Purpose: To report a nationwide survey on neuroblastoma conducted by the Korean Association of Pediatric Surgeons (KAPS) in 2020. Methods: The clinical data of pediatric patients diagnosed with and treated for neuroblastoma from 2005 to 2019 in 19 hospitals of KAPS members were collected. Survival and prognostic factor analyses were performed using the log rank test and Cox proportional hazard analysis. A p-value <0.05 was considered significant. Results: A total of 669 patients with neuroblastoma were registered for the study. The results were presented and discussed at the 36th annual meeting of the KAPS, which was held in Seoul on August 21, 2020. Conclusion This study provides information on patient demographics, prognostic outcomes, and comprehensive treatment outcomes for neuroblastoma. The study is expected to be an important reference for improving pediatric surgeons’ understanding and treatment of neuroblastoma.

Purpose: Biliary atresia (BA) is a rare but progressive cholangiopathy and the leading cause of pediatric liver transplantation worldwide. The Korean Association of Pediatric Surgeons (KAPS) has conducted three national surveys (2001, 2011, and 2023) to assess long-term trends in the diagnosis, treatment, and outcomes of BA. This study provides a comparative analysis of the 2nd and 3rd national surveys, with reference to selected findings from the 1st survey. Methods: This study included 453 patients from the 3rd national survey (2011–2021) and 435 patients from the 2nd survey (2001–2010), all of whom underwent Kasai portoenterostomy. Data were collected via electronic case report forms from pediatric surgical centers nationwide. Comparisons were made regarding demographics, clinical features, diagnostic patterns, operative details, follow-up outcomes, and survival. Kaplan–Meier analysis was used to evaluate long-term survival. Results: The mean number of BA patients per year remained stable between surveys (43.5 in the 2nd, 41.18 in the 3rd), though centralization of care increased, with 61.5% of cases managed by two major institutions in the 3rd survey. The median age at surgery decreased, and the use of preoperative imaging (especially magnetic resonance cholangiopancreatography) increased. The 10-year native liver survival rate declined from 59.8% to 53.7%, while overall 10-year survival improved slightly (92.9% to 93.2%). Postoperative complications, such as cholangitis and liver failure, persisted but were better categorized. The 3rd survey also reported improved mortality (4.9%) and reduced follow-up loss (11.5%) compared to the 2nd survey. Conclusion While overall survival after Kasai operation has remained high and even improved, native liver survival has slightly declined. The findings reflect earlier diagnosis, more consistent diagnostic imaging, and increasing centralization of care. These trends underscore the importance of long-term nationwide data collection in guiding future strategies for BA management in Korea.

Background: Self-rated oral health is a key indicator of clinical oral conditions and psychosocial factors. Allergic rhinitis, aprevalent chronic respiratory condition, may influence oral health through physiological and behavioral mechanisms. However, its effect on the perceived oral health of adults remain underexplored. This study examined the association between allergic rhinitis and self-rated oral health in a nationally representative Korean adult sample. Methods: Data from the 7th to 9th Korea National Health and Nutrition Examination Surveys (2016∼2019, 2022) were analyzed, excluding 2020∼2021 (coronavirus disease 2019-related data disruptions). The study included 24,056 adults, aged ≥19 years.Allergic rhinitis status was defined based on self-reported diagnoses corroborated by objective testing. Self-rated oral health was dichotomized as “good” or “poor”. Complex sample cross-tabulations and logistic regression analyses were conducted after adjusting for sociodemographic and health-related covariates. Results: Of the participants, 17.2% reported having allergic rhinitis and 34.6% rated their oral health as poor. A greater proportionof adults with allergic rhinitis reported poor self-rated oral health (52.1%) than those without allergic rhinitis. In the unadjusted model, allergic rhinitis was significantly associated with poor self-rated oral health (odds ratio [OR] 1.423; 95% confidence interval [CI] 1.307∼1.549; p＜0.001). This association remained significant after adjustment (OR 1.122; 95% CI 1.011∼1.245; p=0.031). Conclusion Allergic rhinitis is associated with an increased likelihood of poor self-rated oral health among Korean adults. Thesefindings highlight the need for integrated health strategies that consider chronic respiratory conditions when developing oral health promotion programs.

Objectives: This study compares and analyzes the effects of objective body mass index (BMI) and subjective body image on self-perceived oral health among Korean adults based on sex differences. Methods: Raw data were obtained from the 7th (2016-2018), 8th (2019), and 9th (2022) Korea National Health and Nutrition Examination Surveys. The study included 24,817 adults, with objective body type and subjective body image as the independent variables and self-perceived oral health status as the dependent variable. The results were analyzed by sex using complex sample logistic regression analysis with IBM SPSS Statistics. Results: An analysis of the impact of objective body type on poor self-perceived oral health status showed no significant difference for males, whereas the odds ratio was significant for females, with objective obesity at 1.167 (P<0.001). An analysis of the effect of subjective body image on poor self-perceived oral health status revealed that the odds ratio was significant for males with subjective obesity (OR 1.482, P<0.001). For females, the odds ratio was 1.225 for subjective overweight and 1.379 for subjective obesity, indicating that females were significantly more likely to perceive their oral health as poor (P<0.001). Conclusions Both males and females were more influenced by subjective body image than objective body type, and females were more sensitive than males to the impact of body type on their self-perceived oral health status. Although males were generally less sensitive about their body type, they were more likely than females to perceive their oral health negatively.

Objectives: This study aimed to investigate the current status of periodontal disease programs implemented by public health centers in the Republic of Korea. Methods: An explanatory survey was conducted by the Ministry of Health and Welfare from October to November 2023. The survey focused on the periodontal programs and the implementation status across different stages. Distributed and collected via Google Forms, the survey targeted 196 oral health teams within public health centers in Korea. A total of 109 public health centers responded to the study questionnaire, yielding a participation rate of 55.6%. Data were analyzed using IBM SPSS Statistics for Windows, version 26. Results: A majority of periodontal disease programs were implemented exclusively by oral health teams, with a rate of 33.0%. The implementation rate of collaboration with home-visiting health teams was 17.4% and with other teams was 10.1%. The implementation rates of periodontal management across stages were as follows: 11.9% for periodontal examination, 18.3% for periodontal treatment, and 11.9% for sustainable periodontal care. Conclusions Periodontal disease programs are predominantly conducted by oral health teams with limited collaboration across other health teams. Additionally, periodontal management activities, such as examinations and treatments, remain insufficient. Integration between oral health teams and other health teams within public health centers or private dental clinics should be improved.

Objectives: The landscape of work environments has undergone rapid transformation in the wake of the COVID-19 pandemic. This study aims to identify oral health issues among mobile platform workers, analyze the risk factors within their working environment, and promote their oral health. Methods: A purposive sampling approach was employed to select fifteen participants, including replacement drivers, delivery drivers, and delivery couriers/messengers operating within Seoul’s mobile platform workforce. In-depth interviews were conducted between August and November 2023, with all sessions recorded and transcribed. Utilizing grounded theory methodology, data analysis progressed through stages of open coding, axial coding, and selective coding, ultimately leading to the construction of a paradigm model. Results: The majority of participants were male (93.3%), with an average age of 58.7 years. The paradigm model revealed low tooth brushing rates among mobile platform workers. This phenomenon was attributed to a poor brushing environment and a lack of willingness to brush, with the related context being the poor working environment. Intervention conditions included support for tooth brushing, oral health education, and oral examinations. Implementing an action-interaction strategy, which involves problem-solving pathways and a strong motivation to improve, resulted in improved tooth brushing rates. Conclusions To promote the oral health of mobile platform workers, it is essential to improve the environment for tooth brushing, particularly by increasing the availability of restrooms and related facilities as brushing spaces. Additionally, It is necessary to develop oral health policies and implement interventions based on an understanding of the working environment of mobile platform workers.
