Comparative Study
Change in T/QRS ratio can be a supplementary diagnostic tool in predicting coronary artery disease in patients with NSTEMI.
Changes in the electrocardiographic findings, namely the ratio T sum to QRS sum (T/QRS ratio), between the initial electrocardiogram (ECG) and the baseline ECG have rarely been investigated in patients with non-ST elevation myocardial infarction (NSTEMI). Thus, we aimed to determine whether changes in various parameters on ECG, including T/QRS ratio, can assist in distinguishing between coronary artery disease (CAD) and NSTEMI without CAD with low to moderate risk. ⋯ Change in the most deviated T/QRS ratio in the regional leads on initial ECG from the T/QRS ratio in the same lead on remote ECG can assist in predicting CAD risk between patients with CAD and patients with no CAD in NSTEMI.

Early diagnosis of blunt cerebrovascular injury (BCVI) is among the most difficult challenges in trauma treatment. This study aimed to determine the optimal timing of computed tomographic angiography (CTA) screening for suspicious BCVI in patients with polytrauma. ⋯ For patients with polytrauma, performing brain CTA for BCVI screening in the first 24-h or after may not affect clinical outcome. Initial motor response is the sole indicator for outcome. Delaying the study for to the next 24-hour can be considered in such patients, when regarding hemodynamic stability, the dose of contrast medium, and the radiation exposure.

The utilization of CTA in management of gastrointestinal bleeding in a tertiary care center ED. Are we using it enough?
Gastrointestinal (GI) bleeding is a common patient presentation to the Emergency Department (ED) and the source can be difficult to diagnose. ⋯ We concluded that in light of its validation against these other diagnostic modalities, CTA may be underutilized in the care of patients with GI bleeding and should be studied further to study its impact on early risk stratification, treatment, and resource utilization.

Recent reports have described a secondary Multisystem Inflammatory Syndrome in Children (MIS-C) after a prior COVID-19 infection that often has features of Kawasaki disease (KD). Here, we report the case of a 36-year-old woman who presented to the emergency department hypotensive and tachycardic after 1 week of fevers, abdominal pain, vomiting and diarrhea, and was found to have the classic phenotype of complete Kawasaki's Disease including nonexudative conjunctivitis, cracked lips, edema of the hands and feet, palmar erythema, a diffuse maculopapular rash, and cervical lymphadenopathy. Initial laboratory studies were significant for hyponatremia, elevated liver function tests including direct hyperbilirubinemia, and leukocytosis with neutrophilia. ⋯ It suggests that the virulent strain of SARS-CoV-2 appears to cause a post-infectious inflammatory syndrome similar to KD in adults, as well as children. Our understanding of the myriad of COVID-19 symptoms and sequelae is rapidly evolving. We recommend physicians remain vigilant for inflammatory syndromes that mimic KD/KDSS which may warrant prompt treatment with IVIG and steroids.

To evaluate the demographic characteristics, endoscopy results, emerging complications and the final status of caustic intake cases admitted to our emergency department. ⋯ Corrosive substance intake is a rare but potentially devastating poisoning with high morbidity and mortality. Mucosal injury begins within minutes following corrosive intake. Therefore, early endoscopy is helpful in assessing the degree of injury and early discharge from hospital.
