1/130. Localized tetanus in a child.The majority of physicians in practice today in developed countries have never seen a case of tetanus. The last pediatric case reported in canada occurred in 1992. We present the case of a child who had localized tetanus despite previous partial immunization.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/130. Emergency department presentations of cerebrovascular disease in children.Five cases of children with cerebrovascular disease presentations to the emergency department (ED) were selected as a series to illustrate the variety of presentation of cerebrovascular disease in children. This series shows that although cerebrovascular disease in children is uncommon, it is likely that cases will occasionally present acutely to an ED. The emergency physician's role in the management of suspected acute strokes in children is that of immediate stabilization, imaging to rule out hemorrhage, other studies to rule out emergent acute disease, and timely consultation for further management. Computed tomography (CT) is useful to detect an acute hemorrhage or old ischemic lesion. magnetic resonance imaging has superior image resolution over CT, but CT may be more practical initially. magnetic resonance angiography is a useful part of the stroke workup in children.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/130. Small ruptured abdominal aneurysm diagnosed by emergency physician ultrasound.Ruptured abdominal aortic aneurysms currently have a high rate of both mortality and misdiagnosis. Aneurysms smaller than 4 cm are not commonly considered for surgical repair. This report describes the case of a ruptured abdominal aneurysm measuring less than 4 cm diagnosed by the emergency physician utilizing bedside ultrasound. Within 30 minutes of arrival at the emergency department the patient's abdominal pain resolved spontaneously after defecation. If the bedside ultrasound had not been performed it is possible the patient would have been discharged from the hospital without surgical intervention. Bedside ultrasound by emergency physicians may improve the diagnosis of ruptured aortic aneurysms, particularly if the presentation is atypical.- - - - - - - - - - ranking = 6keywords = physician (Clic here for more details about this article) |
4/130. Expeditious diagnosis of primary prosthetic valve failure.Primary prosthetic valve failure is a catastrophic complication of prosthetic valves. Expeditious diagnosis of this complication is crucial because survival time is minutes to hours after valvular dysfunction. The only life-saving therapy for primary prosthetic valve failure is immediate surgical intervention for valve replacement. Because primary prosthetic valve failure rarely occurs, most physicians do not have experience with such patients and appropriate diagnosis and management may be delayed. A case is presented of a patient with primary prosthetic valve failure. This case illustrates how rapidly such a patient can deteriorate. This report discusses how recognition of key findings on history, physical examination, and plain chest radiography can lead to a rapid diagnosis.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/130. The electrocardiographic diagnosis of acute myocardial infarction in patients with ventricular paced rhythms.The electrocardiographic diagnosis of ischemic heart disease is more difficult in the setting of ventricular-paced rhythms (VPR). ST segment/T wave configurations are changed by the altered intraventricular conduction associated with ventricular pacing. The anticipated, or expected, morphology in patients with VPR is one of QRS complex-ST segment/T wave discordance. An awareness of the anticipated ST segment morphologies of VPR is mandatory for the emergency physician. This knowledge is not dependent on additional diagnostic testing, medical records, or expertise in pacemaker function. Two cases are presented in which an analysis of the electrocardiogram in the setting of VPR assisted the treating physicians in establishing the correct diagnosis of acute myocardial infarction and arranging for urgent revascularization.- - - - - - - - - - ranking = 2keywords = physician (Clic here for more details about this article) |
6/130. The efficacy of integrating "smart simulated casualties" in hospital disaster drills.INTRODUCTION: Full-scale disaster drills are complex, expensive, and may involve hundreds or thousands of people. However, even when carefully planned, they often fail to manifest the details of medical care given to the casualties during the drill. OBJECTIVE: To assess the feasibility of integrating physicians among the simulated casualties of a hospital disaster drill. methods: A total of 178 physicians graduating an Advanced Trauma life Support (ATLS) course participated in eight hospital disaster drills during 1994 as "Smart Victims." The participants were given cards with descriptions of their injury and detailed instructions on how to manipulate their medical condition according to the medical care provided in the hospital. They also were given coded questionnaires to fill out during the process of the drill. Conclusions were drawn from analysis of the questionnaires and from a roundtable discussion following each drill. RESULTS: The "smart casualties" made comments on the following topics: 1) triage (over-triage in 9%, and under-triage in 4%); 2) treatment sites; 3) medical equipment usage (i.e., shortage of ventilators and splinting devices); 4) medical knowledge and care rendered by the hospital staff; 5) evacuation and escorting of the wounded; 6) management of patients with post-traumatic stress disorder; and 7) medical documentation. Their comments contributed valuable information on the quality of medical care and organization, and identified obstacles that otherwise would have been overlooked. The "smart casualties" were very cooperative and indicated that their participation in the drill contributed to their understanding of disaster situations in hospitals. CONCLUSION: Integrating physicians among the simulated casualties in a hospital disaster drill may contribute to achieving the objectives of hospital disaster drills and add to disaster management education of the simulated casualty physicians.- - - - - - - - - - ranking = 4keywords = physician (Clic here for more details about this article) |
7/130. A new hazard for windsurfers: needlefish impalement.Marine-related injuries and envenomations are common to the coastal physician. Needlefish injuries, which occur almost exclusively in the Indo-Pacific region, have not previously been reported along the Atlantic seaboard. This case report describes a penetrating injury to the lower extremity from a needlefish. Treatment is guided by general resuscitative procedures as well as antibiotic therapy directed against infections unique to the marine environment.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
8/130. Cardiovascular toxicity after ingestion of "herbal ecstacy"."Herbal Ecstacy" (sic) is an alternative drug of abuse usually containing both ephedrine and caffeine. Our literature search did not reveal any other reported cases of cardiovascular toxicity related to herbal "drugs of abuse." A case of cardiovascular toxicity following the ingestion of herbal ecstacy is presented. A 21-year-old male presented to the emergency department with an initial blood pressure of 220/110 mmHg and ventricular dysrhythmias after ingesting four capsules of herbal ecstacy. He was treated with lidocaine and sodium nitroprusside, and his symptoms resolved in 9 h. The pathophysiology and clinical course of ephedrine toxicity are discussed. Emergency physicians should consider ephedrine preparations in the differential diagnosis of patients presenting with a sympathomimetic toxidrome. Drugs of abuse containing "herbal" products can produce serious morbidity and mortality.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
9/130. Neurogenic pulmonary oedema after generalized epileptic seizure.The diagnosis 'tonic clonic seizure' is frequently established by emergency physicians on scene. In patients with epilepsy mortality due to accidents, asphyxia, cardiac arrhythmias or postictal neurogenic pulmonary oedema (NPO) is twice as high as in the general population. We report a case of acute pulmonary oedema after a tonic clonic seizure. Following this event, the patient developed respiratory insufficiency and evidence of pulmonary oedema not associated with the classic aetiologies of congestive heart failure, aspiration or toxic exposure. The patient survived the incident after aggressive prehospital treatment, long-term intensive care and subsequent rehabilitation. A systematic case analysis and an introduction to the pathophysiology of NPO are presented. We recommend a positive approach to the management of NPO consisting primarily of interventions to stabilize vital functions, decrease intracranial pressure and normalize vegetative dysregulation. Emergency physicians need to consider the possibility of NPO in all cases of pulmonary oedema of unknown origin.- - - - - - - - - - ranking = 2keywords = physician (Clic here for more details about this article) |
10/130. hemiplegia hypoglycaemia syndrome.We report the case of a 83-year-old man who presented to the emergency department with hypoglycaemia resembling a cerebrovascular accident. Hypoglycaemic hemiparesis is an under-recognized manifestation of hypoglycaemia. If not recognized and treated promptly, hypoglycaemia may cause irreversible central nervous system injury; it rarely results in death. It is imperative that emergency physicians consider hypoglycaemia in all patients with coma in spite of focal neurological deficit even when the findings seem to be explained initially by other aetiologies.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
