RESUMEN
Injury patterns of the hand and wrist can be complex and challenging for the emergency physician to diagnose and treat. The ability of the hand to perform delicate maneuvers requires a very intricate interplay of bones, ligaments, and tendons. Unfortunately, due to the omnipresence of the hand, the hand and wrist are commonly injured. These injuries can be debilitating if not treated correctly and can be both time-consuming and fraught with medicolegal risk. This article provides the necessary knowledge to diagnose and treat common hand and wrist injuries encountered in the emergency department.

Emergency neurology is a complex and rapidly changing field. Its evolution can be attributed in part to increased imaging options, debates about optimal treatment, and simply the growth of emergency medicine as a specialty. Every year, a number of articles published in emergency medicine or other specialty journals should become familiar to the emergency physician. This review summarizes neurology articles published in 2016, which the authors consider crucial to the practice of emergency medicine. The articles are categorized according to disease process, with the understanding that there can be significant overlap among articles.

The emergent evaluation and treatment of generalized convulsive status epilepticus presents challenges for emergency physicians. This disease is one of the few in which minutes can mean the difference between life and significant morbidity and mortality. It is imperative to use parallel processing and have multiple treatment options planned in advance, in case the current treatment is not successful. There is also benefit to exploring, or initiating, treatment algorithms to standardize the care for these critically ill patients.

Aneurysmal subarachnoid hemorrhage (SAH) is a neurological emergency with high risk of neurological decline and death. Although the presentation of a thunderclap headache or the worst headache of a patient's life easily triggers the evaluation for SAH, subtle presentations are still missed. The gold standard for diagnostic evaluation of SAH remains noncontrast head computed tomography (CT) followed by lumbar puncture if the CT is negative for SAH. Management of patients with SAH follows standard resuscitation of critically ill patients with the emphasis on reducing risks of rebleeding and avoiding secondary brain injuries.

BACKGROUND: Influenza is an acute respiratory virus that results in significant worldwide morbidity and mortality each year. As emergency physicians, we are often the first to encounter patients with seasonal influenza. It is therefore critical that we draw on the most recent and relevant research when we make clinical decisions regarding the diagnosis, treatment, and prophylaxis of this disease. METHODS: A MEDLINE literature search from August 2009 to August 2015 was performed using the keywords influenza vaccination efficacy AND systematic, influenza AND rapid antigen testing, and Oseltamivir AND systematic, while limiting the search to human studies written in the English language. General review articles and case reports were omitted. Each of the selected articles then underwent a structured review. RESULTS: We identified 163 articles through our literature search, of which 68 were found to be relevant to our clinical questions. These studies then underwent a rigorous review from which recommendations were given. CONCLUSIONS: Influenza vaccine efficacy continues to range between 40% and 80%. Vaccination has the potential to decrease disease severity and is recommended for individuals older than 6 months of age. If resources permit, vaccination can be offered to patients presenting to the emergency department. Rapid antigen detection for influenza is a simple bedside test with high specificity, but generally low sensitivity. If a patient presents with a syndrome consistent with influenza and has negative rapid antigen detection, they should either receive a confirmatory reverse transcriptase polymerase chain reaction or be treated as if they have influenza. Treatment with neuraminidase inhibitors can decrease the duration of influenza and is recommended in hospitalized patients, or in those with high risk of complications.

The emergent management of a traumatic injury can be an extremely intense situation. These assessments can be even more difficult when patients have an underlying psychiatric condition. After a protocoled evaluation of the traumatic injuries, the psychological manifestation of diseases can be addressed. The appropriate use of physical or chemical restraints to facilitate the work-up is paramount in the ability of the provider to protect patients and staff from agitated and traumatized patients. The emergency medicine provider should have a low threshold for including psychiatry in the treatment plans, as the long-term sequelae of these entities require specialized treatment.

INTRODUCTION: There is scant literature regarding the optimal resident physician staffing model of academic emergency departments (ED) that maximizes learning opportunities. A department of emergency medicine at a large inner-city academic hospital initiated a team-based staffing model. Its pre-interventional staffing model consisted of residents and attending physicians being separately assigned patients, resulting in residents working with two different faculty providers in the same shift. This study aimed to determine if the post-interventional team-based system, in which residents were paired with a single attending on each shift, would result in improved residents' learning and clinical experiences as manifested by resident evaluations and the number of patients seen. METHODS: This retrospective before-and-after study at an academic ED with an annual volume of 52,000 patients examined the mean differences in five-point Likert-scale evaluations completed by residents assessing their ED rotation experiences in both the original and team-based staffing models. The residents were queried on their perceptions of feeling part of the team, decision-making autonomy, clinical experience, amount of supervision, quality of teaching, and overall rotational experience. We also analyzed the number of patients seen per hour by residents. Paired sample t-tests were performed. Residents who were in the program in the year preceding and proceeding the intervention were eligible for inclusion. RESULTS: 34 of 38 eligible residents were included (4 excluded for lack of evaluations in either the pre- or post-intervention period). There was a statistically significant improvement in resident perception of the quality and amount of teaching, 4.03 to 4.27 (mean difference=0.24, p=0.03). There were non-statistically significant trends toward improved mean scores for all other queries. Residents also saw more patients following the initiation of the team-based model, 1.24 to 1.56 patients per hour (mean difference=0.32, p=0.0005). CONCLUSION: Adopting a team-based physician staffing model is associated with improved resident perceptions of quality and amount of teaching. Residents also experience a greater number of patient evaluations in a team-based model.

Although the altered mental status is a common presentation in the emergency department, altered mental status caused by endocrine emergencies is rare. The altered patient could have an endocrine cause that can quickly improve with appropriate diagnosis and interventions. When dealing with limited information and an obtunded patient, it is important to have a broad differential diagnosis, pick up on the physical examination findings, and evaluate laboratory abnormalities that could suggest an underlying endocrine emergency. This article outlines the findings and provides a description of altered patients with endocrine emergencies to facilitate the diagnosis and treatment in the emergency department.

INTRODUCTION: Procedural sedation and analgesia is a core competency in emergency medicine. Propofol is replacing midazolam in many emergency departments. Barriers to performing procedural sedation include resource utilization. We hypothesized that emergency nursing time is shorter with propofol than midazolam, without increasing complications. METHODS: Retrospective analysis of a procedural sedation registry for two community emergency departments with combined census of 100,000 patients/year. Demographics, procedure, and ASA physical classification status of adult patients receiving procedural sedation between 2007-2010 with midazolam or propofol were analyzed. Primary outcome was dedicated emergency nursing time. Secondary outcomes were procedural success, ED length of stay, and complication rate. Comparative statistics were performed with Mann-Whitney, Kruskal-Wallis, chi-square, or Fisher's exact test. Linear regression was performed with log-transformed procedural sedation time to define predictors. RESULTS: Of 328 procedural sedation and analgesia, 316 met inclusion criteria, of which 60 received midazolam and 256 propofol. Sex distribution varied between groups (midazolam 3% male; propofol 55% male; P = 0.04). Age, procedure, and ASA status were not significantly different. Propofol had shorter procedural sedation time (propofol 32.5 ± 24.2 minutes; midazolam 78.7 ± 51.5 minutes; P < 0.001) and higher rates of procedural success (propofol 98%; midazolam 92%; P = 0.02). There were no significant differences between complication rates (propofol 14%; midazolam 13%; P = 0.88) or emergency department length of stay (propofol 262.5 ± 132.8 minutes; midazolam 288.6 ± 130.6 minutes; P = 0.09). DISCUSSION: Use of propofol resulted in shorter emergency nursing time and higher procedural success rate than midazolam with a comparable safety profile.

The anatomy of the hand is complex, which allows for the dexterity, strength, and adaptability of the most functional aspect of the musculoskeletal system. The evaluation and management of injuries to this area can be time consuming and pose a significant medicolegal risk to the emergency physician. Improperly diagnosed and managed injuries can lead to chronic pain, inability to perform activities of daily living, and even seemingly minor injuries can lead to missed work causing a significant cost to the individual and society. The purpose of this article is to review injuries to the hand and wrist and discuss diagnostic studies and treatment plans that the emergency physician can use to treat patients effectively and minimize their exposure to risk.

OBJECTIVE: Calcium channel blocker (CCB) toxicity, in particular that induced by verapamil and diltiazem, presents clinical challenges with no true antidote. Levosimendan, a calcium sensitizer, improves cardiac contractility in patients with heart failure. We tested the hypothesis that calcium channel sensitization will prolong survival in a rat model of severe verapamil poisoning. METHODS: This was a blinded, randomized, controlled animal study. Wistar rats (mean weight, 371 +/- 50 g) were used. Verapamil (2.5 mg/ml) was infused at a rate of 37.5 mg/kg per hour. Bolus doses of levosimendan (5 microg/mL) were given at 0 min (12 microg/kg) and 5 min (18 microg/kg); saline control was of equal volume. The rats were intubated and maintained under general anesthesia with isoflurane. Electrocardiographic activity and core temperature were monitored during the poisoning and treatment phases. Each rat underwent femoral vein cannulation and was then randomized, in blinded fashion, to receive either levosimendan or an equal volume of saline at 0 and 5 minutes. Death, defined as 1 minute of asystole, was used as the primary endpoint. RESULTS: Rats treated with levosimendan died before the control group (7.37 +/- 0.7 min [n=7] vs. 16.4 +/- 4.2 [n=7] [ p=.053]). All animals experienced bradycardia prior to asystole. DISCUSSION: Although levosimendan has the ability to sensitize and enhance binding of troponin C to Ca2+, this study did not show an improvement in survival time in the setting of verapamil toxicity. This may be attributed to levosimendan's inhibition of phosphodiesterase, which possibly exacerbated the CCB-induced hypotension. CONCLUSION: In this rat model, levosimendan as a solitary antidotal treatment for verapamil toxicity was not beneficial.
