The purpose of this article is to analyse the facial nerve electrophysiological monitoring effective ness in preventing injuries of this nerve during parotid surgery. To achieve this goal we analysed relevant data available in the literature on both the surgical technique and intraoperative continuous monitoring principles. In order to draw the conclusions of this paper we correlated the obtained data with our own experience.
Abstract:Healthcare sector provides huge volume of data on patients and their illnesses, on health insurance plants, medication and treatment schedules for different diseases, on medical services and so forth. Nowadays, there is a growing demand for the healthcare community to transform the existing quantities of healthcare data into value-added data, by discovering unknown patterns and relations between these data and by using them in the decision-making process, even if they refer to management, planning or treatments. Data mining consists in discovering knowledge and techniques such as classification and regression trees, logistic regression and neural networks that are adequate to predict the health status of a patient, by taking into account various medical parameters (also known as attributes) and demographic parameters. This paper presents a case study on the classification of patients with thyroid dysfunctions into three classes (i.e. 1 -hypothyroidism, 2 -hyperthyroidism, 3-normal) by using data mining algorithms and discusses possible methods to improve the accuracy of the considered classification models.
Transnasal endoscopic dacryocystorhinostomy is a good alternative for external DCR. It is considered a safe and efficient technique with successful results, comparable or even better than the external technique. Advanced knowledge of the endoscopic anatomy and the lacrimal system is necessary to perform the procedure safely, and to obtain good surgical outcomes. The aim of the paper is to analyze the changes of the endoscopic technique and to improve it. The transnasal endoscopic dacryocystorhinostomy surgical technique is described in a "step by step" manner. Also the surgical technologies that can be used for this intervention are presented, focusing on the cold instruments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
