Background: Coronavirus disease 2019 (COVID-19) vaccination is necessary to reach herd immunity and essential for mitigating the spread of the pandemic. In May 2021, the US FDA and the EU have expanded the emergency use authorization for a COVID-19 vaccine to children aged 12 to 15. The aim of this study was to investigate parental acceptability of COVID-19 vaccination for their children, factors affecting their acceptability, and children's perceptions of COVID-19 vaccines in Republic of Korea. Methods: We conducted a questionnaire survey at two tertiary hospitals from May 25, 2021 to June 3, 2021. Subjects were parents having children under 18 years and children aged 10–18 years. Results: Two hundred twenty-six parents and 117 children aged 10–18 years were included in the final analysis. Overall, 76.5% and 64.2% of parents intended to get vaccinated against COVID-19 and intended to have their children vaccinated, respectively. However, only 49.6% of children responded that they would get COVID-19 vaccination. In the multivariate analysis, high confidence in the safety of COVID-19 vaccines (adjusted odds ratio [AOR], 4.87; 95% confidence interval [CI], 1.32–24.12), parents' willingness to vaccinate themselves (AOR, 19.42; 95% CI, 6.85–64.00), and awareness of the need to vaccinate children against COVID-19 (AOR, 13.15; 95% CI, 4.77–41.27) were associated with positive factors intention to vaccinate their children. Conclusion This study provides insight into how parents think about the COVID-19 vaccine for their children in South Korea. Our findings could be referenced in establishing a policy for childhood COVID-19 vaccination in the future.

Coronavirus disease 2019 (COVID-19) is generally milder in children than in adults, and a substantial proportion of children with the disease have asymptomatic infections.Remdesivir is recommended for severe COVID-19. To date, there are little data on the outcomes of remdesivir treatment in children. We report a case of severe COVID-19 in a previously healthy but obese (body mass index, 27.6; 99.8 th percentile of the age) 9-year-old boy treated with remdesivir and dexamethasone. The patient had pneumonia at the time of diagnosis and required supplemental oxygen due to hypoxia one day after diagnosis. The patient developed respiratory distress as his pneumonia progressed rapidly. Therefore, remdesivir with dexamethasone therapy was initiated on hospital day 2. Supplemental oxygen was gradually weaned on hospital day 6 and stopped on hospital day 9. Significant improvement in pneumonic consolidations on chest X-ray was noted on hospital day 8. The patient was discharged on hospital day 21. We did not observe any adverse effects of remdesivir therapy and successfully treated a 9-year-old child with severe COVID-19.

BACKGROUND: Pancreatic pseudocysts are localized collections of pancreatic secretions in a cystic structure that lack an epithelial lining and occur as a result of surrounding tissues walling off and containing a pancreatic duct disruption. METHODS: This is paper presents a clinical analysis of 32 cases of pancreatic pseudocysts treated from January 1987 to July 1997 at Pusan Medical Center. RESULTS: The results are summarized briefly as follows: 1) The age and the sex distributions of these patients showed that 19 cases occurred between the 3rd and the 4th decades and the male-to-female ratio was 10.3:1. 2) Pancreatitis was most frequently associated with pancreatic pseudocysts (75%). 3) Common clinical manifestations were abdominal pain (89%), abdominal tenderness (78%), nausea and vomiting (56%), abdominal mass (32%), abdominal distension (31%). 4) Abdominal CT and ultrasound were major diagnostic methods. 5) The location of the peudocysts were the body (41%), head and tail (31%), the tail (22%), and others (6%). 6) The sizes of the pseudocysts were as follows less than 5 cm (5 cases), 5-10 cm (19 cases), above 11 cm (8 cases) in 32 cases. 7) Valuable laboratory data for a pancreatic pseudocyst were blood WBC count (above 10,000/mm in 78%), serum amylase (above 160 unit/L in 62%), urine amylase (above 300 unit/L in 56%), blood glucose (above 110 mg/L in 50%), serum alkaline phosphatase (above 250/L in 44%). 8) The surgical methods in 29 cases were excision (1 case), external drainage (4 cases), cystogastrostomy (7 cases), cystojejunostomy (16 cases), cystoduodenostomy (1 case). 9) Postoperative complications were encountered in 13 cases, and many of the cases involved pulmonary complications and wound infections. CONCLUSIONS: Currently, treatment of patients with pancreatic pseudocysts is based on the clinical setting, the presence or absence of symptoms, the age and size of the pseudocyst, and the presence or absence of complications. In the most common clinical settings, a pseudocyst is discovered after an episode of acute alcoholic pancreatitis.

An evaluation of axillary block in 803 clinical cases, during the period from January 1974 to June 1979, was made. Satisfactory results were obtained in 756 out of 803 blocks (94. 2%) with the axillary perivascular technique. The authors feetl that the axillary perivascular technique in which a relatively large volume(40~50ml) of anesthetic solution was administered into the perivasculsr space of the axilla was simple, convenient and had no serious complications compared to the supra-or subclavian perivascular technique and interscalene block for a diagnosis and treatment of upper extremities.

OBJECTIVE: The purpose of this study was to compare the skeletal, dental, and soft-tissue treatment effects of nonextraction therapy using the modified C-palatal plate (MCPP) to those of premolar extraction (PE) treatment in adult patients with Class II malocclusion. METHODS: Pretreatment and posttreatment lateral cephalographs of 40 adult patients with Class II malocclusion were retrospectively analyzed. The MCPP group comprised 20 patients treated with total arch distalization of the maxillary arch while the PE group comprised 20 patients treated with four PE. Fifty-eight linear and angular measurements were analyzed to assess the changes before and after treatment. Descriptive statistics, paired t-test, and multivariate analysis of variance were performed to evaluate the treatment effects within and between the two groups. RESULTS: The MCPP group presented 3.4 mm of retraction, 1.0 mm of extrusion, and 7.3° lingual inclination of the maxillary central incisor. In comparison, the PE group displayed greater amount of maxillary central incisor retraction and retroclination, mandibular incisor retraction, and upper lip retraction (5.3 mm, 14.8°, 5.1 mm, and 2.0 mm, respectively; p < 0.001 for all). In addition, the MCPP group showed 4.0 mm of distalization and 1.3 mm of intrusion with 2.9° distal tipping of the maxillary first molars. CONCLUSIONS: These findings suggest the MCPP is an effective distalization appliance in the maxillary arch. The amount of incisor retraction, however, was significantly higher in the PE group. Therefore, four PE may be recommended when greater improvement of incisor position and soft-tissue profile is required.

OBJECTIVE: Taxol (paclitaxel)-induced apoptosis was studied to understand their biological mechanism correlated with the expression of p53 in the SKOV-3 and OVCAR-3 ovarian cancer cell lines. MATERIALS AND METHODS: The SKOV-3 and OVCAR-3 cell lines were cultured in RPMI 1640 medium without taxol (control group) and with taxol for 24 h and 48 h (experimental group). After harvest, the cells were stained with annexin V-FITC (fluorescein isothiocyanate) and anti-cytokeratin antibodies (clone CAM5.2 and clone MNF116). They were washed and stained with p53 antibody. After then the secondary antibodies, i.e., FITC- or phycoerythrin (PE)-conjugated goat anti-mouse (GAM) immunoglobulin G (GAM IgG-FITC or GAM IgG-PE) were added in the cells and they were incubated in the dark. DNA of these cells were stained sequentially with propidium iodide (PI). Standard FACScan equipped with a 488 nm single laser was used for the analysis of these cells. RESULTS: Both of SKOV-3 and OVCAR-3 cell lines were arrested in the G2M phase after treatment of taxol, suggesting that these cells would eventually enter into the stage of cell death. Fractions of negative cytokeratin and positive annexin V and amount of sub-G0G1 fraction indicative of apototic fractions were lower in the SKOV-3 cell line compared with that in OVCAR-3 cell line, probably as a result of lower sensitivity of SKOV-3 cell line to the taxol. p53 expression were not detected in SKOV-3 cell line. On the basis of observed findings in SKOV-3 cell line and findings of high expressions of p53 regardless of taxol treatment, no increases in their expressions according to culturing time, and gradual increases in sub-G0G1 fractions and in fractions of negative cytokeratin and positive annexin V indicative of apoptosis in OVCAR-3 cell line, we concluded that the expression of p53 would not be associated with cell cycle changes and the arrest in the G2M pahse but associated with the appearance of apotosis. CONCLUSION: Our results suggest that flow cytometric detection of the apoptotic fractions would be an effective, fast, and accurate method for the chemosensitivity test in tumor cells before the administration of anti-cancer drugs in gynecologic cancer patients.

Kasabach-Merritt phenomenon does not occur with common hemangioma, rather it is associated with the more aggressive Kaposiform hemangioendothelioma and rarely with other vascular neoplasm. We report the case of an adult who was diagnosed as Kaposiform hemangioendothelioma complicated by Kasabach-Memtt phenomenon. This is the first report in Korea of an adult with Kasabach-Merritt phenomenon who has osteolytic changes of femur, pelvic bone, and lumbar spine.
