Risk of Allergic Reactions to Recurrent Intravenous Penicillin Administration in Penicillin Skin Test Negative Patients.

Background: Patients with a history of penicillin allergy who are found to be skin test negative to penicillin are able to tolerate repeated oral doses of penicillin with low rates of resensitization. However, the resensitization rate after repeated doses of intravenous penicillin is less clear.

Objective: We sought to evaluate the risk of allergic reactions to repeated doses of intravenous penicillin in patients who previously reported penicillin allergy and were found to be penicillin skin test and oral challenge negative.

Constrictive pericarditis presenting as a calcified anterior cardiac mass.

A primer on quality indicators of distance education.

In the past decade, there has been an enormous growth of distance education courses and programs in higher education. The growth of distance education is particularly evident in the field of health education. However, the enormous potential of distance education is tempered by one overriding question: How does one ensure that distance education coursework and degrees are of high quality? To this end, the purpose of this study is twofold: to identify quality indicators of distance education and to provide implications of the identified quality indicators for health education researchers and practitioners.
