The aim of this study is to describe six cases with spontaneous resorption of sequestrated intervertebral disc herniation observed using magnetic resonance imaging. In addition, the possible mechanisms, predictive factors of spontaneous disappearance of the sequestrated disc herniation, and the proper surgical timing were discussed and reviewed in literature. ⋯ We found that sequestrated disc herniation has potential for regression, which can be clearly demonstrated by magnetic resonance imaging, because of having higher water content, and therefore, may regress through both dehydration and inflammation-mediated resorption. We suggest conservative treatment in the initial course of the sequestrated type of disc herniation for at least 2 months before recommending surgical intervention unless severe neurologic deterioration takes place.

Increased intracranial pressure (ICP) that is refractory to medical measures and ventriculostomy placement after severe traumatic brain injury or aneurysmal rupture is associated with high mortality. In some recent reports, authors have described the use of lumbar cerebrospinal fluid drainage in these patients. We report the results of a prospective study involving the use of lumbar drainage in 15 patients with elevated ICP that was refractory to medical management and ventriculostomy placement. ⋯ This study shows the beneficial role of lumbar cerebrospinal fluid drainage as an effective and safe treatment modality for elevated ICP.

There are only three fully trained neurosurgeons to care for Tanzania's population of more than 41 million people. Madaktari was founded in 2006 to serve as a physician training partnership to establish more self-sufficient health care through education and training. Medical students play a valuable role in Madaktari as they are primarily responsible for collecting postneurosurgical outcome data on operations performed by Tanzanian physicians trained by our organization. ⋯ After working with Madaktari nearly half of the medical student volunteers have pursued or will be pursuing year-long funded global health research during their medical school careers. Madaktari is not only pioneering a path toward increased and more independent neurosurgical capabilities in Tanzania, but it is also helping foster increased interest and participation among U. S. medical students in global neurosurgery.

Percutaneous balloon rhizotomy for trigeminal neuralgia using three-dimensional fluoroscopy.
Percutaneous balloon rhizotomy is one of the standard techniques for the treatment of trigeminal neuralgia. However, there have been well-reported complications from cannulating the foramen ovale (FO). We describe a novel technique for cannulating the FO using 3-dimensional (3D) rotational fluoroscopy. ⋯ Three-dimensional rotational fluoroscopy allows real-time visual guidance to cannulate the FO and determine the optimal position of the inflated balloon. We believe that this is an important adjunct for treating trigeminal neuralgia via percutaneous techniques.
