A giant, complex fronto-ethmoidal ivory osteoma: Surgical technique in a resource-limited practice
Date of publication: 31-Dec-2010
Background:Unlike small and medium size fronto-ethmoidal osteomas which are amenable to surgical excision through limited craniofacial openings, giant lesions require extensive and complex craniofacial dissection, and post lesionectomy reconstruction using an array of modern-day surgical adjuncts. This is a report of our surgical technique for the successful and esthetically fair operative resection of a giant fronto-ethmoidal osteoma in a difficult practice setting.
Stem cells for spinal cord regeneration: Current status
Date of publication: 25-Dec-2010
Background:Nearly 11,000 cases of spinal cord injury (SCI) are reported in the United States annually. Current management options give a median survival time of 38 years; however, no rehabilitative measures are available. Stem cells have been under constant research given their ability to differentiate into neural cell lines replacing non functional tissue. Efforts have been made to establish new synapses and provide a conducive environment, by grafting cells from autologous and fetal sources; including embryonic or adult stem cells, Schwann cells, genetically modified fibroblasts, bone stromal cells, and olfactory ensheathing cells and combinations/ variants thereof.
Retained transorbital foreign body with intracranial extension after pipe bomb explosion
Date of publication: 25-Dec-2010
BackgroundPenetrating brain injuries caused by explosions are survived in extremely rare cases only. However, potential casualties of such cases may be encountered by regular physicians even outside a war zone, e.g., due to an assault or terror blast. There is very limited literature to this end; therefore, we report the successful neurosurgical management of a penetrating head injury due to a pipe bomb explosion.
A pregnant female with a large intracranial mass: Reviewing the evidence to obtain management guidelines for intracranial meningiomas during pregnancy
Date of publication: 25-Dec-2010
Introduction:Non-obstetric surgery for intracranial meningioma is uncommon during pregnancy and poses significant risks to both the mother and the fetus. We present a case of a parturient that presented with acute mental status changes and we illustrate the decision making process that resulted in a best-possible outcome.
CT Ventriculography for diagnosis of occult ventricular cysticerci
Date of publication: 23-Dec-2010
Background:Neurocysticercosis is the most common parasitic infection of the central nervous system (CNS). Intraventricular lesions are seen in 7–20% of CNS cysticercosis. Intraventricular lesions can be missed by computed tomography (CT) and magnetic resonance imaging (MRI) as they are typically isodense/isointense to the cerebrospinal fluid. We present our experience with CT ventriculography to visualize occult cysts.
Treatment of ruptured intracranial dissecting aneurysms in Hong Kong
Date of publication: 22-Dec-2010
Background:Data suggests that hemorrhagic presentations occur in 20% of internal carotid artery dissections and 50% of vertebral artery dissections. A Finnish study has reported favorable outcomes in only 32% of patients.
Unusual manifestations of primary Glioblastoma Multiforme: A report of three cases
Date of publication: 22-Dec-2010
Background:Brain tumors, especially high-grade gliomas, can present with focal or generalized signs due to mass effect, parenchymal infiltration and destruction. In general, at the time of diagnosis, tumors could cause common neurological symptoms and major clinical signs depending on their localization. In rare instances, brain tumors colud be manifested with unusual symptoms.
A review of the management of posterior communicating artery aneurysms in the modern era
Date of publication: 22-Dec-2010
Background:Technical advancements have significantly improved surgical and endovascular treatment of cerebral aneurysms. In this paper, we review the literature with regard to treatment of one of the most common intra-cranial aneurysms encountered by neurosurgeons and interventional radiologists.
Comparative study between cortical bone graft versus bone dust for reconstruction of cranial burr holes
Date of publication: 22-Dec-2010
Background:As a consequence of the progressive evolution of neurosurgical techniques, there has been increasing concern with the esthetic aspects of burr holes. Therefore, the objective of this study was to compare the use of cortical bone graft and bone dust for correcting cranial deformities caused by neurosurgical trephines.
