Standardized modeling of cardiac arrest and cardiopulmonary resuscitation (CPR) is crucial to evaluate new treatment options. Experimental porcine models are ideal, closely mimicking human-like physiology. However, anteroposterior chest diameter differs significantly, being larger in pigs and thus poses a challenge to achieve adequate perfusion pressures and consequently hemodynamics during CPR, which are commonly achieved during human resuscitation. The aim was to prove that standardized resuscitation is feasible and renders adequate hemodynamics and perfusion in pigs, using a specifically designed resuscitation board for a pneumatic chest compression device. ⋯ Standardized cardiopulmonary resuscitation is feasible in a porcine model, achieving adequate hemodynamics and consecutive tissue perfusion of consistent quality.

Acalculia is defined as the inability to mentally manipulate numbers for simple calculations. It may occur in dementia, central nervous system (CNS) neoplasm, and stroke (Bermejo-Velasco and Castillo-Moreno, 2006). ⋯ We report the case of a 63-year-old male with a 1 day history of isolated acalculia that was found to have a left parietal lobe infarct with several smaller infarcts in the left occipital lobe. The diagnosis of stroke should be considered in all patients experiencing acute difficulty with mathematics, reading, or writing, even in the absence of other deficits.

We conducted this study to investigate whether ESI combined with qSOFA score (ESI+qSOFA) predicts hospital outcome better than ESI alone in the emergency department (ED). ⋯ The prognostic performance of ESI+qSOFA for in-hospital mortality was significantly higher than that of ESI alone. Within each subgroup, patients with positive qSOFA had higher in-hospital mortality compared to those with negative qSOFA.

To describe our experience with intravenous lidocaine (IVL) to manage pain of renal colic origin in the emergency department (ED). ⋯ Intravenous lidocaine has a potential of being used for patients presenting to the ED with a pain of renal colic origin as a primary analgesic or as a rescue. Although promising, this therapy will need to be studied in prospective randomized fashion and larger patients' population with underlying cardiac disease before it can be recommended for broad use in the ED.

There were few case reports discuss about iatrogenic chest wall hematoma. Although it is rare life threatening, it still can result in significant morbidity. A 68-year-old woman with histories of end-stage renal disease under regular hemodialysis and congestive heart failure was sent to our emergency department because of progression of ecchymosis over the anterior chest wall a few hours after hemodialysis. ⋯ Treating the underlying disease and discontinuing anticoagulation and antiplatelet agents should be considered. For iatrogenic chest wall hematoma, bleeding control should be the priority. Contrast-enhanced computed tomography could be arranged if there are no contraindications.
