    Title Are Corticosteroids Efficacious for Preventing or Treating Neutralizing Antibodies in Multiple Sclerosis Patients Treated with Beta-interferons? A Critically Appraised Topic.
    Date August 2010
    Journal The Neurologist

    Persistent, high-titer neutralizing antibodies (NAbs) reduce or eliminate the biologic activity of interferon-beta (IFNB) therapies for multiple sclerosis (MS) and are associated with reduction in efficacy. Most patients who develop NAbs have preceding detectable binding antibodies. There is no consensus on prevention or management of NAb-positive patients but switching to noninterferon therapy and use of immunosuppressive strategies, especially corticosteroids, has been proposed.

    Title The Role of Corticosteroids in the Management of Chronic Subdural Hematomas: a Critically Appraised Topic.
    Date December 2009
    Journal The Neurologist

    Chronic subdural hematomas (CSDH) occur most commonly in the elderly population. When CSDH patients present with a moderate or severe neurologic deficit and are good surgical candidates, surgery is regarded as the ideal option. However, CSDH patients often have only mild neurologic deficits or are not optimal candidates for surgery. Corticosteroids are often used on these subgroups, but the benefit of this intervention is unknown. Optimal treatment for these patients is not well established.
