  Patients with anorectal complaints commonly present to the emergency department (ED). In patients with prior history of pelvic radiation and those with risk factors for sexually transmitted infections, proctitis is frequently on the differential diagnosis. Computed tomography (CT) scans are frequently done in patients with atypical presentations and those with broader differential diagnoses. Although in cases with suspected uncomplicated proctitis, conducting a point-of-care transperineal ultrasound (TPUS) may provide sufficient data to confirm the diagnosis and ascertain a safe plan for outpatient management, thus limiting the need for CT scan, a frequent flow-limiting step in the ED.
 
  In this article, we present a brief case series of patients presenting to the ED with anorectal complaints in whom TPUS revealed circumferential symmetric rectal wall edema and pericolonic stranding suggestive of proctitis. History and subsequent imaging further supported these diagnoses; we also briefly detail the patientsWHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? We propose the use of TPUS as the screening imaging for anorectal pathologies and those with suspected proctitis to increase its use among emergency physicians. We review the main sonographic features of proctitis alongside reports from clinical cases, as well as the potential advantages of TPUS as a first-line imaging modality as compared with CT or magnetic resonance imaging. Although the complexities of anorectal anatomy can make TPUS a more difficult ultrasound modality to master, integrating TPUS into clinical practice will prove beneficial to both physician and patient.
  The catastrophic fail of a container holding a pressure-liquified gas can generate a boiling liquid expanding vapor explosion (BLEVE) with a subsequent blast wave, flying fragments, and fire or toxic gas release.
 
  This report describes the management of a mass casualty disaster related to a BLEVE in an urban area due to a highway accident involving a tanker carrying liquified petroleum gas and a truck transporting chemical solvents. The event resulted in 158 casualties that were triaged, stabilized, and transported into the "hub" and "spoke" hospitals of the regional trauma network within 3h and 22min from the event by the Emergency Medical Services. The logistic complications related to the partial collapse of the highway bridge on an underlying urban road and the relative solutions adopted, as well as the application and advantages of the use of the Simple Triage and Rapid Treatment (START) algorithm in the field and the criteria adopted for the distribution of patients within the trauma network, are dism in the field and the criteria adopted for the distribution of patients within the trauma network, are discussed, along with the potential pitfalls observed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? BLEVE events are rare but can be complex in both logistical management and clinical presentation of the lesions related to the event. The START algorithm is a valuable tool for rapid triage in mass casualty incidents.This case report describes a child who developed Pott's puffy tumor and was treated at the Children's Mercy Hospital in Kansas City. In addition to a discussion of a case, a review of the literature was completed on this topic describing the typical embryology and development of the frontal sinus, and the epidemiology, diagnosis, and treatment of Pott's puffy tumor. The patient was a 23-month-old boy who developed Pott's puffy tumor after recovery from influenza. The patient presented to the hospital with progressing edema of the unilateral eye that spread bilaterally within a few days. A CT scan demonstrated pansinusitis, developed frontal sinuses, right periorbital cellulitis, and medial forehead subperiosteal abscess. Functional endoscopic sinus surgery and transcutaneous abscess drainage were urgently performed and the patient made a full recovery following a course of ertapenem and levofloxacin. The presence of a developed frontal sinus in a 23-month-old is an unexpected radiologic finding. This case represents the youngest patient reported in the literature to develop this rare complication of frontal sinusitis.
  Consultation skills are essential to clinical practice and, when effective, can facilitate diagnoses and improve patient satisfaction. Various models exist to facilitate consultation teaching.  https://www.selleckchem.com/products/lenalidomide-s1029.html  These can be prescriptive, a challenge to apply in clinical settings and are often designed for primary care. In redesigning our entire curriculum, we sought to create a new visual, digital, resource for consultation teaching, aligned with statements from the UK Council for Clinical Communication (UKCCC), and suitable for the evolving expectations of patients, clinicians and the UK NHS, in 21st century medicine.
 
  We conducted a literature review encompassing teaching methods, NHS Priorities, patients' priorities, lifestyle interventions and practitioner resilience. COGConnect was designed iteratively through consultation with a graphic designer, health psychologists, a range of clinicians, and a consultation expert, and has evolved through extensive use in our new "effective consulting" course in primary and secondares a strong visual resource suitable for digital learning. It offers greater emphasis on explicit clinical reasoning, activation of patient self-care and learning from the interaction. Having become the de facto resource for consultation skills training across primary and secondary care in our institution, the next phase is to develop the COGConnect.info website and a programme of formal evaluation.
  To elucidate whether Amazon's virtual assistant, Alexa, provides evidence-based support as a supplement to provider-facilitated prenatal care, during the COVID-19 pandemic.
 
  Using a conceptual content analysis approach, a query of 40 questions, relating to all phases of pregnancy, was collected from Alexa by two independent investigators, using two unique devices, over a one-week period between May 20, 2020 and May 27, 2020. Alexa's responses were matched to the evidence-based content from the American College of Obstetricians and Gynecologists (ACOG) and reviewed by a Certified Nurse Midwife for completeness and currency.
 
  Of the 40 questions asked of Alexa, it was unable to answer 14 questions (35%). A total of 21 out of the 40 responses (52%) were not evidence-based and three COVID-specific questions (about 1%) were answered incorrectly or insufficiently. Four questions (10%) were answered accurately.
 
  Alexa was largely unable to provide evidence-based answers to commonly asked pregnancy questions and, in many cases, supplied inaccurate, incomplete, or completely unrelated answers that could further confuse health consumers.
