ABSTRACT
Purpose@#Ankle sprains are among the most common musculoskeletal injuries, and many videos have been shared with patients through YouTube. YouTube allows the easy sharing of information, but there are accuracy and reliability issues due to the lack of verification processes for video producers. This study evaluated ankle sprain videos on YouTube and the correlation between the video scores and viewer preferences using “the number of likes and views”. @*Materials and Methods@#For analysis, the words “ankle sprains”, “ankle exercise”, and “ankle rehabilitation” were searched on YouTube. Only videos taken in Korean were analyzed, and videos with less than 10,000 views and for commercial purposes were excluded. For 31 videos, two orthopedic surgeons and one orthopedic resident used one evaluation tool to evaluate the video quality with up to 30 points for subcategories. The scores between each evaluator were then averaged to evaluate the video quality. To reflect the viewer preferences, “the number of likes and views” were analyzed, and the relationship between the video score and “the number of likes and views” of the video was analyzed statistically. @*Results@#The average score for the video was 9.33. The average scores for subcategories were anatomy and symptoms, 0.90; biomechanics and trauma-mechanism, 0.61; imaging quality, 0.95; clinical evaluation and physical examination, 0.61; treatment, 1.41; rehabilitation, 2.39; prevention and after effects, 0.89; and overall video quality, 1.61. The average of “the number of views” was 50,218.35 times, and “the number of likes” was 893.77 times. No correlation was observed between the video scores and “the number of likes and views”. @*Conclusion@#Most videos posted on YouTube did not provide high-quality medical information on ankle sprain, and there was no correlation between the video scores and viewer preferences. This suggests that incorrect medical information is being transmitted to patients, which can be harmful. Therefore, it is necessary to present the latest trend treatment and rehabilitation protocols for ankle sprains in an expert council and promote it through various channels.
ABSTRACT
Calcium pyrophosphate dihydrate (CPPD) crystal deposition disease is characterized by chondrocalcinosis, which mainly affects the knees, wrists, pelvis, and rarely, the spine. According to previous reports, CPPD crystal deposits display heterogeneous enhancement on MRI. When combined with inflammation of the surrounding soft tissue, strong enhancement by CPPD crystal deposition may appear similar to imaging features of other conditions such as infectious spondylitis. In these conditions, CT plays an important role in differential diagnosis. Here, we present a case of CPPD crystal deposition disease in the ligamentum flavum of the cervical spine that showed intense enhancement on MRI.
ABSTRACT
PURPOSE: Poisoning is an important cause of death in Korea. We aimed to investigate the epidemiological characteristics and outcomes for in-hospital cardiac arrest (IHCA) in poisoned patients in Korea. METHODS: This is a population-based study, analyzing 576 IHCA patients who were poisoned and registered in the Korean Health Insurance Review and Assessment Service in 2013. The cardiopulmonary resuscitation outcomes, including survival discharge and 30-day survival rate, were analyzed. The main diagnoses were categorized in accordance with the Korean Standard Classification of Diseases version 6. RESULTS: The overall survival discharge and 30-day survival rate were 31.6% and 15.3%, respectively. The most common etiologies of poisoning were pesticides (54.3%), drugs and medications (21.9%), carbon monoxide (8.9%), and unspecified substances (5.4%); the 30-day survival rate for each etiology was 16.6%, 15.2%, 9.8%, and 19.4%, respectively. A geographical analysis showed a high 30-day survival rate in Gwangju (32.0%), Daejeon (25.0%) and Ulsan (25.0%). CONCLUSION: Pesticides poisoning is the most common cause for IHCA patients. The survival rate after IHCA by poisoning was similar in pesticides poisoning than in other toxic etiologies. Therefore, it is crucial to reduce pesticide poisoning and to establish a poisoning information inquiry system.
