Comparative Study Observational Study
Comparison of Low-Profiled Visualized Intraluminal Support Stent-Assisted Coiling and Coiling Only for Acutely Ruptured Intracranial Aneurysms: Safety and Efficacy Based on a Propensity Score-Matched Cohort Study.
Low-profiled visualized intraluminal support (LVIS) is suggested as a promising stent for complex intracranial aneurysms. However, the safety and efficacy of LVIS-assisted coiling of acutely ruptured wide-necked intracranial aneurysms have not been well reported. ⋯ The LVIS stent is a safe and effective device for stent-assisted coiling of acutely ruptured wide-necked intracranial aneurysms, with comparable procedure-related complication rates, higher complete occlusion rates, and lower recurrence rates at follow-up compared with coiling only.

Multicenter Study
Early Multicenter Experience With the Neuroform Atlas Stent: Feasibility, Safety, and Efficacy.
The Neuroform Atlas stent™ (by Stryker, Fremont, California) represents the most recent widely available upgrade to intracranial stenting, providing a laser cut open cell stent with a diameter of 3.0 to 4.5 mm that is delivered through an 0.017-inch microcatheter. ⋯ Our series demonstrates the safety, feasibility, and efficacy of the Atlas stent. The low complication rate and the high obliteration rate managing complex aneurysms, even in an acute ruptured setting, are notable.

Optimal postoperative pain control is critical after spinal fusion surgery. There remains significant variability in the use of postoperative intravenous opioid patient-controlled analgesia (PCA) and few data evaluating its utility compared with nurse-controlled analgesia (NCA) among patients with lumbar fusion. ⋯ Postoperative PCA is associated with significantly more opioid consumption in the first 72 h after surgery and equal or worse postoperative pain scores compared with NCA after lumbar spinal fusion surgery.

Over 90 000 people are expected to be diagnosed with melanoma in the United States this year. The development of brain metastases is particularly difficult to manage. Over the past few years, melanoma patients with multiple unresectable brain metastases for which stereotactic surgery might also not be a viable option have fortunately experienced a dramatic expansion in available management options given improvements made to targeted agents, immunotherapy, and radiotherapy. ⋯ In this review, we summarize retrospective and prospective studies on individual advances in targeted agents, immunotherapy, and WBRT, highlighting important variables such as overall survival, intracranial progression-free survival, control and response rates, and toxicities. We also discuss the recent integration of these therapies into a multimodality approach, which has shown promise in the clinical setting although toxicities have not been insignificant. Finally, we describe ongoing prospective trials relevant to melanoma with brain metastases, and we conclude with our own thoughts on the optimal approach for these patients.

Stereotactic radiosurgery (SRS) is a safe and effective treatment for acromegaly. ⋯ IGF-1i is a reliable predictor of biochemical remission after SRS. BED appears to predict biochemical outcome more reliably than radiation dose, but confirmatory study is needed.
