Combination treatment of antiplatelet drugs containing aspirin and clopidogrel reduces systemic ischemic events after percutaneous coronary intervention (PCI) in high risk patients. However, this combination treatment of antiplatelet drugs is associated with increased risk of nonfatal and fatal bleeding. Diffuse alveolar hemorrhage after PCI is a rare complication that has been mostly reported in association with glycoprotein IIb/IIIa inhibitors. We report the case of a 62-year-old man who presented with ST elevation myocardial infarction and suffered a diffuse alveolar hemorrhage after clopidogrel use following primary PCI.

OBJECTIVE: Posttraumatic embitterment disorder (PTED) is characterized by states of “embitterment”, characteristically similar to “Hwa-byung”, which is a Korean culture-bound syndrome. The present study aimed to assess diagnostic relationships between PTED and Hwa-byung. METHODS: A total of 290 participants completed our survey. PTED and Hwa-byung were diagnosed using a diagnostic interview and scale. Scales for depression, suicide ideation, and anger were used for evaluation. Fisher's exact tests and Mann-Whitney U tests were performed to evaluate diagnostic overlap between PTED and Hwa-byung, and associations of scale scores for depression, suicide ideation, and anger between the PTED, Hwa-byung, and non-diagnosed groups. Associations of these scales between the depressive and non-depressive groups, and suicidal and non-suicidal groups were also evaluated. RESULTS: Among the participants, 1.7% of the sample fit the diagnostic criteria for PTED and 2.1% fit the criteria for Hwa-byung. No individual fit the criteria for both. Anger scores were significantly higher in the Hwa-byung group than in the non-diagnostic group. There were not any significant differences in anger scores between the PTED and non-diagnostic groups. Depression scores were significantly higher in the PTED than in the non-diagnostic groups. In contrast, no significant differences were observed between depression scores in the Hwa-byung and non-diagnostic groups. CONCLUSION: These results suggest that PTED may be a disorder category that is distinct from Hwa-byung.

OBJECTIVES: The aim of this study was to compare the coping strategies among healthy controls, psychotic and neurotic patients and to evaluate the predictors of suicidal ideation. METHODS: The study population consisted of 115 outpatients in Ulsan University Hospital and 160 healthy controls. They filled out self-report questionnaires including demographics and validated psychiatric scales for depression, perceived stress, coping strategies, and suicide ideation. An analysis of the covariance was used to compare the clinical data among the groups. Stepwise multiple regression analysis was performed to estimate the effects of coping strategies and depression on the risk for suicidal ideation. RESULTS: Compared to the controls, the psychosis group used less active coping, and the neurosis group used more self-blame coping strategies. In healthy controls, suicidal ideation was predicted by depression, female gender, and using more self-blame coping. Although planning in psychosis was a protective factor, acceptance and self-blame in psychosis and behavioral disengagement in neurosis was a risk factor for suicidal ideation. CONCLUSION: Patients with psychotic and neurotic disorders use different coping strategies to deal with their distress and some of those are risk factors for suicidal ideation. Therefore, improving coping skills will be helpful for preventing suicide by alleviating the levels of stress and providing more effective emotion regulation.

Carbon monoxide (CO) is a well-known chemical asphyxiant, which causes tissue hypoxia with prominent neurological and cardiovascular injury. After exposure to CO, several cardiac manifestations have been reported, including arrhythmias, acute myocardial infarction, and pulmonary edema. However, an ST elevation myocardial infarction (STEMI) due to CO poisoning is a very rare presentation, and the treatment for STEMI due to CO poisoning is not well established. Here, we report a rare case of STEMI complicated by increased thrombogenicity secondary to acute CO poisoning and complete revascularization after antithrombotic treatment.

Background: and Purpose The wearing-off (WO) phenomenon is the most common motor complication in advanced Parkinson’s disease (PD), but its identification remains challenging. The 9- and 19-item Wearing-off Questionnaires (WOQ-9 and WOQ-19) are self-assessment tools for motor and nonmotor symptoms that are widely used for WO screening. We produced Korean versions of the WOQ-19 and WOQ-9 (K-WOQ-19 and K-WOQ-9) and investigated their validity and reliability. Methods: We used the translation–back translation method to produce K-WOQ-19 and KWOQ-9, which were self-administered by 124 patients with PD. We conducted in-depth 10-minute interviews for confirming the presence of the WO phenomenon, and then stratified the participants into groups with and without WO. Diagnostic accuracy was assessed by analyzing receiver operating characteristic curves. Concurrent validity was assessed using the Movement Disorder Society–Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) and the Hoehn and Yahr stage with Spearman’s rank correlation analysis. Reliability was assessed based on test–retest Cohen’s kappa (κ) values and intraclass correlation coefficients (ICCs). Results: The optimal cutoff scores on the K-WOQ-19 and K-WOQ-9 for WO screening were 4 and 2, respectively. The test–retest ICCs of K-WOQ-19 and K-WOQ-9 were 0.943 and 0.938, respectively. Nineteen of the combined 20 items in K-WOQ-19 and K-WOQ-9 showed moderate-to-substantial agreement (κ=0.412–0.771, p<0.001). The scores on the translated scales were significantly correlated with MDS-UPDRS IV scores. Conclusions K-WOQ-19 and K-WOQ-9 are reliable and valid tools for detecting WO, with optimal cutoff scores of 4 and 2, respectively.

Purpose: The purpose of this study is to understand the actual status of fundamentals of nursing practice (FNP) education at nursing colleges, and the difficulties of FNP operation in the early stages of the COVID-19. Methods: This study used a descriptive design. Data collection was conducted from December 9, 2020 to January 31, 2021 using the self-report questionnaire method for a total of 95 nursing colleges. The questionnaire consisted of characteristics related to FNP, changes in FNP education, difficulties in operating FNP, and countermeasures in the COVID-19 situation. Results: Changes in FNP due to COVID-19 were distribution of practice places, reduction of the number of students, short-term intensive classes, and reduction of face-to-face practice. Most colleges conducted FNP face-to-face, but some schools showed that FNP was conducted non-face-to-face. The difficulties of operating FNP that instructors experienced induced concerns about a decrease in student competency due to lack of face-to-face practice and an unofficial increase in the number of teaching hours and physical demands on instructors due to the expansion of the division. Conclusion In order to develop the capabilities of nursing students in other pandemic situations in the future, it is necessary to find systematic coping strategy to reduce the burden of FNP instructors, and to develop non-face-to-face online practice contents and consumables for online practice.

Objective: To compare the therapeutic outcomes of laparoscopic hepatic resection (LHR) and laparoscopic radiofrequency ablation (LRFA) for single subcapsular hepatocellular carcinoma (HCC). Materials and Methods: We screened 244 consecutive patients who had received either LHR or LRFA between January 2014 and December 2016. The feasibility of LRFA in patients who underwent LHR was retrospectively assessed by two interventional radiologists. Finally, 60 LRFA-feasible patients who had received LHR and 29 patients who had received LRFA as the first treatment for a solitary subcapsular HCC between 1 cm and 3 cm were finally included. We compared the therapeutic outcomes, including local tumor progression (LTP), recurrence-free survival (RFS), and overall survival (OS) between the two groups before and after propensity score (PS) matching. Multivariable Cox proportional hazard regression was also used to evaluate the difference in OS and RFS between the two groups for all 89 patients. Results: PS matching yielded 23 patients in each group. The cumulative LTP and OS rates were not significantly different between the LHR and LRFA groups after PS matching (p = 0.900 and 0.003, respectively). The 5-year LTP rates were 4.6% and 4.4%, respectively, and OS rates were 100% and 90.7%, respectively. The RFS rate was higher in LHR group without statistical significance (p = 0.070), with 5-year rates of 78.3% and 45.3%, respectively. OS was not significantly different between the LHR (reference) and LRFA groups in multivariable analyses, with a hazard ratio (HR) of 1.33 (95% confidence interval, 0.12–1.54) (p = 0.818). RFS was higher in LHR (reference) than in LRFA without statistical significance in multivariable analysis, with an HR of 2.01 (0.87–4.66) (p = 0.102). Conclusion There was no significant difference in therapeutic outcomes between LHR and LRFA for single subcapsular HCCs measuring 1–3 cm. The difference in RFS should be further evaluated in a larger study.
