Catheter-related infection remains a cause of morbidity in the use of external ventricular drains (EVDs). The aim of this retrospective single-center study was to assess the rate and factors related to ventriculostomy infections in the setting of the published literature. ⋯ Catheter-related infection remains an important complication of EVD placement. Of factors evaluated, length of time of catheter placement has the most notable relationship to infection incidence, suggesting that early drain removal should be a goal whenever medically appropriate.

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.

Extradural spinal meningiomas are rare. Our understanding of purely extradural spinal meningiomas is incomplete because most reports rarely differentiate purely extradural meningiomas from extradural meningiomas with an intradural component. Occasionally, reports have described involvement of the adjacent nerve root, but there has never been a description of an extradural meningioma that actually infiltrates the nerve root. ⋯ Purely extradural meningiomas are rare, and our case is one of the first to describe a patient with an extradural meningioma that actually infiltrates the nerve root. Extradural spinal meningiomas are usually not adherent to the dura, but only appear to be adherent or invade (as in our patient) the adjacent nerve root. They are easily mistaken preoperatively and grossly intraoperatively for malignant metastatic tumors and can change the proposed surgical treatment. The long-term prognosis remains uncertain, but our patient's last follow-up suggests a favorable prognosis.

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.
