ReviewConsequences of brain damage in the public debate regarding the end of life. The mediatic prism: A reflection of reality?
For the last 20 years or so, conflicts on life-support have become the object of widespread media coverage. By focusing public opinion on the alleged physicians' unreasonable obstinacy, these publicized cases impact social debates on life-support. By these, they justify claims for the legalization of assisted suicide, specifically the practice of termination of life by lethal injection. ⋯ As it turns out, the publicized filter does not reflect the true reality of cases involving unreasonable care. Specific procedures could aid in notifying the existence of such situations. The role of health care professionals (excluding physicians) appears to play an essential part in preventing these situations from happening.

Deciding to cease treatment in intensive care unit patients whose prognosis is hopeless allows programming the moment of death, and hence, post mortem transplantable organ donation. Such organ donations are more frequent in Anglo-Saxon countries. In the context of growing organ needs, they have significantly increased the number of organs that are available for transplant. ⋯ Supportive treatment cessation must be done according to previously established procedures. Medications that are compatible with organ transplantation must be listed. Finally, the needs of patient relatives must be met.

ReviewElectrical modulation of neuronal networks in brain-injured patients with disorders of consciousness: A systematic review.
Six clinical studies of chronic electrical modulation of deep brain circuits published between 1968 and 2010 have reported effects in 55 vegetative or minimally conscious patients. The rationale stimulation was to activate the cortex through the reticular-thalamic complex, comprising the tegmental ascending reticular activating system and its thalamic targets. The most frequent intended target was the central intralaminar zone and adjacent nuclei. ⋯ Other treatments that have offered some clinical benefit include drugs, repetitive magnetic transcranial stimulation, median nerve stimulation, stimulation of dorsal column of the upper cervical spinal cord, and stimulation of the fronto-parietal cortex. No one treatment has emerged as a gold standard for practice, which is why clinical trials are still on-going. Further clinical studies are needed to decipher the altered dynamics of neuronal network circuits in patients suffering from severe disorders of consciousness as a step towards novel therapeutic strategies.

Transcranial magnetic stimulations (TMS) have been used for many years as a diagnostic tool to explore changes in cortical excitability, and more recently as a tool for therapeutic neuromodulation. We are interested in their applications following brain injury: stroke, traumatic and anoxic brain injury. ⋯ TMS is a useful non-invasive brain stimulation tool to diagnose the effects of brain injury, to study the mechanisms of recovery and a non-invasive neuromodulation promising tool to influence the post-lesional recovery.

In face of any severe stroke, the questions for health professionals in charge of the patient are: will the handicap be acceptable for the patient? But can we predict an acceptable handicap for the patient? For his family? When we know that the cognitive disorders, consequences of severe stroke often modify, in a major way, the behaviour of these patients? Given these difficulties for estimate vital and functional prognosis and even more the quality of life of patients with severe stroke, collective reflexions between physicians and nurses are essential, reflexions taking into account preferences and values of patients. Use of resuscitation resources for severe stroke patients implies to offer them the best rehabilitation. So, questions about health pathways for severe stroke are essential: which structures for these patients, which technologies, which medical, medico-social and social supports, which human accompaniment the society can propose to the patients and to their family, so that they have an acceptable quality of life.
