Brucella Endocarditis Caused by Brucella Melitensis
(2013) Akdag, S.; Akyol, A.; Simsek, H.; Şahin, M.; Yaman, M.
We present a rare case of brucella endocarditis, forming a vegetation on the mitral valve. The definitive diagnosis has been made with clinical suspicion, positive serology, the demonstration of the vegetation with the echocardiography and with the production from the multiple blood culture of brucella melitensis and from the excised valve. Our patient has been successfully treated with specific antibiotherapy and the surgery of replacement of mitral valve. Our aim in presenting the case is to remind the infective endocarditis which is due to this factor in the regions like our country which is endemic for brucellosis.

A New Echocardiographic Parameter of Arterial Stiffness in End-Stage Renal Disease
(Urban & Vogel, 2014) Sahin, M.; Simsek, H.; Akyol, A.; Akdag, S.; Yaman, M.; Aydin, C.; Gumrukcuoglu, H. A.
Background. Cardiovascular disease is the leading cause of death among patients with end-stage renal disease (ESRD). Arterial stiffness is an independent predictive parameter of overall and cardiovascular mortality in these patients. However, the defined procedures for the measurement of arterial stiffness are time consuming and not practical in daily practice. Methods. The study population included 50 patients with ESRD who were treated with hemodialysis (HD; n=23) or peritoneal dialysis (PD; n=27) and 70 age-and sex-matched control subjects. Aortofemoral pulse wave velocity (PWV), carotid intima-media thickness (CIMT), and color M-mode propagation velocity of the descending aorta (aortic propagation velocity, APV) were measured. Results. Compared to the control group, the patients with ESRD had significantly lower APV (46.4 +/- 12.4 vs. 58.5 +/- 8.5, p<0.01) and higher PWV (10.5 +/- 2.5 vs. 9.2 +/- 1.2, p<0.01) and CIMT (0.66 +/- 0.15 vs. 0.43 +/- 0.06, p<0.01) measurements. There were significant correlations between APV and CIMT (r=-0.769, p<0.001), APV and PWV (r=-0.682, p<0.001), and PWV and CIMT (r=0.564, p<0.001). There were no significant differences in APV and PWV between the PD and HD patients. Conclusion. Arterial stiffness is an important indicator of atherosclerosis and arterial aging in patients with ESRD. The measurement of APV is an easy and practical new echocardiographic method and may be used to identify arterial stiffness in these patients.
A Novel Echocardiographic Method as an Indicator of Endothelial Dysfunction in Patients With Coronary Slow Flow
(verduci Publisher, 2013) Simsek, H.; Sahin, M.; Gunes, Y.; Akdag, S.; Akil, M. A.; Akyol, A.; Yaman, M.
BACKGROUND: To improve clinical outcomes, noninvasive imaging modalities have been proposed to measure and monitor atherosclerosis. Endothelial dysfunction is considered the first stage in the development of atherosclerosis. Brachial artery flow-mediated dilatation (FMD) has been impaired in patients with coronary slow flow (CSF). Recently, color M-mode derived propagation velocity of descending thoracic aorta (aortic propagation velocity-AVP) was shown to be an ultrasonographic marker for atherosclerosis. AIM: To assess endothelial function in patients with CSF and the correlation of AVP with FMD. MATERIALS AND METHODS: FMD and AVP were measured in 90 patients with CSF and 39 patients having normal coronary arteries (NCA) detected by coronary angiography. RESULTS: Compared to patients with normal coronary arteries patients having CSF had significantly lower AVP (39.1 +/- 8.4 vs. 53.7 +/- 12.7 cm/s, p < 0.001) and FMD (5.6 +/- 3.2 vs. 17.6 +/- 4.4 %, p < 0.001) measurements. There were significant correlations between AVP and FMD (r = 0.524, p < 0.001). CONCLUSIONS: Transthoracic echocardio-graphic determination of color M-mode propagation velocity of descending aorta is a simple practical method and correlates well with coronary slow flow and brachial endothelial function.
Percutaneous Transluminal Angioplasty in Haemodialysis Patients With Central or Peripheral Venous Stenosis
(Ondokuz Mayis Universitesi, 2016) Yaman, M.; Sahin, M.; Simsek, H.; Gumrukcuoglu, H.A.; Tuncer, M.; Gunes, Y.; Akdag, S.
Dysfunction of arteriovenous fistulae (AVF), which result from peripheral or central venous occlusive illness, occurs very often in haemodialysis patients. In therapy, endovascular open procedures are prefered. Our study illustrated the clinical success of percutaneous transluminal angioplasty (PTA) for the treatment of these patient. A retrospective analysis was applied on patients presenting during a 2-years term with haemodialysis failure and ipsilateral arm swelling coherant with peripheral and/or central venous stenosis. PTA was performed as clinically and angiografically indicated. Technical success of PTA was defined less than 30% residual stenosis and clinical success was illustrated by resolution of pain and edema along with preservation of the AVF. Our study shows a subgroup of 26 patients that presented with symptomatic peripheral or central venous occlusive disease. Mean follow-up was 12.4 months (range, 3-24 months). PTA was successful in 26 patients 11 of whom were with central lesions and 15 of whom were with peripheral lesions. We were stated for central lesions PTA had a priority patency rates of 81.8%, 60%, 37.5% and supported primary patency rates of 90.9%, 70%, 62.5% at 3, 6, 12 months. For peripheral lesions, primary patency rates of 86.7%, 78.5%, 66.6% at 3, 6 and 12 months and assisted primary patency rates of 93.3%, 85.7% and 75%, separately. PTA for central and peripheral venous stenosis is be a successful and safe procedure in hemodialysis patients. In patients with lesions that are responsible for dilation, continuous functional access in the affected extremity is sustained, especially for patients with peripheral venous stenosis. © 2016 OMU.
The Seroprevalance of Toxoplasma Gondii in Sheep, Goats and Cattle Detected by Indirect Haemaglutination (Iha) Test in the Region of Van, Turkey
(2003) Tutuncu, M.; Ayaz, E.; Yaman, M.; Akkan, H.A.
This study was carried out on sheep, goats and cattle in order to determine the seroprevalence of toxoplasmosis in the province of Van. Indirect Haemaglutination (IHA) test was used to detect Toxoplasma gondii antibodies in 305 ruminants (150 sheep, 104 cattle and 51 goats) obtained from the city center of Van and its region. The sera were tested for Toxoplasma gondii antibodies between 32 and 1024 titres. Samples with titres 64 and greater than this were considered as positive. The prevalaence of the positive sera were found to be 52 (34.6%) for sheep, 8 (7.6%) for cattle and 17 (33.3%) for goats. The results indicate that Toxoplasma gondii infection in ruminants in the province of Van is widespread.
