Background and Objectives:
The aim of this study was to confirm the effect of intralesional triamcinolone acetonide injections (TRIAM) to treat granulomatous tissue surrounding the tracheostomy stoma.Subjects and Method We reviewed and documented the medical charts of 20 patients who were administered with TRIAM to treat granulomatous tissue surrounding the tracheostomy stoma from January 2018 to June 2019 were. The surface area of the granulomatous tissue was measured using Image J. The differences between the area of the granulomatous tissue after conventional treatment and after TRIAM on the same patient were compared.
Results:
A total of 20 patients consisting of 12 males and 8 females were included, with the patients’ average age being 60.0±14.3 years. The initial surface area of granulation tissue was 1.266±0.449 cm2, and 1.243±0.432 cm2 after conventional treatment, showing no statistically significant difference in the tissue area (p=0.143). The pre-injection surface area of granulation tissue was 1.243±0.432 cm2, and the area on the 7th day after the third injection was 0.477±0.217 cm2, showing a significant difference (p<0.001).
Conclusion
Compared to the conventional treatment, the surface area of granulomatous tissue surrounding the tracheostomy stoma significantly decreased after being treating with TRIAM. This finding suggests the effectiveness of TRIAM as a treatment of granulomatous tissue surrounding the tracheostomy stoma without complications such as bleeding.

Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules, recurrent thyroid cancers (RTCs), and primary thyroid microcarcinomas. The Korean Society of Thyroid Radiology (KSThR) initially developed recommendations for the optimal use of RFA for thyroid tumors in 2009 and revised them in 2012 and 2017. As new meaningful evidence has accumulated since 2017 and in response to a growing global interest in the use of RFA for treating malignant thyroid lesions, the task force committee members of the KSThR decided to update the guidelines on the use of RFA for the management of RTCs based on a comprehensive analysis of current literature and expert consensus.

Background:
Coronavirus disease 2019 (COVID-19) is a newly emerged infectious disease that needs further clinical investigation. Characterizing the temporal pattern of combined infections in patients with COVID-19 may help clinicians understand the clinical nature of this disease and provide valuable diagnostic and therapeutic guidelines.
Methods:
We retrospectively analyzed COVID-19 patients isolated in four study hospitals in Korea for one year period from May 2021 to April 2022 when the delta and omicron variants were dominant. The temporal characteristics of combined infections based on specific diagnostic tests were analyzed.
Results:
A total of 16,967 COVID-19 patients were screened, 2,432 (14.3%) of whom underwent diagnostic microbiologic tests according to the clinical decision-making, 195 of whom had positive test results, and 0.55% (94/16,967) of whom were ultimately considered to have clinically meaningful combined infections. The median duration for the diagnosis of combined infections was 15 (interquartile range [IQR], 5–25) days after admission. The proportion of community-acquired coinfections (≤ 2 days after admission) was 11.7% (11/94), which included bacteremia (10/94, 10.63%) and tuberculosis (1/94, 1.06%). Combined infections after 2 days of admission were diagnosed at median 16 (IQR, 9–26) days, and included bacteremia (72.3%), fungemia (19.3%), cytomegalovirus (CMV) diseases (8.4%), Pneumocystis jerovecii pneumonia (PJP, 8.4%) and invasive pulmonary aspergillosis (IPA, 4.8%).
Conclusion
Among COVID-19 patients with risk factors for severe complications, 0.55% had laboratory-confirmed combined infections, which included community and nosocomial pathogens in addition to unusual pathogens such as CMV disease, PJP and IPA.

Objective:
Using a nationally representative cohort of medical claims data in Korea, this study aimed to analyze the association between the use of various anti-rheumatic agents and the risk of acute myocardial infarction (AMI) in patients with rheumatoid arthritis (RA).
Methods:
This nested case-control study used the Korean Health Insurance Review and Assessment data of 35,133 patients newly diagnosed with RA between 2011 and 2020. Incident AMI patients were identified and matched at a 1:4 ratio with randomly selected controls. The usage of anti-rheumatic agents was measured from the date of RA diagnosis to the index date and stratified based on exposure time and duration. The risk of AMI associated with each anti-rheumatic agent was estimated using conditional logistic regression, adjusted for comorbidities and concomitant drug use.
Results:
Of the 35,133 patients with RA, 484 were diagnosed with AMI. In total, 484 AMI patients and 1,924 controls with newly diagnosed RA were included in the analysis. Current exposure and long-term exposure to glucocorticoids (adjusted odds ratio [aOR]: 2.301, 95% confidence interval [CI]: 1.741~3.041; aOR: 1.792, 95% CI: 1.378~2.330) and leflunomide (aOR: 1.525, 95% CI: 1.196~1.944; aOR: 1.740, 95% CI: 1.372~2.207) were associated with an increased risk of AMI.
Conclusion
The study demonstrates a significant association between the current and long-term use of glucocorticoids and leflunomide and an increased risk of AMI in patients with RA. These findings underscore the importance of careful consideration of cardiovascular risks when selecting anti-rheumatic agents for RA treatment.

Objective:
To analyze epidemiological trends and changing characteristics of syphilis among students in Yunnan Province from 2005 to 2023, so as to provide evidence for the comprehensive prevention and control of syphilis in schools.
Methods:
The case data of syphilis among students in Yunnan Province from 2005 to 2023 were obtained from the China Information System for Disease Control and Prevention. The Joinpoint regression model was used to conduct a time trend analysis of the reported incidence rate of syphilis.
Results:
From 2005 to 2023, a cumulative total of 3 191 cases of syphilis were reported in schools in Yunnan Province(1 248 male cases and 1 943 female cases). The reported incidence rate rose continuously from 0.17/100 000 in 2005 to 8.26/100 000 in 2023, with an average annual percent change (AAPC) of 24.89%( Z =13.18, P <0.01). The reported incidence rate was higher in female students than in male students ( χ 2=229.48, P <0.05). The incidence rates in the primary school, junior high school, senior high school and higher education were 0.21/100 000, 2.42/100 000, 4.45/100 000 and 6.29/100 000 respectively, and the difference was statistically significant (χ 2=3 432.84, P <0.05). The average annual growth rate was the highest in the junior high school stage(AAPC= 30.68% , Z =7.57, P <0.05),followed by the senior high school stage (AAPC=24.28%, Z = 5.70 , P <0.05).The reported incidence rate of primary and secondary syphilis increased from 0.12/100 000 in 2005 to 2.06/ 100 000 in 2023, with an AAPC of 16.86% ( Z = 4.57, P <0.05).
Conclusions
The overall reported incidence rate of syphilis among students in schools in Yunnan Province shows a sustained upward trend, with the most rapid annual increase observed in junior high schools. Schools should prioritize syphilis education and expand awareness campaigns to curb transmission.

Purpose:
This study aimed to report the results of Korean Antimicrobial Resistance Monitoring System (KARMS) for uncomplicated cystitis (UC) in 2023.
Materials and Methods:
KARMS was established for the surveillance of antimicrobial resistance in urinary tract infections with the cooperation of Korean nationwide medical centers. Data from patients with UC have been collected in the web-based KARMS database. Demographic data, uropathogen distribution, and antimicrobial susceptibility of representative pathogens were analyzed.
Results:
A total of 885 patients’ data were collected in KARMS database. The mean patient age was 56.39±18.26 years. The number of postmenopausal and recurrent cystitis were 530 (61.1%) and 102 (11.5%), respectively. Escherichia coli was the most frequently identified uropathogen (654/871, 75.1%). Regarding antimicrobial susceptibility, 94.9% were susceptible to fosfomycin, 90.5% to nitrofurantoin, 58.4% to ciprofloxacin, 83.6% to cefotaxime, and 100.0% to ertapenem. ESBL positivity was 13.7% (96/702), and significantly higher in tertiary hospital (23.1%, p<0.001), postmenopausal (15.9%, p=0.044), and recurrent cystitis (24.7%, p=0.001).Fluoroquinolone resistance was significantly higher in tertiary hospital (47.4%, p=0.001), postmenopausal (44.9%, p<0.001), and recurrent cystitis (59.8%, p<0.001). In addition, postmenopausal (odds ratio [OR] 1.96, 95% confidence interval [CI] 1.38–2.77, p<0.001) and recurrent cystitis (OR 2.37, 95% CI 1.44–3.92, p=0.001) were associated with increased fluoroquinolone resistance.
Conclusions
These data provide information on the distribution of uropathogen and the status of antimicrobial resistance in UC of South Korea. In addition, KARMS will be a useful reference in the future through the continuous surveillance system construction over the years.

Annals of Hepato-Biliary-Pancreatic Surgery 2025;29(2):140-149
Background:
s/Aims: We compared the postoperative outcomes of single-incision laparoscopic cholecystectomy (SILC) with those of single-incision robotic cholecystectomy (SIRC) using the da Vinci Xi and SP systems.
Methods:
We retrospectively analyzed data from 206 patients who underwent these procedures by a single surgeon between August 2020 and April 2022. Propensity score matching was used to adjust for confounders and evaluate outcomes.
Results:
SILC exhibited shorter operation times compared to SIRC with Xi and SP (44.9 ± 14.5 min vs. 55.3 ± 12.2 min vs. 55.2 ± 16.2 min, p < 0.001). SIRC with Xi had shorter docking times (6.2 ± 2.8 min vs. 10.3 ± 2.3 min, p < 0.001), while SIRC with SP demonstrated reduced console times (11.2 ± 2.4 min vs. 18.6 ± 8.0 min, p < 0.001). Pain scores and complications did not significantly differ between the groups.
Conclusions
Both SILC and SIRC showed comparable outcomes, with the SP system providing advantages such as reduced console time and fully articulated arms, likely reducing surgeon stress.

Annals of Surgical Treatment and Research 2025;108(4):245-255
Purpose:
This study aimed to define an optimal age cutoff for early-onset gastric cancer (EOGC) and compare its characteristics with those of late-onset gastric cancer (LOGC) using nationwide survey data.
Methods:
Using data from a nationwide survey, this comprehensive population-based study analyzed data spanning 3 years (2009, 2014, and 2019). The joinpoint analysis and interrupted time series (ITS) methodology were employed to identify age cutoffs for EOGC based on the sex ratio and tumor histology. Clinicopathologic characteristics and surgical outcomes were compared between the EOGC and LOGC groups.
Results:
The age cutoff for defining EOGC was suggested to be 50 years, supported by joinpoint and ITS analyses. Early gastric cancer was predominantly present in the EOGC and LOGC groups. Patients with EOGC comprised 20.3% of the total study cohort and demonstrated a more advanced disease stage compared to patients with LOGC. However, patients with EOGC underwent more minimally invasive surgeries, experienced shorter hospital stays, and had lower postoperative morbidity and mortality rates.
Conclusion
This study proposes an age of ≤50 years as a criterion for defining EOGC and highlights its features compared to LOGC. Further research using this criterion should guide tailored treatment strategies and improve outcomes for young patients with gastric cancer.
