No es sólo una confrontación entre buenos y malos, entre quienes quieren proteger a los creadores y sus obras y quienes las roban, estereotipo que abunda en las campañas y en los discursos contrarios a lo que se ha denominadosin maticespiratería. Los actores involucrados han abordado el "problema" de la piratería desde enfoques no sólo erróneos, sino que extemporáneos. Y, de paso, los esfuerzos por derrotar lo que se denomina sin distinciones piratería arrastran, consigo, los derechos de los mismos creadores a crear -valga la redundancia-, así como de los ciudadanos a gozar de los bienes culturales.

The complications associated with intrathecal pump placement include persistent cerebrospinal fluid (CSF) leak, hygroma, meningitis, and granuloma formation. A severe persistent CSF leak may cause postdural puncture headache along with acute intracranial subdural hematoma, which can be potentially life threatening. Surgical exploration with dural repair is required to treat this severe complication when conservative treatments fail. We present a case report of severe persistent CSF leak after intrathecal pump revision that resulted in a subdural hematoma and postdural puncture headache. In this case, an epidural blood patch was performed using epidural catheter under fluoroscopic guidance to target the site of CSF leak and to avoid damaging the intrathecal catheter. This patient's headache was resolved and intrathecal catheter remained intact after this blood patch.

Use of neurophysiological monitoring has extended to neuroendovascular procedures, but evidence of its impact on clinical outcome in this arena is limited. To report the incidence of significant intraoperative somatosensory evoked potential (SSEP) changes during neuroendovascular surgery and to correlate SSEP changes with clinical outcomes. Patients who underwent neuroendovascular surgery at our institution between 2011 and 2013 were included in the analysis. Medical charts and imaging studies were reviewed retrospectively for sex, age, lesion type and size, clinical presentation, type of endovascular procedure, duration of SSEP change, reversibility of SSEP change, incidence of intraoperative complications and related mortalities, presence of new infarction within 72 hours of intervention, and discharge outcome. Of 873 consecutive patients, 52 (6%) had clinically significant intraoperative SSEP changes. Twenty-four patients (46%) had SSEP changes that were corrected, and 28 patients (54%) had changes that were not reversed before the end of surgery. Both decreased duration and reversal of SSEP changes were associated with a lower incidence of postoperative infarction and more favorable clinical outcome on discharge. The positive predictive value of an irreversible SSEP change for postoperative infarction in our study was 21%, and the negative predictive value was 83%. The approximate incidence of SSEP changes is 6% during neuroendovascular procedures. Rapid reversal of SSEP changes is associated with better outcomes. SSEP monitoring may be a valuable tool for preventing complications after neuroendovascular interventions.

Findings pertain to a broader research project being developed by a multidisciplinary team employing a non-usual research methodology in higher education (HE) research and students with disabilities: biographical-narrative methodology. The general aim is to analyse – by listening to the students themselves – barriers and support identified as affecting access, academic performance and overall perception of the HE experience. The present paper analyses lecturer-centred data to focus specifically on one of the objectives of our research project: the role that lecturers play in the inclusive education of students with disabilities. Unlike other international research, this article explores the barriers and support differentiating between five fields of knowledge: health sciences, experimental sciences, social sciences (law and educat...

A 51 years old man with numerous filiform warts located in an area of the beard extended to the maxillar region and the neck, of two years of evolution is presented. Previously he had aplied topical steroids. A combined

We investigated this question by analyzing the responses from single neurons, recorded in several cortical areas of parietal and frontal lobes, while trained monkeys reported the presence or absence of a mechanical vibration of varying amplitude applied to the skin of one fingertip. Here we show that the strength of the covariations between neuronal activity and perceptual judgments progressively increases across cortical areas as the activity is transmitted from the primary somatosensory cortex to the premotor areas of the frontal lobe. This finding suggests that the neuronal correlates of subjective sensory experience gradually build up across somatosensory areas of the parietal lobe and premotor cortices of the frontal lobe. detection | perception | psychophysics | somatosensory

However, by inducing an illusory perception of movement, Naito and colleagues show in this issue of Neuron that the illusory perception of movement is related to activation of primary motor cortex.

We attempt to disclose to what extent educational thinking gives priority to the training of the students in scientific concepts, laws and theories needed in further courses (propedeutic training) and how this thinking pays less attention to the so-called scientific literacy which is meant to be the main object of the teaching of science according to the designers of the curriculum. To achieve this, we carried out a multiple and convergent experimental design with a number of samples of teachers. We found a confirmation that in secondary education, the curricular emphasis of teachers focuses on the propedeutic training of students.
