Restoration of normal central pain processing following manual therapy in nonspecific chronic neck pain.

Objective: To determine if a 4-week manual therapy treatment restores normal functioning of central pain processing mechanisms in non-specific chronic neck pain (NSCNP), as well as the existence of a possible relationship between changes in pain processing mechanisms and clinical outcome.

Design: Cohort study.

Methods: Sixty-three patients with NSCNP, comprising 79% female, with a mean age of 45.

Formulation with an optical brightener does not increase probability of developing resistance to Spodoptera frugiperda nucleopolyhedrovirus in the laboratory.

Stilbene-derived optical brighteners can markedly enhance the insecticidal activity of certain baculoviruses. We evaluated the influence of an optical brightener on the rate at which Spodoptera frugiperda (J.E.

Severe interaction between ritonavir and acenocoumarol.

Objective: To report a clinically severe interaction between ritonavir (RTV) and acenocoumarol resulting in a decrease in the anticoagulant effect severe enough to eventually preclude RTV administration.

Case Summary: An asymptomatic, HIV-infected, 46-year-old man with mitraortic prosthetic valves receiving acenocoumarol therapy started stavudine, lamivudine, and RTV 600 mg twice daily. His international normalized ratio (INR) decreased dramatically (the opposite of what should be expected).
