The authors have analysed 39 rheumatoid wrists in 25 rheumatoid patients, who underwent vsrious surgeries including arthroscopic and open synovectomy, partial and total arthrodesis and total wrist arthroplasty at the department of orthopaedic surgery, St. Mary's Hospital from November 1985 to April 1988, and the effect of eaeh surgery on the wrist function and proper time of operation are discussed. The results were as follows; 1. The patients who were classified as a classical rheumatoid arthritis according to the ARA criteria were four males and twenty-one females, with a mean age of 43 yesrs, and the functional capacity of the patients before operation was graded in III for twenty-threeand in IV for two patients. 2. Out of 25 patients (39 wrists), 14 patients are in bilateral and II patients in unilateral involvement. The synovectomy in 13 wrists, arthrodesis in 24 wrists and total joint replacement in 2 wrists were performed and followed them for average 17 months after operation. 3. The synovectomy were done for 13 wrists in grade II and III according to the classification of rheumstoid arthritis by radiology(3). There were two cases of recurrence in the cases of synovectomy, but not in replacement and arthrodesis. 4. The arthrodesis of wrist was performed for 24 wrists-bilateral arthrodesis in 3 patient (6 wrists) and unilateral fusion in 18 patients. For 4 cases out of 24 cases of wrist arthrodesis, the second and third carpo-metacsrpal joints were fused simultaneously. 5. Protek total wrist arthroplasty was done in 2 cases snd followed them for more than9 months with relatively good clinical results. Finally, it is our beliefs for rheumatoid wrists that surgery is often indicated to control the various wrist problems, early synovectomy is strongly indicated, and partial wrist fusion has proven to be effective in patients with moderate destruction, deformity and pain, but the total wrist arthrodesis and arthroplasty is still in controversy. The proper surgery for rheumatoid wrist should be determined by the clinical severity of disease and radiological changes of wrist.

OBJECTIVES:
This study investigated the reporting rates of adverse events following immunization (AEFIs) to the spontaneous reporting system (SRS) and its predictors among individuals with AEFIs after coronavirus disease 2019 (COVID-19) vaccination.
METHODS:
A cross-sectional, web-based survey was conducted from December 2, 2021 to December 20, 2021, recruiting participants >14 days after completion of a primary COVID-19 vaccination series. Reporting rates were calculated by dividing the number of participants who reported AEFIs to the SRS by the total number of participants who experienced AEFIs. We estimated adjusted odds ratios (aORs) using multivariate logistic regression to determine factors associated with spontaneous AEFIs reporting.
RESULTS:
Among 2,993 participants, 90.9% and 88.7% experienced AEFIs after the first and second vaccine doses, respectively (reporting rates, 11.6 and 12.7%). Furthermore, 3.3% and 4.2% suffered moderate to severe AEFIs, respectively (reporting rates, 50.5 and 50.0%). Spontaneous reporting was more prevalent in female (aOR, 1.54; 95% confidence interval [CI], 1.31 to 1.81); those with moderate to severe AEFIs (aOR, 5.47; 95% CI, 4.45 to 6.73), comorbidities (aOR, 1.31; 95% CI, 1.09 to 1.57), a history of severe allergic reactions (aOR, 2.02; 95% CI, 1.47 to 2.77); and those who had received mRNA-1273 (aOR, 1.25; 95% CI, 1.05 to 1.49) or ChAdOx1 (aOR, 1.62; 95% CI, 1.15 to 2.30) vaccines versus BNT162b2. Reporting was less likely in older individuals (aOR, 0.98; 95% CI, 0.98 to 0.99 per 1-year age increment).
CONCLUSIONS
Spontaneous reporting of AEFIs after COVID-19 vaccination was associated with younger age, female sex, moderate to severe AEFIs, comorbidities, history of allergic reactions, and vaccine type. AEFIs under-reporting should be considered when delivering information to the community and in public health decision-making.

Background:
Rare cases of Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C) have been reported following the coronavirus disease 2019 (COVID-19) vaccination; however, the association between COVID-19 vaccination and the risk of developing KD/MIS-C has not yet been established.
Methods:
We conducted a self-controlled case series analysis using a large-linked database that connects the COVID-19 immunization registry with nationwide claims data. We identified individuals aged < 18 years who received their initial COVID-19 vaccination and had a KD/MIS-C diagnosis with a prescription for intravenous immunoglobulin or corticosteroids between October 18, 2021, and April 15, 2023. The observation period was set as 240 days from the date of the COVID-19 vaccination. The risk window was 60 days after vaccination, with the remaining observation period serving as the control window. The incidence rate ratios (IRRs) and 95% confidence intervals (CIs) in the risk versus control windows were estimated using the conditional Poisson regression model. We further analyzed the vaccine doses and types for secondary analysis. We also performed subgroup analyses stratified by sex, age, comorbidities, and other conditions and sensitivity analyses by varying the length of the risk window and outcome definition.
Results:
Among 2,369,490 individuals who received the COVID-19 vaccination, 12 cases of KD/MIS-C were identified, which included five and seven patients in the risk and control windows, respectively. There was no increased risk of KD/MIS-C within the 60-day period of vaccination (IRR, 0.53; 95% CI, 0.17–1.60). Secondary subgroup and sensitivity analyses showed no significant increase in the risk of KD/MIS-C after COVID-19 vaccination, which is consistent with the results of the main analysis.
Conclusion
The results of this nationwide study suggest that the risk of developing KD/MIS-C did not increase after COVID-19 vaccination. However, owing to the lack of a sufficient number of cases, future studies utilizing multinational long-term follow-up databases should be conducted. Considering the increasing incidence of KD/MIS-C and the limited understanding of its precise biological mechanisms, additional research on KD/MIS-C is warranted.

OBJECTIVE: The purpose of this study was to examine the long-term effects of Hospital Information System(HIS) on nurses' job pattern and satisfaction, and attitudes toward electronic medical record system. METHODS: Prospective survey using repeated measures design was performed to compare the changes between 2 years and 4 years after introduction of HIS in a tertiary hospital. Participants were 374 nurses working in the target hospital. Questionnaire was developed by researchers based on Walker, Eyman, Krall, Prophet, and Flanagan(1996)'s study and consisted of 21 questions about job pattern, job satisfaction, and attitudes toward computerization and paper record system. RESULTS: Overall time for documentation, shift reporting, communication with other departments were reduced. Otherwise, direct nursing time was not increased after HIS. Nurses showed positive responses on changes of job pattern after HIS while job satisfaction has been decreased. In addition, nurses' attitudes toward hospital information system and paper medical record system showed they were accepting computerized information system. CONCLUSION: This study identified the long-term positive effects of HIS and the need for nursing sensitive hospital information system.

Journal of Korean Neurosurgical Society 2004;36(6):448-453
OBJECTIVE: To study the safety and efficacy of using rectangular titanium cage(RABEA) for anterior cervical fusion, we have compared the results of fusion performed by using fibula allograft and RABEA cage. METHODS: Total of 74 patients with single level cervical discectomy were included in this study. Allogenic fibula bone graft alone was done in 38 patients and RABEA cage was inserted in 36 patients. Retrospective clinical analysis was based on review the symptoms and radiological findings on both two groups at postoperative 12 months. RESULTS: Solid fusion was achieved in 95% of patients who received rectangular titanium cage and 74% of patients who received fibula allograft. According to Odom's criteria, 92% of patients were found to have excellent or good results in the RABEA cage group and 68% of patients in allograft group. Functional outcome was assessed according to Odom's criteria and patient's postoperative satisfaction index(PSI). Better clinical outcome and solid fusion could be achieved by rectangular titanium cage fusion than allogenic fibula graft after single level anterior cervical discectomy. CONCLUSION: We believe that RABEA cage is an effective and safe cervical fusion substitute for single level cervical fusion after discectomy.
