The fact that Schaaf et al1 did not include testing for gonorrhea and chlamydial infection in their evaluation of patients who presented with vaginal symptoms significantly limits the usefulness of their findings. Women with symptoms of possible acute pelvic inflammatory disease were appropriately excluded from the study, but this does not eliminate the need to test for gonorrhea and chlamydial infection. Many women (often the majority) with these two infections have mild symptoms or no symptoms2; therefore, limiting investigation of vaginal/urethral symptoms to only Candida, Trichomonas, and bacterial vaginosis is an important oversight.

Schachter noted that 70% of these infections
