Complex regional pain syndrome (CRPS) is a multifaceted disorder resulting in an abnormal pain response to tissue injury. Among key CRPS features are neurogenic inflammation, maladaptive plasticity, and vasomotor dysfunction, which can result in severe pain and disability. Spinal cord stimulation (SCS) is an efficacious treatment for several chronic pain conditions and may improve pain and life quality in CRPS patients with CRPS. However, little information exists regarding perioperative outcomes of patients with CRPS undergoing surgical implantation of an SCS device. ⋯ Our data suggest that CRPS may pose several unique risks in the perioperative period after inpatient SCS implantation. These findings support the need for future prospective investigations examining risks and outcomes for SCS procedures in this population.

Review Case Reports
Cutaneous Metastasis from Cervical Spinal Chordoma: Case Report and Literature Review.
Chordomas are rare primary tumors of the bone that arise from embryonic notochord. They are locally aggressive tumors with a high tendency for postsurgical recurrence. On the other hand, distant metastases are rare. When they occur, they involve lungs, liver, lymph nodes, and bones. Skin and subcutaneous tissue involvement is even rarer and usually occurs by direct extension of the primary tumor or by local recurrence. Distant cutaneous metastasis from chordoma is an exceptional finding, with fewer than 20 cases reported in the literature. All the cutaneous metastases described derive from sacral chordomas, except for 2 cases in which the source of metastasis is skull-base chordomas. ⋯ Metastasis has to be taken into account in the differential diagnosis when a new skin lesion appears in a patient with a past medical history of chordoma. To the best of our knowledge, this is the first case of cutaneous metastasis from spinal cervical chordoma. A systematic literature review was performed.

Review Meta Analysis Comparative Study
Microsurgical clipping compared to new and most advanced endovascular techniques in the treatment of unruptured middle cerebral artery aneurysms: a meta-analysis in the modern era.
Analyzing occlusion, complications rate, and clinical results in unruptured saccular middle cerebral artery aneurysms (MCAAs) comparing clipping with the most advance and newer endovascular techniques. ⋯ Treatment-related complication and mortality are comparable among these techniques and the risk of aneurysm rupture seems very low for both strategies. The endovascular approach seems to increase the probability of good functional outcome after treatment, compared with surgery.

Cerebral venous thrombosis (CVT) is a rare type of stroke whose pathophysiology differs from arterial stroke. CVT is treated with systemic anticoagulant therapy even in the setting of intracerebral hemorrhage. Patients who do not respond adequately may require decompressive surgery. The study objective was to examine the timing of anticoagulation in patients with CVT who require decompressive surgery through systematic literature review and consecutive case series. ⋯ Despite the lack of high-quality studies, this systematic review of patients with CVT requiring decompressive surgery indicates that anticoagulation can be safely initiated or resumed around 24-48 hours postoperatively; our series supports the existing literature.

Normal pressure hydrocephalus (NPH) is a syndrome that was characterized several decades ago; however, its optimal diagnosis and management remain unclear. Our objective was to evaluate citation and bibliometric characteristics of the 100 most cited articles about NPH to better understand the state of research efforts in the field and where improvements may arise. ⋯ In the 100 most cited articles about NPH, there has been a distinct shift toward a more globalized effort in recent decades. The lack of more impactful articles in recent decades highlights that particular classic studies still penetrate practice and the possible need to reconsider our contemporary views on NPH to further advance the field.
