Morbidity profile following aggressive resection of parietal lobe gliomas.
The impact of parietal lobe gliomas is typically studied in the context of parietal lobe syndromes. However, critical language pathways traverse the parietal lobe and are susceptible during tumor resection. The authors of this study reviewed their experience with parietal gliomas to characterize the impact of resection and the morbidity associated with language. ⋯ This is the largest reported experience with parietal lobe gliomas. The findings suggested that parietal language pathways are compromised at a surprisingly high rate. The proposed parietal glioma classification system is predictive of postoperative morbidity associated with language and can assist with preoperative planning. Taken together, these data emphasize the value of identifying language pathways when operating within the parietal lobe.

Randomized Controlled Trial Multicenter StudyThe effects of subthalamic and pallidal deep brain stimulation on postural responses in patients with Parkinson disease.
The effect of deep brain stimulation (DBS) for Parkinson disease (PD) on balance is unclear. The goal of this study was to investigate how automatic postural responses (APRs) were affected in patients randomized to either subthalamic nucleus (STN) or globus pallidus internus (GPi) surgery. ⋯ Turning the DBS current on improved APR stability for both STN and GPi sites. However, there was a detrimental DBS procedural effect for the STN group, and this effect was greater than the benefit of the stimulating current, making overall APR stability functionally worse after surgery for the STN group.

Randomized Controlled Trial Multicenter StudyAcute postoperative neurological deterioration associated with surgery for ruptured intracranial aneurysm: incidence, predictors, and outcomes.
Subarachnoid hemorrhage (SAH) results in significant morbidity and mortality, even among patients who reach medical attention in good neurological condition. Many patients have neurological decline in the perioperative period, which contributes to long-term outcomes. The focus of this study is to characterize the incidence of, characteristics predictive of, and outcomes associated with acute postoperative neurological deterioration in patients undergoing surgery for ruptured intracranial aneurysm. ⋯ Neurological injury incurred perioperatively or in the acute postoperative period accounts for a large percentage of poor outcomes in patients with good admission WFNS grades undergoing surgery for aneurysmal SAH. Avoiding surgical factors associated with postoperative neurological deterioration and directing investigative efforts at developing improved neuroprotection for use in aneurysm surgery may significantly improve long-term neurological outcomes in patients with SAH.

Review Case ReportsHyperacute cerebral aneurysm rerupture during CT angiography.
The object of this study was to identify the clinical features and outcomes of a subgroup of patients with aneurysmal subarachnoid hemorrhage (SAH) who had active contrast extravasation from a ruptured aneurysm during initial cerebral CT angiography (CTA). ⋯ Active aneurysmal rebleeding during CTA is an uncommon but devastating event. Though the mortality of this distinct group of patients remains high, a clinical subgroup may benefit from immediate surgery. Patients with good initial neurological status who show rapid neurological deterioration may still have a favorable outcome if they undergo timely and successful decompressive surgery and proper aneurysm obliteration. Patients who present with poor neurological status do badly, and there is no effective treatment for such patients.

Cigarette smoking: a risk factor for postoperative morbidity and 1-year mortality following craniotomy for tumor resection.
Identifying risk factors for surgical morbidity and mortality might improve the safety and efficacy of neurosurgical intervention. Cigarette smoking is a relatively common practice and is associated with several adverse health outcomes. The authors examined the relationship between smoking and intraoperative blood loss, postoperative outcomes, and survival following craniotomy for tumor resection. ⋯ Current cigarette smoking is associated with poor surgical outcome and lower 1-year survival after undergoing craniotomy for tumor resection. However, quitting smoking and implementing strict smoking cessation programs may help mitigate these risks. Future research might investigate mechanisms underlying these associations.
