Editorial Review Biography Historical ArticleWhat does Al-Qanun Fi Al-Tibb (the Canon of Medicine) say on head injuries?
A historical approach could help in the detection of some viewpoints that cannot be paid attention to or signified by a purely medical one. In this text, the important points of Ibn Sina's (Avicenna) treatise on head injuries have been introduced in light of neurosurgery. ⋯ Ibn Sina provided extremely systematic knowledge on head traumas along with both his observations and experiences and citations from the writings of the ancient physicians, Galen and Paul of Aegina. Regarding the treatment of skull fractures, Ibn Sina is a real successor of Galen and Paul of Aegina.

ReviewDendritic-cell- and peptide-based vaccination strategies for glioma.
Despite advances in radiation and chemotherapy along with surgical resectioning, the prognosis of patients with malignant glioma is poor. Therefore, the development of a new treatment modality is extremely important. There are increasing reports demonstrating that systemic immunotherapy using dendritic cells and peptide is capable of inducing an antiglioma response. ⋯ Dendritic cell- and peptide-based therapy of glioma seems to be safe and without major side effects. There are several types of glioma; so to achieve effective therapy, it may be necessary to evaluate the molecular genetic abnormalities in individual patient tumors and design novel immunotherapeutic strategies based on the pharmacogenomic findings. Here, in this review, recent advances in dendritic-cell- and peptide-based immunotherapy approaches for patients with gliomas are discussed.

To compare the image quality of a standard definition (SD) three-chip camera with a new high-definition (HD) three-chip camera. In five neurosurgical interventions, an SD three-chip camera and an HD three-chip camera were used with the same endoscopic equipment. Both cameras were used while performing one endoscopic third ventriculostomy, one endoscope-assisted microvascular decompression, one endoscope-assisted removal of a vestibular schwannoma, and two endonasal pituitary surgeries. ⋯ The progressive image processing of the HD camera provided a much clearer image than the interlaced image processing of the SD camera, especially with a modern flat panel screen. HD imaging provides a much better image quality compared to SD imaging. Therefore, we recommend use of HD cameras in neuroendoscopic procedures.

Review Case ReportsSymptomatic vertebral artery conflicts to the medulla oblongata and microsurgical treatment options: review of the literature.
Symptomatic vascular compression of the medulla oblongata causing brainstem dysfunction is extremely rare. Only a few case reports documenting the clinical condition of patients, diagnostic features and therapeutic options are available in literature. The Medline search revealed with the present cases a total of 9 reports on patients with symptomatic vertebral artery compression to the brainstem. ⋯ The history, diagnostic features, microsurgical treatment and outcome of these patients are described in detail. As a conclusion these cases demonstrated that careful examination can serve to determine the diagnosis even in the young population microsurgical treated successfully. In conclusion the present review tries to provide an overview of the existent data on the variety of clinical, radiological and surgical features in patients with symptomatic vascular brainstem compression.

Case ReportsDumbbell-shaped jugular foramen schwannomas: surgical management, outcome and complications on a series of 16 patients.
Schwannomas of the lower cranial nerves are very rare and the dumbbell-shaped ones are even rarer. The authors report their experience in managing such lesions, usually presenting either with intra- and/or extra-cranial extension through an enlarged jugular foramen. The juxtacondylar approach without sacrificing the labyrinth was used; clinical, radiological and complication features are discussed and analysed. ⋯ At a mean follow-up of 6.6 years (range 2-14 years), no radiological tumour recurrence was recorded amongst the patients having complete resection as well as no tumour progression in the group of near total removal. Jugular foramen schwannomas can be radically and safely resected with no additional neurological deficit if a careful pre-operative evaluation and the appropriate surgical approach is implemented. Finally, full cranial nerve functional recovery may be expected after complete resection.
