The precise mechanism involved in DIC and delayed traumatic subarachnoid hemorrhage (DT-SAH) remains unclear in multiple-trauma patients. Hereby, we describe a polytraumatized patient with DIC who died due to DT-SAH. A 75-year-old female patient was admitted to our Emergency Department complaining of abdominal pain and drowsiness after a pedestrian accident. Her initial brain computerized tomography (CT) finding was negative for intracranial injury. However, her abdominal CT scan revealed a collection of retroperitoneal hematomas from internal iliac artery bleeding after a compressive pelvic fracture. This event eventually resulted in shock and DIC. An immediate angiographic embolization of the bleeding artery was performed along with transfusion and anti-thrombin III. Her vital signs were stabilized without neurological change. Fourteen hours after admission, she suddenly became comatose, and her follow-up brain CT scan revealed a dense DT-SAH along the basal cisterns with acute hydrocephalus. This event rapidly prompted brain CT angiography and digital subtraction angiography, which both confirmed the absence of any cerebrovascular abnormality. Despite emergency extraventricular drainage to reverse the hydrocephalus, the patient died three days after the trauma. This paper presents an unusual case of DT-SAH in a polytraumatized patient with DIC.

Background: Myasthenia gravis (MG) is a rare classic autoimmune disease where immunosuppressant therapies have been successful to reduce MG attributable mortality fairly well. However, patients with refractory MG (rMG) among the actively treated MG (aMG) are nonresponsive to conventional therapy and display high disease severity, which calls for further research. We aimed to determine survival, prognosis, and clinical feature of patients with rMG compared to non-rMG. Methods: Retrospective nationwide cohort study using Korea's healthcare database between 2002 and 2017 was conducted. Patients with rMG (n = 47) and non-rMG (n = 4,251) who were aged > 18 years, followed-up for ≥ 1 year, and prescribed immunosuppressants within 2 years after incident MG diagnosis were included. Patients with rMG were defined as administered plasma exchange or intravenous immunoglobulin at least 3 times per year after receiving ≥ 2 immunosuppressants. All-cause mortality, myasthenic crisis, hospitalization, pneumonia/ sepsis, and emergency department (ED) visits were measured using Cox proportional hazard models and pharmacotherapy patterns for rMG were assessed. Results: The rMG cohort included a preponderance of younger patients and women. The adjusted hazard ratio was 2.49 (95% confidence interval, 1.26–4.94) for mortality, 3.14 (2.25–4.38) for myasthenic crisis, 1.54 (1.15–2.06) for hospitalization, 2.69 (1.74–4.15) for pneumonia/sepsis, and 1.81 (1.28–2.56) for ED visits for rMG versus non-rMG. The immunosuppressant prescriptions were more prevalent in patients with rMG, while the difference was more remarkable before rMG onset rather than after rMG onset. Conclusion Despite the severe prognosis of rMG, the strategies for pharmacotherapeutic regimens were similar in those two groups, suggesting that intensive monitoring and introduction of timely treatment options in the early phase of MG are required.

BACKGROUND/OBJECTIVES: This study was conducted to evaluate the feasibility of a sodium reduction program at local restaurants through nutrition education and examination of the health of restaurant owners and cooks. SUBJECTS/METHODS: The study was a single-arm pilot intervention using a pre-post design in one business district with densely populated restaurants in Seoul, South Korea. The intervention focused on improving nutrition behaviors and psychosocial factors through education, health examination, and counseling of restaurant personnel. Forty-eight restaurant owners and cooks completed the baseline survey and participated in the intervention. Forty participants completed the post-intervention survey. RESULTS: The overweight and obesity prevalences were 25.6% and 39.5%, respectively, and 74.4% of participants had elevated blood pressure. After health examination, counseling, and nutrition education, several nutrition behaviors related to sodium intake showed improvement. In addition, those who consumed less salt in their baseline diet (measured with urine dipsticks) were more likely to agree that providing healthy foods to their customers is necessary. This study demonstrated the potential to reduce the sodium contents of restaurant foods by improving restaurant owners' and cooks' psychological factors and their own health behaviors. CONCLUSIONS: This small pilot study demonstrated that working with restaurant owners and cooks to improve their own health and sodium intake may have an effect on participation in restaurant-based sodium reduction initiatives. Future intervention studies with a larger sample size and comparison group can focus on improving the health and perceptions of restaurant personnel in order to increase the feasibility and efficacy of restaurant-based sodium reduction programs and policies.

OBJECTIVE: A small epidural hematoma (EDH) that has been diagnosed to be nonsurgical by initial brain computed tomography (CT) can increase in size and need surgical removal, resulting in a poor prognosis. However, there have been few studies, which focused delayed operated EDH. Therefore, we analyzed the clinical factors to determine the predicting factors of delayed operated EDH. METHODS: Between January 2011 and January 2014, 90 patients, who were admitted due to EDH, were enrolled in this study. None of the patients were indicated for operation initially. Based on the presence of surgery, we classified the patients into a delayed-surgery group (DG) and a non-surgical group (NG). Additionally, we analyzed them according to the following: time interval between the trauma and the initial CT, gender, age, medical history, drinking, change of mean arterial pressure (MAP), volume of EDH and other traumatic brain lesion. RESULTS: Among the 90 patients, the DG was 19 patients. Compared with NG, the DG revealed increased MAP, less presence of drinking, and a short time interval (DG vs. NG: +9.684 mm Hg vs. -0.428 mm Hg, 5.26% vs. 29.58%, 1.802 hours vs. 5.707 hours, respectively, p<0.05). Analyzing the time interval with receiver operating characteristic, there was 88.2% sensitivity and 68.3% specificity at the 2.05-hour cut-off value (area under the curve=0.854). CONCLUSION: According to our results, the time interval between the trauma and the initial CT along with blood pressure change are potential predicting factors in the cases of delayed operation of EDH.

Complex regional pain syndrome (CRPS) is a chronic neuropathic pain disorder. Pain catastrophizing, characterized by magnification, rumination, and helplessness, increases perceived pain intensity and mental distress in CRPS patients. As functional connectivity patterns in CRPS remain largely unknown, we aimed to investigate functional connectivity alterations in CRPS patients and their association with pain catastrophizing using a whole-brain analysis approach. Twenty-one patients with CRPS and 49 healthy controls were included in the study for clinical assessment and resting-state functional magnetic resonance imaging. Between-group differences in whole-brain functional connectivity were examined through a Network-based Statistics analysis. Associations between altered functional connectivity and the extent of pain catastrophizing were also assessed in CRPS patients. Relative to healthy controls, CRPS patients showed higher levels of functional connectivity in the bilateral somatosensory subnetworks (components 1~2), but lower functional connectivity within the prefronto-posterior cingulate (component 3), prefrontal (component 4), prefronto-parietal (component 5), and thalamo-anterior cingulate (component 6) subnetworks (p<0.05, family-wise error corrected). Higher levels of functional connectivity in components 1~2 (β=0.45, p=0.04) and lower levels of functional connectivity in components 3~6 (β=-0.49, p=0.047) were significantly correlated with higher levels of pain catastrophizing in CRPS patients. Higher functional connectivity in the somatosensory subnetworks implicating exaggerated pain perception and lower functional connectivity in the prefronto-parieto-cingulo-thalamic subnetworks indicating impaired cognitive-affective pain processing may underlie pain catastrophizing in CRPS.

BACKGROUND/AIMS: Noncardiac chest pain (NCCP) is substernal, squeezing chest pain, unrelated to the cardiac problem. Our study aimed to define the prevalence and clinical characteristics of reflux esophagitis in NCCP patients in Korea. MATERIALS AND METHODS: We reviewed medical records of patients who visited Department of Cardiology, St. Paul's Hospital due to chest pain and had normal coronary arteriography and who had received endoscopy within 6 months. Patients diagnosed with peptic ulcer or gastric cancer were excluded. The patients were classified into two groups according to their endoscopic results; the reflux esophagitis group and the control group. RESULTS: Two hundred seventeen NCCP patients were enrolled and 96 patients (44.2%) were diagnosed with reflux esophagitis: 68 patients (31.3%) with minimal change esophagitis; 26 patients (12.0%) with Los Angeles (LA) grade A; 2 patients (0.9%) with LA grade B. There were no patients with severe erosive reflux disease. There were no significantly different characteristics in the reflux esophagitis group and the control group. CONCLUSIONS: The prevalence of reflux esophagitis in NCCP patients in Korea was 44.2%. Most patients had mild reflux esophagitis.

PURPOSE: The Korean Society of Coloproctology holds its annual colorectal awareness month every September. This study analyzed the users and the contents of Korean tweets regarding colorectal cancer and estimated the transmissibility of the awareness campaign among Twitter users. METHODS: Prospective data collection was employed to accumulate Korean tweets containing the keywords "colorectal cancer," "colorectal cancer awareness campaign," "gold ribbon," and/or "love handle," from August 1 to September 30, 2014. Twitter users and contents were analyzed, and the credibility of information-sharing tweets throughout the study period was evaluated. RESULTS: In total, 10,387 tweets shared by 1,452 unique users were analyzed. As for users, 57.8% were individuals whereas 5.8% were organizations/communities; spambots accounted for a considerable percentage (36.4%). As for content, most tweets were spam (n = 8,736, 84.1%), repetitively advertising unverified commercial folk remedies, followed by tweets that shared information (n = 1,304, 12.6%) and non-information (n = 347, 3.3%). In the credibility assessment, only 80.6% of the information-sharing tweets were medically correct. After spam tweets had been excluded, a significant increase was seen in the percentage of information-sharing tweets (77.1% to 81.1%, P = 0.045) during the awareness campaign month. CONCLUSION: Most Korean tweets regarding colorectal cancer during the study months were commercial spam tweets; informative public tweets accounted for an extremely small percentage. The transmissibility of the awareness campaign among Twitter users was questionable at best. To expand the reach of credible medical information on colorectal cancer, public health institutions and organizations must pay greater attention to social media.

Purpose: The Korean Society of Coloproctology has been conducting Colorectal Cancer Awareness Campaign, also known as the Gold Ribbon Campaign, every September since 2007. The 2022 campaign was held through a metaverse platform targeting the younger age group under the slogan of raising awareness of early-onset colorectal cancer (CRC). This study aimed to analyze the impact of the 2022 campaign on a metaverse platform. Methods: Anonymized survey data were collected from participants in the metaverse campaign from September 1 to 15, 2022. The satisfaction score of the participants was evaluated by sex, age group, and previous campaign participation status. Results: During the campaign, 2,770 people visited the metaverse. Among them, 455 people participated in the survey (response rate, 16.4%). Approximately 95% of the participants reported being satisfied with the information provided by the campaign, understood the necessity of undergoing screening for and prevention of early-onset CRC, and were familiar with the structure of the metaverse. The satisfaction score for campaign information tended to decrease as the participants’ age increased. When the participants’ overall level of satisfaction with the metaverse platform was assessed, teenagers scored particularly lower than the other age groups. The satisfaction scores for CRC information provided in the metaverse, as well as the scores for recognizing the seriousness and necessity of screening for early-onset CRC, indicated a high positive tendency (P<0.001). Conclusion Most of the 2022 Gold Ribbon Campaign participants were satisfied with the metaverse platform. Medical society should pay attention to increasing participation in and satisfaction with future public campaigns.
