Title: Huge Nasopalatine Duct Cyst Treated by Transnasal Endoscopic Marsupialization: A Case Report and Literature Review Authors: Kim, Su-Jong; Moon, Jee Won; Lee, Heung-Man Abstract: Nasopalatine duct cyst (NPDC) is the most common nonodontogenic cyst originating from the epithelial remnants of the incisive canal in the maxilla. NPDC is treated with complete enucleation via a sublabial or transpalatal approach, and recently tranasnasal endoscopic marsupialization has been gradually used. However, in large and extensive cases, it is difficult to remove the cyst completely, and there is a high risk of postoperative complications, including oronasal fistula. Therefore, tranasnasal endoscopic marsupialization is recommended as an effective treatment modality. Herein, we report a case of a 49-year-old man with a very large NPDC with a maximum diameter of 58 mm. NPDC was successfully managed by transnasal endoscopic marsupialization under general anesthesia without any major problems. No postoperative complications or recurrence occurred until 12 months postoperatively. Transnasal endoscopic marsupialization for large NPDC is minimally invasive and useful.

Title: School Nurses' Experiences and Needs in COVID-19 Pandemic Response: A Qualitative Study Authors: Seo, Kyoungsan; Kim, Se-an; Choe, Young June; Moon, Jihyun Abstract: The coronavirus disease 2019 pandemic drastically shifted the public health burden onto the school health system. We, therefore, explored the school nurses' experiences and needs for confronting the pandemic in school settings across Korea. This qualitative investigation enrolled 30 participants after their written consent. A written interview conducted through email and focus group interviews using an online meeting application verified participants' opinions and experiences. Collected data were subjected to text-mining and content analysis. The school nurse was found to be responsible for many tasks, including education on preventive measures with unclear quarantine guidelines. Content analysis identified three key themes: "aggravated difficulties owing to lack of support resulted in burnout," "reflection on supportive resources; direct provisions were helpful," and "needs and suggestions to safeguard students' health in the event of another pandemic." Recommendations should all be considered to keep schools and students safe from future pandemics.

Title: Unravelling interobserver variability in gastrointestinal glandular neoplasia: a contemporary study of US and Korean pathologists Authors: Pacheco, Richard R.; Kim, Hyunki; Choi, Won-Tak; Kook, Myeong-Cherl; Cho, Mee-Yon; Karamchandani, Dipti M.; Lee, Michael J.; Kim, Baek-Hui; Lee, Sung-Hak; Yang, Zhaohai; Kim, Jihun; Lagana, Stephen M.; Lee, Hwajeong Abstract: AimsInterobserver variability in the assessment of gastric neoplasia biopsies between most Western and Eastern (predominantly represented by Japanese in the literature) pathologists has been documented. It is unknown if such variability exists between the US and Korean pathologists in the current era.MethodsTen gastrointestinal (GI) pathologists from the USA (n=5) and South Korea (n=5) evaluated 100 scanned images of gastric (n=50) and colorectal (n=50) neoplasia biopsies and answered multiple questionnaires. Consensus was defined as the answer chosen by the majority. Cohen's (& kappa;c) and Fleiss' kappa (& kappa;f) values were calculated between the consensus of the two groups and among the raters, respectively.ResultsBoth groups reached a consensus in the majority of cases (74%-100%) with slight to perfect intergroup (& kappa;c=0.049-1.000) and no to substantial intragroup (& kappa;f=-0.083 to 0.660) agreements. For gastric neoplasia, Korean pathologists relied heavily on cytoarchitectural atypia, whereas the US pathologists focused on stromal invasion when diagnosing adenocarcinoma. For colorectal neoplasia, the Korean pathologists identified concurrent intramucosal carcinoma when diagnosing invasive adenocarcinoma, while the presence of desmoplasia was a prerequisite for the diagnosis of invasive adenocarcinoma for the US pathologists.ConclusionsFor GI neoplasia biopsy interpretation, the diagnostic approach of Korean pathologists is similar to that of Eastern/Japanese pathologists. Consensus outperformed kappa statistics in capturing the magnitude of inter-rater and intergroup reliability, highlighting the potential benefit of consensus meetings to decrease the gap between Western and Eastern diagnostic approaches.

Title: Circulating Vitamin D Levels in Patients With Systemic Sclerosis: a Meta-Analysis Authors: Lee, Young Ho; Song, Gwan Gyu Abstract: Objective This study aimed to evaluate the relationship between circulating vitamin D levels and systemic sclerosis and to establish an association between vitamin D deficiency and systemic sclerosis.Methods We performed a meta-analysis comparing the plasma/serum vitamin D levels and vitamin D deficiency between patients with systemic sclerosis and healthy controls and examined correlation coefficients between circulating vitamin D levels and the Rodnan score.Results Twenty-one studies involving 1,399 patients with systemic sclerosis and 1,311 controls were included. The systemic sclerosis group had significantly lower vitamin D levels than the control group. Stratification by ethnicity demonstrated significantly decreased vitamin D levels in patients with systemic sclerosis among European, Asian, Arab, Latin American, and mixed populations. Stratification by age, sex, and/or body mass index revealed significantly lower vitamin D levels in the systemic sclerosis group regardless of the adjustment. Subgroup analysis by sample size revealed significantly lower vitamin D levels in the systemic sclerosis group by small (n<100) and large sample numbers (n>100). Stratification by publication year revealed significantly lower vitamin D levels in the systemic sclerosis group in both recent and old publication years. However, no significant difference in vitamin D levels was observed between diffuse and limited types of systemic sclerosis. Vitamin D deficiency was significantly associated with systemic sclerosis. The meta-analysis of correlation coefficients revealed a tendency of inverse correlation between circulating vitamin D levels and the Rodnan score.Conclusions Patients with systemic sclerosis had lower circulating vitamin D levels and higher vitamin D deficiency and there was a tendency of inverse correlation between circulating vitamin D levels and the Rodnan score.
