Review[Biomedical publications in Spain on debate (II): the on-going 'revolutions' and their application to neurological journals].
To debate about the application of on-going 'revolutions' in medical knowledge to Spanish neurological journals in the 21st century. This article reviews the current status of five revolutions in the field of health sciences, in general, and in neurological sciences, in particular: 1) the knowledge revolution: to translate the scientific investigation to the patient, with knowledge needs-driven research agenda with founder commissioning research to answer questions posed by clinicians, managers and patients, and systematic and critical appraisal reviews as the creator of quality improved knowledge; 2) the evidence based medicine revolution: the pyramid information of '4S', with systems (guidelines and computerized decision support systems), synopses (secondary journals), syntheses (systematic reviews and meta-analysis) and studies (original studies published in journals); 3) the web revolution: the possibility of dissemination of biomedical documentation by means of the Internet network are producing changes in the traditional way of conceiving scientific publication; the Internet represents a great advantage for investigation and also for clinical practice, since it permits free, universal access to databases and the interchange of texts, images and videos; 4) the open access revolution: to take full control over all operations related to the process of publish (to create, publish, communicate, distribute, reproduce and transform) with no need of any intermediaries, and to transform fundamental aspects concerning the circulation of knowledge, its use and availability; and 5) the librarian revolution: the project of a Virtual Health Library in Spain as a tool to access and disseminate scientific and technical knowledge on health through the Internet.

Case Reports[Cerebral gas embolism secondary to withdrawal of a central venous line].
To report a case of cerebral gas embolism secondary to the withdrawal of a central venous line in a patient who had recently undergone abdominal surgery. ⋯ Cerebral gas embolism can be diagnosed using a CT scan of the head if it is performed immediately after the entrance of air into the bloodstream inside the brain. In later phases, findings are unspecific and difficult to distinguish from ischaemic infarction or from diffuse leukoencephalopathy. Treatment is based on supportive measures and, in some cases, hyperbaric oxygen, although their true effectiveness is a controversial issue. Cerebral gas embolism is a potentially fatal and avoidable complication in patients with a central venous line or other iatrogenic procedures that can allow air to enter the arterial or venous circulatory systems.

Review[Biomedical publications in Spain on debate (I): state of neurological journals].
Bibliometric studies belong to the so-called 'social studies of science', and science policy constitutes one of its main applied fields, providing objective and useful tools for evaluating the results of scientific activity. Neurological sciences are very important in the bibliometric map of Spain about biomedicine and health sciences, from a quantitative (second thematic area in productivity, only after biology-biochemical) and a qualitative (high health costs and morbimortality) point of view. ⋯ The Acuerdo de Buenos Aires is an initiative to promote scientific neurological papers of high quality in Spanish. The current status of neurological journals in the bibliometric context of our country is good and open to the advantages of electronic and free access.
