Background: The use of electric scooters (e-scooters) continues to increase as a simple, inexpensive means of transport, resulting in a sharp increase in the incidence of scooter-related accidents. No study to date has closely examined the injury extent to the lower leg, joints, and extremities from e-scooter-related accidents. Here, we investigated the epidemiology and injury patterns of such accidents, focusing on injuries to the ankle and foot. Methods: Based on data from a single tertiary hospital’s database, the demographics of 563 patients with scooter-associated injuries were analyzed retrospectively. Among the patients, 229 patients who were injured by e-scooter riding were further investigated. Based on the data, the general demographics of whole scooter-associated injuries and the injury characteristics and fracture cases of the lower leg, ankle, and foot were analyzed. Results: During the 4-year study period, the number of patients injured by e-scooters increased every year. Lower extremities were the most common injury site (67.2%) among riders, whereas injuries to the head and neck (64.3%) were more common in riders of non-electric scooters. Among the lower leg, ankle, and foot injuries of riders (52 cases), the ankle joint (53.8%) was the most commonly injured site, followed by the foot (40.4%) and lower leg (21.2%). The fracture group scored significantly higher on the Abbreviated Injury Scale than the non-fracture group (p < 0.001). Among the fracture group (20 cases), ankle fractures (9 cases) were most common, including pronation external rotation type 4 injuries (4 cases) and pilon fractures (2 cases). Five patients (25%) had open fractures, and 12 patients (60%) underwent surgical treatment. Conclusions The ankle and foot are the most common injury sites in e-scooter-related accidents. Given the high frequency and severity of e-scooter-related ankle and foot injuries, we suggest that more attention be paid to preventing these types of injuries with greater public awareness of the dangers of using e-scooters.

Differentiated thyroid cancer demonstrates a wide range of clinical presentations, from very indolent cases to those with an aggressive prognosis. Therefore, diagnosing and treating each cancer appropriately based on its risk status is important. The Korean Thyroid Association (KTA) has provided and amended the clinical guidelines for thyroid cancer management since 2007. The main changes in this revised 2024 guideline include 1) individualization of surgical extent according to pathological tests and clinical findings, 2) application of active surveillance in low-risk papillary thyroid microcarcinoma, 3) indications for minimally invasive surgery, 4) adoption of World Health Organization pathological diagnostic criteria and definition of terminology in Korean, 5) update on literature evidence of recurrence risk for initial risk stratification, 6) addition of the role of molecular testing, 7) addition of definition of initial risk stratification and targeting thyroid stimulating hormone (TSH) concentrations according to ongoing risk stratification (ORS), 8) addition of treatment of perioperative hypoparathyroidism, 9) update on systemic chemotherapy, and 10) addition of treatment for pediatric patients with thyroid cancer.

The purpose of this study was to explore the variables of foot pressure according to glycated hemoglobin level during walking in diabetic patients with pes rectus. The subjects of this study were 39 people (78 feet) in their 40s and 60s, and they were divided into 11 pre-diabetic patients (22 feet) and 14 diabetic patients (28 feet) based on glycated hemoglobin; 14 patients without diabetes (28 feet) was used as a control. Foot pressure was measured using the EMED-LE Measurement system. The sole of the foot was divided into 12 parts, each of which was analyzed for pressure, force, contact area, and grounding time. For statistics, nonparametric Kruskal–Wallis and Wilcoxon signed rank test were used. Prediabetic and diabetic patients had lower hindfoot and second and third metatarsal foot pressure but higher first and third toe pressure compared to those without diabetes. In addition, the maximum and minimum force were high in all parts of the sole, and the contact time was long, signifying strong downward force for a long duration. Measurement of foot pressure by parts allowed detailed analysis of abnormal foot pressure and is valuable as basic data for diagnosis, prediction, and treatment of diabetic foot. Based on these data, maximum and minimum pressure better explain the problem of plantar pressure distribution rather than mean maximum pressure.

Background: Non-alcoholic fatty liver disease (NAFLD) is the most frequent liver disease. Evidence supporting a strong relationship between psoriasis and NAFLD exists. NAFLD is significantly higher in psoriatic patients than in matched controls and psoriatic patients with NAFLD have more severe forms of psoriasis than those without NAFLD. Objective: To evaluate the prevalence and clinical features of NAFLD among Korean psoriatic patients with abnormal liver function tests. Methods: We evaluated the laboratory results of psoriatic patients who visited the Department of Dermatology, National Medical Center, between September 2012 and June 2017. Those who had abnormal liver function tests were consulted by a hepatologist to confirm the diagnosis of NAFLD using ultrasonography. Results: A total of 307 psoriatic patients underwent liver function tests (LFTs), and 46 patients (15.0%) had abnormal LFT values. A hepatologist consulted psoriatic patients with abnormal LFTs, and hepatic ultrasonography was performed; 34 patients (73.9%) were diagnosed with NAFLD. Among psoriatic patients with abnormal LFTs, those with a Psoriasis Area and Severity Index (PASI) ≥10 had a significantly higher rate of NAFLD than psoriatic patients with PASI ＜10 (87.5% vs 59.1%). Conclusion Among psoriatic patients with abnormal LFTs, 34 patients (73.9%) were diagnosed with NAFLD.Psoriatic patients with PASI ≥10 had a significantly higher rate of NAFLD than those with PASI ＜10.
