Shoulder Pseudodislocation Associated with Calcific Tendinitis/Bursitis and Diagnosed by Point of Care Ultrasound.

BACKGROUND: Shoulder pseudodislocation, or "drooping shoulder," presents with acute pain and deformity of the joint, with radiographs demonstrating inferior subluxation of the humeral head relative to the glenoid fossa. The diagnosis must be made promptly and distinguished from true glenohumeral dislocation, both to avoid unnecessary attempts at closed reduction and to facilitate investigation of the underlying cause, which may include septic arthritis, hemarthrosis, or other emergent etiologies. Point-of-care ultrasound (POCUS) may be useful in the evaluation of emergency department (ED) patients with suspected pseudodislocation. CASE REPORT: A 50-year old female presented to the ED with an acutely painful and deformed shoulder but atypical history and physical examination. Initial radiography appeared to show a glenohumeral dislocation, but POCUS, done to guide intra-articular lidocaine injection, led to recognition of pseudodislocation and subsequent diagnosis of calcific tendinitis/bursitis, a condition not previously associated with inferior humeral subluxation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Shoulder pseudodislocation must be considered in the evaluation of patients with suspected glenohumeral dislocation, but atypical features on history, physical examination, or initial plain radiography. POCUS may facilitate prompt diagnosis and identification of the underlying etiology.

Use of Tandem Perimortem Cesarean Section and Open-Chest Cardiac Massage in the Resuscitation of Peripartum Cardiomyopathy Cardiac Arrest.

Cardiac arrest and resuscitation of the pregnant woman at gestational term is rare. Depending on the circumstances of cardiac arrest and its timing, options are limited for allowing successful resuscitation of both mother and neonate. Herein, we describe the use of tandem perimortem cesarean section and thoracotomy for open-chest cardiac massage in a young woman with newly diagnosed peripartum cardiomyopathy. We used goal-directed resuscitation including diagnostic ultrasonography and capnography to assist in decision making and successfully resuscitated both mother and neonate to hospital discharge without discernable long-term complications.

Cardiopulmonary ultrasound for critically ill adults improves diagnostic accuracy in a resource-limited setting: the AFRICA trial.

OBJECTIVE: To assess the effects of a cardiopulmonary ultrasound (CPUS) examination on diagnostic accuracy for critically ill patients in a resource-limited setting. METHODS: Approximately half of the emergency medicine resident physicians at the Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, were trained in a CPUS protocol. Adult patients triaged to the resuscitation area of the emergency department (ED) were enrolled if they exhibited signs or symptoms of shock or respiratory distress. Patients were assigned to the intervention group if their treating physician had completed the CPUS training. The physician's initial diagnostic impression was recorded immediately after the history and physical examination in the control group, and after an added CPUS examination in the intervention group. This was compared to a standardised final diagnosis derived from post hoc chart review of the patient's care at 24 h by two blinded, independent reviewers using a clearly defined and systematic process. Secondary outcomes were 24-h mortality and use of IV fluids, diuretics, vasopressors and bronchodilators. RESULTS: Of 890 patients presenting during the study period, 502 were assessed for eligibility, and 180 patients were enrolled. Diagnostic accuracy was higher for patients who received the CPUS examination (71.9% vs. 57.1%, Δ 14.8% [CI 0.5%, 28.4%]). This effect was particularly pronounced for patients with a 'cardiac' diagnosis, such as cardiogenic shock, congestive heart failure or acute valvular disease (94.7% vs. 40.0%, Δ 54.7% [CI 8.9%, 86.4%]). Secondary outcomes were not different between groups. CONCLUSIONS: In an urban ED in Ghana, a CPUS examination improved the accuracy of the treating physician's initial diagnostic impression. There were no differences in 24-h mortality and a number of patient care interventions.

Understanding ethical dilemmas in the emergency department: views from medical students' essays.

BACKGROUND: For medical students, the emergency department (ED) often presents ethical problems not encountered in other settings. In many medical schools there is little ethics training during the clinical years. The benefits of reflective essay writing in ethics and professionalism education are well established. OBJECTIVES: The purpose of this study was to determine and categorize the types of ethical dilemmas and scenarios encountered by medical students in the ED through reflective essays. METHODS: During a 4(th)-year emergency medicine rotation, all medical students wrote brief essays on an ethical situation encountered in the ED, and participated in an hour debriefing session about these essays. Qualitative analysis was performed to determine common themes from the essays. The frequency of themes was calculated. RESULTS: The research team coded 173 essays. The most common ethical themes were autonomy (41%), social justice (32.4%), nonmaleficence (31.8%), beneficence (26.6%), fidelity (12%), and respect (8.7%). Many of the essays contained multiple ethical principles that were often in conflict with each other. In one essay, a student grappled with the decision to intubate a patient despite a preexisting do-not-resuscitate order. This patient encounter was coded with autonomy, beneficence, and nonmaleficence. Common scenarios included ethical concerns when caring for critical patients, treatment of pain, homeless or alcoholic patients, access to care, resource utilization, and appropriateness of care. CONCLUSION: Medical students encounter patients with numerous ethically based issues. Frequently, they note conflicts between ethical principles. Such essays constitute an important resource for faculty, resident, and student ethics training.

Current State of Point-of-Care Ultrasound Use Within Family Medicine.

BACKGROUND AND OBJECTIVES: Following the publication of Point-of-Care-Ultrasound (POCUS) curriculum guidelines from the American Academy of Family Physicians in 2016, there has been a rapid expansion in POCUS curricula across family medicine departments in the US. There is growing appreciation for the potential role of POCUS in enhancing the clinical care family physicians provide to patients. The primary aim of our study was to evaluate the utilization of POCUS in outpatient clinic care across Family Medicine departments nationwide and to identify perceived or realized barriers in integrating POCUS use for clinic care. METHODS: The questions were part of a larger omnibus survey of US Department of Family Medicine chairs, conducted by the Council of Academic Family Medicine Educational Research Alliance (CERA) between August 6 to August 31, 2021. RESULTS: 81% of departments have at least 1 POCUS-trained faculty, with 44% of departments using POCUS in some ambulatory clinical care. Currently, only 6% have established billing for the POCUS they perform. Faculty time, as well as funding, for POCUS training were seen as 2 primary barriers. The purchasing of equipment and billing for POCUS were described by FMCs as difficult. CONCLUSIONS: As POCUS use continues to rise in Family Medicine, it is imperative to create a more efficient and less hindered road to growth. Collaboration across departments to share best practices in training, purchasing equipment and billing for POCUS will be important to facilitate high-quality POCUS access for our patients.

Continuous Inferior Vena Cava Diameter Tracking through an Iterative Kanade-Lucas-Tomasi-Based Algorithm.

Ultrasound assessment of the respiratory-induced change in size of the inferior vena cava is a useful technique in the evaluation and management of critically ill patients. We have developed an automated technique based on the Kanade-Lucas-Tomasi feature tracker and pyramidal segmentation to continuously track the diameter of the inferior vena cava during ultrasound. To test the accuracy of this automated process, the inferior vena cava of 47 spontaneously breathing patients were measured by trained ultrasound physicians and compared against the results obtained via the automated tracking. Good agreement between the techniques was found, with intra-class correlation coefficients for maximum vessel diameter, minimum diameter and caval index of 0.897, 0.967 and 0.975, respectively. More than 95% of the difference between physicians and automated measurements agreed to within 10% of the inferior vena cava collapse. Furthermore a phenomenon of cardiac collapsibility index variability was observed and reported. The accuracy and precision of this algorithmic technique provide a foundation for future automated measures for critical care ultrasound.

"Concordance" Revisited: A Multispecialty Appraisal of "Concordant" Preliminary Abdominopelvic CT Reports.

PURPOSE: To determine whether resident abdominopelvic CT reports considered prospectively concordant with the final interpretation are also considered concordant by other blinded specialists and abdominal radiologists. METHODS: In this institutional review board-approved retrospective cohort study, 119 randomly selected urgent abdominopelvic CT examinations with a resident preliminary report deemed prospectively "concordant" by the signing faculty were identified. Nine blinded specialists from Emergency Medicine, Internal Medicine, and Abdominal Radiology reviewed the preliminary and final reports and scored the preliminary report with respect to urgent findings as follows: 1.) concordant; 2.) discordant with minor differences; 3.) discordant with major differences that do not alter patient management; or 4.) discordant with major differences that do alter patient management. Predicted management resulting from scores of 4 was recorded. Consensus was defined as majority agreement within a specialty. Consensus major discrepancy rates (ie, scores 3 or 4) were compared to the original major discrepancy rate of 0% (0/119) using the McNemar test. RESULTS: Consensus scores of 4 were assigned in 18% (21/119, P < .001, Emergency Medicine), 5% (6/119, P = .03, Internal Medicine), and 13% (16/119, P < .001, Abdominal Radiology) of examinations. Consensus scores of 3 or 4 were assigned in 31% (37/119, P < .001, Emergency Medicine), 14% (17/119, P < .001, Internal Medicine), and 18% (22/119, P < .001, Abdominal Radiology). Predicted management alterations included hospital status (0-4%), medical therapy (1%-4%), imaging (1%-10%), subspecialty consultation (3%-13%), nonsurgical procedure (3%), operation (1%-3%), and other (0-3%). CONCLUSIONS: The historical low major discrepancy rate for urgent findings between resident and faculty radiologists is likely underreported.
