Based on class-I studies, sodium oxybate is regarded as a first-line treatment for both EDS and cataplexy. The cost-effectiveness of sodium oxybate is largely unknown, though. In this study, we estimate the cost-effectiveness of sodium oxybate as treatment for patients with narcolepsy as compared to standard treatment, by calculating incremental cost-effectiveness ratios (cost per quality-adjusted life year, QALY) for patients in a Swedish setting. ⋯ The estimated cost per additional QALY for the sodium oxybate treatment alternative compared with standard treatment was estimated above the informal Swedish willingness-to-pay threshold (SEK 500,000). The estimated cost per additional QALY obtained here is likely to overestimate the true cost-effectiveness ratio as potentially beneficial effects on productivity of treatment with sodium oxybate were not included (due to lack of data).

ReviewThe clinical utility of JC virus antibody index measurements in the context of progressive multifocal leukoencephalopathy.
In natalizumab-treated patients without previous immunosuppressive treatment, the JCV antibody index is used to stratify PML risk. A high index value indicates that the risk to develop PML is significantly elevated, although probably about 99% of patients with this index value will not develop PML. This minireview aimed to provide an overview of the basic virology and immunology relevant to understanding JCV infections in MS patients, with a focus on what is presently known about antibodies to JCV and how they could be of use to predict and diagnose PML.

Randomized Controlled TrialRandomized controlled trial of local progesterone vs corticosteroid injection for carpal tunnel syndrome.
A number of studies have demonstrated the neuroprotective effects of progesterone and its influence on the recovery after neural injury. Few studies investigated the efficacy of local progesterone in carpal tunnel syndrome. The objective of this study was to compare the long-term effects of progesterone vs corticosteroid local injections in patients with mild and moderate carpal tunnel syndrome. ⋯ The efficacy of progesterone local injection in mild and moderate CTS is equal and somehow superior to corticosteroid injection for relieving symptoms and improving functional and electrophysiologic findings at long-term follow-up.

Identifying patients at risk of acute symptomatic seizure after ischemic stroke.
Contributors to post-stroke seizure research have advocated the need for prospective studies of acute symptomatic seizures after stroke. Identification of the patient at risk of seizure and the impact of the event on outcome is a prerequisite for this kind of research. The aim of this study was to identify risk factors, make an outline for a risk score, and look at consequences of seizure on short-time clinical outcomes. ⋯ Because of low incidence and the lack of specific risk factors, acute symptomatic seizure after ischemic stroke is hard to predict. The negative effect of seizure on stroke outcome is uncertain, and more thorough studies are needed because of possible subtle or non-overt seizures.

Randomized Controlled TrialThe efficacy of greater occipital nerve blockade in chronic migraine: A placebo-controlled study.
GON blockade with local anesthetics is an effective treatment for a group of headaches, such as cervicogenic headache, cluster headache, occipital neuralgia, migraine. Our aim was to evaluate the efficacy of greater occipital nerve (GON) blockade in patients with chronic migraine (CM) by using a control group. ⋯ Our results suggest that GON blockade with bupivacaine was superior to placebo, has long-lasting effect than placebo, and was found to be effective for the treatment of CM. More studies are needed to better define the safety and cost-effectiveness of GON blockade in CM.
