Patients presenting unconscious may reasonably be categorized as suffering from a metabolic or structural condition. ⋯ These findings indicate that unconscious young adults who present without a traumatic incident with a low or normal blood pressure and without signs of focal pathology most probably suffer from a metabolic disorder, wherefore computed tomography of the brain may be postponed and often avoided.

Takotsubo cardiomyopathy associated with hypoglycemia: inverted takotsubo contractile pattern.
Classic takotsubo cardiomyopathy (TCM) is characterized by transient dysfunction of the apical portion of the left ventricle with hyperkinesis of the other parts of the heart wall. Recently, wall motion abnormalities in parts other than in the apical portion of the heart have been reported. Inverted TCM is one form of these anomalies. ⋯ Thus, undiagnosed self-limited TCM/SC cases are possible among hypoglycemic patients. TCM/SC is reported to be a cause of torsade de pointes, which can be fatal. This might warrant an echocardiogram for hypoglycemic patients so as not to overlook TCM/SC in the emergency department.

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.

A 69-year-old man presented to the emergency department with hematemesis, hypotension, tachycardia, and hypothermia. The emergency physician performed a bedside ultrasound of the chest, heart, and abdomen. The heart was unable to be visualized in the parasternal, apical, or subxiphoid windows, and free fluid and particulate matter were visualized in the chest and abdomen. ⋯ The presence of air in the pericardial sac results in nonvisualization of the heart on ultrasound. Fluid in the chest and abdomen may be visualized in the posterior upper abdominal windows. Although these ultrasound findings alone are not entirely specific for esophageal perforation, when coupled with a high index of suspicion due to the patient presentation, ultrasound can be one of the most portable, readily available, low-cost, and minimally invasive techniques to make the diagnosis of esophageal perforation.

In minor cases, contrast extravasation may cause pain, swelling, and localized erythema. However, in more severe cases, extensive tissue and skin necrosis, ulceration, and compartment syndrome may occur, often necessitating a surgical consultation. Hyaluronidase has been used successfully in the management of extravasated contrast media in several reports. ⋯ In a follow-up 4 hours later, marked improvement was observed. Sixteen hours after hyaluronidase treatment, the tissue had reverted to a near-normal state with no pain, erythema, swelling, or tenderness noted. Hyaluronidase successfully treated this extravasation of a large volume of iodinated contrast and appears to be a reasonable treatment option for more extensive subcutaneous contrast media extravasations.
