Case Reports
Successful Glenohumeral Shoulder Reduction With Combined Suprascapular and Axillary Nerve Block.
Anterior glenohumeral dislocation is a common injury seen in the emergency department (ED) that sometimes requires procedural sedation for manual reduction. When compared with procedural sedation for dislocation reductions, peripheral nerve blocks provide similar patient satisfaction scores but have shorter ED length of stays. In this case report, we describe the first addition of an ultrasound-guided axillary nerve block to a suprascapular nerve block for reduction of an anterior shoulder dislocation in the ED. ⋯ A 34-year-old man presented to the ED with an acute left shoulder dislocation. The patient was a fit rock climber with developed muscular build and tone. An attempt to reduce the shoulder with peripheral analgesia was unsuccessful. A combined suprascapular and axillary nerve block was performed with 0.5% bupivacaine, allowing appropriate relaxation of the patient's musculature while providing excellent pain control. The shoulder was then successfully reduced without procedural sedation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Procedural sedation for reduction of anterior shoulder dislocations is time consuming, resource intensive, and can be risky in some populations. The addition of an axillary nerve block to a suprascapular nerve block allows for more complete muscle relaxation to successfully reduce a shoulder dislocation without procedural sedation.

Artifactual hypoglycemia is a low glucose measurement in a normoglycemic patient. Patients in a shock state or with extremity hypoperfusion can metabolize a higher proportion of the glucose in the poorly perfused tissue, and blood obtained from those tissues may have far lower glucose concentration than the blood in the central circulation. ⋯ We present the case of a 70-year-old woman with systemic sclerosis, progressive functional decline, and cool digital extremities. The initial point-of-care testing (POCT) for glucose was 55 mg/dL from her index finger, with subsequent repeated low POCT glucose reading, despite glycemic repletion and contradictory euglycemic serologic readings from her peripheral i.v. sites. Two separate POCTs were then obtained from her finger and her antecubital fossa, which had vastly different glucose readings; the latter was in congruence with her i.v. draws. The patient was diagnosed with artifactual hypoglycemia. Alternative sources of blood to avoid artifactual hypoglycemia on POCT samples are discussed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Artifactual hypoglycemia is a rare but commonly misdiagnosed phenomenon that can occur in emergency department patients when peripheral perfusion is limited. We encourage physicians to confirm peripheral capillary results with a venous POCT or explore alternative sources of blood to avoid artificial hypoglycemia. Small absolute errors can matter when the erroneous result is hypoglycemia.

Rhino-Orbital Cerebral Mucormycosis in a Diabetic Patient: An Emergency Medicine Case Report.
Rhino-orbital cerebral mucormycosis (ROCM) is a rare infection caused by an invasive fungus and found predominantly in immunocompromised patients. The presentation of ROCM ranges from a mild headache, fever, and sinusitis to vision loss, altered mental status, and facial disfigurement secondary to local tissue invasion. ROCM can cause significant morbidity and mortality and requires prompt diagnosis with timely evaluation by surgical and infectious disease specialists. Cases of ROCM have been reported extensively in internal medicine, infectious disease, and otolaryngology literature. However, there are very few reports in emergency medicine literature in the United States. ⋯ A 72-year-old woman presented to the Emergency Department (ED) with altered mental status, 4 days of left-sided facial numbness and weakness, and sudden facial pain, swelling, and erythema. Laboratory analysis was consistent with diabetic ketoacidosis. Noncontrast computed tomography of the head and magnetic resonance imaging of the brain demonstrated findings indicative of invasive fungal infection of the left sinus and orbit with extension to the cavernous sinus and surrounding cranial nerves. She was initiated on broad-spectrum antifungals, but based on the extent of the infection, was not a surgical candidate. She subsequently transitioned to a comfort-based plan of care and died 6 days after initial ED presentation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Early recognition and initiation of treatment can potentially mitigate the devastating outcomes of ROCM, therefore it is critical to be aware of this condition and have a high level of suspicion in susceptible patients.

POINT-OF-CARE ULTRASOUND FOR GUIDANCE OF CLOSED REDUCTION OF FIFTH METACARPAL NECK (BOXER'S) FRACTURE.
Ultrasound has been used previously in fracture identification, analgesia delivery, and fracture reduction for patients in the emergency department. It has not been previously described as a tool for the guidance of closed fracture reduction in fifth metacarpal neck fractures ("boxer's fractures"). ⋯ A 28-year-old man presented with hand pain and swelling after punching a wall. Point-of-care ultrasound revealed a significantly angulated fifth metacarpal fracture, which was confirmed with a subsequent hand x-ray study. After an ultrasound-guided ulnar nerve block, closed reduction was performed. Ultrasound was used to assess reduction and ensure improvement in bony angulation during the closed reduction attempts. Post-reduction x-ray study confirmed improved angulation and adequate alignment. Why Should an Emergency Physician Be Aware of This? Point-of-care ultrasound has previously had efficacy in fracture diagnosis and anesthesia delivery for fifth metacarpal fractures. Ultrasound can also be used at the bedside to assist in the determination of adequate fracture reduction when performing closed reduction of a boxer's fracture.

Balloon tamponade of esophagogastric variceal hemorrhage is a lifesaving but challenging procedure. One difficulty that often arises is coiling of the tube in the oropharynx. We describe a novel use of the bougie as an external stylet to help guide placement of the balloon to help overcome this challenge. ⋯ The bougie may be considered as an adjunct for placement of tamponade balloons for massive esophagogastric variceal hemorrhage when placement proves refractory to traditional techniques. We think this can be a valuable tool in the emergency physician's procedural repertoire.
