Genital human papillomavirus infections: Number 193 - June 1994 (Replaces no. 105, June 1987)

Oral and vulvar changes in pregnancy

The endocrinologic, immunological, and vascular changes that occur during pregnancy are far-reaching. These systemic factors produce profound local impact on the physiology and pathology of the oral cavity, vagina, and vulva. Physiological changes can be expected and tolerable or of such severity that they are viewed as pathological. Existing disease can be exacerbated and dermatoses specific to pregnancy can erupt. Each of these conditions can pose potentially challenging treatment considerations.

Type-Specific HPV Testing as a Predictor of High-Grade Squamous Intraepithelial Lesion Outcome after Cytologic Abnormalities

OBJECTIVE

Human papillomavirus (HPV) risk assignment influences management after a cytologic diagnosis of atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL). This study addressed whether type-specific HPV testing predicts risk of biopsy outcome of high-grade cervical intraepithelial neoplasia (CIN 2,3).

MATERIALS AND METHODS

A total of 162 ASCUS or LSIL diagnoses with colposcopic follow-up were evaluated and placed in 3 groups: Analysis 1: (high-risk HPVs including types 53 and 66; Analysis 2 (high-risk HPVs excluding types 53 and 66); and Analysis 3 (high-risk HPVs including type 53 and excluding type 66).

RESULTS

CIN 2,3 biopsy results followed low-risk HPVs in 0%, 3%, and 0% of scenarios 1, 2, and 3, respectively; 21%, 40%, and 27% of smears were classified as low risk, respectively. Of HPV 53 infections, 13.6% had CIN 2,3 biopsy outcomes.

CONCLUSIONS

Type-specific HPV testing accurately classifies a group of HPV-positive LSIL/ASCUS cases at low risk for CIN 2,3 at the first follow-up visit. Classifying HPV 53 as low-risk increases slightly the proportion of HSIL outcomes in the low-risk group, but may not increase cancer risk. HPV 53 merits designation as a high-risk HPV based only [corrected] on the proportion of CIN 2,3 in follow-up biopsy.

Genital and perianal warts: new treatment opportunities for human papillomavirus infection

Human papillomaviruses are among the most common sexually transmitted diseases in the United States. Genital warts are a common phenotypic expression of human papillomaviruses, affecting 1% of the population; therefore, the obstetrician/gynecologist will invariably be required to advise and treat patients with this clinical manifestation. Issues essential in the diagnosis, counseling, and management of patients with genital warts will be examined, including epidemiology, transmission, molecular biology, and host immune response. This review will also provide the health care professional with a thorough examination of the new patient-applied treatment opportunities for anogenital condyloma, in addition to an overview of current provider-administered therapies, to assist in patient management.

AIDS-related malignancies

In the US over one million persons are currently infected with the HIV, over half a million have had AIDS, and over 300,000 have died from AIDS. Worldwide, it is estimated that more than 17 million people are currently infected with HIV, and over 1,200,000 cases of AIDS have been reported to the World Health Organization. By some estimates, up to 40% of patients with AIDS will ultimately develop some form of cancer. Non-Hodgkin's lymphoma, Kaposi's sarcoma and invasive cervical cancer have a higher incidence in persons with HIV infection and all three are AIDS-defining illnesses. In addition, several reports suggest that a number of other malignancies may occur at an increased incidence in persons with HIV infection, including squamous-cell carcinoma of the head, neck and anus, plasmacytoma, melanoma, small-cell lung cancer, basal-cell cancer, and germ-cell tumours. Clinicians should become familiar with HIV-related malignancies as their incidence is expected to further increase as more effective therapies for HIV and associated opportunistic infections allow patients to live longer in an advanced state of immunodeficiency. In the current article, we will review the clinical and therapeutic aspects of the most common AIDS-related malignancies including non-Hodgkin's and Hodgkin's lymphomas, Kaposi's sarcoma and anogenital epithelial neoplasias.
