Comparative Study
Novel animal glioma models that separately exhibit two different invasive and angiogenic phenotypes of human glioblastomas.
Invasive behaviors of malignant gliomas are fundamental traits and major reasons for treatment failure. Delineation of invasive growth is important in establishing treatment for gliomas and experimental neuro-oncology could benefit from an invasive glioma model. In this study, we established two new cell line-based animal models of invasive glioma. ⋯ These animal models histologically recapitulated two invasive and angiogenic phenotypes, namely angiogenesis-dependent and angiogenesis-independent invasion, also observed in human glioblastoma. These cell lines provided a reproducible in vitro and in vivo system to analyze the mechanisms of invasion and angiogenesis in glioma progression.

Review Case Reports
Early multimodality treatment of intracranial abscesses.
The treatment of brain abscesses remains one of the success stories of contemporary neurosurgery; what began as a nearly uniformly fatal disease at the turn of the 20th century has become a largely curable ailment through the use of operative and pharmaceutical intervention. ⋯ Cushing employed a variety of operative drainage techniques for intracranial abscesses and implemented an early antibacterial agent to provide adjuvant treatment in one patient. Although these cases demonstrate a 50% mortality rate, they provide insight into the challenges faced by neurosurgeons treating intracranial abscesses at the turn of the 20th century.

Comparative Study
A population-based study of inpatient outcomes after operative management of nontraumatic intracerebral hemorrhage in the United States.
In the United States, data on patient outcomes after operative management of nontraumatic intracerebral hemorrhage (ICH) have been largely derived from tertiary care academic institutions. Given that outcomes of patients treated at these specialized centers may differ from those treated at community hospitals, our aim was to report patient outcomes on a population-based, national level. ⋯ Patients with intracerebral hemorrhage who undergo craniotomy or craniectomy have a high morbidity and mortality. Male gender, preoperative comorbidities, complications, and low hospital volume were associated with an increased risk of in-hospital mortality.

To analyze the impact of factors known after admission on mortality attributable to aneurysmal subarachnoid hemorrhage (SAH) resulting from saccular intracranial aneurysm (IA). ⋯ Sequelae of aneurysmal SAH were the leading cause of death for 12 months. Mortality analysis of this period displayed three phases with distinct independent risk factors. These data support the creation of prognosticators for prediction on admission of the everyday individual risk of death until 12 months after aneurysmal SAH.
