AIM: For the last 20 years, various problems caused by internet has brought attention to researchers. People who actively use the Internet can spend 40 to 80 hours per week on a computer or phone. Their sleep patterns, daily life and exercise habits change over time. These changes bring along some illnesses such as back pain, neck pain and carpal tunnel syndrome. Many of these ailments underlie postural disorders. The most common of these postural disorders is increased thoracic kyphosis. Our aim is to determine the effect of internet usage on thoracic kyphosis angle in healthy individuals. MATERIALS AND METHODS: We conducted our study in 322 (K = 152, E = 170) students who were educated at Sakarya University Medical Faculty. Internet usage questionnaire was applied to the participants to measure the level and duration of internet usage. Thoracic kyphosis angle measurement was done with Flexicurve device Statistical comparisons were made using SPSS software. RESULTS: In our study, the kyphosis angles of the participants varied between 21,067 degrees and 49,546 degrees. The average score of the questionnaire on internet usage was 32,508 (slightly dependent), while the average daily internet use was 200 minutes. When the questionnaire scores and kyphosis angle values were compared, the result was statistically significant (p: 0.016). CONCLUSION: It is important to identify and evaluate the negative effects of internet use on our posture. People should pay attention to internet usage times and body postures during use in order to protect their postures during internet use. Otherwise, there will be an increase in thoracic kyphosis angle with serious disorders in the posture.

Background. Persistent symptoms and physiological disorders that occur after the acute phase of COVID-19 disease are collectively referred to as post-acute COVID-19 syndrome (PACS). Objectives. Symptoms that become permanent after the acute phase in individuals with COVID-19 are called PACS. This study aimed to assess the impact of COVID-19 on ...

Introduction: Carotid artery disease may cause severe constriction or complete occlusion in carotid arteries, it may not give any symptoms until it appears. In some people, stroke is the first finding of the disease. One of the most important causes of stroke is carotid artery stenosis and atherosclerosis causes a total of one third of the stroke. Atherosclerosis; It is a specific finding of both coronary and carotid artery disease.The relationship between carotid atherosclerotic diasease and coronary artery disease (CAD) have been in previous reports Aim: In this study, we aimed to show the relationship between the severity of the carotid artery stenosis(CAS) determined by angiography and the anatomical complexity of CAD assessed by SYNTAX Score (SS). Material and Methods: Our study was carried out in accordance with the Declaration of Helsinki Principles by obtaining the ethics committee approval dated 09.06.17 and numbered E.8640. A total of 45 patients with simultaneously carotid and coronary angiography performed were included in our study. SS, a marker of CAD complexity, was determined by dedicated computer software. The patients were divided into two groups according to the classification of SS: low SS (n=33, SS
