Improving patient safety in the intra-operative MRI suite using an on-duty safety nurse, safety manual and checklist.
This paper describes the use of an on-duty safety nurse, a surgical safety manual and a checklist as an essential precursor to evaluating how these approaches affect surgical quality, communication in surgery crews and contribute to the safety of surgical care in the intra-operative magnetic resonance imaging (MRI) suite.

Studying discovertebral complex anatomy is extremely important for the understanding of the pathophysiology of disc degeneration which leads to vertebral endplates signal changes, also known as Modic changes. The sequelae of disc degeneration are among the leading causes of functional incapacity in both sexes and are one of the most common sources of chronic disability in the working years. Even if the presence of degenerative changes in MRI of the spine is by no means an indicator of symptoms, we are concordant in a positive association between Modic changes and low back pain, above all as a relatively specific but insensitive sign of discogenic low back pain.

Evidenced Based Guidelines for the Management of Good Grade Subarachnoid Haemorrhage Patients in Leeds, UK.
Aneurysmal Subarachnoid Haemorrhage (SAH) is a common neurosurgical condition with high morbidity and mortality, with our trust treating over 120 patients annually. Although there are recommendations for the management of some aspects of subarachnoid haemorrhage, a comprehensive guideline document has not been produced. Our guidelines seek to address all aspects of acute patient care in our neurosurgical unit, using evidence based medicine with a multi-disciplinary team to produce care pathways establishing a standard of care for our patients.

Randomized Controlled Trial Multicenter StudyClazosentan: prevention of cerebral vasospasm and the potential to overcome infarction.
Cerebral vasospasm is a common complication occurring after aneurysmal subarachnoid hemorrhage (SAH). It is recognized as a leading preventable cause of morbidity and mortality in this patient group, but its management is challenging, and new treatments are needed. Clazosentan is an endothelin receptor antagonist designed to prevent endothelin-mediated cerebral vasospasm. ⋯ Clazosentan reduced angiographic vasospasm dose-dependently relative to placebo with a maximum risk reduction of 65% with the highest dose. Despite this, there was no benefit of clazosentan on the secondary protocol-defined morbidity/mortality endpoint; however, additional post-hoc and modified endpoint analyses provided some evidence for a potential clinical benefit. Two additional large-scale studies (CONSCIOUS-2 and CONSCIOUS-3) are now underway to further investigate the potential of clazosentan to improve long-term clinical outcome.

ReviewPeriduroscopy: general review of clinical features and development of operative models.
Myeloscopy is a useful approach for both diagnosis and treatment of back pain. However clinicians have underestimated its potential. From the nineties myeloscopy has been used only as a diagnostic tool, without any improvement of the technique. Racz's method is nowadays still used for the lysis of adherence by applying medical solutions without a direct vision inside the spinal channel. In 1998 we showed the limitations of Racz's approach, and in 1999 we developed a new technique, introducing a Fogarty balloon to remove the occlusions of the spinal canal and the resaflex for the lysis of adherence at low temperature (Raffaeli-Righetti technique). In this paper we report a general review of our experience with periduroscopy for the treatment of failed back surgery syndrome (FBSS) and spinal stenosis. ⋯ myeloscopy technique enlightens pain-triggering mechanisms otherwise unrevealed; it has specific therapeutic value, whereas on the diagnostic side it has not revealed relevant pathologies. Its effectiveness in FBSS patients is high, with the advantage of its relatively easy implementation, limited invasiveness and repeatability.
