Case Reports[Radiological and surgical characteristics of a case of recurring spinal hydatidosis].
Hydatidosis is an illness that is still to be found in our setting. The lungs and liver are the organs most frequently involved and it rarely extends to bones. Involvement of the spine is infrequent, but it can give rise to a high degree of disability and may recur despite apparently complete excision. Here we report a case of recurring spinal hydatidosis with radiological and surgical particularities. ⋯ Spinal hydatidosis is a rare condition that, in spite of correct surgical and medical treatment, often recurs. Magnetic resonance scans show characteristic 'honeycomb' images, which are sometimes large and have their origins in the body of the vertebra. Although successive surgical interventions can become increasingly more difficult because of old instrumentation or the conservation of compromised vertebral bodies, aggressive excision is indicated while the patient still has useful neurological functioning.

[Changes in verbal and nonverbal memory associated with bilateral hippocampal electrode implantation for epilepsy surgery].
An appropriate localization of ictal onset zone in refractory temporal lobe epilepsy favors an adequate outcome associated with surgical treatment. When video-electroencephalogram (video-EEG) and magnetic resonance imaging do not provide accurate data to locate ictal onset zone, the use of subdural or deep intracranial electrodes is indicated. Hippocampal electrode placement could generate functional changes in an unaffected hippocampus. ⋯ Based on the preservation of verbal and nonverbal memory after depth electrode placement, invasive recordings of the hippocampus seem to be safe.

[Primary stabbing headache: clinical characteristics and response to treatment in a series of 67 patients].
Primary stabbing headache (PSH) is defined by the presence of short stabbing pains in the first branch of the trigeminal nerve. According to population-based studies, it is very prevalent, but most cases present stabbing pains with low frequencies and intensities that do not lead the patient to seek medical attention. ⋯ Age at onset: 34.5 ± 16.7 years. Forty-nine cases (73.1%) were associated to another headache, above all migraine. Stabbing pains were often bilateral; 38 (56.7%) patients suffered more than one a day and 11 (16.4%) had more than 10 per day. They lasted less than five seconds in 48 patients (71.6%) and more than 10 seconds in 11 of them (16.4%), with an intensity of 6.8 ± 1.5. The age of onset of PSH was higher if it was the only type of headache than if it was accompanied by others. Twenty-six (38.8%) patients required preventive treatment for the associated headache and 16 (23.8%) took indomethacin, with a similar response in the two groups (73 versus 75%). CONCLUSIONS; PSH is not infrequent in headache clinics, but its phenotype differs from that reported in population-based studies. The characteristics of PSH vary depending on whether it is the only headache or is associated with others. Preventive treatment is often required and patients respond well to it.

Review[Treatment of spasticity in multiple sclerosis: new perspectives regarding the use of cannabinoids].
Spasticity remains a prevalent symptom in multiple sclerosis, with a significant associated disability and quality of life impairment. A significant improvement in therapy aimed at reducing multiple sclerosis relapses and modifying its course has been achieved in recent years. Both general and specific traditional treatments have, however, major limitations. ⋯ Randomized, placebo-controlled trials, as well as longer-term open-label extensions, have shown a clear-cut efficacy to reduce spasticity and their associated symptoms in those patients refractory to other therapies, with a good tolerability/safety profile. No tolerance, abuse or addictive issues have been found. New studies will be needed to find out potential new cannabinoid-related therapies.

Historical Article[Epilepsy in literature, cinema and television].
Literature, cinema and television have often portrayed stereotypical images of people that have epilepsy and have helped foster false beliefs about the disease. ⋯ Literature, cinema and television have often dealt with the subject of epilepsy, sometimes realistically, but in many cases they have only helped to perpetuate false beliefs about this disease.
