This study aimed to establish infection control strategies for preventing the spread of scabies within a single institution by analyzing the epidemiological characteristics of patients diagnosed with scabies. Methods: This was a retrospective descriptive study. The electronic medical records of 430 patients diagnosed with scabies at the dermatology outpatient department of Uijeongbu St. Mary’s Hospital from January 2020 to December 2022 were used to collect data on their characteristics. The subjects were divided into three groups: patients, family of confirmed patients, and healthcare workers. General and epidemiological characteristics were analyzed. Results: The average age was 60.89 ± 22.39 years. The number of days from symptom onset to diagnosis was unknown in many cases (65.3%), although the average was 63.42 ± 64.18 days. Repeated visits after treatment were observed in 193 patients (67.5%), 38 family members of confirmed patients (55.1%), and 35 healthcare workers (46.7%), showing a statistically significant difference (p = .002). The most common place of residence before the visit was home (56.2%), and the most common suspected origin of contagion was the home (38.3%), and the most common category of the suspected contagious person was family (49.6%). Conclusion: Cases of scabies were disproportionately common in women and older adults. The interval from symptom onset to diagnosis was long, and about half of the cases involved itching but no skin lesions. More than one-thirds of cases did not revisit for a follow-up after 2 weeks. In the overall results, unlike previous studies, factors related to home and family were frequently observed as epidemiological characteristics.

Objective: Although controversial, there is a consensus that regional trauma centers have survival benefits over nonregional trauma centers. In a predominantly rural province with a single regional trauma center, this study compared the inhospital mortality of all trauma patients and severely injured patients between regional and non-regional trauma centers. Methods: Using the data from the National Emergency Department Information System in Korea, this study examined all trauma patients who visited emergency departments in Gangwon Province between January 2015 and December 2017. The International Classification of Disease-Based Injury Severity Score (ICISS) was used to categorize the severity of the patients. Propensity score matching was used to balance the severity between the two groups. Results: Of 23,510 trauma patients, 2,857 and 20,653 were treated in regional and non-regional trauma centers, respectively. After propensity score matching, all patients in the non-regional trauma center group had a 6.27-fold higher risk of mortality than those in the regional trauma center group; severely injured patients, which were defined as those with ICISS <0.9, in the non-regional trauma center group had a 4.90-fold higher risk of mortality than those in the regional trauma center group. The ICISS cutoff values for mortality were 0.9015 and 0.8737 for the non-regional and regional trauma center groups, respectively. Conclusion The conventional paradigms of trauma systems can be used in predominantly rural Korean provinces, because trauma care has better survival benefits in regional trauma centers than in non-regional trauma centers. In addition, severely injured patients should be transported to regional trauma centers from the trauma scene.

Objectives: To compare presurgical skeletal factors and postsurgical relapse patterns between more relapsed (MR) and less relapsed (LR) groups. Materials and Methods: This study retrospectively examined patients who underwent mandibular setback surgery, classifying them into two groups based on the amount of relapse of the pogonion using K-means analysis. Comparisons were conducted by analyzing cephalometric radiographs presurgically (T0), at 1-month post-surgery (T1), and immediately after orthodontic treatment (T2). Results: The MR group at T0 had a lower articular angle and AB to the mandibular plane angle (MPA), higher gonial angle, shorter anterior and posterior facial heights, and shorter Frankfort horizontal plane to the upper incisor and first molar. The articular angle in the MR group increased postoperatively. The Frankfort MPA (FMA) did not differ significantly between the MR and LR groups. Conclusion Acute articular angle and short facial height with a high gonial angle in the presurgical stage can predict surgical relapse regardless of the FMA.

Prolonged skin inflammation is caused by disrupted skin barrier resulting in chronic inflammatory diseases such as atopic dermatitis. As a potent natural product with anti-inflammatory property, Aster glehni (A. glehni) is a traditional edible herb and has been used to treat diabetes or colitis-associated colon cancer. In present study, we figured out an additional effect of A. glehni ethanol extract (AGE) in pro-inflammatory cytokines-stimulated human keratinocytes. Mixture of tumor necrosis factor-alpha (TNF-α) and interferongamma (IFN-γ) was used to induce inflammatory responses in the HaCaT keratinocytes. AGE suppressed activation of ERK mitogen-activated protein kinase, nuclear factor (NF)-κB, and signal transducer and activator of transcription 1 and 3 (STAT1 and STAT3). The treatment of AGE inhibited mRNA expressions of proinflammatory cytokines in TNF-α and IFN-γ-stimulated HaCaT cells. Also, AGE induced up-regulated expressions of skin barrier molecules like filaggrin, loricrin, or ZO-1. We evaluated the effects of AGE on protein or mRNA expression levels using western blot or qRT-PCR, respectively. Taken together, these results suggest that the treatment of AGE exerts anti-inflammatory effect on keratinocytes through suppressing inflammatory signaling pathways and up-regulating skin molecules in HaCaT keratinocytes.
