Review Meta AnalysisEpidemiology of traumatic brain injury in Europe.
Traumatic brain injury (TBI) is a critical public health and socio-economic problem throughout the world, making epidemiological monitoring of incidence, prevalence and outcome of TBI necessary. We aimed to describe the epidemiology of traumatic brain injury in Europe and to evaluate the methodology of incidence studies. ⋯ Interpretation of published epidemiologic studies is confounded by differences in inclusion criteria and case ascertainment. Nevertheless, changes in epidemiological patterns are found: falls are now the most common cause of TBI, most notably in elderly patients. Improvement of the quality of standardised data collection for TBI is mandatory for reliable monitoring of epidemiological trends and to inform appropriate targeting of prevention campaigns.

Review Meta AnalysisIntracranial meningiomas and seizures: a review of the literature.
Seizures are a common manifestation of brain tumors, but literature on the incidence of seizures before and after surgery for meningiomas is limited, and principles for use of antiepileptic drugs (AEDs) are controversial. ⋯ Seizures are a common manifestation of meningiomas, but about 80 % patients with preoperative seizures can be seizure free after tumor removal. Prospective controlled AED trials specifically on meningioma patients are much needed.

ReviewVago-glossopharyngeal neuralgia: a literature review of neurosurgical experience.
Glossopharyngeal neuralgia (GPN), or better named vago-glossopharyngeal neuralgia (VGPN), is a rare disorder amounting to 1 % of the incidence of trigeminal neuralgia (TN). Pain is paroxysmal, of the electrical shooting type, and mainly provoked by stimulation of the pharynx or deep throat, especially during swallowing. Due to its rarity, VGPN is often misdiagnosed. ⋯ In patients with precarious general conditions, stereotactic radiosurgery may be considered. Also, thermo-rhizotomy at the pars nervosa of foramen jugularis or tractotomy-nucleotomy at brainstem may be alternatives, but these methods entail a significant risk of deficits. In this article, the authors reviewed the main literature series on neurosurgical treatments of this disease.

Review Historical ArticleThe evolution of brain surgery on awake patients.
In the early days of modern neurological surgery, the inconveniences and potential dangers of general anesthesia by chloroform and ether using the so-called "open-drop technique" led to the quest for alternative methods of anesthesia. Besides preventing the feared side effects, the introduction of regional anesthesia revealed another decisive advantage over general anesthesia in neurosurgery: While intraoperative direct cortical stimulation under general anesthesia could only delineate the motor area (by evocation of contralateral muscular contraction), now, the awake patients were able to report sensations elicited by this method. These properties advanced regional anesthesia to the regimen of choice for cranial surgeries in the first half of the 20th century. ⋯ Intraoperative mapping of brain functions using electrical stimulation in awake patients enables not only for increased tumor removal while preserving the functional status of the patients but also opens a window to cognitive neuroscience. Observations during such interventions and their correlation with both pre - and postoperative neuropsychological examinations and functional neuroimaging is progressively leading to new insights into the complex functional anatomy of the human brain. Furthermore, it broadens our knowledge on cerebral network reorganization in the presence of disease-with implications for all disciplines of clinical neuroscience.

Awake craniotomy is a valuable procedure since it allows brain mapping and live monitoring of eloquent brain functions. The advantage of minimizing resource utilization is also emphasized by some physicians in North America. Data on how well an awake craniotomy is tolerated by patients and how much stress it creates is available from different studies, but this topic has not consequently been summarized in a review of the available literature. Therefore, it is the purpose of this review to shed more light on the still controversially discussed aspect of an awake craniotomy. ⋯ For selected patients, an awake craniotomy presents the best possible way to reduce the risk of surgery related neurological deficits. However, benefits and burdens of this type of procedure should be carefully considered when planning an awake craniotomy and the decision should serve the interests of the patient.
