RESUMEN
The coronavirus disease-19 (COVID-19) pandemic leaded to inevitable expeditious vaccine rollout without sufficient safety profile. Especially, severe acute respiratory syndrome coronavirus 2 infection has known to induce overreacted immune responses such as releasing of proteinase-3 and myeloperoxidase (MPO) by neutrophil. This overreacted immune response leads to the concern of the development of autoimmune diseases after COVID-19 vaccination. We report the case of de novo MPO-associated systemic vasculitis involving central nervous system following heterogeneous mRNA1273 COVID-19 booster vaccination.
RESUMEN
Background@#The purpose of this study was to identify the distribution characteristics of radiological damage to the hand of rheumatoid arthritis patients and evaluate its effectiveness using a new damage assessment method. @*Methods@#Hand radiographs of a total of 127 rheumatoid arthritis patients were evaluated. We simplified the pre-existing van der Heijde modified total sharp score to assess the extent of bone damage. We selected 36 joints in both hands as regions of interest in our own way, and the erosion and joint space narrowing were scored. @*Results@#When the erosion and joint space narrowing score values of each joint of the hand were added together, the joint space narrowing score was higher than the overall erosion score. We can see that the scaphoid,lunate,radius and ulnar joints have higher erosion scores, and the 4th proximal interphalangeal (PIP), Scaphoid, Lunate, and Radius joints have higher joint space narrowing scores than other joints. These damage assessment results were similar to the results from the previous damage assessment model. @*Conclusions@#The joint space narrowing score is higher than the erosion score, suggesting that joint space narrowing precedes erosion. When checking the hand X-ray of rheumatoid arthritis patients, it is necessary to carefully check the scaphoid,lunate,radius and ulnar and 4th PIP joints, which relatively high radiographic damage scores. Also, the damage assessment model used in this study is relatively simple and does not show difference in analysis results from existing assessment models, so it can be considered for application in follow-up research.
RESUMEN
Objective@#. Fibromyalgia (FM) is a disorder characterized by chronic diffuse pain and enhanced pain response to stimuli and is caused by central sensitization. Tinnitus also is related to central sensitization. So we investigated the impact of tinnitus on FM. @*Methods@#. We included 22 FM patients with tinnitus and 25 FM patients without tinnitus. We assessed a range of symptoms using the Widespread Pain Index; Symptom Severity Score scale; Visual Analogue Scale of pain; and the Korean versions of the Fibromyalgia Impact Questionnaire (FIQ), the Insomnia Severity Index, and the Short-form Health Survey (SF-36). Information about the severity of tinnitus in FM patients was evaluated using the Korean version of the Tinnitus Handicap Questionnaire (THQ-K). @*Results@#. There were significant differences between the group that had mild tinnitus (THQ＜38) and the group that had moderate-to-severe tinnitus (THQ≥38) for FIQ score (p=0.025) and for the physical functioning (p=0.003), social functioning (p=0.035), and mental health (p=0.017) components of the SF-36. Also, after dividing patients into 2 groups according to insomnia severity, significant differences were observed in FIQ score (p=0.002) and in body pain (p=0.001), general health (p=0.008), vitality (p=0.003), social functioning (p=0.003), role limitation due to emotional condition (p=0.001), and mental health (p＜0.001) components of the SF-36. @*Conclusion@#. The FM patients with severe tinnitus had more functional impairments and lower quality of life than those with mild tinnitus. Severe insomnia also was accompanied by worse health status and lower quality of life.
