A 62-year-old man with local recurrence of pancreatic cancer underwent his 17th infusion of contrast medium. He had no history of allergy and had not experienced any side effects from the contrast medium during any of the previous examinations. During infusion, he complained of nausea, followed by a loss of consciousness. ⋯ Kounis syndrome is the concurrence of acute coronary syndromes with conditions associated with mast cell activation, including allergic or hypersensitivity and anaphylactic or anaphylactoid insults. In cases of coronary vasospasm with shock due to contrast medium, supportive therapy using catecholamine, which has coronary vasodilator activity, and a steroid might be effective to treat the coronary vasospasm. Attention should therefore be paid to the patient's complaints, the findings of real-time cardiosonography, electrocardiograms, and the levels of cardiac markers to ensure a correct diagnosis and to achieve a good treatment outcome.

Brucellosis is a zoonotic infectious disease that is common around the world. Its clinical course demonstrates great diversity as it can affect all organs and systems. However, the central nervous system is rarely affected in the pediatric population. ⋯ In this article, we present the case of a 9-year-old girl who developed unilateral nerve paralysis as a secondary complication of neurobrucellosis and recovered without sequel after treatment. This case is notable because it is a very rare, the first within the pediatric population. Our article emphasizes that neurobrucellosis should be considered among the distinguishing diagnoses in every case that is admitted for nerve paralysis in regions where Brucella infection is endemic.

This study aims to better understand the patterns and factors associated with the use of emergency department (ED) services on high-volume and intensive (defined by high volume and high-patient severity) days to improve resource allocation and reduce ED overcrowding. ⋯ These findings offer inputs for reallocating resources and altering staffing models to more efficiently provide high-quality ED services and prevent overcrowding.

Case Reports
Lung ultrasound associated to capnography to verify correct endotracheal tube positioning in prehospital.
Endotracheal intubation is the “gold standard” of the control of airway patency but is associated with nonnegligible morbidity rates. A rapid detection of esophageal intubation is essential. Capnography is considered the reference technique for correct endotracheal tube (ETT) positioning confirmation. ⋯ During cardiopulmonary resuscitation, there was a sudden absence of end-tidal CO2 capnographic detection. Correct tube positioning could not be ascertained by auscultation because the environment had become extremely noisy. However, TM-mode (Time Motion--mode) lung ultrasound revealed bilateral pleural sliding during insufflation with the self-filling balloon, thus confirming correct ETT positioning.

Symptoms are compared among patients with coronary artery disease (CAD) admitted to the emergency department with or without acute coronary syndrome (ACS). Sex and age are also assessed. ⋯ In patients with CAD, shortness of breath and dizziness are more common in non-ACS, whereas prior percutaneous coronary intervention and chest or arm pain are important factors to include during ACS triage.
