The case of late presentation of a pseudoaneurysm and an arteriovenous fistula (AVF) of the common femoral artery and vein secondary to penetrating trauma is reported. Traumatic AVF and pseudoaneurysm may be present within a variety of clinical conditions, which sometimes makes it difficult to detect them clinically. Undiagnosed AVF can lead to clinical manifestations mostly secondary to increased output generated by the fistula. ⋯ The mechanism of the injury, wound location and tract, and physical findings after a penetrating thigh trauma can help to predict femoral artery injury. Also, occult injuries to the medial thigh after penetrating trauma may be easily overlooked on the physical examination. Furthermore, bedside ultrasound performed by an emergency physician may be helpful in diagnosing occult vascular injuries.

Case Reports
Case Report: An electrocardiogram of Spontaneous Pneumothorax Mimicking Arm Lead Reversal.
There are several previously documented findings for electrocardiograms (ECGs) of spontaneous pneumothorax. These findings include axis deviation, T-wave inversion, and right bundle branch block. When an ECG has the arm leads incorrectly placed, the ECG will display right axis deviation and inversion of the P waves in lead I. There have been no previously published ECGs of spontaneous pneumothorax that have shown the same findings as reversal of the limb leads of an ECG. ⋯ If a patient presents with chest pain and shortness of breath, and the patient's ECG is flagged for limb lead reversal despite being set up correctly, the physician should raise clinical suspicion for a possible spontaneous pneumothorax.

In caring for patients in the Emergency Department (ED), the emergency physician (EP) will often utilize consulting specialists and pharmacists. In the event of an untoward patient outcome, disagreement may arise regarding the liability of each provider. ⋯ Consulting physicians may establish a relationship through an overt or implied agreement to participate in a patient's care, or by reviewing specific tests and studies for the purpose of diagnosis and treatment. The courts have defined the duty of the pharmacist to safely dispense medication, and have ascribed the duty to warn of medication side effects to the prescribing physician.
