Review Case Reports[Dissection of vertebral artery: report of a case and review of the literature].
Vertebral artery dissection seems to be a frequent cause of stroke in young adults. We report a 34 years old female that suffered a cardiac arrest while practicing aerobics, with complete recovery and four months later developed an acute Wallenberg's syndrome. Magnetic resonance imaging showed an infarction in the right posterolateral medulla oblongata and in the right cerebellar hemisphere. ⋯ A follow up angiography, performed six months later, showed an incomplete recanalization of the vessel. Vertebral artery dissection should be suspected in every patient with ischemic symptoms or signs related to the vertebrobasilar territory, specially in young or middle aged patients with a history of trauma. Magnetic resonance imaging and ultrasound-doppler examinations are the diagnostic test of choice.

A disaster is defined as a unseasonable event that provoke such an amount of victims that the health care capacity of the community is exceeded. The aim of this paper is to review the health attention during an emergency period, whose pre-hospital and hospital services are inherent to critical care medicine. The reduction in victim's morbidity and mortality depends on the opportuneness and efficacy of pre-hospital care. ⋯ At the hospitals an emergency team must elaborate, publish and periodically review emergency care plans and eventually coordinate actions with other community organizations. The diverse phases of the plan must be specified, including preparatives, alerting of involved services, victim care, and reestablishment of normal duties when the emergency situation ceases. As complement, the hospital must have security and evacuation plans to face own emergency situations such as fires, explosions and inundations.
