The aim of this study is to have a solid basis for the effectiveness of the 18F-FDG-PET/CT imaging technique, which has known advantages for patients with head and neck cancers during staging and restaging prior to treatment and to compare this method with the corresponding clinical and radiological methods.A total of 139 patients with squamous cell head and neck carcinoma underwent PET/CT imaging. A total of 146 PET/CT imaging was performed in all patients. PET/CT imaging performed for staging and restaging in 36 and 103 patients, respectively. At least one conventional imaging (CI) as CT and/or MRI was performed for each one of the total patients. PET/CT studies revealed 66 true positive, 72 true negative, 4 false positive and 4 false negative results whereas the same values for CI were 65, 64, 4 and 6, respectively.When all studies were analyzed on the basis of lesion for PET/CT, specificity was 94.7%, and sensitivity being 94.2%, where as corresponding values for conventional imaging methods were found 94.1% and 91.5% respectively. Recurrent lesions have been detected with PET/CT and treatment management was changed in 29 of 139 patients.FDG-PET/CT improves the diagnostic accuracy in head and neck cancer patients.

Introduction and Aim:Many etiological reasons are blamed for enuresis nocturna (EN). The aim of this study was to research prevalence and severity of EN among elementary school-age children and sociodemographic risk factors related to it.Materials and Methods:The study was performed in three elementary schools in Ankara, Turkey between January and May 2011. It was planned to have 2500 students of 6–14 ages in the study. The questionnaire, which consisted of questions, aiming to evaluate the EN condition of participants and their characteristics, were distributed to the parents. It was observed that 2314 participants’ questionnaires (92.56%) were in accordance with evaluation criteria.Statistical Analysis:The relation between EN and the sociodemographic factors was evaluated through Chi-square test and logistic regression analysis.Results:The mean age of 2314 participants was 9.21 ± 2.08. 48.5% (n = 1123) of the students were male and 51.5% (n = 1191) were female. While the general EN prevalence was 9.9% (n = 230); 10.7% (n = 120) for males, as 9.2% (n = 110) for females. Statistical significant difference was determined between the two groups, with EN and without EN, regarding age groups (P < 0.001), education level of parents (P < 0.001, P < 0.001), and the number of sibling (P = 0.002), income level (P < 0.001), and positive family history (P < 0.001). However, logistic regression analysis revealed that there was a significant difference only between EN and age groups (odds ratio [OR] =4.42, P < 0.001), education level of mother (OR = 2.13, P = 0.017) and family history (OR = 0.12, P < 0.001).Conclusions:As a consequence, such factors as age groups, education level of parents, positive family history could be accepted as a risk of concerning EN. It is important to perform a detailed evaluation on population, carrying risk of having EN.

2-[18F]fluoro-2-deoxy-D-glucose-PET/CT improves the diagnostic accuracy in the differentiation of benign from malignant adrenal lesions in various cancer patients. Combined information obtained from PET/CT (SUVmax, T/L SUV ratio, visual analysis) and unenhanced CT (size, Hounsfield units measurement) is recommended for better differentiation.

The results of this study showed that NSD significantly impaired NMCVs in both sides and that septoplasty significantly improved NMCVs in both sides.

Objectives: To evaluate the role of pentraxin-3 (PTX-3) in determining the presence and severity of coronary atherosclerosis in patients with coronary artery disease (CAD). Subjects and Methods: Ninety-five patients (77 males and 18 females) who underwent elective coronary angiography were enrolled in this study. Patients with heart failure, renal failure, diabetes and thyroid disease were excluded. The study population was divided into 3 groups: individuals with normal coronary arteries, patients with critical CAD (n = 35) and patients with noncritical CAD (n = 36). The association of PTX-3 levels with the presence and severity of CAD and the number of involved vessels were analyzed. Results: The mean age was 53.40 ± 10.25 years. The PTX-3 levels were significantly higher in patients with CAD than without CAD (146.48 ± 48.52 vs. 109.83 ± 49.06 pg/ml, p < 0.001). A statistically significant difference was found among the 3 groups regarding the severity of CAD (165.66 ± 49.10, 127.83 ± 40.51 and 109.83 ± 49.06 pg/ml, p < 0.001, respectively). The serum PTX-3 levels in normal arteries were 110.4 ± 48.11 pg/ml, in single-vessel disease 132.35 ± 32.96 pg/ml, in 2-vessel disease 142.57 ± 55.88 pg/ml, in 3-vessel disease 156.07 ± 50.53 pg/ml, and in 3-vessel disease 160.50 ± 30.41 pg/ml. After adjusting for baseline confounders, older age (OR = 1.107, 95% CI = 1.027-1.193, p = 0.008) and higher PTX-3 levels (OR = 1.017, 95% CI = 1.003-1.032, p = 0.021) were detected as significant predictors for the presence of CAD. Conclusions: Higher PTX-3 levels were associated with the presence of CAD and its increased severity in clinically stable patients. Higher PTX-3 levels may be regarded as a novel diagnostic predictor and may offer therapeutic options in the clinic.
