E. Latunde Odeku: the first African-American neurosurgeon trained in the United States.
The advances of the Civil Rights movement in the mid-20th century and the success of the first African-American neurosurgeons trained at the Montreal Neurological Institute have led to a number of African-Americans receiving neurosurgery training within the United States. Unfortunately, the details regarding the first African-American neurosurgeon trained in the United States, E. Latunde Odeku, have largely remained in obscurity. ⋯ C. S., enabled him to become the first African-American neurosurgeon trained in the United States. A truly global pioneer, his selfless service in America and Nigeria opened the door for people from each country to enhance the field of neurosurgery.

Randomized Controlled Trial Multicenter Study
Predictors of cerebral infarction in patients with aneurysmal subarachnoid hemorrhage.
Cerebral infarction would be expected to be associated with poor outcome after aneurysmal subarachnoid hemorrhage (SAH), although there are few data on which to base this assumption. The goals of this study were to determine the impact of cerebral infarction on outcome and to examine predictors of infarction in these patients. ⋯ Cerebral infarction was strongly associated with poor outcome after aneurysmal SAH. The most important potentially treatable factor associated with infarction was symptomatic vasospasm.

For this study, spheno-orbital meningiomas (SOMs) are defined as intraosseus meningiomas at the base of the anterior and middle cranial fossa, involving the sphenoid wing and orbit associated with a carpet-like, soft tissue component. We describe a surgical series of 63 SOMs, including surgical technique, complications, and recurrences. ⋯ Complete surgical resection of SOMs is frequently impossible because the involvement of delicate structures of the orbital cone is common. Although some persisting neurological deficits are possible, proptosis and other visual deficits are often relieved. Two-thirds of tumor rests remained stable during the follow-up period. Consequently, the surgical aim should be the relief of leading symptoms rather than radical resection.

Comparative Study
Comparison of two techniques to postoperatively localize the electrode contacts used for subthalamic nucleus stimulation.
Cerebral ventriculography (Vg) and magnetic resonance imaging (MRI) scanning are routine procedures to determine the implanted electrode placement into the subthalamic nucleus (STN) and are used in several centers that provide deep brain stimulation for Parkinson's disease patients. However, because of image distortion, MRI scan accuracy in determining electrode placement is still matter of debate. The objectives of this study were to verify the expected localization of the electrode contacts within the STN and to compare the stereotactic coordinates of these contacts determined intraoperatively by Vg with those calculated postoperatively by MRI scans. To our knowledge, this is the first study attempting to compare the "gold standard" of stereotactic accuracy (Vg) with the anatomic resolution provided by MRI scans. ⋯ If we assume that Vg is an imaging gold standard, our results suggest that postoperative MRI scanning may induce a slight image translation compared with Vg. However, MRI scans allowed localization of most of the contacts within the STN.
