The Relationship between Intelligence and Anxiety: An Association with Subcortical White Matter Metabolism.

We have demonstrated in a previous study that a high degree of worry in patients with generalized anxiety disorder (GAD) correlates positively with intelligence and that a low degree of worry in healthy subjects correlates positively with intelligence. We have also shown that both worry and intelligence exhibit an inverse correlation with certain metabolites in the subcortical white matter. Here we re-examine the relationships among generalized anxiety, worry, intelligence, and subcortical white matter metabolism in an extended sample.

Efalizumab: a biological agent for the treatment of psoriasis.

Efalizumab is a humanized, monoclonal IgG1 antibody that binds to the alpha-subunit of lymphocyte function associated antigen (LFA)-1, blocking the interaction between LFA-1 and intercellular adhesion molecule-1. The result is a reduction in T cell activation, an inhibition of the trafficking and recruitment of T cells to the dermis and epidermis, and a decrease in the reactivation of T cells at several steps in the psoriasis pathogenesis. The clinical responses seen in efalizumab trials have demonstrated that this medication is efficacious, especially in long-term treatment.

Combination therapy with acitretin for psoriasis.

Numerous therapies exist for the treatment of psoriasis. A complete understanding of the benefits and potential risks of all therapeutic options is requisite in selecting an appropriate regimen for each patient. This paper examines the effectiveness of combination therapy with acitretin in treating difficult cases of psoriasis, which may require systemic medication or phototherapy.
