Radiosurgery for Treatment of Renal Cell Metastases to Spine: A Systematic Review of the Literature.
The incidence of renal cell carcinoma (RCC) continues to increase, and the spine is the most common site for bony metastasis. Radiation therapy is one treatment for spinal RCC metastasis. Stereotactic body radiotherapy (SBRT) is a newer treatment that reportedly has benefits over conventional external beam radiotherapy. This study systematically reviewed the current literature on SBRT for metastatic RCC to spine. ⋯ Use of SBRT for spinal metastasis from RCC resulted in significant local control and pain outcomes. There is a risk of VCF with SBRT; however, treatment seems to be well tolerated with few serious side effects. There is continued need for long-term prospective studies investigating the optimal role of SBRT in the treatment algorithm of RCC spinal metastases.

Review Case Reports
Arachnoid cyst associated chronic subdural hematoma: report of 14 cases and a systematic literature review.
Arachnoid cyst (AC)-associated chronic subdural hematoma (CSDH) differs significantly from its counterparts without AC in epidemiologic, demographic, and clinical characteristics, as well as in management and prognosis. This study was conducted to further examine the epidemiologic, demographic, and clinical characteristics; diagnosis; treatment; and prognosis of AC-associated CSDH. ⋯ CSDH is a rare complication in patients with intracranial AC. Male children, juveniles, and young adults with recent head trauma or sport-related injury are most commonly inflicted. Burr hole drainage is the first-choice surgical procedure in symptomatic patients and is still effective in some recurrent cases. Fenestration or resection of the AC membrane is not a requisite in patients with previous asymptomatic AC.

Randomized Controlled Trial Comparative Study
Comparative Study of Cortical Bone Trajectory-Pedicle Screw (Cortical Screw) versus Conventional Pedicle Screw in Single-Level Posterior Lumbar Interbody Fusion: A 2-Year Post Hoc Analysis from Prospectively Randomized Data.
The aim of this study was to report 2-year follow-up outcomes of posterior lumbar interbody fusion (PLIF) with cortical bone trajectory-pedicle screw (CS), in terms of fusion rates, clinical outcomes, surgical outcomes, and complications, and to compare these outcomes with outcomes for PLIF with conventional pedicle screw (PS). ⋯ We suggest that CS in single-level PLIF may be an alternative to PS.

Collateral artery aneurysms are a source of intracranial hemorrhage in moyamoya disease. Several reports have shown that surgical revascularization leads to the obliteration of collateral artery aneurysms. However, its effect on the prevention of rebleeding has not been established, and the optimal timing of the operation remains unclear. The purpose of the present study is to evaluate the effects of surgical revascularization and to investigate the optimal operation timing in patients with moyamoya disease who have ruptured collateral artery aneurysms on the ventricular wall. ⋯ Because ruptured collateral artery aneurysms on the wall of the lateral ventricle in moyamoya disease are prone to rerupture within 1 month, surgical revascularization may be recommended as soon as the patients are stable and able to withstand the operation.

Randomized Controlled Trial
Postoperative Intravenous Acetaminophen for Craniotomy Patients: A Randomized Controlled Trial.
To determine whether opioids during the first 24 postoperative hours were significantly altered when receiving intravenous (IV) acetaminophen during that time compared with those receiving placebo (normal saline). ⋯ The opioid requirements within the first 24 postoperative hours were similar in the placebo and acetaminophen groups. This study is informative for the design and planning of future studies investigating the management of postoperative pain in patients undergoing craniotomies.
