Interferon beta (IFNbeta) is the first-line treatment for patients diagnosed with multiple sclerosis (MS). In patients with MS who experience breakthrough disease while receiving treatment with IFNbeta, it is common clinical practice to administer additional therapeutic agents. ⋯ Agents used concomitantly have the potential to exert synergistic effects and slow the progression of disease in patients who experience breakthrough disease. Concomitant therapies that have been reported in patients with MS are reviewed here.

To investigate cerebral activity associated with allodynia in patients with neuropathic pain. ⋯ On a background of deafferentation in the hemisphere contralateral to stimuli, enhanced or additional responses to innocuous stimuli in the ipsilateral hemisphere may contribute to the shift of perception from innocuous toward painful and ill-defined sensations.

Randomized Controlled Trial Multicenter Study Clinical Trial
Repeated dosing of botulinum toxin type A for upper limb spasticity following stroke.
The authors evaluated the long-term efficacy and safety of botulinum toxin type A (BTX-A) in poststroke spasticity patients who completed a 12-week placebo-controlled study and received multiple open-label treatments with 200 to 240 U BTX-A for 42 weeks. Significant and sustained improvements were observed for Disability Assessment and Ashworth scores. Adverse events were generally mild. This extension of a double-blind study demonstrates that repeated treatments of BTX-A significantly improve function and tone in spasticity.

Although cardiac arrest (CA) is commonly cited as a cause of amnesia, patients referred to the authors' center with a diagnosis of "amnesia" after CA rarely have isolated memory deficits. ⋯ Diffuse, sudden ischemic-hypoxic injury caused by cardiac arrest (CA) does not preferentially damage memory systems. Subacute or stepwise hypoxic or excitotoxic injury may cause isolated hippocampal injury and amnesia. The common pattern of impairment in the postacute phase after CA is a combination of memory, subtle motor, and variable executive deficits.
