PURPOSE: The purpose of this study was to investigate effects of providing written information for coronary artery disease on health behavior compliance related self-efficacy, knowledge of disease, anxiety, and educational satisfaction depending on patients' health literacy.METHODS: The participants in this study were 40 patients who underwent coronary angiography or coronary intervention, and depending on the level of health literacy 30 patients were high group and 10 patients were low group. Each group was evaluated on health behavior compliance related self-efficacy, knowledge of disease, anxiety, and educational satisfaction with providing written information.RESULTS: By providing written information in the group with high health literacy, there was a significant difference in health behavior compliance related self-efficacy, knowledge of disease, but there was no significant difference in anxiety variable. On the other hand, there was no significant difference in health behavior compliance related self-efficacy, knowledge of disease, and anxiety by providing written information in the group with low health literacy. Also, there was no significant difference in the educational satisfaction between high and low group of health literacy after providing written information.CONCLUSION: It is necessary to develop educational materials that can be applied to clinical nursing field with considering health literacy of patients with coronary artery disease. In addition to providing written information, it is also necessary to develop other educational intervention programs such as video and personalized counseling that may be helpful for coronary patients with low health literacy and investigate their effectiveness.

Background: We aimed to study the clinicopathologic and immunohistochemical (IHC) (CD117, c-Myc, and p53) characteristics, and overall survival of primary and secondary breast angiosarcoma (BAS). Methods: This was a retrospective study of BAS cases diagnosed between 1997 and 2020 at our institution. Hematoxylin and eosin-stained slides were reviewed for tumor morphology, margin status, and lymph node metastasis. CD117, p53, D2-40, CD31, and c-Myc IHC stains were performed on 11 viable tissue blocks. Additional clinical information was obtained from the electronic medical records. Results: Seventeen patients with BAS were identified. Of these, five (29%) were primary and 12 (71%) were secondary BAS, respectively. The median age at diagnosis for primary BAS was 36 years. The median age at diagnosis for secondary BAS was 67 years. The median time to secondary BAS development following radiotherapy was 6.5 years (range, 2 to 12 years). There was no significant difference between primary and secondary BAS in several histopathologic parameters examined, including histologic grade, necrosis, mitotic count, lymph node metastasis, and positive tumor margins. There was also no difference in CD117, p53, D2-40, CD31, and c-Myc expression by IHC between primary and secondary BAS. During a median followup of 21 months, primary BAS had two (40%) reported deaths and secondary BAS had three (25%) reported deaths. However, this difference in survival between both groups was not statistically significant (hazard ratio, 0.51; 95% confidence interval, 0.09 to 3.28; p = .450). Conclusions BAS is a rare and aggressive disease. No histologic, IHC (CD117, c-Myc, and p53), or survival differences were identified between primary and secondary BAS in this study.

The number of migrant workers is increasing worldwide every year, and their number and role in Korean society is also increasing. However, the poor conditions faced by migrant workers often become a social issue, and it is not uncommon for them to be the subject of forensic autopsies. This study aimed to investigate the current status of medicolegal autopsy on migrant workers in Korea. We collected data of medicolegal autopsies on migrant workers conducted in Korea from 2016 to 2020 by requesting data from the institutions performing medicolegal autopsy. We calculated the autopsy rate and analyzed manner of death and cause of death. The medicolegal autopsy rate for foreign deaths was 16.4%, which was more than five times higher than the autopsy rate for Korean deaths. By manner of death, 43.7% were natural death, 6.4% were homicides, 8.5% were suicides, 23.6% were accidental deaths, 2.7% were undetermined unnatural deaths and 15.0% were unknown. These results showed a high rate of homicide, accidental death, and unknown death compared to Korean. And the proportion of industrial accident deaths and sudden manhood death syndrome were high. Through this study, it was confirmed that medicolegal autopsies are performed at a relatively high frequency when migrant workers die, and the characteristics related to the deaths of migrant workers were identified.

Extrapontine myelinolysis is a demyelinating disorder usually caused by rapid correction of chronic hyponatremia. We present an 82-year-old female patient with general weakness, and severe hyponatremia (103 mEq/L) which was corrected 14 mEq/L during 21 hours. She was stuporous and presented status epilepticus. Brain T2-weighted image showed high signal intensities of bilateral thalami and electroencephalogram monitoring indicated right hemisphere lateralized periodic discharges, maximal in the right frontal region. This case shows that status epilepticus can occur in a patient of extrapontine myelinolysis involved bilateral thalami without pontine lesions.

Sudden death during or after percutaneous coronary intervention (PCI) could be led to potential medicolegal disputes. This study aimed to investigate the clinical and postmortem findings in PCI-related deaths-focusing on the current statusto inform preventive strategies against these fatalities. Forty-three cases were retrieved from the National Forensic Service's postmortem records between 2015 and 2021, and the corresponding postmortem findings and clinical information were analyzed. The analyses revealed a relatively consistent annual incidence of PCI-related deaths. Immediate deaths during or shortly after PCI occurred in 17 cases (39.5%), and delayed PCI-related deaths after discharge from the hospital occurred in 26 cases (60.5%). The causes of PCI-related deaths in the postmortem cases were categorized into four groups: PCI complications (11 cases, 26%), acute myocardial infarction (23 cases, 53%), ischemic heart disease (8 cases, 19%), and others (1 case, 2%). Postmortem examinations played a critical role in determining the cause of death and obtaining medical evidence, including pathological findings of the heart as well as those of coronary artery and stent insertion. Our findings suggest that a detailed examination of the heart, coronary arteries, stent status, and atherosclerosis in PCI-related deaths could help provide more accurate information as medical evidence and prevent/resolve potential medicolegal issues. Further, this could advance our understanding of PCI-related deaths and inform future preventive strategies.

Mycobacterium fortuitum is a rare pathogen, frequently found in water, soil, animals and plant materials. It can cause infections involving skin, soft tissue and skeletal system after direct inoculation of the pathogen through surgical traumas, punctures and injections. We report a case of infrapatellar bursitis caused by M. fortuitum in an immunocompetent, 42-year-old female, which occurred after bicycle trauma. She experienced marked improvement after surgical excision and debridement of the wound site and antimicrobial therapy.

Continuous renal replacement therapy (CRRT) has become the standard modality of renal replacement therapy (RRT) in critically ill patients. However, consensus is lacking regarding the criteria for discontinuing CRRT. Here we validated the usefulness of the prediction model for successful discontinuation of CRRT in a multicenter retrospective cohort. Methods: One temporal cohort and four external cohorts included 1,517 patients with acute kidney injury who underwent CRRT for >2 days from 2018 to 2020. The model was composed of four variables: urine output, blood urea nitrogen, serum potassium, and mean arterial pressure. Successful discontinuation of CRRT was defined as the absence of an RRT requirement for 7 days thereafter. Results: The area under the receiver operating characteristic curve (AUROC) was 0.74 (95% confidence interval, 0.71–0.76). The probabilities of successful discontinuation were approximately 17%, 35%, and 70% in the low-score, intermediate-score, and highscore groups, respectively. The model performance was good in four cohorts (AUROC, 0.73–0.75) but poor in one cohort (AUROC, 0.56). In one cohort with poor performance, attending physicians primarily controlled CRRT prescription and discontinuation, while in the other four cohorts, nephrologists determined all important steps in CRRT operation, including screening for CRRT discontinuation. Conclusion: The overall performance of our prediction model using four simple variables for successful discontinuation of CRRT was good, except for one cohort where nephrologists did not actively engage in CRRT operation. These results suggest the need for active engagement of nephrologists and protocolized management for CRRT discontinuation.
