Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean version of the Apathy Evaluation Scale Short Form (K AES-10) for people with dementia. Methods: Participants in this study were 198 patients with dementia resident in two hospitals in the Republic of Korea. The AES-10 was translated into Korean through the translation and adaptation of instruments process developed by the World Health Organization. This process was carried out by three bilingual nursing professionals. Validity and reliability, such as construct validity, convergent validity, Cronbach's ⍺, inter-rater reliability, and test-retest reliability, were evaluated. IBM SPSS Statistics 25.0 and AMOS 26.0 programs were used for the data analysis. Results: A uni-dimensional model was proposed in the explanatory factor analysis; a single factor accounted for 68.0% of total variances. The confirmatory factor analysis supported the validity of the Korean version of the AES-10. The scale had a Cronbach's ⍺ of .95, inter-rater reliability of .66 (p<.001), and a test-retest reliability of .81 (p<.001). Conclusion The findings show that the Korean version of the AES-10 is both valid and reliable for measuring apathy among people diagnosed with dementia in the Republic of Korea.

PURPOSE: Hematopoietic cell transplantation (HCT) recipients are vulnerable to invasive infection by Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae (Sp). This study was performed to evaluate immune responses after Hib and Sp vaccination in Korean pediatric HCT recipients. METHODS: Patients were prospectively enrolled at Samsung Medical Center during 2009-2011. ELISA tests to detect anti-PRP IgG antibody and antibodies to Sp serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F were performed at the Center for Vaccine Evaluation and Study, Ewha Medical Research Institute. RESULTS: Ten patients (two allogeneic, eight autologous recipients) with median age 5.4 years (range 2.7-12.2 years) were enrolled. Before Hib vaccination, 60% of patients' anti-PRP IgG titers were below 0.15 microg/mL. After vaccination, 100% of patients' anti-PRP IgG titers increased above 0.15 microg/mL (cut-off value for detection) and 1.0 microg/mL (cut-off value for seroprotection). For pneumococcus, in 2-5 year-old patients, pre-vaccination geometric mean concentrations (GMCs) of IgG for six serotypes (4, 6B, 9V, 14, 18C, and 23F) were below 0.35 microg/mL and at 5 months post-vaccination GMCs of IgG for all seven serotypes increased to above 0.35 microg/mL. In patients older than 5 years, pre-vaccination GMCs of IgG for four serotypes (4, 9V, 14, and 23F) were below 0.35 microg/mL and at 3 months post-vaccination GMCs of IgG for all seven serotypes increased to above 0.35 microg/mL. CONCLUSION: Most HCT recipients had low or no protective antibodies to Hib and Sp before vaccination, but showed good immune responses to protective levels after vaccination.

BACKGROUND: Hemoglobin A1c (HbA1c) is considered a marker useful for the follow-up and diagnosis of diabetes and implies the importance of reliable assay methods that are traceable to a reference method. We evaluated analytical performance of a new high-performance liquid chromatography system for the HbA1c assay: D-100 from Bio-Rad Laboratories (USA). METHODS: We evaluated precision, linearity, and carry-over of D-100, according to the Clinical and Laboratory Standards Institute's guidelines. Comparative analysis of D-100 with Integra 800 (Roche Diagnostics, Germany) and Capillarys 3 (Sebia, France) was conducted. Additionally, we evaluated the throughput of the three instruments. RESULTS: Precision of low- and high-concentration controls in D-100 showed a CV of less than 1%. The linearity was excellent (R²=0.999) in the range of 3.51-18.7%, and carry-over was not observed. HbA1c results of D-100 (n=144) showed good correlation with those of Integra 800 (r=0.993) and Capillarys 3 (r=0.996). The % bias between D-100 and Integra 800 or Capillarys 3 was within the allowable range at all 3 medical decision levels (5.7%, 6.5%, and 10.0%). Elapsed time in the analysis of the first sample by D-100 was shorter than that of Integra 800 (2.4 vs. 11.1 minutes), but subsequent samples took more time (0.8 vs. 0.3 minutes per sample). CONCLUSIONS: D-100 showed reliable analytical performance with good precision and linearity, minimal carry-over, and acceptable comparative characteristics relative to other instruments. D-100 is expected to be useful for clinical measurements of HbA1c for diabetes diagnosis and theranostics.

BACKGROUND: Emergencies in dentistry can be classified as medical and dental. Medical emergencies occur mainly during dental treatment in patients with a systemic disease. Dental emergency departments are largely divided into dental emergency rooms located in dental college hospitals and medical emergency rooms located in medical institutions. This study aimed to analyze the characteristics of and provide help to dental emergency patients in a dental hospital. METHODS: Overall, 1806 patients admitted to a dental emergency room at Yonsei University Dental Hospital for 1 year were included. The data collection period was from October 1, 2014 to September 30, 2015. An investigator reviewed medical records from the electronic medical record (EMR) system and radiographs. RESULTS: The patients were 1,070 men and 736 women. The sex ratio was 1.45:1. The commonest age group was of 0–9 years, including 451 (25.0%) patients, followed by 20–29 years, including 353 (19.5%) patients, and 30–39 years, including 277 (15.3%) patients. Of the 108 patients transferred to the Severance emergency department, 81 had trauma, 19 were in pain, 4 were bleeding, and 4 had other complaints. Among chief complaints, 1,079 patients (60.3%) had trauma, 564 (31.5%) had pain, and 75 (4.2%) had bleeding. Twenty-three cases (1.3%) were caused by temporomandibular disorder (TMD). CONCLUSION: Dentists should be able to adequately assess patients in a dental emergency room and treat trauma, pain, and bleeding.

Pancreatic acinar cell carcinoma (ACC) is a rare neoplasm accounting less than 1% of malignant pancreatic tumors. A 47-year-old male patient visited the emergency room with epigastric pain. Computed tomography or magnetic resonance imaging revealed a 4.7-cm heterogeneously enhanced solid and cystic mass with internal necrosis located in the head of the pancreas. Radiological diagnosis was borderline malignancy such as neuroendocrine tumor or solid pseudopapillary neoplasm. Two months later, the necrotic mass in the pancreas head had grown up to 11 cm, compressing the duodenum, superior mesenteric vein, and proximal transverse colon. Pylorus preserving pancreatoduodenectomy with segmental resection of transverse colon was performed. Histopathological examination revealed that the tumor was pancreatic ACC. The patient recovered without any complication and was doing well without recurrence for 12 months after surgery.

Objective: The authors analyzed the characteristics of pediatric patients who visited trauma center due to injuries sustained while riding scooters and suggested recommendations on our concerns about pediatric scooter use. Methods: From January 2019 to June 2022, we collected data for those who visited due to accidents while riding scooters. And, the analysis was conducted by dividing it into pediatric (younger than 12 years) and adult (older than 20 years) patients. Results: There were 264 children (<12 years), and 217 adults (>19 years). We observed 170 head injuries (64.4%), in the pediatric population and 130 head injuries (60.0%) in the adult population. There were no significant differences between pediatric and adult patients for all three injured regions. Among pediatric patients, only 1 reported the use of protective headgear (0.4%). The patient suffered a cerebral concussion. However, 9 of the pediatric patients who did not wear protective headgear suffered major trauma. Among 217 adult patients, 8 (3.7%) had used headgear. 6 suffered major trauma and 2 suffered minor trauma.Of the patients who did not wear protective headgear, 41 suffered major trauma and 81 suffered minor trauma. Since there was only one patient in the pediatric group who wore headgear, no statistical inferences could be calculated. Conclusion In the pediatric population, the head injury rate is as high as in adults. We were unable to statistically support the significance of headgear in the current study. However, in our general experience, the importance of headgear is overlooked in the pediatric population compared to adults. It is necessary to encourage the use of headgear actively publicly.

Objectives: People-centered care and social protection are critical for improving tuberculosis (TB) treatment outcomes. This study aimed to evaluate whether a vulnerability assessment tool, developed for an enhanced community-based care and management (ECCM) program in 2 Korean cities, could predict and improve final TB treatment outcomes based on patients’ vulnerability levels. Methods: Treatment outcomes in the ECCM group were compared with those in a control group, stratified by vulnerability level. During stage 1, one city served as the intervention region and the other as the control, with a crossover in stage 2. The vulnerability assessment included all notified patients with TB, and those identified as highly vulnerable in the intervention group received social support following a consultation with a case manager. Results: The vulnerability assessment tool demonstrated moderate predictive ability for unfavorable outcomes, with an area under the curve of 0.70 (95% confidence interval, 0.63 to 0.77). The patients with high vulnerability who received ECCM treatment demonstrated a 19.8-percentage point (%p) higher treatment success rate than the high vulnerability subcategory of the control group. ECCM also appeared to reduce loss to follow-up and TB-related mortality by 8.4%p and 7.3%p, respectively, although these findings should be interpreted with caution. Conclusions The results suggest that providing social support tailored to patient vulnerability at the time of diagnosis could improve TB treatment outcomes.

BACKGROUND: Postoperative nausea and vomiting (PONV) frequently occurs following bimaxillary orthognathic surgeries. Compared to opioids, Nefopam is associated with lower incidences of PONV, and does not induce gastrointestinal tract injury, coagulopathy, nephrotoxicity, or fracture healing dysfunction, which are common side effects of Nonsteroidal anti-inflammatory drugs. We compared nefopam- and fentanyl-induced incidence of PONV in patients with access to patient-controlled analgesia (PCA) following bimaxillary orthognathic surgeries. METHODS: Patients undergoing bimaxillary orthognathic surgeries were randomly divided into nefopam and fentanyl groups. Nefopam 120 mg or fentanyl 700 µg was mixed with normal saline to a final volume of 120 mL. Patients were given access to nefopam or fentanyl via PCA. Postoperative pain intensity and PONV were measured at 30 minutes and 1 hour after surgery in the recovery room and at 8, 24, 48, and 72 hours after surgery in the ward. The frequency of bolus delivery was compared at each time point. RESULTS: Eighty-nine patients were enrolled in this study, with 48 in the nefopam (N) group and 41 in the fentanyl (F) group. PONV occurred in 13 patients (27.7%) in the N group and 7 patients (17.1%) in the F group at 8 hours post-surgery (P = 0.568), and there were no significant differences between the two groups at any of the time points. VAS scores were 4.4 ± 2.0 and 3.7 ± 1.9 in the N and F groups, respectively, at 8 hours after surgery (P = 0.122), and cumulative bolus delivery was 10.7 ± 13.7 and 8.6 ± 8.5, respectively (P = 0.408). There were no significant differences in pain or bolus delivery at any of the remaining time points. CONCLUSION: Patients who underwent bimaxillary orthognathic surgery and were given nefopam via PCA did not experience a lower rate of PONV compared to those that received fentanyl via PCA. Furthermore, nefopam and fentanyl did not provide significantly different postoperative pain control.
