Outcomes in acute ischemic stroke (AIS) depend critically on rapid and accurate early diagnosis in the emergency department. Traditional prehospital tools and large vessel occlusion–focused scales facilitate triage but have limited capacity to distinguish ischemic from hemorrhagic stroke, a distinction essential for acute-phase treatment decisions. Recent advances include mobile stroke units equipped with computed tomography (CT), point-of-care laboratories, and telemedicine systems, as well as the emergence of biomarkers that enable field-based diagnosis and faster initiation of therapy. In-hospital imaging strategies incorporating CT, CT perfusion, and magnetic resonance imaging (MRI)-based tissue clocks have expanded eligibility for endovascular thrombectomy to include patients with large-core infarction or unclear-onset wake-up strokes. Prolonged cardiac monitoring and high-resolution vessel wall MRI have improved the detection of embolic sources and high-risk atherosclerotic plaques. Artificial intelligence now supports rapid imaging interpretation, workflow optimization, and treatment selection. Tenecteplase, a novel thrombolytic, provides a practical alternative to alteplase with comparable safety and efficacy, while post-thrombectomy management emphasizes individualized blood pressure control. In patients with minor stroke or high-risk transient ischemic attack, short-term dual antiplatelet therapy reduces early recurrence, and early initiation of lipid-lowering agents after AIS may stabilize vulnerable plaques and enhance vascular outcomes. Collectively, these innovations represent a shift toward integrated, time-sensitive, and precision-based AIS care spanning prehospital assessment, emergency department management, and post-reperfusion management.

Use of biomarkers in the early diagnosis of Ischemic Stroke: A Systematic Review
Close
Objective
The diagnosis of acute ischemic stroke (AIS) is time-sensitive and reliant on neuroimaging, which is not always immediately accessible. This systematic review aims to identify and evaluate bloodbased biomarkers with potential to support early diagnostic decision-making and facilitate prompt referral for confirmatory imaging and treatment.
Methods
Following the PRISMA guidelines, a systematic search of PubMed, Web of Science, LILACS, Medline, Scopus, Scielo, Epistemonikos and TRIP Data Base was conducted for primary studies published in the last five years. Original studies evaluating blood-based biomarkers collected within 12 hours of symptom onset for early diagnosis of AIS were included. The methodological quality of included studies was assessed using the QUADAS-2 tool.
Results
Ten studies met the inclusion criteria, investigating a range of biomarkers including proteins, non-coding RNAs, and lipids. Most studies were case-control in design, with overall risk of bias rated as low to moderate. Multi-marker panels combining biomarkers with clinical scales (e.g., D-dimer and GFAP with FAST-ED; AUC = 0.95), and lipidomics-based models (AUC = 0.968), demonstrated the highest diagnostic performance. Several individual non-coding RNAs also showed promising accuracy (AUC > 0.85).
Conclusion
Blood-based biomarkers, especially when used in multi-marker panels, demonstrate considerable potential as triage tools for early AIS diagnosis. Their application in point-of-care settings could reduce diagnostic uncertainty and accelerate time to treatment. However, prospective validation in real-world emergency environments is essential prior to clinical implementation.

Objective
Children are particularly vulnerable to heat-related illnesses due to their unique physiological and behavioral characteristics. Understanding the epidemiology and clinical features of heat-related illnesses in children is crucial for guiding targeted preventive measures and management strategies. This descriptive study aims to investigate the characteristics of pediatric patients with heat-related illness who were transferred to emergency departments in Japan.
Methods
This study was a secondary analysis of the Heatstroke Study, led by the Heatstroke and Hypothermia Surveillance Committee of the Japanese Association for Acute Medicine. This study included pediatric patients (<18 years) with heat-related illness transferred to emergency departments in the summer from 2017 to 2021. We summarized the circumstances of onset, clinical characteristics, and outcomes.
Results
Of the 3,154 registered patients, 146 children were included. Of them, 60% were male, with a median age of 15 years (interquartile range, 13–16 years). The most cases occurred in August (47%), and most (80%) were associated with sports activities and with outdoor settings (70%). Cases with a body temperature above 40 °C were rare (3%). Most cases were admitted to hospitals (75% to the general ward and 16% to the intensive care unit), and patients admitted to intensive care unit had altered consciousness with increased serum creatinine. There were two cases of mortality, both of which were out-of-hospital cardiac arrest.
Conclusion
Most pediatric cases with heat-related illness were middle or high school students, occurred in August, and were related to outdoor sports activity. Patients admitted to hospitals suffered altered consciousness, dehydration, and acute kidney injury.

Objective
Branch atheromatous disease (BAD) is a form of ischemic stroke that presents with imaging findings similar to those of lacunar infarction, but has a different pathogenesis and is known to cause progressive paralysis. Due to regional variations, the epidemiology of BAD is not well understood, and its relationship with the functional prognosis remains unclear. Using a comprehensive Japanese stroke database, we investigated its epidemiological characteristics and associations with functional outcomes. Methods In this multicenter cohort study, we retrospectively analyzed data from 27 hospitals that contributed to the Saiseikai Stroke Database (2013–2021). We used multivariable logistic regression to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CIs) of BAD compared with lacunar infarction (LI) for functional outcomes at discharge. Ischemic stroke caused by BAD or LI was included, and demographic characteristics and clinical data were evaluated and contrasted between BAD and LI. Results Of the 5,966 analyzed patients, 1,549 (25.9%) had BAD and 4,434 (74.1%) had LI. BAD was associated with worse functional outcomes (aOR, 2.77; 95% CI, 2.42–3.17; relative to LI) and extended hospital stays (median 19 days for BAD vs. 13 days for LI). Moreover, aggressive treatment strategies, including the use of argatroban and dual antiplatelet therapy, were more common in BAD patients. Conclusion BAD presented worse functional outcomes and longer hospital stays than LI, necessitating treatment plans that take into account its progression and prognosis.

A study on computed tomography cardiothoracic ratio in predicting left ventricular systolic dysfunction
Clin Exp Emerg Med. 2023;10(1):52-59.   Published online February 14, 2023
Close
Objective
A cardiothoracic ratio ≥0.50 is widely used as an indicator of cardiomegaly, but associations between the cardiothoracic ratio and left ventricular systolic dysfunction (LVSD) have not been investigated previously. We conducted this study to investigate the relationship between cardiothoracic ratio measured using computed tomography (CT) and left ventricular ejection fraction (LVEF), and to determine the optimal cardiothoracic ratio for predicting left ventricular systolic dysfunction (LVSD).
Methods
A retrospective cross-sectional study was performed using data from patients who underwent both chest CT and echocardiography at the emergency department from January 1 to December 31, 2021. The patients were classified as normal, or having mild, moderate, and severe LVSD based on their LVEF, and the cardiothoracic ratios of each group were compared. The receiver operating characteristic (ROC) curve analyses were used to identify the optimal cardiothoracic ratio for prediction of mild, moderate, and severe LVSD.
Results
The final study population included 444 patients. The median CT-measured cardiothoracic ratio was 0.54 for patients with normal LVEF, and 0.60 for patients with LVSD (P<0.001). The optimal CT-measured cardiothoracic ratios for predicting mild, moderate, and severe LVSD were 0.56, 0.59, and 0.60, and their areas under the ROC curve were 0.653, 0.690, and 0.680, and negative predictive values were 90%, 94%, and 98%, respectively.
Conclusion
The best cutoff value for a CT-measured cardiothoracic ratio suggestive of LVSD was 0.56, which is very different from the 0.50 value typically considered an abnormal cardiothoracic ratio. The CT-measured cardiothoracic ratio ≥0.56 can be used as a rough indicator of mild LVSD, and a ratio <0.60 can exclude severe LVSD with a high degree of confidence.

Objective
This study investigated the hospital diagnoses and characteristics of uncooperative prehospital patients suspected of acute stroke who could not undergo a prehospital stroke screening test (PHSST).
Methods
This retrospective observational study was conducted at a single academic hospital with a regional stroke center. We analyzed three scenario-based prehospital stroke screening performances using the final hospital diagnoses: (1) a conservative approach only in patients who underwent the PHSST, (2) a real-world approach that considered all uncooperative patients as screening positive, and (3) a contrapositive approach that all uncooperative patients were considered as negative.
Results
Of the 2,836 emergency medical services (EMS)-transported adult patients who met the prehospital criteria for suspicion of acute stroke, 486 (17.1%) were uncooperative, and 570 (20.1%) had a confirmed final diagnosis of acute stroke. The diagnosis in the uncooperative group did not differ from that in the cooperative group (22.0% vs. 19.7%, P=0.246). The diagnostic performances of the PHSST in the conservative approach were as follows: 79.5% sensitivity (95% confidence interval [CI], 75.5%–83.1%), 90.2% specificity (95% CI, 88.8%–91.6%), and 0.849 area under the receiver operating characteristic curve (AUC; 95% CI, 0.829–0.868). The sensitivity and specificity were 83.3% (95% CI, 80.0%–86.3%) and 75.2% (95% CI, 73.3%–76.9%), respectively, in the real-world approach and 64.6% (95% CI, 60.5%–68.5%) and 91.9% (95% CI, 90.7%–93.0%), respectively, in the contrapositive approach. No significant difference was evident in the AUC between the real-world approach and the contrapositive approach (0.792 [95% CI, 0.775–0.810] vs. 0.782 [95% CI, 0.762–0.803], P>0.05).
Conclusion
We found overestimation (false positive) and underestimation (false negative) in the uncooperative group depending on the scenario-based EMS stroke screening policy for uncooperative prehospital patients suspected of acute stroke.

Severe cerebral edema associated with exertional heat stroke is a major cause of death or disability. However, few studies on severe cerebral edema resulting from heat stroke have reported neuroradiological findings. Moreover, all the patients in these previous reports either died or remained severely disabled. Here, we report a case of exertional heat stroke with severe cerebral edema that probably developed or worsened due to delayed body temperature normalization. In contrast to previous reports, the patient showed complete clinical and neuroradiological recovery. This rare case suggests that severe cerebral edema could be reversed through meticulous supportive management. Moreover, it confirms the importance of rapid and effective cooling in heat stroke treatment.

Objective
The predictors of poor prognosis in heat stroke (HS) remain unknown. This study investigated the predictive factors of poor prognosis in patients with HS.
Methods
Data were obtained and analyzed from the health records of patients diagnosed with heat illness at Ajou university hospital between January 2008 and December 2017. Univariate and multivariate analyses were performed to identify the independent predictors of poor prognosis.
Results
Thirty-six patients (median age, 54.5 years; 33 men) were included in the study. Poor prognosis was identified in 27.8% of the study population (10 patients). The levels of S100B protein, troponin I, creatinine, alanine aminotransferase, and serum lactate were statistically significant in the univariate analysis. Multiple regression analysis revealed that poor prognosis was significantly associated with an increased S100B protein level (odds ratio, 177.37; 95% confidence interval, 2.59 to 12,143.80; P=0.016). The S100B protein cut-off level for predicting poor prognosis was 0.610 μg/L (area under the curve, 0.906; 95% confidence interval, 0.00 to 1.00), with 86% sensitivity and 86% specificity.
Conclusion
An increased S100B protein level on emergency department admission is an independent prognostic factor of poor prognosis in patients with HS. Elevation of the S100B protein level represents a potential target for specific and prompt therapies in these patients.

Emergency management of stroke has been directed at the delivery of recombinant tissue plasminogen activator (tPA) in a timely fashion. Because of the many limitations attached to the delivery of tPA and the perceived benefits accrued to tPA, its use has been limited. Mechanical thrombectomy, a far superior therapy for the largest and most disabling strokes, large vessel occlusions (LVOs), has changed the way acute strokes are managed. Aside from the rush to deliver tPA, there is now a need to identify LVO and refer those patients with LVO to physicians and facilities capable of delivering urgent thrombectomy. Other parts of emergency department management of stroke are directed at identifying and mitigating risk factors for future strokes and at preventing further damage from occurring. We review here the most recent literature supporting these advances in stroke care and present a framework for understanding the role that emergency physicians play in acute stroke care.

Dural sinus thrombosis (DST), or cerebral venous thrombosis, is an uncommon cause of stroke. It has a variable presentation, and the symptoms and signs can be non-specific. The diagnosis of DST can be difficult to make and is often delayed or missed. Computed tomography venography or magnetic resonance venography are the typical imaging modalities used to diagnose DST. However, computed tomography venography and magnetic resonance venography both have limitation for emergency department patients. In this article, we report the use of point-of-care ultrasound to facilitate the diagnosis of DST.

Approach to dizziness in the emergency department
Clin Exp Emerg Med. 2015;2(2):75-88.   Published online June 30, 2015
Close
Acute dizziness/vertigo is among the most common causes for visiting the emergency department. The traditional approach to dizziness starts with categorizing dizziness into four types: vertigo, presyncope, disequilibrium, and nonspecific dizziness. However, a recently proposed approach begins with classifying dizziness/vertigo as acute prolonged spontaneous dizziness/vertigo, recurrent spontaneous dizziness/vertigo, recurrent positional vertigo, or chronic persistent dizziness and imbalance. Vestibular neuritis and stroke are key disorders causing acute prolonged spontaneous dizziness/vertigo, but the diagnosis of isolated vascular vertigo has increased by virtue of developments in clinical neurotology and neuroimaging. However, a well-organized bedside examination appears more sensitive than brain imaging in diagnosing strokes presenting with acute dizziness/vertigo. A detailed history is vital to diagnose recurrent spontaneous dizziness/vertigo since confirmatory diagnostic tests are usually unavailable. Isolated positional vertigo is usually caused by benign paroxysmal positional vertigo, which can be treated at the bedside. In recent years, marked progress has occurred in the evaluation/management of acute dizziness/vertigo. However, even with developments in imaging technology, the diagnosis of acute dizziness/vertigo largely relies on bedside examination.

Objective
To investigate differences in the effect of intravenous (IV) thrombolysis regarding the mismatch of diffusion-weighted imaging–fluid-attenuated inversion recovery (DWI-FLAIR) among acute ischemic stroke patients who visited the emergency department (ED) within 3 hours from the onset of symptoms.
Methods
Among ED patients presenting with an acute ischemic stroke between January 2011 and May 2013 at a tertiary hospital, those who underwent magnetic resonance imaging before IV thrombolytic therapy were included in this retrospective study. Patients were divided into DWI-FLAIR mismatch and match groups. National Institutes of Health Stroke Scale (NIHSS) scores obtained initially, 24 hours after thrombolytic therapy, and on discharge, and early neurologic improvement (ENI) and major neurologic improvement (MNI) were compared.
Results
During the study period, 50 of the 213 acute ischemic stroke patients who presented to the ED were included. The DWI-FLAIR mismatch group showed a statistically significantly greater reduction in NIHSS both at 24 hours after thrombolytic therapy and upon discharge than did the match group (5.5 vs. 1.2, P<0.001; 6.0 vs. 2.3, P<0.01, respectively). Moreover, ENI and MNI were significantly greater for the DWI-FLAIR mismatch group than for the match group (27/36 vs. 2/14, P<0.001; 12/36 vs. 0/14, P=0.012, respectively).
Conclusion
Among acute ischemic stroke patients who visited the ED within 3 hours from the onset of symptoms, patients who showed DWI-FLAIR mismatch showed a significantly better response to IV thrombolytic therapy than did the DWI-FLAIR match group in terms of neurologic outcome.

Heat stroke is caused by losing control of one’s body temperature. It can be life threatening without proper treatment. In this case report, we describe a heat stroke patient treated with an external-cooling device, which is commonly used for therapeutic hypothermia after cardiac arrest. A 67-year-old woman was found unconscious with spontaneous breathing in a sauna. Her body temperature was 40.5°C when she arrived at the emergency department, and she was diagnosed with heat stroke. At seven hours after applying the Arctic Sun Temperature Management System (Medivance), her body temperature declined to 36.5°C, with neurologic improvement (Glasgow Coma Scale score increased from 3 to 12). She was admitted to an intensive care unit and discharged 14 days after admission without any neurological sequelae. In conclusion, an external-cooling device can be used effectively for heat stroke, in addition to therapeutic hypothermia after cardiac arrest.
