A Perfect Storm: Tyrosine Kinase Inhibitor-Associated Polymorphic Ventricular Tachycardia.
Oral tyrosine kinase inhibitors (TKIs) are becoming increasingly common in oncology practice due to ease of administration and patient preference. This class of medications is relatively unknown to emergency physicians. ⋯ Here we present a case of electrical storm (ES) thought to be associated with ibrutinib, a TKI. The ES was unabated despite antidysrhythmic therapy and electrical cardioversion, and was treated with supportive care, which eventually included the use of extracorporeal membrane oxygenation. This patient had no risk factors or apparent causes of recurrent ventricular tachycardia. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: ES has not previously been described with ibrutinib, but may be associated with off-target effects of the drug.

Case Reports
Assessment of Volume Status and Appropriate Fluid Replenishment in the Setting of Nephrotic Syndrome.
When the permeability of the glomerular filtration barrier increases, leading to proteinuria, nephrotic syndrome (NS) occurs. First episodes or relapses of NS can be concurrent with acute gastroenteritis (AGE) infections. This condition can cause further deterioration of the hypovolemic state, as intravascular water is lost through both AGE-related vomiting/diarrhea and NS-related fluid shifting into the interstitium. In this case report, we wish to raise the issues about the difficult management of children presenting with both NS and AGE. ⋯ We report two cases characterized by concurrence of NS and AGE. Despite our intervention, case #1 required dialysis, whereas in the case #2 we restored the patient's liquid homeostasis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: No guidelines helping general physicians in the management of children presenting with both NS and AGE are available in the literature. However, it is common for these patients to seek the first line of treatment at emergency departments. In these patients, restoring the liquid homeostasis is a challenge, but some key points can help the physicians with first-line management: 1) carefully evaluate the signs of hypovolemia (edematous state can be misleading); 2) bear in mind that-in hypovolemic, severely hypoalbuminemic (serum albumin levels < 2 g/dL) NS children-initial fluid administration should be followed by a 20% albumin infusion if oligoanuria persists; intravenous 4.5% albumin may be a valid alternative as a first-line therapy instead of crystalloid and 20% albumin; and 3) pay attention when using furosemide; it should only be administered after albumin infusion or after hypovolemia correction.

Colchicine poisoning is an uncommon but serious form of drug intoxication. It may produce life-threatening systemic effects. In toxic doses it produces nausea and vomiting and bone marrow suppression, often leading to sepsis, hypocalcemia, adult respiratory distress syndrome, and direct cardiotoxic effects. ⋯ Among drug intoxications, colchicines can lead to severe clinical conditions. All patients suspected of having colchicine intoxication should be managed in the pediatric intensive care unit regardless of the actual degree of poisoning.

Hemorrhagic Pericardial Cyst Diagnosis Accelerated by Emergency Physician Echocardiography: A Case Report.
The differential diagnosis for chest pain in the emergency department is broad and includes both benign and life-threatening conditions-with pericardial cyst as a rare example. Emergency physician-performed point-of-care focused cardiac ultrasound (FOCUS) is increasingly recognized as a useful modality in the evaluation of patients with chest pain. ⋯ We report a case of hemorrhagic pericardial cyst in a young woman presenting with chest pain in which findings on FOCUS contradicted findings on chest x-ray study and thus, accelerated diagnosis and definitive treatment. We also comment on epidemiology, pathophysiology, clinical presentation, diagnosis, and management of this uncommon, potentially fatal cause of chest pain. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report aims to bring an uncommon case to the attention of emergency providers and emphasize the importance of facility with FOCUS. Although definitive diagnosis and management were not accomplished at the bedside in this case, an abnormal finding on FOCUS prompted further investigation and timely treatment.

Various complications are reported with Clostridium difficile infection (CDI), including fulminant CDI. Fulminant CDI is an underappreciated life-threatening condition associated with complications such as toxic megacolon and bowel perforation. ⋯ A 79-year-old woman presented to the Emergency Department with altered mental status. She was admitted and conservatively treated for a left thalamic hemorrhage. While hospitalized, she developed watery diarrhea due to Clostridium difficile. Although metronidazole was initiated, she developed altered mental status and septic shock. Abdominal x-ray study and computed tomography revealed a significantly dilatated colon and a massive pneumoperitoneum. She underwent subtotal colectomy with a 14-day course of intravenous meropenem. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case suggests that we must be aware of the complications that CDI may present and adequately consider surgical management because early diagnosis and surgical treatment is critical to reduce the mortality of fulminant CDI.
