Extramedullary plasmacytoma (EMP) is a common plasma cell tumor often involving the upper aerodigestive tract. Although extremely rare, mediastinal involvement is possible. An 81-year-old man was presented to our emergency department with chest and back pain with weakness in both legs. Chest X-ray showed a large mass in the upper right mediastinum; subsequently, computed tomography and magnetic resonance imaging evaluated the mass. He was diagnosed with mediastinal EMP, which progressed to spinal cord compression. The patient was treated with radiotherapy and chemotherapy. Spinal cord compression, due to metastatic tumor, is an emergency clinical situation that requires prompt diagnosis and treatment. Emergency medicine physicians should be aware of the clinical presentation and complications associated with EMP.

Background The benefit of statin use after acute ST-segment elevation myocardial infarction (STEMI) has been well established, however, the influence of the timing of statin administration has not been elucidated. The objective of this study focused on early clinical outcomes after percutaneous coronary intervention (PCI). Methods This analysis of the Korea Working Group on Myocardial Infarction registry (KorMI) study included 3,584 STEMI patients (mean age, 63 ±13 years;male, 2,684, 74.9%) undergoing PCI from January 2008 to June 2009. Rates of major adverse cardiac events (MACE:all-cause death, recurrent MI, and target lesion revascularization) were compared among patients grouped according to statin therapy timing:I, both during and after hospitalization (n=2,653, 74%);II, only during hospita-lization (n=309, 8.6%);III, only after discharge (n=157, 4.4%);and IV, no statin therapy (n=465, 13%). Mean follow-up duration was 234 ± 113 days. Results Multivariate factors of statin use during hospitalization included prior statin use, multiple diseased vessels, final thrombolysis in myocardial infarction flow grade III, and low-density lipoprotein cholesterol level. At 6-month follow-up, groups III and IV had the highest MACE rates (2.3%, 3.9%, 5.1%, and 4.9%for groups I-IV, respectively, P=0.004). After adjusting for confounders, groups II-IV had a higher MACE risk than group I [hazard ratio (HR):3.20, 95%confidence interval (95%CI):1.31-7.86, P=0.011;HR:3.84, 95%CI:1.47-10.02, P=0.006;and HR:3.17, 95%CI:1.59-6.40, P=0.001;respectively]. Conclusions This study, based on the national registry database, shows early and continuous statin therapy improvs early outcomes of STEMI patients after PCI in real-world clinical prac-tice.

Objective: Troponin I is a cardiac biomarker to diagnose acute myocardial infarction and is known to be elevated in sepsis patients as well. Recent studies have shown a correlation between troponin I results the prognosis of sepsis patients. We attempted to correlate the serial measurements of high-sensitivity troponin I (Hs-TnI) results with the prognosis of sepsis patients visiting the emergency room (ER). Methods: We conducted a retrospective study of patients who visited the ER from December 2019 to May 2021 with a diagnosis of infectious disease and a quick Sequential Organ Failure Assessment (qSOFA) score of over two. Those who had been administered the 3-hour interval Hs-TnI test were selected and the difference between two Hs-TnI (delta Hs-TnI) results were correlated with the prognosis of the patient. Results: A total of 76 patients were included in the study, including 56 28-day survivors and 20 28-day non-survivors. The delta Hs-TnI was higher in the non-survivor group and associated with a poorer prognosis (P=0.004). Multivariate logistic regression was used, and log(delta Hs-TnI) showed an odds ratio (OR) of 2.227 (95% confidence interval [CI], 1.171-5.818), (P=0.023) while the Sequential Organ Failure Assessment (SOFA) score showed an OR of 1.478 (95% CI, 1.229-1.777) (P<0.001). The area under the curve (AUC) was calculated using the receiver operating characteristic curve and the AUC for the SOFA score was 0.893 and that from the log(delta Hs-TnI) was 0.724. Conclusion An increase in delta Hs-TnI is correlated with the poorer prognosis of sepsis patients. Hence, it would be useful to check the serial Hs-TnI to predict the 28-day outcome of sepsis patients visiting the ER.
