Observational Study
The Effects of Red Blood Cell Transfusion on Functional Outcome after Aneurysmal Subarachnoid Hemorrhage.
The optimal red blood cell transfusion (RBCT) trigger for patients with aneurysmal subarachnoid hemorrhage (SAH) is unknown. In patients with cerebral vasospasm, anemia may increase susceptibility to ischemic injury; conversely, RBCT may worsen outcome given known deleterious effects. ⋯ Blood transfusions are associated with unfavorable outcome after SAH particularly when DCI is absent. Propensity analysis suggests that RBCT may be associated with poor outcome rather than being a marker of disease severity. However, when DCI is present, RBCT may help improve outcome.

Minimally Invasive treatment for a Sacral Tarlov Cyst through tubular retractors: Case report.
Tarlov cysts (TC) are focal dilations of arachnoid and dura mater of the spinal posterior nerve root sheath that appear as cystic lesions of the nerve roots typically in the lower spine, especially in the sacrum, which can cause radicular symptoms when they increase in size and compress the nerve roots. Different open procedures have been described to treat TCs, but no minimally invasive procedures have been described to effectively address this pathology. ⋯ Minimally invasive spine surgery through tubular retractors can be safely performed for successful excision and ligation of TC using a Scanlan modified technique.

We tested the prognostic value of cumulative intracranial tumor volume (CITV) in the context of a disease-specific Graded Prognostic Assessment (ds-GPA) model for renal cell carcinoma (RCC) patients with brain metastasis (BM) treated with stereotactic radiosurgery (SRS). ⋯ CITV is an important prognostic variable in SRS-treated RCC patients with BM. The prognostic value of the ds-GPA scale for RCC brain metastasis was enhanced by the incorporation of CITV.

To compare 2 craniotomy approaches (unilateral and bilateral) in terms of anatomic and clinical parameters and surgical outcomes. ⋯ Bilateral mini-craniotomy for the treatment of bilateral MCA aneurysms was associated with better surgical outcomes and fewer complications. Bilateral mini-craniotomy does not require as much retraction of the frontal lobe to apply a clip completely at the contralateral aneurysm. Therefore, it represents a safe and effective therapeutic option for unruptured bilateral MCA aneurysms.

Case Reports
Metastatic Basal Cell Adenocarcinoma of Submandibular Gland to the Spine: An Extremely Rare Condition. A Case Report.
Basal cell adenocarcinomas are rare malignant neoplasms of salivary glands, accounting for <1% of salivary gland tumors. Few cases of distant metastases have been reported. ⋯ This case highlighted an extremely rare condition of metastatic basal cell adenocarcinoma of the submandibular gland to the lung and spine, which, to our knowledge, has not been previously reported in the literature.
