`
`Results: CDMS and TCCS—ECD venous outflow anomalies
`
`were dramatically associated (OR 43, 95% Cl 29 to 65.
`p<0.0001). Subsequently, venography demonstrated in
`CDMS, and not in controls, the presence of multiple
`severe extracranial stenosis, affecting the principal
`cerebrospinal venous segments; this provides a picture of
`chronic cerebrospinal venous insufficiency (CCSVI) with
`four different patterns of distribution of stenosis and
`substitute circle. Moreover, relapsing-remitting and
`secondary progressive courses were associated with
`CCSVI patterns significantly different from those of
`primary progressive (p<0.0001). Finally, the pressure
`gradient measured across the venous stenosies was

`Conclusion: CDMS is strongly associated with CCSVI, a
`scenanothathas notpueWOUSW been descnbed,
`characteNSed by abnonnalvenous haernodynanflcs
`determined by extracranial multiple venous strictures of
`unknown origin. The location of venous obstructions plays

`
`Sativex® oromucosal spray for spasticity due to
`multiple sclerosis
`The North East Treatment Advisory Group
`considered the use of Sativex®, a cannabinoid
`oromucosal spray, for use within its licensed
`indication for the treatment of moderate to severe
`spasticity due to multiple sclerosis
`Sativex® is not recommended for use within
`NHS North East for the treatment of spasticity
`due to multiple sclerosis.
`Clinical evidence for the efficacy of Sativex® was
`considered to be of low quality and demonstrated
`a modest but clinically unclear benefit. Combined
`with a high acquisition cost, Sativex® was
`considered unlikely to meet conventional cost-
`effectiveness criteria.
`Individual patients in exceptional circumstances
`may be suitable for treatment. Such cases must
`be referred via local individual funding request
`mechanisms.

`
`Sustained-release oral fampridine in multiple sclerosis: a randomised,
`double-blind, controlled trial
`
`Summary
`
`The proportion of timed walk responders was higher in the fampridine group (78/224 or
`35%) than in the placebo group (6/72 or 8%; p<0·0001). Improvement in walking speed in
`fampridine-treated timed walk responders, which was maintained throughout the treatment
`period, was 25·2% (95% CI 21·5% to 28·8%) and 4·7% (1·0% to 8·4%) in the placebo
`group. Timed walk responders showed greater improvement in 12-item multiple sclerosis
`walking scale scores (−6·84, 95% CI −9·65 to −4·02) than timed walk non-responders (0·05,
`−1·48 to 1·57; p=0·0002). Safety data were consistent with previous studies.
`Fampridine improved walking ability in some people with multiple sclerosis. This
`improvement was associated with a reduction of patients' reported ambulatory disability,
`and is a clinically meaningful therapeutic benefit
