Öğe The evaluation of T1-201 myocardial perfusion scintigarphy by visual and quantitative analysis methods in the diagnosis of coronary artery disease [T1-201 miyokard perfüzyon sintigrafisinin koroner arter hastali?indaki yerinin görsel ve sayisal analiz yöntemleri ile de?erlendirilmesi](Turkiye Klinikleri, 2010) Serdengeçti M.; Entok E.; Sari O.; Ilgan S.Objective: The importance of Tl-201 myocard perfusion SPECT(MPS) imaging in the diagnosis of coronary artery disease was evaluated and significant difference between visual and quantitative analysis and istatistically significant correlation between quantitative values and percentage of coronary artery stenosis was inquired. Material and Methods: Sixty patients who were applied both coronary angiography and TI-201 MPS were included into study. SPECT imaging were assessed by visual and quantitative analysis. The sensitivity and specificity of SPECT were defined by assuming coronary angiography as"gold standart". It was compared that SPECT analysis methods each other and percentage of stenosis determined by selective coronar angiography and quantitative values. Results: There was no significant difference between visual and quantitative analysis in the diagnosis of coronary artery disease. There was istatistically significant correlation between percentage of coranary artery stenosis and quantitative values of extent (r= 0.657, p< 0.002) and severity (r= 0.684, p< 0.001). Conclusion: It is concluded that TI-201 MPS imaging has high sensitivity and specificity in the diagnosis of coronary artery disease and there is no significant difference between visual and quantitative analysis. There is istatistically significant correlation between quantitative extent and severity values and percentage of coronary artery stenosis.

We report a 77-year-old male patient with urinary frequency and constipation. Fine needle biopsy from prostate was suspicious of squamous cell carcinoma of the prostate. Whole body positron emission tomography/computed tomography scan revealed high fluorodeoxyglucose uptake in prostate gland. Transurethral resection confirmed the diagnosis. In contrast to prostatic adenocarcinoma, high fluorodeoxyglucose accumulation was observed in the primary tumor of the prostate gland. © 2014 Gonca Kara Gedik et al.Öğe Insomnia in rural communities and Dysfunctional Beliefs and Attitudes about Sleep as a risk factor of Insomnia(2013) Kocoglu D.; Akin B.; Cingil D.; Sari O.The aim of the study was to define the prevalence of insomnia symptoms in rural regions and to determine the relationship between insomnia and the dysfunctional beliefs and attitudes about insomnia, and other risk factors. We used an own survey that included the Insomnia Severity Index and the Dysfunctional Beliefs and Attitudes about Sleep Scale. The study population was composed of individuals aged from 18 to 65 years from two rural areas. In total, 523 individuals were included in our study. Insomnia symptoms prevalence was determined as: 37.3% subthreshold insomnia, 9.2% moderate severe insomnia and 0.4% severe insomnia. Significant risk factors for insomnia were having at least one of the problems of sleep walking, sleep talking and sleep bruxism (OR: 2.163 CI: 1.320-3.543) and dysfunctional beliefs and attitudes such as worrying about insomnia (OR: 1.068 CI: 1.037-1.100). According to the multiple regression analysis, the following are also determinants of insomnia score: the worry about insomnia (?=0.380) and the use of medication (?=0.098) dimensions of Dysfunctional Beliefs and Attitudes About Sleep Index, having at least one of the problems of sleep walking, sleep talking and sleep bruxism (?=0.131) and being obese or overweight (?=0.083).
