Ramsay Hunt syndrome is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus infection occurs in the geniculate ganglion, causing otalgia, auricular vesicles and peripheral facial paralysis. Because these symptoms do not always present at the onset, this syndrome can be misdiagnosed. We report the case of a patient who was diagnosed with simple otitis externa after presenting to the emergency department (ED) with a 3-day history of rightsided otalgia. Her condition subsequently evolved to include right-sided auricular vesicles and right-sided facial weakness. She presented to the ED again after 2 days and was correctly diagnosed with Ramsay Hunt syndrome. We describe the clinical presentation, diagnostic findings and management of this uncommon but important entity. [ABSTRACT FROM AUTHOR]

OBJECTIVES: We sought to determine the emergency medicine training demographics of physicians working in rural and regional emergency departments (EDs) in southwestern Ontario. METHODS: A confidential 8-item survey was mailed to ED chiefs in 32 community EDs in southwestern Ontario during the month of March 2005. This study was limited to nonacademic centres. RESULTS: Responses were received from 25 (78.1%) of the surveyed EDs, and demographic information on 256 physicians working in those EDs was obtained. Of this total, 181 (70.1%) physicians had no formal emergency medicine (EM) training. Most were members of the College of Family Physicians of Canada (CCFPs). The minimum qualification to work in the surveyed EDs was a CCFP in 8 EDs (32.0%) and a CCFP with Advanced Cardiac and Trauma Resuscitation Courses (ACLS and ATLS) in 17 EDs (68.0%). None of the surveyed EDs required a CCFP(EM) or FRCP(EM) certification, even in population centres larger than 50 000. CONCLUSION: The majority of physicians working in southwestern Ontario community EDs graduated from family medicine residencies, and most have no formal EM training or certification. This information is of relevance to both family medicine and emergency medicine residency training programs. It should be considered in the determination of curriculum content and the appropriate number of residency positions. [ABSTRACT FROM AUTHOR]

Background: Competence committees play a key role in a competency-based system of assessment. These committees are tasked with reviewing and synthesizing clinical performance data to make judgments regarding residents' competence. Canadian emergency medicine (EM) postgraduate training programs recently implemented competence committees; however, a paucity of literature guides their work., Objective: The objective of this study was to develop consensus-based recommendations to optimize the function and decisions of competence committees in Canadian EM training programs., Methods: Semi-structured interviews of EM competence committee chairs were conducted and analyzed. The interview guide was informed by a literature review of competence committee structure, processes, and best practices. Inductive thematic analysis of interview transcripts was conducted to identify emerging themes. Preliminary recommendations, based on themes, were drafted and presented at the 2019 CAEP Academic Symposium on Education. Through a live presentation and survey poll, symposium attendees representing the national EM community participated in a facilitated discussion of the recommendations. The authors incorporated this feedback and identified consensus among symposium attendees on a final set of nine high-yield recommendations., Conclusion: The Canadian EM community used a structured process to develop nine best practice recommendations for competence committees addressing: committee membership, meeting processes, decision outcomes, use of high-quality performance data, and ongoing quality improvement. These recommendations can inform the structure and processes of competence committees in Canadian EM training programs.

Twenty two isolates of Pasteurella multocida were obtained from different tissues of dead birds and animals (cattle, buffalo, sheep, and goat) suspected of fowl cholera and haemorrhagic septicaemia. The isolates were confirmed as P. multocida by various biochemical tests and PM PCR. An attempt was made to standardize Loop mediated isothermal amplification (LAMP) using newly designed primer sequences of KMT1 gene. Loop mediated isothermal amplification was conducted using 6 sets of primers at 65°C for 30 minutes and the result was confirmed by visual observation using SYBR green fluorescence dye as marker of positive reaction under UV transilluminator. On electrophoretic analysis of the products on 2% agarose gel, a ladder like pattern was observed, which suggested a positive amplification, whereas no amplification was observed in negative controls. Additionally, product of positive reaction yielded a green fluorescence following addition of SYBR green under UV transilluminator. It was observed that LAMP is a more sensitive test than polymerase chain reaction (PCR), as the former could detect DNA to lower limit of 22.8 pg/µl, while the latter could detect DNA to lower limit of 2.28 ng/ µl, thus LAMP could detect 100 times lesser concentration of DNA in comparison to PCR. Loop mediated isothermal amplification is a rather newer molecular technique, which can be used for rapid detection of infectious agent at field level and which does not require sophisticated instrument, i.e. thermal cycler. Furthermore, unlike the conventional PCR technique, LAMP requires lesser time to perform and result can be read visually.

Introduction: Several agents can be administered during procedural sedation and analgesia (PSA) in the emergency department (ED). The purpose of this study was to determine the PSA agents commonly used by physicians working in nontertiary EDs, and to assess the physicians' comfort level administering the agents as well as their knowledge of adverse effects of the agents., Methods: We distributed a confidential electronic survey to physicians working in nontertiary EDs in southwestern Ontario. Using a 5-point Likert scale, ED physicians were asked to rate their use of older and newer agents used for PSA in the ED, as well as their familiarity with the agents., Results: A total of 55 physicians completed the survey. The most frequently used drugs were fentanyl (66.0% often or always) and propofol with fentanyl (59.2% often or always). Most respondents stated that they rarely used ketofol (54.2% rarely or never) or etomidate (77.1% rarely or never). Respondents were most comfortable using midazolam or fentanyl (96.1% somewhat or very comfortable), and least comfortable administering etomidate and ketofol (36.5% and 23.1% somewhat or very uncomfortable). These differences were magnified with comparison of physicians with CCFP (Certification in The College of Family Physicians) and CCFP(EM) (emergency medicine) designations. Additionally, etomidate's adverse effects were the least astutely recognized (19%), compared with midazolam combined with fentanyl (63%)., Conclusion: Physicians practising in nontertiary EDs used more often, remained more comfortable with and were more familiar with older sedation agents than newer agents.

Introduction: Pulmonary embolism (PE) is a serious condition with mortality estimates of up to 10%. We sought to investigate the diagnosis of PE, time to access imaging and diagnostic utility of each modality in a rural emergency department (Ed)., Methods: We completed a retrospective chart review to determine the investigations performed and treatments initiated in the management of suspected PE in a rural hospital., Results: A total of 47 charts from a 5-year period were reviewed. Of these, 83.0% indicated a D-dimer test was ordered, and 31.9% and 40.4% indicated either ventilation-perfusion (V/Q) or computed tomography (CT) were ordered during the ED visit. Computed tomography diagnosed 11 of the 12 instances of confirmed PE. Mean time to patients undergoing V/Q or CT was 1.58 and 1.59 days, respectively. Low-molecular-weight heparin was started in 83.0% of patients., Conclusion: In this ED there may be over reliance on the D-dimer test, irrespective of Wells score. Access to V/Q and CT were similar to that of an urban centre. Empiric anticoagulation was started in most patients., (© 2012 Society of Rural Physicians of Canada)

Introduction: We sought to determine the perceptions of physicians staffing rural emergency departments (EDs) in southwestern Ontario with respect to factors affecting patient care in the domains of physical resources, available support and education., Methods: A confidential 30-item survey was distributed through ED chiefs to physicians working in rural EDs in southwestern Ontario. Using a 5-point Likert scale, physicians were asked to rate their perception of factors that affect patient care in their ED. Demographic and practice characteristics were collected to accurately represent the participating centres and physicians., Results: Twenty-seven of the 164 surveys distributed were completed (16% response rate). Responses were received from 13 (81.3%) of the 16 surveyed EDs. Most of the respondents (78%) held CCFP (Certificant of the College of Family Physicians) credentials, with no additional emergency medicine training. Crowding from inpatient boarding, and inadequate physician staffing or coverage in EDs were identified as having a negative impact on patient care. Information sharing within the hospital, access to emergent laboratory studies and physician access to medications in the ED were identified as having the greatest positive impact on patient care. Respondents viewed all questions in the domain of education as either positive or neutral., Conclusion: Our survey results reveal that physicians practising emergency medicine in southwestern Ontario perceive crowding as the greatest barrier to providing patient care. Conversely, the survey identified that rural ED physicians perceive information sharing within the hospital, the availability of emergent laboratory studies and access to medications within the ED as having a strongly positive impact on patient care. Interestingly, our findings suggest that physicians in rural EDs view their access to education as adequate, as responses were either positive or neutral in regard to access to training and ability to maintain relevant skills.

Respiratory dyskinesia is an under-recognized side effect of neuroleptic administration. There are only few studies that have addressed the prevalence of respiratory dyskinesia in patients with tardive dyskinesia. Our case report highlights the need to regularly examine patients on antipsychotics for any evidence of dyskinetic movements including respiratory musculature. Since RD is underrecognized and misdiagnosed, early detection can improve long term prognosis as treatment options are few and usually of only limited effect. A 62-year-old Asian male, retired civil engineer, had more than 20 years history of depressive illness, developed antidepressant induced hypomania, and was given risperidone upto 1 mg per day. He developed extrapyrmidal side effects as tremors, rigidity and later dyskinetic movements of lips with shortness of breathing, dyspnoea, grunting or gasping. He was referred to the pulmonologist who got the neccessary medical work up done, which was normal. A diagnosis of respiratory dyskinesia was made. Respiratory dyskinesia is an under-recognised and distressing condition that clinicians need to be aware of when treating patients with anti-psychotic medications. And also there is a need to regularly examine patients on antipsychotics for any evidence of dyskinetic movements including respiratory musculature for early diagnosis and better outcome. This case report also is worth reading for professionals of other specialties also because of the presentation of this patient, it can be easily misdiagnosed and result in poor outcome.

Pigmented villonodular synovitis is a synovial proliferative disorder that remains a diagnostic difficulty. Many clues in the history, physical examination, and radiographic studies can aid in the diagnosis. A patient in the third or fourth decade of life often will present with vague monoarticular complaints. Symptoms include intermittent, extreme deep pain localized to the hip, occasionally relieved by position. Decreased active and passive range of motion may be found. Small erosions in the head of the femur and acetabulum may occur early in the course of the disease. Magnetic resonance imaging is the imaging modality of choice and will show the characteristic findings of a joint effusion, synovial proliferation, and bulging of the hip. The synovial lining has a low signal on T1- and T2-weighted images, secondary to hemosiderin deposition. Pigmented villonodular synovitis should be included in the differential diagnosis of young patients with unexplained hip pain.

Pigmented villonodular synovitis is an uncommon disease that remains a diagnostic challenge. Presenting complaints commonly involve one joint, most often the knee or hip. Symptoms of pain and swelling characteristically have an insidious onset and are slowly progressive. The physical examination may be completely normal. Radiographs of the knee may appear normal or may show a periarticular soft tissue density, expansion of the suprapatellar pouch and local osseous changes confined to the patellofemoral articulation. Radiographs of the hip may show erosions in the head and neck of the femur and acetabulum. Magnetic resonance imaging usually demonstrates key diagnostic features, which include joint effusion, elevation of the joint capsule, hyperplastic synovium and low signal intensity resulting from hemosiderin deposition. The diagnosis of pigmented villonodular synovitis is confirmed by biopsy, and the treatment of choice is synovectomy.

Mice deficient in the Flk-1 receptor tyrosine kinase are known to die in utero because of defective vascular and hematopoietic development. Here, we show that flk-1(-/-) embryonic stem cells are nevertheless able to differentiate into hematopoietic and endothelial cells in vitro, although they give rise to a greatly reduced number of blast colonies, a measure of hemangioblast potential. Furthermore, normal numbers of hematopoietic progenitors are found in 7.5-day postcoitum flk-1(-/-) embryos, even though 8. 5-day postcoitum flk-1(-/-) embryos are known to be deficient in such cells. Our results suggest that hematopoietic/endothelial progenitors arise independently of Flk-1, but that their subsequent migration and expansion require a Flk-1-mediated signal.
