Abstract
INTRODUCTION Acute aortic occlusion (AAO) is a rare but serious condition associated with significant morbidity and mortality. OBJECTIVE This review provides an emergency medicine focused evaluation of AAO, including presentation, assessment, and emergency department (ED) management based on current evidence. DISCUSSION AAO refers to obstruction of blood flow through the aorta due to either thrombosis or embolism. This condition primarily affects older adults ages 60-70 with cardiovascular comorbidities and most commonly presents with signs and symptoms of acute limb ischemia, though the gastrointestinal tract, kidneys, and spinal cord may be affected. The first line imaging modality includes computed tomography angiography of the chest, abdomen, and pelvis. ED resuscitative management consists of avoiding extremes of blood pressure or heart rate, maintaining normal oxygen saturation and euvolemic status, anticoagulation with heparin, and pain control. Emergent consultation with the vascular surgery specialist is recommended to establish a plan for restoration of perfusion to ischemic tissues via endovascular or open techniques. High rates of baseline comorbidities present in the affected population as well as ischemic and reperfusion injuries place AAO patients at high risk for complications in an immediate and delayed fashion after surgical management. CONCLUSIONS An understanding of AAO can assist emergency clinicians in diagnosing and managing this rare but devastating disease.

Abstract
INTRODUCTION Airway compromise is the second leading cause of potentially preventable death on the battlefield. Prehospital airway management is often unavoidable in a kinetic combat environment and expected to increase in future wars where timely evacuation will be unreliable and air superiority not guaranteed. We compared characteristics of survivors to non-survivors among combat casualties undergoing prehospital airway intubation. MATERIALS AND METHODS We requested all Department of Defense Trauma Registry (DODTR) encounters during 2007-2023 with documentation of any airway intervention or assessment within the first 72-h after injury. We conducted a retrospective cohort study of all casualties with intubation documented in the prehospital setting. We used descriptive and inferential statistical analysis to compare survivors through 7 days post injury versus non-survivors. We constructed 3 multivariable logistic regression models to test for associations between interventions and 7-day survival after adjusting for injury severity score, mechanism of injury, and receipt of sedatives, paralytics, and blood products. RESULTS There were 1377 of 48,301 patients with documentation of prehospital intubation in a combat setting. Of these, 1028 (75%) survived through 7 days post injury. Higher proportions of survivors received ketamine, paralytic agents, parenteral opioids, and parenteral benzodiazepines; there was no difference in the proportions of survivors versus non-survivors receiving etomidate. The multivariable models consistently demonstrated positive associations between 7-day survival and receipt of non-depolarizing paralytics and opioid analgesics. CONCLUSIONS We found an association between non-depolarizing paralytic and opioid receipt with 7-day survival among patients undergoing prehospital intubation. The literature would benefit from future multi-center randomized controlled trials to establish optimal pharmacologic strategies for trauma patients undergoing prehospital intubation.

Abstract
INTRODUCTION Acute mastoiditis is a serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of mastoiditis, including the presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Acute mastoiditis most commonly affects pediatric patients and is a suppurative infection of the mastoid air cells. It is often associated with otitis media, and common bacteria include Streptococcus and Staphylococcus. History and examination may reveal tympanic membrane erythema, pinna protrusion, postauricular erythema, mastoid tenderness with palpation, external canal swelling, otorrhea, fever, and malaise. The disease should be suspected in those who fail treatment for otitis media and those who demonstrate the aforementioned abnormalities on examination and systemic symptoms. Laboratory analysis may reveal evidence of systemic inflammation, but a normal white blood cell count and other inflammatory markers should not be used to exclude the diagnosis. Computed tomography (CT) of the temporal bones with intravenous contrast is the recommended imaging modality if the clinician is unsure of the diagnosis. CT may also demonstrate complications. Treatment includes antibiotics such as ampicillin-sulbactam or ceftriaxone as well as otolaryngology consultation. Complications may include subperiosteal and intracranial abscess, deep neck abscess, facial nerve palsy, meningitis/encephalitis, venous sinus thrombosis, and seizures. CONCLUSIONS An understanding of acute mastoiditis can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
BACKGROUND High-risk pulmonary embolism (PE) is a complex, life-threatening condition, and emergency clinicians must be ready to resuscitate and rapidly pursue primary reperfusion therapy. The first-line reperfusion therapy for patients with high-risk PE is systemic thrombolytics (ST). Despite consensus guidelines, only a fraction of eligible patients receive ST for high-risk PE. OBJECTIVE This review provides emergency clinicians with a comprehensive overview of the current evidence regarding the management of high-risk PE with an emphasis on ST and other reperfusion therapies to address the gap between practice and guideline recommendations. DISCUSSION High-risk PE is defined as PE that causes hemodynamic instability. The high mortality rate and dynamic pathophysiology of high-risk PE make it challenging to manage. Initial stabilization of the decompensating patient includes vasopressor administration and supplemental oxygen or high-flow nasal cannula. Primary reperfusion therapy should be pursued for those with high-risk PE, and consensus guidelines recommend the use of ST for high-risk PE based on studies demonstrating benefit. Other options for reperfusion include surgical embolectomy and catheter directed interventions. CONCLUSIONS Emergency clinicians must possess an understanding of high-risk PE including the clinical assessment, pathophysiology, management of hemodynamic instability and respiratory failure, and primary reperfusion therapies.

Abstract
INTRODUCTION Stevens Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are serious conditions that carry a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of SJS/TEN, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION SJS/TEN is a rare, delayed hypersensitivity reaction resulting in de-epithelialization of the skin and mucous membranes. The majority of cases are associated with medication or infection. Clinicians should consider SJS/TEN in any patient presenting with a blistering mucocutaneous eruption. Evaluation of the skin, mucosal, pulmonary, renal, genital, and ocular systems are essential in the diagnosis of SJS/TEN, as well as in the identification of complications (e.g., sepsis). Laboratory and radiological testing cannot confirm the diagnosis in the ED setting, but they may assist in the identification of complications. ED management includes stabilization of airway and breathing, fluid resuscitation, and treatment of any superimposed infections with broad-spectrum antibiotic therapy. All patients with suspected SJS/TEN should be transferred and admitted to a center with burn surgery, critical care, dermatology, and broad specialist availability. CONCLUSIONS An understanding of SJS/TEN can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
BACKGROUND Transvenous pacemaker placement is an integral component of therapy for severe dysrhythmias and a core skill in emergency medicine. OBJECTIVE This narrative review provides a focused evaluation of transvenous pacemaker placement in the emergency department setting. DISCUSSION Temporary cardiac pacing can be a life-saving procedure. Indications for pacemaker placement include hemodynamic instability with symptomatic bradycardia secondary to atrioventricular block and sinus node dysfunction; overdrive pacing in unstable tachydysrhythmias, such as torsades de pointes; and failure of transcutaneous pacing. Optimal placement sites include the right internal jugular vein and left subclavian vein. Insertion first includes placement of a central venous catheter. The pacing wire with balloon is then advanced until electromechanical capture is obtained with the pacer in the right ventricle. Ultrasound can be used to guide and confirm lead placement using the subxiphoid or modified subxiphoid approach. The QRS segment will demonstrate ST segment elevation once the pacing wire tip contacts the endocardial wall. If mechanical capture is not achieved with initial placement of the transvenous pacer, the clinician must consider several potential issues and use an approach to evaluating the equipment and correcting any malfunction. Although life-saving in the appropriate patient, complications may occur from central venous access, right heart catheterization, and the pacing wire. CONCLUSIONS An understanding of transvenous pacemaker placement is essential for emergency clinicians.

INTRODUCTION Myocarditis is a serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of myocarditis, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Myocarditis is an inflammatory syndrome of myocardium, most often resulting from a viral infection, that can cause life-threatening cardiovascular collapse. It has a highly variable presentation and no widely available specific diagnostic test, making it a challenging diagnosis. Emergency clinicians should obtain an electrocardiogram and perform bedside ultrasound to assess cardiac function. Treatment in the ED is largely supportive, focusing on resuscitation, cardiovascular support, cardiology specialist consultation, and appropriate disposition. CONCLUSIONS An understanding of myocarditis can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
INTRODUCTION Glucagon-like peptide 1 (GLP-1) based therapies, including GLP-1 agonists, are currently in use for treatment of diabetes and obesity. However, several complications may occur with their use. OBJECTIVE This narrative review provides a focused evaluation of GLP-1 agonist therapy and associated complications for emergency clinicians. DISCUSSION GLP-1 agonists potentiate insulin release and reduce gastric emptying and food intake. These agents have demonstrated significant improvements in glucose control in diabetics and weight loss in obese patients. The two most common agents include subcutaneous semaglutide (Ozempic, approved for type 2 diabetes, and Wegovy, approved for weight loss) and liraglutide (Saxenda, approved for weight loss, and Victoza, approved for type 2 diabetes), though an oral formulation of semaglutide is available (Rybelsus). While these drugs are associated with improved long-term outcomes, there are a variety of associated adverse events. The most common include gastrointestinal (GI) adverse events such as nausea, vomiting, diarrhea, and abdominal pain. Pancreatitis and biliary disease may also occur. Hypersensitivity including injection site reactions have been associated with use, with reports of anaphylaxis and other rashes. Renal adverse events are most commonly associated with severe GI losses. Hypoglycemia may occur when these agents are used with sulfonylureas or insulin. There is also an increased risk of diabetic retinopathy. Due to the current shortage and expense of these medications, many patients have attempted to obtain these medications from non-licensed and unregulated agents, which may be associated with increased risk of serious complications. CONCLUSIONS An understanding of the indications for GLP-1 agonist use and associated adverse events can assist emergency clinicians.

Abstract
BACKGROUND Multiple sclerosis (MS) is a rare but serious condition associated with significant morbidity. OBJECTIVE This review provides a focused assessment of MS for emergency clinicians, including the presentation, evaluation, and emergency department (ED) management based on current evidence. DISCUSSION MS is an autoimmune disorder targeting the central nervous system (CNS), characterized by clinical relapses and radiological lesions disseminated in time and location. Patients with MS most commonly present with long tract signs (e.g., myelopathy, asymmetric spastic paraplegia, urinary dysfunction, Lhermitte's sign), optic neuritis, or brainstem syndromes (bilateral internuclear ophthalmoplegia). Cortical syndromes or multifocal presentations are less common. Radiologically isolated syndrome and clinically isolated syndrome (CIS) may or may not progress to chronic forms of MS, including relapsing remitting MS, primary progressive MS, and secondary progressive MS. The foundation of outpatient management involves disease-modifying therapy, which is typically initiated with the first signs of disease onset. Management of CIS and acute flares of MS in the ED includes corticosteroid therapy, ideally after diagnostic testing with imaging and lumbar puncture for cerebrospinal fluid analysis. Emergency clinicians should evaluate whether patients with MS are presenting with new-onset debilitating neurological symptoms to avoid unnecessary testing and admissions, but failure to appropriately diagnose CIS or MS flare is associated with increased morbidity. CONCLUSIONS An understanding of MS can assist emergency clinicians in better diagnosing and managing this neurologically devastating disease.

Abstract
INTRODUCTION Malaria is a potentially fatal parasitic disease transmitted by the Anopheles mosquito. A resurgence in locally acquired infections has been reported in the U.S. OBJECTIVE This narrative review provides a focused overview of malaria for the emergency clinician, including the epidemiology, presentation, diagnosis, and management of the disease. DISCUSSION Malaria is caused by Plasmodium and is transmitted by the Anopheles mosquito. Disease severity can range from mild to severe. Malaria should be considered in any returning traveler from an endemic region, as well as those with unexplained cyclical, paroxysms of symptoms or unexplained fever. Patients most commonly present with fever and rigors but may also experience cough, myalgias, abdominal pain, fatigue, vomiting, and diarrhea. Hepatomegaly, splenomegaly, pallor, and jaundice are findings associated with malaria. Although less common, severe malaria is precipitated by microvascular obstruction with complications of anemia, acidosis, hypoglycemia, multiorgan failure, and cerebral malaria. Peripheral blood smears remain the gold standard for diagnosis, but rapid diagnostic tests are available. Treatment includes specialist consultation and antimalarial drugs tailored depending on chloroquine resistance, geographic region of travel, and patient comorbidities. Supportive care may be required, and patients with severe malaria will require resuscitation. Most patients will require admission for treatment and further monitoring. CONCLUSION Emergency medicine clinicians should be aware of the presentation, diagnosis, evaluation, and management of malaria to ensure optimal outcomes.

Abstract
Acute ischemic cerebrovascular accident (CVA) is a time-sensitive emergent diagnosis, requiring rapid diagnosis and consideration of thrombolytic administration. However, a myriad of cerebrovascular mimics creates a diagnostic challenge. A rare CVA mimic is Creutzfeldt-Jakob disease (CJD), a rapidly progressive fatal dementia due to protein misfolding. Magnetic resonance imaging (MRI) and neurology consultation for electroencephalogram (EEG) and specialized cerebrospinal fluid (CSF) studies are diagnostic while the patient is alive. All forms are fatal within months, and diagnosis can be confirmed on postmortem brain testing. While incredibly uncommon, emergency clinicians should consider this diagnosis in the proper patient to advocate for specialized CSF testing and potential palliative care consultation.

Abstract
INTRODUCTION Flexor tenosynovitis (FTS) is a deep space infection of an upper extremity digit which carries a high rate of morbidity. OBJECTIVE This review highlights the pearls and pitfalls of FTS, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION FTS typically occurs after direct penetrating trauma to the volar aspect of an upper extremity digit. Development of a deep space infection that quickly propagates through the flexor tendon sheath of a digit can result in serious structural damage to the hand and place the patient at risk for significant morbidity such as finger amputation or even result in death. Signs of FTS include symmetrical swelling of the affected finger, the affected finger being held in a flexed position, pain on any attempt of passive finger extension, and tenderness along the course of flexor tendon sheath, known as the Kanavel signs. Systemic symptoms such as fevers and chills may occur. Recognition of these signs and symptoms is paramount in diagnosis of FTS, as laboratory and imaging assessment is not typically diagnostic. ED management involves intravenous antibiotics and emergent surgical specialist consultation. CONCLUSION An understanding of the presentation and risk factors for development of FTS can assist emergency clinicians in diagnosing and managing this disease in an expedited fashion.

Abstract
INTRODUCTION Spontaneous cervical artery dissection (sCAD) is a serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of sCAD, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION sCAD is a condition affecting the carotid or vertebral arteries and occurs as a result of injury and compromise to the arterial wall layers. The dissection most commonly affects the extracranial vessels but may extend intracranially, resulting in subarachnoid hemorrhage. Patients typically present with symptoms due to compression of local structures, and the presentation depends on the vessel affected. The most common symptom is headache and/or neck pain. Signs and symptoms of ischemia may occur, including transient ischemic attack and stroke. There are a variety of risk factors for sCAD, including underlying connective tissue or vascular disorders, and there may be an inciting event involving minimal trauma to the head or neck. Diagnosis includes imaging, most commonly computed tomography angiography of the head and neck. Ultrasound can diagnose sCAD but should not be used to exclude the condition. Treatment includes specialist consultation (neurology and vascular specialist), consideration of thrombolysis in appropriate patients, symptomatic management, and administration of antithrombotic medications. CONCLUSIONS An understanding of sCAD can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
BACKGROUND Orthopedic injuries are commonly managed in the emergency department (ED) setting. Fractures and dislocations may require reduction for proper management. There are a variety of analgesic and sedative strategies to provide patient comfort during reduction. OBJECTIVE This narrative review evaluates hematoma block, intra-articular injection, intravenous regional analgesia (IVRA) (also known as the Bier block), and periosteal block for orthopedic analgesia in the ED setting. DISCUSSION Analgesia is an essential component of management of orthopedic injuries, particularly when reduction is necessary. Options in the ED setting include hematoma blocks, intra-articular injections, IVRA, and periosteal blocks, which provide adequate analgesia without procedural sedation or opioid administration. When used in isolation, these analgesic techniques decrease complications from sedation and the need for other medications, such as opioids, while decreasing ED length of stay. Emergency clinicians can also use these techniques as analgesic adjuncts. However, training in these techniques is recommended prior to routine use, particularly with IVRA. CONCLUSIONS Knowledge of analgesic techniques for orthopedic procedures can assist clinicians in optimizing patient care.

Abstract
INTRODUCTION Acute diverticulitis is a condition commonly seen in the emergency department (ED). Therefore, it is important for emergency medicine clinicians to be aware of the current evidence regarding the diagnosis and management of this disease. OBJECTIVE This paper evaluates key evidence-based updates concerning acute diverticulitis for the emergency clinician. DISCUSSION Diverticulitis is a complication of diverticulosis and most commonly affects the sigmoid and descending colon in Western countries. History and examination can suggest the diagnosis, with abdominal pain and tenderness in the left lower quadrant being the most common symptom and sign, respectively. Change in bowel habits and fever may also occur. Laboratory testing may demonstrate leukocytosis or an elevated C-reactive protein. Imaging options can include computed tomography (CT) of the abdomen and pelvis with intravenous contrast, magnetic resonance imaging (MRI), or ultrasound (US), though most classification systems for diverticulitis incorporate CT findings. While the majority of diverticulitis cases are uncomplicated, complications may affect up to 25% of patients. Treatment of complicated diverticulitis requires antibiotics and surgical consultation. Antibiotics are not required in select patients with uncomplicated diverticulitis. Appropriate patients for supportive care without antibiotics should be well-appearing, have pain adequately controlled, be able to tolerate oral intake, be able to follow up, have no complications, and have no immunocompromise or severe comorbidities. CONCLUSIONS An understanding of literature updates can improve the ED care of patients with acute diverticulitis.

Abstract
INTRODUCTION Guillain-Barré syndrome (GBS) is a rare but serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of GBS, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION GBS is a rare immune-mediated neurologic disorder with peripheral nerve injury. It most commonly presents weeks after a bacterial or viral infection, though there are a variety of associated inciting events. The diagnosis is challenging and often subtle, as only 25-30% of patients are diagnosed on their initial healthcare visit. Clinicians should consider GBS in patients with progressive ascending weakness involving the lower extremities associated with hyporeflexia, but the cranial nerves, respiratory system, and autonomic system may be involved. While the ED diagnosis should be based on clinical assessment, further evaluation includes laboratory testing, cerebrospinal fluid (CSF) analysis, and potentially neuroimaging. Not all patients demonstrate albumino-cytological dissociation on CSF testing. Several criteria exist to assist with diagnosis, including the National Institute of Neurological Disorders and Stroke criteria and the Brighton criteria. Management focuses first on assessment of the patient's hemodynamic and respiratory status, which may require emergent intervention. Significant fluctuations in heart rate and blood pressure may occur, and respiratory muscle weakness may result in the need for airway protection. Neurology consultation is recommended, and definitive treatment includes PLEX or IVIG. CONCLUSIONS An understanding of GBS can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
INTRODUCTION Infected urolithiasis is a serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of infected urolithiasis, including presentation, diagnosis, and management in the emergency department based on current evidence. DISCUSSION Although urolithiasis is common and the vast majority can be treated conservatively, the presence of a concomitant urinary tract infection significantly increases the risk of morbidity, to include sepsis and mortality. Identification of infected urolithiasis can be challenging as patients may have symptoms similar to uncomplicated urolithiasis and/or pyelonephritis. However, clinicians should consider infected urolithiasis in toxic-appearing patients with fever, chills, dysuria, and costovertebral angle tenderness, especially in those with a history of recurrent urinary tract infections. Positive urine leukocyte esterase, nitrites, and pyuria in conjunction with an elevated white blood cell count may be helpful to identify infected urolithiasis. Patients should be resuscitated with fluids and broad-spectrum antibiotics. Additionally, computed tomography and early urology consultation are recommended to facilitate definitive care. CONCLUSIONS An understanding of infected urolithiasis can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
INTRODUCTION Atrial fibrillation (AF) may lead to stroke, heart failure, and death. When AF occurs in the context of a rapid ventricular rate/response (RVR), this can lead to complications, including hypoperfusion and cardiac ischemia. Emergency physicians play a key role in the diagnosis and management of this dysrhythmia. OBJECTIVE This paper evaluates key evidence-based updates concerning AF with RVR for the emergency clinician. DISCUSSION Differentiating primary and secondary AF with RVR and evaluating hemodynamic stability are vital components of ED assessment and management. Troponin can assist in determining the risk of adverse outcomes, but universal troponin testing is not required in patients at low risk of acute coronary syndrome or coronary artery disease - especially patients with recurrent episodes of paroxysmal AF that are similar to their prior events. Emergent cardioversion is indicated in hemodynamically unstable patients. Rate or rhythm control should be pursued in hemodynamically stable patients. Elective cardioversion is a safe option for select patients and may reduce AF symptoms and risk of AF recurrence. Rate control using beta blockers or calcium channel blockers should be pursued in those with AF with RVR who do not undergo cardioversion. Anticoagulation is an important component of management, and several tools (e.g., CHA2DS2-VASc) are available to assist with this decision. Direct oral anticoagulants are the first-line medication class for anticoagulation. Disposition can be challenging, and several risk assessment tools (e.g., RED-AF, AFFORD, and the AFTER (complex, modified, and pragmatic) scores) are available to assist with disposition decisions. CONCLUSION An understanding of the recent updates in the literature concerning AF with RVR can assist emergency clinicians in the care of these patients.

Abstract
INTRODUCTION Acute limb ischemia is a rare but serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of acute limb ischemia, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Acute limb ischemia is defined as a sudden decrease in limb perfusion resulting in cessation of blood flow and nutrient and oxygen delivery to the tissues. This leads to cellular injury and necrosis, ultimately resulting in limb loss and potentially systemic symptoms with significant morbidity and mortality. There are several etiologies including native arterial thrombosis, arterial thrombosis after an intervention, arterial embolus, and arterial injury. Patients with acute limb ischemia most commonly present with severe pain and sensory changes in the initial stages, with prolonged ischemia resulting in weakness, sensory loss, and color changes to the affected limb. The emergency clinician should consult the vascular specialist as soon as ischemia is suspected, as the diagnosis should be based on the history and examination. Computed tomography angiography is the first line imaging modality, as it provides valuable information concerning the vasculature and surrounding tissues. Doppler ultrasound of the distal pulses may also be obtained to evaluate for arterial and venous flow. Once identified, management includes intravenous unfractionated heparin and vascular specialist consultation for revascularization. CONCLUSIONS An understanding of acute limb ischemia can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
BACKGROUND Posterior circulation (PC) stroke in adults is a rare, frequently misdiagnosed, serious condition that carries a high rate of morbidity. OBJECTIVE OF THE REVIEW This review evaluates the presentation, diagnosis, and management of PC stroke in the emergency department (ED) based on current evidence. DISCUSSION PC stroke presents most commonly with dizziness or vertigo and must be distinguished from more benign diagnoses. Emergency clinicians should consider this condition in patients with dizziness, even in younger patients and those who do not have traditional stroke risk factors. Neurologic examination for focal neurologic deficit, dysmetria, dysarthria, ataxia, and truncal ataxia is essential, as is the differentiation of acute vestibular syndrome vs. spontaneous episodic vestibular syndrome vs. triggered episodic vestibular syndrome. The HINTS (head impulse, nystagmus, and test of skew) examination can be useful for identifying dizziness presentations concerning for stroke when performed by those with appropriate training. However, it should only be used in patients with continuous dizziness who have ongoing nystagmus. Contrast tomography (CT), CT angiography, and CT perfusion have limited sensitivity for identifying PC strokes, and although magnetic resonance imaging is the gold standard, it may miss some PC strokes early in their course. Thrombolysis is recommended in patients presenting within the appropriate time window for thrombolytic therapy, and although some data suggest endovascular therapy for basilar artery and posterior cerebral artery infarcts is beneficial, its applicability for all PC strokes remains to be determined. CONCLUSIONS An understanding of PC stroke can assist emergency clinicians in diagnosing and managing this disease.

Abstract
Hyperthyroidism is a diagnosis existing along a spectrum of severity. Patients present with a variety of signs and symptoms: tachycardia, elevated heart rate, anxiety, changes in mental status, gastrointestinal disturbances, and hyperthermia. Management of subclinical hyperthyroidism and thyrotoxicosis without thyroid storm is heavily dependent on outpatient evaluation. Thyroid storm is the most severe form of hyperthyroidism with the highest mortality. Management of thyroid storm follows a stepwise approach, with resuscitation and detection of the precipitating cause being paramount. Special attention should be paid to cardiac function in patients with thyroid storm before treatment, as these patients may develop cardiac collapse.

Abstract
Suicide pacts among elderly couples afflicted by a terminal disease process present a significant challenge to emergency clinicians. If one member of the pair aborts their attempt, the surviving member of a dual suicide attempt can present a complex case with numerous clinical issues reflected by Hickam's dictum rather than by Occam's razor. Thus, emergency clinicians must keenly search for a multitude of concomitant but compounding conditions, potentially projected onto pre-existing comorbidities in an elderly population. The authors present a case of a suicide pact in which one member of the couple completed the attempt while the surviving member experienced carbon monoxide toxicity, compartment syndrome, rhabdomyolysis, and renal failure following her aborted suicide attempt.

Abstract
Orbital cellulitis is a dangerous condition that has a variety of etiologies and risk factors such as chronic sinusitis. If left untreated, it may result in orbital compartment syndrome. A 19-year-old male presented with evidence of orbital cellulitis, increased intraocular pressures, and orbital compartment syndrome as a result of a retrobulbar abscess. He was started on ampicillin/sulbactam, the emergency clinician performed a lateral canthotomy and cantholysis, and the case was discussed with ophthalmology and otolaryngology on call. The patient was taken to the operating room for further surgical therapy. Cultures revealed Fusobacterium necrophorum and Aspergillus spp. Orbital cellulitis is an infection of the tissue posterior to the orbital septum. Common bacterial etiologies of orbital cellulitis include Staphylococcus spp, Streptococcus spp, and Haemophilus spp. Chronic sinusitis secondary to an Aspergillus infection increases the risk of superinfection given the inability to clear nasal secretions. Diagnosis of orbital cellulitis can be clinical, but imaging with computed tomography of the orbits with intravenous contrast can assist. Treatment includes broad-spectrum antibiotics and ophthalmology consultation. If left untreated, orbital cellulitis may lead to orbital compartment syndrome, requiring lateral canthotomy and cantholysis. Prompt identification of orbital compartment syndrome and surgical intervention with lateral canthotomy and cantholysis can help restore the function of the optic nerve if performed in a timely manner. Clinicians should consider broadening the antibiotic coverage to include carbapenems or adding on anaerobic coverage with metronidazole in patients with concern for abscess formation in the setting of chronic sinusitis.

Abstract
INTRODUCTION Airway management is a critical component of the management of emergency department (ED) patients. The ED airway literature primarily focuses upon endotracheal intubation; relatively less is known about the ED use of extraglottic devices (EGDs). The goal of this study was to describe the frequency of use, success, and complications for EGDs among ED patients. METHODS The National Emergency Airway Registry (NEAR) is a prospective, multi-center, observational registry. It captures data on all ED patients at participating sites requiring airway management. Intubating clinicians entered all data into an online system as soon as practical after each encounter. We conducted a secondary analysis of these data for all ED encounters in which EGD placement occurred. We used descriptive statistics to characterize these encounters. RESULTS Of 19,071 patients undergoing intubation attempts, 56 (0.3%) underwent EGD placement. Of 25 participating sites, 13 reported no cases undergoing EGD placement; the median number of EGDs placed per site was 2 (interquartile range 1-2.5, range 1-31). Twenty-nine (54%) patients had either hypotension or hypoxia prior to the start of airway management. Clinicians reported anticipation of a difficult airway in 55% and at least one difficult airway characteristic in 93% of these patients. Forty-one encounters entailed placement of a laryngeal mask airway (LMA®) Fastrach™, 33 of whom underwent subsequent successful intubation through the EGD and 7 of whom underwent intubation by alternative methods. An additional 10 encounters utilized a standard LMA® device. Providers placed 34 (61%) EGDs during the first intubation attempt. Seventeen EGD patients (30%) experienced peri-procedure adverse events, including 14 (25%) experiencing hypoxemia. None of these patients expired due to failed airways. CONCLUSIONS EGD use was rare in this multi-center ED registry. EGD occurred predominantly in patients with difficult airway characteristics with favorable airway management outcomes. Clinicians should consider this emergency airway device for patients with a suspected difficult airway.

Abstract
BACKGROUND Status epilepticus is associated with significant morbidity and mortality and is divided into convulsive status epilepticus and nonconvulsive status epilepticus (NCSE). OBJECTIVE This review provides a focused evaluation of NCSE for emergency clinicians. DISCUSSION NCSE is a form of status epilepticus presenting with prolonged seizure activity. This disease is underdiagnosed, as it presents with nonspecific signs and symptoms, most commonly change in mental status without overt convulsive motor activity. Causes include epilepsy, cerebral pathology or injury, any systemic insult such as infection, and drugs or toxins. Mortality is primarily related to the underlying condition. Patients most commonly present with altered mental status, but other signs and symptoms include abnormal ocular movements and automatisms such as lip smacking or subtle motor twitches in the face or extremities. The diagnosis is divided into electrographic and electroclinical, and although electroencephalogram (EEG) is recommended for definitive diagnosis, emergency clinicians should consider this disease in patients with prolonged postictal state after a seizure with no improvement in mental status, altered mental status with acute cerebral pathology (e.g., stroke, hypoxic brain injury), and unexplained altered mental status. Assessment includes laboratory evaluation and neuroimaging with EEG. Management includes treating life-threatening conditions, including compromise of the airway, hypoglycemia, hyponatremia, and hypo- or hyperthermia, followed by rapid cessation of the seizure activity with benzodiazepines and other antiseizure medications. CONCLUSIONS An understanding of the presentation and management of NCSE can assist emergency clinicians in the care of these patients.

Abstract
INTRODUCTION Metformin toxicity is a rare but serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of metformin toxicity, including diagnosis, initial resuscitation, and management in the emergency department (ED) based on current evidence. DISCUSSION Metformin is a common medication used for treatment of diabetes mellitus. Metformin toxicity is a spectrum of conditions that may be differentiated into three subgroups: metformin-associated lactic acidosis (MALA), metformin-induced lactic acidosis (MILA), and metformin-unrelated lactic acidosis (MULA). MILA is a condition found predominantly in patients chronically taking metformin or those with large acute overdoses. Conversely, MULA occurs in patients on metformin but with a critical illness stemming from a separate cause. MALA is rare but the most severe form, with mortality rates that reach 50%. Differentiating these entities is difficult in the ED setting without obtaining metformin levels. Patients with metformin toxicity present with nonspecific gastrointestinal symptoms and vital sign abnormalities. Laboratory analysis will reveal a high lactate with anion gap metabolic acidosis. Patients presenting with elevated lactate levels in the setting of metformin use should be considered at risk for the most severe form, MALA. Patients with MALA require aggressive treatment with intravenous fluids, treatment of any concomitant condition, and early consideration of hemodialysis, along with specialist consultation such as nephrology and toxicology. CONCLUSIONS An understanding of metformin toxicity can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
BACKGROUND Hyperglycemia is a common finding in patients presenting to the emergency department (ED). Recommendations addressing uncomplicated hyperglycemia in the ED are limited, and the management of those without a prior diagnosis of diabetes presents a challenge. OBJECTIVE This narrative review will discuss the ED evaluation and management of hyperglycemic adult patients without a history of diabetes who do not have evidence of a hyperglycemic crisis, such as diabetic ketoacidosis or hyperosmolar hyperglycemic state. DISCUSSION Many adults who present to the ED have risk factors for diabetes and meet American Diabetes Association (ADA) criteria for diabetes screening. A new diagnosis of type 2 diabetes can be established in the ED by the ADA criteria in patients with a random plasma glucose ≥ 200 mg/dL (11.1 mmol/L) and symptoms of hyperglycemia. The diagnosis should be considered in patients with an elevation in random blood glucose > 140 mg/dL (7.8 mmol/L). Treatment may begin in the ED and varies depending on the presenting severity of hyperglycemia. Treatment options include metformin, long-acting insulin, or deferring for close outpatient management. CONCLUSIONS Emergency clinician knowledge of the evaluation and management of new-onset hyperglycemia and diabetes is important to prevent long-term complications.

Abstract
INTRODUCTION Blast injury is a unique condition that carries a high rate of morbidity and mortality, often with mixed penetrating and blunt injuries. OBJECTIVE This review highlights the pearls and pitfalls of blast injuries, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Explosions may impact multiple organ systems through several mechanisms. Patients with suspected blast injury and multisystem trauma require a systematic evaluation and resuscitation, as well as investigation for injuries specific to blast injuries. Blast injuries most commonly affect air-filled organs but can also result in severe cardiac and brain injury. Understanding blast injury patterns and presentations is essential to avoid misdiagnosis and balance treatment of competing interests of patients with polytrauma. Management of blast victims can also be further complicated by burns, crush injury, resource limitation, and wound infection. Given the significant morbidity and mortality associated with blast injury, identification of various injury patterns and appropriate management are essential. CONCLUSIONS An understanding of blast injuries can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
Cardiac arrest is the loss of organized cardiac activity. Unfortunately, survival to hospital discharge is poor, despite recent scientific advances. The goals of cardiopulmonary resuscitation (CPR) are to restore circulation and identify and correct an underlying etiology. High-quality compressions remain the foundation of CPR, optimizing coronary and cerebral perfusion pressure. High-quality compressions must be performed at the appropriate rate and depth. Interruptions in compressions are detrimental to management. Mechanical compression devices are not associated with improved outcomes but can assist in several situations.
