RESUMO
Diagnosis and management of liver abscesses in low- and middle-income countries (LMICs) is difficult due to limited diagnostic imaging availability. Limited data is available describing the use of point-of-care ultrasound (POCUS) in the diagnosis and percutaneous aspiration of liver abscesses in resource-limited countries. We describe a 21-year-old female who was diagnosed with a liver abscess. The diagnosis of liver abscess was made via POCUS, and the patient was successfully managed with empiric antimicrobials and repeated POCUS-assisted percutaneous needle aspiration. In resource-limited settings, adequate training of personnel and availability of POCUS may help in early diagnosis and treatment of liver abscess - thus helping to reduce its related morbidity and mortality - while also aiding in resource conservation.
RESUMO
BACKGROUND: Aimed at bridging the gap in continuing medical education (CME) resource availability in low- and middle-income countries (LMICs), the "Continuing Medical Education on Stick" (CMES) program introduces two technological solutions: a universal serial bus (USB) drive and the CMES-Pi computer facilitating access to monthly updated CME content without data cost. Feedback from users suggests a lack of content on tropical infectious diseases (IDs) and content from a Western perspective, which may be less relevant in LMIC settings. METHODS: This quality improvement project was intended to identify areas for improvement of the CMES database to better meet the educational needs of users. We compared the CMES content with the American Board of Emergency Medicine (ABEM) Exam content outline to identify gaps. The curriculum map of the CMES library, encompassing content from 2019 to 2024, was reviewed. An anonymous survey was conducted among 47 global users to gather feedback on unmet educational needs and suggestions for content improvements. All healthcare workers who were members of the CMES WhatsApp group were eligible to participate in the survey. RESULTS: The curriculum map included 2,572 items categorized into 23 areas. The comparison with the ABEM outline identified gaps in several clinical areas, including procedures, traumatic disorders, and geriatrics, which were represented -5%, -5%, and -4% in the CMES library compared with the ABEM outline, respectively. Free responses from users highlighted a lack of content on practical skills, such as electrocardiogram (ECG) interpretation and management of tropical diseases. Respondents identified emergency medical services (EMS)/prehospital care (81%), diagnostic imaging (62%), and toxicology/pharmacology (40%) as the most beneficial areas for clinical practice. In response to feedback from users, new content was added to the CMES platform on the management of sickle cell disease and dermatologic conditions in darkly pigmented skin. Furthermore, a targeted podcast series called "ID for Users of the CMES Program (ID4U)" has been launched, focusing on tropical and locally relevant ID, with episodes now being integrated into the CMES platform. CONCLUSIONS: The project pinpointed critical gaps in emergency medicine (EM) content pertinent to LMICs and led to targeted enhancements in the CMES library. Ongoing updates will focus on including more prehospital medicine, diagnostic imaging, and toxicology content. Further engagement with users and education on utilizing the CMES platform will be implemented to maximize its educational impact. Future adaptations will consider local relevance over the ABEM curriculum to better serve the diverse needs of global users.
RESUMO
Background There are a relatively limited number of emergency medicine (EM) medical education (MedEd) fellowships with few trainees at each program, creating barriers to local collaboration and networking. While best practices for developing MedEd journal clubs exist, there has not been an established national EM MedEd journal club. To address this need, we created a national journal club, the Council of Residency Directors (CORD) MedEd Journal Club (MEJC), to facilitate collaboration and networking opportunities by providing a synchronous online journal club. Objectives Our primary objective was to create a network for collaboration across geographical barriers to form a virtual community of practice (CoP) around the shared domain of evidence-based MedEd. Our secondary objective was to improve MedEd fellows' knowledge, skills, and attitudes surrounding MedEd research. Tertiary objectives included (1) broadening fellow exposure to key topics within MedEd, (2) describing how to develop scholarly work within MedEd, and (3) filling a perceived need for building a national MedEd virtual CoP. Curricular design The concept and objectives of the CORD MEJC were introduced to fellows and fellowship directors through a national listserv in March of 2022. Fellows volunteered to lead virtual sessions via Zoom on a monthly basis. Session fellow leaders independently chose the topics and were asked to submit two to three journal club articles discussing the topic at least two weeks in advance of each session. No topics were repeated throughout the academic year. Impact/effectiveness Our quality improvement survey results indicated that the CORD MEJC is meeting its primary and secondary objectives. Survey results will be utilized as part of a continuous quality improvement initiative to enhance our program structure and curricula for the 2023-2024 academic year.
RESUMO
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.

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.

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.

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.

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.

Gamification is an effective teaching tool that improves engagement and knowledge retention. Tabletop role-playing games are dynamic games that use random chance and foster player/leader partnership. To date, there are no teaching tools that mimic dynamic or unpredictable patient presentations. This style of game may work well as a tool for medical education in a simulation-based modality. In this report, we document the rules, materials, and training required to reproduce a hybrid game created to combine facets of simulation and tabletop role-playing games (TRPGs) to create a dynamic medical education tool. After testing the game for flaws and fluidity of gameplay, we plan to collect data evaluating emergency medicine residents' enjoyability and knowledge retention. In this article, we describe a novel TRPG simulation hybrid game that we hypothesize will improve learner enjoyability/engagement and have similar educational benefits to standard medical education.
RESUMO
Audience: The target audience for this small group session is post-graduate year (PGY) 1-4 emergency medicine (EM) residents, pediatric EM (PEM) fellows, and medical students. Introduction: Pediatric emergency department visits have been declining since the start of the COVID-19 pandemic, leading to decreased exposure to pediatric emergency care for EM residents and other learners in the ED.1 This is a major problem, given that the Accreditation Council for Graduate Medical Education (ACGME) mandates that a minimum of 20% of patient encounters or five months of training time for EM residents must occur with pediatric patients, with at least 50% of that time spent in the ED setting.2,3 A minimum of 12 months must be spent in the pediatric ED for PEM fellows,2 and an average of 7.1 weeks of medical school are spent in pediatric clerkships.4 This decrease in pediatrics exposure in the post-pandemic environment can be addressed through simulation and gamification. We selected the gamification method of an escape room to create an engaging environment in which learners could interface with key pediatric emergency medicine clinical concepts via group learning. Educational Objectives: By the end of this small group exercise, learners will be able to:Demonstrate appropriate dosing of pediatric code and resuscitation medicationsRecognize normal pediatric vital signs by ageDemonstrate appropriate use of formulas to calculate pediatric equipment sizes and insertion depthsRecognize classic pediatric murmursAppropriately diagnose congenital cardiac conditionsRecognize abnormal pediatric electrocardiograms (ECGs)Identify life-threatening pediatric conditionsDemonstrate intraosseous line (IO) insertion on a pediatric modelDemonstrate appropriate use of the Neonatal Resuscitation Protocol (NRP®) algorithms. Educational Methods: An escape room - a form of gamification - was utilized to engage the learners in active learning. Gamification is an increasingly popular educational technique being utilized in graduate medical education and refers to the conversion of serious, non-trivial material into a fun activity fashioned like a game in order to enhance engagement in learning.5 This educational method seeks to enhance knowledge, attitudes, and skills via components of games - such as puzzles and prizes - outside of the context of a traditional game.6 Though high-quality research data on the effectiveness of gamification methods in graduate medical education is limited, studies have shown that gamification enhances learning, attitudes, and behaviors.5,7 One randomized, clinical-controlled trial investigating the use of gamification to enhance patient outcomes found that patients of primary care physicians randomized to the gamification group reached blood pressure targets faster than in the control group.8 Escape rooms as a modality for education have been suggested to improve active learning and enhance learner engagement in the learning process.9 In an escape room, learners are "locked" in an artificial environment (whether digitally or in person) and must utilize their group or individual knowledge to solve puzzles and escape from their "entrapment."9,10 Escape rooms utilized as part of EM residency didactic training have demonstrated learner enthusiasm,11,12 desire to repeat the activity again,13 preference for escape rooms over traditional learning methods,14,15 improved confidence in communication and leadership skills,11,15 and improvement scores from pre- to post-testing.16We developed an escape room in which learners were divided into teams and informed that they would need to "escape" from our resident lounge by successfully completing all nine stations. The first team to complete all nine stations would win a prize. Only after the last team completed the ninth station and debriefing was complete could all teams be "freed" from the escape room. Research Methods: Learners provided anonymous online survey feedback regarding the quality of the educational content and the efficacy of the delivery method. Results: A post-participation survey was disseminated to 55 residents, 32 of whom attended the PEM Escape Room, with a response rate of 9% (3/32 residents). One hundred percent of respondents felt that the activity content was applicable to their needs as an emergency physician. The session was rated as excellent by 33.3% of respondents, and 66.7% of respondents rated the session as above average. A second survey was disseminated seven months after the event to the 24 remaining residents who attended the event, with a response rate of 46% (11/24 residents); eight attendees had graduated at the time of this survey dissemination. Results of the second survey indicated that 100% (24/24 residents) felt that the activity content was applicable to their needs as an emergency physician, 73% (17/24 residents) rated the session as excellent, and 27% (7/24 residents) rated the session as above average. Discussion: Though we received limited survey responses (3/32 on the first survey and 11/24 on the second survey), respondents felt that the educational content met their learning needs and was of high quality. We had six faculty members present to facilitate the escape room while there were four groups of residents (eight per group). The ideal faculty to resident ratio would be one faculty member per group with three to six players, based on prior literature showing that teams of more than six players take longer to complete escape room tasks.17,18 We also recognized the importance of sending out the feedback survey link early because we believe the delay in our survey being emailed to the residents contributed to the low response rate (three trainees).One participant provided the following feedback: "I think the 'escape room' struck an excellent balance with regard to trying to address knowledge that was relevant but also obscure or difficult enough that group/collaborative effort was required. I enjoyed the process and low stakes atmosphere." This quote nicely summarizes our take-aways: That the PEM escape room incorporates key tenets of adult learning theory. Also known as andragogy, adult learning theory posits that adult learners are self-directed, have prior life experiences that shape their learning process, learn for practical reasons (ie, choose to learn in order to fulfill the demands of their social role), and are problem-oriented in their learning.19 Though andragogy does not technically apply only to adults (as many children are self-directed learners),20 having an understanding of the practical and experiential nature via which adults approach learning allows the adult educator to appropriately cater educational activities to meet the adult learner's needs.This escape room aligned with the core tenets of adult learning theory in several ways. Specifically, residents were given autonomy of participation in the escape room and thus had to take initiative to promote their own learning.21 Topics featured in the escape room stations were selected based on their clinical challenges and high-yield for board examinations and patient care, making their relevance immediately obvious to learners; this is a key feature of catering to adult learners.22 The escape room provided a comfortable and collegial environment in which residents felt comfortable learning, fostering an ideal setting for mature learners.21 Direct and immediate feedback are key components of adult learning theory, and faculty members were physically present to provide feedback at each escape room station.22 Finally, working in teams required the learners to engage in active learning rather than acting as passive recipients of cognitive information.21 Thus, the PEM escape room serves as an ideal framework to meet the needs of the adult learner. Topics: Pediatrics, emergency medicine, pediatric emergency medicine.
RESUMO
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.

INTRODUCTION: Orbital cellulitis is an uncommon but serious condition that carries with it a potential for significant morbidity. OBJECTIVE: This review highlights the pearls and pitfalls of orbital cellulitis, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: Orbital cellulitis refers to infection of the globe and surrounding soft tissues posterior to the orbital septum. Orbital cellulitis is typically caused by local spread from sinusitis but can also be caused by local trauma or dental infection. It is more common in pediatric patients compared to adults. Emergency clinicians should first assess for and manage other critical, sight-threatening complications such as orbital compartment syndrome (OCS). Following this assessment, a focused eye examination is necessary. Though orbital cellulitis is primarily a clinical diagnosis, computed tomography (CT) of the brain and orbits with and without contrast is critical for evaluation of complications such as abscess or intracranial extension. Magnetic resonance imaging (MRI) of the brain and orbits with and without contrast should be performed in cases of suspected orbital cellulitis in which CT is non-diagnostic. While point-of-care ultrasound (POCUS) may be useful in differentiating preseptal from orbital cellulitis, it cannot exclude intracranial extension of infection. Management includes early administration of broad-spectrum antibiotics and ophthalmology consultation. The use of steroids is controversial. In cases of intracranial extension of infection (e.g., cavernous sinus thrombosis, abscess, or meningitis), neurosurgery should be consulted. CONCLUSION: An understanding of orbital cellulitis can assist emergency clinicians in diagnosing and managing this sight-threatening infectious process.

INTRODUCTION: Open globe injury (OGI) is a rare but serious condition that carries with it a high rate of morbidity. OBJECTIVE: This review highlights the pearls and pitfalls of OGI, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: OGI refers to full-thickness injury to the layers of the eye. OGI can be caused by blunt or sharp trauma, and subtypes include penetration, perforation, intraocular foreign body (IOFB), globe rupture, or mixed types. OGI is more common in males and usually secondary to work-related injury, but in women it is most commonly associated with falls. Emergency clinicians should first assess for and manage other critical, life-threatening injuries. Following this assessment, a thorough eye examination is necessary. Computed tomography (CT) may suggest the disease, but it cannot definitively exclude the diagnosis. While point-of-care ultrasound (POCUS) is highly sensitive and specific for some findings in OGI, its use is controversial due to potential globe content extrusion. Management includes protecting the affected eye from further injury, preventing Valsalva maneuvers that could extrude ocular contents, updating tetanus vaccination status, administering broad-spectrum antibiotics, and ophthalmology consultation for surgical intervention to prevent the sequelae of blindness and endophthalmitis. CONCLUSION: An understanding of OGI can assist emergency clinicians in diagnosing and managing this sight-threatening traumatic process.

We describe the case of a 4-year-old female who presented with sepsis and disseminated intravascular coagulation (DIC), developed ongoing intravascular hemolysis with acute renal failure from suspected pigment-induced acute tubular necrosis necessitating continuous renal replacement therapy (CRRT) for five days followed by four episodes of intermittent hemodialysis (iHD), and was subsequently diagnosed with paroxysmal cold hemoglobinuria (PCH). She was successfully treated with plasma exchange and eculizumab, a humanized monoclonal antibody targeting complement protein C5, and demonstrated significant improvement of hemolysis and recovery of renal function.
RESUMO
BACKGROUND: Skin and soft tissue infections are common emergency department (ED) presentations. These infections cover a wide spectrum of disease, from simple cellulitis to necrotizing fasciitis. Despite the commonality, a subset of skin and soft tissue infections known as necrotizing soft tissue infections (NSTIs) can cause significant morbidity and mortality. OBJECTIVE: This review evaluates the current evidence regarding the presentation, evaluation, and management of NSTI from the ED perspective. DISCUSSION: NSTIs are commonly missed diagnoses. History and physical examination findings are inconsistent, and the risk factors for this high mortality disease are common amongst ED populations. Laboratory evaluation and the Laboratory Risk in Necrotizing Fasciitis (LRINEC) score is helpful but is insufficient to rule out the disease. Imaging modalities including ultrasound, computed tomography, and magnetic resonance imaging are highly sensitive and specific, but may delay definitive management. The gold standard for diagnosis includes surgical exploration. Surgical intervention and empiric broad-spectrum antibiotic coverage are the foundations of treatment. Adjuvant therapies including hyperbaric oxygen and intravenous immunoglobulin have not yet been proven to be beneficial or to improve outcome. CONCLUSION: NSTIs are associated with significant morbidity and mortality. Knowledge of the history, examination, evaluation, and management is vital for emergency clinicians.

Audience: This tutorial should be utilized for emergency medicine (EM) interns and junior residents. Introduction: Ophthalmology is characteristically a weak area in both medical school and resident education. Medical students are rarely given formal didactic education on the use of the slit lamp or a systematic approach to examining the eye. For EM residents, this leads to inefficient and uncomfortable encounters with patients with eye complaints. We sought to develop a comprehensive emergency ophthalmology tutorial utilizing asynchronous learning followed by a hands-on skill session that would address this need. Educational Objectives: By the end of this small group didactic, learners will be able to: 1) demonstrate ability to focus on the various components of the slit lamp exam 2) demonstrate understanding of a systematic approach to the eye exam 3) demonstrate appropriate use of the Diaton, iCare, and Tonopen tonometers. Educational Methods: This two-hour small group didactic combines hands-on learning sessions to learn the slit lamp exam and tonometry measurement, with a systematic review of the eye exam to help learners better organize their exams and understand the use of necessary tools. Research Methods: The emergency ophthalmology tutorial was initially designed as an education project in which we collected pre- and post-participation surveys regarding resident comfort with various components of the emergency eye exam. After the course residents received a post-course survey to complete. Given the positive feedback we received from our residents regarding the tutorial, we applied for Institutional Review Board (IRB) approval to publish our retrospective survey data. Our IRB waived the need for participant consent. Results: Twelve emergency medicine residents including 11 interns and one post-graduate year (PGY) 2 resident participated in the emergency ophthalmology tutorial as part of our intern boot camp in July of 2021. Twelve PGY-1 residents initially signed up for the course and filled out the pre-participation survey but one of them was not able to attend their scheduled class, so a PGY-2 resident requested to attend.Prior to the course, we used a Likert scale from 1-7, finding that 61.5% (8/13) of participants felt very uncomfortable with performing slit lamp exams, 84.6% (11/13) felt very uncomfortable with using the Diaton tonometer, 76.9% (10/13) felt very uncomfortable with using the iCare tonometer, and 69.3% (9/13) felt uncomfortable or very uncomfortable with using a systematic approach to examining the eye. After the course, 75% (9/12) of participants felt that the course exceeded expectations in ensuring their ability to perform the subcomponents of the slit lamp exam, 75% (9/12) and 83.3% (10/12) of participants felt that the course exceeded expectations in ensuring their ability to use the Diaton and iCare tonometers, respectively, and 91.7% (11/12) felt that the course exceeded expectations in ensuring their ability to perform a systematic eye exam. Discussion: Participation in a 2-hour emergency ophthalmology tutorial with assigned asynchronous pre-course work improved emergency medicine resident comfort with various components of the eye exam. Topics: Emergency ophthalmology, eye exam, slit lamp, tonometry.
RESUMO
OBJECTIVE: Peripheral arterial disease (PAD) is associated with comorbid atherosclerosis of the coronary and carotid arteries and is a significant risk factor for stroke. However, cognitive function in PAD patients before clinically evident stroke remains poorly characterized. Here we hypothesized that, on neuropsychological testing, PAD patients would perform more poorly than healthy control subjects, and persons with mild cardiovascular disease (essential hypertension), but better than stroke patients, thus reflecting a continuum of cognitive impairment associated with increased severity of vascular disease. METHOD: The cognitive performance of 38 PAD patients (mean ankle-brachial index=0.67, Fontaine Class II) was contrasted with that of 23 healthy normotensive controls, 20 essential hypertensives, and 26 anterior ischemic stroke patients on twelve neuropsychological tests. RESULTS: PAD patients performed significantly more poorly than hypertensives and normotensives, but better than stroke patients, on seven tests of nonverbal memory, concentration, executive function, perceptuo-motor speed, and manual dexterity. Hypertensives displayed poorer performance than normotensives on tests of nonverbal memory and manual dexterity. These findings were independent of age, education, and depression scores. Higher diastolic blood pressure and plasma glucose levels predicted poorer performance of select cognitive tests by PAD patients. Eight to 67% of PAD patients displayed impaired performance (< 5(th) percentile of normotensive controls) on the seven aforementioned cognitive tests. CONCLUSIONS: PAD patients exhibit diminished performance across a variety of domains of cognitive function. Findings also suggest a continuum of cognitive impairment associated with increasingly severe manifestations of cardiovascular disease, thus emphasizing the need for enhanced preventative measures to avert functional declines.
