Review
[Retropleural paraspinal approach in the treatment of anterolateral thoracic spinal diseases].
The personal experience in the treatment of the spinal and paraspinal thoracic pathology using the paraspinal retropleural approach is presented. A total of 18 patients with neoplastic, traumatic and discal lesions were operated on. Improvement of neurological disturbances and pain was noted in all patients. ⋯ The paraspinal retropleural approach is compared with the anterior transthoracic approach. The advantages of the paraspinal retropleural approach are: low rate of complications; allows a very wide decompression of the neurological elements as well as an anterior and/or posterior stabilization of the spine by a single approach; and it can be easily tailored for each lesion. These advantages are enhanced in the management of lesions located in the upper thoracic or thoracocervical levels.

Arachnoid cysts account for only 1% of all intracranial space-occupying lesions. In adults suprasellar cysts represent 9% of all the arachnoid cysts while in pediatric population this percentage reaches 15%. In spite of being a problem relatively common in daily neurosurgical practice there are still a number of questions to be solved concerning pathogenesis and evolution, natural history and treatment. ⋯ Preoperative symptoms improved in all the patients and five out of seven remain shunt free. One patient maintains a cystoperitoneal shunt and another one, previously shunted, remains shunt dependent. The clinical presentation and postoperative evolution are commented with discussion on the alternative therapeutic options from the endoscopic point of view.

Review Multicenter Study
[Minor head injury management in Spain: a multicenter national survey].
Despite of the high incidence of minor head injury, there is still controversy and disparity of criteria regarding its management. The lack of consensual protocols and clinical guidelines can lead to deficiencies in the attention to these patients and to inadequate use of resources. The objective of this study has been to describe the present situation of the management of this entity in the neurosurgical departments of the Spanish public hospitals, and to compare it with other European countries. ⋯ This study shows the inter-hospital variability of minor head injury management in Spain. Clinical guidelines are considered as positive and necessary. Although the Spanish situation is similar to that in other European countries, following the tendency toward a broader cranial CT utilisation, would improve diagnosis profitability and economical efficiency. The results of this study may contribute to the creation of consensual protocols and clinical guidelines in our country that help in daily practice decision-making optimising assistance quality.

Review
[The use of moderate hypothermia in the treatment of patients with severe craniocerebral trauma].
Traumatic brain injury initiates several metabolic processes that can increase the primary injury. It is well established that in severe head injuries, posttraumatic secondary insults, such as brain hypoxia, hypotension or anemia, exacerbate neuronal injury and lead to a poorer outcome. Experimental and clinical evidence suggests that moderate hypothermia (32-34 degrees C), may limit some of these deleterious secondary metabolic responses. ⋯ Further prospective controlled trials with clearly defined methodology are needed before this method is implemented in daily clinical practice. The most important task for the years to come may be to focus on refining this procedure, defining the optimal time of cooling and rewarming and to optimize the methods of rapidly inducing and maintaining low temperature. It is also essential to define the most appropriate method and velocity of the rewarming phase, in which many successfully controlled patients deteriorate and die.
