RESUMO
BACKGROUND: Autoamputation of the appendix is a condition associated with the Ladd's procedure, a pediatric surgical technique for correction of intestinal malrotation. A 4-year-old male patient with a history of a Ladd's procedure performed as a newborn was brought in by his mother for "passing intestine" just prior to arrival. She reported that for several weeks her son had intermittent, crampy abdominal pain that resolved after the unusual-appearing bowel movement. After reviewing an image of the bowel movement, and in consultation with pediatric surgery, it was concluded that the patient had passed a devascularized appendix in his stool immediately prior to arrival. CASE REPORT: A 4-year-old boy with a past medical history of heterotaxy syndrome (inversion of the thoraco-abdominal organs), a double outlet right ventricle, and Ladd's procedure presented to the Emergency Department (ED) after "passing intestine" in his stool. Close examination of the photo demonstrated a tubular structure with taenia, consistent with an appendix. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Autoamputation of the appendix is an uncommon presentation in the ED. Passing a devascularized appendix is a benign condition and can present with weeks of intermittent abdominal pain that resolves with passage of appendix in the stool. Remnants of the appendix can remain within the intestinal lumen years after the Ladd's procedure. Emergency physicians with a general awareness of this rare phenomenon can confidently make the diagnosis and reassure worried parents.

OBJECTIVE: Social media has been gaining traction among learners and educators for its ability to stimulate discussion, increase participation, and promote knowledge sharing. Despite the growing research around the benefits of social media in education, there is little evidence on how it is being incorporated into emergency ultrasound (EUS) fellowships. This study aims to determine the preference and use of social media by engaging with program directors across EUS programs in the United States to assess the current landscape of and attitudes toward social media use. METHODS: This was a cross-sectional study. An online questionnaire was electronically sent to all EUS fellowship directors across the country. The survey consisted of questions regarding current practice patterns, policies, and perceptions regarding the use of social media in EUS fellowship programs. RESULTS: Ninety-six ultrasound fellowship programs were identified for inclusion into this study. A total of 64 participants completed the survey, representing a 63% response rate. Thirty-eight percent (95% confidence interval [CI] = 26% - 50%) of responding fellowship programs have an official social media outlet and 25% have a separate ultrasound handle for their EM residency program. Fifty-eight percent (95% CI = 46% - 70%) of programs do not provide training to fellows and residents on the social media outlets used by their program. The top two social media outlets currently being used by programs are Twitter and YouTube to disseminate educational content and knowledge sharing. Twenty-eight percent (95% CI = 17% - 39%) of programs create or post new ultrasound content at least once per month. Regarding barriers in the use of social media in EUS fellowships, 57% (95% CI = 45% - 69%) of program directors sited lack of time as the primary reason for decreased usage and implementation. Eighty-four percent (95% CI = 75% - 93%) of responders felt that social media has the potential to impact patient care. CONCLUSIONS: The results of this study indicate that there is perceived value in utilizing social media resources in EUS education; however, certain challenges need to be further evaluated.
RESUMO
BACKGROUND: CPR training at mass gathering events is an important part of health initiatives to improve cardiac arrest survival. However, it is unclear whether training lay bystanders using an ultra-brief video at a mass gathering event improves CPR quality and responsiveness. OBJECTIVE: To determine if showing a chest-compression only (CCO) Ultra-Brief Video (UBV) at a mass gathering event is effective in teaching lay bystanders CCO-CPR. METHODS: Prospective control trial in adults (age >18) who attended either a women's University of Arizona or a men's Phoenix Suns basketball game. Participants were evaluated using a standardized cardiac arrest scenario with Laerdal Skillreporter™ mannequins. CPR responsiveness (calling 911, time to calling 911, starting compressions within two minutes) and quality (compression rate, depth, hands-off time) were assessed for participants and data collected at Baseline and Post-intervention. Different participants were tested before and after the exposure of the UBV. Data were analyzed via the intention to treat principle using logistic regression for binary outcomes and median regression for continuous outcomes, controlling for clustering by venue. RESULTS: A total of 96 people were consented (Baseline=45; Post intervention=51). CPR responsiveness post intervention improved with faster time to calling 911 (s) and time to starting compressions (sec). Likewise, CPR quality improved with deeper compressions and improved hands-off time. CONCLUSIONS: Showing a UBV at a mass gathering sporting event is associated with improved CPR responsiveness and performance for lay bystanders. This data provides further support for the use of mass media interventions.

BACKGROUND: External ultrasound transducer disinfection is common practice in medicine. Unfortunately, clinically significant organisms, such as methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, and Klebsiella pneumonia spread throughout healthcare facilities via direct contact despite disinfection protocols. Ultrasound transducers and coupling gel provide potential vectors for pathogen transmission, especially in immunocompromised and high-risk patient populations. Our objective was to conduct a survey to investigate the variety of cleaning solutions or sanitary wipes used and evaluate current standard practice for transducer disinfection across emergency medicine training programs in the United States. FINDINGS: Eighty-three academic emergency medicine programs participated in this study. Eighty-seven percent (95 % CI 80-94 %) of responding programs do not have a mandated protocol or standard contact time for transducer disinfection. Ninety percent (95 % CI 84-96 %) of institutions use disinfectant solution or disinfectant wipes, as the standard of practice, to cleanse ultrasound transducers after every use. CONCLUSIONS: Currently, there is a great deal of variability with regard to non-endocavitary transducer disinfection protocols that seems to stem from the vast number of disinfectant products and ultrasound manufacturer disparate recommendations. In order to mitigate risk to patients and reduce health care costs linked to nosocomial infections; healthcare providers, ultrasound companies, and disinfectant manufacturers must develop a universal use disinfectant and a standard protocol for ultrasound device disinfection for noncritical device disinfection in the emergency department.
RESUMO
Demand for bedside ultrasound in medicine has created a need for earlier exposure to ultrasound education during the clinical years of undergraduate medical education. Although bedside ultrasound is often used for invasive medical procedures, there is no standardized educational model for procedural skills that can provide the learner a real-life simulated experience. The objective of our study was to describe a unique fresh cadaver preparation model, and to determine the impact of a procedure-focused ultrasound training session. This study was a cross-sectional study at an urban academic medical center. A sixteen-item questionnaire was administered at the beginning and end of the session. Fifty-five third year medical students participated in this 1-day event during their surgical clerkship. Students were trained to perform the following ultrasound-guided procedures: internal jugular vein cannulation, femoral vein cannulation femoral artery cannulation and pericardiocentesis. Preparation of the fresh cadaver is easily replicated and requires minor manipulation of cadaver vessels and pericardial space. Fifty-five medical students in their third year participated in this study. All of the medical students agreed that US could help increase their confidence in performing procedures in the future. Eighty percent (95 % CI 70-91 %) of students felt that there was a benefit of learning ultrasound-based anatomy in addition to traditional methods. Student confidence was self-rated on a five-point Likert scale. Student confidence increased with statistical significance in all of the skills taught. The most dramatic increase was noted in central venous line placement, which improved from 1.95 (SD = 0.11) to 4.2 (SD = 0.09) (p < 0.001). The use of fresh cadavers for procedure-focused US education is a realistic method that improves the confidence of third year medical students in performing complex but critical procedures.

BACKGROUND: CPR training in schools is a public health initiative to improve out of hospital cardiac arrest (OHCA) survival. It is unclear whether brief video training in students improves CPR quality and responsiveness and skills retention. OBJECTIVES: Determine if a brief video is as effective as classroom instruction for chest compression-only (CCO) CPR training in high school students. METHODS: This was a prospective cluster-randomized controlled trial with three study arms: control (sham video), brief video (BV), and CCO-CPR class. Students were randomized and clustered based on their classrooms and evaluated using a standardized OHCA scenario measuring CPR quality (compression rate, depth, hands-off time) and responsiveness (calling 911, time to calling 911, starting compressions within 2min). Data was collected at baseline, post-intervention and 2 months. Generalized linear mixed models were used to analyze outcome data, accounting for repeated measures for each individual and clustering by class. RESULTS: 179 students (14-18 years) were consented in 7 classrooms (clusters). At post-intervention and 2 months, BV and CCO class students called 911 more frequently and sooner, started chest compressions earlier, and had improved chest compression rates and hands-off time compared to baseline. Chest compression depth improved significantly from baseline in the CCO class, but not in the BV group post-intervention and at 2 months. CONCLUSIONS: Brief CPR video training resulted in improved CPR quality and responsiveness in high school students. Compression depth only improved with traditional class training. This suggests brief educational interventions are beneficial to improve CPR responsiveness but psychomotor training is important for CPR quality.
