    (Editura Acad Romane, 2015) Ay, N.; Oz, A. B.; Alp, V.; Bahadir, M. V.; Yilmaz, V. T.; Dinc, B.; Ay, D.
    Objective. This study has two objectives. The first was to determine the cancer incidence in MNG cases, and to compare this with the thyroid cancer incidence in endemic goiter regions in our country and the rest of the world. The second objective was to evaluate the relationship between the dominant nodule diameter and the cancer incidence. Method. One hundred seventy-six patients who had presented to the Erzurum Oltu State Hospital General Surgery Clinic between October 2009 and March 2012 with the diagnosis of MNG, and who had undergone total thyroidectomy, were evaluated retrospectively. Findings. Papillary carcinoma was determined in 14 (8%) cases; medullary, anaplastic and follicular carcinoma were determined in 1 case each (0.6%). In 31 patients, the dominant nodule diameter was > 4cm, and malignancy was determined in 7 (22.6%) of them. Conclusion. The increase in the malignancy incidence was statistically significant in cases in which the dominant nodule diameter was > 4 cm. However, the frequency of thyroid papillary carcinoma was determined as 12.9% in MNG patients in whom the DND was > 4 cm.
