Öğe Association of left ventricular diastolic function abnormalities with aortic elastic properties in asymptomatic patients with type 2 diabetes mellitus. A tissue doppler echocardiographic study(Wiley, 2008) Seyfeli, E.; Duru, M.; Saglam, H.; Akgul, F.; Kuvandik, G.; Kaya, H.; Yalcin, F.Background: The aim of this study was to investigate the association between the aortic elastic properties and the left ventricular diastolic function measured by tissue Doppler echocardiography (TDE) in asymptomatic type 2 diabetes mellitus. Methods: Fifty-seven asymptomatic patients with type 2 diabetes (33 women, mean age: 49 +/- 6 years) and 25 healthy control subjects (19 women, mean age: 46 +/- 7 years) were included in the present study. Diastolic filling indices were measured by conventional (CE) and tissue Doppler echocardiography. The aortic elastic properties [Aortic stiffness index (ASI), aortic distensibility and strain] were measured as previous definition. Results: Compared with control subjects, the ratio of LV diastolic abnormalities measured by CE and TDE were found higher in patients with type 2 diabetes (36% and 73.6%, p = 0.001, respectively, and 52% and 89.4%, p < 0.001, for septal annulus; 48% and 89.4%, p < 0.001 for septal basal respectively). The ASI was significantly higher (p < 0.001), aortic distensibility and aortic strain were also significantly lower in patients with type 2 diabetes than control subjects (p < 0.001 and p < 0.001 respectively). In the regression analysis, Ao distensibility was correlated to age (beta = -0.299, p = 0.004), septal basal Em/Am ratio (beta =0.543, p < 0.001) and HDL-cholesterol (beta = 0.192, p = 0.039). ASI was also correlated only to age (beta = 0.255, p = 0.044), the presence of diabetes mellitus (beta = 0.304, p = 0.009), mitral A wave (beta = 0.322, p = 0.013) and mitral annulus Em wave (beta = -0.505, p < 0.001). Conclusion: The aortic elastic function is impaired in asymptomatic patients with type 2 diabetes. Increased ASI and decreased Ao distensibility are closely associated with diastolic filling indices measured by CE and TDE.Öğe Effect of obesity on P-wave dispersion and QT dispersion in women(Nature Publishing Group, 2006) Seyfeli, E.; Duru, M.; Kuvandik, G.; Kaya, H.; Yalcin, F.Objective: The aim of this study was to investigate the effect of obesity on dispersion of P-wave duration and QTc interval in obese women. Methods: Forty-two obese women (Body mass index (BMI) 4073 kg/m(2), mean age 4579 years) and compared age-matched (BMI 2271 kg/m(2), mean age 41 +/- 6 years) twenty-five non-obese women were included in our study. Maximum and minimum P-wave duration, P-wave dispersion (difference between the maximum and the minimum P-wave duration), maximum and minimum QTc interval, and QTc dispersion (the difference between the maximum and the minimum QTc interval) were measured from 12-lead ECG. ECG's were transferred to a personal computer via a scanner and then used for magnification of 400 times by Adobe Photoshop software. Results: There was significant difference in BMI (40 +/- 3 vs 22 +/- 1 kg/m(2), P < 0.001, respectively) between obese and non-obese women. Obese women had higher Max. P-wave duration (116711 vs 94714 ms, P < 0.001), P-wave dispersion (51715 vs 26711 ms, P < 0.001), Max. QTc interval (449738 vs 419730 ms, P < 0.001) and QTc dispersion ( 57723 vs 38715 ms, P < 0.001) compared to non-obese women. A significant correlation was found between BMI and Max. P-wave duration (r = 0.584, P < 0.001), P-wave dispersion (r = 0.621, P < 0.001), Max. QTc interval (r = 0.410, P < 0.001), and QTc dispersion (r = 0.429, P < 0.001). In the linear regression analysis, compared to co-morbidity factors such as age, hypertension, diabetes mellitus and smoking, there was significant association between only BMI and electrocardiographic values (P-wave and QTc dispersion). Conclusion: We concluded that obesity caused significant increase in P-wave and QTc dispersion. Therefore, obese women may not only be under the risk of ventricular arrhythmias, but also they may under the risk of atrial arrhythmias.Öğe Epidemiology and cost of burns in emergency department during Syrian civil war(Comenius Univ, 2018) Kuvandik, G.; Ucar, E.; Karakus, A.BACKGROUND: We aimed to emphasize the importance of regional hospitals' capacities and emergency services for burn patients in war and disaster situations, in addition to assessing the costs and clinical situations of seriously burned patients who have come to the emergency service due to the bomb and heater burst during the Syrian civil war. METHODS: In this study, we analyzed these 217 burn patients and analyzed these patients' data for retrospective analysis. RESULTS: Burn patients were more often seen during the winter months. The majority of the patients were children, young adults and male (1-16 age, 95 % burn, 44 %, 17-40 age 94 % burn, 44 %, >= 41-65 age, 28 % burn, 12 %). The most common body surface burns >= 20 % body surface in surviving patients n = 184, 78 % were determined. 14 of the burned patients died within the first 24 hours. The total cost of the burned patients in the emergency unit was observed to be 33.4 +/- 25.9 Turkish Lira (10.2-6813.2). CONCLUSION: The present study showed that burn patients need much longer treatment time. The need for trained personnel in case of mass disasters and warfare, the identification of burn intensive care units and hospitals to be referred is important (Tab. 2, Fig. 4, Ref. 23).

V.; Sogut, S.; Kaya, H.; Bozkurt, S.Background: We tried to understand whether or not there is a significant etiopathogenetic relationship between irritable bowel syndrome (IBS) and cholelithiasis. Methods: Consecutive patients with upper abdominal discomfort were included into the study. Routine hematologic and biochemical tests, an abdominal ultrasonography, and a questionnaire for IBS was performed in all cases, and IBS is diagnosed according to Rome II criteria in the absence of red flag symptoms. Cholelithiasis cases were put into one group and age and sex-matched and randomly selected cases without cholelithiasis were put into the other group. Prevalences of smoking, normal weight, overweight, obesity, and IBS were detected in each group and compared in between. Results: One hundred and twenty-one patients with cholelithiasis were diagnosed. Ninety-seven (80.1%) of them were female, and their mean age was 53.4 +/- 9.9 (27-70) years. Interestingly, 92.5% (112 cases) of the cholelithiasis cases had excess weight and obesity was significantly higher in the cholelithiasis group (54.5% vs. 43.8%, p<0.05). Prevalence of IBS was nearly equal in both groups (43.8% in cholelithiasis vs. 42.1% in control cases, p>0.05). Conclusions: IBS probably is a cascade of many physiological events, being initiated with infection, inflammation, psychological disturbances-like stresses and eventually terminated with dysfunctions of genitourinary tract and probably some other systems of body via a low-grade inflammatory process. Although IBS probably has a much more complex mechanism than the current view and a higher prevalence in society, there is not a significant association between IBS and cholelithiasis.Öğe The Relationship between Mortality and Inflammation in Patients with Gastrointestinal Bleeding(Sage Publications Ltd, 2009) Koseoglu, Z.; Ozkan, O. V.; Semerci, E.; Aslan, A.; Yetim, I.; Ucar, E.; Kuvandik, G.The objective of this study was to investigate the association between mortality and inflammation in patients who were admitted to the emergency room with gastrointestinal bleeding. Patients (n = 96) managed at two medical centres were included in the study. Initial levels of serum C-reactive protein (CRP), haemoglobin and albumin, and leucocyte and thrombocyte counts for 28 patients who died were compared with those for the 68 patients who survived and were successfully discharged. The data were analysed using the chi(2)-test. Serum levels of CRP and leucocyte counts were significantly higher, and albumin and haemoglobin were significantly lower in patients who died compared with patients who survived. The increased levels of serum CRP and leucocyte counts, and decreased levels of albumin and haemoglobin were found to be independent risk factors for mortality. It is concluded that increased serum CRP levels and leucocyte counts combined with decreased albumin and haemoglobin levels on admission to the emergency room may be used as predictive factors of mortality in patients with gastrointestinal bleeding.
