Cytology of the 'penile' neovagina in transsexual women.

OBJECTIVE: The primary objective was to describe the neovaginal cytology in transsexual patients (n = 50) treated with the inverted penile skin technique. Secondary objectives were to compare our cytological findings with patient characteristics including use of oestrogens, sexual orientation and penetrative intercourse. METHODS: The medical and surgical history, sexual orientation and whether there was a current relationship were ascertained. A speculum examination was followed by microscopy of a Pap smear of the neovaginal vault. RESULTS: Well-preserved nucleated squamous cells were found in 72%. The correlation between their presence and sexual orientation was highly significant (P = 0.016), with those not sexually interested and homosexually oriented all having nucleated cells on the Pap smear. However, the correlation between these cells and penetrative intercourse failed to reach significance. Four samples showed atypical squamous cells of undetermined significance, all were negative for high-risk human papillomavirus (HR-HPV) types. One patient showed a low-grade squamous intraepithelial lesion that was HR-HPV positive. There was a significant correlation between the presence of cytological lesions and sexual orientation (P = 0.006). Four percentage of the specimens showed Döderlein bacilli. Inflammation was found in 30.6% of samples with squamous cells. CONCLUSIONS: The penile skin-lined neovagina of transsexual women can reflect the cytological findings present in biological women. However 'normal' cervical cytology, with superficial, intermediate and parabasal cells as well as Döderlein bacilli, was found in only 4% of transsexual women. Although one patient's Pap test showed koilocytes and was HR-HPV positive, no high-grade squamous intraepithelial lesions were identified.

Natural history and clearance of HPV after treatment of precancerous cervical lesions.

AIM: To assess the clearance rate of human papillomavirus (HPV) after out-patient treatment of cervical intraepithelial neoplasia (CIN). METHODS AND RESULTS: A total of 122 Nicaraguan women with HPV DNA-positive and histologically confirmed CIN lesions were included in the study. Fifty-five patients with CIN1 and 67 with CIN2-3 were treated by cryotherapy and loop electrosurgical excision procedure (LEEP), respectively. Follow-up visits were scheduled at 6 weeks, 6 months, 1 year and 2 years. Investigations included cytology, HPV DNA testing and colposcopy/biopsy if needed. The clearance rate of HPV was calculated by multivariate logistic regression. Immediately after treatment, a pronounced decrease in presence of HPV was observed in both groups, with a significantly higher clearance in the LEEP group than in the cryotherapy group (P = 0.019). Subsequently, clearance continued over time and was similar between the cryotherapy group and the LEEP group (P = 0.73). Approximately the same detection rates were obtained for persistence of all HPV types and for high-risk types separately: 43.9, 37.6, 29.9 and 17.7% in the cryotherapy group and 24.9, 20.3, 15.3 and 8.4% in the LEEP group at 6 weeks, 6 months, 1 year and 2 years, respectively. CONCLUSIONS: Out-patient treatment of precancerous lesions of the cervix usually results in clearance of HPV. Both LEEP and cryotherapy are highly effective methods of eradicating HPV. HPV DNA testing may have added value in the follow-up of patients.

Human papillomavirus DNA detection in women with primary abnormal cytology of the cervix: prevalence and distribution of HPV genotypes.

OBJECTIVES: In this study, we focus on the prevalence and occurrence of different anogenital human papillomavirus (HPV) genotypes in a first abnormal cervical screening test, and correlate HPV genotyping with the cytological diagnosis on thin-layer liquid-based preparations in routine gynaecological screening. METHODS: Out of 780 abnormal smears, 513 tested positive for HPV. All 25 different HPV types were identified by Line Probe Assay. RESULTS: The prevalence of high-risk HPV types increased from 72% in atypical squamous cell of undetermined significance to 94.5% in high-grade intra-epithelial lesion (HSIL). Co-infection with multiple HPV types was predominantly found in HSIL (35.8%). In the HSIL group the most common HPV types were 16, 52, 51 and 31; type 18 was rarely present. CONCLUSION: The role of types 31, 51 and 52 should be considered in future studies on vaccine development.
