Extent of resection and survival in patients with glioblastoma multiforme: Systematic review and meta-analysis.

Background: Glioblastoma multiforme (GBM) owes an ominous prognosis: its mean overall survival is 14 months. The extent of surgical resection (ESR) highlights among factors in which an association has been found to a somewhat better prognosis. However, the association between greater ESR and prolonged overall (OS) survival is not a constant finding nor a proven cause-and-effect phenomenon.

Early Report on the Impact of COVID-19 Outbreak in Neurosurgical Practice Among Members of the Latin American Federation of Neurosurgical Societies.

Background: The COVID-19 pandemic has caused severe economic consequences by local governmental measures to contain the outbreak. We provide insight on the impact that health care restriction has made on neurosurgical activity in Latin Iberoamerica.

Methods: We performed an internet-based survey among presidents and members of the societies of the Latin American Federation of Neurosurgical Societies (FLANC).

Prevalence of Incidental Clinoid Segment Saccular Aneurysms.

Introduction: Clinoid segment aneurysms are cerebral vascular lesions recently described in the neurosurgical literature. They arise from the clinoid segment of the internal carotid artery, which is the segment limited rostrally by the dural carotid ring and caudally, by the carotid-oculomotor membrane. Even although clinoid segment aneurysms represent a common incidental finding in magnetic resonance studies, its prevalence has not been yet reported.

[Traumatic occipitocervical and atlantoaxial dislocation with clivus fracture in a child. Case report].

Background: Cranieovertebral junction lesions in the paediatric population are associated with a low survival rate, which has declined in recent years. Neurological disability is a major concern due to the high economical cost it represents. Paediatric patients are more susceptible to this lesion because of hyperextension capacity, flat articulation, and increased ligamentous laxity.

Pituitary tumor surgery: review of 3004 cases.

Objective: To report the efficacy, safety, and outcomes through time of the biggest series to our knowledge of pituitary surgery using transcranial, transsphenoidal, and endoscopic techniques.

Methods: An observational, retrospective, and descriptive review was performed of 3004 patients surgically treated by the senior author from 1973 to June 2011 in Mexico City. A sublabial approach was used in 3000 patients, and a transnasal approach was used in the remaining 4 patients.

Mexican hospitals.

In order to understand current medical and hospital care in Mexico, we need to know first their past and then compare that past to their present situation. We can attempt to glimpse into what their future should be. The evolution of Mexican health services from the time of the Spanish Conquest until the the post-revolutionary period involved the creation of hospitals for both the poor and the rich.

Cerebral salt wasting syndrome in patients with aneurysmal subarachnoid hemorrhage.

Objective: Hydroelectrolytic disturbances are part of the complications of subarachnoid hemorrhage. Cerebral salt wasting syndrome (CSWS) must be considered when hyponatremia is associated with a decrease in circulating volume. We performed this study to determine the clinical characteristics and management paradigm of patients with serum sodium concentration abnormalities and aneurysmatic subarachnoid hemorrhage.
