Öğe Acute angle-closure glaucoma precipitated by local tiotropium absorption(Academic Press Ltd- Elsevier Science Ltd, 2007) Oksuza, H.; Tamer, C.; Akoglu, S.; Duru, M.Acute angle-closure glaucoma is a rare form of glaucoma occurring when the filtration mechanism for the aqueous humor is obstructed by apposition of the peripheral iris to the trabecular meshwork. It may be precipitated by pupillary dilatation in a predisposed eye. In this case report, a possible relationship between local tiotropium absorption and acute angle-closure glaucoma attack is presented. (C) 2006 Elsevier Ltd.

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 Effects of feed refreshing frequency on growth and carcass characteristics of Awassi lambs(South African Journal Of Animal Sciences, 2007) Keskin, M.; Gul, S.; Sahin, A.; Kaya, S.; Duru, M.; Gorgulu, O.; Sahinler, S.Sixty, two-month old male Awassi lambs were used in this study to investigate the effects of feed refreshing (FR) frequencies on their growth and carcass characteristics over a period of 65 days, Treatments were: Feed refreshing at 2 h (FR2), 4 h (FR4), 8 h (FR8), 12 h (FR12) and 24 h (FR24) intervals. The lambs were fed individually, At the onset of each refreshing period the lambs were offered fresh feed ad libitum. Daily feed intakes, weekly live weights and carcass characteristics were recorded. Daily feed intakes per lamb per treatment were; 1.13 kg, 1.05 kg, 1.00 kg, 0.98 kg and 0.95 kg; daily gains were 193.6 g, 180.6 g, 148,6 g, 169.3 g and 146.4 g; feed conversion ratios (kg feed/kg gain) were 6.1, 6.7, 7.2, 7.2 and 7.5; hot carcass weights were 13.0 kg, 13.1 kg, 12.1 kg, 13.3 kg and 13.1 kg; dressing percentages were 42.3%, 42.4%, 39.9%, 40.2% and 41.2%; the proportion of muscle in the carcass was 52.0%, 55.2%, 55.6%, 55.8% and 54.8%; bone ratio was 20.4%, 20.3%, 21.9%, 21.1% and 20.9%; subcutaneous fat ratio was 16.9%, 14.2%, 12.9%, 12.7% and 14.0% and intramuscular fat ratio was 8.8%, 7.1%, 6.8%, 8.7% and 7.7% in FR2, FR4, FR8, FR12 and FR24 treatments, respectively. Results showed that frequent feed refreshing stimulated feed intake and daily gain without affecting carcass characteristics.Öğe Licorice induced hypokalemia, edema, and thrombocytopenia(Sage Publications Ltd, 2012) Celik, M. M.; Karakus, A.; Zeren, C.; Demir, M.; Bayarogullari, H.; Duru, M.; Al, M.Licorice originates from the root of Glycyrrhiza glabra, which has a herbal ingredient, glycyrrhizic acid, and has a mineralocorticoid-like effect. Chronic intake of licorice induces a syndrome similar to that found in primary hyperaldosteronism. Excessive intake of licorice may cause a hypermineralocorticoidismlike syndrome characterized by sodium and water retention, hypertension, hypokalemia, metabolic alkalosis, low-renin activity, and hypoaldosteronism. In this case report, an association of hypokalemia, edema, and thrombocytopenia that is developed due to the excessive intake of licorice is presented. There are case reports in the literature, which suggest that toxicity findings may emerge with hyperaldosteronism-like manifestations such as hypokalemia, edema, and hypertension. However, any knowledge of thrombocytopenia as a resultant was not encountered among these reported toxic effects. Our case is important because it shows that the excessive intake of licorice may cause a toxic effect in the form of thrombocytopenia. This report is the first presented case to show thrombocytopenia due to licorice syrup consumption.Öğe PROTECTIVE EFFECT OF THYMOQUINONE IN EXPERIMENTAL TESTICULAR TORSION(Elsevier Science Bv, 2010) Gokce, A.; Oktar, S.; Koc, A.; Gonenci, R.; Yalcinkaya, F.; Yonden, Z.; Duru, M.[Abstract Not Available]Öğe The protective role of N-acetylcysteine on cyclosporine A-induced nephrotoxicity in rats(Blackwell Publishing, 2006) Oksuz, H.; Sogut, S.; Koc, A.; Uz, E.; Tamer, C.; Yilmaz, H.; Duru, M.[Abstract Not Available]Öğe Reptile bite in pregnancy(Sage Publications Ltd, 2008) Duru, M.; Helvaci, M. R.; Peker, E.; Dolapcioglu, K.; Kaya, E.Reptile bites are rarely seen cases in emergency departments. But particularly in the warm summer months, the prevalence is relatively higher in rural areas. Snakebites during pregnancy is little known and only a few cases have been reported in the literature. However, in case of pregnancy, the outcomes may he different both for mother and the fetus. Interestingly, there is limited number of reptile bite cases during pregnancy in the literature. We report here a woman who was bitten at her 28th week of gestation. Obstetric consultation with ultrasonography was performed and seen that fetus was normal according to a 28-week gestation. We infused four vials of antiserum in a period of 1 h in a saline solution. In all, 30 min after the initiation of the antiserum infusion, the lesion started to regress. Her obstetric consultation was repeated 1 h, 36 h, and before discharge were performed and seen that the fetus was normal. After a period of five days, the patient and fetus were evaluated once more, and nothing was abnormal for both.
