A new etiological cause for anterior cruciate ligament injury: E-Scooter.

The usage of electric scooters has been popular because it is a cheap and fast transportation method. Its use has increased in recent years because public transportation is less preferred during the covid-19 pandemic and in parallel, the publications reporting e-scooter accidents are increasing. There is no article examining the relationship between e-scooter and anterior cruciate ligament (ACL) injury in current literature. We aim to examine the relationship between e-scooter accidents and ACL injury incidence. Patients over the age of 18 years who applied to our orthopedics outpatient clinic with the diagnosis of ACL injury between January 2019- June 2021 were evaluated. 80 e-scooter accidents resulting with ACL tears were reviewed. The electronic medical records of the patients were reviewed retrospectively. Information about the age, gender, trauma history of the patients, and type of trauma was obtained. Fifty-eight patients had a history of falling while stopping the scooter, and 22 patients had a history of falling after hitting something. Anterior cruciate ligament reconstruction was performed with hamstring tendon grafts in 62(77,5%) of the patients included in the study. 18 (22,5%) patients were followed up with functional physical therapy exercises because they did not want to be operated on. Various bone or soft tissue injuries while using e-scooters have been reported in the literature until now. ACL injury is also seen quite frequently after these traumas, and necessary information and warnings should be given to the users to prevent ACL injuries.

Medical students? knowledge of the disease, frequency of depression, anxiety, stress symptoms, and related factors in the COVID-19 pandemic: A web-based questionnaire

Objective: In this study, it was aimed to determine the level of knowledge of medical students about coronavirus disease 2019 (COVID-19), to investigate the frequency of depression, anxiety, stress symptoms and related factors.Materials and Methods: The study is a cross-sectional study conducted with 904 volunteer medical students. Data were collected with an online questionnaire, including sociodemographic characteristics, knowledge about COVID-19, the Depression, Anxiety, and Stress Scale.Results: Mean age was 21.3 +/- 2.2 years, and 54% of them (n=488) were female. Fifty five percent (n=497) thought that their level of knowledge about COVID-19 was sufficient, and 94.6% (n=846) were concerned about the disruption of their education. Their knowledge level was found to be 15.09 +/- 2.43 points out of 23 points. The depression, anxiety and stress symptoms were found in 64.9%, 70.4% and 34.1% of participants, respectively. The risk of anxiety (OR=0.51, 95%CI=0.94, p=0.020) and depression (OR=0.95, 95%CI=1.15, p=0.025) were higher in women. Those with a high fear of transmitting the COVID-19 infection to their relatives had higher symptoms of depression, anxiety, and stress. (p<0.001).Conclusion: Medical students have a good knowledge level of COVID-19. However, they experience high levels of anxiety, stress and depression symptoms;and concerned about the disruption of their education.

Investigation of the usability of CT in clinical decision making by comparing COVID-19 positive and probable patients diagnosed according to CT imaging findings

Aim: In this study, the usability of thoracic computed tomography (CT) in clinical decision making was investigated by comparing laboratory results of patients with probable and definite coronavirus disease 2019 (COVID-19) diagnosis according to CT imaging features. Material and Methods: Within the scope of this single-center retrospective clinical study, data of possible and definite cases of COVID-19 were scanned from the hospital electronic database and patient files. Laboratory and CT imaging results of the patients were obtained. Patients were divided into two groups as positive and negative according to their CT imaging results, and compared. Results: Of the 995 patients included in the study, 57% (n=567) were male, and the mean age was 45.7±20.2 years. It was found that 65.1% (n=648) of the patients had positive CT. Real-time polymerase chain reaction (RT-PCR) test result was found positive in 22.2% (n=144) of the CT positive patients, and 32.0% (n=111) of the CT negative patients, and it was statistically significant (p<0.001). In the logistic regression analysis, it was determined that C-reactive protein (CRP), lymphocyte count, ferritin, procalcitonin, D-dimer, lactate and RT-PCR were statistically significant with CT positivity. Conclusion: In this study, COVID-19 positive and probable patients were compared according to thoracic CT findings and the usability of CT for clinical decision making was investigated. It has been determined that thorax CT can be used to initiate the treatment of COVID-19 in patients with negative RT-PCR test results but positive CT findings and high biochemical parameters such as CRP, D-dimer, ferritin and lactate.

Perceived stress levels in patients in novel corona virus infection pandemic: prospective single-center study

Aim: In the progression of the diseases, the psychological and stress levels of the patients affect the course of the disease. This situation is also important and should be analyzed in the follow-up of COVID-19 patients. In this study, it was aimed to investigate the stress levels of COVID-19 patients in our hospital isolation services. Materials and Methods: A prospective cross-sectional study is conducted in our isolation services where possible/definite COVID-19 patients older than 18 years old are followed. According to the patients' swap test results, patients are divided into two groups;group 1: COVID-19 possible, and the group 2: COVID-19 definitive groups. The demographic properties of the patients investigated, and the "Perceived Stress Scale", was applied to all groups the day after the swap test results were completed, and the outputs were analyzed.
