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. [ABSTRACT FROM AUTHOR]

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]

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.

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.

Objective: To calculate the emergency department (ED)-level Escherichia coli percentage of isolates susceptible to commonly used antibiotics and to determine the risk factors associated with inadequate empiric antibiotic therapy among patients treated for urinary tract infections (UTIs) in our ED.Methods: Retrospective cohort study conducted at a large tertiary teaching hospital. Participants included patients older than 18years of age who had a urine culture with growth of >100,000 colonies of E. coli. Demographic and therapeutic choices associated with inadequate empiric antibiotic therapy were explored. Antimicrobial susceptibility pattern of E. coli isolates recovered from ED patients were calculated, and stratified by gender and age.Results: A total of 300 unique patients had E. coli bacteriuria during the study period. Among patients who received at least one dose of antibiotic in the ED, variables independently associated with an increased risk of inadequate empiric therapy were age (relative risk [RR] 1.016; 95% confidence interval [CI] 1.001-1.031; P=0.032), male gender (RR 2.507; 95% CI 1.470-4.486; P=0.001), and use of fluoroquinolones (RR 2.128; 95% CI 1.249-3.624 P=0.005). Sub-group analysis of patients discharged from the ED showed that definitive therapy with nitrofurantoin decreased the risk of inadequate empiric antibiotic therapy by 80% (RR 0.202; CI 0.065-0.638; P=0.006). ED-level antibiograms showed differences in antimicrobial susceptibility of E. coli by age and gender.Conclusions: Development of ED-level antimicrobial susceptibility data and consideration of patients' clinical characteristics can help better guide selection of empiric antibiotic therapy for the treatment of UTIs.

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.
