    Effects of Preoperative Iron Deficiency on Transfusion Requirements in Liver Transplantation Recipients: A Prospective Observational Study
    (Elsevier Science Inc, 2013) Aydogan, M. S.; Erdogan, M. A.; Yucel, A.; Konur, H.; Bentli, R.; Toprak, H. I.; Durmus, M.
    The aims of this study were to determine the frequency of preoperative iron deficiency in adult living donor liver transplantation patients and to investigate its relationship with the need for intraoperative transfusion. Between September 1, 2011, and June 1, 2012, 103 patients scheduled for liver transplantation were included in this prospective study. Patients were divided into 2 groups according to baseline iron status: an iron-deficient group and a non deficient (normal iron profile) group. Iron deficiency was assessed on the basis of several parameters, including transferrin saturation, levels of ferritin, soluble transferrin receptor, C-reactive protein, and peripheral blood smear. Preoperative iron deficiency was diagnosed in 62 patients. Preoperative iron deficiency was associated with low preoperative hemoglobin levels (P = .01) and a high rate of intraoperative transfusion (P < .0001). Preoperative iron deficiency is prognostic factor for predicting intraoperative transfusion requirements. These findings have important implications for transfusion practices for liver transplant recipients.

    A rare pathology that cause of hearing loss and deafness: Nasopharyngolaryngeal amyloidosis
    (Galenos Yayincilik, 2012) Toplu, Y.; Bentli, R.; Can, S.; Samdanci, E.; Kizilay, A.
    Amyloidosis is a disease that characterized by deposition of an abnormal fibrillary protein in the extracellular area of various tissues and organs. It is more commonly seen in males and in the over 40 age period. Even though immunologic factors are under an immense suspicion, its etiology is still unknown. Amyloidosis is observed in 3 groups as primary systemic amyloidosis, secondary systemic amyloidosis and localized amyloidosis according to its prevalence. Amyloidosis is demonstrated in systemic form generally, but it may be found as localized form in some organs very rarely. Larynx is the most common involved site of localized amyloidosis. In this paper we described very rare form of localized amyloidosis; rhinonasopharingolaryngeal amyloidosis that hasn't been defined in our country previously.

    Serum asymmetric-dimethylarginine, apelin and NT-pro BNP levels in dialysis patients
    (Wolters Kluwer Medknow Publications, 2020) Bentli, R.; Taskapan, H.; Taskapan, M. C.; Dogan, A.
    Background: The relationships among serum Apelin, Asymmetric- dimethylarginine (ADMA), N-terminal probrain natriureticpeptide (NT-proBNP) levels, and blood pressures in dialysis patients are not well known. Materials and Methods: Age and sex matched 30 hemodialysis (HD), 30 peritoneal dialysis (PD) patients, and 20 healthy controls were recruited. Serum apelin-36, ADMA, NT-proBNP levels, and blood pressures of both patients and healthy controls were measured and compared. Results: Serum ADMA and Apelin levels in HD patients were significantly higher than in PD patients. In multiple regression analyses the predictors of higher serum apelin levels were higher BMI, higher ADMA and lower systolic blood pressure. The predictors of serum ADMA levels were being on HD. The predictors of serum NT-proBNP levels were lower serum albumin and higher systolic blood pressure. Conclusion: Being on HD is a predictor of high ADMA levels. HD might be less effective on ADMA removal than PD. It seems that higher serum apelin levels related with lower sytolic blood pressure levels, whereas higher NT-proBNP levels related with higher sytolic blood pressure levels indicating potential roles as independent prognostic factors for systolic hypertension in dialysis patients.
