1.  Imiquimod 3.75% Cream Applied Daily to Treat Anogenital Warts: Combined Results from Women in Two Randomized, Placebo-Controlled Studies 
Objective. To evaluate if new imiquimod formulations using a shorter treatment duration are safe and efficacious to treat anogenital warts. Methods. In two studies 534 women ≥12 years of age (mean 33.4) with 2–30 warts (mean 7.9) and total wart area ≥10 mm2 (mean 166.3) were randomized (1 : 2 : 2) to placebo (106), imiquimod 2.5% (212) or 3.75% (216) creams applied once daily until complete clearance or a maximum of 8 weeks. Results. For placebo, imiquimod 2.5% and 3.75%, respectively, complete clearance of all warts was achieved in 14.2%, 28.3%, and 36.6% of women (intent-to-treat, P = 0.008 imiquimod 2.5%, and P < 0.001 3.75% versus placebo). Mean changes in wart counts were −10.7%, −50.9%, and −63.5% (per-protocol, P < 0.001 each active versus placebo) and safety-related discontinuation rates 0.9%, 1.4%, and 2.3%. Conclusions. Imiquimod 3.75% applied daily for up to 8 weeks was well tolerated and superior to placebo in treating women with external anogenital warts.

2.  Adherence and Blocking of Candida Albicans to Cultured Vaginal Epithelial Cells: Treatments to Decrease Adherence 
Background. Pathogenesis of mucosal microorganisms depends on adherence to the tissues they colonize and infect. For Candida albicans, cell surface hydrophobicity may play a significant role in tissue binding ability. Methods. A continuous cell line of vaginal epithelial cells (VEC) was grown in keratinocyte serum-free medium (KSFM) with supplements and harvested by trypsinization. VEC were combined with yeast cells to evaluate adherence and inhibition of adherence. In this experimental setup, yeast stained with fluorescein isothiocyanate were allowed to attach to VEC and the resulting fluorescent VEC were detected by flow cytometry. Results. VEC were cultured and examined daily after plating and showed morphology similar to basal epithelial cells. Culture media supplemented with estradiol showed increased VEC proliferation initially (first 24 h) but cell morphology was not altered. Fluorescinated Candida cells bound effectively to the cultured VEC. Using fresh cells exposed to various preparations of K-Y, we showed that all formulations of the product reduced Candida binding to VEC by 25% to 50%. While VEC were generally harvested for use in experiments when they were near confluent growth, we allowed some cultures to grow beyond that point and discovered that cells allowed to become overgrown or stressed appeared to bind yeast cells more effectively. Conclusion. Flow cytometry is a useful method for evaluating binding of stained yeast cells to cultured VEC and has demonstrated that commercially available products have the ability to interfere with the process of yeast adherence to epithelial cells.

3.  Predictors of Chlamydia trachomatis Infection Among Women Attending Rural Midwest Family Planning Clinics 
Objective: To determine predictors of Chlamydia trachomatis infection among women 14–24 years of age attending family planning clinics throughout a rural Midwestern state.
Methods: The study population included 16 756 women between the ages of 14 and 24 years attending family planning clinics for annual examinations throughout the state of Iowa in 1997. All women under 25 years of age having annual exams were tested for C. trachomatis during the visit. At the time of exam, both behavioral and demographic data were collected on all women participating in the study.
Results: The majority of women in the study (96%) reported no symptoms of chlamydia. Only 2.5% of all women had a positive test result. In the multivariate model, the odds ratios were significantly increased among the youngest age (14–17 years; OR = 2.2), those with mucopurulent cervicitis (OR = 3.4), cervical friability (OR = 2.2), symptomatic for infection (OR = 1.8), risk history (OR = 1.6), and black race (OR = 1.2) and predictive of a C. trachomatis infection.
Conclusions: Risk factors predictive of C. trachomatis infection among younger aged women attending family planning clinics in a Midwest rural population are consistent with predictors of infection among women attending family planning clinics across theUnited States. The overall findings suggest the importance of developing screening guidelines as a means of lowering chlamydia rates. This may be a particularly difficult task in light of the low rate of symptoms that would lead a woman to seek medical care, even in younger age women who are at higher risk. In addition, screening guidelines would be more difficult to implement in a rural setting.

4.  Blindness in a Woman With Human Immunodeficiency Virus Infection and Syphilis 
Background: A concomitant infection with human immunodeficiency virus (HIV) may alter the natural history of other infections. Several reports indicate that syphilis may behave more aggressively when HIV infection is present.
Case: A woman presented with a rash involving her hands and feet and progressive loss of the vision in her right eye. Her serologic tests for syphilis and HIV infection were positive. A diagnosis of neurosyphilis was confirmed by an analysis of cerebrospinal fluid (CSF). She was treated with high-dose intravenous (IV) penicillin. Her skin lesions resolved, but her vision did not improve.
Conclusion: The incidence of HIV infection among women is rising. A patient with HIV and syphilis may develop neurosyphilis in a much shorter time than a patient without HIV infection.
