Abdominal pain with rigidity secondary to the anti-emetic drug metoclopramide.

We report a case of abdominal pain with rigidity, mimicking an acute abdomen, caused by metoclopramide, a common anti-emetic drug. Extrapyramidal symptoms are commonly reported side-effects of this medication. They generally include involuntary movements of limbs, torticollis, oculogyric crisis, rhythmic protrusion of tongue, trismus, or dystonic reactions resembling tetanus, etc. Abdominal rigidity due to this medication, resembling an acute abdomen, has not been reported previously. This case report illustrates the importance of considering medication side-effects when evaluating a patient with abdominal pain and rigidity.

Injury prevention and other international public health initiatives.

Injuries, whether caused by unintentional or intentional events, area significant public health problem. The burden of injury is greatest in low-and middle-income countries and among individuals of low socioeconomic status living in high-income countries. Most of these injuries are prevent-able. Emergency physicians can play an important role in reducing the global burden of injuries by providing expert care and by identifying, implementing, and evaluating population-based countermeasures to prevent and control injuries. The strategy used in a particular country depends in large part on the nature of the local problem, the concerns of the population, the availability of resources, and competing demands. Even simple countermeasures may have a big impact in reducing the global burden of death and disability due to injury.

Non-traumatic aortic emergencies--experience from a tertiary care centre in Karachi, Pakistan.

OBJECTIVE: To review the incidence, clinical presentation and outcome of Non traumatic Aortic emergencies in a tertiary care hospital and its evaluation in the Emergency department (ED). METHODS: We conducted a retrospective review of cases presented to the ED at Aga Khan University Hospital during 15 year period (1988 - 2002) who had final diagnosis of Aortic Dissection or Ruptured Aortic Aneurysm. Patients without confirmatory investigations were excluded. We aimed at looking for the incidence, clinical presentation, evaluation in the ED and final outcome. RESULTS: Of the 12 cases, 7 had aortic dissection while the remaining 5 had ruptured aortic aneurysm. For Aortic dissection, mean age of presentation was 53 years with male predominance. Most of these patients had chest pain. Most common comorbid condition was hypertension. Pulse deficit was found in 2 cases, murmur in 4 cases, and focal neurologic deficit in 2 cases. Electrocardiogram revealed ischemic changes in 3 cases. Widened mediastinum on chest x-ray was present in all cases. The only initial misdiagnosis was cardiac ischemia. One patient survived to discharge. For patients presenting with ruptured aortic aneurysm, mean age of presentation was 52 yrs with a male predominance. The associated comorbid condition was hypertension. Almost all patients presented classically with abdominal pain, hypotension and palpable mass. No patient survived to discharge. CONCLUSION: Aortic emergencies although rare, are associated with significant mortality. High index of suspicion and prompt recognition by the emergency physician is of key importance.

Confronting the ethical challenges to informed consent in emergency medicine research.

The Society for Academic Emergency Medicine believes that protection of human subjects is vital in emergency medicine research and that, whenever feasible, informed consent is at the heart of that protection. At the same time, the emergency setting presents unique barriers to informed consent both because of the time frame in which the research is performed and because patients in the emergency department are a vulnerable population. This report reviews the concept of informed consent, empirical data on patients' cognitive abilities during an emergency, the federal rules allowing exemption from consent under certain circumstances, issues surrounding consent forms, and the new Health Insurance Portability and Accountability Act regulations as they relate to research. The authors conclude that, in many circumstances, informed consent is possible if the researcher is diligent and takes time to adequately explain the study to the potential subject. In cases in which it is possible to obtain consent, precautions must be taken to ensure that subjects have decision-making capacity and are offered time to have their questions answered and their needs met. Sometimes resuscitation and other emergency medicine research must be conducted without the ability to obtain consent. In these cases, special protections of subjects under the exception from consent guidelines must be followed. Protection of research subjects is the responsibility of every researcher in emergency medicine.

Ethics seminars: the ethical debate on practicing procedures on the newly dead.

Emergency medicine and its academic teaching programs face an ethical dilemma surrounding the question of practicing procedures on the newly dead. For many years, procedures have been practiced on the newly dead, but few institutions have had policies addressing the practice. This article considers the ethical arguments both for and against practicing procedures on the newly dead without consent, reviews the empirical studies on the subject, and presents the positions of other professional societies, before concluding with the position of the Society for Academic Emergency Medicine (SAEM). SAEM strongly encourages all emergency medicine training programs to develop a policy and make that policy available to the institution, educators, trainees, and the public. The practice should not occur behind closed doors or on an ad hoc basis without clearly articulated guidelines. With improvements in technology, including patient simulation and virtual reality, the need for the practice may decrease, but there is no current evidence that is compelling regarding the best methods of teaching procedural skills. Given the importance of protecting trust in the profession of medicine and the existing evidence that the public would expect that consent be obtained, SAEM recommends that families be asked for consent prior to practicing procedures on the newly dead.

Emergency medical care in developing countries: is it worthwhile?

Prevention is a core value of any health system. Nonetheless, many health problems will continue to occur despite preventive services. A significant burden of diseases in developing countries is caused by time-sensitive illnesses and injuries, such as severe infections, hypoxia caused by respiratory infections, dehydration caused by diarrhoea, intentional and unintentional injuries, postpartum bleeding, and acute myocardial infarction. The provision of timely treatment during life-threatening emergencies is not a priority for many health systems in developing countries. This paper reviews evidence indicating the need to develop and/or strengthen emergency medical care systems in these countries. An argument is made for the role of emergency medical care in improving the health of populations and meeting expectations for access to emergency care. We consider emergency medical care in the community, during transportation, and at first-contact and regional referral facilities. Obstacles to developing effective emergency medical care include a lack of structural models, inappropriate training foci, concerns about cost, and sustainability in the face of a high demand for services. A basic but effective level of emergency medical care responds to perceived and actual community needs and improves the health of populations.
