The keratocystic odontogenic tumour (KCOT) is a relatively common oral and maxillofacial lesion that derives from remnants of the dental lamina. It is aggressive, grows rapidly and invades the surrounding tissues. Various treatment modalities and differing recurrence rates have been reported for KCOT. In order to treat a 24-year-old male patient with KCOT the first stage was marsupialisation. This was followed six months later by enucleation with the application of Carnoy's solution. The defect was filled completely with newly formed bone tissue after two years. This case shows that a large KCOT can be treated with a combination of conservative and aggressive methods. Source

Aim: This study was conducted to determine the effect of intradialytic food intake on the urea reduction rate (URR) and single-pool Kt/V (spKt/V) values in hemodialysis (HD) patients. Materials and methods: The study was designed as a quasiexperiment. Twenty-five patients were enrolled in this study. The patients' mean age was 56.5 ± 13.0 years and median time on HD was 63 months. In the first stage of the study, patients were given a standard meal after the first hour of the treatment. The same study group underwent HD without intradialytic food intake 1 week later. Predialysis and postdialysis blood samples for measurement of blood urea nitrogen levels were drawn at the HD sessions with and without food intake. The URR and spKt/V values were calculated. Descriptive statistics, the paired samples t-test, repeated measures analysis of variance, and power analysis were used for the analysis of data. Results: The mean URR and spKt/V values of the patients were higher in the session without food ingestion compared to the other session. Statistically significant differences were found between the sessions with and without food intake for URR and spKt/V values (P < 0.001). Conclusion: Intradialytic food intake seems to cause a decrease in the URR and spKt/V values. © Tübi̇tak. Source

In this study, an efficient algorithm is proposed for the automatic detection of K-complex from EEG recordings. First, the morphology of the K-complex had been examined and the detection features were determined according to visual recognition criterions of human scorer. These features were based on amplitude and duration properties of K-complex waveform. The algorithm is based on wavelet and teager energy operator and includes two main stages. Both results of stages were combined to make robust decision. The EEG recordings obtained from the Sleep Research Laboratory in Department of Psychiatry at Gulhane Military Medical Academy. All night sleep EEG data, total 1045 epochs and 690 of these are NREM 2 stage, from 25 years old healthy female subject were used. Three scorers inspected recording separately to score K-complexes. The detection algorithm was then tested on the same recording. The results show that the agreements between the scorers were fairly different. The results are evaluated with the ROC analysis which proves up to 91% success in detecting the K-complex. © 2011 Elsevier Ltd. All rights reserved. Source

Fingers as organs of manipulation have an important role in function and aesthetics. Moreover, for the majority of patients, the loss of the finger can lead to psychological problems. This case report presents the use of osseointegrated dental implants for the retention of finger prostheses. The possibility of using osseointegrated implant-retained prostheses offers a real alternative for the reconstruction of fingers in cases where other techniques are not applicable. Source

Background The pathogenesis of nonalcoholic fatty liver disease has not been fully elucidated. The most widely supported theory implicates insulin resistance as the key mechanism leading to hepatic steatosis, and perhaps also to steatohepatitis. Also one of causes of NAFLD is central congestion and hepatic injury. RBBB can associated with right ventricular dissynchrony that lead to minimal congestion in liver. So the aim of this study was to test the hypothesis that RBBB as diagnosed by ECG predicts subsequent NAFLD as diagnosed by ultrasonography (the most widely used imaging test for diagnosing hepatic steatosis). Materials and methods Between March 2012 and March 2013, 2200 male subjects underwent electrocardiography (ECG) at our Medical Check-up Center for general young health screening. Of them, 220 subjects had RBBB. All analyses were performed using statistical package SPSS 15.0 and statistical significance was assessed at the two-tailed 0.05 threshold. Results Among the 2200 subjects evaluated, 220 had RBBB. The mean age, BMI, triglycerides, hemoglobin, and aspartate aminotransferase level, the mean HDL cholesterol, alanine aminotransferase, platelet count, %VC, and FEV1/FVC were not different between two groups. The group with RBBB had 66 subjects with NAFLD (30%). The group without RBBB had 44 subjects with NAFLD (2.2%). There were significant differences between the two groups(p < 0.001). Conclusion RBBB is associated with an increased risk of NAFLD in young healthy individuals © 2013 Elsevier Ireland Ltd. Source
