Objectives: This study addressed longstanding issues in Korea’s public health dentist system by defining and standardizing job duties. A practical job description was drafted based on job analysis results to promote work efficiency and lay the groundwork for future educational programs. Methods: The job description elements were selected and drafted based on previous studies.These drafts were revised and refined with expert panel validation. Results: The main job duties of public health dentists encompass community oral health, dental practice, public oral health research, and special oral health, tailored for institutions such as health sub-centers, health centers, health clinics, national health organizations, and correctional facilities. For community oral health at public health subcenters involves 12 key duties including projects, education, and community engagement. Public health centers/clinics focus on 16 key duties mainly around health project planning and evaluation. Dental care across both settings has 15 main duties. Public oral health research emphasizes community surveys and epidemiology. Special oral health in correctional facilities covers 11 main duties including education and external resource linking. Conclusions It concluded that for the development of public health dentists in South Korea, it is necessary to develop public health dentist education programs to promote the performance of public health dentists and to equip them with the competencies necessary to perform such duties, focusing on job descriptions organized around the characteristics of workplaces and major tasks.

Objectives: This study is an effectiveness evaluation study of an oral health education program conducted on 30 visiting nurses who participated in the “CHAT-DONG” project in a district of Seoul, Korea. The primary objective of this study is to obtain basic data for the development of an oral healthcare education program for visiting nurses. Methods: To evaluate the effectiveness of the educational program comprising lecture and small group practice training, oral health knowledge, beliefs, awareness, self-efficacy, and oral health status assessment capabilities were assessed before and after the training, using Google online surveys. Finally, data from 22 participants were used for analysis. Results: Overall oral health knowledge improved after the training, however, specific oral disease knowledge was low. There were no significant changes in oral health beliefs and awareness, but there was a significant increase in self-efficacy. The ability to assess oral health status improved a little, however, the ability to express specific oral health conditions was low. This may be owing to the limitations of a one-time training and the inexperience and unfamiliarity of the participants. The participating nurses were highly satisfied with the training program and expressed a strong desire for regular and ongoing training. Conclusions This study highlights the necessity for systematic and sustained training programs for healthcare personnel, including visiting nurses, to provide effective oral healthcare to older adults.Furthermore, the development of such training programs should consider the demographic characteristics of the target population and their level of prior knowledge and experience when designing, implementing, and evaluating training programs.

This study aimed to analyze the extent of oral health problems among elderly residents of longterm care facilities who have difficulties accessing care at dental clinics due to physical limitations and other challenges. Seventy-four elderly individuals residing in long-term care facilities in A-gu, Seoul, were screened. From these, we randomly selected three older adults (MMSE-K≥24) who were able to communicate freely in the study. Relevant information was obtained through document review, observational surveys, and one-on-one interviews to identify oral health problems and physical limitations experienced by these older adults. The elderly in long-term care facilities experienced pain and discomfort due to oral problems, and improperly fitting dentures and other prosthetics. These oral problems led to limitations in compromised oral functions and alterations in dietary patterns. Despite the need for customized oral care and treatment, the specific oral health needs of the elderly residents were not met due to barriers that hindered their access to healthcare facilities, such as restricted mobility. To alleviate oral functional limitations in elderly residents of long-term care facilities, interventions, such as necessary treatments and personalized oral care, should be implemented. Establishing a systematic approach, including timely visits to long-term care facilities by dentists and a referral system between facilities and dental services, is crucial to optimizing dental care for elderly individuals living in residential aged care.

Purpose: Mycoplasma pneumoniae pneumonia (MP) is a major cause of community-acquired pneumonia (CAP) in children and is associated with extrapulmonary manifestations (EPM). The incidence and risk factors for EPM in children are unknown. Methods: This was a retrospective study involving 65,243 pediatric patients with CAP between 2010 and 2015 at 23 nationwide hospitals in South Korea. Medical records were reviewed to collect information regarding the clinical characteristics, radiological results, and laboratory findings. Logistic regression with multivariate analysis was performed to evaluate the risk factors associated with EPM in MP. Results: The incidence of EPM was 23.9%, including elevation of liver enzymes (18.1%), mucocutaneous manifestations (4.4%), proteinuria (4.1%), cardiovascular and neurological manifestations (0.4%), hematologic manifestations (0.2%), and arthritis (0.2%). Statistical analysis showed that mucocutaneous manifestations significantly increased with elevated alanine aminotransferase (adjusted odds ratio [aOR], 3.623; 95% confidence interval [CI], 1.933-6.790) and atopic sensitization (aOR, 2.973; 95% CI, 1.615–5.475) and decreased with respiratory virus coinfection (aOR, 0.273; 95% CI, 0.084–0.887). Elevated liver enzymes were significantly associated with elevated lactate dehydrogenase (aOR, 3.055; 95% CI, 2.257–4.137), presence of pleural effusion (aOR, 2.635; 95% CI, 1.767–3.930), and proteinuria with respiratory virus coinfection (aOR, 2.245; 95% CI, 1.113–4.527). Conclusion Approximately 24% of pediatric patients with MP had various EPM. As the risk factors associated with each EPM were different, it is necessary to evaluate the various clinical aspects and findings of MP to predict and prepare for the occurrence of EPM.

Purpose: Patients who have undergone gastrectomy have unique symptoms that are not appropriately assessed using currently available tools. This study developed and validated a symptom-focused quality of life (QoL) questionnaire for patients who have received gastrectomy for gastric cancer. Materials and Methods Based on a literature review, patient interviews, and expert consultation by the KOrean QUality of life in Stomach cancer patients Study group (KOQUSS), the initial item pool was developed. Two large-scale developmental studies were then sequentially conducted for exploratory factor analyses for content validity and item reduction. The final item pool was validated in a separate cohort of patients and assessed for internal consistency, test-retest reliability, construct validity, and clinical validity. Results The initial questionnaire consisted of 46-items in 12 domains. Data from 465 patients at 11 institutions, followed by 499 patients at 13 institutions, were used to conduct item reduction and exploratory factor analyses. The final questionnaire (KOQUSS-40) comprised 40 items within 11 domains. Validation of KOQUSS-40 was conducted on 413 patients from 12 hospitals. KOQUSS-40 was found to have good model fit. The mean summary score of the KOQUSS-40 was correlated with the EORTC QLQ-C30 and STO22 (correlation coefficients, 0.821 and 0.778, respectively). The KOQUSS-40 score was also correlated with clinical factors, and had acceptable internal consistency (> 0.7). Test-retest reliability was greater than 0.8. Conclusion The KOQUSS-40 can be used to assess QoL of gastric cancer patients after gastrectomy and allows for a robust comparison of surgical techniques in clinical trials.

Fetomaternal hemorrhage (FMH) is due to the entry of fetal blood into the maternal circulation. Although very rare, FMH complicates pregnancies, presents with severe symptoms, and leads to fetal death. Majority of FMH cases are idiopathic and difficult to diagnose. The known used diagnostic tests are Kleihauer-Betke Test (KBT) and flow cytometry, which can detect fetal hemoglobin in the maternal blood. However, such methods have limited use because of low sensitivity, labor-intensive and error-susceptible procedures, poor reproducibility, and tendency to overestimate the FMH volume. Other tests include high performance liquid chromatography (HPLC) and alpha-fetoprotein (AFP) tests, which can be as favorable to confirm FMH as KBT. However, in case of acute FMH, the diagnostic results of KBT, flow cytometry, and HPLC may be false negative. AFP test is a noninvasive, fast, easily assessable, adjuvant, and confirmatory diagnostic test. Published Korean articles show confirmed FMH by KBT or HPLC in singleton late-preterm and term neonates. Herein, we report a case of monochorionic diamniotic twin neonates (birth weight <1,500 g) who presented borderline fetal hemoglobin level because of acute FMH and were diagnosed with FMH by maternal AFP. Our experience of diagnosing FMH rapidly by AFP test will be very helpful to clinicians for the prevention and treatment of FMH during pregnancy.

Purpose: We aimed to analyze the correlations between the Bayley Scales of Infant Development (BSID)-III and Korean Developmental Screening Test (K-DST) in very-low-birth-weight (VLBW; birth weight <1,500 g) preterm infants. Methods: We enrolled 53 VLBW infants (mean gestational age, 28.9±2.11 weeks; mean birth weight, 1,158.5±241.1 g) and assessed them using the BSID-III and K-DST at a corrected age of 18 to 24 months. We analyzed the correlations between the BSID-III and K-DST subdomains and evaluated whether the estimated developmental levels were consistent with the corrected ages. Results: In the BSID-III, the composite scores for cognition, motor, and language were 105.9±13.1 (median, 105; 66th percentile; 95% confidence interval [CI], 98 to 113), 100.9±12.4 (100; 50th percentile; 95% CI, 92 to 108), and 94.9±16.8 (97.5; 34th percentile; 95% CI, 87 to 102), respectively. The scaled scores for receptive/expressive language and gross/fine motor were 9.9±2.9 (10.5)/8.2±2.7 (8) and 9.6±2.4 (9)/10.6 ±2.3 (10), respectively. In the K-DST, the mean scores of cognition (17.8±4.7 [18.5]), language (16.6±7.2 [20]), fine motor (19.4±3.4 [20]), gross motor (19.9±3.8 [21]), sociality (18.6±4.7 [20]), and self-control (17.3±5.1 [18]) were within the range of normal developmental status. Among the overlapping subdomains, cognition (r=0.58, P= 0.003) and language (r=0.86, P<0.001), but not fine and gross motor status (r=0.05, P= 0.79; r=0.16, P=0.44, respectively), showed significant correlation between the BSID-III and K-DST. Conclusion The language and cognition domains of the K-DST were significantly correlated with the BSID-III in preterm VLBW infants. Clinicians should consider these discrepancies and correlations when evaluating the developmental status of preterm VLBW infants.
