Introduction: Tension pyopneumothorax is a rare, life-threatening condition that occurs as a complication of intrathoracic infection or bronchopleural fistula. In the few cases reported in the literature, the patients typically have multiple comorbidities, underlying lung disease, and/or an immunocompromised state.Case Report: This case describes tension pyopneumothorax in a previously healthy adolescent male with no existing risk factors for this disease. After emergent stabilization and admission, surgical exploration of the chest revealed no fistulas or pleural defects. Extensive workup did not show any underlying risk factors for development of this condition.Conclusion: This case of pyopneumothorax with progression to tension physiology is exceedingly rare. Uniquely, the patient had no underlying medical or anatomical predisposition to developing this condition. The case also emphasizes pediatric patients’ capacity to compensate in the setting of critical illness.

Introduction: The perforation of a cecal diverticulum is a rare and challenging condition for the emergency physician.Case Report: A 47-year-old man with a past surgical history of bilateral inguinal hernia repair presented to the emergency department (ED) with acute abdominal pain of three days’ duration. Pain was localized to the right lower quadrant (RLQ), with anorexia as the only associated symptom. Upon arrival to the ED, his exam demonstrated focal RLQ tenderness to palpation, rebound tenderness, and guarding. Labs did not show any elevation in inflammatory markers, liver enzymes, or lipase. Computed tomography showed no evidence of acute appendicitis, colitis, or hernia recurrence. After morphine and reassessment, the patient still had a focal peritoneal exam in the RLQ. Surgical consultation was obtained and recommended additional non-opioid analgesia as well as serial abdominal exams. After several repeat abdominal exams, there was no change in the focality of the patient’s pain. Surgery was reconsulted and opted to take the patient to the operating room for exploratory laparoscopy with “appendicitis” as the presumptive diagnosis. Pathology report revealed a perforated cecal diverticulum that was adherent to the abdominal wall. The patient did well and was discharged on his third postoperative day.Conclusion: This case further underlines that even in the era of sensitive imaging tools, the diagnostic value of a targeted physical exam with clinical re-evaluation can never be overestimated.

Dabigatran etexilate mesylate is a direct thrombin inhibitor used for reducing the risk of stroke andsystemic embolism in patients with non-valvular atrial fibrillation. Dabigatran belongs to a new generationof oral agents for anticoagulation – the direct oral anticoagulants (DOACs). The DOACs also includethe factor Xa inhibitors rivaroxaban, apixaban, and edoxaban. In the case of major or life-threateningbleeding and/or the need for emergent invasive procedures, a reversal agent is needed if a patient istaking one of these medications. Research has shown the efficacy of idarucizumab as an antidote inhealthy volunteers, but data in the case of life-threatening bleeds remains limited. We report a caseof a patient who suffered a traumatic subarachnoid hemorrhage and received effective treatment withidarucizumab. Along with other reports, our case demonstrates that dabigatran-related major and/orlife-threatening bleeds may be effectively counteracted by idarucizumab. This provides an option toemergency department providers in managing clinically significant bleeds in patients taking dabigatran.

Objectives: People experiencing homelessness (PEH) have significant health needs and face significant obstacles when accessing health care. Hypertension can be a rough predictor of health care access; increased levels may reflect barriers to care. It is unknown whether problems stem from a lack of health insurance, as PEH enrollment data are scant, particularly in non-Medicaid expansion states. To begin to address existing literature gaps, we surveyed insurance status and collected blood pressure (BP) measurements of PEH presenting to a free clinic in Miami-Dade County, Florida. Study Design: We present trends from retrospective cohort data that include insurance status information and BP measurements obtained from 200 PEH receiving care at a free clinic. Methods: Recruitment encounters took place over 1 year. Participants were approached about the option of using deidentified data for research purposes and informed consent was obtained prior to being included in the study. Deidentified data were collected and stored in a Health Insurance Portability and Accountability Act-compliant REDCap then downloaded and analyzed in R 4.3.2. Results: A majority (61%) of PEH were insured. Mean (SD) systolic BP of uninsured PEH was 141.0 (23) mm Hg vs 135.4 (22) mm Hg for insured PEH. Independent 2-tailed t test found the mean systolic BP of insured PEH to be significantly lower than that of uninsured PEH (P = .00035). After stratifying the cohort into 10-year age groups (eg, 30-39 years, 40-49 years, etc), we discovered that uninsured participants aged 50 to 59 years had significantly increased systolic and diastolic BP. Conclusions: Insured PEH had lower systolic BP, despite an older mean age. After age stratification, a difference remained for those aged 50 to 59, representing the largest sample and oldest age group without Medicare. Still, the mean BP of insured PEH was elevated within range of hypertension, indicating that there are other barriers limiting the ability of PEH to access health care and that improvement is unlikely to be achieved solely by increasing insurance enrollment. Future studies should investigate additional factors, including why insured PEH choose free clinic care. [ABSTRACT FROM AUTHOR]

Background: There is a growing movement to increase palliative care consults from the emergency department (ED) to reduce healthcare costs and improve quality of life. The surprise question is a screening tool that emergency medicine physicians may be able to use towards achieving this goal.Objective: The objectives of this study were to increase awareness of hospice and palliative care medicine (HPM) among emergency medicine (EM) providers and to evaluate whether this heightened awareness increased palliative care consults among participating emergency medicine providers.Methods: We conducted an anonymous convenience sample survey and two educational interventions about HPM including the surprise question among emergency medicine resident and attending physicians at a large urban public academic quaternary care center from July to November 2018. A report of palliative care consults ordered between August 1, 2017 and January 1, 2019 was generated from the electronic health records used by the hospital. The number of palliative care consults made before and after the educational intervention was compared.Results: After the first educational intervention centered on the surprise question, palliative care consults from the ED increased from an average of 2.25 per month (range 0 to 8, SD: 2.38) to 12.67 per month (range 9 to 19, SD: 4.01, p < .001).Conclusion: Educating EM physicians about the surprise question can increase the number of palliative care consults from the ED, thereby potentially improving patient care and decreasing costs by avoiding unwanted healthcare interventions.

Background: Thoracolumbar (TL) injury is a common finding in the severely injured multi-trauma patient. However, the incidence and pattern of TL injury in patients with milder trauma is unclear.Objective: The aim of this study was to collect and analyze evidence for the development of a clinical decision rule (CDR) to evaluate the TL spine in patients with non-severe blunt trauma and avoid dedicated imaging in low-risk cases.Methods: Adult patients with blunt trauma who presented to a major academic center (May 2016 to October 2017) and received dedicated imaging of the TL spine were included. Exclusion criteria consisted of any coexisting condition preventing the acquisition of history or examination. The primary endpoint is TL spine injury requiring orthopedic evaluation, bracing/orthosis, or surgery. Preliminary CDR derivation was performed with recursive partitioning.Results: Of 4612 patients screened, 1049 (22.7%) met inclusion criteria. Thirty-six (3.4%) patients were found to have TL spine injury, of which 88.9% received spinal bracing, orthosis, or surgery. Absence of midline tenderness conveyed the highest negative predictive value, followed by a non-severe mechanism of injury, lack of neurologic examination findings, and age < 65 years. No patients in this cohort with these four findings had a TL spine injury.Conclusions: In certain lower-risk blunt trauma patients < 65 years of age, focused examination combined with mechanism of injury may be highly sensitive (100%) to rule out TL injury without the need for dedicated imaging. However, validation is necessary, given multiple study limitations. Potential instrument to screen for TL injury in minor trauma: TL injury is unlikely if all four of the following are present: 1) no midline back tenderness or deformity, 2) no focal neurologic signs or symptoms or altered mentation, 3) age < 65 years; and 4) lack of severe mechanism of injury, for example, fall greater than standing, motor-vehicle collision with rollover/ejection/pedestrian or unenclosed vehicle, and assault with a weapon.

Emergency department presentations of syncope can vary from benign to life-threatening etiologies. Older patients are at increased risk of cardiac causes of syncope. Ventricular standstill is a rare phenomenon that can manifest as syncope and must be correctly identified and promptly treated to prevent sudden cardiac arrest. We report the case of a 70-year old man with dizziness and convulsive syncope whose initial ECG showed a right bundle branch block, but then developed ventricular standstill and intermittent high-grade AV block while still in the ED. He was transferred to the ICU and underwent pacemaker implantation. A high index of suspicion for dysrhythmias should be maintained for any patient presenting to the ED with high-risk syncope., (Copyright © 2019 Elsevier Inc. All rights reserved.)

En: Although infection rates and the impact of infection on hospital emergency departments (EDs) are known or can be reliably estimated, the incidence and prevalence of sepsis vary in relation to which definitions or registers used. Sepsis is also well known to be under-diagnosed by physicians in general and by ED physicians in particular. Over half of sepsis cases are community-acquired, and 50% to 60% of patients in intensive care units (ICUs) with sepsis or septic shock are admitted directly from the ED. Pneumonia and urinary tract infections are the most common points of focus in sepsis, septic shock, bacteremia, and ED admissions to the ICU for infectious processes. For this article a multinational group of experts representing Latin American emergency medicine associations reviewed and analyzed similarities and differences in the epidemiology of sepsis in different geographic locations. We consider key aspects and geographic similarities and differences in the early identification of patients with severe sepsis; criteria that define the diagnosis; appropriate early antibiotic and fluid therapy; the roles of triage systems and multidisciplinary sepsis code units; and the use of biological markers in this time-dependent disease. We also discuss key points and strategies for improving the diagnosis, prognosis, and care of sepsis patients in the ED.
