Classification of pressure ulcer images with logistic regression
Kocaeli University;Kocaeli University Technopark2021 International Conference on INnovations in Intelligent SysTems and Applications, INISTA 2021 -- 25 August 2021 through 27 August 2021 -- -- 172175Pressure ulcers are wounds caused by prolonged lying in bedridden patients. This has become an important health problem in many countries. Correct diagnosis of pressure ulcers is very important for an effective treatment method. The characteristics of these wounds are effective in terms of seeing the healing. Interventional methods of obtaining information in the diagnosis of pressure ulcers are painful for patients. In addition, these methods can increase the risk of infection. Therefore, imaging systems such as nonsurgical wound tracking techniques allow accurate analysis of the features of the wound without contact with it. The aim of this study is to prevent wound formation or to make a positive contribution to the treatment processes by using machine learning techniques in image analysis for the classification of pressure ulcers. In this study, 142 wound images were analyzed by Logistic Regression and Artificial Neural Networks methods. Features such as wound color and size in these images were separated by image processing and the stage of the wound was determined from the images. The 6 stages of pressure ulcers are referenced for classification. © 2021 IEEE.2-s2.0-8511660776
Investigation of temporal bone asymmetry in cases with unilateral tinnitus: morphometric and multicentric clinical study.
The aim of this multicentric study was carried out to compare the anatomical structures of temporal bones in patients with unilateral tinnitus in healthy ears. We also aimed at evaluating whether age- and gender-related asymmetrical changes occur in temporal bones or not. Fifty-two ears of 26 patients who had unilateral tinnitus were included into the retrospective study. The patients who had subjective nonpulsatile tinnitus and who previously had temporal computed tomography according to their file records were accepted to the study. Temporal computed tomography. scans and audiometric results of patients were examined retrospectively. Middle ear volume, diameter of internal acoustic meats, and diameter of jugular bulb were evaluated by both anatomist and radiologist, in an interobserver manner. Internal acoustic meats and jugular bulb were found to be larger in the ears that had tinnitus than in the healthy ears; however, there was no statistical significance. The stereological morphometric study of the correlation with sex of temporal bone asymmetry in humans is of importance for both otolaryngologists and anatomists. These results will contribute to data on middle ear volume, internal acoustic Meats, and jugular bulb sizes. (Folia Morphol 2013; 72, 1: 22-28
