Review Comparative StudyCoronary artery thrombolysis: comparison of approved agents.
Three agents approved for the lysis of thrombi in coronary arteries--alteplase, anistreplase and streptokinase--have undergone critical clinical experimental trials in Europe and the United States. Global comparison of their efficacy shows that alteplase is slightly more effective (71 percent) in restoring patency than anistreplase (60 percent) and streptokinase (58 percent). ⋯ A recanalization rate of 90 percent or more could be achieved if the thrombolytic agent is administered within the first hour after thrombosis. Administration this soon after the development of thrombosis may be possible if the agent is given outside the hospital by practicing physicians or, perhaps, paramedics.

Herpes zoster results from reactivation of latent varicella-zoster virus. It is most common in elderly patients and immunosuppressed patients, especially those with human immunodeficiency virus (HIV) infection. Zoster is often the earliest indicator of HIV infection. ⋯ High-dose acyclovir (800 mg orally five times daily) has recently been approved for treatment of herpes zoster and, if started early, decreases the duration and severity of symptoms. In the prevention of postherpetic neuralgia, acyclovir does not appear to be effective, and the efficacy of steroids is questionable. The best therapy currently available for postherpetic neuralgia is amitriptyline, topical capsaicin and transcutaneous electrical stimulation.

Family physicians can manage most finger injuries, including uncomplicated fractures, proximal interphalangeal joint dislocations, closed tendon injuries and ligament sprains. Finger injuries that can cause long-term morbidity may present as minor sprains. Diagnosis requires a thorough history, systematic examination and radiographic evaluation.
