Diagnostic and clinical value of F-18 FDG PET/CT in thoracic carcinoid tumors

Aim: To assess the correlation between standard uptake values ​​(SUVmax, SUVmean) and Ki-67 in typical lung carcinoid (TC) tumors. Methods: Thirty-eight patients with thoracic masses sent for diagnosis and staging were included in the study. F-18 FDG PET / CT was applied to all patients before the operation. The patients were operated by thoracic surgery clinic. By determining different cut-off values ​​(2.5 and 0.5), SUVmean and SUVmax values ​​of the lesions from the curves drawn to the area of ​​interest were calculated. Results: Thirty-eight patients were included in the study (18 women, 20 men). The average age of our patients was 45. Pathological diagnoses of all patients were determined as typical carcinoids. Eight of our patients had parenchymal lesions and twenty of them had endobronchial lesions. The average of the Ki-67 index was about 3-4% (range 1-10%). No recurrence or death was detected after resection in the 5-year follow-up period. SUVmean1 and SUVmean2 values ​​were statistically significant when compared with SUVmax1 and SUVmax2 values ​​(p <0.05). Conclusion: We think that the SUVmean and Ki-67 index may be an important prognostic indicator that identifies high-risk subgroups. It is thought that Ki-67 indices may correlate well with SUVmean values, and low cut-off values ​​may be more suitable for diagnosis and prognosis in typical carcinoid tumors. SUVmean values ​​can be used for lung carcinoid tumors and F-18 FDG PET/CT imaging is useful in the approach to carcinoid tumors of the lung before thoracic surgery. &nbsp

Investıgatıon of hazardous waste potentıal of Nevsehır

Bu çalışmada, Atık Yönetimi Yönetmeliği ekinde yer alan ve A ve M kodu ile sınıflandırılan atıkları temel alarak Nevşehir ili için tehlikeli atık envanteri oluşturulmuştur. Bu envantere göre Nevşehir ilinin potansiyel tehlikeli atık miktarı tahmin edilmiştir. Böyle bir envanterin gerekliliği tehlikeli atık miktarlarının ve Nevşehir’de atık dağılımının etkin bir tehlikeli atık yönetim sistemi için teşkil ettiği önemden kaynaklanmaktadır.“LIFE TCY/TR/000292 Türkiye’de Sanayiden Kaynaklanan Tehlikeli Atıkların Yönetiminin İyileştirilmesi” projesi kapsamında internet üzerinden online olarak giriş yapılmasını sağlayan Tehlikeli Atık Beyan Sistemi (TABS) 2009 yılında hazırlanmıştır. 2009 yılından itibaren her yıl Mart ayı sonuna kadar tehlikeli atıkların beyanı online olarak yapılmaktadır. Bu çalışmada, “Çevre Bilgi Sisteminde” “Atık Yönetimi Uygulaması” başlığı altıda bulunan “Atık Beyanı(TABS)” sistemine yapılan beyanlar dikkate alınarak çıkarılmıştır. Envanter çalışması oluşturulurken, Nevşehir ilinde bulunan TABS sistemine kayıtlı 377 adet firmanın 2009-2014 yılları arasındaki beyanları incelenmiştir. 2009 yılında onaylanmış beyanlara göre tehlikeli atık miktarı 533.389 kilogram iken bu değer 2014 yılına kadar artan ve azalan değerler göstermiştir.2014 yılında onaylı beyanlara göre tehlikeli atık miktarı 482.042 kilogramdır. Tez çalışmasında yıllara göre yapılan beyanlardaki aksaklıklar ve yapılması gerekenler hakkında bilgiler verilmiştir.In this study, a hazardous waste inventory for Nevsehir province was developed based on wastes identified as hazardous in the Regulation on Control of Hazardous Wastes coded with A and M. Based on this inventory, potential hazardous waste quantity of Nevsehir was estimated. Necessity of such inventory arises from the importance of acquiring information on the amount of hazardous wastes generated and on their province wide distribution for a sound waste management system for Nevsehir. Hazardous Waste Declaration System (TABS) which enables online access on internet within the context of “LIFE TCY/TR/000292 Improving of Hazardous Waste Management Arose from Industry in Turkey Project’’ was prepared in 2009. Hazardous waste declaration has been made online till the end of March every year since 2009. This study was derived from the declarations collected by considering the declarations made to the Waste Management Practice under the title of ‘’Waste Declaration (TABS)’’in Environment Information System. While creating the Inventory, 377 firms’ 2009-2014 declaration, that is registered at the Hazardous Waste Declaration System (TABS) in Nevsehir, have been examined. According to the approved statement in 2009, while the amount of hazardous waste is 533.389 kilograms, the value has increased and decreased until 2014. According to the approved statement in 2014, the amount of hazardous waste is 482.042 kilograms. The information about the troubles according to the declaration and what could be done by years in the thesis

The Diagnosis of Yo-Yo Reflux with Dynamic Renal Scintigraphy in a Patient with Incomplete Ureteral Duplication

The diagnosis of yo-yo reflux in patients with incomplete upper collecting system duplications is difficult. We report a case with recurrent urinary tract infections and ultrasonographically detected duplication in the left collecting system in which the presence of yo-yo reflux is demonstrated with dynamic renal scintigraphy.

The prevalence of microalbuminuria and relevant cardiovascular risk factors in Turkish hypertensive patients.

Objectives: A growing body of data illustrates the importance of microalbuminuria (MAU) as a strong predictor of cardiovascular risk in the hypertensive population. The present study was designed to define the prevalence of MAU and associated cardiovascular risk factors among Turkish hypertensive outpatients. Study design: Representing the Turkish arm of the multinational i-SEARCH study involving 1,750 sites in 26 countries around the world, a total of 1,926 hypertensive patients from different centers were included in this observational and cross-sectional survey study. Patients with reasons for a false-positive MAU test were excluded. The prevalence of MAU was assessed using a dipstick test, and patients were inquired about comorbidities, comedication, and known cardiovascular risk factors. Results: The overall prevalence of MAU was 64.7% and there was no difference between genders. Most of the patients (82.5%) had uncontrolled hypertension, 35.6% had dyslipidemia, and 35.5% had diabetes, predominantly type 2. Almost one-third of the patients (26.4%) had at least one cardiovascular-related comorbidity, with 20.3% having documented coronary artery disease (CAD). Almost all patients (96.8%) had one or more risk factors for cardiovascular disease in addition to hypertension, including family history of myocardial infarction or CAD, diabetes, dyslipidemia, lack of physical exercise, and smoking. A trend towards higher MAU values in the presence of CAD was determined. Conclusion: Microalbuminuria tests should be routinely used as a screening and monitoring tool for the assessment of subsequent cardiovascular morbidity and mortality among hypertensive patients. © 2011 Turkish Society of Cardiology
