Biography Historical Article[Autopsy of a common error: the introduction of curare in Europe by W. Raleigh].
One of the most erroneous and repeated assertion in the history of pharmacology for anaesthetists is to say that "the curare was introduced in Europe by Sir Walter Raleigh under the name of ourari". On the contrary, the names to be reminded are: Lawrence Keymis for the first citation of the word ourari, José Gumilla for the word curare and the description of its effects, Charles-Marie de La Condamine for the import of the first known samples. The mistake was initiated by Alexander von Humboldt and developed by the physiologist Münter, a student of Johannes Müller, quoted by Claude Bernard. The repetition of this error was facilitated by the world diffusion of Claude Bernard's work.

Therapeutic hypothermia (less than 35 degrees C) is a promising strategy to improve neuroprotection after severe brain injury. Except in patients resuscitated from cardiac arrest, its effectiveness has not yet been demonstrated. ⋯ These hazards are associated with practical difficulties to induce and maintain targeted hypothermia and with rewarming management. An improvement in the techniques for achieving targeted hypothermia, more knowledge about side effects and further randomized clinical trials are needed before recommending the use of therapeutic hypothermia for patients with severe traumatic brain injury.

Diagnosis of postoperative myocardial infarction is often difficult, based on tools with a low sensitivity (clinical symptoms, EKG), or with a low specifity (old biomarkers, echocardiographic abnormalities) or inadequate for clinical practice (scintigraphy). Since 1995, clinicians may use more cardiospecific markers (troponin) allowing to modify strategy for postoperative myocardial infarction diagnosis. The aim of this review is to resume such an attitude.

Fever is a secondary brain injury and may worsen neurological prognosis of neurological intensive care unit (NICU) patients. In response to an immunological threat, fever associates various physiological reactions, including hyperthermia. Its definition may vary but the most commonly used threshold is 37.5 degrees C. ⋯ Whereas no causal link has been established between fever and unfavourable outcome, it seems reasonable to treat hyperthermia in patients suffering from brain injuries. In such patients, antipyretics have a moderate efficacy. In case of failure, they should be replaced by physical cooling techniques.
