Quality of publications in emergency medicine

OBJECTIVE The objective of this study is to describe emergency medicine (EM) publications in terms of methodology, approval by institutional review board, method of consent, external validity, and setting (eg, prehospital or emergency department). METHODS The 12 top-ranked emergency journals were selected. We manually reviewed the last 30 original articles in each EM journal, to represent more than 2 months of publications for all EM journals (range, 2-6 months). Only clinical original articles on human subjects were included. To ensure accurate data transcription, each article was read at least twice by 2 different reviewers and graded by written criteria using an extraction standard chart. RESULTS Over the articles reviewed, 330 were analyzed. One hundred eighty-nine (57.3%) were prospective studies; 29 (8.8%) were randomized studies. Two hundred twenty-six studies (68.5%) mentioned an institutional review board approval or a waiver of authorization, and an informed consent was not mentioned in 227 (68.8%) of studies. Fifty-nine (17.9%) were conducted in a prehospital setting. Two hundred thirty-eight (72.1%) of these studies were at single-center institutions; the Unite States contributed 158 (47.9%) of the total publications. CONCLUSION This study describes publications in the field of EM. Randomized studies represent 9% of publications, most studies are cross-sectional, and more than half have a retrospective design. We found that, in one-third of the studies, an institutional review board review was not mentioned and informed consent was not specified in two-thirds of the studies. Emergency medicine research volume, quality, and grants activity must increase in order for EM to progress within academic medicine.

Use of intravenous lipid 20% emulsion for the treatment of a voluntary intoxication of flecainide with refractory shock

The use of intravenous fat emulsion (IFE) has been well described in a systematic review of human and animal studies. 1 Cases of successful early use of lipid emulsion for cardiotoxic effects induced by local anesthetics or other lipophilic drugs, such as calcium-channel antagonists or beta-blockers, have recently been published. 2,3 We report the fi rst case of IFE therapy for the treatment of a voluntary fl ecainide poisoning with refractory shock. A 72-year-old French female patient, whose main medical history included a rhythmic heart disease treated with fl ecainide and a depressive syndrome with multiple suicide attempts, was rescued at home by a fi rst-aid team after voluntarily ingesting drugs. At the scene, an empty plate of 15 tablets of fl ecainide (100 mg), a plate of 15 tablets of oxazepam (10 mg), and a plate of 30 tablets of levothyroxin (50 μ g) were found; the time of ingestion was unknown. The patient was taken to the intensive care unit of the nearest hospital. Clinical examination revealed a drowsy patient, with an enolic breath and without coma. Respiratory rate was 30 breaths per minute, oxygen saturation was 88% without oxygen supply, blood pressure was 70/50 mmHg, and heart rate was 55 beats per minute. An electrocardiogram revealed a widening of QRS complexes longer than 0.2 sec with a prolongation of the QT interval. However, despite being treated with aggressive supportive care, including fl uid resuscitation (750 mL of 4.2% sodium bicarbonate with hydroxyethyl starch 1500 mL), mechanical ventilation, and an increasing dose of vasopressors (up to 6 mg/h of epinephrine), it was decided to transfer her to the university reference hospital for the possible implementation of circulatory assistance. After the failure of conventional pharmacological therapy and regarding the similarities of fl ecainide with molecules of the class of local anesthetics from the electrophysiological point of view, 4 an infusion of Intralipid ® 20% in the form of a bolus of 1.5 mL/kg associated with a continuous infusion of 0.25 mL/min was started. The patient was then transferred with a medical team (emergency physician, nurse, and ambulance driver) to the university hospital. During the following 30 min, hemodynamic stabilization allowed a dramatic decrease in the dose of epinephrine (1 mg/h during the transfer) without any further complication. On arrival at the reference hospital, the patient ’ s blood pressure was 111/80 mmHg and her pulse rate was 75 beats per minute. An ECG showed a marked shortening of the QRS complexes. The evolution was a progressive hemodynamic improvement without implementation of circulatory assistance. After 20 days of hospitalization in ICU because of aspiration pneumonia, the patient was weaned from oxygen therapy without after effects. She was secondarily hospitalized in a psychiatric unit for the management of her major depressive disorder. According with De Roock, 5 who reminds us that lipid emulsion therapy does not entirely fulfi ll the criteria for antidotal therapy, this case is a reminder that lipid emulsions should be considered as a second-line treatment for poisonings with cardiotropic drugs after conventional treatment and can even be used during medical transfer between two hospitals.

User satisfaction with maritime telemedicine

We assessed the satisfaction of onboard caregivers with the maritime telehealth service provided by the Centre de Consultations Médicales Maritimes (CCMM). We conducted a survey of captains and caregivers by email. Of the 385 surveys sent out, 165 (43%) were completed. Eighty four percent of responders (n = 110) thought that waiting time was satisfactory or very satisfactory, and 97% (n = 128) were satisfied or very satisfied with their relationship with the remote physician. Thirty eight per cent of participants (n = 50) considered that the physician understood the medical problem very well; understanding was good in 58% of cases (n = 76) and bad in only 4% of cases (n = 5). Sixty two per cent of participants (n = 83) sent pictures before consultation. The respondents were also satisfied with the telephone advice overall, the competence of the physicians providing the advice, the length of time spent waiting, the verbal prescription and the medical advice given. Onboard caregivers were generally well satisfied with the maritime teleconsultations and the advice provided by the CCMM physicians.

Levocetirizine and Prednisone Are Not Superior to Levocetirizine Alone for the Treatment of Acute Urticaria: A Randomized Double-Blind Clinical Trial

Study objective We evaluate the efficacy of a 4‐day course of prednisone added to antihistamine for the management of acute urticaria in an emergency department (ED). Methods In this double‐blind randomized clinical trial, patients were eligible for inclusion if aged 18 years or older and with acute urticaria of no more than 24 hours’ duration. Patients with anaphylaxis or who had received antihistamines or glucocorticoids during the previous 5 days were not included. In addition to levocetirizine (5 mg orally for 5 days), patients were assigned to receive prednisone (40 mg orally for 4 days) or placebo. The primary endpoint of the study was itching relief 2 days after the ED visit, rated on a numeric scale of 0 to 10. Secondary endpoints were rash resolution, relapses, and adverse events. Results A total of 100 patients were included, 50 in each group. Seven patients in the prednisone group and 8 in the placebo group discontinued treatment. At 2‐day follow‐up, 62% of patients in the prednisone group had an itch score of 0 versus 76% of those in the placebo group (&Dgr; 14%; 95% confidence interval –31% to 4%). Thirty percent of patients in the prednisone group and 24% in the placebo group reported relapses (&Dgr; 6%; 95% confidence interval –23% to 11%). Mild adverse events were reported by 12% of patients in the prednisone group and 14% in the placebo group. Conclusion The addition of a prednisone burst did not improve the symptomatic and clinical response of acute urticaria to levocetirizine. This study does not support the addition of corticosteroid to H1 antihistamine as first‐line treatment of acute urticaria without angioedema.

Suicide attempt by intravenous potassium self-poisoning: a case report.

Introduction. Overdose of potassium is not as frequently encountered in clinical practice as hyperkalaemia due to acute or chronic renal disease. However, potassium overdoses leading to serious consequences do occur. Case Presentation. A 20-year-old nurse student presented with a cardiac arrest with asystole rhythm. Beside the patient were found four 50-mL syringes and empty vials of potassium chloride (20 mL, 10%). After initial resuscitation with epinephrine, 125 mL of a 4.2% intravenous solution of sodium bicarbonate were injected which resulted in the recovery of an effective cardiac activity. The patient recovered without sequelae. Conclusion. The difficulty in this case was to recognize the potassium poisoning. The advanced resuscitation with the use of a specific treatment helped to resuscitate the patient.

Added value of sending photograph in diagnosing a medical disease declared at sea: experience of the French Tele-Medical Assistance Service

The maritime medical tele-consultation carried out by a doctor from the Toulouse Tele-Medical Assistance Service is currently based on tele-consultation using radiotelegraphy and the complementary transmission of data (photographs, electrocardiogram) via the Internet. In a previous article, we presented the benefits of photograph transmission for trauma management in isolated areas. Through this new series of cases, we wanted to expose the aspect of the medical pathologies and the contribution of sending photographs in their management. CASE REPORTS Case 1. Myocardial infarction. Case 2. Toxic epidermal necrolysis. Case 3. Tooth abscess. Case 4. Shingles. Case 5. Junctional tachycardia. The tele-transmission of photographs provides a real diagnostic and follow-up tool for patients suffering from medical pathologies. The constant increase in the number of tele-consultations with the exchange of photographs shows its necessity and the interest of the participants in the development of these technologies.

Benefits of photograph transmission for trauma management in isolated areas: cases from the French tele-medical assistance service

French maritime tele-medical assistance is currently performed by a telephone consultation associated with complementary transmission of data (photographs, electrocardiograms, etc.) over the internet. Five case reports are presented to illustrate how photo transmission is useful to managing initial care and monitoring isolated patients. Case reports included: Case 1: management of a hand burn; Case 2: management of a finger wound; Case 3: management of an ocular foreign body; Case 4: management of a subungual haematoma; Case 5: management of phlegmon. In conclusions, photo transmission improves our practice of maritime tele-medical medicine. New high-definition technologies will help in the development of videoconferences on ships.

French maritime procedures concerning the Ebola infection, experience of the French Tele-Medical Assistance Service (TMAS)

INTRODUCTION Since Ebola worldwide infection, the Centre de Consultation Medicale Maritime (CCMM), French maritime Tele-Medical Assistance Service (TMAS), has been widely involved; this on request of the French Directorate for Maritime Affairs (Ministry for Ecology and Transport), to implement recommendations. Several procedures have been developed jointly with the Directorate for Maritime Affairs (DAM), the Maritime Health Service (SSGM), the Directorate of Health (DGS) and the French maritime TMAS. In this letter, we present and discuss those procedures.

Using D-Dimer to Diagnose Painless Acute Aortic Dissection: A Case Report

Introduction. Aortic dissection is a cardiovascular emergency; the most frequent symptom is chest pain, but clinical presentation can be varied and atypical. Case Presentation. We report the case of a 66-year-old Caucasian male who presented a syncope immediately followed by a left-arm weakness while driving his car. Clinical examination was normal, but bilateral jugular vein distension was noted. Electrocardiogram and chest radiography were unremarkable. Among blood tests performed, troponin I test result was negative, and D-dimer test concentration was >4000 ng/mL. Since D-dimer test result was positive, chest computer tomography angiogram was performed and found a thoracic aortic dissection. Conclusion. Our case report shows that acute aortic dissection diagnosis is difficult and must be associated with the interpretation of various clinical signs and D-dimer measurement. It could be helpful for the emergency physician to have a pretest probability D-dimer like in pulmonary embolism diagnosis.
