To evaluate the impact of human immunodeficiency virus (HIV) on human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN), a study was conducted of 147 HIV-seropositive and 51 HIV-seronegative prostitutes in Nairobi, Kenya. Among the women infected with HIV, 10 (7%) had signs or symptoms of significant HIV-related disease, and the remaining 93% were asymptomatic. The prevalence of cervical HPV DNA was 37% among HIV-seropositive women and 24% in HIV-seronegative women (odds ratio [OR] 1.7, 95% confidence intervals [CI] 0.8, 3.6, after adjusting for potential confounding factors). Genital warts, cervical HPV DNA, and cytologic findings consistent with CIN were all significantly associated with younger age and fewer years of prostitution, but were unrelated or weakly related to number of sexual partners per week or frequency of condom use. In a subset of 63 women with evaluable Papanicolaou smears, CIN was found in 50% of the women with HPV but only in 8% of those without HPV (adjusted OR 7.2, 95% CI 1.6, 32.1, P = 0.006). However, CIN was unrelated to HIV seropositivity (prevalence of 26% among HIV-seropositive women and 24% in HIV-seronegative women). Among women with cervical HPV DNA, HIV infection was not associated with an increased prevalence of CIN (47% prevalence among women with HIV versus 57% prevalence among women without HIV). Thus, in this population of HIV-seropositive women, most of whom had CDC Stage II or III infection, there was no demonstration of an adverse impact of HIV on CIN.

In HIV-infected men, human papillomavirus (HPV) infection is strongly linked with the development of anogenital lesions but is not a sufficient factor to explain the neoplastic transformation of such lesions. We investigated the association between HPV and herpesvirus infections in penile and anal lesions from 54 HIV-seronegative and 54 HIV-seropositive men by means of colposcopy, histopathology and in situ hybridization. Our patients showed condyloma acuminata (39%), papular warts (35%) and macular warts (26%). High-grade lesions were predominant in the HIV+ men, whereas low-grade lesions were more frequent in the HIV- men. In the HIV+ group, potential oncogenic HPV were the most frequently detected (83.4%) whereas the "low-risk" HPV were found chiefly in HIV- men (62.1%). The CD4 number was lower in patients showing "high-risk" HPV than in men showing lesions without HPV or with non-oncogenic HPV. HPV types 6/11 were found mainly associated with koilocytosis or with AIN(PIN)I. Oncogenic HPV were more often detected in AIN(PIN)II-III. The herpesviruses DNA detection revealed a higher prevalence of HSVI and -2 than CMV and EBV in the studied biopsies. The frequency of HSV and CMV detection was higher in the HIV+ than in the HIV- men. A link was found between the "high-risk" HPV and the CMV detection whatever the population considered. The detection in HPV lesions of other sexually transmitted viral agents could therefore represent an important means of preventing progression of the anogenital disease, especially in immunosuppressed patients.

In recent years, the antiviral armamentarium has expanded considerably. Currently available agents are virustatic, inhibiting specific steps in the process of viral replication. No agent is active against nonreplicating or latent viruses. Acyclovir is useful in the treatment of genital herpes, herpes simplex encephalitis, mucocutaneous herpetic infection, varicella infection in the immunosuppressed host, and herpes zoster infection in the normal and the immunosuppressed host. It can also be used for prevention of herpesvirus infection in immunocompromised patients. Ganciclovir is indicated for the treatment of cytomegalovirus retinitis in patients with acquired immunodeficiency syndrome (AIDS) and is effective in the management of organ-specific cytomegalovirus infection in other immunocompromised patients. Chronic hepatitis C and condyloma acuminatum due to human papillomavirus respond to therapy with interferon alfa-2b. Patients with human immunodeficiency virus infection and CD4 lymphocyte counts of less than 500 cells/mm3 should be treated with zidovudine. Amantadine is useful in a therapeutic and prophylactic role in the management of influenza A virus infection. With the expanded use of and indications for antiviral therapy, clinically significant resistance to these agents has been encountered with increasing frequency.

Thirty-two (18%) of 181 children cared for at our institution who were infected with the human immunodeficiency virus type 1 (HIV-1) were first seen, and HIV was diagnosed, when they were 4 years of age and older. Initial complaints or diagnoses for these children included the following: hematologic disorders (5) (3 idiopathic thrombocytopenic purpura, 1 neutropenia, 1 anemia); recurrent bacterial infections (10); Pneumocystis carinii pneumonia (3); developmental delay (1); skin disorders (2) (1 genital wart, 1 chronic zoster); weight loss (3); malignancy (1); and nephropathy (1). Eight children were referred for evaluation because of maternal HIV-1 infection. The risk factors for HIV-1 infection included maternal/perinatal exposure (22), perinatal blood transfusion (6), blood transfusion during infancy (2), and sexual abuse (2). Ten (31%) of the 32 children have subsequently died. The longest survival from perinatal infection was 12 years. HIV-1 infection in children can result in a prolonged clinical latency and can masquerade as other pathologic conditions. The absence of clinical symptoms in older children at risk for HIV-1 infection should not deter HIV testing.

In the US and globally women are contracting the human immunodeficiency virus (HIV) and developing the acquired immunodeficiency syndrome (AIDS) the fastest. Worldwide, HIV is transmitted primarily through heterosexual intercourse. In the US, the proportion of women who have contracted AIDS by heterosexual transmission has increased from 11% in 1984 to 34% in 1990. Women are at a greater risk than men for transmission by heterosexual intercourse as the ratio of women to men who acquire AIDS by heterosexual transmission is 3 to 1. Furthermore, 25% of AIDS cases caused by heterosexual transmission or iv drug use occurs in women. Although women often develop HIV-related serious gynecologic problems, including cervical cancer and refractory vaginal candidiasis, these conditions do not fall within the Centers for Disease Control definition of AIDS. Women who have gynecologic symptoms are not diagnosed as having AIDS, are not eligible for AIDS benefits, and live half as long as men do once they are diagnosed as being HIV infected. Little is known about the characteristics of HIV infection or AIDS in women. Sexually transmitted diseases (STDs) seem to act as cofactors for HIV infection. The human papilloma virus or genital warts, the herpes simplex virus, syphilis, chancroid, recurrent vaginal candidiasis, abnormal Pap smears, cervical neoplasias, and pelvic inflammatory disease have been associated with HIV infection in women. HIV infection should be considered in all women with symptoms of any of these disorders. Nurses must first become aware of the clinical manifestations of HIV infection specific to women. Nursing interventions should educate about safer-sex including condom use with nonoxynol 9, and the risks of sharing needles. Strategies must be developed that provide empowerment skills and are sensitive to the women's cultural, religious, and ethnic background, beliefs, and values.

Over a 12 month period, 32 teenage girls attended the sexually transmitted disease clinic in the Mater Misericordiae Hospital, Dublin for the first time, accounting for 17.8% of all first visits. Their mean age was 18.2 years (range 15-19 years). Twenty-four (75%) were from social class V. Five (15.6%) were abusing drugs. The mean age of first coitus was 16.1 years (range 13-19 years). The mean number of sexual partners was 1.8 (range 1-5). Four (12.5%) had been sexually abused in the past. Fourteen (43.8%) had never used contraception. Twenty-three (71.9%) were nulligravidae: 2 were diagnosed as being pregnant in the clinic. Twelve (37.5%) were unaware of cervical cytology screening. Of 29 having intercourse without condoms, none considered themselves to be at risk of contracting HIV from their present partner. A total of 26 diagnoses were made in 23 patients (71.9%). The most common diagnosis was ano-genital condylomata acuminata (6, 18.8%); Chlamydia trachomatis was located in 2 patients and Neisseria gonorrhoea in one. Mild to moderate dyskaryosis was reported in 4 cervical smears (12.5%). This data highlights the need for priority targeting of this high risk group.

Cutaneous manifestations are common in patients infected with HIV and tend to be more frequent as immunodeficiency progresses. It remains, however, unclear which or how many with HIV-1 infection will develop skin disease. This paper presents and describes the commonly reported skin diseases occurring in people with HIV-1 infection. Observed infections include herpes zoster, herpes simplex, chancroid, syphilis, condylomata acuminata, oral hairy leukoplakia, molluscum contagiosum, candidiasis, bacterial infections, dermatophytosis, and scabies. Noninfective conditions such as pruritic papular eruption, seborrhoeic dermatitis, psoriasis, and others may also present. Regarding disease etiology, a transient maculopapular rash may present in the initial stage of HIV infection. Seborrhoeic dermatitis, persistent genital ulcer disease, pruritic papular eruption, and/or a variety of scaling dermatoses may then be observed during the otherwise asymptomatic phase. Kaposi's sarcoma is the most frequent skin tumor associated with HIV disease. It is also observed that skin manifestations of adverse reactions to drugs occur more frequently in patients with HIV disease than in immunocompetent patients. In closing, most skin diseases associated with HIV disease respond well to standard treatment regimens. Relapses and/or recurrences are, however, frequent among these patients.

The case of an HIV-seropositive man with gonorrhea, syphilis, genital warts, and chancroid is described. Multiple sexual partners, genital ulcer diseases, and lack of circumcision may have predisposed him to HIV infection. As indicated by his CD4/CD8 ratio of 0.5, his immunological status was not very compromised. Other factors were therefore probably behind these multiple sexually transmitted diseases (STD). This 30-year old man was inadequately treated for a long time for urethral discharge and genital ulcer disease, and ultimately collapsed on the job with a comprised central nervous system. Bacterial infection related to the multiple STDs could certainly have caused this collapse. The time demands of this man's work, the lack of medical facilities to diagnose and treat such conditions, his unprotected sexual behavior with multiple partners, and broader socioeconomic conditions which separate wage- earning males from their families in Africa conspire to produce multiply-afflicted cases such as these.

106 black males completed questionnaires on attitudes and knowledge related to condom use and AIDS. Most were enrolled within their 1st 3 years of college in the southern US, and were of average age 23.5 years. 88% were single and never married. 27 reported always using condoms during sex, 31 did not use them and had low intentions of so doing, and 48 reported high intentions to use condoms. Knowledge about AIDS was, however, extremely high across the study sample. Those with low intention to use condoms were significantly more negative about condom use, and reacted more vehemently when partners inquired about sexual history, when a partner refused sex without condom, or when they perceived condoms as interfering with foreplay and sexual pleasure. A significantly larger percentage of low intenders were treated for gonorrhea, syphilis, herpes, and genital warts than steady condom users and high intenders. While a comparatively larger percentage of low intenders reported anal sex and sex with prostitutes, the group overall felt at lower risk for AIDS than men from the other 2 groups. Although low intenders used marijuana comparatively more often, drug use did not differentiate the 3 groups. Since some of these men continue to engage in risky sexual behavior despite their awareness of HIV transmission modes and AIDS, alternative interventions are needed to target and change some of their attitudes and behaviors.

Since July 1986 we started with following all patients with condylomata acuminata including HIV-testing and human papilloma virus (HPV) identification by DNA-DNA-hybridisation (southern blot). Seventy patients are included, 39 of them are seropositive. The ratio male to female is 59 to 11, in seropositives 35 to 4, in negatives 24 to 7. The average age is 28 and 31 years respectively. The number of homosexuals and junkies is significantly higher in seropositives. Seventeen patients are in HIV-stage II, 11 in stage III and 10 in stage IV according to CDC-classification. Characteristic for the seropositives was an extensive growth on the rectal mucosa and the very rapid growth of initially subtotally resected lesions in order to prevent stenosis. Sixty-five patients were treated by one stage radical operation with electrocauter. Surprisingly recurrency is more frequent in seronegatives, however, the lesion is much smaller in this group. A hypothesis to explain this observation is brought forward. Postoperative complications occurred only in HIV-stages III and IV. We therefore recommend single shot antibiotic prophylaxis in these patients. The HPV-identification showed no malignancy associated HPV-types in both groups but a higher incidence of HPV 11 in higher HIV-stages which we cannot explain. We conclude from our series that, if operation is indicated, one stage radical electrocoagulation of condylomata acuminata is a necessary procedure in seropositive patients and a save one in negative patients but antibiotic prophylaxis should be given in stage III and IV. Anal condylomata acuminata are a hint for possible HIV-positivity.
