    The importance of the mean platelet volume in the diagnosis of supraventricular tachycardia
    (Makerere Univ, Fac Med, 2013) Ocak, T.; Erdem, A.; Duran, A.; Tekelioglu, U.; Ozturk, S.; Ayhan, S.; Ozlu, F. M.
    Background: This retrospective study aimed to investigate the diagnostic relation between the mean platelet volume (MPV) and supraventricular tachyarrhythmia (SVT) in patient with documented atrial tachyarrhythmia in the emergency department (ED). Methods: Two study groups were compared; a SVT group with arrive at the ED with documented SVT (n=122) and 100 healthy adult without any palpitation symptom, arrhythmic disease, and with normal physical examination results that were brought for checkups to the cardiology polyclinic were classified as control group. Blood samples were obtained from all patients for determining the hematologic counts and MPV during first hour in ED period. Results: In terms of the focus of the study, hemoglobin, neutrophil count, mean cell volume (MCV), red cell distribution width (RDW), platelet, white blood cell (WBC), and lymphocyte counts were similar in both group (p>0.05). MPV in the SVT group was significantly higher than in the control group (9.12 +/- 1.22 flvs 8.64 +/- 0.89 fl, p<0.001). Multivariate logistic regression analysis showed that just MPV was independent predictor of SVT in patients with palpitation in ED (odds ratio [OR] 8.497, 95% confidence interval (6.181 to 12.325), p=0.012). Conclusions: The present study described that MPV is helpful parameter for the diagnosis of SVT in emergency department, for the first time in the literature.

    Significance of bacteriuria and leukocyturia in the outpatients with heart failure
    (Verduci Publisher, 2012) Kucukbayrak, A.; Tas, T.; Kemahli, E.; Ayhan, S. S.; Ozturk, S.; Ozlu, M. F.; Erdem, A.
    Aim: To investigate the relationship between severity of illness and hospitalization with the presence of leukocyturia and bacteriuria in outpatients with heart failure (HF). Patients and Methods: Four hundred three patients admitted with the diagnosis of HF to cardiology outpatient clinic were included in this study. According to New York Heart Association (NYHA) classification, the patients were divided into two groups to be group A (decompensated) as stage 3 or 4 and group B as stage 1 or 2 (compensated HF). All subjects underwent standard 12-lead ECG and echocardiography. In all patients, full blood, biochemical tests as liver and kidney function tests, full urinary analysis (FUA) and thyroid function tests were analyzed. Mid-stream urine for culture was taken for the leukocytes number >= 5 mm(3). Results: The mean leukocyte number (MLN) in urine of patients was 16.56 +/- 13.63 in Group A and was 3.74 +/- 5.31 in Group B (p < 0.000). The moderately positive correlation was found between the MLN and NHYA class in all patients (r = 0.526; p < 0.000). In receiver operating characteristic (ROC) curve analysis, the optimal cut-off value of leukocytes in urinalysis to predict hospitalization of CHF was >= 5, with 76.1% sensitivity and 75.7% specificity (area under the curve 0.825, 95% confidence interval 0.781 to 0.862, p = 0.000). Conclusions: We found that the numbers of leukocytes in urinalysis of hospitalized patients with HF were significantly higher than non-hospitalized persons. Also, number of leukocyte in urinalysis was positively correlated with NYHA class of HF patients. Namely, leukocyturia may be an indicator of decompensations in HF patients.
