Randomized Controlled Trial
Clazosentan, an endothelin receptor antagonist, in patients with aneurysmal subarachnoid haemorrhage undergoing surgical clipping: a randomised, double-blind, placebo-controlled phase 3 trial (CONSCIOUS-2).
Clazosentan, an endothelin receptor antagonist, significantly and dose-dependently reduced angiographic vasospasm after aneurysmal subarachnoid haemorrhage (aSAH). We investigated whether clazosentan reduced vasospasm-related morbidity and all-cause mortality. ⋯ Actelion Pharmaceuticals.

A complex regional pain syndrome (CRPS)--multiple system dysfunction, severe and often chronic pain, and disability--can be triggered by a minor injury, a fact that has fascinated scientists and perplexed clinicians for decades. However, substantial advances across several medical disciplines have recently improved our understanding of CRPS. ⋯ Collectively, the evidence points to CRPS being a multifactorial disorder that is associated with an aberrant host response to tissue injury. Variation in susceptibility to perturbed regulation of any of the underlying biological pathways probably accounts for the clinical heterogeneity of CRPS.

Review
Mesenchymal stem cells for the treatment of multiple sclerosis and other neurological diseases.
The rationale for use of adult stem cells as a treatment for neurological diseases such as multiple sclerosis arose from the hope that they had the capacity to foster repair of the CNS through tissue integration and differentiation into neural cells. Evidence from preclinical studies suggested that mesenchymal stem cells (MSCs), a subset of adult progenitor cells, are an effective therapy in preclinical animal models of neurological diseases such as experimental autoimmune encephalomyelitis, a model for multiple sclerosis, and stroke. ⋯ These results led to the conclusion that therapeutic use of MSCs should initially focus on individuals with multiple sclerosis and persistent inflammation. Small clinical studies in different neurological diseases have suggested that MSCs are safe, paving the road for larger phase 2 studies addressing the effect of MSCs on clinical outcomes and markers of disease activity.
