Metacarpal fractures are common injuries, accounting for approximately 30% to 40% of all hand fractures and with a lifetime incidence of 2.5%. Traditionally regarded as an innocuous injury, metacarpal fractures tend to be associated with successful outcomes after closed reduction and immobilization. ⋯ We discuss the case of a 44-year-old woman presenting with multiple closed metacarpal fractures as a result of low-energy trauma, complicated by acute HCS. We review the presentation, clinical assessment, and optimal surgical management of acute HCS with reference to international literature.

Effect of intravenous fat emulsion therapy on glyphosate-surfactant-induced cardiovascular collapse.
Intravenous fat emulsion (IFE) therapy is an adjunct therapy administered to hemodynamically compromised patients with glyphosate-surfactant intoxication when they respond poorly to conventional therapies such as fluid resuscitation or vasopressors [1,2]. However, the use of IFE as an adjunct therapy in collapsed patients with glyphosate intoxication has not been reported previously. Here, we describe the case of a patient with glyphosate-surfactant–induced cardiovascular collapse who responded to IFE.

Emergency medicine setting is intrinsically prone to a greater risk of medical errors than other specialties. Cognitive errors are particularly frequent when the clinical decision-making process heavily relies on heuristics. ⋯ Our article demonstrates how emergency physicians' thinking may be affected by failed heuristics, through the description of 3 real clinical cases. We aimed to show how the proper use of a widespread and easy-learning technology, such as goal-directed, focused ultrasonography, may both counteract cognitive errors and favor the right interpretation of other examinations.

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.

Kounis syndrome (KS) is an acute coronary vasospasm after exposure to an allergen due to mast cell degranulation and existing mediators. Various drugs, conditions, and environmental exposures can cause KS. We presented 2 cases, 1 of whom had taken an antiflu drug (containing paracetamol, pseudoephedrine, and dextromethorphan). ⋯ His troponin was markedly elevated. These cases showed that there seems to be no correlation with ECG and troponin levels in KS. In addition, for patients in whom KS type 1 is expected without troponin elevation, noninvasive cardiac magnetic resonance imaging study seems to be appropriate for the diagnosis of KS.
