ACCIDENTAL VACCINIA

Accidental Infection of Laboratory Worker with Vaccinia

We report the accidental needlestick inoculation of a laboratory worker with vaccinia virus. Although the patient had previously been vaccinated against smallpox, severe lesions appeared on the fingers. Western blot and polymerase chain reaction-restriction fragment length polymorphism were used to analyze the virus recovered from the lesions. The vaccinia virus-specific immunoglobulin G levels...

Accidental Algorithms

We provide evidence for the proposition that the computational complexity of individual problems, and of whole complexity classes, hinge on the existence of certain solvable polynomial systems that are unlikely to be encountered other than by systematic explorations for them. We consider a minimalist version of Cook’s 3CNF problem, namely that of monotone planar 3CNF formulae where each variabl...

Accidental poisoning.

Accidental Hypothermia

The “reanimations” of profoundly cold victims in prolonged cardiac arrest and the emergence of therapeutic hypothermia after cardiac arrest help explain the contemporary allure of hypothermia. A 29-year-old Norwegian physician was successfully resuscitated from accidental hypothermia at 13.7° C after a 9-hour resuscitation. This included cardiopulmonary resuscitation initiated at the scene and ...

Accidental hypothermia.

Accidental hypothermia is an acute medical emergency with a high mortality rate. Physiologic derangements include hypoxemia, hypotension, acidosis, and arrhythmias. Management consists of careful monitoring rewarming, vigorous supportive care, and treatment of underlying and complicating disorders. Active core rewarming is recommended for hypothermia with associated cardiovascular insufficiency...
