Human Papillomavirus Segregation Patterns in Genital and Nongenital Warts in Prepubertal Children and Adults

This study compared the segregation patterns of human papillomavirus (HPV) in genital and nongenital warts in prepubertal children and adults. HPV 2 was detected in most nongenital warts in children and adults, whereas neither HPV 6 or 11 was detected at nongenital sites in either group with the use of in situ or Southern blot hybridization analyses. Of nine genital tract lesions in children. HPV 2 was detected in two and HPV 6 or 11 in six. More than 90% of cases of regional tract condylomata in adults contained HPV 6 or 11. HPV 2 was not detected in any of 99 genital tract lesions in adults. It is concluded that HPV 6/11 cannot proliferate at nongenital cutaneous sites and HPV 2 can proliferate in the genital tract of children but not adults. Thus, the detection of HPV 6 or 11 in a genital wart in a child implies, assuming cutaneous transmission, infection from a genital site, whereas the detection of HPV 2 presumes nongenital transmission.

The Interferons: A Clinician’s View

Therapy with interferon remains in its infancy. At present, appropriate methods and protocols for treatment of malignant melanoma and other tumors are being formulated. The drug offers promise for patients with basal-cell carcinoma in surgically difficult or cosmetically troubling locations. Older debilitated patients might find this mode of therapy welcome compared with more destructive surgical techniques. At some later date, interferon might be useful to treat resistant warts of the palms, soles, or genitalia.

Human papillomavirus--a study of male sexual partners.

Male sexual partners of a cohort of women with genital-tract abnormalities which were associated with human papillomavirus infection were examined for evidence of infection with human papillomavirus. Of the 214 male partners who were examined, 93.5% had visible genital lesions. Of the 196 lesions that were biopsied, 72.5% showed histological evidence of infection with human papillomavirus, and only 20.4% of subjects with histological evidence of human papillomavirus were aware of a lesion. An unexpectedly high proportion (6.1%) of lesions on which a biopsy was performed, particularly those with flat, red, indurated morphology, also showed histological evidence of penile intraepithelial neoplasia. This was not significantly more common among the partners of the women with cervical intraepithelial neoplasia than it was among the partners of the women with other evidence of genital human papillomavirus infection. Penile intraepithelial neoplasia was significantly (P less than 0.001) more common among subjects with no history of non-genital warts. We conclude that the male partners of women with human papillomavirus-associated lesions are very likely to be infected with human papillomavirus, and thus may act as a significant reservoir for the reinfection of their female partners. As the awareness of human papillomavirus-associated lesions was low among the male partners, colposcopic examination and treatment of their male partners, and/or barrier contraception, may be a necessary part of the management of women who are undergoing treatment for human papillomavirus-associated genital disease.
