The use of "stand-alone" contrast myelography (i.e., without computed tomography) has a proven track record in developing nations where few patients have access to magnetic resonance imaging, whether on the basis of prohibitive cost or the absence of such a modality altogether. To substantiate the author's 12-year experience with more than 300 myelograms performed in 16 different countries (plus some 1500 studies during 30 years of practice in the United States), a prospective pilot study was undertaken over 1 month in a community-based neurosurgical setting in western Kenya. Forty patients underwent cervical or lumbar myelography at Tenwek Hospital under the auspices of the Neurosurgery Training Program for East, Central, and South Africa (NSTP-ECSA) following failure of conservative measures to treat spine-related pathology. ⋯ There were no significant complications from the procedures, and no false-positive studies, with virtually all patients returning to normal activity and/or gainful employment within 3 weeks of their surgery. Myelography as a stand-alone diagnostic procedure is a sensitive, specific, and cost-effective means of diagnosing symptomatic degenerative spine disorders. Accordingly, its use should be encouraged at every NSTP-ECSA training site to address such ubiquitous pathology.

The significance of medial and lateral opticocarotid recesses and the planum sphenoidale region in skull base pathologies for the transsphenoidal-transplanum approach were evaluated. ⋯ The lateral opticocarotid recess is a reliable and persistent indicator for extended transsphenoidal surgery. To approach the opticocarotid region near the internal carotid artery and optic nerve, a careful dissection is needed to minimize surgical injuries to the optic nerve and carotid artery. Other factors determining a reliable bone resection are the anteroposterior length of the planum sphenoidale and the distance and width of the angle between optic nerves. Attention should be given to individual anatomic variations of the region when planning and performing transsphenoidal-transplanum surgery.

Historical Article
The Foundation for International Education in Neurological Surgery.
The Foundation for International Education in Neurological Surgery (FIENS) was established in 1969 for the purpose of promoting neurosurgical education and patient care in the developing world. Ghana, the first African site, was adopted in 1989. In 2005 a neurosurgical training program was developed for Ethiopia, Kenya, Tanzania, and Uganda in East Africa and the College of Surgeons of Central, East, and Southern Africa (COSECSA) approved the curriculum.

Although acute cocaine use has been correlated with aneurysmal subarachnoid hemorrhage, its effect on vasospasm and outcome is controversial. We investigated the effect of acute cocaine use on response to vasospasm treatment and neurologic outcome in patients with aneurysmal subarachnoid hemorrhage. ⋯ There is no significant difference in incidence of symptomatic vasospasm or neurologic outcome between cocaine users and nonusers. The severity of the vasospasm and the response to treatment, as indicated by the number of vasospasm interventions, did not differ between the two groups.

Hydrocephalus, a disease frequently associated with poverty, becomes even more challenging to treat in developing regions because of lack of neurosurgical manpower, inadequately equipped public health care facilities, meager resource allocations, high rates of neonatal infection, difficulty of accessibility to hospitals able to treat hydrocephalus, and high complication rates in patients who are able to access and receive shunting procedures. Definitive treatment of hydrocephalus that avoids shunting procedures and long-term shunt dependence is a safer option. In environments such as Sub-Saharan Africa (and, indeed, in other similar resource-challenged regions), neuroendoscopic ventriculostomy (NEV), in appropriately selected patients can overcome the problems associated with shunting, including long-term shunt dependence. ⋯ Using a single portable neuroendoscopy equipment system and a versatile free-hand, single operator neuroendoscope, an easily mobile outreach model has been successfully used to perform 187 procedures in 19 hospital sites around six countries and on two continents. Neuroendoscopy is not just a priority surgical tool for East Africa; it represents a best practices philosophy of what is possible within a highly sophisticated surgical speciality like neurosurgery in developing countries. It offers an opportunity to highlight the importance of tertiary care specialties like neurosurgery in this region, to develop closer relationships between African neurosurgeons and to convince medical students, general residents, and nurses that "world-class neurosurgery" can be possible in a developing region.
