Historical Article
Neurosurgery in Tanzania: a discussion of culture, socioeconomics, and humanitarians.
To elucidate the progress of neurosurgical practices in Tanzania, taking into account humanitarian, socioeconomic, and geographic influences. ⋯ Neurosurgery in Tanzania and Africa more generally has a long history; however, it was not until more recent efforts of certain local pioneers and educational advisors abroad that modernization occurred. The progress of the past 50 years is substantial and with continued efforts advances will continue to be made.

Comparative Study
Cognitive changes in patients with aneurysmal subarachnoid hemorrhage before and early posttreatment: differences between surgical and endovascular.
The main purpose of occluding a ruptured aneurysm is preventing rebleeding, which may be fatal. Microsurgical or endovascular treatments are the main approaches adopted to prevent new bleeding. Among patients presenting with aneurysmal subarachnoid hemorrhage, about 50% had permanent injuries. Cognitive changes are one of the main morbidities from that illness. The type of treatment for the aneurysm (clipping or coil embolization) can also contribute to the genesis of those complications. ⋯ One hundred fifty-one patients were assessed, distributed as 122 surgical and 29 coil embolized. The performances in both groups did not differ in the initial assessment. However, endovascular treatment does not show additional cognitive impairment and had a better performance in language and verbal memory, compared with patients submitted to surgical treatment in an early postoperative period.

To highlight pertinent aspects of emergent endovascular management of carotid rupture, or carotid blowout syndrome (CBS), an emergent, life-threatening complication of head and neck cancer and its treatments. ⋯ The treatment of patients with terminal malignant disease and CBS should provide maximum relief and minimize the risks of repeat surgery, morbidity, and mortality. Endovascular management of CBS with deconstructive techniques achieves immediate hemostasis and definitive treatment. The risks of intraoperative mortality and recurrent hemorrhage are low.

Capillary hemangiomas are benign vascular lesions involving the skin and soft tissues that commonly occur at birth or an early age. Intracranial capillary hemangiomas are extremely rare; only 14 cases have been reported the literature. ⋯ Surgery is an option for symptomatic intracranial capillary hemangiomas. However, because partial removal is associated with a high recurrence rate, capillary hemangiomas that cannot be removed radically should be treated with radiotherapy, which offers the possibility of controlling lesion size and preventing tumor recurrence.

Craniofacial resection has been considered the gold standard in the management of malignancies involving the anterior skull base, where the goal of surgery is negative margins with minimal morbidity. In recent years, there has been growing enthusiasm for purely endoscopic techniques for craniofacial malignancies. Given recent advancements in open surgical approaches, there is a need to review the technique of open craniofacial resection in the modern surgical era. ⋯ Since its introduction more than 50 years ago, craniofacial resection has undergone several important technical advancements concurrent to the introduction of endoscopy. With these improvements, our results indicate good oncologic disease control with minimal morbidity for extensive malignancies invading the intracranial cavity. With improvements in both open and endoscopic techniques, there is a need to reassess outcomes to determine relative indications.
