The Centers for Disease Control and Prevention have called for studies detailing the prevalence and burden of mild traumatic brain injury (mTBI) in the outpatient clinical setting. ⋯ More than 800 000 outpatient visits for minor head injury occur each year. The diagnostics and management associated with these visits differ from those seen in the ED setting.

Classification of middle cerebral artery (MCA) aneurysms is sometimes difficult because the identification of the main MCA bifurcation, the key for accurate classification of MCA aneurysms, is inconsistent and somewhat subjective. ⋯ Studying MCA angioarchitecture and applying the 4-group classification of MCA aneurysms is practical and facilitates the accurate classification of MCA aneurysms, helping to improve surgical outcome.

Globus Pallidus Interna (GPi) deep brain stimulation (DBS) is an effective treatment for DYT1-associated dystonia, but long-term results are lacking. ⋯ GPi DBS is an effective therapy for DYT1-associated torsion dystonia. Statistically significant efficacy is maintained for up to 7 years. Neurologic complications are rare, but long-term hardware-related complications can be significant.

The Pipeline Embolization Device (PED) has emerged as a promising treatment for intracranial aneurysms. ⋯ PED therapy may have an acceptable safety-efficacy profile. The risk of complications appears to decrease dramatically with physician experience, supporting the existence of a learning curve. Patients with previously treated aneurysms have higher complication rates, whereas fusiform aneurysms achieve lower obliteration rates.
