How inflationary gravitons affect gravitational radiation.

We include the single graviton loop contribution to the linearized Einstein equation. Explicit results are obtained for one loop corrections to the propagation of gravitational radiation. Although suppressed by a minuscule loop-counting parameter, these corrections are enhanced by the square of the number of inflationary [Formula: see text]-foldings.

Change in the epidemiology of Reiter's syndrome (reactive arthritis) in the post-AIDS era? An analysis of cases appearing in the Greek Army.

Objective: During the last 5 years we observed a significant decrease in the incidence of newly established cases of Reiter's syndrome (reactive arthritis) in Greek Army personnel. Our study was initiated to validate this observation and to evaluate a possible change in the prevalence of Reiter's syndrome (RS) associated infections.

Methods: The case records of patients with reactive arthritis (ReA) admitted during the periods 1980-83 and 1989-92 at a large Army Hospital were studied retrospectively and the cases of RS were reviewed.
