Emphysematous pyelonephritis (EPN) is a necrotizing infection of the renal parenchyma and its surrounding tissues that results in the accumulation of gas in the renal parenchyma, collecting system or perinephric tissue. EPN is a potentially life-threatening condition, which is most commonly associated with poorly controlled diabetes. We describe a case of emphysematous pyelonephritis associated with emphysematous ureteritis and cystitis in a 68-year-old diabetic woman, who was cured with medical treatment and surgical intervention.

Acute generalized exanthematous pustulosis is a rare, drug-induced disease that is occasionally accompanied by acute renal failure. It is characterized by the abrupt onset of widespread pustules on an erythematous base and rapid spontaneous healing. We report a case involving a 47-year-old male who presented with exanthematous pustules after taking medication. Azotemia was found in the resulting blood test. We were able to achieve the final diagnosis by skin biopsy. After instructing the patient not to take the previous medication, oral steroids were prescribed. He recovered within 2 weeks with just desquamations remaining.

Internal iliac artery aneurysm (IIAA) is a type of abdominal aneurysm that is a rare cause of lower urinary tract symptoms because of its anatomic location. If diagnosed after rupture, it can be lethal and surgery is mandatory. A 57-year-old male presented with acute urinary retention and syncope. An intra-abdominal mass initially thought to be an aneurysm was apparent by ultrasound. A computed tomography scan of the abdomen confirmed an internal iliac artery aneurysm accompanied by rupture. The patient was discharged without any complications within 20 days after receiving a vascular graft and resection of the aneurysm.

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.

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.

OBJECTIVE: The aim of this study was to identify the clinical characteristics and risk factors associated with the admission of patients in the emergency department (ED) within 30 days after discharge. METHODS: A retrospective, observational study was conducted on adult patients presenting with abdominal pain to the ED of a single, urban, university hospital, between January 2014 and December 2015, who revisited the ED within 30 days after discharge. Data was collected on the emergency severity index level, time to contact doctors, physical examination, laboratory tests, use of computed tomography (CT), and patient disposition on revisitation. The primary outcome was hospital admission following an ED revisit in the 30-day period after the first visit. RESULTS: During the study period, 19,480 patients visited the ED with the chief complaint of abdominal pain, and 13,577 were discharged. A total of 251 patients (1.29%) revisited the ED within 30 days, of which 89 were eligible for the study. The primary outcome was associated with not performing a CT scan on the initial visit and an increased C-reactive protein (CRP) value. Receiver operating characteristic curve analysis showed that a cut-off baseline CRP value of >0.35 mg/dL can predict the primary outcome with a sensitivity and specificity of 75% and 62.1%, respectively (area under the curve, 0.701; 95% confidence interval, 0.569–0.833; P=0.007). CONCLUSION: An increased CRP value and not performing abdominal CT were associated with a higher rate of admission following ED revisits of patients with abdominal pain. Future prospective studies on the role of abdominal CT imaging in patients presenting to the ED with abdominal pain will be needed.

Objective: To evaluate the predictive performance of optic nerve sheath thickness (ONST) on the outcomes of traumatic brain injury (TBI) and to compare the inter-observer agreement To evaluate the predictive performance of optic nerve sheath thickness (ONST) for traumatic brain injury (TBI) and to compare the predictive performance and inter-observer agreement between ONST and optic nerve sheath diameter (ONSD) on facial computed tomography (CT). Methods: We retrospectively enrolled patients with a history of facial trauma and who underwent both facial CT and brain CT. Two reviewers independently measured ONST and ONSD of each patient using facial CT images. Final brain CT with clinical outcome was used as the reference standard for TBI. Multivariate logistic regression analyses, receiver operating characteristic (ROC) curves, and intraclass correlation coefficients were used for statistical analyses. Results: Both ONST (P=0.002) and ONSD (P=0.001) on facial CT were significantly independent factors to distinguish between TBI and healthy brains; an increase in ONST and ONSD values corresponded with an increase in the risk of TBI by 8.9- and 7.6-fold, respectively. The predictive performances of the ONST (sensitivity, 96.2%; specificity, 94.3%; area under the ROC curve, 0.968) and ONSD (sensitivity, 92.6%; specificity, 90.2%; area under the ROC curve, 0.955) were excellent and exhibited similar sensitivity, specificity, and area under the curve (P=0.18–0.99). Interobserver and intraobserver intraclass correlation coefficients for ONST were significantly higher than those for ONSD (all P<0.001). Conclusion ONST on facial CT is a feasible predictor of TBI and demonstrates similar performance and superior observer agreement than ONSD. We recommend using ONST measurements to assess the need for additional brain CT scans in TBI-suspected cases.

PURPOSE: To evaluate the association between neutrophil-to-lymphocyte ratio (NLR) and occurrence of aspiration pneumonia in drug intoxication (DI) patients in the emergency department (ED) and to evaluate the relationship between NLR and length of hospital admission/intensive care unit (ICU) admission. METHODS: A total of 466 patients diagnosed with DI in the ED from January 2016 to December 2017 were included in the analysis. The clinical and laboratory results, including NLR, were evaluated as variables. NLR was calculated as the absolute neutrophil count/absolute lymphocyte count. To evaluate the prognosis of DI, data on the development of aspiration pneumonia were obtained. Also, we evaluated the relationship between NLR and length of hospital admission and between NLR and length of ICU admission. Statistically, multivariate logistic regression analyses, receiver-operating characteristic (ROC) curve analysis, and Pearson's correlation (ρ) were performed. RESULTS: Among the 466 DI patients, 86 (18.5%) developed aspiration pneumonia. Multivariate logistic regression analysis revealed NLR as an independent factor in predicting aspiration pneumonia (odds ratio, 1.7; p=0.001). NLR showed excellent predictive performance for aspiration pneumonia (areas under the ROC curves, 0.815; cut-off value, 3.47; p < 0.001) with a sensitivity of 86.0% and a specificity of 72.6%. No correlations between NLR and length of hospital admission (ρ=0.195) and between NLR and length of ICU admission (ρ=0.092) were observed. CONCLUSION: The NLR is a simple and effective marker for predicting the occurrence of aspiration pneumonia in DI patients. Emergency physicians should be alert for aspiration pneumonia in DI patients with high NLR value (>3.47).
