Journal of the Korean Dysphagia Society 2024;14(Supple):126-135
Objective:
This study was conducted to investigate the prevalence, status, severity, frequency, and impact on life of drooling in children with cerebral palsy.
Methods:
A total of 74 children with cerebral palsy, aged 2-6 years (53.68±17.33 months), who exhibited drooling symptoms were assessed using the Drooling Severity and Frequency Scale (DSFS) and the Drooling Impact Scale (DIS) to determine the status, severity, frequency, and impact of drooling in drooling group and control group. The study also examined differences in drooling-related factors based on gender, age, and prematurity status.
Results:
The overall prevalence of drooling was 60.8%, 35.6% in those with spastic quadriplegia, and 77.8% in children at Gross Motor Function Classification System (GMFCS) level III-V. Significant differences were found in drooling severity based on gender, prematurity, and age. Higher scores were observed for drooling severity and frequency, frequency of wiping the mouth, and the impact of drooling on the child’s life compare to control group.Although a few had undergone drooling-related treatments, many parents expressed a desire to receive treatment. It was reported that treatment for drooling was primarily provided by occupational therapists through referrals to rehabilitation medicine, with dysphagia rehabilitation and oral motor therapy being the main interventions.
Conclusion
By utilizing standardized assessment tools, the severity of drooling according to the specific conditions of children with disabilities was assessed. It is believed that the necessary steps to be taken include identifying the cause of drooling and setting appropriate treatment goals, followed by the provision for a suitable intervention.

Cancer Research and Treatment 2024;56(1):81-91
Purpose:
Recently, we developed allele-discriminating priming system (ADPS) technology. This method increases the sensitivity of conventional quantitative polymerase chain reaction up to 100 folds, with limit of detection, 0.01%, with reinforced specificity. This prospective study aimed to develop and validate the accuracy of ADPS epidermal growth factor receptor (EGFR) Mutation Test Kit using clinical specimens.
Materials and Methods:
In total 189 formalin-fixed paraffin-embedded tumor tissues resected from patients with non–small cell lung cancer were used to perform a comparative evaluation of the ADPS EGFR Mutation Test Kit versus the cobas EGFR Mutation Test v2, which is the current gold standard. When the two methods had inconsistent results, next-generation sequencing–based CancerSCAN was utilized as a referee.
Results:
The overall agreement of the two methods was 97.4% (93.9%-99.1%); the positive percent agreement, 95.0% (88.7%-98.4%); and the negative percent agreement, 100.0% (95.9%-100.0%). EGFR mutations were detected at a frequency of 50.3% using the ADPS EGFR Mutation Test Kit and 52.9% using the cobas EGFR Mutation Test v2. There were 10 discrepant mutation calls between the two methods. CancerSCAN reproduced eight ADPS results. In two cases, mutant allele fraction was ultra-low at 0.02% and 0.06%, which are significantly below the limit of detection of the cobas assay and CancerSCAN. Based on the EGFR genotyping by ADPS, the treatment options could be switched in five patients.
Conclusion
The highly sensitive and specific ADPS EGFR Mutation Test Kit would be useful in detecting the patients who have lung cancer with EGFR mutation, and can benefit from the EGFR targeted therapy.

This paper provides a comprehensive overview of the Cancer Public Library Database (CPLD), established under the Korean Clinical Data Utilization for Research Excellence project (K-CURE). The CPLD links data from four major population-based public sources: the Korea National Cancer Incidence Database in the Korea Central Cancer Registry, cause-of-death data in Statistics Korea, the National Health Information Database in the National Health Insurance Service, and the National Health Insurance Research Database in the Health Insurance Review & Assessment Service. These databases are linked using an encrypted resident registration number. The CPLD, established in 2022 and updated annually, comprises 1,983,499 men and women newly diagnosed with cancer between 2012 and 2019. It contains data on cancer registration and death, demographics, medical claims, general health checkups, and national cancer screening. The most common cancers among men in the CPLD were stomach (16.1%), lung (14.0%), colorectal (13.3%), prostate (9.6%), and liver (9.3%) cancers. The most common cancers among women were thyroid (20.4%), breast (16.6%), colorectal (9.0%), stomach (7.8%), and lung (6.2%) cancers. Among them, 571,285 died between 2012 and 2020 owing to cancer (89.2%) or other causes (10.8%). Upon approval, the CPLD is accessible to researchers through the K-CURE portal. The CPLD is a unique resource for diverse cancer research to investigate medical use before a cancer diagnosis, during initial diagnosis and treatment, and long-term follow-up. This offers expanded insight into healthcare delivery across the cancer continuum, from screening to end-of-life care.

Objective:
This study aimed to analyze the trends in cervical cancer screening rates, including organized and opportunistic cancer screening rates, with the Papanicolaou test among Korean women.
Methods:
Data were collected from a nationwide, cross-sectional, Korean National Cancer Screening Survey. To evaluate the cervical cancer screening rates, we used the screening approach of “cervical cancer screening rate with recommendation,” defined as the proportion of women who underwent the Papanicolaou test during the previous 2 years according to the Protocol of National Cancer Screening Program for Cervical Cancer in Korea. The joinpoint regression analysis, which describes the annual percent change (APC), was performed to detect significant changes in cervical cancer screening rates in women aged 30-74 years during 2005-2020.
Results:
The cervical cancer screening rate was 56.0% in 2020. From 2005 to 2013, there was a rising trend in cervical cancer screening rates (APC=2.70%, 95% confidence interval [CI]:1.05 to 4.38), followed by a falling trend (APC=−2.67%, 95% CI:−4.3 to −1.01). The falling trend was significantly associated with age (≥40 years), education level (below the 15th grade), household income (below the middle-income level), and residence (all residential areas).
Conclusion
The recent falling trend was more common in women with a low socioeconomic status, which suggests that there is a socioeconomic gap in cervical cancer screening. Moreover, young women in their thirties had a low screening rate. Therefore, an active participation strategy for women vulnerable to cervical cancer is required.

Background/Aims:
Screening for colorectal cancer (CRC) is important in reducing the morbidity and mortality of CRC. Thus, this study aimed to describe the trends of CRC screening in both organized and opportunistic settings in Korea from 2005 to 2020 according to sociodemographic characteristics.
Methods:
This study analyzed the data of adults aged 50 to 74 years from the Korean National Cancer Screening Survey. Trends for CRC screening rates (fecal immunochemical test [FIT] within the last year, double-contrast barium enema within the last 5 years, or colonoscopy within the last 10 years for 2005–2018 and FIT within the last year or colonoscopy within the last 10 years for 2019–2020) were analyzed using Joinpoint regression. The trends were also analyzed according to sociodemographic characteristics, including age, sex, monthly household income, education level, and residential area.
Results:
A total of 29,040 participants were included in the analysis. The CRC screening rate significantly increased from 25.0% to 60.1%, with an annual percent change (APC) of 9.2% between 2005 and 2014, followed by a nonsignificant increase to 64.4% between 2014 and 2020 (APC,1.7%). When the participants were stratified according to sociodemographic factors, the participants with higher household income and education levels generally had higher screening rates.
Conclusions
There has been substantial improvement in CRC screening rates in the general Korean population. However, it is necessary to determine why the screening rate has stabilized since 2014 and identify barriers that cause disparities in CRC screening rates among populations with lower socioeconomic status.

Journal of Korean Medical Science 2022;37(24):e196-
Background:
Acinetobacter baumannii infections cause high morbidity and mortality in intensive care unit (ICU) patients. However, there are limited data on the changes of longterm epidemiology of imipenem resistance in A. baumannii bacteremia among pediatric ICU (PICU) patients.
Methods:
A retrospective review was performed on patients with A. baumannii bacteremia in PICU of a tertiary teaching hospital from 2000 to 2016. Antimicrobial susceptibility tests, multilocus sequence typing (MLST), and polymerase chain reaction for antimicrobial resistance genes were performed for available isolates.
Results:
A. baumannii bacteremia occurred in 27 patients; imipenem-sensitive A. baumannii (ISAB, n = 10, 37%) and imipenem-resistant A. baumannii (IRAB, n = 17, 63%). There was a clear shift in the antibiogram of A. baumannii during the study period. From 2000 to 2003, all isolates were ISAB (n = 6). From 2005 to 2008, both IRAB (n = 5) and ISAB (n = 4) were isolated. However, from 2009, all isolates were IRAB (n = 12). Ten isolates were available for additional test and confirmed as IRAB. MLST analysis showed that among 10 isolates, sequence type 138 was predominant (n = 7). All 10 isolates were positive for OXA-23-like and OXA-51-like carbapenemase. Of 27 bacteremia patients, 11 were male (41%), the median age at bacteremia onset was 5.2 years (range, 0–18.6 years). In 33% (9/27) of patients, A. baumannii was isolated from tracheal aspirate prior to development of bacteremia (median, 8 days; range, 5–124 days). The overall case-fatality rate was 63% (17/27) within 28 days. There was no statistical difference in the case fatality rate between ISAB and IRAB groups (50% vs. 71%; P = 0.422).
Conclusion
IRAB bacteremia causes serious threat in patients in PICU. Proactive infection control measures and antimicrobial stewardship are crucial for managing IRAB infection in PICU.

Objective:
If empirical antibiotics must be administered, the pharmacy needs to deliver the drug to emergency patients as soon as possible. The purpose of this study was to investigate the impact of the installation of an automated dispensing cabinet system in an emergency center.
Methods:
A retrospective study was conducted through the analysis of medical records in an emergency medical center for 12 months before and after the installation of the system. The order-to-antibiotic time and door-to-antibiotic time were collected retrospectively through a system log analysis. For the satisfaction survey, nursing providers who use the dispensing system were administered a survey questionnaire related to the system.
Results:
This study covered 1,292 prescriptions before and 1,377 after the introduction of the system in the emergency center. It was observed that the average time from the order-to-drug administration decreased (48.7±57.9 vs. 41.1±52.3, P=0.001) after the introduction of the system. The door-to-drug administration time also showed a decrease (293.6±260.2 vs. 267.4±221.1, P=0.006). A satisfaction survey was conducted on 38 users of the system who agreed to participate and respond. The score of the satisfaction survey was 3.63±0.44. The user response showed that they were most satisfied with the prevention of medication errors (4.00±0.62) and system control (4.00±0.57).
Conclusion
The automated dispensing cabinet system in an emergency center can shorten the order-to-drug time and door-to-drug time. In addition, it helps to improve the satisfaction and work efficiency of emergency medical workers related to medication dispensation.
