Management of post-operative complications during maxillary teeth extraction

Abstract Introduction: During maxillary teeth extractions, variety of complications can occur which can significantly affect the post-operative healing period and patient’s life in general. Aim: The main aim was to discuss some of the most common complications that clinicians encounter during dental extractions and proper management of the potential complications associated with the procedure. Materials and methods: To achieve the aim, variety of materials and methods have been used in order to appropriately manage the complications. The following materials and methods were used: ligature and resorptive sutures in arterial bleeding, ice packs and steroids in post-op swelling, Caldwell – Luc procedure in cases of tooth root in maxillary sinus etc. Results: With the previously noted methods, we have achieved successful control over the complications. For example, use of steroids decreases swelling in post-op day 3-4 to completely disappear by day 10. Conclusion: Several common post-operative complications of dental extractions have been discussed here, and their etiologies and managements explored. It’s our hope that the practitians will be more prepared to manage this kind of complications which often occur in daily practice. Keywords complications, extraction, management, maxillary

Post-operative complications after extraction of impacted lower third molar

Abstract Introduction.Complications that can occur after wisdom tooth extraction can significantly impair quality of life and also prolong the healing period after the extraction. Aim. The main aim was to determine how the surgical removal of impacted lower third molar affects the postoperative healing and qualityof life. Determination of the most common complications that impair healing and quality of life was done. Material and method.To realize the aim, 10 subjects aged were included. In order to observe the most common complications of the subjects were called for checkup. Among subjects check-ups were performed in the first, second, seventh and tenth day after the intervention. During the examination by the subjects noted the presence of pain, bleeding, discomfort, difficulty in opening of the mouth, swelling and redness. Results. The largest number of respondents aged 18-22 years. The most common complications occurred in the first day were postoperative pain, followed by trismus, then postoperative appearance of swelling and finally bleeding. In a study observed that as time passes the number of persons who are present complications decreases. Conclusion. Based on the collected data and subsequent analysis can be concluded that because of the high incidence of complications, they affect the daily life and hence a violation of the quality of life of people. Keywords Impacted lower third molars, quality of life, oral quality of life, postoperative complications

APPLICATION OF DIFFERENTIAL EQUATIONS IN EPIDEMIOLOGICAL MODEL

Mathematical modelling is a tool for presenting objects and processes with mathematical language and mathematical rules. Mathematical models can be used for research in public health and epidemiology. Nowadays, during the COVID19 outbreak, mathematical modelling is playing a central role in controlling the spread of infection, making predictions that can help monitoring the epidemic and making adequate responses, in order to lower the number of new infections. In this paper, several models commonly used to control the spreading of infections are considered. These models can also help controlling the COVID 19 infections

Agent-based Modelling and Simulation

One of the most important methods in the educational process, is modelling and simulation of real-world problems. In many situations it is not possible to experiment with real objects to find the right solutions: building, destroying, and making changes may be too expensive, dangerous, or just impossible. Modelling and simulation can be used to build model to represent the real system. Agent based modelling is a relatively new method compared to system dynamics and discrete event modelling. That are computer simulations used to study the interactions between people, things, places, and time. The agents are programmed to behave and interact with other agents and the environment in certain ways. In this paper, the agent-based modelling simulation is considered. In simulation software Anylogic are given some examples of agent-based modelling

Apache http server as forward proxy server

A server is a specialized computer for running utility software. If we want to protect our data while using Internet, we use a proxy server. In this paper we will talking about proxy server, types of proxy servers and at the end about Apache http serves as forward proxy server. Apache can be also used as reverse proxy server, but that will be discussed in some next paper

Mathematics of the Future: Understanding and Application of Mathematics with the Help of Technology

Knowledge and skills must keep up with the rapid changes in today's world. Basic knowledge and skills of great complexity are crucially important for the inclusion of the citizens as active members of the society. The development of modern society is based on the knowledge and skills acquired during the education process which is important for the individual and for society, in general. FutureMath project is addressed to solve backwardness of technology and pragmatic educational methods of the educational institutions. FutureMath project aims • to improve professional competences and to support innovation in the teachers' system of training through pedagogical solutions and innovative practices based on the new computer and multimedia technologies • to provide tools and methodologies to facilitate the acquisition of the mathematical competence by introducing advanced technological tools in the teaching of Mathematics and its application. • to develop skills which can be used in order to contribute to a cohesive society, in particular to increase opportunities for learning mobility and through strengthened cooperation between the world of education and training and the world of work, formulating and solving complex problems autonomously, consciously and constructively. FutureMath project aims to expand and modernize teaching and learning methods used in the field of mathematics and mathematics-based sciences through modernization of Calculus courses with STEAM principles. Based on the experience of using technology before and during Covid-19 crisis, the project tends to expand the knowledge base and implementations to other mathematics and mathematics-based courses. Multidisciplinary approaches in the development of mathematics courses using STEAM principles will enhance employability and improve students’ career prospects. The participants of the project have great experiences in mathematics education in new technology environment and are willing to use their previous experiences in STEAM to develop STEAM methodology and technology for mathematics course at university level. The participants of the project got experiences in teaching during the Covid-19 period, “stay at home”, and decided to improve distance and face to face learning using STEAM principles. There are five intellectual outputs of project: • Analysis report on state of art in using technologies to support teaching in Mathematics after Covid-19 crisis. • Development of new STEAM methodology and technology • FutureMATH video collection • Piloting lessons and testing • Analysis and further developmen

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
