ABSTRACT
Monoclonal antibodies are pure antibodies that react to a specific epitope. Plasmapheresis is a treatment that separates and eliminates disease-causing substances before replacing the blood with plasma. Plasmapheresis has insufficient evidence for treating new-onset refractory status epilepticus (NORSE). Sequential plasmaphereses gradually improved a female cryptogenic NORSE patient who did not benefit from monoclonal antibody treatment.
ABSTRACT
Background@#Non-invasive painless signaling therapy (NPST) is an electro-cutaneous treatment that converts endogenous pain information into synthetic non-pain information. This study explored whether pain improvement by NPST in failed back surgery syndrome (FBSS) patients is related to cerebral modulation. @*Methods@#Electroencephalography (EEG) analysis was performed in 11 patients with FBSS. Subjects received daily NPST for 5 days. Before the first treatment, patients completed the Brief Pain Inventory (BPI) and Beck Depression Inventory and underwent baseline EEG. After the final treatment, they responded again to the BPI, reported the percent pain improvement (PPI), and then underwent post-treatment EEG. If the PPI grade was zero, they were assigned to the ineffective group, while all others were assigned to the effective group. We used standardized low-resolution brain electromagnetic tomography (sLORETA) to explore the EEG current-source distribution (CSD) associated with pain improvement by NPST. @*Results@#The 11 participants had a median age of 67.0 years, and 63.6% were female. The sLORETA images revealed a beta-2 CSD increment in 12 voxels of the right anterior cingulate gyrus (ACG) and the right medial frontal area. The point of maximal CSD changes was in the right ACG. The alpha band CSD increased in 2 voxels of the left transverse gyrus. @*Conclusions@#Pain improvement by NPST in FBSS patients was associated with increased cerebral activity, mainly in the right ACG. The change in afferent information induced by NPST seems to be associated with cerebral pain perception.

ABSTRACT
Concern for patient safety underlies the need for interprofessional education (IPE). One way to measure the effectiveness of IPE is by measuring attitude change toward other healthcare professionals; however, there are currently no valid Korean tools to measure such a change in attitudes. Therefore, this study aims to develop and test a Korean version of the Interprofessional Attitudes Scale (IPAS). The original IPAS was translated into Korean according to the World Health Organization’s guidelines after obtaining permission from the article’s corresponding author. A total of 414 questionnaires were collected from third- and fourth-year medical and nursing students at four Korean institutions in December 2018. To analyze the validity of the Korean IPAS, exploratory and confirmatory factor analyses were conducted. Cronbach’s α was used to evaluate reliability. Results from the exploratory factor analysis identified four functions: teamwork, community-centeredness, patient-centeredness, and respect for diversity. Significant cross-correlations were found among the four functions (r=0.438–0.631, p<0.001) along with overall reliability (Cronbach’s α=0.929) and reliability of each subfactor (Cronbach’s α=0.804–0.897). This study verified the validity and reliability of the Korean version of the IPAS, so this scale can be used in the future to measure the effectiveness of IPE in Korea.
ABSTRACT
Purpose@#This study aims to understand the characteristics of smart device-based testing (SBT) by comparing the typical characteristics of students’ satisfaction with SBT, its usefulness, advantages, and disadvantages when compared with existing testing methods. @*Methods@#A total of 250 students from the first to third year were selected as the final targets of the study and the questionnaire was developed by faculty members who participated in the survey from the start of the SBT. The total number of questions is 12, and the questionnaire used a 4-point scale. The data obtained were analyzed using the IBM SPSS ver. 23.0 (IBM Corp., Armonk, USA). @*Results@#Answers to the “satisfaction with SBT” were generally negative, while answers to the “usefulness of SBT” were generally positive. There was no difference in satisfaction across gender and smart device ownership, whereas there were significant differences across years. With reference to the usefulness of SBT, students responded positively, while about the overall configuration and completeness of SBT, students responded negatively. Students also seemed to show a greater preference toward the pencil-paper test. @*Conclusion@#On the other hand, students generally thought that SBT helped to assess medical knowledge better and was a more objective method of knowledge assessment than a pencil-paper test. We believe that students preferred the traditional paper-pencil test due to their unfamiliarity with SBT. We believe that an appropriate and careful remedy for drawbacks of the SBT will have a significant impact in the accumulation of actual clinical knowledge and in the improvement of practical skills for medical students.
ABSTRACT
Background@#and Purpose: The increased demand for donor organs has made it crucial to keep the organs of patients with impending brain death (PWIBDs) suitable for transplantation during the process of determining brain death. This study aimed to identify the time taken to determine brain death (TT-BD) in PWIBDs and the associated influencing factors. @*Methods@#This study analyzed data collected by the Korean Organ Donation Agency from 15 hospitals in the Yeongnam region of South Korea. There were 414 PWIBDs eligible for inclusion in this study. The data consisted of the TT-BD for PWIBDs and the potential variables influencing the TT-BD. @*Results@#The mean age of the 414 PWIBDs was 48.9 years, and 120 of them were female (29.0%). The mean TT-BD was 8.5 days. The presence of spontaneous movements (SMs) and craniotomy significantly affected the TT-BD. The mean TT-BDs were 13.9 and 8.2 days in the PWIBDs with and without SMs, respectively, and 9.8 and 8.0 days in the PWIBDs with and without craniotomy, respectively. @*Conclusions@#The SMs in PWIBDs and a craniotomy performed immediately before starting the process of determining brain death seem to be related to lengthening the TT-BD.
ABSTRACT
Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are the most severe cutaneous drug hypersensitivity reactions, which are unpredictable adverse drug reactions. SJS/TEN is associated with significant mortality and morbidity; however, effective treatment is difficult. Mesenchymal stem cells (MSCs) are well-known for their anti-inflammatory and tissue regeneration properties. The purpose of the present study was to verify whether MSCs could be applied for the treatment of SJS/TEN. We developed an SJS/TEN mouse model using peripheral blood mononuclear cells from a lamotrigine-induced SJS patient. MSCs were injected into the model to verify the treatment effect. In SJS model mice treated with MSCs, ocular damage rarely occurred, and apoptosis rate was significantly lower. We demonstrated a therapeutic effect of MSCs on SJS/TEN, with these cells presenting a potential novel therapy for the management of this disorder.
ABSTRACT
Purpose@#In pulmonary oligometastases from colorectal cancer (POM-CRC), the primarily recommended local therapy is metastasectomy. Stereotactic body radiotherapy (SBRT) is another local therapy modality that is considered as an alternative option in patients who cannot undergo surgery. The purpose of this meta-analysis is to demonstrate the effects of SBRT on POM-CRC by integrating the relevant studies. @*Materials and Methods@#The authors explored MEDLINE, EMBASE, Cochrane Library, Web of Science, and SCOPUS, and selected studies including patients treated with SBRT for POM-CRC and availability of local control (LC) or overall survival (OS) rate. In this meta-analysis, the effect of SBRT was presented in the form of the LC and OS rates for 1, 2, 3, and 5 years after SBRT as pooled estimates, and the frequency of pulmonary toxicity of grade 3 or higher after SBRT (PTG3-SBRT). @*Results@#Fourteen full texts among the searched 4,984 studies were the objects of this meta-analysis. The overall number of POM-CRC patients was 495 as per the integration of 14 studies. The pooled estimate LC rate at 1, 2, 3, and 5 years after SBRT was 81.0%, 71.5%, 56.0%, and 61.8%, and the OS rate was 86.9%, 70.1%, 57.9%, and 43.0%, respectively. The LC and OS rates gradually declined until 3 years after SBRT in a similar pattern. Among the 14 studies, only two studies reported PTG3-SBRT as 2.2% and 10.8%, respectively. @*Conclusion@#For POM-CRC, SBRT is an ablative therapy with a benefit on LC and OS rates and less adverse effects on the lung.
ABSTRACT
BACKGROUND: Brain death is a clinical diagnosis that implies irreversible loss of function of the entire brain, including the brainstem and both hemispheres. Based on previous reports, it is not rare for reflex and spontaneous movements to occur in patients during the process of determining brain death. However, reports of the frequency and common types of these movements vary from study to study. Thus, we evaluated adult patients with impending brain death in Korea to determine the frequency and characteristics of reflex and spontaneous movements.METHODS: Brain dead patients who were admitted to 15 hospitals in the Yeongnam region (Southeast) of Korea were recruited prospectively from January 2013 to September 2016. All patients met the criteria for brain death as established by the Korea Medical Association. All body movements occurred during the process of diagnosing brain death and were assessed by physicians and trained organ transplant coordinators. The frequency and characteristics of these movements were identified and the demographic and clinical factors of impending brain dead patients with and without these movements were compared.RESULTS: A total of 436 patients who met the criteria for brain death were enrolled during the study period. Of these patients, 74 (17.0%) exhibited either reflex or spontaneous movements. Of this subset, 45 (60.8%) exhibited reflex movements only, 18 (24.3%) exhibited spontaneous movements only, and 11 (14.9%) exhibited both reflex and spontaneous movements. The most common reflex movements were the flexor/extensor plantar response and spinal myoclonus. Of the 74 patients, 52 (70.3%) exhibited one movement of the same pattern and 22 (29.7%) exhibited two or more different movement patterns. In addition, 45 (60.8%) exhibited these movements only on a limited area of the body with the leg being most common (n = 26, 57.8%). Patients with hypoxic brain damage and a higher systolic blood pressure exhibited significantly more reflex or spontaneous movements.CONCLUSION: Movements associated with brain dead patients are not rare and thus an awareness of these movements is important to brain death diagnosis. Physicians who perform brain death examinations should understand the frequency and characteristics of these movements to reduce delays in determining brain death.
ABSTRACT
Objective@#This study was evaluated the behavior intention of emergency medicine residents before and after education using a vignette case about professionalism, particularly in physician impairment. The residents’ reaction to this type of education was evaluated. @*Methods@#Thirty-four residents from five teaching hospitals participated in this education program consisting of lecture and discussion using cases. They wrote their behavioral intention and their opinions before and after education. Their satisfaction and reaction to the education experience were also collected. @*Results@#The frequencies of the common reasons for the action or the basis of the judgment, concerns during decision making, and desired help were similar, but their action decisions changed into more systemic and reasonable ones after the education. They had fewer learning experiences of non-clinical skills and were satisfied with this type of professionalism education. Furthermore, they felt the importance and educational needs of professionalism beyond this topic and would cope with similar problem situations the way they learned in this education. @*Conclusion@#In the professionalism education using the case discussion of impairment and self-monitoring, little had changed in the participants’ reasons for the action, concerns when decision making, and desired help, but their behavior intentions changed as they learned. This study provided the opportunity to recognize the importance of professionalism, patient safety, and peer relationship. Small group discussions using the vignette case can be suggested to provide professionalism education for the emergency medicine residents.

ABSTRACT
PURPOSE@#This study investigated the attitudes of Korean medical students about patient safety to determine which perspectives required increased focus in terms of educational development.@*METHODS@#Attitudes were assessed using the Patient Safety Questionnaire, a tool designed to measure attitudes toward patient safety among medical students. Questionnaires were distributed to 580 clinical year students across four medical schools in December 2018.@*RESULTS@#A total of 300 returned questionnaires were used in the final analysis. More than half of all respondents agreed (i.e., gave more than 4 out of 7 points) with most items and thoroughly considered the concept of patient safety. However, many students misperceived several items (e.g., professional incompetence as a cause of errors, disclosure responsibility, the importance of patient safety in the curriculum, and situational awareness).@*CONCLUSION@#Attitudes toward patient safety are highly important due to their substantial impacts on behavioral decisions in the clinical setting. As such, patient safety education should be designed to place greater emphasis on proper attitude. This study's findings should be useful for medical instructors who wish to determine the appropriate areas of curricular focus.
ABSTRACT
BACKGROUND: Team-based learning is known for its effective and satisfying education methods in the study of various medical schools. This study was prepared to confirm the satisfaction of applying this team-based learning to the training course of emergency medical technician.METHODS: A total of 165 new members of the course of second grade National Emergency medical technician at 2019 were finally enrolled in the study. Data were collected with a self-administered questionnaire. The team-based learning method was organized with eight students per group to conduct pre-learning and then proceed to open book to encourage active discussion among individuals. The questionnaire consisted of questions about the satisfaction of the discussion process, such as whether the knowledge gained from the discussion was appropriate, and whether collaboration between colleagues was successful during the discussion, and about the benefits of team-based learning, how well knowledge transfer compared to existing lectures, and the replacement of existing lectures. The questionnaire used a Likert 5 point scale, and the data obtained were analyzed using the SPSS version 22.0.RESULTS: The overall rating of team-based learning was 7.8 ± 1.5 out of 10. Many students answered positively (88.5%) for benefits, while 87.9% responded positively to whether the knowledge transfer effect was better compared to existing lectures. In addition, the satisfaction of team-based learning was generally high, with more than 90 percent of education students giving positive answers to the replacement of other lectures with team-based learning.CONCLUSION: The learners gave positive answers to the satisfaction, usefulness and learning effects of team-based learning. Team-based learning is a discussion-based study, so it is a good way to improve communication skills. Since communication and teamwork are important in first aid activities, the characteristics of team-based learning could lead to improvements in first aid services, leading to high-quality emergency medical services.

Brain death is a clinical diagnosis that implies irreversible loss of function of the entire brain, including the brainstem and both hemispheres. It is not uncommon for reflex and spontaneous movements to occur in patients with impending brain death during the process of determining brain death. When physicians charged with judging brain death witness such movements during this period, unless they know how common these movements are and what they mean, it will be difficult for them to make an appropriate determination of brain death. Movements following brain death have been reported in previous studies of various types, including cohort studies and case series or reports. However, only a few studies have employed verified diagnostic tools and neurological examinations as a standard protocol when diagnosing brain death. According to previous reports, the frequency of these movements ranges from 19.2% to 75.0% of all brain death cases. These reports have also described which movements are commonly seen. However, it is difficult to determine conclusively where these movements originate, i.e., in the spinal cord or in the cerebral motor cortex, and how such information should be considered in determining brain death. Although limited information is available on the characteristics and pathophysiological mechanism of these movements, it will help physicians to diagnose brain death correctly if they obtain sufficient knowledge about them.

OBJECTIVE: This study investigated and compared the perspectives on emergency medicine (EM) professionalism competencies of medical students and EM residents. In addition, how they learned their EM professionalism was also investigated to develop the base of an educational program of professionalism in the field of EM. METHODS: Medical students in four medical colleges/schools and EM residents were recruited for the questionnaire. Regarding the importance and educational need for EM professionalism, 23 items for medical students and 59 items for EM residents were asked. The items were rated on a five point Likert scale. The perspectives of the two groups were compared. The learning methods for professionalism were investigated. RESULTS: A total of 198 medical students and 109 EM residents responded to the questionnaire. The residents responded with mean of 3.0 or more on all items, agreeing on the importance and educational need. On the other hand, the mean scale was less than 4.0 in communication and cooperation with society and social accountability. The students responded with a mean scale of 4.0 or more on all items and agreed on the importance and educational need. Of the 23 common items, there were differences between the two groups in 17 items, showing a higher mean value in the students. The most common methods of learning EM professionalism was bedside teaching during the clinical clerkship for students, and patient handover or board round for residents. CONCLUSION: EM residents tended to place more importance on medical care than social communication, cooperation, and ethical items. The most common learning method of EM professionalism was clinical practice-associated activities. The results of this study could help to develop a systematic and realistic educational program of EM professionalism in EM clerkship and resident training.

@#To date, there are no clear guidelines for treatment of cryptogenic new onset refractory status epilepticus (NORSE) syndrome. Immunotherapy was effective for some patients, but the initiation time was often somewhat late. We experienced two cryptogenic NORSE syndrome patients with favorable outcomes with early immunotherapy. A 59 years old male patient and a 58 years old female patient visited our hospital in status epilepticus, who were later diagnosed as cryptogenic NORSE after full evaluation. Since seizures were not controlled by two or more antiepileptic drugs in both patients, immunotherapy began on the fifth day of hospitalization. There was improvement on EEG and clinical symptoms, one or two days after initiation of immunotherapy. Early diagnosis of NORSE and early immunotherapy may result in favorable outcome.
ABSTRACT
Interprofessional education (IPE) can promote high-quality patient care and good medical outcomes through teamwork among health professionals. However, there are no valid measurements to prove the effectiveness of IPE in Korea. This study aimed to develop and test a Korean version of the Self-efficacy for Interprofessional Experimental Learning Scale (SEIEL). The original SEIEL was translated into Korean by two experienced medical professors, and 368 questionnaires were collected from medical and nursing students (third and fourth year). To analyze the validity of the Korean version of the SEIEL, an exploratory and confirmatory factor analysis was conducted. Cronbach's α was used to evaluate reliability. Results from the exploratory factor analysis identified two functions: “interprofessional collaboration†and “interprofessional team evaluation.†A significant cross-correlation was found between the two functions (r=0.690, p<0.001), with a Cronbach's α value of 0.932. The reliability and validity of the Korean version of the SEIEL was identified in this study. This tool can be helpful in measuring the effectiveness of IPE in Korea.
