Multiple sclerosis (MS) is a complex, heterogeneous disease. Standard treatment of relapsing MS includes interferon beta (IFNbeta) and glatiramer acetate. These agents reduce relapse rates, and IFNbeta-1a is associated with a slowing of disease progression. Despite treatment, many patients experience disease progression, prompting neurologists to use combination therapies to delay this progression. Agents that may be considered for combination therapy are those with unique mechanisms of action that exert additive or synergistic efficacy. This article reviews combination treatment with immunosuppressive therapies and new agents for the management of MS. ⋯ Combination of standard therapies with immunosuppressive agents or with new therapies may provide synergistic effects that will likely benefit patients with MS. Larger, well-controlled trials need to be conducted.

One strategy of reducing the burden of stroke is the prevention of recurrent stroke, following an initial ischaemic stroke or transient ischaemic attack (TIA) of arterial origin, by means of antiplatelet therapy. ⋯ Whilst awaiting the results of the PRoFESS trial, the combination of dipyridamole plus aspirin is the preferred antiplatelet regimen to reduce the risk of recurrent vascular events among patients with TIA and ischaemic stroke of arterial origin.

To evaluate the effect of triamcinolone acetonide (ITA) on intraocular pressure (IOP) following intravitreal injection, and, in those patients who experience post-injection elevation of IOP, to determine the time course, effect of multiple injections, and risk factors for the pressure rise. ⋯ ITA is frequently associated with a significant elevation in IOP, typically within the first 2-months after injection. Most patients who do not have an elevated IOP after an initial injection will not experience a pressure rise after an additional one. About one-third will require topical glaucoma therapy for IOP control. Patients with OAG may be more difficult to control and require a longer duration of therapy. The inconsistent post-injection follow-up visit intervals among patients in this retrospective review may have affected our results, as some patients with maximum IOP changes may have been missed between office visits. In addition, practice patterns among treating physicians typically differ as to thresholds for the treatment of elevated IOP. A randomized, prospective, controlled trial could better address these issues.

Duloxetine is a serotonergic noradrenergic reuptake inhibitor with demonstrated efficacy in each of three independent studies for treatment of adults with generalized anxiety disorder (GAD). A pooled dataset from all completed trials is provided here to show the most likely clinical outcomes associated with duloxetine treatment for GAD. ⋯ In this sample of more than 1100 patients, duloxetine was efficacious for reducing anxiety severity and for increasing patients' overall role functioning in GAD.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized, controlled trial comparing darbepoetin alfa correction/maintenance dosing with weekly dosing for treating chemotherapy-induced anemia.
To evaluate if a darbepoetin alfa correction/maintenance dosing regimen is non-inferior to a weekly regimen with respect to red blood cell transfusion requirements in patients with chemotherapy-induced anemia (CIA). ⋯ A correction/maintenance schedule with its initial two-fold higher weekly dosing and subsequent Q3W dosing yielded outcomes similar to those observed with a weekly schedule. Although correction/maintenance dosing provided no incremental clinical benefit, Q3W dosing could provide benefits of convenience and facilitate patient compliance.
