“…Using a positive PCR test on endocervical swab specimens exclusively or in combination with positive results from at least two specimens to identify infected patients, or using the latent class model that does not assume any gold standard (29), the relative sensitivity and specificity of PCR on sanitary napkin specimens were 92 to 100% and 98 to 99%, respectively. These values are similar to those reported with vaginal swab specimens obtained by health care providers (22,26,31,33) and are similar to or slightly higher than those reported with self-collected vaginal swab specimens (2,5,9,15,16,31) or vaginal tampon specimens (13,(23)(24)(25).…”

“…More recently, detection of chlamydial infection by these techniques has also been assessed on secretions recovered from vaginal introitus collected by clinicians or patients themselves (2,5,9,15,16,22,26,31,33) or from vaginal tampons (13,(23)(24)(25). Urine and self-collected samples represent easy and noninvasive techniques compared to the usual cervical swabbing, which necessitates vaginal speculum insertion and a gynecologic examination.…”

A modified sanitary napkin was compared with endocervical swab and urine specimens for the detection of urogenital Chlamydia trachomatis infection. Endocervical swabs and/or first-catch urine were collected from 510 women at medical or community settings in Quebec City. Participants were also asked to wear a modified sanitary napkin (Ezy-Detek) during 4 consecutive hours and to bring it back to the clinic or mail it to the laboratory. Endocervical and urine specimens were tested using the Cobas Amplicor CT/NG assay (Roche Diagnostic Systems) according to the manufacturer's instructions, as were specimens collected with the napkin after adequate preparation. If the PCR test result was positive on the endocervical sample or on any two samples, a woman was considered to be infected. PCR testing results on paired samples were identical for 493 Chlamydia trachomatis infection is the most frequently reported sexually transmitted disease in the industrialized countries. The association of this infection with transmission of human immunodeficiency virus infection, pelvic inflammatory disease, infertility, ectopic pregnancy, and chronic pelvic pain (10, 20, 30) constitutes a major public health concern. Because most infected women have no specific symptoms or are asymptomatic, screening programs represent one of the main approaches to control this infection (20,21).The current literature provides very good information on the value of gene amplification techniques, such as PCR or ligase chain reaction, for the detection of C. trachomatis in the lower genital tracts of women. Both technologies have been evaluated in depth using endocervical swab or urine samples. With a specificity higher than 98%, the sensitivity of PCR on either cervical specimens or urine samples varies from 80.0 to 100% (4,12,18,19,27,28).More recently, detection of chlamydial infection by these techniques has also been assessed on secretions recovered from vaginal introitus collected by clinicians or patients themselves (2,5,9,15,16,22,26,31,33) or from vaginal tampons (13,(23)(24)(25). Urine and self-collected samples represent easy and noninvasive techniques compared to the usual cervical swabbing, which necessitates vaginal speculum insertion and a gynecologic examination. In a study, as many as 60% of chlamydia-infected adolescents would have been missed if the urine screening program had not been in place, because they refused the gynecologic examination (14). In addition, specimens may be collected in nontraditional medical settings, such as community centers and schools, and eventually at home (6,11,15,17). Although these methods have been shown to be relatively easy to use and sensitive for the detection of C. trachomatis, some women failed to collect adequate specimens or did not feel at ease with the technique (2,16,31). The objective of the present study was to evaluate a modified sanitary napkin (Ezy-Detek [EDI] Inc., Sillery, Canada) as a specimen self-collection device for detection of chlamydial infection in women.

“…Probably several times as many work in this very transient sector of the sex industry during any one year. Notably a comparable number of sex workers solicit on the streets of Melbourne (Morton 1999) where street sex work is illegal and the potential client base is smaller. This suggests that the law has little effect on the presence of street prostitution.…”

“…In the north of Australia, the authors have found that a study carried out on aboriginal women has found an increase in the prevalence of the infection in T. vaginalis with age. 12,13 According to other authors, unlike Chlamydia trachomatis and N. gonorrhoeae, the young age is not a risk factor of trichomoniasis. The prevalence of T. vaginalis appears to increase with age for both sexes, perhaps due to the nature frequent asymptomatic infection and consequently the persistence of untreated infections.…”
