Review Meta Analysis[Effectiveness of flunarizine in the prophylaxis of migraine: a meta-analytical review of the literature].
Migraine is a common and disabling health problem among young and middle aged adults. Flunarizine have been used as a prophylactic medication in its management for more than two decades. ⋯ Based on a small number of trials, flunarizine, at a daily dose of 10 mg lightly reduces the frequency of migraine attacks.

Review[Modern day psychosurgery: a new approach to neurosurgery in psychiatric disease].
To obtain an up to date review of the different possible surgical approaches in the management of certain psychiatric disorders that are refractory to conservative treatment (pharmacotherapy, psychotherapy, electroconvulsive therapy). ⋯ The most noteworthy progress in psychosurgery in recent years has been the combination of a more rigorous selection of patients and the higher degree of specificity with which treatment is performed on the brain structures involved in psychiatric disease. The most widely employed psychosurgical procedures at present are cingulotomy, anterior capsulotomy, subcaudate tractotomy, limbic leucotomy and postero medial hypothalamotomy, with favourable responses in about 35 70% of cases. The psychiatric diagnoses where the best results are to be found are obsessive compulsive disorder, chronic anxiety states and major depression. Current progress in neuroimaging techniques, increased neurophysiological knowledge and the revolutionary neuromodulation techniques, especially deep brain stimulation, offer an even more promising future for psychiatric neurosurgery.

Review[Applications of the determination of brain tissue oxygen pressure (PtiO2)].
We review the basic aspects concerning the technique of measurement of partial brain tissue oxygenation (PtiO2) monitoring, and its indications in neurological patients. ⋯ Monitoring the PtiO2 of focal brain tissue is a safe and reliable method for regulating cerebral oxygenation. PtiO2 monitoring has some advantages over other established methods such as near infra red spectroscopy and SjO2 monitoring: 1) recalibration is not necessary, and 2) once inserted, it allows valid and stable measurement lasting hours and even days.

In this review we study drug addiction from a neurobiological point of view, emphasizing the dopamine hypothesis. This is basic to explain how a genetic feature is related with an alteration of this neurotransmitter and can connect with environmental factors to develop the addiction problem. ⋯ Knowing the neurobiological mechanisms involved in addiction and its relation with dopamine and the reward system can help us understand that problem and aid the rational development of treatment

Review Case Reports[Unilateral isolated paralysis of the soft palate: a case report and a review of the literature].
Unilateral isolated paralysis of the soft palate is a rare clinical entity. ⋯ This is probably a case of acute cranial mononeuropathy with a viral aetiology
