Human Papillomavirus Vaccine: For Boys, Too?

The new quadrivalent Human Papillomavirus (HPV) L1 virus-like particle vaccine (types 6, 11, 16, 18) was studied for immunogenicity and reactogenicity in 506 girls and 510 boys (10-15 years of age) and 513 young women (16-23 years of age). Vaccine was administered in the standard schedule of 0, 2, and 6 months. Type-specific serologies were performed in a blinded fashion using a competitive Luminex xMAP-based immunoassay (cLIA) on serum samples obtained at 0, 3, and 7 months.

Panton-Valentine Leukocidin

Community-Associated MRSA (CA-MRSA) has emerged as an important cause of skin and soft-tissue infection. Most isolates of CA-MRSA are positive for the Panton-Valentine leukocidin (PVL), an exotoxin that is generally absent from "classic" hospital-associated MRSA strains. This suggests that PVL may be an important virulence determinant in CA-MRSA.

TMC125 (Etravirine), a Second Generation Non-Nucleoside Reverse Transcriptase Inhibitor

The Non-nucleoside Reverse Transcriptase inhibitors (nnRTI's) including both efavirenz and nevirapine have intrinsic in vitro activity superior to all the other classes of antiretroviral agents. Clinical trials including patients who have been followed now for many years on efavirenz have demonstrated the durability, as well as potency, of these agents.
