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.

Purpose: This paper reports the surgical treatment results of open calcaneal fractures performed at the author’s clinics focusing on open calcaneal fractures to help understand the appropriate treatment and realistic outcomes. Materials and Methods: This study was conducted on 22 cases out of 30 patients who visited the hospital from February 2009 to December 2019 and were followed up for more than one year. In open fractures, the fracture was classified using the Gustilo-Anderson classification and was evaluated using the soft tissue status at the time of visit. Intra-articular calcaneal fractures were classified using Sanders classification. The radiological parameters were measured for the Böhler angle, Gissane angle, calcaneal length, height, and width before and after surgery, and at the last follow-up. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and investigated complications. In addition, statistical analysis of the incidence and associated factors of posttraumatic arthritis was conducted. Results: In all cases, the surgical treatment was performed by minimally invasive surgery. The AOFAS ankle-hindfoot scale conducted for a clinical evaluation of the final follow-up was averaged 72.5 points. In the classification of open fractures, the Gustilo-Anderson classification type IIIA was the most common, and the Sanders type III was the most common. Of the 22 cases after surgery, 15 cases had complications, 11 cases had posttraumatic arthritis, eight cases had an infection, and 4 cases had both complications. Only the Sanders classification showed a statistically significant correlation with the incidence of posttraumatic osteoarthritis (p-value 0.032). Conclusion In treating open calcaneal fractures, internal fixation by a minimally invasive approach showed relatively satisfactory results. However, follow-up research will be needed, including the results of a long-term follow-up through a large number of cases and comparative studies with other surgical methods.

Objectives: The purpose of this study was to explore the effectiveness of the STEAM (Science, Technology, Engineering, Arts, and Mathematics) education program on the use of specific food groups in improving nutrition-related knowledge and attitude, dietary behavior, creative problem solving, and STEAM attitude. Methods: We selected two classes at a kindergarten in Jeollabuk-do, South Korea. A total of 44 kindergarteners from the two classrooms participated in this study. The experimental group and the control group were formed with 22 students each. The experimental group attended 11 STEAM classes on the use of the grain, fruit, and milk food groups. First, we performed the paired t-test to examine changes from pre-to-post classes for both groups.Then, we used ANCOVA to compare post-test scores between the experimental and control groups with the adjustment of pre-test scores. Results: The results demonstrate that the STEAM education program on the use of the food groups significantly improved (1) nutrition-related knowledge and attitude, and dietary behavior (P < 0.001), (2) creative problem solving (P < 0.001), and (3) STEAM attitude (P < 0.001) in the intervention group when compared with the control group. Conclusions The STEAM education program on the use of food groups is effective in enhancing nutrition knowledge and attitude, dietary behavior, creative problem solving, and STEAM attitudes among kindergarten students.

Purpose: The calculation of the intraperitoneal organ surface area is important for understanding their anatomical structure and for conducting basic and clinical studies on diseases related to the peritoneum. To measure the intraperitoneal surface area in a living body by applying artificial intelligence (AI) techniques to the abdominal cavity using computed tomography and to prepare clinical indicators for application to the abdominal cavity. Methods: Computed tomography images of ten adult males and females with a healthy body mass index and ten adults diagnosed with colon cancer were analyzed to determine the peritoneal and intraperitoneal surface areas of the organs. The peritoneal surface was segmented and three-dimensionally modeled using AI medical imaging software. In addition to manual work, three-dimensional editing, filtering, and connectivity checks were performed to improve work efficiency and accuracy. The colon and small intestine surface areas were calculated using the mean length and diameter. The abdominal cavity surface area was defined as the sum of the intraperitoneal area and the surface areas of each organ. Results: The mean peritoneal surface area of all participants was measured as 10,039 ± 241 cm2 (males 10,224 ± 171 cm2 and females 9,854 ± 134 cm2). Males had a 3.7% larger peritoneal surface area than females, with a statistically significant difference (P < 0.001). Conclusion The abdominal cavity surface area can be measured using AI techniques and is expected to be used as basic data for clinical applications.

Purpose: Studies on the appropriate amount of anti-adhesive agents for preventing postoperative adhesion are lacking. This animal study aimed to investigate the distribution of an anti-adhesive agent in the abdominal cavity and estimate the necessary amount to cover the entire cavity. Methods: Fluorescent dye Flamma-552 was conjugated to Guardix-sol to create Guardix-Flamma, which was laparoscopically applied to the abdominal cavity of two 10-kg pigs in different amounts: 15 mL for G1 and 35 mL for G2. After 24 hours, the distribution of Guardix-Flamma was examined under the near-infrared mode of the laparoscope, and the thickness was measured in tissues from the omentum, small, and large intestine by immunohistochemistry. Results: The average area of the abdominal cavity in 10 kg pigs was 2,755 cm2. Guardix-Flamma fluorescence was detected in the greater omentum, ascites in the pelvis, and right quadrant area in G1, whereas in G2, it was detected everywhere. On average, the total thickness of G1 and G2 were 12.68 ± 9.80 μm and 18.16 ± 15.57 μm, respectively. Guardix-Flamma thickness applied to the omentum, small, and large intestines of G2 were 1.31-, 1.45-, and 1.49-times thicker than those of G1, respectively, and were all statistically significant (P < 0.05). Conclusion The entire abdominal cavity of the 10 kg pig was not evenly covered with 15 mL of Guardix. Although 35 mL of Guardix is sufficient to cover the same area with an average thickness of 18 µm, further studies should evaluate the minimum thickness required for an effective anti-adhesive function.

Primary malignant lymphoma of the urinary bladder is a rare disease, and it accounts for only 0.2% of all the cases of extranodal lymphoma. The prognosis of primary bladder lymphoma has been favorable, with many patients being alive and well several years after treatment. We report here on a case of primary diffuse large B cell lymphoma of the urinary bladder in a 75-year-old man patient who presented with a one-month history of persistent dysuria. The abdominal CT revealed a mass at the posterior wall of the urinary bladder. The tissue obtained by transurethral cystoscopy showed an atypical lymphoid proliferation, which was consistent with diffuse large B cell lymphoma. The patient received systemic chemotherapy of rituximab and CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone) and he achieved a significant partial remission.

OBJECTIVE: To investigate the risk factors for symptomatic knee osteoarthritis (OA) in Koreans METHODS: A total of 1,194 persons consisting of 588 men and 606 women (mean age+/-SD, 48.9+/-14.0 years) were enrolled in rural and urban areas or in a hospital of Korea between september 2000 and august 2001. All participants were interviewed about symptoms of knee OA and possible risk factors including age, sex, occupation, body mass index (BMI), smoking, age of menarche, menopause and hormone replacement therapy and examined. Knee radiograph was obtained in all participants with knee symptoms. Symptomatic knee OA was defined according to clinical criteria or clinical and radiographic criteria for classification of osteoarthritis of the knee by Altman. RESULTS: Of 1,194 participants, symptomatic knee OA was found in 189 persons (15.8%) and multivariate analysis showed that female (OR=5.66, 95% CI 3.42~9.38), aging (OR=1.10, 95% CI 1.08~1.12), living in rural area (OR=3.83, 95% CI 2.27~6.45) and BMI over 25 kg/m(2) (OR=2.26, 95% CI 1.42~3.59) were risk factors. Age (older than 70 years, OR=1.08, 95% CI 1.04~1.12) and living in rural area (OR=5.39, 05% CI 1.94~14.96) were associated with symptomatic knee OA in men and age (older than 40 years, OR=1.11, 95% CI 1.07~1.16), living in rural area (OR=2.46, 95% CI 1.17~5.17), and BMI over 25 kg/m(2) (OR=3.45, 95% CI 1.63~7.29) in women. CONCLUSION: The risk factors for symptomatic knee OA were aging, female, living in rural area and high BMI in Koreans.
